title: Milko-Tester Analysis of Milkfat Content of Churned and Nonchurned Samples from Jersey and Holstein Dairy Cattle
Creators: name: Monobe, Kazuko
Publisher: name: Utah State University
Year: 1977

description: Milk samples from three Jersey and three Holstein herds were used to determine if the degree of churning correlated with the initial milkfat assay, and also to determine if the churned milkfat could be measured as accurately as the initial milkfat using the Milko-Tester.
Regression lines for the initial milkfat test versus churned milk- fat test fit polynomial curves. The degree of churning was greater for Jerseys than Holsteins and correlated with the initial milkfat test.
The repeatability of initial milkfat tests vas 0.98 for Jerseys and 0.99 for Holsteins. However, the repeatability of churned milkfat tests was lower for both breeds, especially for Jerseys. This indicated that the churned sample could not be measured for its milkfat content as accurately as the nonchurned sample. Churned milkfat samples all tested lower than initial milkfat samples, thus the Milko-Tester Mark III was unable to provide an initial fat test estimate following sample churning.
Cows were different from each other in the difference between initia1 and churned milk fat tests. This suggested that cows which produce milk with a higher tendency for churning are apt to receive less reliable milkfat tests from central laboratories than other cows, when all milk samples are subjected to churning conditions.

description: Recent numerical investigations have uncovered a surprising result: Reissner-Nordstrom-de Sitter black holes are unstable for spacetime dimensions larger than 6. Here we prove the existence of such instability analytically, and we compute the timescale in the near-extremal limit. We find very good agreement with the previous numerical results. Our results may me helpful in shedding some light on the nature of the instability.

description: Udder edema is a disorder of the mammary gland characterized by an excessive accumulation of fluid in the intercellular tissue spaces. Pathologically, edema can be classified as either localized or generalized. Udder edema should be thought of as a localized disease because of the factors involved in the development of the disease. Statistical analysis of total serum protein, albumin, and globulin values of cows affected with udder edema compared to nonaffected cows revealed no significant differences.

description: The quantum tunneling effects between two metallic plates are studied using the time dependent density functional theory. Results show that the tunneling is mainly dependent on the separation and the initial local field of the interstice between plates. The smaller separation and larger local field, the easier the electrons tunnels through the interstice. Our numerical calculation shows that when the separation is smaller than 0.6 nm the quantum tunneling dramatically reduce the enhancing ability of interstice between nanoparticles.

description: We present a detailed X-ray spectroscopic study of the supernova remnant DEM L71 in the Large Magellanic Cloud. Based on deep $\sim 103$ ks archival {\it Chandra} data, we perform a detailed spatially resolved spectral analysis of DEM L71. We analyze regional spectra extracted from thin-sliced regions along several different azimuthal directions of the SNR to construct radial profiles of elemental abundances for O, Ne, Mg, Si, and Fe. Our elemental abundance measurements reveal an asymmetrical spatial distribution of metal-rich ejecta gas. Especially the asymmetry on the western part of the central Fe distribution is remarkable. While the location of the contact discontinuity is generally at $\sim 5$ pc from the geometric center of the X-ray emission of DEM L71, it is uncertain in western part of the remnant. Fe is enhanced in the ejecta while O and Ne abundances are generally negligible. This finding confirms the Type Ia origin of DEM L71. We estimate an upper limit on the Sedov age of $\sim 6,660\pm 770$ yr and explosion energy of $\sim 1.74\pm 0.35\times 10^{51}$ erg for the remnant. This explosion energy estimate is consistent with a canonical explosion of a Type Ia supernova remnant.

description: In this paper we consider frame-like formulation for mixed symmetry spin-tensors corresponding to arbitrary Young tableau with two rows. First of all, we extend Skvortsov formulation for massless mixed symmetry bosonic fields in flat Minkowski space to the case of massless fermionic fields. Then, using such massless fields as building blocks, we construct gauge invariant formulation for massive spin-tensors with the same symmetry properties. We give general massive theories in (A)dS spaces with arbitrary cosmological constant and investigate all possible massless and partially massless limits.

The lived experience of compassionate love at end of life
Creators: name: Hughes, ME
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis is an investigation of how people experience the death and final arrangements of a significant other person who died at home from a life limiting illness. Inspired by my own lived experience, and recognizing that subjectivity would influence this research, I decided to employ the qualitative approach of heuristic enquiry to discover new meanings from a time marked by irreplaceable loss and critical decision making. Previous studies have shown that in contemporary western society, an expected death predominantly occurs in a hospital, hospice or aged care facility. Consequently, an expected death at home is unusual and outside common experience. Furthermore, Australian social policy is committed to relocating death back into the community, not just as a cost saving measure but also based on the ideology of a good death. I argue that to make death at home a realistic option for more people, greater awareness of how people experience the death and final arrangements is needed. I also claim that despite death being an ubiquitous lifetime event, limited opportunities arise to discuss matters relating to a dead person. Given that the traditional theories of grief and bereavement have promoted 'letting go' and detaching from a relationship with the deceased, the discourse surrounding what occurs in the site of the home when an expected death prevails from a history of disease, remains largely sequestrated from people's conversations. Consequently, the aims of this research have been to discover a rich understanding of the experience at home from those with lived experience for the purpose of informing and extending the support by people at end of life. The findings from this research were generated from the wisdom and insights of twenty eight Tasmanian people. By applying the six stages of heuristic enquiry to discover new meaning from human experience, three temporal dimensions emerged, casting light upon a range of human experience. A deep and committed examination of this topic using self refiexivity and thematic analysis, discovered that the spirit guiding people's decision making at end of life is a set of experiences and responses that I have chosen to call compassionate love. In the final stage of this enquiry known as the creative synthesis, I propose a model which demonstrates how five interdependent practices of compassionate love enable the expression of human qualities of care. These practices facilitate a rich array of people's strengths, resources and capacities providing benefits not only for the person receiving the care but unveiling the potential for self growth and transformation in the journey at end of life. These findings have relevance to social work intervention at end of life and beyond because it is possible that these qualities of care may be obscured in the chaos generated by grief and overlooked when attention is directed towards the negative outcomes that so often represent the experience of bereavement.

title: Two Generational Study on the Effect of Different Levels of Fluoride on Rat Bone and Teeth
Creators: name: Upadhyay, Madhav Prasad
Publisher: name: Utah State University
Year: 1977

description: The effects of different levels of fluoride in drinking water on different parameters of femurs and incisors of female rats were studied. Rats and their offspring, before and after weaning, were used for the study. Mother rats received 0, 1 and 5 ppm fluoride in drinking water. After weaning, the offspring were given the following treatments: 0-0, 0-1, 0-5, 1-0, 1-1, 1-5, 5-0, 5-1 and 5-5; the first number indicating fluoride level of mother's water during mating, pregnancy and lactation and the second number indicating the fluoride level of water given to the offspring. Femurs and top and bottom incisors were collected from mother rats, 21 day old pups and 300g. body weight pups. Femurs were analysed for ash, calcium, phosphorus and fluoride content and breaking strength. Only fluoride analyses were done on incisors. Fluoride ion electrodes (Orion models 94-09 and 96-09) were used for fluoride analysis.
Mother rats that received 1 and 5 ppm of fluoride showed on increase in fluoride content of teeth. There was no increase in the fluoride content of weanling rat teeth suggesting that there was no maternal transfer of fluoride to the offspring.
A significant increase in fluoride content of femur and teeth of all the groups of 300g. offspring, that received 1 and 5 ppm of fluoride, was observed as compared to the control group (0-0). No significant differences in other femur parameters of 300 g. offspring were observed.
Significant differences in fluoride content of femurs and incisors of 300g. rat offspring were found due to pre and post-weaning fluoride treatments. Combined pre and post-weaning fluoride administration resulted in higher fluoride content of femurs and incisors.
At the levels used in this study, pre-weaning fluoride administration alone does not appear to affect the fluoride content of bone and teeth of the rat offspring, but fluoride, when given ofter weaning does contribute to the increased fluoride content of bone and teeth.
Use of Prostaglandin in Herd Health Programs

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1983

description: Over a two-year period, we were able to maintain records on 450 cows which were given prostaglandin. SEE CHART. Our first objective was to reduce the number of days to the next heat by five or more. We did breed slightly over 63% of the cows by the 5th day and 72% by the 8th day. The conception was better than we had hoped for. We would have been satisfied with 3% below the normal firstservice conception rate for this herd. Instead, we were 3% above the normal rate. We had a 49% conception rate on first-service following use of prostaglandin as compared to 46% herd average on first-service. The use of prostaglandin in this now 1600-cow herd has been proven to be cost-effective, and gave very satisfactory results in this field study. Selection of recipients for prostaglandin injection is determined by rectal palpation by the veterinarian during herd checks, and is now a routine part of the herd health and reproduction program.

We give an exposition of Smirnov's theorem (2001) on the conformal invariance of crossing probabilities in site percolation on the triangular lattice. We also give an introductory account of Schramm-Loewner evolutions (SLE(k)), a one-parameter family of conformally invariant random curves discovered by Schramm (2000). The article is organized around the aim of proving the result, due to Smirnov (2001) and to Camia and Newman (2007), that the percolation exploration path converges in the scaling limit to chordal SLE(6). No prior knowledge is assumed beyond some general complex analysis and probability theory.

description: We combine deep optical and radio data, from the Hyper Suprime-Cam and the Low-Frequency Array (LOFAR) respectively, to study 78 radio AGN in nearby (z<0.5) dwarf galaxies. Comparison to a control sample, matched in stellar mass and redshift, indicates that the AGN and controls reside in similar environments, show similar star-formation rates (which trace gas availability) and exhibit a comparable incidence of tidal features (which indicate recent interactions). We explore the AGN properties by combining the predicted gas conditions in dwarfs from a cosmological hydrodynamical simulation with a Monte-Carlo suite of simulated radio sources, based on a semi-analytical model for radio-galaxy evolution. In the subset of LOFAR-detectable simulated sources, which have a similar distribution of radio luminosities as our observed AGN, the median jet powers, ages and accretion rates are $\sim 10^{35}$ W, $\sim 5$ Myr and $\sim 10^{-3.4}$ M$_{\odot}$ yr$^{-1}$ respectively. The median mechanical energy output of these sources is $\sim100$ times larger than the median binding energy expected in dwarf gas reservoirs, making AGN feedback plausible. Since special circumstances (in terms of environment, gas availability and interactions) are not necessary for the presence of AGN, and the central gas masses are predicted to be an order of magnitude larger than that required to fuel the AGN, AGN triggering in dwarfs is likely to be stochastic and a common phenomenon. Together with the plausibility of energetic feedback, this suggests that AGN could be important drivers of dwarf-galaxy evolution, as is the case in massive galaxies.

I understand there is another one in the northeast. It's an on-farm computer terminal. It doesn't have to be anthing high powered. It can be just a small, portable unit with a telephone connection with the DHIA computer in Raleigh. It allows you to have daily input, status changes on cows, and call that information back and I'll show you some of the other things it will do.

Creators: name: Brown, Rodney Jay
Publisher: name: Utah State University
Year: 1977

description: A process which incorporates whey sol ids, primarily protein, into cheese to increase cheese yield and eliminate whey handling problems was evaluated. Whey was concentrated by ultrafiltration to levels of 9.8 to 20.3 percent total solids (4.3 to 7.1 percent protein), heated at 70 C for 30 minutes and added to cheese milk with the coagulating enzyme.
Increase in cheese yield, on the basis of 39 percent moisture, for 10 pairs of samples was 4.0 ± 2.8 (S.D.) percent. This increase was significant at alpha less than 0.001. Moisture and protein content increased while fat content decreased. Setting time and pH also decreased. Body/texture evaluation showed no change, but flavor scores decreased. Specific defects responsible for changes in flavor and body/texture were identified.

description: The hybrid Monte Carlo (HMC) algorithm is applied for the Bayesian inference of the stochastic volatility (SV) model. We use the HMC algorithm for the Markov chain Monte Carlo updates of volatility variables of the SV model. First we compute parameters of the SV model by using the artificial financial data and compare the results from the HMC algorithm with those from the Metropolis algorithm. We find that the HMC algorithm decorrelates the volatility variables faster than the Metropolis algorithm. Second we make an empirical study for the time series of the Nikkei 225 stock index by the HMC algorithm. We find the similar correlation behavior for the sampled data to the results from the artificial financial data and obtain a $ϕ$ value close to one ($ϕ\approx 0.977$), which means that the time series has the strong persistency of the volatility shock.

title: The Affect of the Placement of Food on the Tray and the Scheduling of Playtime on Plate Waste and Nutrient Intake by Elementary School Children
Creators: name: Walton, Elise
Publisher: name: Utah State University
Year: 1977

description: For three weeks the plate waste from the students at the Edith Bowen Laboratory School was collected. The students were divided into three units by grade; Unit I, kindergarten and first grade, Unit II, second and third grade; and Unit III, fourth through sixth grade. The total waste of the individual menu items in the three units was weighed to determine the total waste of each food item for the unit. In each unit individual food items from three control trays weighed together, and an average serving portion for the item in each of the three units was obtained. The study consisted of three phases, each lasting five consecutive school days with one control phase and two experimental phases. During the control phase (Phase 1) the dessert was placed on the front of the tray, in relation to the children and the children played after lunch. The dessert was placed on the back of the tray in relation to the children and playtime was after lunch in Phase 2. In Phase 3, the dessert was placed again on the back of the tray, but playtime was before lunch. The placement of food on the tray had no measurable affect on the amount of food wasted. When the children played before lunch there was a significant decrease in the amount of food wasted. The meals as served, consumed, and wasted were analyzed for 22 nutrients, and the nutrient density or Index of Nutritional Quality of the meals was also determined. The meals as served were examined to see if they met the nutrient requirements for a Type A lunch.
Studies on the depressive action of chromate and dichromate salts on galena
Creators: name: Okada, Susumu
Publisher: name: University of British Columbia
Year: 2011

description: In the course of the experimental work conducted it was found that when galena was treated with chromate salts or dichromate salts in an aqueous solution, lead chromate identified by infrared spectroscopy was the main species adsorbed on the galena surface. The formation of chromium hydroxide or chromium oxide was not observed. Thermodynamic considerations of the Pb-Cr-S-H₂0 bulk system indicate the very stable character of lead chromate as shown in the potential-pH diagram constructed in this study. It is also seen that no stable domain of lead dichromate exists. The adsorption rate as well as adsorption amount of dichromate at the pseudo-equilibrium condition increases with the decrease in pH value. This phenomenon supports the fact experienced in galena flotation that a dichromate salt is a much more efficient depressant than is an equivalent chromate salt. The desorption of xanthate from galena surfaces covered with more than a monolayer thickness of xanthate was found to be possible by adding chromate salt to the system, whereas chromate desorption from galena surfaces due to xanthate addition was not observed. It was found that under comparable conditions xanthate adsorbed on lead chromate surfaces oxidized to dixanthogen much more readily than xanthate adsorbed on galena surfaces.

You can make it as long as you want so you don't have problems with tearing which is another problem I run into. I'd get the incision to a certain point and chicken out and then I'd have a tear. In this case you can really make the incision as long as you like.

Es wird festgestellt, dass die lebenslange Weiterbildung der Informationskompetenz bei Wissenschaftler*innen unabdingbar ist und im Einklang mit der Steigerung der Forschungsproduktivität steht. Trotz dieser Erkenntnisse gibt es in der Fachliteratur bisher kaum nennenswerte Konzepte zur Förderung der Informationskompetenz der Forschenden in Spezialbibliotheken. Mit Hilfe der wissenskulturellen Analyse, basierend auf den Ansätzen der KIBA-Gruppe zu Informationsdidaktik und der Wissenskulturen von Karin Knorr-Cetina, wird ein Interview-Leitfaden entwickelt, mit Hilfe dessen bei 10 Mitarbeitenden des GEI eine Analyse der Wissenskultur und der Bedürfnisse durchgeführt wird. Die Ergebnisse zeigen, dass für die Förderung von Informationskompetenz ein ganzheitliches Konzept benötigt wird, welches sich nicht nur ausschließlich auf reine Schulungen beschränkt. Es sind verschiedene Formate notwendig, um die individuellen Bedürfnisse der Forschenden abzudecken. Besonders virtuelle Angebote sollen integriert werden. Die Ergebnisse lassen sich allerdings nicht auf andere Spezialbibliotheken deckungsgleich übertragen. Die wissenskulturelle Analyse kann jedoch als Grundlage angewendet werden, um auch in anderen Spezialbibliotheken ein neues Konzept zur Förderung der Informationskompetenz bei Wissenschaftler*innen zu entwickeln.

Atomic beam polarized 3He+ ion source
Creators: name: Vyse, Robert Norman
Publisher: name: University of British Columbia
Year: 2011

description: A beam of polarized ³He⁺ ions has been produced using atomic beam method techniques. This method has the attraction of being capable of producing an ion beam with polarizations up to 100%. The polarization of ³He beams presently produced by optical pumping techniques is of the order of 5%. The apparatus is composed of three main sections, the atomic beam source consisting of a supersonic nozzle cooled to liquid helium temperatures to produce a low velocity atomic beam, the tapered hexapole magnet to spatially separate the particles in the two magnetic spin substates, and the electron bombardment ionizer to produce ³He⁺ ions from the neutral ³He atomic beam. The low velocity beam is required because the nuclear magnetic moment of ³He is of the order of 1000 times smaller than the electronic magnetic moment used to separate beams in conventional Stern-Gerlach magnets and to achieve a high ionization efficiency. The measured intensity of the beam produced by the atomic beam source cooled to liquid helium temperature was 1 x 10¹⁸ atoms/sr-sec, the most probable velocity was 310 m/sec, and the velocity full width at half maximum was 50 m/sec. The beam flux through the ionizer increases by a factor of 1.3 when the hexapole field is turned on, in good agreement with the theoretically expected increase. This increase corresponds to a polarization of 65% of the atomic beam. A 12nA³He⁺ ion beam was obtained corresponding to an ionization efficiency of approximately 0.15%.

description: We report the discovery of J0624-6948, a low-surface brightness radio ring, lying between the Galactic Plane and the Large Magellanic Cloud (LMC). It was first detected at 888 MHz with the Australian Square Kilometre Array Pathfinder (ASKAP), and with a diameter of ~196 arcsec. This source has phenomenological similarities to Odd Radio Circles (ORCs). Significant differences to the known ORCs - a flatter radio spectral index, the lack of a prominent central galaxy as a possible host, and larger apparent size - suggest that J0624-6948 may be a different type of object. We argue that the most plausible explanation for J0624-6948 is an intergalactic supernova remnant due to a star that resided in the LMC outskirts that had undergone a single-degenerate type Ia supernova, and we are seeing its remnant expand into a rarefied, intergalactic environment. We also examine if a massive star or a white dwarf binary ejected from either galaxy could be the supernova progenitor. Finally, we consider several other hypotheses for the nature of the object, including the jets of an active galactic nucleus (AGN) or the remnant of a nearby stellar super-flare.

description: We study quantum transport on finite discrete structures and we model the process by means of continuous-time quantum walks. A direct and effective comparison between quantum and classical walks can be attained based on the average displacement of the walker as a function of time. Indeed, a fast growth of the average displacement can be advantageously exploited to build up efficient search algorithms. By means of analytical and numerical investigations, we show that the finiteness and the inhomogeneity of the substrate jointly weaken the quantum walk performance. We further highlight the interplay between the quantum-walk dynamics and the underlying topology by studying the temporal evolution of the transfer probability distribution and the lower bound of long time averages.

title: The Utah Forest Dynamics Plot: Long-Term Ecological Monitoring and Theoretical Ecology in a High-Elevation Subalpine Environment
Creators: name: Furniss, Tucker J.
Publisher: name: Utah State University
Year: 2016

description: The Unified Neutral Theory of Biodiversity has been advanced as a universal theory for species coexistence in forests worldwide, but few studies have examined its relevance to high-elevation, stressful environments. I established the Utah Forest Dynamics Plot (UFDP) in a heterogeneous subalpine forest at 3,091 m elevation on the Colorado Plateau to examine three underlying assumptions of neutral theory (functional equivalence, ecological equivalence, and habitat generality) and one prediction (the species abundance distribution). The UFDP comprises 27,845 stems ≥1 cm diameter at breast height of 17 species, 10 genera, and 6 families over 13.6 ha. The neutral model was a poor fit to the observed species abundance distribution, but I did not find the alternative lognormal model to provide a better fit. Using spatial pattern analyses of tree data, topography, and soil type, I found some limited support for the neutral theory assumptions of functional and ecological equivalency, with notable exceptions. Populus tremuloides, Pinus flexilis, and Pinus longaeva were characterized by non-neutral recruitment processes, and Abies bifolia and Populus tremuloides exhibited asymmetric competitive and facilitative interactions. The assumption of habitat generality was strongly contradicted, with all ten abundant species in the UFDP having habitat preference. In this subalpine temperate forest, species diversity and community structure are influenced more by habitat heterogeneity, species differences, and niche selection, with neutral processes playing a lesser role.

In both studies, male weanling rats were made anemic by bleeding and being fed a low-iron diet. Experimental diets were control fed to the animals and final hemoglobin concentrations were recorded. Animals were sacrificed and liver iron concentrations determined. The first experiment measured the iron bioavailability of mechanically-deboned and hand-deboned beef plate was better utilized by rats than the iron from mechanically- deboned shank and mechanically-deboned plate. The effect of lipid source and level on iron bioavailability of mechanically-deboned turkey meat was investigated in the second experiment. Fat from the meat was extracted before individual diets were prepared. Four lipids (corn oil, pork fat, turkey fat, or beef tallow) at three different levels (12%, 24%, or 36%) served as dietary fat sources, the effect of lipid dietary fat source and level on iron utilization was found to be negligible.

description: In the history of life, we can observe an astounding diversity of life forms. However, we still lack a thorough understanding of how different species form and even what constitutes a species. In some groups of organisms, especially in plants, hybridization between species is very common. Hybridization has the potential to create new combinations of traits, which can lead to speciation, but hybridization can also lead to extinction or demographic decline of natural populations. Within and between species, genetic variation is ubiquitous in natural populations, which can be observed on various levels. Here, I present several ways to assess such variation in the plant genus Boechera (Brassicaceae). First, I present the evolutionary history and patterns of admixture within a subgroup in the genus, the B. puberula clade. I further show through admixture analyses, that that there is variation in the extent of admixture within the group, but especially when it comes to admixture with two widespread congeners, not part of the B. puberula clade. In a second study, I assessed levels of genetic diversity and patterns of population genetic structure within a member of the B. puberula clade, the montane endemic diploid B. lasiocarpa from Utah. After excluding all hybrids based on estimated admixture proportions, I show that levels of genetic diversity based on genomic data from this rare species are higher than in the widespread B. stricta. Additionally, I assessed common and rare SNVs and show that populations of B. lasiocarpa exhibit variation in genetic diversity and population genetic structure, which seem to be consistent with assumed population sizes. Further, I investigated patterns of gene expression in an experiment under drought-stress in four Boechera species, which exhibit differences in reproductive mode and ploidy level. Across all four species, I did not find a uniform response to drought-stress, and I present evidence for apomixis-specific gene expression, for differential expression associated with ploidy as well as differentially-expressed genes under a model of potential reversal from apomixis to sexual reproduction in B. lignifera.

description: A polycrystalline sample of the hyperhoneycomb iridate $β$-ZnIrO$_3$ was synthesized via a topochemical reaction, and its structural, magnetic, and thermodynamic properties were investigated. The magnetization and heat capacity data show the absence of long-range magnetic order at least down to 2 K. A positive Curie-Weiss temperature $θ_W \sim 45$ K probed by the temperature dependence of magnetic susceptibility indicates that a Kitaev interaction is dominant. These observations suggest that a quantum spin liquid may have been realized. Furthermore, the observation of linear temperature-dependent contribution to the heat capacity with no magnetic field effect evidences gapless excitation. These facts are surprisingly contrary to the chemical disorder evidenced by the crystallographic analysis. By discussing the differences in the size effect of Z$_2$-fluxes in 2D and 3D Kitaev magnets, we propose that there is a hidden mechanism to protect the quantum spin liquid state from chemical disorder.

description: Adhesive with tape was used to repair a teat fistula in a dry cow. Many of the udders are infected and it is good practice to culture and test for antibiotic sensitivity before electing to do surgery. After thorough preparation including the instillation of a larson teat tube, the fistulous tract was excised and hemmorrhage controlled. Adhesive was thinly applied and the edges held in opposition for thirty seconds. With the elastrator band in place adhesive tape was spirally applied. A larson teat tube was left in place and the cap removed. The elastrator band was cut and removed.

description: We introduce a general method to construct one-dimensional translationally invariant valence bond solid states with a built-in Lie group $G$ and derive their matrix product representations. The general strategies to find their parent Hamiltonians are provided so that the valence bond solid states are their unique ground states. For quantum integer spin-$S$ chains, we discuss two topologically distinct classes of valence bond solid states: One consists of two virtual SU(2) spin-$J$ variables in each site and another is formed by using two $SO(2S+1)$ spinors. Among them, a new spin-1 fermionic valence bond solid state, its parent Hamiltonian, and its properties are discussed in detail. Moreover, two types of valence bond solid states with SO(5) symmetry are further generalized and their respective properties are analyzed as well.

description: 14N(p,gamma)15O is one of the key reactions of nuclear astrophysics playing a role in various stellar processes and influencing energy generation of stars, stellar evolution and nucleosynthesis. For a reliable reaction rate calculation the low energy cross section of 14N(p,gamma)15O must be known with high accuracy. Owing to the unmeasurable low cross sections, theoretical calculations are unavoidable. High precision experimental cross section data are needed in a wide energy range in order to provide the necessary basis for low energy extrapolations. In the present work the total 14N(p,gamma)15O cross section was measured with a method complementary to the available data sets. The cross section was measured with activation, based on the detection of the annihilation radiation following the beta+ decay of the reaction product 15O. This method, which provides directly the astrophysically important total cross section, was never used for the 14N(p,gamma)15O cross section measurement in the studied energy range. The non-resonant cross section was measured between 550 keV and 1400 keV center-of-mass energies with total uncertainty of about 10%. The results were compared with literature data using an R-matrix analysis. It is found that the cross sections measured in this work are in acceptable agreement with the two recent measurements only if the weak transitions - not measured in those works - are included. The present data set, being largely independent from the other available data, can be used to constrain the extrapolated cross sections to astrophysical energies and helps to make the astrophysical model calculations more reliable.

title: A Self-Instructional, Multi-Media Approach to Facilitate the Teaching of the Index of Nutritional Quality
Creators: name: Probart, Claudia Kay
Publisher: name: Utah State University
Year: 1977

description: A review of the literature dealing with nutrition education established the following: (a) that there is a need for nutrition education at the elementary school level; (b) that elementary teachers do not always have the background or motivation to meet this need for nutrition education; and (c) that new educational methods that are easier to understand and more highly motivating are needed.
The Index of Nutritional Quantity (INQ), a nutrient density concept, was developed at Utah State University to answer the need for easily understood and motivating nutrition information. The INQ method of nutrition education has been used and considered successful in actual classroom situations.
Up to this time, the INQ method of teaching was introduced to interested individuals and groups by the various members of the INQ research group--a method that is expensive in time and travel expense and lacks consistency. A less expensive, more standardized means of disseminating information about the Index of Nutritional Quality was needed
After consideration of the various types of media available, it was decided that a self-instructional, multi-media unit, including a slide-tape and an accompanying workbook, would be a satisfactory teaching module. The module was developed and tested as a part of this study, using both an attitude survey and a didactic pre-and posttest as evaluation instruments. The test statistics were significant to conclude that learning had taken place as a result of exposure to the unit; and that the module was successful as a teaching devise.

description: Gauge Higgs Unification in Warped Extra Dimensions provides an attractive solution to the hierarchy problem. The extension of the Standard Model gauge symmetry to $SO(5)xU(1)_X$ allows the incorporation of the custodial symmetry $SU(2)_R$ plus a Higgs boson doublet with the right quantum numbers under the gauge group. In the minimal model, the Higgs mass is in the range 110-150 GeV, while a light Kaluza Klein (KK) excitation of the top quark appears in the spectrum, providing agreement with precision electroweak measurements and a possible test of the model at a high luminosity LHC. The extension of the model to the lepton sector has several interesting features. We discuss the conditions necessary to obtain realistic charged lepton and neutrino masses. After the addition of an exchange symmetry in the bulk, we show that the odd neutrino KK modes provide a realistic dark matter candidate, with a mass of the order of 1 TeV, which will be probed by direct dark matter detection experiments in the near future.
