Turkish Journal of Veterinary & Animal Sciences

Ovine scrapie is considered a neurodegenerative disease characterized by the accumulation of an abnormal, protease-resistant isoform of PrP. The polymorphisms at codons 136, 154, and 171 are associated with susceptibility to scrapie. In order to detect the existing polymorphisms at the 3 codons we used the real-time PCR technique. The obtained genotypes were confirmed by PCR amplification and sequencing of a 402 bp fragment of exon 3 of the prion gene. Known polymorphisms were detected at codons 136, 154, and 171 and 5 different genotypes were determined. The results showed that all animals were homozygous for A at codon 136 …

Comparative Imaging Study In Ultrasound Mri, Ct And Dsa Using A Multi-Modality Renal Artery Phantom, Deirdre King, Andrew Fagan, Carmel Moran, Jacinta Browne

Articles

A range of anatomically-realistic multi-modality renal artery phantoms consisting of vessels with varying degrees of stenosis was developed and evaluated using four imaging techniques currently used to detect renal artery stenosis (RAS). The spatial resolution required to visualize vascular geometry and the velocity detection performance required to adequately characterize blood flow in patients suffering from RAS is currently ill-defined, with the result that no one imaging modality has emerged as a gold standard technique for screening for this disease.

Methods: The phantoms, which contained a range of stenosis values (0, 30, 50, 70 and 85%), were designed for use with …

Increased Tolerance To Abiotic Stresses In Tobacco Plants Expressing A Barley Cell Wall Peroxidase, Philippe Pringuet, Norman Mcmillan, Greg Doyle, Stephen Smith, Sebastian Riedel

Articles

Tensiography is a technique that determines the physical and chemical properties of a liquid by illuminating a growing pendant drop from within using a source fibre. Light reflected internally at the surface of the drop is recieved by a collector fibre and is converted into an electric signal called a tensiotrace, which is a graph of reflected light as a function of drop volume. The instrument obtaining this signal is called multianalyser. A numerical model that simulates tensiotraces through a raytracing analysis (RAST - Raytracing Analysis for the Simulation of Tensiotraces) of the multianalyser as been developed to define theoretically …

A decavanadate/chitosan complex was synthesized by crosslinking chitosan with decavanadate anions at a pH of 3. The materials were characterized by Fourier transformed infrared spectroscopy (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), absorption spectroscopy (UV-Vis), and transmission electron microscopy (TEM). The spectroscopic results indicated that the decavanadate/chitosan complex was successfully obtained as result of an ionic crosslinking of the chitosan with decavanadate anions.

Assimilable Organic Carbon Generation From Algogenic Organic Matter In Drinking Water, Ji-Hoon Kim, Young-Ju Kim, Tahir Imran Qureshi

Turkish Journal of Chemistry

A study of assimilable organic carbon (AOC) derived from algogenic organic matter in different drinking water resources was conducted. Seasonal changes in the concentration of AOC at Kamafusa Dam were dependent on the algal cell numbers. Variations in AOC concentrations were found to be more reliant on the AOC-P17 component than the AOC-NOX component. The algal culture experiment showed that extracellular organic matter (EOM) released during the growth of Phormidium tenue in M-11 culture medium led to a significant increase in AOC concentration; however, no significant variations of AOC concentration were observed in CT culture medium containing high amounts of …

Mcdonald V. Chicago, Self-Defense, The Right To Bear Arms, And The Future, Richard Aynes

Akron Law Faculty Publications

This article examines the opinion of the Court in McDonald v. Chicago and its implications for the future. The author participated as a party-amicus in the case and an article he authored in 1993 was cited by the Court.

Using a concept that others have applied in other situations, this paper suggests that Chicago was a “outlier” and that this case simply involved reigning in a maverick outlier. While the paper finds Justice Thomas’s concurring opinion (with the exception of dicta on the establishment clause) being the most faithful to the meaning, intention, and public understanding of the 14th Amendment, …

Leading Unconducted Chamber Vocal Ensembles: A Case Study Of The University Of Northern Iowa Varsity Men's Glee Club Camerata, David Hoobler

Honors Program Theses

Recently, unconducted chamber vocal ensembles have emerged as one of, if not the most popular forms of vocal performing groups. TV shows such as "The Sing Off' and "Glee" showcase the musical abilities of this type of ensemble. Barbershop quartets enjoy high levels of popularity. Professional groups such as Voces8 and other groups on many college campuses are constantly in demand for performances. In addition, educators find it necessary to learn how to lead these groups especially in the state of Iowa where quartets are used for All-State auditions, and the popularity of Show Choir necessitates an unconducted vocal ensemble …

The Diffusion Of Microgeneration Technologies.: Assessing The Influence Of Perceived Product Characteristics On Home Owners’ Willingness To Pay, Marius Claudy, Claus Michelsen, Aidan O'Driscoll

Articles

This study presents empirical insight into willingness to pay (WTP) for microgeneration technologies and the relative influence of subjective consumer perceptions. First, we apply a double-bounded-contingent valuation method to elicit Irish home owners’ willingness to pay for micro wind turbines, wood pellet boilers, solar panels and solar water heaters. Utilizing findings from the adoption of innovation literature, in a second step, we assess the influence of different antecedents on WTP for each of the four technologies, including (1) home owners’ perception of product characteristics, (2) normative influences, and (3) socio demographic characteristics. Our results show that WTP varies significantly between …

The New Old Legal Realism, Mitu Gulati, Tracey E. George, Ann Mcginley

Faculty Scholarship

Do the decisions of appellate courts matter in the real world? The American judicial system, legal education, and academic scholarship are premised on the view that they do. The authors want to reexamine this question by taking the approach advocated by the original Legal Realists. The current project seeks to add to our knowledge of the relevance of case law by focusing on an area that has received little examination: how pronouncements about employment discrimination law by appellate courts translate into understandings and behavior at the ground level. As our lens, we use evidence of how people talk about the …

Using Handheld Touch Screen Enabled Devices And Persuasive Game Mechanics To Teach Quadratic Functions, Alejandro Montoya

Technical Library

Research has shown that many students are not interested in learning mathematics; they find it difficult to understand, irrelevant to their daily lives, and uninteresting. This thesis explores elements of computer games that may satisfy children’s learning needs and ultimately motivate them to learn mathematical concepts.

According to a 2008 survey conducted by the Washington, D.C. based Pew Research Center, 97% of children between the ages of 12 and 17 in the United States play computer, Web, portable or console games. Based on these numbers we can conclude young students like video games. Over the past few years, a new …

Charities And Lobbying: Institutional Rights In The Wake Of Citizens United, Lloyd Hitoshi Mayer

Journal Articles

One of the many aftershocks of the Supreme Court’s landmark decision in Citizens United v. FEC is that the decision may raise constitutional questions for the long-standing limits on speech by charities. There has been much scholarly attention both before and after that decision on the limit for election-related speech by charities, but much less attention has been paid to the relating lobbying speech limit. This article seeks to close that gap by exploring that latter limit and its continued viability in the wake of Citizens United. I conclude that while Citizens United by itself does not undermine the limit …

Localism And Capital Punishment, Stephen F. Smith

Journal Articles

Professor Adam Gershowitz presents an interesting proposal to transfer from localities to states the power to enforce the death penalty. In his view, state-level enforcement would result in a more rationally applied death penalty because states would be much more likely to make capital charging decisions based on desert, without the distorting influence of the severe resource constraints applicable to all but the wealthiest of localities. As well conceived as Professor Gershowitz’s proposal is, however, I remain skeptical that statewide enforcement of the death penalty would be preferable to continued local enforcement. First, Professor Gershowitz underestimates the benefits of localism …

The Political (And Other) Safeguards Of Religious Freedom, Richard W. Garnett

Journal Articles

This essay is a contribution to a symposium marking the 20th anniversary of the Supreme Court’s still-controversial decision in Employment Division v. Smith. That decision, it is suggested, should not be read as reflecting or requiring hostility or indifference towards claims for legislatively enacted accommodations of religion. Smith is not an endorsement of religion-blind neutrality in constitutional law; instead, it assigns to politically accountable actors the difficult, but crucially important, task of accommodating those whose religious exercise would otherwise be burdened by generally applicable laws. The essay goes on to suggest several things that must be true of our law …

The Self-Judging Wto Security Exception, Roger P. Alford

Journal Articles

This Article analyzes the WTO security exception, with a particular focus on State practice. In the absence of any GATT or WTO jurisprudence, State practice affords the best vehicle to understand the meaning of Article XXI. In the few instances when invocation of the security exception has been challenged, State practice suggests that the security exception is not judicially reviewable.

A critical question emerges from this analysis of State practice. If a Member State can avoid WTO obligations through a self-judging security exception, what is to prevent bad faith invocations? The WTO regime includes a number of devices to address …

Strategic Spillovers, Daniel B. Kelly

Journal Articles

The conventional problem with externalities is well known: Parties often generate harm as an unintended byproduct of using their property. This Article examines situations in which parties may generate harm purposely, in order to extract payments in exchange for desisting. Such “strategic spillovers” have received relatively little attention, but the problem is a perennial one. From the “livery stable scam” in Chicago to “pollution entrepreneurs” in China, parties may engage in externality-generating activities they otherwise would not have undertaken, or increase the level of harm given that they are engaging in such activities, to profit through bargaining or subsidies. This …
