We conducted a combination road/plot impact survey for dwarf mistletoe in lodgepole pine on six East Side National Forests in 1978. The road survey showed infestation percentages ranging from 28.2 on the Custer to 52.4 on the Beaverhead. The plot survey showed annual cubic foot volume losses ranging from 106M...
Relaxor characteristic of the solid solution (1-x)BaTiO₃-(x)Bi(Zn₁/₂Ti₁/₂)O₃ (BTBZT) was investigated in this research. X-ray diffraction technique and Raman spectroscopy revealed the crystal structure of BT-BZT at various compositions. For compositions with x ≤ 0.08, the solid solutions exhibited clear tetragonal symmetry and transitioned to pseudo-cubic symmetry as the content of...
Wild-caught juvenile Steller sea lions Eumetopias jubatus (n = 21) were maintained in temporary captivity for up to 12 wk to investigate health, disease, nutrition and behavior. We assessed the effects of captivity on post-release dive behavior and movement of each animal using externally mounted satellite data recorders. Based on...
Best available copy. In 1984, longstanding concerns about pollution in Yaquina Bay impelled the U.S. Food and Drug Administration to make a comprehensive sanitary survey of the Yaquina River, with particular emphasis on areas where oysters were grown. The report states that the oyster plots endured "sporadic poor water quality,"...
The purpose of the study was to develop a system and procedure for classifying and cataloguing the textile, costume, and slide collections of the Clothing, Textile, and Related Arts (CTRA) Department at Oregon State University. Investigation was made by letter, personal visit, interview with faculty and curators, and literature research...

The influence of substrate and enzyme concentration on the rate
of saccharification of two defined, insoluble, cellulose substrates,
Avicel and Solka-Floc, by the cellulase enzyme system of Trichoderma
viride has been evaluated. Assays utilized enzyme concentrations
ranging from 0.014 to 0.056 filter paper unit per mL and substrate
concentrations up...
