Revision of Wyeomyia (Hystatomyia) Dyar & Knab (Diptera: Culicidae: Sabethini

Creator:: Adkins, Jessica Y.
Abstract:: Members of the tribe Sabethini (Diptera: Culicidae) oviposit and develop in phytotelmata (plant-held waters) and are primarily distributed in a pantropical pattern. Recent cladistic studies have demonstrated that while the tribe is monophyletic, three of its 13 genera are not. The genus Wyeomyia is particularly problematic and debate among culicidologists...

Initial study of kiln drying clear Douglas fir planks

Creator:: Stillwell, H. D. and Oregon Forest Products Laboratory
Abstract:: Checking was influenced b drying conditions. This influence was greatest before average moisture content reached 20 per cent, but tension in surface layers caused checking even below this point. Neither high initial dry-bulb temperature nor initial conditions of high equilibrium moisture content were conducive to checking. High temperature and high...

Shrinkage of Douglas fir, western hemlock, and red alder as affected by drying conditions

Creator:: Espenas, Leif D., Oregon State University. Forest Research Laboratory, and Oregon State University. School of Forestry
Abstract:: Moisture content and shrinkage were determined on specimens equilibrated at two conditions for equilibrium moisture content (EMC) at room temperature after the specimens had been dried under a variety of constant temperatures with constant EMC's. Moisture content at room temperature equilibrium was less for specimens dried at high temperature than...

Forced-air drying of lumber in Western Oregon

Creator:: Kozlik, Charles J. and Oregon Forest Research Center
Abstract:: Forced-air drying of lumber is economically feasible as an aid to sawmills without dry kilns. Reduced cost of shipping more than offsets cost of drying with forced circulation of air. Investment in equipment is small. In the Willamette Valley, forced-air drying probably can be accomplished successfully throughout the year. High...

Effect of kiln conditions on the strength of Douglas fir and western hemlock

Creator:: Kozlik, Charles J. and Oregon State University. Forest Research Laboratory
Abstract:: To test the effects of kiln-drying on strength properties of Douglas fir and western hemlock, temperatures to 230 F, conditions for equilibrium moisture contents of 6 percent and 12 percent, and prolonged heating were investigated. Prolonged heating and choice of conditions for 6 percent or 12 percent equilibrium moisture content...

Seasoning and machining degrade in young-growth Douglas-fir dimension lumber

Creator:: Anderson, B. G., Knauss, A. C., Frashour, R. G., and Oregon Forest Products Laboratory
Abstract:: The increasing volume of young-growth Douglas-fir timber cut in the Pacific Northwest emphasizes the need for more knowledge on the characteristics of lumber sawed from these trees. The study described here was initiated to learn the extent arid causes of degrade resulting from kiln-drying young-growth Douglas-fir dimension lumber. At the...
