Late Quaternary radiolarian paleo-oceanography of the Panama Basin, eastern equatorial Pacific

Creator:: Dinkelman, Menno Gustaaf
Abstract:: A total of 57 core top samples from the Panama Basin were used in a quantitative study of complete radiolarian thanatocoenoses to determine whether surface oceanographic conditions are reflected in the microplankton faunas deposited onto and buried in the sea floor. Information obtained from this study was used to resolve...

The estimation of regional secondary benefits resulting from an improvement in water quality of upper Klamath Lake, Oregon: an interindustry approach

Creator:: Reiling, Stephen D.
Abstract:: The primary objective of this study was to estimate the impact that an increase in recreational expenditures, resulting from water quality improvements of Klamath Lake, would have upon the Klamath County economy. As the sales of the economy expand to serve the needs of the recreationists, real benefits will be...

Synthesis of novel ambifunctional atropisomeric 2,2',6,6'-tetrasubstituted biphenyls and investigation of their properties and organocatalytic activity

Creator:: Sephton, Mark Alan
Abstract:: Ambifunctional axially chiral 2,2',6,6'-tetrasubstituted biphenyls containing nucleophilic (or basic) functional groups juxtaposed with hydrogen-bond donors were synthesized and their properties studied. Applications for the prepared biaryls as potential organocatalysts for enantioselective carbon-carbon bond forming reactions were examined. Processes investigated included: aldol, Michael, nitroaldol (Henry), and Baylis-Hillman reactions. The novel amidoamine...

A low cost AC motor drive for battery powered applications

Creator:: Wiley, Brian
Abstract:: Environmental concerns have renewed the interest in electric vehicles. To gain widespread use, electric vehicles will also have to offer good performance and be reasonably priced. AC drive systems using modern semiconductors can provide efficient operation at the required power levels, but their cost at present is still too high....

Mapping dose rate of the Oregon State University neutron radiography facility

Creator:: Ropon, Kimberly
Abstract:: The Department of Nuclear Engineering at Oregon State University has recently introduced a neutron radiography facility (OSNRF). The facility is dependent on a neutron source established by the OSU TRIGA® Reactor (OSTR). It was unknown how accurately a computerized model of the OSTR in conjunction with the OSNRF could represent...

Synthetic studies of nonadrides

Creator:: Drapela, Nicholas Ernest
Abstract:: An asymmetric approach to the synthesis of byssochlamic acid (1) is described. Regioisomeric enzymatic differentiation is described in the selective hydrolysis of dimethyl ester 30 by porcine liver esterase. Chiral dimethyl ester 42 was prepared by desymmetrization of cyclopentene 34 using porcine liver esterase. A key intramolecular [2+2]cycloaddition-cycloreversion photometathesis of...

Evaluation and use of a soil mineralizable nitrogen test to determine the fertilizer nitrogen needs of winter wheat grown in western Oregon

Creator:: Baloch, Dost M.
Abstract:: The assessment of optimum nitrogen (N) fertilizer need for winter wheat (Triticum aestivum L.) is important for economic and environmental sustainability. A comprehensive understanding of fertilizer N requirement depends on estimation of the quantity of N needed by the crop versus that supplied by soil. The objectives of this study...

Simple sequence repeat marker development and use in European hazelnut (Corylus avellana L.)

Creator:: Gürcan, Kahraman
Abstract:: New highly polymorphic simple sequence repeat (SSR) markers for European hazelnut (Corylus avellana L.). were developed from several sources. The markers were characterized, and segregation in a mapping population allowed to assign them to linkage groups. Their transferability across genera and species in the Betulaceae family was investigated. SSR markers...
