Les monts d’Aubrac : approches d’un habitat médiéval montagnard
Authors: Fau Laurent
Published: August 2013

La région de l'Aubrac, située dans le sud-ouest du Massif Central, constitue un exceptionnel conservatoire patrimonial et environnemental. La découverte d'une vingtaine de sites correspondant à des mas se trouvant entre 1100 et 1300 mètres d'altitude permet d'étudier l'habitat rural des XI-XIIe siècles. Ce dernier présente des caractéristiques architecturales liées au milieu montagnard: bâtisses enterrées, entrées aménagées, habitat et lieu destiné à la stabulation contigus. Un front de colonisation lié à un phénomène de surpopulation est certainement à l'origine de ces mas. Leur abandon précoce a laissé la place à de vastes pâturages établis par l'hôpital d'Aubrac sur lesquels l'habitat temporaire lié à la production fromagère est attesté dès le XVe siècle.
Approche palynologique et dendrochronologique de la mise en place de paysage dans le Champsaur (Hautes-Alpes, France) à l’interface des dynamiques naturelles et des dynamiques sociales. Thématique, méthodologie et premiers résultats.
Authors: Court-Picon Mona
Published: August 2013

Le développement de l’élevage en milieu montagnard, qui se fait au détriment de la forêt, accompagne l’appropriation de ce milieu par les sociétés humaines dès le Néolithique. L’histoire de la forêt et du troupeau dans les Alpes du Sud présente donc un intérêt particulier pour l’étude des relations entre l’homme et un milieu contraignant. C’est pourquoi de nouvelles études multidisciplinaires et diachroniques ont été entreprises afin de préciser les grandes phases de l’histoire des sociétés et des phénomènes naturels dans le secteur du Champsaur (Hautes-Alpes, France). L’objectif est de mettre en évidence la spécificité des rythmes d’évolution du couvert végétal et des systèmes d’exploitation à l’intérieur desquels l’élevage joue un rôle essentiel. Des analyses paléoécologiques (palynologie, dendroécologie, carpologie, anthracologie) sont réalisées pour 10 sites et complètent les données sur l’évolution de l’occupation humaine. Trois sites étagés en altitude ont d’ores et déjà fait l’objet d’analyses polliniques complètes, assorties de datations radiocarbone AMS, autorisant ici une première analyse de l’adaptation des populations alpines au système montagnard en terme d’utilisation des terres. La confrontation des données paléoenvironnementales entre elles et avec les données archéologiques permettra ensuite d’analyser et de mieux comprendre les interactions Hommes-Milieux, selon différentes situations et à différentes époques.
Regarder autrement le charbon de bois archéologique : l'exemple de l'irrigation des plantations d'oliviers en France méridionale et en Catalogne (IXe-XVe siècle).
Authors: Durand Aline , Terral Jean-Frédéric
Published: August 2013

Pendant une trentaine d’années, le charbon de bois archéologique a plutôt été considéré par la communauté scientifique comme un objet strictement paléoenvironnemental, destiné à mesurer le poids de l’homme sur le milieu végétal. Les résultats anthracologiques contribuaient à écrire l’éco-histoire des sociétés rurales et à développer l’archéologie des paysages passés. Pourtant, le charbon de bois enregistre aussi des pratiques agraires et des gestes techniques. Cette forme de lecture requiert la mise en oeuvre de protocoles inédits pour faire parler l’anatomie du bois en termes d’anthropologie historique. Grâce aux progrès de l’analyse d’images, l’éco-anatomie quantitative des bois, puis des charbons de bois, a pu se développer et autoriser ce type d’approches. Leur application à du matériel anthracologique archéologique, très récente, est faite ici sur des échantillons de charbons de bois médiévaux d’olivier. Il s’agit de reconnaître pour la première fois l’existence d’une pratique, l’irrigation, en discriminant les individus à partir de signatures anatomiques référencées sur les bois et charbons de bois actuels et avec l’aide d’analyses factorielles. Cet article est une contribution méthodologique à l’histoire de l’arboriculture fruitière médiévale et change quelque peu le regard que l’on pouvait porter sur l’une des essences emblématiques de l’agriculture méditerranéenne.
Les fruits dans les traités culinaires français (XIIIe-XVe siècles).
Authors: Mane Perrine
Published: August 2013

A travers cinq traités culinaires, rédigés aussi bien à Paris que dans le sud de la France (Forez, Languedoc oriental), nous avons essayé de recenser les différents fruits présents dans les recettes médiévales, mais aussi la manière de les accommoder. Malgré les limites inhérentes à ce type de source (public aristocratique visé, copie d’un manuscrit sur l’autre, date de composition souvent inconnue, place restreinte des fruits par rapport aux viandes et aux poissons…), des constantes apparaissent: par exemple les fruits semblent peu utilisés pour leur chair, mais plutôt pour leur apport sucré et c’est essentiellement sous la forme liquide, jus, vin ou vinaigre qu’ils entrent dans les préparations culinaires, pour cuire ou délayer et équilibrer le goût des épices. Malgré ces caractères communs, des particularités régionales émergent également, comme la saveur aigre-douce des sauces méditerranéennes, obtenue grâce à l’emploi intensif du moût qui contraste avec le goût plus ou moins acide des sauces du nord de la France.
Le château de Puivert (Aude).
Authors: Mention Karelle
Published: August 2013

La croisade albigeoise a fait naître de nombreux mythes encore présents dans les châteaux dits «cathares» dont Puivert, même si les constructions visibles de nos jours ne sont pas celles qu’attaquèrent les barons de Simon de Monfort. Le site castral puivertain étire son enceinte sur un plateau rocheux qu’un fossé transforme en éperon barré. Une vaste basse-cour rectangulaire se referme sur une tour maîtresse carrée, véritable manifestation d’orgueil et de faste. Au revers de celle-ci, la courtine enserre des bâtiments ruinés, considérés à tort comme les restes du château primitif. Ce château-cour du XIVe siècle reste fidèle aux grands fondements de l’architecture philipienne. Ses principes constructifs se basent sur les exigences de la défense et le besoin de la résidence. Puivert manifeste par la profusion de son décor sculpté éminemment symbolique et l’imposante verticalité de son donjon, toute la prééminence et la richesse de son commanditaire.
Abbayes laïques et domenjadures : l’habitat aristocratique en haut Béarn
Authors: Berdoy Anne
Published: August 2013

In the context of a study of medieval aristocracy in a sector of the western Pyrenees — the mountainous

zone of the Béarn — the data collected from written sources and fieldwork allow us to better understand of the role of the nobility in a society known for the importance of the community. In fact, the aristocratic presence was not as late or superficial as it appeared until now. A first generation, represented in each village by secular abbots, was joined nearly everywhere by lords of the feudal period. Their rights, as can

be determined based on often late or incomplete documentation, was not always negligible: on the other hand, it seems that they were rapidly eliminated by the rising power of village communities.
Standard Recommendations for the Application of Chinese Clinical Cell Therapy for Neurorestoration (2012)
Authors: Hongyun Huang
Published: August 2013

Cell therapy has been shown to be a promising alternative therapy for neurorestoration, and more than 30 different types of cells have been shown to possess some capability to restore lost or damaged neurological functions. Chinese physicians have successfully applied cell therapy to many neurological diseases and damages in the clinic and contributed to establish a discipline of neurorestoratology. To standardize the clinical procedures of cell therapy as one of the strategies for treating neurological disorders, the Chinese Branch of the International Association of Neurorestoratology (IANR) and the Preparatory Committee of Chinese Association of Neurorestoratology recently completed the Standard Recommendations (2012) for the Application of Chinese Clinical Cell Therapy for Neurorestoration. We hope these recommendations will guide clinical practice in applying cell therapy for neurorestoration, which will therein offer a reference for both Chinese and other countries' governments to make relevant official regulations. This manuscript is published as part of the International Association of Neurorestoratology (IANR) supplement issue of Cell Transplantation.
Social Networks and Popular Understanding of Science and Health: Sharing Disparities
Authors: Southwell Brian
Published: August 2013

A chorus of voices is celebrating the potential of social media and other new peer-to-peer connection technologies for teaching people about science and health in the 21st century. Rather than encouraging equity in what we all know and think about scientific discoveries, household consumer tips, the latest health recommendations, or opportunities for medical services, systematic reliance on social networks to spread information may nonetheless be a recipe for inequity. An increasing body of research suggests that people are not equal in their tendency to share information with others around them. In general, people do not take advantage of the chance to share ideas with others, a paradox in our current era of apparent information abundance. But it also appears that some people are much less likely than others to share information. Some of the differences in peer-to-peer sharing represent disparity in that information sharing is constrained unjustly by factors outside of a person’s immediate control. This book explains why these information-sharing patterns persist, why they matter to society, and what, if anything, can be done to address these tendencies.

Published: August 2013

In order to solve the strength matching problem of grouted concrete and block in mortarless grouted masonry, the article adopts the ANSYS nonlinear simulation to establish different strength grade models. And the result shows that, when the strength matching relationship between the mortarless block and the concrete reaches fc/fb=1~2, the grouted concrete and block compressive strength are brought into full play without material waste. The result is close to fcu/fcb = 1.5~3.5 (gross area) from the literature[1]. It is clear that, when the compressive strength of the two is close, their joint work can exert the best effects. It fits the experimental results and provides reference to the application of mortarless grouted block.

Authors: Chang Chung Yi , Lin Hsien Te
Published: August 2013

Greenhouse gas emissions and energy controls of industrial activities have become a main focus of the Taiwanese government, and because the cost of electricity is rising rapidly nowadays, adopting energy conservation measures to achieve cost savings and sustainable operation is essential for industries. In the textile industry, the energy consumption of A/C systems is second only to that of the manufacturing equipment. This study presents the life cycle costs and payback period by replacing old A/C systems with evaporative cooling systems. Based on the analysis, this study concludes that with evaporative cooling systems using only 10% to 15% of the energy used by A/C systems, the average payback period is less than 0.25 years despite the low electricity tariff in Taiwan. This suggests that for either the short term or the long term, evaporative cooling systems are an economical measure for the textile industry.

Authors: Niu Lin
Published: August 2013

In recent years, there has been a significant increase in the number of bridges which are being instrumented and monitored on an ongoing basis. This is in part due to the introduction of bridge management systems designed to provide a high level of protection to the public and early warning if the bridge becomes unsafe. This paper investigates a novel alternative; a low-cost method consisting of the use of a vehicle to monitor the dynamic behaviour of bridges. A truss vehicle-bridge model is used to test the effectiveness of the approach in identifying the damping ratio of the bridge with the time-delay neural networks (TNNs). A simulation study has been carried out for the incomplete measurement data. It has been observed that TNNs have performed better than traditional neural networks(NN) in this application and the arithmetic of the TNNs is simple.

In this study, the impact of introducing new sewage treatment technologies as a new policy is evaluated. The purpose of this study is to construct a comprehensive dynamic optimization model on forecasts for the net load of water pollutant and economic growth of Beijing. Therefore, a comprehensive evaluation modeling was conducted using software LINGO to perform the linear optimization model, based on tow sub-models (socio-economic model and an environmental model) and one objective (Min TQP). The socio-economic model is based on input-output table and represents the relationship between socio-economic activities and water pollutant emissions. The environmental model represents the changes in the amount of water pollutants generated. Our results propose an optimal policy for helping Beijing City to achieve the goal of sustainable development.
