Control Of Beaver Damage, James E. Miller

Wildlife Damage Management Conference

Beaver activity often conflicts with human's interests when damage occurs. It also has significant impact on the ecology of an area modified extensively by constant flooding. This often makes control of these animals somewhat different than for some other vertebrate species which cause serious damage. However, even though in biological terms beaver control may seem rather simple, in reality other factors including social, economic, and political pressures often dictate our actions more than dealing with the biological parameters of the species.

Press Section White Water Reuse, James Michael Tacey

Paper Engineering Senior Theses

In today's economy, more and more papermills are becoming increasingly concerned with white water reuse. White water is most frequently used for fan pump dilution, and consistency regulation. This white water usually comes strictly from the tray boxes of the paper machine. It was suggested that the white water from the press section could be reused. It was suggested to me by Dan Kaiser, of Ronningen-Petter, that this could be accomplished by using their Cyclospray filter. The testing run showed that the unit is very effective in removing the fibrous contaminants from the press section water. I found the unit …

Recombinant Immune Interferon Increases Immunoglobulin G Fc Receptors On Cultured Human Mononuclear Phagocytes, Paul M. Guyre, Peter M. Morganelli, Renee Miller

Dartmouth Scholarship

Although recent studies suggest that interferons can increase the number of IgG Fc receptor (FcR gamma) sites on mouse macrophages, direct assessment of similar effects on human mononuclear phagocytes is lacking. We therefore measured the specific binding of 125I- and fluorescein-labeled IgG1 to human monocytes and leukemic cell lines after culture in vitro with highly purified human interferons. We report that natural and recombinant human gamma-interferon causes a dramatic (nearly 10-fold) increase in the number of FcR gamma on normal human monocytes and on the human cell lines HL-60 and U-937. Alpha and beta-interferons cause a modest but significant increase …

The Effect Of Crowding On Growth Of The Cichlid Fish, Oreochromis Mossambicus, Bonnie A. Barrows

OES Theses and Dissertations

It has been reported that the Java tilapia, Oreochromis mossambicus, displays hypersensitivity to a substance it produces when biomass levels in a flow-through culture system exceed 20 g/1, resulting in reduced growth and high mortality. Experiments on the growth of this species in small tanks were conducted in order to determine whether O. mossambicus produces a growth-inhibiting compound under crowded conditions. This species was successfully maintained at biomass levels of 38 g/1 and 57 g/1 with a total mortality of only 4.5%.

The Java tilapia can grow rapidly in small aquaria, as indicated by the data taken during Experiment …

Experience With Biosynthetic Human Insulin In Diabetes, Davida F. Kruger, Fred W. Whitehouse, Dorothy M. Kahkonen, Jean O. Partamian, J. David Fachnie, José Goldman, David Leach

Henry Ford Hospital Medical Journal

Thirty diabetic patients new to insulin were entered in an open label prospective study of biosynthetic human insulin (BHI). All patients experienced symptomatic control of diabetes attributable to dietary and BHI insulin therapy. Detailed six-month evaluation data were reviewed in 19 patients. A significant drop in fasting plasma glucose and glycosylated hemoglobin was noted at two months, and a further modest decrease occurred at six months. E. coli polypeptide antibodies were unchanged from baseline at six months, indicating that no bacterial protein contamination of BHI occurred. Percent binding of serum antibodies to human insulin measured in 19 patients at baseline …

Effects Of Surface Application Of Dairy Manure On The Infiltration Rate And Quality Of Surface Runoff, Joseph L. Taraba, I. J. Ross, John D. Bottom, Bill J. Barfield

KWRRI Research Reports

Dairy manure was surface spread on 12 ft x 12 ft plots on an established fescue pasture in the summer and fall of 1981 and 1982. The soil was a Maury silt loam. A simulated rainfall was applied to plots to test the effects of nitrogen loading rate (75, 150, and 300 #N/acre) time delay between manure application and the simulated rainfall events (0, 3, 6, 24, 48, 96 hours and a 120 hour test repeated on 0 hr plot with 300 #N/acre), and type manure (semi-solid - 1981 and liquid - 1982) on the concentrations of pollutants in the …

The Effect Of The Endangered Species Act Of 1973, Robert Palmer Yankle Ii

Marine Affairs Theses and Major Papers

Scrimshaw, as an art form, had just recently risen a few notches above the state of obscurity. There are still millions of Americans who probably know nothing about it. Inextricably linked with the whaling industry for years, the scrimshaw industry has recently undergone a remarkable transition. When whaling ended in the United States, scrimshaw moved ashore and some people found out that there was a great deal of money to be made in the scrimshaw business. but with the passage of the Marine Mammals Protection Act in 1973, scrimshanders found themselves being tightly regulated by the Federal government. This paper …

Ammonia Volatilization From Fertilized Turfgrass Stands, W. A. Torello, David J. Wehner, A. J. Turgeon

Office of the Dean (CAFES) Scholarship

Nitrogen applied to turfgrass stands can be lost through leaching, denitrification, or ammonia (NH₃) volatilization. The purpose of this investigation was to evaluate the effects of N carrier and mode of application on NH₃ volatilization from a Kentucky bluegrass (Poa pratensis L.) turf growing on an acidic (pH 6.4) Flanagan silt loam (fine, montmorillonitic, mesic Aquic Argiudoll) soil. The NH₃, which volatilized after application of any of several sulfur-coated ureas (SCU), prilled urea, spray-applied solubilized urea, and two liquid N products was measured by passing the airstream from microecosystems, in which the treated turfs …

Using Videodisc Technology And The Index Of Nutritional Quality To Teach Dietary Guidance To Young Adults, Glenda Wigginton Edmunds

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A review of the literature indicated a need for nutrition education materials to be current with prevailing scientific knowledge, using advanced instructional technology. Individuals need help in applying nutrition principles to their dietary practices.

A nutrition education program utilizing the nutrient density concept and the dietary guidelines for use on videodisc with microcomputer interface was developed and evaluated. The evaluation of the program did not prove to be effective statistically but learners did show an interest in the program and had positive feedback in regard to the information presented and the technology used.

The Photoregulation Of Phenylpropanoid Metabolism And Amino Acid Accumulation In Triticum Aestivum (Var. Fremont), Daniel J. Guerra

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat (Triticum aestivum L.) grown in controlled environments with a 24-hour photoperiod was analyzed for phenylpropanoid and amino acid metabolites. Discrete spectral environments, including a metal halide, high-pressure sodium and low-pressure sodium lamps, provided both photosynthetically active radiation and phenylpropanoid inducing fluences of light. A greenhouse spectral environment supplemented with fluorescent lamps was also used to culture wheat. All four spectral environments were used to culture wheat to maturity separately. The activities of phenylalanine and tyrosine ammonia-lyase were photoinduced in wheat tissue obtained from plants grown in the metal halide, high-pressure sodium and greenhouse spectral environments. These enzyme activities are …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A Spiral Plater and a Microtiter system were used to isolate and evaluate cultures for a paired strain culture program. Bacteriophage and temperature sensitivity data of 43 Streptococcus cremoris strains were introduced into a computer cluster program to pair the least similar strains.

Selected pairs were challenged with phage. Resistant mutants were developed.

Characteristics of proteinase positive and proteinase negative variants were examined. Proteinase positive isolates produced more changes in pH, cell mass and more generations in milk than their counter-parts. Paired proteinase negative cultures produced more change in pH and cell mass and more generations in milk than single …

A Study Of The Action Of Bovine Cathepsin D On Intramuscular Connective Tissue, Elimosaria Elikalia Maeda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cathepsin D has been postulated to play a role in the tenderization of meat with ageing. Meat toughness has been related to connective tissue content and degree of myofibrillar shortening. This investigation was undertaken to determine the activity of cathepsin D on bovine intramuscular connective tissue.

Highly purified cathepsin D preparations from bovine spleen and bovine sternomandibularis muscle were obtained by ammonium sulfate fractionation followed by affinity chromatography on pepstatin coupled to controlled pore size alkyl amine glass beads. Maximum proteolytic activity using hemoglobin as substrate was obtained at pH 3.5 and 3.8 for bovine spleen and muscle cathepsin D, …

An Evaluation Of Various Methods Of Roasting Whole Turkeys From The Frozen State, Kim Merida-Klemmedson Teot

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Methods of roasting frozen turkeys were evaluated to determine the optimum final internal temperature (71,77, or 82°C), the best low oven temperature method (foil tent vs roasting bag at 93,107, 121, and 135°c), and the best overall method (foil tent-121 °c, foil tent-163°C, roasting bag-163°c, foil wrap-232°C). The lower the final internal temperature the juicier and more tender the bird however, the 77°c final internal temperature is recommended because at the 71°c internal temperature, the thigh joint was unacceptably pink. Among the low oven temperature methods, birds roasted at 121°c received the highest average sensory scores. Birds roasted by the …

Enzymic Milk Coagulation: Casein Micelle Aggregation And Curd Formation, Donald J. Mcmahon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Enzymic milk coagulation was monitored by measuring changes in curd firmness and apparent absorbance of undiluted milk. Detection of coagulation, visually or rheologically, occurred after the milk changes from a system of aggregating particles to an extended space network. This change was observed as a shoulder in apparent absorbance plots and coagulation time was defined as the critical point in the aggregation process analogously to non-linear condensation polymerization reactions. It corresponds to the inflexion point during the period when apparent absorbance was rapidly increasing and can be calculated by fitting curd firmness data to an exponential equation.

Development And Pathogenicity Of The False Root-Knot Nematode Nacobbus Aberrans And Its Relationship With Heterodera Schachtii And Meloidogyne Hapla On Sugarbeet, Renato Nunzio Inserra

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Duration of embryogenic development of a Nebraska population of Nacobbus aberrans at 15 and 25 C were 51 and 9-10 days respectively. The first juvenile (J1) molted in the egg and the nematode emerged as J2. Kochia and sugarbeet root leachates did not significantly affect the percent of cumulative egg hatch. Temperature significantly affected juvenile emergence (P= 0.05), as less than 1, 5, and 20% of the eggs hatched at 5, 10 and 15 C, respectively. More than 70% of the eggs hatched at 20 and 25 C. At 25 C, postembryogenic development from egg to egg was …

Belt Filter Press Optimization With The Use Of Drainage Measurement, Jeffrey E. Farnsworth

Paper Engineering Senior Theses

The objective of this project is to determine if paper machine freeness meters can be applied to belt filter presses, so as to control the dosage rate of the polymer addition. Currently polymer dosage rates are set for the high demand loads and therefore, more polymer is used than is needed at the low demand loads. With the cost and use of chemical polymers increasing, the application of a control means to regulate polymer dose as required, should provide substantial savings in conditioning costs.

This study wants to show that a specific resistance tester is sensitive enough to pick up …

Investigation Of The Substrate Binding Site Of Nad Glycohydrolase In Human Seminal Plasma, Sau C. Cheung

Chemistry & Biochemistry Theses & Dissertations

Nicotinamide adenine dinucleotide glycohydrolase (NADase) (E.C. 3.2.2.5) from human seminal plasma (HSP) was partially purified through a multistep purification procedure, including affinity chromatography on Amicon Red Matrex Gel A. The NADase activity was assayed by a fluorometric method with nicotinamide 1,N⁶ -ethenoadenine dinucleotide as the substrate. The enzymatic cleavage of etheno-NAD by NADase was accompanied by an eight-fold increase in fluorescence. This large increase in fluorescence provided a sensitive way to follow the rate of etheno-NAD hydrolysis.

NADase was found to be less specific for the purine moiety of NAD, since etheno-NAD was accepted as a substrate. The enzyme …

Current Concepts In Otitis Media, Michael M. Paparella

Henry Ford Hospital Medical Journal

Otitis media continues to be a common and disabling problem which has become, in recent years, a fertile area for research. Based on studies in animals and humans, otitis media is classified into four groups: acute purulent otitis media (POM), serous otitis media (SOM), and mucoid or secretory otitis media (MOM). Together, these are referred to as otitis media with effusion (OME). The types can overlap and evolve into another type to become chronic otitis media and mastoiditis, characterized by the presence of granulation tissue or cholesteatoma. The biochemistry, microbiology, and pathology as well as clinical features of the disease …

Vivisection And Misanthropy, George P. Cave

International Journal for the Study of Animal Problems

The author comments on several articles in the media that imply or state that antivivisectionists are misanthropes who like animals more than people. The author notes that one commentator mistakenly claims that Peter Singer, author of Animal Liberation, equates animals and people. Singer does not claim that animals and people should be treated identically. Instead, Singer argues that animals and people are entitled to equal consideration of their interests. Different treatments will be justified if there are relevant differences between animals and people.

Alternatives To Animal Experimentation, Steven M. Niemi

International Journal for the Study of Animal Problems

Alternatives to animal experimentation are highly touted today by animal welfare advocates. Their campaign for adopting alternatives has caused much discussion and debate within and outside the biomedical community. This paper aimed to examine the controversy and assess the more common alternatives, including the bacterial mutagenicity assay or Ames test, cell culture, and mathematical models for toxicity prediction. Chemical safety testing is the most promising of the fields for alternatives where laboratory animals are used, and incorporating alternatives with live-animal assays is increasing. However, due to the limitations of alternatives in use currently, there is still a considerable need for …

The Potential Role Of Local Ethical Committees In The Moderation Of Experiments On Animals In Britain, D. P. Britt

International Journal for the Study of Animal Problems

Scientists working with laboratory animals in Britain are made aware forcibly that a severe ethical dilemma surrounds using animals in experiments. Certain vociferous sections of the community press the issue on the general public's attention, and media sources tend to propagate views expressed by the most extreme parties while neglecting coverage of mature, rational opinions. It is, perhaps, no bad thing for the scientific community to be frequently reminded to take a responsible attitude to the use of animals. Still, recent overt, even illegal, activity on the part of extremist animal protectionist groups has encouraged a regrettable polarization of viewpoints, …

Protection Of Animals And Animal Experimentation: A Survey Of Scientific Experts, Norbert Lagoni, Joachim Fiebelkorn, Hans-Joachim Wormuth

Experimentation Collection

This article summarizes information from a survey of biomedical scientists, specifically pharmacologists and toxicologists, on the use of laboratory animals and the potential for replacing their use with alternative methods for the development and evaluation of pharmaceutical substances. The majority of those surveyed felt that the alternatives could supplement or complement animal tests, but not replace the tests altogether. However, most favored the use of nonsentient material in safety tests.
