Aurora and Kosmos grades are HSS alloys used for the manufacturing of rolling mill work rolls for early finishing stands of Hot Strip Mills. Both alloys were metallurgically assessed using Electron Microscopy, X Rays analysis on carbides and Differential Thermal Analysis. These methods allow a better understanding of the behaviour of the studied alloys during solidification and cooling. Some mechanical tests were also performed. A connection between the laboratory results and the performance in operation of both grades is performed. The strong metallurgical differences especially as concern the nature and amount of carbides allow to explain the good behaviour in service of Aurora. [less ▲]

L'ozone possède des propriétés intéressantes tant dans le domaine médical que dans le domaine de la dentisterie. Ce gaz est capable d'éradiquer un certain nombre de bactéries, de virus et de champignons après seulement 5 secondes de son application. Depuis quelques années, la firme Kavo propose un disposif (HealOzone®) générateur d'ozone spécialement conçu pour traiter les lésions carieuses non cavitaires. Cet article fait le point sur les connaissances actuelles concernant l'utilisation de l'ozone dans le traiement des caries débutantes. [less ▲]

A more rational use of metallic materials for advanced applications (such as for example in aeronautics or fine mechanics) requires to generate the optimal microstructures through the control of the elaboration and fabrication processes. In this context, the description of the critical parameters of the microstructure of the metallic materials, which influence the mechanical properties, is necessary. This step requires the knowledge of the thermically and thermomecanically activated phenomenons (phase transformation, recrystallisation,...). The interpretation and the synthesis of these observations are integrated within physical models which provide the elements necessary to the development of the physical or mathematical macroscopic model. This paper will develop one example of the laboratory MMS researches (Special Metallic Materials) concerning the study of the physicochemical mechanisms controlling the microstructural genesis and the optimization of the mechanical properties. In the case of nanostructured alpha/beta titanium alloys, bonds between mechanical properties and active microstructural elements will be presented. [less ▲]

Since the end of 2000, a continuous sampling to monitor PCDDs and PCDFs emission was implemented on the 11 municipal waste incineration ovens in Walloon Region, to check the compliance with the EU emission limit value, 0.1 TEQ ng/Nm³. For this purpose, uncertainty estimation is one of the most crucial points for decision making. The sampling and analytical uncertainty was estimated by two different ways: 1. Identification and quantification of the major contributions through QA/QC data (type A evaluation) or by other sources (type B evaluation), 2. Direct assessment through specific duplicate measurements. Both ways were found to give results in good agreement, with an extended uncertainty of about 30 to 40%, depending on the congener, with a coverage factor k=2. [less ▲]

We construct simple portfolios of hedge funds whose performance characteristics dominate those of funds of funds using three different measures: the alpha, the Sharpe ratio and the Information ratio. Portfolios made up of non-directional funds with the highest Information ratios and/or Sharpe ratios are likely to exhibit a significant amount of persistence and continue to dominate the best funds of funds on all three performance measures. The large risk exposure of directional hedge fund strategies, however, makes them less likely to dominate funds of funds, even when combined with non-directional hedge funds strategies. Overall, these results seem to imply that the extra layer of fees paid to fund of fund managers are largely unmerited, as we can create portfolios of funds, using simple portfolio construction rules and readily available market information, that greatly outperform the best Fund of Funds.

ABSTRACT: The paper examines what it means to adopt a relational perspective in the study of animal and human communication. First it states that the informational view which dominates the study of animal communication leads to cut apart the biological, the cognitive and the social parts of social communication. When it comes to human nonverbal communication, it is difficult then to articulate its biological and the cul¬tural dimensions. Following Ingold I argue that in order to go beyond the “natural pattern vs cultural rules or meaning” conception of human nonverbal communication, we need to rely on a relational view. But what is a relational view in the study of communication? In the final part of the paper, I suggest that social relationships are both subjective and objective entities and, drawing on an original paper by Kaufmann and Clément (2008, in press), I offer a hypothesis on how social communication could operate to objectively and subjectively organize the construction of social relationships.

We study the coherent flow of interacting Bose-condensed atoms in mesoscopic waveguide geometries. Analytical and numerical methods, based on the mean-field description of the condensate, are developed to study both stationary as well as time-dependent propagation processes. We apply these methods to the propagation of a condensate through an atomic quantum dot in a waveguide, discuss the nonlinear transmission spectrum and show that resonant transport is generally suppressed due to an interaction-induced bistability phenomenon. Finally, we establish a link between the nonlinear features of the transmission spectrum and the self-consistent quasibound states of the quantum dot. [less ▲]

In the literary papyri, the presence of a final, initial, or noted on a label title, not only identifies certainly the contents by giving the ancient name of the work, but is often also, with other codicologic peculiarities, the indication of a copy of library. Do the 22 Hippocratic papyri present an indication of this kind? The author tries to answer these questions by examining not only Hippocratic papyri, but also several adespota where are quoted some titles of Hippocratic treatises, sometimes accompanied with the name of their author.
