Bovine Leukemia virus (BLV) is the natural etiological agent of a lymphoproliferative disease in cattle. BLV can also be transmitted experimentally to a related ruminant species, sheep, in which the pathogenesis is more acute. Although both susceptible species develop a strong anti-viral immune response, the virus persists indefinitely throughout life, apparently at a transcriptionally silent stage, at least in a proportion of infected cells. Soon after infection, these humoral and cytotoxic activities very efficiently abolish the viral replicative cycle, permitting only mitotic expansion of provirus-carrying cells. Short term cultures of these infected cells initially indicated that viral expression protects against spontaneous apoptosis, suggesting that leukemia is a process of accumulation of long-lived cells. This conclusion was recently reconsidered following in vivo dynamic studies based on perfusions of nucleoside (bromodeoxyuridine) or fluorescent protein markers (CFSE). In sheep, the turnover rate of infected cells is increased, suggesting that a permanent clearance process is exerted by the immune system. Lymphocyte trafficking from and to the secondary lymphoid organs is a key component in the maintenance of cell homeostasis. The net outcome of the immune selective pressure is that only cells in which the virus is transcriptionally silenced survive and accumulate, ultimately leading to lymphocytosis. Activation of viral and/or cellular expression in this silent reservoir with deacetylase inhibitors causes the collapse of the proviral loads. In other words, modulation of viral expression appears to be curative in lymphocytic sheep, an approach that might also be efficient in patients infected with the related Human T-lymphotropic virus type 1. In summary, a dynamic interplay between BLV and the host immune response modulates a complex equilibrium between (i) viral expression driving (or) favoring proliferation and (ii) viral silencing preventing apoptosis. As conclusion, we propose a hypothetical model unifying all these mechanisms. [less ▲]

The aim of our study was to detect the possible uncertainties arising from tumor movements in the daily routine treatment planning, in extreme breathing conditions. Ten patients with lung cancer were enrolled into the study. According to tumor location, five patients had peripheral and five had central tumor. After the normal planning CT scan, two more scans were made with the same CT parameters in maximal exhalation and in maximal inhalation. For planning, the normal breathing scans were used with the fusion of the maximal inhalation and maximal exhalation scans. After the fusion in all breathing phases the gross tumor volumes were contoured (GTV1, GTV2, GTV3). Around the GTV1 (normal breathing phase GTV) 3 planning target volumes (PTV) were generated with the margin of 0.5 cm, 1.5 cm and 2.5 cm (PTV1, PTV2, PTV3). Individual plans were generated to all PTVs. All GTV volumes were registered. In all cases volume deviations were registered in different breathing phases (min: 1.5%, max: 35.6%). For GTV coverage comparison the coverage index (CI) was used. In case of extreme breathing conditions, using 0.5 cm margin was sufficient to reach good coverage for central tumors. For peripheral tumors 1.5 cm margin had to be used for the acceptable coverage (CI: 0.85-1.00). In our study, extreme breathing conditions were analyzed. According to our results, CT scans used in the daily routine do not exactly represent the tumor midposition and the true tumor volume. Due to breathing synchronous tumor movements, 0.5 cm margin must be used for planning in central location. In peripheral tumors wider margin should be used. [less ▲]

En Mai 2007, un recensement hydro-agricole du bassin du Kou a été organisé par le projet et l’AEDE, et effectué par les agents de la Direction Provinciale de l’Agriculture, de l’Hydraulique et des Ressources Halieutiques. Les compétences en appui-conseil sur le terrain de la DPAHRH-Houet ainsi que la confiance dont profitent ses encadreurs dans le milieu agricole étaient indispensables pour le bon déroulement des enquêtes. L’AEDE et le projet ont assumé les besoins en formation et en matériel au niveau de la DPAHRH. Le traitement des enquêtes a été fait par le projet, les résultats et la base de données résultante ont été restitués au niveau de l’administration. Pour les différentes zones agricoles du bassin du Kou, les données suivantes ont été recensées par exploitant : données d’identification & coordonnées (GPS) ; données de cultures : superficie, calendrier, ... ; points d’exhaure : prise en rivière, puisard, ... ; caractéristiques du moyen d’exhaure ; calendrier d’irrigation ; caractéristiques du puisard & coordonnées GPS. Plus de 1.200 exploitants et groupements ont été identifiés dans les 11 différentes zones agricoles. Une base de données a été élaborée à partir de ces enquêtes. Les cartes suivantes ont été établies : occupations agricoles du bassin du Kou ; utilisation des eaux de surface vs. eaux souterraines ; moyens d’exhaure ; efficiences en irrigation ; positionnement par rapport aux berges. Les superficies potentielles irrigables sont déjà atteintes dans certaines régions, mais l’expansion est loin d’être freinée. Le grand enjeu pour le développement de l’irrigation se situe dans la gestion de la ressource en eau. La sensibilisation des agriculteurs sur les bonnes pratiques de l’irrigation permettrait de limiter les pertes lors de l’application de l’eau sur les parcelles et de réduire les inégalités d’accès à la ressource qui existent entre les utilisateurs situés en amont et en aval du cours d’eau.

In this paper we use annual data on 92 French electricity distribution units (2003-2005) to estimate a benchmarking model that includes a quality of service indicator (number of interruptions). Our methodology involves the estimation of input distance functions using stochastic frontier analysis (SFA) and data envelopment analysis (DEA) techniques. The empirical results indicate that the inclusion of the quality variable has no significant effect upon mean technical efficiency scores, and the mean shadow price of one interruption is approximately ten Euros. The analysis in this paper is the first preliminary step in a larger project which is investigating the feasibility of including quality measures into benchmarking models that are often used by regulatory authorities [less ▲]

The paper deals with a new finite element scheme for non-destructive eddy-current testing (ECT) problems involving multiply connected test pieces and differential probes. It concerns a perturbation technique applied to the magnetodynamic h - phi formulation. The unperturbed field (in the absence of the flaw) is conventionally computed in the complete domain. The source of the perturbation problem is then determined by the projection of the unperturbed field in a relatively small region around the defect, the optimum size of which depends on the working frequency. The discretisation of this reduced domain is well adapted to the size of the defect and chosen independently of the dimensions of the excitation probe and the specimen under study. At a discrete level, the voltage change is efficiently computed by integration only over the defect and a layer of elements in the reduced domain that touches the defect's boundary. The accuracy of the proposed perturbation model is illustrated by comparison of the results obtained for different dimensions of the reduced domain with those achieved in the conventional way. The considered test case involves a differential probe scanning the outer surface of a metal tube for the detection of through-wall cracks. [less ▲]

Purpose - This paper seeks to develop a sub-domain perturbation technique to efficiently calculate strong skin and proximity effects in conductors within frequency and time domain finite element (FE) analyses. Design/methodology/approach - A reference eddy current FE problem is first solved by considering perfect conductors. This is done via appropriate boundary conditions (BCs) on the conductors. Next the solution of the reference problem gives the source for eddy current FE perturbation sub-problems in each conductor then considered with a finite conductivity. Each of these problems requires an appropriate volume mesh of the associated conductor and its surrounding region. Findings - The skin and proximity effects in both active and passive conductors can be accurately determined in a wide frequency range, allowing for precise losses calculations in inductors as well as in external conducting pieces. Originality/value - The developed method allows one to accurately determine the current density distributions and ensuing losses in conductors of any shape, not only in the frequency domain but also in the time domain. Therefore, it extends the domain of validity and applicability of impedance-type BC techniques. It also offers an original way to uncouple FE regions that allows the solution process to be lightened, as well as efficient parameterized analyses on the signal form and the conductor characteristics.
