Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...
Put generally, the work I have conducted in my time at Oregon State University has been to answer two questions. The first of these is “Why do I get this particular product from this particular chemical reaction?” and the second is “How do the reagents in this chemical reaction lead...
The High Lava Plains province (HLP) of southeastern Oregon is a Miocene to Recent volcanic upland characterized by widespread basaltic volcanism and west-migrating rhyolitic volcanism. New ⁴⁰Ar/³⁹Ar ages for HLP rhyolites demonstrate that the trend of migrating rhyolitic volcanism is robust, reflecting westward migration at a rate of -35 km/m.y....
Eighteen multiparous, high producing (7,836 kg 4%
FCM) Holstein dairy cows were assigned randomly to iso-
.
caloric rations containing either 12 or 23% crude protein
(CP) on day 40 postpartum. After a 10-day adaptation
period, uterine secretion and blood samples were collected
on the day of estrus (day 0-1),...
The glaciated coastal mountain watersheds that drain into the Gulf of Alaska (GOA) provide a model laboratory to explore the challenges of hydrological modeling and study the impact of climate and glacier cover change on regional hydrology. The region is data-sparse and contains a complex assemblage of topography and land...
Large silicic magmatic systems are responsible for producing the largest explosive volcanic eruptions on earth. These phenomena, although infrequent (i.e., 1 per 100,000 years), impact the global climate, deposit ash over continent sized regions, and significantly alter landscapes. Silicic magmatism also plays important roles in the formation and ongoing evolution...
Jordan has a higher fertility rate (3.8) than the averages of countries similar in income to Jordan (2.2) and compared to the Middle East and North Africa region as a whole (2.8) (WHO, WB, UNICEF, & DHS, 2011). The findings of the 2009 Jordanian Population and Family Health Survey demonstrated...
Hybrids with abnormal development were obtained when particular
genotypes of Phaseolus vulgaris L. were crossed. The phenotypic
aberrations of the F₁s included retarded growth, chlorosis of the
trifoliate leaves and the formation of adventitious roots on the
hypocotyls. The expression of the abnormalities was dependent on the
temperature. At high...
