Mass spectrometric investigation of Alkyl-Substituted arylpyridynes

May 1, 1980
Author(s)
Anzor Mikaia, Anatolyi Soldatenkov, Vadim Fedorov, Vladimir G. Zaikin, Nikolay A. Prostakov
Electron ionization decomposition of aryl(polyalkyl)pyridines containing is studied. General fragmentation pathways and specific patterns for 2-. 3- and 4-arylsubstituted are identified

System for Fire Safety Evaluation of Health Care Facilities.

May 1, 1980
Author(s)
Harold E. Nelson, A J. Shibe
A quantitative evaluation system for grading health care facilities in terms of fire safety is described. The system can be used to determine how combinations of widely accepted fire safety equipment and building construction features may provide a level

Vacuum-ultraviolet spectral-irradiance calibrations: method and applications

May 1, 1980
Author(s)
William R. Ott, John M. Bridges, J Klose
A method to determine the spectral irradiance of a radiation source in the vacuum ultraviolet through the use of recently developed spectral-radiance standards is described. The method has been applied between 138 and 310 nm, and the spectral irradiances

Numerical Analysis of Doubly Rotated Cut SAW Devices

April 30, 1980
Author(s)
Dylan Williams, F Y. Cho
Results of a numerical study of the properties of surface acoustic waves (SAW) on doubly rotated cuts of alpha quartz are presented. First and second order TCF's have been calculated on a 10° x 10° x 10° grid spanning the range of angles (XY wlt) 0 to 3O°/

GaAs Spin Polarized Electron Source

April 1, 1980
Author(s)
Daniel T. Pierce, Robert Celotta, G Wang, W Unertl, A Galejs, C Kuyatt, S Mielczarek
The design, construction, operation, and performance of a spin polarized electron source utilizing photoemission from negative electron affinity (NEA) GaAs are presented in detail. A polarization of 43plus or minus}2% is produced using NEA GaAs (100). The

An Interface Phase Transition: Complete to Partial Wetting

March 7, 1980
Author(s)
Michael Moldover, John W. Cahn
When two fluid phases are near a critical point, one of them will be excluded from contact with any third phase that happens to be present by a wetting film of the other critical phase. A simple and quite general strategy that may be used to induce a phase

Ising Models for Order-Disorder Transition in an Adsorbed Overlayer

March 2, 1980
Author(s)
T M. Lu
Based on a 2D zero field anti-ferromagnetic Ising model, we obtain a relation between the angular distribution of intensity of a LEED superlattice beam from an adsorbed lattice gas with nearest-neighbor repulsive interaction and the spin-spin correlation
