The combined effect of promoting Zirconium (Zr) and Tungsten (W) na-nopowders on catalytic properties of pentasil type of zeolites in the conversion processes of natural gas and methanol to aromatic hydrocarbons (ArH) was studied. The addition of Zr to W-containing ZSM-5 leading to enhancement the activity and selectivity of the cat-alyst in the aromatic hydrocarbons formation processes were established. Modifying ZSM-5 with Zr and W nanopowders makes promoting effect on its catalytic properties in the conversion of methanol and natural gas to ArH. Maximum quantity of aromatic hy-drocarbons generated from the conversion of natural gas and methanol in the presence of catalysts was shown, where 1,5 wt.%Zr - 6,0 wt. % W/HZSM-5 and 3,0 wt.% Zr - 6,0wt.% W/HZSM-5, respectively.It is shown that to obtain an effective catalyst for the conversion of natural gas and methanol to aromatic hydrocarbons, a certain combination of weak and strong acid sites are necessary, which is achieved by controlling the amount of modifiers in the catalytic system.

A professional estimate on the MR brain image using Fuzzy K-Means and Particle Swarm Optimization for segmentation

Sri Devi. S ,JECET; September 2017- November 2017; Sec. C; Vol.6. No.4, 646-654.[DOI: 10.24214/jecet.C.6.4.64654.]


The aim of image segmentation is to separate the region of interest from the background and from other objects. Researchers has long been focusing on image segmentation, yielding many automated methods to perform segmentation of different organs in the human body. Nowadays many approaches are in use to segment the medical MR images, among them the Fuzzy K-Means algorithm is widely used. In cluster analysis, groups of similar objects are identified and therefore it helps in discovering distribution of patterns in large data sets. Fuzzy K-means is the most widely used clustering algorithm in real world applications. This paper presents an approach to segment the MRI brain image using Fuzzy K-Means. The accuracy of the Fuzzy K-Means algorithm is not efficient for abnormal brains. To improve the accuracy of segmentation Particle Swarm Optimization technique (PSO) is used and the proposed algorithm is tested in MRI brain image.

A Study on Workaholism of Employees in Garments Industry with Special Reference to Tirupur

Mr.R.D.Suresh and Dr. K. Balanaga Gurunathan, JECET; September 2017- November 2017; Sec. C; Vol.6. No.4, 638-645,[DOI: 10.24214/jecet.C.6.4.63845.]


Work is a part of life; there is no life without work. However, one should enjoy life and work should make it worth living and not make it stressful, boring, monotonous and burdensome. With the development of society, working competition becomes increasingly severe. Employees, the key element in the process of achieving profits, are required or inspired to work in a compulsive way. It is not easy for employees to find a middle ground between work and life. Therefore the term workaholism arises and the preference of wealthy life or pursuit of self- achievement may drive them working more. This will define a modern phenomenon called “workaholism” and discuss its impact on people’s well -being such as work efficiency, family harmony and life satisfaction. This article focuses on the causes of analyzes the workaholism existing in the industry. Employees are very important for any business as they are the backbone of its success. The objectives of the study is to find the various causes for workaholism,to examine the rate of workaholism prevailing in the Industry, to examine various effects due to workaholism,to suggest various measure overcome workaholism.In this study opinion of 150 employees were taken for analysis. The tools used for collecting data were structured questionnaire and unstructured interview. For analysis purpose chi-square, Rank correlation and percentage method has been used. The results revealed that majority of the respondents are workaholics in the organization. High percentage of respondents says that there is significant relationship between employee’s education and habits of starting the work before finalizing all steps in order to avoid these problem managements of various companies in garments industry has to take necessary steps to change working culture. The managements should become highly systematic and employees should understand clearly about their role in the industry. Changing the work culture and being systematic can help to control the issue.

3G and 4G Effects of Mobile Phone Radiations on Testis of Human Body

Mushtaq Ahmed Bhat, JECET; September 2017- November 2017; Sec. C; Vol.6. No.4, 531-537., [DOI: 10.24214/jecet.C.6.4.53137.]


Mobile phones radiations are transmitted from the mobile phone towers using radiofrequency waves. These radiofrequency radiations received and sent by mobile phones in all directions. The mobile phone radiations were exposed to the human body tissues and were penetrated into it. The exposure of mobile phones radiofrequency fields is generally more than a 1000 time higher than their base stations. There are concerns of mobile phone radiofrequency radiations that could cause health problems. These mobile phone radiations are absorbed by human body can cause health problems. If such mobile phone radiations are high enough, so they cause thermal effects on human body. In this paper we find the harmful distances from the mobile phone radiofrequency waves into testis of human body. This study was done at frequencies 2100 MHz and 2300 MHz and radiated power of 1.5 Watts is taken for this study.
