    The Origin of Life on the Earth covers the proceedings of the First International Symposium of The Origin of Life on the Earth, held at Moscow on August 19-24, 1957. This symposium brings together numerous scientific studies on the evolutionary principles and the different stages in the evolutionary development of matter. This book is organized into seven parts encompassing 60 chapters. The first parts discuss evidence that on the formation of hydrocarbons and their derivatives on the surface of the Earth even before the emergence of life. The subsequent parts are devoted to the many asymmetrical syntheses under the influence of circularly-polarized ultraviolet light, by catalytic reactions occurring on the surface of quartz crystals, and spontaneously by slow crystallization from solutions. These topics are followed by reviews on the possible means of abiogenic formation of amino acids, porphyrins, protein-like polymers, polynucleotides and other high-molecular organic compounds. Considerable chapters explore the complete possibility of the primary formation of these compounds on the surface of the Earth even before life was present on it. Other general topics covered include nucleic acids, nucleoproteins and viruses. The last part considers general biochemical problems connected with the further development of metabolism. This book will be of value to astronomers, physicists, geologists, chemists, and biologists.

    • English
    Atomic Weights of the Elements 1975 outlines the different problems that arise from the imprecise definition of atomic weight or relative atomic mass. This book reviews the natural isotopic composition of the elements and tabulates the relative atomic masses for selected radioisotopes. This book is comprised of one chapter. This text begins with an overview of the problems arising from the actual or potential variability of the atomic weights of several elements. This book then discusses the significance of having informative labels on chemicals that are commercially available. The reader is also introduced to the concept of a defined standard atomic weight. This book discusses as well the important changes in annotations and the wordings of footnotes to the Table. This book is a valuable resource for chemists, teachers, and students. Research workers interested in atomic weights of the various elements will also find this book extremely useful.

    Register of International Rivers comprises international river and lake basins that form a substantial portion of the earth’s water resources, available for human use and consumption. This Register is prepared by the United Nations, Department of Economic and Social Affairs for sessions of the Economic and Social Council’s Committee on Natural Resources. This book is divided into seven sections that comprise separate river basins communicating directly with the final recipient of the water, including oceans, closed inland seas, and lakes. It includes all the world’s separate basins shared by two or more countries and in some cases most of the basin area is confined to one country and only a small part of it extends to one or more countries. All data are organized according to five major continental divisions: Africa, North and Central America, South America, Asia, and Europe. Two categories of tables are prepared for each major continental subdivision. One is a list of countries sharing river basins with other countries, while the other is a list of rivers and lakes forming international boundaries and showing the approximate length of the boundary waters.
