tall oil bio-refinery water repellents cellulosic fibers dynamic water vapor sorption
2024/1/10
This study investigates the effect of renewable formulations based on tall oil bio-refinery products on the water vapor sorption and interfiber strength of cellulosic fibers as well as on the properti...
Spectrometric prediction of wood basic density by comparison of different grain angles and variable selection methods
Spectrometric prediction wood basic density
2023/6/2
Background:Wood basic density (WBD) is one of the most crucial wood property in tree and mainly determined the end use of wood for industry. However, the measurement WBD is time- and cost-consuming, w...
Influence of site conditions and silvicultural practice on the wood density of Scots pine (Pinus sylvestris L.) – a case study from the Doksy locality, Czech Republic
shelterwood regeneration clearcut forest site softwoods physical properties variability
2018/3/6
After spruce, the Scots pine (Pinus sylvestris Linnaeus) is the second most important commercial coniferous tree
species in the Czech Republic. However, we are finding out that awareness of the varia...
THE INFLUENCE OF CLIMATE ON TREE-RING MAXIMUM LATEWOOD DENSITY IN NORWAY SPRUCE (Picea abies (L.) Karst.) AT TWO SITES IN SLOVENIA
Norway spruce (Picea abies (L.) Karst.) climate maximum latewood density MXD densitometry
2009/11/27
Norway spruce (Picea abies (L.) Karst.) is frequently the object of dendrochronological research owing to its distribution, wood structure and longevity. The Norway spruce chronologies published in Sl...
Determination of relationships between density, amount of glue and mechanical properties of OSB
oriented strand board (OSB) density bending strength modulus of elasticity tensile strength perpendicular to the board surface amount of glue PMDI glues
2009/7/21
This paper deals with problems of the effect of changes in density and amount of glue on mechanical properties of OSB (oriented strand boards). Tests of mechanical properties were carried out on OSB...
Use of the Pilodyn for Estimating Basic Density and Its Applicability to Density-based Classifying of Cryptomeria japonica Green Logs
Pilodyn basic density log classification green condition Cryptomeria japonica
2009/3/6
We used a Pilodyn for estimating basic density in the green condition for the purpose of classifying logs of Cryptomeria japonica D. Don based on their density. The relationships between Pilodyn pene...
Longitudinal Changes of Basic Density and Non-Destructive Quality Evaluation Using the Pilodyn in Todomatsu（Abies sachalinensis）Plus Tree Clones
todomatsu clone longitudinal change basic density Pilodyn penetration
2009/3/4
The longitudinal changes in the basic density of disks (mean Bd) of todomatsu (Abies sachalinensis) were investigated using plus-tree clones and breeding-material clones. The relationship between Pilo...
Harvest block spatial configuration as a function of logging road density：Do larger more aggregated blocks create less road?
Harvest block spatial configuration logging road density
2009/2/5
Logging roads are a large component of forest management and have been directly linked to a variety of negative ecological effects, including forest fragmentation. Much research exists that views logg...
Comparative Study of Wood Density by Specific Amount of Void Volume（Porosity）
Wood density Porosity Moisture content Green volume method Oven dry method Maximum moisture content method
2009/1/13
Various methods were progressively investigated to determine wood density within the most reliable void volume (porosity) values. Three softwood species of Bornmulleriana fir (Abies bornmulleriana Mat...
