The present book primarily deals with the lower rim substituted calix[4]arene derivatives and their metal ion complexes, and the biomimetic and biological studies of these complexes. Broadly, the book could be divided into the following three parts: (i) The K+ was found to act as template in the formation of calix[4]arene tetra-amide derivative exclusively, with the generation of calix[4]arene-monoanion and the structure of this has been characterized by single crystal XRD study. (ii) Metal ion complexes of p-tert-butylcalix[4]arene-diacid with Mn(II), Mn(IV), Fe(III), Co(II),...

The purpose of this book is to supply the basic Geologic and Geophysical informations about the Miano Area, Sindh Pakistan. Using seismic Reflection Method to explore the subsurface structures and the natural Resources (Hydrocarbons) and to understand what lies beneath the surface of Earth using the data resulted from surveys conducted by OMV, Pakistan. The studied area is a good reservoir area. This book contains the introduction to the Area, its General Geology, Geomorphology and Tectonic frame work. From exploration point of view this area is very important. Major structures observed in...
