Evaluation Of The Water Quality Impacts Of Land Application Of Poultry Litter, T. C. Daniels, D. R. Edwards

Arkansas Water Resources Center Technical Reports

Evaluating the effect of land application of animal waste on water quality is fraught with inherent variability due to differing infiltration rates, slope, rainfall intensity and etc . Simulated rainfall technology has been used in erosion research for decades. Generally, this technology is used on plots of sufficient size (25 x 5 m) to develop rill and interrill erosion. The object of this investigation was to adapt and modify existing rainfall simulation technology used in soil erosion research for use in evaluating water quality impacts of land application of animal waste, and to test, evaluate and demonstrate it's scientific validity. …

Measurement Of The Effects Of Food Preparation Activities On The Microclimate Of The Snowball Dining Room Area Of Mammoth Cave, Kelly Kaletsky

Masters Theses & Specialist Projects

The stability of Mammoth Cave’s microclimate has never undergone extensive investigation. The Snowball Dining Room area was chosen to measure the microclimate of the cave and to determine if food preparation, human presence and surface temperature variations alter this microclimate. Three portable weather stations containing a temperature / humidity probe, datalogger and microbarograph were placed in various locations along three passageways leading away from the dining room. Readings were taken 24 hours per day for four months. Plotting temperature readings in graph form show a correlation between temperature of the passageway and distance from the dining room.

Fage Measurements Of Tropospheric Ho With Measurements And Model Of Interferences, Thomas M. Hard, A. A. Mehrabzadeh, C. Y. Chan, Robert J. O'Brien

Environmental Science and Management Faculty Publications and Presentations

Ambient HO measurements by low-pressure laser-excited fluorescence with chemical modulation, and supporting ozone and water-vapor data, are presented for periods in May and August 1987. The observed peak daytime ambient HO concentrations in Oregon are in the range (2.5 to 8) times106 molecules cm⁻³ and show small negative offsets due to photochemical interference. Direct measurements of the interference at fixed [O₃] give the dependence on ambient [H₂O] and on the modulating reagent [isobutane]. At ambient [O₃]=30 p.p.b. and 10 torr H₂O, with excitation and detection at a total pressure of 4 torr, the net interference is equal to [HO]=-1.3times10⁶ molecule …

Measurement Of Vocs Pollution From Recycling Petroleum Contaminated Soils In Hot Mix Asphalt Concrete, Yaoqing Chen

Theses

The petroleum contaminated soils (PCSs) due to leaking underground storagetanks are required to be removed and isolated in a designated area for proper treatment. Recently, a technique of recycle has been developed to incorporate PCSs into hot mixing asphalt (HMA) as a partial substitute for stone aggregate; the mixture then was used for road paving.

This study focuses on the estimation of the emission of volatile organic compounds from the process of mixing asphalt with PCSs and the contamination of ground water by paving the asphalt mixture made with PCSs. Eleven volatile organic compounds and total non-methane organic compounds emitted …

Thermal Oxidative Decomposition Of Chlorobenzene In A Tubular Flow Reactor, Jian Liu

Theses

The thermal reaction experiments of chlorobenzene decomposition were carried out in a tubular flow reactor in hydrogen and oxygen mixtures ranged from 1% to 5% at one atmosphere total pressure. Experiment temperatures were varied over a range of 590--640°C. Residence times ranged from 0.3 to 2.0 seconds.

It was found that the decomposition of chlorobenzene increased with both temperature and residence time. The oxidation of chlorobenzene occurred more rapidly when oxygen concentration was increased. 95% decomposition of chlorobenzene occurred at 620°C, O₂/H₂ = 5%, and two seconds residence time.

The major products were benzene and HCl, and …

A Survey Of Electronic Environmental Controllers, Richard S. Gates, Douglas G. Overhults, Larry W. Turner

Biosystems and Agricultural Engineering Faculty Publications

Sixteen commercially available electronic environmental controllers were evaluated. The units were classified according to enclosure type, analog versus microprocessor based control, power supply, sensors, alarms, control relays and triac output, interval timers, outside temperature feedback, and retail price. An assessment of these controllers indicated several critical limitations in the application of this technology.

The use of integrated controllers for animal production has the potential for substantial improvements in production efficiencies. If the limitations observed in the present controller technology, as represented by this sample, are addressed, industry acceptance of the technology can be accelerated. A uniform standard to address this …

Desert Bighorn Sheep And Riverboat Interactions In Cataract Canyon, Utah, Mark C. Stanger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I studied desert bighorn sheep (Ovis canadensis nelsoni) behavior and habitat use in response to boating activities during 1985. The percent of total observed time in attention behavior before the boating season, during the boating season, and while riverboats were< 0.8 km from bighorn sheep groups was 1, 1.4, and 12.2, respectively. Estimated energy expenditure did not significantly differ for high riverboat pressures (2 > 0.2) or seasonal comparisons (2 > 0.1). Habitat use significantly differed for proximity to the river, which was probably related to the summer use of the river for drinking. Moderate, minor, and no responses to passing riverboats were observed 3, 39, and 58%, respectively. Responses to riverboats did not significantly differ according to time of day (2 > 0.15) or …

Soil Heterogeneity And Its Exploitation By Plants, Robert B. Jackson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In this dissertation I first examine the ability of individual plants in the field to garner localized soil nutrients. I then measure actual soil variability around perennial plants and use various statistics to quantify the scale and degree of that variability.

Soil patches on opposite sides of Pseudoroegneria spicata tussocks were treated with distilled water or a nutrient solution containing N, P, or K in three field experiments. When P was augmented in the enriched soil patches, rates of P uptake increased significantly for roots from enriched patches compared with roots in control patches. Rates of ammonium and potassium uptake …

Efficacy Of Methyl Anthranilate As A Bird Repellent On Cherries, Blueberries And Grapes, Leonard R. Askham

Vertebrate Pest Conference Proceedings: 15th (1992)

Anthranilitic acid derivatives, used as common food additives, have been explored as bird repellent agents for a number of years. Research in this study show that methyl anthranilate, when exposed to the UV spectrum of sunlight, readily dissipates within 64 hours. The addition of surfactants and extenders did not appreciably alter the degradation curve, nor did they lessen the phytotoxic properties of the chemical.

Field trials under IR-4 guidance and support indicate that methyl anthranilate (MA) is an effective, biodegradable, nontoxic bird repellent. In formulation with a lipid molecular binding compound degradation of methyl anthranilate was extended from four to …

Cougar Attacks On Humans: An Update And Some Further Reflections, Paul Beier

Vertebrate Pest Conference Proceedings: 15th (1992)

I examined historical records of unprovoked attacks by cougars on humans in the U.S. and Canada during 101 years (1890-1990). There were 9 attacks resulting in 10 human deaths and at least 44 nonfatal attacks. In a recent paper, I listed these attacks and discussed them in considerable detail (Beier 1991). Although extremely rare, attacks on humans have increased markedly in the last 2 decades, during which cougar numbers and human use of cougar habitats have increased. There is no substantial evidence that habituation underlies this increase in attacks. The data provide weak support for the notion that an attacking …

Administrative Procedures And Contracts For Vertebrate Pest Programs, Bruce A. Colvin, Curtis A. Meininger, Michael J. Grealy

Vertebrate Pest Conference Proceedings: 15th (1992)

A proactive (rather than reactive) approach to rodent control includes effective planning, administration, and coordination. Centralized coordination, detailed scheduling, and well-defined contract specifications provide a solid basis for managing an integrated pest management program. Documentation and data management help to ensure cost effective and efficient operations. The ability to work with people and bureaucracies is essential for the science of rodent control to be applied effectively in real world situations and for vertebrate pest programs to succeed.

Development Of Rodent Control Technology For Confined Swine Facilities, Robert M. Corrigan, Cheryl A. Towell, Ralph E. Williams

Vertebrate Pest Conference Proceedings: 15th (1992)

This paper discusses the development of site-specific baiting technology for controlling the house mouse (Mus musculus) in confined swine facilities utilizing specific rodenticide formulations, bait stations, and baiting strategies. Behavioral research was also conducted to identify primary nesting and travel activities of mice within grower-finishing units. The rodenticide bromadiolone in a block formulation was found to be effective in most baiting trials, and provided resistance to the harsh environment of the swine facility and the necessary versatility for securing baits to minimize hazards to swine. A commercially available tamper resistant bait station was found to be effective for …

Coyote Control To Protect Endangered San Joaquin Kit Foxes At The Naval Petroleum Reserves, California, Brian L. Cypher, Jerry H. Scrivner

Vertebrate Pest Conference Proceedings: 15th (1992)

We investigated the effectiveness of a coyote (Canis latrans) control program implemented to increase numbers of endangered San Joaquin kit foxes (Vulpes macrotis mutica) at the Naval Petroleum Reserves in California (NPRC). Between 1980 and 1985, the kit fox population on NPRC declined approximately 66% while coyote abundance apparently increased. Coyote predation was identified as the primary cause of mortality for kit foxes. From 1985 to 1990, the U. S. Department of Energy (DOE) sponsored a program to kill coyotes with the objective being to reduce predation on kit foxes and increase fox numbers. Control methods …
