  • Characterization of Fungal Communities in Selected Wood Species by Field Exposure Tests

    Creator:
    Torres-Andrade, Paola A.
    Abstract:
    Fungi are the primary biological agents of wood deterioration and cause major economic losses of wood products globally. Wood in outdoor applications tends to remain wet for extended time periods, making it susceptible to fungal attack. Understanding the factors involved in fungal colonization of wood is important for developing improved...

  • 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....

  • Utilization of ground peanut husk as an alternative fiber material for particleboard

    Creator:
    Newton, Jacob A.
    Abstract:
    This research examined the potential for using peanut husk as a fiber alternative to wood in the production of melamine-formaldehyde (MF) particleboard. MF resin was used to produce panels with one, three, six, nine or 12 percent resin contents. Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB)...

  • 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...

  • Fungal colonization of Douglas-fir sapwood

    Creator:
    Kang, Sung-Mo
    Abstract:
    The fungi that cause mold and stain of freshly sawn lumber result in millions of dollars in losses to the forest products industry. Stain and mold are typically prevented by either kiln drying or by application of a topical fungicide. While these treatments are effective, kiln drying is costly and...

  • 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...

  • The effects of tree position and silvicultural practices on treatability of Douglas-fir lumber

    Creator:
    Hong, Seungdo
    Abstract:
    In spite of the lack of accurate information about the treatability of western wood species with waterborne wood preservatives, consumption of these products continues to increase. Western wood species, notably Douglas-fir, are notoriously difficult to treat with waterborne systems, yet there is relatively little data on the effects of wood...

  • 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,...

  • 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...

  • The Effect of Sill Height on Decay in Air-Seasoning Crossties

    Creator:
    Rogers, Leon R.
    Abstract:
    The sustainable use of wood for rail ties requires chemical treatment to increase service life and maintain structural integrity. Treatment can only be applied after lengthy air-seasoning to reduce moisture content in wood, but seasoning leaves ties exposed to attack by decay fungi for up to a year. One factor...
