141	Influence of Gas Density and Plug Diameter on Plume Characteristics by Ladle Stirring Riabov, Dmitrii, Gain, Muhammad Murtaza, Kargul, Tomasz, Volkova, Olena 10 July 2024 (has links) The paper presents new results concerning the influence of the gas density and porous plug diameter on the nature of liquid steel stirring with an inert gas in the ladle. The tests were carried out on a cold model of a 30t ladle using particle image velocimetry (PIV) with a high-speed camera to analyse the plume zone formed during the supply of argon and helium as a stirring gas. The similarity criteria for the investigation of stirring processes in cold model in the past were discussed and compared. The modified Morton number was used in this paper to relate the gas flow rate in the model with real objects. The presented results constitute complete documentation of the influence of the plug diameter and gas density on the size of formed gas bubbles and the velocity of gas bubbles rising in different zones of the plume, plume, and spout geometry, including the expansion angle, spout height, open eye area, and gas hold-up. info:eu-repo/classification/ddc/620 ddc:620 Stahl Schmelzen Inertgas Argon Helium Particle-Image-Velocimetry
142	Ariadne’s Thread - memory, interconnection and the poetic in contemporary art Fries, Katherine January 2008 (has links) Master of Visual Arts / This Dissertation explores the metaphor of Ariadne’s thread in terms of interconnection, when an element from the everyday is used as a locus linking broader concepts of time and space. Such experiences and associations are reflected in the work of Louise Bourgeois, Eva Hesse, Doris Salcedo, Lucio Fontana, Richard Tuttle, Mona Hatoum, Simone Mangos, Anya Gallaccio and Yoshihiro Suda. In relation to my own work, the metaphor of interconnecting thread allows a sense of freedom and journey of discovery. My studio and related research are closely aligned in developing my understanding of interconnection, through my studio process of making and continuing experiences of looking at and interpreting others artists’ work. contemporary art Ariadne’s thread poetic memory interconnection sculpture painting installation photography Kath Fries drawing The Greek myth of Ariadne’s thread The metaphor of the labyrinth Threads, webs and narratives The Fates of ancient Greece Spiderwoman creation myths Louise Bourgeois Eva Hesse Tracing scars, cracks and ruptures Doris Salcedo Lucio Fontana Richard Tuttle Interwoven Memories Mona Hatoum Simone Mangos Anya Gallaccio Yoshihiro Suda the everyday in contemporary art slumbering artwork Life-support Dancing with Silence Shibboleth Wall whispers Unfurl I wanted to tell you To have and to hold Mirror, Mirror Encroach

144	La condition juridique des personnes privées de liberté du fait d'une décision administrative / The legal status of persons deprived of liberty by an administrative decision Boutouila, Nawal 09 July 2014 (has links) En empruntant une démarche prospective, l’objectif de cette contribution est de mettre en lumière l’existence d’une évolution de la condition juridique des personnes privées de liberté du fait d’une décision administrative. Si pendant longtemps l’obligation de préserver l’ordre public a été présentée comme conférant de nombreuses prérogatives à l’administration, elle doit désormais être décrite comme une mission de service public devant s’accomplir conformément à un modèle de comportement, sans toutefois que l’on puisse aujourd’hui évoquer l’existence de véritables sujétions à la charge de l’administration. Si cette évolution a été rendue possible, c’est en grande partie grâce à de «nouveaux contre-pouvoirs» qui ont contribué au renforcement de leur protection en participant plus ou moins directement à l’identification des obligations que toute administration qui prend en charge une personne privée de liberté devrait respecter et en concourant à leur défense. / By taking a prospective approach, the main of this work is to highlight the existence of an evolution of the legal status of persons deprived of their liberty for an administrative decision. Though the obligation to preserve public order has long been introduced as granting the administration many prerogatives, it must from now on to be equally described as a public-service mission that should be accomplished in accordance with a particular behavior model, without however, always mentioning the presence of actual constraints at the expense of the administration because of the numerous shortcomings currently affecting the protection system. Presumably, if this improvement has been made possible, it is in mainly due to “this new opposing-force concept” that has contributed to strengthening theirs protection especially by participating in the identification of the obligations that should be respected by all administrations which have to take care of a person deprived of liberty.
