Investigation Of Benzo(A)Pyrene In Outdoor Air, Indoor Air And Personal Inhalation Air, Hsiu-Wen Chen

Theses

The assessment of human exposure to an environmental contaminant requires the measurement of the concentrations levels present in each pathway of possible contact.

This was an investigation of human exposure to an environmental pollutant, benzo(a)pyrene, in outdoor air, indoor air and personal inhalation air samples. The analytical procedure involved extraction by ultrasonic and separation by thin layer chromatography, and detection by fluorescence. The resulting data was used to develop a profile of indoor and outdoor human exposure to B(a)P during the year.

Thermal Decomposition Of Dichloromethane In Hydrogen/Oxygen/Argon Mixtures And In Pure Oxygen, Wen-Pin Ho

Theses

The thermal decomposition of Dichloromethane in hydrogen/oxygen mixtures and argon bath gas was carried out at 1 atmosphere total presure in tubular flow reactors of varied surface to volume (S/V) ratio. The thermal degradation of dichloromethane was analyzed systematically over temperature ranges from 610 to 820°C, with average residence times in range of 0.1 to 2.0 seconds. Five reaction sets in three different size flow reactors were studied.

It was found that the complete decay ( 99% ) of the dichloromethane at 1 second residence time occurs at about 810°C for all the reactants ratio sets. The major products for …

The Case Of Rose Island: An Example Of Conflicting Goals And Competing Jurisdictions In Coastal Zone Development, Thomas James Gibson

Marine Affairs Theses and Major Papers

The purpose of this paper is to investigate the methods and tactics employed at the local level by all of the participants in the resolution of a controversial coastal development issue. It is the author's goal to present a case study of a proposal that had progressed at least through the local level of the approval process and study the mechanism to see if it produces a socially desirable result. Resolution of the final form that the development of Rose Island will take is no closer today than it was in the Spring of 1986, so this paper necessarily has …

The Benefits Of Weaning Cattle In The Kimberley, David Pratchett, Stuart Young

Animal production and livestock research reports

The Kimberley region was populated with Shorthorn cattle from Queensland and New Sonth Wales in the 1880's. The descendants of these cattle known as Kimberley Shorthorn are still the predominant breed in the region. The relatively poor performance of these cattle under the harsh Kimberley conditions and the fact that changing the genotype can improve productivity was recently published (Pratchett D. WADA Journal No. 4 1988)

While the adoption of Bos indicus breeds is the correct move, improved husbandry can also increase the productivity of the Kimberley Shorthorn cow. The majority of cattle in the Kimberley are not weaned. Sometimes …

Total Maximum Daily Loads And Waste Load Allocations For Las Vegas Bay: Rationale And Calulations, State Of Nevada: Division Of Environmental Protection

Publications (WR)

In September 1987 the Nevada Division of Environmental Protection revised Water Quality Standards for Las Vegas Wash (LVW) and Lake Mead. Standards were set for chlorophyll-a and unionized ammonia in Las Vegas Bay (LVB) (NDEP 1987). The 1986 and 1987 LVB data showed non-achievement of both the chlorophyll-a and unionized ammonia standard which triggered an analysis of total phosphorus and total ammonia Total Maximum Daily Loads and Waste Load Allocations which are presented in this report. This report is separated into three sections: 1. 1987 Las Vegas Bay Water Quality Conditions and Seasonal Periodicity. 2. Concentration Estimates at Northshore Road …

Modeling Forest Dynamics Based On Stand Level Resource Allocation, Geoffrey Candler Poole

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An ecologically based model of forest succession is presented. In the model, trees compete for a share of limited growth resources available from their environment. Competition is reflected by each tree's effect on the resource pool and is not explicitly modeled. Model parameters were fit to field data from subalpine forests of the Rocky Mountains. A technique for estimating model parameters from understory-tolerance rankings and silvical characteristics of each species is also presented. The model's output was consistent with our current understanding of forest dynamics. Emergent properties of the model also mimicked natural processes such as self-thinning, release, and maximum …

Using Computer Imaging To Assess Visual Impacts Of Forest Insect And Disease Pests, Daniel Rabin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forest insect and disease pests alter the appearance of trees, thereby impacting visual resources. Because of the complexity of most forest landscapes, the degree of visual impact of pest-infested forest stands is difficult to quantify.

This paper describes a method of measuring visual impacts of pest-infested forest stands. Photographs of healthy Ponderosa pine trees were entered into a computer video-image-processing system. Using this system, images of trees were altered to simulate different degrees of infestation by limb rust, a forest pathogen.

The altered and unaltered images were shown to groups of observers who rated the scenes in terms of "scenic …

Root Exploitation Of Fertile Soil Microsites, Robert B. Jackson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Root exploitation of enriched soil microsites was examined for the tussock grasses Agropyron desertorum and Agropyron spicatum and the shrub Artemisia tridentata. Two mechanisms of exploitation of the microsites were examined: root proliferation and changes in nutrient uptake capacity. One day after nutrient solution was applied to small soil patches, the mean relative growth rate of Agropyron desertorum roots in enriched patches was two to four times greater than for roots of the same plants in soil patches treated with distilled water. This rapid and striking root proliferation occurred in response to N-P-K enrichment as well as to P or …

Management, Foraging Behavior, Diet Composition And Forage Quality Of Free-Ranging But Herded Camels In Ceeldheer District, Central Somalia, Ahmed A. Elmi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In Somalia, camel (Camelus dromedarius) survivability and milk production has been higher than for other domestic livestock and contributes substantially to the subsistence of Somali pastoralists. The objective of this research was to study management, foraging behavior and nutrition of camels in their natural habitat to determine how production continues under seasonal nutritional stress.

Management systems of Ceeldheer pastoralists are based on available natural pasture and water. The natural rotation grazing system maintained an ecological equilibrium in the District.

Pastoralists manipulate their herds to suit existing environmental conditions, family needs and labor availability for herding. In herd management, …

Habitat Use And Diet Analysis Of Breeding Common Barn Owls In Western Nebraska, Joseph A. Gubanyi M.S.

School of Natural Resources: Dissertations, Theses, and Student Research

I studied barn owl (Tyto alba) breeding biology in western Nebraska 1984-1986. I had greatest success capturing males (56% success) at night using trap doors at nest sites and females (91 % success) using hoop nets at nest sites during the day. Barn owls removed 16 of 23 tail-mounted radios. Eight birds were radio-tracked for 7-14.5 hours. The mean foraging range was 198 ha (32- 299 ha, n = 8) with < 1 % overlap among birds from adjacent nest sites. Field-tested telemetry error was high (mean displacements of radio-locations for 2 birds were 208 and 241 m). I found no relationship between percent cover in foraging habitat and reproductive success. I identified 10,140 prey items from 15 nest sites and found both annual and seasonal variation in barn owl diets. Microtus ochrogaster occurred most frequently (32.7%) and increased in the diet from 17.6 to 27.2 to 43.5% 1984-1986. M. ochrogaster and Perognathus hispidus annual frequencies were …

A Porpoise, Australophocaena Dioptrica, Previously Identified As Phocoena Spinipinnis, From Heard Island, Robert L. Brownell Jr., John Heyning, William Perrin

United States Department of Commerce: Staff Publications

Guiler, Burton and Gales (1987) reported a cranium (Tasmanian Museum No. A141 1) they identified as belonging to Burmeister’s porpoise, Phocoena spinipinnis Burmeister, 1865 from Heard Island (53°S 73°30’E). They noted that P. spinipinnis was previously known only from the cold-temperate coastal waters of South America and claimed that this cranium was evidence that the species has a much wider distribution than previously known. We have examined the photographs and details of their specimen and re-identify it here as Australophocaena dioptrica (Lahille, 1912) (family Phocoenidae).

Barnes (1985) listed several features that distinguish the skulls of species within the subfamily Phocoenoidinae …

Recent Improvements Of Water Quality And Biological Indicators In Hillsborough Bay, The Northeastern Section Of Tampa Bay, Florida, J.O. R. Johansson

Reports

The City of Tampa was implicated as a major point source polluter of Hillsborough Bay based on its release since 1951 of primary treated wastewater effluent into the bay. To alleviate nutrient loads into Hillsborough Bay, the City of Tampa upgraded its Hooker's Point facility to advanced wastewater treatment (AWT) with a 60 MGD capacity. The transformation from primary treatment to advanced was successive.

Relocation Of City Raccoons, Richard C. Rosatte, Charles D. Macinnes

Great Plains Wildlife Damage Control Workshop Proceedings

Twenty-four city raccoons were radio-collared and relocated 25-45 km north of the original capture site in Toronto, Ontario. Following release, extensive exploratory movements were noted with distances of 2-7 km being traversed per night. Home ranges for adult males (avg = 39 km²) and females ( avg = 72 km²) far exceeded juvenile ranges and areas utilized by raccoons in an urban setting. None of the raccoons returned to the original point of capture and mortality of the relocated raccoons approached 50% during the first 3 months following release

Plio-Pleistocene Glacial Deposits In Northeastern Nebraska: New Exposures And Interpretations, M. R. Voorhies, R. G. Goodwin

A field trip sponsored by the Nebraska Geological Society. Trip Leaders: Dr. M.R. Voorhies, University of Nebraska State Museum. & Dr. R.G. Goodwin, HWS Technologies Inc. Spring 1989

Recent interpretation of oxygen isotopic data for benthic and planktonic foraminifera recovered during ocean drilling programs suggest that world ice volume was greater than the ice volume of 18 thousand years ago (Late Wisconsinan) approximately 2.5 million years ago (Prentice and Matthews, Geology, November, 1988). This agrees well With biostratigraphic and paleoecologic interepretations drawn from sediment cores obtained from the Arctic Ocean Basin. The latter data suggest complete ice cover of the …

Red Swamp Crayfish Ecology In Lake Mead, Suzanne E. Leavitt, Jennifer Stephens Haley, Mikell Hager, Donald H. Baepler, Nevada Department Of Wildlife

Publications (WR)

Red swamp crayfish (Procambarus clarkii) were trapped in Flamingo Wash, an urban wash of Las Vegas, during four periods of 1988. Life history and reproductive success were determined. The trapped crayfish were marked and released into a study cove in Lake Mead as part of an experimental stocking program. Retrap data from the study cove were used to determine life history, habitat preferences, and movement patterns of the stocked crayfish. In addition, a literature search was done on red swamp crayfish ecology, including food preferences, life history, habitat preferences and fish predation.
