Efficiency of thorium extraction by primary amines as a function of pulse frequency and amplitude in a pulsed sieve-plate column

Creator:: Davis, Bernard Eric, 1937-
Abstract:: The amine extraction process is evaluated for pulse column operation. A 0.1 M solution of Primene JM-T (a commercial mixture of tertiary-alkyl primary amines) in a kerosene-base diluent is the extractant for thorium feed in aqueous acidic sulfate solutions. Equilibrium isotherms at room temperature are presented at aqueous acidities of...

The biosynthesis of terpenes in Pelargonium graveolens

Creator:: Allison, Robert David
Abstract:: Pelargonium graveolens Ait., rose geranium, contains several oxygenated monoterpenes, most of which are related to each other structurally. In this work, the metabolism and interconversions of these terpenes was investigated. A chromatographic analysis of geranium oil was performed initially for the purposes of identifying the terpenes and determining which chromatographic...

The effects of water withdrawals on the emergence timing, adult body mass, and total emerging biomass of aquatic insects from two northeast Oregon rivers

Creator:: Brown, Phil D.
Abstract:: Small low-head diversion dams are capable of removing much of the flow of a river, often resulting in increased water temperatures and habitat loss. Warmer temperatures have been shown to accelerate aquatic invertebrate growth and development, and discharge reductions can reduce instream habitat, suggesting that water withdrawals may alter both...

A State of Practice of Safety and Big Data in Transportation Engineering Curricula and in Transportation Design : How is it Used and How can Academic Offerings Better Represent Industry Practices?

Creator:: Castro, Edgar D.
Abstract:: Improving safety education could contribute to the preparation of better professional engineers. Safety topics are not holistically embedded in transportation course curricula. This thesis explores the current state in which safety is being incorporated in transportation course curricula in terms of design and compares the uses of safety data in...

Carcinogenicity and acute toxicity of dimethylnitrosamine in rainbow trout (Salmo gairdneri)

Creator:: Grieco, Mary Porter
Abstract:: A dose related carcinogenic response was established for dimethylnitrosamine administered in the diet of rainbow trout (Salmo gairdneri). An equation was derived for the relationship between dose and hepatocellular carcinoma incidence. From a published dose response study using Porton rats as a test animal, a second equation was derived for...

Effect of site and silvicultural treatment on insect pests and diseases of young ponderosa pine

Creator:: Norlander, Daniel W. D.
Abstract:: Ponderosa pine is an important species both commercially and ecologically in western North America. This study considers the incidence of insect and disease pests on a series of replicated ponderosa pine research plantations in northern California. The studies, on an environmental gradient, contain a series of silvicultural treatments including vegetation...

Student Engagement : Exploring How and Why Students Engage In- and Out-of-Class

Creator:: Pascoe, Jason J.
Abstract:: Student engagement in a course plays a vital role in a student’s ability to process and construct knowledge. Student engagement research has investigated how students engage in and out of the classroom on a macro scale, through observation and survey data collection of large student populations, which lack focus on...
