The American oyster (Crassostrea virginica) as a bioindicator of trace organic contamination
(Texas A&M University. Libraries, 1993)This study was designed to examine the uptake and depuration of trace organic contaminants, e.g. poly nuclear aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), including planar congeners, and butyltin species, ... -
Catalytic conversion of methanol to low molecular weight hydrocarbons
(Texas A&M University. Libraries, 1979)The recent demands on the avialable energy have stimulated the search for alternatives to oil. Methanol, because of its abundance and the availability of technology to produce it from coal, is projected as an alternative ... -
Gas phase radicals formed on metal oxide surfaces
(Texas A&M University. Libraries, 1981)The formation of gas phase radicals during the partial oxidation of propylene, 1-butene, isobutylene, and methane over several metal oxides was investigated. The radicals were isolated by employing a matrix isolation unit ... -
The growth, respiration and energetics of Mysidopsis almyra (Crustacea :Mysidacea) in relation to temperature, salinity and hydrocarbon exposure
(Texas A&M University. Libraries, 1981)A total of 6,924 individual mysids (Mysidopsis almyra) were divided among 249 combinations of temperature (20, 25 and 30(DEGREES)C), salinity (10, 20 and 30 ppt), South Louisiana crude oil water soluble fraction (WSF) ... -
Immunotoxicity of the halogenated aromatic hydrocarbons- QSARs and interactive effects
(Texas A&M University. Libraries, 1989)The role of the aryl hydrocarbon (Ah) receptor in mediating the immunosuppressive effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) and related halogenated aromatic hydrocarbons (HAHs) on the murine splenic ... -
An improved equation of state for gaseous hydrocarbon mixtures
(Texas A&M University. Libraries, 1961)Performance prediction calculations for petroleum reservoirs existing at high temperatures and pressures require the use of a compositional material balance. The compositional balance in turn requires a method of calculating ... -
Interactions between petroleum hydrocarbons and the polychaetous annelid, Neanthes arenaceodentata : effects on growth and reproduction, fate of diaromatic hydrocarbons accumulated from solution or sediments
(Texas A&M University. Libraries, 1976)The effects of water soluble fractions (WSFs) from No. 2 Fuel Oil on growth and reproduction in a laboratory strain of Neanthes arenaceodentata (Moore, 1903) were studied in experiments simulating conditions of acute and ... -
Interactive effects of physical factors and hydrocarbon exposure on the survival, development rate and growth of the mud crab Rhithropanopeus harrisii and the horseshoe crab Limulus polyphemus
(Texas A&M University. Libraries, 1977)Embryos and juveniles of the horseshoe crab, Limulus polyphemus were exposed continuously to 0, 5, 10, 25 and 50% Water-Soluble Fractions (WSF) of no. 2 fuel oil at temperatures of 20°, 25° or 30° C and one salinity, 32 ... -
Light hydrocarbons in marine sediments
(Texas A&M University. Libraries, 1978)Concentrations of the C₁-C₃ hydrocarbons and stable carbon isotope compositions of methane in recent sediments and seep gases of the Texas-Louisiana shelf-slop region were determined. These gases have been produced by both ... -
The selective functionalization of saturated hydrocarbons with GIF-type systems
(Texas A&M University. Libraries, 1992)The Gif-family is a group of Fe- or Cu-containing chemical systems oxidizing saturated hydrocarbons to ketones. The unusual behavior shown by these systems (secondary C-H bonds are oxidized preferentially even in the ... -
Selective oxidation of olefins over transition metal-exchanged zeolite Y
(Texas A&M University. Libraries, 1979)The selective oxidation of olefins including oxidative dehydrogenation and epoxidation reactions over transition metal-exchanged zeolite. Y at mild reaction conditions was investigated. This dissertation describes the ... -
Studies on criticality phenomena and collinearity constraints
(Texas A&M University. Libraries, 1987)This dissertation intends to provide new and efficient tools to improve fluid phase equilibria predictions using equations of state (EOS) and various mixture combining rules (MCR). We developed, and successfully tested, a ... -
Synthesis, chemical and NMR spectral studies of 1,7,7-trimethyl-2,3-benzobicyclo[3.3.1]non-2-enes
(Texas A&M University. Libraries, 1978)A detailed NMR study has been made into the preparation, structure and characterization of a series of 1,7,7-trimethyl-2,3-benzobicyclo[3.3.1]non-2-enes. This family of compounds was derived from the parent structure, A, ... -
The ultrastructure and hydrocarbons of Botryococcus braunii Kützing (Chlorophyceae)
(Texas A&M University. Libraries, 1981)The ultrastructure of resting state colonies of Botryococcus braunii Kutzing from two localities is compared to active state colonies maintained in the laboratory. Qualitative hydrocarbon analyses confirmed the physiological ... -
Volatile liquid hydrocarbons in the marine environment
(Texas A&M University. Libraries, 1978)Concentrations of volatile liquid hydrocarbons (VLH), C ₆- C ₁₄ hydrocarbons, were determined in coastal, shelf and open ocean surface waters of the Gulf of Mexico. Open ocean, non-petroleum polluted surface water VLH ...
