During the last few years there has been an ever increasing shortage of critically needed medications, from 2005 to 2010 the number of shortages has tripled (Obama, 2011). The fundamental problem can be identified as an inability in the market to find and reward quality sterile injectable medications. This inability bolsters price competition and incentivize poor quality. The lack of focus on quality frequently leads to needed medication not reaching customers due to quality concerns. In 2011…

(picture of a street in Dover) When you gaze out your window, your typical view is similar to this, a clear blue sky filled with white clouds. When you step outside, you have the privilege of being able to breath in clean air. However, if you were living in India and looking out of a window, this would be much different. (picture of a street in India) Rather than a blue sky, your view would be of a sky turned gray from the excessive amounts of air pollution. Walking out of a building in India,…

important, if it is too deep, the spots on the TLC plates will become submerged and alter the results, too shallow and the solvent will not be able to make it to the desired height on the plate. Since these solvents are generally volatile, a piece of filter paper was added to the jar that had been soaked in the solvent in order to saturate the air inside the sealed jar to prevent evaporation from the plate. The jar was left sealed for about five minutes to ensure air saturation while the TLC…

and then multiplying by 100. Errors did occur during this lab which caused a loss of product. Mostly, the loss of product happen during transfers. On instance of this was during recrystallization. All of the solid particles were not able to be transfer from the flask to the vacuum filter, therefore losing product. The error could have been prevented if more ice cold ethanol was used to transfer the…

disagree with them, with justification. If I had another chance to write this MPQ again, I would like to add some statistics, which would help me back my points up, to increase their credibility. In order to find sources, I used Google with some search filters, and then I filtered them using the RAVEN criteria. One of my sources is a broadcasted TV programme on Discovery Science, which is a very reputable channel for documentaries. The programme interviewed Bruce Gernon, which provides…

The unknown compound we received consisted of white crystal-like particles and was a solid at room temperature. During the smell test, we did not receive any indication of a distinct smell, thus concluding that the compound is ionic. The solubility tests indicated that the compound was soluble in water, NaOH, and HCl and non-soluble in acetone and toluene as shown in Table 1. The compound was soluble in water indicating that the compound is either polar or ionic, but not soluble in toluene or…

Ignorant.Amused.Dumbed-down.Entertain.Blissful.Control. This describes the society in the novel Fahrenheit 451 written by Ray bradbury. The story portray a society without knowledge in order to keep the people ‘’happy it was best to censor what they know’.In fact they have fireman that instead of putting out fires are the ones who starts them to burn the books .So that they can continue to feed the society facts that they don 't have to worry their pretty little heads about . Instead they…

The Chartiers Creek watershed is located in southwestern PA and flows north for 52.4 miles through Allegheny and Washington counties. It has two sections: the upper section that is mostly located in Allegheny county, and the lower section in north/central Washington county. It’s overall size is approximately 227 square miles and it discharges into the Ohio river at McKees Rocks. Chartiers Creek’s water is utilized for agricultural, recreational, and domestic purposes (Dunkle, 2016). The upper…

Bullet damage. Once a bullet is recovered, either from an impact point in a soft wall or pulled out of flesh by a medical examiner or a physician. When a gun is fired, the bullet is not the only thing that comes out of the barrel. Burning powder particles also expectorate and will create a pattern on the object closest to the barrel. With this technology they can retrieve a gun from a suspect and run tests and find out whether it has been shot…

employees at various workplaces. For people who often stay in problematic buildings, these pollutants could be very harmful and cause various unwanted effects. In recent years, researchers have focused on potential health hazards linked with the particles and chemicals that form sick building syndrome (Redlich, 98). The history of Sick Building Syndrome Reports on symptoms of sick building syndrome first…
