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...
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...
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...
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...
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...
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...
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...
La lagune de Nador se caractérise par un écosystème semi-fermé, en communication avec la mer par une étroite passe. Cet écosystème est sous l'influence de plusieurs facteurs externes tels que l'ensoleillement, l'apport en eau douce, les eaux de ruissellement, le lessivage des champs agricoles et les eaux usées urbaines. L'influence...
Human cathelicidin antimicrobial peptide (CAMP/LL-37) is a cationic antimicrobial peptide that is widely expressed by myeloid and epithelial cells at the human-environment interface. It possesses broad spectrum antimicrobial capacity against bacteria, fungi and viruses. In addition to its direct antimicrobial activity, CAMP/LL-37 also attracts and recruits monocytes, neutrophils and other...
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...
