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.

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.

Ultrasonic Techniques for hidden corrosion detection
Introduction
Corrosion is one of the serious problem affecting airforce and other aviation industries. It affects the aircraft on its wings, surface, between joints and fasteners. The presences of corrosion underneath the paints of surface and between joints are not easy to be detected. The unnoticed presence of corrosion may cause the aircraft to crash leading to human and money loses. To detect the corrosion present on the metal surface, various method ....etc

Detection of corrosion damage in aircraft wing skin structures is an ongoing NDT challenge. Ultrasonic methods are known and well-accepted techniques, which are relatively simple to carry out in terms of setup, probes and instrumentation and operator training. However, with conventional inspection from the top surface using a transducer at normal incidence (0o to the normal to the surface) producing a visual picture in the form of a C-scan, it is very tie consuming to point-by-point inspects large aircraft wing skin areas. In addition it is too ....etc
