Methylglyoxal Effects on Cell Division of Scenedesmus quadricauda (Scenedesmaceae)

Cell division of ggeneflesmus quadricauda (Turp.) Breb. (Scenedesmaceae) is enhanced by methylglyoxal, a general inhibitor of cell division, at threshold concentration in conjunction with treatment timing related to growth stage of batch cultures. At 0.5 mM methylglyoxal concentration, cell division was significantly enhanced in algae treated in the logarithmic phase. Specific growth rates of methylglyoxal-treated cultures were rapidly increased at the beginning of logarithmic phase. Cultures i… more

Mark Twain: "Cradle Skeptic"

Critics discussing Mark Twain's early skepticism have, to date, confined their explorations to short studies (articles or book chapters), brief references in passing, or buried their insights in discussions on other topics. Other critics ignore Twain's atheistic statements and see his beliefs as theistic or deterministic. Others ascribe his attitudes in the "dark writings" to late life disappointments. This study demonstrates that Twain's later attitudes towards religion, determinism, social re… more

Consistency in Lattices

Let L be a lattice. For x ∈ L, we say x is a consistent join-irreducible if x V y is a join-irreducible of the lattice [y,1] for all y in L. We say L is consistent if every join-irreducible of L is consistent. In this dissertation, we study the notion of consistent elements in semimodular lattices.

Children's Cognitive and Moral Reasoning: Expressive Versus Receptive Cognitive Skills

Past research has shown that there are differences between children's ability to express verbally moral judgment or social cognitive principles (cognitive-expression) and their ability to understand and utilize these principles when making evaluations about others (cognitive-reception). This study investigated these differences.

Peace, Love, Unity, Respect, and Gender: Analyzing Gender at Raves

Doing, undoing, and redoing gender debates have established the omnirelevance and performativity of gender. Yet, little is known about the ways that individuals "do" gender in spaces that provide the opportunity for norms to be disrupted, such as subcultures. This study offers an empirical investigation into the performance of gender within the subculture known as EDM (electronic dance music) culture. Using 20 in-depth interviews that were conducted virtually, I analyze the way ravers experienc… more

Intelligence and the Uprising in East Germany 1953: An Example of Political Intelligence

In 1950, the leader of the German Democratic Republic (East Germany), Walter Ulbricht, began a policy of connecting foreign threats with domestic policy failures as if the two were the same, and as if he was not responsible for either. This absolved him of blame for those failures and allowed Ulbricht to define his internal enemies as agents of the western powers. He used the state's secret police force, known as the Stasi, to provide the information that supported his claims of western obstruc… more

Application of UV-Vis Spectroscopy to the Monitoring, Characterization and Analysis of Chemical Equilibria of Copper Etching Baths

The continuously increasing demand for innovation in the miniaturization of microelectronics has driven the need for ever more precise fabrication strategies for device packaging, especially for printed circuit boards (PCBs). Subtractive copper etching is a fundamental step in the fabrication process, requiring very precise control of etch rate and etch factor. Changes in the etching chemical equilibrium have significant effects on etching behavior, and CuCl2 / HCl etching baths are typically m… more

The Effects of Defensiveness and Social Desirability on the Reporting of Personality Traits

Psychological assessment relies on accurate and forthright reporting to determine valid clinical presentations. However, it has long been recognized that examinees may be motivated to present a "better picture" through Positive Impression Management (PIM). Within the PIM domain, two distinct motivations (i.e., defensiveness and social desirability) emerge that have not been clearly differentiated in empirical literature. This thesis addressed the research gap for detecting PIM distortion of per… more

Disease Tissue Imaging and Single Cell Analysis with Mass Spectrometry

Cells have been found to have an inherent heterogeneity that has led to an increase in the development of single-cell analysis methods to characterize the extent of heterogeneity that can be found in seemingly identical cells. With an understanding of normal cellular variability, the identification of disease induced cellular changes, known as biomarkers, may become more apparent and readily detectable. Biomarker discovery in single-cells is challenging and needs to focus on molecules that ar… more

Collective Security and Coalition: British Grand Strategy, 1783-1797

On 1 February 1793, the National Convention of Revolutionary France declared war on Great Britain and the Netherlands, expanding the list of France's enemies in the War of the First Coalition. Although British Prime Minister William Pitt the Younger had predicted fifteen years of peace one year earlier, the French declaration of war initiated nearly a quarter century of war between Britain and France with only a brief respite during the Peace of Amiens. Britain entered the war amid both a nad… more

Dynamic Screening via Intense Laser Radiation and Its Effects on Bulk and Surface Plasma Dispersion Relations

Recent experimentation with excitation of surface plasmons on a gold film in the Kretschmann configuration have shown what appears to be a superconductive effect. Researchers claimed to see the existence of electron pairing during scattering as well as magnetic field repulsion while twisting the polarization of the laser. In an attempt to explain this, they pointed to a combination of electron-electron scattering in external fields as well as dynamic screening via intense laser radiation. Th… more

Kinetic Study of the Reactions of Chlorine Atoms with Fluoromethane and Fluoromethane-d3 in the Gas Phase

The kinetics of the gas-phase reactions of chlorine atoms with fluoromethane (CH3F) and fluoromethane-d3(CD3F) were tested experimentally. The relative rate method was applied by using CH4 as the reference compound for fluoromethane (CH3F) and CH4 and CH3F as the reference compound for fluoromethane-d3(CD3F). The rate constants for H-abstraction from CH3F and D-abstraction from CD3F were measured at room temperature and a total pressure of 920 Torr using Ar as a diluent. The rate constants are … more

Food and the Master-Servant Relationship in Eighteenth and Nineteenth-Century Britain

This thesis serves to highlight the significance of food and diet in the servant problem narrative of eighteenth and nineteenth-century Britain and the role of food in master-servant relationships as a source of conflict. The study also shows how attitudes towards servant labor, wages, and perquisites resulted in food-related theft. Employers customarily provided regular meals, food, drink, or board wages and tea money to their domestic servants in addition to an annual salary, yet food and m… more
