Creator:: Przybylowicz, Paul
Abstract:: Influence of temperature and wood moisture content on spore germination and colonization of Douglas-fir (Pseudotsuga jnenziesii) heartwood by Poria carbonica basidiospores and chlamydospores was studied. Both spore types germinated and colonized wood at moisture contents above the fiber saturation point, but not below. Germination and wood colonization occurred at 22°C...

Creator:: Forrer, Johannes B.
Abstract:: Raw material costs and limited material availability and quality have created significant interest in and opportunities for the application of nondestructive evaluation techniques to improve wood processing technologies. The incentives come from the desire to 1) manufacture the highest valued product, 2) conserve the amount of raw material used, 3)...

Full Text:: DOUBLE RESONANT TECHNIQUE FOR THE MEASUREMENT OF DIELECTRIC PROPERTIES OF WOOD 127 Appendix 2 DIELECTRIC

Creator:: Schneider, Philip F.
Abstract:: Two approaches to improving wood treatability include the modification of pressure schedules during conventional liquid treatments and the use of supercritical fluids (SCFs). In both of these techniques, pressure differences are important for transporting materials into wood. The level of pressure and its change during SCF treatments are also important...

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...

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...
