Tryptophan synthase, an alpha 2 beta 2 complex, is a classic example of an enzyme that is thought to "channel" a metabolic intermediate (indole) from the active site of the alpha subunit to the active site of the beta subunit. We now examine the kinetics of substrate channeling by tryptophan synthase directly by chemi…
Abstract An analysis of available methods of dealing with polymer crystallization for process modeling is presented. Problems encountered in using isothermal data to predict nonisothermal results are discussed and illustrated using experimental data for nylon 6. A half‐time analysis is used to evaluate and extrapolate…

Equations that described the thermodynamic properties of the NaBr+H2O system were obtained from a fit to experimental results for this system. The experimental results included in the fit spanned the range of temperature of approximately 260 to 623 K and the range of pressure from the vapor pressure of the solution to…
The phosphor has been investigated for its application to vacuum fluorescent displays (VFDs) utilizing low‐voltage cathodoluminescence. It is expected that this oxide phosphor does not cause damage to filaments in VFD's, while it is a serious problem for conventional sulfide phosphors. This phosphor shows blue lumines…
We have constructed the metallicity distribution of a sample of 372 kinematically selected halo stars, most having spectroscopically determined abundances, drawn from our southern subdwarf study and the northern program of Laird et al. [AJ, 95, 1843 (l988a); 96, 1908 (l988b)]. We find that the metallicity distribution…
The dynamic response of the electrons at the surface of simple metals, like Na, K and Cs, to an external time varying field is discussed in this paper. Of special interest are the normal modes at a surface, defined theoretically by the poles in the reflection function. The surface plasmon is the best known normal mode…

Molecular mechanics calculations, based on a force field derived from a previously published normal coordinate analysis for NiOEP (1) and the X-ray structure of NiOEP? triclinic form, have been used to predict the structures of NiTPP (2), NiP (3), and several recently synthesized nickel porphyrins which bear alkyl or…
This is a review paper on the history of ferroelectric thin films, current practices in their fabrication, characteristics of interest which relate to their use, and the application of these films to memory and electrooptic devices.
