Composting Of Explosives Contaminated Soil Using The White Rot Fungus Phanerochaete Chrysosporium, Michael J. Mcfarland, Shashi Kalaskar, Eric Baiden

Reports

Bioaugmentation using the white rot fungus Phanerochaete chrysosporium was found to be effective in enhancing TNT removal in lightly (i.e., below 100 mg/kg) contaminated soil. The percent reduction in TNT increased from 15% to 53% when soils were treated with fungal inoculated organic material. Maximum removal rates improved from 0.33 mg TNT/kg-day to 0.76 mg TNT/kg-day during the same treatment. Neither fungal inoculation nor organic amendment addition resulted in improving TNT removal kinetics in highly contaminated soils (i.e., above 1000 mg/kg). Executive Summary: Laboratory scale compost studies were conducted to evaluate the effect of bioaugmentation with the white rot fungus,

Nebraska's Rainwater Basin (RWB) wetland area is identified by the North American Waterfowl Management Plan (NAWMP) as a waterfowl habitat area of major concern in North America. The Rainwater Basin area is recognized as the focal point of a spring migration corridor used by millions of ducks and geese annually (Figure 1). This migration corridor is shaped like an hourglass, with the Rainwater Basin and Central Platte River located at the constriction.

Development And Standardization Of A Short-Term Assay For Evaluating Polluted Estuarine And Coastal Environments: The Medaka Embryo-Larval Assay, Michael Frederick Helmstetter

OES Theses and Dissertations

The eggs of the Japanese medaka (Oryzias latipes) were employed in a number of studies to develop a routine, standardized assay which can assess the acute and sublethal impacts of individual toxicants and complex mixtures. The eggs of this Cyprinodont minnow were topically treated with each toxicant or mixture dissolved in membrane permeable dimethylsulfoxide (DMSO) solvent. Nine chemicals were initially evaluated with two, pentachlorophenol (PCP) and tributyltin chloride (TBTCl), subsequently selected for extensive evaluations of salinity tolerance and the accuracy of the topical exposure method for representing a typical immersion exposure. The amount of material actually penetrating the eggs was …

Studies Of Ecological Factors That Affect The Population And Distribution Of The Western Gray Squirrel In Northcentral Oregon, Susan Ann Foster

Dissertations and Theses

The western gray squirrel (Sciurus griseus griseus Ord) occur only in the Pacific states and in a small corner of extreme western Nevada. Field studies of aspects of the ecology of the most widely distributed subspecies of western gray squirrel (S. griseus) were conducted at three sites in the ponderosa pine-Oregon white oak zone on the eastern slopes of Mt. Hood, Wasco County, Oregon, between 1981 and 1989. From 1981 through 1987, a Hunter Cooperation Program provided remains of squirrels shot during the annual late summer-early autumn hunting season. Other data were gathered through capture and release studies, radiotelemetry, and …

Zooplankton Community Abundance And Diversity In Dardanelle Reservoir, Arkansas, 1981-1990, John D. Rickett, Robert L. Watson

Journal of the Arkansas Academy of Science

Zooplankton samples were collected quarterly from five stations representing the discharge bay and four "control" or "dispersing impact" stations. Rotifers dominated all samples numerically and by the number of taxa. All major groups (Rotifera, Cladocera, Copepoda, and Protozoa) exhibited greatest abundances during the summer. Quarterly variations in abundance and number of taxa were documented. Except for an increase in taxonomic analysis detail between 1981 and 1984 resulting in several more taxa added to the list, no long-term increases, declines or repeating cycles were apparent. Margalef's Richness Index reflected this change and showed a long-term increase with evidence of a 5- …

How Stubble Affects Organic Matter, Plants And Animals In The Soil, Judy Tisdall

Journal of the Department of Agriculture, Western Australia, Series 4

Cereal yields have not increased greatly in Australia over the past 30 years and they are still only about half the potential determined by rainfall. One of the reasons for these low yields is our fragile soils, worsened by traditional systems of tillage and the burning of stubble. These systems reduce the levels of organic matter and biological activity in soil

Using Physical, Chemical And Biological Indicators To Assess Water Quality On The Ouachita National Forest Utilizing Basin Area Stream Survey Methods, J. Alan Clingenpeel, Betty G. Cochran

Journal of the Arkansas Academy of Science

The Ouachita National Forest (ONF) has developed a series of Best Management Practices (BMP's) designed to protect water quality and associated beneficial uses (fisheries, municipal water supplies, etc.). A monitoring program is necessary to document the effectiveness of that protection. The Basin Area Stream Survey (BASS) methodology provides a monitoring link from BMP's to the aquatic ecosystems. The goal of BASS is to identify the physical, chemical and biological characteristics of a stream in a format that will allow comparisons with other streams, and indicate when a stream is being impacted. Six index streams within two ecoregions were selected and …

A Study Of The Summer Steelhead, Oncorhynchus Mykiss In Several Intermittent Tributaries Of The Satus Creek Basin, Washington, Joel Denney Hubble

All Master's Theses

The summer steelhead, Oncorhynchus mykiss population was studied in three intermittent tributaries in the Satus Creek Basin. There was a strong tendency for post emergent fry, resulting from redds located in intermittent reaches to move downstream. However, survival to perennial flow conditions was very low. Steelhead production in Dry Creek appears to be lower than in Logy Creek, because of elevated water temperatures and minimal spring and summer stream flow.

Towards The Development Of A Kantian Environmental Ethic, Sally Nelson Wiedmann

Dissertations and Theses @ UNI

This thesis is a response to Aldo Leopold's 1949 call for a new, wholistic environmental ethic. Leopold's call stemmed from his concern over the increasing degradation of the environment as a result of a utilitarian approach which judges nature as good only insofar as it is good for human economic and recreational benefit. This thesis is aimed at the development of a wholistic, non-utilitarian environmental ethic grounded in the philosophy. of Immanuel Kant. The thesis begins with a brief review of the utilitarian environmental ethic which Leopold opposed and some of the consequences it has wrought in the natural world. …

Characterization Of Aspartic Proteinases From The Gut Of The Tick, Rhipicephalus Appendiculatus Neuman, Waha R.M. Vundla, Michel Brossard, David J. Pearson, Victor L. Labongo

All Peer-Reviewed Publications

Two proteinases designated 1 and 2, purified from the gut of partially engorged female, Rhipicephalus appendiculatus have been characterized. Both proteinases hydrolysed denatured haemoglobin (Hb) at acid pH, with Michaelis constants (KM) of 1.19 g/100 ml (proteinase 1) and 0.71 g/100 ml (proteinase 2). Pepstatin competitively inhibited both proteinases, with a K1 of 1.7 nM (proteinase 2). Both proteinases were also inhibited by 1 mM phenylmethylsulphonyl fluoride (PMSF). The pH optimum for proteinase 1 was 3.0, with a smaller but distinct second peak at pH 4.6. For proteinase 2, peak activity was at pH 2.6 with a second smaller peak …

Measurement Of The Removal Of Selected Vocs From A Municipal Treatment Plant, Hong Yu

Theses

Industrial wastewater contains a variety of volatile chemical constituents. The large majority of the volatiles are organics. Many of these volatile or¬ganic compounds (VOCs) end up in the effluent to wastewater treatment plants. It is necessary to estimate the emission of the VOCs from sewerage plants in order to study the fate of these volatile organic compounds.

This study focuses on the estimation and comparison of the emission of 28 volatile organic compounds from the water and air in four operation units of Linden Roselle Sewerage Authority (LRSA) wastewater treatment plant. The removal rates of these target compounds have been …

The Effects Of Oxygen Tension On Nitrate Reduction By Pseudomonas Isolate, Hao-Jan Hsing

Theses

It is a generally accepted concept that nitrate reduction only occurs under anaerobic conditions. Oxygen inhibits denitrification. However many studies of nitrate reduction under low oxygen tension have shown what has been called aerobic denitrification. This project examines the process of aerobic denitrification.

Oxgyen affects cell growth and the amount of nitrate utilized. When oxygen is absent, the cell growth rate is lower and nitrate utlization is higher then when oxygen is present.

Nitrate is reduced to nirite under anaerobic conditions. Nitrite accumulation did not continue increase. But increased then decreased producing a "Z" shaped graph when plotted.

Environmental Radiocesium In Subarctic And Arctic Alaska Following Chernobyl, M. Baskaran, J. J. Kelley, A. S. Naidu, D. F. Holleman

Environmental Science and Geology Faculty Research Publications

Radiocesium (¹³⁴ Cs and ¹³⁷ Cs) concentrations were measured in soil, plant and wildlife samples from subarctic to arctic Alaska. Concentrations of ¹³⁷ Cs ranged from below detectable or low levels in whale and fish samples to as high as 242 Bq/kg in lichen. For all potential human food items, the radiocesium concentrations measured in this study were below accepted permissible levels for human consumption. Chernobyl-derived radiocesium concentrations ranged from below detectable or low levels in all arctic samples (soil, sediment, lichen, whale, fish and caribou) to 32 Bq/kg in subarctic moss. Therefore the distribution and subsequent deposition of Chernobyl-derived …

Preliminary Epidemiological Interpretation Of The Intrinsic And Extrinsic Factors Contributing To The Coverage And Participation Rates Of The Vaccination Program In Arssi, Ethiopia, Muchie Kidanu

Electronic Theses and Dissertations

Many immunization programs in developing countries arr now undergoing a period of rapid utilization. Innovative strategies, such as immunization holidays, are being tried. Political commitment and enthusiasm are high. There is a strong desire by health professionals to protect the lives of many children from the untimely death and/or disability resulting from infectious diseases preventable by vaccination.

Evaluation of an immunization program can benefit other elements of the health system, particularly those that are not amenable to objective evaluation as immunization. In this case, immunization can serve as an indicator of the overall performance of the health system. The problems …
