Predictive Formula For Electron Range Over A Large Span Of Energy, Anne C. Starley

Reports

A model developed by the Materials Research Group that calculates electron penetration range of some common materials, has been greatly expanded with the hope that such extensions will predict the range in other, perhaps, more interesting materials. Developments in this extended model aid in predicting the approximate penetration depth into diverse classes of materials for a broad range of energetic incident electrons (10 MeV, with better than 20% accuracy). The penetration depth—or range—of a material describes the maximum distance electrons can travel through a material, before losing all of its incident kinetic energy. This model has started to predict a …

“Whatdunit?” Developmental Changes In Children's Syntactically Based Sentence Interpretation Abilities And Sensitivity To Word Order, James W. Montgomery, Julia L. Evans, Ronald B. Gillam, Alexander V. Sergeev, Mianisha C. Finney

Communicative Disorders and Deaf Education Faculty Publications

Aim 1 of this study was to examine the developmental changes in typically developing English-speaking children’s syntactically-based sentence interpretation abilities and sensitivity to word order. Aim 2 was to determine the psychometric standing of the novel sentence interpretation task developed for this study, as we wish to use it later with children with Specific Language Impairment (SLI). Children listened to semantically implausible sentences in which noun animacy and the natural affordance between the nouns were removed, thus controlling for event probability. Using this novel “whatdunit?” agent selection task, 256 children 7-11 years listened to two structures with canonical word order …

Strain Hardening And Anisotropy During Tensile Testing Of Sheared Model Mozzarella Cheeses, Prateek Sharma, Peter A. Munro, Tzvetelin T. Dessev, Peter G. Wiles, E. Allen Foegeding

Nutrition, Dietetics, and Food Sciences Faculty Publications

We studied the tensile fracture properties of model Mozzarella cheeses with varying amounts of shear work input (3.3–73.7 kJ/kg). After manufacture, cheeses were elongated by manual rolling at 65°C followed by tensile testing at 21°C on dumbbell-shaped samples cut both parallel and perpendicular to the rolling direction. Strain hardening parameters were estimated from stress–strain curves using 3 different methods. Fracture stress and strain for longitudinal samples did not vary significantly with shear work input up to 26.3 kJ/kg and then decreased dramatically at 58.2 kJ/kg. Longitudinal samples with shear work input <30 kJ/kg demonstrated significant strain hardening by all 3 estimation methods. At shear work inputs <30 kJ/kg, strong anisotropy was observed in both fracture stress and strain. After a shear work input of 58.2 kJ/kg, anisotropy and strain hardening were absent. Perpendicular samples did not show strain hardening at any level of shear work input. Although the distortion of the fat drops in the cheese structure associated with the elongation could account for some of the anisotropy observed, the presence of anisotropy in the elongated nonfat samples reflected that shear work and rolling also aligned the protein structure.

Effect Of Shear Work Input On Steady Shear Rheology And Melt Functionality Of Model Mozzarella Cheeses, Prateek Sharma, Peter A. Munro, Tzvetelin T. Dessev, Peter G. Wiles, Robert J. Buwalda

Nutrition, Dietetics, and Food Sciences Faculty Publications

Model Mozzarella cheeses with varied amounts of shear work input were prepared by working molten cheese mass at 70 °C in a twin screw cooker. Rheology and melt functionality were found to be strongly dependent on total shear work input. A non-linear increase in consistency coefficient (K from power law model) and apparent viscosity and decrease in flow behaviour index (n from power law model) were observed with increasing amounts of accumulated shear work, indicating work thickening behaviour. An exponential work thickening equation is proposed to describe this behaviour. Excessively worked cheese samples exhibited liquid exudation, poor melting and poor …

Testing The Concurrent Validity Of A Naturalistic Upper Extremity Reaching Task, Sydney Y. Schaefer, C. R. Hennge

Kinesiology and Health Science Faculty Publications

Point-to-point reaching has been widely used to study upper extremity motor control. We have been developing a naturalistic reaching task that adds tool manipulation and object transport to this established paradigm. The purpose of this study was to determine the concurrent validity of a naturalistic reaching task in a sample of healthy adults.This task was compared to the criterion measure of standard point-to-point reaching. Twenty-eight adults performed unconstrained out-and-back movements in three different directions relative to constant start location along midline using their nondominant arm. In the naturalistic task, participants manipulated a tool to transport objects sequentially between physical targets …

Predictive Formula For Electron Range Over A Large Span Of Energies, Anne C. Starley, Gregory Wilson, Lisa Montierth Phillipps, Jr Dennison

Posters

A model has been developed to predict the approximate penetration depth into diverse classes of materials for a broad range of energetic incident electrons (<10 eV to >10 MeV, with better than 20% accuracy). The penetration depth—or range—of a material describes the maximum distance electrons can travel through a material, before losing all of its incident kinetic energy. This model leads to a predictive formula that estimates the penetration depth for materials without the need for supporting data, but rather using only basic material properties and a single fitting parameter (Nv, described as the effective number of valence electrons). Nv …

Disordered Speech Disrupts Conversational Entrainment: A Study Of Acoustic-Prosodic Entrainment And Communicative Success In Populations With Communication Challenges, Stephanie A. Borrie, Nichola Lubold, Heather Pon-Barry

Communicative Disorders and Deaf Education Faculty Publications

Conversational entrainment, a pervasive communication phenomenon in which dialogue partners adapt their behaviors to align more closely with one another, is considered essential for successful spoken interaction. While well-established in other disciplines, this phenomenon has received limited attention in the field of speech pathology and the study of communication breakdowns in clinical populations. The current study examined acoustic-prosodic entrainment, as well as a measure of communicative success, in three distinctly different dialogue groups: (i) healthy native vs. healthy native speakers (Control), (ii) healthy native vs. foreign-accented speakers (Accented), and (iii) healthy native vs. dysarthric speakers (Disordered). Dialogue group comparisons revealed …

The Multifaceted Interaction Of Pain Perception In Collegiate Athletes, Kristen Leigh Bartiss

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

Deepening the present understanding of the multidimensional nature of athlete perceptions of pain requires attention to three specific gaps. First, the field currently lacks fundamental knowledge regarding the relationship between an individual’s athletic identity and the role of the brain in deciphering and responding to painful stimuli. Because athletes view injury as a potential loss of identity and thus a significant part of themselves (International Olympic Committee, n.d.), the severity they ascribe to pain is both conceptually and practically relevant. Second, the field has yet to fully explore the specific areas of the brain associated with subsequent functional connectivity as …

Dose Response Relationship Between Aquatic Treadmill Running And Change To Si In Land Treadmill Running, Luke Campbell Roberts

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

Aquatic therapies have been used in some of the earliest human civilizations. Examples can be seen in China, ancient Rome and even in the early history of U.S. settlements.^1,2 Over the past few years aquatic environments have become a more common method for rehabilitation, injury prevention, and cross training. Additionally, research has observed that aquatic exercise may assist in pain relief, swelling reduction, and ease of movement due to the pressure and warmth of water.⁷ Aquatic environments can also be used to reduce forces placed on the lower extremities by reducing the weight of the subject through buoyancy. …

Validity And Reliability Of A-Mode Ultrasound For Body Composition Assessment Of Lean, Division I Athletes, Dustin L. Cain

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

Athletes strive for a competitive advantage, and for some athletes building a lean body with a low body fat percentage (%BF) can help them achieve a higher level of performance. This is particularly the case in gravitational sports in which a high body mass hinders performance, in aesthetic sports in which there is a perceived ideal shape, and in weight class sports in which competition is organized into categories of body mass (20). However, some athletes put themselves at risk of health problems through extreme dieting, disordered eating, and fluid restriction in an effort to achieve a particular weight or …

Comparison Of Propulsive Power During Loaded Countermovement Jumps Performed In Water Versus Land In College Aged Males, Clint R. Nardoni

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

As use of an aquatic environment increases as a training and rehabilitative tool, the purpose of this study was to assess peak propulsive power in loaded countermovement jumps (CMJ) in water and compare them to loaded CMJ on land. 20 college aged (24.6±3.6 years) recreationally active males performed 4 randomized countermovement jumps on a force plate with increasing loads (bodyweight [BW], BW+10%, BW+20%, BW+30%) in two environments: immersed in water at the xiphoid process and on land. Peak power (PP) and mean power (MP) normalized to apparent mass were assessed for all jumps. A 2 (environment) by 4 (load) repeated …

Wingate Anaerobic Test Methods For Power-Trained Males Using Velotron, Nicolas W. Clark

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

The purpose of this study was to examine the effects of two methodologies (start method and sprocket size) of the Wingate Anaerobic Test (WAnT) on peak power (PP) and mean power (MP). Twenty power-trained males (24.6 ± 4.5 years; 25.4 ± 2.5 BMI) with the same exercise routine for the past 4 months performed, in a randomized order, four WAnT with different combinations of start method, flying (FLY) or stationary (STA), and front sprocket size, 62-tooth sprocket (S-62) or 85-tooth sprocket (S-85), using the Velotron Racermate®. The results showed main effects for start method (p < 0.001; ES 0.753) and sprocket size (p < 0.001; ES 0.69) for PP and MP, respectively. For PP, significantly (p < 0.001) higher mean differences were shown for both FLYs (14.4 w/kg) while MP showed significant (p < 0.01) increases for S-85 in combination with the FLY (10.9 W/kg) and for S-85 in combination with the STA (9.7 W/kg). Pearson correlation (r) revealed no significant relationship between same start methods, FLY (p > 0.05; r = 0.227) or …

Effects Of Differential Rates Of Alternative Reinforcement On Resurgence Of Human Behavior: A Translational Model Of Relapse In The Anxiety Disorders, Brooke M. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Brooke M. Smith, graduate student in the Combined Clinical, Counseling, and School Psychology program at Utah State University, proposed and completed this thesis in partial fulfillment of the requirements of Master of Science in Psychology.

Anxiety disorders are the most common psychological disorders in the world, and they place a substantial burden on society. Although successful psychological treatments for anxiety are available, many people still experience relapse once treatment ends. When consequences that follow a behavior increase its future probability, this is termed “reinforcement.” One common treatment approach for anxiety is to attempt to decrease problematic behavior, such as avoidance, …

The Role Of Medical Comorbidities On The Risk For Severe Dementia, Institutionalization, And Death In Alzheimer's Disease: A Population Study In Cache County, Utah, Mac J. Gilbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alzheimer’s disease is a progressive disease that impairs cognitive and functional abilities. Without a cure, it is estimated there will be 81 million cases of Alzheimer’s disease by 2040. Life for the individual with Alzheimer’s disease, and their family, changes drastically when the affected individual experiences significant problems with memory, thinking, and ability to complete daily tasks. Some become so debilitated that they need to be placed in a nursing home for supportive care. Until a cure is discovered, it will be important to identify what can be done to help those with Alzheimer’s disease minimize time spent experiencing severe …

Pregenomic And Genomic Effects Of 24,25-Dihydroxyvitamin D3, Yang Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the United States, the major dietary source of protein is poultry meat, particularly chicken. Phosphorus absorption in chickens is a critical problem in poultry production. It therefore is important to understand the cellular and molecular regulation of phosphorous absorption in intestine to increase efficiency of the process. This would provide the benefits of reducing feed costs and reducing phosphorous excretion, thereby contributing to the sustainability of agriculture in the United States. Therefore, the focus of this thesis is determining the effect of vitamin D metabolites involved in phosphate homeostasis using the chicken as a model.

Electron Penetration Range For Diverse Materials, Anne C. Starley, Lisa M. Phillipps, Jr Dennison

Posters

The penetration range of energetic electrons into diverse materials can be modeled approximately with a simple fit. This fit is a function of a single parameter, Nv, which describes the effective number of valence electrons. Using the Continuous-Slow-Down-Approximation (CSDA) for energy deposition in a material, a composite analytical formula has been developed which estimates the range or maximum penetration depth of incident electrons for energies from10 MeV with an uncertainty of

Measurement Techniques For Steady Shear Viscosity Of Mozzarella-Type Cheeses At High Shear Rates And High Temperature, Prateek Sharma, Tzvetelin T. Dessev, Peter A. Munro, Peter G. Wiles, Graeme Gillies, Matt Golding, Bryony James, Patrick Janssen

Nutrition, Dietetics, and Food Sciences Faculty Publications

While measuring steady shear viscosity of Mozzarella-type cheeses in a rotational rheometer at 70 °C, three main difficulties were encountered; wall slip, structural failure during measurement and viscoelastic time dependent effects. Serrated plates were the most successful surface modification at eliminating wall slip. However, even with serrated plates shear banding occurred at higher shear rates. Because of the viscoelastic nature of the cheeses, a time dependent viscous response occurred at shear rates <1 >s−1, requiring longer times to attain steady shear conditions. Prolonged continuous shearing altered the structure of the molten cheeses. The effects of structural change were greatly reduced by …

Understanding Hunting Constraints And Negotiation Strategies: A Typology Of Female Hunters, Elizabeth Covelli Metcalf, Alan R. Graefe, Nate E. Trauntvein, Robert C. Burns

Kinesiology and Health Science Faculty Publications

This article examined a typology of female hunters, factors constraining participation, and negotiation strategies females used to overcome constraints. A survey of Oregon hunters was conducted in the summer of 2010 to understand hunting characteristics using the 2008 big game license database (n = 392). We created a typology of female hunters using a cluster analysis of Recreation Experience Preference items. Four clusters were identified: less-engaged, family oriented, nature-sport, and all around enthusiast. Analysis of variance revealed differences among female hunter segments. Differences existed among the four groups on both constraints and negotiation strategies. One of the notable groups was …
