Chemistry: The Purification of Water

– … The natural purification processes were quite adequate in proving very high pure water quantities except for the desert. Due to the increase in human activity we have often pushed the natural purification beyond their limits. More complex molecules take longer to break down than other. For example, biodegradable substances are broken down easier than nonbiodegradable substances that cannot break down into simpler molecules; which tend to accumulate into the environment. With the overwhelming of natural purification process, cities started using sewage systems to flush sewage in to cesspools, rivers and streams to purify the water….  

Applications of Protein Purification

– Protein purification has a variety of applications in drug delivery, tissue engineering, and biointerface science. Elastin-like polypeptides can undergo protein purification so that a single type of protein can be isolated from a complex mixture. Because of the increased demands of peptide-based biomaterials for drug delivery and tissue engineering, efficient protein purification techniques must be used. Four techniques that will be discussed in this report are: Affinity chromatography, Centrifugation-based Inverse Transition Cycling (ITC), Microfiltration-based Inverse Transition Cycling, and finally protein purification by self-cleaving purification tags….  

Worker Health and Safety in Bangladesh

– Workers Health and Safety Not only do the United States Companies have obligations to workers who produce apparel they market. More importantly, these Americans businesses have authority to correct unlawful violations. In addition, customers rely on merchants’ good will and standing when evaluating the makers of their products. For example, according to Sherman (2013), those global clothing buyers, mainly the United States companies, have a job to execute guaranteeing security of Bangladesh’s apparel workers”….  

The Generation of Ozone for Water Purification in Third World Countries

– The Generation of Ozone for Water Purification in Third World Countries Ozone is the O3 molecule formed through the combination of molecular and atomic oxygen. It can be used to remove iron, pesticides, detergents, color, ammonia and other nitrogen derivatives from water. Ozonation is a process used worldwide to render water potable. Although using ozone for disinfection can be expensive and inconvenient, it has, among others, the advantages of being widely effective, of adding oxygen to the water, and of being sufficient, even in low concentrations (Evans 140)….  

Benefits of a Tax on High Fat Foods, An Outline

– … BODY: I. The “Fat Tax” or tax on food that contains more the 2.5% saturated fat, according to the Herald Sun in 2013. A.
