Growth, fabrication and modeling of pseudomorphic laser diodes

Creator:: Ebner, John
Abstract:: This thesis reports on the crystal growth, fabrication, modeling and performance of Graded Index-Separate Confinement Heterostructure laser diodes which contain pseudomorphic InGaAs as the active region material. Laser epitaxial layers were grown with different indium mole-fractions, and a constant InGaAs layer thickness of 10 nm, on both sides of the...

The synthesis and electrocyclization of some linear and cross-conjugated hexatrienes

Creator:: Hilton, Charles Bruce
Abstract:: As part of the continuing investigation of the thermal cis- 1, 3, 5-hexatriene to 1,3-cyclohexadiene rearrangement, four new trienes and a cross-conjugated pentaene have been prepared and their thermal reactions studied. A new route to the synthesis of highly substituted trienes has been developed. The synthesis of three of these...

The purification and characterization of the fructose-1, 6-diphosphate aldolase from Bacillus stearothermophilus (NCA 2184)

Creator:: Quinn, Richard Paul
Abstract:: The thermophilic aldolase from Bacillus stearothermophilus (NCA 2184) has been purified to a specific activity of 45.5 μ-moles of fructose-1, 6-diphosphate cleaved per minute per mg of enzyme, representing a 624-fold increase over the crude extract. The preparation appeared to be homogenous by sedimentation velocity ultra-centrifugation and by a specific...

Habitat utilization by spotted owls in the West-Central Cascades of Oregon

Creator:: Forsman, Eric D.
Abstract:: Eight adult spotted owls (Strix occidentalis) on the west slope of the Cascade Range in Oregon were fitted with radio transmitters and observed for periods ranging from 271 to 383 days. Mean home range size for the owls was 1,177 ha (range = 920-1,376 ha). There was no significant difference...

Spectrophotometry of molybdenum, tungsten and chromium chelates of quercetin

Creator:: Mitchell, Lloyd James
Abstract:: Quercetin (3, 3', 4', 5, 7-pentahydroxyflavone) reacts with hexavalent molybdenum, tungsten and chromium to form chelates soluble in an ethanol-water medium. This color reaction has been investigated with a view to its possible application in the spectrophotometric determination of trace amounts of these metals. In the development of the method,...

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...

Kinetics of thermal decomposition of tungsten hexacarbonyl

Creator:: Knapp, Samuel Boyd
Abstract:: The thermal decomposition of tungsten hexacarbonyl was investigated in an apparatus which allowed a solid sample of the material to be sealed into a preheated batch reactor. Because the reaction occurs with an increase in the number of moles of gas, it was possible to monitor the progress of the...

The conversion of some monoalkylhydrazines to their corresponding hydrocarbons by a hepatic microsomal enzyme system in rat

Creator:: Prough, Russell A.
Abstract:: An aspect of the metabolism of monoalkylhydrazines has been investigated using both intact rats and rat liver microsomal enzyme preparations. Intact rats respired propane and n-butane on administration of 0.3-0.5 mmoles of isopropyl- and n-butylhydrazine, respectively. Based upon dose administered, a five to ten percent yield of hydrocarbon was obtained....

Glutamate dehydrogenase : I.Flourescence polarization studies of the self-association. II.Flourescence and circular dichroism studies of the heterotropic interactions

Creator:: Malencik, Dean Anthony
Abstract:: Fluorescence polarization measurements on beef liver glutamate dehydrogenase conjugated with pyrene butyric acid demonstrate that the association of the enzyme is adequately described by a reversible indefinite association with a single equilibrium constant. The data obtained with protein concentrations up to 0.7 mg/ml in 0.05 M potassium phosphate, pH 7....
