LOGCOST a harvest cost model for southwestern Idaho

Creator:: Giles, Robert Steven
Abstract:: LOCCOST is an interactive computer program that predicts stump to mill logging costs, stumpage and net present value of a harvest based on stand data, pond value and logging parameters, entered by the user. The program is intended for use by foresters to evaluate the economics of different stand management...

Comparative test methods for evaluating shear strength of structural lumber

Creator:: Riyanto, Djoko S.
Abstract:: Five different test methods to determine the parallel-to-grain shear strength of Douglas-fir structural lumber were compared. Four methods assessed the shear strength of lumber sections having a full nominal two by four inch cross-section. These were: three-point bending, four-point bending, five-point bending, and torsion. The fifth method was the ASTM...

Application of polyallylamine as a dry strength agent

Creator:: Rathi, Mahesh Shrikant
Abstract:: Dry strength is an inherent structural property of a paper sheet. It is due primarily to the development of fiber-to-fiber bonds. Polyamines, especially polyallylamine·HC1 (PAA), were found to be suitable mordants for rosin sizing. However, their effectiveness as dry strength agents has not been studied. In this study polyallylamine·HC1 was...

Isolation of protoplasts from selected wood degrading fungi and their uses in studying fungicidal action

Creator:: Chen, Rui, 1963-
Abstract:: Studies of physiological effects of fungicides on fungi are critical for understanding modes of action and mechanism of resistance; however, studies are difficult to perform on filamentous fungi because of the inability to produce homogeneous a biological system using a mass of mycelium. Moreover, the presence of rigid cell wall...

Efficiency of forest vegetation control with herbicides

Creator:: Fredrickson, Edward A.
Abstract:: Selective suppression of crown and root sprouting of non-coniferous cover are the keys to effective forest vegetation management. This study 1) develops insight into mechanisms of controlling root suckering and top regrowth of bear clover (Chamaebatia foliolosa), and develops a broad data base for controlling broad groups of vegetation chemically....

Grant County, Oregon : impacts of changes in log flows on a timber-dependent community

Creator:: Miller, Lester F.
Abstract:: Competitive bid sales of U.S. Forest Service in the Pacific Northwest timber resources have significant effects on the economies of Oregon, Washington, and Idaho. These sales contribute to the economic vitality of small regions or communities dependent upon timber as a primary resource input. Any changes in the price or...

Properties of veneer sliced from serpentine-end-matched flitches

Creator:: Liu, Yuqing
Abstract:: Eighteen Ponderosa Pine (Pinus ponderosa Dougl.ex.laws) veneer flitches were randomly selected and crosscut into paired flitches. Serpentine-end-matched (SEM) joints were machined in the flitches, joint amplitude equal to the width in one half of the paired flitch and joint amplitude equal to 2/3 width in the other half of the...

Applying random utility modeling to recreational fishing in Oregon : effects of forest management alternatives on steelhead production in the Elk River watershed

Creator:: Alexander, Susan J.
Abstract:: A random utility model of trip demand for steelhead fishing is constructed by using a logit regression technique and data from the 1990 Oregon Angler Survey, conducted by the Oregon Department of Fish and Wildlife. The model is formulated to estimate demand when only the regional destination is known. Results...

Development of an Accelerated Method for Assessing Decay of Wood Plastic Composites (WPC's)

Creator:: Silva Guzman, Jose Antonio
Abstract:: This study examined the decay resistance of the pine and maple components of wood plastic composites (WPC' s) of varying thicknesses exposed on several culture media to wood decay fungi under laboratory conditions. The ability of malt agar extract (MEA), potato dextrose agar (PDA), amended basal salts, sawdust (maple and...
