Aroma-active compounds in 'Centennial', 'Citra' and 'Nelson Sauvin' hop varieties and their aroma contribution to dry-hopped beer

Creator:: Feng, Shi
Abstract:: The objectives of this study were to 1) measure and compare the compositional differences of essential oil among three hop cultivars ('Centennial’, 'Citra' and 'Nelson Sauvin'), 2) identify the odor-active aroma compounds in three varieties of hops and 3) investigate the behavior of hop-derived aroma compounds in beers prepared by...

Ecological Forestry : A Critical Analysis

Creator:: Batavia, Chelsea
Abstract:: Although science is widely accepted as a fundamental source of information underlying decisions about forest management and conservation, considerably less attention has been paid to the inevitable role that normative values and beliefs play in such decisions. This thesis highlights the normative dimensions of "ecological forestry," a strategy of forest...

Preparation and laboratory evaluation of stationary-phase iron-oxide-based adsorbents for removal of metals from waste waters

Creator:: May, Michael Lee
Abstract:: Several potential sorbent materials containing iron oxides were prepared and evaluated for potential to remove divalent metals from waste waters. These included a ferrihydrite-coated sand, maghemite incorporated in Dowex[Trademark] ion exchange resin, gothite and two thermally activated ferrihydrites. Attempts to prepare sorbents from steel shot by coating with ferrihydrite or...

Oregon coastal lake study : phosphorus loading and water quality implications

Creator:: Blair, Michael Stuart
Abstract:: A study of phosphorus loading and water quality implications was conducted for the Oregon coastal lakes. The study was based on existing data for lake total phosphorus concentrations and for watershed land uses. A phosphorus mass-balance model was developed to predict lake total phosphorus concentrations from estimated phosphorus loading from...

Phylogeny and Evolution of Gall-Associated Plant Pathogenic Bacteria

Creator:: Davis, Edward W., II
Abstract:: Gall-associated phytopathogens have unique evolutionary histories that haveshaped both their modes of infection and genomic structures. Pathogenicity of the gall-associated plant pathogens of the Rhodococcus, Agrobacterium, and Rathayibactergenera is mediated by horizontally acquired virulence loci. The relative ease of gainand loss of the virulence loci has confounded accurate characterization of...

The peppermint industry : situation and outlook with emphasis on Oregon

Creator:: Matzat, James H.
Abstract:: The peppermint industry is the largest commercial herb industry in the United States. Oregon is the largest peppermint producing state with nearly 60 percent of the total United States peppermint oil production. There is a need for economic information about current and future prospects for the national peppermint industry as...

The effects of land use on stream nitrate concentrations : from the catchment scale to the regional scale

Creator:: Poor, Cara J.
Abstract:: This work furthers the understanding of processes occurring in catchments that affect stream nitrate concentrations using two different approaches: a temporally intensive case study of three headwater catchments with varying land use (through storm event monitoring) and a spatially intensive study on the regional scale (through statistical modeling) of 1st-4th...

Reproductive isolation and interspecific hybridization in the threatened species, Sidalcea nelsoniana

Creator:: Gisler, Steven D.
Abstract:: In addition to its longstanding recognition as an influential evolutionary process, interspecific hybridization is increasingly regarded as a potential threat to the genetic integrity and survival of rare plant species, manifested through gamete wasting, increased pest and disease pressures, outbreeding depression, competitive exclusion, and genetic assimilation. Alternatively, hybridization has also...
