The name of the radiologist comes from radiation‚ which is what radiologist use to look inside the body. (history of radiology) At first they did not know that sometimes radiation can cause injury of even death. To improve their equipment and to stop the new problem the Society of Radiology was born in 1920 (history of radiology) . The Society of Radiology is

Today we use several ways to fight off cancer like Radiation therapy‚ Kimmo therapy‚ or surgery. These are effective ways to fight off cancer‚ but the barrier that comes into play is that some of these affect the body in a negative way and it doesn’t Keep cancer from coming back. I bet you’re wondering what immunotherapy is? How long has it been around? Immunotherapy is the changing of the immune system to find and eliminate foreign cancer cells. There have been early attempts to try and change the

antennas to obtain significant improvement in channel capacity. However‚ the capacity is limited by the correlation of subchannels in non-ideal scattering environments. In this paper‚ we investigate MIMO systems that use antennas with dissimilar radiation patterns to introduce decorrelation‚ hence increasing channel capacity. We develop a ray tracing model that takes into account both the propagation channel and the transmit and receive antenna patterns. Using a computational electromagnetic simulator

To avoid possible harm to the patient‚ it is important that medical tracers do not stay active in the body for long periods. III) The radioisotopes used have short half-lives so that they are quickly eliminated from the body‚ the radiation doses in such procedures are very low and the risks have been carefully examined.

Infrared spectrum is molecular vibrational spectrum. When exposed to infrared radiation‚ sample molecules selectively absorb radiation of specific wavelengths which causes the change of dipole moment of sample molecules. Consequently‚ the vibrational energy levels of sample molecules transfer from ground state to

Chapter 1 Introduction 1.1 Problem It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use‚ you need an efficient way of charging the battery in the phone. But‚ like most people‚ you probably don’t like being dependent on the main supply for charging your cell phone battery or you don’t have the time to recharge your cell phone battery. As technology has advanced and made our phones smaller and easier to use‚ we still have one of the original
