Water contamination, greenhouse gas emissions, toxic chemicals, earthquakes, and an increased risk of cancer are just a few of the problems associated with fracking. This dangerous extraction technique involves, drilling down into the ground containing natural gas and pumping a mixture of water, sand, and chemicals to dissolve the rock and release the fuel. A process that those in favor of argue, can bring benefits such as, employment, energy independence, reduced C02 emissions and economic…

Benzo(a)pyrene has a chemical formula of C20H12 and is considered a Group 1 Carcinogen by the International Agency for Research and Cancer (IARC) (7, 11). It is composed of a cyclic structure and crystals appear to be pale yellow and needle like from benzene/methanol. It possesses a faint odor and the crystals of Benzo(a)pyrene may be mono-clinic or orthorhombic (4,e). BaP also has a very low solubility in water and to exert its effects, it must be bound to particle matter hence…

2.7. Hippocampal mitochondrial function 2.7.1. Hippocampal mitochondrial isolation After MWM test was finished, all animals were sacrificed and hippocampal tissues were removed. These tissues were minced and homogenized with glass handheld homogenizer. Mitochondria were obtained from the rat's hippocampus by differential centrifugation [38]. In the first centrifugation (at 1500 g, 10 min at 4°C), all of the broken cell debris and nuclei were sedimented. Then the supernatant was centrifuged…

concentrations were deposited on ultrasonically cleaned microscopic glass substrates. The appropriate quantity of cadmium acetate dihydrate {(CH3 COO)2 •Cd•2H2O} was measured to make a 0.05 M solution by dissolving in 50 ml of deionised water and methanol in 1: 1 ration. The required amount of Chromium trichloride hexahydrate (CrCl3 • 6H2O), depending on the desired doping concentrations (0.25 wt. %, 0.50 wt. %, 0.75 wt. %, and 1.0 wt. %) was mixed with precursor solution. The resulting solution…

1. Introduction and background The experiment that will be conducted is the preparation of benzoic acid. Benzoic acid is a carboxylic acid and this has been established in the 16th century. The molecular structure of benzoic acid can be seen in the following figure. Figure 1 – Molecular Structure Benzoic acid is used to prepare esters with the very high boiling points and is used as plasticisers. Plasticisers are compounds that are added to plastics to…

1-[Cyano(4-methoxyphenyl)methyl]cycloalkanol (VF-I) synthesized through the reaction of p-methoxyphenylacetonitrile and cyclohexanone using aq. NaOH and tetrabutylammonium hydrogen sulfate as PTC. NaBH4 and CoCl2 in 2:1 THF: H2O used for the reduction of VF-I to obtain 1-(2-amino-1-(4-methoxyphenyl)ethyl)cyclohexanol (VF-II). Further, venlafaxine derivative of the amino acid -carboxamide (VFCA-I toVII ) synthesized through coupling of N-Phthaloyl amino acid chloride derivative (2a-2g-…

The appearance of the API was done by visual observation Solubility Studies Solubility profiles of Atorvastatin were done by solubility equilibrium method. It is done by stirring an excess of drug in the solvents water, methanol, ethanol isopropyl alcohol for a prolonged period until equilibrium is reached. It is also done in various concentrations of pH buffers. Bulk density:…

According to the House Energy and Commerce Committee, the chemicals used in fracking fluids include over 750 different chemicals. Some are innocuouse (salt, gelatin) while others pose significant human health hazards (methanol, isopropanol and 2-butoxyethanol). About 650 of the 750 chemicals used in fracking operations are known carcinogens, according to the report filed with the U.S. House of Representatives in April 2011. They include toxic chemicals like benzene and tholuene. Returning…

The United states has one of the largest demand for energy in all forms. One common way to get the energy we need is through hydraulic fracking, but it has become more controversial as we know more about it. This paper will discuss what Hydraulic fracking is, what has been the recent controversy around it, and finally what effects the injection of wastewater has on the ground water and seismic geology of the region. Generally speaking, hydraulic fracking is the process of drilling a hole and…

Briefly, gels were placed in fixative (50% methanol and 12% acetic acid) for 1 h, soaked in 50% ethanol for 30 min followed by 30% ethanol for 30 min. The gels were then sensitized for 1 min in 2% solution of sodium sulfite (Na2SO3) followed by rinsing three times with Mili-Q for 20 sec and were stained…
