The effect of hopping technology on lager beer flavor and flavor stability and the impact of polyphenols on lager beer flavor and physical stability

Creator:: Aron, Patricia M.
Abstract:: Beer is one of the most extensively consumed beverages world-wide and it is almost always brewed with hops (Humulus lupulus, L.). Hops provide beer with bitterness, aroma, flavor and texture and also enhance specific beer properties such as foam stability, clarity (colloidal stability), color, flavor stability and microbial stability. Hops...

Chilling as a factor in crop location with particular reference to deciduous orchards in California

Creator:: Aron, Robert Henry
Abstract:: Several empirical formulas that may be used to estimate available chilling are presented in this study. Many climatic parameters were considered in the derivation of these formulas. One equation employing only maximum and minimum temperatures had a coefficients of correlation (R) and R² values of .978 and .957, respectively. This...

An ultrastructure study of oogenesis in the sea urchin, Strongylocentrotus purpuratus

Creator:: Chatlynne, Louise Geller
Abstract:: Oogenesis in the sea urchin Strongylocentrotus purpuratus was studied at the fine structural level, with special emphasis on the relationship between the two main cell types within the ovary: the egg cells and the nutritive phagocytes, or accessory cells. The nutritive phagocytes are flagellated cells with extensive pseudopods which store...

Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

Creator:: Clark, Darren A.
Abstract:: Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...

The morphological events during the self-reassembly of the sea urchin embryo in culture

Creator:: Hamada, Spencer Hiroshi
Abstract:: The gastrula of the sea urchin Strongylocentrotus purpuratus was dissociated into single cells. In culture these cells appeared apolar, but reassembled into quasi-normal embryos composed of structures with polarized cells. In this study emphasis was placed on those morphological events coincident with the reestablishment of a polar orientation within the...

Gender differences in the perceptions of sexual abuse

Creator:: Sandras, Eric
Abstract:: The purpose of this study is to explore gender differences in adult perceptions of sexual abuse encounters between an adult male and children of both genders and of various ages. Subjects were four hundred and fifty three students from a northwestern university. They were recruited from a lower-level human development...

Direct and indirect effects of livestock grazing intensity on processes regulating grassland bird populations

Creator:: Johnson, Tracey N.
Abstract:: In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...

Using Vineyard Floor Management to Manipulate Vine Vigor: Impacts on 'Pinot noir' Yield Productivity and Fruit Composition

Creator:: Reeve, Alison L.
Abstract:: Winegrapes are an important crop for Oregon agriculture, ranking amongst the top ten agricultural commodities based on farmgate value. The most widely planted winegrape cultivar in the state is ‘Pinot noir’ (Vitis vinifera L.), and the majority of acreage is produced in the Willamette Valley. Production of quality ‘Pinot noir’...

Dynamics of organic matter production and degradation during coastal diatom blooms

Creator:: Wetz, Michael S.
Abstract:: Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...

Personal, interpersonal and infant characteristics as predictors of marital satisfaction during the transition to parenthood

Creator:: Tomlinson, Patricia Short
Abstract:: Ninety-six couples were studied during the transition to parenthood in order to assess a) relative contributions of equity and traditionality in sex role attitudes to marital satisfaction prior to parenthood, b) changes in marital satisfaction and equity after the birth of the infant and c) contributions of traditionality, equity, father...
