  • During a Foreign Animal Disease (FAD) outbreak, it is critical that people, equipment, and vehicles do not inadvertently move the disease-causing agent between premises (i.e., locations where animals are housed or otherwise handled).
  • To prevent this potential transmission, a cleaning and disinfection (C&D) station must be established at the clean/dirty line on infected premises, and everything going on or off the premises pass through it.
  • Without this critical precaution, more viruses may remain in the environment and cause potential infection of other premises and herds; thus, making FAD containment a challenge.

The Environmental Health and Safety Storm Water Program has used the RUSLE2 model for many years to quantify success by measuring the effectiveness of the ISU campus Storm Water Management Program. RUSLE2 provided estimates of the soil loss prevented by implementing Best Management Practices (BMPs) specified in the Iowa Statewide Urban Design and Specifications for construction sites. ISU reports these estimates to the Iowa Department of Natural Resources each year in the annual report required by the Municipal Separate Storm Sewer System (MS4) permit. With the development of the newer WEPP (water erosion prediction project) model, it is beneficial to ...

Smithfield Hog Production has processing facilities throughout the state of Iowa as well as contract finishing sites where producers grow out their swine. The hog manure from these sites is pumped into a slurry store for storage until it can be pumped onto the fields in the spring or fall. The slurry stores stand 19-feet-tall, have a diameter of 120-feet, and hold 1.2-million-gallons of manure. The slurry stores have no cover so they are open to all weather like rain and snow.

Most years, evaporation does not equal precipitation which results in a decreased manure holding capacity and an ...

An Environmental And Economic Analysis Of Flocculation Technology Applied To A Corn-Based Ethanol Plant, Maria C. T. B. Oliveira, Kurt A. Rosentrater 2020 Iowa State University

An Environmental And Economic Analysis Of Flocculation Technology Applied To A Corn-Based Ethanol Plant, Maria C. T. B. Oliveira, Kurt A. Rosentrater

Agricultural and Biosystems Engineering Publications

The stimulation of renewable fuel production is related to the environmental issues resulting from the extraction and utilization of fossil fuels. Although corn-based ethanol is one of the leading renewable fuels and promises to mitigate these environmental impacts, it generates large volumes of wastewater with high concentrations of organic material (CODcr > 30,000 mg/L) and low pH (3.5–4.5), which leads to serious environmental concerns. A common method of treatment of distillery wastewater is the Dry Distilled Grain Soluble (DDGS) process, which separates liquid and solid fractions; however, a disadvantage of this process is its high ...


Effects Of Farrowing Stall Layout And Number Of Heat Lamps On Sow And Piglet Production Performance, Suzanne M. Leonard, Hongwei Xin, Tami M. Brown-Brandl, Brett C. Ramirez, Somak Dutta, Gary A. Rohrer 2020 Iowa State University

Effects Of Farrowing Stall Layout And Number Of Heat Lamps On Sow And Piglet Production Performance, Suzanne M. Leonard, Hongwei Xin, Tami M. Brown-Brandl, Brett C. Ramirez, Somak Dutta, Gary A. Rohrer

Agricultural and Biosystems Engineering Publications

Most farrowing facilities in the United States use stalls and heat lamps to improve sow and piglet productivity. This study investigated these factors by comparing production outcomes for three different farrowing stall layouts (traditional, expanded creep area, expanded sow area) and use of one or two heat lamps. Data were collected on 427 sows and their litters over one year. Results showed no statistical differences due to experimental treatment for any of the production metrics recorded, excluding percent stillborn. Parity one sows had fewer piglets born alive (p < 0.001), lower percent mortality (p = 0.001) and over-lay (p = 0.003), and a greater number of piglets weaned (p < 0.001) with lower average daily weight gain (ADG) (p < 0.001) and more uniform litters (p = 0.001) as compared to higher parity sows. Farrowing turn, associated with group/seasonal changes, had a significant impact on most of the production metrics measured. Number of piglets born influenced the percent stillborn (p < 0.001). Adjusted litter size had a significant impact on percent mortality (p < 0.001), percent over-lay (p < 0.001), and number of piglets weaned (p < 0.001). As the number of piglets weaned per litter increased, both piglet ADG and litter uniformity decreased (p < 0.001). This information can be used to guide producers in farrowing facility design.

Chemical and Biological Engineering Publications

Technoeconomic analyses using established tools such as SuperPro Designer® require a level of detail that is typically unavailable at the early stage of process evaluation. To facilitate this, members of our group previously created a spreadsheet-based process modeling and technoeconomic platform explicitly aimed at joint fermentative‒catalytic biorefinery processes. In this work, we detail the reorganization and expansion of this model—ESTEA2 (Early State Technoeconomic Analysis, version 2), including detailed design and cost calculations for new unit operations. Furthermore, we describe ESTEA2 validation using ethanol and sorbic acid process. The results were compared with estimates from the literature, SuperPro Designer ...


A Greenhouse Gas Emissions Inventory For Nebraska: Livestock And Coal Loom Large, Eric Holley, Adam Liska 2020 University of Nebraska-Lincoln

A Greenhouse Gas Emissions Inventory For Nebraska: Livestock And Coal Loom Large, Eric Holley, Adam Liska

Adam Liska Papers

Mitigation of climate change requires the systematic identification and cataloging of emissions sources at city, state, and national levels. In this study, an inventory of annual greenhouse gas emissions from the state of Nebraska was created based on industry data, and emissions inventories were completed each year from 1990 to 2016. Nebraska’s net emissions were found to increase from 56.2 million metric tons of carbon dioxide equivalents (MMtCO2e) in 1990 to 87.4 MMtCO2e in 2016. Agriculture was found to be the sector with the most emissions (36 MMtCO2e) followed by electricity ...

In Exp. 1, 15 barrows (88.4 ± 6.4 kg) were allotted to either a corn starch-soybean meal (CST), potato starch-soybean meal (PST), or corn-soybean meal (CSBM) diet, over 2 collection periods. Following collection, samples were pooled within pig and subdivided into either OD or FD, resulting in 10 observations per diet by drying method combination. In Exp. 2, 11 barrows (63.3 ± 3.8 kg) were fed a CST ...


Cost Assessment Of Five Different Maize Grain Handling Techniques To Reduce Postharvest Losses From Insect Contamination, Bernard Darfour, Kurt A. Rosentrater 2020 Ghana Atomic Energy Commission

Cost Assessment Of Five Different Maize Grain Handling Techniques To Reduce Postharvest Losses From Insect Contamination, Bernard Darfour, Kurt A. Rosentrater

Agricultural and Biosystems Engineering Publications

Farmers in developing nations encounter high postharvest losses mainly attributable to the lack of modern techniques for threshing, cleaning, grading, and grain storage. Mechanized handling of grain in developing countries is rare, although the technology is effective against insects and pest infestations. The objective was to evaluate the cost-effectiveness of five grain handling techniques that have the ability to reduce postharvest losses from insect infestation. The five methods were metal silo plus all accessories (m. silo + acc.), metal silo only (m. silo), woven polypropylene plus phosphine (w. PP. + Phos.), woven polypropylene only (w. PP.), and Purdue Improved Crop Storage bags ...


Stability And Evolution Of Planar And Concave Slopes Under Unsaturated And Rainfall Conditions, Arash Hassanikhah, Eric C. Drumm 2020 University of Tennessee, Knoxville

Stability And Evolution Of Planar And Concave Slopes Under Unsaturated And Rainfall Conditions, Arash Hassanikhah, Eric C. Drumm

Biosystems Engineering and Soil Science Publications and Other Works

Natural slopes are often observed to have a concave, convex, or a combination concave/convex profile, yet constructed slopes are traditionally designed with planar cross-sectional geometry. In this paper, the stability of two planar slopes was compared with that of companion concave slopes, designed to have similar factors of safety (FOS) under gravity loading. The stability of these slopes was then investigated in response to a suction event followed by a precipitation event, and it was shown that both the planar and the concave slopes experienced similar changes in stability. Additional analyses were conducted with a simulated erosion mechanism to ...

Dynamics Of Corn Dry Matter Content And Grain Quality After Physiological Maturity, Md Rasel Parvej, Charles R. Hurburgh, H. Mark Hanna, Mark A. Licht

Agronomy Publications

Delayed corn (Zea mays L.) harvest after physiological maturity (PM) is a universal practice in the U.S. Corn Belt to reduce grain drying cost. However, corn yield is speculated to be lost due to kernel dry matter loss from seed respiration. We evaluated the impact of in‐field dry down on corn dry matter content and grain quality after PM at two locations in Iowa during 2016 and 2017. Each site‐year consisted of two planting dates and three hybrids where ears were collected six to eight times from PM to harvest. Regardless of site‐year and hybrid, grain ...

Field Assessment Of Interreplicate Variability From Eight Electromagnetic Soil Moisture Sensors, Tsz Him Lo, Daran Rudnick, Jasreman Singh, Hope Njuki Nakabuye, Abia Katimbo, Derek M. Heeren, Yufeng Ge

Biological Systems Engineering: Papers and Publications

Interreplicate variability—the spread in output values among units of the same sensor subjected to essentially the same condition—can be a major source of uncertainty in sensor data. To investigate the interreplicate variability among eight electromagnetic soil moisture sensors through a field study, eight units of TDR315, CS616, CS655, HydraProbe2, EC5, 5TE, and Teros12 were installed at a depth of 0.30 m within 3 m of each other, whereas three units of AquaSpy Vector Probe were installed within 3 m of each other. The magnitude of interreplicate variability in volumetric water content (θv) was generally similar between ...

Prediction Of Neighbor-Dependent Microbial Interactions From Limited Population Data, Joon-Yong Lee, Shin Haruta, Souichiro Kato, Hans C. Bernstein, Stephen R. Lindemann, Dong-Yup Lee, Jim K. Fredrickson, Hyun-Seob Song

Biological Systems Engineering: Papers and Publications

Modulation of interspecies interactions by the presence of neighbor species is a key ecological factor that governs dynamics and function of microbial communities, yet the development of theoretical frameworks explicit for understanding context-dependent interactions are still nascent. In a recent study, we proposed a novel rule-based inference method termed the Minimal Interspecies Interaction Adjustment (MIIA) that predicts the reorganization of interaction networks in response to the addition of new species such that the modulation in interaction coefficients caused by additional members is minimal. While the theoretical basis of MIIA was established through the previous work by assuming the full availability ...


Soil Bulk Density Effects On Runoff Estimation, Colton Pugh 2020 University of Kentucky

Soil Bulk Density Effects On Runoff Estimation, Colton Pugh

Theses and Dissertations--Biosystems and Agricultural Engineering

Urbanization has long been a major factor in the hydrology of surrounding areas. Engineers are commonly tasked with mitigating the extra runoff that urbanization brings with it. The NRCS Curve Number (CN) method is a commonly-used approach to predicting the amount of runoff that will be experienced from a given area. However, this method is known to be highly simplified in model of the processes involved. This study focused on determining the relationships between soil bulk density, simulated rainfall events, hydrologic soil group (HSG) and runoff estimation (specifically via the NRCS CN method). It was determined that soil bulk density ...

Uncoated resonant sensors are presented here for wireless monitoring of solvated ions, with progress made toward monitoring nitrates in agricultural runoff. The sensor, an open-circuit Archimedean coil, is wirelessly interrogated by a portable vector network analyzer (VNA) that monitors the scattering parameter response to varying ionic concentrations. The sensor response is defined in terms of the resonant frequency and the peak-to-peak amplitude of the transmission scattering parameter profile (|S21|). Potassium chloride (KCl) solutions with concentrations in the range of 100 nM – 4.58 M were tested on nine resonators having different length and pitch sizes to study the effect ...
