Generalized Ramsey numbers for paths in 2-chromatic graphs

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
Chung and Liu have defined the d-chromatic Ramsey number as follows. Let 1≤d≤c and let t=(cd). Let 1,2,…,t be the ordered subsets of d colors chosen from c distinct colors. Let G1,G2,…,Gt be graphs. The d-chromatic Ramsey number denoted by rdc(G1,G2,…,Gt)

Membrane-bound Ribonucleic Acid Synthesis in Escherichia coli Infected with Ribonucleic Acid Bacteriophage R23

open access: yesJournal of Biological Chemistry, 1971
Abstract 1. A cell membrane-DNA-RNA polymerase complex which contains virtually all of the RNA-synthetic capacity of the cell has been isolated from uninfected and R23-infected Escherichia coli. 2. Infection of E. coli by RNA bacteriophage R23 inhibits the RNA synthetic capacity of the membrane complex.

Numerical Simulation Of R410A-R23 And R404A-R508B Cascade Refrigeration System

open access: yes, 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 -
