Performance of wood treated with prospective organic surface protectants upon outdoor exposure: FTIR spectroscopic analysis of weathered surfaces

Creator:: Schauwecker, Christoph F., McDonald, Armando G., and Morrell, Jeff J.
Abstract:: Visual appeal of wood is as important as its structural integrity in outdoor applications. Discoloration and checking of wood favor the utilization of alternative materials for outdoor cladding and decking. Lignin depolymerization is one of the critical processes leading to weathering. In the present paper, the potential of different classes...

Recursively partitioned mixture model clustering of DNA methylation data using biologically informed correlation structures

Creator:: Koestler, Devin C., Christensen, Brock C., Marsit, Carmen J., Kelsey, Karl T., and Houseman, E. Andres
Abstract:: DNA methylation is a well-recognized epigenetic mechanism that has been the subject of a growing body of literature typically focused on the identification and study of profiles of DNA methylation and their association with human diseases and exposures. In recent years, a number of unsupervised clustering algorithms, both parametric and...

Higher order asymptotics for negative binomial regression inferences from RNA-sequencing data

Creator:: Di, Yanming, Emerson, Sarah C., Schafer, Daniel W., Kimbrel, Jeffrey A., and Chang, Jeff H.
Abstract:: RNA sequencing (RNA-Seq) is the current method of choice for characterizing transcriptomes and quantifying gene expression changes. This next generation sequencing-based method provides unprecedented depth and resolution. The negative binomial (NB) probability distribution has been shown to be a useful model for frequencies of mapped RNA-Seq reads and consequently provides...

Development and evaluation of new curing agents derived from glycerol for formaldehyde-free soy-based adhesives in wood composites

Creator:: Huang, Jian, Gu, Kai, and Li, Kaichang
Abstract:: Abstract: Three novel curing agents ( I , II , and III) were synthesized from epichlorohydrin and ammonium hydroxide. The combinations of soy flour (SF) with one of the curing agents (SF- I , SF- II , and SF- III ) were investigated as adhesives for making interior plywood. Water...

Investigation of bamboo pulp fiber-reinforced unsaturated polyester composites

Creator:: Qiu, Renhui, Liu, Wendi, and Li, Kaichang
Abstract:: Mechanical pulp fibers (MPFs) and chemical pulp fibers (CPFs) from moso bamboo have been characterized in terms of their length and width distributions, and their reinforcing effects in unsaturated polyester (UPE) composites have also been investigated. CPF-UPE composites had much higher tensile strength, flexural strength, and flexural modulus than MPF-UPE...

Stereomicroscopic optical method for the assessment of load transfer patterns across the wood-adhesive bond interphase

Creator:: Schwarzkopf, Matthew and Muszyński, Lech
Abstract:: The mechanical performance of wood-based composites is determined by the mechanical properties of their individual components and the effective load transfer between these components. In laminated wood composites, this load transfer is facilitated by the adhesive bond. The experimental methodology developed in this study measures and analyzes the full-field deformation...

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...

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...

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...

Creator:: Romero Montes, Gaspar, Lozoya Saldana, Hector, Mora Aguilera, Gustavo, Fernandez Pavia, Sylvia, and Gruenwald, Niklaus J.
Abstract:: SEE ARTICLE FOR ABSTRACT IN SPANISH. English Abstract: In order to study the quantitative relationship between tuber yield of two potato (Solanum tuberosum L.) cultivars (‘Alpha’, susceptible, and ‘Zafiro’, moderately resistant to late blight), and severity of the pathogen in Toluca, México, managed by weekly foliar sprays of 0.575 kg...
