A literature review and a computer study are conducted to identify
the requirements of finite element programs for the specific use of discrete
analyses of reinforced soil structures. The utility of six commercially
available programs are appraised with respect to the identified
requirements. The results of the study are directed...
Temperate nearshore reefs along the Pacific coast of North America are highly valuable to commercial and recreational fisheries yet comprise a small fraction of the seabed. Monitoring fisheries resources in this region is difficult; high-relief structural complexity and adverse sea conditions have led to a paucity of information on temperate...
Leafcutter ants cut trimmings from plants, carry them to their underground nests and cut them into smaller pieces before inoculating them with a fungus that serves as a primary food source for the colony. Cutting is energetically costly, so the amount of cutting is important in understanding foraging energetics. Estimates...
While there has been growing interest in the gut microbiome in recent years, it remains unclear whether closely related species and strains have similar or distinct functional roles and if organisms capable of both aerobic and anaerobic growth do so simultaneously. To investigate these questions, we implemented a high-throughput mass...
Children’s behavioral self-regulation and executive function (EF; including attentional or
cognitive flexibility, working memory, and inhibitory control) are strong predictors of
academic achievement. The present study examined the psychometric properties of a
measure of behavioral self-regulation called the Head-Toes-Knees-Shoulders (HTKS) by
assessing construct validity, including relations to EF measures, and...
Environmental contributions to cancer development are widely accepted, but only a fraction of all pertinent exposures have probably been identified. Traditional toxicological approaches to the problem have largely focused on the effects of individual agents at singular endpoints. As such, they have incompletely addressed both the pro-carcinogenic contributions of environmentally...
These are the proceedings of the fifth short course in managing young forests in the Douglas-fir region, conducted by the School of Forestry, Oregon State University, June 11-13, 1973.
Knowledge and experience in the management of young forests continues to expand. The short courses are designed to keep pace with...
Nitrate concentrations, chlorophyll a (Chl a) fluorescence, radiance, salinity, and
temperature were measured on the Hawaii Air-Sea Logging Experiment, A Long-Term
Oligotrophic Habitat Assessment (HALE ALOHA) mooring located near the Hawaii
Ocean Time-Series (HOT) Program’s Station ALOHA (22°45’N; 158°W). Nitrate
concentrations were determined with OsmoAnalyzers deployed at depths of 120...
These are the proceedings of the third short course in the management of young Douglas-fir and western hemlock conducted by the School of Forestry, Oregon State University, June 15-18, 1970.
The course included one day of lectures and discussion on the campus of Oregon State University, two all-day field trips...
