Biodegradation

One is Biodegradation by microorganisms and dilution. The biodegradation for 1080 varies depending on the temperature of the soil, the amount of Bacteria / Micro-organisms present, and the amount of times it rains. In proper conditions, 1080 should be broken down in approximately 1-2 weeks…

Kalyani et al (2009) studied an isolated strain of Pseudomonas sp. SUK1 from the waste disposal sites of local textile industries in India, with the objective of evaluate an ecofriendly textile dyes biodegradation. To isolate the microorganism, they first collected a soil sample from the waste disposal site and inoculated the sample in a nutrient medium with a dye. Then they incubated and plated in agar with dye. The colonies that had a halo of decolorization were selected to be submitted to…

What is Oil Pollution? Oil pollution refers to the release of oil into the ocean. The source of the oil is more often than not due to human activity. The term is usually used to refer to oil pollution in the oceans but can also refer to oil pollution on land. Why is Oil Insoluble in Water? Oil is composed of hydrocarbons. Hydrocarbons are insoluble in water because water is a polar molecule and hydrocarbons are non-polar. The general dissolving rule is that ‘like dissolves in like’, since…

Alberta is a world-leading energy supplier and exporter of heavy oil for the production of fuel. Gasoline is derived from the distillation of heavy oil and while this resource presents as advantageous for the human population, the displacement of used petroleum into the natural environment has been revealed to be the largest contributor to the pollution in and the destruction of aquatic ecosystems (Ramadass et al. 2014). In this case, gasoline is considered a contaminant or an unwanted substance…

The fracking process involves the use of harmful chemicals mixed in with the water used. It is difficult to contain all of the chemicals and contaminated water from spreading to healthy water. This damages the environment and hurts the people around that area. “Streams polluted by the wastewater of fracking contained levels of contaminants that often exceeded federal guidelines for safe drinking water or aquatic health. Soil at the spill sites was contaminated with radium, a naturally occurring…

A landfill is a designated disposal area carefully managed and engineered for the municipal population’s trash. landfills are not “dumps’'. A "dump" is when trash and waste are thrown illegally onto ground or waterway without following proper disposal or recycling regulations and procedures. These kind of "dumps" are completely illegal in the provence of Ontario.(1) What exactly is a landfill? A landfill isn’t Simply a mountain of trash buried in the ground. Landfills have to be carefully…

In order to ensure the safety of users of the Nachsicht device, it will go through a series of rigorous testing to assess its biocompatibility and ability to be sterilized. As the materials used in the Nachsicht, polymethyl-methacrylate (PMMA) and graphene, have been used in other biomedical applications, the host response to the device is highly predictable. Various options for sterilizing the device will be assessed. The tests will be performed in vitro and in vivo before proceeding to…

Annotated Bibliography Li, Yuehui, Kathrin Junge, and Matthias Beller. “Improving the Efficiency Of The Hydrogenation of Carbonates and Carbon Dioxide to Methanol.” Chemcatchem 5.5 (2013): 1072-1074. Academic Search Complete. Web. 4 Feb. 2016. This study states that the recycling of carbon dioxide (CO2) cannot completely reduce the large concentrations of CO2 in the thermosphere, but it is indeed a functional process to produce modern chemicals. However, the process to hydrogenate CO2 with good…

Physical properties of PHB: PHB physical properties similar to polypropylene. However, PHB is perfectly isotactic and does not include any chain branching like, for instance, PE. During processing, it flows easily. It is insoluble in water and soluble in chloroform and other chlorinated hydrocarbons. It exhibits good barrier properties against oxygen and compared to other biopolymers. It possesses better physical properties than polypropylene for food packaging applications. (Chaijamrus & Udpuay…

the cavity. The sponge absorbs the blood and helps to retain the clot formed. This helps in bone healing and regeneration of bone. In the third Group C of 7 patients autogenous tooth bone graft (AutoBT) was used to fill the cavity. Patient’s third molar tooth is extracted and sent to tooth bank to get it grinded in granule form of 400- 800µm. Sterilization of the material is done. After enucleation and curettage this granular form AutoBT is filled in the cavity and then gingival flap is…
