by Paul A. Libby

In this and a following issue (Vol. VIII, 1962, Fasc. 2-3) of "Astronautica Acta" there will appear the papers presented at the first international symposium sponsored by the International Academy of Astronautics of the International Astronautical Federation. The theme of the meeting was "Space Flight and Re-Entry Trajectories." It was held at Louveciennes outside of Paris on June 19-21, 1961. Sixteen papers by authors from nine countries were presented; attendees numbered from 80 to 100. The organizing committee for the symposium was as follows: Prof. PAUL A. LIBBY, Polytechnic Institute of Brooklyn, U.S.A., Chairman; Prof. LuiGI BROGLIO, University of Rome, Italy; Prof. B. FRAEIJS DE VEUBEKE, University of Liege, Belgium; Dr. D. G. KING-HELE, Royal Aircraft Establishment, Farnborough, Rants, United Kingdom; Prof. J. M. J. KooY, Royal Military School, Breda, Netherlands; Prof. JEAN KovALEVSKY, Bureau des Longitudes, Paris, France; Prof. RuDOLF PESEK, Academy of Sciences, Prague, Czechoslovakia. The detailed arrangements for the meeting were made in a most satisfactory manner by Dr. FRANK J. MALINA, Deputy Director of IAA and Mr. A. R. WEILLER, Acting Secretary of IAA. Prof. THEODORE VON KARMAN, Director of IAA, in his remarks closing the symposium indicated his satisfaction at the interest being shown in "the science of the future." The papers which follow will make a permanent contribution to the literature of this science.

La geometrie des groupes classiques: Reihe: Gruppentheorie (Ergebnisse der Mathematik und ihrer Grenzgebiete. 2. Folge #5)

by Jean Dieudonne

This book gives an excellent survey of recent work on classical groups, simplifying and unifying the results of many authors. No attempt is made to cover all of the voluminous literature on classical groups; the author deals with only that portion of the subject which can be handled by the methods of linear algebra. By thus restricting his scope, he is able to include proofs of most of the results described, thereby making the book more self-contained than most Ergebnisse tracts.In the reviewer's opinion, this is an important and well-written book which should help to stimulate research on the classical groups. The book not only gives a thorough exposition of the present state of the subject, but is also an excellent introduction to the modern techniques basic to further work in this field.

Residue Reviews / Rückstands-Berichte: Residues of Pesticides and Other Foreign Chemicals in Foods and Feeds / Rückstände von Pesticiden und Anderen Fremdstoffen in Nahrungs- und Futtermitteln (Reviews of Environmental Contamination and Toxicology #2)

by Francis A. Gunther

Residues of pesticides and other "foreign" chemicals in foodstuffs are of concern to everyone everywhere; they are essential to food production and manufacture, yet without surveillance and intelligent control some of those that persist could at times conceivably endanger the public health. The object of "Residue Reviews" is to provide concise, critical reviews of timely advances, philosophy, and significant areas of accomplished or needed endeavor in the total field of residues of these chemicals in foods, in feeds, and in transformed food products. These reviews are either general or specific, but properly they may lie in the domains of analytical chemistry and its methodology, biochemistry, human and animal medicine, legislation, pharmacology, physiology, regulation, and toxicology; certain affairs in the realm of food technology that are concerned specifically with pesticide and other food-additive problems are also appropriate subject matter. The justification for the preparation of any review for this book­ series is that it deals with some aspect of the many real problems arising from the presence of residues of foreign chemicals in foodstuffs. The scope of "Residue Reviews" is international. It encompasses those matters, in any country, which are involved in allowing pesticide and other plant-protecting chemicals to be used safely in producing, storing, and shipping crops. Added plant or animal pest-control chemicals or their metabolites that may persist into meat and other edible animal products (milk and milk products, eggs, etc.

Entzündung I / Inflammation I: Unspezifische Entzündungen / Non-specific Inflammations / Inflammations Non-Spécifiques (Handbuch der Urologie Encyclopedia of Urology Encyclopedie d'Urologie #9 / 1)

Von E. WILDBOLZ In den letzten Jahren ist die Pyelonephritis, vor allem die chronische Pyelo­ nephritis, immer mehr in den Brennpunkt des medizinischen Interesses gerückt. Klinische und anatomische Arbeiten zeigen ihr außerordentlich häufiges Vor­ kommen. Sie ist heute die bedeutendste Gruppe der Nierenerkrankungen, ja sie hat sogar die Infektionen der Atemorgane von ihrem ersten Rang in der Häufigkeitsskala aller Infektionskrankheiten bei Spitalpatienten verdrängt. Auch der langsam Reagierende muß sich Rechenschaft davon ablegen, daß hinter der harmlosen Etikette einer chronischen Pyurie, einer chronischen Cystitis, einer Cystopyelitis, einer "empfindlichen Blase" sich oft eine Erkrankung verbirgt, die sich über Jahrzehnte hinzieht, progredient ist und schließlich, aller Therapie trotzend, zum Tode führt. Die pyelonephritische Schrumpfniere übertrifft an Zahl bei weitem alle anderen Schrumpfnieren. Diese Untersuchungen haben ferner ergeben, daß die atypischen Formen der chronischen Pyelonephritis ebenso häufig wie die typischen Formen sind, bei denen die chronische Pyurie auf den Ursprung der Erkrankung hinweist. Wir müssen also nicht nur diese Pyurien richtig deuten und auslegen, sondern wir müssen auch bei Erkrankungen wie Anämie, Adynamie, Neurose, an den renalen Ursprung der Allgemeinstörungen denken. Durch alle Studien, die sich etwas ausführlicher und eingehender mit der Klinik der chronischen Pyelonephritis befassen, zieht sich wie ein roter Faden die Verzweiflung über die Ohnmacht unserer Therapie. Die Therapie mit Anti­ biotica, die in akuten Fällen so viel Gutes zeitigt und die bei ihrer Einführung die Ausmerzung aller Infektionskrankheiten erwarten ließ, versagt.

Stress Waves in Anelastic Solids: Symposium Held at Brown University, Providence, R. I., April 3–5, 1963 (IUTAM Symposia)

by Herbert Kolsky William Prager

Although the subject of wave propagation in solids has a long history, the classical theory of elastic waves having been developed in the nine­ teenth century by STOKES, POISSON, RAYLEIGH and KELVIN, the last two decades have seen a remarkable revival of interest in this subject among both theoreticians and experimenters. There' are a number of reasons for this; first, experimental methods for the generation and detection of high frequency mechanical waves have become available only with the advent of electronic techniques and of high speed photo­ graphic recording apparatus. Secondly, the appearan

Düngung der Kulturpflanzen: Erste Hälfte (Handbuch der Pflanzenernährung und Düngung #3 / 1)

Seit dem Erscheinen des zweibändigen Standardwerkes von F. HONCAMP, "Handbuch der Pflanzenernährung und Düngerlehre", sind mehr als dreißig Jahre vergangen. Bei den stürmischen Fortschritten auf allen Gebieten der Natur­ wissenschaften, insbesondere der Chemie, Pflanzenphysiologie, Biochemie, Bodenkunde und Technologie, ist dieses zur Zeit seines Erscheinens so aus­ gezeichnete Handbuch natürlich längst veraltet. Zweifellos besteht heute ein dringendes Bedürfnis nach einem ähnlichen Werk. Wenn wir von dem ursprünglichen Plan abgekommen sind, das HONCAMP­ sche Handbuch in neuer Auflage zu bearbeiten, so vor allem deswegen, weil die tiefgreifende Entwicklung auf diesem Gebiet eine völlig neue Gestaltung des Werkes geboten erscheinen ließ. Es gliedert sich nun in drei Bände. Band I behandelt im wesentlichen die physiologischen Grundlagen der Pflanzenernährung. Er enthält eine ausführliche und systematische Darstellung der eigentlichen Ernährungsphysiologie. Auf eine Erörterung der allgemeinen pflanzen­ physiologischen Grundlagen konnte dabei verzichtet werden, weil im RUHLAND­ sehen "Handbuch der Pflanzenphysiologie" ein umfassendes und modernes Nach­ schlagewerk zur Verfügung steht. Band II beschäftigt sich mit dem Boden und den Düngemitteln. Unter Berücksichtigung der modernen Agrikulturchemie haben wir das heutige Wissen über den Boden als Standort und Nährstoffquelle der Pflanze unter den Verhält­ nissen der landwirtschaftlichen Praxis und des Gartenbaues bzw. des Forstwesens systematisch zusammengefaßt. Die folgenden Kapitel befassen sich mit der Beschreibung und Herstellung der verschiedenen Wirtschafts- und Handels­ düngemittel. Gerade auf diesem Gebiet bestehen in der wissenschaftlichen Literatur erhebliche Lücken, da keine größeren Lehr-oder Handbücher vorhanden sind, die sich eingehender mit der Technologie der Düngemittel und der Düngung beschäftigen.

Proceedings of the First International Symposium on Basic Environmental Problems of Man in Space: Paris, 29 October — 2 November 1962

by Hilding Bjurstedt

This volume contains the communications and discussions of the First Inter­ national Symposium on Basic Environmental Problems of Man in Space, which was held 29 October - 2 November 1962 at Unesco House, Paris, under the joint sponsorship of the International Astronautical Federation (IAF) and the International Academy of Astronautics (IAA) with the cooperation and support of Unesco, the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO). At this Symposium 31 communications were presented, 8 of which were from the USSR, 8 from the USA, and 15 from other countries, all by special invitation. The presentations, which included three general review papers, were made in ten half-day working sessions by a distinguished international group. The pro­ ceedings were not restricted to the acute professional aspects of man in space. In fact, the majority of the vast store of material contained in this volume deals with the more scientific aspects, i. e. with problems of the future, which are con­ tributed mainly by conventional areas of physiology and psychophysiology, including the technical research activities pertaining to the acquisition, analysis and control of biomedical data.

Residue Reviews / Rückstands-Berichte: Residues of Pesticides and other Foreign Chemicals in Foods and Feeds / Rückstände von Pesticiden und Anderen Fremdstoffen in Nahrungs- und Futtermitteln (Residue Reviews/rückstandsberichte Ser. #8)

by Francis A. Gunther

That residues of pesticide and other "foreign" chemicals in foodstuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the individuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food­ additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being displaced by newly developed ones more acceptable to food technologists, pharma­ cologists, toxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are also of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals persisting into our food­ stuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.
