Processing Petroleum
Not only are the constituents of crude oil separated but they are often treated into different other useful products as well. The entire process begins in the crude oil distillation unit (CDU). All forms of oil refineries possess a CDU which intimates the separation. More separation may be carried out after the CDU too. The basic job of the CDU is to distil various larger constituents in crude oil into smaller more easily processed factions. The CDU for most oil refineries is operated at or

Phramcology ( modules 2 - 3 )
Atenolol, Metaprolol and Propranolol have affects on both the beta 1 and beta 2 adrenergic receptors which makes them favorable in the treatment of uncomplicated hypertension but a patient with asthma and renal impairment should not be given these drugs as they have beta-2 blocking affects too. The beta-2 blocking affects of these drugs could trigger an attack of asthma in an asthmatic patient due to the absence of beta-2 mediated bronchodilatation. Also, in renal impairment these drugs could

Personal Statement (Chemistry Major)
I was always amazed how the human mind was able to construct the synthesis of such complicated compounds. I use my knowledge of drugs in my current job as a caregiver, where one of my tasks is handling medication intake of my patient.I apply chemistry to not only to my job, but also to life in general. Chemistry is hence a pillar in my life and career. Its application in my web programming knowledge has resulted into a website that will enable student generate synthetic approaches to molecules.

Proton exchange membrane fuel cells
This idea was first coined by William T. Grubb of the General Electric Company in 1955. Currently, the most widely employed membrane electrolyte is DuPont’s Nafion. This is because it possesses good chemical and mechanical stability in the challenging proton exchange membrane fuel cell environment. Basically, the physical structure of the proton exchange membrane fuel cell comprises of seven components. These are feeding channels, diffusion layers, catalytic layer in the anode, membrane;

Personal profile about Roger Tsien who is biochemist
After pouring most of his free time towards experiments at his basement laboratory, he was able to win the Westinghouse talent search. His winning entry in the national prize completion was an investigation of how metals bind to thiocyanate (Tsien, 2014). On graduation from Livingston high school, he proceeded to Harvard University. In 1972, he emerged from the university with a bachelor of science in chemistry and physics. Having studied In Harvard University on a national merit scholarship,

Protective equipment
However, the SO2 and SO3 blower continued to feed the system because it was steam powered. This continued for several minutes until a high temperature in the absorbers were noticed by the workers. Unfortunately the temperature values showed by the absorbers were within the safe range of operation of the system (Ness, 2004). At this time, the acid recirculation pumps were restarted showing abnormal pH values, alarming the workers who then shut down the SO2/ SO3 blowers. Investigations showed

Pick a chemical industry or book chapter
About 15% of the worlds production of metallurgical grade silicon is used in semiconductors. The element used for this purpose is highly refined and only forms a fraction of the total production. Silicon’s crystalline nature gives it significant electrical and mechanical advantages (Maluf & Williams 13). The monocrystalline silicon form is used in integrated circuits and in terms of leverage (comparing the quantity produced against its usage) the highly refined form is extremely valuable in

Pharmacokinetics of the seroteninergic anorectic agent, dexfenfluramine.
Of dexfenfluramine is mainly through oral, inhalation routes and lesser extent intravenous infusion in compound called dexfenfluramine hydrochloride (C12H16F3N,HCl)1. Oral administration of compound under the name of ‘redux’ was in capsules enclosing white crystalline powder weighing 15mg. The oral route is favoured due to resistance of dexfenfluramine to acidic media in the stomach. In addition, the hydrophobic nature of the drug is favours diffusion through the gastro intestinal walls. In

Physical Chemistry
The law of multiple proportions that posits that when 2 chemical elements combine to produce more than one likely compound then the proportion of the second element’s mass that joined with a specific mass of the first element will be represented as proportions of whole numbers (Niaz, 2001). The results of this laid the foundation for Dalton’s Atomic Laws. These are made up of five theorems. The first theorem posits that an element, in its unmixed state, is made up of particles referred to

Phosphoric Acid Fuel Cell
This high heat can be turned into a useful source of energy for air conditioners and other thermal energy consuming systems (Onovwiona and Ugursal 389). This property makes the phosphoric acid fuel cell more useful and improves its efficiency to about 80%. The anode electrode in this cell uses a platinum catalyst.

Published synthesis of PD-0332991 (Palbociclib)
The preferred range of temperature is between 60oC to 90oC (the range is important to keep the enzymatic reaction optimum, besides, this range attains the desired speed without altering the expected results), which is maintained for 10 hours. After the process, the intermediate ester formed undergoes the cyclization process through AcOH and heating.This stage involves amino-pyridinyl Coupling. The stage begins with the halogenation of the compound from the previous stage. The halogenation
