  • The phytosanitation of solid wood packaging materials using wood preservatives

    Creator:
    Schauwecker, Christoph F.
    Abstract:
    New species introductions have been associated with the movement of people for thousands of years. For instance, horses were introduced into North America by Spanish explorers, while pigs were introduced by the Polynesians into many Pacific islands long before the establishment of permanent European settlements. Both of these species introductions...

  • Establishing a through-boring pattern and method of test for utility poles

    Creator:
    Elkins, Lori A.
    Abstract:
    The goal of this study was to optimize a through-boring pattern that will provide adequate preservative penetration while minimizing the reduction in overall pole bending strength. Hole spacing was developed using longitudinal and transverse chemical penetration data from previous studies. Finite element analysis was used as a preliminary assessment tool...

  • Modeling changes in flexural properties of softwood beams during fungal decomposition

    Creator:
    Mitsuhashi Gonzalez, June M.
    Abstract:
    Moisture intrusion in residential structures can lead to substantial fungal decay and this damage costs billions in repair/replacement costs. The extent of damage and the rate at which it occurs are primarily dependent on the wood moisture content and temperature in the structure. Determining the risk of decay for various...

  • Supercritical fluid impregnation with biocides of wood using temperature reduction

    Creator:
    Kang, Sung-Mo
    Abstract:
    Supercritical fluid (SCF) impregnation is a promising preservative treatment method, however, the development of SCF processes has been slowed by a limited understanding of the process. Developing a better understanding of the effects of various process parameters on treatment results would allow for a more rational development of SCF impregnation....

  • Potential utilization of western juniper residues

    Creator:
    Sichamba, Kennedy
    Abstract:
    Logging and forest thinning operations generate large amounts of residues in the form of small trees, branches and foliage that are usually left on the ground to decay or are burned. These resources are readily available, but it is uneconomical to remove them from the forest. The potential utilization of...

  • Potential for Using Boron Compounds with Differing Water Solubilities in Pastes for Remedial Treatment of Utility Poles

    Creator:
    Uysal, Selim
    Abstract:
    Boron and boron compounds have been long used for pressure treatment, dip-diffusion, and remedial treatments of wood because of their proven efficacy against fungi and insects. These materials are especially attractive because their high water solubility promotes deeper penetration into wood. Other useful properties of boron include its neutral pH,...

  • 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...

  • Wood treatment by double-diffusion using copper sulfate and sodium fluoride

    Creator:
    Pavia-Jones, K. Josephine
    Abstract:
    In investigating wood treatment as a possible processing option for Alaska forest products manufacturers, the double-diffusion method using sodium fluoride followed by a copper sulfate appeared to be the most advantageous approach. Yet, little information was available as to the chemical retention after treating and its resistance to leaching. Green...

  • Performance of copper based biocides in potentially copper tolerant soils

    Creator:
    Chang, Andrew B.
    Abstract:
    Copper is an excellent biocide which has a long history of usage for protecting wood from deterioration, but some organisms have developed tolerance for this chemical. Copper tolerance among wood decay fungi is a poorly understood phenomenon that is gaining importance as cofactors such as arsenic and chromium are removed...

  • Groundwater and stormwater treatment at western wood preserving facilities : an analysis of current treatment methods

    Creator:
    Ragan, Anita M.
    Abstract:
    The Pacific Northwest is blessed with an abundance of precipitation. This rainfall, however, can have important consequences for industries that must process the resulting stormwater for proper discharge. This is particularly true of wood treatment facilities. Past management practices at wood preserving facilities located in the Western United States create...
