Titre : Advances in oceanography Type de document : texte imprimé Auteurs : Charnock, Henry, Auteur Editeur : Plenum press Année de publication : 1978 Importance : 356 p. Format : 26 cm ISBN/ISSN/EAN : 978-0-306-40019-3 Langues : Anglais (eng) Index. décimale : 551 Géologie, météorologie, hydrologie générale Résumé : The papers at the general symposia of the joint oceanographic assembly were presented by authors who had been invited to deal with topics of broad interdisciplinary interest.Together they gave a valuable account of the present state of marine research, its problems and potential.
There seems merit in publishing them in one volume and we are grateful to the authors who kindly agreed to prepare their papers for publication. This has taken some time (and not all authors found it possible) but we hope the resulting volume is still indicative of trends in modern oceanography. Particularly noticeable is the way in which the applied aspects are beginning to play a more important part in spite of worries about the effects of the law of the sea on our freedom to make observations.
We are especially grateful to the four authors who agreed to give lectures summarising the work in their own field which was reported at the assembly. We also wish to thank the other authors, as well as all concerned with the assembly and with the production of this volume.Advances in oceanography [texte imprimé] / Charnock, Henry, Auteur . - Plenum press, 1978 . - 356 p. ; 26 cm.

Titre : Marine science instrumentation : proceedings of the symposium on transducers for oceanic research (volume 2) Type de document : texte imprimé Auteurs : Gaul, R. D., Auteur Editeur : Plenum press Année de publication : 1963 Importance : 195 p. Format : 28 cm. Langues : Anglais (eng) Index. décimale : 551 Géologie, météorologie, hydrologie générale Résumé : The scope of the "Symposium on Transducers for Oceanic Research" was expressly limited to measurement devices because it seemed that transducers present the greatest technological obstacles to the advance of research in and over the ocean. It is appropriate that the second major meeting staged by the Marine Sciences Division of the Instrument Society of America should focus on the basic sensing devices in spite of the fact that national attention in oceanography, undersea warfare and marine engineering seems to be concerned with large systems and elaborate schemes. Ocean science and technology, under the pressure of practical demands for knowledge, is placing considerable stress on mental and physical resources at hand. In the final analysis scientific goals and operational concepts must recognize the limitations of tools and technology available for measurement if their planning is not to lead to frustration and failure.
Oceanography, like all other experimental sciences, requires the services of scientists and engineers from fields far removed from its basic areas of inquiry. Until fairly recently this requirement has been met by a small number of extremely versatile men who managed to design, and frequently hand-build, the apparatus they needed for their investigations. Most of the successful instruments in use today derive from this source. Present needs for instrumentation exceed the capacity of those rarely talented individuals who can bridge the gap between science and engineering with proficiency.
As the ocean research effort gains momentum organizations and professional people are moving with their talents and experience from related fields in an attempt to fill the stated needs. These same demands are pressing specialization and consequently widening the gap between people who design instruments and those who use them. Success must necessarily depend on the degree of mixing achieved. The science will not be served by conversations held exclusively among instrumentation engineers, nor are better instruments likely to appear unless scientists are continuously aware of advances in technology. Statements of needs and appreciation for the limits within which they may be satisfied are necessary before the applied scientist and engineer can offer the new measurement techniques that may make feasible previously impossible experiments. We believe that the collection of papers in this volume shows a high degree of mixing and offers a significant contribution to the fund of knowledge so essential to the advance of marine science.
During the course of the Symposium from which this volume has been drawn, one of the most successful practitioners of the art of oceanographic instrumentation remarked that he was disappointed in the number of papers describing instruments that had not yet emerged from the laboratory. His criterion for a successful paper required actual scientific data gathered with the" instrument in question and a report based only on the results of prolonged field use. No one can argue the merit of a thorough testing in the environment as a means for evaluating an instrument; neither can an instrument be considered useful until it has contributed to a successful investigation. However, the rapid expansion of effort in the marine sciences demands an early transfer of information on research and development in progress if duplication and overextension are not to cause ineffectiveness through dilution of our resources.Marine science instrumentation : proceedings of the symposium on transducers for oceanic research (volume 2) [texte imprimé] / Gaul, R.

Titre : Mass spectrometry Type de document : texte imprimé Auteurs : Jayaram, R., Auteur Editeur : Plenum press Année de publication : 1966 Importance : 225 p. Format : 25 cm Langues : Anglais (eng) Index. décimale : 530 Physique Résumé : This book on mass spectrometry is the practical result of an intense desire on the author's part to obtain a concise and panoramic view of the recent theoretical and experimental developments in this field.
In reality, the most of books written have been directed to the chemist, rather than the physicist or space-physicist, in spite of the fact that the mass-spectrometric techniques have recently been applied extensively in space research, and most of the techniques of mass measurement are outgrowths of contribution made by the physicists.
This book is intended to provide an introduction to the various theoretical and experimental techniques in mass spectrometry, with special treatment of the applications of mass spectrometers to the study of ionospheric composition and problems.
The book should, in fact, be of interest to both theoretically and experimentally oriented readers, but a good background in differential and integral calculus presenter in the book. Graduate students( in physics, chemistry, or engineering) preparing for a course in mass spectrometry may find this book useful as a text or a reference book, and for chemists, it provides a comprehensive survey of various techniques currently available for mass separation.
The first chapter provides an introduction to mass spectrometry and spectrographs, particularly the classic magnetic types; the second chapter deals with the theoretical and the experimental techniques of the mass measurement using magnetic mass spectrometers; the third chapter provides a discussion of time-of-flight mass spectrometers. The fourth chapter deals with RF mass spectrometers; the fifth chapter discusses cyclotron resonance instruments as mass analyzers; the sixth chapter deals with the role of mass filters as mass spectrometers; and the last chapter is devoted to the study of applications of nonmagnetic mass spectrometers to upper atmospheric research.Mass spectrometry [texte imprimé] / Jayaram, R., Auteur . - Plenum press, 1966 . - 225 p. ; 25 cm.

Titre : New developments in marine biotechnology Type de document : texte imprimé Auteurs : Le gal, Y., Auteur Editeur : Plenum press Année de publication : 2010 Importance : 343 p. Format : 26 cm ISBN/ISSN/EAN : 978-1-4419-3300-3 Langues : Anglais (eng) Index. décimale : 660 Technologie chimique (chimie industrielle) et techniques connexes Résumé : Past efforts to colonize the environment and domesticate living species, coupled with scientific research, have resulted in the possession (but not always the real control) by humans of any available terrestrial space. However, oceans, which represent up to two-thirds of the surface of the planet, had not been really approached until the middle of this century. As oceanographic science develops, the picture of a rich, diverse, complex and also, in many respects, specific marine life, is coming into view.
In a broad sense, marine biotechnologies can be understood as the various means or techniques of managing marine living systems for the benefit of mankind. The first goal we have is for marine life to provide biomass for food. However, today it is not certain that a significant increase of total world fisheries' catches will be possible in the future. There are several ways to address this. First, we need to generate better, more complete, or different uses of the biomass actually fished. This is mainly a matter of upgrading fish and fish wastes. Second, we need to artificially grow the Jiving species. This falls within the scope of cell cultivation and of aquaculture. Both approaches have to be appreciated simultaneously in terms of biology, ecology, and economy. In both approaches, profit improvements are linked to the introduction of biotechnological methods and to the use of biotechnological processes.
The main characteristics of fished biomasses is that they still exist and are readily available. They can be considered a huge reservoir of molecules: polysaccharides, enzymes, fats, etc., exhibiting physical, chemical, or biological activities of interest for various purposes. The main problem (and it is not a minor one), in terms of techniques and cost, is to isolate and purify these molecules. The second issue in biomass treatment is mass cultivation of marine organisms. It is now clear that trying to reproduce biomass intensively and artificially cannot easily yield profits, unless we use a series of biotechnological tricks that will permit a drastic lowering of the costs. During the last 10 years, another important problem has emerged. This is the spreading of pathogenic organisms in overcrowded sea farms. Within a short period of time, sea farms could be almost com pletly destroyed by marine viruses, microorganisms, or parasites about which we have little information.
Solutions to these problems represent real strategic tasks for the marine biotechnolo-gists requiring basic research in developmental biology, genetics, gene enginering, endocrinology, pathology, and immunology of species as different as flatfish, salmon, shrimps, abalone, among others.New developments in marine biotechnology [texte imprimé] / Le gal, Y., Auteur . - Plenum press, 2010 . - 343 p. ; 26 cm.
