Castle Rocks : a late miocene eruptive center at the north end of Green Ridge, Jefferson County, Oregon

Creator:: Wendland, David W.
Abstract:: Castle Rocks is 12 miles east of Mt. Jefferson, in the central Cascades of Oregon. The area contains volcanic rocks ranging from mid-Miocene to Holocene in age. These rocks record alternating periods of tholeiitic and calc-alkaline volcanism. The oldest rocks in the area range from basaltic andesite lava flows to...

Exogenous and endogenous factors related to seed germination and vigor in certain varieties of sugarbeet Beta vulgaris L.

Creator:: Kim, Syng Chul
Abstract:: Studies were conducted on the causes of low germination of monogerm sugarbeet seed grown in western Oregon. Emphasis was placed on the identification and measurement of endogenous inhibitors as related to the germination and vigor. Both qualitative and quantitative analytical methods were applied to examine the organic substances in the...

Holocene sediments of the South Atlantic Ocean : the calcite compensation depth and concentrations of calcite, opal and quartz

Creator:: Ellis, David Burl
Abstract:: The concentrations of calcite, opal and quartz have been measured in 113 South Atlantic core tops. The remainder of the total sample has been calculated as clay. A method for the quantitative determination of opal has been developed. Calcite is the dominant factor in South Atlantic sediments; its pattern can...

Substitution of germanium for boron in suspension-cultured carrot cells

Creator:: Durst, Robert W.
Abstract:: Boron has been recognized since 1923 as an essential micronutrient for vascular plants, but its function is still not known. Many diverse roles have been proposed, but none of these has been definitively shown. Problems that have made the study of the function of boron difficult include, no useful radioisotope,...

Development of tree height and diameter growth equations for mid-Willamette Valley Douglas-fir

Creator:: Ritchie, Martin W.
Abstract:: Equations for predicting height growth, basal area growth and diameter inside bark are presented for Douglas-fir. Basal area growth equations for grand fir are also presented. The growth models were developed for use in an individual tree/distance independent growth simulator. Various model forms and measures of competitive stress were compared...

Historical analysis of dental hygiene independent practice and its prospective future : 1965 to present

Creator:: Smith, Judith Claire
Abstract:: This research project historically reviews literature relating to dental hygiene practice, more specifically dental hygiene independent practice movements. From the early days of dental hygiene to current legislative actions, material applicable to dental hygienists practicing independently is presented. Information relating to the public's perception of this field, dental hygiene's professional...

Evaluation of perennial ryegrass straw as a forage source for ruminants

Creator:: Fisher, Michael J.
Abstract:: We conducted two experiments evaluating perennial ryegrass straw as a forage source for ruminants. Experiment 1 evaluated digestion and physiological variables in steers offered perennial ryegrass straw containing increasing levels of lolitrem B. Sixteen ruminally cannulated Angus X Hereford steers (231 ± 2 kg BW) were blocked by weight and...

Purification and identification of a 100 kDa protein, which is tyrosine-phosphorylated by EGF stimulation in SFME cell

Creator:: Murayama, Kaoru
Abstract:: Serum-free mouse embryo (SFME) cells, which were derived from 16-day-old Balb/c mouse embryo brain, grow in absence of serum without losing genomic normality or proliferative potential, and require epidermal growth factor (EGF) for normal growth. EGF is a well studied mitogen that binds to a specific receptor on the cell...

Isozyme banding patterns and embryo development in interspecific crosses of Phaseolus

Creator:: Guo, Mei
Abstract:: Interspecific hybridization between Phaseolus vulgaris and P. coccineus results in the formation of either mature F₁ seeds or abnormal embryos, depending on the direction of the cross. However, normal as well as abnormal embryos occur in the reciprocal F₂ populations. The exact cause of abnormal embryo development is unknown. To...
