title: The Life History of the Dewberry Fruit Worm Cacoecia Rosaceana (Harr.) in Utah
Creators: name: Allen, Merlin W.
Publisher: name: Utah State University
Year: 1937

description: The purpose of this study has been to determine the identity and the life history of certain larvae attacking dewberry fruits and foliage in a few sections of Utah. The dewberry fruit worm as it was called until it was definitely identified the oblique-banded leaf-roller, was first observed by farmers at Granite and Butlerville in 1932. Since 1934 it has been found affecting dewberries in other parts of northern Utah.
This investigation was begun in the spring of 1935 and continued until the fall of 1936, being made possible through the Utah Agricultural Experiment Station, Department of Entomology, and with the cooperation of various farmers in the vicinity of Granite, Utah. Field studies were made at Granite, Butlerville and southeast Pleasant Grove during the course of the investigation. Overwintering studies were carried on at Logan during the winter of 1935-36.
Since this insect is one of the most important pests of dewberries in Utah a careful study of its life history and habits was considered necessary before control methods were undertaken.

description: The color number $N_c$-dependence of the interplay between quark-antiquark condensates $$ and diquark condensates $$ in vacuum in two-flavor four-fermion interaction models is researched. The results show that the $G_S$-$H_S$ (the coupling constant of scalar $(\bar{q}q)^2$-scalar $(qq)^2$ channel) phase diagrams will be qualitatively consistent with the case of $N_c=3$ as $N_c$ varies in 4D Nambu-Jona Lasinio model and 2D Gross-Neveu (GN) model. However, in 3D GN model, the behavior of the $G_S$-$H_P$ (the coupling constant of pseudoscalar $(qq)^2$ channel) phase diagram will obviously depend on $N_c$. The known characteristic that a 3D GN model has not the coexistence phase of the condensates $$ and $$ is proven to appear only in the case of $N_c\leq 4$. In all the models, the regions occupied by the phases containing the diquark condensates $$ in corresponding phase diagrams will gradually decrease as $N_c$ grows up and finally go to zero if $N_c \to \infty$, i.e. in this limit only the pure $$ phase could exist.

description: We study the variation of the trace of the Frobenius endomorphism associated to a cyclic trigonal curve of genus g over a field of q elements as the curve varies in an irreducible component of the moduli space. We show that for q fixed and g increasing, the limiting distribution of the trace of the Frobenius equals the sum of q+1 independent random variables taking the value 0 with probability 2/(q+2) and 1, e^{(2pi i)/3}, e^{(4pi i)/3} each with probability q/(3(q+2)). This extends the work of Kurlberg and Rudnick who considered the same limit for hyperelliptic curves. We also show that when both g and q go to infinity, the normalized trace has a standard complex Gaussian distribution and how to generalize these results to p-fold covers of the projective line.

description: We point out the possibility that the magnitude of the bare gauge coupling constant is determined theoretically in a composite model of all particles in SUSY theories. We show explicitly in two space-time dimensions that the NL/L SUSY relation (i.e., a SUSY compositeness condition for all particles) between N = 2 LSUSY QED and N = 2 NLSUSY determines the magnitude of the bare electromagnetic coupling constant (i.e., the fine structure constant) of N = 2 LSUSY QED.

title: Plant Evolutionary Response to Climate Change: Detecting Adaptation Across Experimental and Natural Precipitation Gradients
Creators: name: Peña, Jacqueline J.
Publisher: name: Utah State University
Year: 2018

description: Global climate change is a real-time problem that presents threats to many species. Climate change can alter ecosystems and may lead to species extinction. Species can respond to climate change by moving to a better environment or adapting. Therefore, it is necessary to rely on several approaches and perspectives to anticipate ecological impacts of climate change. A common strategy uses models to understand how populations respond to different climate scenarios. Ecological models have helped usunderstand population persistence, but they often ignore how populations adapt to environmental stress. Adaptive evolution has been ignored because it was assumed that evolution was too slow to have any effect on ecology. Current research has shown that some populations are able to rapidly adapt to novel environments and this is essential for population persistence. We used a population genomics approach to understand how different precipitation regimes affect the perennial bunchgrass, Pseudoroegneria spicata, in the eastern Idaho sagebrush steppe. Our objective was to determine how genetic diversity changes under manipulated precipitation regimes and whether these changes were consistent with patterns of genetic diversity under natural precipitation regimes. The manipulated precipitation regimes consist of three precipitation treatments: control, drought with 50% ambient precipitation, and irrigation with 150% ambient precipitation. The natural precipitation regimes consist of two treatments: low elevation (drier than the experimental site) and high elevation (wetter). We collected plant tissue to isolate plant DNA and then used sequenced DNA for analyses. We used a hierarchical Bayesian model to estimate genotypes and allele frequencies across all loci. We found that there were low levels of genetic variation across all experimental precipitation treatments. When examining genetic differentiation, we found there was stronger differentiation in the natural precipitation regimes. Our study focuses on the short-term responses to climate to understand how environmental stress influences genetic diversity.

Can mass loss and overshooting prevent the excitation of g-modes in blue supergiants?

description: Thanks to their past history on the main sequence phase, supergiant massive stars develop a convective shell around the helium core. This intermediate convective zone (ICZ) plays an essential role in governing which g-modes are excited. Indeed a strong radiative damping occurs in the high density radiative core but the ICZ acts as a barrier preventing the propagation of some g-modes into the core. These g-modes can thus be excited in supergiant stars by the kappa-mechanism in the superficial layers due to the opacity bump of iron, at log T=5.2. However massive stars are submitted to various complex phenomena such as rotation, magnetic fields, semiconvection, mass loss, overshooting. Each of these phenomena exerts a significant effect on the evolution and some of them could prevent the onset of the convective zone. We develop a numerical method which allows us to select the reflected, thus the potentially excited, modes only. We study different cases in order to show that mass loss and overshooting, in a large enough amount, reduce the extent of the ICZ and are unfavourable to the excitation of g-modes.

title: Cultural Analysis of the Indian Women's Festival of Karvachauth
Creators: name: Sahney, Puja
Publisher: name: Utah State University
Year: 2006

description: The festival of Karvachauth is celebrated by upper class married women of North India and occurs in the month of October or early November. On this day married women fast to ensure the long lives of their husbands. They wake up before dawn and eat a meal. After sunrise they do not drink water or eat any food until they see the moon at night. The moon is watched through a sieve and prayed to before breaking the fast. An important part of Karvachauth is a ritual that is performed by women in the afternoon. This ritual is hosted by a woman of the neighborhood and other women assemble in the house where they form a circle. The narration of a folktale of a princess named Veeravati forms the center of the ritual. Women also dress up in festive bright saris and lots of jewelry for the ritual. Some part of the day is spent in putting intricate designs of henna on their hands and feet.
Although women's act of fasting for their husbands might appear as a sign of subjugation, in my thesis I argue that it is not. Rather, festivals like Karvachauth temporarily liberate women from daily restrictions and give them a licensed freedom to break away from customs that confine them to the threshold of their households. I argue that Karvachauth gives women a chance to move out of their confined private worlds into the public world, dominated by men, and out of their reach in daily life. I do acknowledge that women must satisfy the serious aspects of the ritual first if they wish to enjoy the liberties. But once they are able to do so, the freedoms are easily manipulated by women to empower them, albeit temporarily, in various ways.
title: The Influence of Mechanical Stratigraphy on Thrust-Ramp Nucleation and Propagation of Thrust Faults
Creators: name: Wigginton, Sarah S.
Publisher: name: Utah State University
Year: 2018

description: Our current understanding of thrust fault kinematics predicts that thrust faults nucleate on low angle, weak surfaces before they propagate upward and forms a higher angle ramp. While this classic kinematic and geometric model serves well in some settings, it does not fully consider the observations of footwall deformation beneath some thrust faults. We examine an alternative end-member model of thrust fault formation called “ramp-first” fault formation. This model hypothesizes that in mechanically layered rocks, thrust ramps nucleate in the structurally strong units, and that faults can propagate both upward and downward into weaker units forming folds at both fault tips. To explore this model, we integrate traditional structural geology field methods, two dimensional cross section reconstructions, and finite element modeling. Field data and retro-deformable cross sections suggest that thrust faults at the Ketobe Knob, in Utah nucleated in strong layers and propagated upward and downward creating folds in weak layers. These findings support the hypothesis that thrust faults and associated folds at the Ketobe Knob developed in accordance with the ramp-first kinematic model.We can apply this understanding of the mechanics behind thrust fault nucleation and propagation in mechanically layered stratigraphy to a wide range of geological disciplines like structural geology and tectonics, seismology, and petroleum geology. By incorporating our knowledge of lithology into fault models, geologists are more likely to correctly interpret structures with limited data sets.

description: To evaluate Australian early-career general practitioners’ perceptions of the utility of their prior vocational training in preparing them for independent specialist practice. We hypothesised that in-practice teaching would be perceived as more useful than formal education delivered by Regional Training Organisations (RTOs). A cross-sectional questionnaire-based study of early-career general practitioners (RTO ‘alumni’). The outcomes were Likert scale ratings of alumni’s perceived impact of RTO education versus in-practice training on their preparedness for independent practice. Ratings were compared using Wilcoxon signed-rank tests. Multivariable linear regression was used to establish alumni characteristics associated with perceptions of utility of in-practice versus RTO-delivered education. Three hundred and fifty-four alumni responded (response rate 28%). In-practice training was rated statistically significantly higher than RTO education for minor procedural skills, teaching skills, professional responsibilities, tolerating clinical uncertainty, and preparing for managing child and adolescent health, aged care, chronic disease, multi-morbidity and mental health. RTO education rated higher than in-practice training for practising evidence-based medicine and Aboriginal and Torres Strait Islander health. For a number of further areas, there was no statistically significant difference in alumni ratings of utility. In-practice or RTO-led teaching was perceived as more useful for some components of independent practice, whilst for others there was no significant difference. The findings support recognition of the individual educational components of a blended education/training structure.

title: Identification of Sperm Chromatin Proteins as Candidate Markers of Stallion Fertility
Creators: name: Ketchum, Chelsea C.
Publisher: name: Utah State University
Year: 2018

description: During spermatogenesis, histones are largely replaced by transition proteins and protamines in normal stallions. Incomplete nucleoprotein exchange results in the abnormal retention of histones and transition proteins, which is an indicator of poor sperm quality. Equine nucleoprotein exchange has not previously been investigated in detail, so that equine sperm chromatin quality problems, which are often responsible for poor breeding performance of stallions, are not well understood. In order to characterize chromatin remodeling events in stallion spermatogenesis and to identify proteins indicative of sperm chromatin defects, such as excessive amounts of histones, we identified antibodies that recognize equine testis-specific proteins of interest. Immunoblotting of testis and sperm protein lysates and immunofluorescence staining of histological tissue sections were used to identify candidate marker proteins of incomplete sperm chromatin maturation. Results of the study, which represents the first comprehensive characterization of the nucleoprotein exchange during spermatogenesis in the stallion, challenge the paradigm that the main function of histone H4 lysine (hyper-) acetylation (concomitant H4K5 and H4K8 acetylation) is to facilitate nucleosome ejection during spermatid nuclear elongation to allow for transition protein and protamine insertion into the chromatin.
That paradigm was based on observations in mice and rats where H4 acetylation in several lysine residues occurs just prior to or during nuclear elongation. In contrast, the equine data presented here show strong acetylation of H4 in K5, K8 and K12 positions immediately after meiosis in round spermatids, independent of nuclear transition protein 1 deposition. Furthermore, results of H4K16 acetylation analyses underline the importance of this mark, which is likely mediated by DNA damage signaling pathways, emphasizing the importance of DNA repair processes for the exchange of nucleoprotein exchange in spermiogenesis and therefore, in extension, for male fertility. In addition, a revised description of the equine spermatogenic cycle is proposed here that is better aligned with human, mouse and rat spermatogenesis. Finally, the testis-specific histone variant TH2B was identified as a potential quantitative marker of equine sperm quality.
The impact of computer networking developments on computer based information systems, user organizations and their management
Creators: name: Stevenson, David Lyle
Publisher: name: University of British Columbia
Year: 2010

description: In the past few years, the technical and economic feasibility of computer networks has been demonstrated. This cost effectiveness has resulted ln a rapid growth in the demand for computer network services. Thus, a number of organizations are developing computer networking offerings ranging from the supply of data communications links, which allow organizations to network their own computer centers, to the supply of access to the resources of fully developed computer networks. These developments are having considerable impact upon the task of designing and implementing computer based information systems (CBIS) for user organizations, as well as upon the management of such systems. Furthermore, there are wider implications for the user organizations and their management, in terms of information flows and management structures within the organization. This thesis surveys and examines the network developments, and considers the potential impacts on, and implications for both the CBIS, its development and management, and the organization and its management. There are three main sections in the thesis. The first is an introduction to computer networks and their development, including a survey of the relevant technologies and techniques, a number of examples of existing networks and their user organizations, and an analysis of the economics of networking as experienced by these organizations. The second section considers some of the potential impacts of networking developments on contemporary information system design, implementation, and management, including hardware and software resource considerations, as well as the implications for information system management of participation in a network. The third section analyzes some of the impacts of computer networking developments and participation on the user organizations in terms of the effects on information flows in the organization, and the resulting Impacts on operating structure and functions. This section also outlines some of the opportunities and challenges which face network user organizations and their management.
title: The Journey of Education: Characteristics of Shoshone-Bannock High School and Community Members on the Fort Hall Indian Reservation
Creators: name: Galindo, Ed
Publisher: name: Utah State University
Year: 2003

description: This dissertation examined personal, cultural, school, and family factors that contribute to the decision of Native American students to remain in school until graduation or to drop out. One hundred eighty-one participants who had either graduated or dropped out of school completed a 140-item questionnaire. Participants lived on the Shoshone-Bannock Indian Reservation located at Fort Hall, Idaho.
Factors examined in the survey instrument included substance abuse by self or family members, peer pressure, trouble with the law, self-esteem, teen pregnancy, family structure, socioeconomic status, parents education, academic achievement, teacher attitudes and expectations, school attendance, tribal self-identity and pride, and bilingualism. This research was based on the assumption that issues and processes in Native American education must be addressed by Native people themselves in order for positive change to occur. In addition, the research looked for factors that seem to keep Native Americans in school.
The analysis suggested that respondents who were at a higher risk of dropping out of school had a negative self-attitude, frequently skipped school, and had negative attitudes about their teachers' expectations. These results differed significantly from those of Native Americans who had positive self-attitudes, positive attitudes about their teachers' expectations, and positive family influences. Themes of poverty, self-esteem, and teacher attitudes repeatedly surfaced. Graduates frequently reported that positive family expectations (including teachers) kept them in school.
This dissertation provides important information for those involved in Native American education. In addition, this dissertation brings together the views of the Native American, specifically the Shoshone-Bannock people, in the journey of education. Together, the review of literature and data collected on the Shoshone-Bannock Indian reservation provide a valuable resource for teachers, parents , and community members now involved, or soon to be involved, in Native American education.

description: Powerful radio-AGN are hosted by massive elliptical galaxies which are usually very poor in molecular gas. Nevertheless gas is needed in the very center to feed the nuclear activity. We aim to study the molecular gas properties (mass, kinematics, distribution, origin) in such objects, and to compare them with results of other known samples. We have performed at the IRAM-30m telescope a survey of the CO(1-0) and CO(2-1) emission in the most powerful radio galaxies of the Local Universe, selected only on the basis of their radio continuum fluxes. The main result of our survey is the very low content in molecular gas of such galaxies compared to spiral or FIR-selected galaxies. The median value of the molecular gas mass, including detections and upper limits, is 2.2x10^8 Msun. If separated into FR-I and FR-II types, a difference in H_2 masses between them is found. The median value of FR-I galaxies is about 1.9x10^8 and higher for FR-II galaxies, about 4.5x10^8 Msun but this is very probably entirely due to a Malmquist bias. Our results contrast with previous surveys, mainly selected through the FIR emission, implying larger observed masses of molecular gas. Moreover, the shape of CO spectra suggest the presence of a central molecular gas disk in 30% of these radio galaxies, a lower rate than in other active galaxy samples.

description: The research sought to examine the impact of resilience building interventions toward rural livelihoods in Mberengwa and Zvishavane Districts. In this research, a mixed method research design was adopted to enhance the quality, complementarity, and expansion of results. Data were gathered using questionnaires, interviews and field observations. Questionnaires were distributed to 200 household heads in Mberengwa and 120 households selected in Zvishavane Districts using convenience sampling technique. Key informants interviewed included Lutheran Development Services representative, Rural District Council representative, District Crop and Livestock Officer (DCLO). The acquired qualitative data were subjected to content analysis while quantitative data was analyzed using SPSS version 23.0. The study findings show that Villages Savings and Lending, water harvesting, community horticultural gardens, apiculture, climate smart agriculture were some of the initiatives contributing to resilience building. These resilience building interventions contributed toward the attainment of Sustainable Development Goals 1; ending hunger, 2; zero hunger; and 13 climate action. The study recommends that the government, through the relevant ministry should ensure resilience building initiatives are included in their five-year plan, so that they have adequate and realistic implementation time frames.

Creators: name: Finnie, John I.
Publisher: name: Utah State University
Year: 1987

description: Finite Element computer codes in two and three dimensions were written that solve both laminar and turbulent flow. These codes use the two equation (k and E) turbulence model to evaluate turbulent viscosity. They were tested with 29 different flow problems. The largest two dimensional turbulent problem solved is flow under a sluice gate. A three dimensional vortex flow problem was attempted but was not feasible due to the size of the available computer. The Harwell sparse matrix subroutines of the United Kingdom Atomic Energy Authority were used to solve the set of simultaneous equations. The performance of these subroutines is evaluated. The importance of defining adequate finite element grids and setting proper boundary and initial conditions is discussed.

description: We report the detection of a black hole (NGC 1850 BH1) in the $\sim$100 Myr-old massive cluster NGC~1850 in the Large Magellanic Cloud. It is in a binary system with a main-sequence turn-off star (4.9 $\pm$ 0.4 M${_\odot}$), which is starting to fill its Roche Lobe and becoming distorted. Using 17 epochs of VLT/MUSE observations we detected radial velocity variations exceeding 300 km/s associated to the target star, linked to the ellipsoidal variations measured by OGLE-IV in the optical bands. Under the assumption of a semi-detached system, the simultaneous modelling of radial velocity and light curves constraints the orbital inclination of the binary to ($38 \pm 2$)$^{\circ}$, resulting in a true mass of the unseen companion of $11.1_{-2.4}^{+2.1}$ $M_{\odot}$. This represents the first direct dynamical detection of a black hole in a young massive cluster, opening up the possibility of studying the initial mass function and the early dynamical evolution of such compact objects in high-density environments.

description: Changes in the amount of water and sediment that enter a river can change its shape and size. The way that rivers change is affected by a variety of factors, including the size of the sediment in the river, and past changes to the river. The Diamond Fork River in central Utah has been altered by water deliveredfromthe Colorado River system for over a century. Beginning in 1915, water used for irrigation was delivered through a tributary, Sixth Water Creek, with daily summer flows that were much larger than natural flows. This caused drastic change to the rivers, as they became wider and vegetation along the channel margin and floodplain was destroyed. Management changes in 1997 and 2004 reduced the amount of water and sediment added to the river. In this study, we sought to understand how Sixth Water and Diamond Fork changed in the past and what the implications are for the future.
We used data from a variety of sources to describe how and why the river changed in the past. Our results indicate that parts of the river that are not confined by valley walls became very wide during the period of elevated flows and narrowed after the change in management in 1997. Confined reaches experienced minor changes over the period of record. Areas of the channel that were most dynamic in the past are the most susceptible to future change because they have finer sediment that is more easily erodible. Areas that did not experience past changes are unlikely to change in the future without direct intervention from humans or beaver. The findings of this study improve our understanding of Sixth Water and Diamond Fork, and confirm the importance of past changes and valley confinement.
title: Organic Matter Sources, Composition, and Quality in Rivers and Experimental Streams

description: Organic matter (OM) is often considered the “currency” for ecosystem processes, such as respiration and primary production. OM in aquatic ecosystems is derived from multiple sources, and is a complex mixture of thousands of different chemical constituents. Therefore, it is difficult to identify all the sources of OM that enter and exit aquatic ecosystems. As humans develop undisturbed land, the rate at which terrestrial OM (e.g.soil and plants) and associated nutrients (e.g.nitrogen) enters rivers has increased. Increased nutrients may lead to increased primary production from aquatic plants and algae, potentially causing eutrophication and harmful algal blooms. In this study, I identified and characterized different sources of OM in four watersheds of Northeastern Utah with multiple land covers such as cities, forests, and crops. I expected OM in watersheds with human-altered land cover would have more OM produced instream by algae and other primary producers, than OM in less disturbed watersheds, which typically have OM from terrestrial sources. I found that OM at river sites with high human impact had high amounts of OM from instream primary production, but there was also OM produced in-steam at sites with low human impact. The greatest differences in OM across watersheds was due to wastewater treatment effluent. I also measured microbial consumption rates of algal derived and terrestrially derived DOM in experimental streams to quantify how much faster algal derived OM was consumed than terrestrial OM. I found algal derived OM was consumed extremely fast, so fast that realistic measurements of its consumption in some river ecosystems may not be possible. It is important to identify and characterize sources of OM to rivers, so watershed manager scan devise effective OM reduction plans appropriate for the constituent of concern unique to that watershed or region. Constituents of concern associated with OM include pathogens affiliated with manure, toxins in harmful algal blooms, metals, and pharmaceuticals from wastewater treatment effluent. Each pollutant requires a unique mitigation strategy and therefore the first step to pollution mitigation is source identification.

description: The Sars-CoV-2 virus and the related public health measures have triggered a break in everyday life. Despite growing global protest movements against these health measures, ‘solidarity’ was called for by civil society groups, affected businesses, and politicians as an intuitive mode of action in this crisis. Writing from Germany, we explore how in the midst of the Covid-19 crisis a specific discourse of solidarity and locality blossomed; namely a call to solidarity-based consumption. Using documentary photography, we discuss the shifts in the attribution of meaning and discourses through which consumption has been framed by small-shop owners in Linden, Hannover, Germany. In the paper, we explore the local geographies of boycotting and specifically the ways calls for boycotting are articulated by shop owners in the neighbourhood. We find that these calls became entangled with a specific neighbourhood identity. Through our photographic documentation we also find that purchases at local stores are now framed as a necessary act of local support. Finally, we reflect on the limitations of consumption as a strategy to overcome crisis and express solidarity.
Supersonic Expansion of the Bipolar Hii Region Sh2-106: A 3,500 Year-Old Explosion?

description: Multi-epoch narrow-band HST images of the bipolar Hii region Sh2-106 reveal highly supersonic nebular proper motions which increase with projected distance from the massive young stellar object S106~IR, reaching over ~30 mas/year (~150 km/s at D=1.09 kpc) at a projected separation of ~1.4' (0.44 pc) from S106~IR. We propose that S106~IR experienced a $\sim10^{47}$ erg explosion ~3,500 years ago. The explosion may be the result of a major accretion burst, a recent encounter with another star, or a consequence of the interaction of a companion with the bloated photosphere of S106~IR as it grew from ~10 through ~15 Solar masses at a high accretion rate. Near-IR images reveal fingers of molecular hydrogen emission pointing away from S106~IR and an asymmetric photon-dominated region surrounding the ionized nebula. Radio continuum and Brackett-gamma emission reveal a C-shaped bend in the plasma, either indicating motion of S106~IR toward the east, or deflection of plasma toward the west by the surrounding cloud. The Hii region bends around a ~1' diameter dark bay west of S106~IR that may be shielded from direct illumination by a dense molecular clump. Herbig-Haro (HH) and Molecular Hydrogen Objects (MHOs) tracing outflows powered by stars in the Sh2-106 proto-cluster such as the Class 0 source S106 FIR are discussed.

description: Abstract

The current problem in the building sector is the excessive use of water in the curing process of concrete, leading to water scarcity issues and higher operational costs. The traditional methods of curing concrete such as water curing, are time-consuming and require extensive labor. Additionally, the production of cement for construction purposes makes a significant quantity of carbon dioxide released, contributing to environmental degradation. The Pakistan is facing potable water scarcity issues especially for the construction industry. To address these challenges, there is a need to explore alternative self-curing methods that can reduce water consumption. This method partially replaces cement with self-curing agents, reducing evaporation and moisture, thus preventing water scarcity and promoting future industry growth. This study has a restricted scope to the M20 Grade in which the research is focused on examining the efficacy of polyethylene Glycol (PEG) 400 and 6000 as a substance that cures itself use with varying percentage such as 1.5%, 2% and 2.4%. The timeframe for testing the efficacy of self-curing with PEG is set at 7 to 28 days.  Finally, the research has revealed that with the addition of PEG 400 and PEG 6000 in the concrete mixing have significant effect on the compressive strength, split tensile strength and water absorption capacity of the mixed concrete.

description: The purpose of this study was to examine the changing relationship between the National Park Service and the residents of Wayne County, Utah. In 1937, Capitol Reef National Park was created as a result of the efforts made by local residents looking for a solution to their economic problems. Over the next five decades, the anticipated economic upturn spurred by the National Park did not develop. Instead, the relationship between the parties involved underwent a radical change because of conflicts over private landholdings, grazing and mineral rights, expansion, development, and road building. While this study does trace the growth of Capitol Reef into a national park, it is not an administrative history of the site. Its focus is on failure of the Park to live up to the expectations of its early supporters and the resulting deterioration of the relationship between local residents and the National Park Service.
