Quality assessment of thermally modified spruce (Picea abies (L.) Karst) and beech (Fagus sylvatica L.) wood and of the corresponding reference samples was carried out by means of non-destructive FT-NIR spectroscopic measurements and PLS regression. Oven-dry and basic density as well as MOE and MOR determined by 3-point bending tests were evaluated. The(More)
Quality assessment of thermally modified wood has evolved as one of the major fields in the research on thermal modification of wood. This study investigates NIR spectroscopy in combination with the pattern recognition method of soft independent modeling of class analogies (SIMCA). Focus is put on identifying different treatment intensities of thermally(More)
Acoustics is able to evaluate and differentiate between the intrinsic properties of visually-similar material, whether as logs on the skid site or as standing trees within an even-aged stand when it comes down to stiffness (MOE) and strength (MOR). In the last decade the practical use of acoustics on timber has gained acceptance (Bucur 1995, Andrews 2002)(More)
Studies about the time of first manifestation of atopic dermatitis in children with atopic family history. Children with atopic family history were followed prospectively during their first year of life and the time of the first manifestation of an atopic dermatitis was noted. 241 children were observed during their first six months, 197 out of these during(More)
