Objective: The aim of this study was to assess, through biological analysis, the local effects and osseointegration of dental implants incorporating surface micro/nanofeatures compared to implants of identical design without surface treatment. Background: Known to impact bone cell behavior, surface chemical and topography modifications target improved osseointegration and long-term success of dental implants. Very few studies assess the performance of implants presenting both micro-and nanofeatures in vivo on the animal models used in preclinical studies for medical device certification. Methods: Implant surfaces were characterized in terms of topography and surface chemical composition. After 4 weeks and 13 weeks of implantation in sheep femoral condyles, forty implants were evaluated through micro-computed tomography, histopathologic, and histomorphometric analyses. Results: No local adverse effects were observed around implants. Histomorphometric analyses showed significantly higher bone-to-implant contact in the coronal region of the surface treated implant at week 4 and week 13, respectively 79.3$\pm$11.2% and 86.4$\pm$6.7%, compared to the untreated implant's 68.3$\pm$8.8% and 74.8$\pm$13%. Micro-computed tomography analyses revealed that healing patterns differed between coronal and apical regions, with higher coronal boneto-implant contact at week 13. Histopathologic results showed, at week 13, bone healing around the surface treated implant with undistinguishable defect margins while the untreated implant still presented bone condensation and traces of the initial drill defect. Conclusion: Our results suggest that the surface treated implant not only shows no deleterious effects on local tissues but also promotes faster bone healing around the implant.

In Northern Tigray (Ethiopia), the combined presence in the valley bottoms of sedimentary fills several meters thick and of archaeological remains of human settlements (homes, camps) raises the question of the socio-environmental processes at the origin of these deposits and their interactions with human populations. However, in certain (national, legislative) contexts, it can be difficult to apply very advanced techniques or to perform a large number of analyses. This paper shows that a chronostratigraphic approach based on laser granulometry, loss on ignition and radiocarbon dating provides satisfactory answers to the main geoarchaeological questions. Our specific objective was to reconstruct the landscape and environmental changes in the region around the Wakarida archaeological site, based on the sedimentary deposits in the valley bottoms. These deposits are now cultivated by the inhabitants, thanks to the construction of agricultural terraces in the 20th century. Archaeological excavations unearthed an urban settlement at Wakarida which dates from the classical Aksumite (150–400/450 AD) and post-Aksumite (800/850 AD) periods, and traces of earlier archaeological occupations (pre- and proto-Aksumite periods, 800–50 BC) in the study area. These remains raise questions about the influence of societies on their environment. A method based on a combination of fieldwork, sedimentological analyses and dating was used to answer these questions. This chronostratigraphic study is partially based on the identification of chronological inversions, revealing ablation and depositional phases in the sedimentary cascades, which have to be taken into account to understand the evolution of the site. We identified several phases in the establishment of the present-day landscape around the Wakarida site. During the Northgrippian (Early Holocene), the valleys were progressively filled by low-energy alluvial and/or colluvial processes. During the Meghalayan (Middle Holocene), ablation processes alternated with depositions resulting from climatic processes and possible anthropogenic influences. From the 1st millennium BC, the impact of the population on its environment (deforestation) has resulted in chronological inversions in the deposits, particularly around the 14th and 17th centuries AD.

genre ,transition ,conjoints âgés ,soin ,identité - Abstract
Les conjoints sont de loin les principaux responsables et dispensateurs de soins aux personnes âgées avec incapacités. Pourtant, cet engagement semble ignoré tant par les professionnels que par la plupart des chercheurs qui semblent le tenir pour acquis. Cet article aborde la transition au soin et l’engagement des conjoints sous l’angle des enjeux identitaires, notamment l’identité assignée par la société, associée aux classements sociaux de conjoint et de genre, et l’identité que les conjoints âgés semblent s’attribuer. L’identité conjugale, telle que conçue par des répondants de trois générations de Québécois et les conjoints, est fondée sur un devoir de solidarité où contrat et confiance sont en jeu. Spouses are far and away the caregivers primarily responsible for looking after elderly persons suffering from disabilities. And yet both professionals and most researchers seem to overlook their commitment or to take it for granted. In this article the author will be looking at spousal transition and commitment to the role of caregiver from the angle of issues of identity, and more particularly the identity assigned by society at large, based on the social and gender classification of the spouse, and the identity that elderly spouses appear to attach to themselves. Conjugal identity, as perceived by three generations of respondents and spouses, is based on a duty of solidarity involving both a consensual contract and trust.

Les chantiers de l’histoire environnementale sont aussi nombreux que les enjeux soulevés par la crise écologique contemporaine. Gestion des risques par les sociétés passées, exploitation des ressources naturelles, mutation du regard porté sur l’environnement constituent quelques facettes d’une historiographie désormais mature et foisonnante. Les contributions réunies par le Réseau universitaire de chercheurs en histoire environnementale (RUCHE), à l’occasion de son 10e anniversaire, offrent un panorama international et pluridisciplinaire de cette révolution historiographique, en partant d’un état des lieux inédit dans quelques champs impactés par l’émergence d’une approche environnementale (telles l’histoire des mondes du travail et l’histoire maritime). La réflexion porte ensuite sur l’usage de sources et sur les méthodologies de recherche, en se fondant sur des exemples (comme les cartes) et en retraçant des expériences collectives de travail sur archives. Enfin, quelques études sur les acteurs et objets de l’histoire environnementale illustrent l’apport de l’interdisciplinarité pour interroger nos sociétés contemporaines.

FRACTURE healing ,HEALING ,TISSUE differentiation ,BONE growth ,TREATMENT programs ,PERIOSTEUM - Abstract
A lot of evidence has shown the importance of stimulating cell mechanically during bone repair. In this study, we modeled the challenging fracture healing of a large bone defect in tibial diaphysis. To fill the fracture gap, we considered the implantation of a porous osteoconductive biomaterial made of poly-lactic acid wrapped by a hydrogel membrane mimicking osteogenic properties of the periosteum. We identified the optimal loading case that best promotes the formation and differentiation into bone tissue. Our results support the idea that a patient's rehabilitation program should be adapted to reproduce optimal mechanical stimulations. [ABSTRACT FROM AUTHOR]

International audience; Nowadays, many parts of the world are cultivated on terraces. These include Eastern Tigray (Ethiopia) and Southern Tunisia, where such terraces allow rain-fed agriculture without irrigation. The terraces of these two regions, however, have the particularity of being erected not on the slopes but in the valleys, which they cross perpendicularly to form flat cultivation areas and conserve water and soil on the plots.In Eastern Tigray, pre-Aksumite, Aksumite and post-Aksumite archaeological remains have been unearthed on the high points overlooking the terraced valleys. The cultural exchanges between these populations and the Sabaean populations of South Arabia, renowned for their hydro-agricultural works, are well documented today and lead to the hypothesis that terraces were ancient. Similarly, in Tunisia, the attested existence of hydro-agricultural developments from the Roman period in the region raises questions about the age and origin of the actually visible structures. A methodology combining geoarchaeology, geohistory and ethnogeomorphology allows apprehending these issues and estimating the period of installation of water and soil protection structures in the two studied areas, in a comparative perspective.Moreover, the contemporary evolution of these structures raises the question of their sustainability. In Eastern Tigray, agricultural terraces represent the main, if not the only means of subsistence for the populations. They are now subject to erosion. In Southern Tunisia, the recent rural exodus has exposed the structures to rapid evolution: destruction of low walls, loss of agricultural land by suffosion. Southern Tunisia thus allows a prospective reflection on the future of Tigray in the light of the ongoing rural exodus and questions the factors of regressive erosion in these two areas. More broadly, these two case studies can serve as analogues for reflection on other terraced areas, at different periods and in different regions.

International audience; In northern Ethiopia, the villages of Sewne and Wolwalo form the centre of two areas surveyed by the French archaeological mission in the Eastern Tigray which revealed pre-Aksumite, Aksumite and post-Aksumite settlements. Around Wolwalo, the study zone is on the Tigray plateau, at an altitude of 2700 m. Around Sewne, the site of Wakarida and the surveyed area extend on a topographic spur at the altitude of 2400 m, forming a transition zone between the plateau and the valleys plunging towards the Danakil Depression. The relations maintained by the sites of the two regions with the central powers during pre-Aksumite, Aksumite and post-Aksmuite periods are still unclear, as well as the relationship between the two spaces (spur/plateau), and ancient agricultural practices.Geographically, it is a margin area with a shifting relationship to political centrality, which can be apprehended on various spatio-temporal scales, thanks to an interdisciplinary approach, combining archaeology, geoarchaeology, geohistory and ethnogeomorphology. Our geographical analysis relies on the concepts of centrality, marginalization and mobility and is part of a diachronic reflection, essentially based on the modern and contemporary periods.During the modern period, this space is subject to erosion caused by anthropogenic activities from the 14th century onwards but is nevertheless absent from travellers' accounts and early cartographies. Marginalised at the regional scale and away from the main itineraries, the studied space remains locally active and continues developing. Today, the Sewne spur constitutes a central margin: its marginal location makes it a contact zone, an interface area, where the distance from the centre leads to the creation of a new centre. This area becomes a porous and dynamic borderland between sedentary agricultural practices and nomadic or semi-nomadic agro-pastoral practices of the neighbouring Afar populations. These contemporary data provide analogues allowing to question past periods through a regressive approach.

Les quinze communications regroupées dans cet ouvrage confrontent les données provenant des sites archéologiques à celles tirées de chantiers spécialisés dans l’expérimentation de la construction et dans la restauration de monuments. Dans le domaine de l’archéologie du bâti, la lecture des vestiges conduit à la déconstruction mentale des élévations afin de restituer les phases d’occupation d’un bâtiment. Elle consiste aussi à distinguer les étapes de construction inhérentes à tout chantier, quels que soient les périodes et les lieux, en Orient comme en Occident. Il s’agit donc d’adopter une méthode d’analyse régressive pour renseigner les périodes anciennes à partir d’exemples récents de chantiers bien documentés. Si la notion de progrès existe à travers l’évolution de la science et des techniques modernes, le chantier médiéval de construction du château de Guédelon permet, par l’expérimentation, de retrouver des savoir-faire hérités du passé.

This study aims at suggesting a new approach to peri-implant healing models, providing a set of taxis-diffusion-reaction equations under the combined influence of mechanical and biochemical factors. Early events of osseointegration were simulated for titanium screw implants inserted into a pre-drilled trabecular bone environment, up to 12 weeks of peri-implant bone healing. Simulations showed the ability of the model to reproduce biological events occurring at the implant interface through osteogenesis. Implants with shallow healing chamber showed higher proportions of lamellar bone, enhanced by the increase of mechanical stimulation. Osteoconduction was observed through the surface treatment model and similar bone healing patterns compared to in vivo studies. [ABSTRACT FROM AUTHOR]

International audience; Bone repair in case of major defects remains a problem poorly solved by conventional techniques. Many researches are currently carried out in tissue engineering, using in vivo models on animals or in vitro on cell cultures, to understand and guide the mechanisms of bone repair and consolidation. New osteoconductive and osteoinductive biomaterials are developed to promote bone formation. Moreover, there is a lot of evidence on the importance of the mechanical stimulation of bone cells in the process of bone repair. Nevertheless, the mechanical environment proposed to cells within a porous biomaterial is difficult to estimate. And more importantly, in the follow-up of a patient treated for bone fracture, there is no precise management of mechanical stimulation during the rehabilitation phase with the setting up of an adapted program and the use of modern measuring tools. To study the influence of mechanical stimulation during rehabilitation and prior to complex in vivo experiments, the use of theoretical and numerical mechanobiological models of bone repair could be an alternative. Here tissue formation and differentiation were predicted in a porous poly-lactic acid biomaterial and a hydrogel membrane filling a large bone defect in a human tibial diaphysis. We identified optimal loading case promoting the differentiation of tissue into mature bone in the diaphysis defect. We indicated that the rehabilitation program should be adapted to reproduce this optimal mechanical stimulation. Taking advantage of the growth of the simulation means and by a greater synergy with the experimental models, the numerical modeling of the bone consolidation can constitute a complementary tool for the benefit of patients.

International audience; In southern Tunisia, agricultural land has been subject to significant anthropogenic pressures since the early 20th century, which have contributed to significant changes in land use. The region's strong demographic growth has led to socio-spatial changes (sedentarisation, the descent of mountain populations down to the foothills and the Djeffara plain, the development of agriculture in the jessour (water and soil conservation works that block the gullies dug in the loess) at the expense of the rangelands. The current landscapes of southern Tunisia, from the Matmata region to the surroundings of Tataouine, now display signs of a rural exodus that is reflected in the abandonment of the jessour. This exodus has significant landscape and environmental impacts that can be measured through the use of diachronic vertical imagery (aerial photographs, satellite images). It can be observed that from the 1950s onwards, jessour developed strongly in the ravines, in line with demographics. The rural exodus that appeared in the 1970s led to the concentration of populations in the new towns, which did not prevent water and soil conservation works from continuing to be used and maintained. While some areas, particularly in the southern part of the study area, are still seeing the appearance of new jessour, most of them are abandoned and subjected to regressive erosion due to the suffocation that rapidly destroys them.; Dans le Sud Tunisien, les terres agricoles sont soumises depuis le début du XXe siècle à d’importantes pressions anthropiques qui ont contribué à modifier largement l’occupation des sols. La forte croissance démographique de la région a entraîné des mutations socio-spatiales (sédentarisation, descente des populations montagnardes vers les piémonts et la plaine de la Djeffara, développement de l’agriculture dans les jessour (ouvrages de conservation des eaux et des sols qui barrent les ravines creusées dans les lœss) au détriment des parcours). Les paysages actuels du Sud Tunisien, de la région de Matmata aux environs de Tataouine, montrent aujourd’hui les signes d’un exode rural qui se traduit notamment par l’abandon des jessour. Cet exode a des impacts paysagers et environnementaux conséquents, qu’il est possible d’appréhender et de quantifier grâce à l’utilisation de l’imagerie verticale diachronique (photographies aériennes, images satellitaires). On observe ainsi qu’à partir des années 1950, les jessour se développent fortement dans les ravines, en lien avec la démographie. L’exode rural qui apparaît dans les années 1970 se traduit par la concentration des populations vers les villes nouvelles, qui n’empêche pas que les ouvrages de conservation des eaux et des sols continuent à être utilisés et entretenus. Si de nos jours certains secteurs, en particulier au sud de la région étudiée, voient encore l’apparition de nouveaux jessour, la plupart d’entre eux sont abandonnés et soumis à une érosion régressive due à la suffosion qui les détruit rapidement.

WORLD War I ,PHOTOGRAPHY archives ,LANDSCAPES ,HISTORICAL literacy ,REMOTE-sensing images - Abstract
During the First World War, a significant part of the fights took place in the Balkans, on a front line running along the borders of Albania, Bulgaria, Greece and North Macedonia. They left a lasting footprint on the landscapes, which remains less precisely assessed than on the Western Front. However, a century after the end of the war, traces or consequences are still perceptible. Opposing armies left behind many remnants such as fortifications or defensive works, a dense network of trenches, small railways, grounds which were heavily destroyed by artillery fire or even villages totally ruined and sometimes never reoccupied. Identifying these "polemoforms" can find its place in various approaches devoted to the landscape: knowledge of its historical evolution and of the degree of disappearance of the war footprints, characterization of their memorial value, protection of the historical legacy, identification of grounds likely to keep buried ammunition leftovers. This communication will present the contribution of French cartographic and photographic archives dating from the First World War and recent satellite images to identify the traces left by that military conflict and assess their persistence in current landscapes.

International audience; Well known in West Africa, the African Humid Period (AHP) can also be spotted in sedimentary accumulations in East Africa. The earlier deposits (7th millennium BCE), found in valleys around the axumite (1st-6th Century CE) site of Wakarida (northern Tigray, Ethiopia), seem to correspond to the wet conditions of the end of the AHP. Ages range from the 7th millennium BCE to the 17th Century CE and analyses show variations in depositional environments. Gaps in the dating in Wakarida could correspond to drier spells, identified by Dramis et al. (2003) in other Ethiopian places. At the turn of the 3rd/2nd millennium BCE, the aridification of the climate, pointed by Pietsch and Machado (2014) in Yeha, is sensible through the accumulation of silts, interbedded with gravels. This evolution towards a drier climate has consequences for the vegetation cover and the erodibility of the hillsides. At the end of the AHP, the sediment accumulations are mainly fine-grained, testifying of low competence processes. Nevertheless, coarse beds (with pebbles and gravels) show the occurrence of higher energy events and/or higher sensitivity of the drainage basins to erosive processes. Those can be attributed to climatic changes but they can also be the results of a progressive opening of the vegetation by a growing population. It is not easy to determine whether those changes are the result of climatic, anthropogenic or mixed processes. Sedimentary records dating from the pre-axumite period (800-0 BCE) could indicate the beginning of the clearing of the vegetation by population living in or around the archaeological site, even though no archaeological evidence of cultivation has been found in the excavations. Climatic and anthropogenic processes continue to combine in more recent periods, with two wetter spells leading to sedimentary accumulations in the 8th Century BCE and around the 12th-14th and 15th-17th Centuries CE. After the 17th Century, we lose track of accumulations processes and ablation seems to take place, leading to the erosional forms that we can see nowadays. At present time, the area around Wakarida seems to meet an unprecedented phase of incision and sedimentary crisis, which results in important headward erosion in the valleys’ sedimentary fillings and endangers food security in this dry and highly populated area. This chronostratigraphic work has been conducted within a five-kilometre radius study area around the archaeological site and relied on the interpretation and sampling of sixteen sections, laser granulometry and C14 dating of charcoal samples. Working at the scale of small watersheds and multiplying the number of studied sites allows to understand the functioning of the catchment on long time and to identify and integrate some controlling factors like the organisation of the basin or the connectivity between upstream and downstream parts of the valley.

Le projet consistait à analyser l’évolution des pressions engendrées par les prélèvements agricoles et les dérivations industrielles sur les écoulements naturels dans les trois bassins du site atelier depuis le XIXe siècle (Ardèche, Cèze, Gardons). Si de nombreuses études ont été menées sur les effets environnementaux des grands ouvrages, la connaissance du rôle joué par la « petite hydraulique » sur les écoulements et les milieux est encore assez lacunaire. Jusqu’à présent l’accent a surtout été mis sur les obstacles physiques opposés au transit sédimentaire et aux flux biologiques : chaussées, barrages, prises d’eau (Walter et Merritts, 2008 ; Lespez et al., 2013). Les aspects quantitatifs ont été plus rarement étudiés dans une perspective temporelle longue (Berger, 1998 ; Jacob, 2005, 2015 ; Jacob et al., 2016), alors qu’un des enjeux actuels est de cerner des niveaux de pression acceptables dans des bassins où la ressource est fortement sollicitée ou risque d’être sujette à une raréfaction consécutive aux changements climatiques. Le travail s’est appuyé sur des documents statistiques produits à la fin du XIXe siècle (1862-1899) qui décrivent les pressions industrielles et agricoles soit à l’échelle du réseau hydrographique (prises d’eau), soit à l’échelle du bassin (surfaces irriguées) et sur une base de données hydrologiques contemporaine, le Réseau Hydrographique Théorique (RHT) (Pella et al., 2012). Le traitement de ces informations dans un SIG a permis une comparaison de la pression sur les eaux de surface à la fin du XIXe avec la situation actuelle à l’échelle du sous-bassin et du tronçon ainsi qu’une simulation des effets de ces dérivations sur des débits caractéristiques. La confrontation avec des reconstructions et réanalyses hydrométéorologiques a permis de contraindre les incertitudes concernant les données hydrologiques utilisées pour cette étude. L’information historique a permis également d’orienter le diagnostic écologique basé sur les stratégies biologiques (trait) adoptées par les différentes espèces composant les communautés de macroinvertébrés benthiques de façon à déterminer si les pressions hydrauliques jouent un rôle sur ces communautés et, indirectement, sur les écosystèmes aquatiques.

International audience; In Northern Tigray (Ethiopia), contemporaneous agriculture is based on soils stored and developed on terraces, upstream of dry-stone walls crossing the thalwegs of this mountainous area. The discovery, during archaeological surveys, of aksumite and pre-aksumite settlements on the site of Wakarida and its surroundings, questions the age of such terraces landscapes. Comparing with ancient terraces from all over the world, dating from the 3rd millennium BCE, as well as with the functioning of contemporaneous structures maintaining soils and forming thick accumulations, raises the question of the age of those constructions and of their role in the sedimentary filling of the valleys. Sedimentological study and dating of deposits, consultation of iconographic and textual archives, of ancient aerial photographs and conducting of ethnogeomorphological interviews with farmers have formed the basis for first hypotheses regarding the evolutions of the landscape and the environment since the Mid-Holocene. Results tend to show that terraces are recent and develop on inherited sedimentary fillings. These ones testify from changes in the human occupation in the area, from a light footprint to a strong demographic pressure during Aksumite times, followed by an abandonment phase and very recent reoccupation.; Dans le Tigray septentrional (nord de l’Éthiopie), l’agriculture contemporaine se développe sur des sols retenus à l’amont de terrasses, murets de pierre sèche qui barrent les thalwegs de cet espace montagneux. La découverte, lors de fouilles archéologiques, d’implantations humaines axoumites et pré-axoumites sur le site de Wakarida et dans ses alentours questionne l’ancienneté de ces paysages de terrasses. La comparaison avec des ouvrages semblables, découverts lors de fouilles archéologiques dans d'autres sites à travers le monde et dont les plus anciens datent du IIIe millénaire av. n. è., mais aussi avec le fonctionnement de terrasses contemporaines retenant les sédiments et formant d’importantes accumulations, pose la question de l’âge de ces ouvrages et du rôle qu’ils jouent dans les comblements sédimentaires de vallons. L’étude sédimentologique et la datation des dépôts, la consultation d’archives iconographiques et textuelles, de photographies aériennes anciennes et la réalisation d’entretiens ethnogéomorphologiques auprès d’agriculteurs permettent l’élaboration de premières hypothèses quant aux évolutions paysagères et environnementales depuis le milieu de l’Holocène. Les résultats tendent à montrer que, dans la zone d’étude, les terrasses sont récentes et se développent sur des comblements sédimentaires hérités. Ces derniers témoignent de changements dans l’occupation humaine de la région, d’une présence légère à une forte pression démographique durant la période axoumite, suivie d’une phase d’abandon et d’une réoccupation très récente.
