Surface roughness in relation to altitude of hornbeam wood

open access: yesMadera y Bosques, 2018
Hornbeam wood (Carpinus betulus) is a native species from Iran and covers 33% of the commercial volume of Iranian woods. Surface quality of solid wood products is one of the most important properties influencing further manufacturing processes such as finishing or strength of adhesive joint. Wood surface roughness is affected by growth condition.

Comparitive study of different hornbeams (carpinus betulus L.)

open access: yesGradus
The industrial application of hornbeam is significantly hindered by its fluted growth, mainly due to the poor output of the sawmill. Our study seeks to enhance the understanding of wood science and the wood business by examining the physical-mechanical characteristics of cylindrical and fluted hornbeams, while considering various site factors. Hornbeam

Biometrical properties of hornbeam fibers from Astara

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2011
This research was performed to investigate fiber biometrical properties (length, diameter and fiber thickness) of hornbeam species from Astara in Iran. Initially, disks were prepared with three trees of hornbeam species and then fiber isolation was carried out using Franklin method.

Bonding Acetylated Hornbeam Wood (Carpinus betulus L.)

open access: yesPro Ligno, 2018
Hornbeam (Carpinus betulus L.) is a subsidiary tree species found in Hungary’s hill and mountain forests and it covers about 5.2% of the forest area. It can also be found almost all over Europe, from Sweden to Western Asia. In previous studies, it was found that acetylation – wood modification using acetic anhydride – improves the physical, mechanical,

Engineering properties of Hornbeam wood in Veisar region

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2000
To determine major engineering properties of Hornbeam wood (Carpinus betulus L.) in Vaisar region of Caspian Forests (North of Iran), adopting ASTM (D-143) Standard specifications, the matched small clear specimens were prepared. The test materials were derived from three randomly chosen trees.

Leaf diffusion resistance pattern in an oak-hornbeam forest

open access: yesBiologia Plantarum, 1979
Four tree, five shrub, and ten herbaceous species growing naturally in an oak-hornbeam forest were used for simultaneous study of the leaf diffusive resistances in the course of several summer days. Absolute minima of the stomatal resistance in the sun tree, the shrub, and the herbaceous species leaves were 1.7 to 6.2 s cm-1, 6.1 to 10.8 s cm-1, and 4 ...
