The Effect On Australian Animals Of 1080-Poisoning Campaigns, John C. Mcilroy

Vertebrate Pest Conference Proceedings: 15th (1992)

Animals in Australia vary greatly in their sensitivity to 1080 poison, with known LD_50’s ranging from 0.11 to over 800 mg kg ^-1. Many native species, particularly in western Australia, have evolved tolerances to 1080 through ingestion of native plants that contain fluoroacetate or prey that consume those plants. Despite this, some native species, particularly a few herbivorous mammals, birds and rodents, could be poisoned during control campaigns against vertebrate pests. Field studies indicate that poisoning campaigns are not significantly affecting populations of common non-target animals, but further impact studies are required on vulnerable, rare, endangered, or uncommon …

Rodent Damage In Hawaiian Macadamia Orchards, Mark E. Tobin

Vertebrate Pest Conference Proceedings: 15th (1992)

Roof rats (Rattus rattus) damage an estimated 5-10% of the annual macadamia nut crop in Hawaii, resulting in farm value losses of between $2-4 million. The Denver Wildlife Research Center field station in Hilo, Hawaii studies the biology, impact, and control of rodent pests in Hawaiian agricultural crops. This paper describes field and laboratory research currently being conducted to address rat problems in macadamia nut orchards.

Evaluation Of Methyl Anthranilate As A Bird Repellent In Fruit Crops, Michael L. Avery

Vertebrate Pest Conference Proceedings: 15th (1992)

Methyl anthranilate (MA) is a grape-flavored food additive that is aversive to birds. Previous studies had indicated that anthranilates can deter frugivorous birds but that anthranilates are phytotoxic. In this study, I tested the bird repellency to 2 MA formulations on blueberry plants in a large flight pen. Neither MA formulation protected the blueberries from damage by cedar waxwings (Bombycilla cedrorum) or European starlings (Sturnus vulgaris). The encapsulated formulation, however, was nonphytotoxic. Due to the on-going need for safe bird deterrent compounds, further development and testing of MA as a bird repellent on fruit is warranted. …

Multilayer Perceptrons For Classification, Lisa M. Belue

Theses and Dissertations

Techniques for training, testing, and validating multilayer perceptrons are thoroughly examined. Results obtained using perceptrons are compared and contrasted with two multivariate discriminant analysis techniques- logistic regression and k neighbor. Methods for determining significant input features are investigated and a procedure for examining the confidence to place in the significance of these features is developed. Procedures to evaluate the applicability of high-order feature inputs are examined. These methods and procedures are applied to two very different applications. The first application concerns the prediction of Air Force pilot retention/separation rates for input to force projection models. The second application concerns the …

Chemical, Biological And Machinery Aids For Quality Haymaking, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Hay and pasture crops are critical to Kentucky Agriculture and to that of the entire temperate region of the US. The sale of cattle, calves and dairy products provide 29% of Kentucky's farm income compared with 23% for tobacco. Beef cow-calf enterprises comprise the majority of cattle numbers in the state, however, dairy production is also significant. A substantial horse industry exists in Kentucky which is an excellent market for high quality alfalfa hay. At present a substantial amount of alfalfa for horse feeding in the state is imported.

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Vaughn M. Bryant Jr.

School of Natural Resources: Faculty Publications

The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …

Reconnaissance Survey Of Nitrate Concentrations In Ground Water In Howard And Pike Counties, Arkansas, Travis Thornton, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

In recent years, the rapid growth of poultry and hog production in Arkansas has caused concern regarding nitrate contamination of the ground water. In the study area of Pike and Howard Counties, the number of hogs has increased from 3,300 hogs in 1970 to 75,000 hogs in 1990. Poultr¥ production for the area has increased from 38,933,000 per year 1n 1970 to 62,774,000 per year in 1990. As animal production increases, so does the amount of animal waste that must be disposed. Hog production is of particular concern. Typical hog operations store concentrated animal waste in lagoons prior to land …

Determining The Chemical Composition Of Cloud Condensation Nuclei, Allen L. Williams, Jane E. Rothert, Kent E. Mcclure, Darryl J. Alofs, Donald E. Hagen, Daniel R. White, A. R. Hopkins, Max B. Trueblood

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This second progress report describes the status of the project one and one-half years after the start. The goal of the project is to develop the instrumentation to collect cloud condensation nuclei (CCN) in sufficient amounts to determine their chemical composition, and to survey the CCN composition in different climates through a series of field measurements. Our approach to CCN collection is to first form droplets on the nuclei under simulated cloud humidity conditions, which is the only known method of identifying CCN from the background aerosol. Under cloud chamber conditions, the droplets formed become larger than the surrounding aerosol, …

Attempts To Demonstrate Reductive Dechlorination Of Chlorobenzenes By Anaerobic Microorganisms, Melissa S. Gross

I. Removal Of Chromium From A Highly Contaminated Soil/Slag Matrix By Soil Washing At Low Ph, Ii. Removal Of Chromium From Impregnated Clay Matrices By Soil Washing At Low Ph, Erez Gotlieb

Theses

Section I. Chromium is a major soil contaminant of industrial sites in New Jersey, as well as in many of the Superfund sites throughout the United States. Removal of chromium by soil/slag washing with low pH sulfuric acid solutions is described. The extraction parameters are acid concentration, contact time, temperature, solvent/soil ratio, and acid type. The effect of two-stage extraction is discussed.

Soil/slag washing with sulfuric acid concentrations of 2% weight:volume (units are g/ml. This concentration is approximately equal to 0.4 N) at 75:1 v:w solvent/soil ratios yielded chromium extraction efficiencies of 95%, but 50% of the soil matrix was …

Immobilization Of Heavy Metals In Incinerator Ash Using A Microbiological System, Gordon Hinshalwood

Theses

The heavy metals contained in incinerator ash constitute an environmental hazard because they can be leached out of the ash matrix by rain water after the ash is landfilled. This study focused on a novel biological treatment process in which immobilization of the heavy metal content of incinerator ash is achieved using naturally occurring microorganisms. Specifically, immobilization was obtained by the use of a sulfide producing bacteriological system. The genus Desulfovibrio was cultured under anaerobic conditions, providing a source of sulfide from the reduction of sulfate as a natural metabolic function. The sulfide produced then formed highly insoluble precipitates with …

Kinetics Of Phenol Biodegradation By Pseudomonas Resinovorans (Atcc 14235), Susmita Guptapal

Theses

The kinetics of phenol biodegradation were studied by using a pure culture of Pseudomonas resinovorans (ATCC 14235). Experiments were performed in shaker flasks and samples were analyzed for biomass content (based on optical density), and for phenol concentrations (based on HPLC measurements). The experimental data indicated that phenol is an inhibitory substrate at high concentrations. Specific growth rate data were fitted to an Andrews' expression with good success. The regressed kinetic constants were also used in predicting phenol biodegradation as a function of time. It was found that predicted and actual experimental values were close at least for the first …

Partial Characterization Of The Major Lipooligosaccharide From A Strain Of Haemophilus Ducreyi, The Causative Agent Of Chancroid, A Genital Ulcer Disease, William Melaugh, Nancy J. Phillips, A A. Campagnari, R Karalus, B W. Gibson

Chemistry Faculty Publications

The first preliminary structure of a surface lipooligosaccharide from Haemophilus ducreyi has been determined. The major oligosaccharide was released by mild acid hydrolysis and analyzed by liquid secondary ion and tandem mass spectrometry. The mass spectral data combined with composition and methylation analysis yielded the most probable structure; Gal1----4GlcNAc1----3Gal1----4Hep1----6Glc1----( Hep1----2Hep1----)3,4Hep1---- KDO, where the reducing terminal 3-deoxy-D-manno-octulosonic acid (or KDO) exists in an anhydro form. This anhydro species results from the elimination of a phosphate from C-4 of KDO during mild acid hydrolysis. The core heptose trisaccharide consists of L-glycero-D-manno-heptose, but analysis of the peracetylated sugars indicated that the 1,4-linked heptose …

Track Structure Model Of Cell Damage In Space Flight, Robert Katz, Francis A. Cucinotta, John W. Wilson, Judy L. Shinn, Duc M. Ngo

Robert Katz Publications

Cell damage by high linear energy transfer (LET) radiations has been described by a phenomenological model (track theory) for more than 20 years. With track theory, molecules of biological significance (dry enzymes and viruses) act as one-hit detectors. Recent additions to tire class of one-hit detectors arc Escherichia coil B, and single- and double-strand breaks in SV-40 virus in EO buffer, where indirect effects predominate. The response of cells (survival, transformation, and chromosome aberration) to these radiations is typically described by a four-parameter model whose numerical values are determined from the equations of the theory being fit to experimental …

The Impact Of Total Employee Participation In An Experience-Based Training And Development Program, Or Corporate Adventure Training Program, On The Corporation's Work Climate, Simon Priest

Research in Outdoor Education

Experience-based Training and Development (EBTD) or Corporate Adventure Training (CAT) has had a short history of usage and a long history of problems· with its credibility. Proponents of EBTD/CAT have claimed it was an effective and appropriate way to build teams, develop individuals and improve companies. They stated their case on a moderate collection of personal anecdotes and testimonies. Opponents of EBTD/CAT have claimed it was a sham, like many of the group oriented encounter techniques of the sixties. They cemented their opinion by pointing to a clear lack of research evidence, failing to substantiate the impact of such programs. …

Reply To Valverde, Paul B. Thompson

RISK: Health, Safety & Environment (1990-2002)

Professor Thompson responds to Valverde's argument, in the last issue, that his approach to Risk puts too much emphasis on the distinction between Risk subjectivism and Risk objectivism. In doing so, he asserts, inter alia, that anchoring Risk judgments in a probabilistic framework does not go far enough in rejecting reigning Risk-analysis notions of "real Risk."

Charles Rueben Keyes And The History Of Iowa Archaeology, William Green

Journal of the Iowa Academy of Science: JIAS

Charles Reuben Keyes (1871-1951) achieved recognition during his lifetime as the "founding father" of Iowa archaeology, and later assessments confirmed and reemphasized Keyes' stature as Iowa's pioneer archaeologist. The collections and documents Keyes compiled, his interpretive publications, and the records of field work he coordinated have proven more valuable to Midwest and Plains archaeology every year. This article emphasizes Keyes' involvement in the development of professionalism in American archaeology and Iowa’s position in the growth of the discipline from 1920 to 1950. Keyes' contacts with the principal archaeologists of his era ensured Iowa’s involvement in the development of survey methods …

Achieving Total Compensation For Injuries To Coastal And Marine Resources: The Evolution Of Current Valuation And Compensation Methodologies, Marian Toon Mcphaul-Chester

Marine Affairs Theses and Major Papers

Economists have developed numerous theories to calculate the total value of natural resources. These methods have been developed and applied over the last two decades. They continue to be refined through application and critique. Resource economists monetarily quantify the values which humans attach to coastal and marine resources. These valuation theories are the subject of much controversy in natural resource damage litigation. An understanding of the evolution of these damage provisions from the early common law actions to the current statutory remedies is essential those involved in coastal planning, management and litigation. This paper reviews these economic theories and the …
