Activity of marine bacteria under incubated and in situ conditions

Creator:: Sherr, Evelyn, Sherr, Barry F., and Sigmon, Crystal T.
Abstract:: We evaluated the extent to which the average metabolic activity of open ocean bacterioplankton changed during 2 to 3 d incubations of 1 μm filtered seawater at in situ temperature. Indices of bacterial activity during incubation experiments were compared to those of in situ bacterioplankton, which were repeatedly sampled at...

Cryopreservation of in vitro-grown apical meristems

Creator:: Chang, Yongjian
Abstract:: Alternating temperature (22°C / -1°C) pretreatments were effective for increasing cold hardiness and recovery of cryopreserved meristems. Combining low temperature pretreatment with abscisic acid (ABA) or sucrose treatments reduced the time required for optimal cold hardiness of meristems. Desiccation tolerance was directly correlated with increased cold hardiness and recovery of...

Evaporative heat loss of the upper Middle Fork of the John Day River, northeastern Oregon

Creator:: Benner, David A.
Abstract:: Evaporation was studied along the Middle Fork of the John Day River in northeastern Oregon. Evaporation pans and various meteorological sensors recorded data at nine sites during the summer of 1998; measurements were made at each site over a 3-4 day period. A Dalton-type evaporation model was produced using water...

Susceptibility of riparian soil invertebrates to the herbicide triclopyr

Creator:: Moran, Patrick (Patrick William)
Abstract:: Riparian zones of Pacific Northwest forests have high species diversity and abundance and act as an important interface between the aquatic and terrestrial ecosystems. In addition, riparian zones comprise a significant portion of the total buffer zone established during commercial forest production to protect aquatic ecosystems from adjacent management activities....

Applied and basic aspects of sulfite metabolism in Saccharomyces cerevisiae

Creator:: Park, Hoon
Abstract:: In an effort to understand the basis for sulfite detoxification in S. cerevisiae, the functions of two genes were analyzed. SSU1, which encodes a plasma membrane protein, was found to be required for efficient sulfite efflux. FZFl-4, a dominant allele of a transcriptional activator of SSUl, was also found to...

Optimizing virus detection in potato breeding populations

Creator:: Hane, Dan C.
Abstract:: Virus contamination in a potato breeding program can seriously disrupt the variety development process. Experiments were conducted from 1989 through 1993 to: evaluate the extent to which Potato Leafroll Virus (PLRV) and Potato Virus Y (PVY) can invade a breeding program, determine viral spread within hills and within individual tubers,...

Watershed councils and woodland owners : the Oregon experience

Creator:: Rickenbach, Mark G., 1968-
Abstract:: Oregon's watershed councils are local, non-regulatory, collaborative forums charged with the recovery of endangered salmon and improving water quality under The Oregon Plan for Salmon and Watersheds. Private forest landowners, given their prominence is owning riparian areas, are central to success of these efforts. Using a statewide survey of watershed...

MCNP benchmarking and analysis of Oregon State University TRIGA Reactor

Creator:: Merritt, Patrick A.
Resource Type:: Masters Thesis

Multithreaded virtual processor on DSM

Creator:: An, Ho Seok
Abstract:: Modern superscalar processors exploit instruction-level parallelism (ILP) by issuing multiple instructions in a single cycle because of increasing demand for higher performance in computing. However, stalls due to cache misses severely degrade the performance by disturbing the exploitation of ILP. Multiprocessors also greatly exacerbate the memory latency problem. In SMPs,...

Management of stockpiled forages and optimal use of supplements by beef cattle while consuming low-quality forages

Creator:: Suverly, Norman A.
Abstract:: Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...
