Walters seminar Final.pdf

Creator:: Walters, Helen Marie
Abstract:: Hypoxia is a naturally occurring phenomenon that happens seasonally off the Oregon coast. As a consequence, there has been a great deal of research focused around analyzing the strength and duration of the hypoxic event during the summer season. This paper, however, takes an innovative approach by looking at the...

Antioxidant activity of fractions from Quercus sideroxyla bark and identifi cation of proanthocyanidins by HPLC-DAD and HPLC-MS

Creator:: Rosales-Castro, Martha, Gonzalez-Laredo, Ruben Francisco, Rocha-Guzman, Nuria Elizabeth, Gallegos-Infante, Jose Alberto, Rivas-Arreola, Maria Jose, and Karchesy, Joseph J.
Abstract:: The most active phenolics in Quercus sideroxyla Humb. & Bonpl. residual bark were identified and evaluated following a chromatographic fractionation. Bark powder was defatted with hexane and crude extract (CE) was obtained by extraction with aqueous acetone (70%). A liquid partition with ethyl acetate was performed to produce an organic...

A numerical study of the transverse modulus of wood as a function of grain orientation and properties

Creator:: Nairn, John A.
Abstract:: Finite element analysis was used to study the effective transverse modulus of solid wood for all possible end-grain patterns. The calculations accounted for cylindrical anisotropy of wood within rectangular specimens and explicitly modeled wood as a composite of earlywood and latewood. The effective modulus was significantly reduced by growth ring...

A new soy flour-polyepoxide adhesive system for making interior plywood

Creator:: Huang, Jian, Li, Chunhong, and Li, Kaichang
Abstract:: In this study, triglycidylamine (TGA) was synthesized and evaluated as a crosslinking agent for soy flour (SF) for making five-ply plywood from yellow poplar. Glycerol polyglycidyl ether (GPE) and trimethylolpropane triglycidyl ether (TTE) were also investigated as crosslinking agents for SF as adhesive for plywood. The plywood panels bonded with...

Revisiting the neutral axis in wood beams

Creator:: Davis, Philip M., Gupta, Rakesh, and Sinha, Arijit
Abstract:: For wood beams, it is often assumed that the neutral axis (NA) is located at the centroid of the beam. This would be the case for isotropic and homogeneous materials but these prerequisites are not valid for wood. The varying grain patterns and knots located throughout wood make wood anisotropic...

Situating senior women in the literacy landscape of North Africa

Creator:: Rice, Laura and Hamdy, Karim
Abstract:: Although literacy programs in North African countries vary in method, management approach, and in content emphasis, their discourse is strikingly similar: It focuses too often on learners' deficits and considers the condition of these “illiterate” subjects, i.e. persons lacking the 3Rs, as a “disease” against which a war of eradication...

Effect of grain angle on shear strength of Douglas-fir wood

Creator:: Gupta, Rakesh and Sinha, Arijit
Abstract:: The effect of grain angle (GA) on shear strength of Douglas-fir has been evaluated. Shear block specimens with a GA varying from 0 to 90° was loaded in the shear plane, resulting in failure mode transitioning from parallel to grain shear to rolling shear. As expected, shear strength decreased as...

Strain distribution and load transfer in the polymer-wood particle bond in wood plastic composites

Creator:: Schwarzkopf, Matthew and Muszynski, Lech
Abstract:: The load transfer between wood particles and the matrix was analyzed by observation of the strain patterns in thin films of high density polyethylene (HDPE) with embedded wood particles subjected to tensile loading. Optical measurement techniques based on the digital image correlation (DIC) principle were employed for quantitative measurement of...

Characterizing perpendicular-to-grain compression (C-perpendicular to) behavior in wood construction

Creator:: Basta, Craig Thomas, Gupta, Rakesh, Leichti, Robert J., and Sinha, Arijit
Abstract:: Current compression perpendicular-to-grain (C-perpendicular to) design values for wood members are based on mean stress obtained from ASTM D143 specimen. The standard ASTM test with metal on wood bearing has limited applicability in modern construction assemblies with C-perpendicular to loading scenarios. Previous work has shown that end-bearing conditions and wood-on-wood...
