a site upstream from Goomboora Park. This site will be referred to as, Site 1. Measurements from Site 1 will be analysed and compared to water qualities recorded from previous years (2012, 2013, 2014, 2015). Water is a triatomic molecule, with a chemical formula of H20. At a temperature…
Chemical, biological, radiological and nuclear (CBRN) weapons, also referred to as weapons of mass destruction (WMD), continue to pose a significant threat to all living things on earth. WMD are very different from conventional weapons. These weapons can be used in several different ways and the effects can range from environmental destruction, to incapacitating humans or animals, or even killing them. The Department of Defense (DOD) Strategy for Countering Weapons of Mass Destruction is…
The company I have selected to evaluate for its Corporate Social Responsibility (CSR) is Chase. This powerful banking organization has been a cornerstone in the banking world for years and given the already tepid public opinion towards wealthy institutions it is no wonder that Chase has been listed on American 's list of the most despised companies. Recent developments have not aided their case. In the ensuing essay, I will evaluate various aspects of the business as well as explain where this…
Use of microbial platform overexpressing such an ideal O-methyltransferase having flexibility in its catalytic activity over different classes of substrates is of great importance in producing variety of methylated natural products. With this concept, we used the aforementioned natural compounds as substrate for biotransformation reaction. Culture of recombinant E. coli strain was prepared and induced as explained in materials and method. In vivo reaction mixtures analysis of different…
Along the lines of rate laws come half-lives. Such a common topic that comes to mind with half-lives is the decay of radioactive elements, or the time it takes for a certain sample of an element to reach half of its original size. For example, during the Chernobyl power plant incident in 1986, one of the most dangerous elements to begin its decay was Cesium-137 which has a half-life of 30 years. Therefore, people can’t move back to the area because of the deadly amounts of Cesium-137 still…
Adhikary, Sujit. “Vermicompost, the story of organic gold: A review.” Scientific Research, Vol. 3, No. 7. Scientific Research Publishing Inc., [circa 2014], cesantaclara.ucanr.edu/files/235723. In the online article, “Vermicompost, the story of organic gold: A review,” the author dives into the benefits of vermicomposting by explaining the basics of the concept, and then digs deeper into the values and assets of this “organic gold.” The article states how vermicomposting not only gets rid of…
Determining the Chemical Formula of Hydrated Copper (Ⅱ) Sulfate Using the Empirical Formula Introduction In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined. In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water. CuSO₄・XH₂O The empirical formula can be determined if the moles of the compared substances…
This experiment was performed in order to demonstrate the principles of nitration through electrophilic aromatic substitution. It also examined the effects of bromine on an aromatic ring, ortho-para vs. meso directing. The second experiment was performed to compare the reaction rates of electrophilic aromatic bromination with different arenes. Data and Results In the gas chromatogram, there are two large peaks. The first peak at 0.653 minutes with an area of 133,352 uV per second, 31.95% of…
We first evaluated whether Honokiol treatment was toxic to the APP-CHO cell line. Cells were treated with various concentrations of Honokiol (0.5 μM, 1 μM, 2 μM, 5 μM, 10 μM and 20 μM) for 24 h and cell survival was determined by Prestoblue® assay (Fig.1A). As shown in Fig.1A, when exposed to Honokiol concentrations of 10 μM or lower, the viability of APP-CHO cells was the same as untreated control cells. However, a significant decrease in cell viability was observed with 20 μM Honokiol…
Introduction Enzymes are specialized proteins that act as catalysts. Enzymes are a key part of many biological processes because they are capable of lowering the activation energy of a chemical reaction. By lowering the activation energy enzymes are able to speed up reactions allowing for multiple chemical processes to occur at a faster rate in many living organisms. Enzymes work by binding to specific molecules called substrates. The enzyme observed in this experiment was amylase and its…
