Evaluation Of Capital Investment And Cash Flows For Alternative Switchgrass Feedstock Supply Chain Configurations, Jie Chen
Masters Theses
Biofuels have been widely recognized as a potential renewable energy source, and the United States’ government has been interested in producing ethanol from lignocellulosic biomass such as switchgrass. To evaluate whether lignocellulosic biomass based biofuels production is economically feasible, this paper estimated the capital investment outlays, operation costs, and net present value for investment in alternative switchgrass feedstock supply chain configurations in East Tennessee a 25 million gallon per year ethanol biorefinery. Two scenarios are analyzed in the study. The conventional hay harvest scenario includes the production, harvest, storage and transportation of biomass feedstocks from the fields to the biorefinery. …
Potential For Alternative Agricultural Enterprises To Replace Tobacco: Burley Producers Perceptions, Maria Paula Mendieta Umana
Potential For Alternative Agricultural Enterprises To Replace Tobacco: Burley Producers Perceptions, Maria Paula Mendieta Umana
Masters Theses
Demand for domestic tobacco has decreased over the past two decades. In 2004, the tobacco buyout program terminated marketing quotas and price support established under the federal tobacco program in 1938. Additionally, in 2003, the World Health Organization Framework Convention on Tobacco Control (WTO FCTC) acknowledged the importance of supply control in conjunction with demand control strategies to eliminate or reduce the consumption of tobacco products. According to the Census of Agriculture, the number of tobacco farms in the US fell by 40 percent between 2002 and 2007. Tobacco farmers are looking for alternative on-farm and off-farm sources of income. …
Intellectual Property And Policy Issues In Biotechnology, Amy Iver Yancey
Intellectual Property And Policy Issues In Biotechnology, Amy Iver Yancey
Masters Theses
Intellectual property, particularly patents, plays a major role in innovation and discovery in biotechnology. Likewise, since the passage of the Bayh-Dole Act in 1981, patents have become an increasingly important factor in U.S. university-driven basic research, especially in the life sciences where patented technologies have transformed agriculture. Specifically, this paper looks at the potential impacts of these trends on university driven research, the university researcher, the pharmaceutical industry, and the farm sector with an emphasis on recent and pending court cases and legislation. This paper examines policy and adoptions issues in biotechnology and biomedicine in depth and touches on important …
An Investigation Of Stratigraphic Evidence For An Abrupt Climatic Event 8200 Yr Bp In Valle De Las Morrenas, Costa Rica, Brian Thomas Watson
An Investigation Of Stratigraphic Evidence For An Abrupt Climatic Event 8200 Yr Bp In Valle De Las Morrenas, Costa Rica, Brian Thomas Watson
Masters Theses
Lago de las Morrenas 4 (9.498056° [degrees] N, 83.486111° [degrees] W, 3466 m elev.) is the lowest lake in a chain of glacial lakes located in the Valle de las Morrenas, a valley facing almost due north from Cerro Chirripó, the highest peak in the Cordillera de Talamanca in Costa Rica. Coarse resolution analyses of pollen, microscopic charcoal, and loss-on-ignition of a ca. 10,000 year sediment record from Lago de las Morrenas 4 was carried out to complement and extend previous research on the environmental history of the Chirripó highlands and to provide context for high-resolution sampling and analysis of …
