Optimization Of Parameters And Study Of Kinetics In Lactulose Production By Lactose Isomerization Using Strong Basic Anion Exchange Resin, Arvind Nanduri

Masters Theses

"In this work, an experimental design was employed to investigate the effects of different operating conditions on the isomerization of lactose to lactulose by using strong basic anion exchange resin (AMBERLITE-IRA 402). Temperature, resin/lactose mass ratio and pH were considered to be the three factors affecting the conversion of lactose. Box-Behnken design was then used to optimize the operating conditions for maximum response and also to study the various interaction and main effects of the factors. The analysis of variance (ANOVA) of the experimental data showed a high correlation coefficient R² (0.99) and a low root mean square error (2.84) …

Comparing The Chelating Abilities Of N-Acetylcysteine And N-Acetylcysteine Amide In Vitro For Lead Poisoning Treatment, Weiqing Chen

Masters Theses

"Lead poisoning is a perennial and serious health problem around the world. The daily widespread use of lead has dramatically increased the degree and longevity of its exposure to humans, exacerbating the task of lead poisoning treatment. Lead exerts adverse effects on cardiovascular, central nervous, renal, gastrointestinal, and reproductive systems. The common treatment for lead poisoning is chelation therapy. Chelators were proposed to treat lead poisoning a very long time ago. However, chelators have severe side effects that could cause more problems, in addition to lead poisoning. Therefore, another group of drugs has been suggested --- antioxidants. This type of …

Cretaceous/Paleogene Boundary Biostratigraphy And Palynofacies Of The Alo-1 Well, Southeastern Nigeria, Janet Diane Raymer

Masters Theses

"The Cretaceous/Paleogene boundary (K/Pg) has been studied in great detail because of the fascination most people have with the extinction of the dinosaurs. The response of the vegetation to this extinction event has been studied in detail in mid to high latitudes, but little is known about what happened in the tropics. Sixty-seven samples from the Nsukka and Imo formations in the Alo-1 well in the Anambra Basin, southeastern Nigeria have been studied for their palynological contents. The aims of the study was to use spores, pollen and dispersed organic matter components to interpret biostratigraphy, and evaluate depositional conditions across …

A Positional Tagset For Russian, Jirka Hana, Anna Feldman

Department of Linguistics Faculty Scholarship and Creative Works

Fusional languages have rich inflection. As a consequence, tagsets capturing their morphological features are necessarily large. A natural way to make a tagset manageable is to use a structured system. In this paper, we present a positional tagset for describing morphological properties of Russian. The tagset was inspired by the Czech positional system (Hajič, 2004). We have used preliminary versions of this tagset in our previous work (e.g., Hana et al. (2004, 2006); Feldman (2006); Feldman and Hana (2010)). Here, we both systematize and extend these preliminary versions (by adding information about animacy, aspect and reflexivity); give a more detailed …

Emi Suppression Of Dc-Dc Synchronous Buck Converters By Layout Optimizations And Emi Prediction Using Non-Linear And Spice Circuit Co-Simulation, Ankit Bhargava

Masters Theses

"The oscillation on the phase voltage is due to the resonant structure formed by a parasitic loop (consisting of two FETs and the input decoupling capacitors) inductance and the output capacitance of the low side FET. Therefore, it is important to minimize this parasitic loop inductance. A simulation guideline is developed on full-wave modeling and simulation of buck converter layouts to estimate the parasitic loop inductances. Furthermore, this method is taken one step further to estimate the far-field radiation from the loop. These simulations were verified on six PCB variants of the buck converter and were compared with measurements in …

Developing A Model For Evaluating Software Tools In Education, Vedant Jain

Masters Theses

"This thesis proposes a research model to evaluate computer-mediated learning technology, user acceptance of the technology, and the effect of the technology on learning outcomes. This thesis also introduces two innovative research techniques for such evaluations, that is, eye-tracking and the think aloud protocol. Think aloud protocol allows us to understand a user's state of mind while he/she is interacting with the system. Eye-tracking provides additional insights into a user's cognitive state while using the system and can help triangulate the results. We demonstrated the application of the research model and research techniques in evaluating visualization software designed in a …

Embedded Optimal Control Of Mobile Robot Formations Using Neural Networks, Bryan M. Brenner

Masters Theses

"This work first presents the development of a nearly-optimal control scheme and then evaluates the effectiveness of this nearly-optimal control scheme by comparing it to a non optimal controller in Paper I. It is shown that the proposed nearly-optimal scheme is a significant improvement over the non optimal one in both simulation and hardware tests. The test was carried out on a differentially driven robotic vehicle in both obstacle free and obstacle ridden environments. On the other hand, the controller introduced for the obstacle avoidance in Paper II will also function in the absence of obstacles so that no switching …

China And Brazil: Potential Allies Or Just Brics In The Wall?, Anthony Petros Spanakos

Department of Political Science and Law Faculty Scholarship and Creative Works

Brazil is an increasingly important actor in global governance and for China specifically. Sino-Brazilian relations have deepened considerably but they remain concentrated in areas of trade and investment. There is also considerable overlap in interests between the two countries in other areas, such as diplomatic and political relations. At the same time, China must manage carefully important differences that exist over the enlargement of the UN and the potential challenge to the Brazilian industry.

Liver Injury In Acute Fatty Liver Of Pregnancy: Possible Link To Placental Mitochondrial Dysfunction And Oxidative Stress, Sathish Kumar Natarajan, Kavitha R. Thangaraj, C. E. Eapen, Anup Ramachandran, Ashis Mukhopadhya, Mathews Mathai, Lakshmi Seshadri, Abraham Peedikayil, Banumathi Ramakrishna, Kunnissery A. Balasubramanian

Department of Nutrition and Health Sciences: Faculty Publications

Acute fatty liver of pregnancy (AFLP) is a rare disorder which is fatal if not recognized and treated early. Delivery of the feto-placental unit results in dramatic improvement in maternal liver function, suggesting a role for the placenta. However, the mechanisms by which defects in the fetus or placenta lead to maternal liver damage are not well understood and form the focus of this study. Placenta and serum were obtained at delivery from patients with AFLP, and placental mitochondria and peroxisomes were isolated. Placental mitochondrial function, oxidative stress, and fatty acid composition as well asserumantioxidants, oxidativeandnitrosative stress markers,andfatty acid analysis …

Identification And Characterization Of Oxalate Oxidoreductase, A Novel Thiamine Pyrophosphate-Dependent 2-Oxoacid Oxidoreductase That Enables Anaerobic Growth On Oxalate, Elizabeth Pierce, Donald F. Becker, Stephen W. Ragsdale

Department of Biochemistry: Faculty Publications

Moorella thermoacetica is an anaerobic acetogen, a class of bacteria that is found in the soil, the animal gastrointestinal tract, and the rumen. This organism engages the Wood-Ljungdahl pathway of anaerobic CO₂ fixation for heterotrophic or autotrophic growth. This paper describes a novel enzyme, oxalate oxidoreductase (OOR), that enables M. thermoacetica to grow on oxalate, which is produced in soil and is a common component of kidney stones. Exposure to oxalate leads to the induction of three proteins that are subunits of OOR, which oxidizes oxalate coupled to the production of two electrons and CO₂ or bicarbonate. Like …

An Evaluation Of Three Statistical Methods Used To Model Resource Selection, David M. Baasch, Andrew J. Tyre, Joshua J. Millspaugh, Scott E. Hygnstrom, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

The performance of statistical methods for modeling resource selection by animals is difficult to evaluate with field data because true selection patterns are unknown. Simulated data based on a known probability distribution, though, can be used to evaluate statistical methods. Models should estimate true selection patterns if they are to be useful in analyzing and interpreting field data. We used simulation techniques to evaluate the effectiveness of three statistical methods used in modeling resource selection. We generated 25 use locations per animal and included 10, 20, 40, or 80 animals in samples of use locations. To simulate species of different …

Antibodies To Influenza And West Nile Viruses In Horses In Mexico, M. A. Loroño-Pino, J. A. Farfan-Ale, J. E. Garcia-Rejon, M. Lin, E. Rosado-Paredes, F. I. Puerto, A. Bates, J. J. Root, A. B. Franklin, H. J. Sullivan, B. J. Blitvich

INFLUENZA A virus (IAV) (family Orthomyxoviridae) is a highly infectious respiratory pathogen of birds and mammals, including human beings and horses (Palese and Shaw 2007). The virus is classified into different subtypes based on the antigenic properties of the haemagglutinin (HA) and neuraminidase (NA) proteins. Sixteen HA subtypes (H1 to H16) and nine NA subtypes (N1 to N9) have been identified (Fouchier and others 2005). Two subtypes, H3N8 and H7N7, have been isolated from horses. The H7N7 subtype was first isolated from a horse in Czechoslovakia in 1956 (Prague/56) (Sovinova and others 1958), and the H3N8 subtype was first isolated …

Foot-And-Mouth Disease In Feral Swine: Susceptibility And Transmission, F. Mohamed, S. Swafford, H. Petrowski, A. Bracht, B. S. Schmit, A. Fabian, J. M. Pacheco, E. Hartwig, M. Berninger, C. Carrillo, G. Mayr, K. Moran, D. Kavanaugh, H. Leibrecht, W. White, S. Metwally

United States Department of Agriculture Wildlife Services: Staff Publications

Experimental studies of foot-and-mouth disease (FMD) in feral swine are limited, and data for clinical manifestations and disease transmissibility are lacking. In this report, feral and domestic swine were experimentally infected with FMDV (A24-Cruzeiro), and susceptibility and virus transmission were studied. Feral swine were proved to be highly susceptible to A-24 Cruzeiro FMD virus by intradermal inoculation and by contact with infected domestic and feral swine. Typical clinical signs in feral swine included transient fever, lameness and vesicular lesions in the coronary bands, heel bulbs, tip of the tongue and snout. Domestic swine exhibited clinical signs of the disease within …

Biological, Technical, And Social Aspects Of Applying Electrified Fladry For Livestock Protection From Wolves (Canis Lupus), N. J. Lance, S. W. Breck, C. Sime, P. Callahan, J. A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

Context. Wolf predation on livestock can cause economic hardship for livestock producers as well as reduce tolerance for wolves. Lethal control of wolves is often controversial; thus, development of effective non-lethal methods for reducing wolf–livestock conflict is important. Electrified fladry is a new tool that is similar to fladry (i.e. a barrier system that scares wolves), but electrified fladry also incorporates an electric shock designed to decrease the potential for wolves to habituate to the barriers.

Aim. Evaluation of electrified fladry requires understanding of its effectiveness relative to fladry and the costs and benefits of applying it in …

Comparative Toxicity Of Diphacinone To Northern Bobwhite (Colinus Virginianus) And American Kestrels (Falco Sparverius), Barnett A. Rattner, Katherine E. Horak, Sarah E. Warner, Daniel D. Day, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

The acute oral toxicity of the anticoagulant rodenticide diphacinone was found to be about 20 times greater to American kestrels (LD₅₀=97 mg/kg) than to northern bobwhite (LD₅₀=2,014 mg/kg). Several precise and sensitive clotting assays (prothrombin time, Russell’s Viper venom time, thrombin clotting time) were adapted for use in these species, and this combination of assays is recommended to detect effects of diphacinone and other rodenticides on coagulation. Oral administration of diphacinone over a range of doses (sublethal to the extrapolated LD₁₅) prolonged prothrombin time and Russell’s Viper venom time within 24 to 48 hrs …

The Use Of Liver Microsome In-Vitro Methods To Study Toxicant Metabolism And Predict Species Efficacy, Katherine E. Horak, Chad R. Wermager, Thomas M. Primus

United States Department of Agriculture Wildlife Services: Staff Publications

Liver microsomes are used extensively in human pharmaceutical development to study the metabolism of compounds of interest; however, they are rarely part of the development of toxicants for the control of wildlife. Liver microsome samples from wildlife of interest would likely be harvested in the field without access to laboratory perfusion equipment. Therefore, the metabolic activity of microsomes from perfused and non-perfused livers was compared. There was no significant difference in diphacinone metabolism by liver microsomes from both perfused and non-perfused Wistar rat livers, although chlorophacinone metabolism was significantly different. There are often significant differences in metabolism between species that …

Wildlife Conservation Sunflower Plots And Croplands As Fall Habitat For Migratory Birds, Heath M. Hagy, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Agricultural fields are often overlooked as post-breeding and migratory bird habitat, even though many species use row-crop fields in the northern Great Plains. We monitored bird use, crop and non-crop vegetation characteristics and abundance, and land use around (≤2.4 km) 35 8-ha Wildlife Conservation Sunflower Plots (WCSP) and one commercial sunflower and non-sunflower row-crop field, paired with each WCSP, in fall 2004 and 2005. We excluded four species of blackbirds from our analysis that commonly form large foraging flocks and ubiquitously use agricultural fields. A diverse community of migratory birds used WCSP and commercial sunflower compared to other non-sunflower crops …

Evolving Analyses Of The Shoshone River Skunk Rabies Epizootic In Wyoming, Craig A. Ramey, Kenneth H. Mills, Justin W. Fischer

United States Department of Agriculture Wildlife Services: Staff Publications

A rabies epizootic occurred in striped skunks from 1988-1993 in a previously rabies-free area of northwestern Wyoming. USDA APHIS Wildlife Services (WS) cooperated with state and local officials by providing a rabies monitoring and depopulation program starting in 1990. Wyoming WS asked for assistance in 1991 from the National Wildlife Research Center (NWRC) to analyze the epizootic’s movements. The goal was to address the public’s concerns about their health and safety and that of their domestic animals and livestock. All rabid skunks were diagnosed by the Wyoming State Veterinary Laboratory (WSVL) using standardized fluorescent antibody testing of brain tissues. The …

American Bullfrogs As Invasive Species: A Review Of The Introduction, Subsequent Problems, Management Options, And Future Directions, Nathan P. Snow, Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Native to the eastern United States, American bullfrogs have been introduced throughout the western U.S. and to several other countries and islands around the world. Bullfrogs are well adapted for many of the permanent water sources that occur within the U.S., and once introduced, they typically become dominant. Because of their large size and voracious appetite, bullfrogs outcompete and prey upon many indigenous species. They are hypothesized to be cause significant negative impacts, which may contribute to the endangerment and extinction of some sensitive species. There are few, if any, effective and efficient control methods to manage invasive bullfrogs. Current …

Enzymatic Digestion Of Chronic Wasting Disease Prions Bound To Soil, Samuel Saunders, Jason C. Bartz, Kurt C. Vercauteren, Shannon L. Bartelt-Hunt

United States Department of Agriculture Wildlife Services: Staff Publications

Chronic wasting disease (CWD) and sheep scrapie can be transmitted via indirect environmental routes, and it is known that soil can serve as a reservoir of prion infectivity. Given the strong interaction between the prion protein (PrP) and soil, we hypothesized that binding to soil enhances prion resistance to enzymatic digestion, thereby facilitating prion longevity in the environment and providing protection from host degradation. We characterized the performance of a commercially available subtilisin enzyme, Prionzyme, to degrade soil-bound and unbound CWD and HY TME PrP as a function of pH, temperature, and treatment time. The subtilisin enzyme effectively degraded PrP …

I Put You There: User-Generated Content And Anticircumvention, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

This Article discusses recent rulemaking proceedings before the Copyright Office concerning the anticircumvention provisions of the Digital Millennium Copyright Act (DMCA). During these proceedings, non-institutionally affiliated artists organized to assert their interests in making fair use of existing works, adding new voices to the debate. A proposed exemption for noncommercial remix video is justified to address the in terrorem effect of anticircumvention law on fair use. Without an exemption, fair users are subjected to a digital literacy test combined with a digital poll tax, and this regime suppresses fair use. The experience of artists (vidders) confronting the law illustrates both …

Free Speech At What Cost?: Snyder V. Phelps And Speech-Based Tort Liability, Jeffrey Shulman

Georgetown Law Faculty Publications and Other Works

It is always a hard case when fundamental interests collide, but the Fourth Circuit’s decision in Snyder v. Phelps, 580 F.3d 206 (4th Cir. 2009), cert. granted, 130 S. Ct. 1737 (2010), tilts doctrine too far in the direction of free speech, upsetting the Supreme Court’s careful weighing of interests that takes into account both the need for robust political debate and the need to protect private individuals from personal abuse. Where speech is directed at a private individual, especially one unwilling to hear but unable to escape the speaker’s message, the elements of the emotional distress claim more than …

Unfair Competition And Uncommon Sense, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

This article discusses Mark McKenna’s Testing Modern Trademark Law’s Theory of Harm as an important step forward in challenging trademark expansionism, going back to basics and asking us to assess for truth value several propositions that now seem so self-evident to lawyers and judges as to not require any empirical support at all. Like McKenna, the author believes that if the law looked for the evidence behind present axioms of harm, it would not find much there. McKenna and the author share an interest in empirical evidence on marketing and a desire to bring its insights to trademark law. But …

Exporting U.S. Criminal Justice, Allegra M. Mcleod

Georgetown Law Faculty Publications and Other Works

This article explores how and why, in the Cold War’s wake, the U.S. government began to export U.S.-style criminal law and procedure models to developing and politically transitioning states. U.S. criminal law and development consultants now work in countries across the globe. This article reveals how U.S. initiatives have shaped state and non-state actors’ responses to a range of global challenges, even as this approach suffers from a deep democratic deficit. Further, this article argues that U.S. programs perpetuate U.S.-style legal institutional idolatry (which is often tied to systemic dysfunction both in the United States and abroad), and in so …
