HSC Chemistry Assessment task 1 Nuclear Chemistry Research report 1. Distinguish between stable and radioactive isotopes and describe the conditions which a nucleus is unstable. To understand if an element is stable we first must understand what stability is. The stability of the nucleus is directly related to the strength of the forces that hold the nuclear particles together. These protons and neutrons of the nucleus are called nucleons.
Your answer: The precipitin line occurs when the antigen and antibody are in optimal proportions and cross-linking occurs forming an insoluble precipitate. 3. Did you think human serum albumin and bovine serum albumin would have epitopes in common? How well did the results compare with your prediction? Your answer: yes;results showed they have partial identity Activity 3: Indirect Enzyme-Linked Immunosorbent Assay (ELISA) Lab Report 1.
The government stated, “All business and government offices will reopen Monday.” That is a day after the chemical spill. The government worries about the economy dropping financially and is forcing all business to reopen. The government also ordered EPA (Environmental Protection Agency) to evaluate the problem and come up with a solution. Many officials stated that they were only looking to place a “Band-Aid” on the problem. They want to reopen the plant as soon as possible but only temporally fix the problem.
The toxic waste can be managed by treating it well and burying it underground. Also new technology has made it possible to run Nuclear Power plants with thorium. To use thorium the Nuclear Power Plant needs to be driven on the Accelerator Driven System. This system may have a large price tag but it will pay itself back within fifty years or so. Thorium compared to Uranium creates less toxic waste and also unlike Plutonium (the by-product of uranium) the toxic waste created by Thorium will only takes 500 years to be declared safe.
This drug significantly reduced cholesterol from 40 percent to 72 percent when given at two-week intervals. It was also given at four-week intervals but the effects were not nearly as significant. However, “Six patients, all receiving REGN727, stopped the therapy due to adverse events which included headache, injection site reactions, and diarrhea” (Curley, Ann, CNN, 2012). Those side effects would likely scare anyone. That is why the government needs to step in and offer a grant for these companies to dig deeper into their studies and come up with something that has less side effects.
These products included ammunition and rifles. Ever ford motor company participated in this war time production by building boat motors instead of car motors. They also started making premanufactured boats very quickly by using the assembly line method. The ships that the Japanese had destroyed were replaced in no time by new building methods. But the US did not use these weapons on Japan until after WWII.
After two straight years of financial losses in 1994, CEO Ron Allen rolled out a new strategy called “Leadership 7.5.” Allen targeted to reduce Delta’s cost per each available seat mile from more than 10 cents to 7.5 cents, which would match that of major competitor Southwest Airlines (Bryant, 1997). Along with a new company strategy a change followed with Delta’s human resource strategy. This changing policy devastated employee morale and resulted in a decline of customer service, efforts to unionize, and dissatisfaction among personnel. Delta couldn’t keep the past primary policy about human resources so there were several significant changes in Delta’s organization and corporate culture. There are many programs that Delta has built after passing through the cost-cutting reformation in 1997 for getting back its capabilities on customer relationships like rewards and recognition program above and beyond and more.

In 2000 there was a vaccine shortage because quality control issues caused a 6-8 week delay in vaccine delivery. That year supplies were distributed unevenly and prices doubled as a cause of the perceived increase in demand. In 2001 only about two thirds of the produced doses were available at the beginning of the flu season. Then again in 2003 the amount of vaccine supplied did not meet the demand for vaccinations because 4 million doses were destroyed and 87 million were inappropriate for that season’s flu strain. Not taking any action in this case has proven to be a bad decision as was quickly learned in 2004.
