Product Description: The theory of the stability of motion has gained increasing signifi­ cance in the last decades as is apparent from the large number of publi­ cations on the subject. A considerable part of this work is concerned with practical problems, especially problems from the area of controls and servo-mechanisms, and concrete problems from engineering were the ones which first gave the decisin' impetus for the expansion and modern development of stability theory...read more

Product Description: After several decades spent in astronomical semi-obscurity, the Moon has of late suddenly emerged as an object of considerable interest to students of astronomy as well as of other branches of natural science and technology; and the reasons for this are indeed of historical significance...read more

Product Description: Upon the publication of her posthumous volume of poetry, Ariel, in the mid-1960s, Sylvia Plath became a household name. Readers may be surprised to learn that the draft of Ariel left behind by Sylvia Plath when she died in 1963 is different from the volume of poetry eventually published to worldwide acclaim...read more

K. O. KIEPENHEUER ( Fraunhofer Institut, Freiburg i. Br., Germany) The present symposium, to my knowledge the largest ever held in the field of solar research (170 astronomers from 21 countries) was held in the building of the Hun­ garian Academy of Sciences in Budapest from September 4 to 8, 1967. It was the 35th symposium organized and sponsored by the International Astronomical Union. The majority of participants were financedfrom national sources. The Organizing Commit­ tee consisted of K. O. Kiepenheuer (Chairman), L. Davis, L. Dezso (Local Organizer), A.D. Fokker, R. Michard, A.B. Severny, H.J. Smith, Z. Svestka, and H. Tanaka. In order to ensure prompt publication, the manuscripts had to be supplied by the authors 1 month after the meeting. The discussions have been recorded on tape. Their reproduction in this book, however, is based almost completely on the contributors' writing down their comments and questions on the spot. Two special projects have been reported and discussed shortly during the sym­ posium: The world wide project 'Cooperative Study of Solar Active Regions' (CSSAR) organized by Dr. R. Michard, under the auspices of the IAU, which has put at the disposal of our solar community a precious observing material on Active Regions over a period of 6 months.

Many real and potential hazards will face astronauts* during operations in space. Some of these hazards might be of little medical significance; others might produce serious medical problems. This book is an initial attempt to describe the characteristics and suggest the management of possible medical problems which might arise from hazards of space operations. Attention is not given here to the so-called 'naturally occurring' diseases. Writing is oriented to future interplanetary missions during which, due primarily to the time required to return to earth, the diagnosis and definitive or interim treatment of medical problems will have to be carried out in space. It is therefore assumed that suitable diagnostic and treatment facilities and medically trained personnel will be available on advanced spacecraft, in which large, multidisciplined crews will be living in a comfortable, 'shirt-sleeves' environment. To lay the groundwork of Space Clinical Medicine, a field in which very little has been written and essentially no experience gained to date, it was found necessary to consider clinical manifestations, diagnosis, and treatment of possible medical problems in space. Wherever necessary, various hazards of space operations are defined and analysed in order to determine their possible medical effects. The patho­ physiologic characteristics of medical problems are discussed, frequently in detail, to provide the rationale for their prevention and treatment.
