longer than X-rays. UV rays are not visible to humans yet are visible to some insects. UV rays get their name from electromagnetic waves which frequencies are higher than those that humans can identify as the colour violet. Although ultraviolet radiation is invisible to the human eye‚ a lot of people are aware of the effects of UV rays in tanning beds and the sun through sunburn and skin cancer. -Wikipedia The electromagnetic spectrum‚ this picture demonstrates the approximate wave

Toyota’s European Operating Exposure 1. Why do you think Toyota had waited so long to move much of its manufacturing for European sales to Europe? By 2001‚ Toyota’s operating losses in Europe had reached 9.9 billion Yen. Much of this loss was due to Toyota’s operating exposure which was a result of the sliding value of the euro with respect to the Japanese Yen. Between early 1999 and early 2001 (2 year ~ medium-run time horizon)‚ the euro had fallen by approximately 28% with respect to

but on plants. In brief‚ we can say that microwaves are electromagnetic waves with wave length longer than those of terahertz (THz) frequencies‚ but relatively short for radio waves. There are lots of sites contaminated by microwave radiation from cellular radiation‚ power plants and high voltage towers‚ etc….. These affect the plants development‚ which drew our attention towards this project. Our hypothesis is that different doses of microwaves affect plant growth and development. To prove this

Essay preview International Baccalaureate World Literature Analysis - "Exposure" by Wilfred Owen The poem "exposure" by Wilfred Owen is written in Winter of 1917. It portrays the message of the real enemy of the soldiers being the cold and icy conditions. Moreover‚ it provides us with a lively description of the persistent cold and awful conditions during one of the worst winters in the first world war. It shows that most of the soldiers were exposed rather than shot by enemies. The poem portrays

the influence of gamma rays on germination and growth parameters of groundnut revealed suppressive effect compared to non irradiated seed. Groundnut seed (Narayani) were exposed to gamma 60 rays ranging from 0.70 kGy to 2.30 kGy using CO gamma radiation (GC 5000) facility at Quality Control Laboratory‚ Acharya N.G Ranga Agricultural University‚ Rajendranagar‚ Hyderabad during 2010-2011. To find out LD50 dose for the seed and further investigate the influence on germination and seedling parameters

July 15 to September 16‚ 2013. Results showed that seeds treated with 10 kr radiation obtained the highest average height of 128.90 cm with 100 % germination and survival. The seeds treated with 50 kr radiation obtained 0% survival rate and the lowest germination rate (70%). Thus‚ irradiation of 10 kr induces mutation to the corn which will give the highest survival rate and germination of the seed while doses of radiation higher than 10 kr will inhibit its growth and decrease germination. Generally

Most of Europe receives additional radiation and even as far as North America‚ a significant rise in the daily intake of radiation can be noted. A 30% increase in child mortality was registered in May and June of 1986 in New Jersey‚ while southern Germany measured a 70% rise. 3 80-90% of the radiation dose received by the inhabitants of the affected areas was and is internal‚ due to the oral intake of contaminated

A radioisotope is an isotope of an element with different masses‚ whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha‚ beta‚ and gamma rays (Radioactive Isotopes‚ 2017). Radioisotopes have many different uses in the real world‚ but some of the most beneficial uses are in the field of medicine. Technetium‚ more specifically technetium-99m‚ is used in tens of millions of medical diagnostic procedures annually‚ making it the most commonly
