Wood quality studies in second-growth western redcedar (Thuja plicata Donn.)

Creator:: DeBell, Jeffrey D.
Abstract:: Western redcedar (Thuja plicata Donn.) is a valuable commercial species found in the northwestern United States and southwestern Canada. This dissertation includes four papers focused on wood and stem characteristics of second-growth western redcedar, and how those characteristics vary within the stem or how they are influenced by cultural practices....

Municipal water source turbidities following timber harvest and road construction in western Oregon

Creator:: Grizzel, Jeffrey D.
Abstract:: Many municipalities throughout western Oregon rely upon forested watersheds as a source for domestic water supply. These watersheds are commonly managed by state or federal agencies or private corporations for timber production. Activities related to forest management within municipal watersheds have the potential to adversely affect water quality. Timber harvesting...

Tropolone content of increment cores as an indicator of decay resistance in western redcedar

Creator:: DeBell, Jeffrey D., Morrell, Jeffrey J., and Gartner, Barbara L.
Abstract:: The high decay resistance of western redcedar (Thuja plicata Donn) is due to the presence of toxic extractives, called tropolones, in the heartwood. Therefore, tropolone content may be used as an indicator of decay resistance. With increment core-sized samples of western redcedar heartwood, we used gas chromatography to measure tropolone...

Interactions between sodium N-methyldithiocarbamate and Douglas-fir heartwood

Creator:: Miller, D. B. and Morrell, Jeffrey J.
Abstract:: Vapam(r) (NaMDC) is the fumigant most commonly used to arrest and control decay of utility poles. While volatile fungitoxins are detectable only 1 to 2 years after treatment, poles treated with Vapam(r) remain free of decay fungi for 6 to 17 years. Vapam(r) decomposes to produce volatile fungicides as well...

Transport timescales in the Martian atmosphere: General circulation model simulations

Creator:: Barnes, Jeffrey R., Walsh, Thomas D., and Murphy, James R.
Abstract:: Simulations with a Mars general circulation model (GCM) are used to perform idealized tracer transport experiments, which are analyzed to yield estimates of eddy mixing coefficients as well as “stratospheric” ventilation timescales for the zonal-mean circulation. The results indicate that relatively moderate values of the vertical eddy mixing coefficient, KZ...

Fiber length in young hybrid Populus stems grown at extremely different rates

Creator:: DeBell, Jeffrey D., Gartner, Barbara L., and DeBell, Dean S.
Abstract:: Length of libriform fibers was measured in rings 2 7 at breast height in 7-year-old hybrid poplar stems from two clones (11-11, a Populus trichocarpa Torr. & Gray ´ P. deltoides Bartr. ex Marsh. hybrid; and D-01, of unknown taxonomic identity) grown in a controlled test of three spacings (0.5,...

Naturally Occurring Thiamine Deficiency Causing Reproductive Failure in Finger Lakes Atlantic Salmon and Great Lakes Lake Trout

Creator:: Fisher, Jeffrey P., Fitzsimons, John D., Combs, Gerald F. Jr., and Spitsbergen, Jan M.
Abstract:: A maternally transmitted, noninfectious disease known as the Cayuga syndrome caused 100% mortality in larval offspring of wild-caught landlocked Atlantic salmon Salmo salar from several of New York's Finger Lakes. Survival of lake trout Salvelinus namaycush from Lakes Erie and Ontario was also impaired, but not until yolk absorption was...

The atmosphere structure and meteorology instrument on the Mars Pathfinder lander

Creator:: Seiff, Alvin, Tillman, James E., Murphy, James R., Schofield, John T., Crisp, David, Barnes, Jeffrey R., LaBaw, Clayton, Mahoney, Colin, Mihalov, John D., Wilson, Gregory R., and Haberle, Robert M.
Abstract:: An instrument on the Pathfinder lander has been designed to measure the structure of Mars’ atmosphere during spacecraft entry and descent from ~150 km altitude to the surface, and to measure meteorological parameters after landing for the landed duration of the mission. This is specified to be nominally 30 Mars...

Overview of the mars pathfinder mission : launch through landing, surface operations, data sheets, and science results

Creator:: Golombek, M. P., Anderson, R. C., Barnes, Jeffrey R., Bell III, J. R., Bridges, N. T., Britt, D. T., Brückner, J., Cook, R. A., Crisp, J. A., Economou, T., Folkner, W. M., Greely, R., Haberle, R. M., Hargraves, R. B., Harris, J. A., Haldemann, A. F. C., Herkenhoff, K. E., Hviid, S. F., Jaumann, R., Johnson, J. R., Kallemeyn, P. H., Keller, H. U., Kirk, R.

W., Tomasko, M. G., Vaughn, R. M., Wänke, H., and Wilson, G. R.
Abstract:: Mars Pathfinder successfully landed at Ares Vallis on July 4, 1997, deployed and navigated a small rover about l00 m clockwise around the lander, and collected data from three science instruments and ten technology experiments. The mission operated for three months and returned 2.3 Gbits of data, including over 16,500...
