Space Radiation Too Deadly For Mars Mission by Charles Q. Choi‚ Special to SPACE.com Date: 31 March 2008 Time: 10:00 AM ET Dangerous levels of radiation in space could bar astronauts from a mission to Mars and limit prolonged activity on the moon‚ experts now caution.However‚ more research could reveal ways to handle the risks that radiation poses to space missions.The magnetic field of Earth protects humanity from radiation in space that can damage or kill cells. Once beyond this shield‚ people

Data Analysis Does radiation affect the growth of seeds? If‚ plant seeds are exposed to microwave radiation‚ then the seeds will grow less than how a seed is usually grown. The independent variable was the amount of microwave radiation the seeds receive. The dependent variable was the growth of the plant seeds. Control variables were the amount of water (30 mL at a time)‚ the amount of light (11 hours each day)‚ and the amount of seeds. The control group was the non-microwaved seeds. The experimental

During my childhood instead of playing PlayStation or Xbox I was always outside making new friends‚ riding my bike around and exploring the unknown. That’s what kids do best all ways curious wanting information asking “why you are doing this” or “why do I have to do that”‚ But my parents still brought me up to be respectful‚ Truthful‚ Extremely Helpful and those are only a fraction of what my parents bestowed upon me. In elementary school I was never the bully instead‚ I was the one watching it happen

does natural UVB radiation impact on the marine life? Ultraviolet-B radiation‚ also known as UVB‚ is a type of ultraviolet radiation forming a part of the electromagnetic spectrum (6). It is produced by high temperature surfaces in a continuous spectrum with the primary natural source being the sun. UVB radiation is harmful to living organisms and is only partially absorbed by the ozone layer of lower stratosphere(6). And due to ozone depletion in the recent decades‚ more UVB radiation reaches the surface

that it would have taken at least twenty trees to present a sole square meter of the cityscape. Yucatan central lowland site for most cities was abandoned as a result of the stress of drought and deforestation. Since the cleared land absorbed less radiation from the sun‚ then there was less water that evaporated from the surface thus making the rainfall and cloud scarce. Consequently‚ deforestation exacerbated an already existing drought. Thus deforestation reduced precipitation by 15% thus being responsible

Aim: To observe and describe an example of osmosis. Hypothesis: I predict that the water level will rise as the iodine stained water moves through the cellulose bag due to osmosis. The iodine is there so we can see this happening. Materials: * Dialysis(cellulose) tubing * Thistle funnel * Gas jar * Retort clamp and stand * Rubber bands * 50mL beaker * Iodine/potassium iodine solution * 5% starch solution Method: 1) Fill the gas jar to 3 quarters full with

Doing a complete health assessment or “viewing” the patient as a whole is a vital technique that every nurse should use on a daily basis‚ however I have not practiced this kind of assessment in my working environment. As a nurse in a long term care facility‚ I only do a partial assessment for example when a patient is getting admitted a full body inspection is done: vital signs taken‚ the abdomen is palpitated‚ bowel and breath sounds are auscultated but the cultural and spiritual aspect of the patient
