This work aimed to describe a mechanistic model for soil heterotrophic respiration, to apply it to an agricultural soil and to specify its important parameters, in order to define future research fields. A complete description of the model structure is given. It uses a daily time step and is derived from the CENTURY model. The model was found to be independent from the initial carbon pool contents and an exponential relationship was observed between the order of stabilisation of the different pools and their respective decomposition constants. Literature was scanned to provide a panel of biochemical parameter values (nitrogen, lignin, cellulose and hemicellulose contents) for wheat, sugar beet and potato crops. Large parameter ranges of values were noticed and a lack of information about sugar beet and potato crops drove our choice to work with wheat biochemical parameters later on. An exponential relationship between two parameters linked to the effect of temperature on microbial respiratory activity, respectively Tb and h, was highlighted. For a fixed value of Q10, the values of these two parameters varied in opposite ways. The sensitivity analysis was performed at both short and long terms, mainly on the basis of carbon pool contents. The results were very variable from one pool to another. In both analyses Tb and h appeared to be the most sensitive parameters while some differences between both time spans were noticed, notably because of pool stabilisation dynamics and crop residue types. In the end, the combination of sensitivity values with parameter ranges of values brought us to consider the parameters Tb, h, Nlit (% nitrogen in above-ground residues) and Lignlit (% lignin in above-ground residues) and the forcing variables MBR (root residues quantity) and Litfall (above-ground residues quantity) as the features about which further investigations would be needed. The integration of this mechanistic model into a more complete one, also taking account of autotrophic respiration and CO2 diffusion in soils, is a further goal to achieve. [less ▲]

La première partie de cet article (voir commentaire ci-dessous) porte sur la présentation et l'analyse d'un atelier de vidéo-évaluation des stages d'enseignement que nous proposons aux étudiants de l'Agrégation de l'Enseignement Secondaire Supérieur (AESS) en Langues et littératures germaniques à l'ULg. L'approche "confidentielle" de la vidéo-évaluation est une forme d'AUTOscopie qui repose sur cinq grandes étapes : 1. l'étudiant-stagiaire (E-S) est filmé pendant une leçon qu'il donne dans le cadre de ses stages ; 2. l'E-S exprime son ressenti par rapport à la leçon donnée (auto-évaluation "à chaud") puis visionne la vidéo (évaluation "à froid") ; 3. l'E-S est invité à identifier les différences entre son évaluation "à chaud" et "à froid" ; 4. le formateur complète cette auto-évaluation par son analyse de la leçon filmée ; 5. l'E-S. identifie les axes prioritaires sur lesquels il travaillera dans les stages suivants et le formateur fournit quelques pistes pour faciliter ce transfert dans la pratique. Les principaux avantages et inconvénients de cette approche de l'autoscopie sont abordés dans la conclusion provisoire de cet article. [less ▲]

Dans cette deuxième partie (voir commentaire ci-dessous), nous décrivons une approche particulière de l'HETEROscopie de la pratique enseignante. Outre le formateur, cet atelier d'évaluation assistée par la vidéo regroupe seize personnes : deux enseignants-stagiaires (E-S) qui ont accepté d'être filmés dans le cadre de leurs stages, leurs deux maîtres de stages, et douze E-S. Ces derniers sont amenés à observer, à analyser, à évaluer, sous différents angles, les leçons données par leurs deux collègues. Les deux E-S qui ont été filmés contextualisent le montage-vidéo (max. 20') de leur leçon et précisent les objectifs qu'ils poursuivaient. Les douze E-S sont répartis en quatre groupes de trois. Chaque groupe reçoit la grille d'évaluation utilisée dans le cadre des stages et choisit un foyer d'évaluation spécifique. A l'intérieur des quatre groupes, chaque étudiant a la responsabilité d'un sous-foyer d'évaluation particulier. Une synthèse de l'évaluation est ensuite proposée par un rapporteur de chaque groupe. Pour la deuxième leçon, les trois groupes changent de foyer d'évaluation. Des suggestions prioritaires sont finalement formulées par le formateur, les maîtres de stages et, éventuellement, les collègues E-E. L'article se clôture en examinant l'intégration de ces deux ateliers de vidéo-évaluation (voir commentaire ci-dessous) dans la macro-structure méthodologique de la formation initiale en didactique des langues germaniques à l'ULg.

Currently, the art criticism encounters changes that come from the transformation of its objects and of its broadcast mediums in the digital age. To understand these changes and to evaluate the issues, we will examine the art criticism through the lense of olfactory art to show how this very specific art brings out the subjectivity, the perceptual habitus as well as the scientific and industrial limits of the art criticism.

Automated resource exchange and negotiation between participants of a Virtual Organization, or Peers of a Peer-to-Peer Grid, is an important feature of Grid computing because it enables scalable cooperation between entities under separate administrative control. Automated negotiation and accounting of resource consumption have been studied, and market-based resource exchange methods have been proposed. However, there currently exist few simulators of resource exchange accounting or actual Grid middlewares supporting negotiation with automated resource usage accounting between separate entities. We propose a Lightweight Bartering Grid (LBG) architecture suitable to the development of Peer-to-Peer Grids based on bartering (i.e. automated and accounted resource exchange), where Peers model their environment. We present the LBG architecture as well as a simulator and a middleware under development that both instantiate it. [less ▲]

Nowadays, in newly built housings, energy losses due to the ventilation can represent up to 50 % of the total building energy consumption. As a result, heat recovery ventilation units are widely used in order to save primary energy and different control strategies for ventilation systems are investigated. For instance, demand control ventilation sounds like a promising solution to decrease the energy impact of the ventilation system in the residential sector. An accurate building model integrating the influence of ventilation (so called thermo-aeraulic building model) is necessary in order to investigate the control and the impact of the ventilation system on a yearly basis. The aim of the present paper consists in a description of a combined multi-zone airflow network model and thermal building model implemented in the Modelica language. The thermal model is a simplified dynamic model using equivalent thermal resistance and capacity. The airflow network is based on the traditional electrical circuit analogy. The model can be used for ventilation systems design, infiltration rate calculation, inside air quality calculation, energy consumption calculation, etc. The first part of the paper details the multi-zone thermal building model. The results obtained from the model are compared to experimental in situ results collected in the typical single family house test facilities. Those experimental results have been obtained in the frame of the IEA-EBC Annex 58. The second part of the paper introduces the multi-zone airflow network building model. Obtained model results are compared with the results provided by a typical multizone airflow analysis software, for a simple three zones test case. The third part of the paper describes the coupling between both thermal and airflow models. The different numerical problems encountered are described and solutions are discussed. [less ▲]
