Abstract:
Imagine a device no bigger than a credit card that could extract your DNA from a drop of blood and map your entire genetic code while you wait. Within a short period of time the proneness to any illness or disease could be mapped and studied. This is not a snippet from a fiction movie. Biologists and engineers will have ONE working in just a few years, because the tool that makes it possible, a genetic microarray known as the DNA chip, already exists. Able to scrutinize tens of thousands of genes at once, the DNA chip's astonishin ....etc

CHAPTER 1
INTRODUCTION
In certain application fields where image processing is involved, the use of spectral information in the visible (VIS) and near infrared (NIR) range is critical. The systems for spectral measuring can be classified according to their spectral resolution or their spatial resolution. Narrowband hyper spectral systems are usually based on point spectrometers or linear spectrometers. These systems can measure many precise narrow spectral bands of a point light source or a line source, in the VIS and NIR ranges and beyond. O ....etc

ABSTRACT
This paper describes the application of two relatively new diagnostic techniques for the determination of insulation condition in aged transformers. The techniques are (a) measurements of interfacial polarization spectra by a DC method and (b) measurements of molecular weight and its distribution by gel permeation chromatography. Several other electrical properties of the cellulose polymer were also investigated. Samples were obtained from a retired power transformer and they were ana ....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
