Wood characterization of Eucalyptus paniculata Smith species

Revista Principia, 2022
Eucalypts have not been well accepted for construction use by civil societies in different nations. For the elimination of these cultural barriers, there is the demand for better knowledge of the physical-mechanical properties of these silvicultural ...

Creep Properties of Densified Wood in Bending

Forests, 2022
Thermo-hydro-mechanical (THM)-densified timber is rarely used in construction, although its mechanical properties are in many cases excellent. The main reason for its rare use is set-recovery, which reduces the degree of densification over time so that the mechanical properties deteriorate.

Comparison of some wood properties of juvenile black pines of different origin planted in the same habitat

Maderas: Ciencia y Tecnología, 2021
Black pine (Pinus nigra) is a significant raw material source for the forest products industry in Turkey. The purpose of this research was to study some chemical, anatomical, physical, and mechanical properties of wood obtained from juvenile black pines

Estimation of finite population mean in two-phase sampling with known coefficient of variation of an auxiliary character

Statistica, 2013
In this paper a double (or two-phase) sampling version of (Singh and Tailor, 2005) estimator has been suggested along with its properties under large sample approximation. It is shown that the estimator due to (Kawathekar and Ajgaonkar, 1984) is a member

Penetration and effectiveness of micronized copper in refractory wood species [PDF]

, 2016
The North American wood decking market mostly relies on easily treatable Southern yellow pine (SYP), which is being impregnated with micronized copper (MC) wood preservatives since 2006. These formulations are composed of copper (Cu) carbonate particles (

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.

Improving interfacial adhesion in pla/wood biocomposites [PDF]

, 2013
Two reactive coupling agents, N,N-(1,3-phenylene dimaleiimide) (BMI) and 1,1-(methylenedi-4,1-phenylene)bismaleimide (DBMI) were used to improve interfacial adhesion in PLA/wood composites.

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,
