Pillaging Bloodwood: An Exploratory Examination of Illegal Deforestation in Guinea-Bissau Through Forest Disturbance Algorithms and Unsupervised Clustering Techniques

Creator:: Walters, Alexander E.
Abstract:: Environmental crime around the world, such as trafficking in illegal timber, is directly related to political instability. Traffickers exploit weak, fragile, and chaotic political circumstances to illegally extract high-value commodities, challenging the extent to which conservation goals are achievable in resource rich developing countries. Rosewood is the largest traded endangered...

The Alexander polynomial

Creator:: Scherich, Nancy
Abstract:: The Alexander polynomial is a well understood classical knot invariant with interesting symmetry properties and recent applications in knot Floer homology. There are many different ways to compute the Alexander polynomial, some involving algebraic techniques and others more geometric or combinatorial approaches. This is an interesting example of how different...

Total Kinetic Energy Release in the Fast Neutron Induced Fission of 237Np

Creator:: Pica, Ashley
Abstract:: The total kinetic energy (TKE) in the fast neutron induced fission of 237Np was measured for neutron energies from En = 2.6 – 45.7 MeV at the LANSCE- WNR facility. The postTKE release decreases non-linearly with increasing incident neutron energy and can be represented as TKE(MeV) = (169.365 ± 1.551)...

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...
