The problem of dynamic symmetric branching of a tensile crack propagating in a brittle material is studied within Linear Elastic Fracture Mechanics theory. The Griffith energy criterion and the principle of local symmetry ...

The purpose of this study was to construct a model for the architecture of branches in Pinus radiata D. Don and to use it as a part of a modelling effort to relate timber quality as a function of growth and development. ...

Given a branched covering of degree d between closed surfaces, it determines a collection of partitions of d, the branch data. In this work we show that any branch data are realized by an indecomposable primitive branched ...

Perforated ray cells (PRCs) are recorded here for the first time in the roots and branches of Schefflera vinosa, Caryocar brasiliense, Acosmium subelegans, Byrsonima basiloba, B. coccolobifolia, B. verbascifolia and Alibertia ...

A destructive sampling method to estimate the age of first-order branches is presented. The proposed method can be applied only to living tree species showing annual growth rings. The implementation requires an estimate ...
