STRENGTH AND STIFFNESS CHARACTERISTICS OF AXIALLY LOADED REINFORCED CONCRETE COLUMNS WITH DIFFERENT TYPES OF CONCRETE |
Author : Saad Khalaf Mohaisen, Aamer Najim Abbas and Ali Sabah Ahmed |
Abstract | Full Text |
Abstract :The current paper is a report on the preparation and testing of 10 reinforced
concrete column specimens of (120x120) mm2
cross section and 1000 mm height, for
the experimental clarification of the behavior of columns under the influence of pure
axial loads. The research addresses the influences of some parameters and conditions
on the mentioned behavior, including concrete type (normal strength, high strength or
modified reactive powder concrete), the amount of reinforcement and the percentage
of steel fibers. The effects of the above variables on the ultimate capacity, failure mode,
stiffness, ductility and axial load-lateral displacement behavior were studied. It has
been found that increasing the compressive strength and steel reinforcement ratio lead
to increasing the ultimate capacity and stiffness of the tested columns. The effectiveness
of increasing the steel fibers ratio is manifest in increasing the ultimate strength,
ductility, and decreasing the stiffness and the ductility of the tested columns.

EXPERIMENTAL STUDY OF CONTINUOUS RC BEAMS STRENGTHENED WITH CFRP FABRICS UNDER TORSION |
Author : Saad Khalaf Mohaisen |
Abstract | Full Text |
Abstract :In the last ten years or a little more, CFRP strips and fabrics have been successfully
externally bonded to rehabilitate the concrete structures. Most of the previous research
focused on the use of CFRP as an enhanced material to improve flexural, shear,
ductility and ductility behaviour and confinement of concrete structural members, while
limited attention was paid to the investigation of strengthened reinforced concrete (RC)
members against torsion, particularly continuous concrete beams. This study aims to
detect experimentally the CFRP strengthening technique for continuous RC beams
exposed to pure torsion. The experimental program includes investigation of two
groups of beams; the first group was composed of twelve un-strengthened beam
specimens and the second one includes a total of twelve strengthened beam specimens;
all were experienced under pure torsion. Factors considered in the testing program
included the effects of concrete compressive strength and the angel of a twist. The angle
of twist at each level of force applications, torque at first crack, ultimate torque was to
be in comparison with for control and strengthened beams. The outcomes of the tests
indicated that all beams wrapped with CFRP fabrics resulted in improvement in
tensional resistance as compared with the reference specimens |

Author : Ahmed Samir Naje, Hussein A. M. Al-Zubaidi, Zaid Abed Al-Ridah and Isam M. Ali |
Abstract | Full Text |
Abstract :The purpose of this article is to evaluate the possibilities of using denitrification
dephosphatation to enhance biogenic compounds removal in the wastewater treatment
plant using a separated nitrification process on a fixed-film. The analysis was based on
the multi-variant simulations of the combined system, fixed-film activated sludge
performance. Activated sludge ASIM 2D model which is linked to the model of
pollutions transformations in fixed-film was used. The analyses were performed based
on the input parameters (wastewater averaged daily rate, pH, COD values, total
suspended solids, total Kjeldahl nitrogen, nitrate nitrogen, total phosphorus, and
alkalinity). The results indicated that there is a possibility of including fixed-film in the
activated sludge technology in order to improve nitrogen and phosphorus removal from
the wastewater. Nitrification process will be performed in fixed-film, whereas nitrogen
and phosphorus removal from the wastewater will be performed in anoxic chambers
which are operated by the activated sludge technology. Denitrifying dephosphatation
process guarantees a high level of total phosphorus reduction (81%) if the whole easily
decomposable substrate is consumed by microorganisms in the anoxic chamber in the
presence of enough nitrates |

Abstract :The Quran contains almost braches of knowledge and courses or fields of studies.
It also covers every aspects of life. Obviously, it is stated in the Quran that there are
three different types of admission to it. The three types of human beings to comprise;
the believers who believe in all its contents, the infidels who absolutely in rejecting and denying the truth and opposing the Quran and its message, as well as the hypocrites
who use the Quran and twist it to suit and justify their fraud. The need to understand
the essence of each group according to the perspective of the Quran is very important.
Hence, the study of the unbelievers is done to understand the true nature of this group.
This study attempts to extract the pattern of extraction for the Ba?ar word for
unbelieving people which involves the entire verse in the Quran. This research is a
qualitative study using summative content analysis method. Findings show that, the
Ba?ar sentence for the human category does not tell us about; (i) the attributes of this
group, (ii) the factors that cause the rejection of the Quran, and (iii) the rewards that
Allah has provided and reserved for this group in the world or the hereafter. |

CONDITION PREDICTION MODELS OF DETERIORATED TRUNK SEWER USING MULTINOMIAL LOGISTIC REGRESSION AND ARTIFICIAL NEURAL NETWORK |
Author : Dr. Basim Hussein Khudair, Dr Ghassan Khalaf Khalid and Rehab Karim Jbbar |
Abstract | Full Text |
Abstract :Sewer systems are used to convey sewage and/or storm water to sewage treatment
plants for disposal by a network of buried sewer pipes, gutters, manholes and pits.
Unfortunately, the sewer pipe deteriorates with time leading to the collapsing of the
pipe with traffic disruption or clogging of the pipe causing flooding and
environmental pollution. Thus, the management and maintenance of the buried pipes
are important tasks that require information about the changes of the current and
future sewer pipes conditions. In this research, the study was carried on in Baghdad,
Iraq and two deteriorations models multinomial logistic regression and neural
network deterioration model NNDM are used to predict sewers future conditions. The
results of the deterioration models application showed that NNDM gave the highest
overall prediction efficiency of 93.6% by adapting the confusion matrix test, while
multinomial logistic regression was inconsistent with the data. The error in prediction
of related model was due to its inability to reflect the dependent variable (condition
classes) ordered nature |

Author : T. M. Mezher, Q. A. Jabal and A.T. Zwain |
Abstract | Full Text |
Abstract :The research aims to use waste materials in concrete to decrease cost of concrete
since that waste materials in Iraq is highly available. Waste marble is very good
example to use it in concrete as coarse aggregate and excellent material to produce
very good quality concrete. This research study the using of waste marble as coarse
aggregate and using steel pins as a low cost local steel fibers as percentages of total
volume in concrete and study the effect on mechanical properties of concrete. Using
marble aggregates in concrete increase the compressive, tensile and flexural strength
of concrete comparing with ordinary aggregate concrete. Ordinary reference mix
concrete with 1:1.1:2.2 gives about 50.89 MPa, while using marble aggregate with
same mix proportions gives 57.07 MPa, thus, that gives low cost for production of
concrete because 60%to 70% of the volume of concrete is aggregates . The effect of
steel pins as it used in marble aggregate concrete is also very good , using 0 %, 0.1%
,0.2% , 0.3%, to 1% of steel pins in mixes. The compressive increase by adding steel
pins from 57 to 72.14 MPa. Flexural strength had very significant increment when
adding fibers and it rise from 3.9 to 8.6 MPa. |

Author : Ayushi Raichoudhury |
Abstract | Full Text |
Abstract :Education has been considered as an important tool for all sorts of issues. This
paper intends to study the relationship between educational level, PMJDY awareness
and financial inclusion in the district of Puri, Odisha. Data were collected with the
help of a survey technique from 348 respondents in both rural and urban areas of Puri
district. Multistage purposive sampling method was used. Descriptive statistics of the
data collected reveals that financial awareness/ financial inclusion increases with
education level. It is seen that respondents with primary education and below
secondary education have more financial inclusion and PMJDY awareness due to the
reason that most of the respondents belong to that category. It is also evident that
households with graduation and above are also more likely to be financially aware
and financially included. However, to have a complete understanding of the inter

ESTATE SURVEYORS AND VALUERS INVOLVEMENT IN OUTDOOR ADVERTISING BILLBOARDS VALUATION IN LAGOS, NIGERIA |
Author : Oni, A.S; Oloyede, S.A.; Durodola, D.O; Ayedun, C.A. and Akinjare, O |
Abstract | Full Text |
Abstract :Outdoor advertising billboards, especially the off-premise, stand-alone types, are
common sights along major thoroughfares in Nigerian cities such as Lagos. They are
attached to real estate, and in most cases, are meant to be permanent structures. They
are developed to provide display spaces for advertisement in exchange for rent, and
thus, they are income producing assets. Their valuation is therefore imperative for
different purposes such as sale/purchase, compensation, insurance, lending and
accounting. This study examined the involvement of estate surveyors and valuers in
the valuation of this outdoor advertising asset in Lagos. By employing the purposive
sampling method, managers of 34 out of 85 outdoor advertising companies and 147
out of 366 estate surveying and valuation firms in Lagos were sampled through the
use of close-ended questionnaires. The 29 questionnaires retrieved from the outdoor
advertising companies and the 127 retrieved from the estate surveying and valuation
firms were analysed using descriptive statistical tools. The study revealed that the
involvement of estate surveyors and valuers in the valuation of billboards in Lagos,
Nigeria was modest as only 146 cases out of 280 activities requiring valuation
(52.1%) between 2012 and 2017 were valuations carried out by estate surveyors and
valuers. Other unprofessional basis were resorted to in determining values of
billboards. Also, activities such as sale/purchase of billboards and, compensation for
billboards compulsorily acquired, requiring valuations, were seldom carried out
thereby restraining the involvement of valuers. Outdoor advertising companies should
embrace the use of estate surveyors and valuers more in all their activities requiring
valuation as this is the only way to achieve transparency, accountability and
compliance with regulations. Firms of Estate Surveyors and valuers too should
prospect more for valuation from all stakeholders to expand their areas of operation,
build capacity and create employment for up-coming estate valuers in Nigeria |

EXPERIMENTAL STUDY ON THE BEHAVIOR AND STRENGTH OF REINFORCED CONCRETE CORBELS CAST WITH SELF-COMPACTING CONCRETE INCORPORATING RECYCLED CONCRETE AS COARSE AGGREGATE |
Author : Emadaldeen A. Sulaiman, Dr. Jamal A. Samad Khudair |
Abstract | Full Text |
Abstract :This paper deals with the effect of using recycled concrete aggregate as a partial
replacement of coarse aggregate in self-compacting concrete, on the structural
behavior of reinforced concrete corbels. From the previous researches, there is no
studies deals with the effect of using this type of aggregate on the structural behavior
of corbels, and also the use of RCA has an economical and environmental benefits
Three replacement ratios were considered 25%, 50% and 75%. All mixes (with and
without RCA) have almost same compressive strength at age of 28days which is equal
to (35MPa) with a tolerance of (±3MPa).For this purpose, an eleven reinforced
concrete corbels were cast and divided in to three groups (A, Band C). Each group
deals with specific problem. Different parameters which effect the behavior of corbels
were studied and include replacement ratios of natural coarse aggregate by recycled
concrete aggregate (RCA), amount of horizontal reinforcement (Ah) and amount of
main tension reinforcement (Asmain).
In order to get same compressive strength of concrete mixes made with natural
and with recycled concrete aggregates, the quantity of cement was increased by
(1.25%, 3.75% and 10%) for mixes containing (25%, 50% and 75%) recycled
concrete aggregate respectively compared with SCC made with natural coarse
aggregate.
The experimental results of corbels show that the ultimate load capacity of corbels
in group Atested with a/d of 0.34 and made from SCC with (25%, 50 and 75%) RCA
was decreased by (2.22%, 7.4%, and 12.34%) respectively compared with corbel
made from SCC without RCA. While in group B, all corbels casted with 50%RCA and
have the same main tension reinforcement, a/d=0.34, corbel dimensions and concrete
compressive strength and the only difference was in the amount of horizontal
reinforcement. The results showed that when the amount of horizontal reinforcement
(stirrups) was increased from zero to 2Ø6mm, the ultimate load increased by (15.55%). While when the horizontal reinforcement was increased from 2Ø6mm to
3Ø6mm the ultimate load increased by 50%. Also the ultimate load was increased by
76.22% when the amount of horizontal reinforcement increased from zero to 4Ø6mm.
In group C, all corbels were casted with50% RCA and tested under a/d=0.6. All
corbels having the same geometry, horizontal reinforcement and a/d ratio and the
only difference was in the main tension reinforcement. From the results it was noted
that the increase in main tension reinforcement from 2Ø10mm to 3Ø12mm causes an
increase in ultimate load by about 19.04%. When the main tension reinforcement was
increased from 2Ø10mm to 2Ø16mm, the ultimate load was increased by 22.61%.
There for it can be concluded that the recycled concrete aggregate can be used as
a partial replacement of natural coarse aggregate to produce self-compacting
concrete mixes and the behavior of corbels cast with SCC containing RCA is
acceptable |

NUMERICAL INVESTIGATION OF THE STRUCTURAL BEHAVIOR OF REINFORCED CONCRETE BEAMS WITH CRUSHED CONCRETE AGGREGATE |
Author : Ahmad L. Al-Mutairi, AliK. Al-Asadi and Hany Ahmed Abdalla |
Abstract | Full Text |
Abstract :Recycling of waste materials produced from the construction and demolition
activities is becoming a demand for modern societies willing to achieve environmental
sustainability. To date, the use of crushed concrete aggregate (CCA) in replacement of
natural coarse aggregate to produce high quality concrete is very limited. This can be
attributed to the missing information on the properties of the original concrete before
crushing, the limited data that clarifies the influence of using CCA on the material
properties of the concrete mixture as well as the overall structural behavior of the
reinforced concrete element in which it is used. An experimental testing program has
been conducted on reinforced concrete beams to assess the influence of CCA
replacement ratio on their structural performance and the results have been briefly
discussed in this paper. The primary aim of the study presented herein is to
numerically evaluate the influence of the concrete compressive strength (fcu) and the
shear span to depth ratio (a/d) on the structural performance of reinforced concrete
beams casted with two different concrete mixtures incorporating 0% and 100% CCA.
Accordingly, ten beams have been modelled using ANSYS finite element software with
two control beams being validated with the experimental data. The results
demonstrate the increase of the load carrying capacity and ductility of beams with
100% CCA with increasing the fcu. On the contrary, increasing the shear span to depth
ratio leads to the reduction in the capacity of the beams casted with the two different
concrete materials. As a final conclusion, the results of the performed numerical
analysis designate undesirable structural performance of the concrete beams with
100% CCA. Therefore, it is not recommended to use concrete mixtures with full replacement of natural coarse aggregate by CCA in casting concrete structural
members where ductile behavior is indispensable |

SUSTAINABLE SOLUTIONS FOR EXPOSED CONCRETE SURFACES TO CLIMATIC INFLUENCES – WITHIN VARIOUS REGIONS: AN INDUSTRIAL-GEOGRAPHIC LETTER TO CIVIL-CONSTRUCTORS |
Author : Mahmood M. H. Alshammari, Ali k. M. Al-Nasrawi and Ali Jabbar Abdullah |
Abstract | Full Text |
Abstract :Environmental factors significantly influence concrete surfaces. Infrastructures
are affected by variety climatic conditions including: extreme temperatures,
droughts, moist and humid conditions or even inundation, and they are more likely to
experience negative influences on their concrete surfaces. Thus, this research aims to
identify sustainable solutions to decrease the vulnerability of concrete exposed to
climatic and environmental influences by assessing the response of concrete surfaces
to high solar radiation, high temperatures, and wet weather conditions.
Our results within warm and tropical regions show that temperature fluctuations
lead to expansion and shrinkage of concrete, particularly in buildings with poor
thermal insulation. Including iron components are prone to these shrink-swell
processes, causing crack development and expansion over time. Then, this study is
suggested some responding solutions including; plant covering over concrete surfaces
of the structures as well as use of some light-coloured silicates to reduce solar
radiation absorption.
Another focus of this study is to analyse the roles of some environmental factors
including salinity, humidity, rain, and snow that may influence the concrete surfaces,
particularly within wet and coastal regions. Previous studies show that the
permeability of concrete surfaces increase the Infiltration of water which can lead to corrosion of iron components, and salt accumulation within cavities, particularly
affecting coastal-zone infrastructures. Thus, a suggestion of high-density, low-porous
concrete to be used to prevent the diffusion of water into concrete surfaces.
The concrete surface problems that are occurring due to various environmental
factors can cause severe damage. The corrosions including peeling process is an
example of such damage that often is not-repairable. Notably, if peeling occurs within
the primary reinforcing structure, the metal bodies are likely exposed to corrosion,
which then requires a greater response to be fixed. Thus, the information provided in
this study yield base suggestions which can support informed decision-making during
planning and construction stages to sustain longer-lasting concrete surfaces under

Author : Abubakar Muhammad Nur, Sanggar Kanto, Darsono Wisadirana and I Nyoman Nurjaya |
Abstract | Full Text |
Abstract :Human civilization in its development follows the process of social change, in accordance with the
rhythm of the times. The life dynamics of the Hibua Lamo community entered the reform era (1998-
1999), leading to a steep road to build the Hibua Lamo community kinship system. The role of local
elites based on local cultural values succeeded in hacking into civil conflict in the Hibua Lamo region.
This study aims to understand and describe thedevelopment dynamics of the Hibua Lamo community,
in Tobelo North Halmahera. Qualitative methods used in this research process, with data collection
techniques through observation, interviews and document studies. The results showed that the wave of
social change changed the existence of local cultural values that has implication to civilization climate
change in Hibua Lamo society. The dynamics of social life in the Hibua Lamo community are mapped
intothree eras: First, the era of "Odora-Ohayangi" (affection). Community social life in the Hibua
Lamo community, from the time of the ancestors to the beginning of 1999, has always been built in a
kinship system based on local cultural values (a culture of mutual respect, mutual acceptance, mutual
recognition and mutual protection), as a basis for social harmony. Second, the "galosiri" (sorrow)
era. The "O tohora-moi"(blood and descendants) kinship climate that always mingles in harmony and
peace, soon turns into conflict. Third, the era of "Hidiai" (improve), or the reconciliation process. The
local elites have a role to unite conflict communities as an effort to hack the steep road to the kinship
system in the Hibua Lamo community, by functioning and empowering the role of customary
institutions as social glue and preservation pillar of local cultural values, which is controlled through
bureaucratic regulation (Regional Government Policy) and social control of Customary Institutions
(Hibua Lamo), as a basis for social harmony |

SEISMIC PERFORMANCE EVALUATION OF A BASE-ISOLATED BUILDING |
Author : U. Wijaya, R. Soegiarso, and Tavio |
Abstract | Full Text |
Abstract :The Lombok and Palu Earthquakes that have recently occurred in Indonesia caused
significant damage. Earthquakes are closely related to damage, landslide, and the loss
of life and economy. However, the causes of these things are not solely due to the
earthquake itself. The cause loss of life and economy caused solely due to the collapse
of buildings that built by humans during an earthquake. To reduce impact loss of life and
economy, Performance Based Seismic Design (PBSD) using based isolator can be one
of the solution. By using PBSD economic considerations the cost of repair after an
earthquake can be predicted. In this study, modeling 12-storey reinforced concrete
buildings located in Yogyakarta Indonesia stands on soft soil using base isolator High
Damping Rubber type (HDR HH090X4S, thickness 20 cm product of Bridgestone). The
average of non-linear dynamic time history analysis of seven ground motion respectively
Denali earthquake 2002, Imperial Valley 1940, Kobe 1995, Loma Prieta 1989,
Northridge 1994, San Fernando 1971, Superstition Hills 1987 was conducted. Seismic
response modification coefficient R was taken respectively 2.5, 3.5, 5.5, and 8. From
these coefficients, the performance of the building is obtained with R 2.5 and R 3.5
performance building in the category of immediate occupancy, R 5.5 and R 8 Category
damage control. Thus the building with R 2.5 and R 3.5 according to FEMA 273 will
produce a building with a repair cost of 25% and repair time only 1 day, so that after
the earthquake the building can resume normal operation. |

EXPERIMENTAL DESIGN ANALYSIS AND COMPARISON OF FORM OF FORECASTLE DECK EDGE USING WAVE SPEED VARIATION USING COMPUTATIONAL FLUID DYNAMICS |
Author : Suharto, Hartono, Sulaiman |
Abstract | Full Text |
Abstract :The purpose of this study is to design experiments to determine the impact of ship
aerodynamics in Indonesia using the Computational Fluid Dynamic method and
compare the impact of fuell consumption and load from experimental testing. Thus, it
can be known in detail about the voltage that occurs up to the final speed of the ship
during testing. In the preparation of this research the first step is to model the end of
the ship using CAD software from the original model used in experimental testing. The
next thing is to determine the value of the mechanical properties of the material and
then put it in the CAE software. In CAE software, it is also determined about the
boundary conditions of the material and then determines the speed. The next thing to
do is the process of meshing the plate and ammunition and after the meshing process
is proceeded to the running process. In contrast to experimental testing where there
are various obstacles, the data produced by testing the Computational Fluid Dynamic
method and experimental testing can sometimes be different. This is because in the
testing process using Computational Fluid Dynamic, conditions are always in optimal
conditions |

EFFECT OF CONSTRUCTION JOINT ON STRUCTURAL PERFORMANCE OF REINFORCED SELF-COMPACTING CONCRETE BEAMS |
Author : Murtada A. Ismael, Yahyia M. Hameed and Haitham J. Abd |
Abstract | Full Text |
Abstract :This paper presents the effect of construction joints on the performance of
reinforced self-compacting concrete slender beams. The experimental program
included casting and testing four beams with dimensions of 125×150×1000 mm. The
first beam is without construction joint as a reference specimen, the second beam is of
horizontal construction joint at mid-depth of the beam, the third beam is of vertical
construction joint at mid-span (maximum bending moment point) and the fourth beam
is of vertical construction joint on fourth-span (maximum shear region). The test
results showed that the effect of construction joint on the ultimate load was more
significant than that on the first crack load, also, the results showed that the beam of
horizontal construction joint gave better structural performance as compared with the
other cases of the construction joint, in which the first crack load decreased 6.7% and
the ultimate load decreased 26.7%as compared with the reference beam. Also the
results showed that the beam with vertical construction joint on the fourth-span
represented the less efficiency case, in which the first crack load decreased 16.7% and
ultimate load decreased 56.2% as compared with the reference beam. Furthermore
the load-deflection becomes less stiff with presence construction joint especially
beyond the first crack load.

Author : Sivakumar Naganathan, Masimawati Abdul Latif, Hashim Abdul Razak, Kamal Nasharuddin Mustapha, Salmia Beddu, B.Mahalingam, G.Elangovan |
Abstract | Full Text |
Abstract :This paper reports an investigational study on the effect of calcium carbide kiln
dust (CCKD) in cement mortar and its resistance towards hydrochloric acid attack.
Mortar with various CCKD replacement levels from 5 to 40 percent by binder weight
were tested. The setting time, consistency, density, compressive strength and the
durability tests were evaluated to measure the effect of CCKD in mortar. The durability was assessed in terms of loss of density and strength when the specimen
were cured in 5% hydrochloric acid (HCL) solution. The results indicate that CCKD
replacement levels from 5 to 20 percent performed on par with control mix in terms of
compressive strength, the loss in density and strength were around 30% under acid
curing. However, 30% and above CCKD replacement percentage showed low density
and compressive strength in both conditions. It is concluded that CCKD can be used
as an effective replacement for cement up to 20 percent without affecting the
performance.

Author : Ameer A. N. Al-jamel and Hayder M.K. Al-Mutairee |
Abstract | Full Text |
Abstract :This research devotes to conduct an investigation into the effects of lateral
reinforcement on the flexural behaviour of Straight Reinforced Concrete Beam
(SRCB). The amount of both longitudinal and lateral reinforcement, beam aspect ratio
(h/d) and shear span of concentrated load to depth ratio (a/d), are considered. The
experimental work includes casting and testing of fifteen SRCB of normal strength with
simple ends. The beams divided into three groups according to h/b ratio which taken
equal to (1.5, 2, and 2.5). The experimental results show that for SRCB with h/b equal
to 2 and under concentrated load at mid-span the ultimate load carrying capacity
increased by (30.8%, and 22.23%) when increasing the shear reinforcement by (50%,
and 100%) respectively. Also, the ultimate strength was increased by about 10.38%
and 16.53% with increment in shear reinforcement of 50%, and 100% respectively for
beams with h/b equal to 1.5 and under two-point load at third point. Finally, the results
appear not only increments in the capacity of ultimate load and decrement in the cracks
width when decreasing the shear reinforcement spacing but also the ductility of the

LEGAL POLICY IN PROTECTION FOR INDONESIAN SEAFARERS |
Author : Adnan Hamid |
Abstract | Full Text |
Abstract :Indonesia as a state of law, which is based on Pancasila and the 1945 Constitution
of the Republic of Indonesia, has a goal to improve welfare for its people wherever
they are. Therefore, it is the duty of the State to protect its citizens who work both
formally and who work informally, both those who work domestically and those who
work abroad. Law No. 18 of 2017 concerning the Protection of Indonesian Migrant
Workers who replaced Law No. 39 of 2004 concerning the Placement and Protection
of Indonesian Migrant Workers is a form of general protection for all Indonesian
workers who work overseas or who are known as Workers Migrants, including sailors
and seafarers. However, the form of protection against seafarers of Indonesian crew
is felt to be inadequate, considering that there are still many sailors of Indonesian
ship crew whose rights are differentiated compared to seafarers from other countries.
The main problem in this paper is to analyze legal policies in the protection of
Indonesian seafarers working overseas. By using normative juridical and sociological
juridical method, this study shows for Indonesian seafarers, both at home and abroad
are entitled to legal protection in accordance with the nature of their work without
exception. This legal protection begins with an agreement between the seafarer and
the employer as stated in the sea labor agreement.

Author : Tamara Kawther Hussein |
Abstract | Full Text |
Abstract :In present work forward osmosis (FO) process was used as a novel process for the
removal of Cd+2 ions from wastewater. Cellulose acetate (CA) membrane used as flat
sheet membrane for Cd+2 ions removal. MgSO4.7H2O with different concentration was
used as draw solution. Influence of different parameters was studied such as
concentration of draw solutions ranged (10-150 g/l), concentration of feed solutions
(10-200 mg/l), flow rate of draw solutions (30-100 l/hr), flow rate of feed solutions (30-
100 l/hr), and temperature of both feed and draw solution (10-40oC) at constant
pressure 0.3 bar gauge. The results proved that when the draw solution concentration,
flow rate of feed solution, and temperature of both feed solution and draw solution
increased, the water flux increase. Water flux decreased by increasing cadmium ions
concentration in feed solution, operating time of experiment, and flow rate of draw
solution. Cadmium ions concentration in feed solution effluent increased when
concentration of feed solution increased, time of experimental work, draw solution
concentration, feed solution flow rate, and temperature of feed and draw solutions and
decreased with increasing draw solution flow rate. According to the results obtained,
forward osmosis process can be used to recover Cd+2 ions contaminated wastewater
with removal efficiency 78.87% after 3 hrs. Reverse salt flux of MgSO4.7H2O through
the CA membrane decreased with time which reached 23.34 g/m2

Abstract | Full Text |
Abstract :The ultimate capacities of single piles utilized in ten projects in Basra-Iraq are
evaluated using: various interpretations of pile load test results; several static
methods based on site investigation programs; and the finite element method via
(PLAXIS-3D).For the well-behaved tests, it is realized that the load-settlement data
can be best fitted by a hyperbola. Accordingly, Rollberg method well-harmonizes the
test results and allows various interpretation methods to be applied on the
extrapolated curves. It is found that, the static methods spread over a wide range of
values. Finite element analyses exhibited good agreement to the measured values. It
produces failure loads, almost, similar to that obtained from Rollberg method. The
finite element analyses revealed local settlement of (0.6% - 1.8%) of the pile diameter

THE THEATRICAL PERFORMANCE IN THE CINEMATIC MOVIES |
Author : Dr. Sarmad Saleem Abbas |
Abstract | Full Text |
Abstract :The beginning of the art of acting in cinema depends on the technical development
of the industry. Cinema began to present silent films because of the lack of technical
means for recording sound at the time. The actors expressive role in performing the
dramatic character he represents in the film depends mainly on his physical abilities
the embodiment of emotions in all situations that pass through the personality of the
cinematic film. Many academic studies have compared and searched for differences in
the performance of the theater and film actor. A study did not address the cinematic
performance of a theater actor. The performance of the actor through the screen is also
a feature of the cinematic performance of the scene. The combination of expressive
techniques used by the audiovisual arts in a presentation designed to convey an idea to
the recipient through the integration of artistic elements into a form of artistic creativity
that has unity and aesthetic harmony must include the performance of the actor in the
presentation. Therefore, studies and research should be conducted to identify this
representative performance in the presentation.

IMPACT OF CAVITATION WITHIN THE HOMOGENOUS SOIL UNDER HYDRAULIC STRUCTURE ON FORMULATION OF THE SEEPAGE QUANTITY AND UPLIFT PRESSURE |
Author : Jaafar S.Maatooq and Dhurgham M.Abdulhasan |
Abstract | Full Text |
Abstract :This study aims to investigate the effect of single cavity when it presence at a
specific location within the homogenous soil, on the behavior of seepage and uplift
pressure under a hydraulic structure. The results are analyzed to introduce
deterministic formulae for calculating the amount of seepage and the uplift pressure
head. The work was done in three stages by using experimental investigation; the first
stage includes 36 models of 75mm in diameter cavity, while the second and the third
stages includes eight models for each with 100mm and 34mm diameter of cavity,
respectively. The results shows that, when the cavity presence at the left side its impact
was positive on the seepage behavior. While the influence was changed to a negative
impact when the cavity presence at the right side, except at some specific locations. The
statistical software has been employed to generate the two deterministic formulae, and
the results of multiple regressions are checked by statistical indices for the purpose of
recognizing the reliability of the proposed formulae. |

Author : Sri Avijit Majumdar, Dr. A.K. Nayak and Dr. S.N. Misra |
Abstract | Full Text |
Abstract :The urban population of India was 37.11crs as per the Census count of 2011
showing a decadal growth of 31.82% in comparison to the on 12.3% and 17.7%
growth in rural population and overall population respectively (Planning
Commission, 2014). The maximum growth in population has been witnessed in class I
cities. Bhubaneswar is a Class-I as well as the largest and the most populous city of
Odisha. During the period 2001-11 the density of population in the city has increased
at a rapid pace of 24.86% to 3553 persons per sq km. Apart from natural growth
,rural urban migration to the city is being influenced by better infrastructure like
schools and colleges, hospitals, housing, roads, electricity, water supply, drainage
etc. All the above mentioned factors are simultaneously witnessing pressure due to
rising number of users. Water supply and organized drainage system are vital
components for any human settlement. Lack of quality water supply and poor
drainage and sewerage system can lead to multiple health hazards. An estimate puts
that globally 2.5 billion people do not have access to safe drinking water and
improved sanitation facilities (UNICEF /WHO, 2009). The above situation calls for
an urgent attention of the urban planners in our country to make adequate provision for safe drinking water supply along with improved drainage and sanitation to ensure
the well-being of its inhabitants. |

ENTREPRENEURIAL ECOSYSTEM MATRIX (EEM): A PROPOSED FRAMEWORK FOR NIGERIAN UNIVERSITIES TO BECOME FACTORIES FOR STARTUP COMPANIES |
Author : Stephen OLUWATOBI, Damilare OSHOKOYA, Efosa UWOGHIREN, Adeola OYEBODE and Colette NSOFOR |
Abstract | Full Text |
Abstract :Universities have been identified as knowledge creation centres, where knowledge
can be created and transferred for social and economic benefits and advancement.
What makes them relevant now is that we are in the knowledge era where knowledge
has become the currency for facilitating sustainable development; hence, the role of
universities, as knowledge creation centres, has become more relevant. This relevance
is reflected in their potential to generate ideas and knowledge that can become products
and companies when harnessed. The gap, however, has been that a lot of the knowledge
created by universities has not gone beyond the idea or prototype stage. This study,
thus, proposes a framework to harness knowledge created in and by universities to take
them from the concept stage to the product stage and then to the startup stage, hence,
making them factories for startup companies. This is essential for harnessing the commercial value of knowledge. This study, therefore, presents a structure on how
Nigerian universities can become factories for shipping startup companies that create
value, opportunities and wealth, through their entrepreneurial efforts. |

STATISTICAL OPTIMIZATION AND SENSITIVITY ANALYSIS OF RHEOLOGICAL MODELS USING CASSAVA STARCH |
Author : M. E. Ojewumi, G.O. Kayode, J. A. Omoleye and D. T. Oyekunle |
Abstract | Full Text |
Abstract :Models are sometimes employed to determine some parameters that can be used to
distinguish between different types of food samples. Rheological models can be used to
predict flow for severe conditions where it is difficult to determine the nature of the
fluid flow, consequently it is essential to select the appropriate rheological models. This
study aims to propose a rheological model that describes an ideal cassava starch
rheological behavior and its influence on state variables such as concentration and
temperature in order to validate the rheological models. In this study, five rheological
models (namely; Power-law model, Robertson-stiff model, Herschel-Bulkey model,
Prandtl-Eyring model and Bigham plastic model) were amended into various statistical
model by adding the error variance (e). This study concludes that Herschel-Bulkley
model and Robertson-stiff model closely explain the rheological patterns occurring
during the production of cassava starch. The sensitivity evaluation of other rheological
models demonstrate that the validity of Power-law model, Herschel-Bulkley model and
Robertson stiff model is not notably influenced by changes in concentration and
temperature of the cassava starch. Nevertheless, the Prandtl-Eyring and Bingham
plastic models are noted to have less reliable prediction at lower temperature and
higher concentration respectively. |

DESIGN SOLUTIONS CREATING BARRIERS TO ACHIEVING UNIVERSAL DESIGN COMPLIANCE OF ACADEMIC BUILDINGS IN UNIVERSITIES IN NIGERIA |
Author : A. B. Sholanke, A. B. Adeboye and O. A. Alagbe |
Abstract | Full Text |
Abstract :The concept of universal design is a design ideology that targets accommodating
the accessibility and usability needs of everyone regardless of their ability or disability.
It is however observed that in Nigeria, some educational facilities and environments
are to some extent inaccessible to the mobility impaired. This is as a result of avoidable
design solutions that are inadequate to meet the needs of all potential users. Where
educational facilities are inaccessible or difficult to reach for any user group, such
situation is capable of depriving those affected, the opportunity of acquiring the
education needed to advance in life. To this end, this study investigated design and
construction solutions that constitute barriers to achieving universal design
compliance of academic buildings in universities in Nigeria, with a view to finding ways
of improving accessibility to such buildings and their facilities for users, regardless of
their mobility status. The study was a multiple case study research that adopted
qualitative research approaches to collect, analyze and present data. The result showed
that the areas that constitute barriers to achieving universal design in the academic
buildings range from lack of equitable accessibility provisions, inappropriate access
provisions, nonflexible usability provisions among others. This indicates that for the
academic buildings to be able to adequately meet the accessibility and usability needs
of all category of users, there is a need to eliminate the identified designed barriers
preventing universal design compliance in them by retrofitting the structures with
inclusive design features. To this end, some recommendations which includes, carrying
out a phased renovation of the existing academic buildings, as well advising the
management of universities in Nigeria to ascertain that subsequent routine and
periodic maintenance works in their institutions comply with UD parameters before
implementation, were made. |

RELATIONSHIP BETWEEN BOD/COD RATIO AND OCTANOL/WATER PARTITION COEFFICIENT FOR GLUCOSE, LACTOSE, SUCROSE, FORMALDEHYDE, ACETIC ACID AND OXALIC ACID |
Author : Latifa Mirzatika Al-Rosyid and Sarwoko Mangkoedihardjo |
Abstract | Full Text |
Abstract :The purpose of this study was to obtain a relationship between the ratio of
BOD/COD and partition coefficient octanol/water (Pow) for glucose, lactose, sucrose,
formaldehyde, acetic acid and oxalic acid. This relationship was supported by the
toxicity test of each organic material on fish. The results show that the lower the
BOD/COD ratio, the higher the Pow coefficient, which means more organic matter
leads to biomass. Among the organic materials studied, formaldehyde has the lowest
BOD/COD ratio (<0.1) and highest Pow (>4) and was supported by the results of its
toxicity in fish having the lowest LC-50 (24 mg/L). Whereas lactose has the highest
BOD/COD ratio (>0.9) and lowest Pow (<0.7) with the highest LC-50 (851 mg/L). The
rest of the organic substances have characteristics in the range of lactose and
formaldehyde |

Author : Tatyana Barsukova, Valentina Ivashova, Julia Gunko, Oksana Gavrilova, Anastasia Chaplitskaya |
Abstract | Full Text |
Abstract :The main idea of designing professional competence of the regional agrarian elite
is to provide the leaders of the student community with the opportunity of active social
practice of making management decisions, developing social responsibility and
striving for continuous excellence through participation in the development of the
management decisions based on customer feedback. To organize systematic social
practices involving student leaders, who will be the regional agrarian elite in the
future; it is necessary to accumulate the work of the university to provide feedback to
students in the relevant structural units of the university and student assets engaged in
work to ensure the quality of education. The implementation of such idea will allow
the formation of institutional mechanisms: a regulatory framework, documented
procedures, algorithms of information exchanges of stakeholders for the development
and adoption of effective decisions, which are generally aimed at ensuring the
professional competence of the regional agrarian elite |

Abstract | Full Text |
Abstract :The purpose of this study is to know the sociology of farming farmer’s cassava in
Muting District. Research needs to be done because by knowing the pattern and life
expectancy of the community at the village level can be the basis for the preparation
of planning action of tapioca flour factory development in Merauke. The type of
research is field survey research using the method of data acquisition purposive
sampling. Results of field data and information indicate that the community in Muting
District consists of local and non-local communities. Most people have livelihoods as
farmers. Agricultural system applied that is agriculture traditional. Local people for their daily life have livelihoods from hunting, fishing and farming in the garden or
yard. The results of hunting, fishing, and cultivation are used for family consumption
needs, but if there is a new residue will be sold to the home environment. While nonlocal farmers have the main livelihood as fruit farmers other than currently farmers
working in oil palm plantations that operate the Muting area. Farmers in Muting
cultivate cassava in small areas, cassava is only cultivated in the yard and more in
family consumption and the largest land area of 1 ha. With 1 ha of planting area,
farmers are still experiencing marketing constraints. The marketing constraints of
cassava ie the distance to the market center is very far and the cost of transportation
is high. If marketed to Muting and the surrounding environment, the low purchasing
power of people, because the people in general have a cassava plant even in the yard
and was quite consumed by the family. Cassava consumption by the community in
Merauke is not a staple food but only as a side food and food diversification efforts
are still very low. |

Author : Weam Abdulwahhab Mohammed, Mustafa Hussein Abed ALDulaimi and Thair Jabbar Mizhir Alfatlawi |
Abstract | Full Text |
Abstract :The rapid drawdown effects directly on the stability of upstream slope of earth
dams, where the seepage direction will be in the reverse direction due to emergency
emptiness, which causes flow from downstream to upstream through the dam body,
such flow may be not considered in design. In this research two cases of rapid
drawdown are adopted, in the first case, the reservoir is empty from service canal
(outlet flow) where the discharge of this canal is 200 m3
/sec. In the second case, the
reservoir is empty by spillway canal with discharge capacity equal to 2750 m3/sec.
The results show that the discharge from spillway takes a few hours which threaten
the dam stability compering with allowable factor of safety while discharge from
outlet flow service takes a few days and the threaten was nominal, both of them under
rapid drawdown condition . |

ASSESSMENT OF THE PROCESSES OF FORMATION AND TRANSFER OF DUST FROM OVERBURDEN DUMPS IN THE ALEKSEEVSKY QUARRY OF BUILDING MATERIALS |
Author : A.A. Yamashkin, M.A. Zhulina |
Abstract | Full Text |
Abstract :A methodology for assessing the processes of dust formation and transfer from the
external dumps of overburden rocks, formed near the Alekseevsky quarry of building
materials in the Republic of Mordovia, was proposed in the Article. The basic element
of this assessment is in consideration the physical-geographical characteristics of the
quarry area, including basic meteorological characteristics and coefficients
determining the dispersion conditions of pollutants, combined with an analysis of the
geometric characteristics of the dump and the properties of the dump rocks. The
proposed method includes the use of sieve analysis of dusting material soaring in the
air, as well as computer simulation using the “Ecolog” software package. It was
established, investigated dusty material is largely composed of particles that are a
subtype of microscopic dust, 0.4 mm in size. Spherical particles and irregular
polyhedrons are the predominant. This form is primarily associated with the genesis
and structure of overburden and host rocks of sedimentary origin. As a result of the
sieve analysis, the spatial patterns of dusting material distribution, blown off from the
dump, were established. When moving away from the overburden dump, large
particles from the dust flow quickly precipitate. Already at a distance of 10 m, the
number of particles larger than 1.6 mm decreases sharply, and at a distance of 50 m
particles larger than 0.63 mm make about 5% in a dust flow. The bulk of dust
particles have a size of less than 0.14 mm at a distance of more than 70 m. As a result
of the application of the “Ecologist” software complex, a prognostic map of inorganic
dust dispersion from overburden dumps in the summer was built, considering that
another similar dump was being formed simultaneously with the existing dump, which
has practically exhausted the possibility of overburden accumulation. As
recommendations for reducing dust emission from existing and projected dumps, it
was proposed to fix their surfaces with a biogenic or chemical protective layer.

EVALUATION OF AGROTECHNICAL EFFECTIVENESS OF BIOHUMUS OBTAINED DURING THE PROCESSING OF DEFECATE AND BEET PULP |
Author : M.A. Zhulina, N.N. Stultseva |
Abstract | Full Text |
Abstract :A method for processing the waste of sugar production - defecate and beet pulp -
into highly effective biohumus fertilizer was proposed in the Article. The defecate, dry
pulp and spent litter straw were mixed at a ratio of 2:1:1 by volume, and periodically
moisturized to a moisture level of 70%. After that, representatives of the derived
subspecies of earthworms Eisenia foetida were added into the substrate, according to
the standards 10-12 pcs. on 1 l of mix. Laboratory analysis of the physico-chemical
properties of the defecate, beet pulp and biohumus found that the organic fertilizer
obtained according to the proposed scheme has a close to neutral acidity, and the
ratio of humic acids to fulvic acids is close to optimal. The remaining agrochemical
indicators also make it possible to consider the resulting biohumus to comply with all
the necessary norms of this type of fertilizer. To evaluate the agrotechnical
effectiveness of biohumus, an experimental method was proposed and tested on an
experimental site with sod-podzolic soil. The soil section and agrochemical
characteristics of investigated soil profile were given in the article. Control soil
without any fertilizer, pork manure, rotted chicken dung, peat and biohumus are
offered as investigated soils. As a result of the experiment on the evaluation of
agrotechnical effectiveness of biohumus obtained, it was found that the maximum
growth of humus content of sod-podzolic soil was achieved with the introduction of
biohumus - 30.6%, while the coefficient of humification was 0.21. The bioeffectiveness
assessment experiment established that biohumus prepared on the basis of defecate,
beet pulp and litter straw has a positive effect on Domodedovsky potato varieties. The
number of tubers and their weight increased, and the yield increased by 30-40%
relative to the control plot without fertilizer |

Author : Satriani Said Akhmad, Muhammad Tola, Wihardi Tjaronge, Rudy Djamaluddin |
Abstract | Full Text |
Abstract :The fire protection system generally uses a sprinkler, the sprinkler head / head will
break and the water radiates in all directions to extinguish the fire but also damages
electronic equipment, this research can minimize damage by designing sprinklers that
direct water spray in certain areas detected by the sensor. Integrating fire protection
systems with electrical installation systems to prevent fires. Build a web-based
intelligent information system that is integrated between fire protection systems and
electrical installation systems. The research method has 4 stages, namely stage I,
preparation of all the tools and materials needed, making a controlled sprinkler
prototype directing the spray. Perform testing until this system works properly. Phase
II, the making of an electrical installation panel that has been connected to a
sprinkler, creates a system that is integrated through the web site between the fire
protection system and the buildings electrical installation system. Stage III, testing
equipment until it is successful. Stage IV, making research reports into a dissertation,
publishing in national and international journals. From this research, a prototype
sprinkler system has succeeded in directing the jet of water directly to the hotspot. The
system simulation works at the maximum distance according to the effective sprinkler
beam which is 90 cm. The blackout time depends on the position of the fire in the
sprinkler range. The fire point located on the scanning path farthest from the starting
point requires a relatively longer blackout time than the hotspot near the starting
point of scanning. Intelligent sprinkler systems and electrical installation systems have
been integrated through the web service. |

Abstract | Full Text |
Abstract :The purpose of this paper is to critically review the papers published in the area of
infrastructure design, environmental design, construction of houses, and crime and
built environment. The paper aims to critically evaluate the available evidence on the
contribution of crime prevention through environmental design as a crime prevention
strategy (design modification or hard control using better and developed
infrastructure). Design methodology– structured literature review approach is
adopted to analyze the previously published papers. Findings – The review concludes
that there is a growing body of research that supports the assertion that CPTED is
effective in reducing both crime and fear of crime in the community. The findings also
conclude that only very little amount of work has been done in the area of crime
against women/women’s fear of crime and built environment. Research
limitations/implications – Although the paper may not review all the evaluations of
CPTED, it nonetheless provides a detailed compilation and overview of the most
significant research in the area using a structured literature review. Practical
implications – CPTED is an increasingly fashionable approach and is being
implemented on a global scale. |

KOLA-NUT TRANSPORTATION IN NIGERIA: A CASE STUDY OF REMO-LAND, OGUN STATE |
Author : Ruddy Harjanto, Subandiyah Azis and Sutanto Hidayat |
Abstract | Full Text |
Abstract :Transportation is a crucial factor in improving agricultural productivity. It
enhances the quality of life of the people, creates a market for agricultural produce,
facilitates interaction among geographical and economic regions and opened up new
areas to economic focus. The link between the farmers and consumers is enhanced by
efficient transport mechanism for constant inflow of farm produce. The economic
investigation into how this process is undertaken is necessary for the profitability of
any business venture. This research investigates the crucial role transportation plays
in kola nut production using survey research technique. A total of 100 respondents were
randomly selected and interviewed using well-structured questionnaires. This
represents 20% of the registered kola nut farmers in Remo land, Ogun state. Sagamu
Local Government Area has 40% of the respondents while 30% each were from Ikenne
and Remo North Local Government Areas. The obtained data were analysed using
descriptive statistics. This study revealed that an improved transportation will
encourage farmers to produce more, add value to their produce, and reduce spoilage and wastage. Efficient transport helps to move inputs and workers to and fro the farm
as well as products to markets and agro-allied industries. Adequate transportation have
positive impact on farmers’ productivity, income, employment and poverty reduction in
the rural areas |

Author : K.Marimuthu, and S. Kothandaraman |
Abstract | Full Text |
Abstract :The awareness on seismic design for reinforced cement concrete (RCC) beamcolumn (BC) joint was started with publication of ACI-ASCE 352 report in 1976. In
past earthquakes, several RCC buildings were suffered by severe damages/collapses.
These failures were occurred due to the usage of poor detailing in joint and insufficient
anchorage of beam longitudinal bars. The research on the BC joint was started in 1967
and extensive research has been carried out on studying the behaviour of RCC joints
under seismic condition through experimental and analytical studies. There are
different methods of reinforcing techniques have been developed over the years and
their main aim was to determine the effective reinforcing technique for beam-column
joint which include easy to adopt, effective performance, economical and cost-effective.
This paper gives an overview of the use of different reinforcing techniques used in
beam-column joint so far. The objective of this paper is to critically review the different
techniques developed so far with reference to the effect of each technique and outlined
the salient features of each technique.

MECHANICAL PROPERTIES OF INDONESIAN RUBBER FOR LOW-COST BASE ISOLATION |
Author : Bernard Thredy William Wijaya, Tavio |
Abstract | Full Text |
Abstract :From the earthquake histories in Indonesia, it was shown that the most damaged
buildings was residential houses. The main issues of the poor seismic performance of
the residential houses was due to poor detailing and low quality of construction
materials. To be able to reduce seismic hazard potential for residential houses, there
was a need to implement a low cost earthquake friendly system namely the low cost
base isolation.Low cost base isolation is specifically designed for the residential house
usage, using local Indonesian rubber and fiber reinforcement. In this paper three
types of Indonesian rubber will be tested, namely RB 35, RB 70 and RB 90. The results
shows that supposedly harder RB 70 Modulus was only higher at low strain level, but
having lower Modulus at high strain level. It was also shown the hardest RB 90
having pretty low elongation before it breaks, making it risky touse for base isolator.
The overall results shows that the RB 35 having highest elongation before it breaks
and moderate Modulus is the most suitable for the low cost base isolation usage |

DEVELOPMENT OF EFFICIENCY BASED STANDARDS FOR OPTIMUM DESIGN OF STIFFENED PLATE GIRDERS |
Author : Priya A Jacob, Justin S, R Mercy Shanthi |
Abstract | Full Text |
Abstract :In recent years, stiffened plate girders have been used extensively for long spans
due to its high flexural rigidity and buckling resistance. While designing, the amount
of costly steel used in a girder can be reduced by adopting optimum dimensions for
web depth, web thickness, flange thickness, flange breadth and spacing of stiffeners.
Such design can finally result in an economical design. Indian standards have code
provisions which can be used for design of stiffened plate girders. However, relatively
little attention has been devoted to developing efficiency based standards in the design
of plate girders. These efficiency based standards in the form of design charts can
help a designer in the economical design of stiffened plate girders considering
strength and serviceability conditions. Herein, relationships between the design
variables are developed using genetic algorithm (GA) based optimization formulation.
Both transversely stiffened and corrugated web plate girders are considered. The
relationships are further used to develop design charts which can be useful for design
engineers. The design charts are developed considering strength and serviceability
conditions as specified by the IS 800:2007.

STRENGTH AND DUCTILITY BEHAVIOUR OF CONCRETE COLUMNS UNDER COMPRESSION WITH DOUBLE LAYERED STIRRUPS: AN EXPERIMENTAL STUDY |
Author : Mahesh Kumar, S. Kaleem A. Zaidi, S. C. Jain, K. V. S. M. Krishna |
Abstract | Full Text |
Abstract :The strength and ductility of concrete ameliorated by providing appropriate
confinement has paved way for designing structures that would withstand loads of
extreme intensities. The behaviour of concrete confined by single layered transverse
reinforcement has already been construed substantially. This paper presents a
consistent experimental study conducted on a novel and recently proposed Reinforced
Concrete column consisting of two layers of confining reinforcement. The concrete
inside the column experiences three different levels of confinement, viz., doubly
confined concrete inside the inner layer of lateral reinforcement, singly confined
concrete between the two layers of the transverse reinforcement, and the unconfined
concrete cover. The variables contemplated to study the behaviour and amount of
confinement in double layered stirrup concrete column comprise: addition of inner
layer, variedness in the shape and form of the transverse reinforcement forming the
inner layer, grade of concrete, varying number and amount of longitudinal
reinforcement forming the outer layer, proximity ratio between the inner and outer
layers and the varied amount and spacing of transverse reinforcement encompassing
the inner layer. It has been ascertained that the confinement effects emerged from the use of single layered stirrup transverse reinforcement were deficient when compared
to that of double layered stirrup transverse reinforcement. Aside from enhanced
strength and ductility, this novel structural form of concrete column exhibited an
added advantage in terms of ease of construction over conventional single layered
stirrup column. |

Abstract | Full Text |
Abstract :Machining is one of the unavoidable operation after the processing of any type of
material. Because of the advancement in the technology and innovation in the materials
area, the composite materials are replacing and occupying the traditional materials
market rapidly. Among these composite materials, the Fiber Reinforced Polymer (FRP)
composite materials are found to be technically and structurally competitive and are
widely used in a number of engineering industrial applications. The machining of these
composites is found to be a complex phenomenon due to the influence of a number of
machining and material parameters related to machining. Since drilling is the most
frequently applied machining operation on composites, many research works were done
on the drilling of composites, which resulted in numerous parameters that have influence
on the drilling operation, impact on work material and cutting tool damage, cost of
machining, material removal rate etc. So, at the background, it was thought to have a
review on the issues related to drilling on the composite materials, which could help the
manufacturing sectors and researchers in order to enhance the productivity. Thus the aim
of this technical paper is to provide a detailed study of various issues related to drilling
of FRP composite materials. This paper also comprehensively addresses the success and
the failures of drilling operations, the factors associated with the drilling operation, their
impact on the various output parameters. In addition, this review paper also discusses
about the influences of a number of machining parameters and their influence on
machining. |

Author : M.Vinay Kumar and U.Salma |
Abstract | Full Text |
Abstract :This paper presents modelling and control of maximum power point tracking
(MPPT) for a three phase grid–tied photovoltaic (PV) system by using a non-linear
controller namely double integrated sliding mode controller (DISMC) to enhance
MPPT and to stabilize the output power of PV system. The non-linear I-V, P-V
characteristics of PV systems depends upon irradiation and temperature; causes
difficulty in tracking maximum power. The PV system consists of a PV panel, DC/DC
boost converter and a MPPT controller to generate pulses which are fed to converter
for tracking maximum power. In this paper, the performance of DISMC-MPPT shown
to be effective when compared to other controllers like perturb & observe (P&O)-
MPPT, adaptive P&O-MPPT, sliding mode controller (SMC)-MPPT and integral
SMC (ISMC)-MPPT. The presented DISMC-MPPT method is robust, provides quicker
and steady tracking maximum power with respect to the other discussed methods and
also performs well during any change in weather conditions. To validate the
effectiveness, the mathematical modelling of all the above mentioned non-linear
controller MPPT methods and their simulations are carried on Matlab/SIMULINK

Abstract | Full Text |
Abstract :The wireless telecommunication system of hybrid free-space optics (FSO) utilizes
a transmission medium of free space to transmit data at high bit rates. However, it is
exposed to various effects of noise in different weather conditions. This paper
investigates on compensation for atmospheric turbulence in optical communication
systems of 10-channels spatial division multiplexing (SDM) over FSO link under
different weather conditions based on linear Gaussian filter (LGF). The performance
of a 10-channel transceiver system is evaluated in an SDM-FSO link under the clear
sky, haze, and rain weather conditions based on Gaussian filter at the receiver.
Furthermore, the simulated system has transmitted 100 Gbit/s up for a distance of 12
km FSO in superbly very clear weather condition. Moreover, it is also transmitted 100
Gbit/s up for a distance of 4.2 km FSO during heavy rain and up to 1.1 km distance FSO during heavy haze. The results show that system capacity is effectively increased
with the use of SDM that operate at 1550 nm wavelength. Finally, the validation is
conducted based on analyzing eye diagrams, Q-Factor and Bit Error Rates |

Author : Harith Yarub Maan |
Abstract | Full Text |
Abstract :The present work aims to investigate the distribution of strains in incremental sheet
metal forming process using different geometries. Four shapes were used to develop the
strain paths: truncated cone, pyramid, dome, and circular generatrix are formed in
incremental sheet forming process. The difference in strain paths depends on the
difference in the geometric shapes of the formed parts. Circle grid analysis was used to
obtain strain paths along the parts. Strains distribution was evaluated by circular grid
system (CGS) where a pattern of a small circle was electrochemically etched on the sheet.
The sheet is deformed during forming and the deformation of the circle is measured and
analyzed to explore the behavior of strains distribution in incremental sheet metal
forming. The curvature of the part is a large or plane wall the strain mode is plane strain

Author : R, S. E.A. Pérez Frye R, J.F. Llano M and D.A. Zuleta D |
Abstract | Full Text |
Abstract :Steels for machine manufacturing can be hardened through thermal treatments. In the
quenching treatment is possible to use different substances to improve mechanical
properties, in particular hardness and probably the wear resistance. As quenching media,
the water, water and salt solutions, polymer solutions, vegetable oils and mineral oils are
commonly used. In this work, vegetable oils (vegetable blended, soybean, canola and
sunflower) and mineral oil (10W30) were used as an alternative of quenching media to
study the performance of the hardness and the microstructures obtained. The quenching
treatment was carried out involving heating at temperature of 850º C and keeping inside
electric furnace for 50 minutes to achieve homogeneity in the internal structure. The
quenched was carried out at room temperature using each vegetable and mineral oils.
The results showed that use of vegetable oils is a good alternative as a tempering
substance. The results showed that vegetable oils have a better performance than mineral
oil, as they allow to reach hardness above 40 HRC and generate high strength and
toughness microstructures. Among vegetable oils, Canola oil allowed the highest

Author : Irina Ilina, Elena Streltsova, Alex Borodin and Irina Yakovenko |
Abstract | Full Text |
Abstract :The problem of managing the R&D sector sustainability in Russia is of particular
relevance in terms of scaling external and internal challenges faced by the country. Such
challenges require an even greater intensification of the efforts to solve the problems
accumulated in Russian economy and innovation system and associated with the state
transition to new technological way. A key criterion of R&D sector competitive
sustainability is the creation of practice-oriented and relevant results of intellectual
activity. Correlation analysis of innovative activity indicators in developed countries over
the 2007-2015 revealed a pattern of two-fold excess of export licenses over the amount of
public investment in science. This dependence is crucial in the study of competitive
sustainability within R&D sector. The method of assessing the efficiency of public
spending on R&D, including an analysis of the dynamics of the growth rate of
performance indicators and their financing in case of R&D completed in the period is
proposed as the main management tool of R&D sector competitive sustainability |

Author : Ikpotokin I., Uguru-Okorie D. C. Osueke C. O., A. A. Dare and M. O. Petinrin |
Abstract | Full Text |
Abstract :An investigation was carried out on the effect of the use of a parabolic baffle at
different baffle cuts on the performance of shell and tube heat exchangers. The
numerical study was performed on a personal computer with 12 GB RAM and Intel®
Core™ i7 2.50GHz CPU using a CFD software Comsol Multiphysics. The modeled
heat exchanger had 37 tubes, shell internal diameter of 200 mm, 6 baffles with baffle
spacing of 100 mm. The results from the effect of mass flow rate and baffle cut on heat
transfer rate and pressure drop in the shell side of the heat exchanger were compared
with the circular segmental baffle cut of 25% and that of the parabolic baffle cut of 25
and 30% of the inner shell diameter. At 25% of the shell diameter baffle cut, the
parabolic cut had an improved heat transfer rate compared to that with the circular
segmental baffle cut with a drawback of higher pressure drop. As the parabolic baffle
cuts increased, there was a decrease in heat transfer rates and pressure drops at the
various mass flow rates considered. At 30% of shell diameter cut, the performance of
the parabolic segmental baffle cut gave results similar to the circular segmental baffle
cut at 25% of the inner shell diameter. The investigation showed that for a parabolic
baffle cut, 30% of the shell diameter is recommended for optimum performance. |

Abstract | Full Text |
Abstract :This article evaluates particle board using corncob (CC) particles and mixing it
homogeneously in varying percentages 20%, 40%, 50%, 60% and 80% with sugarcane
bagasse (SB) using Urea Formaldehyde resin as adhesive. Particleboards of 100% SB
and 100% CC were also made, thereby making seven different compositions. Properties
of particleboards produced such as density, water absorption, thickness swelling,
modulus of rupture and modulus of elasticity were investigated. The densities of
particleboards ranged from 400 Kg/m3
to 620 Kg/m3
. The results of the tests also show
that the particleboard with 50% CC and 50% SB using equal volume of adhesive had
favorable physical properties that are recommendable for indoor uses in buildings. In
contrast, the panels cannot be recommended for load bearing purposes because they
exhibit poor mechanical properties, but these mechanical properties tend to improve as
the composition of CC increased from 40% to 100%. The MOR and MOE results obtained
in this research work lead to a conclusion that the mechanical properties of the panels
were improved as the percentage of CC replacement increased but possessed poor
physical properties. Within the experimental investigation and possible limitations, the panels with 50% CC and 50% SB are the most preferred since they had preferable
performance for both physical and mechanical properties. |

Abstract :In this investigation, Cashew nut shell liquid (CNSL) biodiesel, hydrogen and
ethanol (BHE) mixtures remained verified in a single cylinder direct-injection diesel
engine to examine the recital plus discharge features of the engine. The engine stayed
verified at supreme force and rapidity of 1500 rpm. The ethanol remained
supplemented 5%, 10% and 15% correspondingly through enhanced CNSL as well as
hydrogen functioned twin fuel engine. The consequences designate that while
associated through well-ordered diesel and biodiesel-hydrogen process, the recital
and discharge features of ethanol mixtures obligates upgraded. The brake thermal
efficiency upsurges somewhat through 10% ethanol mixtures and nope noteworthy
enhancement by advanced ethanol mixtures. The exhaust gas temperature and NOx
release augmented by 10% ethanol accumulation. Through greater proportion of
ethanol in the biodiesel hydrogen (BH) mixtures the HC, CO releases might upsurge.
However the routine of 10% ethanol might diminish the HC and CO releases
equally. Overall the BHE mixtures ensure greater NOx discharges, associated by
biodiesel and diesel energy. Throughout the BHE mixtures offers lesser HC, CO, as
well as greater NOx release associated through the well-ordered diesel fuel.
Nevertheless the embellishments of added ethanol thru BH mixtures require no
substantial enhancement in the recital discharge and stages |

Author : Anusha Peyyala and Dr N V V S Sudheer |
Abstract | Full Text |
Abstract :In this project, experimentation is done on Vapour Compression Refrigeration System
[VCRS] as the COP is high for this system and it is the present trend of the HVAC in the
domestic industry. This study presents investigation of best suited refrigerant and
insulation combination for gas pipeline and liquid pipeline of a split air conditioning
system. Analysis are performed for R22-Chlorodiflouromethane, a HydroChloroFlouro
Carbon refrigerant, which has been using in the present world that cause both global
warming and ozone layer depletion and R410a, mixture of di-flouromethane and
pentaflouroethane, a Hydroflouro carbon refrigerant, which is future of HVAC which
reduces the effect of ozone layer depletion [ODP] and Global Warming Potential
[GWP].For these two refrigerants, we had found out the best insulation suitable as
insulation also affects the COP of air conditioner, which has been observed from the
literature. Minimizing the temperature of refrigerant in suction line helps condensing unit
work more effectively intern the system performance increases. This reduces the overall
power required for working of air conditioner, thereby reducing the maintenance cost of
system. Also, it helps the manufacturer to provide best type of insulation for the system at
reduced cost thereby reducing overall cost of VCRS.To perform the experimental
comparison, 16 tests were carried out for 5 times with each refrigerant Insulation
combination. From analysis it is observed that, COPA for NRF+AF gives highest value
for R22 and R410awhen compared to various insulation materials. Power required for
VCRS is greater while using R410a than R22. So In this work the main energy parameters
such as COP and work required for compressor are analysed and discussed.

INFLUENCE OF AUSTENITE AND FERRITE STABILIZERS ON THE MICROSTRUCTURE AND RELATED MECHANICAL PROPERTIES OF CARBURIZED STEELS |
Author : Sathyashankara Sharma, Pavan Hiremath, Gowrishankar M C and Manjunath Shettar |
Abstract | Full Text |
Abstract :Carburization is a thermo-chemical treatment generally employed to enhance the
surface (wear) properties of low carbon steels. The recent carburization studies also
focus considerable positive impact on bulk properties like tensile strength and
toughness. In view of these observations, the present study focuses on mechanical
properties and microstructure of carburized steels. Accordingly, the commercially
available three types of case hardenable steels like plain carbon (EN 3), alloy steels
with only ferrite stabilizer (20MnCr5) and with both ferrite (Cr) and austenite (Ni)
stabilizers (EN 353) were initially normalized to standardize the room temperature
structure before carburizing and machined to ASTM standards to prepare the
specimens. The machined specimens were gas carburized using carburizing furnace
for 2.5 mm case depth and furnace cooled. Tensile and hardness tests were conducted
before and after carburization. The plain carbon steel displayed slight reduction in
tensile strength and the steels with alloying elements increased the tensile strength
considerably. It was also found that Ni and Cr restrict the grain growth and increase
the strength of steel even in furnace cooled condition. Microstructure analysis of
carburized steels revealed markable impact on the type and distribution of room
temperature phases. The carbon content in the case was nearly 0.8 wt. % after
carburization and hardness increase in the surface ranges from 130 to 170% as that
of its original hardness. The combined effect of Ni and Cr also improves
hardenability.

Abstract | Full Text |
Abstract :This study was conducted to review the effect that simulation training programs
for emergency situations involving newborn babies have on nursing students’ clinical
performance. Opportunities for nursing students to clinically practice what they
learned are on the decrease. Even if they take part in practice, they are usually
limited to simple tasks or observation. Given this reality, there is an urgent need to
develop new measures to improve their clinical practice ability. The low fertility rate
that is worsening over time and the difficulty in operating an intensive care unit for
newborn babies has led to a decrease in such departments, leading to difficulties
experienced by a number of universities in allocating clinical training venues. After
conducting a survey on the needs regarding training themes in the nursing of newborn
babies, simulation training programs would have to be developed based on themes
where the needs are the highest. |

CONSTRUCTING AN INTELLECTUAL PROSPECT OF VENTURE MANAGEMENT PRACTICES: A DIVIDE BETWEEN INFORMAL AND FORMAL ELECTRONICS ENTREPRENEURSHIP |
Author : Adebanji Ayeni, Fred Peter, Henry Inegbedion, Taiwo Akinyemi, Mistura Sanusi |
Abstract | Full Text |
Abstract :The practice of venture management has recorded success in the United States of
America and India. This brought about the turn-around of businesses, both prospect
and existing formal business operators in these nations. In the case of Nigeria, banks
and other financial institutions have ended up providing advice to successful firms to
acquire business organisation in distress and at times are the leaders in that
particular industry, thus bringing about unemployment. It is of a note that
entrepreneurs are the drivers of a nation’s economy irrespective of government
practices. It is based on this premises that the relevance of transition from informal
to formal entrepreneurship practices must occur for the existence of economic
growth. To bridge this gap in literature, a comparative study on venture management
practices and expected performance for practicing entrepreneurs in the informal and
formal sector is required |

Abstract | Full Text |
Abstract :The article considers an alternative replacement of oil fuel for pyrolysis gas and
biogas, obtained from household and industrial waste in the Republic of Burundi. Studies
have been carried out concerning pyrolysis processing of both peat and solid agricultural
waste from rice, sorghum, peas, beans, corn, as well as studies of the biogas production
process from liquid waste from the palm-oil production mini-plant Kirekura-Muzazi in
Bujumbura. Characteristics of liquid wastewaters from the Kirekura-Muzazi mini-plant
were studied, physical and chemical parameters (pH, Alkalinity, DCO, DBO5, MES,
MVS, total nitrogen, DCO/N, dry matter concentration, and humidity) were obtained. The
composition of biogas produced from a mixture of liquid waste from a plant for palm oil
production, waste slaughterhouse, cow manure and pig manure is given. Also the authors
considered the possibility of reconstructing the diesel-electric generating unit of the
industrial group “Regideso” for biomethane with replacement of diesel fuel, which will
increase the service life of the engine, save diesel fuel, create sources of dual fuel, and
improve the operation of the gas-diesel unit without buying special spare parts.
Directions have been proposed to solve the problem of the shortage of primary energy
sources in the Republic of Burundi, and recycling of city and industrial wastes will also
solve environmental problems. |

NORMALIZED GEOMETRIC INDEX: A SCALE FOR CLASSIFIER SELECTION |
Author : Krishna Sriharsha Gundu and Sundar S |
Abstract | Full Text |
Abstract :For years, the Machine Learning community has focused on developing efficient
algorithms that can produce very accurate classifiers. However, it is often much easier
to find several good classifiers based on dataset combination, instead of single classifier
applied on deferent datasets. The advantages of using classifier dataset combinations
instead of a single one are twofold: it helps lowering the computational complexity by
using simpler models, and it can improve the classification accuracy and performance.
Most Data mining applications are based on pattern matching algorithms, thus improving
the performance of the classification has a positive impact on the quality of the overall
data mining task. Since combination strategies proved very useful in improving the
performance, these techniques have become very important in applications such as
Cancer detection, Speech Technology and Natural Language Processing .The aim of this
paper is basically to propose proprietary metric, Normalized Geometric Index (NGI)
based on the latent properties of datasets for improving the accuracy of data mining tasks |

ANALYSIS OF DRAG AND LIFT FORCES IN DIFFERENT TAILED GROUND EFFECT VEHICLES |
Author : Pavan Hiremath, Manjunath Shettar, Suhas Kowshik C S, Rajath J and Sukhesh P D |
Abstract | Full Text |
Abstract :In recent days people are dependent highly on transportation and the demand for
quicker modes of transportation are increasing day by day. Technological advances in
the areas of roadways, airways and waterways have led to development of faster and
efficient vehicles which has largely contributed in connecting people across the globe.
This study deals with finding the effect of different forces acting on Ground Effect
Vehicles. Initially three different tail models were considered and modeled in CATIA
and then imported to ANSYS for further analysis. It was observed that the higher
pressure at tips is a result of the shape of the GEV and it causes drag, since it is
opposing the inlet flow. Lift is generated due to difference in pressures between top
and bottom surfaces of the wing, which is a consequence of velocity difference. The
pressure at top is much lesser that than bottom of the GEV, so lift is also generated.
However, it was found from L/D ratio that V tail displayed higher response for the
considered process parameters and boundary conditions. |

Abstract | Full Text |
Abstract :In Nigeria, plantain chips are in high demand and this demand is not being met by
most small scale food industries and shops due to some critical factors. Shops are only
able to fulfill approximately two-thirds of the demand. The biggest obstacle towards
attaining self-sufficiency in the production of plantain chips is the intensity of labor
involved and the tediousness of the process which often culminate into prolonged
production time. Plantain has a large amount of sap and this causes the skin to adhere
to the fruit inside. After peeling, they must be sliced into discs to fry into chips. Worker
will hold up to eight plantains in one hand and rapidly slice them using a wooden
mandolin. Because of the rapid pace at which they slice plantain and the absence of hand gloves on the workers, accidents are very often unavoidable. These presents
health hazards to both the worker, who may develop infections from their injuries, and
customers who may consume an unsanitary product. This development is very
uncomfortable and tasking on the workers. They must hold the mandolin over the fryer
so the plantains will fall in, which causes splashing of the boiling hot oil that
occasionally hits and injures the worker.
This research focused on design and fabrication of motorized / power operated
plantain slicer to meet the raising demands for plantain chips in Nigeria. The
objectives of this research was met as the machine has the capacity to produce
plantain chips of uniform size in shorter time and a greater slicing efficiency of up to
96.84% while keeping the cost of the machine at an affordable price. |

Author : Howrah M.A. Abbas, Ahmed R. Alhamaoy |
Abstract | Full Text |
Abstract :Glass Ionomer Cement (GIC) is one of the important dental materials used in
dental clinics, which is usually used in temporary restorative stages. This study aims
to evaluate the effect of adding Al micro particles to GIC powder (Riva self-cure) on
the mechanical and physical properties.The results showed that the addition of Al
micro particles has improved the compressive strength and biaxial flexural strength
where the highest values were at 3 wt. %, and then the compressive strength and
biaxial flexural strength decreased with increasing the added ratios. The addition of
Al particles improved the surface Vickers microhardness values where the highest
value was at 5 wt. %. The addition of Al has decreased the wear resistance of GIC;
however the wear resistance increased with increased adding ratios. The most acidic
beverages (the lowest value of pH) were the most effective in increasing the
absorption and solubility percentage of Al samples. Orange juice was more effective
followed by cola and then coffee and tea were less effective. We recommend that
patients reduce these acidic beverages because they have a harmful effect on dental
fillings.

Abstract | Full Text |
Abstract :Gas metal arc welding (GMAW) process is most widely used in industries for
fabrication works, due to higher productivity. The weld quality depends on the process
parameters of GMAW. This research investigates the influence of process parameters
affecting the mechanical properties of weldment. Thus, identification of the GMWA
process parameters that significantly affect the quality of GMWA processed parts is
more important in terms of productivity. Then process environment has been assumed
consisting of four variables like welding current, welding voltage, shielding gas, gas
flow rate and wire feed rate. Taguchi optimization technique has been applied to
determine the optimal limits, which can maximize the GMWA quality in certain
environment. Signal to noise ratio (S/N ratio) were calculated for each data and used
to obtain the optimum level of every input parameter. The study also shows that the
use of the Taguchi Method has productively enhanced on the existing process
parameters |

BIOFUEL PRODUCTION FROM MARINE MICROALGAE Nannochloropsis Salina USING PAPER MILL EFFLUENTS |
Author : P. Gurumoorthy, A. Saravanan |
Abstract | Full Text |
Abstract :The use of fossil fuels is unsustainable due to limited supply and also due to large
emissions of Carbon dioxide due to the effect of global warming. Biofuel is a viable
option but can, as produced today; only provide a limited amount of fuels needed.
Biofuels are presently derived from terrestrial plants, which require large amounts of
arable land. Biofuels from microalgae on the other hand do not necessarily require
arable land and can theoretically replace fossil fuels absolutely. Biofuels from
microalgae could use industry waste water as growth medium particularly paper
industry waste water is an interesting potential provider due to its high nitrogen and
phosphorus in waste water. In this research work marine microalgae Nannochloropsis
Salina was cultivated using f/2 medium using modified air lift photo-bioreactor along
with the paper industry effluent waste water, The doubling time calculated from
optical density attained at 48 hrs the cell count almost doubled during this period.
Since the marine species is sensitive to pH we need to maintain the pH at 7 below
7indicated the decreased biomass levels in culture. The lipid extraction was studied
using solvent methods. The functional compounds in lipids FAME were studied using
GC-MS analysis, the Nannochloropsis salina showed qualities of growing in fresh
water and brackish water apart from the marine water which is a desirable
characteristic for algal phycoremediation

Abstract | Full Text |
Abstract :The rapid increase in the occurrence of road accidents in Nigeria requires the
deployment of real time techniques that is equipped to reduce one of the critical
factor that have been identified by the Federal Road Safety cooperation of Nigeria
(FRSC) that constitute the major cause of road accidents which is over speeding. This
was achieved through the design and implementation of real time vehicle speed
monitoring system using cellular signal along the travelled path. A data acquisition
device was developed to capture in real time the signal strength and geospatial data
(longitude and latitude) along the travel path which is used in determining the speed
of the moving vehicle. The acquired data was correlated with data obtained from
standardize equipment to establish the integrity of the data, the data was then used to
develop the algorithm by obtaining equation for the path-loss gain in terms of signal
strength against distance. Equation for the base stations covering a distance of 10km
were obtained for analysis. Consequently from the equation, the distance from two
locations along the route can be determined from corresponding signal strength
values, the average speed results for the drive test, new Model and using Latitude and
Longitude are compared as followed 88.05km/hr, 75.67km/hr and 88.2km/hr respectively. With this a new paradigm shift in vehicular speed management is

Abstract | Full Text |
Abstract :This work presents the experimental results of gasification of char derived from
pyrolysis of Pongamia deoiled cake at maximum oil condition. Experiments are
conducted in fluidized bed reactor using air as the gasifying agent. The gasification
temperature and equivalence ratio (ER) were varied as per the designed experiment
using central composite design to study the influence on the composition of the
product gas. The lower heating value (LHV), Gas yield (GY), carbon conversion
efficiency (CCE) and cold gas efficiency (CGE) were calculated from the data of the
composition of the gas. The experiments were carried out in the temperature range of
600-800 °C, equivalence ratio of 0.26-0.36. Regression equations were proposed as a
function of temperature and ER for H2, CO, CH4 and CO2 in the range of
experimental conditions. The results showed that at a temperature of 800 °C and ER
of 0.35, maximum cold gas efficiency of 52.04% was achieved. The optimum input
parameters were identified for maximum gasification efficiency. The product gas with
highest LHV, 5 MJ/Nm3 was obtained at 600 °C temperature, 0.26 ER. The product
gas obtained through gasification of this kind of char can be used as fuel for syngas
engines, for power generation and process heat applications.

Author : G.V. Petrov, S.B. Fokina, A.Ya. Boduen, B.F. Fidarov and I.E. Zotova |
Abstract | Full Text |
Abstract :Inevitable depletion of mineral reserves involves search for the new alternative
sources of non-ferrous metals, in particular, noble metals. Chromite ores in dunite,
conventionally treated as refractory materials, are considered to be a prospecting
feedstock of platinum group metals. Studies were performed on platinum group metals
production as by-products for low-grade dunite ore processing. Gravity-magnetic
flowsheet for dunite concentration allows to extract magnetic platinum-containing
concentrate with high content of magnetite and platinum-ferriferous alloys. Reductive
leaching in sulfuric acid medium was considered as advanced method of refining of
magnetic platinum-containing concentrate from iron. Electrochemical studies of
magnetite cathode reduction in sulfuric acid medium showed that magnetite rate of
solution is increasing with potential shift to cathode region under increasing solution
acidity and higher temperature. Kinetics of cathode process can be determined by
electrolyte parameters and catalytic impact of cations of ferrous iron formed |

CINEMATIC PERFORMANCE IN THEATRICAL SHOW |
Author : Dr. Sarmad Saleem Abbas |
Abstract | Full Text |
Abstract :The study of the relations between the arts can lead to the causes of the spread of a
particular culture at a certain time in which it constitutes a technical development. The
actor did not start appearing through the screen in a theatrical performance without
accepting a year to collect the art of cinema with the art of the theater. The audience
understands the language of the picture and belongs to its contemporary culture. The
performance of the actor is cinematic in his performance in the cinematic theater, but this
performance is different from the art of cinematography, the representative scene is not
presented within the scenes of a film, and this performance is different from the art of
theatrical representation, the representative scene is not presented on stage. The
performance of the actor through the cinematic screen in the play is no less important in
the play than the actor on the stage in the contemporary theater. The use of cinematic
scenes in the play establishes a representative performance that is centered between the
stage and the screen. In the combination of theatrical and cinematic performances, a
frame of special artistic character characterizes the representation of features that
combine the performance of theater and cinema. |

INSOLVENCY LAW AND BUSINESS RECOVERY PRACTICES IN NIGERIA’S UPSTREAM PETROLEUM SECTOR: THE NEED FOR A PARADIGM SHIFT |
Author : Olujobi, Olusola Joshua and Olusola-Olujobi, Temilola |
Abstract | Full Text |
Abstract :Insolvency and business recovery practices are not at infancy stage in Nigeria,
although it has not crystallized to a full profession as it is practiced in other relatively
advanced climes. As the global financial sector evolves, the focus of modern
insolvency and business recovery practices have shifted from winding up of insolvent
oil companies to reorganization, restructuring of such companies and its operations to
foster economic stability and financial propriety. But the case is the reverse in
Nigeria, as liquidation is seen as the panacea to insolvency. The study evaluates
Nigerian insolvency and business recovery laws to sustain modern businesses
practices to prevent incessant corporate failure. Many jurisdictions are now
overhauling their insolvency and business recovery laws to support business practices
and to reform the gaps identified. The study conducts comparative legal and policy
analyses of solvency and business recovery laws in Nigeria, Malaysia, India, South
Africa, United Kingdom and United States. These countries were selected because
their insolvency and business recovery laws are business rescue driven. The study is a
doctrinal legal research that adopts a point-by-point comparative approach with
library research method. The study finds that Nigerian law on insolvency seems
deficient with regard to business rescue, turnaround and restructuring. It concludes
that, regulatory agencies in the selected countries are more effective than those in
Nigeria because of the political will of the governments of the former to successfully
turn around insolvent oil companies, save jobs and protect creditors by optimising
businesses through restructuring and business turnaround strategies. The study
therefore recommends reform of Nigeria’s insolvency and business recovery law and
practices in conformity with the global best practices on insolvent companies rescued
and creditors driven strategies for healthy economy. |

Author : I. A. Al-Ani |
Abstract | Full Text |
Abstract :Al-Hilla River has a great importance to the people in the vicinity which serves as
a main drinking and irrigation source. The aim of the current study is to estimate the
Water Quality Index (WQI) of Al-Hilla River, southern Baghdad using the weighted
arithmetic water quality index method. Water samples were collected from 7 stations
in March in which eight water quality parameters were analyzed: Turbidity, total
dissolved solids, dissolved oxygen, concentration of hydrogen ion, electrical
conductivity, chlorides, alkalinity and biological oxygen demand. The calculated WQI
of Al-Hilla River indicates that the river water is unsuitable for drinking which is
majorly attributed to the total dissolved solids and turbidity. This interprets the
condition of the river which can help the local authority in taking action by identifying
the sources of pollution and improving the water quality and stakeholders should be

Author : Diani Mardiana Mat Zin, Suziyani Mohamed, Mohd Izhar Ariff Mohd Kashim, Ezad Azraai Jamsari, Azmul Fahimi Kamaruzaman and Zaizul Ab Rahman |
Abstract | Full Text |
Abstract :This is an initial study which preceded the implementation of a 4-phase
collaborative action research using the Mac Naughton & Hughes model. The purpose
of this study is to explore the existing knowledge and practice of teachers in
implementing a thematic approach in the planning and implementation aspect of the
learning and facilitation process (PdPc). This early observation involved five teachers from different pre-schools. The data collected in a field study was through observation
and interview. Critical observation was based on comparison between two pre-schools
as the benchmark. Observation and interview of research participants found that
teachers of the two pre-schools had no in-depth understanding of the thematic
approach even though they admitted to using the National Pre-school Standard
Curriculum (Kurikulum Standard Prasekolah Kebangsaan or KSPK). Two teachers
made annual theme-based planning and only one made daily theme-based planning.
Three other teachers did not make annual theme-based planning but used topics in
workbooks as themes. All teachers arranged their schedule for child learning based on
separate subjects. All teachers frequently used a one-way teaching method, lacked
variety in teaching methods and stressed on academic development, while use of
textbooks and worksheets prevailed. This situation showed that the principle of
thematic teaching was unfulfilled, that is, teachers did not combine various subjects
and knowledge, child skills, variety of learning styles as well as child development
domains appropriate to age and ability. Research findings gives input to researchers
to make changes and improvements to teaching practice in implementing the thematic
approach through collaborative action research. A Guideline for Implementation of
Thematic Approach is required to assist and guide other teachers on how to begin the
process of implementing the thematic approach. |

STRENGTH AND DURABILITY PROPERTIES OF CONCRETE USING METAKAOLIN AS A SUSTAINABLE MATERIAL: REVIEW OF LITERATURES |
Author : Ayobami BUSARI, Joseph AKINMUSURU, Bamidele DAHUNSI |
Abstract | Full Text |
Abstract :The demand and use of concrete have led to a lot of research in improving its
strength, durability, life cycle, temperature effect and many more. Improving the
strength and durability of concrete is very paramount in the construction of basic
infrastructure in a bid to make it sustainable. The choice of metakaolin as a
supplementary material in improving the mechanical strength and durability of
concrete is espoused in this review. This was done in a bid to reduce the cost of
cement being one of the most expensive component of concrete production and to also
improve sustainability in the construction industry. The review revealed that the use of
metakaolin in the production of concrete showed an improved mechanical strength.
Literatures revealed that up to 10%-20% increase in mechanical strength is recorded
with the use of metakaolin in concrete production. Additionally, the durability
properties of concrete with metakaolin also improved. However, the review revealed
that incorporating metakaolin in concrete production reduced the workability of
concrete and increased the heat of hydration. The result of this review showed that the
use of metakaolin reduced the cost of producing concrete. Based on the uniqueness of
the material, it is recommended for use in countries where it is abundant in a bid to
promote sustainability in concrete technology, improve mechanical strength and
reduce cost |

RUNOFF ESTIMATION OF MINI WATERSHED OF PEDDA KEDARI RESERVE FOREST, TEKKALI, SRIKAKULAM, AP USING REMOTE SENSING, GIS AND SCS CURVE NUMBER TECHNIQUES |
Author : Dr. Ch. Kannam Naidu, S.Ramlal and Dr. Ch. Vasudeva Rao |
Abstract | Full Text |
Abstract :The primary source of water is rainfall for the generation of runoff over the land
surface. Runoff or overland flow is the flow of water that occurs when excess storm
water flows over the earths surface. Satellite remote sensing and GIS techniques
coupled with conventional filed investigations were used for mapping of land use/land
cover (LU/LC) features of the Mini Watershed of Pedda Kedari reserve forest towards
estimating the runoff of the Mini watershed. The SCS-CN method (SCS, 1985) method
involves the use of a simple empirical formula and readily available tables and curves.
Determination of SCS curve number depends on the soil and land cover conditions,
which the model represents as hydrologic soil group, cover type, treatment and
hydrologic condition. Soils are classified into hydrologic soil groups (HSG) to indicate
the minimum rate of infiltration obtained for bare soil after prolonged wetting.
Runoff computed from a given rainfall event was integrated with the data of land
use treatment, curve numbers and hydrological soil groups by using SCS-CN method.
The estimated runoff contributes more than 37% of total rainfall received in the study
area. The suitable locations of rainwater harvesting and artificial recharge structures
are suggested to increase the groundwater levels for sustainable development of water
resources in the Mini watershed of Pedda Kedari Reserve Forest.

Abstract | Full Text |
Abstract :This study is an experimental investigation that was undertaken to study the
reaction a selected lateritic soil sample to stabilization with asphaltic emulsion and
bagasse ash. This investigation is aimed at proffering a solution to the problem of
road construction and maintenance and also building construction and maintenance
with the existing and increasingly rampant situations of road failures, building
failures and collapse and also failure of bridges. The undisturbed soil sample
collected was mixed with 0, 4, 8, 12% asphaltic emulsion only, v then with 3, 6, 9,
12% asphaltic emulsion and 2, 4, 6, 8% bagasse ash simultaneously so as to
determine the strength characteristics of the lateritic soil sample. And a series of tests
were conducted on the various samples to determine their geotechnical properties
and suitability in road and building constructions. From the various tests it was
concluded that with the addition of the stabilization materials to the lateritic soil,
there was a positive change in the geotechnical properties of the soil sample. The
preliminary investigation carried out on the natural lateritic soil found in Landmark
University Omu-Aran, Kwara State Nigeria shows that it falls under Group A-2-7(0)
using AASHTO classification. The natural soil has a liquid limit value of 50, a plastic
limit of 21.7% and a plasticity index value of 28.3%. The maximum dry density
(MDD) of the soil was 1500kg/m3 and an Optimum Moisture Content (OMC) value of
23.7%. Unconfined compressive strength (UCS) values of 21.53 KN/m2 for 28-days
curing periods, respectively, were recorded for the natural soil. California Bearing
Ratio (CBR) value of 8.89% was recorded for the natural lateritic soil. Peak UCS and
CBR values of 40.48kN/m2 and 41.9% were recorded for soil treated with 9%
asphaltic emulsion 6% bagasse ash. The peak CBR value met the 20 – 30 %
requirement for sub-base reported by Sadeeq J.A. et al (2015) for materials
compacted at optimum moisture content.. |

TENSILE PROPERTIES OF FIBERGLASS AS REINFORCEMENT OF LOW-COST RUBBER BASE ISOLATOR FOR SMALL HOUSES |
Author : Budwi Harsono and Tavio |
Abstract | Full Text |
Abstract :Indonesia is one of the countries that has a very high seismic intensity. To meet
the standardization of the building design, several studies were conducted, including
the use of base isolation in residential buildings. The base isolator consists of several
layers of rubber and steel or lamination fibers which function to increase the vertical
stiffness of the isolator. Some has managed to use lamination fiber to make isolator
costs cheaper. This research uses fiberglass type net and woven roving types WR4
and WR6. Fiberglass is modeled according to the ASTM standard dogbone.
Fiberglass is tested as a standard matrix and is a composite. As a composite, the first
type is combined with 2504H Eternal resins and mepoxe catalyst, and second with
adhesive lord chemlok. The effect of curing on a temperature of 150 °C was observed
according to the conditions of making Low-Cost Rubber Base Isolation (LCRBI) on
the printing machine.
The result, fiberglass type Net matrix has a higher tensile strength compared to
other materials. For fiberglass net matrix composite has increased tensile strength in
the oven for 1 hour and returns to the oven for 2 hours at 150 °C. While the
composites of the WR4 and WR6 matrix materials have tensile strengths below 500
MPa and have a relatively small increase and decrease in value. Net type fiberglass is
suitable to be used as reinforcement on low-cost rubber base isolation for residential
areas, where with a small service load from the house it is needed a base isolator that
is not too stiff (optimal elastic). In addition, the fiberglass type net has a hollow
shape, allowing the layer between the rubbers to be more perfect for perfect
attachment |

Author : Dr. Engr. Gana A.J, Asebiomo |
Abstract | Full Text |
Abstract :The major construction material that cost more are cement and gravel which
makes buildings costly. Palm kernel shells are locally available materials which can
be used in place of gravel. Previous works on the kernel shell shows that the strength
determined have met with the building requirements.
Concrete is the most common material used in construction, various research
work and experience gained shows that the quality and durability of concrete depend
mostly on the properties of its constituent, mix design, method of preparation, curing
etc. have their influence on it.
Tests results have shown that kernel shell concrete of mix ratio 1:2:4 has average
compressive strength of 5.6 N/mm2 at 14days curing while 12.47 N/mm2 at 28days of
curing.
Palm kernel shell produces a concrete with a lower compressive strength in
comparison with normal concrete with gravel.
The project in conclusion was a success as it took into consideration the economic
status quo of the population. This project help to provide new materials affordable for
the low income earners which helps in producing low cost houses and this does not
remove the criteria of performance for a material |

Author : Abiola. M. Dauda, Joseph O. Akinmusuru, Oluwaseun. A. Dauda, Taiwo O. Durotoye, Kunle E. Ogundipe, Kehinde O. Oyesomi |
Abstract | Full Text |
Abstract :This study used eco-friendly materials known as Periwinkle Shell Powder (PSP) in
stabilizing the engineering properties of lateritic soil. Preliminary test was performed
on the un-stabilized lateritic soil for the purposes of identification and classification
(natural moisture content, liquid limits, plastic limits, and plasticity index). The
engineering tests were conducted on the lateritic soil stabilized with additions of (2, 4,
6, 8 and 10 %) PSP and OPC respectively. The result showed that cement gave a
progressive increase in the Maximum Dry Density (MDD) of the lateritic soil from
1875 kg/m3 (2 %) to 2294 kg/m3 (10 %) respectively. This represents 22 % increase
in the MDD from the un-stabilized state. For PSP, the Maximum MDD was attained at
6 % (1974 kg/m3), representing 5.3 % increase in MDD of the soil from the unstabilized state. For both stabilizing agent, the Optimum Moisture Content (OMC)
increases from 13.65 % to 13.83 % and from 11.72 % to 14.41 % for Cement and
Periwinkle Shell Powder respectively. PSP recorded an increase of 5.6 % of CBR
value compared with OPC that recorded an increase of 34 % CBR value. The study
therefore concluded that Periwinkle Shell Powder (PSP) could be considered as good
stabilizer for clayey or lateritic, and its uses as a stabilizer could also provide a big
relief to the environmental pollution caused by its indiscriminate dumping |

THE APPLICATION OF THE GRAPH THEORY FOR DEVELOPING AND TESTING THE SOFTWARE |
Author : Wessam L. Nados, Rusul J. Alsaedi and Qasim S. Kadhim |
Abstract | Full Text |
Abstract :The graph theory, which studies the properties of the graphs, has been widely
accepted as a core subject in the knowledge of computer science. In this paper, we
produced a method for developing an algorithm. The effectiveness of testing is the most
important factor for determining the cost and the duration of the development of the
large software products with a given quality, so the cost of testing for detecting errors
in the software reaches 30-40% of the total cost of its development and largely
determines its quality. The most commonly used of the testing methods are regression,
function, load, module, and optimization test if the graph is sufficiently complex. The
graph accelerates the testing process. We see the ways that we need to test. When they
cover all graph paths, the algorithm of the program is fully tested and does not need
any further development |

Author : Sergej Rudov, Vladimir Shapiro, Igor Grigorev, Olga Kunickaya, Varvara Druzyanova, Galia Kokieva, Aleksandr Filatov, Maria Sleptsova, Anatoly Bondarenko and Daba Radnaed |
Abstract | Full Text |
Abstract :Forest ecosystems on the cryomorphic soil grounds are very vulnerable. Harmful
effect of forestry machines upon the ecosystems of the felling-areas (due to
consolidation and deformation of the soil grounds) is well known in Russia and abroad.
Operation of forestry machines and yarding-and-loading systems in respect of
frozen soil grounds shows a clear need for taking this factor into account and
considering it as the complex multicomponent environment.
In the course of preparation of our article, our have developed and substantiated a
mathematical model and approach to assessment of lifting properties of the frozen soil
grounds. This model makes it possible to reformulate norms of operation of the forestry
yarding-and-loading and other machines.
Taking into account the approach, which we have proposed to utilize in respect of
simulation of the ground lifting properties, will make it possible to perform forest
management interventions in the least invasive mode, thus ensuring the faster natural
reproduction of the forest plantations, as well as the prolonged time framework
performance of the work that is connected with timber harvesting. In the conditions of
the Russian Extreme North, this fact may be transformed into an essential economic
effect. |

mortar can enhance many of the engineering properties such as flexural strength,
toughness, resistance to fatigue, 1 impact and thermal shocks as well as the failure
mode of concrete. The addition of discrete fibers of small diameter in the concrete
matrix has shown to improve its ductility. An experimental investigation was conducted
to examine the effects of concrete strength and fiber volume ratio on the flexural
strength of engineered glass fiber reinforced concrete beams. Five fiber volume
fractions, 0, 0.5, 1, 1.5 and 2%, and three concrete grades, M20, M30 and M40, were
designed for the study. The results showed that the flexural strength increased with an
increase in fiber volume fraction and the strength of concrete. |

PROCESS SOLUTIONS OF ZINC-CONTAINING WASTE DISPOSAL IN STEEL INDUSTRY |
Author : S.B. Fokina, G.V. Petrov, E.V. Sizyakova, Yu.V. Andreev and A.E. Kozlovskaya |
Abstract | Full Text |
Abstract :Steel industry can be characterized by a significant amount of by-products
including fine dust (up to 1.5% of heat size). Dust of gas cleaners, containing above
0.5% Zn and 50% Fe, cannot be directly returned to basic melting facilities due to high
contents of zinc that destroys its lining. High consumption of reducing agent, furnace
lining corrosion, final product of high impurities content made difficult use of
hydrometallurgical processing. Use of hydrometallurgy technologies is held back by
zinc in dust, primarily, as ferrites that cannot be opened using alkali, while acids make
iron transfer into solution. As a result, major part of smelters stockpiles the dust.
Secondary deposits of zinc-containing steelmaking dust can be involved into processing
thus expand the feedstock of zinc industry, increase efficiency of steel making and
reduce negative impact on environment.
The paper contains chemical and mineralogical analysis of steel dust sample from
PAO Severstal and study results on hydrometallurgical extraction of zinc from dust
using salt solution. It has been established that ammonium chloride leaching of zinc from electric arc furnace dust takes place within external diffusion region; optimum
parameters of ammonium chloride leaching can result in almost complete and selective
extraction of zinc into solution and producing ferrous cake that is applicable for blastfurnace processing. It was revealed that higher level of zinc ferritization in leach has
minor negative impact on zinc extraction into solution and keeps minimum iron transfer
into solution. Zinc can be extracted from leach solution by zinc hydroxide deposition
using ammonia stripping, followed by drying and deposit calcination to produce
saleable zinc oxide.

PERI URBAN DEVELOPMENT IN DEVELOPING COUNTRIES |
Author : Ar Manita Saxena and Dr. Supriya Vyas |
Abstract | Full Text |
Abstract :Peri-Urban regions are to a great extent characterized as the zones that
encompass our metropolitan regions and urban areas - neither urban nor rustic in the
regular sense. They are the quickest developing areas in numerous countries. The
Peri-Urban zone can be viewed as not only a periphery in the middle of city and wide
open, a zone of change; rather it is another sort of multi-practical domain. While it
opposes basic definitions, there are basic highlights wherever such territories are
discovered, for example, a moderately low populace thickness by urban guidelines,
dispersed settlements, and high reliance on transport for driving, divided networks
and absence of spatial administration.
Numerous worldwide difficulties emerge from the manners in which that urban
communities develop and change, particularly the rising super urban communities in
creating nations where huge social and natural issues can be found in their PeriUrban hinterlands. Issues of Peri-Urban zones in creating countries are very not the
same as that of created nations.
Peri-Urban is a testing and topical subject from numerous points of view. It is
positively a test for logical research. This paper will manage approaches/instances of
arranged development measures for Peri-Urban zones in countries of landmasses like
Asia, Europe, and so forth. A few nations have given considerable regard for these
issues.
It will be considered how these nations have managed the heedless improvement,
framework issues, administration, and so on. Proposition of comparable kind can be
proposed for developing nation like India |

Abstract | Full Text |
Abstract :The paper presents the results of theoretical understanding of trends, prospects and
limitations that exist in the training of personnel for agriculture in the context of digital
transformation of the economy.The transition to the target settings of the new
technological order, which is associated with the spread of digital technologies,
requires the solution of a whole range of problems in the field of training.The
widespread introduction of digital technologies sets the task for universities to train
personnel with competencies that are not currently reflected in the current Federal
Educational Standards for such directions of training as: “Agriculture, Forestry and
Fish Industry”, “Industrial Ecology and Biotechnology, Earth Sciences”, “Electric Power and Heat Power Engineering”, “Veterinary Science and Zootechnics”. The
article presents the results of a survey conducted among students, which characterize
the attitude of future graduates to the prospects of digitalization of agriculture. The
study showed on the one hand the disunity of respondents opinions on certain aspects
of the use of digital technologies, on the other hand a great interest in the issue under
study. It should be noted that the digital transformation of the economy has exacerbated
the problem of staffing agriculture and other sectors of the economy.

Author : E. E. Ekong, Q. E. Adiat, J. O. Ejemeyovwi, A. M. Alalade |
Abstract | Full Text |
Abstract :The Big data concept emerged to meet the growing demands in analysing large
volumes of fast moving, heterogeneous and complex data, which traditional data
analysis systems could not manage further. The application of big data technology
across various sectors of the economy has aided better utilization of multiple data
collated and hence decision making. Organizations no longer base operations on
assumptions or constructed models solely, but can make inferences from generated
data. Educational organizations are more efficient and the pedagogical processes
more effective, when multiple streams of data can be collated from the various
personnel and facilitators involved. This data when analysed, maximizes the
performance of administrators andrecipients alike. This paper looks at the
components and techniques in bigdata technology, and how it can be implemented in
the education system for effective administration and delivery. |

APPLICATION OF CENTRIFUGAL MODELING FOR THE STUDY OF LANDSCAPE STRUCTURE STABILITY |
Author : D. Ignatenko, O. L. Tiutkin, V. D. Petrenko, A. M. Alkhdour |
Abstract | Full Text |
Abstract :The calculation of stability by mathematical methods of complex shapes of slopes
with a diverse geological structure is reduced to simple formulations and assumptions
for finding curves of sliding surfaces and for forecasting possible forms of stability
loss. The method of centrifugal modeling allows us to conduct in-depth studies of the
experimental, reproduced, reduced scale of the slope and to reliably identify the
nature of the existing deformations after rotation on a centrifuge, analyze them and
draw conclusions about the stability of the studied slope.
The centrifugal simulation can be divided into four stages, each of which is
described in detail in this article with reference to photo materials and descriptions.
The obtained results of the centrifugal modeling of the shifting slope of the
Krasnopovstanska ravine and the analysis of the deformed state of the model before
and after placement of soil cement piles in the body of the slope.
Centrifugal modeling is not a new method for studying the stability of slopes. This
method requires special complex hardware and hardware, therefore, it is used rather
infrequently. Conducting this type of research is accompanied by a small amount of
informative literature on the methodology of the simulation itself. This article is
devoted to the question of conducting and successfully using the method of centrifugal
modeling of landslide slopes with the observance of certain features.
Application of the technique of centrifugal modeling allows solving problems of
calculating the stability of natural slopes with complex geological structure. |

Author : Anom Wiryasa NM and Jaya NM |
Abstract | Full Text |
Abstract :Sustainable development has been environmentally adopted into a development
concept implemented in regulations/ legislations in accordance with the fourth
amendment to the 1945 Constitution of the Republic of Indonesia (UUD 1945).
Sustainable development is influenced by three aspects, namely: social aspects;
economic aspects; and environmental aspects. Conventional development takes into
account the influence of social and economic aspects, so in this study reviewing the
influence of environmental aspects in the era of nowadays sustainable development.
The purpose of this study is to analyse the elements of environmental aspects in form
of a Model of Structural Hierarchy (MoSH) that affects sustainable development.
Environmental aspects elements are analysed by the Interpretive Structural Modelling
(ISM) method. The ISM method was chosen to help decision makers in determining
policies in accordance with the resulting a MoSH. Thus, the MoSH in the field of
environment which is associated with sustainable development is a new contribution
in the area of sustainable development |

THE SEISMIC PERFORMANCE OF RESIDENTIAL HOUSING UNDER STRONG EARTHQUAKE SHAKING |
Author : Hidajat Sugihardjo and Yudha Lesmana |
Abstract | Full Text |
Abstract :The base isolation system is well-known as a sophisticated device for reducing
earthquake energy that a building structure is subjected to under earthquake impact.
Currently, many researchers are attempting to develop low-cost base isolation
intended for low-rise buildings by replacing steel reinforcement with an alternative
material. In this research project, the seismic response of residential housing units
that used perforated-reinforced elastomeric isolators (PREIs) within one- and twostory reinforced concrete (RC), are investigated. The nonlinear dynamic analysis
(time history) considered seven ground motions to assess the seismic performance of
the structure under extreme earthquake shaking. The nonlinear dynamic analysis
method was developed to provide a more realistic model of structural response to
strong ground shaking. The lateral displacement, inter-story drift, base shear,
acceleration and overturning moment were analyzed to ensure that the low-rise
building behaved elastically under strong ground motion without any damage on both
nonstructural and structural components. The results illustrated that the application
of the isolators in the low-rise building was reliable in providing low horizontal
stiffness and a longer fundamental period. In addition, the study illustrated the
advantage of applying isolators in the upper structure, reducing base shear,
acceleration and drift ratio drastically. The large lateral displacement of the isolator
played an important role in the stability of the isolated structure. Therefore, special
attention must be paid in the design process of the isolator to guarantee suitable
response of the upper structure under strong earthquake shaking |

Author : Lambang Basri Said and Ilham Syafey |
Abstract | Full Text |
Abstract :The research objective is to evaluate the performance of intersections around the
central area of urban activities, analyze queues and delays that occur in the area,
openings and existing canalization, analyze the level of accessibility from the
influence of traffic management, from obstacles to various privacy activities,
determine the optimization of traffic light functions coordinated and integrated. The
research method is generally carried out through direct surveys, mathematical
analysis and comparative analysis. Mathematical analysis is done iteratively to get the
best cycle time as an integrated and coordinated intersection function. Graphically, it
can facilitate the drawing and reading of the best cycle times for various intersections
that are included in the design. The results obtained showed that the densest traffic
volume in the CBD area occurred at the intersection 7 and 12, with the 42.02–72.59%
composed of vehicles dominated by motorbikes, while jeeps between 6.72 – 35. 63%.
The capacity of Intersection in this area averages 6,809 passenger car unit (pcu) /
hour, so that the Degree of Saturation averages 0.895 with the maximum is 0.917. The
highest chance of queuing occurs in unsignalized intersections in the CBD area
between 42-84% which occur at the intersection 7 and 12 with the highest delay was
38.18 seconds (intersection 2). The level of accessibility of this region was high but
because of the high side barrier. Intersection capacity improvement through
geometric improvements, channelization, improvement and optimization of integrative
traffic light functions, has the potential to contribute up to 36% and based on
simulations with VISSIM program aids until the projections for 2025 can be
maintained contributing to an increase in capacity of up to 22%.

FACTORS CONTRIBUTING TO THE VALUATION OF ARTS AND ARTIFACTS IN OGUN STATE, NIGERIA |
Author : Ibisola, A.S., Durodola, O.D, Oluwatobi, A.O., Oni, A.S., Peter, N.J |
Abstract | Full Text |
Abstract :Arts and artifacts of various forms and sizes adorn different areas of property
either on the wall, in the boxes or on the shelves. There are also evidences of uses of
arts and artifacts for commerce. These and other uses of art and artifacts necessitated
their valuation just like it is done for land and buildings. Estate surveyors and valuers
are called upon based on the dictate of the Nigeria Law, their academic and
professional trainings to advise various stakeholders who may have one thing or the
other to do with arts and artifacts to help them in determining the value for such a use
or uses. Despite this enabling criteria, Estate Valuers are confronted with challenges
in identifying, separating and analyzing the factors that determine the values of arts
and artifacts. This study examines the various factors that determine the value of arts
and artifacts. A structured questionnaire was designed and administered on 17 Estate
Surveying and Valuation firms in Abeokuta, Ogun state. The data gathered were
analyzed using Mean Weighted Score (MWS) and frequency distribution. Common
factors considered in the process of arts collection include the buyer’s perception,
condition and quality of the artwork among other factors. Findings revealed that most
art buyers collect artifacts at certain huge amount primarily because of their own
definition of the arts, outstanding aesthetics and thereby developing personal opinion
of art value while the role of a professional property valuer is displaced from the
process. This study therefore concluded that there should be a defined process of
valuing artworks by property valuers which will include a guideline defining the
factors to be considered in art and artifact valuation, thereby encouraging uniformity
of value estimation of such personal property as it is for land and building valuations. |

Author : Bara Wasfi Al-Mistarehi, Taisir S. Khedaywi, Yasmeen Taleb Obaidat |
Abstract | Full Text |
Abstract :Environmental problems have been counted as a critical topic in the construction.
The issue of throwing away waste materials is considered as a pivotal subject in
modern engineering orientation. Reuse, recycling and reduce the wastes suppose as
the only methods to recover those waste created. Polystyrene is considered as one of
the materials vastly utilized in manufacturing applications. The purpose of this paper
is to investigate the possibility of using recycled polystyrene as an additive to asphalt.
The polystyrene waste was added up to asphalt by volume to the asphalt in 0, 5, 10, 15
and 20%. Penetration degree, ductility, specific gravity, softening point, flash and fire
point, Dynamic Shear Rheometer (DSR), Bending Beam Rheometer (BBR), Rolling
Thin Film oven (RTFO) and Pressure Aging Vessel (PAV) tests were performed in this
research study. In general, the results in this study indicated that the addition of
polystyrene into asphalt increases the penetration, ductility and flash point. On the
other hand, it decreases the softening value and specific gravity. It found also that the
rutting decrease due to the additives of polystyrene and similar trends in critical high
temperature cracking and fatigue cracking resistance observed. Furthermore, the
effect of polystrene influenced significantly the creep behavior by increasing the creep
rate and decreasing the creep stiffness and low temperature. That means the
resistance of thermal cracking would increase by polystyrene contents |
