Engendering Meaning Within The High School Experience: A Consideration Of Movement And Dance, Stephanie A. Morris
Graduate Theses, Dissertations, and Problem Reports (ETD)
Dance, movement, and kinesthetic learning are among the most powerful ways in coming to know, yet they are amid the most ignored processes at the high school level. Dance has the power to change lives as it offers aesthetic ways of viewing and connecting with the world through its creative, reflective, and imaginative embodied experiences. I have observed these valuable outcomes and address the nature and power of them with the following questions: (1) How has dance and movement influenced my journey? (2) How has this influence affected the high school experience of my students? The heuristic method of qualitative …
Listeria Survival After Isoelectric Solubilization And Precipitation Of Fish Protein With Organic Acids, Rachel Otto
Listeria Survival After Isoelectric Solubilization And Precipitation Of Fish Protein With Organic Acids, Rachel Otto
Graduate Theses, Dissertations, and Problem Reports (ETD)
With mechanical fish processing, a substantial amount of protein is discarded as byproducts. Isoelectric solubilization and precipitation (ISP) is a process that recovers previously discarded protein using extreme pH shifts to solubilize and precipitate protein from byproducts. Typically, strong acids are used for pH reduction but have limited impact on bacterial load; therefore, organic acids were used during ISP processing to test the impact on Listeria ssp. concentrations. The goals of these studies were to determine the effectiveness of organic acids, specifically acetic and citric acids, to reduce L. innocua during the protein recovery process of ISP and to determine …

Role Of Protein Kinase Ck2 And Phosphatase Pp2a In Notch-Mediated Lateral Inhibition, Anasua Bose
Role Of Protein Kinase Ck2 And Phosphatase Pp2a In Notch-Mediated Lateral Inhibition, Anasua Bose
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Notch signaling pathway is highly conserved in vertebrates and invertebrates and regulates binary cell fate specifications in diverse developmental contexts. In a process termed lateral inhibition, Notch signaling restricts a particular cell fate to a single cell from a group of multi-potential cells. This mechanism ensures precision in cell fate assignations, which are vital for histogenesis and organogenesis. Studies during Drosophila neurogenesis, specifically development of the compound eye and the mechanosensory bristles, have provided the most detailed insights into the underlying mechanisms. During this process, Notch signaling results in the selection of single R8 photoreceptors or bristle sensory organ …

Eastern Hemlock Tsuga canadensis is a coniferous tree native to eastern North America. It ranges from northeastern Minnesota eastward through southern Quebec, and from the southern Appalachian Mountains to northern Georgia and Alabama.;This majestic tree is threatened with elimination by an invasive species Hemlock Woolly Adelgid (HWA) Adelges tsugae introduced in the USA in 1924, which is believed to be a native of Asia. HWA reduces shoot growth, provokes branch dieback, and eventually tree death.;One strategy to help mitigate the fast spread of HWA is to determine what may cause host potential resistance to HWA and how to use this …
You Are And You Ain't: Redneck Literature And The Imposition Of Identity, Matthew Joseph Ferrence
You Are And You Ain't: Redneck Literature And The Imposition Of Identity, Matthew Joseph Ferrence
Graduate Theses, Dissertations, and Problem Reports (ETD)
Redneck images pervade contemporary American culture and provide a pattern for national behavior. As globalization and multiculturalism change the demographics of the nation, covert Redneck codes enforce previous hegemonies of race, class, and gender. Imbued with incontestable American character, the Redneck becomes an ideological force capable of defending the nation from destabilizing cultural incursions. The maintenance of these Redneck codes relies on the continued reassertion of Southern and Appalachian stereotypes, since these regions must be maintained as authentic homelands for the identity character.;In this project, I locate a literary genealogy for the American Redneck and examine the roots and function …

A Ten-Year Evaluation Of Structural And Compositional Development In Unmanaged Central Appalachian Clearcuts, Jonathan R. Marden
A Ten-Year Evaluation Of Structural And Compositional Development In Unmanaged Central Appalachian Clearcuts, Jonathan R. Marden
Graduate Theses, Dissertations, and Problem Reports (ETD)
The varied growing conditions, fractured topography, and diversity of woody species in the Central Appalachians ensure that the harvest response of forest stands in the region will never be easily predictable. Clearcutting exposes the seedbed and freshly cut stumps of a harvested forest to full sunlight, encouraging the regeneration of the greatest number of species possible for that region. Gathering information on stand response to a complete removal in the mixed mesophytic forests of West Virginia will add valuable information to the silvicultural database for the most complex hardwood ecosystem in North America.;Beginning in 1998, U.S. Forest Service personnel installed …

The Effects Of A Phytogenic Feed Additive Versus An Antibiotic Feed Additive On Oxidative Stress In Broiler Chicks And A Possible Mechanism Determined By Electron Spin Resonance And The Effect Of Allopurinol, Uric Acid Sodium Salt Administration, And Inosine On Xanthine Oxidoreductase Activity And Plasma Uric Acid In Broilers., Tabatha L. Settle
Graduate Theses, Dissertations, and Problem Reports (ETD)
The purpose of the first study was to compare a phytogenic feed additive and an antibiotic feed additive when measuring oxidative stress in young broilers. Phytogenic feed additives are plantderived products used in poultry feeding to improve overall performance of broilers. Although the precise mechanism by which the increased growth rate is realized remains uncertain, these products have antioxidant components that are known to reduce oxidative stress. This is considered important in that reactive oxygen species (ROS), the causative factor of oxidative stress, can result in damage to biological systems within the bird. In this study, 588 one day-old Cobb …

Regulation Of Anoikis By Ankyrin Complexes, Sanjeev Kumar
Graduate Theses, Dissertations, and Problem Reports (ETD)
Anoikis is a subset of apoptosis, suppressed by cell-extracellular matrix association. It is a safeguard mechanism against tumor metastasis. The present study was designed to understand the role of cortical cytoskeletal protein ankyrin-G and its interacting proteins in anoikis. E-cadherin and ankyrin-G are function partners and during epithelial-mesenchymal-transition (EMT), both gets downregulated. During cell-extracellular matrix dissociation, ankyrin-G shifts to cytoplasm from cytoskeleton and loses spectrin interaction. Overexpression of ankyrin-G induced apoptosis in death domain dependent manner, promoted by the presence of ankyrin-G death domain interacting partner, RIP1 (Receptor Interacting Protein with death domain). Ankyrin-G also interacted with a MAGE family …

Characteristics Of Subordinate Follicles Following Removal Of The Dominant Follicle: Induction Of Selection, Matthew Dean
Characteristics Of Subordinate Follicles Following Removal Of The Dominant Follicle: Induction Of Selection, Matthew Dean
Graduate Theses, Dissertations, and Problem Reports (ETD)
In mammals, ovarian follicles begin as primordial follicles. Over time these follicles are gradually activated and begin growth. As they proceed, granulosal and thecal cells are acquired. Eventually, the follicles become dependent on FSH for survival. Two or three times each cycle, a transient increase in FSH allows a cohort of follicles, including the follicle that will ovulate, to continue growing. However, these follicles secrete inhibin and estradiol, which suppress FSH secretion. Eventually, all the follicles of the cohort undergo atresia due to the declining concentrations of FSH, except for the follicle which has the potential to ovulate. This follicle …

Optimization Of A Retrofit Urea-Scr System, Clinton R. Bedick
Graduate Theses, Dissertations, and Problem Reports (ETD)
Oxides of nitrogen (NOx) emissions from legacy diesel engines are often many times over currently mandated standards, contributing significantly to degradation of air quality and negative environmental impact. A retrofit urea-SCR (selective catalytic reduction) aftertreatment system offers a viable solution for reducing NOx emissions from older diesel engines. A stand-alone retrofit urea-SCR aftertreatment system was previously developed by West Virignia University (WVU) engineers, implementing a pre-SCR NOx sensor, open-loop feed-forward control, and stoichiometric NOx reduction logic. During experimental testing at WVU, the urea-SCR system demonstrated NOx reductions of 2% to 53%, depending on the test cycle. In order to optimize …
The Fearful Face And Beyond: Fmri Studies Of The Human Amygdala, Jillian E. Hardee
The Fearful Face And Beyond: Fmri Studies Of The Human Amygdala, Jillian E. Hardee
Graduate Theses, Dissertations, and Problem Reports (ETD)
The amygdala has been labeled as a "detector of threat", evidenced by its heightened response to fearful faces in human neuroimaging studies. A critical element of the fearful face is an increase in eye white area, hypothesized to be crucial for the rapid detection of fear in another's face. Yet other facial expressions can also increase eye white area in a manner that is similar (a lateral shift in gaze) or identical (surprise) to fear. It is unknown if the amygdala can differentiate between these types of increases in eye white area and those that are specifically associated with fear …
