The effect of light intensity on Douglas-fir foliage quality : survival and development of Western spruce budworm

Creator:: Waddell, Karen L.
Abstract:: Foliage from Douglas-fir(var. glauca) seedlings grown under two light intensities was bioassayed to examine palatability to the western spruce budworm (Choristoneura occidentalis Free.). Samples were collected in Fall, Winter and early Spring to identify seasonal changes in host foliage, as evidenced by the response of spruce budworms. Fall collected foliage...

Cell cycle regulation of DNA precursor accumulation in the yeast Saccharomyces cerevisiae

Creator:: Koc, Ahmet
Abstract:: In budding yeast, many of the genes that encode enzymes required for DNA precursor synthesis (MCB genes) are expressed under cell cycle control in late G1/S. The relationship between MCB gene expression, dNTP synthesis and DNA synthesis was investigated by using α factor-synchronized Saccharomyces cerevisiae. The levels of all four...

Placement of felled western juniper trees over a stream channel : Effects on water temperature, streamside willow shrubs, and redband trout

Creator:: Matney, Casey A.
Abstract:: All streams in Oregon that are inhabited by salmon and trout have a statemandated water temperature standard. However, temperatures of many streams, especially during summer months, exceed the seven-day average maximum temperature parameter (200 C for redband trout inhabited streams) accepted by the Oregon Department of Environmental Quality. To date,...

Solving polynomial equations from 2000 B.C. through 20th century

Creator:: Farea, Hussain A.
Abstract:: This paper is divided into two parts. The first part traces (in details providing proofs and examples) the history of the solutions of polynomial equations(of the first, second, third, and fourth degree) by radicals from Babylonian times (2000 B.C.) through 20th century. Also it is shown that there is no...
