Clinical, Genetic, And Biochemical Studies Of A Family With Gardner's Syndrome, Edwin W. Naylor

Biology

In 1951, Gardner (American Journal of Human Genetics, 3:167-176) reported that multiple polyposis followed a pattern of autosomal dominant inheritance in a Utah kindred, In 1952, Gardner and Plenk (American Journal of Human Genetics, 4:31-36) reported that all members of this family with polyposis also had multiple osteomas. In 1953, these same patients were found to have epidermoid cysts, fibromas, and ill-defined masses of connective tissue. In 1958, Smith (Diseases of the Colon & Rectum, 1: 323-332) suggested the term Gardner's syndrome to describe this spectrum of inherited pathological changes. Contact was re-established with this original kindred, and the pedigree …

The Effects Of Temperature And Photoperiod On The Imaginal Diapause Of The Alfalfa Weevil, Hypera Postica (Gyllenhal), Larry H. Bennett

Biology

The developmental stage which is responsible for the photoperiodic induction of diapause in the alfalfa weevil was determined by subjecting an increasing number of developmental stages to a long-day photoperiod (16 hours) and subsequently transferring them to a short-day photoperiod (8 hours). Adults which did not oviposit by 90 days after emergence were considered to be in diapause. Exposure of the larval and pupal stages to the long-day photoperiod resulted in 32-47% diapausing adult females, which was similar to a control group reared entirely at the short-day photoperiod. However, when the adult stage was exposed to the long-day photoperiod for …

Experimental Coccidian Infections In Captive Hibernating And Non Hibernating Uinta Ground Squirrels, Spermophilus Armatus, Larry C. Anderson

Biology

Uinta ground squirrels were captured and kept in wire cages in the laboratory. Each of 111 of these squirrels was inoculated during periods from August through November, 1967 to 1969, with 40,000 or 100,000 to 1,000,000 sporulated oocysts of Eimeria bilamellata, E. larimerensis, or E. callospermophili, before or after being placed, without food and water, into a chamber maintained at 7 C. Only juvenile hibernators were used in trials with E. bilamellata and E. larimerensis whereas adults and juveniles were used in trials with E. callospermophili. Each of 121 juvenile and adult squirrels was inoculated with …

Time And Motion Study Of Agonistic Behavior In The Red Jungle Fowl, Gallus Gallus, Richard Howard Wilson

Biology

Agonistic postures of Red Jungle Fowl hens were studied during initial pair encounters, and during the introduction of strangers into established flocks, using time and motion analysis of motion picture films. The posture of each hen was quantitatively determined by measuring the angles of the trunk, neck and tail to the horizontal. These three measurements were added to obtain a posture index. Comparisons were made of postural measurements for the same individual in contests which it won and in contests which it lost. No statistically significant difference could be demonstrated, but a trend for the neck angle and posture index …

Fine Structural Study Of The Exogenous And Asexual Endogenous Stages Of Eimeria Callospermophili, William Liddell Roberts

Biology

The occyst walls, sporocysts, excystation, and the development of first generation schizonts and merozoites of Eimeria callospermophili were studied. The different stages were fixed with Karnovsky's fixative or 5 percent glutaraldehyde and post-fixed with 2 percent osmium tetroxide or in 2. 5 percent glutaraldehyde and 2.5 percent osmium tetroxide together for electron miscoscopy. The oocyst wall had an outer layer consisting of columnar projections and an inner layer consisting of an outer band covered by a membrane and an electron-dense inner band. A membrane covered the sporocyst wall. Inside were 2 sporozoites, fluid which coagulated during fixation, and a membranebound …

Radiation Biology Of The Greater Wax Moth (Galleria Mellonella (L.)): Effects On Developmental Biology, Bionomics, Mating-Competitiveness And F1 Sterility, Ross Albert Nielsen

Biology

Males and females of the greater wax moth were irradiated with gamma rays during various ages of eggs, larvae, pupae, and adults. Survivors were mated with untreated moths and spermatophore transfer, oviposition, egg hatch, and adult development were studied. The F₁ progeny were also mated to untreated moths and similar observations made. Males from selected irradiated and F₁ groups were tested for mating competitiveness with untreated males. Females were more sensitive to irradiation than males, and fewer females than males developed to the adult stage in both the irradiated and the F₁ generation. Irradiation of either parent …

A Comparative Study Of The Mutationally Unstable Mutants Forked-3n And White-Ivory Of Drosophila Melanogaster, Ronny C. Woodruf

Biology

The unstable Drosophila melanogaster mutants f³ⁿ (1-56.7 and wⁱ (1-1.5) have been observed to revert frequently to wild type with similar parameters of reversion. Therefore, it was the objective of this investigation to critically compare the properties of the f³ⁿ reversion event to previously reported data on wⁱ reversion and to determine if the two phenomena are truly similar. After confirming the previously reported spontaneous and X-ray-induced f³ⁿ reversion frequencies, it was determined that f³ⁿ reversion events in homozygous females are independent of recombination of outside markers. This is consistent with the properties of …

Ultrastructural Observations Of Cellular Differentiation In Testes Of The South African Clawed Toad (Xenopus Laevis Daudin). Normal Development And Development Of Experimentally Sterilized Embryonic Gonads, Samuel C. Reed

Biology

An ultrastructural study of cellular differentiation in embryonic and mature testes of Xenopus laevis was made. Primordial germ cells were identified in the dorsal mesentery at a stage prior to gonad formation. The primordial germ cells of Xenopus possess all the characteristics common to primordial germ cells of other species, but in addition possess a highly lobate nucleus. This nuclear configuration suggests that primordial germ cells in Xenopus are metabolically quite active cells. Cells possessing the lobate nucleus and similar in size and morphology to primordial germ cells in the dorsal mesentery and early gonad can be found in all …

Twelve groups of weanling rats were fed with diets prepared by diluting the basal diet with 0 to 75 percent sucrose for 46 days and their antibody response was measured on the 28th, 40th and 46th day using Salmonella pullorum as the antigen. The rats fed the diet containing 75 percent sucrose and 25 percent basal diet had mean antibody …

Computer Simulation Of Urban Runoff Characteristics Within Salt Lake County, Robert Newman Parnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A hybrid computer program is developed to simulate the outflow hydrographs of two urban watersheds located within Salt Lake County, Utah. The gaged outflow of the watersheds provided a checkpoint for comparing the observed and the simulated final outflow hydrographs.

The outflow hydrographs for each subzone of the two watersheds were obtained by abstracting interception, infiltration and depression storage from each subzone hyetograph. The outflow of the subzones were routed to the Jordan River, the final outflow point of the two watersheds. The final hydrographs of the watersheds were combined and compared with the gaged flow.

The uniquenesses of this …

Statistical Analysis For Tolerances Of Noxious Weed Seeds, Yadolah Dodge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An analysis of the previous method for testing tolerances of noxious weed seeds was performed. Problems of the current techniques were discussed, and the solution to these problems was given.

A new technique of testing through the sequential test ratio was developed, and results examined.

The sequential test was found to be useful enough to include the use of it in determining tolerances for noxious weed seeds.

This study did show that the use of sequential tests does have excellent potential and flexibility as a statistical tool for the tolerances of noxious weed seeds.

Effects Of Water Quality On Physico-Chemical And Organoleptic Characteristics Of Selected Canned Fruits And Vegetables, Anita Kay Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of processing water quality, specifically calcium and magnesium salt content (0-500 mg/1) and the addition of chelating agents (0-250 mg/1 of aminopolycarboxylic acids, polyphosphates, hydroxycarboxylic acids or phytates), upon physico-chemical and organoleptic characteristics of canned Jonathan and Delicious apple slices, Montmorency cherries and Blue Lake green beans was investigated.

Physical determinations: shear values, turbidity of syrup or brine measured via light transmittance, Hunter color and color difference meter readings and internal can corrosion; chemical composition: pectin as calcium pectate, volatile reducing substances, total acidity, pigment determinations, nitrate-nitrogen values; and sensory measurements: texture, shape, flavor, aroma, color value and …

Optimum Enterprise Combinations For Representative Farms In Seven Counties Of Southwestern Utah, 1967, James F. Maxwell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Resources available for agricultural production were ascertained and trends in their use were studied for seven counties of southwestern Utah. Special consideration was given to cropland, irrigation water, and operating capital as resource restrictions for a linear programming model. Budget data were obtained for crop and livestock enterprises by interviewing farmers and ranchers in the area. Budgets for four representative farm types representing climatic and irrigation differences were made to study crop possibilities. Acreage minimums or maximums for selected crops were established as conservation measures. Budgets were prepared for farm livestock enterprises to use with crop budgets for each representative …

The Changing Role Of The Secondary Counselor In Career Guidance, Norman D. Devries

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

Work can be viewed as man's aim in life, or as his instrument to achieve other goals. Whatever the view, it is wrong to allow the vagueness and error that many individuals frequently face when choosing a career. If we are going to meet this demand, it will be necessary to make vocational guidance available to all those who are making or will make a vocation choice.

Investigation Of Urolithiasis Occurring In Hatchery-Reared Trout In Utah, Ernest H. Dean Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The urolithiasis condition investigated occurred at a "hard water" hatchery in Utah after the trout were changed from a meat diet to a commercial pelleted fish feed as a sole sustaining diet in 1961. Numerous diet modifications proved unsuccessful in preventing urolithiasis at the hatchery. It was eventually determined that different commercial diets resulted in varied percentages of trout developing urolithiasis. The urolithic deposits found in the kidney tubules were amorphous and composed of calcium phosphate (apatite) and an organic matrix. Bacterial contamination of the kidneys was not an important factor in the formation of urolithiasis. Rainbow trout containing urolithic …

Comparison Of The Effects Of 97 Per Cent And 21 Per Cent Oxygen Mixtures Upon Recovery From Treadmill Running Among Male Wrestlers At Utah State University, Michael P. Brooks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparison of the effects on recovery while breathing a 97 per cent oxygen mixture and normal compressed atmospheric air after treadmill running was determined among nine male wrestlers at Utah State University. The variables examined were heart rate and percentages of oxygen and carbon dioxide in expired air. The practice of some athletic teams of administering oxygen to participants during time out periods was the motivation for this study.

A great majority of the studies reviewed conclude that oxygen does not play a significant role in aiding recovery from physical activity.

The experiment first consisted of eight runs on …

Relationship Of The Self-Concept To Selected Measures Of Performance Among Male Navajo Students At Intermountain School, Melvern Eugene Graham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship of various measures of high school performance and a measure of the self-concept were examined for the 1970-71 senior male students at Intermountain School, Brigham City, Utah. Some significant correlations were found.

Their junior year vocational training grade and grade point average were found to be significantly correlated to their self-definition score, as ere all but one of the teachers' subjective evaluations.

General aptitude, reading ability, previous years at Intermountain, and class grouping were not found to show any significant correlation with the self-definition test score. Age was found to be correlated at the .01 level with the …
