The aim of this study is to explore the development of children’s narratives in three different contexts that are favorable to the production of (self-)narratives: (i) at home with parent(s), (ii) at school with peers and (iii) with a researcher in psychology. 136 children aged from 3 to 13 have been recorded 50 minutes in each situation. Once transcribed, the data were morphosyntactically annotated and processed using multivariate exploratory techniques, including Correspondence Analysis, Principal Component and Classification Analysis. The results we obtained first demonstrated that contextual indicators were more significant than age in narrative production: conversations with parents were significantly more interactive whereas interactions between children turned out to be more regressive (i.e. simplified vocabulary, demonstrative pronouns). The situation with the psychologist was the one leading to the more elaborate narratives, as children seem to show greater language control with unfamiliar adults. However, age naturally impacts the linguistic complexity of narratives, both on the lexical and morphosyntactic levels. The results we obtained enabled us to observe a gradation in the complexity of textual productions, setting the roots of the future self-narratives the subjects will be able to develop later, during adolescence. Thus, the findings show different and significant aspects of the development of narratives and self-narratives in children’s speech, considering age and context. Last but not least, they also suggest the relevance of the application of text statistics methods to clinical psychology. [less ▲]

Whereas a large body of research has investigated the maturation of inhibition in relation to the prefrontal cortex, far less research has been devoted to environmental factors that could contribute to inhibition improvement. The aim of the current study was to test whether and to what extent parenting matters for inhibition development from 2 to 8 years of age. Data were collected from 421 families, with 348 mother–child dyads and 342 father–child dyads participating. Children’s inhibition capacities and parenting behaviors were assessed in a three-wave longitudinal data collection. The main analyses examined the impact of parenting on the development of children’s inhibition capacities. They were conducted using a multilevel modeling (MLM) framework. The results lead to the conclusion that both mothers and fathers contribute through their child-rearing behavior to their children’s executive functioning, even when controlling for age-related improvement (maturation) and important covariates such as gender, verbal IQ, and place of enrollment. More significant relations between children’s inhibition development and parenting were displayed for mothers than for fathers. More precisely, parenting behaviors that involve higher monitoring, lower discipline, inconsistency and negative controlling, and a positive parenting style are associated. [less ▲]

For few years, carbon nanotubes (CNTs) are added to in various materials. As CNTs have high mechanical, thermal and electrical properties, it is expected to boost by adding CNTs the performances of the matrix material. Usually carbon nanotubes are used as additive to an organic matrix and in small quantities, below 1 wt%. In this work we develop composite materials with high amount of CNT, based on a carbon nanotubes network. The main type of CNT network manufactured and tested is buckypaper obtained by filtration of CNTs dispersed in a liquid solution. Other CNT networks like 3D preformed shape and CNT arrays have been also investigated. The potential improvement brought by adding CNT network to conventional materials has been evaluated using the engineering rules established for composites. Hence, the maximal achievable material properties have been estimated. Using the previously described analysis, the potential of CNT reinforced composite for different space applications have been ranked. The mechanical (mainly for CNT fibre) and thermal driven applications seem the most promising ones, especially if specific properties are considered (due to the low density of CNTs). On the basis of this evaluation and manufacturing technologies available in our consortium, experimental efforts have been put on the optimization of the CNT network mainly for improving its thermal performances. Influence of the CNTs characteristics on the macroscopic buckypaper properties has been evaluated with CNTs of different morphology (MWNT, DWNT), length and functionalization. Several processes for manufacturing the buckypaper have been tried, using different solutions for CNTs dispersion (surfactant, water or ethanol), or applying alternative method like in-situ growth of CNTs on buckypapers. Among different CNT network post-treatment also tried, thermal treatment up to 2800°C has given the greatest improvement on the specific thermal conductivity. Eventually the CNT network is infiltrated by an organic (epoxy) or inorganic (aluminium) matrix to make the composite. 3D shape CNT network gives highly reinforced composite with 30wt% of CNTs. Even if current properties of CNT reinforced composite materials are not yet competitive with reference aerospace materials, improvement potential is large and manufacturing technologies are growing.

Long-term genetic and functional stability is a fundamental requirement for the maintenance of microorganisms and cryopreservation is the preferred method for the long-term storage of many micro-organisms, including cyanobacteria. The BCCM/ULC collection currently holds 200 cyanobacterial strains, but only 62 are cryo-preserved. The main limiting factors are the low levels of survival of some strains and the long periods required to recover from cryopreservation, and thus the inability to deliver rapidly cryopreserved strains to the user community. The devel-opment of improved cryopreservation protocols is therefore required for the future expansion and valorization of the collection. The BRAIN-be project PRESPHOTO (preservation of photosynthetic micro-algae in the BCCM collections) (www.presphoto.ulg.ac.be) aims to improve the preservation of cyanobacterial and diatoms in the BCCM/ULC and BCCM/DCG collections, respectively.

In the available literature, some techniques of reinforcement are proposed: reinforcement with the use of cables, replacement of damage elements, creation of a composite action by connecting the damage elements to a concrete slab, etc; but few of them are applicable to the Umberto 1 gallery. The one that seems to be applicable is the FRP (Fibre Reinforcement Polymer) technique. The behaviour of composite elements composed of FRP and steel members under tension seems to be known, but little information is available as far as the behaviour of such elements in compression. Following the "Iron meeting" held in Naples on June 8th, 2006, tests on stocky elements with and without FRP are planned to be performed in tension and in compression to identify the effect of FRP on such elements. In addition, tests on slender columns will be performed with and without FRP to investigate the influence of the latter on the buckling resistance. All the tests will be accompanied by coupon tests to identify the mechanical properties of the constitutive material of the tested specimens (Liège contribution to WP7). Based on the test campaign, analytical design rules founded on an elastic approach have been developed for the computation of the resistance of iron columns reinforced by FRP; these rules are detailed in the present section and reflect the contribution of the University of Liège to WP9.
