Dans cet article, je suggère que la théorie reinachienne du jugement peut être vue comme une contribution à une théorie générale de l’intentionnalité cognitive et de ses modes. À cette fin, je focaliserai mon attention sur certaines divergences significatives entre Reinach et Brentano. Après quelques réflexions introductives (§§ 1-2), j’examinerai plus exactement les questions suivantes : quels sont les motifs théoriques qui ont conduit Reinach à s’écarter de la théorie brentanienne du jugement (§§ 3-4) ? Et que retenir de ses analyses aujourd’hui (§§ 5-6) ? [less ▲]

A stylistic analysis of Corazón de Kaláshnikov (2009) by Alejandro Páez Varela highlights that the novel is extremely elliptic: the focalization of the characters is external, the causal relations are implicit and the style is very much paratactic. This seems to correspond to an ethical choice for not participating in the sensationalist representations of the violence in Ciudad Juárez, an option Páez Varela shares with the Bolaño of 2666, specifically the part about the femicides. At the same time, Corazón de Kaláshnikov seems to be typical of a certain style practiced in the north of Mexico, tense and sober, and related to a peculiar geographic and climatic environment.

The submarine part of the North Anatolian Fault (NAF) in the Marmara Sea is a significant hazard for the city of Istanbul (Turkey). The use of paleoseismological data to provide an accurate seismic risk assessment for the area is constrained by the fact that the NAF system is submarine near Istanbul; thus a history of paleoearthquakes can be inferred only by using sediment cores. Here a record of turbidites was obtained in two cores and used to reconstruct the earthquake history along a main branch of the NAF, the Cinarcik Segment. Kullenberg core Klg04 (4 m long) was collected during Marmarascarps mission from a berm north of the fault and a second core (Klg03, 3.5 m long) was positioned in the Cinarcik Basin, 3 km south of the fault. Sedimentary sequences in the two cores were correlated using variations in Ca/Ti ratio, which reflect the local aquatic productivity compared with more terrigenous input. The turbidites between the two cores were then classified to distinguish the synchronous ones from the other ones. Radionuclide measurements suggest that the most recent turbidite recorded in both cores was triggered by the M=7.3 1894 earthquake. We conclude that the turbidites are earthquake-generated, based on: 1) their distinctive sedimentological and geochemical signatures, previously described and applied in the Marmara Sea; 2) the correlation of turbidites between cores at berm and basin sites; 3) the match of the most recent turbidites with a 19th century historical earthquake; and 4) the elimination of others processes. Because of its specific geomorphological location, core Klg04 likely records only mass wasting events related to the rupture on the Cinarcik Segment. To date older turbidites, we used 14C and paleomagnetic data to build an OxCal age model with a local reservoir correction (ΔR) of 400±50 yr. The Cinarcik Segment is found to have ruptured in AD1894, AD1509, sometime in the 14th century, AD989, AD740 and in the 5th century and have a mean recurrence interval of rupture between 243 and 396 years. Following the age model obtained we finally used the earthquake record history of the Cinarcik Segment to infer the rupture history of adjacent segments of the North Anatolian Fault during six earthquake cycles over the past 1500 years.

Thanks to the precision of Kepler observations, [3] were able to measure the linewidth and amplitude of individual modes (including mixed modes) in several sub- giant power spectra. We perform a forward modelling of a Kepler subgiant based on sur- face properties and observed frequencies. Non-adiabatic computations including a time- dependent treatment of convection give the lifetimes of radial and non-radial modes. Next, combining the lifetimes and inertias with a stochastic excitation model gives the ampli- tudes of the modes. We can now directly compare theoretical and observed linewidths and amplitudes of mixed-modes to obtain new constraints on our theoretical models. [less ▲]

During the past 2 decades, many interventions were proven effective in the management of postmenopausal osteoporosis. The objective of an anti-osteoporosis treatment is to reduce fracture rates, ideally at all skeletal sites (i.e. spine, hip, and other non-spine). The armamentarium against osteoporosis includes anti-resorptive agents (i.e. bisphosphonates, selective estrogen receptor modulators and denosumab), bone-forming agents (i.e. peptides from the parathyroid hormone family) and one agent with a dual mechanism of action (i.e. strontium ranelate). All these medications combine anti-fracture efficacy with a reasonable benefit/risk profile. However, the choice of a particular chemical entity, in one individual patient is based on the knowledge and expertise of the physician. Prioritization of drugs should be based on the individual profile of the patient, the severity of osteoporosis and the specific contraindications, warnings and precautions of use of the various available medications.

Osteoporosis affects millions of elderly patients, and anti-resorptive drugs (ARD) such as bisphosphonates (BP) represent the first-line therapy. Despite the benefits related to the use of these medications, osteonecrosis of the jaw is a significant complication in a subset of patients receiving these drugs. CASE PRESENTATION: This report documents a case of dramatic bisphosphonate-related osteonecrosis associated with periodontitis and dental implant removal in an osteoporotic patient treated with per os bisphosphonates for an uninterrupted period of 15 years. CONCLUSION: The aim of this report was to discuss the administration period of BP in the treatment of osteoporosis, the decision-making and clinical management of severe MRONJ and the indications for dental implant placement in these specific patients.

An original experimental set-up combining a FTIR microscope with a high pressure cell has been built in order to analyze in-situ the impregnation of solute into microscopic polymer samples, such as fibers or films, subjected to supercritical CO2. Thanks to this experimental set-up, key factors governing the impregnation process can be simultaneously followed such as the swelling of the polymeric matrix, the CO2 sorption, the kinetic of impregnation and the drug loading into the matrix. Moreover, the solute/polymer interactions and the speciation of the solute can be analyzed. We have monitored in situ the impregnation of aspirin and ketoprofen into PEO (Polyethylene Oxide) platelets at T=40°C and P=5; 10 and 15 MPa. The kinetic of impregnation of aspirin was quicker than the one of ketoprofen and the final drug loading was also higher in case of aspirin. Whereas the CO2 sorption and the PEO swelling remain constant when PEO is just subjected to CO2 under isobaric conditions, we noticed that both parameters can increase while the drug impregnates PEO. Coupling these results with DSC measurements, we underlined the plasticizing effect of the drug that also leads to decrease the crystallinity of PEO in situ thus favoring the sorption of CO2 molecules into the matrix and the swelling of the matrix. The plasticizing effect increases with the drug loading. Finally, the speciation of drug was investigated considering the shift of the carboxyl bands of the drugs. Both drugs were found to be mainly homogeneously dispersed into PEO. [less ▲]

Urban sprawl is transforming our landscapes and rural areas at a spectacular pace. Measuring the strength of the phenomenon and proposing dynamic ways to delineate suburban areas have been the object of much debate amongst scientists. The present article takes the view that, beyond measuring and delineating suburban areas, more efforts should be directed to qualifying the morphology of built settlements within these areas. Therefore it proposes a method based on a semi-automatic classification system of building clusters, designed to describe and interpret the phenomenon from a morphological perspective. This method is based on a combination of field surveys with numerical analyses of digital land cadastre maps. The application of this classification system to the suburban area around Liege reveals that, far from developing in a complete indifference of local conditions, contemporary suburban settlements are influenced by landscape structures inherited from the past.

Virus-like particles (VLPs) of human papillomavirus (HPV) are used as a vaccine against HPV-induced cancer, and recently we have shown that these VLPs are able to activate natural killer (NK) cells. Since NK cells collaborate with dendritic cells (DCs) to induce an immune response against viral infections and tumors, we studied the impact of this crosstalk in the context of HPV vaccination. NK cells in the presence of HPV-VLPs enhanced DC maturation as shown by an upregulation of CD86 and HLA-DR and an increased production of IL-12p70, but not of the immunosuppressive cytokine IL-10. This activation was bi-directional. Indeed, in the presence of HPV-VLPs, DCs further activated NK cells by inducing the upregulation of cell surface activation markers (CD69 and HLA-DR). The function of NK cells was also improved as shown by an increase in IFN-gamma secretion and cytotoxic activity against an HPV+ cell line. This crosstalk between NK cells and DCs needed CD40 interaction and IL-12p70 secretion, whereas NKG2D was not implicated. Our results provide insight into how VLPs interact with innate immune cells and how NK cells and DCs play a role in the immune response induced by this vaccine agent.

Solvent degradation represents one of the main operational drawbacks of the post-combustion CO2 capture process. Degradation not only induces additional costs for solvent make-up, it also impacts the process efficiency and its environmental penalty due to the emission of various degradation products. There is still a gap of knowledge about the influence of process operating conditions on degradation, making it currently impossible to predict the solvent degradation rate in CO2 capture plants. Morever, the reaction mechanisms corresponding to solvent degradation are very slow, significantly complicating its study in industrial units. In the present work, appropriate experimental equipment and analytical methods are developed for accelerating the degradation of monoethanolamine solvents (MEA). The relevance of accelerated conditions is established by comparing artificially degraded solvent samples with degraded solvent samples from industrial CO2 capture pilot plants. Two approaches are evaluated implying either discontinuous or continuous gas feed, this latest being the most representative of industrial degradation. The respective influences of the gas feed composition and the gas-liquid transfer are evidenced and quantified. Finally, the present study leads to a better understanding of solvent degradation in the CO2 capture process with MEA. More generally, it also evidences that accelerated conditions at laboratory-scale may provide relevant information for the study of slow phenomena taking place in large-scale industrial processes. Further works include the development of a kinetic model for MEA solvent degradation and the extension of this methodology to other promising solvents in order to facilitate the operation and large-scale deployment of CO2 capture.

Matériels et méthodes : l’étude porte sur un crâne déformé provenant d’Ancón au Pérou, inventorié au Muséum National d’Histoire Naturelle (MNHN) de Paris en 1889. L’étude est géographique, historique, macroscopique et tomodensitométrique. Résultats : situé sur la côte à 40 km au nord de Lima, la capitale du Pérou, le site d’Ancón est un site archéologique de la période lithique, et un lieu de sépulture depuis l’époque Chavín (1250 à 250 av. J.-Chr.). Dès l’époque Chavín, les peuples du Pérou ancien construisaient des centres cérémoniels dirigés par une élite théocratique, et déformaient le crâne des enfants dès les premiers jours de la vie, à l’aide de moyens de pression variés. La déformation du crâne d’Ancón est une déformation antéro-postérieure oblique, brachycéphale, bilobée et asymétrique, sans trépanation ni déformation dentaire associée. C’est une variante bilobée du type Huaura de déformation crânienne, qui est associé aux régions de Chancay-Ancón et Lima. L’étude tomodensitométrique des variations d’épaisseur de la voûte, avec amincissement en regard des zones de pression, a montré que la déformation était intentionnelle, et caractérisée par une pression fronto-pariéto-temporale bilatérale surtout antérieure et dégressive d’avant en arrière, associée à une pression frontale, occipitale, et sagittale médiane. En l’absence de contexte et de datation, l’ancienneté du crâne étudié ne peut pas être précisée au long d’une période de presque trois millénaires, jusqu’à la domination Inca et l’arrivée des Espagnols (1532). Le crâne pourrait appartenir à l’une ou l’autre des cultures successives du site d’Ancón : Chavín, Baňos de Boza o Miramar, Lima, Wari, et Chancay (1200 à 1470), dont les céramiques représentent la déformation bilobée. Le crâne est probablement celui d’une femme âgée de plus de 45 ans à son décès, de statut social élevé, faisant partie de l’élite magico-religieuse, politique et économique dirigeante. L’étude de l’endocrâne a permis d’observer la déformation des veines superficielles et des lobes du cerveau. Il existe des signes de parodonpathie chronique à un stade avancé. Un abcès d’origine dentaire pourrait avoir été la cause du décès. Conclusions et perspectives : en ce qui concerne la pratique des déformations crâniennes, la région d’Ancón-Chancay et de Lima paraît être remarquable à trois égards : par le grand nombre de crânes déformés, par le grand nombre de crânes bilobés, et par la proportion importante de femmes, dont on peut supposer qu’elles étaient nées de familles nobles, et destinées dès l’enfance à faire partie de l’élite théocratique. La reconstitution 3D de l’épaisseur de la voûte crânienne a permis pour la première fois à notre connaissance de caractériser ce type de déformation, et pourrait permettre de reconstituer l’appareil déformateur. Seule la reprise des exhumations programmées sur le site d’Ancón, dans le cadre d’un projet prospectif pluridisciplinaire, pourrait permettre de mieux préciser la proportion d’individus à crâne déformé, la proportion des crânes bilobés, et le sex ratio, dans chaque contexte historique et socio-culturel de ce type de déformation crânienne intentionnelle ; et, peut-être, de retrouver in situ l’appareil déformateur correspondant.
