✦ Synopsis

Abstract

The correlation of TEM imaging and micro‐photoluminescence studies of electron irradiated areas of diamond, developed in Bristol, has been extended to new optical centres and defects. In this paper, we show new evidence of the interaction of point defects with dislocations and grain boundaries in diamond. Optical centres at 518.6 and 518.8 nm are directly correlated with dislocations and an optical centre at 519.1 nm was correlated with a grain boundary. (© 2005 WILEY‐VCH Verlag GmbH & Co.

We demonstrate that strained GeSi/Si heterostructures act as a model system for the study of the interaction of propagating dislocations with point, line and planar defects. In such heterostructures, the effective stress acting on a propagating dislocation may be varied from tens of MPa to of order

The new, extremely potent and enantioselective D-2 agonist LY 163502 failed to induce compulsive stereotyped behaviour. Very low doses (3-6 gg/kg) inhibited spontaneous sniffing and locomotion, while higher doses (12-50 gg/kg)induced episodes of non-stereotyped sniffing and chewing; these actions sh
