Welcome to Unit II of Wood Science, THE WONDERFUL WORLD OF WOOD!
This is the second in the series of 4-H Wood Science manuals. If you have completed Wood Science I, you probably are asking, “Now what?” Wood Science can be so interesting and challenging that you never really finish....
The authors of this paper met at a summer institute sponsored by the Oregon Collaborative for Excellence in the Preparation of Teachers (OCEPT). Edwards is a researcher in undergraduate mathematics education. Ward, a pure mathematician teaching at an undergraduate institution, had had little exposure to mathematics education research prior to...
Disease transmission forecasts can help minimize
human and domestic animal health risks by indicating
where disease control and prevention efforts should be
focused. For disease systems in which weather-related
variables affect pathogen proliferation, dispersal, or transmission,
the potential for disease forecasting exists. We
present a seasonal forecast of St. Louis...
This annotated bibliography was prepared for the Salmon Anchor Habitat Work Group. This group was formed by the Oregon Department of Forestry to review and evaluate the Salmon Anchor Habitat Strategy as directed by the 2003 Oregon Legislature. The Salmon Anchor Habitat Strategy is a component of management plans developed...
Once lost, a species can never be recovered, and there is no way of knowing how useful it may have been. We do know that human beings and many of their industries depend on plant and animal products. About 50% of all pharmaceuticals have a natural component as an active...
Previous laboratory and field studies have presented evidence for the existence of limestone ecotypes in white spruce (Picea glauca (Moench) Voss). Remeasurements of the range-wide 410 series of provenance trials were used for further evaluation of the existence of these ecotypes. In 2001, heights were measured of 23 provenances grown...
Observations of turbulence, internal waves, and subinertial flow were made over a steep, corrugated continental slope off Virginia during May–June 1998. At semidiurnal frequencies, a convergence of low-mode, onshore energy flux is approximately balanced by a divergence of high-wavenumber offshore energy flux. This conversion occurs in a region where the...
Multicellular eukaryotes produce small RNA molecules (approximately 21–24 nucleotides) of two general types, microRNA (miRNA) and short interfering RNA (siRNA). They collectively function as sequence-specific guides to silence or regulate genes, transposons, and viruses and to modify chromatin and genome structure. Formation or activity of small RNAs requires factors belonging...
