Contribution à l’histoire de la diffusion des œuvres de Léonard de Vinci dans les anciens Pays-Bas à la Renaissance, cet article analyse quelques œuvres flamandes du XVIe siècle qui présentent des citations à la "Cène" de Santa Maria delle Grazie, à savoir l’une des miniatures des "Heures de Hennessy", le polyptyque de Joos van Cleve, qui autrefois rehaussait l’autel de la chapelle Sainte-Anne de l’église Santa Maria della Pace à Gênes, et qui, aujourd’hui, est conservé au Musée du Louvre et les versions de la "Cène" de Pieter Coeck van Aelst. D’une part, nous montrons ce qui, dans cette grandiose peinture murale, a retenu l’attention des Flamands, d’autre part, nous nous interrogeons sur les intermédiaires qui ont permis aux artistes actifs dans le nord de l’Europe de découvrir le chef-d’œuvre milanais.

The aim of this work is to design intra-daily recourse strategies which may be used by operators to decide in real-time the modifications to bring to planned generation schedules of a set of units in order to respond to deviations from the forecasted operating scenario. Our aim is to design strategies that are interpretable by human operators, that comply with real-time constraints and that cover the major disturbances that may appear during the next day. To this end we propose a new framework using supervised learning to infer such recourse strategies from simulations of the system under a sample of conditions representing possible deviations from the forecast. This framework is validated on a realistic generation system of medium size. [less ▲]

Shearography is a growing optical technique in the field of non-destructive testing (NDT). Hololab developed an out of plane, in line and almost common path interferometer based on polarization states separation using a coated prism for digital phase-shifting shearography. This setup is efficient but does not allow varying the shearing direction, that is an important parameter for defects detection and quantification. To overcome this disadvantage, the coated prism is substituted by a Savart plate device that allows scanning several shearing directions by rotating the device around the light propagation axis. Many advantages of the prism substitution are discussed. The behaviour of the Savart plate as a shearing device is experimentally analyzed to optimize its integration within the interferometer. Recorded phasemaps in NDT for different shearing directions are presented. [less ▲]

We introduce a new algorithm to define a stable Lagrange multiplier space to impose stiff interface conditions within the context of the eXtended Finite Element Method. In contrast to earlier approaches, we do not work with an interior penalty formulation as, e.g., for Nitsche techniques, but impose the constraints weakly in terms of Lagrange multipliers. The new algorithm allows a local construction of the Lagrange multiplier space while improving the accuracy of the computed fields. The originality of this approach with regard to former approaches lies in the use of the trace of primary shape functions defined on the domain, and a simplified procedure to define the mesh on the interface. Moreover, the newly constructed Lagrange multiplier space satisfies, in contrast to the naive approach, a uniform inf-sup condition. [less ▲]

Our study focused on an analysis of secondary schools which were renowned for placing a real emphasis on physical education, sport and/or active lifestyles. The originality of this research lies in the fact that the study represents a comparison of schools from three different cultures in Europe. Our purpose was to determine whether the students were aware of the role their secondary school played in promoting an active lifestyle and influencing their physical activity levels. The findings should provide useful feedback to practitioners in terms of both their current and future practice. [less ▲]

Holocene floodplain sediments are an important environmental archive, that can be accesed for reconstructing the past landscape dynamics either qualitatively (e.g. palynology) and quantitatively (e.g. sediment budgeting). In this study Holocene alluvial sediment deposition in two contrasting Belgian catchments was quantified and dated: the Lienne (148 km²) in the Ardennes massif and the Dijle (750 km2) in the loess region. These catchments experienced a comparable Holocene climatic variation, but differ in topography and geology with highest relief energy in the Lienne catchment. Land use history also differs with high land use intensities in the Dijle catchment since Roman times, but at least since the Middle Ages there were also large deforestations in the Lienne catchment. Detailed cumulative Holocene sediment deposition was assessed for each catchment using more then 1000 hand augerings. Detailed radiocarbon dating of fluvial deposits was performed in the Dijle catchment, while iron slag was used as a tracer for sediments deposited after 1350 AD in the Lienne catchment. Results show that sediment deposition is much larger in the Dijle catchment (~4.5 Mg ha-1 catchment area) then in the Lienne catchment (~0.2 Mg ha-1 catchment area). Dating results from the Dijle catchment show an increase of sediment deposition in the late Holocene, first starting in the colluvial valleys and later on prograding towards the main valleys. Variations in sedimentation rates can clearly be related to anthropogenous land use pressure, and the majority of the sediments found in colluvial and alluvial valleys were deposited in the last 4000 years, and in many cases even in the last 1000 years. Variations in sediment deposition within the catchment can partially be explained by differences in river valley physical settings (mainly valley slope), while in other cases hill slope sediment delivery (upstream erosion, connectivity between hill slopes and the river system) is the explaining factor. In the Lienne catchment, between 80 and 100% of the sediments present in the main valley were deposited before 1350AD, thus before the main period of forest clearance. On the other hand, about 50% of the Holocene sediment present in a main tributary was deposited after 1537 (local start of iron industry). This difference with the main valley can be explained by a difference in physical settings of the river (valley slope, stream power). These results show that the physical settings of river valleys determine how sensible the river systems are to catchment disturbances. Floodplain deposition is determined by an interplay of hill slope sediment delivery (hill slope erosion and connectivity) and physical settings of the valley itself (valley slope, discharge). As a result, quantification of floodplain deposition alone, cannot be used as a measure for historic soil erosion within a catchment or to determine intensity of human impact on the catchment.

In recent years, the mechanical study of the brain has become a major topic in the field of biomechanics. A global biomechanical model of the brain could find applications in neurosurgery and haptic device design. It would also be useful for car makers, who could then evaluate the possible trauma due to impact. Such a model requires the design of suitable constitutive laws for the different tissues that compose the brain (i.e. for white and for gray matters, among others). Numerous constitutive equations have already been proposed, based on linear elasticity, hyperelasticity, viscoelasticity and poroelasticity. Regarding the strong strain-rate dependence of the brain’s mechanical behaviour, we decided to describe the brain as a viscoelastic medium. The design of the constitutive law was based on the Caputo fractional derivation operator. By definition, it is a suitable tool for modeling hereditary materials. Indeed, unlike integer order derivatives, fractional (or real order) operators are non-local, which means they take the whole history of the function into account when computing the derivative at current time t. The model was calibrated using experimental data on simple compression tests performed by Miller and Chinzei. A simulated annealing algorithm was used to ensure that the global optimum was found. The fractional calculus-based model shows a significant improvement compared to existing models. This model fits the experimental curves almost perfectly for natural strains up to − 0.3 and for strain-rates from 0.64s − 1 to 0.64 10− 2 s − 1. [less ▲]

Vernalization is known to promote flowering in Arabidopsis thaliana by inhibiting the expression of a strong repressor: FLOWERING LOCUS C (FLC). The recent cloning of an FLC-LIKE gene in sugar beet (Beta vulgaris; BvFL1) and – here – in root chicory (Cichorium intybus; CiFL1) suggests the conservation of FLC biological function during evolution of eudicots. Hence physiological questions that remain difficult to address in Arabidopsis can be studied in other species. We investigated the correlation between CiFL1 expression and plant-age dependent responsiveness to vernalization. We also studied the effect of post-vernalization growing temperature, which can stabilize or erase the vernalized state. [less ▲]

Purpose: Print 3G is a peptidic antagonist of oncoprotein involved in breast cancer, containing 25 amino acids. The purpose of this work is to study the peptide encapsulation into PEGylated liposomes. Two formulations composed of SPC:CHOL:mPEG-750-DSPE (47:47:6) or SPC:CHOL:mPEG-2000-DSPE (47:47:6) were investigated. Methods: Unilamellar vesicles containing either mPEG750 or mPEG2000 were prepared by hydration of lipid films method. Unfortunately, a loss of Print 3G was observed during the different steps of this manufacturing technique giving rise to encapsulation efficiencies close to 0 %. Thus, the freeze-thawing method was used to enhance the amount of Print 3G encapsulated into blank liposomes prepared using the above procedure. Because many factors may influence the peptide entrapment into the vesicles (number of freeze-thawing cycles, lipid concentration, peptide concentration, mixing time and liposome composition), a design of experiment was performed (for the screening, a Plackett and Burman plan; for the optimization, a central composite design). Results: The encapsulation efficiencies obtained by the freeze-thawing method in standard conditions, varied between 17.26 ± 0.46 % (n=3) for liposomes containing mPEG750 and 26.20 ± 7.98 % (n=3) for those comprising mPEG2000. Among the different considered factors, the screening permitted to identify two factors having a positive and significant influence on the encapsulation efficiencies: the number of freeze-thawing cycles and the lipid concentration, while the presence of mPEG2000 or mPEG750 had a relatively weak effect on the encapsulation. Concerning the peptide concentration and the mixing time, no influence was revealed. For the second part of the DOE, the positive factors were optimized for the liposomes containing mPEG2000. The obtained results for liposomes containing mPEG2000 revealed a theoretical optimum at 64.75 ± 3.55 % when 11 freeze-thawing cycles were applied and for the following lipid concentrations: 36.1 mM SPC, 36.1 mM CHOL and 4mM mPEG-2000-DSPE. The experimental results showed an encapsulation efficiency of 62.68 ± 2.93 %. Conclusion: Changing the manufacturing technique permitted a significant encapsulation of Print 3G into liposomes. The DOE led to a significant improvement of encapsulation efficiencies for the liposomes containing mPEG2000. Thereafter, an optimization design for liposomes containing mPEG750 will be started.

Hypothesis / aims of study The aim of this study was to prospectively evaluate the short-term safety and efficacy of the inside-out transobturator sling procedure for treating post-radical prostatectomy (RP) stress urinary incontinence (SUI). Study design, materials and methods The sling technique uses specific instruments and a polypropylene mesh with 2 arms that are passed inside to outside through the obturator foramens, pulled for compressing the bulbar urethra upward, and tied to each other across the midline. Intra-operative urodynamic evaluation is performed to record the urethral pressure profile (UPP) and to measure the abdominal leak point pressure (ALPP) and maximal urethral pressure (MUP) before and after sling tensioning. Urodynamic measurements are repeated until tension on both arms of the mesh increases ALPP to approximately 100 cm H2O. In case of associated urethral stenosis, classic endoscopic urethrotomy is performed first. Inclusion criteria were clinically and urodynamically demonstrated SUI, positive bulbar compression test, and signed informed consent. Patients with detrusor overactivity or active urinary infection were excluded. Baseline evaluation included detailed history, physical examination with a bulbar urethra compression test, urine analysis, multichannel urodynamics, administration of self-questionnaires assessing urinary continence (questions 1 through 3 of the urinary section of the UCLA-PCI-SF questionnaire (1)) and quality of life (QoL) (Ditrovie questionnaire (2)), flexible urethrocystoscopy, and urethrocystography. The degree of incontinence was arbitrarily categorized as mild (1–2 pads/day), moderate (3–5 pads/day) or severe (>5 pads/day), as previously described (3). Follow-up evaluation at 1, 6, 12 months, and yearly thereafter included physical examination, uroflowmetry with PVR measurement, and administration of the self-questionnaires assessing urinary continence and QoL. All patients were also asked to self-evaluate their satisfaction with the treatment. Cure was defined by no pad use and improvement by a number of pads/day ≤ 2 and reduced by at least 50%. Peri- and post-operative complications were recorded. Results From April 2006 through March 2009, 95 consecutive patients who fulfilled inclusion and exclusion criteria underwent the sling procedure using the same operative protocol. As of March 2009, 58 patients who consecutively underwent the sling procedure were expected to have a minimum follow-up of 1 year. Mean age of the patients was 67.6 ± 6.5 years (range 52-79). Mean body mass index was 27.0 ± 3.6 (range 21.3 – 39.0). Of the 58 patients, 9 (16%) patients had undergone prior surgery for SUI: bulking agent injection in 5 patients, prior sling implantation in 1 patient and artificial urinary sphincter (AUS) implantation in 4 patients. A previous urethrotomy or urethral dilatation for urethral stenosis had been performed in 8 (14%) patients and 8 (14%) patients had had pelvic irradiation. Preoperatively, 14 (24%), 26 (45%), and 18 (31%) patients were using 2 (mild SUI), 3 to 5 (moderate SUI), and >5 pads/day (severe SUI), respectively. The sling procedure was performed under general and spinal anesthesia in 22 (38%) and 36 (62%) patients, respectively, and was preceded by an endoscopic urethrotomy in 5 (9%) patients. Penile prostheses were implanted concomitantly to the sling in 2 patients. Before sling tensioning, mean MUP and ALPP were 40 ± 21 cm H2O (range 5-101) and 45 ± 22 cm H2O (range 10-100). After sling tensioning, mean MUP and ALPP were 89 ± 24 cm H2O (range 44-141) and 109 ± 26 cm H2O (range 60-165). Mean increase in MUP and ALPP between post- and pre-tensioning of the sling was 49 ± 29 cm H2O (range 1-125) and 64 ± 32 cm H2O (range 20-135), respectively. Mean operative time was 65 ± 18 minutes. No intra-operative complication was noted. Seven (12%) patients required suprapubic catheterization; normal voiding resumed in all 7 patients except 1 who underwent urinary diversion for complete radiation-induced anastomotic stenosis. Mild perineal hematoma not requiring therapy was observed in 6 patients. Six-month and 1-year minimum follow-up was available on 54 (93%) and 56 (96%) of the 58 patients, respectively (Table 1). Two patients were completely lost to follow-up after the 1-month visit. At this 1-month visit, one patient was cured while the other was improved. Table 1. Postoperative pad usage Follow-up 6-month visit 1-year visit Preoperative SUI severity / Outcome Mild to moderate SUI (≤5 pads/d) Severe SUI (> 5 pads/d) Entire cohort (≥ 2 pads/d) Mild to moderate SUI (≤ 5 pads/d) Severe SUI (> 5 pads/d) Entire cohort (≥ 2 pads/d) Cure 22 (55.0%) 9 (50.0%) 31 (53.5%) 23 (57.5%) 8 (44.5%) 31 (53.5%) Improvement 13 (32.5%) 5 (27.8%) 18 (31.0%) 14 (35.0%) 6 (33.3%) 20 (34.4%) Failure 1 (2.5%) 4 (22.2%) 5 (8.6%) 1 (2.5%) 4 (22.2%) 5 (8.6%) Data not available 4 (10.0%) 0 (0.0%) 4 (6.9%) 2 (5.0%) 0 (0.0%) 2 (3.5%) Of note, at 12 months, among the 18 patients with preoperative severe incontinence, 8 (44.5%) were cured and 6 (35%) others were improved. In addition, SUI cure/improvement rates appeared to be similar at the 6 and 12 months time points. The 3 failures included one patient who had undergone post-RP radiation therapy. This man later developed a complete urethral anastomotic closure and underwent cystectomy with transileal ureterostomy 9 months after the sling procedure. The two other failed patients had a vesico-urethral anastomotic stricture before sling implantation. Both patients were implanted with an AUS after the sling procedure. After cutting the mesh arms laterally to the bulb, the AUS cuff was placed without difficulty around the bulbar urethra. The 4th failed patient had undergone previous radiation therapy and had a bulbar urethral stenosis. He is now wearing penile collectors. The 5th patient had a vesico-urethral stenosis that underwent urethrotomy just before the sling implantation. The patient has been offered the placement of an artificial urinary sphincter. Preoperative and postoperative max flow rate and postvoid residual values were not different (Table 2). Overall, QoL was substantially enhanced and 85% patients were satisfied with the procedure. Table 2. Postoperative evolution of QoL scores and voiding parameters QoL and voiding parameters Baseline (mean ± SD [range]) 6-month visit (mean ± SD [range]) 1-year visit (mean ± SD [range]) Ditrovie QoL scores (scale from 10 [best] to 50 [worst]) 32 ± 7 (17-50) 16 ± 8 (10-40) 17 ± 8 (10-42) Max flow rate (mL/sec) 20 ± 9 (6-46) 18 ± 9 (6-44) 17 ± 10 (4-51) Post void residual (mL) 17 ± 32 (0-160) 21 ± 51 (0-243) 6 ± 21 (0-87) No sling infection, urethra erosion, persistent pain or neurological complication was observed. No sling was withdrawn or cut. Interpretation of results The inside-out transobturator sling was associated with a minimal risk of intra- and post-operative complications. Postoperative SUI cure/improvement rates were found to remain stable over a 1-year period. The sling procedure appeared to be efficient at short term even in the group of patients with severe SUI before surgery. The sling procedure does not compromise concomitant penile prostheses or subsequent AUS implantation. Longer follow-up times are required to determine the long-term efficacy of this sling procedure. Concluding message The one-year results of this prospective study suggest that the inside-out transobturator sling is a safe and efficient surgical procedure at short term for the treatment of post-RP SUI.

Depuis une dizaine d’années, les eaux côtières corses sont envahies les méduses et en particulier par les Pelagia noctiluca qui présentent une nuisance pour les eaux de baignade, les installations aquacoles et hydrauliques côtières, interfèrent avec la pêche, colmatent les filets et entrent en compétition avec les poissons pour la nourriture. Leurs apparitions dans les eaux côtières sont généralement fortuites, discontinues dans les temps et dans l’espace et souvent sous forme d’essaims. Dans le cadre du programme MEDUSES, subsidié par l’Agence de l’Eau RMC, des observations visuelles directes et des comptages de Pelagia effectués depuis 2003 à partir du quai du port de STARESO montrent une augmentation graduelle de leur abondance de 2004 à 2005 suivie par une augmentation dramatique en 2006 puis une diminution significative les étés 2007 et 2008. La prolifération de Pelagia en 2006 succède à des biomasses particulièrement élevées de mésozooplancton en 2005. On peut émettre l’hypothèse que l’abondance exceptionnelle des proies planctoniques est une des causes de la prolifération. Les Pelagia vivent en essaims dont deux types sont observés en Baie de Calvi: des essaims passifs et des essaims actifs. Les essaims passifs observés dans le port de STARESO contiennent des individus généralement dégradés (perte des tentacules, du manubrium,..), voire moribonds mais qui restent urticants. Parfois réduits à la seule ombrelle, ils se déplacent peu et s’accumulent en grand nombre (parfois plus de 200 par m2), bord à bord, en essaims passifs limités aux trois premiers mètres de la surface. Ces essaims subissent une prédation active par de nombreux poissons sparidés (bogues, sars,...). Ils disparaissent en quelques heures du fait de cette prédation ou par sédimentation massive des animaux morts. Par contre, dans les eaux plus au large, nos mesures in situ de la distribution spatiale de Pelagia noctiluca montrent que durant les pics de 2006, de nombreux organismes sont présents à distance de la côte où ils forment des essaims actifs de 200 m de long et 50 m de large situés entre 10 à 60 m. Dans ces essaims actifs, on observe de 5 à 10 individus par m3. Ceux-ci sont équidistants et nagent activement avec les tentacules étendus, capturant la nourriture. Dans certains cas, des individus moribonds partiellement détruits ou à la fin de leur cycle biologique échappent des essaims actifs et dérivent passivement à la surface, sous l’action du vent et des mouvements de l’eau, vers les zones côtières. Entre ces deux types extrêmes d’essaims, divers cas intermédiaires existent. [less ▲]

Bottom friction modelling is an important step in river flows computation with 1D or 2D solvers. It is usually performed using empirical laws established for uniform flow conditions or a modern approach based on turbulence analysis. Following the definition of the flow validity field of the main friction laws proposed in the literature, an original continuous formulation has been developed. It is suited to model river flows with a wide range of properties (water depth, discharge, roughness…). The efficiency of this new formulation, theoretically established and numerically adjusted, is demonstrated through various practical applications. [less ▲]

A zone with significant irreversible processes and significant changes in flow and transport properties is expected to be formed after underground excavations. The perturbation of the excavation could lead to a significant increase of the permeability, related to diffuse and/or localized crack proliferation in the material. The main objective of the study is to model these processes at large scale in order to assess their impacts on the performance of radioactive waste geological repositories. This paper concerns more particularly the hydro-mechanical modeling of a long term dilatometer experiment performed in Mont Terri Rock Laboratory in Switzerland. The proposed model defines the permeability as a function of the aperture of the cracks that are generated during the excavation. With this model, the permeability tensor becomes anisotropic. These developments are validated with the results of the experiment. [less ▲]

MATISSE is foreseen as a mid-infrared spectro-interferometric instrument combining the beams of up to four UTs/ATs of the Very Large Telescope Interferometer (VLTI). MATISSE will measure closure phase relations and thus offer an efficient capability for image reconstruction. In addition to this, MATISSE will open 2 new observing windows at the VLTI: the L and M band in addition to the N band. Furthermore, the instrument will offer the possibility to perform simultaneous observations in separate bands. MATISSE will also provide several spectroscopic modes. In summary, MATISSE can be seen as a successor of MIDI by providing imaging capabilities in the mid-infrared domain (for a more detailed description of MATISSE see Lopez et al., these proceedings).

Mycosubtilin is a natural cyclic lipopeptide characterized by its strong antifungal activities. It has been demonstrated that the cytoplasmic membranes of the sensitive cells are the target of this antifungal lipopeptide. In spite of the fact that some properties of mycosubtilin have been highlighted, the molecular mechanism of its biological action remains partially understood. In view of this, we investigated the interactions between mycosubtilin and cytoplasmic membranes by using biomimetic systems such as lipid monolayers at the air-water interface and lipid multilayers. These interactions were examined by different methods (pressure/area isotherms, kinetic measurements of the interfacial adsorption, Brewster angle microscopy, infrared and NMR spectroscopies). We showed that mycosubtilin does not interact strongly with the C=O ester residues of phospholipids in multilayers, while it modifies the transition temperature of the alkyl chains. It was also demonstrated that these interactions depend on the phospholipid phase. Varying the lipid composition of monolayers allowed us to demonstrate an original behavior of mycosubtilin in the presence of sterol. This suggests a mycosubtilin-sterol affinity. [less ▲]

Athletic ability of endurance horses is intimately linked to muscle oxidative capacity. Microbiopsies of triceps brachii (TB) and gluteus medius (GM) were collected before and after 10 weeks of training in 7 endurance horses to assess the feasibility of studying training effect with the use of microbiopsies. Oxygen consumption of permeabilized fibers was evaluated by high resolution respirometry (HRR) with a titration protocol that defines the activity of the mitochondrial complexes. Differences among muscles before and after training as well as training effect were assessed by Wilcoxon matched pairs test (P<0.05). No complications occurred following microbiopsies in any horse. The in situ oxidative capacity of the TB and GM increased with training. No difference was found between the TB and GM when one horse was excluded from the statistical analysis. Indeed, this horse showed signs of exercise intolerance before sampling (after the training period) which were associated to a low rate of respiration in GM but not in TB. Results of this study showed that HRR may be used to follow training effect and suggest that metabolic impairment might be detected with HRR. [less ▲]

Models predicting movement of surface applied chemicals incorporate knowledge on the water velocity field and moisture content distribution. Although the influence of root water uptake on solute transport is commonly recognized as important, it has been studied sparsely. Yet, plants may take up a large part of the infiltrating water, thereby influencing the water flow pattern in the soil and concurrently solute transport processes. For this reason, experiments are required to investigate the relationship between plant root water uptake and flow field variability. The role of root water uptake on solute transport will be elucidated in two undisturbed soil columns. During three consecutive experiments, the influence of growing barley on tracer movement through a silty soil in two lysimeters will be followed. At the first stage, an inert tracer is put on the two bare lysimeters and leached with constant irrigation. As steady-state flow can be assumed, it is possible to follow the tracer movement in the column by ERT and to identify regions of preferential flow and solute transport parameters. During the second experiment, the tracer will be applied to mature barley grown in the lysimeters. Combining the information about the water content obtained with TDR with the relation between water content, soil solution salinity and bulk electrical conductivity, the soil solution salinity distribution can be derived from images of bulk electrical conductivity obtained with ERT. Root growth will be monitored using a minirhizotron. By comparing the transport parameters obtained after these two experiments, the effect of root water on the transport process can be quantified. When the columns are washed out and the barley is harvested, the third phase will be carried out under the same steady state flow conditions as in the first experiment to investigate the effect of dead roots on soil structure.

Le débouché de la zone des puits dans les galeries du karst est considéré traditionnellement comme une suite logique de la pénétration des eaux de surface vers les collecteurs souterrains. C'est pourquoi les observations se limitent généralement à de simples descriptions morphologiques. La mise en évidence de deux ensembles dynamiques distincts, l'introduction des eaux superficielles (karst d’introduction) et la collecte/concentration/restitution aux exsurgences des eaux souterraines (karst de restitution), et l’absence de connexion systématique entre karst d'introduction et karst de restitution permettent d’envisager une évolution initialement séparée, voire diachronique, de ces deux ensembles dynamiques. Afin de vérifier cette hypothèse, nous avons étudié l’impact de la trépanation de grottes dans deux réseaux karstiques d’Europe occidentale. Le premier en Normandie (France) se développe dans des craies fines où la porosité de la roche peut atteindre 10 à 15 %. Le second se situe en Basse Meuse liégeoise (Belgique) dans des calcarénites pouvant dépasser 50 % de porosité efficace. La cavité normande, mature et fossile, est largement comblée de sédiments quaternaires (loess). Elle est reconnue sur plus de 600 m, dont un collecteur de 450 m de développement. La trépanation du collecteur fossile et comblé et son fonctionnement séquentiel ont entraîné une ablation de la partie supérieure du comblement et sa substitution par la charge terrigène introduite par les épisodes d'introduction, avec une sédimentation conforme à la dynamique de l'introduction. Mais l'incidence majeure de ces épisodes est la mise en place d'une morphologie spécifique, organisée de l'amont vers l'aval : effet barrage vers l'amont du drain avec une altération profonde de l'encaissant, ouverture d'une rampe de connexion en toit avec le drain, développement d'un chenal de voûte pénétrable, ouverture d'un grand volume vide - réservoir d'équilibre, creusement d'un chenal de voûte plus petit, qui se réduit en aval au fur et à mesure de l'absorption du flux aqueux par le remplissage et les parois du collecteur. La cavité belge, reconnue sur quelques dizaines de mètres de développement, est comblée de sédiments terrigènes, sans qu’aucune liaison karstique ne soit établie avec une quelconque émergence. L'absence de continuité karstique aval interdit le creusement du chenal de voûte, mais on retrouve le comblement terrigène granoclassé, retouché par les épisodes plus récents, et en aval le développement d'une grande chambre réservoir où la porosité élevée des calcarénites encaissantes absorbe l'eau introduite. Ces deux exemples montrent très clairement que la connexion entre l'introduction des eaux et la restitution karstique n'est pas toujours assurée et surtout que le creusement des formes d'introduction peut se réaliser indépendamment du drainage de restitution. Lorsque que ce dernier est trépané alors qu'il n'est plus fonctionnel, il enregistre les effets d'une dynamique d'introduction. La recherche de ces morphologies dans les collecteurs peut alors livrer de sérieuses indications sur l'évolution du système karstique. [less ▲]

The efficiency of the composite repair system is usually evaluated through semi-destructive test: pull-off test. But some difficulties can also be induced by the eccentricity of the load application, due to incorrect placement of the test device. The paper presents the results of a research project and the impact of incorrect design on tensile strength values. According to results of laboratory experiments and modelling, it can be observed that, if there is an influence of 2o and 4o angle of inclination on pull-off bond strength, it is however not statistically significant: the decrease of pull-off strength is usually no larger than 8% for 2o [less ▲]
