Effects of Mass Loss on Stellar Evolution: IAU Colloquium no. 59 Held in Miramare, Trieste, Italy, September 15–19, 1980

The IAU Colloquium No. fifty nine, "The results of mass loss on Stellar Evolution" was once hung on September 15-19, 1980 on the foreign Centre for Theoretical Physics, Miramare, Trieste (Italy), lower than the auspices of the IAU govt Co~ mittee and the Italian nationwide Council of study. The making plans of this convention started years in the past du­ ring the IAU Symposium No.

Cerebral Cortex: Neurodegenerative and Age-Related Changes in Structure and Function of Cerebral Cortex

This quantity of Cerebral Cortex is devoted to Sir John Eccles, who was once an lively member of the advisory board for the sequence till his dying in may possibly 1997. His enter as to what issues can be coated in destiny volumes of this sequence may be sorely ignored. the current quantity is anxious with neurodegenerative issues and age­ comparable adjustments within the constitution and serve as of the cerebral cortex, an issue that has attracted expanding curiosity as sturdiness and the variety of elderly participants within the inhabitants bring up.

Alcoholism and Drug Dependence: A Multidisciplinary Approach

It truly is for me, as President of the Merseyside Lancashire & Cheshire Council on Alcoholism, a sign privilege to put in writing a short foreword to those court cases of the 3rd foreign convention on Alcoholism and Drug Dependence. through the week specialists, from across the world, in all these disciplines that have a contribution to make to the answer of the issues of alcoholism and drug dependence, surveyed fresh advances in our wisdom of the aetiology, epidemiology, early acceptance, administration, and the social and commercial implications of those dual scourges of the modern scene.

Facing walls for obvious reasons. In temperate western Europe the best specimens of mural vegetation are found in Ireland, southern England and western France (more particularly Brittany and Normandy and the neighbourin~ old culture regions such as the towns and the castles in the Loire valley). The conditions are not so favourable in the Low Countries on account of the slightly more continental climate. Nevertheless some well-developed examples of wall vegetation occur farther inland in W. Germany and Switzerland in the more subatlantic parts, but they rapidly become rarer towards the East.

Grassy sites including meadows, hay-fields, roadsides, dikes, etc. and H ochstauden vegetation. a. Grassy sites. b. chstauden vegetation (generally on peaty soils). 8. Dwarf shrub vegetation, scrubs and forests. a. Heaths, moors, garigues and macchia. b. Scrubs. c. Forests. 9. Vegetation of contact zones and various other cases.

Polychory: dispersal not clearly restricted to only one of the other categories. Other types of dispersal (such as diszoochory) are presumably of little importance among the species occurring in vegetation of walls. The arrangement of the species in the spectra is principally based on the migration spectra. Blastochory, autochory and barochory are only indicated in those rare instances in which these forms of dissemination occur frequently in the biotopes studied. For many species, whose mode of dispersal has not, or at least not unequivocally, been established, the entry is: "dispersal unknown".
