capsules from a range of pathogenic bacteria are the key determinants of virulency. the capsule hasbeen implicated in virulence of pasteurella multocida. in this study a type-specific polymerase chain reaction(pcr) assay was used for capsular typing of 39 avian p. multocida isolates from iran. the pcr amplified afragment of 1044 bp from all of tested isolates. it was found that all avian p. mul...

The olefins polymerization process in a slurry reactor is discussed. The reaction rate dynamics was analyzed and the contributions of feed flow, gas-liquid mass transfer, polymerization reaction, and catalyst deactivation were estimated. The propylene solubility in a solvent mixture “heptane” was calculated using Soave-Redlich-Kwong equation of state. These data were then approximated by Henry-...

One-electron oxidation of anthraquinone (AQ)-linked DNA oligonucleotides containing A/T base pairs with repeating TT steps results in the distance-dependent reaction of the resulting radical cation and base damage at the TT steps that is revealed by subsequent reaction as strand cleavage. However, the inclusion of a remote guanine or GG step inhibits the reaction at thymine and results in predo...
