X-ray structure studies of oriented phospholipid multilayers

Creator:: Lytz, Robert Keith
Abstract:: Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...

William Keith Brooks (1848-1908) : a case study in morphology and the development of American biology

Creator:: Benson, Keith Rodney
Abstract:: The major historical studies that have examined American biology have emphasized the development of experimental biology at the end of the nineteenth century. In this characterization, the descriptive branch of biology has often been treated as less than important and, in several cases, as a hindrance in the application of...

Willamette and associated soils on late Pleistocene geomorphic surfaces, Polk County, Oregon

Creator:: Gelderman, Frederick W.
Abstract:: The morphology and genesis of soils of the Willamette series and of some Willamette-associated soils and their relationships to geomorphic surfaces were studied in an area near McCoy, Polk County, Oregon. Influences of regional extent, such as climate and parent material, were related to the soils and landforms. The soils...

Weather as an influencing factor in the use of Oregon's coastal recreation areas

Creator:: Rense, William Childs, 1944-
Abstract:: The role of weather in influencing tourist-recreation visitation to the Oregon coast during the six-month summer season of May through October has been investigated by this research. In addition, the normal day-to-day fluctuations in coastal visitation has been determined. Based upon the normal visitation, the tourist-recreation season on Oregon's coast...

Water relations and the root regeneration response of Douglas-fir

Creator:: Cobb, Cheryl Anne
Abstract:: The effect of lifting date and root-pruning treatments on water potential, root regeneration, and shoot growth of six-month-old and three-year-old Douglas-fir seedlings bare-root transplanted into a growth chamber, and sawdust bed, respectively, was studied. Root growth in six-month-old and three-year-old seedlings was highest in February and August respectively. Survival was...

Water and anion movement in selected soils of western Oregon

Creator:: Hammermeister, Dale P.
Abstract:: Experiments were carried out to study the movement of water and halide anions in perched water tables or saturated zones in the soil and upper rock mantle of eight different experimental sites located on low hills near the western border of the Willamette Valley. At each site the experimental procedure...

Wasco and Warm Springs Indian clothing for six periods between 1805 and 1976

Creator:: Altseimer-Tilson, Wendy Victoria
Abstract:: The purpose of this study was twofold. One purpose was to investigate the clothing worn by the adult members of the Wasco and Warm Springs Indians. Six periods of time were examined: Period I - 1805-1811 Period II - 1870's-1880's Period III - 1900-1905 Period IV - 1950's-192-0's Period 7...

Vaccination studies with bovine adenovirus type 3 in a dairy calf herd

Creator:: Wangelin, James Richard
Abstract:: In October 1977, a study was undertaken to determine the role of bovine adenovirus type 3 in enzootic pneumonia of calves, and the efficacy of using a vaccine for prevention of disease. Bovine adenovirus type 3 was isolated from the herd under study in the previous year. Calves in the...
