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...

An evaluation of the use of tarif tables in second growth Douglas-fir

Creator:: Marshall, David D.
Abstract:: The Washington State Department of Natural Resources' Comprehensive Tree-Volume Tarif Tables are a set of preconstructed local volume tables. This can increase "on plot" efficiency since only diameters are necessary to obtain volumes after the proper table for the given diameter/height relationship is accessed. The tables are accessed and indexed...

Discrete compression web bracing design for light-frame wood trusses

Creator:: Waltz, Miles E.
Abstract:: As part of a roof framing system, light-frame wood trusses often require lateral bracing to reduce the effective length for flexural buckling of compression web members. This observational research investigates the design requirements for discrete compression web bracing intended to provide such lateral support. Four simple brace analysis methods based...

Hungry Bob Harvest Production Study : mechanical thinning for fuel reduction in the Blue Mountains of northeast Oregon

Creator:: Coulter, Elizabeth Dodson
Abstract:: Fire exclusion in the western U.S.A. has caused fuel loads to build up and overall forest health to decline. Managers are now looking for ways to reduce these fuel loads while reintroducing some of the desired effects of natural wildfire. One method to do this is thinning using mechanical harvesting...

An econometric model of hardwood lumber and stumpage markets in the United States

Creator:: Lange, William J.
Abstract:: Two econometric models were developed to forecast consumption, production, and price of hardwood lumber, and removals and price of hardwood sawlog stumpage. Four eastern U.S. regions were represented in the models. Hardwood lumber consumption by manufacturing, shipping, residential construction, and nonresidential construction industries was recognized. Hardwood sawlog stumpage removals from...

The valuation and use of site information for Douglas-fir reforestation in Western Oregon : a decision analysis

Creator:: Schöne, Dieter Hans-Friedrich
Abstract:: Existing forest site maps have been described as "invaluable tools" in forest management. Their, economic value potentially materializes as the summed advantage from better decisions in all phases of forestry. Via Bayesian decision analysis, this study establishes optimal use and economic value of site information for one facet of management...

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...

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....
