In-forest log segregation based on acoustic measurement of wood stiffness

Creator:: Amishev, Dzhamal Y.
Abstract:: To remain competitive, the forest products industry needs to look for new and innovative processes and technologies to not only reduce costs but also to recover more value through the entire seedling-to-customer forest products supply chain. It is well recognized that measuring wood properties of logs in real time during...

Environmental effects on heartwood extractive content and their consequences for natural durability in Douglas-fir and western redcedar

Creator:: Taylor, Adam McVaugh, 1969-
Abstract:: Heartwood can have properties that are distinct from sapwood, including resistance to insect and microbial attack. Despite the practical importance of heartwood formation in trees, a review of the literature revealed that little was known about the effects of environmental factors on heartwood quality or how variations in heartwood properties...

A model for simulation of subsurface transport of highway-related water quality constituents

Creator:: Hesse, Edwin Todd
Abstract:: A spreadsheet-based transport model was developed in Microsoft Excel™ as part of a six-year National Cooperative Highway Research Program project conducted at Oregon State University. The model simulated the leaching, transport, removal, and retardation processes that occur in the surface and subsurface pathways of the near highway environment. For all...

Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

Creator:: Acuna, Mauricio A.
Abstract:: There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

Influence of veneer roughness, lathe check, and annual ring characteristics on glue-bond performance of Douglas-fir plywood

Creator:: DeVallance, David B.
Abstract:: Current lathe technology, smaller diameter logs, smaller core diameters, and the sale of higher grade veneer for use in engineered wood products are all factors contributing to plywood manufacturers using rougher veneer with different lathe check characteristics. When rough veneer is encountered, plywood manufacturers typically increase the adhesive spread rate...

Using Acoustic Measurements and Inventory Data to Estimate Stiffness in Standing Douglas-Fir Trees

Creator:: Delgado Trejo, Jorge Luis
Abstract:: Total US lumber production in 2011 was 77.9 million cubic meters. Its primary use was for housing and construction. There is a growing concern that the structural properties for wood are being reduced as trees are harvested at much younger ages as the wood supply shifts from older to younger...

Competitive interactions in young, coastal Douglas-fir/red alder mixtures : implications for wood quality

Creator:: Grotta, Amy T.
Abstract:: When Douglas-fir and red alder grow in mixture, interactions between the two species can be competitive, facilitative, or a combination of both over time. A number of factors have recently led to increased interest in managing these two species together for commercial production, and ongoing investigations are yielding important information...

Water quality of runoff from flood irrigated pasture in the Klamath Basin, Oregon

Creator:: Ciotti, Damion C.
Abstract:: Runoff from agricultural lands into Upper Klamath Basin rivers and lakes can cause water quality problems affecting fish and wildlife. Excessive eutrophication in Upper Klamath Lake is linked to high nutrient input (particularly phosphorus) stemming from both lake sediments and watershed tributaries. On a unit area load basis the Wood...

Development of novel analytical methods to detect emerging contaminants in aqueous environmental matrices using large-volume injection

Creator:: Backe, Will J.
Abstract:: It is the responsibility of humans, as environmental stewards, to monitor our impact on the environment so that efforts can be made to remediate the effects of our actions and change behaviors. To better understand our environmental footprint, sensitive and simple analytical methods are needed to quantify the contaminants that...
