Objective The objective of this lab is broken into two parts. The first is to recognize the principles of flame ionization and atomic spectra. The second is to observe and thus further understand the line spectra for multiple elements or molecules as well as determine the correlation between emission spectra and atomic structure. Experimental Procedure Procedure 1: Observation of Line Spectra by Discharge Tubes Six discharge lamps were selected – argon‚ carbon dioxide‚ helium‚ hydrogen‚ iodine

2G Spectrum Scam The Rs 1‚76‚000 crore loot in telecom by the UPA govt 1) What is spectrum? What is its relation with mobile phone services? Spectrum is airwaves. Each operator is assigned a set of frequencies. In normal basic telephone service‚ a pair of wires is used for communication. But in case of mobile/wireless communications‚ airwaves are used instead of wires. These spectrum/airwaves are licensed by the Government. It is allocated in Mega Hertz (MHz) in telecom licenses. 4.2 MHz is given

Autistic spectrum disorder‚ otherwise known as autism‚ is a complex disorder of the central nervous system and a developmental disability that comes from a neurological disorder that affects the normal functioning of the brain. (Dowshen‚ 2008). It is not something one can catch or pass along to someone else. It makes interacting with other people incredibly difficult. Autism was first identified in 1943 by Dr. Leo Kanner of Johns Hopkins Hospital. Autism spectrum disorder can usually be reliably

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
