title: Spatial Impact of Factor Payments: A Case Study of Turkey Production and Processing in Utah
Creators: name: Blackham, Chesley T.
Publisher: name: Utah State University
Year: 1973

description: The purpose of this paper is to examine the importance of the spatial origin of capital or investment funds and its influence on local community incomes within the context of agricultural production and processing in a rural area in Utah.
A careful identification of the sources of capital investment can be used to determine the spatial source and flow of returns from it, and, hence, provides some indication of the extent to which local community income could be expected to change with changes in the level and mix of factors employed locally.

description: We study structure formation in the presence of primordial non-Gaussianity of the local type with parameters f_NL and g_NL. We show that the distribution of dark-matter halos is naturally described by a multivariate bias scheme where the halo overdensity depends not only on the underlying matter density fluctuation delta, but also on the Gaussian part of the primordial gravitational potential phi. This corresponds to a non-local bias scheme in terms of delta only. We derive the coefficients of the bias expansion as a function of the halo mass by applying the peak-background split to common parametrizations for the halo mass function in the non-Gaussian scenario. We then compute the halo power spectrum and halo-matter cross spectrum in the framework of Eulerian perturbation theory up to third order. Comparing our results against N-body simulations, we find that our model accurately describes the numerical data for wavenumbers k < 0.1-0.3 h/Mpc depending on redshift and halo mass. In our multivariate approach, perturbations in the halo counts trace phi on large scales and this explains why the halo and matter power spectra show different asymptotic trends for k -> 0. This strongly scale-dependent bias originates from terms at leading order in our expansion. This is different from what happens using the standard univariate local bias where the scale-dependent terms come from badly behaved higher-order corrections. On the other hand, our biasing scheme reduces to the usual local bias on smaller scales where |phi| is typically much smaller than the density perturbations. We finally discuss the halo bispectrum in the context of multivariate biasing and show that, due to its strong scale and shape dependence, it is a powerful tool for the detection of primordial non-Gaussianity from future galaxy surveys.

title: Reproduction, Survival and Density of Snowshoe Hares in Northeastern Utah
Creators: name: Clark, William R.
Publisher: name: Utah State University
Year: 1973

description: This paper presents information obtained from 1972 and 1973 on the reproduction, survival and density of snowshoe hares (Lepus americanus) in Cache National Forest, Utah. The main objectives of the study were: (1) to estimate population densities; (2) to measure adult and juvenile mortality ; and (3) to measure natality rates , including recruitment (realized annual natality).
Live-trapping and snaring were used to estimate population levels and to collect hares for necropsy. Fecal pellet counts were used to evaluate relative habitat use by hares.
The results of this study were compared to other studies of snowshoe hare ecology in North America. Based on the density, survival and reproductive output observed, recommendations were made for the management of snowshoe hares in Utah.
title: Replication: A Teaching Technique and its Impact on Student Open-Closedmindedness
Creators: name: Decker, Dale H.
Publisher: name: Utah State University
Year: 1972

description: The problem for the study was the lack of research on the effect of the empirical replication technique on student closed-mindedness. The replication technique requires the student to repeat, or replicate, studies originally conducted by social scientists. In this sense, replication is roughly analogous for the social sciences to what laboratory experiments are for the natural sciences. Additionally, the relationship between college student adjustment-maladjustment and open-closed-mindedness were explored while controlling for sex and academic achievement.
The control group (N•61) attended two lectures and a discussion section per week which dealt with introductory social science materials. The experimental group (N•BS) was exposed to the normal instruction plus performing empirical replications. The data were analyzed using three stages of statistical analysis; Pearson product-moment correlations, two-way analysis of variance, and covariance.
The difference between the posttest dogmatism means of replication and control students was not significant at the .05 level. However, the null hypothesis preducting no difference between maladjusted and non-maladjusted subjects mean posttest D-Scale scores was rejected at the .01 level of significance, Although the replication control group posttest difference was not significant at the .05 level, the reduction in mean pre to post D-Scale mean scores for the experimental group was twice the reduction for the control group and would have been significant with alpha set at .10. These findings lead to the conclusion that although its effect was not statistically significant in this study, the replication technique may still hold educational promise meriting further research.

title: Homeward the Course of Empire: The Popularization of the American West in Great Britain, 1850-1913
Creators: name: Breaden, Ian Craig
Publisher: name: Utah State University
Year: 1992

description: Images of the American West in Britain became prevalent in British popular culture during the late-nineteenth and early-twentieth centuries. This popularity arose out of the shared ethic of the Anglo myth. This myth was based upon the confidence gained from a growing industrial complex and the application of the Christian "Genesis" to the new Edens, the American West and the British Empire.
The Anglo myth could be found in British adventure novels set in both the West and empire. "Buffalo Bill" Cody used it in his Wild West, and Samuel Franklin Cody utilized it in his frontier melodramas as well as in creating his own flamboyant self-image.
The continued existence of romantic, western imagery raises questions concerning myth and reality in the formation of thought about both the American frontier and the British Empire.

description: Recently, a measure for the non-Markovian behavior of quantum processes in open systems has been developed which is based on the quantification of the flow of information between the open system and its environment [Phys. Rev. Lett. 103, 210401 (2009)]. The information flow is connected to the rate of change of the trace distance between quantum states which can be interpreted in terms of the distinguishability of these states. Here, we elaborate the mathematical details of this theory, present applications to specific physical models, and discuss further theoretical and experimental implications, as well as relations to alternative approaches proposed recently.

Manuel Gonzalez Prada and two trends in Peruvian poetry.
Creators: name: Statton, Marian Joyce
Publisher: name: University of British Columbia
Year: 2011

description: While González Prada was mainly a prose writer and ideologist, he did write poetry throughout his life, beginning perhaps even before he began to write prose. Although his poetry itself had little influence on other poets, the ideas which lie behind it did. The purpose of this paper is to show that there are two incipient trends of Peruvian poetry in Prada's poems: Modernism and indigenism. Prada’s tendency towards Modernism is found to be mainly theoretical and ideological, as his adoption of modernist style occurs when Modernism has already been established by Rubún Darío, and disappears after the publication of Exóticas in 1911. Chocano serves as a counterpoint to Prada in showing the extent to which the latter had any real influence on the development of a particular modernist poet, and to which the full development of Modernism differed from the innovations which Prada had envisioned. The incipient indigenism in Prada's poetry is represented in Baladas peruanas, although the point in which Prada anticipates twentieth century writers is that of the use of poetry as a vehicle for ideas, and as such is also evident in Libertarias and Presbiterianas. The nature of Prada’s indigenism is compared to that of Chocano in order to show the extent of the modernists' failure to develop the trends which Prada had foreshadowed.
title: An Evaluation of Stress Induced Mortality of Stocked Catchable-Sized Rainbow Trout in Temple Fork of the Logan River
Creators: name: Gresswell, Robert Earl
Publisher: name: Utah State University
Year: 1973

description: The level of stress imposed by population pressure, handling and live transportation on planted catchable-sized rainbow trout in a northern Utah stream was examined. Production of adrenocorticotrophin, as measured by interrenal ascorbic acid and serum cortisol levels, did not occur in transported or planted fish.
Dead or moribund fish collected from stream or live boxes comprised 13 percent of the 2,000 fish planted. Aeromonas salmonicida, the causative agent of furunculosis, was isolated from 41 percent of 106 moribund fish sampled. In addition, 39 percent of the samples exhibited bacterial growth other than A. salmonicida. Apparently, handling, transportation, and planting did cause low levels of stress sufficient enough to induce stress-mediated diseases such as furunculosis.
Vacuum polarization by a scalar field in de Sitter spacetime in the presence of global monopole

description: In this paper we analyse the vacuum polarization effects associated with massive scalar quantum fields in a higher-dimensional de Sitter space in the presence of a global monopole. Because this analysis has been developed in a pure de Sitter space, here we are mainly interested on the effects induced by the presence of the global monopole. So, in order to achieve this objective we calculate the corresponding Wightman function, which is expressed in an integral representation and explicitly depends on the parameters associated with the presence of the monopole and the cosmological constant. Admitting that the former is closed to the unity, which corresponds to a realistic value predicted by Grand Unified Theories, it is possible to express this function as the sum of two terms: the first one corresponds to the Wightman function on the bulk where the global monopole is absent, and the second one is a contribution induced by the presence of the monopole.

title: An Evaluation of a Self-Guided Visitor Tour at Bear River Migratory Bird Refuge
Creators: name: Kohler, Steven J.
Publisher: name: Utah State University
Year: 1971

description: In 1967 this study was initiated to evaluate the self-guided visitor tour of Bear River Migratory Bird Refuge. A 20 page visitor information booklet and tour guide was prepared and published for distribution at the refuge, and its effectiveness in telling the refuge story was evaluated. To gain a measure of the self-guided tour in terms of quality, visitor use patterns and satisfactions were critically examined.
To gather data on visitor use of the refuge, the visiting public was directly sampled by three methods: mail questionnaires, on-site interviews and candid tower observations of groups on the tour.
The information and tour guide booklet was not as effective as it should have been in telling the refuge story. Only one-fourth of the visitor groups purchased the guide, and only about half of these groups used it to any degree at the refuge.
Based on expressions of visitor satisfaction, the self-guided tour at Bear River Refuge should be termed a quality recreational activity. The continued quality of the tour depends upon sustained proper management and development of the refuge area to maintain it as a prime nesting and feeding area for migratory birds.

description: The human myiasis or infestation of larvae of various species of fly bots is uncommon but interesting health challenge in some parts of the world. The basic knowledge of this disease, however, should be beneficial to clinicians across disciplines as a spectrum of manifestations involving various organs are described in the medical literature. The extremity involvement is rather uncommon and is often found with underlying associated conditions. The diagnosis and identification of the causative species is important for documentation and management. Clinical suspicion, wound lavage, dressing, and debridement are important steps in optimal management. Appropriate systemic pharmacotherapy is supplemented for quick recovery. Prevention, however, coupled with avoidance of predisposing factors is the best management in both community and health-care settings. As the disease is more commonly noted in lower socioeconomic conditions and rural settings, the working knowledge of this condition should come in handy in anticipating, suspecting, and thus diagnosing the condition early for a prompt recovery.

description: This study estimated the 1972 costs and returns, and analyzed the physical response and economic relationships of corn hybrids for silage and grain production in some counties of Utah.
Average size of enterprise, land value and equipment value were estimated for silage and grain corn production in Utah.
Labor requirements for land preparation, growing and harvesting of silage and grain corn production were averaged. Net returns and costs (variable and fixed) for silage and grain corn production were computed in 30 farms of 15 counties of Utah to find the total production cost.
Yields, total cost, total revenue and economic profit for the hybrid seed varieties for silage and grain corn trials established in 1971 and 1972 are presented in the corresponding tables.

Creators: name: Bair, Lyle A.
Publisher: name: Utah State University
Year: 1974

description: Characteristics of nonparticipating Utah counties and municipalities in the Land and Water Conservation Fund Act of 1965 were studied. Specific objectives studied were: (1) program awareness, (2) program understanding, and (3) reasons for nonparticipation from 1965 to 1970.
A telephone survey was conducted of all nonparticipating counties, all nonparticipating municipalities larger than 2500 population and a simple random sampling of municipalities smaller than 2500 population. Results were compared on a governmental unit and regional basis.
The survey determined that, as a whole, less than 45 percent of nonparticipating Utah counties and municipalities were aware of the program. The greatest awareness was among the large municipalities of region one and the least awareness was among the small municipalities of region two. County awareness was similar in both regions.
Significant differences in program awareness occurred only when small municipalities were compared with large municipalities and counties.
Generally, the surveyed governmental units aware of the program had a low degree of program understanding, particularly with regards to who administered the program in Utah.
Reasons given for nonparticipation were primarily: (1) no need for parks, (2) unable to provide the local matching share of a grant, (3) did not want to become involved with the federal government, and (4) lack of community leadership.
As a whole, a significant number of governmental units not aware of the program would seek federal assistance if they had a recreation resource to develop.

description: We consider identical copies of spin glasses in finite dimension coupled at the boundaries. This allows to identify the spin glass analogous of twisted boundary conditions in ferromagnetic system and leads to the definition of an interface free-energy that is positively defined and that should scale with a positive power of the system size in the spin glass phase. In this note we study the behavior of the interface at the spin glass critical temperature $T_c$ within mean field theory. We show that the leading scaling of the interface free-energy does not depend on replica symmetry breaking, and can be obtained by simple scaling arguments using a cubic theory for critical spin glasses.

title: Determination of Crop Production Functions as Related to Soil Moisture and Nitrogen
Creators: name: Bauder, James W.
Publisher: name: Utah State University
Year: 1974

description: Soil moisture and nitrogen are often the primary controlling factors of crop production . Production functions are valuable in describing crop responses to such controlling factors. Such functions are al so needed for determining the economic reliability of crop production.
Soil moisture and nitrogen fertilizer were maintained at various levels to determine the response of field corn to these controlling factors. A conventional split plot design, a continuous function experimental design, and a confined barrel plot design were used to obtain data for determining production functions.
The complete factorial, conventional split plot data was successfully used to generate reliable production functions in two locations. The multiple correlation coefficient was approximately 0. 68. The continuous function design consisted of a large number of treatment combinations with only small sequential increments in treatment levels , from plot to plot. This made it possible to eliminate border rows and use a much smaller plot size. The design was tested in two locations, using 10 soil moisture levels and 22 nitrogen fertilizer levels. The multiple correlation coefficients were about 0.33 and 0.49. Using this design, it was necessary to replicate entire blocks.
The production functions from the conventional split plot design and continuous variable plot design compared favorably within locations, but not between locations. Production functions were also determined for relative yields and treatments . The inputs were expressed as fractions relative to both the maximum and optimum levels. The relative production functions were similar for both locations. The production functions were tested for transferability by making adjustments in the input data to account for site specific controlling factors. No definite conclusions were possible although the results suggest that transferability is possible.
Several reduced field designs were also tested using the data obtained. Three different incomplete factorial, split plot designs appear to be suitable for generating production functions. Grouping of the continuous function plots to as few as four soil moisture levels by four fertilizer levels also gave reliable production functions. Several suggestions regarding the use of reduced field designs are presented along with suggested future research needs in this area . The data indicate that the continuous variable design is quite useful for determining production function s. The barrel plots consisted of field corn grown under various treatment combinations on undisturbed soil cores. The data obtained from these barrel plots (210 liters) were too variable to generate a reliable production function.

description: By informed design novel high-surface area, low volume flow cells were designed for high-throughput detection of chemical and electrochemical dissolution products of energy storage materials found in zinc-air batteries, including current collectors and bifunctional catalysts. Novel flow cells were fabricated by stereolithography to realise complex flow channels which allowed efficient transport of dissolution products from the working electrode. Due to appropriate construction material selection, the 3Dprinted flow cells could withstand concentrated alkaline solutions . Routine analysis in 1 M KOH electrolytes were realised by adapting an ICP-OES to withstand harsh alkaline conditions, providing real-time detection limits below 1 ng s-1 cm-2. Positive electrode current collector candidates for alkaline zinc-air batteries were investigated for stability in 1 M KOH as function of potential region and galvanostatic charging currents within relevant for practical energy storage applications. A range of nickelsubstituted cobalt oxides NixCo3-xO4 bifunctional electrocatalysts for zinc-air batteries were synthesised and characterised by PXRD, SEM and cyclic voltammetry. With online dissolution analysis, the stability of the materials were assessed as a function of potential and pH. Nickel substitution was found to affect the onset of cobalt dissolution, and a correlation between nickel doping, dissolution magnitude of cobalt and catalytic activity towards the oxygen reduction reaction and oxygen evolution reactions was found.

description: Superdeformed (SD) states in $^{40}$Ar have been studied using the deformed-basis antisymmetrized molecular dynamics. Low energy states were calculated by the parity and angular momentum projection (AMP) and the generator coordinate method (GCM). Basis wave functions were obtained by the energy variation with a constraint on the quadrupole deformation parameter $β$, while other quantities such as triaxiality $γ$ were optimized by the energy variation. By the GCM calculation, an SD band was obtained just above the ground state (GS) band. The SD band involves a $K^π= 2^+$ side band due to the triaxiality. The calculated electric quadrupole transition strengths of the SD band reproduce the experimental values appropriately. Triaxiality is significant for understanding low-lying states.

title: A Manometric Method for the Determination of Soil Carbonates in the Field
Creators: name: Polyzopoulos, N. A.
Publisher: name: Utah State University
Year: 1959

description: In soil survey work the method now generally used to evaluate the carbonate content of the soil in the field is to observe the amount of effervescence that takes place when the soil reacts with dilute acid. The four degrees of effervescence usually recognized are designated by the symbols eo, e, es, ev and correspond roughly to a lime content of 0-0.5, 0.5-3, 3-15, and above 15 per cent, respectively. This, or course, is a very rough estimate and therefore a method is needed for the quantitative determination of carbonates in the field with a fair degree of accuracy. If such a method were available it would be possible for the soil surveyor to follow accurately in the field the distribution of lime down the profile. It would also make possible the detection of lime "bulges," a consideration of primary importance in soil classification. The method would also be useful to agricultural advisers, especially in connection with the problem of lime induced chlorosis.
There is a large variety of methods for the determination of soil carbonate in the laboratory with varying degrees of accuracy but none of them is very suitable for field use as they either employ complicated apparatus, or in other ways require laboratory facilities. The present study is concerned with the development and evaluation of a rapid method for the determination of soil carbonate in the field. The apparatus used is very simple and easy to carry and to handle under field conditions. The results obtained are sufficiently accurate for the purpose intended; Their accuracy being above that of the semiquantitative effervescence test.
The proposed method is now rendered particularly useful by the availability on the market of small portable kits for the determination of soil moisture in the field which permit the expression of results on a dry basis.

description: Timmes, Brown & Truran found that metallicity variations could theoretically account for a 25% variation in the mass of 56Ni synthesized in Type Ia supernovae (SNe Ia), and thus account for a large fraction of the scatter in observed SN Ia luminosities. Higher-metallicity progenitors are more neutron-rich, producing more stable burning products relative to radioactive 56Ni. We develop a new method for estimating bolometric luminosity and 56Ni yield in SNe Ia and use it to test the theory with data from the Supernova Legacy Survey. We find that the average 56Ni yield does drop in SNe Ia from high metallicity environments, but the theory can only account for 7%--10% of the dispersion in SN Ia 56Ni mass, and thus luminosity. This is because the effect is dominant at metallicities significantly above solar, whereas we find that SN hosts have predominantly subsolar or only moderately above-solar metallicities. We also show that allowing for changes in O/Fe with the metallicity [Fe/H] does not have a major effect on the theoretical prediction of Timmes, Brown & Truran, so long as one is using the O/H as the independent variable. Age may have a greater effect than metallicity -- we find that the luminosity weighted age of the host galaxy is correlated with 56Ni yield, and thus more massive progenitors give rise to more luminous explosions. This is hard to understand if most SNe Ia explode when the primaries reach the Chandrasekhar mass. Finally, we test the findings of Gallagher et al., that the residuals of SNe Ia from the Hubble diagram are correlated with host galaxy metallicity, and we find no such correlation.

title: Irrigation Water Values in Cache County, Utah
Creators: name: Fife, Marlyn
Publisher: name: Utah State University
Year: 1967

description: In Utah all water, both on or below the ground surface, is considered public property. The right to use water is obtained by fellowing certain subsiding procedures of appropriation through the office of the State Engineer. Any right to the use of water may be changed to some other beneficial use with the approval of the State Engineer; however, there must be no interference with other rights, unless proper compensation has been made.
Agriculture still uses most of the available water in Utah; However, farmers' needs for water are not exactly the same. When allocation per acre is the same among farmers, water soon comes to have different values. Unless some mechanism arises to permit transfer of water, misallocation results. the Cache Valley area was chosen to illustrate the Misallocation problem.
Input-output data which the Bureau of Reclamation used in their feasibility report on the Cache County area of the Oneida project were analyzed to determine the value of residual water. All factors of production except water, such as land, capital, seed, fertilizer, fuel, labor, and repairs were calculated at their market prices. These were subtracted form the value of a unit of product and the residual value was then imputed to water as one estimate of its value. Varying farm sizes and different cropping practices were studied to show the effect these variables had on water values.
Agricultural water users on the Logan River distribution system were interviewed to find the value of water rentals and water-right sales. The water-right prices quoted by farmers and irrigation company officials were stated in terms of dollars per share. Since a share delivers varying quantities of water along the complete river system the "right" values were converted to vale per acre-foot. local customs, existing water laws and past court decisions were examined to ascertain their role in water transfer.
The principle of equal marginal value was applied to Logan River water supplies. Marginal value in use reflects the amount in dollars which consumers would be willing to pay for the last unit of water consumed. In a perfectly competitive rental market the price of water reflects the value of the marginal product.

description: Many papers have speculated on the possibility of applying peer-to-peer networking concepts to networks that exist in the physical world such as financial markets, business or personal communication and ad hoc networking. One such application that has been discussed in the literature has been the application of peer-to-peer to corporate supply chains to provide a flexible communication medium that may overcome some classical problems in supply chain management. This thesis presents the design, development and evaluation of a system which implements a peer-to-peer supply chain system. A general, flexible peer-to-peer network was developed which serves as a foundation to build peer-to-peer data swapping applications on top of. It provides simple network management, searching and data swapping services which form the basis of many peer-to-peer systems. Using the developed framework, a supply chain focussed application was built to test the feasibility of applying peer-to-peer networking to supply chain management. Results and discussion are presented of a scenario analysis which yielded positive results. Several future directions for research in this area are also discussed.

description: We propose a method for measuring the temperature of strongly correlated phases of ultracold atom gases confined in spin-dependent optical lattices. In this technique, a small number of "impurity" atoms--trapped in a state that does not experience the lattice potential--are in thermal contact with atoms bound to the lattice. The impurity serves as a thermometer for the system because its temperature can be straightforwardly measured using time-of-flight expansion velocity. This technique may be useful for resolving many open questions regarding thermalization in these isolated systems. We discuss the theory behind this method and demonstrate proof-of-principle experiments, including the first realization of a 3D spin-dependent lattice in the strongly correlated regime.

description: Social behaviour plays a pivotal role in shaping the survival, reproduction, and group dynamics of organisms across diverse taxa. Within social groups, individuals must navigate complex social dynamics, communicate effectively, and exhibit appropriate social behaviours to maintain group cohesion and individual fitness. The acquisition of social competence, defined as the ability to adaptively adjust behaviour to the prevailing social context, is therefore crucial for successful social interactions. Evidence consistently points to the early-life social environment as a key determinant of subsequent social behaviour and competence. The work of this thesis aims to provide a comprehensive perspective on the interplay between the early social environment and the acquisition of social competence. I investigated the underlying mechanisms of acquisition of social competence using the cooperatively breeding fish Neolamprologus pulcher as a model species. In chapter one I investigated the impact of group size during early life on expression of social behaviour and other social traits in later life. Social competence was shaped by the early social environment with individuals raised in large groups showing increased flexibility in responding to aggression from a larger conspecific. Large-group fish showed repeatability in social competence contrary to small-group fish, suggesting they reliably show social competence across contexts. On the other hand, helping behaviour, exploration and dispersal were not influenced by the early social environment. With sufficient evidence to support previous findings that group size affects social competence, I set out to find the timing of its acquisition. I showed that early life is the only critical period for acquiring social competence, leaving no chance for recovery in the future. Thirdly, I investigated whether the behavioural patterns observed were linked to specific patterns of neuroplasticity gene expression across the Social Decision-Making Network (SDMN). I measured the expression of three neuroplasticity genes (bdnf and its receptors TrkB and p75NTR) in four regions of the SDMN. I showed that fish raised in large groups display different neuroplasticity gene expression patterns in the SDMN. Taken together my results provide further evidence of the impact of the early social environment on the acquisition of social behaviour. My results suggest that higher social complexity is more likely to yield social phenotypes compatible with group living and thus contribute to maintaining high group size, fuelling sociality in a positive feedback loop.
title: Utilization of Poultry Waste (Composted Caged-Layer) as a Supplement for Sheep Fed Straw During Late Pregnancy

description: The utilization of composed caged-layer waste (CCLW) in diets for pregnant ewes fed cereal straw was evaluated. Five sheep were assigned to five diets containing, 0, 5.72, 11.37, 23.80, and 32.69% CCLW in a 5x5 Latin square design. Water intake, feed intake and feces output were measured. Feed and feces were analyzed for dry matter, crude protein, acid detergent fiber (ADF), neutral detergent fiber (NDF), organic matter, hemicellulose and minerals. Thus, nutrient digestibility and nitrogen balance could be calculated. Forty dry, pregnant ewes in the last third of generation were assigned to four dietary treatments contained 0, 11.25, 22.08 and 31.26% CCLW in a complete randomized design. The response measured were ewe weight change, lamb birth weight and wool growth. A ewe surgically fitted with a ruminal cannula was assisted to each treatment. These ewes were adapted to diets for a 7-day period and then ruminal sumples were collected at 0, 3, 9 and 12 hours post-feeding. Connulated ewes were rotated through each treatment pen in a 4x4 Latin square design. Collected samples were analyzed for ph, volatile fatty acids, ammonia and total protozoa. Dry matter and organic matter apparent digestibility decreased as the level of CCLW increased (P

description: TTo fulfill the needs for developing the alternative energy technologies, searching for the adequate electrode materials which catalyze the electrochemical reactions utilized in devices such as fuel cell, Li-ion batteries, and related applications such as hydrogen generation and storage, has been a longstanding challenge. Among various catalysts, transition metal oxides (TMO) draw great attentions due to their low-cost, high stability, and, most importantly, a great variety of structures and electrical properties. Nonetheless, studying electrochemical reactions catalyzed by TMO is a challenging task due to the possible multivalent systems, flexible coordinations of lattice atoms, adjustable surface structures and diverse surface species. In the past decades, many innovative approaches have been explored with encouraging results; however, the mechanisms of incorporating the bulk/surface TMO structures in various chemical reactions still remain unclear. In this dissertation, using quantum mechanical calculations, we attempt to improve the fundamental understandings of how structures and electronic properties of TMO materials facilitate the electrochemical reactions of interest. To identify the possible causes for CuO and Cu structures having different selectivity in catalysis, in Chapter 3, we study the CO₂ reduction reaction (CO2RR) catalyzed by CuO (111) surface structure, and compare the results with the more widely studied Cu (100) surface. The roles played by the electronic properties of two materials in their selectivity are elucidated. In Chapter 4 and 5, we study the oxygen evolution reaction (OER) for LiCoO₂ surface structure. The structures and stabilities of Li-, O-, and H-terminated surface are investigated comprehensively. Based on the results, the formation of H-terminated surface results from Li/H exchange at the solid/liquid interface is proposed (Chapter 4). Along with the findings, we explore the possible mechanisms for the OER for non-metal terminated LiCoO₂ surface (Chapter 5). In Chapter 6, we study the oxygen reduction reaction (ORR) for Co₃O₄ (111) H-terminated surface structure. The possible reaction steps for both four-electron and two-electron pathway are investigated. In Chapter 7, the PO₄-decicient LiFePO₄/FePO₄ structures are investigated to understand how the presence of polyanion defects in the matrices could potentially improve the performance of the materials as electrodes in Li-ion batteries.

description: The transition of a counter chemotactic particle flow from a free-flow state to a jammed state in a quasi-one-dimensional path is investigated. One of the characteristic features of such a flow is that the constituent particles spontaneously form a cluster that blocks the path, called a path-blocking cluster (PBC), and causes a jammed state when the particle density is greater than a threshold value. Near the threshold value, the PBC occasionally desolve itself to recover the free flow. In other words, the time evolution of the size of the PBC governs the flux of a counter chemotactic flow. In this paper, on the basis of numerical results of a stochastic cellular automata (SCA) model, we introduce a Langevin equation model for the size evolution of the PBC that reproduces the qualitative characteristics of the SCA model. The results suggest that the emergence of the jammed state in a quasi-one-dimensional counter flow is caused by a saddle-node bifurcation.
