Abstract To predict the mechanical properties of wood in transverse direction, this study used machine learning to extract anatomical features from cross-sectional stereograms. Specimens with different orientations ray parenchyma cell were prepared, and their modulus elasticity (MOE) rupture (MOR) measured by a three-point bending test. The orientation density ( $$\rho $$ <mml:math xmlns:mml="h...

Carbon fibers were pretreated by ultrasonic agitation and then were used to manufacture carbon fiber-reinforced wood composites (CFRWCs). The modulus of rupture (MOR) and the modulus of elasticity (MOE) for the CFRWCs were measured. The effects of the compounding pattern and proportion of carbon fiber on the dynamic performance were investigated by dynamic thermomechanical analysis (DMA) and fi...

Investigations have continued for production high performance agro-based composites using environmentally acceptable approaches. This study examines the role of adding amide-containing biopolymers during synthesis of urea–formaldehyde (UF) on properties of adhesive produced, especially its adhesion potential. The environmental performance of UF-resin synthesized in the presence of modified amid...

The aims of this study were to introduce a new laboratory microwave device developed for the modification of wood properties and to examine the effect of microwave radiation on moisture loss, surface temperature, and mechanical properties (the static modulus of elasticity MOE, and the modulus of rupture MOR) of Norway spruce (Picea abies). The device was developed for a continuous modification ...

The objective of this research was to develop an integrated process to produce biogas and high-quality particleboard using saline creeping wild ryegrass (CWR), Leymus triticoides through anaerobic digestion (AD). Besides producing biogas, AD also serves as a pretreatment method to remove the wax layer of CWR for improving binding capability and then the residue is used to produce high-quality p...

dried figs collected from various exporting companies (2,461 samples) and local stores (219 samples) were analyzed using reverse-phase high-performance liquid chromatography (rp-hplc) to determine and compare the incidence of aflatoxins, the effectiveness of the regulation limits and monitoring system to select non-compliant samples and the mean daily aflatoxin exposures. the incidence rates of...

Modulus of rigidity (GLT) of veneer laminates was shown to be unrelated to dynamic modulus of elasticity (Eo) of single veneers and also, within the range of samples tested. unrelated to specific gravity. Values determined by the flexure test (GLR) were consistent with those from standard plate shear tests (G£T)' THE OBJECTIVE of the study reported here was to determine whether modulus of rigid...

Black spruce is widely used for lumber production in Eastern Canada, and it has the potential to replace trembling aspen paper birch oriented strand board (OSB) manufacturing. This study evaluated bending modulus of elasticity (MOE) rupture (MOR), internal bond (IB), thickness swelling (TS) OSB panels made from black strands how they were affected by geometry. All met CSA O437 (1993) standard c...

In this study wheat straw was taken from Ankara province. In order to produce dry process MDF, urea formaldehyde resin was used at the ratio of 8 %, 10 % and 12 %, 1 % ammonium chloride was used as hardening agent on the basis of dry fiber weight. On the other hand, 5, 6 and 7 min. pressing times were applied. Alcohol benzene, cold water, hot water and 1 % NaOH solubility of wheat straw were 5....
