This book was released on 1994 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ETUDE CONCERNE LA LUBRIFICATION LIQUIDE DES CONTACTS HERTZIENS EN AMBIANCE SPATIALE. LES DIFFICULTES PROVIENNENT PRINCIPALEMENT DES EFFETS DE LA FAIBLE PRESSION AMBIANTE. CES EFFETS LIMITENT LE CHOIX DES LUBRIFIANTS ET AMPLIFIENT LES CONSEQUENCES DES DEFAILLANCES DE LA LUBRIFICATION QUI SE TRADUISENT IMMEDIATEMENT PAR DES SOUDURES FROIDES QUI ENTRAINENT LE BLOCAGE DES MECANISMES. POUR SE PREMUNIR CONTRE CETTE AVARIE, IL EST NECESSAIRE DE SEPARER LES CORPS EN CONTACT OU PREMIERS CORPS, C'EST LE ROLE DU LUBRIFIANT OU TROISIEME CORPS. LORSQUE POUR DES RAISONS, DE CINEMATIQUE, DE GEOMETRIE, DE CHARGE, DE VITESSE..., UN FILM SEPARATEUR NE SE FORME PAS, DES PALLIATIFS DOIVENT ETRE TROUVES, C'EST L'OBJECTIF DE CE TRAVAIL. POUR CELA ET A PARTIR D'UN TRIBOMETRE EXISTANT, UN DISPOSITIF A ETE CONCU POUR SIMULER ET VISUALISER SOUS VIDE LA PRESENCE D'UN FILM DE LUBRIFIANT DANS DES CONTACTS FONCTIONNANT DANS LES CONDITIONS DES MECANISMES SPATIAUX. PARTANT DE LA CONDITION IDEALE DE SEPARATION QUI EST LA LUBRIFICATION ELASTOHYDRODYNAMIQUE, LES SIMULATIONS ONT PERMIS D'EVALUER LES EFFETS DE LA MICRO-GEOMETRIE ET DE LA VITESSE DES PREMIERS CORPS, DE LA VISCOSITE, DE LA MOUILLABILITE ET DE LA GRANULOMETRIE D'ADDITIFS SOLIDES DANS LE TROISIEME CORPS. LES PALLIATIFS PORTENT SUR LES TROIS ELEMENTS DU TRIPLET TRIBOLOGIQUE: LE MECANISME, ADAPTATION DE LA CINEMATIQUE; LES PREMIERS CORPS, ADAPTATION DE LEUR NATURE ET DE LEUR MICRO-GEOMETRIE; LE TROISIEME CORPS, ADDITIVATION ET CRITERES D'ELABORATION D'UN LUBRIFIANT SPECIFIQUE

IL EST CONCENTRE SUR L'ETUDE DU LUBRIFIANT, EN PARTICULIER SUR SON APTITUDE A POUVOIR REALIMENTER LES ZONES DE CONTACT. L'APPROCHE A ETE SCINDEE EN TROIS CONTRIBUTIONS PRINCIPALES : - TOUT D'ABORD NOUS AVONS ISOLE LE TROISIEME CORPS FLUIDE ET ETUDIE SON COMPORTEMENT RHEOLOGIQUE. L'INFLUENCE DES DIFFERENTS COMPOSANTS DES LUBRIFIANTS SUR LA VISCOSITE APPARENTE, LE SEUIL D'ECOULEMENT OU LEURS PROPRIETES ELASTIQUES A ETE MONTREE ET EXPLICITEE, - LES INTERACTIONS LUBRIFIANTS/SURFACES ONT ETE ETUDIEES A TRAVERS DES EXPERIENCES DE MIGRATION THERMOCAPILLAIRE, QUI CONSTITUENT UNE SOURCE IMPORTANTE DE DESALIMENTATION. DES COMPORTEMENTS TRES DISTINCTS ONT ETE NOTES POUR LES DEUX HUILES DE BASE. LES MIGRATIONS OBSERVEES DANS LE CAS DE SUSPENSIONS SONT RESTEES BEAUCOUP PLUS LIMITEES. - ENFIN, ON S'EST INTERESSE AU FONCTIONNEMENT D'UN CONTACT LUBRIFIE ET DE SON VOISINAGE. LES MECANISMES DE REALIMENTATION DES SUSPENSIONS ET DE LEURS HUILES DE BASE ONT ETE OBSERVES. IL A ETE EGALEMENT MONTRE QUE LES PARTICULES PRESENTES DANS LES SUSPENSIONS PEUVENT APPORTER UN RELAIS EFFICACE A LA LUBRIFICATION LIQUIDE. FINALEMENT, A TRAVERS LA TRANSPOSITION DE CES ACQUIS ANALYTIQUES A L'ETUDE DE LA LUBRIFICATION FLUIDE DES ROULEMENTS COMPLETS, ON EST EN MESURE D'UNE PART, D'EN AMELIORER LE FONCTIONNEMENT ET D'AUTRE PART, DE PROPOSER D'AUTRES THEMES DE RECHERCHE DANS CE DOMAINE.

Available in PDF, EPUB and Kindle. Book excerpt: Wilhelm Reich's final publication, Contact With Space contains the result of six years of intensive research and field work: a natural scientific account of and the basis of practical measures for combating the DOR emergency. This volume is an exposition of the newest developments in the technology of Cosmic Orgone Engineering, which involve the use of "Spacegun," an extension of the cloudbuster made possible by the discovery of ORUR.During Reich's scientific expedition to southern Arizona (1954-1955)--which he documents in this book--it was Cosmic Orgone Engineering that caused desert land to turn green with prairie grass. Here Reich submits a natural scientific explanation of the metabolism of the Life Energy, a study which goes into the nature of primal vegetation, and the nature of dying or death of vegetation, i.e., desert development.Nature being one, Contact With Space examines the new basic energetic facts brought into the open by the Oranur Experiment in terms of the various branches of science into which they ramify: biophysics, Oranur medicine, astrophysics, meteorology, chemistry and pre-atomic chemistry, space technology, man's reactions to these events, etc. It also deals with the methods of the functional scientist.Written under unrelenting attack from conspiratorial commercial interests, this book gives some of the background into the difficult social and physical milieu in which this research was done, and conveys the excitement of the adventures that began the cosmic or "atomic" age.

Book Synopsis Shakespeare and Costume in Practice by : Bridget Escolme
Download or read book Shakespeare and Costume in Practice written by Bridget Escolme and published by Springer Nature. This book was released on 2020-12-23 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the role of costume in Shakespeare production? Shakespeare and Costume in Practice argues that costume design choices are central not only to the creation of period setting and the actor’s work on character, but to the cultural, political, and psychological meanings that the theatre makes of Shakespeare. The book explores questions about what the first Hamlet looked like in his mourning cloak; how costumes for a Shakespeare comedy can reflect or critique the collective nostalgias a culture has for its past; how costume and casting work together to ask new questions about Shakespeare and race. Using production case studies of Hamlet, Much Ado About Nothing, and The Tempest, the book demonstrates that costume design can be a site of experimentation, playfulness, and transgression in the theatre – and that it can provoke audiences to think again about what power, race, and gender look like on the Shakespearean stage.
