How Moisture Content Levels And Packing Density In Soil Affect Crude Oil Spreads, Shaylin N. Williams

Venture: The University of Mississippi Undergraduate Research Journal

Crude oil spills are one of the most destructive disasters that can occur, and they are extremely difficult to recover from. Many studies focus on what can be done to clean these crude oil spills, but more research should be focused on means of prevention. Currently, very little is known about how the moisture content levels and the packing efficiency of soil can affect an oil spill. These two factors alone can offer a variety of information to environmental agencies, manufacturers, and refineries. Through utilization of a chemical engineering lab, a recording mechanism, and ImagePro software, data was collected and …

Agenator: An Open Source Computer-Controlled Dry Aging System For Beef, Soon Kiat Lau, Felipe Azevedo Ribeiro, Jeyamkondan Subbiah, Chris R. Calkins

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Dry aging of beef is a process where beef is exposed to a controlled environment with the ultimate goal of drying the beef to improve its quality and value. Comprehensive investigations into the effects of various environmental conditions on dry aging are crucial for understanding and optimizing the process, but the lack of affordable equipment focused on data collection makes it difficult to do so. The Agenator was thus developed as an open source system with a suite of features for investigating dry aging such as: measuring and recording relative humidity, temperature, mass, air velocity, and fan rotational speed; precise …

Purdue Air Sense: A Methodology For Improving The Accuracy Of Ambient Aerosol Mass Concentration And Size Distribution Measurement With Low-Cost Optical Sensing Techniques, Rishabh Ramsisaria, Satya Sundar Patra, Brandon Emil Boor

The Summer Undergraduate Research Fellowship (SURF) Symposium

There is a global lack of a means for monitoring air pollutant levels at a local level due to expensive and bulky instrument requirements. It is important to monitor toxic gas levels, as well as particulate matter levels, in the atmosphere to study their effects on human health and to further develop city- and community-level air pollution solutions. In this study, with the means of a Raspberry Pi, low-cost Alphasense Optical Particle Counter and gas sensors, and methodical calibration techniques, we built a portable 3-D printed module powered by clean electricity generated by an on-board Voltaic solar cell that measures …

Impact Of Vegetative Treatment Systems On Multiple Measures Of Antibiotic Resistance In Agricultural Wastewater, Lisa M. Durso, Daniel N. Miller, Christopher G. Henry

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Wastewater is an important vector of antibiotic resistant bacteria and antibiotic resistance genes (ARB/G). While there is broad agreement that ARB/G from agricultural (ag) wastewaters can be transported through the environment and may contribute to untreatable infectious disease in humans and animals, there remain large knowledge gaps surrounding applied details on the types and amounts of ARB/G associated with different agricultural wastewater treatment options and different ag production systems. This study evaluates a vegetative treatment system (VTS) built to treat the wastewater from a beef cattle feedlot. Samples were collected for three years, and plated on multiple media types to …

Environmental Fullerene Chemistry: Elucidating Critical Reaction Pathways And Resulting Products In The Aqueous Phase, Jiewei Wu

McKelvey School of Engineering Graduate Student Theses & Dissertations

As the production of fullerenes and fullerene-based materials approaches industrial scale, there are increasing interests/concerns regarding their (potential) environmental impact(s) upon release. To date, a number of critical, aqueous-based fullerene transformation pathways under environmentally relevant conditions remain poorly understood. Comprehensive, fundamental, and quantitative understanding of the potential (major) reaction pathways and resulting products of fullerene materials, particularly in aquatic systems, is now crucial for their accurate fate, transport, life cycle, risk assessment(s), and thus ultimate material sustainability.

Herein, this dissertation is focused on identifying and elucidating aqueous transformation pathways of fullerene materials, focused on C60 as a model fullerene, under …

Sustainable Architecture Design: Environmental And Economic Benefits, Michael Babcock

Senior Honors Theses

This thesis examines the movement of environmentalism, and its impact on architecture and construction. During an interview with a professional architect, a basis for research of sustainable design was devised, when he explained that “good” architecture attempts to holistically integrate the external and built environment. Presently, the main measurement for sustainability is energy efficiency. Therefore, architects constantly implement new technology in an attempt to unify both the external and built environment in an energy efficient manner. Furthermore, this thesis provides an environmental and financial cost analysis of implementing sustainable design and build. Research shows that the life cycle and up-front …

Thawing Out: The Role Of The Arctic Council Service In A Melting Arctic, Taylor J. Enos

Pell Scholars and Senior Theses

With the changing natural and political climate of the Arctic, conflicts over resource extraction and navigation will become inevitable. Empowering an intergovernmental institution like the Arctic Council Service may be the only solution. This paper analyzes the importance and history of the Arctic as a political environment, which is prone to abuse in the very near future at the hands of Russia and the United States.

A Sustainability-Based Project Selection Algorithm: Socio-Technical-Economic Project Selection (Steps) Algorithm, Bharathi Bhattu

Dissertations, Master's Theses and Master's Reports

Multi-dimensional aspects play a vital role in the task of project-decision making. Environmental effects are to be considered in addition to other technical and non-technical aspects in order to avoid undue environmental damage. This current work introduces a new decision-making algorithm (Socio-Technical-Economic Project Selection or STEPS) that is demonstrated with the use of RCA (recycled concrete aggregate) as riprap for slope stabilization and erosion control which leaches chemical arsenic when in contact with water. Arsenic has long been recognized for its lethal properties. The main intention of introducing this new algorithm is to use sustainability concepts of social, technical, and …

Coal Fired Power Station Ash Products And Eu Regulation, Lindon K.A. Sear

Coal Combustion and Gasification Products Journal Archive

The UK has a long history of the use of coal fired power station ash products in a range of applications in construction. These range from use in concrete as a cementitious material through to its use as a fill material in embankments. While there have been no environmental problems associated with these uses, environmental regulations emanating from the European Union (EU) are increasingly impacting on the use of these materials. Unfortunately it is not a single set of regulations that are being applied, but three separate and apparently disconnected initiatives; these are Registration, Evaluation and Authorisation of Chemicals (REACH), …
