Data-constrained MHD Simulation of a Multi-ribbon Flare Corresponding to a Successful and a Confined Eruption
Authors: Fu Wentai , Guo Yang , Ding Mingde , Zhong Ze , Qiu Ye 
Published: February 2023

Abstract
The formation and eruption mechanisms of multi-ribbon flares are extremely complicated, especially when the flare is associated with homologous eruptions in the same region. In this paper, we investigate such an event, corresponding to a successful eruption and a confined eruption. This is an M7.1 flare, starting at 12:33 UT on 2011 September 24 in active region NOAA 11302. We obtain the coronal magnetic configuration for this region, using a nonlinear force-free field extrapolation based on the photospheric magnetogram at 12:00 UT. Taking this as the initial condition, we perform a data-constrained MHD simulation to study the evolution of the magnetic topology for this region. We analyze the magnetic null points and the 3D squashing degree for this region, indicating the existence of three flux ropes and two spine–fan structures. The model reproduces the rising processes of the two flux ropes, which form two homologous eruptions consistent with the observations as shown in 94 Å: a large-scale successful eruption that is followed by a small-scale confined eruption. By analyzing the magnetic configuration, the Lorentz force, and the decay index, we find that the torus instability plays an important role in driving the successful eruption of the large flux rope. The magnetic reconnection above the medium flux rope changes the direction of the overlying magnetic field, which provides a downward component of the Lorentz force to confine the eruption of the medium flux rope.
Re-evaluation of Cosmogenic 10Be Dating of the Ferromanganese Crust VA13/2 Archiving Interstellar Radionuclides on Earth
Authors: Koll Dominik , Lachner Johannes 
Published: February 2023

Abstract
Interstellar radionuclides, such as 60Fe, are produced in massive stars, ejected by supernovae and can be recovered in geological archives on Earth. Ferromanganese encrustations on the bottom of Earth’s major oceans represent one important geological archive with a time-record of interstellar radionuclides. The paper of Segl et al. provided the first cosmogenic 10Be dating of the ferromanganese crust VA13/2 in which interstellar 60Fe was discovered. After re-evaluation and comparison with other published and recently acquired data of the same crust, we conclude that the calculated 10Be/9Be data set is wrong by a factor of 9 due to a mathematical lapse. In addition, the ordinate of the corresponding 10Be/9Be graph is in discrepancy with the given data. The updated data set is now in agreement with recently published and acquired data.
Que nous apprend la littérature récente sur la « nature et les causes de la richesse des nations » ?
Authors: Combes Jean-Louis , Combes Motel Pascale 
Published: February 2023

Cette revue de la littérature est consacrée aux travaux récents traitant des causes ultimes du développement économique. L’article examine d’abord le rôle moteur joué par les règles du jeu social. Ensuite l’attention se porte sur le rôle des circonstances historiques. Enfin, il s’agit de comprendre comment la géographie peut influencer les trajectoires de développement. Les différentes contributions sont le plus souvent pluridisciplinaires et mobilisent de nouvelles bases de données. Les résultats trouvés dans cette littérature ne doivent pas conduire à penser qu’il existerait un déterminisme culturel, historique ou géographique au développement. C’est dire que les accidents de l’histoire et les décisions de politique économique peuvent aussi provoquer des changements durables dans les trajectoires de développement.

Transforming food and agriculture: Competing visions and major controversies
Authors: Pimbert Michel 
Published: February 2023

Deux modèles de développement opposés cherchent aujourd'hui à transformer radicalement l'alimentation et l'agriculture. Le premier se concentre sur la modernisation et le maintien du capitalisme à travers la promotion de la 4e révolution industrielle (4RI) dans l'alimentation et l'agriculture. La deuxième voie de transformation met l'accent sur la souveraineté alimentaire et l'agroécologie. Cet article met en évidence certaines des principales controverses et défis associés à chacune de ces deux approches de la transformation du système agroalimentaire. Plusieurs des développements les plus contestés dans les domaines écologique, discursif, économique et politique sont identifiés comme des moteurs majeurs de transformation aujourd'hui.

La Economía Social y Solidaria en América Latina y el Caribe Hacia la construcción de economías transformadoras y alternativas
Authors: Berlien Araos Karin , Cediel Morales Hans , Gómez Cuervo María Fernanda , Alvarez Castaño Rubiela 
Published: February 2023

Cet article présente un premier bilan des résultats du « Forum social mondial des économies transformatrices et alternatives en Amérique latine » (en abrégé : FSMET Lac). Il a démarré en 2019, à l’initiative d’institutions latino-américaines (universités, organisations sociales et communautaires, collectifs et réseaux citoyens). Il a donné naissance à des réflexions communes, à partir d’échanges de savoirs, entre les différentes visions, projets et objectifs de solidarité économique dans le sous-continent. Ce processus a permis de reconnaître la diversité des expériences associatives dans le champ économique, leurs points communs, leurs priorités et leurs perspectives, enrichissant la discussion qui a lieu aujourd’hui dans le champ – à la fois théorique et appliqué – de l’économie sociale et solidaire (ESS), avec leurs implications dans les territoires et leurs institutions. Les réflexions théoriques, fondées sur des expériences pratiques, ont montré l’hétérogénéité de l’économie solidaire dans ses réponses à la crise du projet néolibéral qui se manifeste dans la relation du capital au travail et dans la domination du secteur financier sur le secteur productif, ainsi que dans l’aggravation de la santé publique provoquée par le Covid 19. Les points de convergence apparus pendant le FSMET Lac ont été : - Redécouvrir le vieux principe du « bien vivre », ce qui veut dire des économies et des formes d’organisation qui se soutiennent mutuellement dans une éthique relationnelle : entre les personnes, et entre les personnes et la nature. L’écoute, l’observation et l’action respectueuse sont essentielles. - Souligner l’importance de la coordination collective pour répondre aux nécessités productives et reproductives de la vie, en mettant au centre le droit des communautés à un travail qui permette une alimentation saine et la souveraineté alimentaire. - La nécessité de sentir, penser et mettre en place des économies au service de la vie. La méthodologie du dialogue des savoirs a permis d’articuler les apports des 118 intervenantes et intervenants venant de toute l’Amérique latine et des Caraïbes, pendant une cinquantaine de rencontres en ligne. Au-delà de la présentation des alternatives économiques qui se développent, il y a eu des réflexions épistémologiques sur l’importance de l’art dans la représentation et la communication des savoirs, mais aussi comme moyen d’échange, notamment dans des espaces de savoirs et d’actions.
Le rôle du patronat associatif dans l’éclatement conventionnel de la branche sanitaire, sociale et médico-sociale à but non lucratif
Authors: Cottin-Marx Simon 
Published: February 2023

Dans cet article, nous interrogeons le rôle des acteurs « patronaux » dans la production de l’architecture conventionnelle de la branche sanitaire, sociale et médico-sociale à but non lucratif (BASS). La sociohistoire des syndicats d’employeurs que nous réalisons dans ce texte nous permet de comprendre leurs divisions et comment cela a participé à l’éclatement de ce secteur en différentes conventions collectives nationales (CCN) au cours des années 1960 à 1980, avant qu’ils ne s’unissent et créent une branche professionnelle en 1993. Après cette date, les relations entre organisations patronales sont mouvementées, mais elles finissent par converger ces dernières années sur le projet d’une CCN unique et étendue. Suivre ces évolutions nous permet d’observer ce que ce patronat associatif peut faire, mais aussi que l’État reste le principal financeur et régulateur de ce secteur professionnel et qu’il participe activement à la production des règles.
Départementalisation et assimilation : les cinq temps d’une histoire (1982-1946)
Authors: Combeau Yvan 
Published: February 2023

Partant des débats parlementaires de l’automne 1982 sur les propositions du gouvernement de Pierre Mauroy pour la création d’une assemblée unique dans les départements d’Outre-mer, l’article dégage les principaux temps qui ont structuré l’histoire de la départementalisation à La Réunion sur quatre décennies. Le texte analyse la naissance de la loi du 19 mars 1946, les débats autour de cette « décolonisation intra-française », les attentes et les déceptions sur les années de la IV e République et le temps des combats politiques entre départementalistes et autonomistes. Après l’alternance de mai 1981 sont examinées les évolutions institutionnelles proposées par la majorité de gauche et les confrontations politiques jusqu’à la décision du conseil constitutionnel en décembre 1982.
Les projets de départementalisation dans les terres françaises d’Océanie
Authors: Regnault Jean-Marc 
Published: February 2023

Après la Seconde Guerre mondiale, les deux anciennes colonies françaises du Pacifique, la Nouvelle-Calédonie et les Établissements Français d’Océanie deviennent des Territoires d’Outre-mer et gardent leur spécialité législative. Celle-ci permet de préserver les privilèges d’une partie de la population, mais ouvre également la voie à l’autonomie. Pourtant, l’option départementale a été proposée sans succès par les dirigeants de la IV e République et les premiers gouvernements de la V e République. Quant aux élus des territoires, ils oscillent entre les demandes d’élargissement de l’autonomie et le souhait d’une départementalisation dans laquelle ils voient la disparition du système colonial. Après le vote des deux statuts d’autonomie en 1977, la départementalisation n’est plus d’actualité et les revendications portent sur un approfondissement de l’autonomie ou sur l’indépendance.

Les disparus d’Algérie après les accords d’Évian : un angoissant mystère qui s’épaissit entre 1967 et 1992
Authors: Laribi Soraya 
Published: February 2023

Que sont devenus les disparus d’Algérie après les accords d’Évian ? Le secrétaire d’État aux Affaires algériennes, Jean de Broglie, estimait le dossier clos et avait fait distribuer des jugements déclaratifs de décès avant que sa mission ne prenne fin le 8 janvier 1966. Fustigeant la paucité des déclarations et des actions étatiques, l’Association pour la Sauvegarde des Familles et Enfants de Disparus (ASFED) décide de poursuivre les investigations. Elle accompagne plusieurs familles dès 1967 et dresse des listes de disparus, récolte des témoignages, écrit aux parlementaires. Commence néanmoins, à partir des années 1980, une phase de mystification qui décrédibilise sa cause obérant les recherches des (et sur les) disparus.

ABSTRACT

Background:
Neurodevelopmental abnormalities are common in congenital heart disease (CHD), more so in cyanotic CHDs. Perioperative factors have been known to affect neurodevelopmental outcomes.

Aim:
We aimed to determine the neurodevelopmental outcomes following open-heart surgery in cyanotic CHD.

Methods:
In this prospective observational study, eligible infants and children ≤21 months with cyanotic CHD planned for open-heart surgery underwent preoperative neurodevelopmental assessment using Developmental Assessment Scale for Indian Infants (DASII) to look for any motor and/or mental delay. A second neurodevelopmental assessment was performed after 9 months ± 2 weeks of cardiac surgery. Follow-up DASII was conducted through interactive video conferencing in 23 of 60 patients due to COVID-19 pandemic. The univentricular and biventricular repair groups were compared in terms of their neurodevelopmental outcomes. Perioperative factors were compared between neurodevelopmental “delay” and “no delay” groups.

Results:
Of the 89 children enrolled, preoperative motor and mental delay were present in 29 and 24 children, respectively. Follow-up DASII could be performed in 60 children. At follow-up, motor delay was present in seven and mental delay in four children. Overall, there was a significant improvement in both motor and mental developmental quotient at follow-up. There was no significant difference in either motor or mental domains between univentricular and biventricular groups. Among the perioperative variables, only the postoperative length of stay in intensive care unit was significantly different between neurodevelopmental “delay” and “no delay” groups (P = 0.04).

Conclusion:
Neurodevelopmental delay occurred substantially among unoperated children with cyanotic CHD. The neurodevelopmental status improved significantly following open-heart surgery among the survivors. Delay was associated with length of stay in intensive care following cardiac surgery.

Published: February 2023

ABSTRACT

Background:
We evaluated our early experience of cardiac procedures in children with congenital heart defects (CHD) after asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, to understand whether recent reverse transcription-polymerase chain reaction (RT-PCR) positivity had a negative impact on their postprocedural recovery and outcomes.

Materials and Methods:
In this retrospective observational study, all patients with CHD who underwent cardiac surgery or transcatheter intervention at our institution between March 2020 and June 2021 who were detected to have asymptomatic SARS-CoV-2 infection on routine RT-PCR were included. Details of the cardiac procedure and postprocedural recovery were reviewed and compared with RT-PCR-negative patients who concurrently underwent similar cardiac surgeries or interventions at our center.

Results:
Thirteen patients underwent cardiac surgery after recent SARS-CoV-2 positivity after a mean interval of 25.4 ± 12.9 days. One patient expired with multiorgan dysfunction and systemic inflammatory response with elevated D-dimer, serum Ferritin, C-reactive protein, and significant ground-glass opacities on chest radiograph. Another patient developed spontaneous thrombosis of the infrarenal abdominal aorta, bilateral iliac arteries, and bilateral femoral veins, requiring low-molecular weight heparin postoperatively. This patient's postoperative recovery was also prolonged due to lung changes delaying extubation. All other patients had uneventful postprocedural recovery with intensive care unit and hospital stays comparable to non-SARS-CoV-2-infected patients.

Conclusions:
From our early experience, we can surmise that an interval of 2–3 weeks after asymptomatic SARS-CoV-2 infection is adequate to undertake elective or semi-elective pediatric cardiac surgeries. For patients requiring emergent cardiac surgery prior to this interval, there is potentially increased risk of inflammatory and/or thrombotic complications.

Published: February 2023

ABSTRACT
Congenital JET (junctional ectopic tachycardia) is a rare and often difficult to treat tachyarrhythmia in young infants. The addition of Ivabradine to standard Congenital JET therapy has been shown to improve arrhythmia control. However, Ivabradine has not been reported as a single drug in the control of congenital JET. We report a pre-term neonate in whom Ivabradine monotherapy was successful in treating congenital JET.
Scimitar syndrome and left pulmonary vein stenosis
Authors: Mendoza Alberto , Herrera Dolores , Caro Ana T. , García Enrique , Montañés Elena , Granados Miguel Angel 
Published: February 2023

ABSTRACT
Scimitar syndrome is a rare constellation of cardiovascular anomalies consisting of partial right anomalous pulmonary venous drainage to the inferior vena cava, hypoplasia of the right lung, cardiac dextroposition, and in many cases, one or more aortopulmonary collaterals from the descending aorta to the hypoplastic lung. The “infantile form” commonly presents with significant heart failure and pulmonary hypertension. Stenosis of the left pulmonary veins associated with scimitar syndrome is a rare but well-described combination, usually associated with a poor prognosis. We describe two patients with this association in whom the left pulmonary vein stenosis manifested months after the initial diagnosis as a progressive lesion that complicated the course of the disease due to severe pulmonary hypertension. Both patients were successfully treated with a combination of surgical, percutaneous, and hybrid treatment.

Authors: Sammartano Antonino , Migliari Silvia , Serreli Giulio , Scarlattei Maura , Baldari Giorgio , Ruffini Livia 
Published: February 2023

Purpose of the Study:
Ga-68-DOTA-peptides targeting somatostatin receptors have been assessed as a valuable tool in neuroendocrine tumors imaging using positron emission tomography (PET). A new selective and sensitive high-pressure liquid chromatography (HPLC) method was developed for determining chemical and radiochemical purity of Ga-68-DOTATATE (PET) tracer. The identification of peaks was achieved on a symmetry C18 column 3 μm 120Å (3.0 mm × 150 mm spherical particles) using (A) water + 0.1% trifluoroacetic acid (TFA) and (B) acetonitrile + 0.1% TFA, as the mobile phases at a flow rate of 0.600 mL/min and monitored at 220 nm. The run time was 16 min.

Materials and Methods:
The method was validated to fulfill International Conference on Harmonization requirements and EDQM guidelines, and it included specificity, linearity, limit of detection (LOD), limit of quantification (LOQ), accuracy, and precision.

Results:
The calibration curve was linear over the concentration range from 0.5 to 3 μg/ml, with a correlation coefficient (r2) equal to 0.999, average coefficient of variation (CV%) 2%, and average bias% did not deviate more than 5% for all concentrations. The LOD and LOQ for DOTATATE were 0.5 and 0.1 μg/mL, respectively. The method was considered precise, obtaining coefficients of variation between 0.22% and 0.52% for intraday and 0.20% and 0.61% for interday precision. Accuracy of method was confirmed with average bias% that did not deviate more than 5% for all concentrations.

Conclusion:
All results were acceptable and this confirmed that the method is suitable for its intended use in routine quality control of Ga-68-DOTATATE to guarantee the high quality of the finished product before release.

Authors: Tyagi Nitesh , Patil Neelkant , Sareen Mohit , Meena Manoj , Rathore Supriya , Kaswan Shobhit 
Published: February 2023

Background:
Cone beam computed tomography (CBCT) is a diagnostic imaging modality for implant and surgical procedures in anterior and posterior mandibular area. It provides adequate information concerning maxillofacial regions, optimum image quality, excellent geometric accuracy, and low radiation dose.

Aim:
The aim of this study was to evaluate prevalence and anatomical variations in Mandible (Mandibular Incisive canal, Lingual Foramen, Mental Foramen, and Mandibular canal) in CBCT scans of the maxillofacial region.

Methodology:
All CBCT cross-sectional images of 40 study participants was analyzed for the presence of anatomical landmarks. All the anatomical parameters were compared with respect to age groups, dentition, gender, and right and left side and their respective distances from the inferior border of mandible and alveolar crest were measured using CS 3D imaging software (Kodak).

Results:
Lingual Foramen, Mental Foramen, and Mandibular Foramen were seen in all (100%) study samples, incisive foramen 83% and anterior loop in 25% of study samples. On statistical analysis, the difference of the mean distance of incisive foramen, mental foramen, anterior loop and mandibular foramen from lower border of mandible and alveolar crest was significant with relation to gender (P = 0.006) and with relation to dentate, partially dentate, and edentulous were found to be significantly different (P < 0.001).

Conclusions:
Careful assessment of the anatomical landmarks is essential to avoid neurosensory and bleeding complications using CBCT.
