A transformer performs many functions such as voltage transformation, isolation, and noise decoupling, and it is an indispensable component in electric power distribution systems. A distribution transformer has consisted of a configuration of iron or steel cores and copper/aluminum coils, with mineral oil serving as both coolant and dielectric medium. Inherent in this type of construction are regulation, significant weight, losses, environmental concerns, and power quality issues. A new kind of distribution transformer is proposed ....etc

1. INTRODUCTION

Silicon has been the heart of the world's technology boom for nearly half a century, but microprocessor manufacturers have all but squeezed the life out of it. The current technology used to make microprocessors will begin to reach its limit around 2006. At that time, chipmakers will have to look to other technologies to cram more transistors onto silicon to create more powerful chips. Many are already looking at extreme-ultraviolet lithography (EUVL) as a way to extend the life of silicon at least un ....etc

CHARACTERISATION AND SORPTION PROPERTIES TO HEAVY METALS (Cu2+, Pb2+) OF CHITOSAN COMPLEXES EXTRACTED FROM COCKROACHES OF RWANDA

ABSTRACT
Cockroaches of Rwanda are one of the most important sources of chitosan. In chitosan extraction from Cockroaches, conditions for deproteinization were: 8% NaOH at 95 ºC for 1 h and demineralization involved treatment with 6.7 % HCl at room temperature. Yield of extract products was ..... Chitin-glucan insoluble complexes in the extracted products were identified by FTIR specus ....etc

ABSTRACT
As leading companies continue to look for innovative ways to reduce costs and increase in production, and labour is one of the main constrain of present time, rail wagon unloading systems are generating more attention. Our project gives a brief overview of unloading coal by BOBRN (Bottom open broad gauge rail) type wagon using track hoppers instead of manual unloading.
