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...

Measuring in situ biotransformation in BTEX-contaminated groundwater

Creator:: Alumbaugh, Robert E.
Abstract:: Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

Quantifying in situ β-glucosidase and phosphatase activity in groundwater

Creator:: Radakovich, Karen M
Abstract:: Enzymes play an important role in the environment, they breakdown natural-occurring and anthropogenic molecules so that they can be transported into cells and utilized. Enzyme assays are routinely used in soil science and oceanography to measure the activities of specific processes and to serve as general indicators of microbial activity....

The chemical composition of 61 individual Allende chondrules

Creator:: Warren, Richard Gregory
Abstract:: The abundances of 12 elements, Fe, A1, Na, Ni, Cr, Mn, Co, Ca, Sc, Ir, Sm and Eu have been determined by INAA in 61 individual chondrules (0.1-100 mg) separated from five Allende (C3) meteoritic fragments ( 25g). Ti and V have been determined in 18 of these chondrules, and...

Occurrence and distribution of perfluorinated surfactants in groundwater contaminated by fire-fighting activity

Creator:: Bartel, Cheryl Moody
Resource Type:: Dissertation
Full Text:: surfactant itself as well as a precursorto other fluorinated surfactants and pesticides (5). The

Fate and transport of the surfactant linear alkylbenzenesulfonate in a sewage-contaminated aquifer

Creator:: Krueger, Carolyn J.
Abstract:: Linear alkylbenzenesulfonate (LAS) is the most widely used anionic surfactant in commercial detergent formulations. The environmental fate of LAS is of interest because of its disposal to wastewater treatment facilities and subsequent occurrence as a micropollutant in surface waters and groundwater. While LAS fate in wastewater treatment systems and surface...

Variations in trace element abundances in small fragments from a single terrestrial basaltic flow : applications to 59 Apollo-17 mare basaltic fragments

Creator:: Rivera, Maria Rita Dacanay
Abstract:: Eleven hand specimen whole rock (WR) samples (25-200 g each) and 33 fragments (0.5-0.8 g each) from a single basaltic flow at Picture Gorge, Oregon were analyzed via instrumental neutron activation analysis (INAA) for 12 elements (Na, Fe, Cr, Sc, Co, La, Sm, Eu, Yb, Lu, Hf and Ta). Standard...

Chemical and statistical analyses of chondrules from the Mokoia (CV3) meteorite

Creator:: Schilk, Alan J.
Abstract:: Nearly 100 chondrules were extracted from -8.6g of the Mokoia (CV3) meteorite and have been analyzed by sequential instrumental neutron activation analysis (INAA). The resulting data were utilized in a comprehensive statistical characterization of these objects and, unlike similar investigations, virtually no loss of relevant data was incurred due to...

The synthesis of substituted 1, 8-naphthyridines by the Doebner reaction

Creator:: Samalapa, Prasit
Abstract:: The possibility of synthesizing 1, 8-naphthyridines by the Doebner reaction has appeared in many reports. The method involves the introduction of electron releasing groups in the 6-position of 2-amino pyridine to activate the C-3 position. Previously Lewis used 6-methyl-2-amino pyridine with benzaldehyde and pyruvic acid, in an attempt to prepare...
