Generally, the headquarters are in the home country, and the headquarters has full ownership and control over company. Advantages of MNC’s include level of investment increases, more income and…

The PANI nanorods recorded higher rate of dye decolorization of 99% within 8min compared with PANI nanoparticles that recorded the same percentage decolorization within 16min. Keywords: Polyaniline, morphology, nanostructure, CO2 polymerization, wastewater treatment, dye removal.…

ABSTRACT: Terpolymer / kaolinite microcomposites were synthesized by 2:2:1 molar ratio of aniline, anthranilic acid and o-phenylenediamine monomers, respectively using various percentages of kaolinite clay via modified in situ oxidative ter-polymerization. The results were confirmed by FT-IR and UV-Vis absorption spectra of terpolymers / kaolinite composites. The thermal behaviour of the terpolymer and composites was studied. Terpolymers / kaolinite composites were thermally more stable than…

people are concerned about what bacteria can be getting into their water.The spill tore a 25-foot-wide gash in the side of the farm’s 8-acre waste lagoon, an above-ground earthen enclosure built to hold 30 million gallons of hog waste. A wall of wastewater washed out part of a driveway and cut large swaths across fields and woods. Researches are trying to create a better way to stop the bacteria from getting into the local water around the hog factory. The researchers have come up with several…

Wetlands are natural occurring ecosystems. Wetlands improve water quality through the filtration of polluted water from point and non-point sources. Point sources of water pollution, industrial wastes and pipes, cause pollution in contingency with non-point sources such as storm-water and agricultural runoff from pesticides, fertilizer, and manure. Water pollution induces water eutrophication through oxygen depletion, temperature increase and imbalanced pH. Eutrophication of bodies of water…

fish. One impact that has been noted is that fish are turning out to be more female like in view of the hormonal medications found in the water (Berg, 2008). While steps have been taken by the administration to convey models to water treatment and wastewater treatment plants a portion of the contaminants saturate the water supply after it has been sifted. The US Environmental Protection Agency (EPA) has issued guidelines for drinking water with strategies like the Safe Drinking Water Act of…

March 26, 2018 To: Ellen Cohen, Mayor Pro-Tem of Houston City Council From: Janet Asante, Chief Environmental Science officer for the Houston Health Department Re: Urban Houston Communities Suffering from Pollution after Hurricane Harvey Background and History: Hurricane Harvey is the first hurricane to hit the Texas coast since Ike in 2008 and the first major hurricane to hit Texas since Brett in 1999. Houston, which was founded on the banks of the Buffalo Bayou in 1836 and rises barely above…

Aquatic macrophytes functions in several ways in the aquatic environment, they are critical to Niger Delta inland waters because they enhance the physical structure of the habitat which provides living space for small animals and play an important role in fisheries production. Macrophytes play a vital role in the aquatic environment and the lives of rural communities but unfortunately very little effort is being directed towards the conservation of these resources and these macrophytes can get…

Storm water is a large quantity of rain fall or excess water from melted snow or ice. Storm water runoff is the melted ice or snow that flows into the nearest river, creek, lake or ocean instead of being infiltrated into the ground. Storm water management is to lessen as much polluted runoff water flowing back into the nearest body of water. Within in this paper, methods for managing storm water will be issued. Stormwater runoff has been documented to increase flooding which reduces ground water…

Angella Brown HCA 350: Research Paper - China and Philippines Charter Oak State College China This research paper outlines the differences amongst China and the Philippines. Therefore, I will discuss the demographics in these two countries or the factors that may impact the health of the countries. The impacts affecting the health of China and Philippines are caused from environmental, political, and economic issues. Within my research I found many similarity as well as difference. We are…
