Breakdown of the impulse approximation and its consequences: the low-Q^2 problem
Creators: name: Ankowski, Artur M.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Neutrino scattering data and the standard calculations of the cross section show a discrepancy in the low-Q^2 (four-momentum transfer squared) region. The calculations rely on the assumption, called the impulse approximation, that the nucleus the neutrino scatters off can be described as a collection of independent nucleons and therefore only one nucleon takes part in the interaction. It is known from electron scattering that such picture is valid only when transferred momentum |q|>400 MeV/c. For lower |q|'s, the nucleus is probed with a lower spatial resolution and a few nucleons are involved in the scattering, so the use of the impulse approximation is unjustified. It means that the standard calculations of the cross sections are unreliable for |q|<400 MeV/c. I show that the contribution of low-momentum interactions to the quasielastic neutrino cross section cannot be reduced below ~19% by any selection of the beam energy in the few-GeV region. Moreover, low-Q^2 neutrino events happen only when transferred momentum is low too. Hence the discrepancy in the low-Q^2 region is caused by the inappropriate description of low-|q| interactions in the models commonly used in Monte Carlo simulations.

Statistical epidemiology of gonorrhoea in the United Kingdom
Creators: name: Whittles, Lilith K.
Publisher: name: Imperial College London
Year: 2018

description: Gonorrhoea is one of the most common sexually-transmitted bacterial infections in the UK. Almost half of the 44,000 cases recorded in 2017 occurred in men who have sex with men (MSM). The bacterium has developed resistance to each first-line antibiotic in turn, such that clinicians are running out of treatment options. We need to make informed decisions to combat antibiotic-resistant gonorrhoea, but are hampered by a lack of understanding in key areas, including: the dynamics of how resistance spreads, its relationship with antibiotic prescribing, and the potential impact of interventions, such as vaccination. To improve understanding of the fitness benefits and costs of antibiotic resistance to inform control policy and planning, I developed a mathematical model that captures the dynamics of cefixime resistance observed in the UK from 2008-2015. Cefixime was abandoned because of rising resistance, but I found that the fitness cost is such that resistance levels have since dropped, and reintroduction could be considered to treat a minority of cases. Both the dynamic forming and breaking of partnerships and heterogeneity in sexual behaviours affect how gonorrhoea outbreaks spread. To assess the implications of network structure on transmission dynamics, I developed a stochastic simulation framework that produces dynamic sexual networks calibrated to real-world data. I used the model to improve estimates of the generation-time and offspring distributions, and to predict the impact of a range of interventions, including vaccination. Vaccination against gonorrhoea could extend the useful life of our first-line therapies. Although no gonococcus-specific vaccine exists, there is evidence that a meningococcal vaccine, MeNZB, offers partial protection. I investigated how efficacious and long-lasting a vaccine would be needed to control antibiotic resistance, and found that even partially-effective vaccines show great promise. In particular, MeNZB could have a substantial impact on incidence, even if gonorrhoea becomes untreatable.
title: Determination of Optimum Quality in Ground Turkey Formulation
Creators: name: Chongdarakul, Juntip
Publisher: name: Utah State University
Year: 1974

description: Ground turkey samples were prepared with different fat levels, fat types, percent mechanically deboned meat and grind. All samples were analyzed at three different time-intervals. Samples were evaluated by chemical, sensory, and physical measurements, in term of stability, water content, fat content, press fluid, water loss, flavor, texture, and hedonic values. Significant differences were determined by analysis of variance.
Coarse ground (5/8") samples showed significantly higher TBA numbers, fat content, total loss, and juiciness. Water content, flavor scores, amount of press fluid, texture scores, and hedonic scores were lower when compared to the fine and medium ground samples.
Results of adding different percents deboned meat showed that TBA number and water content increased as the percent deboned meat increased. Decreases in flavor score, fat content, press fluid, total loss, and juiciness were obtained with increased percent deboned meats. However, sensory panelists preferred the samples with 10 percent added deboned meat to other deboned levels regardless of grind.
The results of adding different types and levels of fat indicated that samples containing vegetable fat had the lowest TBA numbers while the samples containing beef fat showed the highest value. As the level of fat and length of storage increased, TBA numbers increased significantly.
Sensory panel scores for juiciness and press fluid of the individual treatments fluctuated with level of added fat. As the fat levels were increased, juiciness scores and the amount of press fluids increased significantly.
Loss due to cooking and thawing was highest for samples containing vegetable fat and lowest for samples containing pork fat. An increase in total loss was observed as fat levels were increased. Samples with turkey and beef fat received the high texture scores. The low texture scores appeared as the level of any type of fat increased. All samples with 10 percent added fat received the highest s core for overall acceptability.
Orlan/Deleuze : coporeal/(in)corporeal
Creators: name: Moss, SE
Publisher: name: University Of Tasmania
Year: 2023

description: \Orlan I Deleuze\" comprises an introduction three chapters and a conclusion. The introduction surveys the French performance-artist Orlan who for the past thirty-five years has worked with the materiality of her own body to create a \"body\" of contemporary art work which has provoked the art world in a number of ways. In the 1990's Orlan combined elements and recurring themes from her past work to create a \"performance for the future\" titled The Reincarnation of Saint Or/an. This series provides a recurring focus throughout the dissertation. Commentators have invoked a diversity of discursive frameworks to explicate the multiple elements of Orlan's Reincarnation. However the failure of these critiques to provide a sustained reading remains unsatisfying. The introduction signals that the conceptual schemas of Gilles Deleuze and Felix Guattari will be activated in order to clear the ground of metaphysical concepts so that the affect of Orlan's corporeal practice can be apprehended in a sustained way. Chapter One situates Orlan as a concept-event intervening against the problem of a representational culture that portrays the body as ideal and seamless. Spinoza's formulation \"What can a body do?\" provides an informing question that enables a way of engaging with Orlan's corporeal strategy. This chapter modulates Orlan's art through a Deleuzean framework and discusses how the event of Orlan's non-face counter-actualises the designation Woman as Face. Chapter Two surveys Deleuze--Guattari's concepts offaciality and the incorporeal transformation effectuated by order-words. The alliance of the market and the socius in sustaining and circulating desired images of the face is also identified. The rules of the assemblage are applied to explicate Orlan's practice and the chapter presents an argument that Orlan enacts a becoming-minor of the face. Chapter Three situates Orlan's multi-medial practice as \"cinematic\" and approaches Deleuze's concept of the time-image as co-extensive with Orlan's corporeal art through the revelation of the unthought within thought. The spectatorial responses to the reception and viewing of Orlan's mediatised performances are also surveyed. The conclusion considers the ontological premise of contemporary art. In response to the uncomprehending and negative reactions to Orlan's project three concrete rules are presented for contemporary art."
Homeomorphisms of Stone-Čech compactifications

description: The set of all compactifications, K(X) of a locally compact, non-compact space X form a complete lattice with βX, the Stone-Čech compactification of X as its largest element, and αX, the one-point compactification of X as its smallest element. For any two locally compact, non-compact spaces X,Y, the lattices K(X), K(Y) are isomorphic if and only if βX - X and βY - Y are homeomorphic. βN is the Stone-Čech compactification of the countable infinite discrete space N. There is an isomorphism between the group of all homeomorphisms of βN and the group of all permutations of N; so βN has c homeomorphisms. The space N* =βN - N has 2c homeomorphisms. The cardinality of the set of orbits of the group of homeomorphisms of N* onto N* is 2c . If f is a homeomorphism of βN into itself, then Pk , the set of all k-periodic points of f is the closure of PkՈN in βN.

description: The density of dark matter near the Sun is important for experiments hunting for dark matter particles in the laboratory, and for constraining the local shape of the Milky Way's dark matter halo. Estimates to date have typically assumed that the Milky Way's stellar disc is axisymmetric and in a steady-state. Yet the Milky Way disc is neither, exhibiting prominent spiral arms and a bar, and vertical and radial oscillations. We assess the impact of these assumptions on determinations of the local dark matter density by applying a free-form, steady-state, Jeans method to two different N-body simulations of Milky Way-like galaxies. In one, the galaxy has experienced an ancient major merger, similar to the hypothesized Gaia-Sausage-Enceladus; in the other, the galaxy is perturbed more recently by the repeated passage and slow merger of a Sagittarius-like dwarf galaxy. We assess the impact of each of the terms in the Jeans-Poisson equations on our ability to correctly extract the local dark matter density from the simulated data. We find that common approximations employed in the literature - axisymmetry and a locally flat rotation curve - can lead to significant systematic errors of up to a factor ~1.5 in the recovered surface mass density ~2kpc above the disc plane, implying a fractional error on the local dark matter density of order unity. However, once we add in the tilt term and the rotation curve term in our models, we obtain an unbiased estimate, consistent with the true value within our 95% confidence intervals for realistic 20% uncertainties on the baryonic surface density of the disc. Other terms - the axial tilt, 2:nd Poisson and time dependent terms - contribute less than 10% to the local dark matter density (given current data) and can be safely neglected for now. In the future, as more data become available, these terms will need to be included in the analysis.

Stories lived, told, and shared : Tasmanian drama teachers' narratives of identity
Creators: name: Moss, T
Publisher: name: University Of Tasmania
Year: 2023

description: This project aimed to first examine and problematise our existing knowledge of what it might mean to be a drama teacher, and second, to employ innovative arts-based methods of research in order to explore how drama teachers themselves understand and describe their experiences. Of prime importance in this work was the connection between one of the fundamental purposes of qualitative research, and of artistic inquiry - that is, to encourage the reader/audience to engage in an act of educative transgression, questioning and examining their own assumptions about important experiences or phenomena. Instead of attempting to 'capture' truth or meaning through measurement and objectification, this thesis sought to place the elements of research - reading, doing, and writing- in an aesthetic dialogue, in order to promote the development of multiple meanings. While there are established bodies of research literature in the areas of both personal identity and teachers' lives and careers, there is a scarcity of research that attempts to engage with the connections between these two areas, particularly in terms of how teachers themselves understand and make sense of their lives. This project sought to address this issue by working closely with six drama teachers, exploring through a series of interviews the consequences of their life experiences (both within and outside the classroom) in terms of how they saw themselves as teachers, and as individuals more broadly. One of the most significant findings reported in this thesis is that often, teachers do not perceive any separation between what is personal, and what is professional. This raises significant questions about the broader processes and purposes of educational research. As a dialogue, there was opportunity within the project for telling, as well as listening. In the interpretive phase of this project, three 'tellings' took place. The first telling was the interpretation of the stories told by each teacher. By reading and writing about each participant's life within the aesthetic spaces of the text and the interview, these stories were included in an interpretive dialogue. In the second telling, sharing this new story - our story - with the participants during the interviewing and writing processes, this dialogue was extended. In the third telling, the reader is invited to join in the interpretive journey, to add their own voice to the newly developing conversation about the interactions between our experiences and identities, in and out of the classroom.

description: This article provides us with a unifying classification of the conformal infinitesimal symmetries of non-relativistic Newton-Cartan spacetime. The Lie algebras of non-relativistic conformal transformations are introduced via the Galilei structure. They form a family of infinite-dimensional Lie algebras labeled by a rational "dynamical exponent", $z$. The Schrödinger-Virasoro algebra of Henkel et al. corresponds to $z=2$. Viewed as projective Newton-Cartan symmetries, they yield, for timelike geodesics, the usual Schrödinger Lie algebra, for which z=2. For lightlike geodesics, they yield, in turn, the Conformal Galilean Algebra (CGA) and Lukierski, Stichel and Zakrzewski [alias "$\alt$" of Henkel], with $z=1$. Physical systems realizing these symmetries include, e.g., classical systems of massive, and massless non-relativistic particles, and also hydrodynamics, as well as Galilean electromagnetism.

Information content of the differences in the charge radii of mirror nuclei

name: Nazarewicz, Witold
Publisher: name: arXiv
Year: 2022
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Differences in the charge radii of mirror nuclei have been recently suggested to contain information on the slope of the symmetry energy L. To test this hypothesis, we perform statistical correlation analysis using quantified energy density functionals that are consistent with our previous knowledge on global nuclear observables such as binding energies and charge radii. We conclude that the difference in charge radii between a mirror pair, R_mir, is an inferior isovector indicator compared to other observables, such at the neutron skin or electric dipole polarizability. In particular, this quantity correlates poorly with both the neutron skin and L. We demonstrate that R_mir is influenced by pairing correlations in the presence of low-lying proton continuum in the proton-rich mirror-partner nucleus. Considering the large theoretical uncertainties on R_mir, we conclude that the precise data on mirror charge radii cannot provide a stringent constraint on L.

Three studies in forest ecology.
Creators: name: Mount, A. B.
Publisher: name: University Of Tasmania
Year: 2023

description: The first part of this thesis is based on observations made in the forest and a discussion of the place of fire in the ecology. It is concluded that there has been ecological equilibrium for several thousand years except in areas where man's pattern of behaviour has recently changed. It is argued that this equilibrium is dynamic and that it takes the form of \fire-cycles\". The second part deals with some experiments carried out during the period 1957-61. The third part discusses regeneration surveys in Tasmania and other parts of the world and then proposes a new factor of heterogeneity \"h\" which appears to have several advantages over existing factors."

description: Molecular motors convert chemical energy into mechanical work while operating in an environment dominated by Brownian motion. The aim of this paper is to explore the flow of energy between the molecular motors and its surroundings, in particular, its efficiency. Based on the Fokker-Planck equation with either $N$ or infinite chemical states, we find that the energy efficiency of the molecular motors, whether the Stokes efficiency or the usual thermodynamic efficiency, is strictly bounded by 1, because of the dissipation of the energy in both the overdamped surroundings and in the process of the chemical reaction.

Indeed, it is linearly related to the temperature and number density gradients and not to the acceleration as the so-called "first order in the gradients theories" contend. Here we calculate explicitly the ensuing transport coefficients and compare them with the results obtained by other authors.

Weak itinerant ferromagnetic order is detected by a spontaneous muon spin precession frequency below the Curie temperature $T_C = 3$ K. The $μ^+$ precession frequency persists below the bulk superconducting transition temperature $T_{sc} = 0.5$ K, where it measures a local magnetic field $B_{loc} = 0.015$ T. The amplitude of the $μ$SR signal provides unambiguous proof for ferromagnetism present in the whole sample volume. We conclude ferromagnetism coexists with superconductivity on the microscopic scale.

title: Procedure for Measuring Residual Endothia Parasitica Protease in Curd and Whey From Freshly Coagulated Milk
Creators: name: Patel, Raman B.
Publisher: name: Utah State University
Year: 1974

description: Test procedures were developed for measuring the residual milk clotting activity of a protease produced by Endothia parasitica in curd and viii whey separated from freshly coagulated milk. A substrate was prepared by reconstituting 6 g low heat nonfat dry milk in 500 ml buffer containing 50 ml 0.5M cacodylic acid, 50 ml 0.2M CaCl2 , 30 ml 0.2M triethanolamine and 370 ml double distilled water. The substrate was stored at 2 to 4 C for 20 hours before use. Two milliliters of whey or supernatant from centrifuged curd-water slurries were inoculated into 25 ml of substrate at 30 C and the coagulation time noted, and compared with that produced by a known dilution of a standard enzyme solution.
Endothia parasitica curd formed at pH 6.7 contained 45 per cent of the enzyme activity added to 454 g milk hut when formed at pH 5.2 the curd contained only 25 per cent. ix The recovery of Endothia parasitica protease in curd was made by preparing a 1:5 curd-water slurry, adjusting to pH 5.4, filtering and testing the filterate.

The algorithm readily generalizes to situations, where the additional observer uses three measurement settings. There, each inequality involving the additional party is constructed from three inequalities with this party excluded. With this generalization at hand, we construct and analyze new symmetric inequalities for four observers and three experimental settings per observer.

description: The quasi-classical method of deriving Hawking radiation under the consideration of canonical invariance is investigated. We find that the horizon should be regarded as a two-way barrier and the ingoing amplitude should be calculated according to the negative energy particles tunneling into the black hole because of the whole space-time interchange and thus the standard Hawking temperature is recovered. We also discuss the advantage of the Painlevé coordinates in Hawking radiation as tunneling.
Properties of eigenvalues of singular second order elliptic operators

Publisher: name: University of British Columbia
Year: 2011

description: This thesis investigates the properties of the L₂-eigenvalues of singular, elliptic, second order operators, primarily the operator L defined by [formula omitted]. Here the "potential function", V(x), is such that [formula omitted] is a norm on [formula omitted] being the usual norm in the Sobolev space W¹̕²(G) and [formula omitted] is the completion of [formula omitted] in the metric from this norm, identified with a subset L₂(G) ; Δ is the Laplacian and G is an arbitrary open domain of E[superscript n] . Several sufficient conditions are given on V and on G in order that L have spectrum satisfying [formula omitted] , for some real number [formula omitted] denote the spectrum and point spectrum of L , respectively). The properties of these lower eigenvalues are investigated by examining the eigenvalues of a coercive bilinear form corresponding to the operator. Such a form B , having domain [symbol omitted] , say, is defined to have eigenvalueλє¢ with corresponding eigenfunction [symbols omitted] if B[u,f] = λ (u,f) for all f є [symbol omitted] . Variational properties are discussed in detail; In particular, a condition is given which ensures that the numbers sup inf B[u,u] (the sup and inf being over appropriate sets involving [symbol omitted] and n ) are eigenvalues of B . These properties are applied to L to generalize the well-known classical property (G bounded) of monotonic dependence of the eigenvalues on the underlying domain G : G [symbol omitted] G* implies [formula omitted] for corresponding eigenvalues, with strict inclusion implying strict inequality. A few miscellaneous properties of the eigenvalues and eigenfunctions then follow from this dependence.

description: We develop a 2D inclined rotating disc model, which we apply to the stellar velocity maps of 1862 galaxies taken from the MaNGA survey (SDSS public Data Release 15). We use a random forest classifier to identify the kinematic parameters that are most connected to galaxy quenching. We find that kinematic parameters that relate predominantly to the disc (such as the mean rotational velocity) and parameters that characterise whether a galaxy is rotation- or dispersion-dominated (such as the ratio of rotational velocity to velocity dispersion) are not fundamentally linked to the quenching of star formation. Instead, we find overwhelmingly that it is the absolute level of velocity dispersion (a property that relates primarily to a galaxy's bulge/spheroidal component) that is most important for separating star forming and quenched galaxies. Furthermore, a partial correlation analysis shows that many commonly discussed correlations between galaxy properties and quenching are spurious, and that the fundamental correlation is between quenching and velocity dispersion. In particular, we find that at fixed velocity dispersion, there is only a very weak dependence of quenching on the disc properties, whereby more discy galaxies are slightly more likely to be forming stars. By invoking the tight relationship between black hole mass and velocity dispersion, and noting that black hole mass traces the total energy released by AGN, we argue that these data support a scenario in which quenching occurs by preventive feedback from AGN. The kinematic measurements from this work are publicly available.

Year: 1974

description: A linear diffusion test in sedimentation tubes filled with caseinagar gel successfully measured milk clotting enzymes at concentrations of 10-4 to 1 X 10-l rennin units/ml with 95% accuracy. Diffusion rates were unaffected by diluting enzyme samples with whey, 3% NaCl, and water, The distribution of rennet, porcine pepsin, mucor pusillus var Lindt (MP) protease, and rennet-pepsin mixtures between curd and whey was determined on milk coagulated at pH 5.2, 6.0, 6.4, and 6.6. The procedure accounted for 100 + 7% of the added enzymes. The distribution of rennet was pH dependent with 31% and 72% in curd and whey respectively at pH 6.6, and 864 and 174 respectively at pH 5.2. The distribution of MP protease was independent of pH with approximately 154 and 85% in the curd and whey at all pH values. Pepsin behaved similar to rennet but was unstable above pH 6.0. During Cheddar cheese making, 7% and 58% of the original rennet, 6% and 93% of the original MP protease, and 5% and 17% of the original rennet-pepsin mix was active in the curd and whey respectively at dipping. After overnight pressing, 6% of the rennet, 3% of MP protease, and 4% of the rennet-pepsin mix remained active in the cheese. At dipping only 9% of the original pepsin was detected in the whey. Pepsin was unstable at pH values used to release the enzyme from the curd and could not be quantitated.

description: We consider the dynamics of the domain-wall kink soliton, in particular we study the zero mode of translation. In the infinitely-thin kink limit, we show that the zero mode is almost completely frozen out, the only remnant being a dynamically constrained four-dimensional mode of a single but arbitrary frequency. In relation to this result, we show that the usual mode expansion for dealing with zero modes -- implicit collective coordinates -- is not in fact a completely general expansion, and that one must use instead a traditional generalised Fourier analysis.

description: We present Hubble Space Telescope (HST) photometric results for NGC 6402, a highly reddened very luminous Galactic globular cluster (GC). Recent spectroscopic observations of its red giant stars have shown a quite peculiar behavior in the chemistry of its multiple populations. These results have prompted UV and optical HST observations aimed at obtaining the cluster's "Chromosome map" (ChM), an efficient tool to classify GCs and characterize their multiple populations. We find that the discontinuity in the abundance distributions of O, Mg, Al and Na inferred from spectroscopy is more nuanced in the ChM, which is mostly sensitive to nitrogen. Nevertheless, photometry in optical bands reveals a double main sequence, indicating a discontinuity in the helium content of the populations. The population with the largest chemical anomalies (extreme) peaks at a helium mass fraction Y~0.31. This helium content is consistent with results from the analysis of the distribution of horizontal-branch stars and the spectrophotometry of the red giants. The ChM and the color magnitude diagrams are compared with those in NGC 2808, a prototype GC with helium abundances up to Y > 0.35, and both confirm that NGC 6402 does not host stellar populations with such extreme helium content. Further, the ChM reveals the presence of a group of stars with larger metallicity, thus indicating that NGC 6402 is a Type II cluster. The modalities of formation of the multiple populations in NGC 6402 are briefly surveyed, with main attention on the Asymptotic Giant Branch and Supermassive star models, and on possible clusters' merging.

Creators: name: Newman, Ian A

description: Measurements of electric potential differences between points on the surface of etiolated Avena coleoptiles have been made with a reliable, new technique. These show that an electric wave moves down an intact coleoptile when its apex is illuminated, or down a decapitated coleoptile when indole acetic acid (IAA) is applied to its cut top. It is postulated that auxin-requiring electric oscillators in the coleoptile are the source of the wave and that they are synchron ised by a sudden change in the stream of auxin moving down from the top. It is shown that the electric wave provides a useful technique for studying auxin transport under altered environmental or metabolic conditions. Carbon 14 tracer studies confirm the suggestion, arising from the electric measurements, that IAA, moving from a source on the top of a decapitated coleoptile, possesses a definite front moving at constant speed. This speed depends on the ambient temperature. Graphs have been obtained relating concentration of mobile and immobilised 14C-IAA to both distance and time after application of the IAA at several concentrations to the top of the decapitated coleoptile. At the lowest concentrations of IAA applied the graphs of concentration against distance are linear from near the top of the coleoptile to the front of the IAA stream. Linearity exists in the region of the f'ront even with concentrations above 0.4 mgm/litre applied. Further experiments show that there is much 14c-IAA in the coleoptile that is mobile but is not actually moving with the speed of the front of the stream, so that the very concept of a \stream\" to describe IAA transport must be questioned. Effects of IAA application for a short time are investigated as is the effect of tri-iodobenzoic acid on IAA transport. Design construction and operation of an inexpensive reliable low-background G-M counting system developed specially for the 14c tracer experiments is described. A mathematical treatment of the results shows their inter relationships their dependence on the rate of uptake of IAA from the source into the transport system and on the rate of immobilisation of IAA in the coleoptile. Both the rate of uptake and the rate of immobil isation increase with time. The treatment shows also how results of other workers on the export of IAA from the base of a coleoptile section can be predicted from the present work. Theoretical models of auxin transport are discussed in the light of the results and analysis. It is clear that diffusion cannot play a major part in the normal transport of auxin in the coleoptile and that each cell must pass on to the next nearly all the auxin that it initially receives. A survey of the literature on auxin transport up to 1965 is presented as an appendix."
Investigating the critical properties of beyond-QCD theories using Monte Carlo Renormalization Group matching

description: Monte Carlo Renormalization Group (MCRG) methods were designed to study the non-perturbative phase structure and critical behavior of statistical systems and quantum field theories. I adopt the 2-lattice matching method used extensively in the 1980's and show how it can be used to predict the existence of non-perturbative fixed points and their related critical exponents in many flavor SU(3) gauge theories. This work serves to test the method and I study relatively well understood systems: the $N_f=0$, 4 and 16 flavor models. The pure gauge and $N_f=4$ systems are confining and chirally broken and the MCRG method can predict their bare step scaling functions. Results for the $N_f=16$ model indicate the existence of an infrared fixed point with nearly marginal gauge coupling. I present preliminary results for the scaling dimension of the mass at this new fixed point.

title: Effects of X-Ray Induced Achlorhdria on the Utilization of Dietary Calcium and Iron From Different Salts by Rats
Creators: name: Holbrook, Reid Scott
Publisher: name: Utah State University
Year: 1974

description: Dietary calcium has been classified as one of the minerals frequently limiting in the American diet (FAO, 1962) . Bone demineralization has been observed as a result of calcium deficient diets (Salomon et al., 1972), partial gastrectomies (Eddy, 1971) and inadequate hormonal balance (Albright et al., 1948). Although bone demineralization, or osteoporosis, has been attributed to many factors, the interrelationship of gastric acidity and the utilization of dietary calcium may be a key to the etiology of osteoporosis.
Eighty weanling male albino rats were divided into eight groups. All animals had their stomachs exposed through a mid-line incision. Control rats were sham-operated while the treatment animals had their stomachs X-irradiated to destroy the secretory cells. Four diets were prepared containing calcium carbonate, calcium chloride, tri-calcium phosphate or calcium gluconate as calcium sources. For a three-week experimental period, ten control and ten X-irradiated rats were fed each diet.
In vitro data suggests that the solubility of each calcium salt, except calcium gluconate, increased in an acid media. Saturated viii ix solutions of calcium carbonate and tri-calcium phosphate had low quantities of calcium ion in solution in neutral pH's, but as the acidity was changed from pH 4 to pH 3 the calcium ion concentration increased as much as eight times. This demonstrates that the presence of acid with insoluble forms of calcium salts will generally increase calcium ion concentration in solution.
All X-irradiated animals had an average fasting gastric pH of over 6, while the control rats averaged pH 2.5. The calcium absorption data demonstrates that X-irradiated rats fed diets containing soluble calcium salts (calcium chloride, 18.5 percent and calcium gluconate, 25.13 percent) had increased absorption values over those fed diets containing calcium salts of low solubility (calcium carbonate, 12.94 percent and tri-calcium phosphate, -7.06 percent).
Femur strength and bone calcium data reflected similar evidence. Both femur strength and bone calcium of the X-irradiated rats fed the less soluble forms of calcium salt were significantly lower than the controls, while X-irradiated rats fed the more soluble forms of calcium had femur strength and bone calcium similar to the controls.
Achlorhydric, or X-irradiated, animals were observed to have decreased iron stores in comparison with the control rats. Hemoglobin levels, liver iron and iron absorption were all significantly reduced in the x-irradiated animals.
From the results of these experiments, it is apparent that gastric acidity and the solubility of the dietary calcium source play an important role in the utilization of calcium.

description: Analysis of pulsar timing data-sets may provide the first direct detection of gravitational waves. This paper, the third in a series describing the mathematical framework implemented into the tempo2 pulsar timing package, reports on using tempo2 to simulate the timing residuals induced by gravitational waves. The tempo2 simulations can be used to provide upper bounds on the amplitude of an isotropic, stochastic, gravitational wave background in our Galaxy and to determine the sensitivity of a given pulsar timing experiment to individual, supermassive, binary black hole systems.

description: Two metrics $g $ and $\bar g$ are geodesically equivalent, if they share the same (unparameterized) geodesics. We introduce two constructions that allow one to reduce many natural problems related to geodesically equivalent metrics, such as the classification of local normal forms and the Lie problem (the description of projective vector fields), to the case when the (1,1)-tensor $G^i_j:= g^{ik} \bar g_{kj}$ has one real eigenvalue, or two complex conjugate eigenvalues, and give first applications. As a part of the proof of the main result, we generalize Topalov-Sinjukov (hierarchy) Theorem for pseudo-Riemannian metrics

description: It is shown that the equation of motion of the one-particle Green function of an interacting many-electron system is governed by a multiplicative time-dependent exchange-correlation potential, which is the Coulomb potential of a time-dependent exchange-correlation hole. This exchange-correlation hole fulfills a sum rule, a generalization of the well-known sum rule of the static exchange-correlation hole. It is envisaged that the proposed formalism may provide an alternative route for calculating the Green function by finding a suitable approximation for the exchange-correlation hole or potential based on, e.g., a local-density approximation.

description: We study the representation theory of the quantum Teichmueller space when going to infinity in the classical Teichmueller space. The geometric ingredients are the extension of Thurston's shear coordinates to the augmented Teichmueller space and the study of the Weil-Petersson Poisson structure for this extension. The result is analogous to the factorization rule found in conformal field theory.
