This book was released on 2000 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: DIFFERENTS ASPECTS DE L'INTERACTION D'UNE IMPULSION ULTRA-COURTE ET ULTRA-INTENSE AVEC UN PLASMA SOUS-DENSE ONT ETE ETUDIES ANALYTIQUEMENT ET NUMERIQUEMENT. CES ETUDES PRESENTENT UN INTERET POUR L'ACCELERATION LASER DE PARTICULES DANS LES PLASMAS, LES LASERS A RAYONS X, LA GENERATION D'HARMONIQUES D'ORDRE ELEVE, LE CONCEPT D'ALLUMEUR RAPIDE POUR LA FUSION PAR CONFINEMENT INERTIEL. ON A UTILISE LE CODE PARTICULAIRE RELATIVISTE WAKE DEVELOPPE PRECEDEMMENT A L'ECOLE POLYTECHNIQUE. CE CODE A ETE MODIFIE AU COURS DE LA THESE POUR TRAITER LE MOUVEMENT DES IONS, POUR CALCULER DES TRAJECTOIRES D'ELECTRONS TESTS, ET POUR INCLURE DES DIAGNOSTICS DIVERS SUR LES CHAMPS ET LES PARTICULES. LES SUJETS TRAITES DANS CETTE THESE SONT LES SUIVANTS : L'ACCELERATION DE PHOTONS DANS LE SILLAGE D'UNE IMPULSION LASER COURTE ET INTENSE, LA VITESSE DE PHASE DE L'ONDE PLASMA DANS LE SILLAGE D'UNE IMPULSION LASER AUTO-MODULEE, LA CANALISATION RELATIVISTE D'IMPULSION LASER DE DUREE DE L'ORDRE DE LA PERIODE PLASMA, LA DYNAMIQUE IONIQUE DANS LE SILLAGE, LE DEFERLEMENT. ENFIN ON A SIMULE 3 EXPERIENCES DE PROPAGATION D'ONDE LASER ET D'ACCELERATION D'ELECTRONS. VOICI LES PRINCIPAUX RESULTATS DE LA THESE : LA REDUCTION DE LA VITESSE DE PHASE DE L'ONDE PLASMA DANS LE CAS D'UNE IMPULSION LASER AUTO-MODULEE NE JOUE QUE DANS LE CAS D'UN CANAL PREFORME POUR LE GUIDAGE DE L'ONDE LASER. ON A TROUVE DES STRUCTURES SELF-SIMILAIRES POUR DECRIRE LE GUIDAGE RELATIVISTE D'UNE IMPULSION COURTE DANS UN PLASMA. ON A DEMONTRE LA PROPAGATION AUTO-GUIDEE D'IMPULSION INITIALEMENT GAUSSIENNES DE QUELQUES PERIODES PLASMA. ON A MONTRE QUE LA FORCE PONDEROMOTRICE DE L'ONDE PLASMA EXCITEE PAR L'IMPULSION LASER FORME UN CANAL ET LE DEFERLEMENT DANS CE CANAL A ETE ANALYSE EN DETAIL. LES EFFICACITES DE L'ACCELERATION D'ELECTRONS DANS LE CHAMP LASER ET DANS L'ONDE PLASMA ONT ETE COMPAREES. LE DECALAGE EN FREQUENCE D'UNE SONDE SE PROPAGEANT DANS LE SILLAGE PLASMA A ETE ETUDIE DANS DES CONDITIONS CORRESPONDANT A DES EXPERIENCES ACTUELLES.

This book was released on 1996 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: ON A DEVELOPPE AU COURS DE CE TRAVAIL UN CODE DE SIMULATION NUMERIQUE BIDIMENSIONNEL CYLINDRIQUE QUI DECRIT L'INTERACTION D'IMPULSIONS LASER ULTRA-BREVES ET ULTRA-INTENSES AVEC DES GAZ OU DES PLASMAS PEU DENSES. DE PLUS, POUR PERMETTRE UNE COMPARAISON DIRECTE DES PREVISIONS THEORIQUES AVEC LES RESULTATS EXPERIMENTAUX, LES DIAGNOSTICS PRINCIPAUX DE LA PHYSIQUE EXPERIMENTALE DE L'INTERACTION LASER-PLASMA ONT ETE SIMULES. LE NOYAU DU CODE ADOPTE UNE DESCRIPTION PARTICULAIRE DU MILIEU DE PROPAGATION, UNE APPROXIMATION PARAXIALE POUR LA PROPAGATION DE L'ONDE ELECTROMAGNETIQUE ET UNE APPROXIMATION QUASI-STATIQUE POUR LA DESCRIPTION DE L'ACTION DE L'ONDE SUR LE MILIEU. SUR CE NOYAU ON A GREFFE UN MODULE POUR DECRIRE LA FORMATION DU PLASMA PAR IONISATION TUNNEL D'UN MILIEU GAZEUX INITIAL. ENSUITE DES IMPULSIONS LASER DE FREQUENCE DOUBLE ONT ETE AJOUTEES AU CODE AFIN DE SIMULER LA PROPAGATION DE SONDES ELECTROMAGNETIQUES COLINEAIRES AU FAISCEAU PRINCIPAL. D'AUTRES DIAGNOSTICS, TELS QUE LA DIFFUSION THOMSON A 90 DE L'AXE OPTIQUE, ONT ETE INTRODUITS. ENFIN, UN DEUXIEME CODE NUMERIQUE A ETE ELABORE POUR LA REPRISE ET LA PROPAGATION DANS LE VIDE DES ONDES ELECTROMAGNETIQUES. CES DERNIERES ONT DONC PU ETRE ANALYSEES DANS LA REGION DITE DU CHAMP LOINTAIN, C'EST-A-DIRE A L'ENDROIT OU LES DETECTEURS REELS SONT PLACES. AVEC LES OUTILS NUMERIQUES AINSI DEVELOPPES ON A PU REPRODUIRE DES RESULTATS EXPERIMENTAUX DIVERS, AVEC UNE PRECISION INHABITUELLE POUR LES SIMULATIONS DE LA PHYSIQUE DE L'INTERACTION LASER-PLASMA. CES RESULTATS ONT FOURNI DES INDICATIONS IMPORTANTES POUR L'INTERPRETATION ET LA CONCEPTION D'EXPERIENCES DE SILLAGE LASER ET D'AUTOFOCALISATION RELATIVISTE.

Book Synopsis Calcium Entry Blockers in Cardiovascular and Cerebral Dysfunctions by : T. Godfraind
Download or read book Calcium Entry Blockers in Cardiovascular and Cerebral Dysfunctions written by T. Godfraind and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2 The free internal Ca+ concentration in human red cells is set according to the leak 2 and-pump principle: There is a finite passive Ca+ influx at the physiological 2 2 Ca+ -gradient across the membrane which is compensated by Ca+ pumping in the outward direction with a rate given by the degree of saturation of the A TP-fuelled Ca 2 pump at the steady-state internal Ca+ concentration. Simons (1982) recently devised a method allowing the measurement of the steady 2 2 state internal Ca+ concentration. Cells are suspended in media of different Ca+ con 2 2 tent whose Ca+ concentration is monitored by a Ca+ -selective electrode. When the cells are lysed (by digitonin) there is an upward or downward deflection of the elec 2 trode signal. At the point of zero deflection, the cellular Ca+ concentration equals that 2 of the medium. The result is, that in fresh human red blood cells the Ca+ concentra tion is ;;;; O.4,uM (this is an upper estimate; the true value may be considerably lower).

Download or read book Hypersonic Flow Theory written by Wallace Hayes and published by Elsevier. This book was released on 2012-12-02 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hypersonic Flow Theory presents the fundamentals of fluid mechanics, focusing on the hypersonic flow theory and approaches in theoretical aerodynamics. This book discusses the assumptions underlying hypersonic flow theory, unified supersonic-hypersonic similitude, two-dimensional and axisymmetric bodies, and circular cylinder. The constant-streamtube-area approximation, streamtube-continuity methods, and tangent-wedge and tangent-cone are also deliberated. This text likewise covers the similar laminar boundary layer solutions, bluntness induced interactions on slender bodies, and free molecule transfer theory. The dynamics of hypersonic flight or hypersonic wing theory, magnetohydrodynamic theory, or any developments involving treatment of the Boltzmann equation are not included. This publication is intended for hypersonic aerodynamicists, students, and researchers conducting work on the hypersonic flow phenomena.
Book Synopsis Organic Solid-State Lasers by : Sébastien Forget
Download or read book Organic Solid-State Lasers written by Sébastien Forget and published by Springer. This book was released on 2013-07-03 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic lasers are broadly tunable coherent sources, potentially compact, convenient and manufactured at low-costs. Appeared in the mid 60’s as solid-state alternatives for liquid dye lasers, they recently gained a new dimension after the demonstration of organic semiconductor lasers in the 90's. More recently, new perspectives appeared at the nanoscale, with organic polariton and surface plasmon lasers. After a brief reminder to laser physics, a first chapter exposes what makes organic solid-state organic lasers specific. The laser architectures used in organic lasers are then reviewed, with a state-of-the-art review of the performances of devices with regard to output power, threshold, lifetime, beam quality etc. A survey of the recent trends in the field is given, highlighting the latest developments with a special focus on the challenges remaining for achieving direct electrical pumping of organic semiconductor lasers. A last chapter covers the applications of organic solid-state lasers.
