The Effect Of Dietary Fat Level On Tumor Development And Immunity In Balb/C Mice Fed Casein Of Wheat Gluten As Protein And Challenged With Herpes Type 2-Transformed Cells, Helen Drakou

Loma Linda University Electronic Theses, Dissertations & Projects

A high percentage of fat in the diet has been implicated through epidemiological studies in several human cancers. Studies in experimental animals have produced evidence that increasing the fat in the diet decreases the animal’s ability to restrict tumor development and growth. In previous work done in this laboratory with BALB/c mice injected with herpes simplex Type 2-transformed mouse cells (H238), the effects of a diet which greatly enhanced tumor growth was compared with one which restricted tumor growth. The latter, a low (5%) fat, low protein diet, in which the protein was casein, was also found to produce a …

Alkali Extraction Test As A Predictor For Self-Heating In Coal, Arshad Parvez

Masters Theses & Specialist Projects

The self-heating of coal is a serious problem that has always affected the coal industry. Self-heating has been studied around the world for more than 100 years by many investigators, yet no accurate method of predicting self-heating in coal has been developed.

The objective of this research was to investigate the factors contributing to the self-heating in coal and to develop methods to predict the self-heating in coal and to develop methods to predict the self-heating susceptibility of various coals. A data bank containing analytical data, transportation histories, and results from laboratory tests was established at Western Kentucky University. A …

Mechanisms Of Crustal Deformation In The Western United States, United States, National Aeronautics And Space Administration

Geology

The basic purpose of the research carried out under this grant was to obtain a better understanding of deformation processes in the western United States. The research considered both deterministic models and random or statistical models. One important aspect of deformation is the rheology of the lithosphere. We have been one of the leading proponents of an intracrustal asthenosphere. This is a soft zone at mid-crustal depths that has an important effect on a variety of tectonic phenomena.

Relationship Between The P And S Fresnel Reflection Coefficients Of An Interface Independent Of Angle Of Incidence, R. M.A. Azzam

Electrical Engineering Faculty Publications

The Fresnel reflection coefficients r_p and r_s of p- and s-polarized light at the planar interface between two linear isotropic media are found to be interrelated by (r_s - r_p)/(1 - r_sr_p) = cos 2β, independent of the angle of incidence ø, where tan²β = ∊ and ∊ is the (generally complex) ratio of dielectric constants of the media of refraction and incidence. This complements another relation (found earlier), (r²_s - r_p)/(r_s - r_sr_p) = …

Benthic Foraminifera And Paleoenvironments Of The Arcola Limestone Member Mooreville Formation (Campanian) In Eastern Mississippi And Western Alabama, Julia K. Palmer

OES Theses and Dissertations

Eighty-one species of benthic foraminifera have been recovered from chalky marls of the upper Mooreville Formation including the Arcola Limestone Member, and the basal Demopolis Formation located in five sections in east-central Mississippi and west-central Alabama. These species have been described and seventy-nine illustrated. Analysis of the environmental or depth preferences of abundant species together with planktonic percentages and benthic species diversity, indicates that the chalky marls were deposited in a broad shallow shelf sea (subtidal conditions less than 100m) greatly influenced by open ocean conditions. The benthic assemblage is composed of a mixture of typically neritic and bathyal species …

Evaluation Of Packed Towers For Removing Volatile Organics From Surface Waters, James W. Moore

Arkansas Water Resources Center Technical Reports

This study analyzes the potential of packed tower aeration as a remedial treatment process for the removal of trace organics on either an acute or chronic basis. Both pilot-scale installations of the packed tower process were reviewed. Included are basic modeling considerations for the removal of volatile trace organics from raw water. Included also is an assessment of the state of the technology as applied to air stripping of water.

Factors Affecting Epithecal Growth Lines In Four Coral Species, With Paleontological Implications, Jean-Luc Liénard

Loma Linda University Electronic Theses, Dissertations & Projects

The number of epithecal (external) growth lines was surveyed over 124 days for Montastrea annularis growing at different depths (3.5 m to 61 m). There was a significant (P< .01) decrease in the number of lines with depth. Although the linear regression is significant, there is evidence for a logarithmic or quadratic relationship, and more data from greater depths are needed to determine which of these gives a better fit.

The number of growth lines formed during light-dark cycles of 16, 24 and 32 hours were compared for M. annularis, M. cavernosa, Porites astreoides and Tubastrea aurea. The variability among colonies from the same species was in many cases more significant than that among light treatments. This is a serious problem for anyone counting lines in corals, especially from a few specimens; therefore conclusions based on such counts seem hazardous on …

Characterization Of Microorganisims After Feeding With Phenolic Compounds : Comparing A Domestic Sludge To An Industrial Sludge, Dianne Adamowitz

Theses

This study examined the effects of phenolic compounds on the populations in mixed liquors obtained from two very different treatment plants: the Passaic Valley Sewerage Commissioners plant in Newark, and the Livingston, NJ municipal treatment plant. The dominant organisms were identified initially and after ten days exposure to phenol (100 ppm), and either 2-chlorophenol (20 ppm) or 2,6-dichlorophenol (10 ppm) in aerated batch reactors.

Results confirmed the remarkable similarity between the two mixed liquor populations, in spite of the significant differences in the operation of the two treatment plants.

Solar- Terrestrial Physics: A Space Age Birth, R. W. Schunk

Faculty Honor Lectures

Solar- Terrestrial Physics, in its broadest sense, is concerned with the transport of energy, particles, and fields from the sun to the earth and their consequent effect on the terrestrial environment. Most of the solar energy eventually deposited in our atmosphere, at a rate of approximately a trillion megawatts, arrives in the form of visible light. The study of how this energy affects our environment falls within the purview of meteorology, a discipline that has experienced an independent development and that has sufficiently different problems from solar-terrestrial physics that it can be regarded as a separate but neighboring discipline. In …

Comparison Of Four Infiltration Models In Characterizing Infiltration Through Surface Mine Profiles, Larry G. Wells, A. D. Ward, I. D. Moore, R. E. Phillips

Biosystems and Agricultural Engineering Faculty Publications

A laboratory infiltrometer system was used to evaluate the infiltration process through reconstructed surface mine profiles. Six different profiles were subjected to constant simulated rainfall intensities for selected test conditions. Surface runoff rates were monitored and transient soil moisture contents in the profiles were measured with a gamma density gauge. Unsaturated hydraulic conductivity relationships were determined using Campbelfs method and the "zero-flux" procedure. The infiltration process was modeled by the SCS curve number method, a form of Holtan's equation, the Green-Ampt model and Richards' equation. SCS curve numbers were determined by fitting the method to the observed results. Richards' equation …

Boron Composition Of Alfalfa In Utah As Related To Soils And Irrigation Waters, Robert N. Radtke Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Eighteen field plots at 15 locations were selected throughout the state to evaluate the status of the boron content in irrigation waters, soils, and alfalfa (Medicago sativa) plant tissue under irrigated conditions.

No boron deficiency symptoms were observed in any of the alfalfa plants at any of these locations, nor were any of the plant tissue boron levels inadequate. Only two locations were found in which the alfalfa plants exibited toxicity symptoms. These locations were along the Indian and Antelope Creeks in Duchesne County which contain high boron levels in the water. All the alfalfa and soil tested …

Magnesium, Copper And Zinc Concentrations In Blood From Children With Diabetes Mellitus, Linda Lowers Jenkins

Chemistry & Biochemistry Theses & Dissertations

Trace element levels in blood from diabetic children were investigated and compared to control children. Plasma, erythrocyte, mononuclear and polymorphonuclear cells were analyzed for magnesium, copper, and zinc content. Leukocyte separation was performed by density gradient centrifugation on Ficoll-Hypaque, followed by washing steps to remove platelet contamination and hypotonic lysis to remove red cell contamination. Polarized Zeeman-effect atomic absorption spectroscopy was used for trace metal analysis.

Decreased plasma magnesium levels were observed in the diabetic children. This finding is well documented and probably due to increased urinary magnesium loss from glycosuria. Lymphocyte magnesium levels in the diabetic children were also …

Implications And Management Of Feral Mammals In California, Walter E. Howard, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 12th (1986)

"Feral" is defined. For each of the principal species of feral mammals in California we note the broad ecological implications they have on the environment and the potential or actual management approaches being followed. The main emphasis of this paper, and all of the slides shown, was on how wild horses and burros, two controversial feral species, are managed in California and in other western states. The feral pig is about to become the number one big game animal in California, and mustrats (Ondatra zibethica (L.)), which were introduced or escaped into the Sacramento Valley—-hence locally feral--are the state's …

An Integrated Approach To Bubonic Plague Control In A Southwestern Plague Focus, Curtis E. Montman, Allan M. Barnes, Gary O. Maupin

Vertebrate Pest Conference Proceedings: 12th (1986)

Plague is widespread among rodents and their fleas in the western United States, but most human cases occur in several definable, ecologically unique, and geographically limited high risk areas in the Southwest and Pacific Coast states. Control strategies to prevent human cases in high risk areas must vary from one epizootic focus to another, depending on such basic ecological factors as rodent/flea species involved; their distribution, abundance, seasonality, and relationship with the plague organism; climatic factors that affect transmission; the lifestyles of human residents; and others. This paper briefly summarizes preliminary results of a long-term program to define human risk …

The Complexities At The Interface Among Domestic/Wild Rodents, Fleas, Pets, And Man In Urban Plague Ecology In Los Angeles, County, California, Bernard C. Nelson, Minoo B. Madon, Arthur Tilzer

Vertebrate Pest Conference Proceedings: 12th (1986)

Bubonic plague was first found in Los Angeles County in 1908. The largest epidemic of pneumonic plague in the United States occurred in the county in 1924, and the last cases of plague associated with domestic rodents in the United States occurred here in 1925. Sporadic plague activity was recorded from 1925 to 1975. Since 1975, plague has been found annually and is now endemic in the San Gabriel Mountains and the interface, that area where suburban encroachment intermingles with wilderness areas along the southern edge of these mountains. Within these two areas, plague is amplified and is a risk …
