Aboriginal Exploitation Of Marine Food Resources, Alan J. Osborn

Department of Anthropology: Theses and Student Research

Anthropological interest in human exploitation of resources has increased considerably during the last decade. Archaeological and ethnological literature concerning man's utilization of the world's oceans is relatively abundant and there are now several on-going anthropological research programs, e.g., Aleutian Islands, Pacific Northwest Coast, California, Hawaii, Australia, New Zealand, Peru, Ecuador, Chile, and Southern Africa which focus primarily on maritime adaptations. The purpose of this study is threefold: (1) to suggest that anthropological assumptions regarding marine food resources and their use are inadequate; (2) to examine marine ecosystems with respect to structure and dynamics, primary productivity, ecological efficiencies, distributional and quantitative …

X-Linked Diseases With Cataract, Philip J. Howard

Henry Ford Hospital Medical Journal

X-linked cataracts are a rare group and appear as a complication of other disease. Changes in the lens are difficult to visualize and the family history may alert the examiner to the possibility of cataractous changes. This paper is a review of 13 sex-linked conditions with cataract as a possible complication. Cataracts may be present in an occasional case or in some instances in every case. Short abstracts follow of Fabry's disease, glucose 6-dehydrogenase deficiency, myotonic dystrophy, ectodermal hypohidriotic dysplasia, oculocerebral syndrome, keratosis follicularis spinulosa decalvans with cataract, Norrie disease, incontinenti pigmenti, hypoparathyroidism due to a sex-linked recessive trait, pseudohypopara-thyroidism, …

Alfalfa Response To Varying Rates Of Phosphorus And Potassium Fertilization On Deep, Red, Limestone - Derived Soils Of The Pennyroyal Area In Kentucky, H. C. Vaught, Kenneth L. Wells, K. L. Driskill

Agronomy Notes

The Western Pennyroyal area of Kentucky consists largely of deep, well-drained limestone-derived soils occurring on an undulating to rolling landscape. A thin loess mantle overlies the limestone residuum in many areas. Soils on these landscapes are capable of good crop production, providing the basis of the rather intensive grain-hay- tobacco-livestock farming systems common to the Pennyroyal area. Because of the well-suited physical characteristics of these soils, alfalfa is a very important hay crop to this area.

An Analysis Of Species Recognition In Sympatric, Allopatric And Reciprocally Cross-Fostered Peromyscus Californicus And Peromyscus Eremicus (Rodentia, Cricetidae), Ronald L. Carter

Loma Linda University Electronic Theses, Dissertations & Projects

Experiments were performed to compare homospecific and heterospecific mate selection in two closely related species, Peromyscus californicus and Peromyscus eremicus. Comparisons were made between allopatric and sympatric populations and between males and females for mate selection performance. Both species made significant choice for the homospecific chambers. Significant homospecific choice was made by mice from sympatric populations, whereas allopatric populations did not demonstrate significant choice. No significant difference in choice performance was demonstrated between males and females even when the estrus stages of the females were controlled.

A comparison of different testing lengths and temporal regimes of data collection was performed …

Climatic Implications Of Barbados Coral Growth, Richard E. Dodge, Karl K. Turekian, J. Rimas Vaisnys

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Results from a coral growth band analysis utilizing samples of M. annularis from the Recent Barbados reef and from three fossil raised reefs (Barbados I, II, and III dated at 82,000, 105,000, and 125,000 yrs. B.P.) indicate that in the Barbados II collection both average band width and variability were lower than in the other samples. We suggest the climate during formation of the 105,000 yrs. B.P. reef was significantly different than that of the present.

An Investigation Of The Effects Of A Dietary Calcium And Vitamin D Supplement On The Resorption Of The Alveolar Ridge Of The Jaw In Immediate Denture Patients, Peter Brussee

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to investigate the possible effects of a calcium and vitamin D supplement on the resorption of alveolar bone following teeth extractions in human subjects. Studies have been cited which indicate a positive relationship between adequacy of calcium intake and maintenance of the bones of the jaw.

In this investigation, patients who received dentures immediately after the extraction of their remaining natural teeth were given a medication to take every day for a year.

Half the subjects received a calcium and vitamin D supplement while half received a placebo. As it was a double—blind study, …

Browse Evaluation And Survey Techniques For The Uinta North Slope Moose Herd, William H. Babcock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was conducted on the North Slope of the Uinta Mountains from January, 1972 through June, 1974, to determine the effects of three simulated levels of moose utilization on the crude protein content, phosphorus content, digestibility and vigor of willow plants. A comparison was also made on the crude protein content, phosphorus content and digestibility of current year's versus past years' willow growth. Finally, the validity of direct and indirect population enumeration methods was compared for the possible development of a standardized moose survey technique.

Clipping caused a highly significant increase in crude protein and phosphorus content between treatment …

Consumption, Digestion, And Utilization By Goats Of The Dry Matter And Nitrogen In Diets Containing Oak (Quercus Gambelii) Foliage, Anastasios Stefanos Nastis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Part I
A study of animal performance was made with goats fed, ad libitum ground and pe11eted mixtures of Gambe1 oak and alfalfa. Intake, digestibility, metabolizable nitrogen, and metabolized energy of oak diets were generally lower than those for a control alfalfa diet. However, no significant differences in live weight gains of experimental animals were found. No apparent toxicity was detected in goats fed diets containing up to 80 percent oak for 72 days.

Part II
Mixtures of oak (Quercus gambelii) and alfalfa (Medicago sativa) were used to evaluate three laboratory techniques, the Tilley and Terry …

Diet Composition And Activities Of Elk On Different Habitat Segments In The Lodgepole Pine Type, Uinta Mountains, Utah, William B. Collins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The biweekly diets of tame elk (Cervus canadensis nelsoni) were established on a species dry-weight basis for different habitat segments of the lodgepole pine (Pinus contorta) type, Principal species in the diets (5% or more) on each habitat segment were generally composed of preferred species. However, some highly abundant but non-preferred species took on principal dietary status, whereas some preferred species, scarce in the vegetation, contributed less than 5 percent to diets. Forbs contributed most to total consumption; grasses and sedges were the second largest contributors. Browse appeared to be of limited importance, but mushrooms had …

Forage Preferences Of Mule Deer In The Lodgepole Pine Ecosystem, Ashley National Forest, Utah, Joseph A. Deschamp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the summer of 1976, five tame, trained mule deer (Odocoileus hemionus hemionus) were used to determine botanical composition and relative preference of mule deer diets on five habitat segments in the lodgepole pine (Pinus contorta) ecosystem of northeastern Utah. Diets were statistically analyzed according to estimated weight consumption per unit of time spent feeding on the different segments. Habitat segments sampled were: clearcut forest, dry and wet meadow, mature forest, and stagnated forest.

Diets differed between segments mainly because of differences in plant species available and their abundance. The diets in the non-forested segments averaged …

Importance Of Legumes, Especially The Trifolium Species, In Range Improvement, Abdelhai A. Ibnattya

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This paper analyzes the most important characteristics of legumes, which have led to their utilization in range improvement all over the world. It emphasizes the Trifolium spp. (esteemed among the legume family), their contributions to soil a n d forage improvement, and the success obtained from their utilization, especially in semi-arid ranges. Many references originally from Australia, United States, Morocco, and Portugal were used as sources of data because of the ample utilization of these species in these countries. Careful analysis related to requirements, potentialities, and production of clovers were used and recommendations were made for different ecological areas where …

Energy Usage Trends, Energy-Food Conversion Efficiency, And Relative Energy Efficiency Of Primary Crop Agriculture, Estimated From Energy-Nutrient Conversion Ratios In Mexico, India, United States, And Japan, Gerald L. Blight

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Energy-nutrient conversion ratios, as a measure of relative agricultural efficiency for Mexico, India, in the United States, and Japan between 1951 and 1974, were calculated for protein, B-vitamins, calcium, iron and food energy production. Estimates from the different nutrient ratios showed a range in percent change of production efficiency over the twenty-four year period. Indian estimates were the most consistent with only a 7 percent variability. Japan (23 percent), United States (42 percent), and Mexico (43 percent) each showed greater variability in their efficiency estimate ranges from aggregate energy-nutrient conversion ratios. Japan was the only country for which negative trends …

A Self-Instructional, Multi-Media Approach To Facilitate The Teaching Of The Index Of Nutritional Quality, Claudia Kay Probart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A review of the literature dealing with nutrition education established the following: (a) that there is a need for nutrition education at the elementary school level; (b) that elementary teachers do not always have the background or motivation to meet this need for nutrition education; and (c) that new educational methods that are easier to understand and more highly motivating are needed.

The Index of Nutritional Quantity (INQ), a nutrient density concept, was developed at Utah State University to answer the need for easily understood and motivating nutrition information. The INQ method of nutrition education has been used and considered …

The Iron Bioavailability Of Mechanically-Deboned Meats, Bonnie Rae Anderson Farmer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two separate experiments were used to investigate iron bioavailability of mechanically-deboned meats using hemoglobin regeneration to measure iron utilization. In both studies, male weanling rats were made anemic by bleeding and being fed a low-iron diet. Experimental diets were control fed to the animals and final hemoglobin concentrations were recorded. Animals were sacrificed and liver iron concentrations determined. The first experiment measured the iron bioavailability of mechanically-deboned and hand-deboned beef plate was better utilized by rats than the iron from mechanically- deboned shank and mechanically-deboned plate. The effect of lipid source and level on iron bioavailability of mechanically-deboned turkey meat …

A Field Study In The Use Of Dietary And Urinary Variables In Determining Osteoporosis In Elderly People, Jane Steger Osborn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three-day dietary records were analyzed for nutrient content and 24 hour urine samples were analyzed for calcium, phosphorous, total nitrogen, and free alpha-amino nitrogen for 210 elderly people. Dietaries and urine samples were collected twice, October and March at five month intervals, for each subject. Increases were found in both dietary intake and urinary components October to March. Based on a criteria of high dietary protein, low dietary calcium, high urinary nitrogen and low calcium, 23 subjects were selected as osteoporotic and and 25 were selected as non-osteoporotic. This method of prediction was not supported by radiological evaluations.

Persistence Of Mucor Miehei Protease In Cheddar Cheese And Pasteurized Whey And Its Effect On Sterile Milk Products, Randall Kirk Thunell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whey from a commercial cheese plant, taken at draining on five separate days, from cheese made with a Mucor miehei coagulant was cooled within 1 h to 4 C. Portions were adjusted from pH 4.2 to 6.4 at .2 pH intervals and subjected to HTST pasteurization at 73.9, 76.6, and 79.5 C for 25 sec. Milk clotting activity in whey was determined before and after pasteurization. Resistance to heat in-activation increased with decreasing pH. All measurable activity was destroyed above pH 5.4 by pasteurization at 79.5 C, above pH 5.8 at 76.6 C and above pH 6.0 at 73.9 C. …

The Relationship Of Molybdenum To Iron Status In Pregnancy And Anemia In Rats And Humans, Jo Ann Mortensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Weanling male rats were made anemic and fed diets supplemented with 20 ppm iron and/or 2 ppm molybdenum. A decrease in serum iron was observed in the rats supplemented only with iron and a significant decrease in hemoglobin was observed in rats given no supplementation.

In a second experiment, pregnant female rats were also fed diets supplemented with 20 ppm iron and/or 2 ppm molybdenum. An inverse relationship was apparent between iron and copper in both the serum and the liver of the female rats. The livers of their pups displayed an inverse relationship between molybdenum and copper. Hemoglobin in …

Milko-Tester Analysis Of Milkfat Content Of Churned And Nonchurned Samples From Jersey And Holstein Dairy Cattle, Kazuko Monobe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk samples from three Jersey and three Holstein herds were used to determine if the degree of churning correlated with the initial milkfat assay, and also to determine if the churned milkfat could be measured as accurately as the initial milkfat using the Milko-Tester.

Regression lines for the initial milkfat test versus churned milk- fat test fit polynomial curves. The degree of churning was greater for Jerseys than Holsteins and correlated with the initial milkfat test.

The repeatability of initial milkfat tests vas 0.98 for Jerseys and 0.99 for Holsteins. However, the repeatability of churned milkfat tests was lower for …

The Development And Evaluation Of A Nutrient Density Based Nutrition Education Program For Elementary Schools, Guendoline Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A behavioral objective based nutrition education program for kindergarten through sixth grade which allowed nutrition education to be integrated into existing classroom programs was developed and evaluated. A nutrient density approach served as the conceptual framework for the program. Nutrient density evaluates the nutrient content of a food in relationship to the caloric content. Materials for student use, teacher use and teacher training were developed.

The program was evaluated in 27 classrooms in nine public elementary schools in Utah and Idaho with 806 student participants. Pre- and post tests as well as classroom evaluations were conducted.

Students, teachers and parents …

A Process Incorporating Ultrafiltration Concentrated Whey Solids Into Cheese For Increased Cheese Yield, Rodney Jay Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A process which incorporates whey sol ids, primarily protein, into cheese to increase cheese yield and eliminate whey handling problems was evaluated. Whey was concentrated by ultrafiltration to levels of 9.8 to 20.3 percent total solids (4.3 to 7.1 percent protein), heated at 70 C for 30 minutes and added to cheese milk with the coagulating enzyme.

Increase in cheese yield, on the basis of 39 percent moisture, for 10 pairs of samples was 4.0 ± 2.8 (S.D.) percent. This increase was significant at alpha less than 0.001. Moisture and protein content increased while fat content decreased. Setting time and …
