The effects which alterations in the concentrations of internal sodium and high energy phosphate compounds had on the sodium influx and efflux of internally dialyzed squid axons were examined. Nine naturally occurring high energy phosphate compounds were ineffective in supporting significant sodium extrusion. These compounds were: AcP, PEP, G-3-P, ADP, AMP, GTP, CTP, PA, and UTP.(1) the compoun...

Using density functional theory, we have performed structural relaxations of Rh (111) and Cu (100). To obtain accurate results, these calculations must be converged with respect to all computational approximations. In particular, it is vital to treat Brillouin zone integration with care, taking into account the effect of finite k-point sampling on surface and bulk structural properties. A new m...

A treatment of internally constrained mixtures of elastic continua at a common temperature is de­ veloped. Internal constraints involving the defonnation gradient tensors and the common mixture temperature are represented by a constraint manifold, and an internally constrained mixture ofelastic continua is associated with each unique equivalence class ofunconstrained mixtures. The example of in...
