Transmission of Toxoplasma gondii on swine farms was investigated using a deterministic dynamic computer simulation model. A primary focus was to evaluate a feline T. gondii vaccine. Animal populations (swine and cats) were compartmentalized based on the stage of T. gondii infection. Simulations were run under conditions of closed and equilibrium population(More)
(1) Publish a theoretical manuscript (or group of manuscripts) that articulates our interdisciplinary approach to global ecosystem service valuation (2) Create a database that brings relevant social, economic, and ecological data together in a fully relational format (3) Develop an integrated, dynamic model of ecological and economic systems to more(More)
Research on the valuation of environmental externalities shows that decision makers tend to discount not only over time but across space. Just as time discounting has implications for intergenerational equity,geographical or spatial discounting has implications for intragenerational equity. Similarly, just as positive time discount rates are warranted by(More)
New once daily mesalamine formulations may improve adherence to medication usage. Response to Asacol and other forms of 5-aminosalicyclic acid (5-ASA) is better correlated with tissue concentrations and best predicted by concentrations of the drug within the lumen of the colon. Our group used computer simulation to predict colonic 5-ASA levels after Asacol(More)
An energy input-output model was used to investigate energy and employment in the construction industry. The model covered nearly 400 industrial sectors and was used to determine the impact of construction activities on total national energy consumption in 1967 and to study the patterns of total energy use and employment within various construction(More)
The research of the Energy Research Group (ERG) at the University of Illinois at Urbana-Champaign through the 1970s and early 1980s has recurring bouts of popularity. That research traced the flow of various energy types from nature to the final product or service, using modified economic input-output analysis. That information allowed for a comparison of(More)
BACKGROUND 5-Aminosalicylate (5-ASA) formulations are approved for the treatment of ulcerative colitis (UC). Determination of the colonic pharmacokinetics of 5-ASA is challenging. A dynamic model of 5-ASA colonic amounts after oral delayed-release 5-ASA (Asacol), oral extended delayed-release 5-ASA (Lialda), 5-ASA enema (Rowasa), foam and suppositories(More)
