Experiments on the performance of bubble pumps with R134a/R23-DMF solutions for diffusion absorption refrigerator

, 2020
Experiments on the performance of a bubble pump for diffusion absorption refrigerator with different lifting tubes (diameter of 8 mm and 10 mm), different filling compositions of R134a/R23 (35%/0%, 33.5%/4%, 32.2%/8%, and 30.8%/12%) and different heads ...

Isochoric measurements of the R23 + CO2 binary system

Fluid Phase Equilibria, 2003
Abstract Isochoric measurements were taken for the R23+CO 2 system for both the two-phase and the superheated vapor regions. The isochoric experiment covered a temperature range from 253 to 353 K and a pressure range from 1590 to 5880 kPa. The data in the two-phase region enabled VLE parameters to be derived using a flash method with the Carnahan ...

Nonanalytical unified equation of state of freezant R23

Journal of Engineering Physics and Thermophysics, 1994
A unified equation of state of freezant R23 is obtained that adequately describes a thermodynamic surface both in the region of low densities and pressures and in the vicinity of a critical point.

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 ...

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 ...
