Release And Removal Of Microcystins From Microcystis During Disinfection Treatments, Jie Ding

Masters Theses

"The presence of algal toxins, or cyanotoxins, in surface water has been increasingly reported. These highly hazardous toxins are potential threat to both human health and animals by contaminating drinking water sources over the world. In this research project, inactivation of Microcystis aeruginosa cells and release and removal of intracellular microcystins during several oxidative and physical treatments was studied. The results of this study show that chlorine dioxide, sonication, low salinity and quick blending with tissuemiser caused immediate release of microcystin-LR to water after treatment. No significant increase of toxin level was observed after treatment with free chlorine, ozone, permanganate, …

A Systematic Approach To Project Portfolio Selection For Economic Development In Municipalities: A Case Study In Vienna, Missouri, Amanda Danielle Alpaugh

Masters Theses

"Economic development is essential for the survival of all municipalities in the United States. Economic growth, created through project implementation, brings new capital into municipalities by increasing the tax base. Smaller municipalities often struggle to implement projects that promote economic growth. These municipalities run into problems because they lack resources to hire an economic consultant and capabilities to independently complete the strategic planning process. This thesis describes an easy-to-use and easy-to-implement systematic ten-step approach to project portfolio selection for economic growth within smaller municipalities...The ten-step approach was employed in a case study performed in Vienna, Missouri. The case study involved …

Modeling And Measurement Of Thermal Residual Stresses And Isotope Effects On Thermo Physical Properties Of Zrb₂-Sic Ceramics, Michael P. Teague

Masters Theses

"Commercially available finite element modeling software (ABAQUS) was used to investigate the internal residual stresses that develop as a result of cooling from processing temperatures in ZrB₂-SiC ceramics. The size and shape of the SiC particles were varied to evaluate their effect on the residual stresses. Results were compared to experimental data and showed similar trends, where increasing SiC particle size increased tensile stress and also decreased strength. Models were used to analyze benefits of novel shaped SiC inclusions and also better understand the short comings of the composites. An attempt to validate the models using neutron diffraction to measure …

Role Of Microtubules In Budding Yeast Cytokinesis, Su Young Park

Masters Theses

"Cytokinesis is an important step to finish cell cycle events and separate into two daughter cells. This event is driven by actomyosin ring contraction. In budding yeast, the mitotic exit network (MEN) controls completion of ana/telophase by signaling events. Bub2 is a mitotic exit network regulator and binds to Tem1p which is an important component in MEN. Mad2 is a component of a separate spindle checkpoint. Mad2 dependent pathway prevents the metaphase to anaphase transition under spindle damage. Because yeast cells have cell walls, septum formation follows actin ring contraction. Here it was investigated how microtubule defects affect cytokinesis in …

Friction Stir Spot Welding Of Aluminum Alloys, Wei Yuan

Masters Theses

"Efforts to reduce vehicle weight and improve safety performance have resulted in increased application of light-weight aluminum alloys and a recent focus on the weldability of these alloys. Friction stir spot welding (FSSW) is a solid state welding technique (derivative from friction stir welding (FSW), which was developed as a novel method for joining aluminum alloys). During FSSW, the frictional heat generated at the tool-workpiece interface softens the surrounding material, and the rotating and moving pin causes material flow. The forging pressure and mixing of the plasticized material result in the formation of a solid bond region. The present work …

A Hybrid Sensor Network For Watershed Monitoring, John R. Koch

Masters Theses

"This thesis discusses the Hydrological Hybrid Communication Sensor Network (HHCSN), which is designed for in situ measurement of various hydrological properties of a watershed. HHCSN is comprised of a network of sensor strings, each of which connects up to 100 sensing nodes on a communication line as long as 100 m. Each node includes sensors that measure soil attributes of interest, as well as a microcontroller with basic communication and processing capabilities. A relay point at the surface compresses data from the nodes and wirelessly transmits it to a base station that serves as a gateway to the outside world. …

Friction Stir Channeling: An Innovative Technique For Heat Exchanger Manufacturing, Nagarajan Balasubramanian

Doctoral Dissertations

"Friction stir processing (FSP) is an emerging processing technique based on the principles of friction stir welding (FSW), which is a relatively new solid-state metal joining process developed by The Welding Institute, UK. Some of the unique features of FSW such as the low amount of heat generated, extensive plastic deformation and controlled flow of material is being exploited to develop new material modification and manufacturing processes. Friction stir channeling (FSC) is one such adaptation of FSP that can produce continuous and stable internal channels for application in heat exchanging equipment. Friction stir channeling produces these channels if the defect …

Synthesis And Evaluation Of Vegetable (Soybean) Oil Based Epoxy Resin For Beverage Can Coating And Enzymatic Synthesis And Characterization Of Tailored N&C End Protected Oligopeptides, Ying Gao

Doctoral Dissertations

"Research described in this dissertation covers two topics. Part-I is related to the development of a soybean oil based epoxy resin and its application in beverage can coatings. Interior surfaces of beverage can are invariably coated with polymer coating. The most commonly used coatings at present are derived from bisphenol A (BPA) based epoxy reins. However, due to perceived endocrine disrupting nature of BPA and consequential adverse effects on humans and wildlife concerns for the use of BPA based coatings and its leaching into beverages have been expressed. The research in the first part describes the synthesis and evaluation of …

Densification, Microstructure, And Mechanical Properties Of Zirconium Diboride Based Ultra-High Temperature Ceramics, Sumin Zhu

Doctoral Dissertations

"The first part of this dissertation was aimed at studying the densification of ZrB₂ ceramics by pressureless sintering techniques. Various processes have been applied to coat ZrB₂ powders with polymer precursors, which were used to produce C after charring. After sintering at 1900⁰C, relative density increased of ~70% for uncoated ZrB₂ to >99% for ZrB₂ coated with at least 1.0 wt% C. Thermodynamic analysis suggested that C reacted with and removed oxide impurities (ZrO₂ and B₂O₃) that were present on the ZrB₂ particle surfaces, which promoted densification by minimizing grain coarsening"--Abstract, page iv.

The Effect Of Free Chlorine And Monochloramine On Lead In Drinking Water And Epitaxial Electrodeposition Of Tin Sulfide, Sansanee Boonsalee

Doctoral Dissertations

"Electrochemical deposition is utilized in various electronic and photovoltaic applications and in the protective coating industries. This dissertation primarily addresses the environmental aspects of electrochemical deposition. In the first part of this study, Pb dissolution in drinking water was investigated in the presence of two disinfectants: free chlorine (in the form of HOCI/OCr) and monochloramine (NH₂Cl). In the second part of this study, epitaxial SnS nanodisks were electrodeposited onto a Au(100) substrate. Water utility systems use either free chlorine or monochloramine in their disinfection program. Whereas free chlorine reacts with natural organic matter in the water to produce halogenated organic …

Design And Evaluation Of A Virtual Reality Training System For New Underground Rockbolters, David Nutakor

Doctoral Dissertations

"The need for development of better training techniques for underground rock bolters is signified by the fact that a large number of experienced miners (Baby Boomers) will be retiring soon. This means that there will be very little interface time between the new miners and the experienced miners, which could have been used for training the new inexperienced miners. A new generation of workers (Nexters), who have grown up with computers and video games will replace the Baby Boomers, and the most efficient way to introduce them to the safety and health issues of the mining industry is to use …

Women In Science: Stories From The Margins, Laura Mathis Mulvanity

College of Graduate Studies: Theses & Dissertations

Women are significantly underrepresented in the hard sciences and engineering. While the number of women seeking degrees in these fields has increased in the last forty years, a substantial gap still exists between the sexes. The purpose of this dissertation is to examine one area of influence on career choice -- the curriculum. Women scientists are underrepresented in the school curriculum. This dissertation examines the discourse of curriculum and the role it has in the gendering of the field of science. The nature of the development of a curriculum lends itself to the practice of exclusion. The construction of curriculum …

Can Constitutionalism Be Leftist?, Louis Michael Seiman

Georgetown Law Faculty Publications and Other Works

In this essay, written for a symposium on the work of Mark Tushnet, I examine Tushnet’s effort to defend popular constitutionalism in his powerful and subtle book entitled ATaking the Constitution Away from the Courts,” I ask whether the book succeeds in reconciling constitutionalism with leftism. If there is anyone who could accomplish this task, it is Tushnet. He is without question our most thoughtful constitutional leftist. And yet, the book, at least taken at face value, fails to achieve its goal. To the extent that the book argues for constitutionalism, it abandons leftism, and to the extent it is …

Gone In Sixty Milliseconds: Trademark Law And Cognitive Science, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

Trademark dilution is a cause of action for interfering with the uniqueness of a trademark. For example, consumers would probably not think that "Kodak soap" was produced by the makers of Kodak cameras, but its presence in the market would diminish the uniqueness of the original Kodak mark. Trademark owners think dilution is harmful but have had difficulty explaining why. Many courts have therefore been reluctant to enforce dilution laws, even while legislatures have enacted more of them over the past half century. Courts and commentators have now begun to use psychological theories, drawing on associationist models of cognition, to …

Sight, Sound And Meaning: Teaching Intellectual Property With Audiovisual Materials, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

This article addresses the author's experience using audiovisual materials from the Georgetown Intellectual Property Teaching Resources database. She used audiovisual materials extensively in class to allow students to see the subject matter of the cases rather than just reading verbal descriptions and enable them to apply the principles they read about to new, concrete examples. Many students in IP courses have special interests in music, film, or the visual arts, and the database allows her--and other teachers--to present materials that engage them. She found that students are more willing to speak up in class when they can see or hear …

Does Doj's Privilege Waiver Policy Threaten The Rationales Underlying The Attorney-Client Privilege And Work Product Doctrine? A Preliminary "No", Julie R. O'Sullivan

Georgetown Law Faculty Publications and Other Works

According to white-collar defense practitioners, the demise of the corporate attorney-client privilege and work product doctrine is imminent. While a variety of assaults have been identified, by far the most oft-cited culprit is the U.S. Department of Justice (DOJ), whose prosecutors, it is charged, have routinely insisted that corporations waive these protections to secure cooperation credit and declination of criminal action against the corporate actor and/or consideration at sentencing. DOJ has, by and large, vigorously defended its policies in this regard. Congress now threatens to inject itself into the debate: legislation entitled the "Attorney-Client Privilege Protection Act" has been introduced …

A Rapid Method For Determination Of Alpha Hydroxy Acids In Seawater And Biological Fluids At Trace Levels, Ryan Lee Schwiderski

Masters Theses

"Alpha hydroxy acids (AHAs) - carboxylic acids with a hydroxyl substitution on the alpha carbon are an important class of molecules. Hydroxy Methyl Thiobutanoic Acid (HMTBA) is an α-hydroxy analog of essential amino acid methionine; it finds extensive use as a feed supplement for avian and bovine species. Efficacy of alpha hydroxy acid uptake is important for nutritional studies and such studies rely on accurate and precise methods for determination of these chemicals in biological samples. Several methods for AHAs determination have been reported, however, the methods are tedious, requiring multiple sample preparation steps. Experiments reported in this thesis were …

A Laboratory Study Of Struvite Precipitation For Phosphorus Removal From Concentrated Animal Feeding Operation Wastewater, Sushmita Dhakal

Masters Theses

"Struvite precipitation occurs spontaneously in many wastewater treatment facilities as a nuisance. However, struvite precipitation is now being studied as a method to concurrently treat high phosphorus wastewaters and generate a valuable product. Many factors influence the precipitation of struvite such as component -ion molar ratios, pH, aeration, solubility, solids and mixing energy. In the present work, struvite precipitation in the actual swine wastewater was studied by strategically controlling aeration, pH, and mixing"--Abstract, page iv.

Codes And Hypertext: The Intertextuality Of International And Comparative Law, Marylin J. Raisch

Georgetown Law Faculty Publications and Other Works

The field of information studies reveals gaps in the literature of international and comparative law as part of interdisciplinary and textual studies. To illustrate the kind of theoretical and text-based work that could be done, this essay provides an example of such a study. Religious law texts, civil law codes, treaties and constitutional texts may provide a means to reveal the nature of hypertext as the new format for commentary. Margins used to be used for commentary, and now this can be done with hypertext and links in footnotes. Scholarly communication in general is now intertextual, and texts derive value …
