Over the last fifteen years, child's pain has become one of our major concerns. In spite of this evolution, it remains one of the most frequent complications after ambulatory surgery. It is thus essential to implement all the resources we have at our disposal in order to optimize pain management. This can be obtained by basing our strategy on the concept of multimode analgesia. It is consequently essential that each team can achieve its own quality program; the corollary will be the development of clear recommendations for the parents with a systematic analgesics regulation at home and the possibility to resort to the family doctor or to the ambulatory centre in the event of persistence of pain.

The new set of RILEM recommendations specifies test methodologies for determining the different mechanical properties of concrete at high temperatures. The new set of recommendations applies to all types of concrete used in construction, including high strength concrete. The recommendations specify that the environmental and testing conditions associated with service or accident conditions of structural concrete at high temperature need to be considered, while using these building materials for construction activities. The recommendations are also applicable to concrete in the temperature range of 20°C-750°C. The recommendations also contain several results of the experimental investigations conducted, to examine the behavior of concrete at high temperature that depend on test conditions. [less ▲]

In this paper, I present a general discussion of several astrophysical processes likely to play a role in the production of non-thermal emission in massive stars, with emphasis on massive binaries. Even though the discussion will start in the radio domain where the non-thermal emission was first detected, the census of physical processes involved in the non-thermal emission from massive stars shows that many spectral domains are concerned, from the radio to the very high energies. First, the theoretical aspects of the non-thermal emission from early-type stars will be addressed. The main topics that will be discussed are respectively the physics of individual stellar winds and their interaction in binary systems, the acceleration of relativistic electrons, the magnetic field of massive stars, and finally the non-thermal emission processes relevant to the case of massive stars. Second, this general qualitative discussion will be followed by a more quantitative one, devoted to the most probable scenario where non-thermal radio emitters are massive binaries. I will show how several stellar, wind and orbital parameters can be combined in order to make some semi-quantitative predictions on the high-energy counterpart to the non-thermal emission detected in the radio domain. These theoretical considerations will be followed by a census of results obtained so far, and related to this topic. These results concern the radio, the visible, the X-ray and the gamma-ray domains. Prospects for the very high energy gamma-ray emission from massive stars will also be addressed. Two particularly interesting examples-one O-type and one Wolf-Rayet binary-will be considered in details. Finally, strategies for future developments in this field will be discussed. [less ▲]

A new load shedding scheme against long-term voltage instability is proposed. It uses a set of distributed controllers, each monitoring transmission voltages in a zone and controlling a group of related loads. Each controller acts in closed-loop, shedding amounts that vary in magnitude and time according to the evolution of its monitored voltage. The whole system can operate without information exchange between controllers, the latter being implicitly coordinated through network voltages. The operation, design and robustness features are illustrated through simulations of a real system. [less ▲]

In seagrass meadows, several groups of vagile invertebrates are well known to perform a nocturnal rise from the lower layers of the meadow to the foliar stratum. This vertical migration is generally regarded as a defense mechanism against predation by diurnal fishes, as well as a mean to maximize the exploitation of trophic resources offered by the meadow. Here, we focused on the amphipods from a Mediterranean Posidonia oceanica meadow. We sampled the community present in the meadows of Calvi Bay (NW Corsica) using two different techniques (hand-towed net and litter collecting). Samples were taken at two seasons, during both night and daytime. Our results confirm the nocturnal rise to the foliar stratum. Combined to an analysis of the recent literature, they also tend to show that amphipods spend the daytime not in the matte itself, as it has been proposed in the past, but in the thin layer of Posidonia litter present at the interface between the foliar stratum and the root/rhizome system. This would emphasize the role of the litter cover in the complexity of the habitat within the meadow, and therefore in the vagile invertebrate community structure and the functioning of the whole meadow as an ecosystem.

An implementation of the event tree approach is proposed to determine possible sequences of cascading failures with severe impact on a given power system. The algorithm takes into account protection systems hidden failures and transmission system equipments overload. At each level of the event tree development, the sequence probability order is computed and a filtering tool is used to identify possible harmful sequence. These are furthermore analysed with a time domain simulation tool in order to assess their impact on the power system. This paper contains the description of the event tree algorithm as well as examples of its practical application on the Nordic32 test system. [less ▲]

Inspired from the experience of river contract in Wallonia (Belgium), the implementation of a first river contract has been initiated in a West-African country, Burkina Faso, since 2003. In the program of actions approved by the river committees in December 2005, the protection of water resources and grounds was taken into account. The first realized actions contributed to slow down the degradation of the ecosystems by recreating a space buffer between the river and the cultivated zones. A first project of restoration of the gallery forest alongside the stream was implemented to fight against desertification. This project arouses a strong mobilization of the local actors and demonstrates that such a contractual tool of participative management can make an interesting contribution in favour of an integrated management of waters and grounds. In a river contract, these two resources are associated in a common reflection which transcends still too often sector-based policies. [less ▲]

La démarche de Fourest est mise en relation à la fois avec celle des peintures «monochroïdales » d’Alphonse Allais et avec celle du « sonnet en yx » de Stéphane Mallarmé. Elle est finalement perçue dans toute son ambiguïté, entre la mise en cause radicale de la poésie et la facétie fin de siècle. [less ▲]

In mammals, thyrotropin, or thyroid-stimulating hormone (TSH), assay is used for the diagnosis of primary hypothyroidism. Hypothyroidism is the most common type of thyroid disorder in cattle. The aim of this study was to develop and validate, under physiologic and pathologic conditions, a radioimmunoassay (RIA) for bovine TSH (bTSH). Double RIA was performed with purified bTSH and specific bovine antiserum. Laboratory validation included research of minimal detection limit, accuracy, and reproducibility. The physiologic validation included a thyrotropin-releasing hormone (TRH) challenge performed on euthyroid cows and a follow-up of bTSH concentration over a 24-hour period. Furthermore, bTSH concentration was assayed in a large population of healthy dairy and beef cows to define reference interval. The pathologic validation was made by assaying bTSH and thyroid hormones on healthy and goitrous newborn calves. The minimum detection limit (MDL) for bTSH assay was 1.3 microU/ml. The recovery was 101% to 106%. The intra- and interassay coefficients of variation (CVs) ranged from 5% to 11% and 11% to 15%, respectively. The RIA covered the whole range of physiologic bTSH values, as shown by bTSH values induced by TRH-challenge. A pulsatile secretion of bTSH was observed, accompanied by a diurnal variation with lower night values than day values. Reference intervals of bTSH ranged from 1.3 to 13.0 microU/ml for beef and dairy breeds. Finally, bTSH easily discriminated goitrous newborn calves from healthy ones, leading to the definition of a cutoff value of 35 microU/ml. The bTSH assay positively reacted to physiologic and pathologic conditions. The accuracy and precision of the RIA were satisfying. [less ▲]

When a droplet is gently laid onto the surface of the same liquid, it stays at rest for a moment before coalescence. The coalescence can be delayed and sometimes inhibited by injecting fresh air under the droplet. This can happen when the surface of the bath oscillates vertically. In this case the droplet basically bounces on the interface. The lifetime of the droplet has been studied with respect to the amplitude and the frequency of the excitation. The lifetime decreases when the acceleration increases. The thickness of the air film between the droplet and the bath has been investigated using interference fringes obtained when the system is illuminated by low-pressure sodium lamps. Moreover, both the shape evolution and the motion of the droplet center of mass have been recorded in order to evidence the phase offset between the deformation and the trajectory. A short lifetime is correlated to a small air-film thickness and to a large phase offset between the maximum of deformation and the minimum of the vertical position of the center of mass. [less ▲]

Vu l’intérêt croissant porté par les entreprises aux aspects sociaux et environnementaux, la présente communication propose une revue des principales contributions montrant l’importance et les enjeux de la prise en compte des dimensions sociales et environnementales (de la RSE) dans les systèmes de contrôle de gestion des entreprises. Plus spécifiquement, face aux limites de nombreux outils pour piloter et mesurer adéquatement l’empreinte sociétale des entreprises, ce papier met en évidence les avantages présentés par la Balanced ScoreCard (BSC), un outil de contrôle de gestion développé par Kaplan et Norton (1992) et mondialement connu, pour prendre en compte ces nouvelles dimensions. Cette communication expose ensuite comment cet outil peut éventuellement être adapté afin de prendre en compte ces nouveaux impératifs (sociaux et environnementaux) dans le système de contrôle de gestion traditionnel de l’entreprise. Deux possibilités sont particulièrement envisagées : le découplage ou l’intégration des aspects sociétaux aux aspects traditionnels. Une analyse critique des principaux enseignements des recherches précédentes ainsi que des différentes possibilités d’adaptation de la BSC clôture finalement ce papier. [less ▲]
