Les troubles du sommeil sont fréquents chez l’enfant et leurs origines sont diverses. Ces troubles ont leur ancrage dans le développement neurophysiologique et psychoaffectif de l’enfant. Les enfants souffrant de troubles du spectre autistique présentent un déficit de sommeil, qui peut durer jusqu’à l’adolescence. Les troubles du spectre autistique comportent des comorbidités multiples, dont des altérations du sommeil. Ils sont importants à caractériser dans cette population, car ils peuvent avoir un impact négatif sur les comportements diurnes. Par ailleurs, ils entrainent souvent des difficultés au sein de la famille. La prise en charge doit avant tout prendre en compte le contexte environnemental afin d’améliorer les habitudes et l’hygiène du sommeil. Des questionnaires ainsi que des agendas de sommeil ont été remplis par des parents afin de démontrer l’importance d’une évaluation et d’une prise en compte des troubles du sommeil chez les enfants souffrant d’autisme en consultation pédopsychiatrique.

La conservation de la biodiversité est devenue un challenge social, politique et économique au niveau mondial. Etant donné que certaines régions du monde sont fortement soumises à l’anthropisation et à ses impacts, il est indispensable de modifier notre perception et notre réflexion en ce qui concerne la conservation de la biodiversité et la restauration écologique. Ce chapitre explore les possibilités existantes et les adapte pour associer la conservation des espèces végétales d’intérêt avec la phytoremédiation des sols pollués. Cette nouvelle stratégie semble encourageante pour conserver le lien entre la société et l’environnement. En utilisant la diversité végétale locale, il est possible de créer de nouvelles communautés végétales afin de réhabiliter des sols pollués par les éléments traces métalliques. Le cas de la ville de Lubumbashi et de la flore de l’Arc Cuprifère Katangais en est un exemple marquant qui a été récemment testé avec succès. Cependant, d’autres études sur les métallophytes sont essentielles pour les utiliser de manière appropriée. [less ▲]

District heating networks (DHN) are generally considered as a convenient, economic and environmental-friendly way to supply heat to a large amount of buildings. Some modelling methods are required to consider the dynamic behaviour of district heating networks to design them correctly, spare the investment costs and limit the heat losses related to the use of a too high operating temperatures. For the same reasons, the DHN control or retrofit of installations also requires the assessment of the DHN dynamic behaviour. To achieve this, the heat transport in DHN, which is one of the key issues in the behaviour of a whole centralized heating system, has to be correctly modelled. Previous work evidenced current limitations of one dimensional finite volume method to model heat transport in pipes and proposed an alternative method considering the thermal losses and the inertia of the pipes. The present contribution intends to experimentally validate this model on a test rig available at the Thermodynamics laboratory of the University of Liège (ULg, Belgium) and on an existing district heating network. For both experimental facilities, the current model shows good agreement between the experimental data and the simulation results for a large range of water velocities. Moreover, it is shown that the thermal inertia of the pipe has a significant influence on the outlet pipe temperature profile. [less ▲]

This contribution focuses on modifying the composition and surface characteristics of powder metallurgy titanium substrates to improve their wear resistance and to reduce the surface Younǵs modulus, while maintaining the corrosion resistance and biocompatibility. The modification consists of Mo and TiN coatings produced by colloidal techniques which are deposited by electrophoretic deposition (EPD) or spraying onto green or sintered titanium substrates. The final surface structures are formed during a heat treatment, during which diffusion and consolidation of the layers take place. The surfaces are characterised by XRD, SEM, and micro-indentation; showing diffusion areas of between 40 and 85 microns with clear microstructural changes as well as higher hardness values. [less ▲]

In order to understand the dynamic of the (sub)urbanisation and so, to quantify the anthropogenic effects of the rapid growth of tropical cities, it is crucial to find and apply valuable methods. In this contribution, the transferability of the Rüdisser et al. (2012) «Distance to Nature» hemeroby assessment method to the landscape surrounding the city of Lubumbashi (DRC) is evaluated. That methodology has the advantage of taking structural connectivity into account by computing the distance to natural habitats. As it had never been applied to an African city before, some adjustments (fitting of the local land uses types into the hemeroby levels designed to Austria) and amendments (suppression of the final classification into hemeroby level simplification) are proposed. Moreover, an analysis of the decanal (2002-2013) hemeroby dynamics is presented. Results suggest that the Distance to Nature methodology is transferable but requires good field knowledge to define reference habitats and identify them in the Landsat classified images. There was a dramatic decrease of the «natural» and «near-natural» levels in the study extent during the studied period. In addition, 32% of the land underwent anthropisation increase, mostly around cities and following a ribbon development. [less ▲]

Despite the common conception of the dorsal premotor cortex (PMd) as a single brain region, its diverse connectivity profiles and behavioral heterogeneity argue for a differentiated organization of the PMd. A previous study revealed that the right PMd is characterized by a rostro-caudal and a ventro-dorsal distinction dividing it into five subregions: rostral, central, caudal, ventral and dorsal. The present study assessed whether a similar organization is present in the left hemisphere, by capitalizing on a multimodal data-driven approach combining connectivity-based parcellation (CBP) based on meta-analytic modeling, resting- state functional connectivity, and probabilistic diffusion tractography. The resulting PMd modules were then characterized based on multimodal functional connectivity and a quantitative analysis of associated behavioral functions. Analyzing the clusters consistent across all modalities revealed an organization of the left PMd that mirrored its right counterpart to a large degree. Again, caudal, central and rostral modules reflected a cognitive- motor gradient and a premotor eye-field was found in the ventral part of the left PMd. In addition, a distinct module linked to abstract cognitive functions was observed in the rostro- ventral left PMd across all CBP modalities, implying greater differentiation of higher cognitive functions for the left than the right PMd.

The aim of this chapter is to investigate diaphasic variation in the texts written by the Deir el-Medina scribe Amennakhte son of Ipuy in New Kingdom Egypt (ca. 1150 BCE) by analysing the graphemic and linguistic features of the registers used by this individual when writing texts belonging to different genres. The registers are conceived here as selections operating within the scribal repertoire. At an empirical level, this study is intended as a first step towards a comprehensive description of the types of linguistic variation found within the written production of the Deir el-Medina community in New Kingdom Egypt (ca. 1500–1050 BCE). At a more methodological level, as a case study testing the applicability of some historical sociolinguistic methods in the field of Ancient Egyptian, which could ultimately result in refining our approach to its diachrony.

L'immense espace géographique qui va de la Terre de Feu au Sud du Texas et des côtes du Chili aux Petites Antilles fut le théâtre d'une histoire marquée par d’incessants mouvements migratoires qui débutèrent au XVIe siècle avec la colonisation. La diversité et l’ampleur de ces flux d'hommes de toutes races, de toutes provenances et de toutes croyances ont été à l'origine de phénomènes d'acculturation complexes et variés. Les musiques indigènes, européennes et africaines ont été réinterprétées, recréées pour aboutir à des formes inédites variant selon les régions ou le degré d’influence de chacune des sources. Ce vocabulaire est destiné à donner un aperçu de cette immense richesse et à éclairer le public francophone sur ces traditions musicales qui, pour certaines, se sont largement diffusées. [less ▲]

This paper presents a novel equivalent, which is suitable for simulation of inertial and primary frequency control effects. In the model reduction procedure, dynamic power injectors are used to replace the external system and to mimic its dynamic behavior. The parameters of the equivalents are tuned with a simple approach presented in this paper. The effectiveness of the proposed method is demonstrated on a modified version of the ENTSO-E Dynamic Study Model. The results show that the system frequency response of the unreduced system is retained and a speedup of the simulations of around 4.0 is achieved. [less ▲]

This article stems from the discrepancy between the lack of attention paid to industrial land policy by academics and the predominant thought among elected representatives and development agencies, i.e. that industrial land policy plays a key role in the creation of growth and new jobs. The article begins with a reflection on the literature, which stresses the need to develop knowledge on industrial land policies. To help fill this research gap, we have developed an exploratory piece of research on the theme of their spatial and economic effectiveness, on the basis of statistical analyses dedicated to seven countries. As regards spatial effectiveness, the results underline significant national differentials in terms of land consumption on the one hand, while highlighting the economic sprawl that affects France and Belgium on the other hand. As regards economic effectiveness, our results show that the impact of the development of economic estates on growth depends largely on regional contexts. In particular, the “intermediate regions” in western Germany stand out as belonging to a specific context where land policies seem particularly effective from an economic standpoint. By contrast, the economic effectiveness of industrial land policies requires readjustments in most “predominantly rural regions, close to a city”. [less ▲]

Aphids are frequently engaged in mutualistic associations with endosymbionts. Symbionts are bacterial or fungal microorganisms that can be obligate or facultative to aphids. Research showed facultative (or secondary) symbionts have numerous effects on their host aphids such as resistance to heat shock, parasitoids and fungus etc., which may consequently promote a co-evolution between symbionts and hosts. However, this symbiotic relation may be affected by several factors, such as the ability of symbionts to spread from aphids to others within and across populations, and the cost of infections for hosts. Moreover, aphid-symbionts interactions may be affected by aphid living environment such as its host plant, the presence of natural enemies or the temperature. Here we firstly described the functions of nine facultative symbionts (Serratia symbiotica, Hamiltonella defensa, Regiella insecticola, Rickettsia, Rickettsiella, PAXS (pea aphid X-type symbiont), Spiroplasma, Wolbachia and Arsenophonus) studied in aphids one by one, and discussed the associations between these symbionts and aphids, plants and environment. We aim to have a better knowledge of the roles the facultative symbionts play in aphid biology, ecology and evolution, which we believe can provide new inspirations for aphid control. [less ▲]
