Le miellat est une substance épaisse et collante rejetée sur les feuilles et au pied de la plante-hôte par les pucerons pour éliminer l’excédent de sucres qu’ils consomment. Des travaux récents ont montré qu’en plus des sucres et des acides aminés, le miellat contenait plusieurs souches bactériennes. L’objectif de ce travail est de déterminer si cette excrétion des pucerons possède un pouvoir éliciteur, à savoir si elle est capable de provoquer une réaction de défense de la part de la plante, ce qui la rendrait plus résistante à des attaques ultérieures. Pour ce faire, différentes étapes dans la mise en place des défenses chez la plante ont été ciblées. Une alcalinisation du milieu extracellulaire chez des cellules de tabac a été observée, essentiellement provoquée par la bactérie S. sciuri contenue dans le miellat. Les résultats permettent également de suspecter une action combinée de la bactérie avec un ou plusieurs de ses métabolites. La mise en présence de plantes entières traitées avec du miellat et du champignon pathogène B. cinerea a permis d’observer une meilleure résistance des plantes traitées. De plus, des cellules de tabac mises en présence de la bactérie S. sciuri montrent une forte mortalité, sans doute due à une réponse hypersensible. Des essais de chémiluminescence et de prélèvement de molécules volatiles ont été réalisés afin de confirmer ces observations mais n’ont donné aucun résultat significatif. Il est donc difficile de conclure, sur base de ces résultats, à l’existence d’un réel pouvoir éliciteur du miellat. Au vu des premiers résultats obtenus ici et afin de les affiner, d’autres techniques plus sensibles devraient être utilisées. [less ▲]

La neuropsychologie de l’enfant concerne un champ d’étude relativement récent et en même temps très vaste. Le but de cet ouvrage est de fournir une vue d’ensemble des connaissances scientifiques qui se sont accumulées au cours de ces dernières années, et ceci pour les principales fonctions cognitives ainsi que les populations les plus fréquemment examinées en neuropsychologie de l’enfant, en passant des troubles développementaux avec ou sans cause cérébrale et génétique clairement définie aux lésions acquises telles que le traumatisme crânien ou l’accident vasculaire cérébral. Une première série de chapitres situera les troubles cognitifs dans le cadre de la dynamique développementale qui caractérise la neuropsychologie de l’enfant, permettant de fournir une compréhension la plus complète possible des difficultés constatées. Une deuxième série de chapitres sera de nature davantage syndromique, en présentant les troubles cognitifs associés aux traumatismes crâniens, aux troubles épileptiques, aux principaux syndromes génétiques ainsi qu’à d’autres troubles développementaux tels que les troubles attentionnels avec ou sans hyperactivité et l’autisme. Dans les cas pertinents, les principaux outils d’évaluation disponibles seront développés et des pistes rééducatives discutées. [less ▲]

The aim of this paper is to investigate the effect of the change in structural weight due to optimisation experiments on life cycle cost and earning elements using the life cycle cost/earning model, which was developed for structure optimisation. The relation between structural variables and relevant cost/earning elements are explored and discussed in detail. The developed model is restricted to the relevant life cycle cost and earning elements, namely production cost, periodic maintenance cost, fuel oil cost, operational earning and dismantling earning. Therefore it is important to emphasise here that the cost/earning figure calculated through the developed methodology will not be a full life cycle cost/earning value for a subject vessel, but will be the relevant life cycle cost/earning value. As one of the main focuses of this paper is the maintenance/repair issue, the data was collected from a number of ship operators and was solely used for the purpose of regression analysis. An illustrative example for a chemical tanker is provided to show the applicability of the proposed approach. [less ▲]

In order to model the nitrate concentration of the recharge water in a spatially distributed way for the agricultural areas of the Walloon Region of Belgium, the EPIC model was first adapted to the specific soil description by modifying the reservoir sizes. It was also adapted to the regional crop production by modifying classcrop files in relation with observed data (both aerial and underground crop growth, yield) in wheat, sugar beet, and potato fields. As the vadose zone presents a depth between 1.5 and 104 m in this region, new reservoirs were added according to the geological descriptions available. Deep nitrate transfer was validated in a specific site where cropping history was known. Nitrate nitrogen after harvest in the root zone was validated for wheat within different crop rotations using the first results of a nitrate-monitoring program planned by the authorities to test the effectiveness of the mitigation measures in agriculture. This extended model was also linked to a GIS (geographical information system) using 1 km2-cells. All the required data were rasterised to allow HRU (hydrological response unit) identification within the cells. The cell’s daily water flows are weighted flows of each HRU depending on their relative area within the cell. Water balances at catchment scale allow us to validate the calculation. Taking into account the evolution of distributed land use and observed climatic data, we have built maps of fast indicators and long-term indicators. The first map represents nitrate concentration in the water leaving the root zone and the second one represents the time transfer for nitrate from 1.5 m depth to the groundwater table and nitrate concentration in recharge water. These maps constitute major tools for nitrogen management at a regional level. [less ▲]

The major limitation to the development of embryo production in cattle is the strong between-animal variability in ovulatory response to FSH-induced superovulation, mainly due to differences in ovarian activity at the time of treatment. This study aimed to establish whether anti-Mullerian hormone (AMH) was an endocrine marker of follicular populations in the cow, as in human, and a possible predictor of the ovarian response to superovulation. Anti-Mullerian hormone concentrations in plasma varied 10-fold between cows before treatment and were found to be highly correlated with the numbers of 3- to 7-mm antral follicles detected by ovarian ultrasonography before treatment (r=0.79, P<0.001) and the numbers of ovulations after treatment (r=0.64, P<0.01). Between-animal differences in AMH concentrations were found to be unchanged after a 3-mo delay (r=0.87, P<0.01), indicating that AMH endocrine levels were characteristic of each animal on a long-term period. The population of healthy 3- to 7-mm follicles was the main target of superovulatory treatments, contained the highest AMH concentrations and AMH mRNA levels compared with larger follicles, and contributed importantly to AMH endocrine levels. In conclusion, AMH was found to be a reliable endocrine marker of the population of small antral gonadotropin-responsive follicles in the cow. Moreover, AMH concentrations in the plasma of individuals were indicative of their ability to respond to superovulatory treatments. [less ▲]

This is the first report of a Si/SiGe resonant interband tunneling diodes (RITDs) on silicon substrates grown by the chemical vapor deposition process. The nominal RITD structure forms two quantum wells created by sharp delta-doping planes which provide for a resonant tunneling condition through the intrinsic spacer. The vapor phase doping technique was used to achieve abrupt degenerate doping profiles at higher substrate temperatures than previous reports using low-temperature molecular beam epitaxy, and postgrowth annealing experiments are suggestive that fewer point defects are incorporated, as a result. The as-grown RITD samples without postgrowth thermal annealing show negative differential resistance with a recorded peak-to-valley current ratio up to 1.85 with a corresponding peak current density of 0.1 kA/cm2 at room temperature [less ▲]
