title: Groundwater and Surface Water Contributions to Metals Loading in Bayhorse Creek at the Abandoned Ramshorn Mine Site Near Bayhorse, Idaho
Creators: name: McDonough, Hannah L.
Publisher: name: Utah State University
Year: 2015

description: Many abandoned mines in the United States are littered with waste metals that leach into watersheds and degrade habitats. Although metals-laden waters may appear pristine, fish bioaccumulate high concentrations of metals in their tissues, which create health risks if consumed by humans. This study examines the source and fate of metals in Bayhorse Creek near the abandoned Ramshorn mine outside of Challis, Idaho. In 2003, the U.S. Geological Survey found high levels of arsenic, cadmium, chromium, copper, lead, silver, and zinc in soils adjacent to the tailings pile. The Idaho Department of Environmental Quality authorized remediation to begin in summer 2011 without fully comprehending the source and fate of contaminants into the creek.
Metals loads were determined along the reach of Bayhorse Creek adjacent to the mine by measuring the flow rates of streams and groundwater seeps, and collecting water samples for chemical analysis. The chemical controls on metals mobility and attenuation in the surface and groundwater at the site were determined by computer modeling, a diffuse double-layer surface complexation model and the geochemical program PHREEQC.
Dissolved and suspended arsenic, copper, iron, manganese, lead, and zinc load the creek. The lowest site along the creek consistently measured as the highest load. Arsenic, copper, and lead loads were relatively insignificant compared to iron and manganese. The results indicate that 47% or more of the iron and manganese travel as metal-oxides, and arsenic and zinc tend to sorb to ferrous oxides. Large metals fluxes between SW-1 and SW-5 and at SW-8 suggest tailings and waste rock located between SW-1 and SW-5 and the slag pile adjacent to SW-8 are the main sources of metals contamination. Concentrations below the EPA drinking water standards and the absence of acidic pH indicate that the main metals loading consists of safe levels of iron, manganese, and zinc.

description: CEO compensation is a highly controversial subject. While most company directors believe that CEO pay is not a problem, the majority of the American public believes that it is. The difficulties that boards face in justifying CEO pay levels in some ways stem from the challenge of quantifying how much value a CEO creates and how much of this value should be shared as compensation. We examine this topic in detail and ask: Why are CEO compensation arrangements not explicitly tied to value creation? How much does a CEO personally contribute to corporate performance? How is corporate performance best measured: by change in stock price or change in corporate profits? What portion of shareholder value creation should a CEO receive in pay? Why don’t companies explicitly calculate and disclose the relation between value creation and pay?
An asymptotic preserving approach for nonlinear Schrodinger equation in the semiclassical limit

description: We study numerically the semiclassical limit for the nonlinear Schroedinger equation thanks to a modification of the Madelung transform due to E.Grenier. This approach is naturally asymptotic preserving, and allows for the presence of vacuum. Even if the mesh size and the time step do not depend on the Planck constant, we recover the position and current densities in the semiclassical limit, with a numerical rate of convergence in accordance with the theoretical results, before shocks appear in the limiting Euler equation. By using simple projections, the mass and the momentum of the solution are well preserved by the numerical scheme, while the variation of the energy is not negligible numerically. Experiments suggest that beyond the critical time for the Euler equation, Grenier's approach yields smooth but highly oscillatory terms.

Year: 2016

description: The litmus test for an effective compensation program is whether it provides “pay for performance.” While the concept of pay for performance is simple, its implementation is not. In particular, boards must consider not only whether a compensation plan encourages executives to pursue corporate objectives and build shareholder value but also the unintended consequences of pay. We consider these issues through the example of Valeant Pharmaceuticals, whose CEO received a compensation package that offered exponential rewards for exceptional long-term performance. We ask: How can shareholders tell whether the right balance has been struck between “pay for performance” and risk? To what extent were the problems that occurred at Valeant directly a result of the incentives placed on its CEO? Would they have occurred if the incentives were less aggressive? Did the board fail to identify red flags that should have warned them that the company’s approach was not sustainable? Did a rising share price make them complacent in their oversight?
title: Growth Performance, Ruminal Fermentation Characteristics, and Economic Returns of Growing Beef Steers Fed Brown Midrib, Corn, Silage-Based Diet
Creators: name: Saunders, Christopher Scott

description: In the beef cattle industry, sustainable beef production is a primary focus, as it has direct effects on environmental stewardship, farm profitability, and public concerns. Research has been and is continually being conducted to evaluate alternative forages such as Brown Midrib Corn Silage (BMRCS) as a major component in growing beef cattle diets, to improve animal performance, ruminal fermentation, and economic returns. The objective of this study was to determine growth performance, ruminal fermentation characteristics, and economic returns of growing beef steers when fed a brown midrib corn silage-based TMR (BMRT) compared with a conventional corn silage-based TMR (CCST). This growing beef study was performed in a completely randomized design with 24 Angus crossbred steers (initial body weight (BW) = 258 ± 23.2 kg) to test 2 treatments: CCST vs. BMRT. All animals were placed in individual pens, and 12 animals allocated to each treatment (n = 12). All steers were adapted to the CCST for a 2-wk period prior to start of the trial. The CCST contained 48.1% CCS whereas the BMRT consisted of 49.0% BMRCS on a dry matter (DM) basis. All steers were fed once per day, and feed bunks assesed each afternoon and prior to morning feeding, which was used to determine the amount of feed to deliver to each pen the following day. The experiment lasted 84 d. For all steers, BW and ruminal fermentation characteristics were measured on wk 4, 8, and 12. Intake of DM averaged 9.54 kg/d across the treatments and was similar between the treatments. Steers fed the BMRT tended to increase average daily gain (ADG) compared to those fed the CCST (1.54 vs. 1.42 kg/d; P = 0.09). In addition, feeding the BMRT tended to increase G:F compared with the CCST (0.165 vs. 0.146; P = 0.07). Feeding the BMRT decreased ruminal pH (6.42 vs. 6.67; P < 0.01), whereas it increased total VFA concentration (P = 0.01) compared with the CCST. Feeding the BMRT decreased molar proportion of acetate (P < 0.01), but increased propionate proportion (P = 0.01), resulting in decreased acetate-to-propionate ratio compared with the CCST (P < 0.02). Steers fed BMRT increased feed margin (P = 0.05) and net return (P = 0.02) compared to those fed CCST throughout the trial. Overall data in this study indicate that feeding the BMRT to growing beef steers enhanced ruminal fermentation and beneficially shifted VFA profiles, which contributed to improved growth performance and economic performance of steers fed the BMRT.

In this way we give an affirmative answer to a forty years old problem posed by Sweedler. On the route the coequalizers and the coproducts in the category of Hopf algebras are explicitly described.

Romain Rolland et L'Heroisme: une Perspective Musicale (Romain Rolland and Heroism: A Musical Perspective)
Creators: name: Yeoland, RH
Publisher: name: University Of Tasmania
Year: 2023

description: The importance of heroism in the life of Romain Rolland, French author, historian and musicologist has previously been investigated as has been his love of music. The fact that Rolland preferred composers he considered heroic such as Beethoven and Handel led the author of this thesis to believe that there may be a link, as yet unexplored, between Rolland's formulation of heroism and music. The aim of this thesis is to demonstrate that musical influences and the life of certain composers played a central role in the fashioning of Rolland's concept of heroism. The first chapter, Rolland's musical formation covers the formative years of Rolland's life, outlining the development of his musical taste and also his interest in heroism. The influence of his mentor, Malwida von Meysenbug is examined, as is his search for a role model heroic figure. Beethoven, the second chapter, discusses the influence of this composer in Rolland's life and enumerates the musician's heroic qualities which Rolland adapts for the formulation of his own fictional hero. The biography The Life of Beethoven written by the author is also examined. The third chapter, Other heroic musicians investigates Rolland's musicological works in order to highlight heroic qualities found in other composers admired by Rolland. In his most famous work Jean-Christophe, Rolland creates his own heroic figure based on characteristics gleaned from his study of musicians. The character of his protagonist is examined in detail in the fourth chapter, Jean-Christophe. Many composers are criticised by the author for lacking an heroic nature. In order to develop fully the concept of Rolland's hero, a close examination of these 'non-heroic' composers is made in the fifth chapter, The insincerity of musicians. So inspired was Rolland by Beethoven that in writing Jean-Christophe, the author endeavoured to write his own literary 'Heroic Symphony'. The sixth chapter, Rolland's heroic symphony investigates how the author 'musically' structured his novel. The final chapter, Romain Rolland, the hero-prophet discusses how Rolland absorbed many of the heroic qualities that he read about, believing that it was his mission to lead an heroic life and to write inspirational works for his readers.

description: Reservoir characterization becomes challenging in deepwater depositional systems where high exploration costs and complicated geological structures often limit data collection. Rule-based geostatistical subsurface modeling can overcome this data-gap challenge and produce geological representations for these reservoirs using geological rules constrained by even sparse data sets. The rule-based model simulates sediment dynamics through depositional rules in generating reservoir architecture and the associated rock properties distributions. As a result, rule-based models integrate conceptual information, including temporal deposition sequence and consequent compensational stacking patterns. However, selecting realistic rule parameters (e.g., stacking patterns and geometry of depositional elements) and integrating quantitative data (e.g., well logs and fluid production history) remain as obstacles to the broad application of rule-based subsurface models. In this research, I develop a robust rule-based modeling method for deepwater reservoir and machine learning-assisted data conditioning methods for various data (i.e., well data, stratigraphy, and production history) in the rule-based models. In this regard, I study the following subjects: (1) investigation of the realistic rule-parameters and removal of the numerical artifacts by comparing the models with geological observation, (2) solution to the long-standing conditioning challenge of rule-based models through the novel application of machine learning approach, and (3) examination of machine learning applications for a superior model inference model in standard geostatistical methods. The developed workflow enables reservoir characterization in deepwater reservoirs by reproducing their realistic geological heterogeneity and integrating various observed data into the models, resulting in accurate production forecasts. Moreover, the flexibility of the workflow can broaden its applications to different depositional settings, such as fluvial or deltaic reservoirs.

description: Many experiments in quantum information aim at creating multi-partite entangled states. Quantifying the amount of entanglement that was actually generated can, in principle, be accomplished using full-state tomography. This method requires the determination of a parameter set that is growing exponentially with the number of qubits and becomes infeasible even for moderate numbers of particles. Non-trivial bounds on experimentally prepared entanglement can however be obtained from partial information on the density matrix. The fundamental question that needs to be addressed in this context is then formulated as: What is the entanglement content of the least entangled quantum state that is compatible with the available measurement data? We formulate the problem mathematically employing methods from the theory of semi-definite programming and then address this problem for the case, where the goal of the experiment is the creation of graph states. The observables that we consider are the generators of the stabilizer group, thus the number of measurement settings grows only linearly in the number of qubits. We provide analytical solutions as well as numerical methods that may be applied directly to experiments, and compare the obtained bounds with results from full-state tomography for simulated data.

description: Crude oil spills have well-documented, deleterious impacts on the hydrosphere. In addition to macroscopic effects on wildlife and waterscapes, several classes of petroleum derived compounds, such as naphthenic acids (NAs) and polycyclic aromatic hydrocarbons (PAHs), may be released into the water and present aquatic contamination hazards. The concentrations of these contaminants may be affected by both oil type and water chemistry. We characterize the concentrations of NAs and PAHs in natural and constructed waters, spanning a range of pH and salinity, and directly compare the influence of diluted bitumen (DB) and conventional crude (CC) oil, using condensed-phase membrane introduction mass spectrometry (CP-MIMS) as a direct sampling, on-line technique. The concentration and isomer class profiles of classical NAs in the aqueous phase were assessed using electrospray ionization in negative-ion mode as [M-H]− whereas PAH concentrations were monitored using liquid electron ionization (LEI) in positive-ion mode as [M+•]. NA concentrations (0.03–25 ppm) were highly pH-dependent, and an order of magnitude greater in water samples contaminated with DB than CC. Conversely, concentrations of naphthalene (10–130 ppb) and alkyl-naphthalenes (10–90 ppb) were three to four-fold higher in water samples exposed to CC. We demonstrate that naturally occurring dissolved organic matter does not bias results from the membrane sampling approach employed, and that DB and CC contaminated waters can be differentiated using principal component analysis of the NA isomer class distribution in both constructed and natural waters. Finally, we describe the first demonstration of the concurrent analysis of trace NAs and PAHs in the same water sample by controlling perm-selectivity at the membrane and the ionization mode of the mass spectrometer. The techniques employed here for trace analysis of petroleum derived compounds in water can be applied to rapid screening and real-time monitoring of contamination and remediation processes.
The evolution of knowledge
Creators: name: Hoerr, W
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis will argue that there exists a unit of cultural knowledge (the meme) that is analogous to the gene of biological evolution. Genetic knowledge has been gained through the interaction of ancestral organisms with their environments. Those organisms with inferior genetic knowledge have died out. Cultural knowledge has also been gained through the interaction of new ideas within minds. Inferior cultural knowledge has died out. Genes, through their phenotypes, evolve in a physical environment while memes, through their phenotype, thought, evolve in a mental environment. Both vary in their respective environments, and the differential survival of these variations represents a single process underlying gene and meme multiplication. Because the units of knowledge, genes and memes, operate in distincively different environments, and so manifest themselves in different ways, there appear to some people to be two distinctive processes operating. One task of this thesis will be to establish logically this single process. I will show that memes are living units inhabiting a sea of minds in which they compete for survival just as organisms compete for their survival in their physical environment. In using the 'meme' I am not assuming any new physical forces, rather, the meme is a different way of seeing an old problem; cultural evolution. Through this view, contemporary problems can be seen in a new light, and in many cases, better explanations found for them.

description: In this paper we establish a complete local theory for the energy-critical nonlinear wave equation (NLW) in high dimensions ${\mathbb R} \times {\mathbb R}^d$ with $d \geq 6$. We prove the stability of solutions under the weak condition that the perturbation of the linear flow is small in certain space-time norms. As a by-product of our stability analysis, we also prove local well-posedness of solutions for which we only assume the smallness of the linear evolution. These results provide essential technical tools that can be applied towards obtaining the extension to high dimensions of the analysis of Kenig and Merle \cite{keme06} of the dynamics of the focusing (NLW) below the energy threshold. By employing refined paraproduct estimates we also prove unconditional uniqueness of solutions for $d\ge 5$ in the natural energy class. This extends an earlier result by Furioli, Planchon and Terraneo \cite{FPT03} in dimension $d=4$.

Creators: name: Ward, Sherissa A.
Publisher: name: Utah State University
Year: 2015

description: In this thesis the effect of mechanical stimuli on A549 lung cancer cells is studied. Modifications of polydimethylsiloxane (PDMS) surfaces are employed to alter the mechanical stimuli applied to the cells. Flat substrates are first studied and then micropillared substrates are designed, fabricated, and tested as a method to alter the mechanical properties of the PDMS surfaces.
Molds with micro-pillars are designed then fabricated from silicon using deep reactive ion etching. From these molds, a negative then a positive replicate is made using PDMS. The pillared PDMS substrates are fabricated in 10 geometries and used for experiments. A549 cells are cultured on these surfaces then analyzed using fluorescence microscopy and atomic force microscopy (AFM). Fluorescence microscopy images processed by ImageJ software measure the cell spreading area (m2) while AFM quantifies the cell stiffness (kPa).
For flat substrates, the cell stiffness and spreading area increase with increasing substrate stiffness. Further, results on pillared substrates show a similar trend based on pillar geometry changes. For pillared substrates, the A549 cell stiffness and spreading area increase as the height decreases, yet there is decreased cell stiffness and spreading area as the diameter and spacing decreases. The experiments show that changes in surface properties and only mechanical stimuli alter cellular morphology and biomechanics

We find that constraining appropriately the mass function it is possible to obtain a solution of the problem in terms of the hypergeometric function. The mass function for which this turns out to be possible is continuous. In particular we study the scattering problem and derive exact expressions for the reflection and transmission coefficients which are compared to those of the constant mass case. For the very same mass function the bound state problem is also solved, providing a transcendental equation for the energy eigenvalues which is solved numerically.

description: We give general arguments that any interacting non--conformal {\it classical} field theory in de Sitter space leads to the possibility of constructing a perpetuum mobile. The arguments are based on the observation that massive free falling particles can radiate other massive particles on the classical level as seen by the free falling observer. The intensity of the radiation process is non-zero even for particles with any finite mass, i.e. with a wavelength which is within the causal domain. Hence, we conclude that either de Sitter space can not exist eternally or that one can build a perpetuum mobile.

Situation of Dominican political thought and activities in France and England
Creators: name: Brill, Barrie Alfred
Publisher: name: University of British Columbia
Year: 2011

description: This thesis investigates the political thought and activities of the French and English Dominicans. It began historically with a question concerning the nature of the work of John of Paris. Can his De potestate regia et papali be described as a fundamentally theological and philosophical exposition? Such a description would seem to imply a partial separation from the political situation in which he wrote and would see his treatise in relation to the vast mass of the theological literature of the day. In order to test this it would be sensible to undertake a comparative study and to try to see the situation of John of Paris and other Dominicans to discern the effects of this situation on their thought. To understand the major issues of medieval political thought, the preliminary chapter gives a brief account of the development of this thought. The influence which the Order of Preachers exerted on its members cannot be neglected. The heart of this thesis is found in two rather lengthy chapters dealing with the thought and activities of the members of the Dominican Order in both France and England. The result of this examination placed the political writings of the Dominicans in France -- of which John of Paris is the major example--in a position apart from that of their other theological and philosophical works. In England, the philosophical and theological productions of the Dominicans are similar to those which were produced by the Dominicans in France except in one major respect, that of treatises dealing with political thought. The conclusion of this thesis is that the total situation in which these men found themselves must be taken into account in any attempt to understand their thought. In view of this it is evident that Leclercq's view must be modified to the extent that the political situation in which John of Paris wrote explains in part the fact that he wrote a treatise dealing with political affairs. The De potestate regia et papali cannot be regarded merely as a theological and philosophical exposition comme les autres.

description: Greater sage-grouse (Centrocercus urophasianus) populations have declined throughout the western United States over the past 3 decades. Habitat loss within the sagebrush steppe ecosystem is a major factor leading to sage-grouse population decline. Hen sage-grouse were captured, marked, and tracked during the summer of 2012 in southwestern and south-central Wyoming. I performed vegetation surveys, and avian point counts were performed at 1 early-season brood location, 1 late-season brood location, and an accompanying random location for each marked hen regardless of reproductive status. Multinomial models were run to determine what habitat variables were most informative in predicting site selection by hen sage-grouse. During early-brood season, hen sage-grouse with chicks selected sites that had high total shrub cover density; these areas also exhibited high densities of American kestrels (Falco sparverius). They did not avoid areas with common ravens (Corvus corax). Hen sage-grouse not accompanied by a brood selected sites with high total shrub cover and low densities of common ravens and American kestrels. During late-brood season, hen sage-grouse that
were accompanied by a brood selected sites with high shrub cover and low densities of small avian predators, such as black-billed magpies (Pica hudsonia) and American kestrels as well as medium-sized predators, such as common ravens, buteo hawks (Buteo spp.), and northern harriers (Circus cyaneus). Hens that were not accompanied by broods were more often found in sites with high total shrub cover and low densities of small avian predators, but selected sites with higher densities of medium-sized predators. Hen sage-grouse select areas with high total shrub cover during early and late-brood season regardless of their reproductive status. By avoiding predators and selecting areas with cover, hens with broods can reduce the risk of their chicks being depredated.

Progesterone levels indicative of luteal development were present only in the breeding season. Progesterone levels during the seasonal anestrous and postpartum periods were 0.65 ± 0.03 and 0.3 ± 0.02 ng/ml, respectively, and significantly different (P
title: Economic Impacts of Water Conservation Measures in Agriculture and Energy Within the Upper Colorado River Basin
Creators: name: Franklin, Douglas R.
Publisher: name: Utah State University
Year: 1982

description: The demand for water is increasing in the western United States. Coupled with growing emphasis on development of the western resources, the limited supply of water will create an expanding competitive market for water by agricultural, energy, industrial and municipal users. The Upper Colorado River Basin is faced with a question of what water conservation measures in the agricultural and energy sectors can be instigated without reducing agricultural output. If the decision is made to adopt water conservation technology measures, this study addresses the impacts in the private and public investment sectors under alternative public policies, i.e., regulation or non-regulation of salinity, to invest or not to invest in water conservation measures such as evaporation suppression and phreatophyte control, and to invest or not to invest in salinity control projects.
A linear programming model was developed to determine the optimal allocation of water between agriculture and energy as well as the trade off associated with the various policy alternatives of the public sector. The agricultural sector incorporated consumptive use of crops and various irrigation systems. The energy sector incorporated consumptive use of various water conservation technologies and production capacities.

description: 2,4-D-specific IgE antibodies were detected in serum of BALB/c mice using the rat passive cutaneous anaphylaxis (PCA) test following the second intraperitoneal immunization with 1, 10, or 100 ug of 2,4-D0keyhole limpet hemocyanin (KLH) conjugate administered with aluminum hydroxide adjuvant. The groups that received 1 ug of 2,4-D conjugate had the highest antibody titers (geometric mean of 60). A paper radioallergosorbent test (PRAST) was developed for determination of 2,4-D-specific IgE. The PRAST was equally as sensitive as and showed a positive correlation with the PCA assay.
The anhydride of the diacid metabolite of malathion (MMA) coupled to KLH elicited MMA-specific IgE following secondary immunization with 10 and 100 ug and tertiary immunizations with 1, 10, and 100 ug of conjugate. The highest PCA titers (geometric means of 208 and 195) were found after three immunizations with 10 or 100 ug of conjugate, respectively. A PRAST for MMA-specific IgE was developed and yielded results equivelant to those obtained using the PCA procedure.
Concurrently with these studies, dinitrophenyl-specific IgE elicited with 1 ug of dinitrophenyl-KLH conjugate was measured by the PCA test at all intervals examined.
2,4-D and malathion applied epicutaneously on two days or over four weeks failed to elicit delayed-type hypersensitivity (DTH). Cptafol produced DTH responses at both dose levels tested. Following two applications, ear thickness, incorporation of 5-[125I]iodo-2'deoxyuridine-labelled cells, and histology of ears indicated swelling and cellular infiltration. Multiple sensitizations over the period of a month also produced DTH as indicated by increases in ear thicknesses. Mice pretreated with cyclophosphamide produced larger responses 24 hours post-challenge but equivalent responses at 48 hours as compared to mice pretreated with saline. Sensitization with a known sensitizer, dinitrofluorobenzene, also elicited DTH.
Neither 2,4-D- nor MMA-specific IgE antibodies were detected in serum during the four week epicutaneous sensitization period. Low titers of dinitrophenyl-specific IgE were elicited in mic treated with dinitrofluorobenzene.

title: A Linear Programming Analysis of Several Determinants of Profit on a Simulated Northern Utah Dairy Farm
Creators: name: Atwood, Jay Dee
Publisher: name: Utah State University
Year: 1983

description: The purpose of the study was to analyze several determinants of profit on a simulated northern Utah dairy farm. A linear programming model was developed to accomplish this. Optimal conditions on the farm were estimated and then other model applications were made to evaluate the importance of milk price, cropland ownership, and corn silage production and feeding. The significance of cow quality also was estimated.
Optimal conditions on the farm gave rates of return to capital between savings rates and loan rates obtainable at a financial institution. Marginal values derived for land did not support the current asking price of land. The marginal values derived for cows would support higher levels of investment in the cows than current prices of the cows. Optimal crop mixes and rations also were derived.
Milk price had a direct effect on financial measures of the farm's well-being. Increasing herd size was found to be a logical response to a decrease in milk price. Cropland ownership had an inverse effect on returns but a direct effect on annual income. Corn silage production was found to be more important for a poorer herd than a better herd. However, corn silage production and feeding had a near neutral effect on measures of financial well-being.
Essays on Overlapping Generations Models and Social Security
Creators: name: Moretto, Mauro
Publisher: name: Carnegie Mellon University
Year: 2021
Subjects: Economics

description: In this chapter, I introduce an Overlapping Generation (OLG) model where the Social Security Security system endowed with a Trust Fund. In economic literature, Social Security has traditionally been approximated as a “pay-as-you-go” (“PAYGO”) system, which fails to take into account the fact that, in reality, retirement benefits depend on the lifetime earnings of each retiree and the solvency of the Social Security fund itself. These factors are highly relevant for policy purposes because, based on current projections, Social Security will exhaust its trust fund by 2034, and will no longer be able to pay scheduled benefits to retirees.Therefore, a model that incorporates these factors represents a significant innovation in the literature andcould serve as a guide for policy makers with regard to potential policy reforms. In Chapter 1, I successfullydevelop the proposed model of Social Security, accounting for lifetime earning histories and the potential for bankruptcy of the fund in a stochastic environment.

description: We examine the linear density contrast at collapse time, $δ_c$ for large-scale structure in dynamical dark energy cosmologies, including models with early dark energy. Contrary to previous results, we find that as long as dark energy is homogeneous on small scales, $δ_c$ is insensitive to dark energy properties for parameter values fitting current data, including the case of early dark energy. This is significant since using the correct $δ_c$ is crucial for accurate Press-Schechter prediction of the halo mass function. Previous results have found an apparent failing of the extended Press-Schechter approach (Sheth-Tormen) for early dark energy. Our calculations demonstrate that with the correct $δ_c$ the accuracy of this approach is restored. We discuss the significance of this result for the halo mass function and examine what dark energy physics would be needed to cause significant change in $δ_c$, and the observational signatures this would leave.

title: An Extension Teaching Demonstration Using Broiler Chicks as a Model
Creators: name: Ishaya, Joseph B.
Publisher: name: Utah State University
Year: 1983

description: This test demonstration was intended to develop a modern management program to improve broiler production in Nigeria through extension teaching methodology. The management programs included animal health, nutrition, and general care.
Some of the factors that limit broiler production in Nigeria are associated with the management strategy presently adopted by Nigerian subsistence farmers.
This report considers the effect of different protein sources on broiler nutrition and the techniques necessary to get the farmers to practice the result of up-to-date research findings.
The extension teaching demonstration reported here is based on 60 day-old chicks. Chicks were randomly assigned to two pens, Pen A and Pen B at the Utah State University poultry farm. Pen A had 40 chicks and Pen B had 20 chicks. Chicks in Pen A received Diet #1 (corn-cottonseed meal).
Chicks were weighed weekly starting on July 2, 1983 which was the third week of the demonstration. The difference between the weekly weight gain was obvious. Birds fed corn-soybean diet were superior to those fed corn-cottonseed meal diet. The birds in Pen A were marketable at eight weeks whereas those in Pen B were not marketable at the same chronological age.
A field day was conducted at the poultry farm to report the results of the demonstration.
title: Locoweed Poisoning in Cattle: An Overview of the Economic Problems Associated with Grazing these Ranges
Creators: name: Barnard, John E.
Publisher: name: Utah State University

description: Locoweed poisoning, caused by ingestion of certain species of Astragalous and Oxytropis, has had serious economic impacts through a loss of productivity in livestock. This study has attempted to evaluate losses suffered by livestockmen grazing their cattle on areas infested with locoweed species. The results indicate a serious economic impact on these individuals.
Personal interviews were carried out with five cattle ranchers faced with typical locoweed problems. These beef cattle operations were located in Utah, Wyoming, and New Mexico. All of these producers described similar problems and losses due to locoweed poisoning. Information obtained from these interviews was used to estimate a 1978 dollar loss for three ranches, running in common, and located near Park Valley, Utah.
This study found the problem areas to be: (1) reduced weaning weights of calves; (2) increased requirements in the number of replacement heifers; (3) an increase in death loss; (4) reproductive problems (abortions and infertility); and (5) increased costs associated with labor and management problems. The summation of economic losses in each of these problem areas reflected a total estimated loss of $30,689.02 in 1978.
To determine if locoweed poisoning had long-range effects on weight gains, a sample of 20 calves were put on a 138-day feeding experiment. Of these 20 calves, 12 had grazed a locoweed-infested area, while the remaining 8 had no access to the plant. Overall average gain of both groups was found to be nearly identical. This indicates that animals will recover with proper but, sometimes, costly management.
Profitability of spraying locoweed-infested ranges with 2,4-dichlorophenoxy acetic acid (2,4-D) was determined through information supplied by the Wyoming rancher. An internal rate of return of 39.4 percent was found by using this method of locoweed control in this particular instance.
Ranchers interviewed in this study estimated their losses due to locoweed poisoning to be from 30 to 40 percent reduction in profit. Although profit margins were not determined, the estimated loss of $30,689.02 found in this study would be close to their determination. With the rampant increase in operating costs which have occurred in the past decade, producers could not long endure losses of this magnitude. However, it was determined that with proper plant control and management these losses could be substantially reduced.
title: A Dynamic Optimization Model of energy Related Economic planning and Development for the Navajo Nation
Creators: name: Beladi, Hamid
Publisher: name: Utah State University
Year: 1983

description: The Navajo reservation located in portions of Arizona, New Mexico and Utah is rich in low sulfur coal deposits, ideal for strip mining operation. Presently, the Navajo Nation has entered into extensive coal leases with several large companies and utilities. Contracts have committed huge quantities of Navajo coal for mining.
The present research has been directed to evaluate the shadow prices of Navajo coal and identify optimal coal extraction. An economic model of coal resource extraction over time has been structured within an optimal control problem has been formulated as a discrete dynamic optimization problem.
A comparison of the shadow prices of coal deposits derived from the dynamic model with the royalty payments the tribe receives on the basis of the present long-term lease contracts indicates that in most cases the tribe is paid considerably less than the amount of royalty projected by the model. Part of these discrepancies may be explained in terms of the low coal demand condition at the time of leasing and due to greater uncertainties with respect to the geologic information and other risks associated with mining operations. However, changes in the demand for coal with rigidly fixed terms of royalty rates will lead to non-optimal extraction of coal.
A corrective tax scheme has been suggested on the basis of the results of this research. The proposed tax per unit of coal shipped from a site is the difference between the shadow price and the present royalty rate. The estimated tax rates over time are derived.
