Water coning is a serious issue for the oil and gas industry. This poses a big concern regarding the costs that to be incurred for separation and equipment capacity. Coning is the production of an unwanted phase with a desired phase. Over the years, many techniques and control methods has been birthed, however, the issue of coning can only be mitigated and not completely discharged. Reservoir and production engineers need to understand the basic framework; the parameters that greatly influence coning and how effective manipulation of it can deal with it. With the introduction of horizontal wells, the production rate is two to four times that of vertical wells, and coning is reduced and the breakthrough time is increased. Numerous papers has been written regarding to coning and vertical wells, only a few emphasize on horizontal wells and simultaneous water coning and gas coning. The objective of this research is to study the post breakthrough performance in simultaneous coning and a black oil simulator was use for the research. Sensitivity analysis was carried out on: the production rate of oil (qt), horizontal permeability, vertical permeability, perforation length, the height above perforation, extent of reservoir area and the formation porosity. A generalized correlation was developed for predicting coning behavior using non-linear analysis.

The asphalt industry has been perpetually challenged by its hazardous emissions and its contribution to the ongoing climate change and global warming crises. Likewise, the environment has been cumbered by the challenge of improper disposal of nondegradable solid wastes especially crumb rubber in form of scrap tyres resulting in serious environmental degradation. This research investigated the effect of modifying bitumen with bio-oil from cassava peels upgraded with a nondegradable polymer i.e. crumb rubber. Performance tests were carried out on the modified bitumen to evaluate its effect on its rheological properties. The percentage of bio-oil by volume used for modification of bitumen was 5%, 10%, 15% and 20%. Marshall Stability and flow tests were also carried out on the bio-asphalt produced. Experimental results of bitumen modification with cassava peel oil at 5%, 10%, 15% and 20% replacements showed an increment in flash point of 244°C, 250°C, 252°C & 259°C fire point of 259°C, 265°C, 269°C & 274°C and softening point values of 55°C, 55.5°C, 56.5°C & 57.5°C respectively of the base bitumen. Due to the high moisture content associated with biooils, properties such as ductility and viscosity were adversely affected. Upgrading with crumb rubber caused an improvement in the engineering properties of the base bitumen with penetration grade at 20% modification showed the resultant blend was 40/50 which is suitable for use on airport pavements. The highest Marshall Stability and Flow values were obtained at 20% modification with bio-oil upgraded with polymer with values of 26.5kN and 13.33mm as against 9kN and 10.5mm obtained on the control sample. Finally, it was observed that the bio-oil could be utilized in the production of cutback bitumen due to the reduction of viscosity

The primary objective of this project is to extend the conveniences of deconvolution to non-linear problems of fluid flow in porous media. Unlike conventional approaches, which are based on an approximate linearization of the problem, here the solution of the non-linear problem is linearized by a perturbation approach, which permits term-by-term application of deconvolution. Because the proposed perturbation solution is more conveniently evaluated in the Laplacetransform domain and the standard deconvolution algorithms are in the time-domain, an efficient deconvolution procedure in the Laplace domain is a prerequisite. For this research objective, a new algorithm is introduced which uses inverse mirroring at the points of discontinuity and adaptive cubic splines to approximate rate or pressure versus time data. This algorithm accurately transforms sampled data into Laplace space and eliminates the Numerical inversion instabilities at discontinuities or boundary points commonly encountered with the piece-wise linear approximations of the data. Applying the algorithm to the field data obtained from published works, we can unveil the early-time behavior of a reservoir system masked by wellbore-storage effects. The wellbore-storage coefficient can be variable in the general case. The new method thus provides a powerful tool to improve pressure-transient-test interpretation. Practical use of the algorithm presented in this research has applications in a variety of Pressure Transient Analysis (PTA) and Rate Transient Analysis (RTA) problems. A renewed interest in this procedure is inspired from the need to evaluate production performances of wells in unconventional reservoirs. With this approach, we could significantly reduce the complicating effects of rate variations or shut-ins encountered in well-performance data

Issues of population explosion has evoked several images characterized by emotional, value-laden and often paranoiac connotation that cannot be obviously ignored considering its threatening challenges. It is against the foregoing that this paper attempt to interrogate the relevance of Thomas Malthus theory on population and the challenges of the bourgeoning population explosion in Nigeria. The core objective of this paper is to investigate the relevance of the theory on Nigeria’s population. Other objectives are to ascertain the effects of the population explosion on the Nigerian urban areas; food security, crimes and security and poverty. In terms of methodology, the paper relies on an explanatory design and some empirical data generated through secondary sources and official documents were examined. The data were analysed using a descriptive method of analysis. The paper identified the relevance of Malthus theory on the bourgeoning population explosion on the following key areas: Food Security; Poverty Rate; Urbanization; crimes and Security Threat. After examination of official documents and secondary data, the paper concludes that population explosion has continued to undermine the achievement of development’s goals in Nigeria. A population growing faster than the output of modern goods and services not only frustrates development goals; it undermines the credibility of promises made in the name of development and political will to pay the price of progress. The paper among other things recommends for the promotion of mechanized farming; engage public private partnership for investment and financing of agricultural productivity and housing; and the era where population increase is seen by many in Nigeria as the key to the control of political power and resources should be discarded and a proactive approach adopted.

Vibratory welding is a non-thermal method to reduce the residual stresses. In vibratory welding, mechanical mode of vibrations is imparted to the specimen during welding. This paper presents influence of mechanical vibrations (voltage input to the vibromotor) on the hardness of aluminium alloy weldments. Vibratory Tungsten inert gas welding is applied to join alloy weldments. In this hardness values of aluminium alloy weldments are analyzed for different vibromotor voltage inputs keeping other parameters constant i.e., flow rate of gas, speed of welding, weld current and the vibration time of the specimen. It is observed that hardness of aluminium alloy weldments is increasing with voltage input to the vibromotor from 50 V to 160 V. it is also noticed that the hardness of aluminium alloy weldment is decreasing when the voltage input to the vibromotor is more than 160V

The Nigerian construction industry is one of the largest construction markets in Africa. It consists of foreign and indigenous contractors, construction professionals, public and private clients and material manufacturers. However, gross dissatisfaction of clients as a result of poor work quality, cost overruns and time overruns is inhibiting the growth potentials of the industry. Innovation holds great potentials for improvements in the industry. However, there is a need to understand the drivers and barriers to innovation. This study assessed the drivers and barriers to innovation. This study adopted a quantitative research design with questionnaires distributed to construction professionals in consulting and contracting firms located in the Mainland area of Lagos State. Data from the survey were analyzed by descriptive statistics and presented in form of frequencies, charts and mean. The major drivers of innovation from the survey were clients’ requirements, developments in ICT and design trends while the main barriers to innovation as perceived by the respondents from the study were lack of understanding of the benefits of innovation, perception that the industry is doing well without innovation and cost of innovation. If the industry must improve its growth potentials then, innovation is not negotiable. However, construction stakeholder will need to address the barriers to innovation identified in this study

In developing processing machines for plant materials, the frictional property of the seed on structural surfaces of Mild steel (MS), Plywood (PW), Concrete (CC) and Glass (GL) is a parameter which needs to be measured. In this study, the static coefficient of friction of two Nigerian beniseed accessions (Yandev-55 and E8) were determined at moisture content levels of 5.3, 10.6, 16.1 and 22.4 per cent (wet basis). These were used as inputs into designing a beniseed oil expeller. A - 2 x 4 factorial experiment in completely randomized was used for the study. The static coefficients of friction between beniseed and the four structural surfaces increased curvilinearly with increase in moisture content irrespective of the surface employed. The result showed that glass has the least value of 0.32 while for mild steel, plywood and concrete, frictional coefficients with beniseed were between 0.39 to 0.59 within the 5.3 and 22.4% moisture content levels. The effect of moisture content is highly significant on the coefficient of frictions of all the tested surfaces..

Epilepsy is one of the prominent and disturbing neurological disorder and many people across the world are victims of this problem. The sudden motor disturbances in the brain cause and trigger these seizures. Due to the hypersynchronous discharges happening on the cortical regions of the brain, the activities of the motor becomes abnormal and so seizures are triggered. The seizures caused due to epilepsy are quite heterogeneous in nature and so diagnosing it is quite challenging. Electroencephalography (EEG) is the most widely used instrument for the detection of epileptic seizures. In this work, Haar and Sym8 wavelets are employed to extract the wavelet features at level 4 from EEG signals. The extracted features like alpha, beta, theta, gamma and delta are classified through the Soft Discriminant Classifier (SDC) to obtain the epilepsy risk level from EEG signals. The final results show that when Haar wavelet is employed and classified with SDC, an average classification accuracy of 95.20% is obtained and when Sym8 wavelet is utilized and classified with SDC, an average classification accuracy of 94.68% is obtained

Flexural strength also known as the bending strength which plays a vital role in the industries where the heavy load application is implemented. The study reports show that shotpeening technique considerably improves the mechanical properties of a material such as hardness, fatigue strength, corrosion resistance, flexural (or) bending strength etc. Here the shot material used for shotpeening is glass beads and the target material is aluminum alloy of grade AA-2024 T3 which is widely used in the automobile and aircraft industries due to its light weight and strength. The experimental results show there is an improvement in the flexural strength of AA2024-T3material after shotpeening

Electric vehicle range is very important while designing an electric vehicle energy storage system. So an energy storage system must be designed according to the vehicle power, torque required and speed of the vehicle. So the capacity and energy must be according to vehicle parameters. But there will be range anxiety i.e. the discharge time of the battery is a problem. Due to load variations and speed variations battery will drain fully before the expected time which is calculated theoretically. So to avoid this problem a new method is introduced in this paper. In this method the total energy requirement is calculated including the efficiency factor. Then an extra percentage is added to that and the total energy storage system capacity is fixed. Then the total energy storage system is split in to two as main battery pack and auxiliary pack. Then the first part is allowed to charge fully and the next part is charged through solar panel pasted on the car body. After the charging of first part the car is started and allowed to move. When the SoC has discharged fully, main pack is cut off and the auxiliary pack is ON, simultaneously the main pack is charged. This strategy will help to improve the range of electric vehicle when compared to a vehicle without solar panel and only single set of battery pack

Melon shelling machine was designed, constructed and evaluated. Shelling efficiency and cleaning efficiency were evaluated for on the machine. The design adopted the method of shelling by attrition. The major machine elements of the shelling machine are the hopper, shelling chamber and the separating chamber. The hopper is made up of welded galvanized sheet slanted at 23° which is the coefficient of static friction of melon on galvanized sheet. The shelling chamber has an impeller which consists of two circular disks with 24 vanes positions in between the disks. The vanes are inclined at an angle of 45° to the horizontal axis. The minimum power required for the impeller was calculated to be 598.2W and the terminal velocity was calculated to be 7.6 m/s. Evaluation was carried out for the machine shelling efficiency and cleaning efficiency using three levels of moisture content (3.79% d.b., 6.61% d.b. and 9.53% d.b.) and three levels of impeller speeds (800, 1000, and 1200 rpm). The results showed that the moisture content had a significant effect (at P<0.05) on the shelling efficiency and cleaning efficiency. However, the impeller speed has a significant effect only on shelling efficiency. The optimal values of the shelling efficiency and cleaning efficiency were 39.1% and 70.3% respectively with machine loss of 4.5% at 3.79% d.b. and 1200 rpm

Hybrid polymer composites are the materials made by combining two or more different type of fibers in a matrix. Hybrid polymer composite material offers the designer to obtain the required properties in a controlled considerable extent by the choice of fibers and matrix. The properties are tailored in the material by selecting different kinds of fiber incorporated in the same resin matrix. They offer wide range of properties that cannot be obtained with a single type of reinforcement. Due to its high specific strengths, high specific modulus, low densities, light weight etc. based on its applications. Presently they are playing a vital role in aerospace, defence, transport, sport applications. Worldwide researches are keenly interested in finding out their behavior in real life exposed to various environmental conditions, variety of loads etc. In this paper, We fabricated carbon, e-glass and hybrid composites by using hand layup technique in uni-directional orientation with epoxy as a matrix material and conducted various tests such as tensile, compression on Universal Testing Machine (UTM) and hardness. The results are validated with FEA and observed that Al-6061- T6 which is used in manufacturing of military aircraft landing mats, truck bodies and frames etc. has a tensile strength of about 310.25Mpa.The tensile strength of hybrid fiber is 341Mpa which is higher than Al 6061-T6. We have compared the experimental results with ansys results and found that the experimental values are very close to the ansys results. But when compared within the fibers carbon fiber exhibited more strength when compared to other fibers

This study investigates the relationship between quality of work-life and organizational commitment in the academic environment. Dimensions of quality worklife examined include career advancement, job security, pay benefit and employee participation in decision-making. The study adopted the survey method with data collected from a sample of two hundred and ninety-three (293) randomly selected respondents in a private-mission owned university in Nigeria. Results of data analysis indicate a negative relationship between career advancement, job security and organizational commitment. However, positive relationship was found to exist between employee participation, job satisfaction and organizational commitment. The study suggests the imperative for tertiary education institutional managers to prioritize specific dimensions of employee quality of work-life as an integral antecedent to the achievement of organizational objectives. This holds promise to attaining global standards

Distributed Denial of Service (DDoS) attack is the most severe cyber-attack that affects the availability of critical applications. The attackers identify the weakness in the machines and compromise them to involve in the flooding attack. During the DDOS attack generation, they also gain access to secret information. These computers are then used to wage a DDoS Attack in host’s computer. Through many security measures have been taken in order to stop DDOS Attack to be protect our data, the attackers have developed new techniques and attack methodology. Hence it is very important that instead of reacting to new attacks, it is necessary to build a complete DDoS solution that will defend all types of DDoS attacks. So, the researchers must understand the cyber space and methods utilized to block the DDoS attacks. The proposed system provides a unique method to detect DDoS attack using Splunk. We propose two methods for prevention of DDoS attack. One is using Randomly generated Captchas and other one is using Linux bash script to prevent DDoS attack by automatically blocking IP of the client, who is sending multiple request at a time.

There is proposed a detailed model for a decision support system for investment in SMART CITY technologies. The model is distinguished by the assumption that the first investor does not have complete information, both about the financial strategies of the second investor and about the states of his financial resources aimed at SMART CITY investing. In this case, the first investor has the opportunity to obtain additional information by the expense of a part of his financial resources. The last one makes it possible for the first investor to get a positive result for himself if he cannot get it without this procedure. Considered variants of rational behavior of investors. Imitation experiments confirmed the adequacy of the model. The deviation of the results of a simulation experiment from practical data does not exceed 9–12%.

The addition of dynamic positioning system on offshore auxiliary vessels leads to the installation of a large powered bow thruster. Unpredictable fieldwork conditions lead to uncertain loading. Changes in electrical system configuration and load shedding scheme are just a few of the many ways to maintain electrical system stability. This method is done in order to balance the generator mechanical power generated with the load needs. The configuration changes has been made and the result was that the closed bus of 2 generator thruster and 2 diesel generator configurations have excellent stability that can reach stable conditions with 110% loading on each bow thruster. While Rhe closed bus configuration of 1 thruster generator and 2 diesel generator provides an opportunity to rest 1 generator thruster to save generator usage. However, the stability of this configuration can be improved by conducting a load shedding scheme

The economics taught and applied in Indonesia are monistic, and the same thing is applied in almost all universities in the world since the Second World War. The economics is also taught and applied at Medan State University by referring to Paul Samuelson book entitled “Economics: An Introductory Analysis”. The book emphasizes the dogmatic orthodox economics theory by teaching classical and neoclassical perspectives. If economics is only taught from one perspective it is very contradictory when tested using empirical evidence because it will only touch aspects of the introduction of knowledge, values and theories of economic orthodoxy that are far from the real world economy. Monistic learning processes such as this, of course, have not been able to increase active involvement and arouse students critical attitudes; thus, limit students to developed skills, and to understand economic and social issues more broadly. Therefore, it is necessary to use appropriate pedagogy in teaching macroeconomics to students. This article aims to explain the importance of pluralism in macroeconomic learning and the challenges faced and see students perceptions of economic pluralism. The results of this study indicate that the perceptions of students using focus groups analyzed using Nvivo software show that students enjoy learning pluralism and are able to improve their ability to analyze, criticize, assess, understand, and have better writing skills.

Groundwater is a unique kind of mineral resources, relation to which should be special in our modern world. Geology of the earth surface is arranged in such a way that boundaries of groundwater aquifers and complexes distribution do not coincide the boundaries of states, and therefore extraction of this priceless resource must be regulated at the international level. Aquifer exploitation occurs in all the countries at all the continents in accordance local legislative norms. Many international conflicts can be prevented if one approach the problems of subsoil use on the basis of a general agreement. The aim of the research is development of an international conceptual model for groundwater production management through regulation of specification systems, monitoring, licensing, control of groundwater extraction. Features of groundwater extraction from transboundary aquifers are considered, international experience of conflict regulation in this sphere is reviewed, environmental measures are offered, recommendations and prerequisites for development of an international system for groundwater extraction management are given.

Internet becomes the most popular surfing environment which increases the service oriented data size. As the data size grows, finding and retrieving the most similar data from the large volume of data would become more difficult task. This problem is focused in the various research methods, which attempts to cluster the large volume of data. In the existing research method Clustering-based Collaborative Filtering approach (ClubCF) is introduced whose main goal is to cluster the similar kind of data together, so that retrieval time cost can be reduced considerably. However, existing research methods cannot find the similar reviews accurately which needs to be focused more for efficient and accurate recommendation system. This is ensured in the proposed research method by introducing the novel research technique namely Modified Collaborative Filtering and Clustering with Regression (MoCFCR). In this research method, initially k means algorithm is used to cluster the similar movie reviewer together, so that recommendation process can be done in the easier way. In order to handle the large volume of data this research work adapts the map reduce framework which will divide the entire data into subsets which will assigned on separate nodes with individual key values. After clustering, the clustered outcome is merged together using inverted index procedure in which similarity between movies would be calculated. Here collaborative filtering is applied to remove the movies that are not relevant to input. Finally recommendations of movies are made in the accurate way by using the logistic regression method. The overall evaluation of the proposed research method is done in Hadoop from which it can be proved that the proposed research technique can lead to provide better outcome than the existing research techniques

Principle Component Analysis (PCA) is a widely used technique in the field of face recognition. Any system will have its own pros and cons. One of the disadvantages of PCA is its bonding with the light variation. By focusing on this issue, an improved algorithm is proposed by combining PCA with the Fast Fourier Transofrm-2. This solution is then applied to a real time environment which provides the smart access to the house. The user interface is provided using the Android application installed on the user’s smart phone. The communication between the smart access system and the application can happen remotely. The mechanical door lock is controlled using the system which can receive and transmit the command

The traditional technique for testing water and soil quality is to accumulate their examples and send to the work to check and break down. This system is tediousand not conservative. The water quality estimating framework that we have got actual checks the character of water endlessly through appropriate sensors. In standard farming, development of the plants is used to continue and upgrade human life. the event in our country is greatly diminished owing to absence of intrigue, shortage of farming land and water and many agriculturists with their own advantage they need been doing the event at this. In any case, that to boot respects less creation owing to absence of attentiveness regarding the land waterlessness, no opportune chemical uses and affordable harvests for the land. The Wi-fi module exchanges data gathered by the sensors to the controller, and exchanges the data to the computer. This system continuously monitoring the contamination of the water assets, soil quality.

The total use of vehicles increasing, causing the need for diesel fuel has increased as well. The more use of diesel vehicles causes the more exhaust gas emissions produced. Therefore, it affects the risk to human health. Exhaust gas emissions can be reduced by blending biodiesel-diesel fuel. Biodiesel made by esterification process of waste cooking oil obtained from the process of frying food. Furthermore, diesel fuel blended with 12.5% v/v of biodiesel-diesel (B12.5), 15% v/v of biodiesel-diesel (B15), 17.5% v/v of biodiesel-diesel (B17.5) and 100% of biodiesel (B100). Diesel Fuel Pure (B0) used as a comparison of the observations results. Exhaust gas emissions were observed using Gas Analyzer to obtain CO, CO2, HC, and smoke opacity. The purpose of this research study is to obtain exhaust gas emissions from the combustion process due to the effect of blending biodiesel-diesel fuel. The increase in biodiesel-diesel blend resulted in the reduction of CO, CO2, and HC at a low rotation of 1000 rpm and 1500 rpm. Smoke opacity not produced in this rotation. Intermediate rotation of 2500 rpm resulting in a reduction of CO, HC, and smoke opacity, but the CO2 had increased. High rotation of 4500 rpm produces CO fluctuating, CO2 was relatively constant, HC fluctuated, and smoke opacity increased

Back muscle functional asymmetry is most common among squash players by their regular unilateral movement while playing. This study analyzed the effect of the body alignment correction program on asymmetry (left-right) developed squash players. Twenty eight asymmetry developed squash players were considered. All of them were male, right-handed and more than four years of experience in playing squash. Electromyography of back muscles (erector spinae and trapezius) and moiré topography of back were statistically compared before and after the twelve week alignment correction program that include various training. Results showed that the scapular inclination was decreased (p < 0.05) and resulting scapular in anatomically straight. To alignment, a decrease was observed in right side inclination and increase in left side inclination, which result in decreased (p < 0.05) left-right asymmetry rate and increased left-right balance. Significant (p < 0.01) decrease in right-side erector spinae muscle activity was observed and identified that erector spinae muscle contributed more on left-right asymmetry than the trapezius muscle. It was witnessed that training program decreased the muscle activity of the stronger side rather than increasing the weaker side. To conclude, the body alignment correction program was effective in reducing stronger side muscle activity and assisting to maintain left-right symmetry

The present paper investigates the effect of completer slip on Peristaltic transport of a Jeffrey fluid in a tapered channel with suction and injection. The mathematical modelling has been carried out under long wavelength and low Reynolds number approximation. The analytical solution for velocity field, pressure gradient, frictional force and stream function in the wave frame of reference are obtained. The pressure rise and frictional force over one wave length are obtained. The effect of different physical parameters on pumping characteristics and frictional forces are discussed graphically. It is observed that pressure rise decreases with increasing permeability parameter and increases with increasing amplitude. It is also observed that for various values of suction parameter k , the pumping curves coincide at a point in the first quadrant due to the suction or injection in the channel. The frictional forces illustrate the opposite behavior compared to pressure rise. The trapping phenomenon for different parameters is presented graphically

Every explored and developed mineral deposit has its own structural features. The mining practice shows that when designing of large-scale blasts, the individual structural features of the blasted rock mass, as a rule, are not considered. In this regard, the estimated parameters of drilling and blasting operations do not meet the requirements for obtaining a given particle size distribution of the blasted rock mass. Despite the high specific consumption of explosives, there is a significant percentage of oversize yield at the Mikhailovsk?? field, which significantly increases costs. This phenomenon is conditioned by complex mining and geological conditions, including the rock stratification. The article considers the effect of the stratification of banded iron formations from the Mikhailovsk?? field on their blasting destruction process. The dependences of the ultimate tensile and compressive strengths on the angle of inclined stratification are identified. The dependences of the change in the particle drift velocity during the stress wave propagation along the strike of stratification and in the direction perpendicular to the layers are determined.

In this paper, an area efficient barrel shifter, which is an important module in the “digital signal processing” and “graphics applications”, is designed using quantumdot cellular automata (QCA) technology. This overview is an approach to optimizing the architecture for barrel shifter, which can be applicable to reduce design delays without significantly increasing the area. We have evaluated the performance of the design by using QCADesigner tool, in terms of complexity, area and latency. According to experimental analysis, the proposed shifter is significantly faster than the previous designed QCA shifter.

One of the important codes, a gray code is normally used to detect correction of error in digital systems. Gray codes use a binary encoding scheme through grouping of the order of the bits and changing one bit of the group. Quantum-dot cellular automata (QCA) is a promising and a future technology for semiconductor transistor based technologies. We propose an extendable QCA binary to gray code converter in this paper. An Exclusive-OR gate is a core element in binary-to-code converter so we used an XOR gate using Nand-Nor-Inverter (NNI) gate which can simplify to logic circuits. The NNI gates are universal gates and can efficiently design XOR gates. A first proposed design is a 2-bit circuit and we extend it to 3-bit and to 4-bit designs. The proposed circuits are compared to previous designs and it shown its efficiency.

Characterization of iron sand magnetic material coated with 2- aminobenzimidazole group modified silica was successfully carried out. The synthesized process was through a sol-gel process using sodium silicate, 2- aminobenzimidazole functional group, and 3-chloropropyltrimethoxysilane as a link agent of silica and functional group. Magnetic material (MM) of iron sand was separated using an external magnet and then washed with distilled water and Hydrogen Fluid (HF) solution of 10%. MM - Silica - Aminobenzimidazole (MMSA) was characterized using Fourier Transform Infrared (FT-IR) spectrophotometer, Xray diffractometer (XRD), and Vibrating Sample Magnetometer (VSM). In addition, the effect of acid pH (1-6) on stability was measured by measuring dissolved Fe ions using Atomic Absorption Spectrophotometer (AAS) and measuring pH Point Zero Charge (pHPZC). The results showed that the synthesized of MMSA material through a sol-gel process was successful. Stability test showed that MMSA was stable under acidic pH solution. Measurements of the pHPZC indicator showed that the surface of the MMSA was negatively charged at the solution pH of <5.39 and positively charged at the pH of the solution > 5.39. Functionalization of the 2-aminobenzimidazole group allows MMSA to interact specifically with metal ions in solution.

Most technology companies in the developed part of the world are probably motivated by the need to change the world or re-invent how things are being done, however, for entrepreneurs in Nigeria, majority seem rather concerned with the ability to satisfy their basic needs such as food, shelter, provision for their family etc. The purpose of the research is to identify specifically what motivates a lot of Nigerian entrepreneurs using Abraham Maslow’s five hierarchy of needs and how it currently relates or affects their company’s current performance which was measured in terms of efficiency, sales volume, level of competitiveness, manpower growth and production volume. The study employed the use of quantitative methods. The study is descriptive in nature using survey research design. The data collected were analysed using descriptive statistics and the hypotheses formulated were tested using linear regression. The tool used for analysing this data was the SPSS version 22.

In addition, physiological needs are found to be significantly related to performance. The recommendation from this research work suggest that collaboration and business network as well as the need for survival would increase entrepreneurial performance.

This paper examines challenges facing SMEs in emerging ICT adoption from diverse actors perspective using data driven thematic analysis approach -similar approach to grounded theory. This study deployed both unstructured and semistructured interviews with the total of 26 interviewees drawn purposefully from Crunch online database in Luton. Data collected from the interviews were analysed to understand both the challenges faced by SMEs and actors that pose such challenges during ICT adoption. The study developed a framework that revealed certain actors that took part in emerging ICT adoption the challenges they pose that impede SMEs from adopting emerging ICT successfully. The finding revealed that Poor knowledge of ICT, and Time are challenges linked to SME managers. Limited ICT support, lack of specialised skills, limited funding, and general support are linked to the government. Dependent and untrustworthy are associated with IT consultants while global solution is linked to IT experts. Commercial interest is linked to IT vendors. The implication is that while some challenges encountered by SMEs originate from them, majority are caused by diverse entities which has constantly limit the extent SMEs embrace new technology

Based on the regression analysis, the research affirms that spatial justice has a direct positive influence on employees behavioural outcomes. However, there was an inverse relationship between temporal justice and employees behavioural outcome. Therefore, Organisations should have functional organisational justice policy framework, especially spatial justice, as it has significant influence on employees behavioural outcomes.

Requirement engineering practice (REP) are developed from requirement engineering processes to guide the engineers in requirement definition. Even though, the practices in agile present a few restrictions and open up several challenges to software industry, they help to address difficulties of conventional models and avert unnecessary cost. However, there are no clear-cut separation of these practices into their individual processes since the practices are closely used and the requirements are ever dynamic. Using Quasi-Gold standard to develop the search strategy and validating the same strategy by Snowballing, this study adapted Kitchenham guidelines to perform a systematic literature review towards identifying the common REP and the extent at which the REP are imbibed in software engineering. Requirement Management is the most popular practice while pre-testing is barely noticed. Eight of their associated challenges are identified and solutions discussed. REP is fully accepted in software engineering going by the annual rise in their discussions but future works is required on the detailed analysis of the root cause of these challenge.

The Analysis of Conventional Commercial Bank Efficiency in Indonesia using Data Envelopment Analysis (DEA) Method as Banking Performance Consideration. Financial institution, bank and non bank, has become one of the most important aspects in the economy of a country, considering bank as financial institution that has an important role as intermediary between the parties with excessive funds and those who need the funds. To apply the principle of sound banking, bank efficiency rating becomes crucial. It is because efficiency represents the performance of a bank as well as factor that must be considered by a bank to act rationally to minimize the risk faced in its operational activities. This study aims to measure the relative efficiency of conventional commercial banks in Indonesia using Data Envelopment Analysis (DEA) methodology based on intermediation approach. Samples of this study are five major banks in Indonesia, namely Mandiri, BRI, BNI, BCA and BTN. DEA is a non-parametric, deterministic methodology for determining the relative efficiency and managerial performance, based on the empirical data of preselected inputs and outputs of decision making units. DEA allows us to compare the relative efficiency of conventional commercial banks by determining the efficient banks as benchmarks for the inefficient ones with input combinations in other banks relative to the benchmarks.

The meat products subsector is one of the most important elements of the product structure of the agro-industrial sector (AIS) of the Russian Federation. Modern economic conditions make it necessary to form, on the basis of the existing meat and food subsector, a real operating meat market, oriented towards meeting the needs of the population for meat and meat products and operating on the basis of economic laws with state participation in regulation. There are several approaches to the study of the essence of this economic mechanism: process, systemic and functional. The logic of the study led the author to the choice of the process approach to study the formation and development of the economic mechanism of inter-branch relations in the subsector. In the structure of the economic mechanism of inter-sectoral relations, the author has substantiated the tools that allow increasing the efficiency of development of the subsector via the process approach. In this regard, the author has proposed a methodological approach to analysis based on inter-sectoral balance which implies studying the contribution of each industry of the agro-industrial sector based on identifying the amount of the increment (addition) of value to each specific value of products that goes into this area from other areas and industries. As a result, new value is created within each specific area and this value is transferred to the related products that are created

In Coal fired thermal power plants, part of energy generated by the power plant is being consumed by its own auxiliary drives. The power consumption by these auxiliary drives for power generation is called as In-house power consumption. Inhouse consumption in coal fired super critical thermal power plants of capacity 500 Megawatt and above with Turbine Driven Boiler Feed pumps should be 5.25% and with Motor driven boiler feed pumps should be 6.00% as per Indian Government norms stated by Central Electricity Regulatory Commission (CERC). But currently it is in the range of 7% (800 MW units) to 10% (500 MW units) of gross generated power at full load conditions in most of the thermal power plants in India. The excessive auxiliaries power consumption is caused by various factors such as part loading of the plant, poor coal quality used as fuel, excessive steam flow, draft loss, internal leakages/ingress in equipment, over loading of drives, distribution network losses, reduced power quality, ageing etc., Here we optimize the loading of one such major auxiliary equipment - primary air fan which is the second major contributor in auxiliary power consumption in a thermal power plant after the cooling water system, by reducing its outlet pressure without compromising on unit performance and boiler efficiency. The thesis also delves into quantizing the operational benefits that will be achieved by measuring the reduction in loading of each primary air fan and estimating the overall benefits that can be attained and tabulating them. Thus optimizing the In-house power consumption of the plant and cost benefits associated with it by operational optimization.

Modern buildings are becoming more complex in technical depth and compartmentalization. The average city dweller also has a complex daily living schedule that sometimes span the entire day with rests taken in between. Existing fire detection technologies have not caught up with the reality of today’s complex buildings and way of living. This paper proposes a fire detection system that integrates three capabilities, namely, detection, communication and suppression. It was designed with residential buildings in mind but can be adapted for top notch performance in commercial and other kinds of buildings. It seeks to address the salient issue of real time communication in the face of an unpredictable daily routine and first line suppression moves at the onset of a fire outbreak that most advanced fire detection systems in complex buildings of today have failed to address. The proposed system uses a controller, which comprises of a microcontroller and a Global System for Mobile Communication modem to co-ordinate the operation of a network of radio frequency transmission and reception capable smoke detectors, alarms, the main source of power to the building and a water pump (sprinkler system).

An important factor in the construction of an information model of a construction object is that various participants in the process of modeling construction objects work with different, sometimes contradictory information obtained at different stages. Based on the concept of life cycle management (life cycle) of construction objects, all information obtained at the previous stages from different participants should describe it as a single information object, around which various processes take place: design, construction, operation, repair and diagnostics of the technical condition, each of which uses and adds to the information model or that information about the object. The article deals with the problem of generalization of construction information on construction objects

Background: The recent recession has placed importance on innovation performance, reduction of costs, and retention of talent. Concurrently, the increase in turnover, negative work place behaviours and frustration have driven an omnipresent interest in ethics and organizational justice. Organisational justice remains topical in Nigeria’s educational quest for long term competitiveness. Unfortunately, most of the existing studies adopted a uni-dimensional approach to organizational justice and primarily focused on performance, ignoring its impact on retention outcome. Methods: Overall, a quantitative approach was adopted in empirical research conducted within selected private universities. One hundred and ninety-seven (197) Information Technology Professionals of selected private universities in Ogun state, Nigeria were involved in the survey and was analysed using measurement and structural models. Results: A quantitative analysis of survey data highlighted the underlying principles necessary to nurture an environment that promotes justice, equity and retention. Organisational justice has various dimensions and each one of them exerts varying degree of impact on the retention of IT professionals in private universities. The study indicated that distributive and interactional justice have positive and significant impact on retention of staff. While that of procedural justice was not accepted as its results were seen to be negatively associated and insignificant too. Conclusion: Organizational justice is very important, playing an important role in influencing employees work attitude and enthusiasm. The role of management is to ensure that organisational justice prevails and jobs are equally distributed along with equal distribution of benefits and rewards. Fair implementation of rules and regulations with no personal or selective favours is essential.

In this paper, the influence of cold rolling with 70% and heat treatment on the microstructure of a 0.22C-1.4Mn-1.6Si TBF steel was investigated. The results show that, when the cold rolling and heat treatment, the microstructures were changed (the finer grain size ferrite was obtained, the solid phases were homogeneously distributing and especially the austenite fraction was 16% after this process), therefore, the mechanical properties were increased. According to this process, the ferrite grain size decreases to less than 6.4µm and the austenite phase reaches to 16%, hence, the high strength and good ductility of this steel were obtained (the strength is up to 800 MPa and the elongation is up to 35%)

Education in modern society has undergone significant changes. Today a big focus is made on students independence, mobility and development of their creative component for quick adaptation in future real professional activities. However, educational institutions are forced to act in conditions of reducing the number of classroom load and changing the role of the teacher (the teacher acts as a mentor and advisor). Therefore, authors talk about the importance of developing a method of instruction. The purpose of the work is to consider development a method of instruction in the professional education of welders. The authors conducted an experiment in which third-year students took part. The experiment was conducted in the first and second semesters of 2017. Students completed the task of welding plates. For the first time, training was conducted only using oral instruction. The results of the control task remained at a rather low level. Only after conducting classes in the second semester with the cumulative use of oral and written briefings, the results were significantly higher. Thus, the authors showed the effectiveness and benefits of additional written briefing.

The emergence of the vulnerability databases around the world are serving the purpose of a double edged sword. The malware researchers, industry members and end users are aware of them to initiate better prevention strategies. The dark world hackers are using them to lure into systems through the points mentioned in the vulnerability databases. Hence, it is highly necessary to predict the malware at the early stage to avoid further loss. The objective of this research work is to predict the malware using the classifiers Logistic Regression, K–Nearest Neighbors (KNN) and Support Vector Machines (SVM). We found that the appropriate use of these classifiers have resulted great improvement in prediction accuracy. Feature selection is also done to further improve the accuracy to 99% with polynomial kernel function

Transcranial Doppler (TCD) ultrasound can be used for detecting asymptomatic circulating cerebral emboli. Asymptomatic embolic signals (ES) can be considered as an important indicator of increased stroke risk. When an ES is reflected by an embolus, these signals have usually larger amplitude than the signals from normal blood flow. Also, they show a transient characteristic. In this study, a number of data mining methods were tested and compared for the classification of embolic signals. A data set containing 100 ES, 100 speckle and 100 artifact were used. The data mining algorithms were compared with each other in order to obtain the best sensitivity in embolic signal detection. Receiver operating curve (ROC) analysis results show that Naive Bayes Tree and Naive Bayes algorithms perform better than the others

Diabetes Mellitus (DM) is a chronical disease that is increasing rapidly. Treatment of DM patients should be patient and careful. For DM patients, continuous medical supervision and dosage regulation is required to help them for living as healthy people. Usually the patients’ age, body mass index, genetic condition, blood and urine test results are used to decide to the appropriate drug doses by doctors. The aim of this study is management of drug dosages for DM patients by using data mining techniques. In this study, ANFIS and Rough Set (RSES) methods are used and compared for obtaining best benchmarking conditions. Input parameters consisted of gender, age, body mass index, genetics, insulin, fast blood glucose, urine, creatinine, cholesterol, triglyceride, HDL cholesterol, LDL cholesterol, uric acid, glucose in urine, acetone, diabetes type and dose of drugs. Dosage planning has been done for Glifix, Diamicron, Glucophage, Humilin_M, Novorapid and Insulin Lantus. As a result of this study, ANFIS give better results than RSES. ANFIS is the most effective data mining technique for dosage planning for Type 2 DM patients.

Additive manufacturing is a promising technology that would replace most of the other processes in future. Metal additive manufacturing is using fusion-based/binder based methods but are relatively expensive. The current research employs frictionsurfacing process as a novel solid-state metal additive manufacturing process producing multi-layered product. The deposited layers are investigated for their metallurgical and mechanical properties. The metallurgical investigations reveal that there is a proper consolidation of material in each layer and the bonding between them is also found to be excellent. The mechanical properties reveal that the hardness of the deposited layers is higher than the substrate.

Quality of Education can interpret as a competitive advantage in printing graduate graduates needed by users through teaching, training and the process of how to educate. In this study what is meant by Campus Innovation is all efforts or breakthroughs, carried out by higher education institutions to find or develop existing situations and conditions to achieve progress and exaggeration of the previous states. The conditions in question include Research, Development, and Diffusion, Organizational / Institutional Development namely the development of higher education to be better, and Configuration, namely the integration of several factors to achieve better/excellent conditions and situations. This research is arranged as a framework used to explain (explanation), detailing the relationship between the Quality of Education on Campus Innovation, by determining the population and sample, the source of the type of data collection, variables, research instruments, and data analysis so that the answers are needed. This research is part of an extensive study with a model of the influence of the quality of education, administration, physical campus on campus innovation and student satisfaction. Based on the results of the direct influence test, it can explain that the quality of education has a positive effect, not significant on-campus innovation. So the hypothesis that quality education has a positive and significant impact on campus innovation is rejected.

The powder mixed-EDM (PMEDM) is a prominent field in precise manufacturing where the material removal operation depends on the electrical erosion mechanism between electrodes in this environment. Prior studies strived to improve the performance of this field, but the obstacles represented by controlling the parameters of this environment created difficulties for the researchers. One of the most important results of this situation is the agglomeration problem between the electrode tool and the workpiece that leads to the collapse of the spark. Thus, the performance of PMEDM environment declines. This study covers the primary reasons for the occurrence of the agglomeration phenomenon in PMEDM. In addition, this study proposes a new methodology to compute the quantity of agglomeration through introducing new hypotheses and procedures. Following from here, the proposed methodology is able to determine the dimensions of the recast layer zone and the density of this zone. Energy Dispersive Spectroscopy (EDS) or Optical Emission Spectrometry (OES) plays an important role in specifying the weight percentage of workpiece elements before and after machining in PMEDM. This study adopted a previous study which observed D2 steel before and after machining in PMEDM by using OES. Furthermore, it applies virtual dimensions of the melting area and the recast layer zone for proving this proposed methodology. Therefore, the total agglomeration for D2 steel is 0.003942529 mg while the active agglomeration of tungsten, carbon, molybdenum, and manganese is 0.001971264 mg. Moreover, the square of the correlation factor (R-sq) and R-sq (adj.) resulting from multiple linear regression analysis for the total agglomeration of D2 steel are 99.36% and 98.97%, respectively. Finally, this methodology presents a new mechanism to specify the performance of PMEDM through adopting the agglomeration ratio as a new criterion. Thus, the agglomeration ratio according to the proposed methodology came up to (50%) which implies that the agglomeration did not exceed the critical stage.

This paper focus on monitoring of surface roughness and cutting forces while machining on two different grade stainless steels under dry and mist conditions. Stainless steels like AISI 304 and AISI 316L are considered for study. Process variables like workpiece speed, tool feed and depth of cut are taken for experimentation on CNC lathe. Responses like surface roughness, power consumption and cutting forces are predicted while machining on the two different stainless grades under dry and mist. Taguchi design of experiments is considered for experimental design. Signal-to-noise ratio of the responses are used for determining individual optimization, while Analysis of Variance is used for knowing significant effect of process variables over the generated responses. This paper shows novelty of using power consumption for calculating cutting forces and also comparisons of two different stainless steel grades simultaneously under dry and mist conditions. In addition, comparison of AISI 304 material with two different diameters is also studied.

The greater challenges of work and personal aspects of life have intensified the work life balance scenario. Employee engagement and retention has emerged as an important as well as critical tool in today’s business. So in order to maintain a equilibrium between personal and professional life, organizations should formulate policies that manage better; any work related stress, tensions or conflict arising at the workplace. The study is based on Literature Review and Secondary data collected from selected papers analyzed and a conceptual framework has been established depicting the reason behind work-life imbalance. This study investigates the factors responsible for work life balance and what are the challenges involved in the manufacturing sector. It was suggested that the employers must consider work life balance programs on the basis of policies they formulate, benefits they provide and services they render. Additionally policies and strategies must be constituted such that it can modify an employee’s perception about his employer and they tend to stay in the organization for a longer period of time. It provides a scope for future direction to various researchers, policy makers and also academicians in this field.

The article discusses the importance of employee engagement for organizational and business performance through the prism of ergonomics. The issues that are discussed in this paper comprise the modest contribution that ergonomics as a discipline has made. The relevance of workplace health and ergonomics work relate with that of participation, safety culture and further implications for participatory ergonomics approaches. Based on recently published conceptual framework that recognises the dynamic and multi-dimensional nature of safety culture, the paper highlights the due significance demanded by ergonomics and that which is equally ignored by top management. The paper concludes by considering the much needed empirical survey on this issue in almost all industries and prompt action being taken to implement it. Also, the paper gives a glimpse of various approaches for an empirical study, within an organisation which is noted as important to the success of ergonomics projects.

This is an analysis of the impact of credits from formal financial institutions on the welfare of farmers in Plateau state Nigeria. The study used survey research design and the instrument of questionnaire to capture input variables, output data and welfare data. Data was partly fitted into the Cobb-Douglas production function for analysis to ascertain the impact of credit on productivity, and welfare data were analyzed through descriptive statistics. It was found that credit available to farmers in Plateau state is inadequate to significantly raise farm productivity and hence the welfare conditions of farmers. It was further found that profitability, Net farm Income and welfare status of borrowers were slightly higher than that of non-borrowers. The study therefore recommends a renewed commitment of both government and formal financial institutions towards improved quality and quantity of credit to farmers so as to boost output and welfare conditions of the farmers in the state.

The study assessed consumers’ demand for local rice in Nigeria. The study specifically described the socioeconomic characteristics of rice consuming households in the study area; assess attributes perception of respondents on local rice consumption in the study area. Data were collected from 150 rural household heads using well-structured questionnaire based on the specific objectives of the study. Data collected were analyzed using descriptive statistics, Tobit regression model, Double Bound Contingent Valuation Method. The double bound logit model estimation of the potential demand for local rice revealed that the potential demands was N559.92. This falls below the price of foreign rice, the substitute for local rice in the study area showing a weak potential demand. The double bound logit model used to test for the determinants of the potential demand among local rice consumers in the study area showed that grain ease of preparation, grain quality and quantity of local rice consumed, positively influenced potential demand for local rice in the study area, while household size, household income, year of formal education and bid amount significantly affect the potential demand for local rice but in a negative direction. The double bound logit model used to test for the determinants of the potential demand among local rice consumers in the study area is statistically significant at 5% level of significance as indicated by the log like-hood test of significance (Wald chi2(16) = 29.80) and Prob > chi2=0.019

The main problem of the research is development of a conceptual framework for investment and innovation security as well as the methodological approach to its assessment, which will allow monitoring and identifying the threats and achieving the desired security state of the national economy. It has been proved that investment and innovation security is a multi-level phenomenon, consisting of the following levels: global, national, corporate and household ones. Investment and innovation security is determined by three components, such as: state security at the external and internal markets, security of enterprises (corporations) and individual households, which requires their balancing. The methodical approach to the integrated assessment of the investment and innovation security level is developed, which involves the development of integral index as the geometric mean of 3 sub-indices, which include single indices under the national, corporate and household level. The results of this methodological approach approbation allowed forming the preconditions for finding ways of growth, forecasting trends and building scenarios for strengthening the investment and economic security of Ukraine

Environmental noise pollution is increased with the increasing of transportation, industrialization, and urbanization. It significantly affecting human health and the environment, especially school children. This study aims in assessing the environmental noise and the suitability of noise instruments for noise monitoring. Noise data (dBA) was collected for three peak hours with the interval of 1-minute by using Class 1 and Class 2 Sound Level Meter (SLM). LAeq for C1 and C2 are 63.20 dBA and 59.00 dBA, respectively. t-Test of two samples assuming unequal variances shows of statistically significant different (p<0.05) among the Classes of SLM. The LAeq of C1 is higher than C2, thus the SLM-C1 is more suitable to be used for monitoring of noise level at the study area. High traffic noise (L10) was noted with the evaluated range of 60.60-76.00 dBA. The background noise (L90) is lower with the calculated values ranged from 50.51-64.44 dBA. The minimum and maximum values of noise level were evaluated with the results of (47.30-53.70 dBA) and (72.00-85.20 dBA), respectively. Noise level at this school area must be mitigated through the planting of suitable trees and enforcement on motor vehicles that passing the school area

This paper proposes a distributed location estimation methodology based on Received Signal Strength (RSS) that consists of two phases, range estimation phase and coordinate estimation phase. In range estimation phase the distance of the unknown node is computed based on the RSS measurements. The effect of channel loss and attenuation in the wireless medium are also considered in the proposed algorithm. The range estimation uses log normal shadowing path loss model and ITU indoor attenuation model. The ranging error is estimated and compromised using onedimensional Kalman filter. The number of iterations in Kalman filter is limited using Cramer Rao Bound (CRB) value. In the second phase the coordinates of the unknown node is estimated by tri-lateration techniques. The accuracy in lateration is improved by min-max algorithm. The RSS value is experimentally obtained in real-time indoor environment using zigbee series 1 RF module. The proposed algorithm is simulated and analyzed in MATLAB version 7. From the simulation results it is found that the proposed localization algorithm performs more efficient in terms of computational cost and accuracy.

This study sought to determine the potential place of Afrikaans and IsiXhosa as indigenous languages to promote communication education in South African Universities. This study examined the approaches and curriculum development of the use of Afrikaans and IsiXhosa to teach journalism trainees in Rhodes and North-West Universities. For the purpose of this study, uses and gratification theory was employed to examine how communication and engineering instructors have adopted Afrikaans and IsiXhosa to teach and train students in the field of engineering and journalism. The method adopted for this study was a mixed method approach combining qualitative content analysis, observation and interviews. Furthermore, a review of previous studies on the adoption of Afrikaans and IsiXhosa for communication and engineering education was examined. The result showed that many of communication and engineering trainers believed that the use of Afrikaans for communication and engineering education aids socio-cultural development among white South Africans. From the findings, it was observed that the idea of integrating Afrikaans and IsiXhosa to teach journalism was premised on promoting local identities. Interestingly, the resultindicated that Rhodes School of Journalism has a course focused on IsiXhosa for Journalism, which is a compulsory course for first year undergraduate students to understand the application of IsiXhosa in journalism practice for creating community based solutions. The study, therefore, recommends that communication educators can adopt indigenous languages for teaching communication and engineering education in Nigeria and other African countries. The adoption of indigenous languages in teaching communication education would facilitate social integration and multicultural development

The paper presents SWOT analysis of Traditional Medicine (TM) in Nigeria using various results in scientific research and author critical opinion on the past, present and future of this important sector of agriculture. The paper is based on the study of many published articles closely connected with the topic. The results emphasized that Nigeria has a long history and culture of TM, conducive climate for the growing of herbs and other materials related to it. Also, TM is available, accessible, acceptable, affordable, widely used, and perceived as effective by the people with virtually no side effects. The weaknesses are: the unverifiable and inexplicable aspects of occultic/witchcraft practices the practitioners lack the skill for correct diagnosis of serious disorders, inadequate coordination of practitioners activities giving room to dubious and unscrupulous elements. Also, opportunities that exists for TMP are existence of a virile Herbs and Leaves Traditional Medicines Practitioners Association of Nigeria, large number of population of TM practitioners with great spread over all ethnic groups coupled with a large Nigerian population of about 170million consumers. The threats: the activities and practices of charlatans, the importation of higher quality TM products and the reality of some herbs are going into extinction. It is concluded that TM occupies a pivotal position in the Nigerian rural health service delivery system which cannot be neglected. Therefore, there is the need to create an enabling environment for the development of traditional medicine and its eventual integration into the health care delivery system of the country

It is mandatory by law for all employers in Nigeria to engage in occupational scheme pension. However, the principles of pension documentation and services are static despite the dynamics of reforms. Most of these problems are caused by the manual approach used by the pension fund administrator. The aim of the pension system is to expedite consumption equalization by making mandatory provision for the future after service. This study analyses the problems faced by many retirees in the Central Region of Nigeria, Kogi State in recent times. The study seeks to develop a secure system for pensioners to assess information on payment of their pension with ease through a computerized pension verification system by adapting the Waterfall model, using tools like the Hypertext Preprocessor Program (PHP) for the programming language which is used in carrying out the web-based pension fund management scheme for effective, efficient, reliable and easy accessibility, and also the use of MYSOL for the database. Based on the findings, it is recommended that the staff pension system developed in this research should be adopted by all states.

This research aims to identify the structure of commodity markets strategic contributor to inflation, patterns of distribution and formation mechanism of market prices of strategic goods that contribute to inflation. The study was conducted in the province of Bangka Belitung, Indonesia by considering some things namely inflation rates of Bangka Belitung, food commodities and the entrance in Bangka Belitung. The study concluded that the structure of the market of all commodities in the object of the research is indicated as a market with high concentration levels. Commodity markets for agriculture, industrial, and livestock were shown to have build oligopoly market structure, while the retailer level is indicated by the market very competitive markets. Distribution patterns tend to vary and do not stick to one line standard, allowing lower-level traders to acquire products from a variety of distribution channels. Costs that dominate almost the entire structure of the commodity cost object of research is the purchase cost of goods and cost of transportation

Retail losses had shrouded the corporate retail stores success. A study on retail store management and its success found that retail stores that were able to control shrinkage and attrition in the medium term, had synergic advantage and were more successful even during difficult times. However, it was found that resource allocation for the control of attrition and shrinkage at the store level is challenges due to resource allocation paradox. A retail store manager has the challenge of choosing either frequent auditing to reduce shrinkage or improving customer service and engagement. The research suggests that the store manager should focus on customer service and instead of shrinkage. This strategy however should be supplemented first by a focus on reducing attrition through conversion of part time employees into full time employees instead of direct recruitment

This paper focused on addressing the effects of operational issues on the stakeholders to a private organisation.

Numerical analysis of fluid flow and heat transfer were performed for cross-flow tube-type heat exchanger in staggered and in-line arrangement. The purpose of this project was to simulate the process of forced convection heat transfer of air over a heated cylindrical pure copper rod using finite element scheme and compared the results with experimentally obtained data. Also, the work was to compare the performance of both staggered and in-line tube bundle configurations. The cross-flow tube-type heat exchangers consist of 25 mm transverse pitch, 18.75 mm longitudinal pitch, 20 cylindrical rods of Ø12.5 mm in a 125 x 125 mm cross section. Finite element simulation was carried out by modeling the working sections of the cross flow heat exchangers. In this, Model geometry was created, meshed, calculated, and postprocessed using FEMLAB 3.0 for ten different air inlet velocities corresponding to experimental data obtained. The simulation results revealed 29.77% and 25.31% deviation in Nusselt number from experimental results for staggered and in-line tube bank respectively

The presentation is a position paper on the interconnections between the education policy, curriculum choices on science, technology, engineering and mathematics and the place of demography. The study is aggregate of thoughts complemented with archival review of existing literature and empirical analysis on admission trends and population growth. It was also firstly presented in one of the several departmental seminars. The study emphasised that demographic trends and growth are the main engine for technological progress. The study portrays demographic trends as crucial engine for technological progress and also works as the drivers of human capital towards achievement of economic prosperity. The result revealed wider gender gap that range from 41.4% to 51.5% in both pre-and postSTEM policy, though it finally stablised at 41.5% in 2009. The study positioned demographers as the conduit for delivery of optimum population or population explosion via assisted fertility technology e.g. in-vitro fertilization (IVF), preimplantation genetic diagnosis, human reproductive cloning, fetal DNA in maternal plasma, and genetic diagnosis). Therefore, while the pursuit of science, technology, engineering and mathematics is crucial for growth, the neglect of the sources of supply of human drivers or the demographic-based pull-and-push factors could engender wobbling and crawling structure of technological advancement. The authors however recommends adequate knowledge of these interplays for plausible appropriate education and technological policies towards the delivery of desire sustainable economic development.

Professional education in Russia was subject to deep reformation. Changing priorities forced educational institutions (according to the new requirements of the Federal State Educational Standards) to look for tools to form graduates of new generation. Education in modern society has undergone significant changes. A large bias today is made on students independence, mobility and their creative component development for quick adaptation in the future real professional activity. Among the main ways which help students to become professionals the authors note the method of conducting classes. Therefore, the purpose of the article is to review methodology for conducting practical training on the subject “Power sources for welding”. The authors conducted an experiment in which third-year students took part. The experiment was conducted in the first semester of 2018. Students completed the task of welding plates. The first group of students was trained using the project method during one semester, the second was taught in a traditional way. The results of the control task in the second group were at a rather low level whereas the first group showed a high percentage of error-free execution of the task. Thus, the authors proved the project method effectiveness and spoke about its benefits in the practical training of students in the course "Power sources for welding."

Charcoal was produced from three different species of wood (Albizia pedicellaris, Tectona grandis and Daniella oliverii) from three different towns in Kwara State, Nigeria. The wood samples and their respective charcoal samples were subjected to thermal and physico-chemical analysis to determine the effect of carbonization on woody biomass as a source of thermochemical energy. The results from the ultimate analysis showed that charcoal had higher percentage composition of carbon (69.4% - 75%) while wood recorded lower percentage of carbon (48.5% to 55%). The proximate analysis showed that charcoal had much lower ash content (1.75% - 7%) compared to wood (4.25% - 19.75%). Charcoal also recorded much lower volatile matter (24.75% - 53%) compared to wood (46% - 80.75%). Heating values were evaluated with charcoals having higher values than wood samples. The highest heating value (HHV) recorded was for Albizia pedicellaris (AP) charcoal from Omu Aran with 30.53 MJ/kg, while the same species from the same location Albizia pedicellaris (AP) Omu Aran recorded the highest HHV for wood sample at 21.65MJ/kg

This study aims to explore the mapping of the development of Indonesian literature using SINTA (Science and Technology Index) database. SINTA is an indexing machine which compiles the entire journals in Indonesia, especially literature journals. This study employed qualitative approach using interpretation data analysis. The methods applied for data analysis were classification, reduction, presentation, and verification. The result of the study revealed that novel studies were the most found in the database totalling 217 entries. On the contrary, drama studies ranked the least with 36 data. It appeared that literary studies of novel dominate more than the ones on fiction, short story, poetry, or drama. In this case, drama ranked the least because it was indeed less preferable in Indonesian literature study.

On October 27, 2016, International Maritime Organization (IMO) announced enforcement of its Revised Annex VI rule, also known as IMO Global Sulphur CAP 2020, to be implemented from January 1, 2020. In an effort to reduce air pollution, especially Sulphur emission, ships will have to use marine fuels with Sulphur content of not more than 0.5%S m/m (Mass by Mass) against current existing limit of 3.5%S m/m for outside the Emission Control Areas (non-ECA) and 0.1%S m/m content for the Emission Control Areas (ECA) will remain as 2015 standard. The regulation implies that ships may use distillates or fuels with less than 0.5% Sulphur (desulphurised HFO), liquefied natural gas (LNG), bio-fuel or continue to use residual fuel with high Sulphur content with an approved exhaust cleaning system installed on board. Both options entail large investment for the ship owners. While scrubber retrofit requires feasibility study with existing engine plant and layout with huge initial capital expenditure for the installation of plant, continuous low Sulphur operation option poses high operational cost due to projected distillate fuel price hike to incorporate with supply and demand in future. On the other hand, LNG and other fuel options for shipping industries fuel demand fulfilment are very lean and immature to date. This paper contains an overview of international shipping emission, particularly Sulphur effects on the environment, and justification on IMO regulatory steps for global sulphur abatement with options for the ship owners to comply.

Automobile companies are spending more on advertising and branding to reach their target customers because of unprecedented hyper intensive competition in the market place. Corporate social responsibility (CSR) is a handy tool that companies use it to enlighten about their good practices with the society. Consumer awareness of a company’s social responsible initiative is a key precondition to induce positive reactions to such activities (Bhattarcharya and Sen, 2004; Du et al., 2010). If consumer awareness is low, the effect of CSR initiatives on purchasing behavior is only of theoretical, not practical, relevance. Due to the low levels of general CSR awareness, previous research considers this concept as a key stumbling block for companies looking to reap the positive benefits of engaging in such activities. This points to a key deficiency in most CSR strategies (i.e., the lack of effective communication).This paper aims to reveal the insights and opinion of general public about the impact of CSR message appeals of automobile companies. This study may also to explore impact of CSR message appeals on brand image of the firms which are campaigning about their social responsible efforts. The research design is descriptive and hypothetical in nature under which the researcher used questionnaire to collect the primary data and secondary data for the literature review. The design of this research is descriptive and hypothetical in nature under which the researcher used questionnaire as an instrument to collect the primary data through the personal interview of survey method and secondary data for the literature review. Convenience sampling technique has been adopted .A well-structured questionnaire is prepared based on the Likert summated 5 point rating scale and category scale. Primary data were collected from 1040 respondents across various automobile showrooms and service centers in Coimbatore, Erode, Tirupur and Namakkal districts in Aug 2018 - Nov 2018 which are important automobile hubs of western Tamilnadu .The collected data is processed by the way of coding, editing and tabulation and analyzed with the help of statistical tools such as percentage method, Mean Score analysis and chisquare test. It is found that people were disagreed that Social consciousness of automobile companies which depicted through the appeals is attracting and has an impact on target audience. Moreover it is clear that the CSR message appeals are not effective enough to enhance brand image of the company. It also revealed that CSR message appeals are not creating high level of impact on audience. At the same time, it achieves high awareness level among audience because of its unique message content

Education in the present day has changed since one decade ago where most educators will use applications and information systems to assist them in the learning and teaching process. This case study discusses what factors influence the success of an institution or organization in terms of implementing E-learning especially for the instructor or teacher concerned. There are five (5 factors) studied where busyness, attitude, curriculum, technology are used and mindset as the reason teachers use Elearning. The method used is a quantitative method using a questionnaire and distributed to the respondents (middle and high school teachers). The results of the analysis state that there is no significant influence from the factor of busyness, and the mindset of success in the implementation of E-learning. Attitude, curriculum and technology have a significant influence. As a result, simultaneous testing of all independent variables has significant results on the success of E-learning implementation. The conclusion of this study is that it can be a recommendation for school leaders to register an internet address domain so that e-learning can be accessed by teachers and students from outside to be able to do the task through Elearning

The transportation, agricultural and power sector of India is largely dependent on fossil fuels that decrease day by day. The government has to import large volumes of fuel from foreign sources to meet the fuel demand for power production, causing a negative impact on the country’s economy. Biodiesel can thus be a destined source to future energy demands. Increasing the usage of biodiesel will also decrease the global problem of environmental pollution, as fossil fuels are considered to be the major source of harmful emissions. In a developing country like India this is not practically feasible to divert the edible oil for production of Biodiesel as the edible oil demand for human consumption is always higher than its domestic production. Under Indian climatic conditions only few plant sources can be considered for biodiesel production which produces non-edible oil in greater quantity and can be cultivated at large scale on non-cropped marginal and wastelands. In this study the available potential of cotton seed oil and rice bran oil biodiesel feed stocks, comparison of cost analysis are discussed. Producing biodiesel from cotton seed oil and rice bran oil feed stocks is greatly possible, cost-effectiveness and availability of biodiesel needs to be carried out to help ensure that biodiesel will be able to fully replace fossil fuel and can thus assist in future energy needs

A computer integrated experimental test set-up is proposed to automate the overload relay testing process using NI myDAQ LabVIEW instrument. G-programming is used to implement the overload relay testing algorithm. Graphical user interface build in LabVIEW supports the testing operator to set the reference current ratings and reference trip time. Test reports data such as trip/non-trip/mid trip time current curves can be monitored and stored for various test cases are stored in the database through LabVIEW.

Abrasive machining methods are used in machining of precision components with stringent size and surface quality constraints, such as medical devices and automotive components. Depending on the work material, grinding wheels made out of different abrasives like, aluminium oxide, CBN or diamond, removes material in the form of micron sized chips. During machining, the abrasives undergo wear and lose their cutting ability. Subsequently, the performance of abrasive tools deteriorates over time without reconditioning of the tool. As a result, controlled removal of abrasives and/or its bonding materials are crucial mechanisms to be addressed in reconditioning of fixed abrasive tools. So, this article reviews the mechanical, electro-physical and chemical material removal mechanisms and their role in self-sharpening of fixed abrasive tools which pave the way for sustainable machining process.

This paper is an attempt to highlight the relationship between social sustainability, economic sustainability, and environmental sustainability and study its influence on quality of life in the back ground of development of smart cities. Using system dynamics methodology, a causal loop was developed from the factors available in the literature and an attempt was made to model and present the system within a working boundary set by the researchers. The model can provide valuable insights to the policy makers by emphasising on the major issues that need to be addressed

The urgency of the study of the theory and practice of the past results not only from the interest in analyzing the situation of the past, but also by the latest social and economic problems in Russia. The article considers the existing characteristics of the specific features of land as a factor of production and agricultural production as a whole, presented in the educational and scientific literature by domestic and foreign scientists. Based on its analysis, upgrades to the existing interpretations of the specific features of land as a factor of production and also agricultural production as the basis of the economic life of society have been proposed. In the theoretical aspect these upgrades will expand the understanding of land as a unique factor of production and, practically, will make it possible to have a clearer description of the specific features of agricultural production. Besides that, attention is drawn to two circumstances that to a certain extent curb the fuller use of the market mechanism in agriculture, namely, the periodic overproduction of agricultural products in a number of developed countries and the presence of so-called “price scissors”. It is noted that the features of agricultural production affect the specifics of agrarian relations, manifested primarily in various forms of ownership and management. The purpose of the article is to clarify the classification of the specific features of land as the main factor of production and agricultural production. The methodological basis of the study is a systematic approach based on the dialectical method of studying interacting objects, which allows classifying and analyzing processes and their results at the macro and micro levels. The incompleteness of the features of land as a factor of production and agricultural production in educational and scientific literature is revealed and their specified classification is proposed. The materials of the work can be used in the training and additional training of specialists in Economics at universities. In theoretical terms, the Characteristics of land features as a factor of production and agricultural production are complemented.

The power conversion efficiency of an isolated ac–dc converter is a dominant factor in the overall efficiency of dc distribution systems. To improve the power continuity and power conversion efficiency of the dc distribution system, a three-phase interleaved fullbridge LLC resonant converter employing a voltage source converter which is fed by Photo Voltaic System and Wind Energy System is proposed as the isolated ac–dc highfrequency-link power-conversion system. The LLC resonant converter has the advantages of high efficiency, high power density, and low cost. They can be operated at no load condition and at resonance for nominal input voltage. The proposed voltage source converter has the capability of boosting the output voltage without increasing the transformer’s turn ratio. Especially, the frequency of the rectifier’s output ripple is six times higher than the switching frequency, thereby reducing the output capacitor and the secondary transformer’s RMS current. However, the tolerance of the converter’s resonant components in each primary stage causes the unbalance problem of output ripple current. It cannot be solved using conventional control techniques since the structure of the three-phase interleaving has the limitations of individual control capability for each converter. To solve the current unbalance problem, a current balancing method is proposed for the output rectifying current

The goals of this thesis is to identify what are the human factors and ergonomic factors that influence the prevention of fatal work accidents in the oil and gas industry with an offshore work environment. Data was taken by distributing questionnaires using the Likert scale to 126 offshore oil and gas workers. The combination of quantitative and qualitative approaches was used in this study. The research data were analyzed by descriptive analysis method and validated using SPSS statistical software ver.16 to ensure the research data had good validity, reliability and accuracy. The results of the study show that the main causes of fatal work accidents in the offshore oil and gas industry are human errors, conditions of workers who are not fit and lack of knowledge. The type of human error that causes it is disobedience, lack of rest or fatigue, and not concentration. Meanwhile, the most ergonomically dangerous type of activity is working at height, lifting, and working in a confined space. From this study it can also be concluded that human factors have a greater influence compared to the effect of ergonomic factors. Based on the results of these studies, it was designed a simple tool to test the level of fitness both physically and mentally from workers in the offshore oil and gas industry to prevent fatal work accidents.

Corrosion on the hull of the ship which is an electrochemical process due to seawater which has very low resistivity. The mechanism of corrosion occurs because of the electrochemical process due to the flow of negative poles to the positive pole. Basically corrosion is the event of the release of electrons from metals (iron or steel) that are in an electrolyte solution such as sea water. Whereas positively charged atoms of metal (Fe+3) will react with hydroxyl (OH-) ions to form rust (ferric hydroxide [Fe(OH)3]). Similar studies in modifying Zn to have anti-corrosive properties have been carried out such as modifying Mn, Fe, Sn, and Ni metals. In this study modified Zn composite materials using Polypropylene waste material and CuO material. Polypropylene is an organic material, low conductivity, and cannot be ionized, ZnO as anti-corrosion particles, CuO as fouling, and PP as a matrix. The initial findings show that it can be made material that has a strong, durable, and environmentally friendly anti-corrosion properties.

Dawn are difficult to be seen when it first rises due to weather conditions and the low intensity of dawn light along with the factor of low visual acuity of the observer. In that case, the detection of the early emergence of dawn by using photometry is very important. The photometric device can detect and measure the dawn luminance, the moment it starts emerging. This study aims to measure the luminance of dawn, LD and the sun depression angle, D? when the dawn began to appear by using a photometer, Sky Quality Meter (SQM) and Digital Single Lens Reflex (DSLR). The result of the measurement using these two tools were compared in terms of the luminance value and the measured value of the sun depression angle. The study was conducted from June to December 2017 in seven locations around Malaysia and Indonesia. The study found that the average value of LD is 19.47 mag arcsec-2 and 20.85 mag arcsec-2 with a DSLR and SQM, respectively. On the other hand, the average value obtained for D? is -17.00° and -16.56° with DSLR and SQM, respectively. We therefore propose that LD is between 19.50 mag arcsec-2 and 20.90 mag arcsec-2 while D? of the dawn is -17.00°.

This paper discuss about the optimized friction factor for aerospace duct of Equipment cooling system of aircraft. Equipment Cooling is provided to maintain assigned temperature conditions in equipment compartment for satisfactory working of Line Replaceable units (LRUs) which are installed inside equipment compartment. Force air cooling is provided to these LRUs using Air Conditioning system (ACS) air. During up gradation programmes of aircraft due to introduction of new LRUs, there remains a requirement of redistribution of flow through complex duct geometries to meet their additional cooling requirements. In the present practice, designers carryout the redistribution of flow of air through these complex ducts using Continuity & Bernoulli’s equation assuming approximate friction factors of head loss which can lead to improper results. In this paper first theoretical calculation for duct with new LRUs is carried out with present practice. After Theoretical calculation, complex duct geometry with calculated diameter is fabricated. The fabricated complex duct is installed on ECS test Rig in similar way as in Aircraft to maintain transient condition. The experimental mass flow rate for each section is measured & recorded. The Experimental calculation of roughness of all pipes in Complex duct geometry is carried out by Profilometer. By using Swamy Jain equation, the friction factor and mass flow rate is calculated. The percentage deviation in mass flow rate in Theoretical, Experimental are calculated by Swamy Jain Equation is compared and deviation is observed. Taking Experimental mass flow rate is main criteria the optimized friction factor formula is derived and mass flow rate based on optimized friction factor is calculated. This optimized friction factor mass flow rate is compared with experimental and very close results obtained i.e. the percentage deviation is very less. This research aims to determine the optimized friction factor through Aerospace ducts. Further, it has yielded optimized friction factor by carrying out theoretical analysis correlated by experimental trials on ECS test rig. Optimized friction factor has helped in estimating the accurate head loss through ducts which has subsequently helped in designing the complex duct geometries

The prime objective of this paper is to investigate the steady, laminar, two dimensional hydromagnetic flows with heat transfer of an incompressible, viscous and electrically conducting fluid over a surface extending with a power-law velocity, entrenched in a porous medium under nonlinear radiation in the presence of a variable magnetic field. The radiative heat flux term is taken to be nonlinear using Rosseland diffusion approximation in general which is valid for small and large temperature difference the plate and the ambient fluid. Governing nonlinear partial differential equations are transformed to nonlinear ordinary differential equations by utilizing suitable similarity transformation. The resulting nonlinear ordinary differential equations for momentum and energy under linear and nonlinear radiation effects are solved numerically employing appropriate numerical schemes. The flow and thermal field sketches are found out and tabulated for various values of controlling factors involved in the problem. The non-dimensional rate of heat transfer and skin friction are also attained for diverse underlying factors and presented graphically.

The floods in Chennai in 2015 raised a question on the disaster resilience of ATMs (1) in India. This papers’ intention was to assess this crisis based on the concept of BCP(2) . Library research was used. The problems of the crisis were based on the newspapers and official reports. Public, private and foreign scheduled commercial banks are covered in the study. The views of the banking industry and the end user have been taken into account. Resources that can aid business continuity have been presented. Additionally, the future of BCP was discussed with regard to the Benchmark Resilience Tool that was developed in New Zealand. The results of this study are: Bank’s action towards a usual circumstance shows its willingness and capability to recover from an ATM malfunction when faced with a disaster. The concept of BCP has not gone beyond IT(3) . A synergistic industry-wide reaction towards disasters is still pending. The focus has been on the Indian scenario and hence the views expressed would be different in the case of developed countries. The technical aspects of an ATM have not been focused. Rather, the focus has been on disaster recovery resources. The observations of certification bodies have not been taken into account, due to lack of literature. This paper is going to add insights into further studies on the empirical level.

Emotional intelligence holds a significant impact on individual development of the manager and their leadership qualities. Doing activities that support EI behaviour illuminates positive effects that can be noted and measured by higher productivity. The impact of emotional intelligence is significant to build positive relations and gaining poignant commitment of employees. When implementing the Emotional Intelligence in Knowledge Management and then a company follows it in its organization the overall yield and profit seems to be increased in an exponential rate and overall it helps in the growth of the company. It also explains Emotional Intelligence along with the Knowledge Management when implemented in the organisation helps the employees developing their own leadership skills and also enhancing the actual skills they posses in the various fields. It also tells us the overall impact of emotional intelligence over the leadership. It also teaches how the Emotional Intelligence and Knowledge Management are correlated to each other and which depend on each. They also tell us the steps they need to be followed to create these Emotionally Intelligent teams and corresponding groups. For more than three decades researchers have postulated that emotional intelligence greatly complements an individual’s ability to work collaboratively within a team setting, cope with stress, and lead others. For example, leaders who are unable to discriminate and self-measure their emotions may not be acquainted with certain cues from their coworkers or subordinates. Likewise, administrators who exhibit deprived management over emotions may permit their emotions to hinder with their level of efficacy as it pertains to leading. For case, when they feel apprehensive, they may shun giving vital speech, or when they feel angry, they may unsuitably lash out at a co-worker. The paper is focusing on the impact of emotional intelligence and knowledge management on leadership qualities.

The consequence of sand and metal moulds on mechanical and microstructural characteristics of Aluminium Silicon Carbide (AlSiC) composite were studied. The composite material was prepared using a liquid-metallurgical technique via stir casting process. The aluminium ingot was melted in a tilting furnace of 5kg for 45 minutes at a temperature of 750ºC. Then 2.5% of silicon carbide (600 grit size) was added to the liquid metal, and to obtain homogeneous dispersion of silicon carbide, two stepwise mixing methods; mechanical and stir processes were applied. Then cast into sand and metal cast moulds respectively which were prepared earlier. The process was repeated for the other percentages of 5%, 7.5% and 10% for silicon carbide. The cast samples were allowed to be solidified and then machined into tensile, hardness and impact specimens according to their specifications. The results of the tests show that for materials which require high impact strength, metal cast process seems to be the best option to be used while for materials that require high hardness resistance, high modulus and high yield strength, the sand cast process should be used.

The use of bandwidth in the network sometimes has not been used optimally in its use. The more devices that access the internet, the greater the bandwidth needed. Upload and download speeds are influenced by the amount of bandwidth used by the network and how effective the bandwidth can be utilized. This internet access speed must be managed properly because it is related to the interests of internet access users so that there are no complaints or even connection failures on other users. One solution so that bandwidth can be utilized more optimally is by doing management on bandwidth so that bandwidth can be utilized optimally. With bandwidth management each client that accesses the internet already has their own bandwidth capacity. Simple Queue is one of the queuing techniques in the bandwidth management system on the proxy router. This queuing technique has ease in its configuration and has the simplest bandwidth distribution. Distribution of bandwidth is regulated statically so that no matter how many users are online, the bandwidth received is also constant, and even tends to decrease.
