The Production of Uneven Geographies: Environmental Hazard Exposure and Socioeconomic Inequality
This thesis examines how environmental, economic and digital change are reshaping the geographies of inequality. Adopting an interdisciplinary approach that integrates economic geography, environmental economics and critical urban studies, it argues how space is an active dimension that structures …

Solar-Powered Critical Cooling: A Theoretical Feasibility Study for Human Thermal Regulation
Over the last 50 years, the leading global environmental hazard has not been hurricanes, lightning, tornadoes, floods, or earthquakes, but extreme heat events. With climate models projecting an increase in the frequency, intensity, and duration of heatwaves in the coming decades this threat to life …

Development of a Novel Fine Coal Cleaning and Dewatering Technology
… practice also has the potential to create an environmental hazard associated with blackwater pollution. To address these issues, researchers at Virginia Tech have worked over the past decade to develop a novel separation process that simultaneously removes both mineral matter and surface …

Zinc alloy powders for alkaline batteries
… Since mercury has been deemed as a health and environmental hazard, bismuth and indium are now used as alloying elements to suppress hydrogen evolution. Although alloying elements have been successfully incorporated in zinc powders, the problem with hydrogen evolution in alkaline batteries …

Assessment of soil erosion hazard around the abandoned mine in formerly Mutale Municipality, Limpopo Province, South Africa
Environmental degradation is a quite familiar factor of the mining industry that has been associated with South African mining industry from the beginning. The decommissioning of abandoned mines before the environment legislation, The National Environmental Management Act 107 of 1998 and the …

Computer modeling and experimental work on the astrobiological implications of the martian subsurface ionising radiation environment
… In this potential habitable zone, a major environmental hazard is the ionising radiation field generated by the flux of exogenous energetic particles: solar energetic protons and galactic cosmic rays. The research reported here constitutes the first multidisciplinary approach to assessing …

Social and scientific issues in the acceptibility of radiation risks
Ionising radiation hazards are perhaps the most documented and regulated occupational and environmental hazard. In the radiological protection field a single expert advisory organisation has had an unusually large influence on the international standard setting process. This is the International …

Rice Fortification by Parboiling in Limited-Water Soaking to Alleviate Mineral and Vitamin Deficiency
… processes employ excess water that presents an environmental hazard if discarded without treatment. Thus, the objective of this study was to evaluate a limited-water soaking method for the fortification of rice with calcium, iron, folic acid, β-carotene, and vitamin A. Excess- and limited-water …

Quantitative assessment of human gait patterns using biomechanical and dynamical tools
… or mobility, and extrinsic factors such as environmental hazard. Among these risk factors, we focused on impaired (dynamic) balance during human walking. Since impaired balance and gait are associated with fall risk, it is necessary to detect abnormal movement patterns due to gait impairment …

Catalytic, low temperature oxidation of methane into methanol over copper-exchanged zeolites
… become significant enough to be considered an environmental hazard and a wasted resource. The conversion of methane, the primary component of natural gas, into methanol, an easily stored liquid, is of practical interest. However, shale wells are generally inaccessible to reforming facilities, …

The eruptions of Örӕfajökull 1362 (Iceland) and Lanzarote 1730-36 (Canary Islands) : sulphur emissions and volcanology
… relates these findings to their atmospheric and environmental impacts. The Örӕfajökull eruption was an explosive Plinian event with high eruption columns (~30 Ian) that produced an extensive tephra-fall and a small pyroclastic flow deposit (~2 km3 total volume). In contrast, the Lanzarote …

Towards an understanding of synthetic glucocorticoid hazards in aquatic systems.
… surveillance methods. I conducted probabilistic environmental hazard assessments by employing environmental exposure distributions to estimate the probability of exceeding various hazard values. I observed synthetic glucocorticoids to be ubiquitous in freshwater systems, identified discrepancies …
