Effect Of Altitude And Aspect On Various Wood Properties Oforiental Beech (Fagus Orientalis Lipsky) Wood, Eli̇f Topaloğlu, Nurgül Ay, Lokman Altun, Bedri̇ Serdar Jan 2016

Effect Of Altitude And Aspect On Various Wood Properties Oforiental Beech (Fagus Orientalis Lipsky) Wood, Eli̇f Topaloğlu, Nurgül Ay, Lokman Altun, Bedri̇ Serdar

Turkish Journal of Agriculture and Forestry

In this study it was proposed to investigate the effect of altitude and aspect on anatomical properties, wood density, and mechanical properties of Oriental beech (Fagus orientalis Lipsky) growing in Sinop, Turkey. Five altitude steps (0-200, 200-400, 400-600, 600-800, and 800-1000 m) and two aspect groups (north and south) were created in the research area. A total of 20 trees were cut from each altitude step and the north and south aspects. To determine the anatomical properties of wood, permanent slides were prepared and Schultze's method was used for measurement of fibers. Wood density and mechanical properties were examined according …


Nondestructive Determination Of Spruce Lumber Wood Density Using Drilling Resistance (Resistograph) Method, Bi̇lgi̇n İçel, Gürcan Güler Jan 2016

Nondestructive Determination Of Spruce Lumber Wood Density Using Drilling Resistance (Resistograph) Method, Bi̇lgi̇n İçel, Gürcan Güler

Turkish Journal of Agriculture and Forestry

The use of Resistograph for the purpose of nondestructive evaluation of certain properties of standing trees and wooden materials has increased in recent years. The resistance to penetration of a fine drill bit is measured and recorded by the device. A number of properties of the wood can be assessed by the amplitude values obtained from the Resistograph. The aim of this study was to assess the utility of the IML-Resistograph F 500 as a nondestructive tool for estimating spruce wood density using the amplitude data generated and the application of statistical modeling. Wood density data were determined using a …


The Effect Of Growth Conditions In Specific Areas Of Croatia And The Czech Republic On The Physical And Mechanical Properties Of Black Alder Wood (Alnus Glutinosa Gaertn.), Jaromir Milch, Hanus Vavrcik, Jan Tippner, Martin Brabec Jan 2016

The Effect Of Growth Conditions In Specific Areas Of Croatia And The Czech Republic On The Physical And Mechanical Properties Of Black Alder Wood (Alnus Glutinosa Gaertn.), Jaromir Milch, Hanus Vavrcik, Jan Tippner, Martin Brabec

Turkish Journal of Agriculture and Forestry

In this paper, static bending (modulus of rupture, MOR, and modulus of elasticity, MOE) and compression strength parallel to grain (Σc??) of black alder wood (Alnus glutinosa Gaertn.) were investigated. For experimental testing, we used black alder wood from two different areas: Crni Jarci, Croatia, and Malá Byst?ice, Czech Republic. Experimental tests were carried out according to the Czech national standards: ?SN 49 0115 and ?SN 49 0116 for static bending and ?SN 49 0110 for compression strength. The samples from Malá Byst?ice showed lower values of MOR (~14%), MOE (~30%), and Σc?? (~4%), when compared to the samples from …
