Some aspects of the biological metabolism of a partially colloidal substrate

Creator:: Berg, Richard Harold
Abstract:: An investigation was conducted to ascertain if certain concepts of microbial metabolism, derived from studies using simple soluble substrates, are applicable to the biological assimilation of complex, partially colloidal suspensions. A mixture containing one gram of Carnation dry-skim milk is considered to be a complex, partially colloidal substrate and was...

Formation of N-nitrosamines from the nitrosation of spermidine and spermine

Creator:: Hildrum, K. I. (Kjell Ivar), 1940-
Abstract:: The reactions between sodium nitrite and the polyamines spermidine and spermine were investigated. When reacted at 80°C for 1 hr at pH 3.5 with a 1:3 molar ratio of amine groups to sodium nitrite, five volatile nitrosamines were identified as products in the nitrosation of spermidine. 3HC1, and two volatile...

Phyto-edaphic relationships and ecotypic development of Festuca idahoensis in eastern Oregon habitat types of Artemisia tridentata

Creator:: Doescher, Paul Steven
Abstract:: This research assessed certain specific plant-soil and community interrelationships in eastern Oregon habitat types dominated by subspecies of Artemisia tridentata. The first evaluation described plant-induced soil chemical patterns for Artemisia tridentata plant communities of high perennial grass-low shrub and low perennial grass-high shrub composition. Soil concentrations of total nitrogen, organic...

Intracellular pH and the uptake of carcinostatic drugs by selected experimental tumors

Creator:: Hult, Richard Lee
Abstract:: The relationship of intracellular drug levels and resultant drug activity to intracellular pH (pHi) was studied in the experimental tumors. Glucose (5 g/kg) and/or sodium oxamate (0.1 mmol) were administered to Walker 256 ascites cells and Ehrlich ascites cells, in an attempt to alter pHi as measured by the distribution...

Oregon's Mid-Willamette Valley wetlands : agricultural uses, alternative uses, problems and trends

Creator:: Tsutsui, Setsuo Harry
Abstract:: The wetlands are distinguished from other lands of the Mid-Willamette Valley by excessive soil moisture. The wetlands, as defined for this study, consist of 20 soil series (in 22 soil mapping units) which are classified by the Soil Conservation Service as having excessive wetness as the major factor limiting their...

Paleomagnetism and secular variation of Easter Island basalts

Creator:: Isaacson, Laurie Brown
Abstract:: The paleomagnetic history of the volcanic rocks of Easter Island was investigated using standard paleomagnetic techniques. The remanent magnetization of 673 specimens from the three volcanic episodes recognized on the island were measured using a spinner magnetometer. Inclinations, declinations and virtual geomagnetic poles were calculated for each flow. The majority...

An evaluation of expressed level of aspiration as a determinant of performance in an undergraduate biology course

Creator:: Pearce, Richard Mott
Abstract:: The purpose of this investigation was to determine if the level of aspiration procedure consisting of knowledge of results plus goal-setting possesses a motivational property as reflected in performance on subject matter criterion instruments above that of knowledge of results alone in an undergraduate biology course. In addition the study...
