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...
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...
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....
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...
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,...
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,...
The pigments of blackberry fruit were investigated by analytical and preparative high performance liquid chromatography (HPLC) to characterize anthocyanin patterns in commercially important blackberry (Rubus eubatus) cultivars and selections. Five anthocyanin pigments were detected in Evergreen blackberry and they were identified as cyanidin-3-glucoside, cyanidin-3-rutinoside, pentosecyanidin derivative and two acylated cyanidin...
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...
The increased US domestic production of surimi from the US Pacific Coast after 1977 is a major consequence of the US's extended fisheries jurisdiction to 200 nautical miles. It is only one consequence, however, whose nature can best be understood by examining the surimi market in the context of what...
Streptomycin resistance in both gram-positive and gram-negative bacteria is usually caused by a single mutation in the rpsL gene. The rpsL gene encodes the S12 protein of the ribosomal complex. The rpsL genes of various bacteria have consensus regions in their sequences. Primers were designed from these consensus pockets and...
This research project examines the growing informal sector of Ukrainian economy and the way global economic changes affect women's lives. It has been noticed by many Western researchers that women have been among the hardest hit by economic restructuring in Eastern Europe. Marginalization from the official labor force led a...
The microprocessors will have more than a billion logic transistors on a single chip in the near future. Several alternatives have been suggested for obtaining highest performance with billion-transistor chips. To achieve the highest performance possible, an on-chip multiprocessor will become one promising alternative to the current superscalar microprocessor. It...
State parks in Oregon provide important sites for visitor recreation and natural resource education. With the increasing number of visitors to Oregon coastal parks, tide pools and beach areas, there is growing need for site-specific marine education to enhance stewardship, interpretation and safety knowledge. The Oregon Sea Grant Program and...
Cellular Manufacturing Systems (CMS) have claimed many advantages over traditional job shop processes. Some of the advantages reported by several users of CMS are reduction in throughput time, reduction in WIP inventory, improvement in product quality, faster response time to customer orders, shorter move distances, increase in manufacturing flexibility, and...
The development of winter 6-row malting barley varieties is an objective of the OSU program. The program's winter germplasm is quite susceptible to Barley Yellow Dwarf Virus (BYDV). The program recently released the spring 2-row variety Orca, which carries the Yd2 gene for BYDV resistance. The objective of this project...
The Buraku people have been segregated, oppressed, and discriminated against throughout Japanese history. The Japanese can dismiss the Buraku issue because of assimilation theories, the belief in homogeneity, and passive attitudes by the Buraku people. The Buraku Liberation League (BLL), which has fought for equal rights on behalf of the...
This study describes the experience of homelessness and pregnancy for seven women and their partners in Lane County, Oregon. Homeless pregnant women provide a unique challenge to health care providers and social workers. These women are at increased risk for many negative factors that could affect their pregnancy outcomes. The...
Winter wheat is commonly grown in dryland cropping systems in the Pacific Northwest region of semi-arid eastern Oregon. For agronomic, economic, and environmental reasons, it is important to understand the long-term sustainability of such dryland systems. The objective of this study was to evaluate the long-term effects of tillage, nitrogen...
