Tuiliers et potiers de la région toulousaine à la fin du Moyen Age.
Authors: Marandet Marie-Claude
Published: August 2013

According to the tile-maker's statutes of Toulouse and deeds relating to them authenticated by notariés (from 1300 to 1450) we could note the pegging out and the way of appropriation of a few tueries and the rules of manufacture.

The inventory ofa tile-maker's property gave us some informations about his working stock and his products. Other inventories after a death let us corne to the conclusion that earthenware was less used than pewter and wooden dishes. It only represents 3,9 % ofthings used for cooking or table service and it seems to be used for cooking or keeping in stock. It seems to be less used in médiéval houses than it's supposed from excavating of dwellings.
Le Garissou : villa et atelier de potiers médiévaux sur le territoire de Béziers (Hérault)
Authors: Lécuyer Nolween
Published: August 2013

The medieval villa at Le Garissou, mentioned even before the end of theXth century, is built on a hillside, 5 km North East of Béziers (Hérault). Although the housing area remains yet unexplored, a programmed salvage excavation has made possible the study of a great part of the outbuildings of the villa : they consist more particularly, of two large areas for cereals reserves, comprising about a hundred silos alongside outlying buidings. This first phase of occupation, of a relatively long duration, ended probably in the course of the XIIth century, as the whole of the structures present the characteristics of a sudden and prolonged abondonment. The place was again occupied and fitted up as apotter's and tiler's workshop : this second phase in fact shows a possible recuperation of the ancient buildings and the building of numerous ovens. Four of them dated between 1 185 and 1260 by archeomagneticanalysis, havebeen investigated, and provided a great quantity of burning rejects : grey ceramics and tiles. The excavation of the villa at Le Garissou now represents a remarkable reference for the knowledge ot the exploitation of the territory around Béziers, and of the medieval ceramics in the Languedoc.
Typologie, structure et implantation du trou de boulin dans son rapport à l'échafaudage médiéval
Authors: Reveyron Nicolas
Published: August 2013

Lorsqu'on étudie un monument médiéval, les échafaudages montés lors de sa construction apparaissent en négatif, sous forme de traces soit dans le sol : les trous ménagés pour les perches verticales, dénommées les échasses, soit dans les parements : les trous de boulin. Ces derniers se révèlent une source d'informations exceptionnelle sur la construction : structure et évolution des échafaudages, organisation du travail sur le bâti, tranches des travaux... Mais ils témoignent aussi, avec loquacité, de la culture technique d'une région ou d'une époque donnée. Faciles à repérer du sol, ils offrent un apport considérable à l'étude du monument lui-même, pour l'établissement de sa chronologie, par exemple ; par là, cette archéologie d'élévation rejoint l'histoire de l'art. Les recherches menées actuellement dans le sud-est de la France nous ont conduit à établir des normes pratiques (définition de structures, d'un vocabulaire spécifique...) qui simplifient l'étude depuis le sol et facilitent l'interprétation de l'organisation de ces traces à partir de schémas généraux attestés. Le but du présent article est de faire connaître ces résultats.
Remarques sur les techniques de construction de second art roman, à propos de Saint-André-de-Souvignargues (Gard)
Authors: Bessac Jean-Claude , Pécourt Jacques
Published: August 2013

L'église Saint-André de Souvignargues (Gard), édifiée durant le second âge roman, offre un état d'écorché architectural tout à fait exceptionnel pour la connaissance des techniques et des chantiers de construction de cette période. Le rôle majeur des ressources géologiques locales est d'abord mis en évidence. Ensuite, l'analyse de cette construction révèle clairement les tâtonnements médiévaux pour la mise au point de l'appareil alterné, de la voûte en cul de four et, d'une manière plus générale, pour le traitement de la coupe des pierres appliquée aux ensembles cylindriques à joints rayonnants. L'étude des tracés, des ornements sculptés et de la mise en œuvre vue par des professionnels de la pierre, ouvre ici des perspectives inédites sur l'organisation de ces chantiers ruraux encore mal connus. Beaucoup de ces pratiques résultent d'emprunts aux monuments antiques de la région, il en est de même pour la stylistique mais le caractère propre de l'interprétation médiévale demeure prépondérant. La "restauration" en cours, saura-t-elle respecter un tel monument ? Un important problème d'éthique se pose ici.
La faïence à Lyon du XIVe siècle au XVIe siècle : l’apport des fouilles récentes
Authors: Horry Alban
Published: August 2013

Les fouilles réalisées préalablement aux projets d’urbanisme au centre de Lyon ont permis l’analyse de nombreux lots de céramiques médiévales et modernes issus de contextes d’habitats et de dépotoirs. Elle a mis en évidence la présence de faïences originaires du bassin méditerranéen dès le XIVe siècle, auxquelles viennent s’ajouter dès le début du XVIe siècle des productions locales dues aux potiers italiens installés dans la ville. L’analyse archéologique de cette dernière apporte de nouveaux éléments à un répertoire connu uniquement au travers de pièces de musée. La diversité du vaisselier découvert permet d’effectuer quelques observations sur les échanges de Lyon vers l’Italie et l’Espagne, mais également, grâce aux porcelaines chinoises avec l’Extrême-Orient.

Authors: Codou Yann
Published: August 2013

Ce travail présente un essai de synthèse sur les relations qui s’établissent entre les lieux de culte et l’habitat dans l’espace rural provençal, sur une assez longue durée, de l’Antiquité tardive au XIIe siècle. Cette approche se fonde sur les données des sources écrites et de l’archéologie. Malgré la pauvreté de la documentation pour certaines périodes, approchables qu’à partir d’éclairages très ponctuels, il souligne le rôle structurant qu’assume l’église dans le monde rural et tente de nuancer la vision d’une Provence médiévale dominée par le fait castral où l’église se trouverait dans une position subordonnée.

Published: August 2013

The aim of the study was to analyze the clinical efficacy and safety of olfactory ensheathing cell (OEC) transplantation for treating patients with chronic, complete spinal cord injury (SCI). Six patients with six chronic complete spinal cord injuries were recruited and treated with autologous OEC transplantation and followed for 24 months. The scores from before and after transplantation were analyzed. This was a self-control experiment. There was significant amelioration in the scores of the standard neurological classification of spinal cord injury made by the America Spinal Cord Injury Association (ASIA) and the International Association of Neurorestoratology–Spinal Cord Injury Functional Rating Scale (IANR-SCIFRS) following OEC transplantation with 24 months of follow-up. No clinical complications were observed. OEC transplantation would appear to be clinically safe and may promote the neurofunctional recovery of SCI based on data from six patients. This manuscript is published as part of the International Association of Neurorestoratology (IANR) supplement issue of Cell Transplantation.

Authors: Forneris Catherine , Gartlehner Gerald , Jonas Daniel , Lohr Kathleen
Published: August 2013

The prevalence of traumatic events in both civilian and military populations and the emotional, financial, physical, and psychosocial burdens of PTSD are high. We conducted two rigorous, protocol-based systematic reviews of the published literature assessing the benefits and harms of psychological and pharmacological interventions to prevent or treat symptoms of post-traumatic stress disorder (PTSD) in adults exposed to trauma. We did not find reliable evidence supporting efficacy for most interventions to prevent PTSD. Evidence does support the effectiveness of several psychological and pharmacological interventions to treat patients with PTSD. Although some psychological interventions produced significant decreases in traumatic stress symptoms and related psychopathology, limitations in the study methods precluded definitive guidelines for preventing PTSD in those exposed to trauma. Lack of definitive evidence on interventions to prevent PTSD in adults makes clinical and policy decision making challenging. Several psychological and pharmacological interventions can reduce symptoms of PTSD in adults, but what treatment to select for individual patients remains uncertain. Practical considerations such as access to care may dictate many clinical choices. Numerous interventions warrant additional investigation, especially in comparative trials. Subgroups require more attention to clarify which interventions are efficacious for different patient populations, and research methods must be strengthened.

Authors: Tian Shi
Published: August 2013

The perfect building form coefficient (I call it “C”) as I mean, if we stand still (I mean thatwe still need rectangle space), is the quotient equal to the cylinder volume of a building divided by thebuilding’s surface. So if we regard the building envelope material is same, the best form is a cylinderform from the point of the ecological view. According to the Chinese architectural regulation Codefor fire protection design of tall building GB50045-95 (Version 2005), the maximum unit area withone unit exit in a tall residence is approximately 1256 m2 with a circle contour. As we make 3formulas: maximum C = πr2h / (2πr2 + 2πrh) = r/4 = h/4 , we can include that the residence maximumheight according to the perfect building form coefficient is 20 m, the residence form will be a cylinderand the cylinder’s radius is 20 m. But as a tall residence which is taller than 24m according to theChinese fire-protection regulation clauses, the building’s form can be a cluster of several cylindervolumes and each height is 20 m.

Authors: Li Zhi Hua , Su Xiao Zu
Published: August 2013

Fourteen concrete beams reinforced with 500MPa longitudinal steel bars, of which 6 with skin reinforcement and 8 without skin reinforcement, were tested under two-point symmetrical concentrated static loading to investigate their flexural behavior. The results indicate that the flexural behavior and deflection mode of test beams with skin reinforcement are basically consistent with those of test beams without skin reinforcement. The use of skin reinforcement can significantly reduce average crack spacing and short-time maximum crack width. And the use of skin reinforcement can also slightly increase the short-time stiffness. Under the serviceability limit state, mid-span deflections are in good agreement with the calculated values according to formula in GB50010-2010. However most of calculated average crack spacing and short-time maximum crack width are larger than measured values. According to the test results, the normal formula of crack width should be revised.

Much sustainable urban architecture in China is closely related to traditional Chinese inhabitation wisdom, which, as a collection of ancient wisdom, has accumulated for thousands of years. The wisdom, according to which the ancient Chinese constructed their living space in harmony with nature, could continue to be a reliable reference in modern urban construction projects. Moderate development, interconnectedness, and the cyclical patterns of nature are the core concepts of the wisdom. The knowledge and application of such wisdom could help in the construction of more modern, convenient, and environment-friendly cities. The modernization of urban areas should not lose sight of traditional architechual characteristics.

Published: August 2013

Simulation analyses of RC short columns are conducted under oblique horizontal seismic action monotonically using ABAQUS software. Concrete damaged plasticity model is used for concrete. Ideal elastic-plastic model is taken for steels. The results show that when the axial compression ratio was relatively low, the capacity of the columns increased with the increasing of load angle, because of the effect of tensile bars. For the relatively high axial compression ratio, the bearing capacity decreased with the increasing of angle, because of the effect of concrete in compression area.

Abstract. In the field of magnetic anomaly detection(MAD) under ocean, oceanic waves produce magnetic noise which cannot be ignored. An AR model is used to describe the noise at first. Then the MAD model is built basing on the magnetic dipole model. Finally, a method for decreasing the noise in MAD basing on wavelet denoising is proposed. According to simulation, the way of wavelet denosing has obvious effect on decreasing the noise and increasing SNR.

The grit chambers with rotational flow find wide range of application for the treatment of sandstone wastewater in hydropower stations. Aiming at the high-turbidity solid-liquid two-phase problem of a complex flow pattern, an Eulerian-Eulerian two-phase model was built, which can describe the collision term between particles in sandstone wastewater. By using CFD technology, the velocity distribution of flow at the blade position was analyzed and the different effects caused by blade numbers to the particle removal efficiency were discussed. The results show that the removal efficiency of grit chamber with rotational flow increased gradually at first and then decreased slightly. Then the number of blade is four, the optimum removal efficiency can be reached, which provided theoretical and referential basis for engineering design and operation.
