Rhenium in seawater: Confirmation of generally conservative behavior
A depth profile ofthe con~ntration of Re was measured in the Pacific Ocean using a technique we have developed for the clean chemical separation and the precise measurement of Re by isotope dilution and negative thermal ionization mass spectrometry (ID-NTIMS). This technique permits Re concentrations to be determined from 200 mL of seawater with a typical precision of +5%0. This is an improveme...
متن کاملGenerally Covariant Conservative Energy-Momentum for Gravitational Anyons
We obtain a generally covariant conservation law of energy momentum for gravitational anyons by the general displacement transform. The energymomentum currents have also superpotentials and are therefore identically conserved. It is shown that for Deser’s solution and Clément’s solution, the energy vanishes. The reasonableness of the definition of energy-momentum may be confirmed by the solutio...
متن کاملDynamic Enthalpy, Conservative Temperature, and the Seawater Boussinesq Approximation
A new seawater Boussinesq system is introduced, and it is shown that this approximation to the equations of motion of a compressible binary solution has an energy conservation law that is a consistent approximation to the Bernoulli equation of the full system. The seawater Boussinesq approximation simplifies the mass conservation equation to $ u 5 0, employs the nonlinear equation of state of s...

15 صفحه اولDichroic Electro-Optical Behavior of Rhenium Sulfide Layered Crystal
Dichroic behaviors of layered ReS2 have been characterized using angular dependent polarized-absorption and resistivity measurements in the van der Waal plane. The angular dependent optical and electrical measurements are carried out with angles ranging from = 0 ̊ (E || b) to = 90 ̊ (E b) with respect to the layer crystal’s b-axis. The angular dependence of polarized energy gaps of ReS2 sho...
