Mercury emissions from crematoria
… overlooked. This study investigated mercury emissions from crematoria by means of soil and air sampling programmes. The extent of exposure to the mercury by the crematoria workers was then determined by a hair-sampling programme. The soil monitoring and analysis programme involved five …

Heritability of Spontaneous Otoacoustic Emissions
Spontaneous otoacoustic emissions (SOEs) are narrow-band signals emitted from the cochlea and measured in the ear canal with a sensitive microphone. Because these emissions are correlated with sex and because sex is genetically determined, Bilger et al. (1990) hypothesized that SOEs were inherited. …

Industrial growth and emissions in emerging economies : decomposition of manufacturing CO2-emissions from fuel combustion
… Trend als auch das Zutreffen der Hypothese einer emissionsintensiven Industrieverlagerung.

Exhausted with Emissions: Exploring the Link Between Anthropogenic Emissions and Urban Pollution on Public Health
… we investigate how reducing transportation emissions and other anthropogenic emissions of NOx affects local and national public health in two heavily populated and polluted areas: Los Angeles, CA and New York City, NY. We estimate the Tipping Point (TP) as well as the Break-Even Point (BEP) …

Quantifying Emissions and Costs of Geologic Hydrogen: An Integrated Lifecycle Emissions and Techno-economic Approach
… solutions, this thesis explores the lifecycle emissions and economic feasibility of geologic hydrogen production. This research extends Brandt's 2023 study of 'prospective' lifecycle assessment (LCA), enhancing the underlying open-source LCA model used in this work and adding a preliminary …

Optical Emissions Generated During Ionospheric Heating
… leading to the production of induced optical emissions. Detection of these emissions yields information regarding wave-plasma interactions, which are of fundamental importance in many physical processes, and provides an effective means of remotely sensing ionospheric constituents and …

Heavy-duty emissions inventory and prediction
Heavy duty vehicle emissions represent a significant portion of the mobile source emissions inventory. Accurate estimation of their contribution is essential as on-highway and non-road heavy duty diesel emissions account for at least one third of the oxides of nitrogen (NOx) in the inventory. West …

Vehicular Ammonia Emissions in Baltimore, Maryland
… H2 in the three-way catalytic converter. Ammonia emissions were measured using a mass balance on the Fort McHenry Tunnel, Baltimore, Maryland. Atmospheric concentrations of gas-phase and particulate-phase ammonium were measured during 2003-2004 using denuders and filter packs. The average vehicle …

Investigation of Methane Emissions and Sources
… to monitor, characterize, and quantify CH4 emissions and sources through three observational platforms including Remote Methane Leak Detector mounted on an Unmanned Aerial Vehicle (RMLD-UAV), the UH mobile laboratory, and the Moody tower stationary site. The RMLD-UAV system provided an …

Emissions of Bioaerosols from Composting Facilities
… one of the major public health concerns is the emissions of bioaerosols from the composting sites. Bioaerosol dispersion across composting facilities, due to operational activities, may have significant effects on human health due to the fact that they can penetrate into the human respiratory …

Quantifying avoided emissions from renewable generation
Quantifying the reduced emissions due to renewable power integration and providing increasingly accurate emissions analysis has become more important for policy makers in the age of renewable portfolio standards (RPS) and emerging carbon markets. This study focuses on the method of quantifying the …

Nitrous oxide and methane emissions from agriculture and approaches to mitigate greenhouse gas emissions from livestock production
… studies and reviews of greenhouse gas (GHG) emissions and their abatement from agriculture, in particular from livestock production. The aims of the work were to: quantify GHG emissions from litter-based farmyard manures; evaluate means by which GHG emissions from agricultural production may …

Impact of European Emissions Trading System (EU-ETS) on carbon emissions and investment decisions in the power sector
This masters thesis assesses the impact of a emissions trading on short-term carbon abatement and investment decisions in the power sector. Environmental benefits from carbon abatement due to emissions trading are quantified using top-down trend analysis and a bottom-up power sector model …

Measuring Methane Emissions in the Urban Environment
Mitigating methane (CH4 ) emissions is a necessary intervention to address the immediate impacts of anthropogenic climate change. Bottom-up inventories and models are used to predict the quantity of CH4 emissions, but these estimates are poorly constrained, especially on a source-by-source basis. …

Case Studies of IMF Driven Auroral Emissions
… interplanetary magnetic field and the auroral emissions of southern hemisphere dayside polar cusp. The specific emissions used are the 6300 A and 8446 A, as these are due to direct electron impact. Data was obtained via a meridian scanning photometer, CCD spectrograph, and NASA's WIND & ACE …
