Early spring nutrient conditions of southeastern Alaska's Inside Passage

Creator:: Coughenower, D. Douglas
Abstract:: Observations were made of salinity, temperature, nitrate + nitrite, phosphate, silicate, total available nitrogen, and chlorophyll a in nine areas of the Alaskan Inside Passage during April of 1971. In general all properties indicated the water to be well mixed throughout this area. The conservative properties were particularly uniform. The...

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...

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...

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...

Vapor drying of western woods

Creator:: Graham, R. D. (Robert D.) and Oregon Forest Products Laboratory
Abstract:: The vapor-drying process is described briefly and its present status in industry is discussed. Fairly extensive data on the vapor drying of 1-, 2-, and 4-inch Douglas-fir and 2-inch western hemlock lumber are presented. Exploratory work on the vapor drying of redwood, Pacific madrone, red alder and ponderosa pine is...

Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

Creator:: Ye, T. Z. and Jayawickrama, K. J. S.
Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

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...
