Microalgae And Zinc Source Supplementation Of Broiler Breeder Diets Affects Broiler Breeder Skeletal Development And Reproduction With Transgenerational Impacts On Offspring Performance And Skeletal Characteristics, Marquisha A. Paul

Theses and Dissertations--Animal and Food Sciences

Leg problems and disorders are of major concern for the poultry industry and animal welfare. Previous studies suggest that it may be possible to improve skeletal characteristics through nutrition. Omega-3 fatty acids, including Docosahexaenoic acid (DHA), are essential nutrients and are known to play an important role in bone tissue development. FORPLUS™ (Alltech, Inc.) is an unextracted, whole-cell microalgae (Aurantiochytrium limacinum CCAP 4087/2) that contains 64% fat and 16% DHA. Zinc (Zn) is a trace element and essential nutrient for growth and skeletal development. Bioplex^® Zn (Alltech, Inc.) is a Zn proteinate that has been shown to be …

Essays On Investments, Michael Farrell

Theses and Dissertations--Finance and Quantitative Methods

The first chapter studies mutual funds. I model intraquarter trading and use a genetic algorithm to estimate the trade pattern that is most consistent with the fund's daily reported returns. I validate the model empirically on a sample of institutional trades from Ancerno and I confirm that the method more accurately predicts daily holdings when compared to existing naive assumptions. Further, my method is substantially more accurate in classifying a fund's tendency to supply liquidity, and this increased precision has important implications for identifying superior performing funds. Specifically, a long-short strategy based on the model's liquidity provision measures earns significant …

Understanding The Structure-Property-Performance Relationship Of Silicon Negative Electrodes, Jiazhi Hu

Theses and Dissertations--Chemical and Materials Engineering

Rechargeable lithium ion batteries (LIBs) have long been used to power not only portable devices, e.g., mobile phones and laptops, but also large scale systems, e.g., electrical grid and electric vehicles. To meet the ever increasing demand for renewable energy storage, tremendous efforts have been devoted to improving the energy/power density of LIBs. Known for its high theoretical capacity (4200 mAh/g), silicon has been considered as one of the most promising negative electrode materials for high-energy-density LIBs. However, diffusion-induced stresses can cause fracture and, consequently, rapid degradation in the electrochemical performance of Si-based negative electrodes. To mitigate the detrimental effects …

A Singer’S Stress: Yoga And Meditation Techniques In The Collegiate Voice Studio, Zackery David Morris

Theses and Dissertations--Music

Often neglected in voice study is the understanding that a singer’s instrument lives in his/her body and therefore cannot be packed away like other musical objects. Yoga and mindfulness compliment the belief of a whole body instrument. Data gathered on college campuses report that stress and anxiety are on the rise, thus reinforcing the need for MBSR and yoga as beneficial and proven tools for stress relief. The current state of research in the realm of mental health in colleges merits the study of a cohesive layout of these exercises and their expected outcomes in singing as well as stress …

Finding The “Tech” In Technique: A Pedagogical Approach To Electroacoustic Concert Percussion Performance Practice, William Brady Harrison Ii

Theses and Dissertations--Music

Premise and Objectives

In our increasingly technology driven society, the impact of technology touches nearly every aspect of our lives in some form or another. This has been acutely felt within the world of percussion, with electroacoustic works representing perhaps the most rapidly expanding area of concert percussion over the last twenty years. Electroacoustic music couples electronic technology with traditional acoustic instruments and/or performance practices.

Broadly, this paper outlines a systematic approach to teaching electroacoustic performance practice, based on elements found in a cross-section of percussion literature. In using such an approach, not only does each student become more capable …

Identity, Spectacle, And Embodiment In Social Protest, Craig Alan Crowder

Theses and Dissertations--English

This dissertation examines the way rhetorical performances of identity function within a social movement. Examining the University of Kentucky chapter of a campus activist organization, United Students Against Sweatshops, I argue that embodied performances of identity often leverage spectacle in disruptive ways and work not only to solidify activists’ identities as part of a social movement but ultimately help to create solidarity within the movement, thereby working toward movement objectives. Historically under-examined in social movement literature in the rhetoric and composition tradition, identity performance examples are taken from an oral history project and archival materials to show how identity is …

Effects Of Curcumin And Fenugreek Soluble Fiber Supplements On Submaximal And Maximal Aerobic Performance Indices In Untrained College-Aged Subjects, Jensen Goh Zhong Sheng

Theses and Dissertations--Kinesiology and Health Promotion

Submaximal exercise performance is, in part, limited by the accumulation of metabolic byproducts and energy system capacities. Curcumin and the combination of curcumin and fenugreek soluble fiber (CurQfen^®) have been shown to increase endogenous antioxidants and metabolic byproduct clearance as well as reduce inflammation and lipid peroxidation, and therefore, may enhance submaximal aerobic thresholds. In addition, there is evidence that the galactomannan component of fenugreek, used to enhance bioavailability of curcumin, may also have potential physiological effects related to the up regulation of free fatty acid oxidation Therefore, the purpose of this study was to examine the effects …
