Effect of Additional Mass on the Apparent Young’s Modulus of a Wooden Bar by Longitudinal Vibration

BioResources, 2014
We investigated the influence of an additional mass bonded on a wooden bar on its apparent Young’s modulus based on a longitudinal vibration theory. Rectangular bars of Sitka spruce (Picea sitchensis Carr.) were used as experimental materials.

Effect of microwave drying on drying kinetics, physico-mechanical properties, and microstructure of plantation-grown Hevea brasiliensis wood

iForest - Biogeosciences and Forestry
We explored the microwave drying of rubber tree (Hevea brasiliensis) wood using a multifaceted approach that encompasses various aspects. The primary objective was to examine drying behavior, drying time, moisture distribution across the core and surface,

Decision-making model for the specification of wood as an input for the production of wooden musical instruments

Central European Forestry Journal, 2023
The main aim of the paper is to propose formalised decision-making model for the selection of suitable parts of raw wood for the production of musical instruments and to decrease uncertainty in the purchasing process.

Methylation biomarkers can distinguish pleural mesothelioma from healthy pleura and other pleural pathologies

Molecular Oncology, EarlyView.
We developed and validated a DNA methylation–based biomarker panel to distinguish pleural mesothelioma from other pleural conditions. Using the IMPRESS technology, we translated this panel into a clinically applicable assay. The resulting two classifier models demonstrated excellent performance, achieving high AUC values and strong diagnostic accuracy.

Wood Properties and Processing [PDF]

, 2020
Wood-based materials are CO2-neutral, renewable, and considered to be environmentally friendly. The huge variety of wood species and wood-based composites allows a wide scope of creative and esthetic alternatives to materials with higher environmental impacts during production, use and disposal.

Particle size distribution of Japanese cedar chip converted from boards using a disc chipper and its relationships with disc rotation speed and board feed speed

Journal of Wood Science
The effects of disc chipper rotation speed and raw material feed speed on the particle size distribution of wood chips produced were investigated to develop an efficient technique for producing ideal sized chips for the stable operation of combined heat ...
