Application Of Reanalysis Techniques For Pattern Design Of Spot Welds, Young San Kim

Mechanical & Aerospace Engineering Theses & Dissertations

Extensive benchmarking on competitive cars has shown that the durability of vehicles, assembly-induced variations, and assembly cost are directly related to the quality and number of spot welds. On most luxury cars, approximately 4,500 to 5,000 spot welds are found. On less expensive cars, the range is from 3,500 to 4,500. These cars usually inherit more noise, rattles, squeaks, and other quality-related problems. These problems have motivated the search for a new capability to systematically place welds in the most critical areas, with a minimum number of welds for car bodies, while satisfying all performance requirements (e.g., stiffness, stress distribution, …

Mutations In Trans-Acting Factors Affecting Mrna Decapping In Saccharomyces Cereviciae, Lianna K. Etchberger, C. A. Stevens, A. Stevens, R. Parker

Biology Faculty Publications

The decay of several yeast mRNAs occurs by a mechanism in which deadenylation precedes decapping and subsequent 5'-to-3' exonucleolytic decay. In order to identify gene products required for this process of mRNA turnover, we screened a library of temperature-sensitive strains for mutants with altered mRNA degradation. We identified seven mutations in four genes that inhibited mRNA turnover. Two mutations were alleles of the XRN1 5'-to-3' exoribonuclease known to degrade mRNAs following decapping. One mutation defined a new gene, termed DCP1, which in subsequent work was demonstrated to encode a decapping enzyme or a necessary component of a decapping complex. The …

Numerical Chromosome Abnormalities In Sperm From Oligoasthenoteratozoospermic Patients And Fertile Males, Myung-Geol Pang

Theses and Dissertations in Biomedical Sciences

Artificial fertilization protocols have been developed which bypass natural barriers for reproduction. One aspect of infertility which has received little attention is the potential importance of aneuploidy in sperm. To more clearly understand the cytogenetic make-up of sperm from OAT patients, multi-probe, multi-color FISH was performed to determine aneuploidy.

The introduction of intracytoplasmic sperm injection (ICSI) has revolutionized protocols used in in vitro fertilization centers. The pregnancies resulting from ICSI suggest an increased frequency of sex chromosome aneuploidy in livebirths. Preliminary data by others' suggest that sperm tail swelling patterns following hypo-osmotic swelling (HOST) can be predictive of fertilizing ability. …

Fate Of Biological Control Introductions: Monitoring An Australian Fungal Pathogen Of Grasshoppers In North America, Michael J. Bidochka, Scott R. A. Walsh, Mark E. Ramos, Raymond J. St. Leger, Julie Cl Silver, Donald W. Roberts

Biology Faculty Publications

In North America there are two generally recognized pathotypes (pathotypes 1 and 2) of the fungus Entomophaga grylli which show host-preferential infection of grasshopper subfamilies. Pathotype 3, discovered in Austra- lia,hasabroadergrasshopperhostrangeandwasconsidered to be a good biocontrol agent. Between 1989 and 1991 patho- type3wasintroducedattwofieldsitesinNorthDakota.Since resting spores are morphologically indistinguishable among pathotypes, we used pathotype-specific DNA probes to con- firm pathotype identification in E. grylli-infected grasshop- pers collected at the release sites in 1992, 1993, and 1994. In 1992, up to 23% of E. grylli-infected grasshoppers of the subfamilies Melanoplinae, Oedipodinae, and Gomphocerinae were infected by pathotype 3,with no infections >1 km …

Formation And Structure Of C-8-Oxo/Aryl-Guanine Adducts In Dna., Wai-Ming Yau

Graduate Theses, Dissertations, and Problem Reports (ETD)

In biology and medicine, free radicals are now of intense interest because they have been shown to be involved in many different aspects of metabolism, ranging from oxygen consumption and autocatalysis to xenobiotic metabolism. Formation of free radicals in various systems may contribute to diseases and degenerative processes. Free radicals attack guanine in DNA to give 8-substituted guanine derivatives including C-8-oxo-2{dollar}\\sp\\prime{dollar}-deoxyguanosine (oG) and C-8-aryl guanine derivatives via hydroxy and aryl radicals, respectively. The work to be described herein resulted from studies of both adducts in relation to carcinogenesis and other pathogenesis. This dissertation is divided into five chapters. Chapter I …
