Characterization of the Specificity of DNA Uptake and Transformation by Naturally Competent Acinetobacter Calcoaceticus

Description: Although cultures of A. calcoaceticus BD413 are naturally competent at all growth phases, genetic markers can only be successfully transformed by DNA from the genus Acinetobacter. Transformation frequencies of nearly 1.2% were obtained with pcaA mutants were incubated in liquid culture with wild-type DNA.

Brain-Reactive Antibodies: Molecular Specificity and Relationship to Biological Aging

Description: Brain-reactive antibodies (BRA) increase in frequency with age in several mammalian species and may be involved in the pathogenesis of age-related dementia. In this experiment, the molecular specificity of BRA in mouse sera was determined using an immunoblot assay, and the relationship of BRA to longevity was studied by comparing the rate of formation of specific BRAs in diet restricted C57BL/6NNia, B6D2F1/NNia, and DBA/2NNia, genotypes which differ markedly in life-span.

Particle size distribution and qualitative/quantitative analysis of trace metals in the combustion gas and fly ash of coal/refuse derived fuel

Description: This work includes two different areas of research. Both areas are related to the combustion of the binder-enhanced densified refuse derived fuel (bdRDF) with high sulfur coal and examining trace elements. The first area of this work involved studying the trace metals in the combustion gas of bdRDF/coal blend and the effect of the binder, CA(OH)2, on reducing the trace elements emissions. The second area of work involved studying the trace elements in the fly ash and the effect of the dRDF and … more

Picosecond degenerate four-wave mixing in semiconductors

Description: This study reports on a variety of experimental and theoretical studies conducted in ZnSe, CdTe, and in semiconductor-doped glasses. The transient picosecond degenerate four-wave mixing (DFWM) experiments performed in these II-VI direct-gap semiconductors are part of our efforts to understand the picosecond dynamics of the free-carriers generated via two and three-photon absorption.

Toxic chemical syndrome: body burden and immune parameters affected by environmental chemicals

Description: The purpose of the present study was to determine: (1) that dental office personnel would be exposed to more toxic chemicals in the workplace than the non-dental office controls; (2) that exposure should lead to a reduction in the efficiency of the immune system in the individuals in the dental office; and (3) the immunological deficit should manifest itself in psychological and/or physiological pathology as measured on the Profile of Mood States (POMS) and Bender Gestalt.

Ultrastructure of Azotobacter Vinelandii

Description: The purpose of this research was to reveal the morphological and cytological characteristics of Azotobacter vinelandii cells cultured in dialyzed soil medium. Culture samples taken at two, four, eight, sixteen and thirty-two days were prepared and examined with the electron microscope. Comparisons of the morphology of Azotobacter vinelandii grown in dialyzed soil medium with those grown in Burk's nitrogen-free, chemically-defined medium were done.

The emergence and development of Browning's auditor

Description: By presenting the auditor as a unifying principle that links Browning's earliest works to his dramatic monologues, this dissertation enhances the importance of the ever-ignored experimental works in developing the dramatic monologue technique. An exploration of the emergence and development of the auditor has an additional, but never ancillary, effect of proclaiming the originality and inventiveness of Browning's dramatic technique.

The Possibility of Branch Conformation in Azotobacter Vinelandii Chromosomal DNA Carrying Multiple Gene Copies and Its Folded State in the Cell

Description: Chromosomal DNA of A. vinelandii thought to carry multiple gene copies was examined in efforts to visualize its chromosomal structure using electron microscopy. The chromosomal DNA of A. vinelandii may have multiple circular genomic units carrying multiple copies of genes. Three possible branch construction schemes and their replication modes are postulated in this study.
