title: Stability of Stream Communities Exposed to Underground Nuclear Tests on Amchitka, Aleutian Islands, Alaska
Creators: name: Valdez, Richard Ames
Publisher: name: Utah State University
Year: 1975

description: A major bioenvironmental effect of The United States Atomic Energy Commission's Underground Nuclear Testing Program on Amchitka Island, Alaska was the decimation of stream communities by drilling muds from the device emplacement holes. These muds reached two of these streams 4 months and 2 years before the Milrow and Cannikin tests, respectively. Recolonization of fishes and macroinvertebrates in these small streams (Clevenger and White Alice Creeks) began 1 month after spill abatement.
Complete recovery of Dolly Varden in Clevenger Creek occurred less than 5 years after the spill. Of the other native fishes, pink salmon spawned 1 1/2 years after the spill and threespine stickleback, which were formerly rare in the stream, remained absent after 5 years. Although the midge Chironomus riparius recovered completely in 2 1/2 years, populations of three of the nine sympatric macroinvertebrates were still below the pre-spill densities after 5 years. Annual production of juvenile Dolly Varden in Clevenger Creek 3 and 4 years after the spill (42.45 and 43.58 kg ha-1, dry weight) surpassed the pre-spill estimate (40.21 kg ha-1) because of the predominance of new year classes in the recovering population, and not because of increased growth rates. Annual production of the recovering midges in Clevenger Creek 3 years after the spill was about 1 1/2 times the pre-spill estimate (8.12 and 12.01 gm m-2, dry weight), because of high densities from reduced competition by sympatric macroinvertebrates and predation by Dolly Varden. Rapid expulsion of the pollutant by high runoffs and immigration of individuals from unaffected areas of the stream sped the initial recolonization. The increased turbidity and some bank sloughing caused by the Milrow event did not hinder this recovery.
The spill that decimated the communities of White Alice Creek, persisted for 1 1/2 years and slowed the recovery of fishes and macroinvertebrates in that stream. Physical damage and alteration of stream habitat by the Cannikin device further inhibited recolonization.
Macroinvertebrate species diversity of unperturbed Amchitka streams was low when compared to that of continental streams. The response of this index to seasonal variations in density invalidated its use as a sensitivity index to perturbations in these simply-structured island communities. The stability of these low diversity communities was not thoroughly evaluated, since their resistence was not thoroughly tested; the mud spills seemed toxic enough to have decimated most stream populations. However, resilience, or the recooperative process, appeared high as indicated by rapid recolonization of native species after abatement.
Magnetic transitions induced by tunnelling electrons in individual adsorbed M-Phthalocyanine molecules (M $\equiv$ Fe, Co)

description: We report on a theoretical study of magnetic transitions induced by tunnelling electrons in individual adsorbed M-Phthalocyanine (M-Pc) molecules where M is a metal atom: Fe-Pc on a Cu(110)(2$\times$1)-O surface and Co-Pc layers on Pb(111) islands. The magnetic transitions correspond to the change of orientation of the spin angular momentum of the metal ion with respect to the surroundings and possibly an applied magnetic field. The adsorbed Fe-Pc system is studied with a Density Functional Theory (DFT) transport approach showing that i) the magnetic structure of the Fe atom in the adsorbed Fe-Pc is quite different from that of the free Fe atom or of other adsorbed Fe systems and ii) that injection of electrons (holes) into the Fe atom in the adsorbed Fe-Pc molecule dominantly involves the Fe $3d_{z^2}$ orbital. These results fully specify the magnetic structure of the system and the process responsible for magnetic transitions. The dynamics of the magnetic transitions induced by tunnelling electrons is treated in a strong-coupling approach. The Fe-Pc treatment is extended to the Co-Pc case. The present calculations accurately reproduce the strength of the magnetic transitions as observed by magnetic IETS (Inelastic Electron Tunnelling Spectroscopy) experiments; in particular, the dominance of the inelastic current in the conduction of the adsorbed M-Pc molecule is accounted for.

description: We present a quenched lattice calculation of all six form factors: vector [f_1(q^2)], weak magnetism [f_2(q^2)], induced scalar [f_3(q^2)], axial-vector [g_1(q^2)], weak electricity [g_2(q^2)] and induce pseudoscalar [g_3(q^2)] form factors in hyperon semileptonic decay Xi^0 -> Sigma^{+} l nu using domain wall fermions. The q^2 dependences of all form factors in the relatively low q^2 region are examined in order to evaluate their values at zero momentum transfer. The Xi^0 -> Sigma^+ transition is highly sensitive to flavor SU(3) breaking since this decay corresponds to the direct analogue of neutron beta decay under the exchange of the down quark with the strange quark. The pattern of flavor SU(3) breaking effects in the hyperon beta decay is easily exposed in a comparison to results for neutron beta decay. We measure SU(3)-breaking corrections to f_1(0), f_2(0)/f_1(0) and g_1(0)/f_1(0). A sign of the leading order corrections, of which the size is less than a few %, on f_1(0) is likely negative, while f_2(0)/f_1(0) and g_1(0)/f_1(0) receive positive corrections of order 16% and 5% respectively. The observed patterns of the deviation from the values in the exact SU(3) limit does not support some of model estimates. We show that there are nonzero second-class form factors in the Xi^0 -> Sigma^+ decay, measuring f_3(0)/f_1(0)=0.14(10) and g_2(0)/g_1(0)=0.68(18), which are comparable to the size of first-order SU(3) breaking. It is also found that the SU(3) breaking effect on g_3(0)/g_1(0) agree with the prediction of the generalized pion-pole dominance.

description: We propose and analyze a setup to achieve strong coupling between a single trapped atom and a mechanical oscillator. The interaction between the motion of the atom and the mechanical oscillator is mediated by a quantized light field in a laser driven high-finesse cavity. In particular, we show that high fidelity transfer of quantum states between the atom and the mechanical oscillator is in reach for existing or near future experimental parameters. Our setup provides the basic toolbox for coherent manipulation, preparation and measurement of micro- and nanomechanical oscillators via the tools of atomic physics.

title: Alfalfa Seed Production in Millard County, Utah as Related to Soil Type
Creators: name: Whornham, George
Publisher: name: Utah State University
Year: 1932

description: Alfalfa has a wide range of adaptability as a forage plant, but the areas in which it will produce seed successfully are extremely limited. These sections are confined almost exclusively to the arid or semi-arid regions of the world. In all other areas it is primarily a question of seasonal fitness. The extreme localization may be further emphasized by the fact that within the highest producing counties there are appreciable areas of land not suitable for seed production.

description: The energy spectrum of cosmic rays in the range 10^15 eV to 6*10^19 eV has been studied using the air Cherenkov light detectors of the Yakutsk array. The total flux of photons produced by relativistic electrons (including positrons as well, hereafter) of extensive air showers in the atmosphere is used as the energy estimator of the primary particle initiating a shower. The resultant differential flux of cosmic rays exhibits, in accordance with previous measurements, a knee and ankle features at energies 3*10^15 and ~10^19 eV, respectively. A comparison of observational data with simulations is made in the knee and ankle regions in order to choose the models of galactic and extragalactic components of cosmic rays which describe better the energy spectrum measured.

title: Streaming Current and Streaming Potential Induced by Water Flow Through Porous Media
Creators: name: Abaza, Mohamed M. I.
Publisher: name: Utah State University
Year: 1966

description: This study was conducted to investigate analytically and experimentally the relationship between the rate of flow of water through porous material and the streaming current and streaming potential induced by this flow. The effect of dissolved salts in the permeating solution and the size of the soil particles was also investigated.
Results and conclusions of this study are summarized as follows:

A modified procedure using the appropriate delay to insure stead state conditions was used for the measurements of both streaming current and streaming potential.
The flow-pressure relationship was the same irrespective of the counter electro-osmosis (resulting from the streaming potential) and the change in salt concentration. Flows through the samples tested thus followed Darcy's Law.
The rate of flow (at a constant salt concentration and soil particle diameter) is directly proportional to the induced streaming current and streaming potential. Emperical equations in the form of I = C1q and E = C2q are suggested.
A decrease in both streaming current and streaming potential was observed with increase of salt concentrate in the permeating solution. Comparable results were obtained for simulated natural waters and NaCl and KCl solutions, provided that the conductance of the solution was taken as a parameter.
A decrease in current and potential was observed with increase of soil particle diameter.
a Relationships of the form α = bN and β = C log N + d are suggested to express the effects of particle size and salt concentration on the streaming current and the streaming potential induced by the flow.
Induced streaming potential was found to increase with the decrease in temperature.
The analytical relationships developed together with the experimental work could probably be used as the basis of a method for measuring the rate of flow through porous material.
title: Irrigation Water Management Potential in the Bear River Delta
Creators: name: Austin, Tom Al
Publisher: name: Utah State University
Year: 1970

description: The purposes of this study were to evaluate the present irrigation efficiencies of the Bear River delta area of northern Utah and to propose a set of management proposals to improve the irrigation efficiency. In order to evaluate the present use, all pertinent data on the water resources of the Bear River delta had to be assembled and analyzed.
A hydrologic budget is a method used to account for all inflows, outflows, and changes in storage within a given area. In this study, all inflows and changes in storage were evaluated and the outflow was predicted. In this manner the management proposals could be tested to determine their effect on the outflow. The time base used in the budget analysis was chosen as monthly over the period 1931 - 1960. The mean annual outflow from the delta area to the Great Salt Lake was estimated to be 891,000 acre feet as surface outflow and 27,500 acre feet as groundwater outflow.
Irrigation requirement can be defined as the volume of water, measured at the point of diversion, required to meet crop potential consumptive uses. Irrigation requirement is a function of the system efficiency and includes the water "lost" from the conveyance and storage facilities. When compared to the present mean cropland diversions, a deficit or surplus water supply exists. These parameters were evaluated for both the present and the future estimated irrigation system efficiencies.
The present irrigation efficiency was estimated from potential consumptive use data and seepage loss data from surrounding areas. The present system efficiency was estimated to be 44 percent but with the implementation of the outlined general set of management proposals, the system efficiency was estimated to be increased to 62 percent. These management proposals result in an adequate water supply for all crop needs under the present cropland diversions, assuming adequate additional storage could be provided to redistribute the water to coincide with the demands. Under the present irrigation efficiency, the crop requirements are only being partially met.
It was estimated from the estimated future system efficiency, irrigation requirements, and the mean cropland diversions that water is available for export. The mean annual quantity of water available for export was estimated to be 630,000 acre feet. Most of this water is available for export during the non-growth months which requires large storage facilities at the points of useage. Further investigation is needed to determine the effect of this exportation on the ecology of the Great Salt Lake and the surrounding marsh lands.

description: An approach to calculate microscopic optical potential (OP) with the real part obtained by a folding procedure and with the imaginary part inherent in the high-energy approximation (HEA) is applied to study the $^8$He+p elastic scattering data at energies of tens of MeV/nucleon (MeV/N). The neutron and proton density distributions obtained in different models for $^{8}$He are utilized in the calculations of the differential cross sections. The role of the spin-orbit potential is studied. Comparison of the calculations with the available experimental data on the elastic scattering differential cross sections at beam energies of 15.7, 26.25, 32, 66 and 73 MeV/N is performed. The problem of the ambiguities of the depths of each component of the optical potential is considered by means of the imposed physical criterion related to the known behavior of the volume integrals as functions of the incident energy. It is shown also that the role of the surface absorption is rather important, in particular for the lowest incident energies (e.g., 15.7 and 26.25 MeV/nucleon).

title: Simulation and Analysis of Stream-Aquifer Systems
Creators: name: Bittinger, Morton W.
Publisher: name: Utah State University
Year: 1967

description: As defined for this study, a stream-aquifer system is a hydrologic system in which there is an intimate hydraulic interrelationship between one or more aquifers and a perennial stream. The objectives of this study are to better understand the response behavior of typical stream-aquifer systems, to look at the response behavior as influenced by water management practices, and to consider the problems and possibilities of integrated management of groundwater and surface water supplies within stream-aquifer systems.
A brief history of water development practices and policy, particularly in the Western United States, indicates that the tendency over the years has been to attempt to improve efficiency of use and increase water availability by means of coordinated management of sources and uses of water within hydrologic units. This tendency is manifested by the concepts of "basin planning," "multiple purpose projects," and "comprehensive planning." Also, history shows that surface and groundwater have typically been developed separately with little regard for the interrelationships between the two.
Through the cooperation of the U.S. Geological Survey, major stream-aquifer systems in the Western United States have been identified. The Soil Conservation Service provided information on water management problems, causes, and needs found within the major stream-aquifer systems. Components of stream-aquifer systems are classified into (1) input variables, (2) system parameters, (3) output or system responses. Techniques for modeling stream-aquifer systems are discussed, and the mathematical model technique used is presented.
Over 160 stream-aquifer systems were simulated, utilizing mathematical models and digital computer solutions. The response behavior was measured in terms of the change of groundwater levels and the pattern of outflow to the stream. The latter system response is emphasized because of the effect upon other water users which is often not considered when changes are made in water management practices. The influence of such variables and parameters as (1) the total water added to the aquifer, (2) the time distribution of the water added, (3) the areal distribution of the water added, (4) the aquifer hydraulic characteristics, (5) the geometric characteristics of the aquifer, and (6) the initial configuration of the water table surtace are discussed with results presented in tabular and graphical form.
The effect of common water management practices (drainage, phreatophyte control, improvement of irrigation efficiency, and lining of canals), along with further water management practices desirable in a fully integrated streamaquifer system are discussed.
The structure of the acenaphthene-1,2-diol dinitrates and their reaction with pyridine
Creators: name: Csizmadia, Imre
Publisher: name: University of British Columbia
Year: 2012

description: Calculation of bond angles from the available X-ray diffraction data for acenaphthene, indicated that the five-membered ring is planar and that cis-1,2-substituents are fully eclipsed and transsi.2-rsubstituents fully staggered in this ring system. These conclusions were confirmed by the ease of formation of cyclic carbonate and isopropylidene derivatives of the cis-acenaphthene-1,2-diol and the failure of the trans-isomer to form these new derivatives. The presence of intramolecular hydrogen bonds in the crystalline cis-diol and the absence of such bonds in the trans-diol also supported this structure. A single carbonyl stretching frequency of 1718 cm⁻¹ was found in the spectrum of pure acenaphthenequinone and the reported second band around 1770 cm⁻¹ was shown to be due to an impurity. A linear relation of the C=O and C-O-C stretching frequencies of the cis- and trans- diacetate and dibenzoate esters of the acenaphthene-1,2-diols was determined and compared with a similar relationship found for steroid esters. The dinitrate esters of the cis- and trans-acenaphthene-1,2-diols were prepared and characterized and the rates of their reactions with anhydrous pyridine were compared with!:those of other cyclic diol dinitrates. The dinitrates decomposed in a first order reaction with half lives of 90 and 610 minutes for the trans- and cis- isomers respectively at 25°C. A combination of chromatographic and spectrophotometry techniques was developed for rapid and accurate analyses of mixtures containing nitrate esters. An ultramicro-Kjeldahl procedure was developed for the determination of covalent nitrate nitrogen on a microgram scale.

description: A composite conductive material, which consists of fibers of a high conductivity in a matrix of low conductivity, is discussed. The effective conductivity of the system considered is calculated in Clausius-Mossotti approximation. Obtained relationships can be used to calculate the conductivity of a matrix, using experimentally measured parameters. Electric fields in the matrix and the inclusions are calculated. It is shown that the field in a low-conductivity matrix can be much higher than the external applied one.

title: Essential Amino Acid Composition of a Balanced Chick Diet
Creators: name: Dobson, Donald Christensen
Publisher: name: Utah State University
Year: 1961

description: The scientific balancing of diets has resulted in a series of studies to determine a standard for amino acid adequacy of a chick ration. These studies have shown that some amino acids are required in a chick diet more than others; they are termed "essential amino acids". Proteins used in formulating rations vary widely in essential amino acid content. Because of this variation, it can no longer be said that a diet with so much protein (N x 6.25) is adequate to meet the chick's need for optimum performance. Many papers have been published showing the results of experiments for determining the minimum levels of amino acids required in a chick's ration.

description: The energy gradient method is used to analyze the turbulent generation in the transition boundary layer flow. It is found that the maximum of the energy gradient function occurs at the wall for the Blasius boundary layer flow. At this location under a sufficiently high Reynolds number, even a low level of free-stream disturbance can cause the turbulent transition and sustain the flow to be in a state of turbulence. This is an excellent explanation of the physics of self-sustenance of wall turbulence. The mechanism of receptivity for boundary layer flow can also be understood from the energy gradient criterion. That is, the free-stream disturbance can propagate towards the wall by the "energy gradient" process to cause turbulent transition, and the transition point in boundary layer can be moved forward towards the leading edge when the level of external disturbance increases.

description: We measure the temperature of ultra-cold Rb-87 gases transferred into an optical lattice and compare to non-interacting thermodynamics for a combined lattice--parabolic potential. Absolute temperature is determined at low temperature by fitting quasimomentum distributions obtained using bandmapping, i.e., turning off the lattice potential slowly compared with the bandgap. We show that distributions obtained at high temperature employing this technique are not quasimomentum distributions through numerical simulations. To overcome this limitation, we extract temperature using the in-trap size of the gas.

description: We demonstrate with a quantum-mechanical approach that carbon nanotubes are excellent spin-current waveguides and are able to carry information stored in a precessing magnetic moment for long distances with very little dispersion and with tunable degrees of attenuation. Pulsed magnetic excitations are predicted to travel with the nanotube Fermi velocity and are able to induce similar excitations in remote locations. Such an efficient way of transporting magnetic information suggests that nanotubes are promising candidates for memory devices with fast magnetization switchings.

description: We study the electronic and magnetic properties of the quaternary AuMnSn$_{1-x}$Sb$_{x}$ Heusler alloys using first principles calculations. We determine their magnetic phase diagram and we show that they present a phase transition from a ferromagnetic to an antiferromagnetic state with increasing Sb concentration. For large Sb concentrations the antiferromagnetic superexchange coupling dominates over the ferromagnetic RKKY-like exchange mechanism. This behavior is similar to the one demonstrated by the isovalent Ni$_{1-x}$Cu$_x$MnSb alloy studied recently by the authors [I. Galanakis et al, Phys. Rev. B. \textbf{77}, 214417 (2008)]. Thus the variation of the concentration of the \textit{sp}-electrons (Sn and Sb atoms) and the variation of the concentration of the non-magnetic \textit{3d} atoms (Cu) lead to a similar tuning of the the magnetic properties of the Heusler alloys. We show that the inclusion of correlation effects does not alter the phase diagram. Calculated results are in good agreement with the available experimental data.

title: A Hydro-Quality Model to Predict the Effects of Biological Transformations on the Chemical Quality of Return Flow
Creators: name: Narasimhan, V. A.
Publisher: name: Utah State University
Year: 1975

description: A computerized mathematical model has been developed to simulate the system hydrology and water-salinity (as indicated by seven major ions constituting the salt) of a river basin, in which irrigation is the major beneficial water user. The overall system simulation model consists of three submodels: (1) a general hydrologic submodel programmed on a hybrid computer; (2) a chemical submodel to predict the quality of percolated water through the soil profile; and (3) a biological transformation submodel in respect of microbial nitrogen transformations, which is utilized by the chemical submodel. Both the chemical and biological submodels are programmed on a digital computer and are combined with the general hydrologic submodel to form the system simulation model. The overall model operates on monthly time intervals with variable spatial resolution.
The hydrologic portion of the model simulates the various hydrologic processes which are linked together by the continuity-of-mass principle and predicts the monthly runoff from the area. The chemical quality component of the model considers the complex chemistry of soilwater-plant system, including cation exchange on the soil complex, the dissolution or precipitation of lime (CaCO3), and calcium and magnesium sulphates ion pairs in solution.
The biological transformations submodel uses the kinetic approach in simulating the microbial nitrogen transformations within the root zone of a soil profile. The transformation reactions included are: (1) hydrolysis of Urea-nitrogen; (2) immobilization of ammonium-nitrogen; (3) mineralization of organic-nitrogen; and (4) immobilization of nitrate-nitrogen. The chemical composition of return flow is a function of these chemical and biological processes within the soil profile, in addition to blending of undiverted flows, evapotranspiration, and mixing of subsurface return flow with groundwater. Uptake of nitrate by aquatic biomass in the surface runoff of return flow has also been considered. The seven ions considered in the study are calcium, magnesium, sodium, sulphate, chloride, bicarbonate, and nitrate. The total dissolved solids outflow is a summation of these individual ions.
In order to demonstrate its capabilities, the hydro-quality model is applied to a large irrigated area of the Snake River Plains, near Twin Falls, Idaho. The model successfully simulated measured outflows of water and the concentration of seven ions for a 24 month period. The correlation coefficients range from 0.79 to 0.96 for the quantity and quality components of outflow, except for the sulphate ion, the correlation coefficient of which is 0.66. The model is general in nature and with suitable adjustments it can be applied to other areas and also to various kinds of management situations, including land application of waste water and studies involving nitrate pollution of groundwaters.

description: In calculations to date [1,2] of multi-layer stacks of dipolar condensates, created in one-dimensional optical lattices, the condensates have been assumed to be two-dimensional. In a real experiment, however, the condensates do not extend to infinity in the oblate direction, but have to be confined by a trap potential, too. By three-dimensional numerical simulations of this realistic experimental situation we find a crucial dependence of the phonon instability boundary on the number of layers. Moreover, near the boundary of the phonon instability, a variety of structured ground-state wave functions emerges, which may indicate the onset of a roton instability [3,4].

description: We present a general expression for a lognormal filter given an arbitrary nonlinear galaxy bias. We derive this filter as the maximum a posteriori solution assuming a lognormal prior distribution for the matter field with a given mean field and modeling the observed galaxy distribution by a Poissonian process. We have performed a three-dimensional implementation of this filter with a very efficient Newton-Krylov inversion scheme. Furthermore, we have tested it with a dark matter N-body simulation assuming a unit galaxy bias relation and compared the results with previous density field estimators like the inverse weighting scheme and Wiener filtering. Our results show good agreement with the underlying dark matter field for overdensities even above delta~1000 which exceeds by one order of magnitude the regime in which the lognormal is expected to be valid. The reason is that for our filter the lognormal assumption enters as a prior distribution function, but the maximum a posteriori solution is also conditioned on the data. We find that the lognormal filter is superior to the previous filtering schemes in terms of higher correlation coefficients and smaller Euclidean distances to the underlying matter field. We also show how it is able to recover the positive tail of the matter density field distribution for a unit bias relation down to scales of about >~2 Mpc/h.
