Employed mothers' satisfaction with child care choices : perceptions of accessibility, affordability, quality, and workplace flexibility

Creator:: Elliot, Janis Sabin
Abstract:: Interest in child care has grown dramatically, yet little is known about how families manage to ensure appropriate child care. In a secondary analysis of data from 642 employed mothers representing a wide range of income levels, this research identified the factors contributing most to mothers' satisfaction with child care...

Mycorrhizal and other root endophytic fungi of lupines in the Pacific Northwest

Creator:: O'Dell, Thomas E.
Abstract:: We investigated the root endophytic fungi of lupine using four approaches: (1) occurrence of fungal colonization in field-collected roots; (2) growth response of L. latifolius to inoculation with two types of fungi; (3) structure of root colonizations of Pinus and Lupinus by Phialocephala fortinii, a septate endophytic fungus of lupine;...

Geometric reasoning in an active-engagement upper-division E&M classroom

Creator:: Cerny, Leonard Thomas
Abstract:: A combination of theoretical perspectives is used to create a rich description of student reasoning when facing a highly-geometric electricity and magnetism problem in an upper-division active-engagement physics classroom at Oregon State University. Geometric reasoning as students encounter problem situations ranging from familiar to novel is described using van Zee...

Studies on the glutathione dependent protection of the cell nucleus against lipid peroxidation

Creator:: Tirmenstein, Mark A.
Abstract:: Lipid peroxidation is believed to be an important process in the development of cellular injury. In addition to the degradation of biological membranes, increasing evidence indicates that lipid peroxidation can alter the structure and function of DMA. The present study examines the peroxidation of nuclear membranes and the capacity of...

Performance of perennial ryegrass (Lolium perenne L.) seed crops under water stress conditions

Creator:: Velloza, Theodosius Marmaduke
Abstract:: Summer drought is a major factor limiting the regrowth of perennial ryegrass seed crops. This phase of crop development has a strong influence on seed yield because most of the tillers that contribute towards next season's seed crop are produced or regrown during this period. In recent years many seed...

Vitamin E and the alpha-tocopherol transfer protein during zebrafish embryogenesis

Creator:: Miller, Galen W.
Abstract:: Vitamin E was first described in 1922 as an unknown factor required for impregnated rats to carry their offspring to term. In fact, when vitamin E was chemically characterized it was given the name "tocopherol" derived from the Greek: tokos = childbirth; phero = to bear; and –ol, indicating an...

Vitamin E and K interactions : investigating mechanisms of reduced vitamin K status in response to excess vitamin E

Creator:: Farley, Sherry Mae
Abstract:: The primary goal of my studies was to elucidate the mechanisms for the well-recognized interaction between two nutrients, vitamins E and K. The outcomes from my studies assess mechanisms for adverse effects of vitamin E and provide novel information on mechanisms for vitamin K homeostasis. These findings will provide information...

Energetics and mechanics of swing phase during terrestrial locomotion

Creator:: Nelson, Frank E.
Abstract:: Previous attempts to understand the factors affecting the energetic cost of locomotion have found a direct link between the energetic cost and the mechanical work done during periods when the limb is in contact with the ground. However, when the limb is not in contact with the ground during the...

The effects of selected feeding programs on the reproductive performance and specific blood plasma chemistries of caged broiler breeder males and dwarf breeder females

Creator:: Buckner, Robert E.
Abstract:: I. THE EFFECT OF FEEDING PROGRAMS ON REPRODUCTIVE TRAITS AND SELECTED BLOOD CHEMISTRIES OF CAGED BROILER BREEDER MALES: 1. FEED RESTRICTION LEVELS: The effects of five different feeding levels (136, 125, 113, 102, and 91 g/male/day of a 13.1% crude protein (CP), 3167 kcal ME/kg feed) on the reproductive traits...
