The Pulsational Behaviour of Variable Stars in the Lower Part of the Instability Strip

The effect of convection on pulsational stability

A review on the current state of mode physics in classical pulsators is presented. Two, currently in use, time-dependent convection models are compared and their applications on mode stability are discussed with particular emphasis on the location of the Delta Scuti instability strip.

Errata The following corrections should be made to the text: 8, Page is defined as the lift coefficient acting on the complete system but due solely to the rotation of the fla u/?and This is given as the difference between the CL at a given value of the CL with flap fixed (P = 45O). However, this value of C LR still includes the effect of the flap acting as an ordinary flap on the wing through ...

On The Pulsational Stability of Blue Supergiants

The brightest blue supergiants represent the most massive evolved stars known. They are believed to be in the core helium-burning phase of evolution. To discuss the question of their stability, model interiors of core helium-burning stars with hydrogen-burning shells have been constructed and tested for pulsational instability (15-1000 M0). All models are found to be extremely stable against nu...

THE Jonma~ OF BIOLOGICAL CHEM~~RY

ATP has two significant effects on the mitochondrial tricarboxylate transporting system. First, it alters the concentration gradients at equilibrium for the substrates of this transporter. ATP (2 IDM) caused the uptake of 10 nmol of citrate into the mitochondria coincident with the output of a similar amount of L-malate. This redistribution was dependent on ATP transport, the effect being inhib...
