  • This book aims to provide information about Fourier transform to those needing to use infrared spectroscopy, by explaining the fundamental aspects of the Fourier transform, and techniques for analyzing infrared data obtained for a wide number of materials. It summarizes the theory, instrumentation, methodology, techniques and application of FTIR spectroscopy, and improves the performance and quality of FTIR spectrophotometers.

  • For the first time, the detection of DNA sequences, related to HIV (found in AIDS patients), using Methylene Blue (MB) as the redox indicator was performed. The voltametric signals have been investigated on bared chitosan (CS) modified; probe immobilized (DNA single strand) and target-hybridized (DNA double strand) electrodes sequentially by means of Cyclic Voltammetry (CV) and Square Wave Voltammetry (SWV). The response of hybridization between the probe and perfectly complementary, double-base mismatch, single-base mismatch of analyzed targets were clearly identified.

  • What is it? RADAR to detect position of objects. Counter measures 1. ECM ( e.g. chaff cartridges) 2. Non ECM. Avoiding detection and innovating deception . RCS reductions, acoustics, thermal and other EM emissions.How is it achieved. Absorbs radar waves or deflects to other directions. Minimizes heat and other emissions from engine and other spots. Makes difficult to detect except closely.Vehicle shape and structure.Smooth edges maximum radio wave reflectors.

  • ON that summer day the sky over New York was unflecked by clouds, and the air hung motionless, the waves of heat undisturbed. The city was a vast oven where even the sounds of the coiling traffic in its streets seemed heavy and weary under the press of heat that poured down from above. In Washington Square, the urchins of the neighborhood splashed in the fountain, and the usual midday assortment of mothers, tramps and out-of-works lounged listlessly on the hot park benches. As a bowl, the Square was filled by the torrid sun, and the trees and grass drooped...
