EXPERIMENTALEMENT, LES REACTIONS ACIDO-BASIQUES AINSI QUE LES CHANGEMENTS DE CONFORMATION MOLECULAIRE DEUX TYPES DE REACTION TRES IMPORTANTES POUR LA CHIMIE DES LIQUIDES PEUVENT EXHIBER DES CINETIQUES POUVANT ETRE ETUDIEES DANS LE CADRE THEORIQUE PROPOSE. DANS CE MEMOIRE, LA THEORIE DES PROFILS DES BANDES RAMAN DES FLUIDES REACTIFS PROPOSEE EST UNE EXTENSION DES THEORIES ADAPTEES AUX FLUIDES NON REACTIFS, (ELABOREES CES DEUX DERNIERES DECADES DANS CE LABORATOIRE). DEUX MODELES THEORIQUES SONT DEVELOPPES POUR PRENDRE EN CONSIDERATION LA REACTION CHIMIQUE. DANS LE PREMIER, CELLE-CI EST SIMULEE PAR UN PROCESSUS MARKOVIEN DISCRET ENTRE DES ETATS BIEN DEFINIS DU SYSTEME. DANS LE SECOND MODELE, LA REACTION EST ALORS SIMULEE PAR UN PROCESSUS MARKOVIEN CONTINU LE LONG DE LA COORDONNEE REACTIONNELLE; CE PROCESSUS EST DECRIT PAR UNE EQUATION DE SMOLUCHOWSKI. LES RESULTATS OBTENUS PAR CES DEUX APPROCHES SONT LES SUIVANTS: LE PREMIER MODELE DE REACTION PERMET DE PRECISER LES MODIFICATIONS SPECTRALES CARACTERISANT L'INFLUENCE DE LA REACTION CHIMIQUE SUR LE PROFIL DE BANDE RAMAN. DE PLUS, L'ANALYSE DE PROFIL PERMET D'OBTENIR QUANTITATIVEMENT LA CONSTANTE DE VITESSE DE LA REACTION ETUDIEE. LES RESULTATS DU SECOND MODELE CONFIRMENT, DANS SES TRAITS ESSENTIELS, CEUX DU PREMIER. CEPENDANT, DANS CE CAS, EN AYANT INTRODUIT UNE DESCRIPTION PLUS FINE DE LA REACTION CHIMIQUE, NOUS AVONS PU METTRE EN EVIDENCE LE ROLE DES PHENOMENES PREREACTIFS SUR LA FORME DES BANDES; LA THEORIE DONNE ALORS UN CADRE EXPERIMENTAL DANS LEQUEL CES PHENOMENES PREREACTIFS POURRONT ETRE ANALYSES

Download or read book Granular Gases written by Thorsten Pöschel and published by Springer Science & Business Media. This book was released on 2001-02-27 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Granular Gases" are diluted many-particle systems in which the mean free path of the particles is much larger than the typical particle size, and where particle collisions occur dissipatively. The dissipation of kinetic energy can lead to effects such as the formation of clusters, anomalous diffusion and characteristic shock waves to name but a few. The book is organized as follows: Part I comprises the rigorous theoretical results for the dilute limit. The detailed properties of binary collisions are described in Part II. Part III contains experimental investigations of granular gases. Large-scale behaviour as found in astrophysical systems is discussed in Part IV. Part V, finally, deals with possible generalizations for dense granular systems.

Download or read book Collected Papers on Wave Mechanics written by Erwin Schrödinger and published by American Mathematical Soc.. This book was released on 2003 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The famous equation that bears Erwin Schrödinger's name encapsulates his profound contributions to quantum mechanics using wave mechanics. This third, augmented edition of his papers on the topic contains the six original, famous papers in which Schrödinger created and developed the subject of wave mechanics as published in the original edition. As the author points out, at the time each paper was written the results of the later papers were largely unknown to him. This edition also contains three papers that were written shortly after the original edition was published and four lectures delivered by Schrödinger at the Royal Institution in London in 1928. The papers and lectures in this volume were revised by the author and translated into English, and afford the reader a striking and valuable insight into how wave mechanics developed.

Download or read book Applied Mineralogy in the Mining Industry written by W. Petruk and published by Elsevier. This book was released on 2000-11-29 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques of performing applied mineralogy investigations, and applications and capabilities of recently developed instruments for measuring mineral properties are explored in this book intended for practicing applied mineralogists, students in mineralogy and metallurgy, and mineral processing engineers. The benefits of applied mineralogy are presented by using in-depth applied mineralogy studies on base metal ores, gold ores, porphyry copper ores, iron ores and industrial minerals as examples. The chapter on base metal ores includes a discussion on the effects of liberation, particle sizes and surfaces coatings of Pb, Cu, Fe, Ca and So4- on the recoveries of sphalerite, galena and chalcopyrite. The chapter on gold discusses various methods of determining the quantities of gold in different minerals, including 'invisible' gold in pyrite and arsenopyrite, so that a balance of the distribution of gold among the minerals can be calculated. This book also discusses the roles of pyrite, oxygen, moisture and bacterial (thiobacillus ferrooxidans) on reactions that produce acidic drainage from tailings piles, and summarizes currently used and proposed methods of remediation of acidic drainage.
