Cet article examine la reconversion de la "Halle aux pigeons" en "Maison de l'Habitat durable" à Lille, démontrant comment la préservation du patrimoine architectural peut être harmonisée avec les impératifs de durabilité de notre époque. L'étude repose sur une méthodologie interdisciplinaire qui intègre des domaines diversifiés, pour mettre en relief les avantages et les défis inhérents à cette approche. L'idée fondamentale est que la reconversion des édifices historiques en espaces contemporains et durables représente une solution viable pour préserver le patrimoine tout en répondant aux besoins actuels. Pour atteindre cet objectif, l'étude fait appel à des méthodes de collecte de données exhaustives, notamment l'analyse documentaire et visuelle, ainsi que l'analyse qualitative, à la fois thématique et comparative. L'objectif ultime est de fournir une compréhension approfondie de cette entreprise de préservation durable du patrimoine bâti, en mettant en lumière son histoire, sa transformation, et son influence sur le tissu urbain contemporain.

Abstract: The Hôtel-Dieu in Valenciennes was excavated in 2016 by the municipal archaeological service. This excavation was a unique opportunity to record the medieval state of the hospital founded in 1430, only known beforehand through written and iconographical sources. The excavation mainly uncovered the western part of the main building. The construction analysis revealed that the sick ward and the chapel didn’t originally occupy the whole building, as the newly uncovered western part housed a semi-excavated space, taking a third of the building. Other arrangements of that same building (water tank, cave) show a will to facilitate the work of nurses by accommodating the requirements of the spiritual as well as the physical aspects of healing. The results must have been found efficient by contemporaries, as it later influenced the construction of the large building of the hospices in Beaune. Last, the excavation of two closed spaces gave various information about the material environment of the sick and their healers, as well as other aspects of healing: food, hygiene, medicine. Two glass sprinklers discovered showed the influence of the Arabic world on the equipment of the hospital in the 15th c.

ABSTRACT: The purpose of this article is to analyze the discourse of official town planning documents and those held by the urban actors to reveal the diversity and complexity of representations of the centrality of Greater Tunis. Divergent and converging representations which do not seem to be evoked in the discourses analyzed to be expressed only in the places of centrality perceived, conceived and lived in the city of Tunis; but also, to use their complex contents in order to convince the logics of oriented urban action and the ideologies of their producers as to their visions of the city in general. It is then that one might think that it is probably not the meaning of the representation of urban centrality in its producer that is the most instructive, but rather the way in which this representation is instrumentalized in the various discourses. RÉSUMÉ : L'objet de cet article s'intéresse à l'analyse des discours des documents officiels d'urbanisme et ceux tenus par les acteurs urbains pour révéler la diversité et la complexité des représentations de la centralité du Grand Tunis. Représentations divergentes et convergentes qui ne semblent pas être évoquées dans les discours analysés pour s'exprimer seulement sur les lieux de centralité perçue, conçue et vécue dans la ville de Tunis ; mais également, pour user de leurs contenus complexes afin de convaincre des logiques d'action urbaines orientées et des idéologies de leurs producteurs quant à leurs visions de la ville en générale. C'est alors qu'on pourrait penser que ce n'est probablement pas le sens de la représentation de la centralité urbaine chez son producteur qui est le plus instructif, mais plutôt la manière avec laquelle cette représentation est instrumentalisée dans les divers discours.

L´instabilité antérieure de l´épaule suite à une luxation traumatique chez l´adulte jeune est une complication fréquente. La procédure de Latarjet est la technique la plus utilisée pour traiter cette instabilité, consiste à réaliser une butée coracoïdienne au niveau du bord antérieur de la glène. Cependant, l´exposition articulaire au cours de cette technique est souvent limitée et rend le positionnement de la butée difficile. Pour évaluer l´effet de la position de la butée coracoïdienne sur la qualité du résultat fonctionnelle à court et moyen termes. Nous avons étudié chez 70 patients la position de la butée coracoïdienne sur la radiographie standard post-opératoire et le résultat fonctionnel par le score du duplay et le taux de satisfaction. L´âge moyen été de 25 ans et demi, le sexe-ratio était de neuf et le recul moyen était de 6,5 ans. L´étude radiologique a montré que la butée coracoïdienne était en position sus équatoriale ou non affleurante du rebord glénoïdien antérieur (trop interne ou saillante en intra-articulaire) dans 20% des cas. Ce groupe a présenté une baisse du score moyen de stabilité par 7,68 points, de la douleur par 10,04 points et du score global de Duplay par 13,3 points, ainsi qu´une augmentation significative du taux d´arthrose gléno-humérale. Ainsi, une butée coracoïdienne en position sus équatoriale ou non affleurante a un effet délétère sur la qualité des résultats fonctionnels de la technique de Latarjet.

INTRODUCTION: As COVID-19 pandemic is rapidly evolving, there is a whole reorganization in hospitals to concentrate more resources to face the crisis. The purpose of this study is to evaluate the impact of COVID-19 disease on urological activity in Tunisia. To assess the differences in the management of urological conditions between the private and the public field. METHODS: a survey was addressed to all certified urologists working in Tunisia in both the public and private sectors (n=194) using the national database of active urologists available and updated. We either called them or looked them up through email or social media. The form was open from March the 28th to April the 3rd. Results were obtained via spreadsheet and analysed using SPSS 23.0. RESULTS: one hundred and twenty urologists have filled in the form. Consultations at the outpatient office were restricted to urgent cases in 66% (n=79). Telemedicine was more used by urologists in private than in public field p=0,03. Urologists in private sector followed more the sterilization protocol of the hospital/clinic and used more disposable materials whenever possible p=0,011. Elective surgical activity has completely stopped in 85% of the responders (n=102). Elective surgery requiring transfusion or intensive care unit was performed in 38% (n=46) and 26% (n=31) if there was a risk of disease progression. BPH surgery was more performed as usual in private sector than in public sector p=0,012. It was the only condition managed differently between both sectors. CONCLUSION: the drop of the urological activity is essential in order to give relevant stakeholders room to act efficiently against the spread of the virus. The context of the pandemic and the hospital´s condition must be taken into consideration without compromising the patient´s outcome.

Lymphomas are a heterogeneous group of malignant tumours of the haematopoietic system characterized by an aberrant proliferation of mature lymphoid cells or their precursors and mainly represented by non-Hodgkin´s lymphomas (NHL). The aim of this paper was to report two cases of NHLs with mandibular locations by detailing their different clinical, radiological, and histopathological aspects, as well as the approach followed to diagnose these diseases and to provide patients with the appropriate therapeutic management. The first case is about a 72-year-old female patient who was diagnosed with a large B-cell lymphoma while the second one concerns a 16-year-old male patient who was diagnosed with a Burkitt´s lymphoma. These observations represent the two highly aggressive known NHLs according to the WHO classification. The mandibular locations of these diseases are rare and represent only 0.6% of all the reported cases. It is important to note that only a deep and good quality tumour biopsy can provide a diagnosis of certainty. The reference treatment is medical consisting in the introduction of chemo-immunotherapy. As oral surgeons, we have an important role in the early diagnosis of these malignancies and in the patient’s referral to specialized care in order to get the appropriate treatment.

To evaluate the efficacy of endoscopic meatotomy in the treatment of ureterocele in adults. A retrospective study of adult patients with ureterocele, treated between January 1987 and December 2014. In 47 patients, 55 intravesical ureteroceles were diagnosed and classified as 18 right, 21 left and eight bilateral (38%, 44% and 17% respectively). According to the Bruézière classification, 41 (75%) ureteroceles were type A and 14 (25%) others were type C. These ureteroceles were complicated by calculus formation in 22 cases, moderately dilated excretory pathways in 16 cases and both complications in a total of 9 cases. Four patients had a complicated ureterocele with pyelonephritis, one of which was emphysematous. The endoscopic treatment was performed in cases of complicated and/or symptomatic ureteroceles. Fifty one cases were treated by a "smiling mouth" meatotomy consisting in a transverse horizontal incision, with the treatment of any associated complication. The mean operative time was 35 minutes (10-90). The operative follow-up was uneventful in 42 patients and complications occurred in 5 patients (2 urinary retentions, 2 infectious complications and one hematuria). The mean duration of postoperative stay was 1-2 days. The mean follow-up was 15 months. Four patients developed vesicoureteral reflux and no stenosis was noted. The endoscopic incision of the ureteroceles seems today, after reviewing the results, to be a good treatment of adult ureterocele. It is a simple, minimally invasive and has a low morbidity rate.

Le traitement de la maladie de Basedow repose sur trois thérapies: le traitement médical par les antithyroïdiens de synthèse, la chirurgie et l'irathérapie. L'objectif de notre étude était d'étudier la place et l'efficacité du traitement à l'iode radioactif dans le traitement de la maladie de Basedow. Une étude rétrospective portant sur 54 patients suivis pour une maladie de Basedow et traités par iode 131. On a mené en une étude descriptive des aspects épidémiologiques, cliniques, para cliniques et thérapeutiques et du le taux de rémission à court et à moyen terme. Le sex-ratio était de 0,45. L'âge moyen est de 38,33 ± 12,7 ans. Les signes fonctionnels les plus fréquemment retrouvés étaient l'amaigrissement, les tremblements et les palpitations. La FT4 moyenne est de 54,51 ± 19,56ng/dl (extrêmes: 8,90-100). La TSHus moyenne de nos patients était égale 0,074 ± 0,29 µUI/ml. Les antithyroïdiens de synthèse ont été prescrits chez 49 patients avec une persistance d'une hyperthyroïdie dans 83,67% des cas. L'irathérapie a été prescrite en première intention dans 9,3% et en 2ème intention dans 90,7% des cas. L'activité moyenne était égale à 13,29 mCi ± 1,46 avec des extrêmes allant de 10 à 15 mCi. Le premier contrôle hormonal post-irathérapie, réalisé après un délai moyen de 1,91 mois, a montré une rémission (eu- ou hypo-thyroïdie) chez 29 patients soit 53,7%. Après 12 mois de suivi, l'évolution était marquée par une rémission dans 88,88% (euthyroïdie chez 14,8% et l'hypothyroïdie chez 74%). L'irathérapie est un traitement efficace de la maladie de Basedow. Une dose forfaitaire forte d'iode radioactif permet d'obtenir un taux de rémission élevé.

The XRD-pattern modelling, in the case of layered materials, provides an accurate structural characterization on the layer’s composition and the interlamellar space configuration. The layer type distribution, within the crystallite, is a key parameter and is considered as stacking defects affecting the researched best agreement between theoretical and experimental XRD profiles. This work investigates the effect of layer distribution type (mathematical functions) on the diffracted XRD theoretical intensity to optimize the final adopted model in the case of montmorillonite SWy-Na exchanged Barium. Obtained results showed that several distributions can be approved to carry out the 00ℓ reflection modelling.

The present study is a numerical simulation of natural convection in nanofluids, within in a square cavity differentially heated, to identify the fluid flow and heat transfer by considering the Soret effect during which a temperature gradient in a binary mixture gives rise to a concentration gradient. The governing equations solved numerically using the finite element method following the use of COMSOL Multiphysics. The effects of various parameters, the Rayleigh number, the nanoparticle concentration and the type of nanofluid are analyzed. Our simulations reveal that the heterogeneity of the nanofluid, which is generated by the Soret effect, increases the heat transfer.

The present work is a numerical simulation of the mixed convection of an incompressible fluid in a horizontal channel under sun radiation partially filled with metal foam blocks. The Darcy-Brinkman model is adopted. The control volume approach is used to solve the motion and energy equations governing mixed convection. The study focuses on the effect of certain control parameters such as the Rayleigh number (Ra), the thermal conductivity ratio and the porosity on the flow structure and heat transfer. Indeed, the results for flow structures and temperature distribution are presented in the form of velocity fields with streamtraces and isotherms, while the average Nusselt number (Nu) is used to quantify heat transfer.

In 2008-2009, the Archeopole company conducted a preventive excavation on a 1.6 ha area, in the Mureaux quarry, at Authevernes (Eure). This operation, the last of a series of archaeological investigations on this site since the mid-1990s, uncovered the remains of an ancient sanctuary. The excavations helped define this cult place’s establishment and functioning chronology between the Tibero-Claudian era and the first decades of the 3rd c. AD. They also permitted some reflections on its status and gave the opportunity to study different traces of cult activity highlighted into the sanctuary: banquets, sacrifices, ritual pits, sediments… These vestiges are diverse and sometimes hard to interpret, but it seems this place was a small rural sanctuary, linked to one or several villae and structured in several cultual activity places. There remains the question of Gallic presence under the sanctuary and of its precise nature.
