Chalcogen Bonds In Complexes Of Soxy (X, Y = F, Cl) With Nitrogen Bases, Luis Miguel Azofra, Ibon Alkorta, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

SOF2, SOFCl, and SOCl2 were each paired with a series of N bases. The potential energy surface of the binary complexes were characterized by MP2 calculations with double and triple-ξ basis sets, extrapolated to complete sets. The most stable configurations contained a S···N chalcogen bond with interaction energies as high as 6.8 kcal/mol. These structures are stabilized by a Nlp→σ*(S−Z) electron transfer (Z = O, F, Cl), complemented by Coulombicattraction of N to theσ-hole opposite the Z atom. N···S−F and N···S−Cl chalcogen bonds are stronger than N···S = O interactions.Formation of each chalcogen bond elongates all of the internalcovalent bonds …

Tensile Testing To Quantitate The Anisotropy And Strain Hardening Of Mozzarella Cheese, Ramona Bast, Prateek Sharma, Hannah K.B. Easton, Tzvetelin T. Dessev, Mita Lad, Peter A. Munro

Nutrition, Dietetics, and Food Sciences Faculty Publications

We explored anisotropy of mozzarella cheese: its presence is debated in the literature. Tensile testing proved a good method because the location and mode of failure were clear. Mozzarella cheese cut direct from the block showed no significant anisotropy, though confocal microscopy showed good structure alignment at a microscale. Deliberately elongated mozzarella cheese showed strong anisotropy with tensile strength in the elongation or fibre direction ∼3.5× that perpendicular to the fibres. Temperature of elongation had a marked impact on anisotropy with maximum anisotropy after elongation at 70 °C. We suggest the disagreement on anisotropy in the literature is related to …

Rainich-Type Conditions For Perfect Fluid Spacetimes, Dionisios Krongos, Charles G. Torre

Research Vignettes

In this worksheet we describe and illustrate a relatively simple set of new Rainich-type conditions on an n-dimensional spacetime which are necessary and sufficient for it to define a perfect fluid solution of the Einstein field equations. Procedures are provided which implement these Rainich-type conditions and which reconstruct the perfect fluid from the metric. These results provide an example of the idea of geometrization of matter fields in general relativity, which is a purely geometrical characterization of matter fields via the Einstein field equations.

Reply To Simon And Reed: Independent And Converging Results Rule Out Historic Disturbance And Confirm Age Constraints For Barrier Canyon Rock Art, Joel L. Pederson, Harriet Cornachione, Steven R. Simms, Reza Sohbati, Tammy M. Rittenour, Andrew S. Murray, Gary Cox

Geosciences Faculty Publications

We welcome this further discussion of our results on the age of the Great Gallery rock art in the Canyonlands of Utah. The comment by Simon and Reed (1) focuses on just one of the three components of our study (2), which is presented in greater technical detail in ref. 3 and is surely our best-constrained and least-surprising result: the dating of a rock-fall that removed some of the art and thus provides a minimum age. Simon and Reed (1) point out that the Great Gallery panel is not pristine and relate the sordid human history of visitation and possible …

Electron Parallel Closures For Arbitrary Collisionality, Jeong-Young Ji, Eric D. Held

All Physics Faculty Publications

Electron parallel closures for heat flow, viscosity, and friction force are expressed as kernel-weighted integrals of thermodynamic drives, the temperature gradient, relative electron-ion flow velocity, and flow-velocity gradient. Simple, fitted kernel functions are obtained for arbitrary collisionality from the 6400 moment solution and the asymptotic behavior in the collisionless limit. The fitted kernels circumvent having to solve higher order moment equations in order to close the electron fluid equations. For this reason, the electron parallel closures provide a useful and general tool for theoretical and computational models of astrophysical and laboratory plasmas.

Cartan Subalgebras, Compact Roots And The Satake Diagram For Su(2, 2), Ian M. Anderson

Tutorials on... in 1 hour or less

In this worksheet we use the 15-dimensional real Lie algebra su(2, 2) to illustrate some important points regarding the general structure theory and classification of real semi-simple Lie algebras.

1. Recall that a real semi-simple Lie algebra g is called a compact Lie algebra if the Killing form is negative definite. The Lie algebra g is compact if and only if all the root vectors for any Cartan subalgebra are purely imaginary. However, if the root vectors are purely imaginary for some choice of Cartan subalgebra it is not necessarily true that the Lie algebra is compact.

2. A real …

Effects Of Barbell Deadlift Training On Submaximal Motor Unit Firing Rates For The Vastus Lateralis And Rectus Femoris, Matt S. Stock, Brennan J. Thompson

Kinesiology and Health Science Faculty Publications

Previous investigations that have studied motor unit firing rates following strength training have been limited to small muscles, isometric training, or interventions involving exercise machines. We examined the effects of ten weeks of supervised barbell deadlift training on motor unit firing rates for the vastus lateralis and rectus femoris during a 50% maximum voluntary contraction (MVC) assessment. Twentyfour previously untrained men (mean age 524 years) were randomly assigned to training (n515) or control (n59) groups. Before and following the intervention, the subjects performed isometric testing of the right knee extensors while bipolar surface electromyographic signals were detected from the two …

Linear Operators That Preserve Graphical Properties Of Matrices: Isolation Numbers, Leroy B. Beasley, Seok-Zun Song, Young Bae Jun

Mathematics and Statistics Faculty Publications

Let A be a Boolean {0, 1} matrix. The isolation number of A is the maximum number of ones in A such that no two are in any row or any column (that is they are independent), and no two are in a 2 × 2 submatrix of all ones. The isolation number of A is a lower bound on the Boolean rank of A. A linear operator on the set of m × n Boolean matrices is a mapping which is additive and maps the zero matrix, O, to itself. A mapping strongly preserves a set, S, if it …

On Demand Cell Sectoring Based Fractional Frequency Reuse In Wireless Networks, Shakil Ahmed, Mohammad Arif Hossain, Mostafa Zaman Chowdhury

Electrical and Computer Engineering Student Research

In this paper, a dynamic channel assigning along with dynamic cell sectoring model has been proposed that focuses on the Fractional Frequency Reuse (FFR) not only for interference mitigation but also for enhancement of overall system capacity in wireless networks. We partition the cells in a cluster into two part named centre user part (CUP) and edge user part (EUP). Instead of huge traffic, there may be unoccupied channels in the EUPs of the cells. These unoccupied channels of the EUPs can assist the excessive number of users if these channels are assigned with proper interference management. If the number …

Refined Climate Downscaling For The Intermountain West, Robert R. Gillies, Rong Li, Shih-Yu (Simon) Wang, Jiming Jin

Browse all Datasets

Large biases associated with climate projections are problematic when it comes to their regional application in the assessment of water resources and ecosystems. We produced a set of regional climate projections that have the systematic biases reduced. The dataset first utilized a statistical regression technique and a global reanalysis dataset to correct biases in the globally-simulated variables that are subsequently used to drive the regional model. The bias-corrected global simulation data led to a more realistic regional climate simulation of precipitation and associated atmospheric dynamics, as well as snow water equivalent (SWE) in comparison to the original globally-driven simulation. This …

Class-Based Interference Management In Wireless Networks, Mohammad Arif Hossain, Mostafa Zaman Chowdhury, Shakil Ahmed, Yeong Min Jang

Electrical and Computer Engineering Student Research

Technological advancement has brought revolutionary change in the converged wireless networks. Due to the existence of different types of traffic, provisioning of Quality of Service (QoS) becomes a challenge in the wireless networks. In case of a congested network, resource allocation has emerged as an effective way to provide the excessive users with desirable QoS. Since QoS for non-real-time traffic are not as strict as for real-time traffic, the unoccupied channels of the adjacent cells can be assigned to the non-real-time traffic to retain QoS for real-time traffic. This results in the intensified bandwidth utilization as well as less interference …

Neutral Density Behavior From 45-90 Km Based On Rayleigh Lidar Observations Above Usu, David Barton

Physics Capstone Projects

There are over 900 nights of observations taken by the Rayleigh lidar above Utah State University from 1993 to 2004. The data have been reduced to give absolute temperatures and relative densities in the mesosphere, from 45-90 km (Herron, 2004, 2007). From the 11 years of relative density data an 11-year climatology of mesospheric densities above Logan, Utah has been created. From this climatology I have been able to normalize the 11 years of density data to the following models: the MSISe00 empirical model, the CPC (Climate Prediction Center) reanalysis model, the ERA Interim reanalysis model, and the NASA MERRA …

Synthesis And Characterization Of Polymer (Sulfonated Poly-Ether-Ether-Ketone) Based Nanocomposite (H-Boron Nitride) Membrane For Hydrogen Storage, Naresh Muthu, S. Rajashabala, R. Kannan

Chemistry and Biochemistry Faculty Publications

The development of light weight and compact hydrogen storage materials is still prerequisite to fuel-cell technology to be fully competitive. The present experimental study reports the hydrogen storage capability of sulfonated poly-ether-ether-ketone (SPEEK)-hexagonal boron nitride (h-BN) (SPEEK-h-BN) nanocomposite membranes. The nanocomposite membranes are prepared by considering various amount of h-BN (0, 1, 3 and 5 wt. %) by phase inversion technique. The degree of sulfonation of the PEEK (SPEEK) is found to be 65% by Proton Nuclear Magnetic Resonance (¹H NMR) spectroscopy. Hydrogen adsorption studies have been carried out using a Seiverts-like hydrogenation setup. The membranes are characterized …

Developing, Implementing, And Evaluating A No-Child-Left-Inside Pilot Program, Claudia Radel, Jamie C. Brand, Roslynn Brain

Environment and Society Faculty Publications

We describe experience with a pilot week-long, No-Child-Left-Inside (NCLI), outdoor program implemented in Cache Valley, Utah, in 2012. Through response analysis of a “pre-then-post” children's survey and a parent-completed demographic survey, we assess program effectiveness in raising children's enthusiasm for nature-related behaviors and in reaching a target audience of all local families. The program reached many families with low participation in other conservation programs but failed to reach families from the growing Latino population. Participating children experienced increased excitement to spend more time outdoors exploring and learning, accomplishing NCLI goals of laying a groundwork for children's enhanced environmental literacy.

The Principle Of Reciprocity In Hospitality Contexts: The Relationship Between Tipping Behavior And Food Servers’ Approaches To Handling Leftovers, John S. Seiter, Harry Weger

Languages, Philosophy, and Communication Studies Faculty Publications

Based on the norm of reciprocity, this study hypothesized that food servers would earn higher tips when they boxed customers’ leftovers compared to having customers box leftovers themselves. In addition, the effect of writing messages (i.e., the date and/or customer’s name) on boxes of leftovers was explored. Two female food servers waited on 608 diners and boxed or did not box leftovers, and wrote or did not write messages on boxes. The hypothesis was supported. However, writing messages was not associated with tipping behavior.

Modeling The Snow Surface Temperature With A One-Layer Energy Balance Snowmelt Model, J. You, David G. Tarboton, C. H. Luce

Civil and Environmental Engineering Faculty Publications

Snow surface temperature is a key control on and result of dynamically coupled energy exchanges at the snow surface. The snow surface temperature is the result of the balance between external forcing (incoming radiation) and energy exchanges above the surface that depend on surface temperature (outgoing longwave radiation and turbulent fluxes) and the transport of energy into the snow by conduction and meltwater influx. Because of the strong insulating properties of snow, thermal gradients in snow packs are large and nonlinear, a fact that has led many to advocate multiple layer snowmelt models over single layer models. In an effort …

Grazing Exclosure Experiment On The Henry Mountains Of Southern Utah, Johan Du Toit, Dustin Ranglack

Browse all Datasets

The data contained herein are the results of a grazing exclosure experiment on the Henry Mountains of S. Utah [38°5’ N, 100°50’W] to determine the relative impacts of bison, cattle, and lagomorphs on forage availability. Exclosures were erected in October 2011 and the standing crop of grass inside both exclosure types (full and partial), as well as an open reference plot was clipped in October 2012. Additionally, the local ranching community was surveyed to measure their perceptions of the bison – cattle conflict in the Henry Mountains.
