Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard

Masters Theses & Specialist Projects

The ability for wetlands to purify contaminated water is not a new concept. Natural wetlands have been cleansing water within our environment for ages. After studying the process of natural wetlands the same concept was applied to municipal waste. It is the success of constructed wetlands treating municipal waste that created the new idea for the application of a wetland system to treat wastewater from livestock facilities. Through proper design and management, constructed wetlands may be useful for reducing the nutrient concentration of waste (Rieck el al., 1996). Taking into consideration the higher nutrient loads of livestock waste, the same …

Canadian Cooperative Wildlife Health Centre: Newsletters and Publications

The Canadian Cooperative Wildlife Health Centre (CCWHC) was established in 1992 as an organization among Canada's 4 veterinary colleges, with a mandate to apply veterinary medicine to wildlife management and conservation in Canada. A major function of the CCWHC is nation-wide surveillance of wild animal diseases. Disease surveillance is conceived as consisting of 4 different activities: detection, diagnosis, information management, and use of information. In the CCWHC surveillance program, detection of disease is carried out by a wide range of professional and avocational field personnel, and much effort is expended to stimulate and support this activity. Diagnosis is done by …

Bulletin 4328 - Soil Testing For Vegetable Production On The Coastal Plain, Ian Mcpharlin, Murray Hegney

Bulletins 4000 -

Vegetable growers need to use fertiliser efficiently. Under-fertilising can reduce yield, which results in economic losses. Over-fertilising can reduce yield and contribute to nitrogen and phosphorus pollution of ground and surface waters. Concerns have been expressed that fertilisers applied to horticultural crops contribute to the phosphorus pollution of the rivers and estuaries of the west and south coast of Western Australia.

Soil testing is a technique that can be used by growers to make better fertiliser decisions. When soil tests show high levels of nutrients, growers can reduce fertiliser application for the current crop. This should enable growers to maintain …

Native Vegetation On Farms Survey 1996 : A Survey Of Farmers Attitudes To Native Vegetation And Landcare In The Wheatbelt Of Western Australia, Suzanne Jenkins

Resource management technical reports

The Native Vegetation on Farms survey 1996 was performed to assess the attitudes of farmers to a number of issues related to existing native vegetation on farmland, the replanting of vegetation on farms and land degradation. Research has shown that it is important for a proportion of all farmland to have some native vegetation for ecological stability, to regulate hydrological processes and for long-term sustainability of farm production.

Channel Narrowing Of The Green River Near Green River, Utah: History, Rates, And Processes Of Narrowing, Tyler M. Allread

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous scientific research has documented channel narrowing on the Green River near Green River, Utah, but the exact timing, rates, and causal mechanisms of that narrowing have been the source of disagreement in the scientific literature. This thesis demonstrates that the Green River has narrowed in two separate periods during the last 100 years. The narrowing is driven primarily by changes in the hydrologic regime and not by the invasion of saltcedar. The channel narrowed between 1930 and 1938, when a shift from wetter than normal conditions to a period of draught led to a reduction in river discharge. Channel …

Study On The Parasites Of Falcons In The United Arab Emirates, Mohammad Ismail M. A Sultan Al-Ulama

Theses

Sakers Falco cherrug, Gyrfalcons Falco rusticolus, Peregrines Falco peregrilllls, in addition to Hybrids (saker X gyrfalcon, or gyrfalcon X peregrine), were found to be the most popular species of falcons in United Arab Emirates (UAE).

The importance of falcons and falconry in Arabia was highlighted with a brief history of falconry in Arabia.

The study focused on the prevalence of intestinal parasites (coccidia, helminthes and nematodes) and blood parasites (Haemoproteus sp. and Leucocytozoon sp.) as well as ecto-parasites (Ticks and Mites) of these falcons, with discussion on the possible sources of infection in view of the …

The Geomorphic Basis Of Colorado Squawfish Nursery Habitat In The Green River Near Ouray, Utah, Cynthia L. Rakowski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nursery habitat availability is considered a bottleneck to successful recruitment of Colorado squawfish (Ptychocheilus Lucius). Detailed geomorphic studies were conducted in a 1.5-km reach to examine channel response to flows and the geomorphic setting of nursery habitats during a 2-year period. Videography was used to extend relationships in the 1.5-km reach to a longer 10-km reach.

Nursery habitat availability varied yearly with little persistence in location or geomorphic setting of individual habitats for the 2 years of this study. A small number of habitats provided most of the area of high-quality (i.e., deep) habitat, and most of the …

Effects Of Flow Augmentation On Channel Morphology And Riparian Vegetation In The Upper Arkansas River Basin, Colorado, Dewitt S. Dominick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined historic change of riparian plant communities and fluvial geomorphic response of gravel-bedded streams and their floodplains to over 50 years of hydrologic disturbance. Four tributary basins of the Arkansas River were analyzed. Lake Creek, Clear Creek, and Cottonwood Creek are drainages similar in area, physiography, and vegetation composition. However, Lake Creek may receive an instantaneous discharge of approximately 28 m3sec^-1 from the Twin Lakes tunnel, over three times the normal flow of the stream during spring runoff. By contrast, Clear Creek and Cottonwood Creek, nonaugmented streams, were used as controls to compare the historic and present …

Post-Middle Miocene Geologic History Of The Tualatin Basin, Oregon With Hydrogeologic Implications, Doyle Coley Wilson

Dissertations and Theses

The geologic history and sedimentary till of the Tualatin Basin after Columbia River Basalt Group (CRBG) emplacement is assessed and related to groundwater characteristics. The 334 m deep HBD-1 core from the Hillsboro Airport, provides the primary information for sediment characterization and is supported by over 2400 well logs and cores, and four seismic lines. The sedimentary section above the 26 m thick paleosol on the CRBG in HBD-I is divided into two main groups: a 25 m thick section of Missoula flood sediments called the Willamette Silt overlies a 263 m thick finegrained sequence of fluvial Neogene sediments.

Effects Of Acid Mine Drainage On Stream Fish Assemblages In The North Chickamauga Creek Watershed, Tennessee, Kristie J. Jenkins

Honors Theses

Approximately 18 miles of the NCC system, Tennessee is polluted by acid mine drainage (AMD). The effects of AMD upon the North Chickamauga Creek (NCC) system were evaluated from water quality measurements, habitat assessments, and fish collections. Sampling surveys were conducted at three AMO-impacted (pH < 5.5) and two reference sites (pH> 6.2) in the NCC system. Stream fish were collected using backpack electroshockers and hoop nets. A total of seven species were collected at the reference sites, whereas three species were collected at the AMO-impacted sites. Fish abundance was significantly greater (P < 0.1) at the reference sites than at the AMO-impacted sites, regardless of the sampling technique. No fish were collected at one of the AMO-impacted streams where the pH was <5 and the concentration of dissolved aluminum was > 700 mg/L. Results of my study indicate that fish populations were affected more by …

Las Vegas Wash Water Quality Monitoring Program: 1996 Report Of Findings, Richard A. Roline, James J. Sartoris, U.S. Bureau Of Reclamation, U.S. Geological Survey

Publications (WR)

Las Vegas Wash, a natural wash east of the city of Las Vegas, Nevada, carries stormwater, groundwater drainage, and sewage effluent from three sewage treatment plants to Lake Mead. The Wash provides nearly the only surface water outlet for the entire 2,193 mi² of Las Vegas Valley. A drainage area of 1,586 mi² contributes directly to the Wash through surface flow which is channeled to Las Vegas Bay of Lake Mead, while drainage of the remaining 607 mi² is presumably subsurface and may drain toward Las Vegas Wash.

In the 1930's and 1940's, sewage treatment plants were …

JOHN WgW Volume 7, Number 2 NEW MUIR Spring 1997 X I 4 J^,AN EPISODE IN THE YOSEMITE: by Frank E. Buske copyright @ 1989,1991, by Frank E. Buske (Editor's note: Dr. Frank Buske, emeritus professor and former Chair of the English Department at the University of Alaska, Fairbanks, now lives in Tucson, Arizona. This paper was presented at the 1990 John Muir Conference at UOP, and is published here, along with letters from a private collection, with the author's permission.) ('•< Muir spent the winter of 1873-75 at the McChesney home in land, having come down from his beloved mountains to spend time putting into words some of the observations he had made • ■ nig the trees and the glaciers and on the ■ - les. Mrs. Jeanne Carr and others of his I «ls had, for a long time, been * •imaging him to do more writing; they HHgested that there was a market for his j I les and a need for him to set down his ilf|overies while they were still fresh in his mind. Mrs. McChesney, in a later reminiscence, described Muir as "dressed gi»iei ally in what we call now negligee, i.e., he wore a blue flannel shirt, but was never : without a sprig of some green plant as an-S*0 jjpment." Muir's apparel would be appropriate for ij§krnd of life he most enjoyed. He disliked lifting to dress for any formal occasion and hied to avoid any social gathering that would HHuire clothing and behavior that were not comfortable to him. Although he had uently written of his loneliness, sped1 w.f t enviously about his relatives and ids who had married and were raising families, he seems to made no effort to alter his own bachelor status during that Winter in the Bay Area. Mrs. J "• ' Carr The subject of John Muir and his relationship with women is interesting to ponder, and is a topic that has received a good deal of attention and even more misinformed speculation. Some verses that he wrote before this time, highly critical of young women, their appearance and the way they dressed, prompted his friend, Bradley Brown, to write the eighteen-year old Muir, "Excuse me, John, but perhaps unreciprocated love was the cause of your rhyming against the sweet little creatures. To love is painful, that is true. Not to love is painful, too. But oh! It gives the greatest pain to love and not to be loved again." The subject of Muir's poem may well have been imaginary but Brown's observations can certainly be considered prescient. At twenty-two, in Prairie du Chien, Wisconsin, working with ice-boat inventor Wiard, John Muir wrote his brother, David, telling him of the people he was meeting. David, very much a ladies' man, replied, "I would like very well to hear that piano and Miss E.P. (excuse me, John) playing on it." Miss E.P. was, of course, Emily Pelton, niece of the proprietors of the Mandell House where Muir was living. In December of that same year, John Muir wrote his sister, Sarah, and her husband, David Galloway, of an occasion which shows a rather vivid picture of his social skills: UNIVERSITY OR page 1 (continued on page 3) PACIFIC

State Of The Fisheries Report 1995/1996, Jim W. Penn

Status Reports of the Fisheries and Aquatic Resources

The State of the Fisheries document is designed as an essential supplement to the Annual Report to Parliament. By summarising data such as landings, effort, catch rates, stock assessment and breeding stock levels, this document provides a valuable reference point for all Western Australian fisheries of major importance to the commercial, recreational and aquaculture sectors. The report indicates that overall the major fish stocks which support fisheries in Western Australia are in a reasonably healthy condition. Those species which are being harvested at levels above their optimum, such as the shark stocks, are subject to increasing fishing controls designed to …

Critical Evaluation Of The Double Tracks Remediation Project, Craig J. Barnes

UNLV Theses, Dissertations, Professional Papers, and Capstones

The U.S. Atomic Energy Commission (AEC) (now the U.S. Department of Energy), in testing the safety of nuclear weapons under many different conditions, detonated single plutonium bearing devices in such a fashion as to simulate an unintentional detonation of the high-explosive portion of nuclear weapons. This resulted in the uncontained spread of plutonium and other radionuclides, such as americium and depleted uranium, in the environment in the vicinity of these experiments. The Double Tracks site was one of these experiments on the Tonopah Test Range (TTR) which was contaminated hi excess of 200 picocuries per gram (pCi/g). The Double Tracks …

The Eldorado Landfill: A Case Study, Heather A. Nash

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1995, Boulder City bought from the federal government 167 square miles of land in the Eldorado Valley which is located approximately seven miles west of the city. Soon afterward, the current landfill in Boulder City began accepting construction waste from Las Vegas. The large dump trucks had to travel through Boulder City on route to the landfill. In doing this they passed through three school zones and residential areas. When residents began complaining about the trucks, the Boulder City City Council began investigating various ways to solve the problem. The solution they adopted was to construct a new landfill …

Acid Mine Drainage And Its Effects On Salamander Assemblages In Cumberland Plateau Streams Of The North Chickamauga Creek Watershed, Tennessee, Melissa Combs

Honors Theses

In Appalachia's coal mining regions, acid mine drainage (AMD) has contributed to the widespread degradation of stream ecosystems. Salamanders are common inhabitants of healthy headwater streams and because of their permeable skins are excellent indicators of ecosystem intergrity. Hence, we investigated the potential effects of AMD on the species richness and relative abundance of aquatic salamanders in selected stream reaches (sites) of the North Chickamauga Creek (NCC) system, Tennessee. Specimens were collected by kick-net sampling with a 500um mesh dip net and/or electroshocking at four AMD-impacted sites (pH< 5.6) and two reference sites pH> 6.2), May-July 1996. Species richness was similarly low at reference sites, 2 …

Ichthyofaunal And Habitat Associations Of Distinct Populations Of Southern Redbelly Dace, Phoxinus Erythrogaster (Teliostei: Cyprinidae) In Mississippi, Martin O'Connell

Earth and Environmental Sciences Faculty Publications

Twenty-two field sites in W-central Mississippi were surveyed for southern red- belly dace Phoxinus erythrogaster to characterize habitat and ichthyofaunal associations of these 'endangered' disjunct populations. Phoxinus erythrogaster occurred at only six sites. Data assessed similarity among all sites and described microhabitat associations of P erythro- gaster. Five species, including Semotilus atromaculatus, Campostoma anomalum, Etheostoma whipplei, P erythrogaster and Pimephales notatus, comprised 95% of the total number of in- dividuals collected at P erythrogaster sites. Standardized abundance (number per seine haul) for S. atromaculatus was consistently high among all P erythrogaster sites, whereas standard- ized abundance for C. anomalum, P …

Development Of A Fluorescent Indicator For Inorganic Monochloramine, Xiaojun Dong Zou

Chemistry & Biochemistry Theses & Dissertations

Current methods used to determine combined residual chlorine cannot distinguish between inorganic monochloramine (NH₂Cl) and organic chloramines. Studies described in this thesis were carried out to develop a novel method of determining the concentration of inorganic monochloramine in aqueous solutions. Based on the observation that the reaction of 3-formyl-1-methylpyridinium chloride (3FMPCl) with NH₂Cl produces a solution which is fluorescent, experiments were conducted to characterize the reaction and optimize the experimental conditions. Using the finalized protocol, NH₂Cl measurements were made in the presence and absence of organic amines and compared with a commonly used N, …
