Cost Benefit Analysis Of The Keystone Xl Pipeline, Daniel Carr
Cost Benefit Analysis Of The Keystone Xl Pipeline, Daniel Carr
Honors Theses
The Keystone XL pipeline is one of the most controversial topics in North America over the last five years. The debate is based on the trade‐off between Canadian oil sands as a usable energy resource and the environmental effects associated with the extraction and refining of the oil. The green house gasses emitted from the extraction and refining of oil sands produces several environmental concerns that make the proposed pipeline controversial. On the other hand, Canadian oil companies see a significant benefit from the ability of Canadian oil reaching international markets. TransCanada, a 79.99 percent owner of the pipeline, conducted …
Proving Widespread Deforestation Of The Ancient Mediterranean As Myth: A Detailed Examination Of How Anthropogenic Activities During Antiquity Affected The Mediterranean Landscape, Carolyn Hooper
Honors Theses
This thesis examines the debate surrounding the possible deforestation of the ancient Mediterranean landscape through anthropogenic activities. Until the ancient Mediterranean landscape is understood more clearly, it is impossible to impose current beneficial land-use laws in order to conserve and preserve the future landscape of the region. Currently there are three predominant views surrounding the debate: (1) deforestation did occur and drastically altered the landscape from a forested region to a more desert-like region, (2) human activities did not cause deforestation, rather the Mediterranean has always been home to a distinct and resilient landscape that is able to regenerate following …
The Effect Of Azo Textile Dyes On Gross Primary Production And Community Respiration In An Artificial Environment, Theresa L. Petzoldt
The Effect Of Azo Textile Dyes On Gross Primary Production And Community Respiration In An Artificial Environment, Theresa L. Petzoldt
Honors Theses
Azo dyes are the largest category of textile dyes in production today, with over 100,000 tons of dye produced yearly in the United States. Ten to fifty percent of this dye is not fixed to the fabric during the textile production process, and is therefore discarded as effluent. Because dye waste is difficult to process in wastewater treatment facilities, it is important to understand how this waste affects aquatic systems using a whole ecosystem approach. This study used an artificial stream to model the effects of four azo dyes on benthic biofilm production and respiration. Dyes were found to have …
