Design Considerations For The Construction And Operation Of Grain Elevator Facilities. Part Ii: Process Engineering Considerations, Kurt A. Rosentrater, Gregory D. Williams
Design Considerations For The Construction And Operation Of Grain Elevator Facilities. Part Ii: Process Engineering Considerations, Kurt A. Rosentrater, Gregory D. Williams
Kurt A. Rosentrater
Grain elevators play a key role in U.S. agriculture, and fulfill three main functions: post-harvest handling and storing of cereal grains and oilseeds, conditioning and preserving of grain, and facilitating the delivery of grain to domestic feeding and processing, as well as overseas, end-use destinations. These facilities have evolved from mere storage sites to large, high-throughput, highly automated, processing plants. This trend has been driven by the consolidation of local country elevators, which has been due, in part, to both local economic conditions as well as changing railroad regulations. Another reason has been an increased demand for grain storage space, …

Can-Based Distributed Control For Autonomous Vehicles, Matthew J. Darr, Timothy S. Stombaugh, Scott A. Shearer, John P. Fulton
Matthew J. Darr
Through the work of researchers and the development of commercially available products, automated guidance has become a viable option for agricultural producers. One limiting factor of many commercially available technologies is that they only automate one function of an agricultural vehicle and that their control systems are proprietary to a single machine model.The objective of this project was to evaluate a controller area network (CAN bus) as the basis of an automated agricultural vehicle. The prototype system utilized several microcontroller-driven nodes to act as control points along a system wide CAN bus. Messages were transferred to the steering, transmission, and …

Jacek A. Koziel
A laboratory study was conducted to evaluate how rate and timing of urease inhibitor application affects ammonia emissions from simulated beef cattle feedyard surfaces. The urease inhibitor N-(n-butyl)thiophosphoric triamide (NBPT) was applied at rates of 0, 1 and 2 kg/ha, at 8, 16, and 32 day frequencies, and with or without simulated rainfall. Synthetic urine was added every 2 days to the manure surface. Gaseous NH3 was trapped in a sulfuric acid solution using a vacuum system and analyzed for nitrogen using automated procedures. NBPT applied every 8 days was most effective, with the 1 and 2 kg/ha NBPT treatments …

Multidimensional Gas Chromatography-Olfactometry For Identification And Prioritization Of Malodors From Confined Animal Feeding Operations, Donald W. Wright, David K. Eaton, Lawrence T. Nielsen, Fred W. Kuhrt, Jacek A. Koziel, Jarett P. Spinhirne, David B. Parker
Jacek A. Koziel
Odor profiling efforts were directed at applying to high-density livestock operations, some of the lessons learned in resolving past, highly diverse, odor-focused investigations in the consumer product industry. Multidimensional-GC-Olfactometry was utilized in an attempt to define and prioritize the basic building blocks of odor character associated with representative cattle feedyard and swine feeding operations. Although scores of potential odorant volatiles have been previously identified in high-density livestock operations, the odor profile results developed herein suggest that only a very few of these may constitute the preponderance of the odor complaints associated with these environments. This appeared to be especially true …

Analysis Of Factors Affecting Corn Masa Byproduct Generation, Kurt A. Rosentrater
Analysis Of Factors Affecting Corn Masa Byproduct Generation, Kurt A. Rosentrater
Kurt A. Rosentrater
The production of corn masa-based products in the U.S. has been increasing over the last several years, and consequently, so has the volume of waste materials generated from this processing sector. These byproducts, which consist of corn dry matter losses that occur during the nixtamalization process, are currently underutilized, but have much potential for value-added processing and utilization, and thus hold the simultaneous promises of economic benefit for corn processors as well as decreased potential impact on surrounding ecosystems. Because information concerning masa byproducts, and the rate at which they are generated, is currently very limited and not readily available, …

Matthew J. Darr
Granular applicators equipped with variable-rate technology have gained popularity in recent years due to increased interests in variable-rate application. The purpose of this investigation was to characterize distribution patterns at varying rates and quantify rate transitions from various granular applicators. Both uniform- and variable-rate tests were conducted to assess the accuracy of variable-rate application from four granular applicators (2 spinner spreaders and 2 pneumatic applicators). The patterns results indicated a consistent triangular pattern for spinner spreader B and consistent patterns for pneumatic applicators C and D. However, applicator D produced pattern variations at the center and right side. Simulated overlap …

Pastoral Risk Management In Southern Ethiopia: Observations From Pilot Projects Based On Participatory Community Assessments, D. Layne Coppock, Solomon Desta, Seyoum Tezera, Rancis K. Lelo
Environment and Society Faculty Publications
The Borana pastoral system has come under increasing pressure as human populations grow and per capita availability of resources declines. Livestock exhibit large, periodic die-offs that threaten wealth accumulation and food security. Several types of interventions may improve risk management here. For example, there may be opportunity for some pastoralists to diversify their livelihoods. Here we report on a community-based process involving pilot projects begun since 2000. We have embraced Participatory Rural Appraisal (PRA) and Action Research (AR) as tools for investigation and empowerment of local people. Full PRAs were conducted for semi-settled communities, located near towns, to identify priority …

Estrogen Content Of Dairy And Swine Wastes, D. Raj Raman, Elizabeth L. Williams, Alice C. Layton, Robert T. Burns, James P. Easter, Adam S. Daugherty, Michael D. Mullen, Gary S. Sayler
D. Raj Raman
Naturally occurring estrogens in animal wastes may cause negative environmental impacts, yet their abundance in animal waste treatment and storage structures is poorly documented. To better quantify estrogen concentra tions in animal wastes, multiple waste samples were collected from treatment and storage structures at dairy and swine facilities and analyzed for concentrations of 17β-estradiol (E2), estrone (E1), and 17α-estradiol by gas chromatography−mass spectroscopy and by enzyme linked immunosorbent assay (E2 only). Mass ratios of each estrogen to the macronutrients nitrogen, phosphorus, and potassium were also determined. Because manure application rates are typically macronutrient-based, estrogen to macronutrient ratios are proportional to …

Detection And Quantification Of Airborne Conidia Of Fusarium Circinatum, The Causal Agent Of Pine Pitch Canker, From Two California Sites Using A Real Time-Pcr Approach Combined With A Simple Spore Trapping Method, Wolfgang Schweigkofler, Kerry O'Donnell, Matteo Garbelotto
Collected Faculty and Staff Scholarship
Pinus radiata (Monterey pine), a tree native to coastal California and Mexico, is widely planted worldwide for timber production. A major threat to Monterey pine plantations is the fungal disease pine pitch canker, caused by Fusarium circinatum (Hypocreales). We present a novel trapping approach using filter paper in combination with a rapid molecular method to detect the presence of inoculum in the air. The assay is also useful for diagnosing the presence of the pathogen on plants. The test is based on the F. circinatum specific primer pair CIRC1A-CIRC4A, which amplifies a 360-bp DNA fragment in the intergenic spacer region …
