✦ Synopsis

Summmy. Using the assumptions made on growth-stress related paramertexs in Pm't I, several optimization problems are posed. Finite element and optimization techniques show that for axisymmetric geometries, while cracking_ may be reduced by making cuts of special shapes , a compensating amount of wood is destroyed by making the cut. Also included in this study are banding of the log and stepped cuts with application of radial pressure. The results show that some combinations of radial pressure and the extent over which it is applied remove the most highly stressed wood.

Effects of the position and timing of cutting on shoot growth of young Crataegus monogyna plants in newly-planted hedges were studied. Total shoot length was unaffected by cutting. In general, a combination of both vertical and horizontal cutting produced a tall hedge with long, bud-tipped shoots. T

## Abstract Samples of laser‐scratched FeSi3 transformer sheets have been investigated. The investigations were carried out by using the Kossel and EBSD techniques in our self‐designed multifunctional system. The results show residual stress mappings of the cut edges of FeSi3 transformer sheets and
