Dans "Les Mages hellénisés", Cumont et Bidez ont tenté un compromis entre l'état de l'art contemporain de la rédaction de leur ouvrage et le contenu des sources classiques qu'ils ont collectées. L'examen de ces dernières permet pourtant de douter que les premiers témoins grecs du monde achéménide aient cru en l'historicité récente de Zoroastre. [less ▲]

Since current trends in the transportation, energy or mechanical industries impose increasingly demanding service conditions for metallic parts, metal matrix composites (MMC) are the object of a growing interest. Powder-based laser additive manufacturing, that allows to make parts with complex shapes, appears particularly adapted for the production of MMCs. This paper reviews the current state-of-the-art in the production of MMCs by additive processes, with the aim of assessing the potentials and difficulties offered by these techniques. Two main processing routes are envisaged i.e. (1) the processing of ex-situ composites in which the reinforcing phase as a powder – often of ceramic particles − is directly mixed with the powder of the matrix alloy, and both powders are simultaneously processed by the laser. (2) Alternatively, the reinforcing phase can be produced in-situ by a chemical reaction during the fabrication of the composite. For both processing routes, a careful control is needed to overcome challenges brought e.g. by the behaviour of the reinforcement particles in the laser beam, by changes in laser absorptivity or by the dissolution of the reinforcing particles in the molten metal, in order to produce metal matrix composites with enhanced usage properties.

How do contemporary migrant mothers strategize return to their home countries? And how does the social protections available for their bi-national children in sending and destination countries factor in the decision to return? Through this contribution, we aimed to tackle these questions. We draw from the analysis of two longitudinal migratory careers and argue that our participant’s return decisions were influenced both by their children’s effective access to social protection and their subjective perceptions of ‘good-motherhood’. This Trans-Atlantic comparison shows how different situated-institutional-contexts, cultures of care and motherhood resulted into different patterns of mobility for these women and their families.

Fire disasters are a serious threat to the functionality of the built environment, in particular in densely populated urban areas where city infrastructure systems are under strain. Yet, fire safety issues are still mostly considered at the level of individual elements or buildings, disregarding the global risk for systems’ functionality. In line with the current efforts toward ensuring more resilient cities, this paper presents an overview of urban infrastructure resilience to fire disaster. The definitions of resilience and the quantitative frameworks established for other hazards such as earthquakes are reviewed. Then, the specificities of structural fire engineering are presented and it is shown how resilience frameworks could be applied to fire hazard. Finally, the paper identifies areas where further research efforts are needed. [less ▲]

A systematic study on the presence of bottlenose dolphins (Tursiops truncatus) in the Río Negro Estuary (RNE), Patagonia Argentina, was carried out between the months March – July from 2008 to 2011. Data on the dolphin’s activity patterns were gathered via an Ad Libitum focal group sampling mode accompanying dorsal fin images taken for identification and re-identification of individuals. A total effort of 188 h resulted in 58 h of positive observation of 124 dolphin groups (sightings per unit effort (SPUE) = 0.66 groups/h). Data analysis showed two main activity states for the observed groups, travelling (65%) and foraging (26%). The remaining 9% of the groups were involved in other activity states. The photo-identification effort, which started opportunistically in 2006, resulted in a catalogue of 21 individual dolphins, with a total mean re-identification rate of 9 days (max = 24 days). When comparing these pictures to the existing catalogue of Bahía San Antonio (approximately 200 km west from the study area) dorsal fins of 20 individuals could be positively matched and most (n = 17) could be subsequently re-identified in both areas, indicating their long distance movements along the North Patagonian coast during the austral autumn months. This season coincides with the lowest amount of feeding activity observed in Bahía San Antonio. This study suggests that bottlenose dolphins enter RNE, mainly during autumn, to forage. It appears that the search for food resources may be the trigger for their movement patterns along the North Patagonian coast during this season, at least for certain individuals. More research is needed to accurately confirm this hypothesis. [less ▲]

We examine different aspects of energy conservation in the case of the analytical solution of Ritter for idealized dam break flow in a horizontal frictionless and dry channel. We detail the application of the unsteady Bernoulli equation in this case and highlight that the inertial effects cancel out when averaged over the whole flow region. We also show that the potential and kinetic contributions to the total mechanical energy in the flow region have a distinct and constant relative importance: potential energy accounts for 60 %, and kinetic energy for 40 % of the total mechanical energy. These properties of Ritter solution are rarely emphasized while they may be of practical relevance, particularly for the verification of numerical schemes with respect to their ability to ensure energy conservation.

In this article, we propose a robust statistical approach to select an appropriate error distribution, in a classical multiplicative heteroscedastic model. In a first step, unlike to the traditional approach, we don't use any GARCH-type estimation of the conditional variance. Instead, we propose to use a recently developed nonparametric procedure (Mercurio and Spokoiny, 2004): the Local Adaptive Volatility Estimation (LAVE). The motivation for using this method is to avoid a possible model misspecification for the conditional variance. In a second step, we suggest a set of estimation and model selection procedures (Berk-Jones tests, kernel density-based selection, censored likelihood score, coverage probability) based on the so-obtained residuals. These methods enable to assess the global fit of a set of distributions as well as to focus on their behavior in the tails, giving us the capacity to map the strengths and weaknesses of the candidate distributions. A bootstrap procedure is provided to compute the rejection regions in this semiparametric context. Finally, we illustrate our methodology throughout a small simulation study and an application on three time series of daily returns (UBS stock returns, BOVESPA returns and EUR/USD exchange rates) [less ▲]

Régulièrement recommandé à des fins préventives ou curatives, le repos vocal favorise la récupération dans différentes circonstances. Bon nombre de phonochirurgiens l’incluent dans les soins postopératoires, avant une éventuelle prise en charge orthophonique. Le repos vocal permet également de résorber une simple fatigue ressentie suite à un usage intensif ou inhabituel de la voix, ou peut faire l’objet d’une indication thérapeutique dans le cadre de lésions consécutives aux phonotraumatismes. Compte tenu du manque de données scientifiques et de la diversité des pratiques sur le sujet, il n’est pas toujours aisé de donner des indications claires aux patients, souvent réticents à l’idée de ne pas pouvoir utiliser leur voix pendant une durée prolongée. Basé sur des recherches récentes et sur des expériences cliniques, ce chapitre permet de mieux comprendre l’intérêt du repos vocal et suggère des lignes de conduites quant à la manière de l’organiser [less ▲]

Palaeoecological and archaeological studies have demonstrated that human populations have long inhabited the moist forests of central Africa. However, spatial and temporal patterns of human activities have hardly been investigated with satisfactory accuracy. In this study, we propose to characterize past human activities at local scale by using a systematic quantitative and qualitative methodology based on soil charcoal and charred botanical remains. A total of 88 equidistant test-pits were excavated along six transects in two contrasting forest types in southern Cameroon. Charred botanical remains were collected by water-sieving and sorted by type (wood charcoals, oil palm endocarps, and unidentified seeds). A total of 50 Accelerator Mass Spectrometry 14C dates were also obtained. Results showed that charred macroremains were found at multiple places in the forest, suggesting scattered human activities, which were distributed into two main periods (Phase A: 2300-1300 BP – Phase B: 580 BP to the present). Charred botanical remains indicated two types of land use: (i) domestic, with oil palm endocarps most often associated with potsherds (villages) and (ii) agricultural, with charcoal as probable remnant of slash-and-burn cultivation (fields). Oil palm endocarp abundance decreased with distance from the identified human settlements. Our methodology allowed documenting, at high resolution, the spatial and temporal patterns of human activities in central African moist forests and could be applied to other tropical contexts.
