The dynamic tree stability assessment technique allows trees to be measured efficiently, under realistic weather conditions. In this study, the stability of four trees, including two conifers and two broad-leaved species was assessed in the Botanical

Red heart is one of the most important visual defects in beech wood. Its detection is difficult, since its mechanical characteristics do not differ significantly from sound wood. However, its electric conductivity is different, which offers an opport

A bükkfa egyik legjelentősebb esztétikai hibája az álgeszt, melynek elektromos tulajdonságai is eltérnek az egészséges faanyagétól. Ez lehetőséget kínál az álgeszt elektromos ellenállás mérésen alapuló vizsgálatára. Az álgeszt

In this study we present the Fourier transform (FT) of the absolute amplitude spectrum for direct application to wood anatomy. In spite of its simplicity, to our knowledge there is no reference in the literature regarding the use of repeated FT of an

Gamma irradiation is a simple and effective method to sterilize wood and stop fungal decay. Unfortunately, little is known of the effect of this method on other properties of wood. The purpose of the present study was to establish the relationship be

The pioneering studies on non-destructive testing (NDT) and evaluation (NDE) of wood have been introduced in early 20th century in Europe as it is in North America. Several improvements were recorded since then in NDT&NDE technologies with parallel t

A faanyag átvétele során visszatérő probléma, hogy a teherautókon szállított tűzifának illetve rostfának csak a tömegét tudják gyorsan és pontosan megmérni, a felhasználót viszont a szárazanyag-tartalom érdekli, az alapján kív

Shear modulus determination of construction size timber was examined. Three different Techniques were used: torsional vibration, simultan E&G, and variation of span technique. We found that the simultan E&G technique is quite sensitive to the error o

Bending and tensile strength of 2 by 4 lumber was estimated by one parameter and multiple parameter regression analyses. The strength predictors evaluated include static and dynamic modulus of elasticity (MOE), shear modulus, density, velocity, screw

The non-destructive testing (NDT) of timber using the longitudinal vibration method is based on the natural frequency of wood which is in relation to its quality. In the present paper, the suitability of this tool is investigated and the results of g
