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...

Conformation and reactivity studies of some bicyclo(3.3.1) nonane derivatives

Creator:: Sturmer, David Michael
Abstract:: New syntheses for 2-bicyclo(3.3.1)nonanone and 7-bicyclo-(3.3.1)nonen-2-one were developed. The saturated ketone was prepared from phenol and acrylonitrile via a novel intramolecular S[subscript N]2 cyclization process. A Friedel-Crafts cyclization of 3-(3-cyclohexenyl)propanoyl chloride permitted synthesis of the unsaturated ketone from 4-cyclohexene carboxaldehyde. The formation of the bicyclo(3.3.1)nonane rather than a bicyclo(3.2.2)nonane skeleton...

Preparation and comparative solubility of poly-L-tyrosyl lysozyme and poly-O-methyl-L-tyrosyl lysozyme

Creator:: Venier, Lynn Corrine
Abstract:: In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited similar pH dependent solubilities, showing a minimum solubility at about pH 8. Their solubilities varied with temperature, having a positive enthalpy of solution. The effect of a...

Mass spectrometric analysis of bovine neurofilament proteins NF-L, NF-M, and NF-H : peptide mapping, phosphorylation and alkylation site identification

Creator:: Mixon, April E.
Abstract:: Neurofilament proteins are intermediate filaments found in the neuronal cytoskeleton. Phosphorylation of these proteins is considered important for the assembly and stability of the filaments. Accurate molecular weights have been difficult to measure, largely because the high degree of phosphorylation results in M[subscript r]'S that are significantly greater than dictated...

Preparation and properties of poly-L-tyrosyl acetamidinated ribonuclease

Creator:: Lynn, Jackson
Abstract:: Polypeptidyl derivatives of bovine pancreatic ribonuclease (RNase) containing two or three tyrosine chains with an average of two to three residues per chain have been prepared. The effects of various perturbants such as neutral salts, ethanol, urea and guanidine hydrochloride on the thermal transition of the derivatives have been studied....

Human exposure to polycyclic aromatic hydrocarbons : global cancer risk and metabolism

Creator:: Motorykin, Oleksii
Abstract:: In recent decades, there has been increased attention on human exposure to, and subsequently toxicity of, Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are widespread organic pollutants and some have been shown to be toxic, carcinogenic and mutagenic. This research was focused on understanding the link between global PAH emissions and lung...

The Local Structure of Functional Electroceramics

Creator:: Culbertson, Charles M.
Abstract:: This work investigates the relationship between the local structure and physical properties of a set of classical (MgTiO3, CaTiO3, SrTiO3, and BaTiO3) and complex ((1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3[BZT-BCT], Na0.5Bi0.5TiO3 [NBT]) perovskite electroceramics. The materials in this work were synthesized via standard solid state ceramic synthesis, the structure was investigated through a number of...

Approaches to the total synthesis of verrucarol

Creator:: Hill, David E. (David Edwin) 1954-
Abstract:: Verrucarol is the sesquiterpene portion of a number of macrocyclic di- and triesters of potential medicinal importance. In this study, a novel approach to the synthesis of this fungal metabolite is presented. An A-B-C route was investigated in which C-3 and C-4 of the C-ring were emplaced using a [2+2]...
