A complementary approach using Liquid Chromatographic-Mass Spectrometric analysis was proposed to characterize phenolic compounds from the methanol-water extracts of K.ivorensis A.Chev.Two High Performance Liquid Chro...
The authors acknowledge Eti Maden Operations General Directorate,Ankara,Turkey for the boron minerals and DOT used in the study.
This study evaluated boron diff usion from raw boron minerals ulexite and colemanite with low water solubility in comparison to disodium octaborate tetrahydrate(DOT).Tests were conducted using sugi(Cryptomeria japonic...
To elucidate the development of heartwood,bark,sapwood,pith and specific gravity of wood in fastgrowing teak(Tectona grandis)plantations in Costa Rica,we sampled three trees in each of 55 plantations and modelled each...

Aims Despite the importance of stem cO_(2)efflux(Es)in ecosystem carbon cycling and energy balance,little is known about temporal variation in the temperature coefficient(Q10)and sapwood nitrogen concen-trations([N])a...
We evaluated heartwood, sapwood and bark content in teak trees. A total of 27 sample plots were laid out in teak plantations raised by State Forest Department in Kamataka covering different age groups (11-36 years),...
A desorption isotherm is a very important basis in the understanding of drying process. In this study, the desorption isotherms from the sapwood of Mexican pine (Pinus pseudostrobus Lindl.) were determined by the gr...
In this study, the Chinese fir (Cunninghamia lanceolata Hook.) specimens with different ratios of heartwood thickness to sapwood thickness (HS) were radially compressed at different compression speeds, and then ab...
Measurement of the longitudinal gas permeability was made for air-dried sapwood specimens from Masson pine (Pinus massoniana). Results showed that air-dried Masson pine sapwood was one of the most permeable softwood...

A comparative study was conducted on liquid penetration of the freeze-drying and air-drying sapwood and heartwood lumber of plantation Chinese fir (Cunninghamia lanceolata). The maximum amount of dyeing solution upt...
An experimental device able to determine the moisture content of wood usingX-ray attenuation is used to study the imbibition of beech samples (Fagus silvatica). The apparatusincludes an X-ray generator, a protective t...
