Synthetic porphyrins have, in the last years, gained increasing interest in analytical chemistry as unique reagents for the detection of metal ions. The porphyr
In the present work a possibility of computation modeling, which should be realized in a real quantum computer, is discussed. In this connection two models of a
The thermal conductivity, thermal diffusivity and heat capacity per unit volume of dunite rocks taken from Chillas near Gilgit, Pakistan have been measured simu
The distribution of metals (Cd, Cr, Pb, Cu, Ni and Zn) was determined in sediment cores collected from five major areas representing different anthropogenic act
