Effects of environmental factors on decay rates of selected white- and brown-rot fungi

Creator:: Gonzalez, June Mitsuhashi and Morrell, Jeffrey J.
Abstract:: Assessing the impact of fungal decay in wood structures poses a major challenge for building inspectors. Although models have been developed to predict degradation rate of building components in varying climatic conditions, most are hampered by the lack of fundamental data on effects of fungal attack on engineering properties. Developing...

Formation of zinc oxide films using submicron zinc particle dispersions

Creator:: Rajachidambaram, Meena S., Varga, Tamas, Kovarik, Libor, Sanghavi, Rahul, Shutthanandan, Vaithiyalingam, Thevuthasan, Suntharampillai, Han, Seung-Yeol, Chang, Chih-Hung, and Herman, Gregory S.
Abstract:: The thermal oxidation of submicron metallic Zn particles was studied as a method to form nanostructured ZnO films. The particles used for this work were characterized by electron microscopy, x ray diffraction, and thermal analysis to evaluate the Zn-ZnO core shell structure, surface morphology, and oxidation characteristics. Significant nanostructural changes...

De novo synthesis of a sunscreen compound in vertebrates

Creator:: Osborn, Andrew R., Almabruk, Khaled H., Holzwarth, Garrett, Asamizu, Shumpei, LaDu, Jane, Kean, Kelsey M., Karplus, P. Andrew, Tanguay, Robert L., Bakalinsky, Alan T., and Mahmud, Taifo
Abstract:: Ultraviolet-protective compounds, such as mycosporine-like amino acids (MAAs) and related gadusols produced by some bacteria, fungi, algae, and marine invertebrates, are critical for the survival of reef-building corals and other marine organisms exposed to high-solar irradiance. These compounds have also been found in marine fish, where their accumulation is thought...

Collaboration and tension between institutions and units providing data management support

Creator:: Wright, Stephanie, Whitmire, Amanda L., Zilinski, Lisa D., and Minor, David
Abstract:: A panel of speakers from three universities explored their challenges and progress in building programs to support research data management, whether within the library system or with research offices or computing groups. Since 2012 Oregon State University has partnered with its research office and graduate school, helping students prepare data...

Effect of treatment postfixation practices on copper migration from alkaline-copper-treated Douglas-fir lumber

Creator:: Ye, Min and Morrell, Jeffrey J.
Abstract:: The potential for preservative migration from treated wood exposed in or above aquatic environments has become a major concern in some parts of the United States. Best management practices (BMP) were designed to decrease the potential environmental footprint of treated wood, but there are few studies assessing the efficacy of...

Informatics and Standards for Nanomedicine Technology

Creator:: Thomas, Dennis G., Klaessig, Fred, Harper, Stacey L., Fritts, Martin, Hoover, Mark D., Gaheen, Sharon, Stokes, Todd H., Reznik-Zellen, Rebecca, Freund, Elaine T., Klemm, Juli D., Paik, David S., and Baker, Nathan A.
Abstract:: There are several issues to be addressed concerning the management and effective use of information (or data), generated from nanotechnology studies in biomedical research and medicine. These data are large in volume, diverse in content, and are beset with gaps and ambiguities in the description and characterization of nanomaterials. In...

Relationship between incipient decay, strength, and chemical composition of Douglas-fir heartwood

Creator:: Winandy, Jerrold E. and Morrell, Jeffrey J.
Abstract:: A new laboratory technique to simulate the initiation of wood decay and to assess the effects of incipient decay on material properties is described. Douglas-fir heartwood specimens were exposed to brown-rot (Postia placenta and Gloeophyllum trabeum) fungi for various periods. Bendlng properties were determined by nondestructive and destructive tests, and...

Properties and decay resistance of preservative-treated Douglas-fir flakeboard

Creator:: Jeihooni, Asghar, Krahmer, Robert L., and Morrell, Jeffrey J.
Abstract:: The effect of pretreatment of Douglas-fir flakes with CCA-C, borate, and azaconazole on properties of flakeboard was studied. Flakes had higher retention levels of CCA-C and borate in their ends than in their centers. The distribution of chemicals was uniform in panels, which indicates that the chemicals did not migrate...

Copper, chromium, and arsenic levels in soils surrounding posts treated with chromated copper arsenate (CCA)

Creator:: Morrell, Jeffrey J. and Huffman, Jacob
Abstract:: The levels of copper, chromium, and arsenic in soil surrounding CCA-treated posts and beneath CCA-treated stakes were investigated at a plot near Gainesville, Florida. Metal levels were elevated in soil immediately adjacent to the treated wood, but decreased with distance away or depth. Mean extractable arsenic levels ranged from 1.74...

Patterns of fungal attack in wood-plastic composites following exposure in a soil block test

Creator:: Mankowski, Mark and Morrell, Jeffrey J.
Abstract:: The ability of white and brown rot fungi to colonize wood-plastic composites was investigated by measuring weight loss and anatomical changes. Three composite materials were evaluated. The material containing a 70/30 wood-high density polyethylene (HDPE) mixture was most susceptible to fungal attack, while two different 50/50 wood-HDPE composites experienced little...
