Thermal degradation of bending properties of structural wood and wood-based composites

Creator:: Sinha, Arijit, Gupta, Rakesh, and Nairn, John A.
Abstract:: Wood and wood-based composites are being used extensively in single-family residential dwellings. Therefore, it is important to categorize their response when exposed to elevated temperatures for a sustained period of time. In fire-resistant design for wood structures, the main goal is to ensure that enough structural integrity is maintained, during...

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...

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...

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...

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...

Postpeak residual capacity of nailed connections of a shear wall

Creator:: Sinha, Arijit
Abstract:: To quantify the postpeak residual capacity and to gain insights into the load transfer mechanism of a shear wall, nail connection tests were performed on salvaged connections after a monotonic shear wall test loaded up to peak load. Experimental results reveal that there is a loss of strength in most...

Kinetic Prefactors of Reactions on Solid Surfaces

Creator:: Campbell, Charles T., Árnadóttir, Liney, and Sellers, Jason R. V.
Abstract:: Adsorbed molecules are involved in many reactions on solid surfaces that are of great technological importance. As such, there has been tremendous effort worldwide to learn how to theoretically predict rates for reactions involving adsorbed molecules. Theoretical calculations of rate constants require knowing both their activation energy and prefactor. Recent...

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...

Determination of local material properties of OSB sample by coupling advanced imaging techniques and morphology-based FEM simulation

Creator:: Sebera, Vaclav and Muszynski, Lech
Abstract:: The goal was to determine local mechanical properties inside of oriented strand board (OSB) based on a realistic morphology-based finite element (FE) model and data acquired from a physical test performed on the same material. The spatial information and local grayscale intensity from CT-scans obtained from small OSB sample was...

On the Consequences of Living without Facial Expression

Creator:: Bogart, Kathleen R., Cole, Jonathan, and Briegel, Wolfgang
Abstract:: Although the importance of the face in communication is well-known, there has been little discussion of the ramifications for those who lack facial expression: individuals with facial paralysis such as Bell’s palsy and Möbius syndrome, and facial movement disorders like Parkinson’s disease. By examining the challenges experienced by these individuals,...
