his atrial fibrillation and not due to underlying asthma that had not been noted before. Proair HFA is one of the many trade names for albuterol sulfate. This manufacturer, along with others, now uses HFA (hyrdofluoroalkane) instead of CFC’s as a propellant in their meter dose inhalers since there were concerns about CFC’s contributing to ozone depletion (Swisher, n.d.). Albuterol works by acting as an agonist of β2 adrenergic receptors responsible for bronchodilation, uterine relaxation, and…

Towards the end of World War II in 1945, Americans and Soviets hurried to obtain research done by German scientists during the war. The Americans, in order to bring these new ideas and technology to the US, brought some of the more important German scientists to the US to conduct research for them so that the results would be obtained more rapidly. This operation was highly secretive and was code named Operation Paperclip. The success of the operation, which ran up until 1990, helped move the…

Weeks 7 to 9 Assignment Question 1- The difference between heat and temperature is that heat is measured by temperature. Heat travels from areas of higher temperatures to areas of lower temperatures. Temperature indicates level of heat present. (Hammer & Price, 2001, p. 292). Question 2- The principal means by which heat can be transferred are radiation, conduction, and convection. Radiation is the only way the sun's heat reaches earth. Body with temperature above absolute zero will emit…

smoking. Electronic cigarettes produce a water-based vapor instead of the combustible smoke produced by the tobacco in regular cigarettes. They contain a battery that heats a liquid containing nicotine, a variety of other chemicals, and sometimes propellants or flavorings, and changes this liquid into vapor, which is then inhaled, simulating the feeling of normal smoking (Hanson). The health effects of electronic cigarettes have been debated since e-cigarettes became available, with some saying…

“I am become death, the destroyer of worlds,” Robert J. Oppenheimer once quoted after witnessing the successful first test of the atomic bomb (Brainyquote). What is the atomic bomb? The atomic bomb’s formula was created by a rather surprising force during World War II. Today, numerous nations still use and even improve the atomic bomb. Plus, the future with atomic bombs will be a positive one, although there may be some bumps down in the future. The atomic bomb has a completely different origin…

For my mathematical exploration paper, I have decided to base it on the topic of swimming as it can be affiliated with many mathematical components. However, I was profoundly interested in determining the optimal kicking angle as it caught my recognition. As I further explored this topic, I decided to endeavour to connect a swimmer’s water movement with the quantity of water being pushed around against the flow. As a swimmer myself, I was greatly interested in determining the optimal angle to…

is warming the Earth and is produced from the breath of living beings and the burning of fossil fuels; methane, which comes from swamps and gas emitted by livestock; and chlorofluorocarbons, or CFCs, which were used in refrigerants and aerosol propellants until they were banned for their negative effects on the ozone layer. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment in considered air pollution (Air Pollution…

pass one or the other. And with the KKK, intimidation, murder, and arson was only some of the ways they suppressor blacks rights. But the African Americans had enough of this and soon protested against these injustices. This was only one of the propellants of the civil right movement. After heavy protest, the current president, Lyndon B. Johnson, signed the Voting Act of 1965, in 1965. This law made it illegal to impose voting taxes, literacy tests, and intimidation during elections, local,…

balanced by ethical and economic tethers that keep us here on Earth. Before we delve into the debate of how such a project should be funded, the cost of the transportation of humans and their belongings should be estimated. To start, the CH4/O2 propellant is 14$ a kilogram, and the entire operation will take approximately seven times…

cause, started in the Kneader Room No. 4 and spread from this room and down a corridor. The corridor acted like a funnel channelling the fire to other rooms until the cordite exploded killing five workers. Cordite was manufactured as the smokeless propellant for bullets or shells. The community around his mother, Olive, supported her in her grievance over such a trial and she responded by publishing a card of…
