The regioselective ring opening of styrene oxide using elemental iodine and bromine in the presence of disulfides as new catalysts was studied. The conductivity titration and UV spectroscopy were used to study the interaction of iodine with these catalysts. The results indicate that disulfide 11 is efficient in polyiodide formation, and can catalyze this reaction in excellent yield and high reg...

The classical method of producing cellulose oligomers through hydrolysis microcrystalline (MCC) in phosphoric acid has been re-examined. Hydrolysis products are fractionated by precipitation to yield two types with different average degrees polymerization (DP). number- and weight-averaged molecular weights the lower DP fraction 1339 g/mol 1388 respectively, corresponding a polydispersity index ...

Kawasaki disease (KD) is an acute vasculitis of young children that can be complicated by coronary artery abnormalities. Recent findings suggest that a superantigen(s) may play an important role in stimulating the immune activation associated with the disease, although the origin of this superantigen(s) is unclear. Staphylococcus aureus, isolated from the rectum or pharynx of patients with KD, ...

ferdowsi's shahnameh is the document of our national and religious identity and analyzing its structural and conceptual dimensions and particularly studying it comparatively with other religious and mythological texts seems to be necessary in order to achieve greater understanding of its mysteries and to attain its moral and spiritual doctrines and messages in any era and for any generatio...

Abstract This discussion provides the first in-depth investigation into meaning and significance of a quite exceptional petition presented by parliamentary Commons in reign Richard II. The survives as unique copy chronicle Henry Knighton: it was not recorded on parliament roll. Knighton inserted his more general account Merciless Parliament 1388. In this I argue that is most likely to have been...
