Available in PDF, EPUB and Kindle. Book excerpt: LE SYSTEME FAISCEAU-PLASMA PEUT-ETRE CONSIDERE COMME UN PARADIGME DE LA TURBULENCE PLASMA. DANS CE SYSTEME, LE FAISCEAU CONSTITUE UNE SOURCE D'ENERGIE LIBRE POUR L'EXCITATION DES ONDES TURBULENTES: CES ONDES MODIFIENT LE MOUVEMENT DES PARTICULES DU FAISCEAU QUI ELLES-MEMES AFFECTENT L'EVOLUTION DES ONDES. L'EFFET AUTOCOHERENT DE L'INTERACTION ONDES-PARTICULES EST UN PROBLEME OUVERT. NOTAMMENT L'INFLUENCE DES COUPLAGES DE MODES INDUITS PAR LES PARTICULES RESONNANTES RESTE UN SUJET CONTROVERSE. DANS UN TEL SYSTEME, LE PLASMA JOUE ESSENTIELLEMENT LE ROLE D'UN DIELECTRIQUE SUPPORTANT DES ONDES ELECTROMAGNETIQUES ET PEUT ETRE AVANTAGEUSEMENT REMPLACE PAR LA STRUCTURE A ONDE LENTE D'UN TOP. NOUS MONTRONS DANS LA PREMIERE PARTIE L'ANALOGIE QUI EXISTE ENTRE LES DEUX SYSTEMES FAISCEAU-PLASMA ET TOP. EN DEUXIEME PARTIE, NOUS PRESENTONS LES RESULTATS DE SIMULATIONS NUMERIQUES DECRIVANT, A L'AIDE D'UN HAMILTONIEN AUTOCOHERENT, L'INTERACTION DE N PARTICULES AVEC UNE SEULE ONDE. POUR DIFFERENTES CONDITIONS INITIALES, NOUS OBSERVONS LA CROISSANCE EXPONENTIELLE DE L'ONDE DE FAIBLE AMPLITUDE PREVUE PAR LA THEORIE LINEAIRE. ALORS QUE POUR N PARTICULES REGROUPEES EN UN FAISCEAU MONOCINETIQUE, NOUS OBSERVONS BIEN LE REGIME DE SATURATION NON LINEAIRE ASSOCIE AU PIEGEAGE DU FAISCEAU PREVU THEORIQUEMENT, LORSQUE LE FAISCEAU PRESENTE UNE GRANDE DISPERSION EN VITESSE, LE SYSTEME DEVELOPPE, APRES LA PREMIERE SATURATION, UNE INSTABILITE DONT L'ORIGINE DEMEURE INEXPLIQUEE. EN TROISIEME PARTIE, NOUS DECRIVONS PRECISEMENT LE DISPOSITIF EXPERIMENTAL: IL EST CONSTITUE D'UNE HELICE DE 4 M DE LONG, DE 4 SONDES MOBILES POUR LE CONTROLE ET LA MESURE DE LA TURBULENCE, D'UN CANON POUVANT TRAVAILLER EN MODE CONTINU OU PULSE. IL EST SUIVI D'UN DISPOSITIF DE CONTROLE DE LA TEMPERATURE DU FAISCEAU ET D'UN ANALYSEUR TROCHOIDAL POUR LA MESURE DE LA DISTRIBUTION ENERGETIQUE DES ELECTRONS DU FAISCEAU. ENFIN NOUS PRESENTONS LES MESURES DES PARAMETRES LINEAIRES DU TUBE ET COMME TEST DE VALIDITE LE CAS DE L'INTERACTION D'UN FAISCEAU MONOCINETIQUE AVEC UNE ONDE

Available in PDF, EPUB and Kindle. Book excerpt: The present book contains the proceedings of the workshop "Plasma Technology and Applications" which was held at 11 Ciocco (Lucca-Italy) during 5-6 July 1991. The workshop was organized just before ICPIG XX to emphasize the role of plasma physics and plasma chemistry in different fields of technology. Topics cover different applications such as lamps, plasma treatment of materials (etching, deposition, nitriding), plasma sources (microwave excitation, negative ion sources) and plasma destruction of pollutants. Several chapters deal with basic concepts in plasma physics, non equilibrium plasma modeling and plasma diagnostics as well as with laser interaction with solid targets. The authors gratefully acknowledge the financial support provided by university of Bari (Italy) and by CNR (Centro di Studio per la Chimica dei Plasmi, Istituto di Fisica Atomica e Molecolare (IFAM) and Progetto Finalizzato Materiali Speciali per Tecnologie Avanzate) as well as the sponsorship of ENEA.

Download or read book Interfacial Phenomena and the Marangoni Effect written by M. G. Velarde and published by Springer. This book was released on 2014-05-04 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marangoni (1878), provided a wealth of detailed information on the effects of variations of the potential energy of liquid surfaces and, in particular, flow arising from variations in temperature and surfactant composition. One aspect of this science is seen today to bear on important phenomena associated with the processing of modern materials. The role of the basic effect in technology was probably first demonstrated by chemical engineers in the field of liquid-liquid extraction. Indeed, phenomena attributable to Marangoni flows have been reported in innumerable instances relevant to modern technologies, such as in hot salt corrosion in aeroturbine blades; the drying of solvent-containing paints; the drying of silicon wafers used in electronics; in materials processing, particularly in metallic systems which have been suspected to demonstrate Marangoni flows.

Download or read book Water Bears The Biology of Tardigrades written by Ralph O. Schill and published by Springer. This book was released on 2019-02-14 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offering extensive information on tardigrades, this volume begins with a chapter on the history of tardigrades, from the first description by Goeze in 1773, until 1929, when the most comprehensive monographic approach by E. Marcus was published. Tardigrades’ organ systems, including their integument, body cavity, digestive, muscular, nervous and reproductive systems, as well as their overall external morphology, are summarized in the second chapter. Subsequent chapters present the current state of knowledge on tardigrade phylogeny, biogeography, paleontology, cytology and cytogenetics. In addition, the book provides insights into the ecology of tardigrades in marine, freshwater and terrestrial habitats. The reproduction, development and life cycles are summarized and the extraordinary environmental adaptations of encystment and cyclomorphosis, desiccation tolerance, freezing tolerance and radiation tolerance are discussed in detail. Further chapters provide an overview of key approaches in molecular tardigrade studies and describe techniques for sampling and sample processing. The book closes with a list of tardigrade taxa up to a sub-generic level, including the type species of each genus, the numbers of lower taxa in each taxon, and the main environments in which the taxa were found. Given its depth of coverage, the volume offers an invaluable resource for scientists from various disciplines who plan to research tardigrades, and for all others who are interested in these fascinating animals.

Download or read book Progress in New Cosmologies written by H.C. Arp and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hidden Hypotheses Behind the Big Bang It is quite unavoidable that many philosophical a priori assumptions lurk behind the debate between supporters of the Big Bang and the anti-BB camp. The same battle has been waged in physics between the determinists and the opposing viewpoint. Therefore, by way of introduction to this symposium, I would like to discuss, albeit briefly, the many "hypotheses", essentially of a metaphysical nature, which are often used without being clearly stated. The first hypothesis is the idea that the Universe has some origin, or origins. Opposing this is the idea that the Universe is eternal, essentially without beginning, no matter how it might change-the old Platonic system, opposed by an Aristote lian view! Or Pope Pius XII or Abbe Lemaitre or Friedmann versus Einstein or Hoyle or Segal, etc. The second hypothesis is the need for a "minimum of hypotheses" -the sim plicity argument. One is expected to account for all the observations with a mini mum number of hypotheses or assumptions. In other words, the idea is to "save the phenomena", and this has been an imperative since the time of Plato and Aristotle. But numerous contradictions have arisen between the hypotheses and the facts. This has led some scientists to introduce additional entities, such as the cosmologi cal constant, dark matter, galaxy mergers, complicated geometries, and even a rest mass for the photon. Some of the proponents of the latter idea were Einstein, de Broglie, Findlay-Freundlich, and later Vigier and myself.
