Heavy Oil Production, Review Paper, Mohamed Abd El-Moniem

Emirates Journal for Engineering Research

Petroleum represents an important source of energy. The different resources for energy are classified into renewable and non-renewable. Petroleum is the main source of the non-renewable energy where it is found in conventional and non-conventional reservoirs. Conventional oil production is started since the last century with a high oil and gas production using primary and secondary recovery. Now, the global demand is high compared to the supply from the existing produced fields. The production is declining from the conventional resources, so the production from the unconventional reservoirs is essential to cover the market demand. The unconventional resources are classified as …

Dissemination And Visualization Of Hydro-Climate Data In Sub-Saharan Africa For Analysis Of Climatic Parameters, Divyadharshini Karthikeyan, Aparna S. Varde, Clement Alo

School of Computing Faculty Scholarship and Creative Works

Precipitation can have adverse effects on the climate ecosystem. Too much can impose concerns such as flooding and landslides, resulting in damaged property, agricultural losses, and loss of life. Too little, and drought becomes an issue, inducing wildfires, poor air quality, agricultural losses, and health degradation. While much work has been performed on historical and projected analysis of heavy precipitation, few interactive visualizations exist for end-users to better understand local impacts. The goal of this project is to create a visualization tool that easily demonstrates how precipitation extremes have changed and might change in the future for Sub-Saharan Africa. This …

Assessment Of Switchgrass-Based Bioenergy Supply Using Gis-Based Fuzzy Logic And Network Optimization In Missouri (U.S.A.), Gia Nguyen, Erik Lyttek, Pankaj Lal, Taylor Wieczerak, Pralhad Burli

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Bioenergy has been globally recognized as one of the sustainable alternatives to fossil fuels. An assured supply of biomass feedstocks is a crucial bottleneck for the bioenergy industry emanating from uncertainties in land-use changes and future prices. Analytical approaches deriving from geographical information systems (GIS)-based analysis, mathematical modeling, optimization analyses, and empirical techniques have been widely used to evaluate the potential for bioenergy feedstock. In this study, we propose a three-phase methodology integrating fuzzy logic, network optimization, and ecosystem services assessment to estimate potential bioenergy supply. The fuzzy logic analysis uses multiple spatial criteria to identify suitable biomass cultivating regions. …

Applying A Systems Approach To The Legacy Of Lead In Soil, Sara Perl Egendorf

Dissertations, Theses, and Capstone Projects

Lead (Pb) in soil is a global environmental issue. The particularly high lead concentrations found in surface soils have been emplaced by humans and bring with them life-altering and life-shortening effects for our species and countless others. While much of the general population is unaware of lead lurking in our soils, scientists from a range of backgrounds have generated a body of research documenting this ubiquitous phenomenon, arising from sources such as lead in gasoline, paint, industry, and incineration. Scientists have also explored ways to remediate soil and continue calling for efforts to limit toxicant exposure. Why, then, does this …
