The issue that using mobiles phones can cause cancer has been the topic of longstanding debates. Many studies have been conducted to prove and disprove claims regarding their connection. From time to time, the public is presented with evidence of new found links. The technological advancement of mobile phones has increased exponentially and the same can be really cause cancer. the theory ; Its is suggested that excessive use of mobile phones is associated with an increased risk of certain types of cancer.

This is because mobile phones emit radio frequency energy, which is a form of electromagnetic radiation. They emit electromagnetic waves or signal, which researchers claim to be the reason of a higher cancer risk for users. Another basis of theory is the position of the mobile phone when used. When a person uses his cells phone to call, the antenna use to pick up signal is placed near by brain.

The Great Depression was the worst worldwide economic crisis of the modern industrial era. It began in late 1929 and lasted until after the outbreak of World War II in 1939. From 1929 to 1933, industrial production in U.S fell by nearly 50 percent and unemployment rose from about 4 percent to at least 25 percent. Stock prices fell about 20 percent of their 1929 worth, and well over 30 percent of the nation’s bank failed, wiping out the life savings of depositors.

Previous economic collapses had usually been called “panics”. Therefore, when U.S president at first referred to this new economic crisis as a “depression”, he was trying to avoid the frightening implications associated with the word “panic”. “Depression” implied that the economy had merely taken a brief downturn –a small dip –and was not in the same category as the panics that had hit the same category as the panics that had hit the economy repeatedly in the 1800’s.

Cavity-enhanced direct optical frequency comb spectroscopy is a long and intimidating name for what is basically a medical breath test. You see the string words and you might think this is too complicated for you to understand. Spectroscopy is the study of spectra which is the case is the distribution of colored light. A pulsed laser beam was aimed into the cavity which was design to bounce laser light back and forth. By the time the laser light exited the cavity, it would have traveled several kilometers struck every molecule breathed into the cavity. This allowed comparative analysis of the light frequencies that were absorbed and the amounts. From there, the scientist were able to determine the molecules that were originally present in breath and their concentrations.

Think of the method as a way of sorting through the different molecules in human breath and finding traces of chemicals that could indicate disease.

First there was alcohol breathalyzer. Now there’s a portable drug detector. Instead of laboratory testing that takes a long time to obtain results, a sophisticated device can be used to screen individuals who appear to be under the influence of drugs. The drug detector can measure traces of cocaine, heroin, cannabis, and methamphetamines. It uses a cartridge that has sample gathering saliva, and a measurement chamber that contains magnetic nanoparticles. Using frustrated total internal reflection, the cartridge absorbs the saliva then analyzes it.

The results of the analysis are displayed on an LCD screen with a simple color-coded readout. Look for additional information such as “related links” additional sites,” further reading and the like, it is important that you know where the author got all the information. And even when links are available, it is also important to check that the links work. Although all these may sound too time-consuming, but think evaluating websites as a responsibilities.
