Deterioration of gallium arsenide diodes

Creator:: Matsuo, Samuel Seiji
Abstract:: Changes in the diode characteristics of three different types of diodes were studied. These were point-contact, bonded and zinc-diffused diodes. The parameters in which measurable changes were observed were the forward resistance, the reverse breakdown voltage, the forward "knee" of the diode curve and the constant of proportionality relating the...

Properties of flash-evaporated gallium arsenide and gallium phosphide epitaxial films

Creator:: Matsuo, Samuel Seiji
Abstract:: The properties of flash- evaporated films of GaAs and GaP were studied in this investigation. Films were grown at various substrate temperatures, source temperatures, source-to-substrate distances and rates of deposition and were evaluated as to their structural, optical and electric properties. It was found that substrate temperature was the major...

Studies on the interaction of polylysine with deoxyribonucleic acid

Creator:: McKenzie, Raymond Leslie
Abstract:: The interaction of polylysine with DNA may be divided into two separate phenomena: the primary interaction involved in formation of a well-defined complex, and secondary interactions leading to aggregation of these complexes. Most studies on the interaction of polylysine with DNA have used techniques which measure properties of the aggregated...

The interaction of polylysine with DNA as studied by polarization of flurescence

Creator:: Evett, Jay Fredrick
Abstract:: A fluorescent dye, 1-dimethylaminonaphthalene-5-sulfonyl chloride (dansyl chloride), was covalently bonded to polylysine. The dansyl tagged polylysine was complexed to DNA by gradient dialysis. The polarization and intensity of fluorescence of the dansyl and the turbidity of the complex were measured as a function of salt concentration for a variety of...

In vitro inhibition of lipase activity by malonaldehyde, formaldehyde and propionaldehyde

Creator:: Landsberg, Johanna Dobrot
Abstract:: The reactions of aldehydes with proteins are of nutritional and physiological significance. The nutritive value of food materials can be impaired by a reaction necessitating additional dietary protein, and enzymes have been shown in vitro to be inhibited by reactions with aldehydes. Aldehydes present may arise from the autoxidation of...

Characterization of interferon and retroposon-like repetitive elements in salmonid fish

Creator:: Tengelsen, Leslie A.
Abstract:: Hatchery-reared salmonid fish routinely encounter stress due to handling, barging, tagging, and overcrowding. It has been demonstrated that there exists a direct correlation between stress and transient immune suppression which can last for many days in fish. Epizootic viral infections routinely appear in hatcheries and can have a devastating effect...

Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

Creator:: Alemu, Yagenetfere A.
Abstract:: The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...

A Public Elementary School as a Cultural Context : Japanese Children Learning to Perceive their Environment

Creator:: Sugai, Taichi
Abstract:: This thesis examines the cultural context in which Japanese children are constructing their own perspective of the environment because in the development of environmental education in Japan, the perspectives of children and teachers have not been taken into consideration. Although educators have made efforts to give direction to environmental education,...

Portlandia's Other Children : Refugee Communities in Urban Life

Creator:: Kubein, Adele M.
Abstract:: This research analyzes the relations of ethnic refugee communities and particularly their businesses to gentrification and community vitality in a neighborhood in Portland, Oregon. The data indicates that gentrification is not a linear process of displacement of African Americans by Whites seeking affordable housing and new frontiers, but rather is...
