Etude de la céramique médiévale (VIIe-XIIe siècles) de Saint-Gilles-le-Vieux (Aimargues, Gard)
Authors: Mercier Catherine , Barberan Sébastien 
Published: August 2013

Le site de Saint-Gilles-le-Vieux, où une villa est mentionnée au début du XIe s., se trouve dans la vallée du Vidourle, à trois km au Nord d'Aimargues (Gard). Une fouille de sauvetage, réalisée dans le cadre des travaux du T.G.V. Méditerranée, a permis d'explorer des zones vouées à l'exploitation agraire et comportant essentiellement des fossés, des fosses et des silos qui s'échelonnent entre la Protohistoire et le Moyen Age.
Pour la période comprise entre le VIIe et le XIIe s., la documentation céramique permet d'étoffer les études en cours, avec notamment l'enrichissement du corpus grâce à la présence de poteries complètes. La réalisation d'analyses au radio- carbone apporte également des confirmations de datation. La fouille de Saint-Gilles-le-Vieux constitue désormais une des références pour la connaissance des céramiques alto-médiévales languedociennes.
Paysage et mise en valeur des palus du Bordelais au Moyen Age
Authors: Lavaud Sandrine 
Published: August 2013

Malgré un intérêt nouveau des historiens depuis quelques années, les palus du Bordelais médiéval sont mal connues, car elles ont été transformées par les travaux de drainage du XVIIe siècle et, à proximité des villes, par l’urbanisation croissante. Ces lisières de terre qui bordent les cours d’eau sont considérées comme des espaces a priori hostiles et dénoncés comme tels par ceux qui les ont asséchés. Pourtant, à la fin du Moyen Âge et au début de l’Époque moderne, ces palus apparaissent attractives: en témoignent tant le morcellement foncier, les multiples usages et usagers des palus
que les obstacles à l’assèchement. Pourquoi un tel engouement pour ces zones marécageuses? Quels atouts présententelles? L’une des réponses à ces interrogations tient, en premier lieu, à la géographie et au milieu particulier des palus: ces terres alluvionnaires qui s’étirent le long de la Garonne et de la Dordogne sont souvent dépressionnaires et saturées d’humidité mais elles sont réputées pour leur fertilité et facilement accessibles par voie d’eau; de fait, elles appellent la conquête. Leur mise en valeur est précoce dans les palus suburbaines grâce à l’action conjuguée des seigneurs ecclésiastiques et des bourgeois qui y exploitent les prés et les vignes. Dans l’arrière-pays de Bordeaux, la bonification des terres basses ne devient effective qu’à la fin du Moyen Âge. Les palus constituent alors un véritable front pionnier pour le vignoble. Là s’édifient des exploitations de pointe, les bourdieux, ancêtres de nombreux châteaux viticoles du Bordelais, et véritables lieux d’innovation porteurs de modernité pour le vignoble médiéval.
Auberoche : un castrum périgourdin contemporain de l’an Mil
Authors: Laborie Y. 
Published: August 2013

In the Périgord region, the deserted castrum of Auberoche allows an archaeological approach to the genesis of the stone castle and to the material culture of the rural medieval peopling. Our investigations focussed on three essential sectors that permit us to determine the global history of the site: a terrace habitat in the lower section, a segment of the upper enceinte and the main construction by which it was commanded. Despite their limited nature, these elements revealed the principal phases of the chronotopographic evolution of this castrum of public origin, from the time of its founding by Frotaire, bishop of
Périgueux (991) to its definitive desertion at around 1450. Three stages can be defined. Around 980-990, on a spur fortified by a fosse, a large stone edifice,
rectangular, which was both defensive and residential, was erected. It shows the emergence, which we believe to be spontaneous, of the multi-functional donjon by enclosure of the aristocratic hall within a
volume increasingly militarised and vertical, under the influence of the political and social mutation
generated by the power of the chatelaine. In the second half of the 11th century, a constructed enceinte
completed the fortification of the castrum. At the same time, while subservient to the viscounts of Limoges, it federated as a contingent of milites and became the chef-lieu (administrative center) of a banal seigneury. In the early years of the 12th century, a low enceinte defined a subordinate habitat and shows the impact
of this seigneury on the peopling of this territory. At the end of its expansion of power, and just before
meeting its destiny as one of the places bitterly disputed during the Hundred Years War, the influence of castle of Auberoche extended over around 15 parishes.
Two-Dimensional Modelling and Validation of the Mass Flow in a Mixing Stirred Reactor

Published: August 2013

The present work focuses on the computational modelling of fluid flow in a mixing stirred reactor to describe the flow pattern in two-dimensional (2D) detail, which can be useful for optimizing the parameters of electroplating for the production of a uniform film on metallic particles in a stirred electrolytic cell. The results of modelling and simulation show that the electrolytic cell geometry and the presence of a solid electrode affect the streamline distribution. The most important parameter affecting the fluid flow is not just the position but also the size of the stirrer as well. It is concluded that the “high cell” with the “big stirrer” can be used for the electroplating of iron micro-and nanoparticles in the presence of the cylindrical electrode.

AbstractBackgroundRemote ischemic preconditioning (RIPC) is the application of a transient and brief ischemic stimulus to a distant site from the organ or tissue that is afterward exposed to injury ischemia, and has been found to reduce ischemia–reperfusion injury (IRI) in various animal models. RIPC appears to offer two distinct phases of endothelial IRI protection, which are presumably mediated through neuronal and humoral pathways.MethodsWe conducted a comprehensive literature review on the available published data about the potential effect of RIPC in patients undergoing IRI in one or more vital organs.ResultsOur search highlighted 24 randomized clinical trials about the effect of RIPC on variable clinical settings (abdominal aortic aneurysm repair, open heart surgery, percutaneous coronary intervention, living donor renal transplantation, coronary angiography, elective decompression surgery, carotid endarterectomy, recent stroke, or transient ischemic attack combined with intracranial carotid artery stenosis). Most of the trials focused on postoperative cardiac or renal function after RIPC with conflicting results. Preconditioning protocols, age limits, comorbidities, and concomitant drug use varied significantly across trials, and therefore no firm conclusions can be drawn using the available data. However, no severe local adverse events were observed in any patient undergoing limb or arm preconditioning.ConclusionsRIPC is a safe and well‐tolerated procedure that may constitute a potentially promising innovative treatment in atherosclerotic diseases. Large, multicenter, randomized clinical trials are required to determine an optimal protocol for the RIPC procedure, and to evaluate further the potential benefits of RIPC in human ischemic injury.

Two‐phase grouping‐based resource management for big data processing in mobile cloud computing
Authors: Park JiSu , Kim Hyongsoon , Jeong Young‐Sik , Lee Eunyoung 
Published: August 2013

SUMMARYBig data is generated from recent social network services, and distributed processing techniques have been studied to analyze it. In particular, because of the fast spread of mobile devices, a huge amount data is generated in a mobile environment. The distributed processing technologies such as MapReduce are applied to mobile devices, thanks to the improved computing power of mobile devices. However, mobile devices have several problems such as the movement problem and the utilization problem. Especially, the utilization problem and the movement problem of mobile devices cause system faults more frequently because of dynamic changes, and system faults prevent applications using mobile devices from being processed reliably. Therefore, to cope with these significant problems of mobile devices, we propose a grouping technique based on the utilization and movement rates. In our proposed scheme, mobile devices are separated into groups by cut‐off points based on entropy values. We also propose a two‐phase grouping method in order to reduce the overhead of group management. The experimental result shows that our algorithm outperforms traditional grouping techniques with maintaining stable big data processing and managing reliable resource.

Experimental and numerical study of a self‐centering prestressed concrete moment resisting frame connection with bolted web friction devices
Authors: Song Liang‐long , Guo Tong , Chen Cheng 
Published: August 2013

SUMMARYThe self‐centering prestressed concrete (SCPC) moment resisting frame (MRF) with web friction devices (WFDs) is a new type of structure that integrates advantages of post‐tensioned precast concrete MRFs and self‐centering steel MRFs. In this paper, the configuration of the connection and design guidelines are presented. To further reduce damage to the connection under cyclic loading and facilitate implementation in practice, several significant improvements are proposed and experimentally validated in this study, including the following: (i) the welded connection is replaced by the bolted connection; (ii) aluminum plates are used for friction instead of brass plates to reduce the material costs without decreasing the energy dissipation capacity; and (iii) post‐tensioned tendons at the corners of the beam are replaced by a bundle of tendons at the beam centroid in order to facilitate the field assembly. The resulting improvements of seismic performances are experimentally demonstrated by 10 cyclic tests of two full‐scale SCPC beam–column connections. Numerical simulation of the proposed connection is conducted using the Open System for Earthquake Engineering Simulation (OpenSees) to replicate the experimental results. Seismic behaviors are taken into account, such as the gap opening/closing at the beam–column interface, the self‐centering capacity, and the friction energy dissipation. Good agreement is observed between the numerical simulation and the test results. The proposed SCPC connection with bolted WFDs is demonstrated to have good performance when subjected to cyclic loading. Copyright © 2013 John Wiley & Sons, Ltd.
Morphological Analyses of Polymer Electrolyte Fuel Cell Electrodes with Nano‐Scale Computed Tomography Imaging
Authors: Litster S. , Epting W. K. , Wargo E. A. , Kalidindi S. R. , Kumbur E. C. 
Published: August 2013

AbstractWe report a three‐dimensional (3D), pore‐scale analysis of morphological and transport properties for a polymer electrolyte fuel cell (PEFC) catalyst layer. The 3D structure of the platinum/carbon/Nafion electrode was obtained using nano‐scale resolution X‐ray computed tomography (nano‐CT). The 3D nano‐CT data was analyzed according to several morphological characteristics, with particular focus on various effective pore diameters used in modeling gas diffusion in the Knudsen transition regime, which is prevalent in PEFC catalyst layers. The pore diameter metrics include those based on chord length distributions, inscribed spheres, and surface area. Those pore diameter statistics are evaluated against computational pore‐scale diffusion simulations with local gas diffusion coefficients determined from the local pore size according to the Bosanquet formulation. According to our comparison, simulations that use local pore diameters defined by inscribed spheres provide effective diffusion coefficients that are consistent with chord‐length based estimations for an effective Knudsen length scale. By evaluating transport rates in regions of varying porosity within the nano‐CT data, we identified a Bruggeman correction scaling factor for the effective diffusivity.
Prevalence of strong vertical CO2 and O2 variability in the top meters of the ocean

Published: August 2013

AbstractThe gradient in the partial pressure of carbon dioxide (pCO2) across the air‐sea boundary layer is the main driving force for the air‐sea CO2 flux. Global data bases for surface seawater pCO2 are actually based on pCO2 measurements from several meters below the sea surface, assuming a homogeneous distribution between the diffusive boundary layer and the upper top meters of the ocean. Compiling vertical profiles of pCO2, temperature, and dissolved oxygen in the upper 5–8 m of the ocean from different biogeographical areas, we detected a mean difference between the boundary layer and 5 m pCO2 of 13 ± 1 µatm. Temperature gradients accounted for only 11% of this pCO2 gradient in the top meters of the ocean; thus, pointing to a heterogeneous biological activity underneath the air‐sea boundary layer as the main factor controlling the top meters pCO2 variability. Observations of pCO2 just beneath the air‐sea boundary layer should be further investigated in order to estimate possible biases in calculating global air‐sea CO2 fluxes.
