Design Of A Portable Swine Processing Machine For The Breschini & Sons Farm, Lee Breschini

BioResource and Agricultural Engineering

This senior project discusses the design factors associated with the construction of a portable swine processing machine. The portable swine processing machine is composed of the following stations linked to the entire meat processing system: internal organ removal station, rinsing/cleaning station, skin threshing station, and the refrigeration station. This project goes into depth of the function of each station and how it contributes to the ending result, the consumption of the wild hog. The processing machine meets all sanitation requirements and can be operated safely and efficiently, satisfying the needs of the Breschini & Sons farm.

Terrain Impacts From Vehicle Operations Across Multiple Passes, James Robert Kane

Masters Theses

This study, conducted on August 12th and 13th, 2008 at Fort Riley, Kansas on a clay loam soil, evaluated the terrain impacts of four commonly used tracked and wheeled military vehicles: the M1A1 Abrams Main Battle Tank, M998 High Mobility Multipurpose Wheeled Vehicle, M985 Heavy Expanded Mobility Tactical Truck, and M113 Armored Personnel Carrier. Disturbed width and impact severity were assessed along 14 spirals subjected to a maximum of eight consecutive passes for a total of 696 impact points. Data indicate that multiple passes produce increased vegetative impacts, with multipass coefficients ranging from 0.98 to 4.44 (compared to the commonly …

A Continuous Mathematical Model Of The One-Dimensional Sedimentation Process Of Flocculated Sediment Particles, Sebastian Fernando Torrealba

University of Kentucky Doctoral Dissertations

A new continuous one-dimensional sedimentation model incorporating a new continuous flocculation model that considers aggregation and fragmentation processes was derived and tested. Additionally, a new procedure to model sediment particle size distribution (PSD) was derived. Basic to this development were three different parametric models: Jaky, Fredlund and the Gamma probability distribution (GPD) were chosen to fit three different glass micro-spheres PSDs having average particle sizes of 7, 25 and 35 microns. The GPD provided the best fit with the least parameters. The bimodal GPD was used to fit ten sediment samples with excellent results (< 5% average error). A continuous flocculation model was derived using the method of moments for solving the continuous Smoluchowski coagulation equation with fragmentation. The initial sediment PSD was modeled using a bimodal GPD. This new flocculation model resulted in a new general moments’ equation that considers aggregation and fragmentation processes, which is represented by a system of ordinary differential equations. The model was calibrated using a genetic algorithm with initial and flocculated PSDs of four sediment samples and four anionic polyacrylamides flocculants. The results show excellent correlation between predicted and observed values (R² > 0.9878). A new continuous …

Water And Nutrient Balances Of Vegetative Treatment Systems For Feedlots In South Dakota, Daniel T. Ostrem

Electronic Theses and Dissertations

Vegetative treatment systems (VTS) are a possible alternative to storage basins for managing feedlot runoff but have not been researched in South Dakota. This study was conducted to evaluate the performance of VTS within South Dakota. The performance was evaluated by determining water and mass balances on each vegetative treatment area (VTA). The balances were determined by measuring all inflow, outflow, evapotranspiration, precipitation, and both soil and water nutrient concentrations within the VTA. Twelve site years have been completed in researching VTS from four feed lots in South Dakota. Seven of the twelve site-years VTS were able to prevent water …

Hydraulic Geometry Relationships And Regional Curves For The Inner And Outer Bluegrass Regions Of Kentucky, Ruth Roseann Brockman

University of Kentucky Master's Theses

Hydraulic geometry relationships and regional curves are used in natural channel design to assist engineers, biologists, and fluvial geomorphologists in the efforts undertaken to ameliorate previous activities that have diminished, impaired or destroyed the structure and function of stream systems. Bankfull channel characteristics were assessed for 14 United States Geological Survey (USGS) gaged sites in the Inner Bluegrass and 15 USGS gaged sites in the Outer Bluegrass Regions of Kentucky. Hydraulic geometry relationships and regional curves were developed for the aforementioned regions.

Analysis of the regression relationships showed that bankfull discharge is a good explanatory variable for bankfull parameters such …
