Crustal inheritance and a top-down control on arc magmatism at Mount St. Helens

Creator:: Bedrosian, Paul A., Peacock, Jared R., Bowles-Martinez, Esteban, Schultz, Adam, and Hill, Graham
Abstract:: In a subduction zone, the volcanic arc marks the location where magma, generated via flux melting in the mantle wedge, migrates through the crust and erupts. While the location of deep magma broadly defines the arc position, here we argue that crustal structures, identified in geophysical data from the Washington...

Sinuous stem growth in a Douglas-fir (Pseudotsuga menziesii) plantation: growth patterns and wood-quality effects

Creator:: Spicer, R., Gartner, Barbara L., and Darbyshire, R. L.
Abstract:: Stem sinuosity is thought to negatively impact wood quality, but no studies have characterized its vertical and radial effects on wood properties. Here we study wood quality along the entire stem in 25-year-old plantation grown Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) trees (32 trees total) that had been scored...

Characterizing the strength of wood truss joints

Creator:: Gupta, Rakesh, Gebremedhin, Kifle G., and Grigoriu, M. D.
Abstract:: Probability density functions (normal, lognormal, and three-parameter Weibull) were used to characterize strength data for three different types of metal-plate-connected wood truss joints (web at the bottom chord, tension splice, and heel). Modulus of elasticity (MOE) of the lumber used to fabricate the joints was also characterized. A probability-plot technique,...

Effect of growth rate on the anatomy, specific gravity, and bending properties of wood from 7-year-old red alder (Alnus rubra)

Creator:: Lei, Hua, Gartner, Barbara L., and Milota, Michael R.
Abstract:: Understanding the association between growth rate and wood properties is of practical importance to maximizing and sustaining wood and fiber production. Anatomical characteristics, specific gravity, and bending properties were determined at breast height for thirty 7-year-old trees with varying growth rates, from a red alder (Alnus rubra Bong.) plantation. Wood...

Innovativeness in the global forest products industry: Exploring new insights

Creator:: Hansen, Eric, Juslin, Heikki, and Knowles, Christopher David
Abstract:: Innovativeness is a concept that has seen extensive study, yet there remain significant gaps in our understanding of the phenomenon. This is especially true when considering views of practitioners as well as specific industry sectors, such as the forest products industry. The qualitative work described here explores the concept of...

Use of through-boring to improve CCA or ACZA treatment of refractory Douglas-fir and grand fir

Creator:: Rhatigan, R. G. and Morrell, J. J.
Abstract:: Large quantities of smaller diameter materials are available in the overstocked forests of eastern Oregon and Washington, but the costs of removing these materials and the long distances from markets sharply reduce the potential of this resource. Failure to thin these forests will sharply increase the likelihood of catastrophic wildfires....

Effect of inspection holes on flexural properties of Douglas-fir utility poles

Creator:: Morrell, Jeffrey J., Sinha, Arijit, Clauson, Milo, and Love, Connie S.
Abstract:: Routine inspection of wood utility poles to detect internal decay involves drilling holes at or about the ground line. While these holes are useful for detecting internal decay, their presence raises concern among engineers about their potential effects on pole flexural properties. The effect of inspection holes on flexural properties...

Preservative treatment of Scots pine and Norway spruce

Creator:: Rhatigan, Ron, Freitag, Camille, El-Kasmi, Silham, and Morrell, Jeffrey J.
Abstract:: The ability to treat Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) with oilborne copper-8-quinolinolate or with waterborne chromated copper arsenate, ammoniacal copper zinc arsenate, or ammoniacal copper quaternary was assessed using commercial treatment facilities in the Pacific Northwest. In general, Scots pine was more easily treated than was...

Effect of high temperature drying on permeability and treatment of western hemlock lumber

Creator:: Rhatigan, Ronald G., Milota, Michael R., Morrell, Jeffrey J., 1955-, and Lavery, Mark R.
Abstract:: The effect of drying conditions on gas permeability and preservative treatability was assessed on western hemlock lumber. Although there were no differences in gas permeability between lumber dried at conventional and high temperatures, there were differences in preservative penetration. High-temperature drying was associated with improved penetration of ammoniacal copper zinc...

Effect of Initial Preservative Treatment on Electrical Conductivity in Douglas-Fir Pole Sections

Creator:: Jeffrey J. Morrell, Milo Clauson, and Connie S. Love
Abstract:: The effect of copper naphthenate treatment on electrical resistance of Douglas-fir utility poles was compared with similar poles either left untreated or treated with pentachlorophenol (penta). Penta-treated and untreated wood had similar electrical resistance shortly after treatment and after a 3-month outdoor weathering period. Electrical resistance of copper naphthenate– treated...
