Isolation and partial characterization of temperature sensitive division mutants of Chlamydomonas reinhardtii

Creator:: Wolff, Darold Melvin, 1940-
Abstract:: The primary objective of this study was to develop methods for the selection of temperature sensitive division (TSD) mutants of Chlamydomonas reinhardtii. Such methods were developed and four temperature sensitive (TS) mutants were isolated and partially characterized. Wild type (WT) cells of the plus mating type were synchronized by a...

Urea release from sulfur-coated urea and nitrogen utilization by tall fescue

Creator:: Pettygrove, G. Stuart
Abstract:: Sulfur-coated urea (SCU), a slow release nitrogen fertilizer, may be economically competitive with conventional fertilizers, but little is known of the mechanism of urea release from SCU and the environmental factors which affect the urea release rate. Objectives of this thesis were: (1) to determine factors which affect the rate...

Studies on some digenetic trematodes from Ritner Creek, Polk County, Oregon

Creator:: Law, Daniel Tin-Hung
Abstract:: Seven species of fresh water fishes belonging to three different families and two species of snails from Ritner Creek, Polk County, Oregon were surveyed for adult and larval trematodes. A total of seven species of trematodes representing four families was recovered from the intestine of the fishes. Of these, at...

The relationship of lysosomal stability to radiation-induced delay of cell division in Tetrahymena pyriformis

Creator:: Hodge, Frederick Allen
Abstract:: Cell division in a heat synchronized Tetrahymena pyriformis (GL-I) cell can be delayed if the cell is exposed to X-irradiation (300 kVp, 20 mA, HVL = 0. 9 mm Cu, 25 R/ sec) prior to a critical time after the end of the synchronizing treatment (EST). At the critical time,...

Pathogenicity of experimentally induced concurrent infections of Fasciola hepatica and Haemonchus contortus in sheep

Creator:: Presidente, Paul J.
Abstract:: Twenty yearling sheep were allotted to four groups, each containing five sheep of approximately equal weight. On experimental days 0, 1, 2, 3, and 4, each sheep in each group was given the following inoculations by stomach tube: five sheep in group I (Fasciola hepatica-exposed controls) were given approximately 120...

The effect of ultra-high pressure on the emf of thermocouples

Creator:: Eide, Stuart Ames
Abstract:: The effect of ultra-high pressure on the thermal emf of a chromelialumel thermocouple is investigated using an indirect method which does not require a direct knowledge of the temperature of the pressurized junction. The unknown temperature is written parametrically as a function of a directly measured quantity, the electrical power...

Sphaeromyxa maiyai sp. n. (Protozoa:Myxosporidea) : a light microscopic and ultrastructural analysis employing the scanning and transmission electron microscopes

Creator:: Morrison, N. Donald
Abstract:: Sphaeromyxa maiyai sp. n. (Myxosporidea:Myxiidae) is described from the gall bladder of the Pacific tomcod, Microgadus proximus Girard, from Newport, Oregon. The plasmodial (=trophic, trophozoite) stage is discoid averaging between 1 and 2 cm. The spore averages 27.6 x 5. 6μm with pyriform polar capsules averaging 9. 3 x 3....

Transconjugant analysis : the limitations on the use of sequence-specific endonucleases for plasmid identification

Creator:: Causey, Stuart Crowell
Abstract:: We have used the sequence-specific endonucleases Eco RI, Sma I, Bam HI, Hsu I and Hae III as identification tools in following the conjugal transfer of the well studied R plasmids Sa, R388, RP4 and R6K. Transfers were both intergenus and intragenus. Plasmid fingerprints were generated from both single and...

The effect of hypothermia on biochemical and morphological aspects of carbon tetrachloride hepatotoxicity

Creator:: Kaufman, Stuart Neil
Abstract:: The temporal relationships among selected correlates of hepatocellular damage were investigated in cordotomized, hypothermic rats intoxicated with carbon tetrachloride (CC1₄). Rats were spinally transected between C6 and C7 and allowed to become hypothermic. CC1₄ (1.25 ml/kg ip) was administered as a 1:1 solution in corn oil. Plasma alanine aminotransferase (ALT)...
