Discs gone with the wind?
We examine the conditions imposed on the vertical structure of accretion discs for them to exist. We find that a wind powered by a thermal instability exists in all discs with certain opacity laws. We find that for discs dominated by bremsstrahlung radiation, an inner hole develops below a certain accretion rate, and that for very low accretion rates, discs may not form at all. The consequences...
متن کاملGone, gone and going
Biomedicine swallows the lion's share of life science funding but there is mounting concern that the health of ecosystems should be demanding more attention. Nigel Williams reports.
متن کاملInflammation: Gone with Translation
Inflammation (derived from the Latin inflammo, which means ‘‘I set alight’’) is a beneficial response of our immune system that protects us against infection and tissue injury. Like all immune responses, it needs to be tightly controlled: excessive inflammatory responses can lead to both acute diseases, such as septic shock, and chronic diseases, such as rheumatoid arthritis, atherosclerosis, a...
متن کاملEvaluation of Composite Vane Materials for Rotary Sliding Vane Compressors
The physical performance characteristics of composite materials used for vanes in rotary, sliding-vane compressors, in general, are several orders of magnitude more difficult to quantify for design purposes than most homogeneous materials. This arises from the numerous variables that influence the response of these materials under the severe environmental conditions existing in such compressors...
متن کاملVane Dynamics Analysis of a Tilted Vane Rotary Compressor
An analytical model of vane dynamics in a tilted vane rotary compressor is presented. With the geometric relationship of the vane in a tilted slot, and the roller, the kinetic equations were derived for evaluating the reciprocating inertial force of the vane, and the chamber volume equations were obtained for calculating pressure history inside the compression chamber. The empirical friction co...
