Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

Creator:: Carlson, Erik
Abstract:: Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

Efficiency of forest vegetation control with herbicides

Creator:: Fredrickson, Edward A.
Abstract:: Selective suppression of crown and root sprouting of non-coniferous cover are the keys to effective forest vegetation management. This study 1) develops insight into mechanisms of controlling root suckering and top regrowth of bear clover (Chamaebatia foliolosa), and develops a broad data base for controlling broad groups of vegetation chemically....

Fifth-year growth responses of Douglas-fir to crowding and other competition

Creator:: Cole, Elizabeth C.
Abstract:: This thesis examines the competitive aspects of Douglas-fir trees growing with two commonly associated competitors--red alder and grass--at varying densities. Two Nelder plots in three different environments in the Oregon Coast Range were studied. The sites represented the warm, dry climate of the Willamette Valley; the warm, moist climate of...

Development of volatile composition and C₁₃-norisoprenoid precursors in Pinot noir grape, Development of volatile composition and C13-norisoprenoid precursors in Pinot noir grape

Creator:: Yuan, Fang
Abstract:: This study first investigated the developmental changes in the volatile composition and carotenoids of Pinot noir grapes. Grape berries were sampled every week from pea size to harvest during the 2011 and 2012 season. Carotenoids and organic acids were analyzed by HPLC. Volatile compounds were extracted from crushed berries using...

Nitrogen management and variety selection for dryland production of hard red winter wheat in northeastern Oregon

Creator:: Jepsen, Daniel R.
Abstract:: Proper nitrogen (N) management and variety selection are important for profitable hard red winter (HRW) wheat production in the dryland growing regions of northeastern Oregon. In these dryland systems, N management for grain yield and grain protein concentration (GPC) is challenging due to climatic and year-to-year variation in production environments....

The effect of wine matrix on the analysis of volatile sulfur compounds by solid-phase microextraction-GC-PFPD

Creator:: Davis, Peter M.
Abstract:: Constituents of the wine matrix, including ethanol, affect adsorption of sulfur volatiles on solid-phase microextraction (SPME) fibers, which can impact sensitivity and accuracy of volatile sulfur analysis in wine. Several common wine sulfur volatiles, including hydrogen sulfide (H2S), methanethiol (MeSH), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS), diethyl...

An evaluation of two methods for determinations of polynuclear aromatic hydrocarbons in water

Creator:: Schaffer, Randy Lee
Abstract:: Research has been completed that evaluates two methods for the extraction of polynuclear aromatic hydrocarbons (PNAH) from water. The two methods compared were EPA Method 610, a liquid-liquid extraction method, and a method involving PNAH adsorption on commercially available short C₁₈ bonded phase columns, Sep-Paks, in series with glass microfiber...

Impacts of dredged material disposal on estuarine benthic macrofaunal communities in Coos Bay, Oregon

Creator:: Erman, Lisa T.
Abstract:: Hopper dredge disposal of coarse grained sediment was investigated between May and September, 1986, at a designated disposal area, Site G, in Coos Bay, Oregon. The objectives of the study were to: (a) identify and describe the benthic macrofaunal community structure at Site G during May and September, 1986; (b)...

The effects of tritiated seawater on development of the goose barnacle Pollicipes polymerus

Creator:: Abbott, David Thomas
Abstract:: The purpose of this study was to determine the effects of tritiated seawater (HTO) on selected developmental stages of the goose barnacle, Pollicipes polymerus. Barnacle embryos were cultured in Millipore cytology monitors with HTO concentrations of 0, 10⁻⁵, 10⁻³, 10⁻¹, and 10¹ μCi/ml. After 22 days, hatching was complete and...

Flavor composition of transgenic raspberry bushy dwarf virus-resistant 'Meeker' raspberries

Creator:: Malowicki, Sarah Marie-Mahler
Abstract:: Raspberries have been popular since the time of the ancient Greeks. Red raspberries are cultivated throughout the world, particularly in the Pacific Northwest region of the United States and Canada. The raspberry bushy dwarf virus (RBDV) causes significant reduction in yield and crumbly fruit in raspberries, blackberries and raspberry-blackberry hybrids....
