A chemical study of the minerals from L-6 chondritic meteorites

Creator:: Curtis, David Ballantyne
Abstract:: Major and minor minerals have been separated from three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin), and Leedey). Olivine, hypersthene, diopside, feldspar, troilite, chromite, phosphate minerals, and metallic minerals were analyzed for major, minor and trace elements using instrumental neutron activation analysis and radiochemical neutron activation analysis techniques. Concentrations df the...

Engineering an Ex-Vivo System to Study Transport Phenomena in the Human Intervertebral Disc

Creator:: Shalash, Ward
Abstract:: Back pain is the leading cause of disability worldwide, entailing a significant socioeconomic impact. A primary source of back pain can be attributed to intervertebral disc (IVD) degeneration allowing nerve ingrowth, facet joint arthritis, disc bulging, and osteophyte formations that press on nearby nerve roots or the spinal cord. While...

Documenting Significant Life Experiences in Nature, Nature Relatedness, and Mind Maps: A Case Study of United Methodist Church Members

Creator:: Sams, Jennifer D.
Abstract:: This study investigates the environmental-based life experiences in nature, nature relatedness, and demographic variables reported by members of First United Methodist Church (FUMC) of Claremore, Oklahoma. Previous studies have noted a lack of nature connectedness in modern culture and society and that this disconnect may impact human interactions with nature....

How does a collaborative community affect diverse students' engagement with an open source software project : a pedagogical paradigm

Creator:: Morgan, Becka S.
Abstract:: Open Source Software (OSS) communities are homogenous and their lack of diversity is of concern to many within this field. This problem is becoming more pronounced as it is the practice of many technology companies to use OSS participation as a factor in the hiring process, disadvantaging those who are...

A double-stranded secondary structure for hyaluronic acid in aqueous-organic solvent as revealed by vacuum ultraviolet circular dichroism

Creator:: Staskus, Paul
Abstract:: The association of hyaluronic acid (HA) into a double stranded structure has been investigated by circular dichroism (CD) spectroscopy into the vacuum ultraviolet region. The CD of HA changes dramatically, monitoring a cooperative transition as the dielectric constant of an aqueous solution is reduced by adding organic solvents. This structural...

Porous polymer trapping for GC/MS analysis of volatile flavor compounds in corn

Creator:: Boyko, Alayne Linda
Abstract:: Flavor profiles of canned and frozen whole kernel sweet corn were obtained by entraining the volatile compounds on Porapak 0 traps and by subsequent analysis on temperature-programed, 500' by 0.03" ID capillary columns (SF-96 or Carbowax 20M). Identification was based on GC/MS data, retention indices (I[subscript E]'s) and retention times....

Assessing mechanisms of immunotoxicity for polycyclic aromatic hydrocarbons in rainbow trout (Oncorhynchus mykiss)

Creator:: Bravo, Claudia F.
Abstract:: During the past 30 years, numerous studies have focused on the toxicities of polycyclic aromatic hydrocarbons (PAH). Laboratory and field studies have helped elucidate the detrimental effects of these chemicals on growth, reproduction and immune response. Polycyclic aromatic hydrocarbons are in the priority list of chemicals to be studied by...

Semi-volatile organic compounds and developing organisms : accumulation in California mountain tadpoles in the field and fish embryo exposures in the laboratory

Creator:: Stanley, Kerri A.
Abstract:: The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...

Convergent margin magmatism in the central Andes and its near antipodes in western Indonesia : spatiotemporal and geochemical considerations

Creator:: Salisbury, Morgan J.
Abstract:: This dissertation combines volcanological research of three convergent continental margins. Chapters 1 and 5 are general introductions and conclusions, respectively. Chapter 2 examines the spatiotemporal development of the Altiplano-Puna volcanic complex in the Lípez region of southwest Bolivia, a locus of a major Neogene ignimbrite flare- up, yet the least...
