Further Characterization Of A Secreted Lipase From The Human Pathogen Leishmania Donovani By Determining The Effect Of Various Metal Ions On Its Enzymatic Activity., Lana Hoertz

Pell Scholars and Senior Theses

Leishmania donovani, a protozoan parasite, is the causative agent of the often fatal disease visceral leishmaniasis. The current treatments available are minimal and toxic to the patient. It has been shown that these organisms exhibit lipolytic activity during their growth in vitro. Lipases are enzymes that are known to aid in the development and virulence of several pathogenic organisms such as Candida albicans and Staphylococcus warneri. Little information is known, however, about the role of lipases in Leishmania species. We hypothesize that lipase may play a part in Leishmania's ability to survive within the human host as well as its …

The Judge’S Hold: A Struggle For Voice In Cormac Mccarthy’S Blood Meridian, Daniel R. Johnson Jan 2014

The Judge’S Hold: A Struggle For Voice In Cormac Mccarthy’S Blood Meridian, Daniel R. Johnson

Pell Scholars and Senior Theses

Cormac McCarthy's Blood Meridian is a novel that provides a clear critique on the ways in which the American west was acquired. The text is awash with gratuitous violence, symbolism and storytelling, together creating a piece that offers a modern interpretation of American identity. This analysis will approach the novel by examining a struggle for voice between the two main characters Judge Holden and The Kid in the narration. In doing so, it will be shown that Blood Meridian uses Holden's voice to suppress all other worldviews within the text in order to show the invulnerability of the political rhetoric …

The Supreme Court Chipping Away At Title Vii: Strengthening It Or Killing It?, Henry L. Chambers, Jr. Jan 2014

The Supreme Court Chipping Away At Title Vii: Strengthening It Or Killing It?, Henry L. Chambers, Jr.

Law Faculty Publications

Whether the Court's chipping away at Title VII is an attempt to make Title VII into a 21st century diamond, or an attempt to make it a 21st century pile of diamond dust, or merely an attempt to interpret Title VII consistent with its text is a matter of opinion. This Article explores how the Court is interpreting and reinterpreting Title VII and necessarily considers whether the Court's reinterpretation will likely reinvigorate or damage Title VII' s broad goal of workplace equality. This Article tentatively considers what may be next for Title VII. Part I briefly discusses Title VII's scope. …

The Problem Of Deterring Extraterritorial White-Collar Crime, Andrew B. Spalding Jan 2014

The Problem Of Deterring Extraterritorial White-Collar Crime, Andrew B. Spalding

Law Faculty Publications

Recent reports of egregious labor practices in China and Bangladesh have called public attention to the potential harms of foreign direct investment (FDI) in developing countries. The best, or at least most obvious, tool for reducing destructive overseas business practices would seem to be the extraterritorial application of white-collar criminal law. The "holy grail" of contemporary criminal law is deterrence, and the deterrence literature is largely shaped by the paradigm of law and economics. Prominent within that literature is Polinsky and Shavell's "enforcement authority," which seeks to maximize social utility through the efficient deterrence of crime.a Guided by the principles …

One-Step Production Of Long-Chain Hydrocarbons From Waste-Biomass-Derived Chemicals Using Bi-Functional Heterogeneous Catalysts, Cun Wen, Elizabeth A. Barrow, Jason R. Hattrick-Simpers, Jochen A. Lauterbach

Faculty Publications

n this study, we demonstrate the production of long-chain hydrocarbons (C8+) from 2-methylfuran (2MF) and butanal in a single step reactive process by utilizing a bi-functional catalyst with both acid and metallic sites. Our approach utilizes a solid acid for the hydroalkylation function and as a support as well as a transition metal as hydrodeoxygenation catalyst. A series of solid acids was screened, among which MCM-41 demonstrated the best combination of activity and stability. Platinum nanoparticles were then incorporated into the MCM-41. The Pt/MCM-41 catalyst showed 96% yield for C8+ hydrocarbons and the catalytic performance was stable …

Improving Methods For The Successful Establishment Of Switchgrass, Whitney Marie Monin Jan 2014

Improving Methods For The Successful Establishment Of Switchgrass, Whitney Marie Monin

Theses and Dissertations--Plant and Soil Sciences

Our research investigated whether priming switchgrass seeds with water or ethephon would increase stand establishment in the field. ‘Alamo’ seed germinated faster and grew taller than ‘Cave-in-Rock.Seeds primed for six days in water or for one day in ethephon 10 mM had the greatest seedling densities. In growth chamber environments seed priming were tested to hasten germination velocity. Seeds primed for two, four or six days in water germinated faster than unprimed seeds. Ethephon treatments reduced overall germination and germination velocity. Accent and Accent Q herbicides containing nicosulfuron are used to control weeds. To test ‘Alamo’ sensitivity to these herbicides, …

The Influence Of Tall Fescue Cultivar And Endophyte Status On Root Exudate Chemistry And Rhizosphere Processes, Jingqi Guo Jan 2014

The Influence Of Tall Fescue Cultivar And Endophyte Status On Root Exudate Chemistry And Rhizosphere Processes, Jingqi Guo

Theses and Dissertations--Plant and Soil Sciences

Tall fescue (Lolium arundinaceum (Schreb.) Darbysh.) is a cool-season perennial grass used in pastures throughout the Southeastern United States. The grass can harbor a fungal endophyte (Epichloë coenophiala) thought to provide the plant with enhanced resistance to biotic and abiotic stress. However, the alkaloids produced by the common variety of the endophyte cause severe animal health issues resulting in a considerable amount of research focused on eliminating the toxic class of alkaloids while retaining the positive abiotic and biotic stress tolerance attributes of the other alkaloids. In doing so, very little attention has been paid to the …

Evaluation Of Correlation Between Within-Barn Curing Environment And Tsna Accumulation In Dark Air-Cured Tobacco, Mitchell Dale Richmond Jan 2014

Evaluation Of Correlation Between Within-Barn Curing Environment And Tsna Accumulation In Dark Air-Cured Tobacco, Mitchell Dale Richmond

Theses and Dissertations--Plant and Soil Sciences

Significant variability in cured leaf tobacco-specific nitrosamine (TSNA) content is commonly observed when sampling within dark air-curing barns. This variability may be due to inconsistency in the curing environment within different areas of the barn. A study was initiated in 2012 through support from a CORESTA Study Grant to evaluate if leaf TSNA content is related to microenvironmental conditions in the barn. Seed screened for low conversion of nicotine to nornicotine (sc) and high converter (HC) selections of TR Madole dark tobacco were cured in barns near Princeton and Lexington, Kentucky in 2012 and 2013. Temperature and relative humidity were …

Mandatory Ultrasound Statutes And The First Amendment, Shifting The Constitutional Perspective, Cheri D. Smith Jan 2014

Mandatory Ultrasound Statutes And The First Amendment, Shifting The Constitutional Perspective, Cheri D. Smith

Cardozo Journal of Equal Rights & Social Justice

The jurisprudence of abortion law is replete with instances in which the concerns of the woman seeking the procedure have taken a back seat. The newest battleground in abortion regulation involves mandatory ultrasound statutes touted as informed consent regulations. The analysis of courts confronting these statutes has turned on whether the mandatory disclosures violate the physician's First Amendment right to be free from compelled speech. The particular breed of statute at issue in this paper requires a physician not only to perform an ultrasound, but also to make the images visible to the woman, to make audible the heartbeat, and …

(I Can't Get No) Satisfaction: Using Restorative Justice To Satisfy Victims' Rights, Jessica M. Marshall

Cardozo Journal of Conflict Resolution

The responsibility of sentencing defendants is the most difficult task within the criminal justice system. As the Honorable Jed S. Rakoff noted above, a sentencing judge is faced with the role of taking a guilty defendant and determining what punishment her crime warrants. Incarceration? Probation? Time served? Each judge evaluates the specific offense's characteristics, such as the number of victims, amount of loss, and violence of the offense, against the specific offender's characteristics, such as family history, age, and military service. As part of this evaluation, the defendant, the Government, the Probation Office in the form of a Presentence Report, …

Kill Switches, Forum Doctrine, And The First Amendment's Digital Future, Enrique Armijo Jan 2014

Kill Switches, Forum Doctrine, And The First Amendment's Digital Future, Enrique Armijo

Cardozo Arts & Entertainment Law Journal

Governments play a growing role in providing access to digital speech spaces. This development has important consequences for free expression. Communication's migration from physical public spaces to virtual ones has increased the State's capacity for ex ante interference with speech, from targeted blocking of users, websites, and applications on its communications networks to shutting off access to those networks altogether. Contrary to the conclusions of most Speech Clause scholars, the First Amendment's public forum doctrine is ill equipped to solve these problems, in part because the doctrine under-protects speech that is not expressed in shared physical space. Accordingly, this Article …
