When leaving the Victoria airport the day earlier than our Colloquium, I observed a van of the Dunsmuir resort marked with monstrous letters which I learn as "Alcohol Colloquium". I do usually make such error due to the worldwide, informal, and careless manner within which I learn quite a few advertisements, and checked myself speedy to learn it accurately as "Algol Colloquium". hundreds of thousands of fellow electorate may simply make an identical mistake, and no apology might be anticipated. Even I learn and listen to the observe alcohol extra usually than Algol, even if i have to say that Algols have given me extra excitement and less complications through the years; in that, notwithstanding, i'll be a singularity, and probably a pitiful one at that. Being appointed Chairman of the medical Organizing Committee, i'll be deemed to be a purer" Algolist" than different investigators, even supposing my diversity of lively pursuits is far broader; and a similar is right approximately all of the 28 invited audio system and all of the different contributors of the Colloquium. Our curiosity are strongly diverse, yet there are a number of sturdy purposes that introduced us jointly at this Colloquium.

These disks do not have the classical alpha structure. They are optically thin normal to the orbital plane, but may be geometrically thicker than purely gravitationally-stratified disks. Disk gas may be contaminated by dust particles acquired from the outer layers of the cool loser. In some systems, 'high' states, produced by elevated mass accretion by the hot star, occur, suggesting that the mass distribution in the disk is clumpy. However mass-transfer rates are found, they lie between 10- 7 and 10- 6 solar masses per year.

Accretion disks in such binaries are thought to have the classical 'alpha' structure of Shakura and Sunyaev (1973), in which viscous dissipation arising from differential rotation converts gravitational potential energy to thermal energy in supplying the disk luminosity. This physical process requires that the viscous time scale be comparable to the radiative decay time of the disk (Pringle 1981). Most of the disk's volume is optically thick, so disk luminosity is estimated by integrating black-body or stellar atmospheric fluxes over the disk (see Kriz and Hubeny 1986 for qualifications).
