J. F. Lancasterluminosity is close to the Eddington-limit. The subsequent decline illustrates the interaction between radiation and matter in a wind which gradually thins as the mass loss rate falls at an approximately constant Eddington-limit luminosity. As the wind thins so the effective photosphere shrinks back

J. F. Lancasters of active silicon (Si), and normally the bottom Si layer is a mere physical structure. The idea of making intelligent pixel detectors by using the bottom Si layer as sensors for X-ray, infrared light, high-energy particles, neutrons, etc. emerged from very early days of the SOI technology. However

Carbon and ferritic-alloy steels,groups that are used in welded fabrication. Cast iron is included in the material groups since, from a welding viewpoint, it suffers the same type of transformation in the HAZ of fusion welds as steel, albeit in an extreme form.

Non-ferrous metals,lectrode-positive half-cycle the oxide film is removed while during the electrode-negative half-cycle the workpiece is heated. However, d.c. electrode-positive may be used for special purposes. Welds may also be made with d.c. electrode-negative using helium as the shielding gas, but this too is for

ursts actually achieve super-Eddington luminosities, and if so, how? (c) What are the characteristics of quasi-static mass loss in the presence of such luminosities? (d) How is the color temperature related to the effective temperature? and, (e) What are the implications concerning the Galactic dist

J. F. Lancasterbeen discovered many years before their associated jet. Thus, both phenomena are highly related and in both cases the emission lines are very probably formed in the cooling regions of shock waves with velocities of 50–100 km/s. There are a variety of mechanisms, which can in principal excite interna

J. F. Lancasterum plane-parallel hydrostatic neutrino atmospheres. The second is to solve the equations of neutrino hydrodynamics for a spherical shell of matter, with a piston and a source of neutrinos at the lower boundary. We describe in detail the neutrino interactions which are important in the supernova prob
