Environmental degradation of polyethylene-based plastics
The criteria involved in the degradation of polyethylene-based degradable polymer samples have been investigated, with a view to obtaining a clearer mechanism of photo-biodegradation. The compatibility of degradable polymer samples during materials recycling was also studied. Commercial and …

Consequences of Environmental Degradation in Developing Countries
… specifically. I focus on the adverse effects of environmental degradation for two main reasons. On the one hand, it is my impression that the increased vulnerability of less developed countries to adverse environmental degradation needs more attention by scholars (Biermann and Moeller, 2019). On …

Accelerated tests of environmental degradation in composite materials
… in an attempt to speed up the response to these environmental factors. These accelerated cycles were also used in the test program. The results showed visible damage in the form of cracking in both retrials. The PIXA-M material was found to show more damage than the PETI-5. Cracking was confined …

Assessing coupled mechanical behavior and environmental degradation at submicron scales
… deformation and fracture mechanisms, and environmental resistance of materials at submicron scales have been investigated through the combination of nanomechanical testing, high resolution microscopy, diffraction, and electrochemical testing. Nanomechanical techniques were used to isolate …

Interrogating frustration-aggression from environmental degradation in The Niger Delta conflict
… of this thesis lies in understanding why the degradation continued even with the knowledge that their actions threaten the existence of the indigenous oil-bearing host communities (OBHCs) of Bayelsa State (Niger Delta). Irrespective of the fact that the Niger Delta conflict has been a …

A Political Ecology of Copper Production and Environmental Degradation In Zambia
… the relationship between copper production and environmental degradation is intrinsically linked and further hampered by socioeconomic, political and developmental factors.The case of Zambia is used to empirically validate and authenticate how environmental management resulting from copper …

Analyses Of Pultruded Polyester/ E-Glass Composites Subjected To Environmental Degradation
… mechanical characterization that included environmental aging for two different exposure lengths (500 hours and 1000 hours) in five different environments: UV, bleach, hydrochloric acid, distilled water at 125â°f, and room temperature salt water. Three-point flexural bending and short beam …

Assessment of environmental degradation in Northern Ghana: A GIS based participatory approach
… actions interact in a complex way to bring about environmental degradation requires a holistic research approach. This thesis examines the potential application of a GIS based participatory approach in the assessment of environmental degradation in northern Ghana. It is a development of GIS in …

Population pressures, environmental degradation and farmers' adaptive strategies in Nakuru District of Kenya
Despite two decades of government-sponsored efforts to reduce population growth, Kenya's fertility level and rate of natural increase still rank among the highest in the world. As a direct result of population growth, some rural areas, such as those in Nakuru District where this study was centered, …

Integrated environmental degradation model for Fe-Ni-Cr alloys in irradiated aqueous solutions
… the crack advance rate for the given conditions. Environmentally assisted cracking (EAC) is a phenomenon where a combination of aggressive environment, susceptible material, and significant tensile stress result in accelerated degradation, including stress corrosion cracking (SCC), and hydrogen …

Fast Fashion: A Thorough Examination on Human Rights Violations in Bangladesh and Global Environmental Degradation
… industries in human rights violations and environmental degradation. The thesis explores the different implications of fast fashion in a form that focuses on the human right violations workers are enduring and the global effect of such high demand for fast fashion. It uses a mixed …

Characterization and modeling of the effect of environmental degradation on flexural strength of carbon/epoxy composites
… TTS (Time Temperature Superposition) to measure degradation of carbon-fiber/epoxy composite under hygrothermal exposure and applied tensile stress. The hygrothermal conditions capture the synergistic effects of field exposure and extreme temperatures, viz., hot/dry, hot/wet, cold/dry, and …

Environmental Degradation of Aflatoxins and Genetic Diversity of Aspergillus Section Flavi with a Focus on Mozambique
… to 82% of the aflatoxins in contaminated maize. Degradation by these isolates was independent of the presence or absence of aflatoxin biosynthesis cluster genes, in contrast to previous data indicating an association of aflatoxin degradation with an isolates’ ability to produce aflatoxin. This …

Examining the Association of Environmental Degradation and Poor Cardiovascular and/or Respiratory Health Outcomes in a Disadvantaged Community
… was to examine whether residential proximity to environmental air pollution sources, individual-level risk factors (age, gender, and body mass index (BMI)) and number of years at same residence are associated with observed poor cardiovascular and/or respiratory health outcomes in the residents of …

Social aspects of natural resource management in rural Kwazulu
Environmental degradation is widely regarded as an integral part of South Africa's homeland areas. Conventional thinking often blames so-called traditional farming practices, attitudes and values for this situation. In other words, the blame is placed with the residents of the areas and …
