Seagrass meadows are major carbon sinks, trapping about 10% of the total CO2 sequestrated in the oceans. In the Mediterranean, a major focus has been made on the climax species Posidonia oceanica (L.) Delile, while other species remained little studied. In the framework of the STARECAPMED project, we thus chose to study Cymodocea nodosa (Ucria) Ascherson, a pioneer species with a rapid turnover and an expected high stocking capacity. Furthermore, the area covered by that species has been largely underestimated. In order to fill these two knowledge gaps, we first mapped all seagrass habitats within a Mediterranean bay (Calvi, Corsica, France) using side scan images, aerial photographs and ground truths. This cartography was followed by seasonal in situ density measurements and non-destructive shoot sampling (leaf cutting). Samplings were performed at different depths (5 to 23 m depth) in 6 contrasted stations (small patchy meadows to continuous beds) in order to cover all the existing facies of the bay. Elementary contents (carbon, nitrogen and stable isotope ratios) were measured in laboratory. This first work shows that C. nodosa meadows in Calvi Bay cover an area of 0.498 km2. Carbon stocks of the leaves reached 0.25 tons in winter and 2.72 tons in summer. Their nitrogen contents showed a marked seasonality with a maximum value of 0.020 mgN.m-2 in July and a minimum value of 0.005 mgN.m-2 in March. Some modifications in the trophic conditions of the water column at several stations were put in an obvious through the N stable isotopes values, mostly during the summer period. The actual underestimation of the area covered by that species in Calvi Bay has been properly mapped thanks to side scan sonar techniques revealing, together with elementary content analysis, its importance in the carbon balance of coastal areas.

The outcrops made by the incision of the Hoyoux and its tributaries have largely favored the opening of numerous quarries and some mines, in parallel with the installation of various transforming industries. The list of materials exploited is impressive: limestones, dolomites, sandstones and quartzites, conglomerates, clays, sands, iron ores, etc. Their exploitation required an abundant labor force. The quarries were predominantly located in the bottom of the valley, which allowed the establishment of vast and high operating fronts and the extraction of healthy stones, in particular ornamental stones which were declined in different chromatic varieties. Walking today through this popular wooded and bucolic valley, one hardly imagines the industrious activity where resonated the noise of the tools and the labor of the workers. [less ▲]

The Hoyoux hydrographic basin comprises two regions characterized by karstic phenomena and a rich hydrologic potential. On the one hand, the Condroz, where the Dinantian limestones are in synclinal position in the bottom of depressions, separated from one another by anticlinal crests which are occupied by the Upper Famennian sandstones. On the other hand, the narrow strip of Devonian limestones (of Givetian and Frasnian ages), positioned immediately at the NW of the previous region, separates the Condroz, which is constituted by an alternation of deposits of Famennian and Dinantian (sandstones and limestones) and, the Ardennes Condroz, which consists of lower devonian and eifelian deposits (conglomerates, quartzites, sandstones and schists). Since 2015, the Walloon Public Service's site "WalOnMap", using the ultra-precise digital terrain model "MNT 2013-2014 Hillshade" obtained after a LIDAR scan of the soil surface, offers a remarkable mapping tool essential to geological mapping, in general, and to the cartography and prospection of Karstic phenomena in particular.

This text investigates the connexion between the work of Charles Goodwin and contemporary semiotics. I initially address the relations between verbal, visual, and gestural languages in semiotic terms by exploring the Goodwin’s notational system (transcription of exchanges) from the point of view of its constituent units. Secondly, I consider the meeting points between Goodwin’s concept of the substrate and Fontanille’s enunciative praxis in order to examine the dynamic relationship between sedimentation and transformation. Finally, I analyse the concept of diagrammatic reasoning by elaborating on the example of the geologists’ “first inscriptions” studied by Goodwin. The form of diagrammatic reasoning examined here functions as a discovery device that exemplifies the dynamics of sedimentation and novelty, and it can thus be studied in the framework of Goodwin’s transcription practices.

Dans les réflexions récentes portant sur l’organisation du travail en entreprise, nombreux sont les auteurs qui s’intéressent à la question des « nouvelles formes d’organisation ». Sous cette appellation se rassemblent des courants aux dénominations différentes (entreprise libérée, entreprise virtuelle, « holacracie »…) partageant cependant des principes fondateurs communs (tels que la flexibilité, l’autonomie du collaborateur ou encore la digitalisation des pratiques de travail). A travers une étude de trois mois au sein d’un département de protection juridique d’une importante compagnie d’assurances située à Bruxelles, nous étudions un projet de changement basé sur le « New Way of Working » (NWoW) – un chantier managérial se développant principalement aux Pays-Bas et en Belgique depuis une dizaine d’années, proposant une « nouvelle » vision des travailleurs dans le secteur tertiaire. Nous rendons compte des trois composantes clés du projet NWoW telles qu'il est problématisé dans notre étude de cas: les Bricks (travail en open-space, bureaux flexibles, travail à distance), les Bytes (nouveaux outils numériques, travail sans papier, connectivité) et les Behaviors (autonomie et responsabilité des collaborateurs, passage du contrôle à la confiance). Nous concluons par une réflexion structurée autour des "4C": dans ces nouveaux environnements de travail, de nouvelles questions émergent en termes de confiance, de contrôle, de cohésion et de coordination.

Régulièrement recommandé à des fins préventives ou curatives, le repos vocal favorise la récupération dans différentes circonstances. Bon nombre de phonochirurgiens l’incluent dans les soins postopératoires, avant une éventuelle prise en charge orthophonique. Le repos vocal permet également de résorber une simple fatigue ressentie suite à un usage intensif ou inhabituel de la voix, ou peut faire l’objet d’une indication thérapeutique dans le cadre de lésions consécutives aux phonotraumatismes. Compte tenu du manque de données scientifiques et de la diversité des pratiques sur le sujet, il n’est pas toujours aisé de donner des indications claires aux patients, souvent réticents à l’idée de ne pas pouvoir utiliser leur voix pendant une durée prolongée. Basé sur des recherches récentes et sur des expériences cliniques, ce chapitre permet de mieux comprendre l’intérêt du repos vocal et suggère des lignes de conduites quant à la manière de l’organiser [less ▲]

Dans ce chapitre, nous présentons la voix du point de vue du genre. En effet, l’Unité Logopédie de la Voix (www.logopedie-voix.be) s’intéresse entre autres à la féminisation vocale chez les personnes transidentitaires, en processus de changement de genre. Ces personnes ne s’identifiant pas au sexe et au genre qui leur ont été attribués à la naissance, elles éprouvent un désir profond de vivre comme une personne du sexe opposé à leur sexe biologique. Lors du processus de transition où ont lieu les transformations nécessaires au changement de genre, l'orthophonie a pour but d’améliorer la cohérence entre l’apparence de la personne et sa voix. Ainsi, notre recherche se focalise sur ce qui distingue la voix féminine de la voix masculine. Nous visons à développer des stratégies de féminisation vocale, portant sur des paramètres tels que la fréquence fondamentale de la voix, les formants, les contours intonatifs, le débit de parole, le rythme, ou encore le vocabulaire choisi. Féminiser une voix, c’est chercher à comprendre ce qui permet d’en identifier le genre, mais également participer à la construction de l’identité de la personne à part entière. [less ▲]

Introduction : Severe limb deficiencies have been reported in association with bilateral renal agenesis in several syndromes. Recently, truncating mutations in LRP4 have been associated with a lethal autosomal recessive form of Cenani-Lenz syndrome (CLS). The objectives of our study was to delineate the phenotype of the third fetus, and through a search of syndromes, identify a group of disorders with overlapping phenotypes that may be allelic with CLS or due to mutations in the same pathway. Results : A male fetus at 22 weeks’ gestation was found to have bilateral renal agenesis by ultrasound. The pregnancy was interrupted and autopsy and skeletal survey revealed shortening of forearms and legs below the knees, radioulnar synostosis, foreshortened triangular shaped tibia and fibula, and oligosyndactyly with disorganized metacarpals, metatarsals and phalanges. Bilateral renal agenesis, absent ureters and small bladder were confirmed. Additional features included downslanting palpebral fissures, high-arched palate, small mouth, low-set and posteriorly rotated ears, nuchal oedema, pulmonary hypoplasia, hypospadias and absent olfactory nerves. An autosomal recessive disorder was suspected, given a prior obstetric history of termination at 18 weeks for unilateral limb anomalies and cleft lip. Based on the aforementioned renal and limb anomalies, the lethal form of CLS was considered. Sequencing of LRP4 identified a paternally inherited variant (c.919+3G del) and a maternally inherited variant (c.4808T>A ;p.Ile1603Val). Both variants were rare in the general population and bioinformatically predicted to be damaging. We compared the phenotype with the two previously reported fetuses as well as with syndromes and disorders that may present prenatally with genitourinary anomalies plus acromesomelia of upper and lower limbs. We found significant overlap with a subset of cases of acro-renal-uterine-mandibular syndrome presenting with high-arched palate plus or minus micrognathia and microglossia, severe limb anomalies affecting the middle and distal segments, oligosyndactyly, renal agenesis, uterine anomalies and absence of olfactory nerves. Conclusion : Based on the clinical features seen in three lethal cases of CLS, we propose that acro-renal-uterine-mandibular syndrome may be allelic with CLS or due to mutations in the molecular pathway involving LRP4.

2 | P. Delanaye et al. Abstract A reliable assessment of glomerular filtration rate (GFR) is of paramount importance in clinical practice as well as epidemiological and clinical research settings. It is recommended by Kidney Disease: Improving Global Outcomes guidelines in specific populations (anorectic, cirrhotic, obese, renal and non-renal transplant patients) where estimation equations are unreliable. Measured GFR is the only valuable test to confirm or confute the status of chronic kidney disease (CKD), to evaluate the slope of renal function decay over time, to assess the suitability of living kidney donors and for dosing of potentially toxic medication with a narrowtherapeutic index. Abnormally elevatedGFRor hyperfiltration in patients with diabetes or obesity can be correctly diagnosed only by measuring GFR. GFR measurement contributes to assessing the true CKD prevalence rate, avoiding discrepancies duetoGFRestimation with different equations. Usingmeasured GFR, successfullyaccomplished in large epidemiological studies, is the onlyway to study the potential link between decreased renal functionand cardiovascular or total mortality, being sure that this association is not due to confounders, i.e. non-GFR determinants of biomarkers. In clinical research, it has been shown that measured GFR (or measured GFR slope) as a secondary endpoint as compared with estimated GFR detected subtle treatment effects and obtained these results with a comparatively smaller sample size than trials choosing estimated GFR. Measuring GFR by iohexol has several advantages: simplicity, low cost, stability and low interlaboratory variation. Iohexol plasma clearance represents the best chance for implementing a standardized GFR measurement protocol applicable worldwide both in clinical practice and in research. [less ▲]
