The massic energy of combustion of vanadium disilicide in fluorine according to the reaction: VSi 2(cr) + (13/2)F 2(g) = VF 5(g) + 2SiF 4(g), has been measured
The minimum amounts or concentrations of an analyte that may be detected or quantified by a specific measurement process (MP) represent fundamental performance
Methyl 2,6-anhydro-3-deoxy-3-phthalimido-α-D-mannopyranoside and its 15N-labeled analog have been synthesized by reaction of methyl 2,6:3,4-dianhydro-α-D
We present a description and detailed error analysis of a polarization-mode dispersion measurement system which used the Jones matrix eigenanalysis measurement
A stack of quasi-randomly oriented quartz plates has been assembled as a calibration artifact for mode-coupled polarization-mode dispersion. The design of the
Fully relaxed, planewave pseudopotential calculations of total energies were performed for three ordered perovskite related supercells in each of the eight
Blind deconvolution seeks to deblur an image without knowing the cause of the blur. Iterative methods are commonly applied to that problem, but the iterative
Thermal conductivity measurements of a high-density glass-fiber thermal insulation material near 24 C are presented for the determination of the precision and
One difficulty in the field use of high performance concrete is the extensive self-desiccation and autogeneous shrinkage that may occur due to its lower w/c
I appreciate the comments of Mike Gruntman (Sept., page 80) concerning the history of using correlated pairs of particles(photons) to determine absolute

Biocatalysis using oxygenase or desaturase enzymes has the potential to add value to native fats and oils by adding oxygen hydroxyl groups, or double bonds to
The BEES (Building for Environmental and Economic Sustainability) software implements a rational, systematic technique for balancing the environmental and
The atomic force microscope (AFM) is used to generate images based on the interaction forces between the probe tip and the sample surface. These interaction
The gallium trip point (302.9166 K) instead of the gallium melting point (302.9146 K) is used at NIST in the realization of the International Temperature Scale
We describe a simple model for the temperature dependence of the exchange bias and related effects that result from coupling a ferromagnetic thin film to a
A new spatial correlation function is derived for the axial electric field and is compared with the previously known spatial correlation function for the total
Much has been written about embedded systems and how they will be affected by the year 2000 problem. During the first 6 months of 1999, a significant amount of
Reduction potentials of the SO- 3 -, SO 5 -, and S 4O 6 3- radicals in aqueous solutions are measured by pulse radiolysis at 294 K. These radicals are produced
The effect of pressure on the cross- radical reactions of vinyl and methyl radicals have been investigated. These radicals were produced by excimer laser
The energies of cyclobutyne, perfluorocyclobutyne and related compounds have been calculated at levels from MP2/6-31G* through QCISD(T)/6-311+G*, and also at

We have studied the time development of the molecular mass distribution (MWD) of living bifunctional poly(α-methylstyrene) in tetrahydrofuran after a quench to
The length-scale dependence of the dynamic entropy is studied in a molecular dynamics simulation of a binary Lennard-Jones liquid above the mode-coupling
