Emission spectrum

Cap and Trade Cap and trade is a system in which economically and an environmentally approach to control the emission of green house gases. Cap and trade is a market based approach to control pollution which was adopted by many countries, states, and groups of companies. The cap sets a limit on emissions, which is lowered over time to reduce the amount of pollutants released into the atmosphere. The trade creates a market for carbon allowances, helping companies to come up with different ideas…

Spectroscopy is the study of objects, which is represented on the spectrum of color they radiate. An interaction of electromagnetic radiation with matter. Spectroscopy involves the process of absorption, emission, or scattering of electromagnetic radiation by either ions, atoms, or molecules. The process of absorption involves when light is absorbed by electrons that jump to higher energy levels. On the other hand, emission spectra are established when the electrons from high energy levels give…

equation to find sin() (Sin(x)= opposite/hypotenuse). The final goal of this part is to be able to accurately and effectively calculate the value of d, by using the initial equation1. Part B’s objectives focus on the fundamental understanding of atomic emission and the Balmer Series. The objectives for this section include the proper recording…

renewable energy. The best and most efficient way to lower carbon dioxide levels would be to switch from gasoline powered cars to electric or hybrid cars.Battery electric vehicles or BEV run on battery power instead of gasoline which makes them have zero emission. The founder of Tesla, Elon Musk, has created the Model S that runs completely on battery power that cover a range of about 300 miles per charge. Another option would be plugin hybrid electric vehicles or PHEV because the gasoline in…

state - The reason as to why they are in an excited state is due to the extra energy the photons are producing - As time passes by, the molecules slowly go back to their original state by giving off photons which we see as the glow of an object (emission of photons during relaxation) Have you noticed that most of the glow-in-the-dark objects that we have are mainly green? Why is that? - Scientifically, when making an object glow using phosphorescence, the chemical phosphor use is zinc…

Spectrophotometry is a method in which organic and inorganic substances are identified or characterized by the use of electromagnetic radiation. Electromagnetic radiation not only includes light (or photons), but thermal energy as well. While the electromagnetic spectrum consists of wavelengths between gamma radiation and the Far IR, most spectrophotometric methods rely on the UV and visible region. In order to use spectrophotometric methods, the sample being analyzed must be able to absorb the…

How threatening it might sound, nuclear medicine is a very common type of treatment, as “On average, one in every two Australians can expect at some stage of his or her life to undergo a nuclear medicine procedure,” (Australian Nuclear Science and Technology Organization). It may come as a surprise, but these include Nuclear Imaging such as MRI (Magnetic Resonance Imaging), Pet scans, CT (Computerized Tomography) CAT (Computerized Axial Tomography). And no it is not A green liquid in a capsule…

Early brain imaging studies of musical imagery used PET (positron emission tomogra- phy), which has now been almost completely replaced by fMRI. PET and fMRI each have their pros and cons as methods for functional brain imaging. PET works by com- bining several tricks. Typically, subjects are injected with 2-deoxyglucose, a modified form of sugar that is transported through the bloodstream to cells just like glucose, but cannot be metabolized. As a result, 2-deoxyglucose builds up rapidly in…

While on the ice, hockey players can take a hit when they least expect it. They can be blind sided from behind or tripped with a stick at any given time. In the case of Paige Decker, the reckless behavior of another player can change not only the course of the game, but the course of a player 's life. Paige was a successful hockey player on the Yale women’s hockey team. She was in the prime of her game, and a member of the ECAC All-Academic team. She was preparing to graduate from a prestigious…

is to review, in an unbiased way of brain imaging technologies in investigating the relationship between biology and behaviour. Brain imaging technologies, with their advantages and disadvantages: PET scan/Positron Emission Tomography scan What it is: A PET scan, or Positron Emission Tomography scan is a scan that detects positrons that are emitted from radioactive materials, and is used to scan bodies containing a radioactive tracer/radiotracer/radiopharmaceutical/radionuclide is either…
