On the other hand‚ the usage of cell phone had become addictive to people of all around the world and the abuse of prolongated hours on the cell phones can cause health hazard. Cell phones work under a non-ionizing radiation bases. But there is still a concern of how much cell phone usage a person can endure without any harmful reaction to them. I myself believe that cell phones may cause a reduction of blood cell count‚ but I do not believe that cell phones causes

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

HIV/AIDS and Its Effects on Economic Growth Taywanna Drayton ECO 204 Instructor Stephanie Webb August 16‚ 2010 HIV/AIDS and Its Effects on Economic Growth For most developing countries‚ the main source of progress is through industry and domestic saving. In order for industry to be a viable source of progress‚ the country must have a large‚ productive workforce. Certain elements may stymie growth‚ leading to a slow down in development and‚ by proxy‚ a stalled economy. For developing

Plants‚ also called green plants (Viridiplantae in Latin)‚ are living organisms of the kingdom Plantae including such multicellular groups as flowering plants‚ conifers‚ ferns and mosses‚ as well as‚ depending on definition‚ the green algae‚ but not red or brown seaweeds like kelp‚ nor fungi or bacteria. Green plants have cell walls with cellulose and characteristically obtain most of their energy from sunlight via photosynthesis using chlorophyll contained in chloroplasts‚ which gives them their

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

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. According to the article “Dangers of today technology” Recent research shows that cellular phones can cause health complication‚ including cancer. “Heavy long exposure to cell phone radiation increases risks for certain type of cancer

Effect of Substrate Choice On Growth Of Mealworms Abstract: The experiment is designed to show which substrate A or B will better nourish a mealworm. A mealworm was placed in each substrate for a period of seven days and the change in mass from Day 1 to Day 7 was compared. The data was compiled and statistically analyzed. The experiment failed to reject the null hypotheses that there would be no difference in the two substrates regarding meal worm growth

Conduction‚ Convection‚ and Radiation Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers‚ Conduction‚ Convection‚ and Radiation. The first kind of heat transfer‚ conduction‚ is heat transferring through direct contact of materials. This would be the same thing as a pan on the stove. The heat from the stove touches the pan directly‚ therefore making the pan hot. The next type of heat transfer is convection
