Effects of drying temperature and artificial UV irradiation on the pH of veneer surfaces, water absorption, thickness swelling, as well as shear strength of plywood manufactured from untreated and treated veneer sheets were evaluated. Rotary cut veneer sheets from beech (Fagus orientalis Lipsky) log were selected. The veneer sheets were dried at either 100C or 180C after peeling. Then the sur...
Bu çalışmanın amacı; kayın ağaçlarının yetiştiği ortamlardaki bazı ekosistem değişkenleriyle odunun fiziksel ve mekanik özelliklerinin nasıl değiştiğini ortaya koymaktır. Araştırma sahaları, Batı Karadeniz meşcerelerinden belirlenmiştir. Çalışma için kayının yayıldığı alt rakımdan üst rakıma kadar farklı yükselti bakılardan 6 saha seçilmiştir. altı sahanın her birinde sahayı temsil edecek 100 m...
In this study the impact of production work on the skid roads that have been carried out for many years by manpower animal power or machinery in a beech (Fagus orientalis Lipsky) stand have been examined. For this purpose, herbaceous understory, forest floor and soil samples were collected from the undisturbed area and the skid road. Weight per unit area (kg ha(-1)), organic matter ratio and mo...
The effects of soil pedoturbation (i.e., pit and mound microtopography, PM) on development of herbaceous plant species and woody species regeneration were examined in a temperate beech forest (Fagus orientalis Lipsky) in northern Iran. We recorded the vegetation in 20 pairs of disturbed and adjacent undisturbed plots and established a chronosequence of PM ages to study the effect of time since ...
Moisture content (MC) is one of the most important factors that can affect many physical and mechanical properties of wood and veneers. MC strongly affects the final strength and durability of joints, development of surface checks in the wood and dimensional stability of the bonded assembly. In this study, plywood panels made from Alnus glutinosa (Alder), Fagus orientalis (Beech) and Picea orie...
