Evaluating Livestock System Environmental Performance With Whole-Farm Nutrient Balance, Richard K. Koelsch
Evaluating Livestock System Environmental Performance With Whole-Farm Nutrient Balance, Richard K. Koelsch
Department of Agricultural and Biological Systems Engineering: Faculty Publications
As a part of the USEPA’s concentrated animal feeding operation (CAFO) final rule, all CAFOs are required to develop and implement a nutrient management plan (NMP). The USEPA’s emphasis on better management of nutrients appropriately targets a critical environmental issue associated with animal production. The concentration of animals in livestock feeding operations, often separate from feed grain production, requires importing of substantial quantities of feed nutrients. Due to the inefficiencies of nutrient utilization in livestock production, quantities of nitrogen (N) and phosphorus (P) in manure greater than can be utilized in local crop production often result. With the focus of …

A Framework For Describing And Classifying Multicriteria Portfolio Selection Problems: An Object-Oriented Approach, Heinz Roland Weistroffer, Charles H. Smith
A Framework For Describing And Classifying Multicriteria Portfolio Selection Problems: An Object-Oriented Approach, Heinz Roland Weistroffer, Charles H. Smith
Journal of International Technology and Information Management
Many decisions require not a single solution alternative, but a set or portfolio of alternatives. For example, a business generally produces not a single product, but a portfolio of products, and a project is tackled not by a single individual, but by a team of individuals. Unfortunately, the portfolio selection problem has been largely neglected in the literature. Though many specific problem environments have been discussed using heuristic, ad hoc methods, no general methodology or theory has been developed. This paper proposes an object-oriented framework to provide a theoretical foundation for future research on the portfolio selection problem.

Haemophilic Factors Produced By Transgenic Livestock: Abundance That Can Enable Alternative Therapies Worldwide, Kevin E. Van Cott, Paul E. Monahan, Timothy C. Nichols, William H. Velander
Papers in Biotechnology
Haemophilia replacement factors, both plasma-derived and recombinant, are in relatively short supply and are high-cost products. This has stymied the study and development of alternative methods of administration of haemophilia therapy even in the most economically advanced countries, owing to the large amounts of material needed because bioabsorption and bioavailability of haemophilic factors can be less than 10% when using non-intravenous routes of delivery. There is therefore a need to increase access to therapy worldwide by decreasing the cost and increasing the abundance so that therapy can be achieved through simplified, alternative delivery methods. Transgenic livestock have been used to …
