Virial Coefficients from Burnett Measurements for the R23 + N2O System

International Journal of Thermophysics, 2006
This paper presents experimental results for the trifluoromethane (R23) + nitrous oxide (N2O) system, which has been chosen as a working fluid for low-temperature applications since it might be a valid option for the low-temperature stage in a cascade cycle.

Reversal of inhibition of membrane-bound RNA synthesis in Escherichia coli infected with R23

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1973
Abstract 1. Infection by RNA bacteriophage R23 causes a release of ribosomes from a membrane-DNA-RNA polymerase complex isolated from Escherichia coli. This release may be responsible for the reduction in RNA synthetic capacity seen after phage infection. 2. The addition of ribosomes to such a membrane preparation restores the RNA synthetic capacity

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))

Expression of the lac operon in Escherichia coli infected with RNA phage R23

Canadian Journal of Microbiology, 1970
Infection of Escherichia coli by R23 results in a coordinate repression of permease and β-galactosidase genes of the lactose operon but this effect is not mediated at the level of the regulatory or promoter genes. Immediately preceding the inhibitory phase there is a transient phase of increased inducer uptake and enzyme synthesis which may be ...

Derived thermodynamic design data for heat pump systems operating on R23

Heat Recovery Systems and CHP, 1991
Abstract Theoretical Rankine coefficients of performance and the compression ratios have been presented for heat pump systems operating on R23. These values are listed in tabular form for temperature lifts of 5–75°C and condensing temperatures of 5–24°C in one degree increments.

The ribosomal-RNA synthesis factor ψr in Escherichia coli infected with RNA bacteriophage R23

Biochemical and Biophysical Research Communications, 1971
Infection of Escherichia coli with the RNA bacteriophage R23 inhibits RNA synthesis by the cell membrane-DNA-RNA polymerase complex of the host cell, and this inhibition cannot be reversed by the addition of ψr to the reaction mixture. Infection of E. coli with R23 does not cause a decrease in the level of the factor ψr present in the cell supernatant.

Effect of infection with R23 on DNA and RNA synthesis in Escherichia coli

Canadian Journal of Microbiology, 1971
Infection of Escherichia coli by R23 results in a marked inhibition of rRNA synthesis. Both 16 S and 23 S RNA are inhibited with maximal inhibition occurring at 30 min. Inhibition of 4 S RNA is not as profound. DNA synthesis is also inhibited after R23 infection although infected cells continue to divide for about one generation (45–60 min) after ...
