Taschenbuch. Zustand: Neu. Neuware - Dr W J Jenkins In 1977 when the Sheffield Transfusion Centre took delivery of the first GROUPAMATIC blood grouping machine in the UK it was equipped with a sample identification system involving complicated and expensive disposable punched cards. In fact, the cards were so expensive that Dr Wagstaff was unable to find the revenue to support the system. A year later, when Brentwood took delivery of a GROUPAMATIC, we were faced with the same problem, but by chance we heard that KONTRON was developing a laser scanning system for bar code labels and we were able to have our machine modified. Subsequently the Sheffield machine was altered to take the bar code scanner. At about the same time the Bristol Centre was helping TECHNICON with the development of the AUTO GROUPER C-16, and fortunately they decided on a laser reader of the same type for bar code identification. Thus there were three centres with the capability for reading bar codes on blood grouping machines and it became necessary to find someone to produce the bar code labels. There was only on~ printer in the UK who could produce labels to the required specification. To cut the costs of printing, and in the hope of avoiding a wide variation in codes, I invited representatives of centres interested in the problem to a meeting, where we set up what we called the Group of Six. This later became an official Working Party of the Regional Transfusion Directors.

Neuware - Friedrich Rapp, in this magisterial and critical essay on technology, the complex human phenomenon that demands philosophy of science, philosophy of culture, moral insight, and historical sensi tivity for its understanding, writes modestly of the grave and ten tative situation in the philosophy of technology. Despite the pro found thinkers who have devoted time and imagination and ratio nal penetration, despite the massive literature now available, the varied and comparative viewpoints of political, analytic, despite metaphysical, cultural, even esthetic commitments, indeed despite the honest joining of historical and systematic methods of inves tigation, we are far from a satisfactory understanding of the joys and sorrows, the achievements and disappointments, of the tech nological saga of human societies. Professor Rapp has prepared this report on the philosophical understanding of technology for a troubled world; if ever philosophy were needed, it is in the prac tical attempt to find alternatives among technologies, to foresee dangers and opportunities, to choose with a sense of the possibil ity of fulfilling humane values. Emerson spoke of the scholar not as a specialist apart, but as 'Man thinking' and Rapp's essay so speaks to all of us, industrial world or third world, engineers or humanists, tired or energetic, fearful or optimistic.

Buch. Zustand: Neu. Neuware - As editor of this volume I am not going to emphasize the economic im portance of the Bruchids of pulses, nor how necessary it is to know the conditions of infestation of crops in order to achieve an efficient protection; both points are testified by F.A.O.'s sponsorship, as well as of the International Organization for Biological Control. On the other hand I would like to stress the scientific interest of the study of 'domestic' bruchids. It raises questions which require that present basic entomological knowledge be extended. I am not going to review all questions raised but I will emphasize those I am most aware of. Some bruchid species have been able to colonize habitats differing totally; some differing in their latitude, and thus their basic periodicities; others differing in their degree of complexity (stocks of seeds): What are the respective roles played by polymorphism and plasticity in that exceptional capacity What differences are there between the populations living on wild plants in dispersal areas and those living in stocks What are the alterations brought about by the drastic selection pressures in populations having later colonized habitats ecologically similar to the original habitats What factors determine the degree of specificity of trophic relationships, and the possibilities of extension of the niche What influences are exerted by the other elements of the original bio cenoses upon the behavioural evolution of these species Such are a few fundamental problems that can be tackled directly through.

Buch. Zustand: Neu. Neuware - In recent years, it has become clear that the red-giant phase is one of the most dramatic periods in a star's life, when all of its parts become involved in ways that have both direct and indirect observational consequences. This is most particularly true of low- and intermediate mass stars during the second ascent of the giant branch. Such stars bring to their surfaces products of nucleosynthesis currently taking place in their deep interiors, they pulsate as Mira variables, develop extended outward-flowing atmospheres that may exhibit maser properties, and shed great quantities of matter, sometimes highly processed, into the inter stellar medium. The manner in which processed matter is brought to the surface is far from being completely explained, and the precise mechanism or mechanisms whereby matter is ejected from the stellar surface (whether by deposition of Alfven waves, radiation pressure on grains, or as a consequence of so me large scale envelope instability) has yet to be elucidated to every one's satisfaction. The purpose of the second workshop in Astrophysics, organized by the 'Advanced School of Astronomy', was to bring together experts on all the physical processes occurring in red giants in an effort to emphasize the interrelatedness of these individual processes, and to encourage a dia logue among experts that might serve to initiate a synthesis, or at least sharpen our understanding of the most important problems to address in the future.

Its aim was to bring together laboratory, fusion and space plasma physicists and to highlight the communality of basic plasma phenomena, similarities and differences observed in the laboratory and in space, thus exchanging information tnd views on new ideas to link both areas. Although similar type of conferences were held in Europe and recently in the States, this is the first time we have had in Japan for such an international meeting, which may be regarded as an extended version of our national Workshop held twice at the Institute of Plasma Physics of Japan (IPPJ) in 1976 and in 1977 (IPPJ Research Report No. 286 and No. 365). The Workshop consisted of seven regular sessions and one special session with approximately ninety participants from allover the world. Thirty-six papers, invited and contributed, were presented, nine from U. S. A., three from U. S. S. R., two of each from Germany, France, India, one of each from Sweden, Canada, Belgium and fifteen from Japan. The topics covered were: (1) The Critical Velocity (2) Beam Plasma Discharges and Interactions (3) Double Layers and Shocks (4) Instabilities in the Equatorial and Auroral Electrojets (5) Turbulent and Anomalous Plasmas (6) Plasma Irregularities (7) Solar Plasma Phenomena (8) Active Experiments in Space Plasmas and Their Simulation in the Laboratory.
