Evaluation of virulence in wild type and pyrimidine auxotrophs of Pseudomonas aeruginosa using the eukaryotic model system Caenorhabditis elegans.

Description: The human opportunistic pathogen, Pseudomonas aeruginosa PAO1, has been shown to kill the nematode Caenorhabditis elegans. C. elegans has been a valuable model for the study of bacterial pathogenesis, and has reinforced the notion that common virulence and host defense mechanisms exist. Recently, the pyrimidine pathway was shown to regulate virulence levels. Therefore, mutations in the pyrimidine pathway of PAO1 showed decrease virulence in the nematode. When starving the nematode, bacterial… more

Hopfield Networks as an Error Correcting Technique for Speech Recognition

Description: I experimented with Hopfield networks in the context of a voice-based, query-answering system. Hopfield networks are used to store and retrieve patterns. I used this technique to store queries represented as natural language sentences and I evaluated the accuracy of the technique for error correction in a spoken question-answering dialog between a computer and a user. I show that the use of an auto-associative Hopfield network helps make the speech recognition system more fault tolerant. I also… more

Modeling wild type and mutant glutathione synthetase.

Description: Glutathione syntethase (GS) is an enzyme that belongs to the ATP-grasp superfamily and catalyzes the second step in the biosynthesis of glutathione. GS has been purified and sequenced from a variety of biological sources; still, its exact mechanism is not fully understood. Four highly conserved residues were identified in the binding site of human GS. Additionally, the G-loop residues that close the active site during catalysis were found to be conserved. Since these residues are important for … more

Functional analysis and elimination of SIB in an olive baboon (Papio hamadryas anubis).

Description: Self injurious behavior (SIB), such as self-biting and head-banging, has been reported to occur in approximately 10% of captive, individually housed primates (Novak, Kinsely, Jorgensen, and Hazen, 1998). Accounts of the causes of SIB range from environmental to physiological. However, to date, no researchers have investigated the possible influence of social consequences, delivered by handlers and keepers, in the maintenance of SIB. There is only one research report showing that self-injury can… more

The Destruction of a Society: A Qualitative Examination of the Use of Rape as a Military Tool

Description: This thesis explores the conditions under which mass rapes are more likely to be incorporated into the strategy of military or paramilitary groups during periods of conflict. I examine three societies, Rwanda , the former Yugoslavia , and Cambodia in a comparative analysis. To determine what characteristics make societies more likely to engage in rape as a military tool, I look at the status of women in the society, the religious cultures, the degree of female integration into the milit… more

Past tense marking in Chinese-English interlanguage.

Description: This data study concentrates on the past tense marking in the interlanguage (IL) of Chinese speakers of English. Following the assumptions of Hawkins & Lizska, (2003), it is assumed that unlike native speakers of English, Chinese speakers of English have a higher level of optionality within the past tense marking of their grammars. It is claimed that the primary reason for this occurrence is the lack of the functional feature T(ense) [+/-past] in Mandarin Chinese. If a particular functional fea… more

Voci Lontani for flute, trumpet, percussion, piano, and string quartet: Critical essay and score.

Description: This project consists of an original composition, Voci Lontani, and a critical essay about the composition. In this piece, the idea of musical simultaneity is explored. Therefore, the piece focuses on the idea of contrast: between measured rhythms and indeterminate rhythms, between tonality and atonality, and between musics in separate tempos. In order to explore the significance of musical simultaneity, four important compositional concepts-the simultaneous juxtaposition of different musics, … more

The Role of Violence in Hunt County, Texas, during Reconstruction

Description: The post Civil War period known as Reconstruction remains a topic of interest for historians. Having avoided the experience of invasion by Northern troops during the Civil War, the people living in the interior of the state of Texas accepted Confederate defeat at first. However, with the instituting of Northern efforts at Reconstruction, such as the installation of Republican interim government officials, the arrival of Freedmen's Bureau agents, and in some parts the stationing of federal troop… more

Asserting Identity in Wagner's Shadow: The Case of Engelbert Humperdinck's Königskinder (1897)

Description: Engelbert Humperdinck (1854-1921), who was considered a Wagnerian due to to his past work in Bayreuth and the Wagnerian traits of his Hänsel und Gretel, seems to have believed that to define himself as a composer, he had to engage somehow with that designation, whether through orthodox Wagner imitation or an assertion of his independence from Wagner's musical legacy. The latter kind of engagement can be seen in Humperdinck's Königskinder (1897), in which he developed a new kind of declamatory … more

Ethics Naturally: An Environmental Ethic Based on Naturalness

Description: In this thesis I attempt to base an environmental ethic on a quality called naturalness. I examine it in terms of quantification, namely, as to whether it can quantified? I then apply the concept to specific areas such as restoration and conservation to create an environmental ethic and to show how such an ethic would be beneficial in general, and especially to policy issues concerning the environment. The thesis consists of three chapters: (1) the definition of nature and natural by way of a h… more

An NMR Study of Trimethylsilylmethyllithium Aggregates and Mixed Trimethylsilylmethyllithium/Lithium trimethylsilylmethoxide Aggregates

Description: An NMR spectroscopy study of trimethylsilylmethyllilthium, TMSM-Li, indicates that TMSM-Li exists as two different aggregates in cyclopentane solution. Using previously reported colligative properties of TMSM-Li in different solutions in connection with new 13C and 6Li NMR data collected in this study, aggregation states were assigned as octamer and hexamer. Low temperature 13C and 6Li NMR peak intensities indicated an equilibrium exists between the two aggregates that shifts toward the octam… more
