description: The angular momentum (AM) content of massive stellar cores helps to determine the natal spin rates of neutron stars and black holes. Asteroseismic measurements of low-mass stars have proven that stellar cores rotate slower than predicted by most prior work, so revised models are necessary. In this work, we apply an updated AM transport model based on the Tayler instability to massive helium stars in close binaries, in which tidal spin-up can greatly increase the star's AM. Consistent with prior work, these stars can produce highly spinning black holes upon core-collapse if the orbital period is less than $P_{\rm orb} \lesssim \! 1 \, {\rm day}$. For neutron stars, we predict a strong correlation between the pre-explosion mass and the neutron star rotation rate, with millisecond periods ($P_{\rm NS} \lesssim 5 \, {\rm ms}$) only achievable for massive ($M \gtrsim 10 \, M_\odot$) helium stars in tight ($P_{\rm orb} \lesssim 1 \, {\rm day}$) binaries. Finally, we discuss our models in relation to type Ib/c supernovae, superluminous supernove, gamma-ray bursts, and LIGO measurements of black hole spins. Our models are roughly consistent with the rates and energetics of these phenomena, with the exception of broad-lined Ic supernovae, whose high rates and ejecta energies are difficult to explain.

Creators: name: Zhang, Yunxin
Publisher: name: arXiv
Year: 2008
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: In this research, the totally asymmetric exclusion process without particle number conservation is discussed. Based on the mean field approximation and the Rankine-Hugoniot condition, the necessary and sufficient conditions of the existence of the domain wall have been obtained. Moreover, the properties of the domain wall, including the location and height, have been studied theoretically. All the theoretical results are demonstrated by the computer simulations.
Potential flow theory for airfoil spoilers
Creators: name: Jandali, Tarek
Publisher: name: University of British Columbia
Year: 2011

description: A theory is presented for the calculation of the pressure distribution and lift for arbitrary thick airfoils fitted with normal upper surface spoilers in two dimensional incompressible flow. Airfoil shape and angle of attack and spoiler location and height are arbitrary and unrestricted. The theory uses a sequence of conformal transformations from a basic flow past a circle, with one or two sources on that part of the circle corresponding to the surface of the airfoil and spoiler exposed to the wake. The flow inside the separating streamlines is ignored, and the upper surface pressure downstream of the spoiler is taken as an empirical parameter, assumed constant. The sources in the wake permit satisfaction of Kutta conditions with the desired pressure at the spoiler tip and airfoil trailing edge. Features of the theory include good prediction of loading distribution, a finite wake width and a pressure distribution on the separating streamlines decreasing asymptotically towards the free stream value at infinity. The theoretical predictions are compared with lift and pressure measurements on a Joukowsky airfoil of 11% thickness and 2.L\% camber, and with lift measurements on a 14% thick Clark Y airfoil. Both airfoils were tested through a range of angle of attack with spoilers of 5 and 10% chord height, each at several locations. Good agreement is found.

description: In September 2021 the magnetar SGR J1935+2154 entered a stage of burst/flaring activity in the hard X-ray band. On September 10, 2021 we observed SGR J1935+2154 with the fiber-fed fast optical photon counter IFI+Iqueye, mounted at the 1.22 m Galileo telescope in Asiago. During one of the IFI+Iqueye observing windows a hard X-ray burst was detected with the Fermi Gamma-ray Burst Monitor. We performed a search for any significant increase in the count rate on the 1-s, 10-ms and 1-ms binned IFI+Iqueye light curves around the time of the Fermi burst. No significant peak was detected with a significance above 3$σ$ in an interval of $\pm$90 s around the burst. Correcting for interstellar extinction ($A_V \simeq 5.8$ mag), the IFI+Iqueye upper limits to any possible optical burst from SGR J1935+2154 are $V=10.1$ mag, $V=7.2$ mag and $V=5.8$ mag for the 1-s, 10-ms and 1-ms binned light curves, respectively. The corresponding extinction corrected upper limits to the fluence (specific fluence) are $3.1 \times 10^{-10}$ erg cm$^{-2}$ (0.35 Jy s), $4.2 \times 10^{-11}$ erg cm$^{-2}$ (4.8 Jy $\cdot$ 10 ms), and $1.6 \times 10^{-11}$ erg cm$^{-2}$ (17.9 Jy ms), orders of magnitude deeper than any previous simultaneous optical limit on a magnetar burst. The IFI+Iqueye measurement can also place a more stringent constraint to the spectral index of the optical to hard X-ray fluence of SGR J1935+2154, implying a spectrum steeper than $ν^{0.64}$. Fast optical timing observations of bursts associated with radio emission have then the potential to yield a detection.

title: The Influence of a Nutrition Education Program on Preschool Children
Creators: name: Houston, Nida Diane
Publisher: name: Utah State University
Year: 1975

description: A study on the influence of nutrition education experiences was conducted in the Child Development Preschool Laboratory at Southern Utah State College in Cedar City, Utah, with thirty-two preschool children. Sixteen of the children were exposed to nutrition experiences through food activities and stories.
It was found that the sixteen children who were involved in the fifteen nutrition experiences significantly increased their knowledge of nutrition concepts and further modified their own personal food choices. The control group, which was not exposed to nutrition activities, made no significant change in knowledge of nutrition concepts and no modification of personal food choices.
The findings also indicated that there was no significant difference between girls and boys in their ability to learn nutrition concepts. However, there appeared to be some slight sex differences in the modification of personal food choices.
title: Persistence of Mucor Miehei Protease in Cheddar Cheese and Pasteurized Whey and its Effect on Sterile Milk Products
Creators: name: Thunell, Randall Kirk
Publisher: name: Utah State University
Year: 1977

description: Whey from a commercial cheese plant, taken at draining on five separate days, from cheese made with a Mucor miehei coagulant was cooled within 1 h to 4 C. Portions were adjusted from pH 4.2 to 6.4 at .2 pH intervals and subjected to HTST pasteurization at 73.9, 76.6, and 79.5 C for 25 sec. Milk clotting activity in whey was determined before and after pasteurization. Resistance to heat in-activation increased with decreasing pH. All measurable activity was destroyed above pH 5.4 by pasteurization at 79.5 C, above pH 5.8 at 76.6 C and above pH 6.0 at 73.9 C.
Milk clotting activity in Cheddar cheese mad with Mucor miehei remained unchanged for 26 weeks.
Four commercial sterile liquid-milk-based consisting of infant formula, concentrated infant formula, nutritionally complete food, and diet food was aseptically inoculated with sterile Mucor miehei protease solutions to concentrations ranging from 5 x 10-3 to 1 x 10-7 chymosin units/ml of product. The samples were stored at 30 C. After 20 weeks there was no change in the nutritionally complete food. The diet food showed slight whey separation and thickening at 1 x 10-4 CU/ml and coagulation at higher concentrations. The infant formula showed definite whey separation and thickening at 1 x 10-4 CU/ml and coagulation and higher concentrations. The concentrated infant formula showed visible thickening at 1 x 10-3 CU/ml and coagulation at higher concentrations.

Technical demands of selected contemporary works for violin
Creators: name: Ho, ACK
Publisher: name: University Of Tasmania
Year: 2023

description: This exegesis provides an overview of selected contemporary works composed for the violin over the past four decades. It elaborates on the practical demonstration and interpretation of contemporary composition, as well as some of the ideas and innovations that have shaped performance practice. Live and recorded performances and a web-based demonstration are used to illustrate a variety of technical and expressive demands placed on the performer of the selected violin repertoire. Three recorded doctoral recitals demonstrate links between traditional and contemporary violin music. The intention of the recitals is to show the audience that contemporary violin music is accessible to both player and audience. The ideas that underpin this music are explored in the written component of the exegesis. Some of the issues facing performance of contemporary music are addressed, with particular emphasis on the influence exerted by the experimental movement and the indeterminist style. The intention is to consider music and musical practice that pushes the boundaries of the traditional classical paradigm. Works studied in depth are by composers Luciano Berio, Robert Davidson, Damien Ricketson and Clarence Mak.

title: A Field Study in the Use of Dietary and Urinary Variables in Determining Osteoporosis in Elderly People
Creators: name: Osborn, Jane Steger
Publisher: name: Utah State University
Year: 1977

description: Three-day dietary records were analyzed for nutrient content and 24 hour urine samples were analyzed for calcium, phosphorous, total nitrogen, and free alpha-amino nitrogen for 210 elderly people. Dietaries and urine samples were collected twice, October and March at five month intervals, for each subject. Increases were found in both dietary intake and urinary components October to March. Based on a criteria of high dietary protein, low dietary calcium, high urinary nitrogen and low calcium, 23 subjects were selected as osteoporotic and and 25 were selected as non-osteoporotic. This method of prediction was not supported by radiological evaluations.
Bone density and percent cortical area of the second metacarpal and the trabecular pattern of the femoral head were evaluated for each subject. A negative correlation of trabecular pattern with age indicated a general loss of bone with age.
Decreased percent cortical area was the most consistent bone phenomena associated with osteoporosis. No significant difference was found between sexes in any of the radiological analysis.
The osteoporotic condition is more closely associated with a loss of bone quantity than decreased bone quality. As yet, osteoporosis is not associated with specific nutrient(s) consumption or urinary excretion(s).

description: The structure of nuclei around the neutron-rich nucleus 132Sn is of particular interest due to the vicinity of the Z = 50 and N = 82 shell closures and the r-process nucleosynthetic path. Four states in 131Sn with a strong single-particle-like component have previously been studied via the (d,p) reaction, with limited excitation energy resolution. The 130Sn(9Be,8Be)131Sn and 130Sn(13C,12C)131Sn single-neutron transfer reactions were performed in inverse kinematics at the Holifield Radioactive Ion Beam Facility using particle-gamma coincidence spectroscopy. The uncertainties in the energies of the single-particle-like states have been reduced by more than an order of magnitude using the energies of gamma rays. The previous tentative Jpi values have been confirmed. Decays from high-spin states in 131Sn have been observed following transfer on the isomeric component of the 130Sn beam. The improved energies and confirmed spin-parities of the p-wave states important to the r-process lead to direct-semidirect cross-sections for neutron capture on the ground state of 130Sn at 30 keV that are in agreement with previous analyses. A similar assessment of the impact of neutron-transfer on the isomer would require significant nuclear structure and reaction theory input. There are few measurements of transfer reaction on isomers, and this is the first on an isomer in the 132Sn region.

description: Moraxella bovis is considered to be the main causative agent of infectious bovine keratoconjunctivitis (IBK), commonly known as pinkeye1 2. IBK has been reproduced with M. bovis organisms alone3 or in combination with other enhancing factors4 8. Numerous attempts have been made to produce a M. bovis vaccine utilizing viable and nonviable organisms in both experimental and natural environmental conditions9 13. Preliminary studies have indicated several cross antigens between our Neisseria vaccine and M. bovis. This apparent cross antigenicity appears to be the basis for the induced protective immunity to M. bovis. A vaccine utilizing the concept of cross-antigenicity is currently used in inducing resistance against canine distemper with a modified live measles virus. a.Why M. bovis does not produce a similar immunity to itself is unclear. This may be the key to both the pathogenicity of M. bovis in bovine cornea and the difficulty of previous investigators in using M. bovis as an effective vaccine against itself.

Early Dark Energy at High Redshifts: Status and Perspectives

description: Early dark energy models, for which the contribution to the dark energy density at high redshifts is not negligible, influence the growth of cosmic structures and could leave observable signatures that are different from the standard cosmological constant cold dark matter ($Λ$CDM) model. In this paper, we present updated constraints on early dark energy using geometrical and dynamical probes. From WMAP five-year data, baryon acoustic oscillations and type Ia supernovae luminosity distances, we obtain an upper limit of the dark energy density at the last scattering surface (lss), $Ω_{\rm EDE}(z_{\rm lss})<2.3\times10^{-2}$ (95% C.L.). When we include higher redshift observational probes, such as measurements of the linear growth factors, Gamma-Ray Bursts (GRBs) and Lyman-$α$ forest (\lya), this limit improves significantly and becomes $Ω_{\rm EDE}(z_{\rm lss})<1.4\times10^{-3}$ (95% C.L.). Furthermore, we find that future measurements, based on the Alcock-Paczyński test using the 21cm neutral hydrogen line, on GRBs and on the \lya forest, could constrain the behavior of the dark energy component and distinguish at a high confidence level between early dark energy models and pure $Λ$CDM. In this case, the constraints on the amount of early dark energy at the last scattering surface improve by a factor ten, when compared to present constraints. We also discuss the impact on the parameter $γ$, the growth rate index, which describes the growth of structures in standard and in modified gravity models.

\If I speak false\" : reading the oppositional in Peter Carey's True history of the Kelly Gang"
Creators: name: Mead, E
Publisher: name: University Of Tasmania
Year: 2023

description: My thesis offers a detailed textual analysis of Peter Carey's Booker Prize-winning novel True History of the Kelly Gang. Adopting a postcolonial approach, the thesis uses Carey's representation of an iconic Australian hero as a conduit to questions of racial identity in the so-called reconciling nation. Its arguments stem from two major theoretical underpinnings: Alan Lawson's Second World theory, which designates settler nations such as Australia as \suspended between 'mother' and 'other' simultaneously colonized and colonizing\" and Ross Chambers' theory of narrative oppositionality in his book Room For Maneuver: Reading (the) Oppositional (in) Narrative. The thesis argues that Carey's text works hard to affect a change to the white Australian reader's economy of desire and to open up a space for an alternative mode of national belonging ‚ÄövÑvÆ one that replaces the \"sorry\" nation's discourse of atonement with what Ken Gelder and Jane M. Jacobs call a \"mutual (dis)possession\" of its cultural and geographical spaces. The thesis is organised according to what I see as the text's most compelling and potentially subversive oppositional strategies. Chapter One establishes a reading practice that resists the tendency among many Carey critics to too casually engage the terms \"postcolonial\" and \"postmodern.\" Chapter Two uses the trope of the motherland to explore the relationship between racial and sexual identity in Australian settler discourse: as a fiercely contested site of gendered and racial legitimacy the motherland provides a means to imagine a more subversive sexual landscape in which neither mother nor land is virginal. Chapter Three uses True History's intertextual relationship with Shakespeare's Henry Vas a starting point for examining the relationship between theatre and history. It argues that Carey's confusing deployment of theatre as a textual discourse and a narrative practice - and the entanglement of both with questions of historical agency ‚ÄövÑvÆ compels the reader to consider the ideological function of theatre and spectatorship in True History of the Kelly Gang as well as in other kinds of colonial and postcolonial histories. Chapter Four deploys critical discourses of postcolonial melancholia to analyse the text's engagement with convict memory and settler guilt. In this final chapter I consider the uneasy cohabitation between psychoanalysis and postcolonialism as a provocative metaphor for the text's oppositional failures and successes."

description: A field trial was conducted on a large dairy farm to evaluate the serum and colostral antibody responses to four commercially available enterotoxigenic E. coli (ETEC) diarrhea vaccines. Multiparous cows (n= 192) and 114 first calf heifers were randomly assigned to six treatment groups (Table 1). Groups A-D were vaccinated twice subcutaneously; the first dose 50-90 days prior to the expected calving date (at drying off); the second dose three weeks prior to calving. Group E was vaccinated only once at three weeks prior to calving and Group F served as the non-vaccinated controls. It was found that all of the commercially available vaccines tested in this field trial increased colostral and serum antibodies against ETEC. Calf performance or challenge studies were not done because of the sheer numbers of animals and that was beyond the scope of this trial. It also appears that a single vaccination using Coli-bovis at 2-3 weeks pre-partum will produce protective antibody levels in colostrum.

description: Suppose a large and dense point cloud of an object with complex geometry is available that can be approximated by a smooth univariate function. In general, for such point clouds the “best” approximation using the method of least squares is usually hard or sometimes even impossible to compute. In most cases, however, a “near-best” approximation is just as good as the “best”, but usually much easier and faster to calculate. Therefore, a fast approach for the approximation of point clouds using Chebyshev polynomials is described, which is based on an interpolation in the Chebyshev points of the second kind. This allows to calculate the unknown coefficients of the polynomial by means of the Fast Fourier transform (FFT), which can be extremely efficient, especially for high-order polynomials. Thus, the focus of the presented approach is not on sparse point clouds or point clouds which can be approximated by functions with few parameters, but rather on large dense point clouds for whose approximation perhaps even millions of unknown coefficients have to be determined.

Scintillation in Circinus
Creators: name: McCallum, Jamie Nigel
Publisher: name: University Of Tasmania
Year: 2023

description: This work is an investigation of the Circinus H20 megamasers, especially the unusual rapid variability seen in their flux density. It has been previously hypothesized that this was due to interstellar scintillation and one of the aims of this study was to test this. If scintillation proved to be the cause, then there was the potential application of Earth-Orbit synthesis to study the pas structure of the masers themselves. This was carried out by a monitoring campaign using the Tidbinbilla 70m telescope, joint VLBI imaging / time-delay detection experiments with the LBA (Long Baseline Array) and fullpolarization observations using the ATCA (Australia Telescope Compact Array). The results have shown good but not definitive evidence for the scintillation hypothesis, and specifically for quenched diffractive scintillation. The strongest single piece of evidence is in the detection of an apparent annual cycle at the 3˜ìvâ significance level. The fitted annual cycle is consistent with the non-detections of a time delay between the Tidbinbilla and ATCA telescopes in the simultaneous observations made in 2004. The quenched diffractive scintillation model successfully accounts for the observed properties of the variability by proposing a certain range of size and morphologies within the population of the Circinus megamasers. While consistent with the observations, the models have proved difficult to usefully test due to the extremely high levels of intrinsic variability that the monitoring campaign has revealed. It is hoped that future work will enable a more rigorous testing of the proposed models.
Effects of viscous dissipation on combined free and forced convection through vertical ducts and passages
Creators: name: Rokerya, M. Shafi
Publisher: name: University of British Columbia
Year: 2011

description: The effects of viscous dissipation on the flow phenomena and heat transfer rate for fully developed laminar flow through vertical ducts and passages has been analysed under the condition of combined free and forced convection. The fluid properties are considered to be constant except for the variation of density in the buoyancy term of the momentum equation. The thermal boundary condition of uniform heat flux per unit length in the flow direction has been considered. The investigation is carried out for two geometries; (a) Circular ducts and (b) Concentric annuli. The governing momentum and non-linear energy equations are solved for the circular duct by three methods; (i) Power Series Method (ii) Galerkin's Method and (iii) Numerical Integration Method. The solutions for the concentric annuli are obtained by Numerical Integration Method. Results for the velocity and temperature distribution in the flow field are obtained, and information of engineering interest like Nusselt numbers have been evaluated. For combined free and forced convection, the momentum and energy equations are coupled, and hence viscous dissipation affects both the velocity and temperature fields. The effect of viscous dissipation on the velocity field is to reduce the flow velocity near the heated wall(s) and thus it counteracts the effect of free convection on the velocity field for the present study of heating in upflow. The effect of viscous dissipation on the temperature field is to act as a heat source in the fluid and reduce the temperature differences in the system. Viscous dissipation opposes the externally impressed heating and reduces the heat transfer rate when the surface transfers heat to the fluid. Consequently, lower Nusselt number values are obtained when viscous dissipation is taken into consideration. The quantitative effect of viscous dissipation on Nusselt number is found to be small for the case of circular ducts. However, for flow through annular passages and for the corresponding values of the same parameters, the effect of viscous dissipation on the heat transfer rate may not be ignored.

Starting with the unpolarized electron and positron beam, the polarization transfer to the $Z_{cs}$ state and its decay angular distribution patterns are investigated. Some observables are suggested for determination of the spin parity quantum numbers. An ensemble of Monte-Carlo events are used to show some moment distributions special for manifestation of the different $Z_{cs}$ spin scenarios.

description: Inflammatory processes within the scrotum of the bull are common clinical occurrences. This project was designed to determine: ( I) if there was a decline in semen quality following unilateral orchiectomy; (2) the length of time required for semen quality to return to normal following surgery; (3) the magnitude and duration of alterations of normal scrotal thermographic patterns following surgery; and ( 4) comparison of the degree of surgical insult between bulls operated in winter and summer. Bulls subjected to this procedure for correction of pathological conditions can be expected to sustain minimal additional inflammation to the remaining testicle. It is proposed that the use of proper surgical technique, asepsis, brevity of surgical time and convalescence in clean quarters are important factors to minimize the insult to the remaining testicle.

description: We construct the networks of collaboration between partners for projects carried out with the support of European Commission Framework Programs FP5 and FP6. We analyze in detail these networks, not only in terms of total number of projects, but also for the different tools employed, the different geographical partitions, and the different thematic areas. For all cases we find a scale free behavior, as expected for such social networks, and also reported in the literature. In comparing FP5 to FP6, we show that despite a decrease in the number of signed contracts, and the total number of unique partners, there is an increase in the average number of collaborative partners per institution. Furthermore, we establish a measure for the central role (hub) for each country, by using the Minimum Spanning Tree (MST), which we construct in detail for each thematic area (e.g. Informatics, Nanoscience, Life Sciences, etc.). The importance of these network hubs is highlighted, as this information can be used by policy planners in designing future research plans regarding the distribution of available funds.

description: We have studied the low lying magnetic spectra of 12C, 16O, 40Ca, 48Ca and 208Pb nuclei within the Random Phase Approximation (RPA) theory, finding that the description of low-lying magnetic states of doubly-closed-shell nuclei imposes severe constraints on the spin and tensor terms of the nucleon-nucleon effective interaction. We have first made an investigation by using four phenomenological effective interactions and we have obtained good agreement with the experimental magnetic spectra, and, to a lesser extent, with the electron scattering responses. Then we have made self-consistent RPA calculations to test the validity of the finite-range D1 Gogny interaction. For all the nuclei under study we have found that this interaction inverts the energies of all the magnetic states forming isospin doublets.

description: We studied the rotational spectrum of oxirane in a sample of natural isotopic composition in selected regions between 158 GHz and 1093 GHz. Investigations of the isotopologs with one $^{13}$C or one $^{18}$O were the primary focus in order to facilitate searches for them in space. We also examined the main isotopic species mainly to look into the performance of Watson's A and S reductions both in an oblate and in a prolate representation. Even though oxirane is a rather asymmetric oblate rotor, the A reduction in the III$^l$ representation did not yield a satisfactory fit, as was observed frequently earlier for other molecules. The other three combinations yielded satisfactory fits of similar quality among each other; the A reduction in the I$^r$ representation required two parameters less than both S reduction fits.

Fescue Toxic Syndrome Update

Year: 1983

description: "Summer syndrome," "summer slump," "fescue toxicity" and "fescue toxicosis" are terms which have been widely used to denote poor animal performance by cattle grazing tall fescue during summer. Characteristic of this condition is reduced feed intake, decreased rate of gain and /or milk production, rough hair coat, rapid breathing, increased body temperature and a generally unthrifty condition. In recent years, this condition has been shown to be associated with an endophytic fungus. Research from several states has demonstrated that the endophyte is associated with quality problems in tall fescue. Interdisciplinary teams of researchers at different locations are presently engaged in studies attempting to provide answers to many remaining questions concerning the endophyte and tall fescue. Advances have been made in breeding and selection of fungus-free plants.

description: Introduction: Frailty is associated with adverse outcomes among patients attending emergency departments (EDs). While multiple frailty screens are available, little is known about which variables are important to incorporate and how best to facilitate accurate, yet prompt ED screening. To understand the core requirements of frailty screening in ED, we conducted an international, modified, electronic two-round Delphi consensus study. Methods: A two-round electronic Delphi involving 37 participants from 10 countries was undertaken. Statements were generated from a prior systematic review examining frailty screening instruments in ED (logistic, psychometric and clinimetric properties). Reflexive thematic analysis generated a list of 56 statements for Round 1 (August–September 2021). Four main themes identified were: (i) principles of frailty screening, (ii) practicalities and logistics, (iii) frailty domains and (iv) frailty risk factors. Results: In Round 1, 13/56 statements (23%) were accepted. Following feedback, 22 new statements were created and 35 were re-circulated in Round 2 (October 2021). Of these, 19 (54%) were finally accepted. It was agreed that ideal frailty screens should be short (<5 min), multidimensional and well-calibrated across the spectrum of frailty, reflecting baseline status 2–4 weeks before presentation. Screening should ideally be routine, prompt (<4 h after arrival) and completed at first contact in ED. Functional ability, mobility, cognition, medication use and social factors were identified as the most important variables to include. Conclusions: Although a clear consensus was reached on important requirements of frailty screening in ED, and variables to include in an ideal screen, more research is required to operationalise screening in clinical practice.
title: The Development and Evaluation of a Nutrient Density Based Nutrition Education Program for Elementary Schools
Creators: name: Brown, Guendoline
Publisher: name: Utah State University
Year: 1977

description: A behavioral objective based nutrition education program for kindergarten through sixth grade which allowed nutrition education to be integrated into existing classroom programs was developed and evaluated. A nutrient density approach served as the conceptual framework for the program. Nutrient density evaluates the nutrient content of a food in relationship to the caloric content. Materials for student use, teacher use and teacher training were developed.
The program was evaluated in 27 classrooms in nine public elementary schools in Utah and Idaho with 806 student participants. Pre-and post tests as well as classroom evaluations were conducted. Students, teachers and parents indicated that positive cognitive, attitudinal and behavioral effects resulted from the program.
Direct mapping of the finite temperature phase diagram of strongly correlated quantum models

description: Optical lattice experiments, with the unique potential of tuning interactions and density, have emerged as emulators of nontrivial theoretical models that are directly relevant for strongly correlated materials. However, so far the finite temperature phase diagram has not been mapped out for any strongly correlated quantum model. We propose a remarkable method for obtaining such a phase diagram for the first time directly from experiments using only the density profile in the trap as the input. We illustrate the procedure explicitly for the Bose Hubbard model, a textbook example of a quantum phase transition from a superfluid to a Mott insulator. Using "exact" quantum Monte Carlo simulations in a trap with up to $10^6$ bosons, we show that kinks in the local compressibility, arising from critical fluctuations, demarcate the boundaries between superfluid and normal phases in the trap. The temperature of the bosons in the optical lattice is determined from the density profile at the edge. Our method can be applied to other phase transitions even when reliable numerical results are not available.

Bose-Einstein condensation and the magnetically ordered state of TlCuCl3

description: The dimerized S=1/2 spins of the Cu ions in TlCuCl3 are ordered antiferromagnetically in the presence of a field larger than about 54 kOe in the zero-temperature limit. Within the mean-field approximation all thermal effects are frozen out below 6 K. Nevertheless, experiments show significant changes of the critical field and the magnetization below this temperature, which reflect the presence of low-energetic dimer-spin excitations. We calculate the dimer-spin correlation functions within a self-consistent random-phase approximation, using as input the effective exchange coupling parameters obtained from the measured excitation spectra. The calculated critical field and magnetization curves exhibit the main features of those measured experimentally, but differ in important respects from the predictions of simplified boson models.

The merging galaxy cluster Abell 3266 at low radio frequencies

description: We present new low-frequency ($ν= 88$-216 MHz) observations of the complex merging galaxy cluster Abell 3266. These new observations are taken with the Murchison Widefield Array (MWA) in its Phase II 'extended', long-baseline configuration, offering the highest-resolution low-frequency view of the cluster to date. We report on the detection of four steep spectrum ($α\lesssim -1$ for $S_ν\propto ν^α$) extended radio sources within the cluster. We confirm the detection of a $\sim 570$ kpc radio relic to the south of the cluster, and a possible bridge of emission connecting the relic to the cluster core. We also detect two new ultra-steep-spectrum ($α\lesssim -1.7$) fossil plasma sources to the north and west of the cluster centre without associated compact radio emission. A previously detected radio galaxy in the cluster is also found to have a spectrally steepening tail with steep-spectrum components highlighted by the MWA. We do not detect a giant radio halo in the cluster. After simulating a range of radio haloes at 216 MHz we place upper limits on the radio luminosity corresponding to $\sim 7.2 \times 10^{24}$ W Hz$^{-1}$ at 150 MHz assuming the expected 500 kpc radius, up to a factor 5 lower than expected from scaling relations. Why a giant radio halo is undetected in Abell 3266 is unclear - the timeline of the merger and overall mass of the system as determined by optical and X-ray studies suggest the foundation for a hosting system.

title: The Relationship of Molybdenum to Iron Status in Pregnancy and Anemia in Rats and Humans
Creators: name: Mortensen, Jo Ann
Publisher: name: Utah State University
Year: 1977

description: Weanling male rats were made anemic and fed diets supplemented with 20 ppm iron and/or 2 ppm molybdenum. A decrease in serum iron was observed in the rats supplemented only with iron and a significant decrease in hemoglobin was observed in rats given no supplementation.
In a second experiment, pregnant female rats were also fed diets supplemented with 20 ppm iron and/or 2 ppm molybdenum. An inverse relationship was apparent between iron and copper in both the serum and the liver of the female rats. The livers of their pups displayed an inverse relationship between molybdenum and copper. Hemoglobin in both dams and pups tended to decrease when: (1) supplemental molybdenum was absent but supplemental iron was present; (2) supplemental iron was absent but supplemental molybdenum was present; and (3) no supplementation was given at all. While there appeared to be little placental transfer of molybdenum, iron and copper seemed to be transferred from the dams' liver.
In a third experiment, serum was collected from pregnant women in first, second, and third trimester, and at postpartum. Both serum iron and serum molybdenum decreased significantly at postpartum. Inverse relationships were apparent between (1) serum iron and serum copper, and (2) serum molybdenum and serum copper.
