Global energy sources such as coal and oil are limited, and the burning of such fossil resources creates pollution problems. Wind energy offers one of several promising clean alternatives to carbon-based fuels. However, the composite materials currently available for producing wind turbine blades cannot accommodate the scale-up of wind energy due to their high price and disposal challenges (e.g...

The objective of this study was to investigate the effect of straw, sawdust, coconut husk (husk), and coconut fiber (fiber) on the welfare of stable horses by observing their resting behavior. Twenty horses with ages ranging from 3 to 21 years were used at the Equine Research Institute of the Japan Racing Association, Utsunomiya, Japan. Five horses were allocated to each bedding condition. The ...

will be easier to identify fiber quality research gaps and their linkage to the issue of enhancing forest productivity. Defining Fiber Quality Quality is generally defined as “suitability for a use” (Briggs and Smith 1986). Further precision requires statement of a specific product and the key performance requirements of that product in service. Given these product performance requirements, the...

The present study explores the physical-mechanical and tribological properties of hybrid wood fiber rockwool-reinforced asbestos-free resin-based friction materials. We developed brake composites with different contents (wood rockwool fiber) at a total fixed loading 30%. Then, were investigated on physical, mechanical, according to industry standards. results show that, increase in fiber, densi...

Tension wood generates axial tensile stress and tangential compressive stress during its formation, but the mechanism causing this stress is not yet fully understood. A micro-mechanical model is used to test different hypothetic mechanism, based on the assumption that one of the constituents of tension wood undergoes a dimensional change during the formation of the wall. The consistency between...

In tests with Pinus taeda L., most properties of wet. formed hardboard were improved by using fiber refined from wood having short, slender tracheids with thin walls. A theoretical analysIs suggested that the fibers fail in bending while under stress induced by the pressing operation. Such bending failures improve conditions for hydrogen bonding, thus improving board properties. Trachelds havmg...

In the present study, reported the generation and analysis of ESTs of cDNA libraries from cambium tissue of secondary xylem obtained of two genotypes of Eucalyptus globulus contrasting in wood density and pulp yield. The sequences were blasted and annotated to compare with genome and ESTs database of other plant species. The goal of study was to determinate wich genes was differentially express...

The current study was conducted to survey the influences of addition of alfalfa meal (AM), rice bran (RB) and wood shaving (WS) in wheat-based diets [contain soluble non starch polysaccharides (NSP)] on performance carcass characteristic and serum lipids of broilers from 11 to 42 d of age. Seven hundreds 10-d-old male Ross 308 chicks were placed into 35 pens and allocated to seven wheat-soybean...

The goal of this study was to determine the comparative properties of dry-formed medium density fiberboards (MDF) made from renewable biomass (wheat and soybean straw) and those from conventional soft wood fiber. The MDF properties evaluated were modulus of elasticity, modulus of rupture, internal bond strength, thickness swell, and screw holding capacity. The results show that MDF made from wh...
