Le LabSET accompagne annuellement une vingtaine d'enseignants dans le portage à distance de leurs propres cours conventionnels, touchant plusieurs milliers d'apprenants au total. Défenseurs des pédagogies actives, nous prônons l'idée que l'EAD n'est qu'un vecteur, un support dont on peut faire le pire comme le meilleur. L'une de nos actions, FORMADIS , assure l'accompagnement de d'EAD, une autre action accompagne des enseignants dans un curriculum diplomant, selon des principes d'isomorphisme et de transfert systématique des apprentissages au projet concret. L'article présente ces deux actions et détaille leur mise en oeuvre en soulignant les facteurs de succès et les difficultés de ces initiatives. [less ▲]

The infection of human fetal thymus organ cultures (FTOC) with coxsackievirus B4 E2 (CVB4 E2) was investigated. Both positive- and negative-strand viral RNA were detected by real-time quantitative reverse transcription-PCR (RT-PCR) in CVB4 E2-infected FTOC, which supported high yields of virus production (similar to10(6) 50% tissue culture infective doses/ml), and in flow-sorted thymocyte populations for 7 days after inoculation. Cortical CD4(+) CD8(+) thymocytes were found to be the principal targets of infection. Inoculation of human FTOC with CVB4 E2 led to a marked and progressive depletion of immature thymocytes (CD4(+) CD8(+) cells) with no enhancement of Annexin V-positive cells. CVB4 E2 replication caused significant major histocompatibility complex (MHC) class I upregulation on these cells. MHC class I upregulation was correlated with positive- and negative-strand RNA quantitative detection and the release of infectious particles. In addition, chloroquine treatment of FTOC and single-thymocyte suspensions suggested that MHC class I upregulation on thymocytes was the result of direct infection rather than caused by production of soluble factors such as alpha interferon. Thus, CVB4 E2 can infect human fetal thymocytes, which subsequently results in quantitative and qualitative abnormalities of these cells. [less ▲]

An equation solver data reconciliation software has been used to build a validated model of a waste paper deinking mill, by combining control room measurements and process design specifications. An optimal sampling protocol to validate the model by using only control room measurements has been determined by identifying, with genetic algorithm programming, the additional sampling points and corresponding sensors required to compensate for the lack of redundant measurements.

Intrauterine growth restriction (IUGR) is associated with significantly increased perinatal morbidity and mortality as well as cardiovascular disease and glucose intolerance in adult life. A number of disorders from genetic to metabolic, vascular, coagulative, autoimmune, as well as infectious, can influence fetal growth by damaging the placenta, leading to IUGR as a result of many possible fetal, placental and maternal disorders. Strict definitions of IUGR and of its severity are needed in order to eventually distinguish among different phenotypes, such as gestational age at onset, degree of growth restriction and presence of hypoxia. This report explores and reviews some of the most recent developments in both clinical and basic research on intrauterine growth restriction, by seeking mechanisms that involve genetic factors, utero-placental nutrient availability and vascular growth factors. New exciting findings on the genomic imprinting defects potentially associated with IUGR, and the placental anomalies associated with the decreased nutrient transport are summarized. Moreover, recent data on angiogenic growth factors as well as new information arising from application of gene chip technologies are discussed. (C) 2004 Elsevier Ltd. All rights reserved. [less ▲]

Bifidobacteria are normal intestinal flora in humans and animals. The genus Bifidobacterium includes 31 species of significant host specificity. Taking into account their properties, we proposed to use bifidobacteria as fecal contamination indicators. PCR-restriction fragment length polymorphism on the 16S rDNA gene was used to distinguish the different Bifidobacterium species. Sixty-four strains belonging to 13 different species were differentiated from animal or human origin using one or two restriction enzymes. Moreover, the primers used were specifics of the Bifidobacterium genus. Therefore, this method made it possible to determine both the presence of bifidobacteria in a sample and its origin of contamination. [less ▲]

The interest of functional imaging in patients in a vegetative state is twofold. First, the vegetative state continues to represent a major clinical and ethical problem, in terms of diagnosis, prognosis, treatment, everyday management and end-of-life decisions. Second, it offers a lesional approach to the study of human consciousness and adds to the international research effort on identifying the neural correlate of consciousness. Cerebral metabolism has been shown to be massively reduced in the vegetative state. However, recovery of consciousness from vegetative state seems not always associated with substantial changes in global metabolism. Recent PET data indicate that some vegetative patients are unconscious not just because of a global loss of neuronal function, but due to an altered activity in a critical fronto-parietal cortical network and to abolished functional connections within this network and with non-specific thalamic nuclei. Recovery of consciousness was shown to be paralleled by a restoration of this cortico-thalamo-cortical interaction. Despite the metabolic impairment, external stimulation still induces neuronal activation as shown by both auditory and noxious stimuli. However, this activation is limited to primary cortices and dissociated from higher-order associative cortices, thought to be necessary for conscious perception. [less ▲]

Polyamide 12 (PA 12) has been nanostructured by reactive blending with 20 wt% of a symmetric anhydride end-capped polystyrene-b-polyisoprene (PS-b-PIP-anh) The liposome-like nanovesicles which are originally formed in the polyamide matrix (PA 12) are converted into cucumber-like core-shell nanoobjects upon increasing the volume fraction of PS by addi-j tion of homo PS of a molecular weight lower than the PS block. The key effect of the molecular weight of homoPS with respect to the PS bloc,k has been emphasized. The same nanoobjects can be prepared by direct blending of PA12 with 20 wt% of an asymmetric reactive PS-b-PIP-anh diblock with the same molecular weight and a higher PS content compared to the symmetric diblock. The interesting point is that the thickness of the rubbery envelope of the core-shell nanoobjects changes with the method used for their preparation at constant PA12/ PS/PIP composition, as result of a change in the molecular weight of the shell forming block.

The momentum transfer dependence of the slopes of the spin-non-flip and spin-flip amplitudes is analyzed. It is shown that the long tail of the hadronic potential in impact parameter space leads, for hadron-hadron interactions, to a larger value of the slope for the reduced spin-flip amplitude than for the spin-non-flip amplitude. It is also shown that the preliminary measurement of A(N) obtained by the E950 Collaboration confirms such behavior of the hadron spin-flip amplitude. [less ▲]

It is shown, by means of computer simulations of the behaviour of a real structure, that it is safe to design a building with the assumption of pinned joints, even when they show a semi-rigid behaviour. This result is however limited to the cases where the joints show a high ductility, i.e. a capacity of large deformation before the rupture of either the bolts or the welds. Only in few, probably unrealistic cases, this assumption will lead to unsafe results, the lack of safety being however very small, amounting only to a few percent. (C) 2003 Elsevier Ltd.

Les données présentées dans cet article confirment de manière assez forte celles de la littérature. Les performances des sujets dysphasiques (EDP) francophones étudiés sont, d'une part, inférieures à celles d'enfants contrôles appariés sur la base de l'âge chronologique (EDL) et, d'autre part, inférieures en production par rapport à la compréhension. Les aspects morphologiques du langage posent des difficultés particulières aux EDP. Les erreurs effectuées par les EDP sont différentes de celles des enfants EDL. Le profil des EDP est tout à fait particulier et ne se superpose que sommairement à celui des EDL. De ce point de vue, nous pouvons parler de déviance. [less ▲]
