description: The Crab nebula and pulsar have been widely used as a calibration source for X-ray instruments. The in-flight effective area calibration of the Reflection Grating Spectrometers (RGS) of XMM-Newton depend upon the availability of reliable calibration sources. We investigate how the absolute effective area calibration of RGS can be obtained using Crab as a standard candle. We have analysed RGS observations of the Crab using different instrument configurations and spatial offsets, and made use of previous determinations of the continuum spectrum of the nebula plus pulsar. Due to the high spectral resolution of the RGS, we resolve the main absorption edges and detect the strong 1s-2p absorption lines of neutral oxygen. We get an excellent fit to the Crab spectrum using this fixed continuum and the absorption spectrum determined by RGS. We get accurate column densities for the neutral atoms of H, N, O, Ne, Mg, and Fe, as well as a clear detection of Fe II and firm upper limits for other ions. Our data are in good agreement with earlier optical and UV spectroscopic measurements of some of these ions. We find solar abundances for N and O, while Ne is overabundant by a factor of 1.7 and Fe is underabundant by a factor of 0.8. We confirm that there is less dust in the line of sight compared to the prediction based on the absorption column. Our spectra suggest a more prominent role of ferric iron in the dust compared to ferrous iron. Our high-resolution observations confirm that Crab can be used as an X-ray calibration source. RGS spectra have determined the absorption spectrum towards Crab with unprecedented detail.

A five-wave HLL Riemann solver for relativistic MHD

description: We present a five-wave Riemann solver for the equations of ideal relativistic magnetohydrodynamics. Our solver can be regarded as a relativistic extension of the five-wave HLLD Riemann solver initially developed by Miyoshi and Kusano for the equations of ideal MHD. The solution to the Riemann problem is approximated by a five wave pattern, comprised of two outermost fast shocks, two rotational discontinuities and a contact surface in the middle. The proposed scheme is considerably more elaborate than in the classical case since the normal velocity is no longer constant across the rotational modes. Still, proper closure to the Rankine-Hugoniot jump conditions can be attained by solving a nonlinear scalar equation in the total pressure variable which, for the chosen configuration, has to be constant over the whole Riemann fan. The accuracy of the new Riemann solver is validated against one dimensional tests and multidimensional applications. It is shown that our new solver considerably improves over the popular HLL solver or the recently proposed HLLC schemes.

title: Utilization of Forage Plants and Diet of Sheep on Utah Winter Range
Creators: name: Green, Lisle R.
Publisher: name: Utah State University

description: Although there is an abundance of material available concerning forage consumption by livestock on pasture land and in the feed lot, there is relatively little known about the grazing habits and forage preferences of livestock under range conditions. There has been still less scientific effort expended toward solving the riddle of the grazing animal's diet under winter range conditions. Investigators have suggested means to determine the quantity of forage available on range areas, the carrying capacities of range lands, and methods of determining the degree to which forage has been utilized. The diet of the foraging animal is affected by the quantity of forage available, and the capacity of range lands to support grazing and the degree to which various species are utilized are directly dependent upon the diet, yet virtually nothing is known about the actual compositions of this diet as selected by the animal on the range. There is need for additional scientific information concerning choice of species by the foraging animal and the factors which affect this selection. Basic information of this nature must be known before scientific range management can be applied. Sheep are known to prefer certain plants, and likewise certain portions of these plants. In addition weather, stage of maturity, intensity of use, and plant associations all affect the sheep's diet, and make interpretations and calculations still more complex. This study was designed to determine on the winter range the quantity of forage available to grazing animals, these species composition of the animal's diet, and to evaluate, where possible, factors affecting the diet.

description: A nearest-neighbor-interaction Ising spin glass, in the presence of an external magnetic field, is studied on different hierarchical lattices that approach the cubic lattice. The magnetic field is considered as uniform, or random (following either a bimodal or a Gaussian probability distribution). In all cases, a spin-glass attractor is found, in the plane magnetic field versus temperature, associated with a low-temperature phase. The physical consequences of this attractor are discussed, in view of the present scenario of the spin-glass problem.

Creators: name: Heaton, Lucy V.
Publisher: name: Utah State University

description: One of the most remarkable developments of the present age is the apparently large increase in the reading public. The vast output of reading materials being purchased would seem to be evidence that reading is playing an increasingly important part in the daily lives of most people. Magazines and other publications crowd our stores, our homes, our very tables; at first glance, one would think that reading matter usurps our attention, and that we have come to depend upon it. The modern reader glances at the label on a can to learn its contents and uses. He reads the weather forecast and dresses accordingly; he looks to the want-ads for a second-hand typewriter, an apartment, or a lost purse. If the world were suddenly deprived of all printed material, it is probably that many people in the United States would find life exceedingly empty. That the educational world is coming to realized the fundamental importance of reading in the life of the individual citizen is shown by the increasing amount of attention which is being given the subject by scientific investigators. Interest in and a desire for knowledge concerning the reading habits of adults and the factors which affect these habits have developed rapidly during the past few years. Some of the most significant contributions which have been made recently in the field of educational research have been studies of phases of the reading process. The studies reveal that the dominant reading interests of the American people have varied with their changing needs and ideals. Furthermore, these same reading interests have exerted a strong influence upon the nature of the materials supplied for school reading, for religious study, and for the influencing of the people's loyalty to the nation. There are several reasons for the new emphasis upon the reading habits of adults: first, the efforts of librarians and educators generally to promote adult education, and second, the increased interest in reading by adults because of their own realization of its social utility. Also the fact that useful learning is not prevented by advancing age has had a great deal to do with the place of serious reading in a modern society, for it implies that serious reading is helpful at any age.

description: A simplicial polytope is combinatorially rigid if its combinatorial structure is determined by its graded Betti numbers which are important invariant coming from combinatorial commutative algebra. We find a necessary condition to be combinatorially rigid for 3-dimensional reducible simplicial polytopes and provide some rigid reducible simplicial polytopes.

description: Im Rahmen der AG „Citizen Science an/mit Schulen“ ist eine übersichtliche Handreichung für die Planung und Durchführung von Citizen-Science-Projekten mit Schulen entstanden. Unter dem Titel "Citizen Science – Forschen mit Schulen. Grundlagen, Empfehlungen & praktische Tipps für gemeinsame Projekte" formulierten Forschende und Lehrpersonen gemeinsam eine kompakte Hilfestellung für eine erfolgreiche Zusammenarbeit zwischen Wissenschaft und Schule in Citizen-Science-Projekten. Die Broschüre gliedert sich in sieben Kapitel: Einleitung Citizen Science in Österreich Mehrwert von Citizen Science an und mit Schulen Projektplanung und -durchführung Rechtliche und ethische Aspekte Rahmenbedingungen effektiv nutzen Kooperationen langfristig verankern Einen schnellen Überblick über die wichtigsten Punkte, die es bei Citizen-Science-Projekten an und mit Schulen zu beachten gilt, bietet eine handliche Checkliste am Ende der Broschüre. Im Rahmen der Erstellung kam es auch zu einer Zusammenarbeit mit Schülerinnen und Schülern. Alle Bilder entstammen einem Kreativwettbewerb, bei dem Kinder und Jugendliche Avatare, Icons und Kapitelillustrationen einreichen konnten. Die besten unter ihnen wurden von einer vierköpfigen Jury für die Publikation ausgewählt. Die AG „Citizen Science an/mit Schulen“ wird vom OeAD-Zentrum für Citizen Science (www.zentrumfuercitizenscience.at) geleitet und ist Teil des Citizen Science Network Austria.
title: A Curriculum Study of the Biological Science Courses in the Secondary Schools and College of Utah During 1947-48
Creators: name: Gunnell, Merrill H.
Publisher: name: Utah State University
Year: 1948

description: At the present time there is a feeling among biologists in Utah that there should be improvement in biological science courses and course sequence to better fill the needs of the non technical student. There are many students filling group requirements with an accumulation of courses which may not provide them with the more important fundamental concepts and principles in biology. Information concerning these courses in high schools and colleges in necessary to provide a basis for curriculum revision in the field. Such information should be useful in evaluating the present system and suggesting modifications. Because of the need for this information the present study was undertaken. However, it is not the object of this study to make recommendations about definite curriculum changes. The purpose, rather, is to determine the courses taught, the subject matter of such courses, student registration, and general student achievement in the various biological sciences as offered during the school year 1947-48, in the high schools of Utah, and in the lower division of the ten colleges in Utah.

description: We use microwave excitation to elucidate the dynamics of long superconductor / normal metal / superconductor Josephson junctions. By varying the excitation frequency in the range 10 MHz - 40 GHz, we observe that the critical and retrapping currents, deduced from the dc voltage vs. dc current characteristics of the junction, are set by two different time scales. The critical current increases when the ac frequency is larger than the inverse diffusion time in the normal metal, whereas the retrapping current is strongly modified when the excitation frequency is above the electron-phonon rate in the normal metal. Therefore the critical and retrapping currents are associated with elastic and inelastic scattering, respectively.

Evolutionary dynamics on rugged fitness landscapes: exact dynamics and information theoretical aspects

description: The parallel mutation-selection evolutionary dynamics, in which mutation and replication are independent events, is solved exactly in the case that the Malthusian fitnesses associated to the genomes are described by the Random Energy Model (REM) and by a ferromagnetic version of the REM. The solution method uses the mapping of the evolutionary dynamics into a quantum Ising chain in a transverse field and the Suzuki-Trotter formalism to calculate the transition probabilities between configurations at different times. We find that in the case of the REM landscape the dynamics can exhibit three distinct regimes: pure diffusion or stasis for short times, depending on the fitness of the initial configuration, and a spin-glass regime for large times. The dynamic transition between these dynamical regimes is marked by discontinuities in the mean-fitness as well as in the overlap with the initial reference sequence. The relaxation to equilibrium is described by an inverse time decay. In the ferromagnetic REM, we find in addition to these three regimes, a ferromagnetic regime where the overlap and the mean-fitness are frozen. In this case, the system relaxes to equilibrium in a finite time. The relevance of our results to information processing aspects of evolution is discussed.

description: Dehydroamino acids are a class of noncanonical unsaturated amino acids commonly found in various naturally occurring peptides and proteins. In this study, we successfully cloned and heterologously expressed the cda biosynthetic gene cluster from Streptomyces nitrosporeus ATCC 12769 in Streptomyces lividans TK24, leading to the identification of three α,β-dehydroamino acid derivatives, designated as catedehas A–C (1–3). Among these, compound 2, although previously reported, lacked any detailed characterisation data. Their structures were elucidated by high-resolution electrospray ionisation mass spectrometry, 1D and 2D nuclear magnetic resonance spectroscopy, along with other spectroscopic techniques. Compounds 1–3 exhibited remarkable antioxidant activity in DPPH· free radical scavenging assay, with IC50 values of 27.52, 12.51, and 8.32 μM, respectively.

title: Participation and Leadership in Voluntary Agencies at Plain City, Utah, 1947

description: Western culture emphasizes the ideal of individual attainment in social, pol1tical, religious, and economic fields. The development of qualities of leadership through participation in communal activities by all persons in a community has served as a battle cry for democracy. The acceptance of the free school system meant that everyone was to have a chance to achieve. But equality did not come with opportunity. Somehow the abler ones moved along at a faster rate. Certainly, with all the emphasis on achievement, groups differ widely in the extent to which leadership is dispersed, in the nature of attendance at group functions, and in the character of participation of those who attend. It has been said that the purpose of a community study is to affect a more constructive socialisation program for the future. It is assumed the material found herein may be useful in further understanding rural community life. This study is being made to ascertain the extent to which participation is dispersed and the amount, kinds, and location of social activities and leadership among the people of Plain City, Utah, in activities other than those directly concerned with gaining a livelihood. It is the specific intention of this inquiry: 1. To determine the extent to which the people of Plain City use their own local institutions and the institutions of other communities. 2. To learn the difference in the use of these institutions by farmer groups and non-farmer groups, by age groups, and by groups according to marital status. 3. To clarity the nature and type of leadership in the community. 4. To ascertain the nature of the participation of these people at group gatherings. An analysis of the data secured in this study may assist in showing the weaknesses or strengths of the present methods of attaining individual socialization. It is hoped that it may also throw some light on the success of the institutions involved in the process.

Quantum computation in correlation space and extremal entanglement

description: Recently, a framework was established to systematically construct novel universal resource states for measurement-based quantum computation using techniques involving finitely correlated states. With these methods, universal states were found which are in certain ways much less entangled than the original cluster state model, and it was hence believed that with this approach many of the extremal entanglement features of the cluster states could be relaxed. The new resources were constructed as "computationally universal" states--i.e. they allow one to efficiently reproduce the classical output of each quantum computation--whereas the cluster states are universal in a stronger sense since they are "universal state preparators". Here we show that the new resources are universal state preparators after all, and must therefore exhibit a whole class of extremal entanglement features, similar to the cluster states.

Creators: name: Bennett, William H.
Publisher: name: Utah State University
Year: 1948

description: Twenty-four alfalfa varieties, representing four varietal groups, were compared for nitrogen content and protein yield. A highly significant difference between varieties was noted for nitrogen content, and a significant difference for protein yield. Saskatchewan 666 had the highest content in the first cutting, but Ledak 22009 had the highest content in the third. Group differences were not significant. Crop differences were highly significant for nitrogen content, yield of forage, and of protein. In the case of every variety, the third cutting was richer in nitrogen than the second and the seemed was richer than the first. Protein yield, however, was affected more by forage weight than by nitrogen content, and most varieties gave more than 45 percent of their total annual production of protein in the first cutting. High forage yield was associated with a low percentage of nitrogen. The data obtained in this study are for one year only and pertain to crop material harvested the first year after planting.

description: Disk fragmentation resulting from the gravitational instability has been proposed as an efficient mechanism for forming giant planets. We use the planet Fomalhaut b, the triple-planetary system HR 8799, and the potential protoplanet associated with HL Tau to test the viability of this mechanism. We choose the above systems since they harbor planets with masses and orbital characteristics favored by the fragmentation mechanism. We do not claim that these planets must have formed as the result of fragmentation, rather the reverse: if planets can form from disk fragmentation, then these systems are consistent with what we should expect to see. We use the orbital characteristics of these recently discovered planets, along with a new technique to more accurately determine the disk cooling times, to place both lower and upper limits on the disk surface density--and thus mass--required to form these objects by disk fragmentation. Our cooling times are over an order of magnitude shorter than those of Rafikov (2005),which makes disk fragmentation more feasible for these objects. We find that the required mass interior to the planet's orbital radius is ~0.1 Msun for Fomalhaut b, the protoplanet orbiting HL Tau, and the outermost planet of HR 8799. The two inner planets of HR 8799 probably could not have formed in situ by disk fragmentation.
