Transition in viscoelastic properties within successive annual rings of radiata pine (Pinus radiata)
Dynamic mechanical analysis (DMA) measurements of water-saturated radiata pine wood in the temperature range from 0 ℃ to 100 ℃ were focused to clarify the transition in viscoelastic properties within successive annual rings.

Modeling the forming surfaces of wood trunks using spline functions
It was developed the methodology for modeling complex geometric surfaces of natural origin – a tree trunk using spline functions. It allows to increase the accuracy and reliability of wood assessment in different dimensional characteristics, as well as ...

Pointer years in the growth of beech trees of the NP "Đerdap" area [PDF]
This paper defines pointer years and years with distinctive tree rings in the growth of beech in 3 sites (ecological units-EU) of the area of Đerdap, in order to observe the reactions of trees to the effects of various factors of growth.

The use of X-ray method to study annual growth variation of Pinus eldarica [PDF]
Using non-destructive methods to study forest productivity and wood quality as well as annual growth variations deserve special importance. In this regard annual growth changes of Pinus eldarica include width of the spring and summer rings and percentage
