ansa - Metallocene derivatives XXIII * .

9 Titanocene and zirconocene complexes with a phenyl or I-naphthyl substituent in one ,B-position of each Cs-ring ligand and with an interannular tetramethylethanoor dimethylsilano-bridge have been prepared. Racemic complex isomers, which are formed together with varying amounts of their meso isomers, were separated from the latter and characterised by lH NMR spectroscopy and X-ray crystallogra...

the Baku - Tbilisi - Ceyhan ( BTC ) pipeline Cyber

Initial reports surfaced in 2009 that a state-sponsored cyber actor had successfully intruded upon servers essential to the BTC pipeline operations and caused a temporary disruption in pipeline transfers. It was further reported that a team of western experts were able to assist the pipeline operator in restoring the system enabling a return to normal operations. Few details were provided other...

Mathematical Modeling Pollution From Heavy Traffic in Tbilisi Streets

Using mathematical simulation, distribution of concentration of harmful substances NOx at Rustavely Avenue, the crossroad of David Agmashenebeli and King Tamar Avenue, where traffic is congested, and for the whole territory adjoined to the crossroad have been studied. In addition, there have been investigated influences of traffic-lights at streets' intersections on the growth of concentration ...
