The study of thermodynamic properties of zeotropic mixtures of R600a/R23/R14 [PDF]
Advances in Mechanical Engineering, 2017 Thermodynamic properties of zeotropic mixtures of R600a/R23/R14 have been investigated and calculated based on the established mathematical model. The deviations of bubble pressure and vapor composition between the simulation results and the experimental

Phérécyde de Syros D6/R23 (LM) réexaminé
Philosophie antique, 2021 L’article réexamine la signification, dans la pensée de Phérécyde, du témoignage de Damascius sur la génération des dieux des cinq recoins par les trois éléments créés par Chronos. Les modèles par lesquels on explique la génération de cinq familles de dieux ou de cinq régions du monde à partir de ces trois éléments comportent des difficultés internes ...

Spindlin‐1 recognizes methylations of K20 and R23 of histone H4 tail [PDF]
FEBS Letters, 2018 Using methods combining cross‐linking, pull‐down assays, and stable isotope labeling by amino acids in cell culture with mass spectrometry, we identified that the Tudor domain‐containing protein Spindlin‐1 recognizes trimethylation of histone H4 lysine ...

Direct Te Metallicity Calibration of R23 in Strong Line Emitters [PDF]
The Astrophysical Journal, 2018 The gas metallicity of galaxies is often estimated using strong emission lines such as the optical lines of [O iii] and [O ii]. The most common measure is “R23,” defined as ([O ii]λλ3726, 3729 + [O iii]λλ4959,5007)/Hβ.

Solid–Liquid Equilibria for the CO2 + R23 and N2O + R23 Systems [PDF]
International Journal of Thermophysics, 2009 A recently built experimental setup was employed for the estimation of the solid-liquid equilibria of alternative refrigerant systems. In this paper two binaries, i.e., carbon dioxide + trifluoromethane (CO2 + R23) and nitrous oxide + trifluoromethane (N2O + R23), were studied down to temperatures of 117 K.

Enthalpy-composition Diagram Plotting for R134a/R23
Zhileng xuebao, 2005 R134a/R23 is a new refrigerant mixture and friendly to environment. In this research, the vapor-liquid equilibrium, enthalpy, and entropy of this mixture were calculated based on Peng-Robinson(PR)equation of state(EOS). To make PR equation more accurate,
