C45 steel is considered under the category of the most difficult to cut materials because of hardness (45-55 HRC). Based on the size effect, the low machine's ability may be improved by surface texturing on the rock faces of the uncoated carbide (WC) inserts, using Femto second laser. Dry and Minimum Quantity Lubrication (MQL) cutting experiments were performed with these plain inserts and textured inserts under condition of cutting speed = 80 m/min and 120 m/min, depth of cut = 0.5 mm and feed rate = 0.16 mm/rev. These experiments were performed on different machining time. The comparative evaluation is in terms of cutting forces, roughness, tool wear (flank) and tool tip temperature. Results obtained reveal that average of output parameters is minimum in textured of inserts with MQL condition, as compared to without textured and dry condition

The response of simply supported cross-ply symmetrically composite plates subjected to uniformly distributed load, with lamination [0 90 90 0] discussed. Matlab is used to perform the analysis, depending on classical lamination plate theory. A number of factors such as aspect ratio, side to thickness ratio and modulus ratio and their effect on deflection and stresses of laminated composite plate, subjected to a uniformly distributed load have been studied. The results showed that, the effect of coupling is to increase the deflection to increase the aspect ratio and modulus ratio, and increase the stress with an increase in the side to thickness ratio and modulus ratio.

The air pollution in Indian cities is increasing at an alarming rate. Amongst the world’s 10, most air polluted cities, 6 are from India [1].The air consists of various pollutants like SO2, NO2, PM10, PM2.5, Ozone, CO etc. But PM2.5 is the most dangerous, adversely affecting human health. Air pollution is the 5th highest cause of deaths in India [2]. The study intends to find the particulate matter (PM) concentration levels (PM10 and PM2.5), in Ahmedabad city. 32 areas including commercial, residential, industrial, sensitive etc., across the city, were selected to measure PM10 and PM2.5 concentration, in the month of December 2013.The study found that, almost 44% of these areas had PM10 levels exceeding the permissible limits and 30% of them exceeded the permissible levels for PM2.5, most of them located in the central part of the city. Moreover, certain areas had highly critical PM levels.

With the invention of the internet and new networking technologies, the world has become more interconnected. The concept of network securities is becoming more eminent due to easily acquirable intellectual properties. Network security covers an assortment of computer networks, both public and private, that are utilized as a part of ordinary activity directing exchanges and interchanges among organizations, government offices and people. In this research, discussion paper on the concept of network security as well as various types of network securities is done.

The apparel industry is one of the industries that need to be developed in order to keep abreast of the continuing global developments, in the fashion lines and the types of fabrics used to provide a garment product that satisfies the taste of the consumer. There are a number of specialized programs, for drawing flat models that facilitate the drawing of pattern, including the program AutoCAD, which is known as a computer design program for 2D and 3D designs, issued by the American company Autodesk, and is used in any areas of engineering design, architecture, mechanical engineering and interior design. The research aims to identify the problems faced by students in the flat base pattern, prepare of a simple textbook for the steps of flat base patron and implement of models ready for the basic flat surface of Saudi women. The sample of the research consisted of students of level I and II of Fashion Design Department, where the number of (40) students. The results of the research confirmed that, the effectiveness of the educational book to explain the steps of the basic flat patron, there are statistically significant differences between the average grades of students in the tribal and remote application of the educational book to draw the basic flat platform for the benefit of the post-application.

Human activities have brought out changes on the land surface drastically, in the recent past. Their quest for expansion of habitats has led to changes in land use and land cover patterns. Such studies are important to understand the effect of human interaction with the environment. In the present scenario, though development is essential, it is more important that it should be sustainable. The present study is undertaken in the Hebbal valley of Bangalore, Karnataka to estimate the land use and land cover changes over a period of time, using GIS and Remote sensing technologies. The change in land use and land cover patterns in the study area has been studied from 2001 to 2015. The analysis has been carried out using Survey of India topographical sheets, Satellite imageries and Arc GIS software. The results have shown that the agricultural land extent has been gradually reducing, and has reduced as much as 12.9 percent from the start to end of the study period. At the same time, built-up area extent has shown increases of 7.49 percent and also there is a slight increase in industrial area, in the study area. Simultaneously, a slight reduction in area under water bodies (1.17 percent) has been observed. Furthermore, a negligible decrease of waste lands under barren land/grass land has occurred. The overall results indicate a decrease in agricultural land extent and water, cover year by year.
