The article reports the first radiocarbon dating of a live African baobab (Adansonia digitata L.), by investigating wood samples collected from 2 inner cavities of the very large 2-stemmed Platland tree of South Africa. Some 16 segments extracted from determined positions of the samples, which correspond to a depth of up to 15–20 cm in the wood, were processed and analyzed by accelerator mass s...

Treatments of knot-containing spruce wood blocks with a paramagnetic salt, gadolinium (III) chloride, in combination with solvent pretreatments, were evaluated as strategies to enhance the visualization of wood features by magnetic resonance imaging (MRI). Initial experiments with clear wood and excised knot samples showed differences in moisture uptake after pretreatments with selected solvent...

Kraft pulp produced from juvenile and mature wood from thirty-two-yearold Corymbia citriodora trees was evaluated. The stem was subdivided into regions of juvenile and mature wood, and then it was transformed into chips. These materials were then cooked in the Laboratory of Pulp and Paper at São Paulo State University (UNESP, Botucatu, SP, Brazil) and the physico-mechanical properties of the pu...

In this research, efficiency of Iranian forest and rangeland decision making unit was assessed using non-parametric method. Inputs and outputs determined by field research and with applying a Delphi method the final input and output variables selected. Forty five wood-producing units (forestry plans) in three northern Iranian province were studied using Data Envelopment Analysis. The efficiency...

Wood is not under all circumstances an appropriate building material. Beside others, structural properties and biological durability determine the limits for the use of wood. Until recently, the only industrial applied method to improve the durability of wood was impregnating with toxic wood preservatives. Although much progress has been made in improving the fixation of preservatives (i.e. emi...

Degradation of wood, being a natural process, leads to destruction of wooden objects of historic and cultural value, resulting in loss of cultural heritage. Wood can survive centuries or even thousands of years, if kept in an environment, which limits microbial activity. In an unfavourable environment physical, chemical and morphological modifications of wood also take place as a result of biod...

Wood elements and anatomical ratio of Dipterocarpus indicus were studied to evaluate variation among populations and to recommend for end selection. The variation of wood element [fibre length (FL), fibre diameter (FD), lumen diameter (LD), cell wall thickness (CWT), double wall thickness (DWT), and lumen volume (LV)] and anatomical ratio [fibre lumen area (FLA), slenderness ratio (SR) and runk...
