Prognostic Value Of Elevated Serum Ceruloplasmin Levels In Patients With Heart Failure, Muhammad Hammadah, Yiying Fan, Yuping Wu, Stanley L. Hazen, W.H. Wilson Tang

Mathematics and Statistics Faculty Publications

Background: Ceruloplasmin (Cp) is a copper-binding acute-phase protein that is increased in inflammatory states and deficient in Wilson's disease. Recent studies demonstrate that increased levels of Cp are associated with increased risk of developing heart failure. Our objective was to test the hypothesis that serum Cp provides incremental and independent prediction of survival in stable patients with heart failure. Methods and Results: We measured serum Cp levels in 890 patients with stable heart failure undergoing elective cardiac evaluation that included coronary angiography. We examined the role of Cp levels in predicting survival over 5 years of follow-up. Mean Cp level …

Chaperone-Mediated Folding And Assembly Of Β-Propeller Proteins Into Cellular Signaling Complexes, Rebecca L. Plimpton

Theses and Dissertations

G protein signaling depends on the ability of the individual subunits of the G protein heterotrimer to assemble into a functional complex. Formation of the G protein βγ (Gβγ) dimer is particularly challenging because it is an obligate dimer in which the individual subunits are unstable on their own. Recent studies have revealed an intricate chaperone system that brings the Gβ and Gγ subunits together. This system includes the cytosolic chaperonin containing TCP-1 (CCT) and a co-chaperone phosducin-like protein 1 (PhLP1). Two key intermediates in the Gβγ assembly process, the Gβ-CCT and the PhLP1-Gβ-CCT complexes, were isolated and their structures …

So You Want To Produce Your Own Eggs?, Jacquie Jacob, Anthony J. Pescatore

Agriculture and Natural Resources Publications

Backyard chicken flocks are becoming popular throughout the country in urban, suburban and rural communities. Preparation is essential for a successful backyard flock.

Proper Handling And Transportation Of Eggs For Sale At Kentucky Farmers’ Markets, Anthony J. Pescatore, Jacquie Jacob

Agriculture and Natural Resources Publications

Regardless of the number of eggs produced, and whether the eggs are for home use or sale, careful egg handling is very important. The United States Food and Drug Administration (FDA) lists eggs as a potentially hazardous food, therefore careful handling is important. In Kentucky, if you sell more than 60 dozen eggs a week you need to purchase a retail license. The same holds true if you want to sell your eggs to a retail store to be re-sold or to a distributor that will sell them for you. If you produce fewer than 60 dozen eggs a week …

An Introduction To Sheep, Debra K. Aaron, Donald G. Ely

The information in this fact sheet was developed to provide a quick reference to the most frequently asked questions about sheep and sheep production.

Basic Sheep Genetics, Debra K. Aaron

Agriculture and Natural Resources Publications

Genetics is the science of heredity. It seeks to explain differences and similarities exhibited by related individuals. The application of genetics to livestock improvement is known as animal breeding. The objective of this fact sheet is to provide a refresher course on basic genetics and to show how knowledge of genetics can be used to improve sheep production.

Keeping And Using Flock Performance Records, Debra K. Aaron

Agriculture and Natural Resources Publications

Performance records serve as the cornerstone of any good livestock management program. Unfortunately, the task of collecting, maintaining and using performance records is the one area of livestock production in general that gets the least attention. This fact sheet provides ten reasons why all sheep producers need to keep performance records on their flocks. Then, some ways of maintaining and using those records are discussed.

Sheep Breeding: Heritability, Ebvs, Epds And The Nsip, Debra K. Aaron

Agriculture and Natural Resources Publications

Genetic improvement in a flock depends on the producer’s ability to select breeding sheep that are genetically superior for traits of economic importance. This is complicated by the fact that an animal’s own performance is not always a true indicator of its genetic potential as a parent.

Inbreeding In Sheep, Debra K. Aaron

Agriculture and Natural Resources Publications

Inbreeding is broadly defined as the mating of individuals that are related. Strictly speaking, however, all animals within a breed are related. So, in a sense, every purebred sheep producer practices some degree of inbreeding. In most cases this relationship is very slight. Therefore, inbreeding is more practically defined as the mating of individuals more closely related than the average of the breed. This practice includes mating brother to sister, sire to daughter and son to dam.

Crossbreeding Considerations In Sheep, Debra K. Aaron

Agriculture and Natural Resources Publications

Crossbreeding is the mating of individuals from different breeds. To a certain extent, it is a simple concept, but embarking upon a crossbreeding program, in sheep or any other livestock species, involves long-term decisions.

The primary benefits of a crossbreeding program are heterosis and breed complementarity.

Purschwitz, Larry D. Swetnam, John H. Wilhoit, Eric Walker, Steve Bost, Neil Rhodes, David Reed, Chuck Johnson, Loren Fisher, Matthew Vann, Scot Whitley, Mina Mila

Agriculture and Natural Resources Publications

Burley and dark tobacco growers in the U.S. make hundreds of decisions every growing season that impact the yield and quality of the crops that they produce. These decisions may include choosing appropriate varieties, planning effective pest control measures or perhaps deciding the best time to top or harvest a crop. Increasingly, tobacco growers are being required by the industry to record and justify their management decisions and actions. The most comprehensive example of this is the U.S. Tobacco Good Agricultural Practices (GAP) program that was initiated during the 2013 growing season and expanded in 2014. Under …

Pecci Code (Python Estimation For Carbon Concentration And Isotopes) For Calculating The Concentration And Stable Carbon Isotopic Composition Of Dissolved Inorganic Carbon (Dic) In Precipitation For Northwestern Arkansas, Katherine J. Knierim, Phillip D. Hays

Technical Reports

In karst settings, hydrograph separations using isotopic tracers are commonly and effectively used to quantify the proportions of rain rapidly delivered to springs along fractures and conduits during storm events. Dissolved inorganic carbon (DIC) is an effective, non‐conservative tracer for use in hydrograph separations of karst waters because of the ubiquitous nature of carbon in the sources of waters to caves and springs and unique concentrations and isotopic compositions of carbon inputs. DIC concentration and isotopic composition (δ¹³C‐DIC) in rain are typically calculated based on atmospheric carbon dioxide (CO₂) using equilibrium carbonate reactions and stable carbon isotope fractionation values. As …

Mind & Matter: The Discursive Construction Of The Iphone In Apple's Advertising, Nicholas Stratton

Theses and Dissertations

The widespread adoption of smartphone technology in the contemporary United States requires critical reflection on its role within society. This thesis compares the way Apple's television advertising discourse, from 2007 to 2011, frames the iPhone to consumers with the way Apple's iAd promotional material frames the iPhone to advertisers, and considers what the disparity between these two frameworks says about the still-evolving role of smartphone technology in society. It argues that the disparity between these two frameworks is indicative of a fundamental tension within smartphone technology. This tension is reflected in Apple's ability to discursively construct the iPhone as a …

Imaging, Spectroscopic, Mechanical And Biocompatibility Studies Of Electrospun Tecoflex® Eg 80a Nanofibers And Composites Thereof Containing Multiwalled Carbon Nanotubes, Javier Macossay-Torres, Faheem A. Sheikh, Travis Cantu, Thomas Eubanks, M. Esther Salinas, Chakavak S. Farhangi, Hassan Ahmad, M. Shamshi Hassan, Myung-Seob Khil, Shivani K. Maffi, Hern Kim, Gary L. Bowlin

Chemistry Faculty Publications and Presentations

The present study discusses the design, development and characterization of electrospun Tecoflex® EG 80A class of polyurethane nanofibers and the incorporation of multiwalled carbon nanotubes (MWCNTs) to these materials. Scanning electron microscopy results confirmed the presence of polymer nanofibers, which showed a decrease in fiber diameter at 0.5% wt. and 1% wt. MWCNTs loadings, while transmission electron microscopy showed evidence of the MWCNTs embedded within the polymer matrix. The fourier transform infrared spectroscopy and Raman spectroscopy were used to elucidate the polymer-MWCNTs intermolecular interactions, indicating that the C-N and N-H bonds in polyurethanes are responsible for the interactions with MWCNTs. …

Sensor-Free Corner Shape Detection By Wireless Networks, Yuxi Wang, Zimu Zhou, Kaishun Wu

Research Collection School Of Computing and Information Systems

Due to the rapid growth of the smartphone applications and the fast development of the Wireless Local Area Networks (WLANs), numerous indoor location-based techniques have been proposed during the past several decades. Floorplan, which defines the structure and functionality of a specific indoor environment, becomes a hot topic nowadays. Conventional floorplan techniques leverage smartphone sensors combined with WiFi signals to construct the floorplan of a building. However, existing approaches with sensors cannot detect the shape of a corner, and the sensors cost huge amount of energy during the whole floorplan constructing process. In this paper, we propose a sensor-free approach …

Effects Of Round Goby Presence On Invertebrate And Microbial Communities In Decaying Leaf Matter Of A Lake Erie Tributary Stream, Allyse M. Fischer

Biology Theses

Microbial communities are ubiquitous and carry out valuable functions in the environment. Decomposition of leaf material by microbial communities is important to return nutrients back to both terrestrial and aquatic organisms. Perturbations to the environment like the arrival of invasive species can have an impact on the structure and functions of the microbial community. The round goby (Neogobius melanostomus) is a Ponto-Caspian fish introduced into the Great Lakes which has since secondarily invaded tributary streams and rivers. Studies have shown they alter invertebrate communities, and these alterations have impacted organic matter decomposition. Stream studies suggest leaf litter decomposes …

Managing The Risks Of Shale Gas Development Using Innovative Legal And Regulatory Approaches, Sheila Olmstead, Nathan Richardson

William & Mary Environmental Law and Policy Review

Booming production of oil and gas from shale enabled by hydraulic fracturing technology has led to tension between hoped-for economic benefits and feared environmental and other costs, with great associated controversy. Studies of how policy can best react to these challenges and how it can balance risk and reward have focused on prescriptive regulatory responses and, to a somewhat lesser extent, voluntary industry best practices. While there is undoubtedly room for improved regulation, innovative tools are relatively understudied. The liability system predates environmental regulation yet still plays an important—and in some senses predominant—role. Changes to that system, including burden-shifting rules …

The 1852 Banda Arc Mega-Thrust Earthquake And Tsunami In Indonesia, Tsz Man Fisher

Theses and Dissertations

In 1852, a five-minute long earthquake hit the Banda Arc region that was felt over most of Indonesia. It caused uplift of new islands and sent a tsunami across the Banda Sea that reached a height of 8 meters at Banda Neira and was also registered at Ambon, Saparua and other islands. Records of the 1852 earthquake at multiple locations provide the constraints needed to reconstruct the disastrous event through earthquake intensity analysis and numerical modeling of the tsunami. Using tsunami heights and arrival times as the major constraints, best fit numerical models of the tsunami were constructed using Clawpack. …

Fabrication, Characterization, Optimization And Application Development Of Novel Thin-Layer Chromatography Plates, Supriya Singh Kanyal

Theses and Dissertations

This dissertation describes advances in the microfabrication of thin layer chromatography (TLC) plates. These plates are prepared by the patterning of carbon nanotube (CNT) forests on substrates, followed by their infiltration with an inorganic material. This document is divided into ten sections or chapters. Chapter 1 reviews the basics of conventional TLC technology. This technology has not changed substantially in decades. This chapter also mentions some of the downsides of the conventional approach, which include unwanted interactions of the binder in the plates with the analytes, relatively slow development times, and only moderately high efficiencies. Chapter 2 focuses primarily on …

Unusually Low Thermal Conductivity In The Argyrodite Ag8gete6 Attributed To Strong Anharmonicity, Dale Hitchcock

All Dissertations

Arguably the main focus of thermoelectric materials research over the last decade has been the reduction of lattice thermal conductivity through nanostructuring. This approach has proved quite effective in many instances, but has several inherent drawbacks including not only the metastability of many of the nanostructures used, but also difficulty decoupling the effects on the thermal properties of materials from the effects on their electrical properties. Some more recent research has focused on reduced thermal conductivity in materials with strong anharmonicity. In these systems anharmonicty in the crystal structure, whose strength can be gauged by the so-called Gruneissen parameter leads …

Majorana Fermions In Chiral Topological Superconductors, Eugen Florin Dumitrescu

All Dissertations

Majorana fermions were first proposed in the context of high energy physics by Ettore Majorana in 1937, just before his mysterious disappearance. Now, over 70 years later, signatures of condensed matter ana-logues of Majorana fermions are finally appearing in low-dimensional superconductor-based heterostructures. In low-dimensional systems, these order parameter, defect-bound Majorana quasiparticles obey non-Abelian quantum statistics and can therefore be used as the building blocks of a topological quantum computer. In this thesis we will analyze the signatures associated with, and the robustness of, Majorana bound states in a variety of one-dimensional superconducting platforms. Our main result is the finding that …

An Approximation Algorithm For The Stable Marriagae Problem With Ties And Incomplete Lists, Rommel Jalasutram

All Dissertations

Consider the bipartite matching problem with two sets of participants: men (L) and women (R). Each person participating has a strict and complete preference list over participants from the other set. The goal is to pair men and women such that no one can improve their partner by breaking away from the centralized matching scheme. Problems that exhibit this flavor are commonly classified as ordinal matchings. Gale and Shapley showed how to obtain such a matching (otherwise known as a “stable” matching). Generalizations of this model have found relevance in several centralized matching schemes such as the National Residency Matching …

Generalizing Cantor-Schroeder-Bernstein: Counterexamples In Standard Settings, Tien Chih

The Mathematics Enthusiast

The Cantor-Schroeder-Bernstein theorem states that any two sets that have injections into each other have the same cardinality, i.e. there is a bijection between them. Another way to phrase this is if two sets A;B have monomorphisms from A to B and B to A, then they are isomorphic in the setting of sets. One naturally wonders if this may be extended to other commonly studied systems of sets with structure and functions which preserve that structure. Given two objects with injective structure preserving maps between them are the structures of these objects the same? In other words, would these …

Math As A Tool Of Anti-Semitism, Jay Egenhoff

The Mathematics Enthusiast

At Moscow State University’s Department of Mathematics during the 1970’s and 1980’s, there was rampant discrimination against Jewish and other unwanted students. The professors at the math department made a strong effort to keep Jewish students out of the department. They designed "killer" or "coffin" problems and Jewish students had to answer them during an oral exam. These problems have simple solutions, but require a clever strategy to solve them. This paper explores some of the context of this episode and provides several problems with detailed solutions.

Scholastic Standards In The United States – The Discussion Concerning The ‘Common Core’, Alan H. Schoenfeld, Günter Törner

The Mathematics Enthusiast

Preface: This article has been developed based on a personal discussion between the German author Günter Törner and Alan Schoenfeld, who is an expert in the field of mathematical didactics. Basically there are three reasons for us to share our insights with the public:

(1) Readers, having subscribed to Jerry Becker’s e-mail information network, have received numerous messages over the past few months; what do we need to know about this fact in Germany?

(2) Scholastic standards – a keyword that sounds very familiar to us in terms of educational policy… But it is also a hot topic in other …

Book Review Of The Tower Of Hanoi: Myths And Maths (Birkhäuser), Cory Palmer

The classic Tower of Hanoi puzzle along with a number of its variations and related puzzles are examined in a rigorous mathematical framework.

The Existence Of A Discontinuous Homomorphism Requires A Strong Axiom Of Choice, Michael Steven Andersen

Theses and Dissertations

Conner and Spencer used ultrafilters to construct homomorphisms between fundamental groups that could not be induced by continuous functions between the underlying spaces. We use methods from Shelah and Pawlikowski to prove that Conner and Spencer could not have constructed these homomorphisms with a weak version of the Axiom of Choice. This led us to define and examine a class of pathological objects that cannot be constructed without a strong version of the Axiom of Choice, which we call the class of inscrutable objects. Objects that do not need a strong version of the Axiom of Choice are scrutable. We …
