Terrestrial laser scanning (TLS) has been applied to estimate forest wood volume based on detailed 3D tree reconstructions from point cloud data. However, sources of uncertainties in the data (alignment and scattering errors, occlusion, foliage...) reconstruction algorithm type parameterisation are known affect reconstruction, especially around finer branches. To better understand impacts...

This paper presents the results of monitoring behaviour selected wood species exposed to a small ignition initiator. We specifically aimed investigate effect retardant coating on combustion process spruce (Picea abies), red (Larix decidua), Scots pine (Pinus sylvestris), ash (Fraxinus excelsior L.), beech (Fagus sylvatica), and oak (Quercus robur) when initiator ignition. At same time, we studi...

Nuzhenide and GI3, the principal secoiridoids of an extract obtained from the seeds of Fraxinus excelsior L. (FXE), are believed to be the active compounds responsible for the previously reported hypoglycemic effects of this extract. In this study, the effects of FXE were studied in two animal models which are representative of metabolic disorders: spontaneously hypertensive rats (SHR) and obes...

Cambial injury has been reported to alter wood structure in broad-leaved trees. However, the duration and extension of associated anatomical changes have rarely been analysed thoroughly. A total of 18 young European ash (Fraxinus excelsior L.) trees injured on the stem by a spring flood were sampled with the aim of comparing earlywood vessels and rays formed prior to and after the scarring even...

In this study is to examine the effect of industrial heat treatment application on dimensional stability and dynamic wettability properties ash (Fraxinus excelsior) wood. Ash samples that were treated for 120 minutes at 210 degrees according ThermoWood process used. study, a total 30 samples, including 15 with dimensions 20x20x30 mm, unheat cut examined. The results obtained in showed property ...

The wood of five European species: black poplar (Populus nigra L.), beech (Fagus sylvatica ash (Fraxinus excelsior oak (Quercus robur and Scots pine (Pinus sylvestris L.) was subjected to thermal modification in nitrogen atmosphere at 190 °C during 6 h. Native modified varnished oiled industrial conditions. Thermally (TM) characterized by a greater absorption varnish oil when applying the first...
