Biaxial strength characteristics of wood-based structural panels were evaluated by
using analytical and experimental methods. Cruciform plywood specimens were tested
under biaxial tensile-tensile, compressive-compressive loadings in a symmetrically-jointed-
arm test fixture, which was mounted on a universal testing machine. Performance
of the test fixture was also evaluated during the tests....

The degradation of kraft pulping wastes in estuarine waters
was measured in terms of the following parameters: five-day 20°C
B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel
(Mytilus edulis L.). The waste tested was the total effluent from a
combined pulp and paper mill producing 430 tons of...
The forest-products industries are most important to the state of Oregon. Oregon leads the nation in the production of plywood, lumber, and particle board. More than half of softwood plywood production in the United States came from Oregon at the time of this survey, and more than a fifth of...
Tanoak lumber might supplement the supply of white oak for boat construction, as the tree has extremely thick sapwood that can be pressure- treated readily with preservatives.
One-inch tanoak lumber was kiln -dried to 3 different moisture content ranges, then pressure -treated with water -borne preservatives. Some unseasoned lumber was...
Machine vision is widely used in scientific areas and non-wood using
industries, but the extreme variability of wood has limited its adoption by forest
products industries. However, it is now becoming a key factor in further automation
of the forest products industry. As a very important part of machine vision,...
This study seeks to determine the feasibility of
utilizing one vaporizable copper compound - bis-[1-
(dimethylamino)-2-propanolato] copper(II) (Cu(DMAP)₂ as a
potential wood preservative. The synthesis of Cu(DMAP)₂
was conducted in accordance with a method developed by
Buhro and Dingman, Washington University, St. Louis,
Missouri. The yields of Cu(DMAP)₂ synthesis were...
Plywood panels collected from thirty seven mills located
throughout the Pacific Northwest they were treated with chromated copper
arsenate Type C (CCA-C) or ammoniacal copper zinc arsenate (ACZA) using
modified full cell and full cell processes respectively. Preliminary
tests were performed to determine plywood sample size, replication, and
treating schedule....
This paper seeks to answer whether problems in intercultural communication
contribute to difficulties in wood products trade between the United States and Japan. It
summarizes the more commonly heard complaints about the current state of this trade
flow, including trade barriers and product specifications. It then offers a list of...
Oregon's forest product industry continues to be the nation's number one
producer of wood products. The forest products industry contributes significantly
to Oregon's economy. Changes in timber supply, land use policy, technology,
and product demand create significant impacts on the region. The activities of
the wood products industry translate into...
