Quantitative basin morphology and channel stability with reference to nonpoint sources of pollution in Evans Creek, Oregon

Creator:: Krupin, Paul J.
Abstract:: A Stream Reach Inventory and Channel Stability Evaluation procedure has been used to assess the nature and extent of erosional nonpoint sources of pollution in the Evans Creek basin, a tributary to the Rogue River, in southwestern Oregon. The study is based upon the results of the Oregon Department of...

The effect of games on cognitive abilities and on attitudes toward mathematics

Creator:: Henry, Kermit Maxson
Abstract:: The purpose of this investigation was to determine if either of two selected commercial games, when used by seventh-grade mathematics teachers, would significantly improve students' (1) attitudes toward mathematics, (2) quantitative cognitive abilities, and (3) nonverbal cognitive abilities. Equations, a mathematics game, and Tac-Tickle, a strategy game, were chosen as...

Science for the societally liabiled : the effect of a preliminary language-technique course upon academic success

Creator:: Henderson, Gwendolyn Witherspoon
Abstract:: The study was undertaken to determine if a university-level preliminary class concentrating upon the formalism and techniques germane to success in science would serve to improve minority academic performance, minority here being defined to include certain Asian Americans, Black Americans, Native Americans, Spanish surnamed Americans, and those white Americans who...

The glutamine synthetases in soybean root nodules and free-living Rhizobium japonicum

Creator:: Guevara, Juan Garcia
Abstract:: Glutamine synthetase activity is present in both the cytosol and bacteroid fractions of soybean root nodules. Total activity measurements indicate that at least 90% of the activity in nodules is located in the cytosol. Results reported by McParland, et al. (29), showed that many properties of glutamine synthetase from nodule...

An investigation of the metabolism of poly-β-hydroxybutyrate and its possible role in nitrogen fixation in soybean root nodules

Creator:: Wong, Peter Pasteur, 1941-
Abstract:: A major objective of this investigation was to determine the possible roles, if any, of poly-β-hydroxybutyrate and products of its metabolic breakdown in symbiotic nitrogen fixation by nodule bacteroids. Changes in poly -β- hydroxybutyrate content and in activities of nitrogenase, β-hydroxybutyrate dehydrogenase, and isocitrate lyase were studied under various conditions...

The effects of cadmium on the nitrogen fixation system in Alnus rubra

Creator:: Wickliff, Carlos
Abstract:: Alnus rubra (Bong. ) seedlings were grown in sand culture and irrigated with nutrient solution containing CdCl₂ ranging from 5 μg to 100 mg per liter. Treatment of A. rubra seedlings for 4 weeks with 50 and 100 mg CdCl₂ per liter of nitrogen-free nutrient solution decreased in situ nitrogenase...

A biochemical investigation of the nitrogenase system from soybean root nodules

Creator:: Koch, Burton Lee
Abstract:: The primary purpose of this investigation was to determine the conditions necessary for the preparation of cell-free extracts of nodule bacteroids capable of catalysing the reduction of acetylene to ethylene and nitrogen to ammonia. Initial investigations were conducted to determine whether intact soybean root nodules would reduce acetylene to ethylene...

Nitrogen fixation associated with grasses and other species in Oregon

Creator:: Nelson, Arthur Duane
Abstract:: Nitrogen fixation in both natural and domestic grasslands of Oregon was studied using the acetylene reduction assay. A substantial number of these tests made gave positive acetylene reduction activity. Rates in the range of 60g N₂ fixed/ha/day were observed for some Agrostis species. Assuming that this rate proceeds for 100...
