Alpha particle

X-Ray and Neutron Imaging In physics, radiation is described as the transmission or emission of energy in the form of particles such as electrons, neutrons, protons and alpha particles or waves through a medium such as space, air or through a material. Gamma radiation (γ) and electromagnetic radiation, such as x-rays, radio waves heat and visible light are all examples of radiation. One of the main modern physics discoveries was that each unit of a wavelength of any form of wave radiation will…

Prion infectious diseases: History and molecular pathology It is circa 500 BC, and Hippocrates records rare but localised outbreaks of madness within livestock; he observes that the animals’ neurological capabilities rapidly decline after years of apparent normality. When he investigates, he finds that the brains of these animals are ‘very full of dropsy and of an evil odour’. He hypothesises that this disease would be able to spread and infect humans too (McAlister, 2005). To him, this is…

suggested that several different determination laboratories are individually useful for detecting bacterial infection in newborns . thereof include the serum immunoglobulin M, neutrophils and bands represent , serum C -reactive protein orosomucoid ( alpha-acid glycoprotein ) , serum haptoglobin , serum fibrinogen , erythrocyte sedimentation rate , smears buffy - coat and immature neutrophil / total. [ 3-17 ] Bacteria isolated from the blood is the most specific and standard method used to…

Introduction Water has become one of the most prominent natural resources gifted by the Mother Nature, since the early existence of all life forms on the planet Earth. With the vast improvements in society, the living beings, especially human’s consumption of water has advanced from solely for drinking, cleaning and cooking purposes to using water for entertainment and advanced infrastructure (mining) etc. Along with its consumption, there have been numerous issues arising about the ‘influence…

Radioactive pollution is affecting our oceans greatly today. There are numerous reasons why radioactivity and radiation are bad for both you and the environment. Radiation consists of several particles, gamma rays, alpha particles, and other elements that can easily penetrate the human body. When they make their way into your body the biological cells which make up your body are damaged and may decompose, cause fatal cancers, and or genetic defects in future offspring. The more radiation one is…

Uranium is a very heavy metal, which can be used as an abundant source of concentrated energy. The problem is that why do we think nuclear power is good? And why not use wood or coal or something other that nuclear power. Science has identified this issue when they monitored how much resources we use and we have to understand how we won’t run out of resources. This issue affects us because one day we will run out of resources such as coal gas or oil and it will lead to a difficult like which…

acids[1] — arepolyunsaturated fatty acids (PUFAs) with a double bond (C=C) at the third carbon atom from the end of the carbon chain.[2] The fatty acids have two ends, the carboxylic acid (-COOH) end, which is considered the beginning of the chain, thus "alpha", and the methyl (CH3) end, which is considered the "tail" of the chain, thus "omega". The way in which a fatty acid is named is determined by the location of the first double bond, counted from themethyl end, that is, the omega (ω-) or…

On December 12, 2015, the world came together in Paris and for the first time addressed global warming. It was determined that the world’s goal by 2050 would be to keep global temperature increases under 2 degrees Celsius. With such high expectations, the US and other countries around the world need to invest in new power producing technologies in order to phase out the fossil fuel industry. While renewable energy sources such as solar and wind are the best long term solutions, their unreliable,…

being a total of 83 days. The lander itself (Carl Sagan Memorial Station) collected data via the Imager for Mars Pathfinder (IMP) and Atmospheric Structure Instrument/Meteorology Package (ASI/MET) (Nelson). The Sojourner rover was equipped with an Alpha/Proton/X-ray Spectrometer (APXS) and rover imaging cameras (Nelson). The mission was developed in only three years while only spending $265 million (JPL, 2001). According to the Jet Propulsion Laboratory (JPL), Pathfinder captured an…

Science is intuitive. The tallest hill can be the shortest mountain. It is through our intuition that we come to know that the big ones are mountains and the little ones are hills. In some ways, the same is true for science. Science encompasses everything ranging from chemistry to archaeology, microbiology to astronomy. There are so many different aspects to science that it is hard to boil down to one concrete and concise definition. Science is involved with the study of the natural world. This…
