The Petrology And Mineralogy Of Tertiary(?) Olivine Trachyte In The Harrington Peak Quadrangle, Southeastern Idaho, Amanda Shearer-Fullerton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Harrington Peak Quadrangle is located within the Caribou National Forest of southeast Idaho. Within this quadrangle are outcrops of olivine trachyte of Pliocene(?) age overlying sedimentary rocks of Mississippian to Tertiary age. The region contains thrust faults and later normal faults (generally trending north-south} formed during Basin and Range extension.

The Largest outcrop of olivine trachyte (approximately1 1/2 X 3 km) probably formed as the result of a fissure eruption. Two other outcrop areas show evidence of being sites of local extrusion.

Whole-rock chemical analyses revealed the olivine trachyte to have moderate amounts of SiO₂ and Al_{2O …}

Habit Reversal Treatment Of Bulimia Nervosa, Ken Small

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although several writers have emphasized the habit-like characteristics of bulimia nervosa, no study has investigated the extent to which bulimia responds to treatment specifically for habit disorders. Habit reversal is a general treatment plan which teaches individuals to regain lost awareness of all aspects of a habit. The habit is then interrupted at the earliest movement in the chain by a physically competing response. Habit reversal (Azrin & Nunn, 1973) has been effective in treating other habits (e.g., stuttering, tics, bruxism). In the present study, habit reversal was adapted for the treatment of bulimia.

In response to newspaper advertisements, ten …

A Comparison Of Evaluation Models For Handicap Intervention In A Head Start Program, Carin Niebuhr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Beta-Endorphin And Running Addiction: Use In The Treatment Of Schizophrenia, Mania, Depression, And Anxiety, James Glenn Rogers

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

Neither Glasser's (1976) survey data nor popular magazine articles (which seldom cite references) have provided conclusive evidence regarding the existence of running addiction or established causality between this addiction and Beta-endorphin. An integration and summarization of research on the effects of opiates, Beta-endorphin and running will answer the following question, or indicate where evidence is insufficient and explore avenues that require further research.

• Question 1: Is distance running addictive and if so, what is the role of Beta-endorphin in this addiction?

Secondly, prior reviews of research of the effects of opiates and Beta-endorphin on psychopathological illnesses will be combined with …

Summary Of The Results Of Analysis Of Obsidian Artifacts From The Maya Lowlands, F. W. Nelson

Scanning Electron Microscopy

The analytical method of X-ray fluorescence spectrometry has been used to analyze obsidian artifacts from Cerros, Belize and from Yaxchilan, Chiapas, Mexico. The results of these analyses are compared to the results of analysis of obsidian geologic sources using graphical and statistical methods in order to identify the probable source from which the obsidian for the artifacts came. These results are then summarized along with results of analysis by others of obsidian artifacts from several archaeological sites in the Lowland Maya area. Using these data, possible trade routes and how they may have changed through time have been postulated.

Structural Changes In Mouse Small Intestinal Villi Following Lower Body Hyperthermia, H. M. H. Kamel, K. E. Carr, S. P. Hume, J. C. L. Marigold

Scanning Electron Microscopy

Heating an exteriorised loop of mouse small intestine resulted in marked changes in the shape of the villi as reported earlier. However, the exteriorisation techniques resulted in non-uniformity in both temperature and effect around circumference of intestine and, in addition, the extent to which handling contributed to the observed damage was not known. The work has therefore been extended using lower-body heating in the temperature range 37.5° - 43.0°C.

Heating in the temperature range 37.5° to 41.0°C produced minimal to moderate structural changes, manifested as scattered, vertically collapsed villi amongst predominantly "normal" villi. No villi showed conical or rudimentary forms …

Near Edge Fine Structures On Electron Energy Loss Spectroscopy Core Loss Edges, C. Colliex, T. Manoubi, M. Gasgnier, L. M. Brown

Scanning Electron Microscopy

Core edges recorded in Electron Energy Loss Spectroscopy (EELS) display a large variety of profiles. We have investigated several specific aspects concerning Energy Loss Near Edge Structures (ELNES) and emphasize the interest in a careful edge shape analysis to obtain refined microanalytical information, such as local symmetry. After indicating the general impact of EELS fine structures as compared to EDX and Auger spectroscopies we discuss the instrumental conditions required for recording satisfactory spectra and consider the theoretical problems which are involved in data interpretation. The major portion of this paper presents results for selected K, L23, M45 and N45 core …

Causality In Utah's Cattle Prices, Soumendra N. Ghosh, Donald L. Snyder, Deevon Bailey

Economic Research Institute Study Papers

Price fluctuations in any industry are a serious concern to the economic agents (decision makers) participating in that industry. This point becomes more critical if the industry is the principal one in any particular geographic area.

Maximizing Regional Gross Output In A Constrained Setting, John E. Keith, Luis Martinez, Donald L. Snyder, Terrence F. Glover

Economic Research Institute Study Papers

Most regional policy-makers have, as one of their important policy goals, some form of maximization of regional economic activity. Obtaining maximum output, employment, and income from a state's, or region's, resource base appears to be central to many planning and policy agencies. For example, the State of Utah considered limiting the sources of coal for new electrical generation plants in the state, to in-state coal fields through legislative or administrative fiat. While such a policy was not implemented, it represents the conviction that verticle integration within a region will increase that region's economic welfare. The wide-spread use of industrial revenue …

The Size Distribution Of Bovine Casein Micelles: A Review, C. Holt

Food Structure

This review considers the average size and size distribution of bovine casein micelles as measured by electron microscopy, light scattering and controlled pore glass chromatography, and the origin and biological function of the size distribution.

Recent work by electron microscopy has given average sizes in reasonable agreement with measurements on the same milk sample by light scattering . It is suggested that natural variations in averaqe micelle size and overestimation of micelle radii by light scattering methods as well as deficiencies in electron microscopical methodology were responsible for past discrepancies.

Electron microscopy and controlled pore glass chromatography provide evidence that …

Response Of Grass Species To Tree Harvesting In Singleleaf Pinyon-Utah Juniper Stands, United States Department Of Agriculture, Forest Service

Forestry

Cover, yield, and nutrient concentrations of grasses were sampled on tree-harvested and nonharvested plots on north, west, and south aspects of a singleleaf pinyon (Pinus monophylla)-Utah juniper (Juniperus osteosperma) stand. Grass cover increased rapidly the first 2 years following tree harvest, but the rate of increase declined over the next 2 years. Grass yield varied among aspects and soil microsites on tree-harvested plots but not on the nonharvested plots where tree competition masked aspect and microsite effects. All grass species had greater yield and greater percentage nitrogen and phosphorus on harvested than on nonharvested plots. Low digestibility of some species …

Ultrastructural Ultilization Of Plants By Herbivores, L. H. Harbers

Food Structure

Study of the patterns of ruminal digestion of forages enhances the nutritional knowledge of how specific plant tissues are digested and adds its own dimension by characterizing the specific cells and the complex interactions of ruminal microflora with those tissues. A common pattern of digestibility exists for mono- and dicotyledon leaves: mesophyll and phloem are degraded readily, and sclerenchyma slowly, whereas cuticle and the remaining vascular tissues are rarely utilized . Digestion of stems is limited to parenchymal tissues in monocotyledons and to cortex and parenchyma in dicotyledons. Epidermal silica and cuticle are undigestible and restrict microbial entrance. Calcium oxalate …

Release Of A Thinned Budworm-Infested Douglas-Fir/Ponderosa Pine Stand, United States Department Of Agriculture, Forest Service

Forestry

Current and past defoliation by western spruce budworm (Choristoneura occidentalis Freeman) in an 80-year-old predominantly Douglas-fir (Pseudotsuga menziesii var. glauca [Beissn.] Franco) stand thinned to 14 by 14 feet was significantly lower than in a nearby untreated stand of similar age, species, and site conditions. Analysis of periodic radial growth ratios indicated that prior to thinning, Douglas-fir had been heavily defoliated by budworm and growth was seriously depressed. Following thinning, the host leave trees developed dense crowns and 10-year radial growth increased an average of 57 percent: meanwhile, radial growth of nonhost ponderosa pine (Pinus ponderosa Dougl.) increased 38 percent. …

Application Of Electron Spin Resonance Techniques To Model Starch Systems, L. E. Pearce, E. A. Davis, J. Gordon, W. G. Miller

Food Structure

Starch model systems were examined by electron spin resonance (ESR) techniques with either 16-DOXYL-stearic acid or TEMPO spin probes in water or hexane. Room temperature starchwater- 16-DOXYL-stearic acid spectra showed strong adsorption occurred between the starch and probe. Starch-water-TEMPO spectra at room temperature did not show strong adsorption between starch and probe, but did show some slowed motion of the probe as a result of different local environments experienced by the probe within the starch granule. Starch-water-probe spectra from systems heated from 45-95° C showed no major differences from unheated samples. Also, no major spectral differences existed for each starch …
