Phérécyde de Syros D6/R23 (LM) réexaminé [PDF]
Philosophie antique, 2021 L’article reexamine la signification, dans la pensee de Pherecyde, du temoignage de Damascius sur la generation des dieux des cinq recoins par les trois elements crees par Chronos. Les modeles par lesquels on explique la generation de cinq familles de dieux ou de cinq regions du monde a partir de ces trois elements comportent des difficultes internes ...

Solid–Liquid Equilibria for the CO2 + R23 and N2O + R23 Systems [PDF]
International Journal of Thermophysics, 2008 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.

R23. Anonymus Franciscanus [PDF]
, 2007 This chapter presents a conversation between a narrator and an auditor. The central theme of the miracles is that they were caused by the Franciscans. The narrator joins the miracle stories to each other, without putting them against each other. The auditor interrupts him sometimes with questions that relate to the theological or doctrinal aspects of ...

Cascade Refrigeration System: R404a-R23 Refrigerant
Asian Journal of Electrical Sciences, 2017 This study is presented a cascade refrigeration system using as refrigerant (R23) in low-temperature circuit and R404a in high-temperature circuit. The operating parameters considered in this paper include superheating, condensing, evaporating, and sub cooling temperatures in the refrigerant (R404a) high temperature circuit and in the refrigerant (R23))

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 20 (H4K20me3).

Numerical Simulation Of R410A-R23 And R404A-R508B Cascade Refrigeration System
, 2010 Capacity and efficiency of any refrigerating system diminish rapidly as the difference between the evaporating and condensing temperature is increased by a reduction in the evaporator temperature. The single stage vapour compression refrigeration system using various refrigerants are limited to an evaporator temperature of -40 0C. Below temperature of -

Direct Te Metallicity Calibration of R23 in Strong Line Emitters [PDF]
The Astrophysical Journal, 2019 Abstract 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. Most calibrations for these strong-line metallicity indicators are for continuum selected galaxies. We report a
