Pressure effects on Ca60Al40 metallic glass superconductors
Theoretical computation of the pressure dependence superconducting state parameters of binary Ca60Al40 is reported using model potential formalism. Explicit expressions have been derived for the volume dependence of the electron–phonon coupling strength λ and the Coulomb pseudopotential μ* considering the variation of Fermi momentum KF and Debye temperature ӨD with volume. Well known Ashcroft’s...
متن کاملThe Reduction of Uncertainties for Absolute Piston Gage Pressure Measurements in the Atmospheric Pressure Range
NIST pressure calibration services with nitrogen are now based on two transfer standard piston gages for which the effective areas have been determined by calibration with the manometer developed at NIST for gas thermometry. Root-sum-squared three sigma uncertainties for the areas for the two gages are 3.05 ppm and 4.18 ppm.
متن کاملQnAs with Fred Gage.
With the advent of rapid genome sequencing, the view of the human genome as a vast desert dotted with far-flung oases of functional genes has contended with a growing appreciation of the role of regulatory sequences in shaping gene expression. The fraction of the human genome’s noncoding component that can be considered functional remains to be established, but strewn across the seeming wastela...
متن کاملMiniature all-glass robust pressure sensor.
This paper describes a newly designed all-glass miniature (Ø 125 microm) fiber-optic pressure sensor design that is appropriate for high-volume manufacturing. The fabrication process is based on the chemical etching of specially-designed silica optical fiber, and involves a low number of critical production operations. The presented sensor design can be used with either single-mode or multi-mod...
متن کاملEstimating intraocular pressure using a glass rod.
Four masked examiners studied the usefulness of the glass-rod for estimating intraocular pressure (IOP) in a living, anesthetized rabbit eye manometrically set to 135 different random values. With training, the average error in IOP estimation improved from 7.42 +/- 5.56 mmHg to 5.13 +/- 4.48 mmHg. Gentle palpation of the corneal apex with a glass-rod provides tactile and visual clues that may a...
