L. C. Dunn (1893-1974) spent most of his scientific career conducting research in
developmental genetics as a member of the Zoology Department at Columbia
University in the City of New York. He had an accomplished scientific career
researching mutations in mice, which earned him respect from other geneticists and
scientists....
The growth of foster care, particularly kin foster care has greatly outpaced our knowledge. The purpose of this exploratory qualitative study was to develop a more informed understanding of foster family functioning from the perspective of foster parents. This study examined the experiences of 9 kin and 12 nonkin foster...
The critical contribution of this dissertation is to provide a better
understanding of the fundamental Chemical Bath Deposition (CBD) growth
kinetic and mechanism for the well known II-VI semiconductor CdS using the
newly developed continuous flow microreactor. This continuous flow microreactor
provides the temporal resolution to control the homogeneous reaction...
Human exposure to the carcinogenic polycyclic aromatic hydrocarbons (PAHs) benzo[a]pyrene (B[a]P) and dibenzo[a,l]pyrene (DB[a,l]P) is through environmental complex mixtures, such as urban dust particulate matter (UDPM) and diesel exhaust (DE), however the potency of these PAH within a mixture is not established. To determine the effect of these mixtures on...
Tetracycline (Tet)-resistant strains of Chlamydia suis were isolated from swine
farms in the Midwest. The isolation of the resistant strains was significant
because Tet is an antibiotic used to treat infections by veterinarians and
doctors. One of the tetracycline (Tet)-resistant strains, R19, was able to
survive in Tet up to...
Clostridium perfringens type A isolates, an anaerobic enterotoxigenic spore forming bacterium, are the third leading cause of food-borne disease in the United States. Factors that contribute to the virulence of C. perfringens include the ability of the bacterium to form heat resistant spores and to produce an enterotoxin (CPE). Although...
The fungus Cochliobolus victoriae causes Victoria blight of oats and Arabidopsis and is pathogenic due to its production of a compound called victorin, which induces programmed cell death in sensitive plants. Victorin sensitivity in Arabidopsis is conferred by the dominant gene LOCUS ORCHESTRATING VICTORIN EFFECTS1 (LOV1), which encodes a coiled-coil-nucleotide...
Overtly non-toxic doses of organochlorine (OC) insecticides perturb lipid homeostasis
in mice and rats. To increase understanding of how chlordecone (CD), an OC
insecticide, modulates cholesterol (CH) homeostasis, we determined the effect of CD
pretreatment on the tissue and hepatic subcellular distribution of exogenous [¹⁴C]CH. Corn oil alone or CD...
White mold, caused by Sclerotinia sclerotiorum (Lib.) De Bary, is a destructive yield-limiting disease of common bean (Phaseolus vulgaris L.). Genetic resistance to this pathogen is limited in common bean. Identification of high levels of partial physiological resistance in a genetically cross compatible species, Phaseolus coccineus, is advisable. The objectives...
The aim of this dissertation is to develop oxide semiconductors by radio-frequency
sputtering for thin-film transistor (TFT) applications. A variety of oxide semiconductors
are used as the TFT channel layer, including indium gallium oxide (IGO), zinc tin
oxide (ZTO), and indium gallium zinc oxide (IGZO). The variety of materials used...
