Some risk due to the contamination of workplace environments is an inevitable part of human lives. These risks can often be reduced by improving the control of environmental pollution in the workplace. An extremely important challenge for any industry is to develop a mechanism to identify acceptable levels of safety, or "acceptable risk" in the workplace for specific situations, and to assure adequate quality control over measured or calculated exposure concentrations and their possible contributions to adverse health effects.

Recent understanding about system dynamics and predictability that has emerged from the study of complex systems is creating new tools for modeling interactions between anthropogenic and natural systems. A range of techniques has become available through advances in computer speed and accessibility and by implementing a broad, interdisciplinary systems view.
Analytical Modeling Of Aquifer Decontamination By Pulsed Pumping When Contaminant Transport Is Affected By Rate-Limited Sorption And Desorption, Thomas A. Adams, Robert C. Viramontes
Analytical Modeling Of Aquifer Decontamination By Pulsed Pumping When Contaminant Transport Is Affected By Rate-Limited Sorption And Desorption, Thomas A. Adams, Robert C. Viramontes
Theses and Dissertations
This research explores radially convergent contaminated transport in an aquifer towards an extraction well. This thesis presents the equations governing the transport of a contaminant during aquifer remediation by pulsed pumping. Contaminant transport is assumed to be affected by radial advection, dispersion, and sorption/desorption. Sorption is assumed to be either equilibrium or rate-limited, with the rate-limitation described by either a first-order law, or by Fickian diffusion of contaminant through layered, cylindrical, or spherical immobile water regions. The equations are derived using an arbitrary initial distribution of contaminant in both the mobile and immobile regions, and they are analytically solved in …
Migration And Dispersal Of Laughing Gulls In The United States, Jerrold L. Belant, Richard A. Dolbeer
Migration And Dispersal Of Laughing Gulls In The United States, Jerrold L. Belant, Richard A. Dolbeer
United States Department of Agriculture Wildlife Services: Staff Publications
The 3662 recovery records for Laughing Gulls (Larus atriczlla) banded in North America from 1924 to 1991 were analyzed to determine migration and dispersal patterns for Northeast (Maine to Virginia) and Gulf Coast (west coast of Florida to Texas) populations. Autumn migration for Northeast Laughing Gulls was initiated in October. Northeast Laughing Gulls migrated greater distances and were recovered farther south during winter than Gulf Coast gulls. Significantly more Gulf Coast Laughing Gulls wintered along the Gulf Coast than did Northeast Laughing Gulls. In contrast, significantly more Northeast Laughing Gulls wintered in Central and South America. Adult Laughing Gulls returned …

Toward Conservation Of Midcontinental Shorebird Migrations, Susan K. Skagen, Fritz L. Knopf
United States Department of Agriculture Wildlife Services: Staff Publications
Shorebirds represent a highly diverse group of species, many of which experience tremendous energy demands associated with long-distance migratory flights. Transcontinental migrants are dependent upon dynamic freshwater wetlands for stopover resources essential for replenishment of lipid reserves and completion of migration. Patterns of shorebird migration across midcontinental wetlands were detected from migration reports to American Birds and information provided by U.S. Fish and Wildlife Service national wildlife refuges. Patterns in species composition and abundance varied geographically, emphasizing the uniqueness of different regions to migrating shorebirds. Smaller species and neotropical migrants moved primarily across the Great Plains, whereas larger species and …

Guidance For The Development Of Air Force Storm Water Sampling Programs, Jerry K. Weldon Iii, Roy T. Willis
Theses and Dissertations
The purpose of this research was to develop sampling guidance that will enable Air Force (AF) installations to conduct cost effective storm water sampling in accordance with current storm water regulations. Data on the techniques used by AF bases to obtain storm water samples for the AF group storm water permit application were collected and analyzed. This information was used to outline management and resource requirements associated with the implementation of NPDES storm water regulations. The use of in-house personnel, automatic sampling equipment, or a contractor to perform the field data collection was examined. An in-house manual approach to storm …

Animal Welfare And The Statistical Consultant, Richard M. Engeman, Stephen A. Shumake
United States Department of Agriculture Wildlife Services: Staff Publications
Animal welfare considerations and regulations serve to ensure that experimental animals are used wisely while minimizing stress. Substantial impacts on the use of animals in experiments have resulted, thereby increasing the challenges for designing studies and analyzing data to provide valid inferences. Statisticians should become more indispensable for involvement in study design (including Animal Care and Use Committees), application of appropriate analyses, prudent interpretation of results, and the development of new statistical techniques to meet these needs.

Arkansas Water Resources Center Technical Reports
Since the beginning of the Arkansas Water Resources Center the overall program has been focused on helping local, state and federal agencies learn to manage Arkansas' water resources. AWRC has contributed substantially to the State's water resources via research and training of students. Through the years, projects have included topics concerned with irrigation, ground water modeling, non-point source pollution (including sediment erosion), water quality, efficient septic tank design, and ecosystems. Information on water research and other water-resource information is disseminated by the Center through public presentations, conferences, and publications. Since 1980, an average of more than 15 principal investigators a …

Determination Of The Efficacy Of Fertilization Practices On Bob Kidd Lake, Richard L. Meyer, Jeanette K. Shipley-Phillips
Arkansas Water Resources Center Technical Reports
Fertilization strategies have been used as a standard practice on Bob Kidd and other lakes and reservoirs to enhance the availability of phytoplankton and zooplankton as food sources for developing fish. The nominal practice is to use a fixed application rate and a constant ratio of nitrogen and phosphorus fertilizer per acre of lake surface. The application technique varies as does the timing. Application techniques vary from spillage and bulk deposition of fertilizer at selected sites to broadcasting of pellets or a pre-mixed slurry via boat and/or airplane. Timing is usually in the spring under appropriate weather conditions.

The Influence Of Reservoir Basin Morphometry On Phytoplankton Community Structure, Richard L. Meyer, G. Keith Trost
Arkansas Water Resources Center Technical Reports
The research protocol was designed to compare three reservoirs with similar physical environments but different morphometry. Three reservoirs on the western edge of the Ozark uplift were selected because of their similar substrate and climatic condition. The reservoirs primarily differed in morphometry. Two of the reservoirs were of identical size, Bob Kidd and Prairie Groves Lakes, but of different configuration, semicircular and linear, respectively. The bifurcated lake, Lincoln Lake, was of smaller size. Each lake is dimictic. Each of the lakes were nitrate-N limited while soluble reactive phosphorus-P is available and not restricting the growth of phytoplankton. Although the pattern …

Wildlife Conservation and Management
The status of black bears in North America ranges from pest to threatened. The species appears relatively secure throughout most parts of its range except the southeastern coastal plain; in this region a number of disjunct populations exist on primarily publicly owned lands. Concern over the status of Ursus americanus luteolus led to a petition to list this subspecies under the Endangered Species Act. The Endangered Species Act is arguably the most important wildlife legislation in recent years. However, applying this valuable, but young, untested, and evolving legislation to the black bear subspecies is judged unwarranted and premature because of …
