Creator:: Carter, Richard Thomas
Abstract:: The female Philometra americana Ekbaum, 1933 is a common subcutaneous parasite of the starry flounder, Platichthyes stellatus (Pallas) of Yaquina Bay, Lincoln County, Oregon.

Phospholipids of Tenebrio molitor larvae

Creator:: Kamienski, Francis Xavier
Abstract:: Phospholipids of Tenebrio molitor larvae were separated on columns of DEAE-cellulose and silicic acid-Hyflo Super Cel. The major phosphatide components were identified by various analytical procedures. Phosphatidyl choline was demonstrated to be the predominant phospholipid with a high percentage of phosphatidyl ethanolamine. A small amount of inositol-containing phosphatides were present....

Generalization of the Ostrowski-Schneider main inertia theorem

Creator:: Hill, Richard David
Abstract:: As indicated by the title, this thesis generalizes the Main Inertia Theorem of Ostrowski and Schneider [8]. The first three results concern the formation of a polynomial function f(A, A*, H) so that the existence of an hermitian H for which f(A, A*, H) is positive definite is a necessary...

An illustrated key to the ferns of Oregon

Creator:: Pembrook, Helen Patricia O'Donahue
Abstract:: The purpose of the work is to enable students of botany to identify accurately Oregon ferns, both as living plants and as dried specimens. Therefore, it provides vegetative keys to the families, genera and species of the ferns (Class FILICINAE) found in Oregon. Correct names have been determined using the...

Fungitoxicity of sodium n-methyldithio-carbamate (Vapam) and its decomposition products

Creator:: Elson, Joseph Earl
Abstract:: An assay for fungicidal activity of sodium N-methyldithiocarbamate (Na-MDC) and its decomposition products was developed in which there was a minimum influence due to the widely varying physical properties of the compounds (i.e. vapor pressure and water solubility). Decomposition of the toxicant during the tests was measured and held to...
