A variety of new chiral one-carbon-bridged metallocene derivatives of titanium and zirconium have been prepared. Addition of the anions of cyclopentadiene, indene and fluorene to 6-t-butylfulvene and...
View ArticleCalcium and its role in mammalian egg activation
In Chapter 1 we characterized the frequency, amplitude and duration of (Ca$\sp{2+}\rbrack\sb{\rm i}$ rises in fertilized rabbit eggs loaded with fura-2 dextran. Their amplitude decreased and duration...
View ArticleElastomers based on polyesters produced by the bacterium Pseudomonas oleovorans
This dissertation has explored the structure property relationships of as extracted and chemically modified polyesters produced by the bacteria Pseudomonas oleovorans. The as extracted polymers are...
View ArticleAn engineered ribozyme targeting inhibin alpha subunit mRNA
Ribozymes are small RNA molecules that cleave specific RNA molecules enzymatically. Ribozymes can be designed to target specific RNA molecules, thereby modulating gene expression. A hammerhead...

A panel of monoclonal antibodies (MAbs) was generated against bovine oviduct cell surface antigens. Male mice were immunized with intact oviduct cells which had been collected by collagenase...
View ArticleCharacterization of insertion mutations in Bacillus anthracis capsule...
Transposon-mediated insertional mutagenesis was used for the isolation of auxotrophic mutants in plasmid-free derivatives of B. anthracis. A number of auxotrophic mutants were isolated and confirmed...

The goal of this research has been to enhance sample decomposition techniques through the coupling of flow technology with current sample digestion methodology in order to approach the characteristics...
View ArticleTensile-strained multiple quantum well electroabsorption modulators
A new effect leading to enhanced electroabsorption in quantum wells under biaxial tension is investigated through theoretical models and spectroscopic experiments. This effect is the electric...
View ArticleMicro-structural investigation of model polytetrahydrofuran networks
Model networks of polytetrahydrofuran (PTHF) were prepared by end-linking reaction with the known functionality of cross-links, and the specific number of network chains of known molecular weight...

This project focuses on the cultural fault lines that converged in the years between 1890 and 1920 to create a dynamic sense of folk regional identity among the people of western Massachusetts'...
View ArticleExcellence v. effectiveness: An exploration of MacIntyre's critique of business
Alasdair MacIntyre (1984) asserts that the ethical systems of the Enlightenment (formalism and utilitarianism) have failed to provide a meaningful definition of "good." Lacking such a definition,...
View ArticlePlanning referential expressions in speech production
Translating thoughts into sentences involves planning at several levels of representation (e.g., conceptual, syntactic, phonological). An adequate theory of speech production must specify the...
View ArticleA new accelerating technique for ray tracing complex scenes
Ray tracing has proven itself to be a highly effective method for producing photo-realistic images of three-dimensional scenes. The basic problem with ray tracing is the enormous amount of computation...
View ArticleThree essays on dynamic market-signaling equilibrium
Information (or knowledge) is an essential aspect of any exchange and any economy; yet, a mutually acceptable definition of information (or knowledge) does not exist among economists. Even a modest...
View ArticleSome results on source coding, vector quantization and progressive image...
In this dissertation, we investigate three problems in data compression, namely, source coding, vector quantization, and progressive image transmission. In source coding, we find the optimal...

This study focuses on the effect agency employees believe their values, attitudes, and perceptions of supervision have on the generalist students' field work education. A self-reporting three-part...
View ArticleReinstatement of causal information in reading
Four different tasks were used to investigate if readers reinstate information which is no longer in focus when it is needed to resolve a break in causal coherence. In five experiments an inference...
