Technoeconomic analysis of jet fuel production from hydrolysis, decarboxylation, and reforming of camelina oil
Autor: Wei Cheng Wang, William L. Roberts, Kelly D. Zering, Robert H. Natelson
Publikováno v: Biomass and Bioenergy. 75:23-34
The commercial production of jet fuel from camelina oil via hydrolysis, decarboxylation, and reforming was simulated. The refinery was modeled as being close to the farms for reduced camelina transport cost. A refinery with annual nameplate capacity

Dynamic Systems Approach for Integrating Models and Frameworks Applied to the Pig Sector
Autor: John J. Classen, Kelly D. Zering, Shannon C Banner
Publikováno v: 2016 ASABE International Meeting.
While there have been attempts to combine economic, environmental, and social impacts using modeling at smaller scales (farm level, regional), the majority of these modeling methods remain static, are site-specific, and do not exhibit the capacity fo

Phosphorus Recovery from Covered Digester Effluent with a Continuous-Flow Struvite Crystallizer
Autor: Keith E. Bowers, Kelly D. Zering, Philip W. Westerman
Publikováno v: Applied Engineering in Agriculture. 26:153-161
Tests for phosphorus reduction by increasing magnesium and pH to form struvite (magnesium ammonium phosphate hexahydrate (MgNH4PO4· 6(H2O)) were conducted using effluent from a covered earthen anaerobic digester for swine manure. A cone-shaped cryst

Applying Target Costing in the Development of Marketable and Environmentally Friendly Products from Swine Waste
Autor: Gilroy J. Zuckerman, Kelly D. Zering, Yuang-Sung Al Chen
Publikováno v: The Engineering Economist. 53:156-170
Management of swine waste generated in the United States is a challenging problem facing engineers, farmers, scientists, regulators, and policy-makers. Technologies for processing and storing swine waste have not been fully developed and refined in a

Analysis of Changing Methods of Vertical Coordination in the Pork Industry
Autor: Kevin E. Smith, Kelly D. Zering, Stephen W. Martinez
Publikováno v: Journal of Agricultural and Applied Economics. 30:301-311
This study examines the motivation behind contracts and vertical integration in the pork industry, and simulates the effects of potential improvements in coordination. Incentives related to lowering costs of measuring and sorting hogs, and protecting

Case study research methods for firm and market research
Autor: Kelly D. Zering, Randall E. Westgren
Publikováno v: Agribusiness. 14:415-423
Case studies are a useful analytical tool for researching firms and industries in transition, so as to gain insights that may not be found in historical time series. However, it is incumbent on researchers to show process rigor in using this tool for
