'Lacefield Maxqll' Novel Tall Fescue, Timothy D. Phillips

Kentucky Grazing Conference

The goal of deploying novel endophyte strains in tall fescue varieties has been to achieve forage yields, stress tolerance, and persistence similar to toxic endophyte tall fescue varieties (mainly ‘Kentucky 31’ endophyte infected with the common toxic endophyte strain), but with the superior animal performance results seen with endophyte-free tall fescue varieties or other non-toxic forage species (orchardgrass, alfalfa, etc.). In addition to better stand persistence, less weed encroachment has been reported in novel endophyte (and toxic endophyte) tall fescue varieties compared to their endophyte-free versions (Rudgers et al., 2010; Bouton et al., 2002). The improved competitive ability of endophyte-containing …

Soy Hulls: More Than Just A Feed Supplement, Glen E. Aiken, Michael Flythe

Kentucky Grazing Conference

There is approximately 35 million acres of tall fescue in the USA, with most of this acreage being utilized in hay meadows and grazed pastures in a region between the temperate northeast and subtropical southeast and commonly referred to as the Fescue Belt. Popularity of the grass is due to its productivity, persistence, and low cost of management. Unfortunately, a fungal endophyte that infects most plants of tall fescue produces ergot alkaloid toxins that cause a toxicosis in cattle and other grazing livestock. Fescue toxicosis may reduce reproductive performance of cow herds and weaning weights, and reduce post-weaning weight gain …

The Secret Ingredients Of Clover: Biochanin A And Isoflavonoids, Michael Flythe, Glen Aiken, Isabelle Kagan

Kentucky Grazing Conference

It is well known that the value of clover is in nitrogen. Clovers fix their own nitrogen so that an input of nitrate fertilizer is not required. Furthermore, they are rich in protein-nitrogen, and can be used to meet the protein requirements of ruminants. Clovers also contain a class of chemicals called isoflavones, and we have recently discovered evidence that the isoflavones positively influence the way that ruminants digest protein.

A method and apparatus are disclosed for approximating in real time the fracture fatigue entropy (FFE) of a metallic object subjected to cyclic loading. Such objects experience fatigue, which can lead to failure after a number of loading cycles. The disclosed invention allows for real time monitoring of the entropy increase in a metallic object under cyclic loading, and allows for removing the object from service before fatigue fracture occurs. Through use of the present invention, users may keep metallic objects in service for longer periods, because such objects may be safely taken closer to the fatigue fracture point. The …

Using Accelerometer Data To Remotely Assess Predation Activity Of Arctic Wolves (Canis Lupus Arctos), Heather Shipp

Research on Capitol Hill

Arctic wolves (Canis lupus arctos) play an important role in ecosystems located in the far northern regions of the world; however, little information is available about them and their impacts on prey populations due to their remote location. Recently, there has been concern about declining caribou populations, which serve as an important food source for local Inuit peoples. As a result, there is an urgent need to better understand Arctic wolves and their influence on caribou abundance.

Dr. Dan MacNulty, a professor at Utah State University, is currently conducting research on Arctic wolves in the Fosheim Peninsula of Ellesmere Island, …

Stomatal Differences In Western Aspen And Linkage To Drought Tolerance, Brianne Palmer

Research on Capitol Hill

Aspen are the most widely distributed broadleaf tree in North America .However, aspen mortality is widespread across the Intermountain West. Researchers are attempting to determine the causes of the decline and propose future methods of management.

In order to survive, plants need to take in CO₂ through pores on their leaves called stomata. When the stomata are open, the plant takes in CO₂, however, water escapes. Therefore, stomata are important in regulating the drought response in plants. The size and the density of the stomata could influence the drought tolerance of an organism.

In Utah, there are …

Sexual Assault And The Doctrine Of Chances In The Courtroom, Ryan Wallentine

Research on Capitol Hill

Sexual assault can have devastating and long-lasting effects on victims, but many assailants get away with their crime without being prosecuted.

The doctrine of chances is a rule of evidence allowing evidences of past crimes, wrongs, or acts to show it is unlikely a defendant would be repeatedly and innocently involved in similar, suspicious circumstances.

Given that about 63.3% of assailants are repeat offenders, the doctrine of chances could effectively be used in sexual assault cases.

The main objective is to determine a precise probabilistic threshold for allowing the use of the doctrine of chances in sexual assault cases such …

Potential Regulation Of Deadly Water-Borne Shigella Bacteria Pathogenesis Through The Shigella Infection Protein Spa47, Jamie Kingsford

Research on Capitol Hill

• Shigella is a gram-negative, bacterial pathogen typically found in contaminated water sources.
• Each year, Shigella is responsible for over 90 million infections and 100,000 deaths stemming from symptoms of severe dysentery, fever, nausea and vomiting.
• A needle-like apparatus found on the surface of Shigella allows the bacterium to infect host cells.
• Each needle-apparatus has an associated ATPase, a protein that can hydrolyze ATP into ADP and P_i.
• The Shigella needle-apparatus ATPase Spa47 is predicted to provide the energy for infection.
• Spa47 has been shown to be essential for infection – without Spa47, no infection will occur.
• We were …

Conformal Symmetry: Finding New Physics In Scale Invariance, Benjamin C. Lovelady

Research on Capitol Hill

Modern physics is the study of symmetry. Everything from electromagnetism to the famed Higgs mechanism stems from fundamental symmetries. These have fancy mathematical names and even fancier math behind them, but the basic idea is the same. These are mathematical generalizations of normal transformations such as rotating. These symmetries describe fields (electric, magnetic, etc.).

Most models of unification, i.e. string theory, use "Poincare symmetry." This symmetry includes both translations and rotations. This means physics only cares about relative position, angle, velocity, etc. If I were to wake up in a windowless room that had been moved a mile north and …

Water Use Of Kentucky Bluegrass Varieties, Shawn Foster

Research on Capitol Hill

• With drought so prevalent in the West, water use on urban landscapes is being closely scrutinized with up to 60% of urban water use directed to landscape irrigation-primarily our lawns.
• Kentucky bluegrass (Poa pratensis L.) is widely used because of its soft texture, attractive color, and ability to recover from intensive use.
• More water-efficient varieties of Kentucky bluegrass may result in less irrigation yet maintain quality and function of the turf.

Software Interoperability And The Pods Openhds System, Benjamin S. Heasly Ms

All Student Scholarship

This work addressed challenges of software system interoperability faced by the Open Health and Demographics Surveillance System (OpenHDS). OpenHDS is a distributed application for demographic data collection which was used during a public health intervention in Equatorial Guinea. Specific challenges faced during this intervention included offline data collection and synchronization, changing data collection and software requirements, data size and system performance, and correction of software and data collection errors. This work produced in a new system, the PODS OpenHDS System, which applied four design themes in order to address these challenges: Polymorphism, developer Operations, Declarative style, and Self-description.

Using Digital Stories And Ipads To Promote Writing Skills, Writing Self-Efficacy, And Motivation To Write Among 9th Grade Students, Anthony J. Girasoli

Doctoral Dissertations

This study explores the use of digital storytelling as a prewriting activity to help 9^th grade students plan narrative essays in English writing lessons. Students (N = 62) in three course sections taught by the same teacher completed a 10-week intervention. Each section was assigned to one of three groups according to their learning environment: a normal educational practice (NEP) group, a bulletin board system (BBS) group, and an asynchronous audio/video (AAV) group. The BBS and AAV groups created digital stories to plan their narratives while the NEP group developed written outlines.

Chapter 2: Time Series, Sara A. Myers

Journal Articles

Time series is “simply a list of numbers assumed to measure some process sequentially in time” (Stergiou et al. 2004). Mathematicians have a more formal definition, that is, a set or a sequence of observations, with each one recorded at specific times, or at least sequentially (Brockwell and Davis 2002; Box et al. 2008). Time series are created from multiple sources for research purposes to understand various behaviors. For example, social scientists could collect graduation rates, physiologists record heart rates, economists study consumer spending, and climatologists examine weather patterns. Basically, any time observations are taken repeatedly over time, from any …
