Current Perspectives on Inclusive Education in the Czech Republic

This paper examines the academic literature describing the development of inclusive education programming within the Czech Republic after the Velvet Revolution. Interviews were conducted with special education professionals, who are researching potential benefits of inclusive education. Additionally, observations from an inclusive third grade classroom give further insight into how an inclusive classroom works. Despite some resistance, the Czech Republic is moving in the direction of inclusive education across the country

The HELP inequality on trees

We establish analogues of Hardy and Littlewood's integro-differential equation for Schrödinger-type operators on metric and discrete trees, based on a generalised strong limit-point property of the graph Laplacian

A repulsive atomic gas in a harmonic trap on the border of itinerant ferromagnetism

Alongside superfluidity, itinerant (Stoner) ferromagnetism remains one of the most well-characterized phases of correlated Fermi systems. A recent experiment has reported the first evidence for novel phase behavior on the repulsive side of the Feshbach resonance in a two-component ultracold Fermi gas. By adapting recent theoretical studies to the atomic trap geometry, we show that an adiabatic ferromagnetic transition would take place at a weaker interaction strength than is observed in experiment. This discrepancy motivates a simple non-equilibrium theory that takes account of the dynamics of magnetic defects and three-body losses. The formalism developed displays good quantitative agreement with experiment.Comment: 4 pages, 2 figure

A VLT/FLAMES survey for massive binaries in Westerlund 1 IV. Wd1-5 – binary product and a pre-supernova companion for the magnetar CXOU J1647-45?

Context. The first soft gamma-ray repeater was discovered over three decades ago, and was subsequently identified as a magnetar, a class of highly magnetised neutron star. It has been hypothesised that these stars power some of the brightest supernovae known, and that they may form the central engines of some long duration gamma-ray bursts. However there is currently no consenus on the formation channel(s) of these objects.Aims. The presence of a magnetar in the starburst cluster Westerlund 1 implies a progenitor with a mass ≥40 M⊙, which favours its formation in a binary that was disrupted at supernova. To test this hypothesis we conducted a search for the putative pre-SN companion.Methods. This was accomplished via a radial velocity survey to identify high-velocity runaways, with subsequent non-LTE model atmosphere analysis of the resultant candidate, Wd1-5.Results. Wd1-5 closely resembles the primaries in the short-period binaries, Wd1-13 and 44, suggesting a similar evolutionary history, although it currently appears single. It is overluminous for its spectroscopic mass and we find evidence of He- and N-enrichement, O-depletion, and critically C-enrichment, a combination of properties that is difficult to explain under single star evolutionary paradigms. We infer a pre-SN history for Wd1-5 which supposes an initial close binary comprising two stars of comparable (~ 41 M⊙ + 35 M⊙) masses. Efficient mass transfer from the initially more massive component leads to the mass-gainer evolving more rapidly, initiating luminous blue variable/common envelope evolution. Reverse, wind-driven mass transfer during its subsequent WC Wolf-Rayet phase leads to the carbon pollution of Wd1-5, before a type Ibc supernova disrupts the binary system. Under the assumption of a physical association between Wd1-5 and J1647-45, the secondary is identified as the magnetar progenitor; its common envelope evolutionary phase prevents spin-down of its core prior to SN and the seed magnetic field for the magnetar forms either in this phase or during the earlier episode of mass transfer in which it was spun-up.Conclusions. Our results suggest that binarity is a key ingredient in the formation of at least a subset of magnetars by preventing spin-down via core-coupling and potentially generating a seed magnetic field. The apparent formation of a magnetar in a Type Ibc supernova is consistent with recent suggestions that superluminous Type Ibc supernovae are powered by the rapid spin-down of these objects

COSWIN Logiciel de Maintenance des Equipements de Levage

La section 'Maintenance d'équipements de levage' assure l'entretien préventif et correctif d'un parc de 2800 appareils de levage et de manutention. Cette tâche est effectuée en collaboration avec une entreprise, spécialisée dans la maintenance industrielle. Pour faciliter la gestion des interventions, la section ST-HM-PR dispose depuis 1985 d'un système de gestion de maintenance assistée par ordinateur (GMAO). En 1996, cet ancien système a été remplacé par le logiciel 'COSWIN'. Celui-ci correspond aux besoins de la maintenance des appareils de levage. Sa disponibilité sous la plate-forme 'WINDOWS' rend l'utilisation de la GMAO facile et conviviale. 'COSWIN' travaillant en réseau, la base de données est commune pour tous les utilisateurs et mise à jour en temps réel. Depuis leurs locaux, situés au Technoparc de St. Genis, les opérateurs de l'entreprise contractante ont accès au logiciel par une ligne téléphonique. Le contrôle et le suivi des performances de l'entreprise se fait par l'analyse des différents ratios

Système de contrôle des chargeurs de batteries des chariots électriques de l'anneau SPS

La Section Maintenance d'équipements de levage assure le suivi de 2746 appareils de levage et de manutention répartis en 22 familles. La Section gère également l'achat, l'installation et la mise en service des nouveaux équipements. En Novembre 1996, un système de contrôle des chargeurs de batteries pour les chariots circulant dans l'anneau du SPS a été installé. Ce système nous permet, depuis un ordinateur installé dans nos bureaux, de visualiser les statuts des 47 chargeurs répartis sur les différents points du SPS, de vérifier la courbe de charge de chaque batterie, de déclencher le remplissage en eau distillée, et de démarrer le brassage pneumatique de l'électrolyte. Nous pouvons également programmer les périodes de non-enclenchement de nos chargeurs. Le système enregistre le temps d'utilisation d'un chariot et nous indique sa localisation et son numéro
