their ecological and economic functions cease. The most obvious affects from the lack of mangroves would be, the loss of nurseries for fish to grow, increased salinity on the coast and in water supplies, and an increase in coastal damage from natural disasters (Burnett Mary Regional Group for Natural Resource Management Ltd, 2017). Over the course of 200 years approximately 17% of all of Australia’s mangroves have been destroyed and this loss of mangrove habitat has had a direct impact on the…

THE SEVESO DISASTER INTRO The Seveso Disaster was an environmental travesty that occurred on July 10th 1976 due to a chemical manufacturing plant, which released massive amounts of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) into the atmosphere (Lallanilla, 2017). This massive release caused not only environmental implications but health and safety implications as well. Through my research I will deduct what happened at that chemical plant outside of Seveso that caused such a disaster. Further…

Environmental Data Analysis The school that I attended was Page High School, located in Page, Arizona. Page is located in Northern Arizona, established on a mesa on the Arizona-Utah border, and has a population of around seventy five hundred people. Based off the air quality report conducted by the U.S. Environmental Protection Agency (EPA), the two most present toxic chemicals present outside of the school are sulfuric acid and manganese. Sulfuric acid is found most commonly in fertilizer…

Introduction: An electric toothbrush is a toothbrush that makes rapid automatic bristle motions, either back-and-forth oscillation or rotation-oscillation , to provide oral cleaning service, removal dental plaque from the surface of teeth. Electric toothbrush generally powered by rechargeable battery or disposable battery. The functional unit for the electric toothbrush is 3 years per use where 2 times per day. The functional unit for the replaceable brush head is 3 months per use. We will…

Environmentalists blamed Gramacho for the high levels of pollution in Rio’s once immaculate Guanabara Bay, where tons of run-off from the garbage had leaked. No lining on the massive landfill’s floor is the reason leaks of toxic waste drained directly into the water. There was no lining on the massive landfill’s floor to prevent leaks of the toxic waste that was routinely dumped there, and the fetid juices produced by the rot of organic materials, helping make much of the bay unsafe for…

It is advocated in many areas of professional development and practice such as education, management and research, as it encourages practitioners to gain insight into their own professionalism through their experiences (Lucas, 2012). Furthermore, the reflection also enables me to reflect-on-action, reflect-in-action and reflect-for-action. There…

including that all tankers have to have double hulls in the U.S. by 2015 after the Exxon Valdez spill. Global Positioning Systems (GPS) are now helping to prevent ships carrying oil from colliding with other ships and from hitting objects in the water. An increased number of inspections are ensuring that oil wells are safe and following governmental regulations and laws (Zook). These different safety measures can all decrease the likelihood of future oil spills, they cannot guarantee there will…

100 mg of plant material was homogenized in 5ml of 80% ethanol and centrifuged at 8000 rpm for 10min. 100µl of supernatant was diluted up to 1ml with ethanol and 2ml Ninhydrin reagent was added. Mixture was kept for 30 min in hot water bath at 950C. Reaction was terminated in ice and absorbance was taken at 570 nm. Total free amino acid was calculated by plotting standard glycine. Catalase Catalase activity was measured by the method of Aebi, 1974[12]. 0.1 ml supernatant was addedtocuvette…

ABSTRACT Dex-Ibuprofen–polyethylene glycol (PEG) conjugates (PEG-dex-Ibu) were organized and their prospective as a prolonged release method was investigated. PEG-Dex-Ibuprofen conjugates were synthesized as of Ibuprofen and PEG with 4000 Da molecular weights by esterification in the incidence of DCC and DMAP. The PEG-dex-Ibu conjugates were characterized by FT-IR, 1H NMR, and DSC analysis. The solubility revise in aqueous system showed an improvement within the solubility of conjugates. The…

INTRODUCTION The management strategies of dental caries are dependent on the stage at which caries is detected. The incipient carious lesions are characterized by subsurface dissolution due to more fluoride ions in the 50-100 microns of the tooth’s outer surface and less fluoride in subsurface region. Sub surface, non cavitated lesions are amenable to remineralization, thus early detection and diagnosis is of prime importance. 1-3 Traditionally diagnosis of dental caries…
