Attenuation Of Ultrasonic Waves: Influence Of Microstructure And Solid Fat Content, Silvana Martini, Constantin Bertoli, Maria Lidia Herrera, Ian Neeson, Alejandro Marangoni

Nutrition, Dietetics, and Food Sciences Faculty Publications

Ultrasonic technology can be used to monitor the crystallization of fats and determine solid fat content (SFC) online. Ultrasonic waves are attenuated as crystals form and grow, and this attenuation occurs first at higher frequencies. The attenuation of the ultrasonic signal does not depend on the induction times of crystallization of the systems, or on their thermal behavior; but it does depend on SFC and on microstructure, particularly on the crystal size. At low SFC values (≈5%), bigger crystals generate more attenuation. At intermediate SFC values (≈10%), crystal size does not affect signal attenuation and SFC is the key factor …

Alternative Futures For The Bear River Watershed, Richard E. Toth

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

The Bear River Watershed (BRW) is located in northeastern Utah, southeastern Idaho, and southwestern Wyoming. Over the three states the watershed encompasses an area of 7,500 square miles (4,800,000 acres). The Bear River 's headwaters begin at close to 13,000 feet in the High Uintas Wilderness Area of northeastern Utah. The course of the river follows a horseshoe pattern flowing north through Wyoming, Utah, and Idaho before bending south at Soda Springs. The river then meanders through the Gem and Cache Valleys before reaching its delta at the Great Salt Lake at an elevation of 4,211 feet.

Repeat Migration In The United States: A Comparison Of Black, Hispanic, And White Return And Onward Migrants, Beth A. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study is to examine U.S. repeat migration for blacks, Hispanics, and whites. It investigates the relationships and patterns of these different racial/ethnic groups utilizing the National Longitudinal Survey of Youth 1979 (NLSY79). Repeat migration within and across categories of individual characteristics for blacks, Hispanics, and whites, is compared in order to determine if there are differences in the overall rates of repeat migration for these groups, once other factors are controlled.

To do this several statistical procedures are utilized, and the results of selected descriptive and logistic analyses are presented. The descriptive statistics control for …

Identifying Temporal Trends In Treated Sagebrush Communities Using Remotely Sensed Imagery, Eric D. Sant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The sagebrush shrub steppe ecosystem is of great concern to researchers, conservationists, and the general public because of the documented declines associated with it. Monitoring in the past has generally been point-based and lacking in long-term data. To overcome these deficiencies, an automated method of monitoring was developed using GIS and remote sensing.

Geospatial layers of vegetation, soils, fire history, roads, streams, and springs were acquired and processed to characterize selected monitoring locations. A temporal set of Landsat satellite imagery for the past 30 years was normalized to reduce the effects of sun angle, haze, and sensor change. After normalization, …

Highway 12, Christian Probasco

All USU Press Publications

Highway 12 is undoubtedly one of not only America's but the world's most scenic highways. From its intersection on the west with Highway 89 south of Panguitch, Utah, it runs up through Red Canyon onto the Paunsagunt Plateau and across Bryce Canyon National Park. It then drops into the Paria River Valley, passes through several tiny villages, crosses some extraordinary (for anywhere but this region) badlands, and descends the Escalante River into Potato Valley. While a driver may justifiably feel she has seen some scenery by that point, the highway is just getting started, for in the next stretch, it …

Persistence Of Armor Layers In Gravel-Bed Streams, Peter Wilcock, B. T. Detemple

Watershed Sciences Faculty Publications

Streambed surfaces are typically coarsened, or armored, at low flows, but there is little evidence of their condition during floods, when significant hydraulic and ecologic disturbance occurs. Some flume experiments have been used to conclude that armor layers wash out during floods, although other experiments have produced a persistent armor layer. In the absence of clear field or flume evidence, we use a surface-based transport model in an inverse prediction of surface grain size as a function of transport rates observed in the field. The predicted surface grain size matches that observed at low flow and indicates that low-flow armor …

Positive Feedback Between Tree Establishment And Patterns Of Subalpine Forest Advancement, Glacier National Park, Montana, U.S.A., Matthew F. Bekker

Wasatch Dendroclimatology Research

The development and maintenance of several types of visually striking vegetation patterns are controlled by positive feedback between pattern and process. These patterns are particularly common at ecotones, where the influence of positive feedback may affect the position and dynamics of the boundary between the adjacent biotic communities. In this study, I use dendrochronology to examine the role of feedback between existing trees and the establishment and survival of seedlings in the advancement of linear, finger-like strips of subalpine forest in Glacier National Park, Montana. A general upslope, windward to leeward pattern of older trees followed by progressively younger trees …

Characteristic Dimensions Of The Step-Pool Bed Configuration: And Experimental Study, J. C. Curran, Peter Wilcock

Watershed Sciences Faculty Publications

The dominant dimension of the step-pool bed form is its spacing, which is determined by the locations at which large, step-forming grains are deposited. We conducted laboratory experiments involving active transport of widely sorted sediment, including large grains whose deposition readily formed steps. Direct observation of step development indicates that deposition of step-forming grains was predominantly associated with bed roughness impeding transport or with earlier flow and transport conditions not contemporaneous with step development. Neither mechanism is likely to occur at regular locations on the bed. Measured step spacing was found to follow a Poisson distribution, supporting the conclusion that …

Cooperation And Coordination Are Invasive Species: Important For Effective Management Of Invasive Weeds, U.S. Government Accountability Office

All U.S. Government Documents (Utah Regional Depository)

Invasive weeds, native or nonnative plant species, cause harm to natural areas such as rangelands or wildlife habitat and economic impacts due to lost productivity of these areas. While the federal investment in combating invasive species is substantial most has been concentrated on agricultural lands, not on natural areas. In this report, GAO describes (1) the entities that address invasive weeds in natural areas and the funding sources they use; (2) federal, state, and local weed management officials’ views on the barriers to weed management; and (3) their opinions about how additional resources for weed management could be distributed. GAO …

The Politics Of Scale, Position, And Place In The Governance Of Water Resources In The Mekong Region, Louis Lebel, Po Garden, Masao Imamura

All UNF Research

The appropriate scales for science, management, and decision making cannot be unambiguously derived from physical characteristics of water resources. Scales are a joint product of social and biophysical processes. The politics-of-scale metaphor has been helpful in drawing attention to the ways in which scale choices are constrained overtly by politics, and more subtly by choices of technologies, institutional designs, and measurements. In doing so, however, the scale metaphor has been stretched to cover a lot of different spatial relationships. In this paper, we argue that there are benefits to understanding—and actions to distinguish—issues of scale from those of place and …

Anonimo Mexicano, Richley Crapo, Bonnie Glass-Coffin

All USU Press Publications

Transcribed from the original Nahuatl manuscript (written circa 1600) and translated into English for the first time, this epic chronicle tells the preconquest history of the Tlaxcalteca, who migrated into central Mexico from the northern frontier of the Toltec empire at its fall. By the time of Cortés's arrival in the sixteenth century, the Tlaxcalteca were the main rivals to the Mexica, or Aztecs, as they are commonly known. One of the few peoples of central Mexico not ruled from the Mexica capital city of Tenochtitlan, the Tlaxcalteca resided in the next valley to the east and became Cortés's powerful …

Junius And Joseph: Presidential Politics And The Assassination Of The First Mormon Prophet, Robert S. Wicks, Fred R. Foister

All USU Press Publications

"Junius and Joseph examines Joseph Smith's nearly forgotten [1844] presidential bid, the events leading up to his assassination on June 27, 1844, and the tangled aftermath of the tragic incident. It... establishes that Joseph Smith's murder, rather than being the deadly outcome of a spontaneous mob uprising, was in fact a carefully planned military-style execution. It is now possible to identify many of the key individuals engaged in planning his assassination as well as those who took part in the assault on Carthage jail. And furthermore, this study presents incontrovertible evidence that the effort to remove the Mormon leader from …

A Further Consideration Of Galdosian Cultural Nicknames: Mythological, Legendary, And Historical Personages, Vernon A. Chamberlin

Decimonónica

Galdós’s use of nicknames has been addressed both directly and indirectly in various studies,¹ but much remains to be noted about how historical, legendary, and mythological personages served as source material for sobriquets to designate Galdosian characters. So important were these nicknames to Galdós’s artistry that he would sometimes change the apodo in the Alpha manuscript to a different one in the final printed version. Moreover, the history-based nicknames, which do so much to enliven Galdós’s novels and Episodios are a feature in common with other nineteenth-century novelists, most notably Alas, Pereda, and Pardo Bazán.

Geosciences Faculty Publications

Aim: Among the various possible approaches to assess whether a species is native or introduced, the analysis of subfossil pollen and spores from natural archives is a valuable tool. Requirements include a sufficiently high taxonomic resolution of the pollen morphology, as well as sufficient temporal and spatial resolution. The aim of this study is to show the usefulness of this method in solving whether the taxon is native or introduced.

Location: The results are derived from two islands of the Azores: Flores and Pico. Methods: Analysis of pollen and spores in lake sediments; radiocarbon dating of the studied sediments.

Results: …

Intra-Guild Compensation Regulatesspecies Richness In Desert Rodents, J. Goheen, Ethan P. White, S.K. Morgan Ernest, J. H. Brown

Biology Faculty Publications

Evidence from numerous studies suggests that species richness is an emergent property of local communities. The maintenance of species richness, despite changes in species composition and environmental conditions, requires compensatory colonization and extinction events with species coming from a regional pool. Using long-term data from a rodent community in the Chihuahuan Desert, we use randomization methods to test the null hypothesis that changes in species richness occur randomly. We find that the dynamics of species richness differ significantly from a random process, and that these nonrandom dynamics occur largely within the most speciose guild. Finally, we propose a general framework …

Diabetes Stepping Up To The Plate: An Education Curriculum Focused On Food Portioning Skills, D. Pauline Williams, Heidi Leblanc, Nedra K. Christensen

Nutrition, Dietetics, and Food Sciences Faculty Publications

The Diabetes Stepping up to the Plate program was developed to determine the effectiveness of food portion based diabetes education. One hundred fifty-one individuals enrolled in the diabetes series. Food portion knowledge and skills tests, height, weight, and waist-to-hip ratio (WHR) were measured pre- and post-program. Data was analyzed through paired t-tests and correlations. Evaluation showed a decrease in HbA1C, waist/hip circumference, WHR, and BMI, and an improvement in food portion knowledge and skills. Seventy-five participants completed pre- and post-data collection parameters, although more participants completed all classes in the series. Extension can play a role in successful diabetes education.

This protocol is designed to make the process of assessing and listing invasive plants objective and systematic, and to incorporate scientific documentation of the information used to determine each species’ rank. NatureServe’s methodology has previously included assessments of the conservation significance of native species; this …

The Real World Of Language Instruction: Cache Valley Teachers Speak Out On The Challenges They Face While Teaching Grammar, Shauna Wight

Undergraduate Honors Capstone Projects

"Discussing grammar in the teachers' lounge is a little like stepping in between two opposing 350-pound NFL linemen just after the ball is snapped," says Harry Noden, veteran English teacher and author of Image Grammar (Noden vii). With this statement, Noden captures the intensity and hostility that has characterized departmental meetings, university classrooms, and scholarly articles in which the issue of grammar has been disputed. Relying upon this football metaphor, Noden aptly describes the precarious situation language arts teachers face when they enter the profession and one of its greatest debates-grammar instruction-an issue in which all English teachers inevitably become …

Snow Avalanche Disturbance In Intermountain Spruce-Fir Forests And Implications For The Spruce Bark Beetle (Coleoptera: Scolytidae), Elizabeth G. Herbertson

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

Spruce beetle outbreaks are the primary biotic disturbance affecting forests in the Intermountain spruce-fir zone. Major snow avalanches can produce large quantities of host material for spruce beetle colonization; however, few studies have examined the influence of avalanche disturbance on outbreak initiation. The purpose of my research was to investigate potential relationships between these two disturbance agents. In the first study, I used dendro-ecological analyses to date major avalanche years on the Wasatch Plateau in south-central Utah, and then determined what climate factors were associated with avalanche occurrence. The results indicated that mean January snowfall was significantly related to the …
