The Isolation And Characterization Of A Novel Iron Protein From Desulfovibrio Gigas, Alan Kay Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The isolation, purification, and partial characterization of a novel iron-containing protein from the sulfate-reducing anaerobic bacterium, Desulfovibrio gigas, is described. The highly insoluble protein was isolated from the cell debris following osmotic shock of the bacteria. The insoluble fraction consistently contained about 90% of the cell-associated iron. This protein was treated with acid, chelating agents, detergents and proteases in order to study their effect on the iron solubility. The results of elemental analysis of a crude protein preparation were 5.3% iron, 2.9% sulfur and 11 .9% nitrogen. An independent colorimetric iron analysis showed 6.4% iron. The iron could be …

An Anatomical Investigation Of Roots From C3 And C4 Grasses With Emphasis On Phloem Organization, Eric A. Rechel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Root phloem structure was researched in taxonomically related C3 and C4 grass species. The functional aspect of phloem unloading in the root was then discussed in terms of this observed structure. In Triticum aestivum L. (C3) each phloem bundle consists of one protophloem sieve-tube element, two companion cells, and one metaphloem sieve-tube element. Protophloem sieve-tube elements and companion cells are contiguous with the pericycle. Centripetally the companion cells are in contact with the metaphloem sieve-tube element. All are separated from tracheary elements by stelar parenchyma. Eighty-four percent of the lateral connections observed in protophoem sieve-tube elements are associated with the …

Western White Pine: The Effect Of Clone And Cone Color On Attacks By The Mountain Pine Cone Beetle, Michael J. Jenkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between clone and cone color in western white pine, Pinus monticola Douglas, to attack by the mountain pine cone beetle, Conophthorus monticolae Hopkins, was studied in the Sandpoint Seed Orchard, Idaho. A positive relationship was shown to exist during a 5 year field evaluation. Cone beetles were found to prefer dark colored cones and to attack certain clones at a higher rate than others.

Laboratory dissections did not indicate that cone color affected oviposition, brood development or brood mortality.

Olfactometer experiments demonstrated that olfactory stimuli are involved in the cone beetle attack sequence. Visual cues relating to cone …

The plant is known to induce poisoning in laboratory animals, but there are no precise references on doses to be utilized and of appropriate routes of dosing. Oral …

The Influence Of Winter Social Behavior On The Habitat Selection And Reproductive Success Of The Black-Billed Magpie, Kerry P. Reese

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the influence of winter social behavior, particularly dominance relationships, on the subsequent nesting habitat selection and reproductive success of Black-billed Magpies (Pica pica hudsonia) on 2 areas in northern Utah. Hierarchical cluster analysis ordinated the habitats available to breeding birds and Chi-square and Bonferoni-z statistics were used to determine those habitat types the magpies seemed to prefer. Social status was determined by observing color-banded birds engaged in agonistic encounters at winter bait stations. Social dominance was evaluated by % dyads won, not by total % victories. Relationships between winter social status of magpies and their …

Comparison Of Fishery Policies And Management Techniques Of The United States And Iceland, Ted I. Lillestolen

Marine Affairs Theses and Major Papers

In 1976, the United States enacted the Fishery Conservation and Management Act (FCMA), presently referred to as the Magnuson Fishery conservation and Management Act (MFCMA). The legislation is a complex and detailed document establishing for the first time a national fishery policy. The Act also created an organizational structure designed to implement this new policy. Since the Act's implementation, there has been a great deal of controversy, especially generated by the commercial fishermen. This paper focuses on Iceland, primarily because of its great economic dependency on its fisheries resources, unlike the United States.

Innovations In Hay Harvesting And Storing, V. L. Lectenberg, D. A. Holt

Kentucky Alfalfa and Stored Forage Conference

Haymaking in the humid parts of the U.S. is the most risky operation that farmers engage in. Standing hay is extremely high in moisture and must be dried to at least 25% moisture less before it can be stored without spoilage. Most farmers rely on natural field drying processes to cure their hay. Natural drying is often slowed by high relative humidity. Rainfall frequently occurs before the hay has dried which further slows the drying process and can result in serious nutrient and yield losses. Haymaking is also a labor-intensive farming operation and, until recently, involved a large amount of …

Structure Of Maltoheptaose By Difference Fourier Methods And A Model For Glycogen, E. Goldsmith, S. Sprang, R. Fletterick

Biological Sciences Faculty Publications

The structure of the glucose heptamer, maltoheptaose, has been determined by difference Fourier analysis at 0.25 nm resolution through its binding to phosphorylase a. It is a left-handed helical structure, with 6.5 glucose residues per turn and a rise per residue of 2.4 Å. The molecule shows short-range order when no protein is present to stabilize its conformation in solution. With one exception, the individual torsion angles between sugar residues vary over a narrow range and preserve a good O₍₂₎O_(3′) hydrogen bond. The length of an individual chain for glycogen can be extrapolated from the maltoheptaose data …

Variables Affecting Impregnation During Kraft Pulping, William J. Corriveau

Paper Engineering Senior Theses

Introduction

The purpose of this report was twofold. First, a pulping aid was evaluated for its effects on pulp properties. Then, the pulping aid was used in conjunction with a reduction in the times to temperature for several cooks, to see if the pulping aid could be used to reduce the total cooking time for kraft cooks.

To gain some background as to how the pulping aid might affect the cook, variables affecting impregnation are presented and discussed.

Anaerobic Degradation Of Pulp And Paper Industry Landfill Leachate In Soil, Susie K. Leclear

Paper Engineering Senior Theses

The objective of this project is to determine if organics in pulp and paper industry leachates can undergo anaerobic degradation in soil. If the leachate does degrade, it could reduce the potential for groundwater pollution. Attenuation, the decrease in the concentration of contaminants, can be affected by different soil parameters like biological activity, particle size and pore spaces. Also, temperature can affect the rate of degradation.

Not only does this study want to show the presence of degradation, but also the effects of adsorption with different soils.

The results of pH, ORP, and COD tests show that degradation occurred at …

Sunset As An Orientational Cue For A Nocturnal Migrant, The White-Throated Sparrow (Zonotrichia Albicollis), James Pauly

Masters Theses & Specialist Projects

The possibility that nocturnal migrants use sunset as an orientational cue was explored in the White-throated Sparrow (Zonotrichia albicollis) between 1 April and 24 April, 1981. Orientation tests were run on the roof of the biology building at Western Kentucky University when birds were assumed to be in the proper physiological condition for migration. Birds exposed to only nighttime skies, birds isolated from all visual cues, and birds exposed to both daytime and nighttime skies did not exhibit the northward directional preference appropriate for the season tested. However, White-throated Sparrows exposed only to sunset and tested in the absence …

Interaction Of Specific Contaminants In Pulp And Paper Effluents/ Leachates With The Soil, Steven G. Ziolkowski

Paper Engineering Senior Theses

This thesis deals with the interaction of specific contaminants in pulp and paper effluents and how they leach into the soil. The mill included in my study applies its effluent to special irrigation fields on a daily basis. The mill produces some specialty paper which involves the use of heavy metals in its paper-making process and as a result some of the metals are applied on the irrigation field. By taking soil samples from the irrigation fields and analyzing them for heavy metals, I hope to come up with some conclusions for the behavior of vertical migration of heavy metals …

Stand Risk Rating For The Southern Pine Beetle: Integrating Pest Management With Forest Management, Gordon L. Autry

Faculty Publications

Stand risk rating for the southern pine beetle.

Dendroctonus frontalis Zimm., is a first step toward dealing with a serious but sporadic insect problem. Two approaches, one utilizing readily available resource data, the other employing data obtained from aerial photographs, illustrate application of current knowledge to meet the protection needs of resource management-the primary role of integrated pest management. During a 36-month period in Louisiana, high-risk stands accounted for 13.4 infestations per 1,000 acres, four times the rate of low-risk stands; in Texas high-risk stands accounted for 9 .9 infestations per 1 ,000 acres during 1973-1978, almost five times the …

Differences Associated With Mating Type Alleles In Myxomycetes, Robert M. Queen

Retrospective Theses and Dissertations

Differences associated with the mating type alleles of Didymium iridis and Physarum polycephalum were examined with fluorescent antibody and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Heteroabsorption of each anti-myxamoebal serum followed by testing serum activity using immunofluorescence showed there is no strain-specific activity in any of the anti-myxamoebal sera, but the sera was shown, to be genera specific. Intergeneric differences and similarities were shown in the electrophoretic patterns of the myxamoebal protein extracts from P. polycephalum, D. iridis, and Dictyostelium discoideum when compared. Intraspecific differences were noted in D. iridis.

Evidence For The Horizontal Acquisition Of Murine Akr Virogenes By Recent Horizontal Infection Of The Germ Line, Stephen J. O'Brien, Janet L. Moore, Malcolm A. Martin, James E. Womack

Biology Faculty Articles

Several recent reports have established the biological and molecular genetic similarity between the endogenous AKV virus of strain AKR, and an N-ecotropic endogenous virus found in the genome of feral Japanese mice, Mus musculus molossinus. The similarities are so striking as to suggest a common origin of these viruses, which are present in some, but not all, inbred mouse strains. The virogenes of AKR mice may have been acquired by either: (a) common descent of AKR (and other AKV⁺ strains) from a common ancestor of AKR and molossinus animals, or (b) horizontal germ line infection of the AKR …

Glycosaminoglycans Of Normal And Diabetic Human Plasma, Gloria Badiner

Masters Theses

Diabetic complications in nnn-insulin dependent tissues have led < researchers to investigate causitive parameters at the biochemical level. The purpose of this project was to measure glycosaminoglycans in diabetic and normal human plasma and to investigate any changes in glycosaminoglycan content for possible roles in diabetic complications.

Glycosaminoglycan content was measured by three methods; the alcian blue assay, protein-bound hexosamine, and total glycosaminoglycan isolate methods. Results show IDDM plasma to have significantly increased levels of glycosaminoglycans as assayed by the alcian blue test and protein-bound hexosamine. The total glycosaminoglycan isolate method did not correlate with either of the two other methods. No difference was demonstrated between normal and NIDDM plasma glycosamino glycan content.

The protein-bound hexosamine and the alcian blue assays correlate with age and type of diabetes. No differences between the sexes were demonstrated. Of particular interest are …

A Comparison Of Recruitment Strategies Among Brachyuran Crustacean Megalopae Of The York River, Lower Chesapeake Bay And Adjacent Shelf Waters, David Franklin Johnson

OES Theses and Dissertations

Twenty-one stations forming a transect of the Pamunkey River, York River, lower Chesapeake Bay and adjacent coastal waters were sampled from July through September 1980. The megalopa stages of 11 brachyuran species were sampled. Vertical and horizontal distributions are described for each species in relation to salinity and water column stratification. The megalopae are assigned to three apparent recruitment strategies: retained estuarine, expelled estuarine and retained coastal megalopae. the megalopa stages of estuarine adults, such as Hexapanopeus angustifrons, Neopanope sayi, Panopeus herbstii and Pinnotheres ostreum, are retained in estuarine epibenthic waters, while Rhithropanopeus harrisii are retained in slightly shallower …

Food Habits And Ecology Of Beavers In Southeastern Virginia, John Lennox Echternach Jr.
