Responses of five genotypes of Agrostis L. to variations in environment

Creator:: Vaartnou, Herman
Abstract:: Morphological changes in five clonally propagated genotypes of Agrostis L. resulting from variations in environment were studied in six natural environments extending from southern Oregon to northern British Columbia. These same clones were also subjected to four different cutting heights in turf plots. In addition to the field experiments, they...

The Roles of Dietary Nitrate in Bone and the Gut in an Ovarian Hormone-deficient Rodent Model

Creator:: Conley, Melissa N.
Abstract:: Osteoporosis is a common metabolic bone disease, affecting a third of women and a fifth of men over age 65. In the US, annual health care costs associated with osteoporosis are estimated to be over $20 billion. Osteoporosis is associated with increased fracture risk, which has been demonstrated to predict...

Characteristics of two noncarotenogenic light sensitive mutants of Scenedesmus obliquus strain D₃

Creator:: Harvey, Geoffrey W.
Abstract:: Two light sensitive mutants of the green alga Scenedesmus obliquus strain D₃ have been characterized. The photodynamic nature of their sensitivity has been established, the subchloroplast site of photodamage has been investigated, and their noncarotenogenic character has been verified. The two mutants possess several similarities, although mutant L. S. -41...

Life history and production studies of Sialis californica Banks and Sialis rotunda Banks (Megaloptera : Sialidae)

Creator:: Azam, Khaja Mohammed
Abstract:: Comparative ecological studies of Sialis californica Banks and Sialis rotunda Banks were made in Western Oregon from 1966 to 1968. Field collections for S. rotunda were made in fish holding pond at the Oak Creek laboratories, 5 miles west of Corvallis, Benton County, and for S. californica in enriched sections...

The effects of a mutation within vitamin E biosynthesis upon the development and function of the photosynthetic apparatus

Creator:: Sicher, Richard Charles
Abstract:: A new photosystem-II mutant of the green alga Scenedesmus obliquus D₃, strain PS-28, has been shown to lack a-tocopherol (vitamin E). The photosynthetic activity of dark grown samples of PS-28 is about 20% of the wild-type control. Culturing the mutant at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic activity...

Effect of organic residue and nitrogen levels on growth of spring wheat and ryegrass

Creator:: Panchaban, Santibhab
Abstract:: The vast area of sandy soils in Thailand which are low in fertility and can hardly hold water, prompted this investigation. A greenhouse study was conducted from December 1978 to April 1980 to find out the effect of straw on nitrogen availability that could affect dry matter yield and nitrogen...

An examination of students' attitudes toward school and classroom science

Creator:: Morrell, Patricia Drozdowski
Abstract:: The purpose of this study was to examine fifth, seventh, and tenth graders' attitudes toward school and classroom science by means of questionnaires and interviews. In particular, the study hoped to determine (a) if a relationship existed between these two attitudes, (b) what relationship, if any, grade level, gender, ethnicity,...
