Blackbody radiation is the electro-magnetic radiation emerging from a small hole in a perfectly black box containing electromagnetic radiation at a high temperature. Scientists were interested in setting standards for the electric and thus measured the distribution of the total electromagnetic energy in a black box among the different wavelengths of the light. But not until Max Planck‚ at the turn of the century‚ was a single mathematical formula for the observed distribution of the energy among

types of carbohydrates such as sugars and starches can break down glucose to be used as energy. The movie‚ King Corn‚ is about two best friends and an acre of corn in Iowa. A small ear of corn contains 23 grams of carbohydrates. Corn can be transformed and be used in several different ways. In King Corn‚ they tell us how the acre of corn will be used. They say‚ “10‚000 pounds of corn our acre is likely to produce 32% will be either exported or turned into Ethanol. In neither case ending up in our

Brachytherapy (also known as internal radiation therapy) is the use of radioactive ‘seeds’ to help destroy cancerous cells. It is commonly used as a treatment for cervical‚ prostate‚ breast and skin cancer. How long the treatment will take will depend on where the tumor is and how large it is. Brachytherapy works from the inside of the body by placing the radioactive ‘seeds’ into the body next to the tumor. About 4/10 people with cancer have some type of radiation therapy as their treatment. History

In the past to remove cancerous tumors and small masses‚ surgery was the only option to improve those patients lives; with advances in technology and medicine‚ radiation therapy has become a very likely option for these patients. An option that helps improve their state of life‚ while not having the side effects of

Corns are hyperkeratosis of the skin. This is a thickening of the surface layer of the skin in response to repetitive trauma or pressure. (Footcare) says corns can be hard or soft. Hard corns are found mainly on the top‚ tip‚ or side of toes where constant pressure is applied. Soft corns are usually found between the toes. All corns can be painful‚ but soft corns generally more so. Different types of corns need slightly different treatments. For heloma durum‚ following disinfection of the

Some studies suggest that there is no evidence that cellphone can cause cancer‚ others are saying that there are credible amount of evidence that the use of cell phone cause health complication including cancer.

Acute Radiation Syndrome Acute radiation syndrome which is also sometimes known as radiation sickness or radiation toxicity is an extremely serious illness that occurs when the entire body (or most of it) receives a high dose of penetrating radiation‚ a dose greater than 50 rads‚ in a very short period of time. Studies in animals and humans exposed to radiation have allowed researchers to describe acute radiation syndrome. The most replicative cells are the most sensitive to the acute effects
