Biological and morphological studies of the Scaphytopius acutus complex (Homoptera:Cicadellidae)

Creator:: Musgrave, Carol A.
Abstract:: Reinterpretation of the leafhopper tribe Scaphytopiini reveals it to be primarily a New World taxon with only limited representation in the Palearctic, Oriental and possibly Ethiopian regions. Approximately 75 species assigned to three genera are known from the United States and Canada with at least another 75 species representing an...

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...

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...

Sticker stain in one-inch red alder lumber

Creator:: Anderson, B. G., Frashour, R. G., and Oregon Forest Products Laboratory
Abstract:: The Oregon Forest Products Laboratory was asked in July 1953 by the Oregon Alder and Maple Company, Willamina, to work on the problem of dark stain which developed at sticker crossings in air-drying red alder (Alnus rubra, Bong.) during the summer months. Previous experience at the Oregon Alder and Maple...

Kiln-drying Oregon maple paper roll plugs

Creator:: Anderson, B. G., Williams, W., Jr., and Oregon Forest Products Laboratory
Abstract:: Four charges of S-inch paper roll plugs of Oregon maple were kiln-dried at various temperatures and humidities. The charge with the most desirable combination of short drying time and low degrade was dried to 12 per cent moisture content in lit hours, using a dry-bulb temperature of 160 degrees F...

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...

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...
