in this research, effect of using hornbeam and beech branch woods in admixture with birch stem wood on their cmp pulp properties. using percentage of branch woods, with 20% constant content for birch stem wood, were 0, 16, 40, 56 and 80 in final mixture of hardwoods. the results indicated that cooking time, to reach 85% yield and under same cooking condition, and also refining quantity, to reac...

in this research, the bioinsising impact of two wood decay fungi (pysisporinus vitreus and xylaria longipes) on radial air permeability and moisture diffusion coefficient of spruce wood (picea abies) was investigated. fungal cultivation was performed in an incubator at 25 °c and 85% relative humidity for 15, 30 and 45 days. results showed that the permeability, moisture diffusion and mass loss ...

abstract plant roots absorb water and minerals from soil solution. plant production is a function of root distribution and its activity in soil. by increasing root density in soil unit volume, roots absorb more water and minerals. this implies that knowledge of root development is an important factor for crop production. to determine the most suitable amount of water for the maximum development...

a 6 week study was conducted to assess the effects of wood betony (wb), stachys lavandulifolia extract on growth performance, hematological and biochemical parameters of common carp, cyprinus carpio. different levels of the wb extract (0, 2, 4 and 8 % weight per weight, w/w, 0wb, 2wb, 4wb and 8wb) in the diet were used. the results showed that final weight and weight gain were significantly imp...

Superconducting transition temperatures (Tc’s) of MgB2, Mg1−xCaxB2, Mg1−xNaxB2, and Mg1−xAlxB2 are studied within the McMillan approximation using electronic and structural information obtained from density functional theory within the generalized gradient approximation. The density of states and Tc of MgB2 are both shown to be extremely sensitive to volume; in fact the density of states around...

1. The method of biomass estimation based on a volume-to-biomass relationship has been applied in estimating forest biomass conventionally through the mean volume (m 3 ha-1). However, few studies have been reported concerning the verification of the volume-biomass equations regressed using field data. The possible bias may result from the volume measurements and extrapolations from sample plots...
