Applied Steady-State And Transient Modeling Of Mixing Zone Requirements In Streams, Alvin Castro

Retrospective Theses and Dissertations

Two existing stream dispersion computer models were applied to a hypothetical stream to analyze mixing zone requirements due to point and non-point discharges. Mixing zone curves were developed to define acceptable and unacceptable regions of stream response for stead-state and transient conditions. The impact on these regions due to varying quantitative and qualitative characteristics of the stream and waste discharges were investigated.

In addition, a sensitivity analysis was conducted on the response of a transient one-dimensional stream dispersion model. A logarithmic linear regression analysis, relating the number of time increments specified to a dimensionless hydrograph shape factor for known storm …

Heavy Metals In Floodplains Receiving Highway Bridge Runoff, Elizabeth T. Skene

Retrospective Theses and Dissertations

A study was supported by SUS/STAR to investigate the fate of heavy metals in bridge runoff which are received by surrounding floodplains. Three bridge sites in Central Florida were selected and various locations in each site were sampled. Soil, plant, and water samples were analyzed for Cd, Zn, Cu, Fe, Pb, Ni and Cr. Statistical analysis of results for heavy metal content of plants and soils at control versus bridge sampling areas were conducted. In agreement with other investigators, Pb was found to be a good indicator of highway pollution in soil, plants and water. Possible mechanisms for metal sorption …

All HMC Faculty Publications and Research

A feasibility design and cost estimate was completed for a 1 megawatt photovoltaic (PV) facility which would float on an island reservoir at Catalina Island off the coast the coast of Southern California. If built, this project would be one of the largest PV operating facilities to date and also the first floating PV system. The modular facility consists of 250 floating platforms each supporting 430 square feet of flat panel PV cells. This facility would provide 25% of Catalina's yearly peak energy demand and reduce the amount of diesel fuel used.

Correlation Of Road Rater And Benkelman Beam Deflections, Robert C. Deen, Gary W. Sharpe, Herbert F. Southgate

Kentucky Transportation Center Research Report

The Benkelman beam is commonly used to measure surace deflections of highway and airfield pavements. The Benkelman beam is based on a simple lever-arm principal and uses dial guages to measure surface deflections under an applied axleload. The Road Rater is an electro-hydraulic testing device that applies a sinusoidal force to the pavement at a fixed amplitude and frequency: surface wave velocities are measured and electronically integrated to obtain surface deflections. Road Rater and Benkelman beam deflections have been successfully simulated using elastic theory and the Chevron N-layer computer program. The analyses presented in this paper illustrate relationships between Road …

Simulation Of Naval Training Pipelines, Roger H. Werner

Retrospective Theses and Dissertations

Flow of enlisted Navy men through basic training, BEE school and "A" school was simulated using SLAM. Queuing for courses, pass, setback and failure of students, and the limitation of resources in the BEE schools were modeled for variable numbers of "A" courses and enlisted student ratings. A travel delay between schools was modeled as a direct step function of the distance involved. For each course modeled, data included course duration, interconvening time between classes, minimum and maximum class sizes, pass, failure and setback rates, and the time, measured from the beginning of the simulation, when the first class is …

Effect Of Herbicides On Performance Of Aerobic Dairy Lagoons, John D. Bottom, Joseph L. Taraba

Biosystems and Agricultural Engineering Faculty Publications

The herbicides glyphosate, bromacil, and dalapon were assessed for their affect on the oxygen uptake of microorganisms from an aerated dairy lagoon at 20 °C. The maximum recommended addition of herbicide active ingerdient to a lagoon is: glyphosate (isopropyl amino salt)—0.42 mg/L; bromacil—3.70 mg/L; and dalapon (85.8 percent Na salt and 14.2 percent Mg salt)—1.95 mg/L. In addition, microorganism isolates from the aerobic dairy lagoon were incubated under aerobic and anerobic conditions at room temperature to assess the effects of the herbicides. Under aerobic incubation, it was found that neither herbicide type nor herbicide concentration affected isolate growth. Under anaerobic …

Tillage Factors Affecting Corn Seed Spacing, Paul J. Jasa, Elbert C. Dickey

Department of Agricultural and Biological Systems Engineering: Faculty Publications

An on-farm survey was conducted in Nebraska to determine factors affecting corn seed spacing uniformity. Statistical analysis indicated that relative surface roughness, amount of residue present, amount of preplant tillage, and tillage system were important factors affecting uniformity. Subsequently, replicated tillage plots at eight locations were used to evaluate seed spacing uniformity with different planters and tillage systems. Seed spacing coefficient of variation and a planter index developed showed conservation tillage does not significantly reduce seed spacing uniformity.

Salt Buildup In Flush Recycle Systems, Joseph L. Taraba

Agricultural Engineering Extension Updates

A major operating problem that has occurred in recycle flush lagoon systems is the buildup of a crystalline solid in the recycle pipelines, pump, flush devices, and concrete gutters. The major crystalline solid has been identified as magnesium ammonium phosphate -- Mg(NH₄)PO₄. There have been a couple of reports of other types of phosphate salts of calcium and magnesium. All the cases of salt buildup in the recycle lines of swine flushing systems that have been investigated in Kentucky were found to be magnesium ammonium phosphate.

Effects Of Manure Handling Systems On Swine Health, Joseph L. Taraba

Agricultural Engineering Extension Updates

Modern swine production confinement systems have brought about significant improvements in the quantity and quality of meat products for human consumption. This has been achieved because of the ability to maintain good environmental conditions and to apply sound management techniques, therefore, allowing the animals to achieve maximum performance. These intensive production systems have animals in close proximity to each which results in the large quantities of manure that must be handled. Thus the manure system becomes an integral part of the total production system. If the manure is not handled in a sanitary manner, if the gases and odors from …

Safety Precautions With Liquid Manure Storage Systems: Warning--Manure Gases Can Be Dangerous, Larry R. Piercy, Joseph L. Taraba

Agricultural Engineering Extension Updates

A liquid manure system produces 4 gases which are potentially hazardous to workers and animals. The decomposing manure slowly releases these gases into the liquid and the surrounding atmosphere. During agitation of the manure large quantities of gas are released into the air. Tragic human deaths and animal losses have occurred during agitation or from humans entering the pit areas.

Performance And Evaluation Of A Variable-Speed Darrieus Wind Turbine, Kasey W. Abbott

Electronic Theses and Dissertations

Developing wind energy suitable for agriculture applications is a critical step towards providing a reliable, affordable energy supply for United States agriculture. United States agriculture, due to its energy intensive nature-, is dependent on petroleum fuels. Because agriculture is extremely sensitive, to supply interruptions, steps must be taken to reduce this dependence on oil, including developing wind energy systems. It appears that the potential is there since winds over the United States contain more than 30 times the total energy consumed in this nation (Soderholm, 1979).
Agricultural applications (e.g. irrigation pumping, product processing and building heating) are uniquely suited to …

Aggregate Shape And Skid Resistance, James H. Havens, Donald C. Newberry Jr.

Kentucky Transportation Center Research Report

Natural sands and sands manufactured by crushing larger parent materials are characterized and service tested. Singular attributes are usually confounded with other variables in service tests. Dry-bulking tests and photomicrography are used to established qualities. High-stability porous mixtures are achieved in laboratory tests. Crushing some materials to coarse chip sizes leaves many smooth facets on particles that then tend to become oriented horizontally in the pavement surface. Open-graded friction courses and sprinkle treatments are included. Damage by winter freezing of porous courses is illustrated.

Pavement Testing -- Before And After An Overlay, Herbert F. Southgate, Gary W. Sharpe, Robert C. Deen

Kentucky Transportation Center Research Report

A pavement scheduled for an overlay of 76 mm (3 inches) of asphaltic concrete on one half the project and 178 mm (7 inches) on the other half was tested and evaluated at two sites for each thickness of overlay. Precise elevations were obtained on 0.305-m (1-foot) intervals across the pavement. The Road Rater and Benkelman beam were used to determine the in-place behavior of the pavement before and after construction of the overlay. Prior to placement of the overlay, the pavements were cured to determine actual layer thicknesses, and in-place CBR tests were performed to determine actual subgrade conditions. …

Implementation Of Road Rater Deflection Testing For Pavement Evaluation And Overlay Design, Gary W. Sharpe, Herbert F. Southgate, Robert C. Deen

Kentucky Transportation Center Research Report

Road Rater deflection data were used to estimate the in-place subgrade strength and the in-place structural capacity of existing pavements. Pavement behavior can be expressed in terms of a reduced thickness of "reference" quality paving materials or as a reduced modulus of elasticity for the constructed thickness of asphaltic concrete. Mathematical relationships were developed making it possible to "program" the evaluation procedure (in modular form) for use with small hand calculators or minicomputers.

The pavement evaluation method has been successfully implemented in making recommendations for overlay designs for several pavement sections. Road Rater deflection data were used to estimate the …
