Summary Growth models are developed for unthinned stands of radiata pine in the south-east of South Australia using data from the Permanent Sample Plots maintained over many years by the Woods and Forests Department, now Forestry SA. The data base is

Summary An alternative to the use of contingency allowances is described. It enables the level of cut to be set at the level that forest planners predict is appropriate, while explicitly allowing for the imprecision of the estimates.

Summary The evolution of growth and yield models for South Austral-ian radiata pine plantations is traced from the first yield table developed by H.R. Gray in 1931 to the most recently devel-oped growth functions. The adoption of new technologies is

Summary Line intersect sampling is applied in various aspects of forest management. One of the more common applications is to estimate the quantity of logging residue remaining on the ground following harvesting operations. The estimate of residue qu

Stable lattice dynamical models of orthorhombic C2H2 are developed from those devised by Hirshfeld and Mirsky (1979) for the cubic phase. These satisfactorily reproduce measured phonon frequencies but cannot account for the crystal cohesive energy. M

Summary Rotation length in plantation forestry cannot be determined simply on economic or volume criteria alone, or on single stand or forest based analyses. The determination of rotation length should be based on a number of separate analyses which

Lattice dynamics calculations on crystalline cyanogen, C2N2, are reported. Lennard-Jones 12-6 potentials are used to represent the three types of atom-atom interactions N-N, C-C and C-N. Variation of six parameters involved and slight adjustment of t

The frequencies of selected intermolecular modes of vibration and libration in a single crystal of deuterated ammonia (ND3) have been measured by the technique of coherent inelastic neutron scattering, at temperatures of 20 and 95 K. The results are
