Zellweger Spectrum Disorder is a group of overlapping symptoms and signs that affect many parts of the body. This group of disorders includes Zellweger syndrome (most severe)‚ neonatal adrenoleukodystrophy (intermediate)‚ and infantile Refsum disease (least severe) because these different groups are so similar doctors prefer to just refer to these disorders as severe‚ intermediate‚ and mild. Symptoms that present themselves throughout the levels of severity include weak muscle tone‚ feeding problems

Autism Spectrum Disorder Autism is a brain development disorder that a child is usually born with. The disorder was first described in 1943 (Goldman‚ 2003‚ p.852). It is know to affect about 1 in 1000 people in the U.S and is more common in males than in females (Goldman‚ 2003‚ p.852). The symptoms are very widely ranged. In general‚ there is failure to develop language and communication skills‚ unable to form normal social relation ships‚ and a need to follow a routine. Symptoms Many children

GM; the text book definition of EW is flashed in front of you. “Electronic Warfare is defined as a military action involving the use of electromagnetic energy to determine‚ exploit‚ reduce or prevent hostile use of electromagnetic spectrum and actions which retain friendly use of the electromagnetic spectrum”. 4.

developments have allowed greater use of the electromagnetic spectrum 1. describe electromagnetic waves in terms of their speed in space and their lack of requirement of a medium for propagation In space (a vacuum) electromagnetic waves travel at the speed of light‚ a constant equal to 3.00108ms1. Unlike sound waves‚ electromagnetic waves do not vibrate particles‚ therefore they do not need a medium (substance) to propagate (move). 2. identify the electromagnetic wavebands filtered out by the atmosphere

determines its color. For example‚ when a photon gives off red light‚ you can determine that it does not have a lot of energy because red light is the lowest of visible light on the electromagnetic spectrum. Opposite to that‚ violet light would have the most amount of energy because it is higher up on the electromagnetic spectrum‚ which is because it has shorter

emission of light occurs when an electron moves into a lower energy orbit. Atomic Spectrum The Atomic Spectrum is a series of lines of color produced when light from an excited atom is passed through a prism. It is also known as a line spectrum. Each element has its own unique atomic spectrum. Because of their unique nature‚ atomic spectra are also referred to as the "fingerprints of the elements." The series of lines of color that
