Abstract :The Cerebellar Model Articulation Controller (CMAC) is an influential cerebrum propelled processing model in
numerous pertinent fields. There are different researches done using CMAC in many applications using its
characteristics in easy implementation and good results for example: facial expression recognition, pattern
recognition etc. In this paper we have presented some methods of using CMAC and presents their results.

Synthesis of Faujasite Zeolite (Z) For Adsorption of Cationic Dye from Textile Waste Water. |
Author : *A. G Olaremu, and A.O Adeola |
Abstract | Full Text |
Abstract :The synthesis of Faujasite Zeolite from Locally available Erusu Kaolin clay sourced in Nigeria has been
attempted using standard procedures which have proven sufficient upon slight modifications and reported in
literature. The zeolite was characterized with Scanning Electron Microscopy, Fourier Transformed infrared
spectroscopy (FTIR), X-ray Diffractometer and BET surface area analyzer. Forthwith, Adsorption of the
hazardous cationic dye malachite green (MG) on the synthesized zeolite was investigated. Batch process
variables for the adsorption of MG by Zeolite were determined. The mechanisms involved in the adsorption of
MG by the sorbent were explored using isotherms models. The maximum equilibrium adsorption capacity was
found to be 108.26 mg/g at 30°C. It is noteworthy that the adsorption of MG was reduced (about 45%) at low
pH (4) compared to that at high pH (12). Furthermore, among the other parameters affecting adsorption, a high
MG adsorption capacity (about 54%) was observed at a maximum initial MG dye concentration of 200 mg/L
compared to that at lower initial MG dye concentration (25 mg/L), indicating the dependency of sorption on the
initial adsorbate concentration (CO) in the solution. The MG adsorption data indicate multilayer adsorption
because the data were fit better by the Freundlich model (R2 >0.99) than by the Langmuir model. Surface
diffusion was found to be a possible mechanism for the adsorption of MG by Zeolite. The study shed light on the
potential of synthesized kaolinite derivative “Zeolite” as an efficient sorbent for cationic dye cleanup in
wastewater treatment |

Abstract | Full Text |
Abstract :PURPOSE: The purpose of this paper was to examine the relationship between the tenure of the board and
financial distress of listed firms in Kenya.
DESIGN/METHODOLOGY: The research design used in this study was exploratory design. The study employed
panel regression analysis and simultaneously used pooled regression and random effects on sample size of 57
listed firms in Kenya during the period of 2007-2016.
FINDINGS: The study found that board tenure was found to be negatively and significantly related to financial
performance (ß=-0.091; p<0.01).
THEORETICAL IMPLICATIONS: This study adds value to theory by studying the effect of tenure on
financial performance by updating empirical literature from a developing country.
ORIGINALITY: The paper fills an important gap in academic literature by providing insights into the role of
board tenure in performance of firms particularly in developing economies. In addition, given the increasing
collapsing of companies in developing nations, this paper provides policy makers with evidence on the
implications of board composition on financial distress. |

Failure Study of Reinforced Concrete Buildings of Kathmandu Valley In Gorkha Earthquake 2015 |
Author : Dr Rajan Suwal |
Abstract | Full Text |
Abstract :Nepal lies in earthquake prone zone. There are different fault zones in Nepal. Active fault of in this region causes
several earthquakes in Nepal. In the recent, an earthquake of M7.8 occurred in 77 km NW of Kathmandu (in the
boarder of Gorkha and Lam Jung) at 11:56 on 25 April 2015 with shallow depth of 15 km with maximum Mercalli
Intensity of IX, lasting approximately thirty seconds. Nepal faced continued aftershocks throughout the country
at the intervals of 15–20 minutes, with one shock reaching a magnitude of 6.7 on 26 April at 12:54:08. And
another major earthquake of 7.3 (as per USGS report) occurred in 18 km south-east of Kodari and epicenter is
in boarder of Dolkha and Sindhu pal chowk district at 12.51 on 12 May 2015.
This article is concentrated to study of damages of reinforced concrete buildings only which are in Kathmandu
valley in Gorkha Earthquake 2015. Effect of earthquake in reinforced concrete frame structures in Kathmandu
valley are considered. Height of buildings is taken from two storied to ten storied. |

A Study on Occupational Stress Among Bus Drivers |
Author : Dr. Ashok.J, Harshini.E |
Abstract | Full Text |
Abstract :Professional driving is a very demanding task. According to the recent scientific evidence, Bus drivers tend to
report high levels of occupational stress, burnout and occupational traffic accidents. Health has always been
closely linked with occupation. Occupation related stress among working people is drastically increasing
worldwide. Stress at work place has become an integral part of everyday life and is referred as ‘worldwide
epidemic’ by the World Health Organization. This would have impact on the body and discomfort reflected in
various parts of the body bringing about certain health problems. This study is an attempt to analyze the various
factors that lead to stress among bus drivers and to examine the prevalence of health problems. |
