Biomass conversion factors, expansion factors and leaf dry matter content for pinus
(2018)
There are two generally accepted approaches to the calculation of woody biomass. First, allometric
equations that allow estimation of tree biomass using easily measured tree properties (diameter, tree height etc.),
the ...
The effect of treatment time on dimensionally stability, moisture content and mechanical properties of heat treated anatolian chestnut (Castanea sativa Mill.) wood
(Wood Research, 2009)
In this study, the effect of treatment time on dimensional stability, moisture content, and mechanical properties of heat-treated Anatolian chestnut (Castanea sativa Mill.) were investigated. Test specimens were subjected ...

Ormanlardan sağlanan ürün ve hizmetlerin devamlılığının sağlanabilmesi için bu önemli doğal kaynağın kalitesinin ve alansal büyüklüğünün artırılması gerekmektedir. Bu kapsamda doğal orman kaynakları üzerindeki baskı ...
Determining ergonomic factors of loading machines using in forestry operations in Turkey
(Bartın Üniversitesi, Orman Fakültesi, 2013)
Loading machines in various types are generally used in forest depots in Turkey for loading and stacking the forest products. However, the risks accompanying this development threaten the health of the operators working ...
Effects of boron Impregnation and heat treatment on some physical and mechanical properties of spruce and pine wood
(Karadeniz Teknik Üniversitesi, 2010-11-04)
This study evaluated the effects of boron impregnation and heat treatment on some physical and mechanical properties of wood. Spruce and pine wood samples were treated with 4% aqueous solution of both boric acid (BA) and ...
Effect of heat treatment of wild cherry wood on abrasion resistance and withdrawal capacity of screws
(Drvna Industrija, 2015-11-06)
In its wise use, many properties of wood are important. Among these properties, wood abrasion
resistance (AR) and withdrawal capacity of screws (WCS) are deemed to be relatively signifi cant. It is well know
that heat ...
Changes in the chemical structure of thermally treated wood
(Bioresource Technology, 2010)
Changes in the chemical structure of hornbeam and uludag fir woods during thermal treatment were investigated at three temperatures (170, 190, and 210 oC) and three durations (4, 8, and 12 hours). After thermal treatment, ...
The effect of heat treatment on some mechanical properties and color changes of Uludag fir wood
(Taylor & Francis, 2010-03-08)
In this study, the effects of heat treatment on color, mass loss,
compression strength, and hardness of Uludag fir (Abies bornmulleriana
Mattf.) were investigated. Wood specimens conditioned at
a relative humidity of ...
