Among all the cell fragments obtaine,d experimentally which can make a great contribution to our knowledge of cell structure, an important place is occupied by contractile cell models.

In the last few years the physics of turbulent plasma has undergone rapid development, beginning with the first works, in which the term "turbulence" was used in various ways, and ending with the fundamental studies which provide a thorough examina­ tion of the turbulent state of plasma. In physics it is usually found that value is not so much contained in specific results for a partic­ ular field as it is in the more general outlook and overall view of the problem. Occasionally the older results take on new mean­ ing after the general view of things is perfected. In the case of the physics of turbulent plasma, this general picture is now com­ plete, for the most part. The first review devoted to the problem of plasma turbulence was written by B. B. Kadomtsev [in "Problems in Plasma Theory," edited by M. A. Leontovich, Volume 4, Moscow, Atomizdat (1964), p. 188; English Translation: "Plasma Turbulence," Academic Press, London (1965)].

The main theme of this monograph - conditions of regenera tion of organs in mammals - reflects an area of increasing empha sis which permeates much current Soviet research on regeneration.

In particular, any ambiguities as to the identity of organisms described only by common names in the original text were removed, because the author kindly supplied the Latin names in all such cases. A final chapter, "Recent Work on the Evolutionary Ecology of Ani mals," is presented as Appendix II to the translation of the original text.

Moscow September 1972 v Preface Gas -chromatographic analysis for impurities is presently a rapidly developing area in gas chromatography, because many practical topics give considerable importance to impurity analy sis.

Nearly three years have passed since the publication of the original Russian edition, in which time there have appeared various papers on recent research on the transuranium elements, of which the most notable concern the production of element 105 at Dubna and Berkeley.

(Written for the original Russian edition) Out of all the functional groups of protein molecules that be long to the side chains of amino acid residues, the sulfhydryl or thiol (SH) groups of cysteine residues and the disulfide (S-S) groups of cystine have for long attracted particular attention from chemists and biochemists.

I am very glad to write a few introductory words to this important book by Professor Deryagin and his colleagues Drs.

I have had the privilege of conversing with Professor palladin on numerous occasions during the last 15 years of his life. The present book reflects, in addition to his warmth and wit and wisdom, Dr. Palladin's approach and style: how he and his collaborators came to their conclusions after careful consid eration of all the facts.

This book presents a brief review of the main re sults obtained in two new branches of plasma physics that have developed rapidly in the last decade following the launching of artificial satellites.

Sintering of powder metal compacts is one of the basic oper ations in powder metallurgy. Analysis of the laws of sintering may provide addition al material for more complete phenomenological characteristics of these processes that will be useful for further development of theoretical concepts of the flow of imperfect crystals under small loads.

This monograph gives an up-to-date account of the original results of the author's research in the complex field of the central control over relationships which have become established in the course of evolution between the hypothalamus and the pituitary gland.

The book we are presenting to American and other English speaking readers is a review of the work on the electron struc ture of elements, alloys, and compounds, which was started back in the fifties.

This collection conta ins the results of a number of investiga tions which have been carried out in the Hydrothermal Synthesis Laboratory of the Institute of Crystallography, Academy of Sciences of the USSR;
