The Anomalous Mössbauer Fraction Of Ferritin And Polysaccharide Iron Complex (Pic), M. E. Y. Mohie-Eldin, Richard B. Frankel, L. Gunther, G. C. Papaefthymiou Dec 1995

The Anomalous Mössbauer Fraction Of Ferritin And Polysaccharide Iron Complex (Pic), M. E. Y. Mohie-Eldin, Richard B. Frankel, L. Gunther, G. C. Papaefthymiou

Physics

Mössbauer studies of the ubiquitous protein molecule ferritin and its synthetic "biomimic" polysaccharide iron complex (PIC) exhibit an anomaly in the Mössbauer spectrum wherein the recoil free fraction f-factor has a sharp drop with respect to temperature as the temperature rises above 30 K for mammalian ferritin and 60 K for PIC. The anomaly coincides with the disappearance of hyperfine splitting, which is due to superparamagnetic relaxation above the blocking temperature. Different absorbers were used to experimentally investigate the effect of absorber thickness on the Mössbauer spectrum. The anomaly persists for thin absorbers. Also, spectra treated with FFT procedures …


Regulation Of The Expression Of Lipogenic Enzymes By Insulin-Mimetics, Juiyu Wu Dec 1995

Regulation Of The Expression Of Lipogenic Enzymes By Insulin-Mimetics, Juiyu Wu

Masters Theses

Many researchers have shown that selenate (SeO42-) and vanadate (VO42-) have insulin-mimetic effects in certain biological processes. These mimetic effects include increasing glucose transport, regulating glycolytic enzymes, normalizing plasma glucose levels and activities of insulin regulated enzymes in diabetic rats. To clarify the functions and roles of these insulin-mimetics in different insulin-regulated metabolic pathways, the expression of the genes for glucose-6-phosphate dehydrogenase (G6PDH) and fatty acid synthase (FAS) were investigated. G6PDH is a key enzyme in the pentose phosphate pathway and is also involved in lipogenic metabolism by providing 55-70% of the NADPH utilization …


Effects Of Insulin And Insulin Mimetics On Antioxidant Enzyme Levels: In Vivo And In Vitro, Shikha Varma Dec 1995

Effects Of Insulin And Insulin Mimetics On Antioxidant Enzyme Levels: In Vivo And In Vitro, Shikha Varma

Masters Theses

Tissue antioxidation status is considered to be an important factor for elucidating the etiology of diabetes and its physiological complications. This study was aimed to determine the in vivo antioxidant enzyme levels in the altered antioxidant status of diabetic rat liver with the treatment of two potent insulin mimetics, vanadium and selenate. The direct effects of vanadate, selenate, and zinc (another insulin mimetic) on the antioxidant enzyme levels in primary rat hepatocytes in culture was also determined. Levels of superoxide dismutase (SOD), catalase (CAT) and gluthahione peroxidase (GPX) were determined in both model systems.

In the vivo model, insulin treatment …


The Relationship Between Environmental Attitudes And Environmental Behaviors Among Air Force Members, Daniel T. Holt Dec 1995

The Relationship Between Environmental Attitudes And Environmental Behaviors Among Air Force Members, Daniel T. Holt

Theses and Dissertations

A questionnaire was distributed to nearly 2,000 randomly selected active duty Air Force members assigned to locations throughout the continental United States. The survey was designed to determine the extent to which Air Force members expressed support for environmental issues. In addition, the survey measured how frequently Air Force members engaged in specific behaviors that were deemed environmentally protective. Although the Air Force members expressed relatively strong support for environmental issues, they only occasionally engaged in activities that contribute to the preservation or protection of the environment. Correlation analysis revealed that the pro-environmental attitudes were positively linked to the environmentally …

Soil Acidity. A Reference Manual., Linda Leonard, Mike D. Bolland

Natural resources published reports

This publication is intended as a guide for consultants, development officers and field representatives for the extension of soil acidity in Western Australia.

Most Western Australian soils are naturally acidic. Acid peaty sands in the high rainfall area of the South West are the only W.A. soils in which natural acidity has been treated routinely before productive agriculture was introduced. There are approximately 100, 000 hectares of acid, peaty sands scattered through coastal districts between Pemberton and Rocky Gully districts.

Sabbatical Leave Proposal, Brenda Marshall

Sabbaticals

I'd like to learn "Mathematica." "Mathematica" is probably the most~ powerful mathematics software available. It was developed and continues to be upgraded at Wolfram Research in Champaign. The U. of I. as well as many colleges and universities across the nation teach some sections of their calculus courses with "Mathematica." Also, several of the high schools in our district have students enrolled in "Calculus with Mathematica" through a distance learning program at the U. of I.


Extirpation Of A Recently Established Feral Pig Population In Kansas, Chad D. Richardson, Philip S. Gipson, David P. Jones, James C. Luchsinger Nov 1995

Extirpation Of A Recently Established Feral Pig Population In Kansas, Chad D. Richardson, Philip S. Gipson, David P. Jones, James C. Luchsinger

Wildlife Damage Management Conference

Most feral pigs (Sus scrofa) are descendants of domestic swine that have gone wild and their reproduction is uncontrolled by man. A few populations may be descendants of European wild boar or crosses between wild boar and domestic swine. Disease control officials report that 23 states have established populations of feral pigs and the total feral pig population in the United States is probably in excess of 2 million animals. A population of feral pigs was documented in the fall of 1993 on the Fort Riley Military Installation in northeastern Kansas. Biologists from the Fort Riley Natural Resources …


The Professional Evolution Of Wildlife Damage Management, James E. Miller Nov 1995

The Professional Evolution Of Wildlife Damage Management, James E. Miller

Wildlife Damage Management Conference

The term -- wildlife damage management, in lieu of animal damage control, vertebrate pest control, or nuisance animal control -- has become the currently recognized term for an area of wildlife management that a growing number of professionals spend a significant part of their time and/or career working in. The acceptance of this terminology is, however, a part of the continuing evolution of the profession and not simply a name change for political correctness. Admittedly, my purpose is not to validate or beg acceptance of this terminology. Rather, what I hope to do is to justify the underlying premise of …


Efficacy Of Shooting Permits For Deer Damage Abatement In Wisconsin, Rick R. Horton, Scott R. Craven Nov 1995

Efficacy Of Shooting Permits For Deer Damage Abatement In Wisconsin, Rick R. Horton, Scott R. Craven

Wildlife Damage Management Conference

The efficacy of out-of-season shooting permits for deer damage abatement in Wisconsin has not been critically evaluated. We used deer damage shooting permits to remove 21 antlerless deer (Odocoileus virginianus) from 7 heavily damaged alfalfa fields to evaluate subsequent impact on crop damage. Volunteer shooters, using permits issued to the landowners, hunted a minimum of 3 nights/week throughout the growth of the third alfalfa crop (Aug. 1 - late Sept.). We calculated the difference between the assessed damage to the second crop (untreated) and the third crop (treated) on treatment and control farms. We found no significant difference …

Pesticide Use By The Federal/Cooperative Animal Damage Control (Adc) Program, 1988-1991, Guy Connolly

Eastern Wildlife Damage Management Conference: 7th (1995)

ADC personnel use many wildlife damage control methods including pesticide products. This paper presents a national overview of the kinds and amounts of chemical pesticides used by ADC in direct control activities during Fiscal Years (FY) 1988-1991. The pesticides used by ADC included aluminum phosphide, 4-aminopyridine, bone tar oil, brodifacoum, carbon, alpha-chloralose, cholecalciferol, DRC-1339, fenthion, glyphosate, immobilizing & euthanizing drugs, mineral oil, PA-14, phosphorus, polybutene, sodium cyanide, sodium fluoroacetate, sodium nitrate, strychnine, sulfur, and zinc phosphide. This summary shows that ADC personnel used remarkably small amounts of chemicals during FY 19881991. Overall amounts of pesticides used by ADC have changed …


Survey Of Black Bear Depredation In Agriculture In Massachusetts, Sandra A. Jonker, James A. Parkhurst Nov 1995

Survey Of Black Bear Depredation In Agriculture In Massachusetts, Sandra A. Jonker, James A. Parkhurst

Eastern Wildlife Damage Management Conference: 7th (1995)

Black bear (Ursus americanus) depredation in agriculture has become an increasing concern in Massachusetts. Complaints from apiarists, corn growers, and livestock producers have increased 167% during the period 1980 to 1990, but whether this increase truly represents more depredation, response of bears to other factors, or simply better reporting/record keeping has not been determined. The bear population in Massachusetts from 1984 to 1989 increased 50°/a to approximately 700-750 animals statewide. Subsequent estimates (1995) have placed the bear population around 1,200 animals. Concurrent encroachment of human development into prime bear habitat also increased contact between bears and humans. During …


Wildlife Damage Control In Kansas: Private Operators And Public Agencies, L. Andrew Madison, Philip S. Gipson Nov 1995

Wildlife Damage Control In Kansas: Private Operators And Public Agencies, L. Andrew Madison, Philip S. Gipson

Eastern Wildlife Damage Management Conference: 7th (1995)

The private industry in wildlife damage control is expanding into territory predominantly occupied by public agencies in the past. There is a potential for overlap and competition in services provided by the public and private sectors in Kansas. We examined wildlife damage control activity reports from the Cooperative Extension Service (CES), Kansas Department of Wildlife and Parks (IDWP), and private nuisance wildlife control operators (NWCO) to determine the most common species controlled by each and their overlap in services across Kansas. The CES predominantly controlled coyotes (Canis latrans). KDWP primarily controlled beavers (Castor canadensis), deer ( …


A Historical Perspective Of Catfish Production In The Southeast In Relation To Avian Predation, Donald F. Mott, Martin W. Brunson Nov 1995

A Historical Perspective Of Catfish Production In The Southeast In Relation To Avian Predation, Donald F. Mott, Martin W. Brunson

Wildlife Damage Management Conference

Production of aquaculture species, especially catfish (Ictalurus punctatus) in the Mississippi Delta, is a relatively new and expanding industry. Catfish production represents the largest dollar value of the aquaculture industry, accounting for approximately 50% of the entire industry. Mississippi is responsible for 82% of the total U.S. catfish production. Fish-eating bird populations have capitalized on this new food source. Double-crested cormorants (Phalacrocorax auritus), great blue herons (Ardea herodias), and great egrets (Casmerodius albus) are the primary predators on catfish. Cormorant caused losses in excess of $2 million per year have been reported in …

Relationships Between Wild Turkeys And Raccoons In Central Mississippi, Charles D. Lovell, Darren A. Miller, George A. Hurst, Bruce D. Leopold Nov 1995

Relationships Between Wild Turkeys And Raccoons In Central Mississippi, Charles D. Lovell, Darren A. Miller, George A. Hurst, Bruce D. Leopold

Wildlife Damage Management Conference

Reduced trapping and hunting of predators has led to concerns that increased predator densities may affect game species populations. Therefore, we investigated effects of predation on the wild turkey population on Tallahala Wildlife Management Area (TWMA), Mississippi, from 1984-94. We also determined trends in raccoon trapping and hunter harvest in Mississippi. Predation of nests (eggs), nesting hens, and poults caused a population decline on TWMA. Most (88%) nest failures were caused by predation from 1984-94; raccoons were the dominant predator. Declining raccoon hunter harvest from 1980-94 was correlated with declining hunter effort. Trapping license sales and trapping harvest also declined. …


From Deer Problem To People Solution: A Case Study From Montgomery County, Maryland, Jonathan S. Kays, Douglas Tregoning Nov 1995

From Deer Problem To People Solution: A Case Study From Montgomery County, Maryland, Jonathan S. Kays, Douglas Tregoning

Wildlife Damage Management Conference

Montgomery County, Maryland, a 495 square-mile area adjacent to Washington, D.C., is a rapidly developing, highly educated suburban community with one of the highest per capita incomes in the nation. There is increasing concern for the growth and impact of white-tailed deer (Odocoileus virginianus) populations by agricultural interests, resource professionals and residential landowners. The Montgomery County Council assembled a task force of stakeholders to examine relevant information and propose deer management options. The task force report provided detailed information on the county deer situation, 11 management alternatives, and 9 final recommendations. The county parks administrator appointed a staff …


Evaluation Of The Yard Gard Ultrasonic Yard Protector For Repelling White-Tailed Deer, Paul D. Curtis, Christopher Fitzgerald, Milo E. Richmond Nov 1995

Evaluation Of The Yard Gard Ultrasonic Yard Protector For Repelling White-Tailed Deer, Paul D. Curtis, Christopher Fitzgerald, Milo E. Richmond

Wildlife Damage Management Conference

Ultrasonic devices are marketed for pest control because some manufacturers believe they possess properties aversive to animals. However, there is little evidence that ultrasound is more aversive to animals than is audible sound. In this study, we examined the efficacy of the Yard Gard ultrasonic device for deterring deer (Odocoileus virginianus) from feeding on apples. Four deer feeding stations were established at private residential properties with a history of deer damage to ornamental plants, so that control (A1 and B1) and experimental (A2 and B2) stations existed at each site. Apples were placed at each feeding station and …


Ecology And Control Of Wildlife Damage To Electric Substations, Glenn R. Dudderar, Scott R. Winterstein, Wendy H. Sangster Nov 1995

Ecology And Control Of Wildlife Damage To Electric Substations, Glenn R. Dudderar, Scott R. Winterstein, Wendy H. Sangster

Wildlife Damage Management Conference

This study addresses several aspects of the ecology and control of wildlife damage to electric substations because the amount of existing research is not sufficient to make informed decisions about how best to minimize that damage. Records of 121 incidents of animal-caused faults showed that 78% of the faults were caused by squirrels and raccoons and an average of 2,511 customers lost service during the outage caused by such a fault. Animal damage control measures were evaluated by observing challenges to control measures by raccoons and squirrels at a substation. The control measures were breached twice because they had not …


American White Pelicans: The Latest Avian Problem For Catfish Producers, D. Tommy King Nov 1995

American White Pelicans: The Latest Avian Problem For Catfish Producers, D. Tommy King

Wildlife Damage Management Conference

Animal Damage Control offices in Arkansas, Louisiana, and Mississippi began receiving complaints concerning American white pelicans (Pelecanus erythrorhynchos) foraging in commercial channel catfish (Ictalurus punctatus) ponds in 1990. Because of the relatively shallow pond depth and high fish stocking rates used by most producers, commercial catfish ponds provide a near perfect foraging environment for American white pelicans. Since 1993, pelicans seem to have become more persistent in their foraging efforts and therefore, more difficult to disperse from catfish farms. Damage abatement recommendations have consisted of harassment measures similar to those used for other piscivorous birds, issuance of …


Black Bear Damage In The Mississippi Alluvial Valley, Thomas H. White Jr., Catherine C. Shropshire, Mike Staten Nov 1995

Black Bear Damage In The Mississippi Alluvial Valley, Thomas H. White Jr., Catherine C. Shropshire, Mike Staten

Wildlife Damage Management Conference

We surveyed 62 hunting clubs in the batture of the Mississippi River in Arkansas and Mississippi to determine the extent and severity of black bear (Ursus americanus) damage. Bear damage was more prevalent in Arkansas (70.6%) than in Mississippi (11.8%). Damage to deer stands was most common (43.8%), followed by damage to buildings (22.9%), getting in garbage (12.5%) and damage to wildlife food plots (10.4%). Cost estimates of bear damage averaged approximately $40 per incident over the past 5 years. Most (90.9%) clubs rated bear damage as either a slight nuisance or not important at this time, and …

Apple Production, Vole Control, And Wild Turkeys: Finding A Balance In Vermont, Richard B. Chipman, Dennis Slate, Abigal J. Duke, Lorraine Berkett, Douglas Blodgett Nov 1995

Apple Production, Vole Control, And Wild Turkeys: Finding A Balance In Vermont, Richard B. Chipman, Dennis Slate, Abigal J. Duke, Lorraine Berkett, Douglas Blodgett

Wildlife Damage Management Conference

Meadow voles (Microtus pennsylvanicus) and pine voles (Microtus pinetorum) cause extensive damage to apple trees by gnawing and girdling trunk and root systems. In 1991, approximately 70% of Vermont's 90 commercial apple producers were using zinc phosphide (ZP) treated cracked corn to manage vole damage. From November 1991 through January 1992, 36 confirmed wild turkey (Meleagris gallopavo) deaths were attributed to the broadcast application of ZP treated cracked com in Vermont orchards. As a result of public concern regarding impacts to nontarget wild turkeys, a working group was formed with representation of various state …


Ecosystem Management And Wildlife Management: Compatible Or Conflicting?, David C. Guynn Jr., Greg K. Yarrow Nov 1995

Ecosystem Management And Wildlife Management: Compatible Or Conflicting?, David C. Guynn Jr., Greg K. Yarrow

Wildlife Damage Management Conference

Examples of wildlife-human conflicts include deer-automobile collisions, disease transmission concerns, and damage to various commodities (e.g. agricultural crops, timber production). The extent of these problems is increasing at a time when American's attitudes are shifting emphasis from commodity production to concern for the environment. Ecosystem management has been proposed as a strategy to balance concerns for commodity production and the environment. Ecosystem management, unlike traditional natural resource management, will require management over large areas for long periods of time. This new philosophy of land management requires that the natural resource base be viewed in its entirety, and not as separate …


Black Bear Damage Management In Washington State, Georg J. Ziegltrum, Dale L. Nolte Nov 1995

Black Bear Damage Management In Washington State, Georg J. Ziegltrum, Dale L. Nolte

Wildlife Damage Management Conference

Black bears (Ursus americanus) foraging on trees can be extremely detrimental to the health and economic value of a timber stand. A supplemental feeding program to reduce bear damage is coordinated by the Washington Forest Protection Association's Animal Damage Control Program (ADCP). A brief overview of the ADCP is provided along with a description of bear damage and the supplemental feeding program. Success of the feeding program is demonstrated by an increasing participation and its general acceptance by the public. Timber producers placed over 400 thousand pounds of pellets in 700 feeding stations this past year.

Blackbirds And Starling Killed At Winter Roosts From Pa-14 Applications, 1974-1992: Implications For Regional Population Management, Richard A. Dolbeer, Donald F. Mott, Jerrold L. Belant

Wildlife Damage Management Conference

The surfactant PA-14, registered with the U.S. Environmental Protection Agency (EPA) in 1973 by the federal Animal Damage Control (ADC) program, was used for 19 years (1974-1992) for lethal control of roosting blackbirds (Icterinae) and European starlings (Sturnus vulgaris) in the United States. In 1992, the ADC program withdrew the registration of PA-14 because of costs required to provide additional EPA-requested data. There were 83 roosts encompassing 178 ha treated with 33,300 L of PA-14 from 1974-1992. An estimated 38.2 million birds (48% common grackles [Ouiscalus quiscula], 30% European starlings, 13% red-winged blackbirds [ …

Mississippi's Beaver Control Assistance Program, 1989-1994, Philip Mastrangelo

Wildlife Damage Management Conference

Responding to landowner requests, the 1989 Mississippi Legislature created the Beaver Control Advisory Board and mandated it to develop a program which would ensure the control of beaver damage throughout Mississippi. The Advisory Board is comprised of the administrative heads of five state agencies: the Department of Wildlife, Fisheries, and Parks (chairperson), the Department of Transportation, the Cooperative Extension Service, the Forestry Commission, and the Department of Agriculture and Commerce. In cooperation with the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Animal Damage Control (ADC) program, the Advisory Board developed the Beaver Control Assistance Program (BCAP). BCAP …


Rodent Damage Control In No-Till Corn And Soybean Production, Ron Hines Nov 1995

Rodent Damage Control In No-Till Corn And Soybean Production, Ron Hines

Wildlife Damage Management Conference

In recent years the primary cause of reduced plant stands in no-till crops planted into heavy residue has been small eared rodents called voles (Microtus spp.). Past research has indicated that severe stand reductions (80 to 100 percent) can occur if vole populations in the field exceed 75 per hectare (30 per acre) at planting time. This vole population should be considered intense. If field scouting about 30 days prior to planting reveals at least 12 active vole colonies per hectare (five per acre) an intense population can develop, and damage control measures should be planned. Of all …

Assessment Of Gnawing Behavior Of Three Rodent Species On Automatic Speed Control Mechanism Diaphragms From Gm Automobiles, Glenn R. Dudderar, Ren-Rong Hou, Scott R. Winterstein

Wildlife Damage Management Conference

General Motors and the A C. Rochester Company, a subsidiary of General Motors (GM), has found that the rubber diaphragms on automatic speed control mechanisms (servos) were gnawed by unknown rodents. House mice (Mus musculus), Peromyscus spp., and eastern chipmunks (Tamias striatus) were used to test gnawing behavior on 4 kinds of diaphragms. Diaphragms with or without a rodent proof cure formula, which are used by GM, did not influence the gnawing of all test rodent species. Diaphragms with a lubricant (Paricin) were more attractive to gnawing by house mice than diaphragms without a lubricant. …
