A system for compatible prediction of total and merchantable volumes allowing for different definitions of tree volume Article in Canadian Journal of Forest Research 40(4) April A new computerized system is developed that has many desirable features for tree profile prediction.

This new system consists of two mathematical functions, one describing the upper bole and the A compatible system consisting of stem taper, merchantable- stem- branch- and stem and coarse branch tree volume equations was developed for 11 major tropical species in southeast :// The objective of this study is to develop a practical system for determining optimal bucking patterns at the stump.

The log bucking system was developed for implementation on an IBM-PC micro-computer using data for western hemlock (Tsuga heterophylla (Raf.) Sarg.).

The log bucking system is based on a two-phase optimization algorithm which utilizes dynamic programming-to determine the optimal Compatible taper and volume equations give identical estimates of total volume of trees. Two basically opposite techniques for the construction of compatible systems of estimating tree taper (decrease in diameter with increase in height) and volume were derived and examined statistically.

In the first method compatible taper equations are derived from volume equations fitted on tree volume   Abstract. Direct measurement of the wood volume in a tree stem is a difficult and time-consuming process, particularly if the tree is standing.

For many forest species around the world, functions have been developed that allow estimation of the volume in all of the stem or that much of it which is large enough to be :// Stem profile equations for southern tree species.

Cryptococcus gattii is a basidiomycetous yeast, which grows mainly as an asexual budding yeast in the environment and within human and animal hosts. Sexual reproduction can occur between cells of the opposite mating type or of the same mating type ().During sexual development, yeast cells undergo a dimorphic transition to hyphal growth, generating a mycelium and forming Christopher Bollyn is a well-travelled writer and an investigative journalist who has done extensive research into the events of Septemthe conflict in Middle-East and the health effects caused by exposure to depleted :// Scots pine is the main forest-forming species in Poland.
