The aim of this study was to investigate the effects of thermally compressed veneer laminating on some of the physical and mechanical properties of particleboard. Oriental beech (Fagus orientalis Lipsky) veneers were compressed under various press conditions. Commercially produced particleboard samples were laminated with such compressed veneer sheets. The density, 2-h and 24-h water absorption...
The goal is to protect semi-finished/finished wood components from burning/fires in a variety of settings (wooden buildings, historical sites, restoration, etc.). Natural (organic) sea mussel shells (Chamelea gallina) were crushed and prepared with water various solution concentrations (10%, 15%) after the pyrolysis process, either alone or together boron compounds (borax). limiting oxygen inde...
In this study, investigation of the combustion properties Oriental beech wood (Fagus orientalis Lipsky) impregnated with boron compound (borax (Na2B4O710H2O), boric acid (H3BO3) doped rosin (C19H29COOH) was aimed. For purpose, samples were prepared according to ASTM E 160-50 and by method medium-term dipping (24 hours) D 1413 producers’ definition. Combustion after process determined 160-50. As...
Bu çalışmada, bazı antibakteriyel nano malzeme katkılı verniklerin ahşap malzemede katman sertliğine etkisi araştırılmıştır. Sarıçam (Pinus sylvestris L), Doğu kayını (Fagus orientalis Lipsky), sapsız meşeden (Quercus petraea Liebl.) hazırlanan örneklere, %0,1, %0,3 bor (NaB) ve gümüş (NaAg) ilave edilmiş su bazlı sentetik vernik ile ASTM D-3023’e göre verniklenmiştir. Vernikleme işleminden son...
Resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. To observe how differences in forest management affect the genetic structure of Fagus orientalis Lipsky (oriental beech), we evaluated thirteen beech sites across Hyrcanian forests, based on six microsatellite loci. Significant di...
Information about gaps and their sizes distribution is useful for protecting herbaceous diversity. This study was conducted to investigate the effect of gap size on herbaceous species diversity in oriental beech (Fagus orientalis Lipsky.) stand in Asalem, Guilan province. For this study, fifteen gaps in small, medium, and large sizes were randomly selected. Then, herbaceous species were ident...
