Roles of PCNA-binding and ubiquitin-binding domains in human DNA polymerase in translesion DNA synthesis Investigations on the corrosive behaviour of Alloy 33 were conducted in 93% and 95-99% technical sulfuric acid at temperatures of 70-200℃. 6-h-tests with ... N.,Acharya,J.-H.,... ...
The oxidizing agent is chosen from a group comprising persulphate, perchlorate, permanganate and bichromate. The acid is chosen from a group comprising nitric acid, orthophosphoric acid and sulfuric acid. The gaseous carbondioxide traverses a trap to retain halogens and/or tritium.TORMOS JOSE...
Inclusion of heterogeneous kinetics involving the formation of nitric and sulfuric acid due to water condensation on soot particles showed that 15 percnet of the available NO_4 is converted into its inactive form but has a negligible effect on O_3 concentration. This method also provides ...
