title: Pyrolysis of Acrylonitrile-Butadiene-Styrene (ABS) Under High Heat Flux Conditions
Creators: name: Wilson, James R.
Publisher: name: Utah State University
Year: 2013

description: Acrylonitrile-butadiene-styrene (ABS) is a common industrial plastic that is widely used for structural and piping applications. Additionally, within the past decade ABS has become the most popular material used in a type of rapid prototyping known as fused- deposition modeling (FDM). Within the past three years, ABS plastic blends have also been investigated as a potential fuel for hybrid- and solid-propelled rocket systems, exhibiting promising results. Because the use of ABS as a rocket propellant is very recent, a pyrolysis database, describing how ABS will burn, at the temperatures and heating rates experienced by rocket systems does not exist. Previous pyrolysis tests were performed for �re-prevention tests, at heating rates that were nearly an order of magnitude lower than those experienced during rocket combustion. This report investigates the properties of ABS as it is heated to temperatures over 500◦ C. The resulting surface regression rates are measured and plotted against temperature to create an Arrhenius-type curve that allows important pyrolysis and kinetic combustion parameters, such as heats of gasification and activation energy, to be calculated. Accurate knowledge of these parameters is essential to improve modeling of the combustion performance of ABS as a fuel for solid and hybrid rocket systems.

description: A phenomenological approach to the ferromagnetic two dimensional Potts model on square lattice is proposed. Our goal is to present a simple functional form that obeys the known properties possessed by the free energy of the q-state Potts model. The duality symmetry of the 2D Potts model together with the known results on its critical exponent α allow to fix consistently the details of the proposed expression for the free energy. The agreement of the analytic ansatz with numerical data in the q=3 case is very good at high and low temperatures as well as at the critical point. It is shown that the q>4 cases naturally fit into the same scheme and that one should also expect a good agreement with numerical data. The limiting q=4 case is shortly discussed.

description: In this article we propose to simulate acoustic black holes with ions in rings. If the ions are rotating with a stationary and inhomogeneous velocity profile, regions can appear where the ion velocity exceeds the group velocity of the phonons. In these regions phonons are trapped like light in black holes, even though we have a discrete field theory and a nonlinear dispersion relation. We study the appearance of Hawking radiation in this setup and propose a scheme to detect it.

title: Starting Early: Perceptions of Parents and Teachers on 6th to 12th Grade Transition Timeline for Students with High-Incidence Disabilities
Creators: name: Nielsen, Josie M.
Publisher: name: Utah State University
Year: 2013

description: Post-secondary educational and employment outcomes for students with high- incidence disabilities continue to lag far behind their nondisabled peers. A carefully designed timeline including evidence-based transition skills and practices may serve as a guideline for teachers and parents as they prepare student /child with high-incidence disabilities for successful transition into adulthood. This project examined the importance and age/grade-appropriateness of skills/activities on a transition timeline, based on ratings by teacher and parent focus groups. Participants included eight secondary teachers with at least10 years experience, and five parents of children with high-incidence disabilities who graduated from both high school and post-secondary school. Thirteen individuals participated in separate focus groups consisting of (a) parents (n=5), (b) middle-school teachers (n=5), and (c) high school teachers (n=3). Focus groups rated items on a scale of 1-4 for both importance and age/grade-appropriateness, then discussed each item. Data were analyzed based on median and range scores for each item, and the items were rank ordered according to importance and age/grade-appropriateness to produce a timeline of transition skills/activities for both parents and teachers. A final survey was given to participants to validate the timeline as a valuable resource to guide both parents and teachers.
Damping via the hyperfine interaction of a spin-rotation mode in a two-dimensional strongly magnetized electron plasma

Publisher: name: arXiv
Year: 2021
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We address damping of a Goldstone spin-rotation mode emerging in a quantum Hall ferromagnet due to laser pulse excitation. Recent experimental data show that the attenuation mechanism, dephasing of the observed Kerr precession, is apparently related not only to spatial fluctuations of the electron Landé factor in the quantum well, but to a hyperfine interaction with nuclei, because local magnetization of GaAs nuclei should also experience spatial fluctuations. The motion of the macroscopic spin-rotation state is studied microscopically by solving a non-stationary Schrödinger equation. Comparison with the previously studied channel of transverse spin relaxation (attenuation of Kerr oscilations) shows that relaxation via nuclei involves a longer quadratic stage of time-dependance of the transverse spin, and, accordingly, an elongated transition to a linear stage, so that a linear time-dependance may not be revealed.

description: The ability to make meaningful comparisons between theoretical and observational data of star-forming regions is key to understanding the star formation process. In this paper we test the performance of INDICATE, a new method to quantify the clustering tendencies of individual stars in a region, on synthetic star-forming regions with sub-structured, and smooth, centrally concentrated distributions. INDICATE quantifies the amount of stellar affiliation of each individual star, and also determines whether this affiliation is above random expectation for the star-forming region in question. We show that INDICATE cannot be used to quantify the overall structure of a region due to a degeneracy when applied to regions with different geometries. We test the ability of INDICATE to detect differences in the local stellar surface density and its ability to detect and quantify mass segregation. We then compare it to other methods such as the mass segregation ratio $Λ_{\rm{MSR}}$, the local stellar surface density ratio $Σ_{\rm{LDR}}$ and the cumulative distribution of stellar positions. INDICATE detects significant differences in the clustering tendencies of the most massive stars when they are at the centre of a smooth, centrally concentrated distribution, corresponding to areas of greater stellar surface density. When applied to a subset of the 50 most massive stars we show INDICATE can detect signals of mass segregation. We apply INDICATE to the following nearby star-forming regions: Taurus, ONC, NGC 1333, IC 348 and $ρ$ Ophiuchi and find a diverse range of clustering tendencies in these regions.

description: This portfolio is a compilation of the author’s research-supported ideas on what good language teaching looks like. The central component is the teaching philosophy, in which the author explains that respect for individuality, use of technology, and use of culture as context for learning are the three elements seen as most important for successful language learning.The teaching philosophy is supported by artifacts about peer feedback in language learning, literacy in adult English as a Second Language learners, and autonomy in culture learning. Finally, in three annotations the author branches out from the pillars of the teaching philosophy and examines place-based education, portfolio-based language assessment, and game-based learning and their relationships with the teaching philosophy.
title: A History of Facilities, Programs, and Services for Utah's Women Inmates
Creators: name: Shulsen, Kenneth B.
Publisher: name: Utah State University
Year: 1996

description: I spent my first night behind bars when I was about ten years
old. My father was the associate warden at the Utah State Prison,
and had been called to the prison because of an emergency. Since my
mother was out of town, I had the opportunity to accompany my
father to the prison. I will never forget the overwhelming feeling as
the huge iron bars opened and we were admitted to the penitentiary.
I was instantly introduced to screams and profanity from the
inmates, I felt like I had left Utah and entered a strange new world,
indeed I had. Fortunately for me, I spent the remainder of the night
in my father's office. Yet, I recall wondering what the men and
women had done to end up in this miserable place. The events of
that night sparked an interest in prisons that has lasted until the
present.
This paper is the culmination of the fascination I have had
with penal institutions since my youth. Writing on the Utah prison
as partial fulfillment of my Masters degree was a natural topical
choice. Once I began to research the prison, and study what other
scholars had produced on the subject, I noticed a gap in the
historiography. Several historians had written about Utah's penal
history, but, there was little if any mention of prison conditions,
programs and services, or facilities designed specifically for
women inmates. To tell the saga of female prisoners in Utah, the
development of penal institutions for men and women on a national
level, the philosophical and religious ideology behind the settlement
of the Salt Lake valley, and the establishment of prison facilities in
Utah must first be told. Once the grassroots have been discussed,
the unique history concerning women inmates in Utah can be
presented. This work is an attempt to bring to light the long
struggle for penological equality women have endured in the Utah
territory and subsequent state.
Artificial Insemination in Poultry: Revolutionizing Modern Farming

Year: 2025

description: Introduction

Artificial insemination (A.I.) has significantly transformed poultry farming by offering a more efficient alternative to natural mating. This is particularly beneficial for large, heavily muscled birds like commercial turkeys and broilers, where natural reproduction can be challenging. A.I. enhances fertility rates, provides better breeding control, and increases overall productivity. Through this technique, farmers can selectively breed for desirable traits, improve biosecurity measures, and address physical breeding limitations in poultry. Artificial insemination (AI) in chickens is primarily utilized in selective breeding programs, research, and commercial layer or broiler breeding to improve genetic traits and regulate mating.

description: Obtaining conductance spectra for a concentration of disordered impurities distributed over a nanoscale device with sensing capabilities is a well-defined problem. However, to do this inversely, i.e., extracting information about the scatters from the conductance spectrum alone, is not an easy task. In the presence of impurities, even advanced techniques of inversion can become particularly challenging. This article extends the applicability of a methodology we proposed capable of extracting composition information about a nanoscale sensing device using the conductance spectrum. The inversion tool decodes the conductance spectrum to yield the concentration and nature of the disorders responsible for conductance fluctuations in the spectra. We present the method for simple one-dimensional systems like an electron gas with randomly distributed delta functions and a linear chain of atoms. We prove the generality and robustness of the method using materials with complex electronic structures like hexagonal boron nitride, graphene nanoribbons, and carbon nanotubes. We also go on to probe the distribution of disorders on the sublattice structure of the materials using the proposed inversion tool.

description: Let $k$ be a field of characteristic zero, let $G$ be a connected reductive algebraic group over $k$ and let $\mathfrak{g}$ be its Lie algebra. Let $k(G)$, respectively, $k(\mathfrak{g})$, be the field of $k$-rational functions on $G$, respectively, $\mathfrak{g}$. The conjugation action of $G$ on itself induces the adjoint action of $G$ on $\mathfrak{g}$. We investigate the question whether or not the field extensions $k(G)/k(G)^G$ and $k(\mathfrak{g})/k(\mathfrak{g})^G$ are purely transcendental. We show that the answer is the same for $k(G)/k(G)^G$ and $k(\mathfrak{g})/k(\mathfrak{g})^G$, and reduce the problem to the case where $G$ is simple. For simple groups we show that the answer is positive if $G$ is split of type ${\sf A}_{n}$ or ${\sf C}_n$, and negative for groups of other types, except possibly ${\sf G}_{2}$. A key ingredient in the proof of the negative result is a recent formula for the unramified Brauer group of a homogeneous space with connected stabilizers. As a byproduct of our investigation we give an affirmative answer to a question of Grothendieck about the existence of a rational section of the categorical quotient morphism for the conjugating action of $G$ on itself. The results and methods of this paper have played an important part in recent A. Premet's negative solution (arxiv:0907.2500) of the Gelfand--Kirillov conjecture for finite-dimensional simple Lie algebras of every type, other than ${\sf A}_n$, ${\sf C}_n$, and ${\sf G}_2$.

description: Ultra-high energy cosmic rays generate extensive air showers in Earth's atmosphere. A standard approach to reconstruct the energy of an ultra-high energy cosmic rays is to sample the lateral profile of the particle density on the ground of the air shower with an array of surface detectors. For cosmic rays with large inclinations, this reconstruction is based on a model of the lateral profile of the muon density observed on the ground, which is fitted to the observed muon densities in individual surface detectors. The best models for this task are derived from detailed Monte-Carlo simulations of the air shower development. We present a phenomenological parametrization scheme which allows to derive a model of the average lateral profile of the muon density directly from a fit to a set of individual Monte-Carlo simulated air showers. The model reproduces the detailed simulations with a high precision. As an example, we generate a muon density model which is valid in the energy range 1e18 eV < E < 1e20 eV and the zenith angle range 60 deg < theta < 90 deg. We will further demonstrate a way to speed up the simulation of such muon profiles by three orders of magnitude, if only the muons in the shower are of interest.

description: The relativistic wave equation for spin-1/2 particles in the interior Schwarzschild solution in the presence of a uniform magnetic field is obtained. The fully relativistic regime is considered, and the energy levels occupied by the particles are derived as functions of the magnetic field, the radius of the massive sphere and the total mass of the latter. As no assumption is made on the relative strengths of the particles' interaction with the gravitational and magnetic fields, the relevance of our results to the physics of the interior of neutron stars, where both the gravitational and the magnetic fields are very intense, is discussed.

title: Landscape and Habitat Attributes Influencing Beaver Distribution
Creators: name: Leary, Ryan John
Publisher: name: Utah State University
Year: 2012

description: Removal of beaver across the North America landscape from the 1600s through the 1800s has played a major influence on the alteration of stream and riparian resources. Degradation of riparian habitats has negatively impacted many wildlife and fish species, including species listed under the Endangered Species Act. The ability of beavers to modify stream ecosystems offers a unique opportunity to restore these habitats. Many private and government agencies are working towards using beaver as a restoration tool, not only for better functioning ecosystems but also to benefit humans. Taking the big picture look, beaver and their ability to modify the environment are viewed by describing the ecological benefits and impacts to stream ecosystems and influences on fish habitat and populations; analyzing landscape and habitat attributes influencing beaver distribution using data from a large scale stream and riparian monitoring program (Pacfish/Infish Biological Opinion Effectiveness Monitoring (PIBO EM); the human dimension aspects and how beaver can be used to benefit humans in a sustainability framework; the economic incentives of using beaver for stream restoration; and, policies, laws, and administrative considerations associated with beaver.
PIBO EM Preliminary data from PIBO EM suggests that as beaver populations make a comeback they will occupy a diverse range of habitats. The data demonstrates that beaver occupy a wide range of landscape characteristics and site habitats, but particular attributes are more important than others in determining where beaver are present. The overlap of so many landscape, site, and vegetation attributes between sites with and without beaver activity and given the vast majority of PIBO EM sites are currently without beaver, indicates that many areas may already be suitable for beaver occupation, providing optimism for beaver restoration opportunities. Many groups and organizations are spending money, effort, and time into developing habitat criteria and habitat suitability indexes for beaver reintroductions. Collaborative efforts with PIBO EM would offer data and information from a large geographical area, saving valuable resources to be used for more effective beaver management. Although beaver populations have been affected by removal from trapping and loss of habitat through urbanization, as beaver populations increase they will occupy much of their former range, restoring degraded habitats for the betterment of both mankind and fish and wildlife.
Spin and valley ordering of fractional quantum Hall states in monolayer graphene

description: We study spin and valley ordering in the quantum Hall fractions in monolayer graphene at Landau level filling factors $ν_G=-2+n/3$ $(n=2,4,5)$. We use exact diagonalizations on the spherical as well as toroidal geometry by taking into account the effect of realistic anisotropies that break the spin/valley symmetry of the pure Coulomb interaction. We also use a variational method based on eigenstates of the fully $SU(4)$ symmetric limit. For all the fractions we study there are two-component states for which the competing phases are generalizations of those occurring at neutrality $ν_G=0$. They are ferromagnetic, antiferromagnetic, charge-density wave and Kékulé phases, depending on the values of Ising or XY anisotropies in valley space. The varying spin-valley content of the states leads to ground state quantum numbers that are different from the $ν_G=0$ case. For filling factor $ν_G=-2+5/3$ there is a parent state in the $SU(4)$ limit which has a flavor content $(1,1/3,1/3,0)$ where the two components that are one-third filled form a two-component singlet. The addition of anisotropies leads to the formation of new states that have no counterpart at $ν_G=0$. While some of them are predicted by the variational approach, we find notably that negative Ising-like valley anisotropy leads to the formation of a state which is a singlet in both spin and valley space and lies beyond the reach of the variational method. Also fully spin polarized two-component states at $ν=-2+4/3$ and $ν=-2+5/3$ display an emergent $SU(2)$ valley symmetry because they do not feel point-contact anisotropies. We discuss implications for current experiments concerning possible spin transitions.

Results include both Hermitian and non-Hermitian short range potentials which are exactly solvable. As illustration, the method is applied to square wells and barriers for which the transmission coefficient is a superposition of Fock-Breit-Wigner distributions. Resonance levels are calculated in the long lifetime limit by means of analytical and numerical approaches. The new complex potentials behave as an optical device which both refracts and absorbs light waves.

description: The derivation of the self-dual relations for the two-form gauge field in the Nambu-bracket description of M5-brane in a constant C-field background initiated in arXiv:0907.4596 is completed by including contributions from all the fields in the M5-brane action. The result is used to examine Seiberg-Witten map of the BPS conditions for the string solitons, up to the first order in the expansion by the parameter $g$ which characterizes the strength of the interactions through the Nambu-bracket.

Methodological and cost comparison of alternative analyses of exploiting Canadian and U.S. frontier natural gas resources
Creators: name: Weisbeck, Don
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this paper is to examine two of the alternatives for transporting natural gas from the Mackenzie Delta-Beaufort Sea area of the Northwest Territories in Canada and from Prudhoe Bay on the Alaska north slope. The first of these is a Mackenzie Valley pipeline proposed by Canadian Arctic Gas Pipeline Ltd to transport both Alaskan and Mackenzie Delta gas to southern markets. The other alternative analysed is the all American El Paso proposal to transport solely Prudhoe Bay gas to U.S. markets. In particular the cost-benefit analyses of these proposals as undertaken by the D.0.I.-Aerospace study and by Helliwell et al., are examined. The paper attempts to highlight differences, both methodological and other, between two studies of the economic returns in exploiting northern natural gas resourses. The Department of the Interior study was undertaken to examine two alternative methods of transporting Prudhoe Bay gas from the Alaskan north slope; a pipeline and liquification route (proposed by El Paso Natural Gas Co.), and transportation via an all pipeline route which would traverse Alaska, the Yukon Territory, and the Northwest Territories, and thence through southern Canada into the continental U.S.A. The major differences highlighted include different estimates of capital and operating costs, for the proposed Mackenzie Valley Pipeline, between D.O.I, and CAGPL. Also evaluated are the different lifetime assumptions, estimates for the supply price of capital and the discount rate, and the treatment of Canadian taxes.
title: Interactions between Rocky Mountain Bighorn Sheep Ovis canadensis canadensis and Domestic Sheep Ovis aries and the Biological, Social, Economic, and Legal Implications of these Interactions on USDA Forest Service Lands in the Evanston/Mt. View Ranger District

description: Strong evidence exists indicating domestic sheep (Ovis aries) can infect Rocky Mountain bighorn sheep (Ovis canadensis canadensis), a United States Forest Service (USFS) Region 4 sensitive species, with pneumonia (Callan 1991; Foreyt 1989, 1992, 1994; Foreyt and Lagerquist 1996; George et al 2008; Wehausen et al. 2011). Since the transmission of the pneumonic bacteria between the domestic and wild sheep is a result of bighorn sheep coming into contact with the bacteria carried in the mucous membranes of the domestic sheep, bighorn sheep at risk of initially contracting the bacteria are those individuals that enter areas currently being grazed or that have been recently grazed by domestic sheep (Foreyt 1990; Jessup 1985; Martin et al. 1996; Monello et al. 2001; Rudolph et al. 2003). The issue is further compounded when infected bighorn sheep return to their herd and have the potential to spread the bacteria to other members, which can result in substantial mortality (Shackleton et al. 1999).
Throughout the western United States (U.S.), the USFS and various state wildlife agencies are struggling to protect and maintain the viability of Rocky Mountain bighorn sheep populations that coexist with domestic sheep being grazed on National Forest lands. This study reviews the biological, social, economic, and legal factors regarding Rocky Mountain bighorn sheep population protection and viability in the presence of domestic sheep, with special attention given to the Evanston/Mt. View Ranger District (EMVRD) on the Uinta-Wasatch-Cache National Forest (UWCNF). Additionally, possible solutions to the problem associated with the comingling of bighorn sheep and domestic sheep and the spread of pneumonia to bighorn sheep were investigated on the EMVRD. This included looking at ways to eliminate interactions between the domestic and wild sheep by identifying movement patterns of six satellite collared bighorn sheep of the Hoop Lake herd on the EMVRD.

title: Field Calibration of the Float Method in Open Channels
Creators: name: Escurra, Jorge
Publisher: name: Utah State University

description: Surface velocity coefficients were calculated at five locations in three different irrigation canals in Logan, Utah. First, the total flow' rate was measured using current meters and calculated cross-sectional flow area. Second , the surface velocity was measured using four trials of the float method , and the average float travel time was calculated for each location and measurement instance. The measurements were taken on different days for various water depths in the canals. Third, the surface and mean cross-sectional velocities were divided , yielding the surface velocity coefficient, for every measurement at each of the five locations. Several channel bed elevations were also measured near each location along a distance of 100 m or more, as necessary, to define the average longitudinal bed slope. Linear equations and averages were developed from the relationship between the velocity ratios and critical depth, and between those ratios and the measured water depths. Finally, the approximate cross-sectional velocity profiles for several of the measurement instances were produced using GIS software.
All the steps mentioned above were followed to determine surface velocity coefficients for use with the float method. The results in the five locations show that the coefficients are not proportional to the water depth variation, and that the presence of rocks and sediment in the channel bed affect the coefficient values. Consequently, the development of a linear relation among coefficients to correct the surface velocity obtained from float method was difficult to obtain from the available data. In the five measurement locations, the surface velocity coefficients vary from 0.33 to 0.81 and the measured water depths during the period of evaluation were from 0.16 m to 0.53 m. No clear relationship was found between average water depth and surface velocity coefficient.
title: Unwritten Law: Resilient Management in Latin American Artisanal Fisheries
Creators: name: Chapman, Brandon
Publisher: name: Utah State University

description: Latin American small-scale fishery production is crucial to local communities that count on fish as a key source of protein in daily consumption and for supplying the increasing demand for exported high-value species in the first world. Many small-scale fishing communities have exhibited various forms of informal institutions that serve to manage rights to the fishery, a common-pool resource (CPR). An emerging theme in the CPR management literature is that there are certain types of institutions that exist in successful informal management contexts. Seven case studies from small-scale fishing communities in Latin America are analyzed in order to determine if these model management institutions are supported. These case studies are then analyzed to determine what accounts for resilient informal management institutions in the face of commercial and outsider encroachment. The thesis is that robust shoreline activities promote reciprocity that allows for rapid collective action in the face of external threats.

description: We theoretically study the polarization entanglement of photons generated by the biexciton cascade in a GaAs/InAs semiconductor quantum dot (QD), located in a nano cavity. A detailed analysis of the complex interplay between photon- and carrier coherences and phonons which occurs during the cascade allows us to clearly identify where the entanglement is generated and destroyed. A quantum state tomography is performed for varying exciton fine structure splittings. By constructing an effective multi-phonon Hamiltonian which couples the continuum of the wetting layer states to the QD we investigate the relaxation of the biexciton and exciton states. This consistently introduces a temperature dependence to the cascade. Considering typical Stranski-Karastanov grown QDs, for temperatures around 80 K the degree of entanglement starts to be affected by the dephasing of the exciton states and is ultimately lost above 120 K.

description: In this paper the regularity of optimal transportation potentials defined on round spheres is investigated. Specifically, this research generalises the calculations done by Loeper, where he showed that the strong (A3) condition of Trudinger and Wang is satisfied on the round sphere, when the cost-function is the geodesic distance squared. In order to generalise Loeper's calculation to a broader class of cost-functions, the (A3) condition is reformulated via a stereographic projection that maps charts of the sphere into Euclidean space. This reformulation subsequently allows one to verify the (A3) condition for any case where the cost-fuction of the associated optimal transportation problem can be expressed as a function of the geodesic distance between points on a round sphere. With this, several examples of such cost-functions are then analysed to see whether or not they satisfy this (A3) condition.

description: Modern cars are evolving in many ways. Technologies such as infotainment systems and companion mobile applications collect a variety of personal data from drivers to enhance the user experience. This paper investigates the extent to which car drivers understand the implications for their privacy, including that car manufacturers must treat that data in compliance with the relevant regulations. It does so by distilling out drivers' concerns on privacy and relating them to their perceptions of trust on car cyber-security. A questionnaire is designed for such purposes to collect answers from a set of 1101 participants, so that the results are statistically relevant. In short, privacy concerns are modest, perhaps because there still is insufficient general awareness on the personal data that are involved, both for in-vehicle treatment and for transmission over the Internet. Trust perceptions on cyber-security are modest too (lower than those on car safety), a surprising contradiction to our research hypothesis that privacy concerns and trust perceptions on car cyber-security are opponent. We interpret this as a clear demand for information and awareness-building campaigns for car drivers, as well as for technical cyber-security and privacy measures that are truly considerate of the human factor.
