Macellomenia profundorum n. sp. (Mollusca, Solenogastres, Pholidoskepia) a new abyssal species from the South Atlantic Ocean (Angola Basin)
No full textA new species of solenogaster (Mollusca, Aplacophora) from the Angola Basin is described: Macellomenia profundorum n. sp. The studied specimen was collected during the DIVA 1 expedition (Latitudinal Gradients of Deep-Sea BioDIVersity in the Atlantic Ocean). The description is based primarily on the sclerites and the internal anatomy (histological study). Macellomenia profundorum n. sp. is the first species of the family to be described from the southern hemisphere and constitutes its deepest record (5400 m deep). Even though only anterior anatomical characters are known, these and especially the radula and mantle sclerites are enough to justify that it is a new species. Amended diagnoses are also provided for the family and genus
Determination of the Interaction Depth Caused by Stress Peening at Leaf Springs
No full textStress peening is a normal production step in leaf spring production. It enhanced the compressive residual stresses in the spring. The question that arises is what the amount is caused by shot peening and on the other hand coming from the prestress. A subtraction of the residual stresses along the leaf and perpendicular in dependence of the depth shows the increase. One result is a section that shows the limit of the maximal inducible residual stress. that is two-thirds of the tensile strength. The depth of the interaction is depended on the energy of the shots, the hardness of the shots, and the component to be shot peened. If the preload for peening is up to the tensile strength, depths of more than 500 µm are suitable for leaf springs. This method can be also done for coil or disk springs.Funding: Research Fund for Coal and Steel, Grant Agreement No 79978
Transforming wastewater treatment plants into reclaimed water facilities in water-unbalanced regions. An overview of possibilities and recommendations focusing on the Italian case
No full textWater scarcity will be one of the most challenging topics to cope with in the following years, especially in the regions most affected by climate change such as the Mediterranean basin. The implementation of water reuse practices thus appears essential to satisfy future water demands in a sustainable way, helping to reduce hydric stress in water-unbalanced regions. However, it remains as an underused practice. To change this situation, the wastewater sector needs to develop some structural changes that include not only the transformation of conventional wastewater treatment plants (WWTPs) into novel reclaimed water facilities (RWF), but also some paradigm shifts regarding social, political and legal factors. The goal of this manuscript is to provide a systemic, novel and updated vision of the wastewater treatment sector and to give some recommendations for the implementation of wastewater reuse in agriculture, with a special focus on the Italian case. Extensive data regarding water reuse technologies for the refining, disinfection and advanced oxidation of wastewater is also provided. This comprehensive analysis could help to align the objectives to be achieved from all the perspectives (technical, economic, legal and socio-political), thus helping to fill current gaps and overcome barriers that hinder water reuse development

No full text<p>Issu de la gestion de l’aménagement du territoire et du parcours de vie des bâtiments, le jumeau numérique 3D est un outil déjà bien défini avec des formats interopérables, standardisés et des chaînes opératoires/process éprouvés (collaboratives, traçabilité des fichiers et de leurs modifications, etc.).</p>
<p>Le présent projet de collaboration institutionnel se propose d’appliquer le maquettage 3D pour fournir, non pas une cinématique 3D esthétisante de plus, mais un véritable S.I.G 3D aux potentialités d’études immersives importantes. Un outil en quatre dimensions (référentiel euclidien et variable temporelle), regroupant les problématiques de conservation et de recherche, est, désormais, indispensable pour la gestion conservatoire et scientifique de la grotte Cosquer (Marseille, Bouche du Rhône.</p>
<p>Les précédentes preuves de concept issues de projets SHS ont prouvé la pertinence de lier l’expertise du CSTB aux objets patrimoniaux numériques issus de la recherche en sciences humaines et sociales. Le retour d’expérience du CSTB face à l’étude de la résistance et du vieillissement des matériaux sera, tout particulièrement, attendu face aux problématiques de conservation de « Cosquer ».</p>
<p>Cette mise en place numérique peut, également, palier à la grande difficulté d’accès à « Cosquer » et au temps d’intervention très réduit in situ. Autant immergé que submergé, l’espace d’étude sera celui du gisement archéologique et de la zone immédiatement autour de ce dernier. La création du jumeau numérique « Cosquer » permettra le travail collaboratif des différents personnels scientifiques et des organismes collaborant aux études actuelles ou à venir (Inrap, CNP, Musées, MCC, LAMPEA, AMU, SRA, etc.).</p>
<p>Découverte probablement au milieu des années 1980, la grotte Cosquer a été déclarée par son inventeur, Henri Cosquer, en septembre 1991. L’accès est aujourd’hui submergé en raison de la remontée du niveau marin depuis la fin du Pléistocène. Situé sur la commune de Marseille, le site a été classée au titre des Monuments historiques le 2 septembre 1992.</p>
<p>Il s’agit d’un des sites majeurs à dispositifs pariétaux du Paléolithique supérieur européen en raison de la richesse, de la diversité et de l’originalité des manifestations graphiques pariétales. En l’état actuel des connaissances, le cadre chronologique des fréquentations humaines a été appréhendé par une quarantaine de datations radiocarbones. Ces mesures radiocarbones fournissent un premier cadre chronologique qui s’échelonne sur près de 11 millénaires (entre 27 000 et 16 000 BP non cal.). Comme plusieurs grottes ornées du Paléolithique supérieur, la grotte Cosquer témoigne ainsi d’un palimpseste de comportements, de gestes artistiques, techniques, fruit des multiples sociétés humaines venues y laisser leurs traces.</p>
<p>On décompte aujourd’hui plusieurs centaines d’entités graphiques peintes et gravées, zoomorphes (chevaux, bouquetins, bisons et de cervidés) et anthropiques avec de nombreuses empreintes de mains. Si la représentation d’espèces marines reste minime sur les parois de la cavité (env. 3% du total des entités), elle marque néanmoins une originalités de ce site dont le littoral se situait, au plus près, à environ 6 km de distance lors du dernier maximum glaciaire.</p>
<p>Les données archéologiques des parois et des sols de la grotte Cosquer sont les seuls à ce jour qui permettent d’offrir le potentiel d’analyse pour une confrontation technique, iconographique et anthropologique des schèmes symboliques et des traditions techniques des sociétés humaines paléolithiques de l’Europe atlantique et méditerranéenne.</p>
<p>Pour aider à la préparation des travaux et pour enregistrer et croiser les résultats des différents champs scientifiques réunis dans l’équipe scientifique Cosquer (archéologues, géomorphologues, hydrogéologie,...), le modèle 3D de la grotte est combiné aux bases de données géospatiale d’enregistrement scientifique.</p>
AN IPA APPROACH TO A MINDFULNESS MEDITATION INTERVENTION
No full textMindfulness meditation (MM) interventions, such as Mindfulness-based stress reduction (MBSR), have been shown to reduce stress and anxiety in many university student samples. Practicing MM over long periods of time increases levels of trait mindfulness (TM), characterized by a general decrease in daily stress and anxiety levels and a proliferation of positive mindfulness habits and attitudes. Thus, understanding how to optimally increase TM levels across time can be highly beneficial for university students. However, studies, measures, and models explaining the nature of TM have produced many different paradigms, some of which are restrictive.
The present study utilized interpretative phenomenological analysis (IPA) methodology to explore the experiences of two university student participants in a 12-week MM intervention adapted from an official MBSR program. The IPA interview process revealed potentially salient components of TM based on the habits and trends that participants implemented into their daily lives as a result of the MM program. Results of the IPA highlight the need for a versatile model of TM which can evolve as future researchers propose new and substantiate existing facets
