Origin and Aims of this essay It was not by choice but by the misfortunes or fortunes of the last war, that I became involved with rivers. In December 1946 I obtained a lecturing post at the then Gordon Memorial College at Khartoum and the Principal of the college brought me to confluence of the two Niles and urged me to 'do something' on the biology of the river. I was very reluctant, my experience was limited to lakes in Poland up to 1939, a...

Scope and limitations of this book I am trying here to present the natural history of a land largely created and dominated by two great rivers, the Euphrates and Tigris. All rivers have two main functions, quite different from lakes, they transport water and eroded material sometimes over large distances. The astute Greeks, who penetrated here in the 4th century B.C., called the land Mesopotamia, an apt name, it is the only region in the Near ...

This book is unique in supplying a comprehensive presentation of high pressures, negative pressures, random constraints and strong electric field exogenic (external) impacts on various soft matter systems. The book is an excellent guide in this novel and still puzzling research area. The book comes as a result from the ARW NATO brainstorming discussion in Odessa, Ukraine (8-12 Oct. 2005). It contains 31 papers prepared by key specialists in th...

Complex liquids constitute a basic element in modern materials science, their significant features include self-assembly, mesoscale structures, complex dynamics, unusual phases and enormous sensitivity to perturbations. Understanding their nature and properties are a great challenge to modern materials science that demands novel approaches. This book focuses on nonlinear dielectric phenomena, particularly on nonlinear dielectric spectroscopy (...
