Utilization of temperature kinetics as a method to predict treatment intensity and corresponding treated wood quality : durability and mechanical properties of thermally modified wood [PDF]

open access: yes, 2014
Wood heat treatment is an attractive alternative to improve decay resistance of wood species with low natural durability. However, this improvement of durability is realized at the expense of the mechanical resistance.

Mid-infrared absorption properties of green wood [PDF]

open access: yes, 2013
There is a lack of quantitative data on the penetration depth and the amount of energy absorbed by green wood under infrared (IR) radiation. This lack of knowledge is a potential barrier to the development of IR heating as an alternative to soaking as a ...

Ecotoxicity and fungal deterioration of recycled polypropylene/wood composites: Effect of wood content and coupling [PDF]

open access: yes, 2013
Polypropylene (PP)/wood composites were produced by homogenization in a twin-screw extruder and injection molding of tensile bars. Their mechanical properties were determined before and after exposure to biological treatment, and the effect of the ...

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

open access: yesStatistica, 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

Improving interfacial adhesion in pla/wood biocomposites [PDF]

open access: yes, 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.

The effect of mass loss on mechanic properties of heat-treated paulownia wood [PDF]

open access: yes, 2009
In this study, the eff ect of mass loss on mechanic properties of Paulownia (Paulownia elongata) wood was investigated. For this study, three diff erent temperatures (160, 180, and 200oC) and durations (3, 5, and 7 hours) were carried out.

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

open access: yesBioResources, 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.
