Observed evolution of the total mass distribution with redshift is crucial to testing galaxy evolution theories. To measure the total mass distribution, strong gravitational lenses complement the resolved dynamical observations that are currently limited to z ≲ 0.5. Here we present the lens models for a pilot sample of seven galaxy-scale lenses from the ASTRO3D Galaxy Evolution with Lenses (AGEL) survey. The AGEL lenses, modeled using HST/WFC3-F140W images with Gravitational Lens Efficient Explorer (GLEE) software, have deflector redshifts in the range 0.3 < z
defl < 0.9. Assuming a power-law density profile with slope γ, we measure the total density profile for the deflector galaxies via lens modeling. We also measure the stellar velocity dispersions (σ
obs) for four lenses and obtain σ
obs from SDSS-BOSS for the remaining lenses to test our lens models by comparing observed and model-predicted velocity dispersions. For the seven AGEL lenses, we measure an average density profile slope of −1.95 ± 0.09 and a γ–z relation that does not evolve with redshift at z < 1. Although our result is consistent with some observations and simulations, it differs from other studies at z < 1 that suggest the γ–z relation evolves with redshift. The apparent conflicts among observations and simulations may be due to a combination of (1) systematics in the lensing and dynamical modeling; (2) challenges in comparing observations with simulations; and (3) assuming a simple power law for the total mass distribution. By providing more lenses at z
defl > 0.5, the AGEL survey will provide stronger constraints on whether the mass profiles evolve with redshift as predicted by current theoretical models.

Coronal Mass Ejections (CMEs), drivers of the most severe Space Weather disturbances, are often assumed to evolve self-similarly during their propagation. However, open magnetic field structures in the corona, leading to higher-speed streams in the ambient solar wind, can be source of strong distortions of the CME front. In this paper, we investigate a distorted and Earth-directed CME observed on 2022 March 25 combining three remote sensing with three in situ observatories at different heliocentric distances (from 0.5 to 1 au). Near quadrature observations by Solar Orbiter and the Solar Terrestrial Relations Observatory revealed a distortion of the CME front in both latitude and longitude, with Solar Orbiter observations showing an Earth-directed latitudinal distortion as low as ≈6 R
⊙. Near-Earth extreme-ultraviolet observations indicated the distortion was caused by interaction with faster wind from a nearby equatorial coronal hole. To evaluate the effect of the distortion on the CME's propagation, we adopted a three-point-of-view graduated cylindrical shell (GCS) fitting approach. For the first time, the GCS results are combined with an additional heliospheric single-viewpoint that looks further out in the heliosphere, revealing a deceleration in the CME before reaching ≈100 R
⊙. The CME geometry and velocity determined by this enhanced GCS are used to initialize a drag-based model and a WSA-Enlil MHD model. The estimated times of arrival are compared with in situ data at different heliocentric distances and, despite the complexity of the event, the error in the arrival times at each spacecraft results much lower (≈4 hr error) than the typical errors in literature (≈8–10 hr).

Published: July 2024

In this research, the effect of different productive stages of tilapia (Oreochromis niloticus) in a hyper-intensive aquaculture system on the growth of tomatoes was evaluated. Fish were cultivated in a final density of 80 kg m3 considering three development stages (an average of fingerling of 1.487 g, juvenile of 62 g, and adult of 203.75 g, respectively). The quality of water was measured by determining temperature, pH, electric conductivity, and dissolved oxygen. Biometric data were registered throughout the growth of fish and tomatoes. Results showed that the survival, growth, and health of fish are not affected by the hyper density of culture; as well as the quality water was maintained under acceptable conditions for the development of organisms. Besides, it was obtained that the early productive stages (fingerlings and juveniles) gave the best results for tomato growth. These results suggest using the wastewater from fingerlings and juveniles of a hyper intensive recirculation aquaculture system to produce hydroponic tomato; to achieve sustainable production systems with maximum use of the resources.

Published: July 2024

Coral reefs are ecosystems with great biodiversity and architectural complexity. Among these, marine fungi constitute one of the least studied groups, despite being potentially an inexhaustible source of bioactive metabolites. For this reason, in this research, we evaluate the antiproliferative activity of 52 fungal strains associated with marine organisms such as algae and coral collected from four islands located in the National Park Sistema Arrecifal Veracruzano, Mexico. One hundred four chloroform:methanol extracts corresponding to the culture broth, and biomass produced from each fungal strain was obtained from these. Subsequently, they were evaluated against six human solid tumor cell lines (HBL-100, HeLa, SW1573, T-47D, WiDr, and A549). The outcome was that six extracts showed activity against at least one cancer cell line. The identity of these fungi corresponded to the genera Nigrospora, Pestalotiopsis, Cladosporium, and Ochroconis according to their morphological and molecular analysis. In this sense, the strain found to have the highest antiproliferative potential [GI50 (μg mL-1) 4.6, 2.5, 8.0, 5.6, 52.0, 4.0] grouped phylogenetically with a species of Nigrospora sp. The preceding confirms that ecosystems provide.
Development and evaluation of curcumin-loaded vesicular carriers: impact of formulation variables
Authors: Momekova Denitsa , Gugleva Viliana , Petrov Petar
Published: July 2024

Vesicular carriers are a well-established approach to improving the technological and biopharmaceutical characteristics of the loaded cargo. The current manuscript is focused on the development and evaluation in a comparative aspect of two types of vesicles—ethosomes and transfersomes loaded with the phytoconstituent curcumin. The formulation variables affecting their physiochemical and cytotoxic properties are outlined as well. A series of ethosomes and transfersomes based on Lipoid S75 and ethanol, or edge activator, were prepared using the thin film hydration method and subjected to comprehensive evaluation by dynamic light scattering (DLS) analysis, transmission electron microscopy (TEM), entrapment efficiency evaluation, in vitro release, and cytotoxicity studies. Ethosomes based on Lipoid S75 (4% w/w) and ethanol (30% v/v) showed suitable physicochemical characteristics (hydrodynamic diameter of 578.6 nm, monomodal size distribution, high curcumin entrapment efficiency (78.2%)), and superior antiproliferative activity compared to free drug and transfersomal nanocarriers.
Le concept du patient partenaire, de l’implicite vers l’explicite
Authors: Psiuk Thérèse
Published: July 2024

Le concept du patient partenaire devient de plus en plus explicite depuis la loi du 4 mars 2002 relative aux droits des malades et à la qualité du système de santé. Au-delà des qualités humaines d’écoute et d’empathie, la relation de partenariat oblige le professionnel de santé à créer en permanence le lien de confiance. La médecine narrative est de plus en plus réhabilitée en laissant le patient raconter ce qu’il vit, en lui transmettant des informations simples adaptées à son niveau de compréhension et à son parcours de vie. Ce patient devient acteur de sa santé en participant à la co-construction du raisonnement clinique et de la dynamique d’adaptation des soins. Les savoirs d’expérience complémentaires au savoir scientifique sont recueillis sous une forme quantitative mais également qualitative à partir des verbatim identifiés dans les récits d’expériences.
Apports d’une épreuve de dessin en réalité virtuelle au bilan projectif

Published: July 2024

Le bilan psychologique numérique, sans prétendre remplacer les méthodes traditionnelles, mérite d’être étudié afin de mettre en évidence plus précisément ses limites mais aussi sa richesse potentielle en fonction des situations cliniques spécifiques où il se déploie. Dans cet article, nous proposons une présentation clinique d’un cas unique afin de mettre en lumière les spécificités d’un dessin en réalité virtuelle dans le cadre d’un bilan psychologique complet, composé d’un test de Rorschach, d’un TAT (Thematic Apperception Test), d’un scéno-test, d’un dessin libre, et d’un dessin libre en réalité virtuelle. Grâce à ce cas unique, nous avons mis en évidence le potentiel d’intégration d’une évaluation du dessin en réalité virtuelle dans une évaluation projective complète. Immergé dans la réalité virtuelle, le sujet est moins conformiste, c’est-à-dire moins confiné par les normes sociétales et moins inhibé par les pressions normatives du surmoi. Cela permet aux cliniciens d’accéder à un aspect qui peut ne pas être aussi apparent dans d’autres évaluations. Nous avons exploré les premières pistes de complémentarité avec les évaluations traditionnelles et espérons ouvrir de nouveaux champs de recherche pour améliorer les soins aux patients. De fait, les spécificités d’une épreuve de dessin en réalité virtuelle constituent des pistes sérieuses pour une médiation thérapeutique.
Un monde livré à la corruption
Authors: Monier Frédéric
Published: July 2024

De nombreuses organisations internationales s’alarment, depuis le début du XXI e siècle, des progrès de la corruption dans le monde. Or, loin d’être nouveau, ce phénomène remonte à plusieurs siècles. Revenir sur sa genèse permet de comprendre que le terme n’a pas toujours eu le sens que nous lui donnons aujourd’hui, et que les réponses apportées à ce fléau ont varié au fil du temps. Ces réponses partaient souvent du principe selon lequel la vertu et le progrès chasseraient la corruption. Tout indique au contraire que les processus de modernisation eux-mêmes engendrent de nouvelles pratiques de corruption qui alimentent à leur tour les débats sur la moralité des hommes au pouvoir .
La cybercriminalité et ses enjeux
Authors: Fortin Francis
Published: July 2024

Au cours de la dernière décennie, le monde virtuel a connu une véritable gangstérisation avec l’essor de réseaux d’individus se regroupant pour commettre de nombreux cybercrimes lucratifs, comme l’hameçonnage (phishing) ou le rançongiciel (ransomware) . Cette économie souterraine est portée par trois éléments principaux : la nouvelle division des tâches à l’ère du numérique, qui permet désormais à tout acteur criminel d’agir comme une véritable entreprise ; l’utilisation du dark web (web clandestin), qui permet aux cybercriminels de se rencontrer et de vendre un vaste éventail de produits et de services illicites ; l’utilisation de cryptomonnaies pour l’échange sécurisé de ces biens et services .
Un front multi-dimensionnel pour contrer les réseaux de traite des êtres humains
Authors: Tor Erwann
Published: July 2024

La traite des êtres humains désigne le processus visant à exploiter une personne en utilisant des moyens de contrainte ou en abusant de sa vulnérabilité. La lutte contre les réseaux de traite des êtres humains trouve tout son sens dans la protection des victimes. L’amélioration de leur prise en charge et de la réparation de leur préjudice passe par le renforcement de leur identification au niveau mondial. Dans un contexte international de conflits armés et de crise climatique qui accroît les flux migratoires et les opportunités pour les trafiquants, les réponses à ce fléau sont d’ordre politique, mais pas seulement. Aux côtés des acteurs publics et des organisations internationales, c’est l’ensemble de la société civile qui doit être sensibilisé et responsabilisé .
Boston et ses films noirs : gangsters, informateurs et conflits de loyauté

Published: July 2024

Ville riche de ses universités prestigieuses, de ses laboratoires de recherche et entreprises de la finance ou de la Tech, Boston a longtemps connu une criminalité redoutable que les caméras de Hollywood ont su raconter au long de plusieurs films noirs. Si nombre de ces œuvres ont dépeint en particulier la communauté populaire d’origine irlandaise, gangrenée un temps par une violence endémique et de puissants gangsters, d’autres se sont attardées sur des figures célèbres du crime, comme l’étrangleur de Boston. Toutes soulignent la relative impuissance des forces de l’ordre, jusqu’au tragique attentat qui a frappé la ville en 2013 .
À l’école de l’éthique
Authors: Claeys Sébastien
Published: July 2024

Les nombreux avatars de l’éthique appliquée qui peuvent donner lieu à des formations, des comités, des débats, ou encore des chartes, questionnent aujourd’hui les modalités de transmission de l’éthique. Alors que ces modes de transmission de la démarche de réflexion éthique sembleraient nous dévoyer d’une conception de l’éthique plus traditionnelle, ils nous permettent, au contraire, de revenir aux sources même de ce qu’est l’éthique comme pensée pratique. Envisager l’éthique au prisme de ses modes de transmission est donc une formidable occasion de revisiter les grandes pensées de l’éthique, de questionner les savoirs en éthique, et la nature même de cette transmission. Après une présentation générale de la problématique du dossier, nous exposons ici l’ensemble des articles des contributeurs.
L’hôpital : un environnement d’apprentissage de l’éthique ?

Published: July 2024

Le champ de la santé connaît de profondes innovations (thérapeutiques, sociales, organisationnelles, structurelles) qui modifient le besoin en matière d’éthique. Celle-ci ne peut plus se limiter à analyser des situations-problèmes complexes dans une visée de conformation aux normes ou de production d’un discours moral à propos des pratiques. « Faire de l’éthique », c’est se rendre capable d’initier de nouvelles pratiques en contexte à partir d’une démarche d’expérimentation sociale. Le pragmatisme constitue de ce fait une ressource théorique pertinente pour fonder les pratiques contemporaines de l’éthique. Dans ce cadre, l’éthique s’apparente à un projet d’apprentissage collectif visant la capacitation des acteurs et des organisations ainsi qu’une gouvernance réflexive et participative de leur agir. Dans cet article, nous présentons un projet (l’actualisation du projet de soins d’un établissement de santé) qui s’inscrit dans un programme institutionnel d’activités en éthique, et qui mobilise la démarche living lab comme méthodologie de travail. Quatre-vingt-onze professionnels de l’établissement se sont retrouvés dans des ateliers thématiques pour partager et analyser leur expérience et construire un programme d’actions visant à mettre en œuvre, dans les cinq ans, les grandes orientations du projet de soins. L’objectif de cet article, outre la présentation du dispositif, est de tirer les premiers enseignements du travail réalisé et d’analyser la nature des apprentissages générés par cette dynamique d’intelligence collective.
Fabrication du corps et éthique de la transmission dans la formation des infirmiers
Authors: Beaudoin-Denissel Camille
Published: July 2024

Les infirmiers et les étudiants s’enfuient. Leurs corps, engagés dans la sollicitude pour l’autre, souffrent, démissionnent. Ils souffrent de dilemmes éthiques pour s’occuper des malades, ils souffrent aussi de se sentir « inhumains » . Il semble urgent de regarder comment nous traitons le corps et ce que nous lui faisons au cours de la fabrique éducative. À travers les récits d’expériences des étudiants infirmiers, cet article explore un phénomène souterrain dans la formation des infirmiers. Il s’agit de dévoiler la fabrication d’un corps standardisé comme modèle idéal type de l’infirmier dans l’espace classe, d’en montrer la puissance normative puis de faire apparaître les effets de ce modèle sur la vie des personnes dans l’espace du soin. Le rapport à la norme, le sensible, la déviance, la culpabilité et les mécaniques de « dressage du corps » sont examinés sous l’œil de ce que je nomme une éthique de la transmission .
Formation éthique à l’expérience du soin et obstacles disciplinaires : comment relever le défi ?
Authors: Eggert Nadja , Landheer-Cieslak Christelle , Benaroyo Lazare , Freeman Andrew
Published: July 2024

Le soin – et le terme est à comprendre dans un sens élargi en intégrant les soins de santé et de services sociaux – ne peut se réduire à un geste technique. Il implique une responsabilité éthique du soignant face à l’expérience existentielle de la souffrance du patient. En effet, tout acte de soin ne peut prendre sens qu’au cœur de cette irréductible altérité intersubjective qui s’inscrit dans une altérité institutionnelle plus large, nourrie par un cadre philosophique, politique et juridique toujours singulier. Dans la pratique du soin, cette mise en sens est généralement indissociable d’une démarche éthique. En effet, face à la complexité du réel, une délibération entre les soignants est le plus souvent nécessaire pour prendre en charge de manière responsable le patient en se centrant sur son vécu et sa manière unique d’être au monde tout en respectant les valeurs collectives, notamment celles qui se sont cristallisées dans les textes juridiques encadrant et guidant la relation de soin dans une société donnée. Une telle démarche, de plus en plus en demande dans les milieux de soins, se révèle toutefois complexe. Par sa nécessaire interdisciplinarité, elle suppose une mise en dialogue de diverses identités professionnelles issues, par exemple, du domaine de la santé, des services sociaux, de l’éthique et du droit. Or, chacune de ces identités, en raison de la formation universitaire et de l’organisation professionnelle, présente le plus souvent la particularité d’être constituée en silo, parfois très hermétique. Dès lors, comment sortir de cette impasse, tout particulièrement lors d’une délibération éthique entre intervenants de différentes disciplines engagés dans une expérience du soin ? Notre équipe interdisciplinaire (médecine, ergothérapie, droit et éthique) et interculturelle (Canada et Suisse) s’efforce de répondre à cette question en proposant des enseignements collaboratifs. Ces expériences d’enseignement sont l’objet du présent article.

Published: July 2024

The widespread use of computer hardware and software in society has led to the emergence of a type of criminal conduct known as cybercrime, which has become a major worldwide concern in the 21st century spanning multiple domains. As a result, in the present setting, academics and practitioners are showing a great deal of interest in conducting research on cybercrime. In this work, a fractional-order model was replaced by involving three sorts of human populations: online computer users, hackers, and cyber security professionals, in order to examine the online computer user-hacker system. The existence, uniqueness and boundedness were studied. To support our theoretical conclusions, a numerical analysis of the influence of the various logical parameters was conducted and we derived the necessary conditions for the different equilibrium points to be locally stable. We examined the effects of the fear level and refuge factor on the equilibrium densities of prey and predators in order to explore and understand the dynamics of the system in a better way. Using some special circumstances, the model was examined. Our theoretical findings and logical parameters were validated through a numerical analysis utilizing the generalized Adams-Bashforth-Moulton technique.

By using linear, bilinear, and trilinear estimates in Bourgain-type spaces and analytic spaces, the local well-posedness of the Cauchy problem for the a Kawahara-Korteweg-de-Vries equation

   \begin{document}$ \partial_{t}u+\omega\partial_{x}^{5}u+\nu \partial_{x}^{3}u+\mu\partial_{x}u^{2}+\lambda\partial_{x}u^{3}+\mathfrak{d}(x)u = 0, $\end{document}

was established for analytic initial data $ u_{0} $. Besides, based on the obtained local result, together with an analytic approximate conservation law, we prove that the global solutions exist. Furthermore, the analytic radius has a fixed positive lower bound uniformly for all time.

The aim of this note is to study the Cauchy problem for the 2D Euler equations under very low regularity assumptions on the initial datum. We prove propagation of regularity of logarithmic order in the class of weak solutions with $ L^p $ initial vorticity, provided that $ p\geq 4 $. We also study the inviscid limit from the 2D Navier-Stokes equations for vorticity with logarithmic regularity in the Yudovich class, showing a rate of convergence of order $ |\log\nu|^{-\alpha/2} $ with $ \alpha > 0 $.
Statistical Analysis of Features for Detecting Leukemia
Authors: Khobragade Vandana S. , Nirmal Jagannath H. , Hakim Aayesha
Published: July 2024

In this age of digital microscopy, image processing, statistical analysis, categorization, and systems for decision-making have become essential tools for medical diagnostics research. By visualizing and analyzing images, clinicians can identify anomalies in intracellular structure. Leukemia is a cancerous condition marked by an unregulated increase in aberrant white blood cells (WBCs). Recognizing acute leukemia tumor cells in blood smear images (BSI) is a challenging assignment. Image segmentation is regarded as the most significant step in the automated identification of this disease. The innovative concavity-based segmentation algorithm is employed in this study to segment WBC in sub-images from the ALLIDB2 database. The concave endpoints and elliptical features are used in the segmentation step of convex-shaped cell images. The procedure involves the extraction of contour evidence, which detects the visible section of each object, and contour estimation, which corresponds to the final object’s contours. Following the identification of the cells and their internal structure by concavity-based segmentation, the cells are categorized based on their morphological and statistical features. The method was evaluated using a public dataset meant to test classification and segmentation approaches. The statistical tool SPSS is used to independently check the significance of derived features. For classification, significant features are passed into machine learning techniques such as support vector machines (SVM), k-nearest neighbor (KNN), neural networks (NN), decision trees (DT), and Nave Bayes (NB). With an AUC of 98.9% and a total accuracy of 95%, the neural network model performed better. We advocate using the neural network model to identify acute leukemia cells based on its accuracy.
An Algorithm for the Estimation of Hemoglobin Level from Digital Images of Palpebral Conjunctiva Based in Digital Image Processing and Artificial Intelligence
Authors: Moreno Guillermo , Camargo Abdigal , Ayala Luis , Zimic Mirko , Del Carpio Christian
Published: July 2024

Anemia is a common problem that affects a significant part of the world’s population, especially in impoverished countries. This work aims to improve the accessibility of remote diagnostic tools for underserved populations. Our proposal involves implementing algorithms to estimate hemoglobin levels using images of the eyelid conjunctiva and a calibration label captured with a mid-range cell phone. We propose three algorithms: one for calibration label segmentation, another for palpebral conjunctiva segmentation, and the last one for estimating hemoglobin levels based on the segmented images from the previous algorithms. Experiments were performed using a data set of children’s eyelid images and calibration stickers. An L1 norm error of 0.72 g/dL was achieved using the SLIC-GAT model to estimate the hemoglobin level. In conclusion, the integration of these segmentation and regression methods improved the estimation accuracy compared to current approaches, considering that the source of the images was a mid-range commercial camera. The proposed method has the potential for mass screening in low-income rural populations as it is non-invasive, and its simplicity makes it feasible for community health workers with basic training to perform the test. Therefore, this tool could contribute significantly to efforts aimed at combating childhood anemia.

Published: July 2024

Neurodegenerative disorders, notably Alzheimer’s, pose an escalating global health challenge. Marked by the degeneration of brain neurons, these conditions lead to a gradual decline in nerve cells. Worldwide, over 55 million people grapple with dementia, with Alzheimer’s prominently impacting the aging demographic. The primary hurdle to early Alzheimer’s detection is the widespread lack of awareness. The main goal is to design and implement an artificial intelligence system using deep learning (DL) to detect Alzheimer’s disease (AD) through medical images and classify them into various stages, such as non-demented, moderate dementia, mild dementia, and very mild dementia. The dataset contains 6400 magnetic resonance images in .jpg format, with standardized dimensions of 176 × 208 pixels. To demonstrate the advantages of data augmentation and transformation techniques, four scenarios were created: two without these techniques, utilizing the Adam and SGD optimizers, and two with these techniques, also employing the Adam and SGD optimizers, respectively. The main results revealed that scenarios utilizing these techniques exhibited more stable performance when validated with a new dataset. Scenario 3, using the Adam optimizer, achieved a weighted average accuracy of 91.83%, whereas scenario 4, employing the SGD optimizer, reached 87.58% accuracy. In contrast, scenarios 1 and 2, which omitted these techniques, obtained low accuracies below 55%. It is concluded that classifying AD with a DL model exceeding 90% accuracy is feasible. This is the importance of utilizing data augmentation and transformation techniques to improve generalizability to input image variations, which is a consistent factor in the healthcare sector.
Fabrication of TiO2 Nanoparticle Coating on Stainless Steel 316L and Its Assessment for Orthopaedic Applications
Authors: Jadon Manjit Singh , Kumar Sandeep
Published: July 2024

The study aims to investigate the efficacy of titanium dioxide (TiO2) nanoparticle coating on stainless steel 316L (SS 316L) orthopaedic implants to enhance their biocompatibility, osseointegration, and durability. The TiO2 nanoparticles were synthesized via the hydrothermal method and extensively characterized for composition, crystallinity, and morphology using techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) with energy dispersive X-ray analysis (EDX), corroborated by elemental mapping. SEM and XRD analyses revealed the synthesized nanoparticles have a spherical shape and an average size of approximately 23 nanometres. The synthesized TiO2 nanoparticles were uniformly coated on SS 316L substrates using the spin coating technique, as confirmed by SEM images. Cell viability of the synthesized TiO2 nanoparticles, as well as uncoated and TiO2 nanoparticle-coated SS 316L substrates, was evaluated using the MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) assay against the NIH-3T3 mouse embryonic fibroblast cell line. The results demonstrated that the TiO2 nanoparticle-coated SS 316L substrate showed a significant increase of 22.87% in cell viability as compared to the uncoated SS 316L substrate. A ball-on-disc tribometer was employed to assess wear and friction resistance at various speeds, viz., 150 rpm, 300 rpm, and 450 rpm, under 30N load conditions for five minutes. The results collectively indicate a substantial improvement in the performance of TiO2 nanoparticle-coated SS 316L substrates for orthopaedic applications.

Villae maritimes, sites ecclésiaux et monastères de l’Antiquité tardive et du haut Moyen Âge
Authors: Bully Sébastien , Čaušević-Bully Morana
Published: July 2024

Composé de plusieurs grandes îles (Krk, Cres, Rab) et de nombreux îlots, l'archipel des Kvarner a joué un rôle stratégique sur les voies de communication transadriatiques nord-sud et est-ouest, tout en constituant un lien important entre la zone adriatique et l'arrière-pays dalmate et, plus largement, avec la Pannonie. Au cours du IIIe siècle, la région semble connaître une nouvelle dynamique grâce à sa position géographique, qui la définit comme une sorte de "seuil" maritime et terrestre de l'Italie antique. De nouveaux établissements maritimes s'installent sur la zone côtière des îles, tandis que les villae du Haut-Empire, établies au début de notre ère, non seulement perdurent mais s'enrichissent. La christianisation de la société dans l'Antiquité tardive se manifeste dans ces villae maritimes du Kvarner par l'apparition de fondations ecclésiastiques privées, également définies sous le terme d'"églises patrimoniales", et dont le phénomène est bien étudié ailleurs. Mais il semble que ce ne soit qu'à l'intérieur des sites majeurs que de nouveaux établissements ecclésiastiques complexes se développent assez tôt, dès le début du Ve siècle. A travers quatre sites de l'archipel du Kvarner, nous interrogerons les différents marqueurs de la détermination des fonctions de ces complexes ecclésiastiques (monastiques ?), mais aussi leur rôle dans la mise en place d'une nouvelle organisation territoriale.
Le peschiere romane: eccezionali testimoni di variazioni di livello marino e di movimenti verticali della crosta terrestre nel mediterraneo
Authors: Anzidei Marco , Benini Alessandra
Published: July 2024

Nell'ambito di progetti multidisciplinari sulle variazioni di
livello marino, nel corso degli ultimi 20 anni sono state esaminate
numerose strutture marittime di epoca romana realizzate lungo le coste
del Mediterraneo come cave, porti, approdi, scivoli di alaggio e
peschiere. In particolare, lo studio si è concentrato sulle peschiere,
le quali hanno fornito i dati più precisi sulle variazioni avvenute
dal momento della loro costruzione, permettendo di individuare il
livello del mare antico con incertezze migliori di ±20 m. Sono state
stimate variazioni di livello marino avvenute negli ultimi
2000±100 anni nei singoli siti studiati, comprese tra +7.5 m e -5 m
circa. In particolare, lungo le coste del Tirreno, dove risiedono la
maggior parte delle peschiere, è stato possibile stimare un valore
medio di aumento di livello marino di 1.22±0.20 m. La variabilità
spaziale dei risultati è coerente con analisi geofisiche, dati
geologici e movimenti tettonici avvenuti nel corso del tardo Olocene
nel Mediterraneo.
Le ville litoranee della Baetica
Authors: Hidalgo Prieto Rafael
Published: July 2024

In questo lavoro presentiamo lo stato dell'arte sulle villae costiere della Baetica. Le villae romane della Baetica sono un fenomeno praticamente limitato alla costa dell'attuale provincia di Malaga.

Végétalité, Art Brut et féminins
Authors: Beuvin Flavie
Published: July 2024

La végétalité est ici pensée comme un phénomène de représentation qui travaille les formes de l’Art Brut. La végétalité s’entend comme modalité d’apparaître d’une multiplicité de féminins et œuvre à l’incarnation des corps créateurs mus par un désir d’existence. Ce concept se déploie dans la diversité de notions et de formes – dimension ornementale, parure, matière, dessin, textile, rhizome – qui rythment les créations textiles de Jeanne Tripier et de Juliette Élisa Bataille, les robes créées par Marguerite Sirvins, Jeanne Laporte-Fromage et Madge Gill et l’œuvre dessinée d’Aloïse Corbaz. La poussée végétale qui bruisse en chacune de ces œuvres nous amène alors à imaginer et rencontrer les corps en situation de création et soumis à la clôture de l’espace asilaire européen au XXe siècle.
