fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
The development of theoretical and mathematical physics has required various extensions of the four-dimensional Minkowski spaceM(1, 3) and, correspondingly, various extensions of the Poincaré group P (1, 3). The natural extension of this group is the generalized Poincaré group P (1, 4). The group P (1, 4) is the group of rotations and translations of the five-dimensional Minkowski space M(1, 4)...
