title: Considerations for Hood Placement and Design Downstream from a Fixed-Cone Valve
Creators: name: Prettyman, Barry Jacob
Publisher: name: Utah State University
Year: 2014

description: In many hydroelectric projects there is a need to safely dissipate the energy associated with the elevation of the water surface. When the flow is not passing through the turbines, bypass valves are often used. A valve that is commonly used is the fixed-cone valve. Fixed-cone valves, also known as Howell-Bunger valves, are devices often used to safely reduce flow energy at dams with medium to high heads. The valve directs the outflow into a conical hollow jet, which requires a large area for energy dissipation. The flow is controlled by an adjustable sleeve, also known as the gate which surrounds the valve and requires minimal power for operation even for large valves. Depending on the installation, the conical jet may need to be controlled by installing a fixed stationary hood or other structure to contain and direct the conical jet. While the hood reduces the spray, the use of the hood causes the formation of a concentrated hollow jet having a high velocity. To eliminate the hollow jet and dissipate much of the associated energy, the hood can have interior baffles. If the hood is not precisely placed relative to the valve, a phenomenon, known as backsplash, will occur. Backsplash is when a significant amount of water exits the upstream end of the hood. Backsplash is a concern for operators because it can prevent access to the valve during operation and can flood valve vaults. Because the use of fixed-cone valves and baffled-hoods are becoming more popular, the need for guidelines to correctly position the hood relative to the valve will benefit both engineers and contractors. In some hydroelectric sites, submerging the fixed-cone valve is used to control the spray and dissipate energy. Submerging the valve can have can produce violent flow conditions which can cause damage to a structure or heavy erosion. The use of a submerged fixed-cone valve is rarely used, and a submerged valve used with a baffled-hood has never been constructed. The study performed shows that the use of a baffled hood with a fixed-cone valve in submerged conditions performs well. The results may lead the way for more submerged fixed-cone valves in the future.

description: Les compétences comportementales ou « soft skills » suscitent un intérêt croissant dans les dispositifs de formation professionnelle pour leur rôle clé dans l’employabilité des jeunes. Au Maroc, l’Office de la Formation Professionnelle et de la Promotion du Travail (OFPPT) joue un rôle clé en offrant des formations techniques et professionnelles adaptées aux besoins du marché de l’emploi. Cependant, la mise en place du module « Soft Skills » à l’OFPPT témoigne d’une reconnaissance croissante de l’importance de ces compétences transversales pour l’employabilité des stagiaires. Cet article vise à analyser l’impact de l’enseignement de ces compétences transversales sur la préparation à l’emploi des stagiaires. À travers une approche méthodologique mixte combinant enquête quantitative et entretiens qualitatifs, il ressort que que la valorisation des compétences comportementales favorise non seulement l’accès à l’emploi, mais aussi la pérennité dans l’emploi et la mobilité professionnelle.

description: In the neutrino DIS diffraction the charged current non-conservation gives rise to sizable corrections to the longitudinal structure function, $F_L$. These corrections is a higher twist effect enhanced at small-$x$ by the rapidly growing gluon density. The phenomenon manifests itself in abundant production of charm and strangeness by longitudinally polarized W bosons of moderate virtualities $Q^2\lsim m_c^2$.

description: The ridge particles associated with a near-side jet are identified as medium partons kicked by the jet near the surface. They carry direct information on the parton momentum distribution at the moment of jet-parton collisions and the magnitude of the longitudinal momentum kick. The extracted early parton momentum distribution has a rapidity plateau structure with a thermal-like transverse momentum distribution. Such a rapidity plateau structure may arise from particle production in flux tubes, as color charges and anti-color charges separate at high energies.

title: Structural Change of the Western United States Alfalfa Hay Market and its Effect on the Western United States Dairy Industry
Creators: name: Cann, Joseph Patrick
Publisher: name: Utah State University
Year: 2014

description: Alfalfa is the fourth largest commodity grown in the Western U.S., representing 20% of the crop acreage over the past twenty years. In the last five years alfalfa hay price has doubled from what it was previously, indicating a possible structural change in the market. This research project was completed to test for this structural change using econometric analysis of the important demand components of alfalfa price. In addition to this, simulations of an average Utah dairy were completed to examine which ratio of forage crops provided the highest economic return to the operation. To analyze the structural change of the alfalfa hay market milk price, feeder price, commodity price, dairy inventory, alfalfa ending stocks, alfalfa exports, a structural shift dummy variable, and two proxy variables representing costs and quality were regressed, explaining 76% of the variation in alfalfa hay price. A Chow-test of the divided data set provided evidence that a structural change occurred in the alfalfa hay market circa 1994. Percent changes in the independent variables and corresponding changes in alfalfa price were calculated, showing that milk price has the largest influence over alfalfa price. An in-sample forecast showed that the regression was able to predict alfalfa hay price to within an average of $14 of the actual price over the time frame included in the analysis. The simulation of an average Utah dairy was done at three levels of production: 18,300 lbs, 22,500 lbs., and 26,700 lbs. production. Within each level of production the alfalfa to corn silage ratio was varied to represent 25/75, 50/50, and 75/25%, respectively, of the dry matter forage requirement. It was found that return to management was the greatest when alfalfa was 25% of the ration and at the lowest when alfalfa was 75% of the ration at all levels of production.

description: We developed a Monte Carlo event generator for production of nucleon configurations in complex nuclei consistently including effects of Nucleon-Nucleon (NN) correlations. Our approach is based on the Metropolis search for configurations satisfying essential constraints imposed by short- and long-range NN correlations, guided by the findings of realistic calculations of one- and two-body densities for medium-heavy nuclei. The produced event generator can be used for Monte Carlo (MC) studies of pA and AA collisions. We perform several tests of consistency of the code and comparison with previous models, in the case of high energy proton-nucleus scattering on an event-by-event basis, using nucleus configurations produced by our code and Glauber multiple scattering theory both for the uncorrelated and the correlated configurations; fluctuations of the average number of collisions are shown to be affected considerably by the introduction of NN correlations in the target nucleus. We also use the generator to estimate maximal possible gluon nuclear shadowing in a simple geometric model.

Bright Ultraviolet Regions and Star Formation Characteristics in Nearby Dwarf Galaxies

description: We compare star formation in the inner and outer disks of 11 dwarf Irregular galaxies (dIm) within 3.6 Mpc. The regions are identified on GALEX near-UV images, and modeled with UV, optical, and near-IR colors to determine masses and ages. A few galaxies have made 10^5-10^6 Msun complexes in a starburst phase, while others have not formed clusters in the last 50 Myrs. The maximum region mass correlates with the number of regions as expected from the size-of-sample effect. We find no radial gradients in region masses and ages, even beyond the realm of Halpha emission, although there is an exponential decrease in the luminosity density and number density of the regions with radius. Halpha is apparently lacking in the outer parts only because nebular emission around massive stars is too faint to see. The outermost regions for the 5 galaxies with HI data formed at average gas surface densities of 1.9-5.9 Msun/pc2. These low average densities imply either that local gas densities are high or sub-threshold star formation is possible. The distribution of regions on a log Mass - log age plot is is usually uniform along log age for equal intervals of log Mass. This uniformity results from either an individual region mass that varies as 1/age or a region disruption probability that varies as 1/age. A correlation between fading-corrected surface brightness and age suggests the former.

Creators: name: Mohtadi, Malek M.
Publisher: name: Utah State University
Year: 1967

description: This thesis is an evaluation of the methods and assumptions employed by those groups responsible for preparation of the original benefit/cost data describing the Sefeed Rood project. Benefit/cost ratios reported by the French engineering firm, Cotha Sogreah, and Plan Organization in a joint study range from 2:1 to 2.6:1 (6 and 10). A priori these seem suspect since the dam plus necessary canals and diversion works are obviously large and costly and only primary benefits are considered. The question is whether the potential benefits are likely to ever yield a positive return on investment and, if so, how long a pay-off period will be required.

subject: transparency

description: Background: Default nudges are an increasingly prominent tool for promoting healthy and sustainable food choices; however, questions of acceptance remain. While default nudges are more acceptable to the public than traditionally paternalistic tools that aim to restrict choice, they are also the least acceptable amongst nudging strategies. Little research has investigated the aspects of default nudge design that can be leveraged to better uphold freedom of choice, increase public acceptance, and therefore heighten legitimacy of default nudges. Consequently, this study examines public acceptance of five food choice default nudges with demonstrated precedent of effectiveness, as drawn from research studies and/or real-world policies, along with a design variation of each anticipated to increase acceptance. Three drivers of acceptance – perceived intrusiveness, perceived effectiveness, and own behavior – are examined. Methods: An online survey was administered in Germany (N= 451) to a sample representative of the adult population on quotas of age, gender and income. Acceptance and drivers were measured using seven-point Likert scales. Significant differences in median acceptance of the nudge were determined and displayed graphically. Ten proportional odds ordered logit models were applied and estimated using a maximum likelihood approach to investigate the mechanisms of nudge acceptance. Results: Examined changes in nudge design, particularly decreasing costliness of opting out and increasing transparency, increased the acceptance of three of the five nudges (N2.2: p = 0.000; N3.2: p = 0.000; N4.2: p = 0.008). Perceived intrusiveness emerged as the most prominent driver of acceptance (negative relationship), followed by perceived effectiveness (positive relationship). Own engagement in the target behavior of the nudge and socio-demographic variables demonstrated negligible impact on acceptance. Conclusions: Mitigating the costliness of opting out and improving nudge transparency emerge as key opportunities for choice architects to improve public acceptance, and thereby potentially identify 'sweet spots' in designing default nudges that are both effective and acceptable. The protection of individual freedom of choice and effectiveness are key aspects for choice architects to communicate to increase acceptance.

Politics and Gender: The Role Of Female Senator’s Power In Their Advocacy For Women’s Interest
Creators: name: Wu, Linhui
Publisher: name: University of Chicago
Year: 2023

description: Although progress has been made in increasing the representation of women in political institutions, their roles in the legislative process remains limited, and substantive representation of women's interests requires not only descriptive representation but also power and influence over the legislative process. The emergence of social media platforms provides a new space for politicians to express their political interests and spread over a wider audience. Examining senators' public rhetoric on social media can provide insights into their potential legislative interests and attention focus, and advocacy for women's interests is crucial in promoting gender equality and social justice. This study investigates whether female senators advocate more for women's interests on social media than their male counterparts and whether female senators with higher leadership roles advocate more for women's interests. Given that female senators have a primary responsibility for improving women's interests, their advocacy and attention focuses are important indicators of their potential contributions to the legislative process. Using around public tweets of senators, this study women with higher information control and power do not necessarily advocate for women's interests more frequently. Additionally, Republican senators publish significantly fewer statements about women's interests than independent and Democratic senators. This study addresses a gap in current theories regarding the impact of women's power and status on promoting substantive representation of women, particularly on the advocacy for women's interests on social media platforms.
title: An Etiological and Host Range Study of Celery Mosaic in Utah

Publisher: name: Utah State University
Year: 1950

description: Celery mosaic 1s e virus disease of major economic importance in Utah. In yeare of severe epiphytotics. it has been a limiting factor in celery production. In 1947 losses due to this disease were estimated to exeed 8 per cent of the total crop (17). This estimate does not include losses resulting from reduction in grade or from plants discarded in the packing sheds. The celery acreage in Utah dropped from a high of 950 acres in 1946 to 750 acre. in 1947 and dropped again in 1948 to 420 acres. Leaders in the industry attributed this reduction in Acreage, in part at least, to losses incurred by the growers from celery mosaic.

Issues of governance in Papua New Guinea: building roads and bridges

description: This paper draws on the author’s recent experiences as Environmental and Social Specialist on an ADB road upgrading and maintenance project in four provinces along the Highlands Highway, as well as reports on numerous recent and ongoing road projects in several parts of the country. The emphasis is on the Highlands region, but all the evidence indicates that the issues canvassed here apply throughout Papua New Guinea. By and large villagers, townspeople, businessmen, bureaucrats and politicians throughout Papua New Guinea are keen to see new roads built and existing roads improved, or at least maintained properly. Despite this enthusiasm for roads, for a host of reasons broached in this paper it is becoming increasingly difficult to implement road and bridge construction and improvement works throughout the country. The issues are broadly those of governance, which, following UNDP (1997) I take to mean: ‘the exercise of political, economic and administrative authority to manage a nation’s affairs. It is the complex mechanisms, processes and institutions through which citizens and groups articulate their interests, exercise their legal rights and obligations and mediate their differences’. In the case of roads, the current situation is far from one of ‘good governance’, as the ability of the state to exercise its functions of facilitating road development fairly and effectively has been severely compromised in recent years. At the same time, and partly as a response to the ‘power vacuum’ left by the state, the citizens (in this case the traditional owners of the lands on which the roads and bridges are built) are becoming evermore forceful in asserting their rights with respect to land acquisition and compensation. The result of the burgeoning problems associated with these land acquisition and compensation issues is that road and bridge projects are suffering longer delays and increased costs.

An entanglement temperature, $T_{e}$, is then obtained for some values of spin $S$. From this, it is shown that $T_{e}$ is proportional to the intradimer exchange interaction $J$ and that entanglement appears only for antiferromagnetic coupling. The results are compared to experiments carried on three isostructural materials: KNaMSi$_{4}$O$_{10}$ (M$=$Mn, Fe or Cu).

description: Redhead duck (Aythya americana) nesting and habitat change was studied in Knudson Marsh, Utah, in 1974 and 1975, and compared with earlier studies from 1950 and 1955 on the same marsh. Water conditions in 1975 were found to be similar to those in 1950, both years of favorable habitat, yet there was a decline in numbers of redheads from 500 pair s in 1950 to 50 pairs in 1975. The number of nests found also declined from 151 in 1950 to 49 in 1975. Water conditions were poor in 1955 and slightly more favorable in 1974, but there was a decline from 95 pairs and 49 nests in 1955 to 50 pairs and 23 nests in 1974. Success of active nests was greater in the present study than in 1950, but hatching success in successful nests was greater in 1950. No appreciable change in the vegetational composition of the marsh was detected between 1950 and the present study.
Soft X-ray emission from the inner disk of M33

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We present a study, based on archival XMM-Newton observations, of the extended X-ray emission associated with the inner disk of M33. After the exclusion of point sources with L_X > 2 x 10^{35} erg/s (0.3-6 keV), we investigate the morphology and spectrum of the residual X-ray emission. This residual emission has a soft X-ray spectrum which can be fitted with a two-temperature thermal model, with kT = 0.2 keV and 0.6 keV. The soft X-ray surface brightness distribution shows a strong correlation with FUV emission, indicative of a close connection between recent star-formation activity and the production of soft X-rays. Within 3.5 kpc of the nucleus of M33, the soft X-ray and FUV surface brightness distributions exhibit similar radial profiles. This implies that the ratio of the soft X-ray luminosity (0.3-2.0 keV) to the star formation rate (SFR) per unit disk area remains fairly constant within this inner disk region. We derive a value for this ratio of 1-1.5 x 10^{39} (erg/s)/(M_sun/yr), consistent with previous studies. In the same region, the ratio of soft X-ray luminosity to stellar mass (derived from K-band photometry) is 4 x 10^{28} erg/s/M_sun, a factor of 5-10 higher than is typical of dwarf elliptical galaxies, suggesting that 10-20% of the unresolved emission seen in M33 may originate in its old stellar population. The remainder of the soft X-ray emission is equally split between two spatial components, one which closely traces the spiral arms of the galaxy and the other more smoothly distributed across the inner disk of M33. The former must represent a highly clumped low-filling factor component linked to sites of recent or ongoing star formation, whereas the distribution of the latter gives few clues as to its exact origin.

description: We show that the presence of parity-odd terms in the conductivity (or, in other words, in the polarization tensor of Dirac quasiparticles in graphene) leads to rotation of polarization of the electromagnetic waves passing through suspended samples of graphene. Parity-odd Chern-Simons type contributions appear in external magnetic field, giving rise to a quantum Faraday effect (though other sources of parity-odd effects may also be discussed). The estimated order of the effect is well above the sensitivity limits of modern optical instruments.

description: Background: Coxiella burnetii is a zoonotic pathogen, infecting humans, livestock, pets, birds and ticks. Domestic ruminants such as cattle, sheep, and goats are the main reservoir and major cause of human infection. Infected ruminants are usually asymptomatic, while in humans infection can cause significant disease. Human and bovine macrophages differ in their permissiveness for C. burnetii strains from different host species and of various genotypes and their subsequent host cell response, but the underlying mechanism(s) at the cellular level are unknown. Methods: C. burnetii infected primary human and bovine macrophages under normoxic and hypoxic conditions were analyzed for (i) bacterial replication by CFU counts and immunofluorescence; (ii) immune regulators by westernblot and qRT-PCR; cytokines by ELISA; and metabolites by gas chromatography-mass spectrometry (GC-MS). Results: Here, we confirmed that peripheral blood-derived human macrophages prevent C. burnetii replication under oxygen-limiting conditions. In contrast, oxygen content had no influence on C. burnetii replication in bovine peripheral blood-derived macrophages. In hypoxic infected bovine macrophages, STAT3 is activated, even though HIF1α is stabilized, which otherwise prevents STAT3 activation in human macrophages. In addition, the TNFα mRNA level is higher in hypoxic than normoxic human macrophages, which correlates with increased secretion of TNFα and control of C. burnetii replication. In contrast, oxygen limitation does not impact TNFα mRNA levels in C. burnetii-infected bovine macrophages and secretion of TNFα is blocked. As TNFα is also involved in the control of C. burnetii replication in bovine macrophages, this cytokine is important for cell autonomous control and its absence is partially responsible for the ability of C. burnetii to replicate in hypoxic bovine macrophages. Further unveiling the molecular basis of macrophage-mediated control of C. burnetii replication might be the first step towards the development of host directed intervention measures to mitigate the health burden of this zoonotic agent.

description: Using Monte Carlo simulations, we study the evolution of contigent cooperation and ethnocentrism in the one-move game. Interactions and reproduction among computational agents are simulated on {\it undirected} and {\it directed} Barabási-Albert (BA) networks. We first replicate the Hammond-Axelrod model of in-group favoritism on a square lattice and then generalize this model on {\it undirected} and {\it directed} BA networks for both asexual and sexual reproduction cases. Our simulations demonstrate that irrespective of the mode of reproduction, ethnocentric strategy becomes common even though cooperation is individually costly and mechanisms such as reciprocity or conformity are absent. Moreover, our results indicate that the spread of favoritism toward similar others highly depends on the network topology and the associated heterogeneity of the studied population.

description: We summarize the results from analyzing six clusters of galaxies at 0.14 < z < 0.40 observed with the Hubble Space Telescope Advanced Camera for Surveys. We derive deep composite luminosity functions in B,g,V,r,i and z down to an absolute magnitude of -14 +5 log h mag. The luminosity functions are fitted by a single Schechter function with M^*=-19.8,-20.9,-21.9, -22.0,-21.7 and -22.3 i B,g,V.r,i,z respectively and alpha=-1.3 for all bands. The data suggest that the red sequence dominates the luminosity function down to more than 6 mag. below L*, the dwarf spheroidal regime. Hence, at least at z=0.3 the red sequence is well established and galaxies down to dwarf spheroidals are fully assembled within these clusters. We do not detect the faint-end upturn (M > -16) that is observed in lower redshift clusters. If this is real, the faint-end population has originated since z = 0.3.

title: The Relationship Between Revision Behaviors and Syntax in the Spoken Narratives of Language-Impaired and Normally Developing School-Aged Children
Creators: name: Cleckler, Marilyn
Publisher: name: Utah State University
Year: 1990

description: The relationship between spontaneous revision behaviors and quantitatively measured syntax skills for language-impaired and normally developing school-aged children was investigated. Differences in revision behaviors and syntactic behaviors between the two groups of children and across three age levels were also examined. Narratives were obtained from 39 language-impaired and 39 normal-language children, aged 8 through 10 years. Correlations between spontaneous revision behavior scores and syntax scores were low to moderate. The revision behavior mean scores were not significantly different between the two groups of children. Mean syntax scores were higher for the NL children and did discriminate between LI and NL children. Among the differing age levels, spontaneous revision behavior mean scores were not found to differ significantly except for 10-year-olds, who produced statistically significantly fewer substitutions and significantly more expansions that 9-year-olds. Finally, with respect to syntax scores, 10-year-olds produced statistically significantly more words per T unit than 8- and 9- year olds and mean DSS was significantly higher for 10-year-olds as compared to 9-year-olds.

description: The stability of two quantum counter-streaming electron beams is investigated within the quantum plasma fluid equations for arbitrarily oriented wave vectors. The analysis reveals that the two quantum two-stream unstable branches are indeed connected by a continuum of unstable modes with oblique wave vectors. Using the longitudinal approximation, the stability domain for any k is analytically explained, together with the growth rate.

title: An Economic Evaluation of the Product Sugar With Special Emphasis on the Abnormal Sugar Market of 1963-1964
Creators: name: Olsen, Merlin J.
Publisher: name: Utah State University
Year: 1970

description: The product sugar is studied in detail with special emphasis on supply and demand factors, in an attempt to better understand the abnormal sugar market of 1963-1964. The unusual market fluctuations of that period appear to have been initiated by a statistical imbalance in world supply and demand of sugar. The extent of price fluctuations in the united states during 1963-1964 we accentuated by the inability of current sugar legislation to shield the U.S. market from the world market, and by the openly aggressive purchasing policies followed by the U.S. department of agriculture which further aggravated an already thin and inflated world sugar market. There is also evidence that excessive market activity on the New York Coffee and Sugar Exchange by the nonprofessional group of buyers contributed additional instability to the sugar market, along with the scare buying and hoarding which were common in the U.S. especially during the critical days of 1963.

description: « Madagascar possède une vaste étendue de gamme de productions de l’agriculture et de l’élevage » [1] (Donque, 1974). Pourtant, « la malnutrition par insuffisance d´apport alimentaire reste un défi majeur des pays à faible et moyen revenu » [2] (Lantonirina Ravaoarisoa et al. ; 2021). Notre île n’est pas épargnée.

La présente étude, vise à identifier les comportements de consommation des produits agricoles locaux qui sont parmi les déclencheurs de la malnutrition.

Une étude qualitative a été réalisée auprès de 259 ménages consommateurs des produits agricoles locaux de la commune urbaine de Mahajanga I, et qui sont répartis dans treize quartiers. Des fiches d’enquête ont été distribuées et remplies afin d’obtenir les données.

Nous avons pu obtenir la quantité des produits agricoles consommés, et les motifs qui poussent les personnes à en consommer ou non. Et nous avons pu savoir aussi que se sont surtout les personnes qui vivent seules et les ménages composés de 2 à 5 personnes qui sont les grands consommateurs des produits agricoles.

Chaque personne enquêtée reconnaisse les bienfaits des produits, même s’ils ne peuvent pas changer leur coût, ils peuvent changer leur situation actuelle.
title: Validation of the Use of the Rapid Speech Transmission Index (Rasti) In Elementary School Classrooms
Creators: name: Rao, Aparna
Publisher: name: Utah State University
Year: 1992

description: The aim of this study was to assess the validity of an objective method of speech intelligibility, the Rapid Speech Transmission Index (RASTI), in elementary school classrooms, The RASTI can be obtained more quickly than subjective measures of speech intelligibility and has been shown to be highly valid with adult listeners in auditoriums. In this study RASTI values were correlated with scores on a subjective test of speech intelligibility, the word intelligibility by Picture Identification (WIPI) test, for 45 students in two elementary classrooms (grades 1 through 3 and grade5). Results indicated that the RASTI value is a poor predictor of subjective speech intelligibility (WIPI) scores for these students. There was no significant difference between the correlations obtained in the two classrooms or between the correlations obtained with the average and largest of the three RASTI values and the WIPI scores. Further study needs to be done to determine the applicability of the RASTI to classroom environments.
Very-High Energy Gamma-Ray Flux Limits for Nearby Active Galactic Nuclei

description: Combining the results of targeted observations, H.E.S.S. has accumulated a large amount of extra-galactic exposure at TeV energies. Due to its large field of view a considerable part of the sky (0.6 sr) has been observed with high sensitivity outside the targeted observation positions. Since this exposure region contains little inherent bias, it is well suited for studies of extra-galactic source populations. Given the correlation between ultra-high energy cosmic rays and nearby extra-galactic objects recently claimed by the Auger collaboration, this unbiased sky sample by H.E.S.S. is of interest since it includes (besides the targeted sources) 63 AGN within 100 Mpc, for which very-high energy gamma-ray flux limits are derived.
