As environmental legislation concerning leaks and emissions tightens this practical reference manual is a must for all those involved with systems using leak-free (or seal-less) pumps or compressors. This handbook will enable you to understand the various designs and properties of leak-free pumps and select the right pump or compressor to ensure leak free systems whatever the application.

It was with great pleasure that I accepted Professor Wackenheim's invitation to write the preface of this most interesting monograph. During the international course on neuroradiology in Obernai, organized by Professor Wackenheim in 1978, an entire day was devoted to discussions about various aspects of stenosis of the lumbar vertebral canal. As Professor Wackenheim and his group, in particular Dr. E. Babin, had thorough. ly studied this field, it was an excellent occasion for the exchange of views through personal contact. Their support of basic views such as attributing the cause of stenosis to a developmental disturbance of growth of the neural element - the vertebral arc- and spontaneous agreement about essentials in classification and nomenclature facili tated this exchange. Reading the present monograph made me think back to 1949 when I wrote my first publication on stenosis of the lumbar vertebral canal in a French volume that com memorated my teacher in neurosurgery, Professor Clovis Vincent. During the following years it was impossible to publish a more detailed paper on the subject in international journals since their editorial boards did not believe in its occurrence. My first English papers were published in the Journal of Bone and Joint Surgery (1954, 1955), but it was only during the 1970s that this form of stenosis became more universally recog nized."

Clear evidence of increasing demands in the processing industry prompted the editors and authors to publish a new book about "High Pressure Process Technology: Fundamentals and Applications."
This book presents the latest knowledge regarding the high pressure processing aspects combined with that about the modeling, the design and the operation of safe and reliable high pressure plants and equipment. This treatment and selection of the subjects is stimulating and unique. Consisting of nine chapters, each subdivided into several sections, the book addresses the high pressure aspects, providing well selected correlated information connected with a comprehensive overview together with a large number of references.
The main body of the first eight chapters refers to subjects like high pressure in general, the thermodynamics and kinetics of the fluids involved, the design of high pressure equipment, the modeling and design of reactors, separation and fractionation units, the safety aspects, the control and economics.
In the extended last chapter, examples of promising high pressure applications are explained, such as chemical and enzymatic reactions in supercritical solvents, hydrogenation under supercritical conditions, supercritical water oxidation, polymerization with metallocene catalysts, supercritical extraction, fractionation and precipitation, supercritical pharma processing, ultra-high pressure sterilization and supercritical dry-cleaning.

Allgemeinmediziner, Rheumatologen, Orthopaden, Internisten, Neurologen, Krankengymnasten und Masseure sehen sich nahezu taglich mit den verschiedensten Auspragungen weichteilrheumatischer Erkrankungen und anderen Schmerzsyndromen des Bewegungsapparates konfrontiert. Bei Sheon finden sie eine systematische Darstellung der diagnostischen und therapeutischen Problemloesungen. Die Autoren stellen das jeweils Typische und Wesentliche einer bestimmten Krankheitsform heraus und schliessen daran individuelle Diagnosen und gezielte Therapieempfehlungen an. Das Buch zeugt von einem nuchternen Pragmatismus, der sowohl pathophysiologischen wie pathopsychologischen Faktoren Rechnung tragt.

Zu den sogenannten physikalischen Arbeitsschaden, die in der erweiterten Berufskrankheitenliste durch die 5. Berufskrankheitenverordnung eine be sondere Beachtung erfahren haben, gehoren die Erkrankungen der Sehnen scheiden sowie der Sehnen-und Muskelansatze. Das vorliegende 2. Beiheft zum "Zentralblatt fur Arbeitsmedizin und Arbeits schutz" der Deutschen Gesellschaft fur Arbeitsschutz soll einen Diskussions beitrag zur Klarung von Unsicherheiten bei der Begutachtung solcher chro nischer, durch uberbeanspruchung entstandener Erkrankungen leisten.
