Hygroscopicity of Longitudinally Compressed Wood [PDF]
Acta Silvatica et Lignaria Hungarica, 2017 AbstractKnowledge of hygroscopicity is extremely important both in the use of native wood and modified wood. In this study, the modification method was steaming at 100 °C, then longitudinal compression at a rate of 20%. The moisture content (MC) of treated and untreated green beech wood (Fagus sylvaticaL.) was reduced in a climate chamber with gradual ...

Data value storage for compressed semi-structured data [PDF]
, 2013 Growing user expectations of anywhere, anytime access to information require new types of data representations to be considered. While semi-structured data is a common exchange format, its verbose nature makes files of this type too large to be ...

Physical and Morphological Changes in Heat-Treated and Densified Fast-Growing Timber Material [PDF]
E3S Web of Conferences, 2023 Heat treatment is a modification method that can alter the polymeric components of wood (cellulose, hemicellulose and lignin). Densification technology has emerged as one of the promising technologies capable of improving the properties of low-density ...

Mechanics of the Compression Wood Response [PDF]
Plant Physiology, 1970 Righting of two tilted white pine (Pinus strobus L.) stem leaders by compression wood formation was followed for 16 weeks. The natural curves and three deflection curves under added end loads were determined from weekly field photographs. Data for self-loading and cross sectional diameters were interpolated from original estimated and final ...

Steam or Heat Fixation of Compressed Wood [PDF]
, 2007 Dimensional stability can be improved by either steaming or heating wood while the wood is in a compressed state. This study investigated the effect of steam or heat on fixation of compression set and the effect of these treatments on hardness ...

Accelerated Air-coupled Ultrasound Imaging of Wood Using Compressed Sensing
BioResources, 2015 Air-coupled ultrasound has shown excellent sensitivity and specificity for the nondestructive imaging of wood-based material. However, it is time-consuming, due to the high scanning density limited by the Nyquist law.

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010 The wood is heterogenous material compound from substance of cell walls and air. It is colloidal capillary-cellular material with ortogonal anisotropy (Babiak, 1976). The wood has possibility to bound liquids and gases into the structure.
