INTRODUCTION TO LASER:-
The word LASER is actually an acronym that stands for
Light Amplification by Stimulated Emission of Radiation .
Based on this principle, a very special kind of light is created,
of a form that doesnâ„¢t exist anywhere in nature. It is one
colour (monochrome) and appears as a tightly bundled,
directed beam. T.H. Maiman, a physicist from California,
USA, succeeded in building the first functioning
laser (ruby laser, with red light) in 1960.

Schizophrenia affects one in a hundred Canadians at some point in their life. This disorder is characterized by auditory hallucinations, delusions, lack of motivation and thought disorder. Antipsychotic drugs improve some of these symptoms, but there is no cure and the cause of schizophrenia is still unknown. Current models suggest that a brain lesion in-utero, in conjunction with neurodegeneration, may result in the symptoms of the disease. These processes may result in abnormal brain function, manifested as changes in brain metabolism.

What is Spectroscopy?
 The study of how 'species' (i.e., atoms, molecules, solutions) react to light. Some studies depend on how much light an atom absorbs. The electromagnetic radiation absorbed, emitted or scattered by the molecule is analyzed. Typically, a beam of radiation from a source such as a laser is passed through a sample, and the radiation exiting the sample is measured. Some, like Raman, depend on a molecule's vibrations in reaction to the light.

Silicon photonics can be defined as the utilization of silicon-based materials for the generation (electrical-to-optical conversion), guidance, control, and detection (optical-to-electrical conversion) of light to communicate information over distance.The most advanced extension of this concept is to have a comprehensive set of optical and electronic functions available to the designer as monolithically integrated building blocks upon a single silicon substrate.Within the range of fibre optic telecommunication wavelength (1.3 µm to 1.6 ....etc

Photonic Computing is digital computing in imitation of conventional electronic computing only using laser light instead of electricity, and holograms instead of silicon computer chips. Photonic comes from photon which is the smallest unit of light just as an electron is the smallest unit of electricity. Photon comes from photo as in Kodak moment! Uninhibited light travels thousands of times faster than electrons in computer chips; therefore it is capable of computing thousands of times faster than electronic computing. Therefore, lig ....etc

ABSTRACT
Imagine a supercomputer no bigger than a human cell. Imagine a four-person, surface-to-orbit spacecraft no larger or more expensive than the family car. Imagine attaining immortality by drinking a medicine. These are just a few products expected from Nanotechnology.
Nanotechnology is molecular manufacturing or, more simply, building things one atom or molecule at a time with programmed nanoscopic robot arms; Nanotechnology proposes the construction of novel molecular devices possessing extraordin ....etc

Abstract
Since the recent demonstration of chip-scale, siliconbased,
photonic devices, silicon photonics provides a viable and
promising platform for modern nonlinear optics. The development
and improvement of such devices are helped considerably by theoretical
predictions based on the solution of the underlying nonlinear
propagation equations. In this paper, we review the approximate
analytical tools that have been developed for analyzing active and
passive silicon waveguides. These analytical tools provide the much
needed phy ....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
