The Silurian – Devonian succession have been deposited in wide sags and sub-basins in a cratonic setting, along the northwestern passive margin of the Gondwana during the opening of the proto-Tethyan ocean. During this Siluro-Devonian Period, a high subsidence occurs stacked sediment bodies and organic-rich shales were deposited in many places that respectively form important hydrocarbon reservoirs and source rocks throughout North Africa basins and Arabia (Boot et al., 1998 ; Lüning et al., 2000), which lead Algeria to hold the fourth position in terms of the estimates of technically recoverable shale oil and shale gas resources, based on major basin assessment in the world (EIA, 2013). In the prolific Illizi and Berkine basins (western Ghadames, Algeria) a basin-wide approach is needed, especially with the new “shale gas and shale oil” frontier in the upcoming years, in order to capture regional trends and re-assessment on organic-rich (‘hot’) shale unites which in smaller-scale industrial studies are overlooked. Berkine Basin covers nearly 102.000 km2. This basin has been a thick sedimentary series of 7000 m corresponding to complex reservoirs but also black shales of the basal Silurian and Frasnian respectively major and secondary source rock systems. Wireline-logs from more than 146 (Berkine – Illizi Basins) Algerian petroleum exploration wells have been studies (Djouder et al., 2012; Djouder et al., 2014), and recently 03 months extensive field study of outcrops of the Siluro-Devonian sediments was carried out at the south margin (SE, Tassili n’Ajjer) of the basin. The following analysis incorporates biostratigraphic, ichnological, sedimentological and high resolution stratigraphic data, which provides a framework evolution from offshore to deltaic deposition for the Silurian then fluvial to normal-marine depositional conditions for the Devonian. A total of 06 short-term, third-order sequences can be identified for the Silurian deposits: (i) 'Hot Shale' Oued Imihrou Formation, organic-rich shales with carbonates nodules (Si-1); (ii) above is the Atafaïtafa Formation 500 to 650 m thick with HCS, gutter casts and Cruziana Ichnofacies (Si-2, Si-3); (iii) then overlaid by coarsening-shallowing-upward units. These sequences (Si-4, Si-5 & Si-6) with Storm-wave dominated and Skolithos Ichnofacies are interpreted to reflect deltaic origin. This delta is the result of a significant sea-level drop during the Upper Silurian (Beuf et al, 1971) but also from the high sedimentation rates prograding northwards (Eschard et al., 2005). Devonian deposit also can be divided into fourth third-order sequences (Dev-1 to 4), by the same previous analysis. The base of the cycle is the Caledonian unconformity linked to a tectonic event which affected most of the Gondwanan margin at the Silurian – Devonian boundary and a major relative sea-level fall (Eschard et al., 2005). Previous sequences defined from Tassili n’Ajjer outcrops are well recognized at the basin-scale (Berkine Basin) and can be correlated in the subsurface of the Illizi – Berkine basins (Djouder et al., 2012). Finally, the full depositional cycle for the Silurian – Devonian is reached and capped by the Frasnian maximum flooding surface, with black shales across North Africa (Algeria, western Libya and southern Tunisia) and which are also developed in many parts of the world (Lüning et al., 2003).

the surface preparation of metal parts made by additive manufacturing (AM). AM is a technology of choice for manufacturing of parts with complex shapes (heat exchangers, RF supports, optical parts…) and integrated functions such as conformal cooling channels, clips, hinges, etc. This opens the door for lightweight parts which are of prime importance for space applications. The potential of the AM technologies is however impeded by the quite rough surface finish that is observed on the as-manufactured parts. It is known that such a finish is likely to impact the performance of the parts. Several post-treatment techniques can be applied to improve the surface condition of the AM parts. However, so far, the influence of the successive post-processing steps on the final properties is not well established. Therefore, a better understanding of the impact of surface characteristics on the material behaviour is needed to expand the use of AM for high performance parts. The objective of this study, supported by ESA, is to propose and evaluate various surface finishing techniques for parts made by the AM technologies, in order to check their compatibility, evaluate their properties and derive guidelines for future applications. CRM is the prime proposer of this study and is in charge of the surface treatment and characterisations. Sirris additive manufacturing facilities are used to produce the parts. Thales Alenia Space and Walopt are included into the industrial team to provide concrete application cases. The study focuses on metals. Two metals under study are presented here: AlSi10Mg and Ti6Al4V. This paper is devoted to the early results of the first steps of surface preparation, namely material removal from the surface of the produced parts in order to improve their surface properties. As a first phase, tribo-finishing (TF) is tested on prototype parts to check its capabilities. Surface and volume parameters are analyzed, namely achieved roughness, material removal rate, location of removed material. The limitations in terms of geometry and applicability are discussed as well. These first observations should serve as guidelines for further application of AM for the design of parts used in space industry. [less ▲]

Background: All-oral, interferon-free regimens that combine direct-acting antiviral drugs have significantly advanced the treatment of hepatitis C (HCV), especially for genotype 1(G1) patients. However, efficacy and safety data of interferon-free regimens in HCV genotype 4 (G4) patients are scarce. In Belgium, Sofosbuvir (SOF) and Simeprevir (SMV) treatment is available since January 2015 for G4 patients with advanced fibrosis (F3-F4 METAVIR) for 12 weeks. Methods: analysis of HCV G4 patients receiving SOF and SMV treatment in Belgium. The aim of the study was to evaluate the safety and efficacy of the treatment. Results: 73 G4 patients were enrolled in this data collection including 32 (43.8%) patients with severe fibrosis F3 and 41(56.2%) cirrhotic patients. The study population comprised 58.9% male, 77.8% treatment experienced patients. Median age was 59 [51-66] years and 5 patients were HCV/HIV co-infected. 24 patients received the treatment associated with ribavirin, 11/32 (34.37%) of patients with advanced fibrosis and 13/41 (31.71%) of cirrhotic patients. In cirrhotic patients, median MELD and Child-Pugh score were 9 [7-12.5] and 5 [5-6], 46.2% had platelet below 100.000/mm and 28.6% had albumin below 35 g/L. W4 HCV RNA was undetectable in 31.25% (15/48). 9 of the 15 patients with undetectable W4 HCV RNA received RBV. At W12, 100% (23/23) had HCV RNA below the limit of quantification, with 6/23 still detectable. All SVR12 data will be available at the time of presentation. No patient experienced serious adverse event. Conclusions: these preliminary results in difficult-to-treat G4 HCV patients show that SOF/SIM +/- RBV treatment is safe and seems promising, in line with that was observed in G1 HCV patients.

In his vision of “biopolitics” Lemke (2011) proposes to conceptualize life and politics as entities intertwined within a dynamic relationship. These technologies change the production of norms and the apparatuses (Foucault 2008) organizing the distribution of the living in the domain of utility: therefore biopolitics must be analyzed as center pieces in the transformation of politics. The developments in genomics and epigenetics support the vision of the individual body as an “information network” rather than a physical substrate. The experts (with the active support of the patients) construct models for the calculation of life in the development of policy regulation and contribute actively to frame the policy relevant issues – either at individual or at population level, on the basis of power strategies mobilizing and disseminating specific forms of knowledge which are disciplined and selective. The contribution will present the recent evolution of the apparatuses producing the technical regulation and financial norms for the use of genetic testing in the federal Belgian public health system, considering the two complementary level of the “dispositif” : - At the political level, transformation of the « Conseil supérieur de la Génétique humaine » (1973-2013) into a « Collège de médecins pour le centre de génétique humaine » and the development of new control relations between the subsidizing and control bodies and the hospitals, - At the individual level, transformation of the cooperation between medical doctors, biomedical experts and psycho-sociologists in the relationship with the patients, as they can be observed at the level of the hospital; Who has the resources (intellectual, technological or financial) to control the technology and its use ? what are the social, institutional and technological constrains? who defines and select the legitimate options ? The analysis is not so much normative than critical, giving due attention to the social context and contingent rationalities in the evolution of this peculiar political action, with the aim of opening new areas of discussions transgressing disciplinary and institutional borders which are too often considered as self evident.

The coach-athlete relationship is well documented in the literature. Based on an original research model, the study is focused on three female basketball clubs of the 1st regional division in Wallonia. Combining interviews, participant observation, focus groups, and perception questionnaires, it appears that the relational dynamics of the three sites differs considerably: ‘Back to back’, ‘Above-below’, ‘Inside’. In each case, the coach-players relationship does not seem suitable to the optimal use of the available resources, in order to reach a sport performance in agreement. Courses of actions are suggested for provoking some improvement of the situations. [less ▲]

The aquatic environment represents the final sink for many chemicals, including bactericidal agents. Among them Triclosan (TCS), with his chemical structure similar to thyroid hormones (THs), may have adverse effects on the thyroid system. The study we carried out aims to evaluate the effects of TCS exposure on development of Cyprinodon variegatus, a fish model used in ecotoxicological studies. We investigated the potential effects of TCS on C. variegatus during two key periods; embryonic development and metamorphosis. We exposed eggs and larvae to environmental relevant concentrations. We showed that TCS had no effect on reproduction parameters, such as egg fertility or survival rate of larvae. However, we highlighted the fact that hatching of exposed larvae was delayed of around 6 to 13 hours compared to control embryos. During the larval phase, measurements of THs levels were performed. We showed that TCS affected the typical ontogenic variations of the whole body thyroid hormones concentrations during metamorphosis. As THs are known to control somatic growth and development, we tested the effects of TCS exposure on morphological development. We observed no deformity or malformation, but we revealed a developmental retardation in larvae exposed to TCS, of around 18 to 32 hours. Such a developmental delay had never been highlighted in previous studies on TCS exposed fish. We hypothesize that the disruption of THs homeostasis affects the timing of the start of metamorphosis. As a consequence, exposed larvae showed an extended larval phase compared to the control group. The harmful effects of TCS on physiology and development are a major concern, as marine organisms are constantly exposed to it. Furthermore, strong connections exist between thyroid and reproductive system, which might have deleterious effects on population dynamics. [less ▲]

Over the last few years, a wide variety of background subtraction algorithms have been proposed for the detection of moving objects in videos acquired with a static camera. While much effort have been devoted to the development of robust background models, the automatic spatial selection of useful features for representing the background has been neglected. In this paper, we propose a generic and tractable feature selection method. Interesting contributions of this work are the proposal of a selection process coherent with the segmentation process and the exploitation of global foreground models in the selection strategy. Experiments conducted on the ViBe algorithm show that our feature selection technique improves the segmentation results. [less ▲]

Within the concept of "vulnerability" - considered as an inherent or innate value of the human being, from which it is necessary to start in order to build a genuine social policy- the children's vulnerability occupies a special position. Traditionally, children have been treated as objects of protection and not as subjects of rights according to an authoritarian and paternalistic perspective. Over time, a different view of this matter has developed, and it has put the child at the center of attention, considering his vulnerabilities, needs and interests. This perspective has been reflected in the legislation, in case law and doctrine, both internationally and nationally. The concept of "best interest" is the key for addressing children's vulnerability of children and developing substantive equality for them. The European Court of Human Rights in Strasbourg and the Court of Justice of the European Union in Luxembourg have defined this concept in different areas: in the field of international child abduction, immigration, asylum and family reunification, custody and parental responsibility. Although these two tribunals have grounded their arguments on different legal perspectives, both have shown and still show a trend towards convergence to common points, through a balanced consideration of rights in this area. This communication aims at examining the relevant jurisprudence of the aforementioned tribunals about the notion of "best interest" of the child. The case-law since 2011 until 2015 has been taken into account. [less ▲]
