    Notes: [Auszug] During 1968, the Polish-Mongolian palaeontological expeditions collected in the locality of Bayn Dzak7 (Shabarakh Usu) in the Gobi Desert of the Mongolian People's Republic. There I found in situ in the sandstone of the Djadokhta Formation, which is presumably of the Coniacian-Santonian age8, a ...

    Notes: [Auszug] Paramagnetic centres representing both free radicals and transition metals, as well as their complexes, have been detected in metabolic systems1. The former are characterized by a narrow, slightly asymmetric singlet with a half-width of 7-8 G for a lyophilized sample and 14-15 G for wet and frozen ...

    Notes: [Auszug] BALLS of fire, or ball lightning, which this book is about, have not been tamed; they are shrewish, ill-disposed and mischievous as ever. If anybody does not believe in them, let him read this book. It is best to read straight through, for the dispersion of numbered "case histories" in the text ...

This book is an attempt to provide seismologists with sufficient mathematics ...

    Notes: [Auszug] THIS book obviously had to be compared with the one of identical title by Garbuny (Academic Press, 1965). In the earlier book, optical physics is defined as "the study of dynamic interactions between light and matter and the conclusions on structure and state that can be derived from optical ...

    Notes: [Auszug] THE field studies of non-human primates carried out in the early 1960s are catching the imagination of an increasing number of social scientists; these studies show that the social life of men is similar to that of apes and monkeys in a number of ways, suggesting the operation of innate mechanisms ...

    Notes: [Auszug] As Dr Sweeney has stated in her preface, this is a book about one half of a subject, and it therefore starts off at a tremendous disadvantage. The wisdom of confining such a book to plants, and of omitting almost all the important recent work on animal systems, is no doubt clear in the minds of the ...

    Notes: [Auszug] WITH the death of Captain Cyril Roper Pollock Diver, on February 17, we have lost a great natural historian. Although his interest in biology started at an early age he had no formal training in the subject. The most productive period of his life began in 1918 when he was invalided out of the Army. ...

    Notes: [Auszug] THE first successful collisions of electrons and positrons in the Italian storage ring ADONE were reported in Nuovo Cimento Letters on May 21 by Professor Fernando Amman and his colleagues. Wideroe first had the idea of making beams of particles collide in 1947; nobody seems to have noticed his ...

    Notes: [Auszug] A SUGGESTION that may ultimately reduce the cost and improve the performance of high-energy particle accelerators has recently been made by N. C. Christo-filos in Physical Review Letters (22, 830; 1969). Christo-filos's proposal is essentially a modification of the collective-ion acceleration ...
