Cloud Crushing and Dissipation of Uniformly Driven Adiabatic Turbulence in Circumgalactic Media
Authors: Lv Alex , Wang Lile , Cen Renyue , Ho Luis C. 
Published: December 2024

Abstract
The circumgalactic medium (CGM) is responsive to kinetic disruptions generated by nearby astrophysical events. In this work, we study the saturation and dissipation of turbulent hydrodynamics within the CGM through an extensive array of 252 numerical simulations with proper cooling mechanisms and a large parameter space spanning average gas density, metallicity, and turbulence driving strength. A dichotomy emerges in the dynamics dissipation behaviors upon turbulence driving turnoff. Hot and subsonic disturbances are characterized by weak compression and slow dissipation, while warm and supersonic turbulences are marked by significant compression shocks and subsequent rapid cooling. In the supersonic cases, the kinetic energy decay is divided into a rate-limiting phase of shock dissipation and a comparatively swift phase of thermal dissipation, predominantly occurring within the overdense regions. Dense clouds are crushed on relatively brief timescales of ∼30–100 Myr, depending on turbulence driving strength but independent from average gas density. This independence is in spite of the complex interplay between the kinetics and thermodynamics of dissipation. The brevity of such timescales relative to typical dynamical timescales within the CGM suggests turbulent clouds must be cotemporal with turbulence driving sources such as cool accretion flows or feedback from the interstellar medium. Quantitative results from this work contribute a novel data set of dissipation timescales that incorporates thermodynamics and radiative cooling in an area of study typically focused on kinematics, which may serve as a valuable asset for forthcoming simulations that aim to explore gas dynamics on galactic and cosmological scales.
Development of Torus and Kink Instabilities in Eruptive Prominences
Authors: Filippov Boris 
Published: December 2024

Abstract
Several filament eruptions with pronounced writhing of the axis of the structure are analyzed. Initially, smooth arches of eruptive filaments are transformed into large-scale helical structures with at least one complete turn due to the development of kink instability. However, the initiation of the eruptions seems to be caused not by the kink instability but by catastrophic loss of equilibrium or torus instability. Calculations of the decay index of the coronal potential magnetic field indicate that the studied filaments began to rise rapidly at heights where the decay index was close to unity, the threshold for the catastrophic loss of equilibrium of straight flux ropes. Although it is often assumed that the kink instability precedes the subsequent torus instability leading to a full eruption, these examples testify to the possibility of the reverse order of the eruption development.

Abstract
The coldest Y spectral type brown dwarfs are similar in mass and temperature to cool and warm (∼200–400 K) giant exoplanets. We can therefore use their atmospheres as proxies for planetary atmospheres, testing our understanding of physics and chemistry for these complex, cool worlds. At these cold temperatures, their atmospheres are cold enough for water clouds to form, and chemical timescales increase, increasing the likelihood of disequilibrium chemistry compared to warmer classes of planets. JWST observations are revolutionizing the characterization of these worlds with high signal-to-noise, moderate-resolution near- and mid-infrared spectra. The spectra have been used to measure the abundances of prominent species, like water, methane, and ammonia; species that trace chemical reactions, like carbon monoxide; and even isotopologues of carbon monoxide and ammonia. Here, we present atmospheric retrieval results using both published fixed-slit (Guaranteed Time Observation program 1230) and new averaged time series observations (GO program 2327) of the coldest known Y dwarf, WISE 0855–0714 (using NIRSpec G395M spectra), which has an effective temperature of ∼264 K. We present a detection of deuterium in an atmosphere outside of the solar system via a relative measurement of deuterated methane (CH3D) and standard methane. From this, we infer the D/H ratio of a substellar object outside the solar system for the first time. We also present a well-constrained part-per-billion abundance of phosphine (PH3). We discuss our interpretation of these results and the implications for brown dwarf and giant exoplanet formation and evolution.
La représentation des tueries de soldats en déroute dans le monde grec (VIe-IVe siècles)
Authors: Laffon Amarande 
Published: December 2024

Une tuerie de soldats en déroute constitue-t-elle une forme de massacre ? L’étude présente les motifs littéraires qui, dans les représentations anciennes des batailles hoplitiques du VIe au IVe siècle av. J.-C., confèrent à certains carnages de soldats en déroute les traits du massacre et paraissent justifier leur intégration dans une typologie des massacres.
Le massacre des Innocents ou comment réécrire l’histoire
Authors: Parmentier Édith 
Published: December 2024

Le « massacre des Innocents », commis par le roi Hérode de Judée, est un événement dont la célébrité tient autant à la fascination exercée par un tel acte de barbarie qu’au rôle fonctionnel joué dans la littérature chrétienne par cet épisode qui fixe la date de naissance de Jésus. L’article montre que ce massacre n’a aucune existence historique. La démonstration procède par une analyse des sources elles-mêmes et par leur contextualisation historique. Sont d’abord étudiées les contradictions et les manipulations textuelles dont l’événement a fait l’objet dans la tradition chrétienne. On envisage ensuite le cadre historique des royaumes hellénistiques du Proche-Orient, dont les pratiques dynastiques brutales ont autorisé la vraisemblance d’un meurtre d’enfants en Judée. Enfin, l’environnement culturel gréco-romain qui a transmis cette fiction dans l’Antiquité en a fait un lieu commun, amalgamant des thématiques d’origines diverses selon le phénomène propre aux légendes noires. Ces mécanismes ont favorisé, à l’époque moderne, le réinvestissement symbolique par la mémoire collective d’un massacre qui n’a jamais eu lieu.
L’identifiant numérique en Inde. Le modèle des fondations d’entreprise
Authors: Belorgey Nicolas 
Published: December 2024

Ce texte porte sur l’identifiant numérique indien, nommé « Aadhaar », qui vise à enregistrer biométriquement l’intégralité de la population indienne, i.e. en 2023 environ 1,43 milliard de personnes. Environ 95 % de cette population, soit 1,36 milliard de personnes, auraient été enrôlées alors dans le dispositif, par ailleurs exporté dans de nombreux pays du Sud et frappant à la porte du Nord. Plus précisément, le rôle des fondations d’entreprise dans la genèse de cet identifiant est ici examiné. Tout d’abord, le texte dépeint leur modèle économique, qui se déploie en trois temps : accumulation initiale par l’entreprise mère, investissements « à but non lucratif » par une ou des fondations, afin de permettre une nouvelle phase d’accumulation. Le texte retrace ensuite les cas de Microsoft, d’Infosys et d’eBay, toutes trois impliquées dans la bataille du déploiement de l’identifiant indien.
La place du paysage et des jardins dans les politiques et projets d’urbanisme à Alger
Authors: Trodi Fares , Donadieu Pierre 
Published: December 2024

À partir des réalisations de la période post-indépendance de l’Algérie (1962-1990), et des impératifs socio-économiques adoptés durant cette même période, l’article analyse la mise en œuvre des politiques publiques de qualité des paysages urbains et des espaces verts à Alger. Il s’appuie sur les discours des urbanistes et sur les projets d’urbanisme, tout en retraçant les moments importants de l’histoire de construction du pays à travers trois périodes (1962-1967 ; 1967-1979 ; 1980-1990). Il explique les résultats modestes obtenus par la priorité politique donnée aux logements et à la mobilité urbaine. L’absence de formation et de recours aux compétences des architectes paysagistes en Algérie est mise en relation avec l’interprétation des projets de paysage urbain.
La pensée de Gorz : un modèle social et politique possible dans et en dehors de l’école à l’ère du changement climatique ?
Authors: Chauvigné Céline 
Published: December 2024

André Gorz (1923-2007) philosophe, grand penseur innovant de la critique de la société capitaliste, fondateur de l’écologie politique propose, par sa approche radicale, des possibles pour défendre « le monde vécu » face à la catastrophe climatique qui sévit depuis les années 1960. En quoi, cette figure avant-gardiste constitue-t-elle une figure inspirante pour la jeunesse aujourd’hui dans et hors l’école pour penser, préserver et imaginer aujourd’hui une vie sur Terre ? Des modèles gorziens aux pratiques juvéniles quelles conditions de possibilité entrevoir pour répondre aux défis contemporains et la vie collective sur Terre ?
John Dewey : la démocratie comme forme de vie et ses implications éducatives.
Authors: Fabre Michel 
Published: December 2024

L’idée de démocratie est un des fils conducteurs de la pensée de Dewey. Elle reçoit chez lui trois significations fondamentales. Elle désigne un régime politique, mais aussi une forme de vie et plus fondamentalement encore, elle se confond avec l’éducation comme auto-contrôle. Comment ces trois sens s’articulent-ils ? Et quelle est l’incidence de ces conceptions sur la démocratie à l’école ? L’hypothèse de Westbroock dans son ouvrage John Dewey and American Democracy (1991) est que Dewey, en quittant l’université de Chicago, se serait détourné progressivement de la réflexion pédagogique sur la démocratie dans l'éducation au profit d’une réflexion politique plus large sur les rapports de la démocratie et de l’éducation. D’où l’impression d’un « chaînon manquant » entre philosophie de l’éducation et réflexion pédagogique concrète. Cet article met à l’épreuve ces hypothèses en confrontant des écrits philosophiques et pédagogiques des Later Works des années 1925-1953 à ceux des Middle Works (surtout ceux des années 1910-1920). Il met en évidence la continuité d’une réflexion philosophique et pédagogique sur la démocratie à l’école, mais qui, dans la dernière période semble en rester au niveau des principes, sans aborder précisément sa mise en œuvre concrète.
Fernand Oury, figure inspirante ou identificatoire ?
Authors: Dubois Arnaud , Canac Frédéric , Geffard Patrick 
Published: December 2024

Les auteurs proposent une réflexion sur la notion de « figure inspirante » et sa pertinence à propos de Fernand Oury, cofondateur de la pédagogie institutionnelle. S’inscrivant dans une approche clinique d’orientation psychanalytique, ils proposent de considérer ce pédagogue davantage comme une « figure identificatoire ». Plutôt que de se focaliser sur une figure individuelle, ils suggèrent que les monographies de la pédagogie institutionnelle sont « inspirantes ». L’analyse d’un texte publié par F. Oury permet de montrer que dès les origines, la pédagogie institutionnelle est porteuse d’une forme de « socialisation démocratique » susceptible de remettre en cause la « forme scolaire ».
Malaria situation in India with special reference to tribal areas
Authors: Sharma Ravendra K. , Thakor H.G. , Saha K.B. , Sonal G.S. , Dhariwal A.C. , Singh Neeru 
Published: December 2024

Background & objectives:
In India, malaria is a major public health problem in States having predominantly tribal population. The objective of this analysis was to find out the incidence of malaria in various States/districts having varied proportions of tribal population using National Vector Borne Disease Control Programme (NVBDCP) data.

Methods:
States and districts were classified into three categories based on proportions of Scheduled Tribes (ST) population as <10, 10-29.9 and 30 per cent + ST population. Five year average (2008-2012) of all important malaria indicators collected by NVBDCP was taken to normalize the effect of annual fluctuations in malaria incidence.

Results:
State level analysis revealed that ten States/UTs with 30 per cent or more tribal population comprising only three per cent of total population, contributed 14 per cent of total malaria, 21 per cent Plasmodium falciparum and 29 per cent of deaths due to malaria. Similarly, district level analysis showed that districts with 30 per cent or more tribal population comprising about eight per cent country's population contributed to 46 per cent of total malaria cases, 70 per cent P. falciparum and 47 per cent malarial deaths in the country.

Interpretation & conclusions:
Our analysis showed that the neglect of the ethnic communities in tribal areas would be detrimental to the overall reduction of morbidity and mortality due to malaria. The fight against the increasing burden of malaria in tribal belt requires adoption of multiple approaches and socio-economic development of the tribal communities.
Health literacy on tuberculosis amongst vulnerable segment of population
Authors: Muniyandi M. , Rao V.G. , Bhat J. , Yadav R. , Sharma R.K. , Bhondeley M.K. 
Published: December 2024

Background & objectives:
Health literacy on tuberculosis (TB) is an understanding about TB to perform activities with regard to prevention, diagnosis and treatment. We undertook a study to assess the health literacy on TB among one of the vulnerable tribal groups (Saharia) in central India.

Methods:
In this cross-sectional study, 2721 individuals aged >15 yr from two districts of Madhya Pradesh State of India were interviewed at their residence during December 2012-July 2013. By using a short-form questionnaire, health literacy on cause, symptoms, mode of transmission, diagnosis, treatment and prevention of TB was assessed.

Results:
Of the 2721 (Gwalior 1381; Shivpuri 1340) individuals interviewed; 76 per cent were aged <45 yr. Living condition was very poor (62% living in huts/katcha houses, 84 per cent with single room, 89 per cent no separate kitchen, 97 per cent used wood/crop as a fuel). Overall literacy rate was 19 per cent, and 22 per cent had >7 members in a house. Of the 2721 respondents participated, 52 per cent had never heard of TB; among them 8 per cent mentioned cough as a symptom, 64 per cent mentioned coughing up blood, and 91 per cent knew that TB diagnosis, and treatment facilities were available in both government and private hospitals. Health literacy score among participants who had heard of TB was <40 per cent among 36 per cent of respondents, 41-60 per cent among 54 per cent and >60 per cent among 8 per cent of respondents.

Interpretation & conclusions:
The finding that nearly half of the respondents had not heard of TB indicated an important gap in education regarding TB in this vulnerable population. There is an urgent need to implement targeted interventions to educate this group for better TB control.
Varied Presentations and Clinical Outcomes of Proliferative Glomerulonephritis with Monoclonal Immunoglobulin Deposit: An Indian Series of Five Patients
Authors: Chakrabarti Uttayan , Chaturvedy Manish , Majumdar Arghya , Bajpai Nitin Kumar , Nalwa Aasma , Das Tapabrata , Agarwal Arpit , Jhorawat Rajesh 
Published: December 2024

ABSTRACT

Background:
Proliferative glomerulonephritis with monoclonal immunoglobulin deposits (PGNMIDs) is a unique and rare entity which can have a variety of presentations ranging from nephrotic syndrome to rapidly progressive renal failure (RPRF). The data about this entity are sparse worldwide and there is hardly any robust literature from India.

Methods:
A retrospective analysis of 320 patients undergoing native kidney biopsy from August 2021 to August 2024 in the Department of Nephrology, AIIMS Jodhpur, was done and 5 cases of PGNMID constituting 1.25% of the native kidney biopsies and 33% of biopsy proven monoclonal gammopathy of renal significance (15 cases) were analyzed.

Results:
The mean age of presentation was 48 years with a female preponderance (80%). The mean estimated glomerular filtration rate at presentation was 34.6 ml/min/1.73 m2 with 60% patients presenting as RPRF, the mean proteinuria being 5.8 g/day. None of the patients had paraproteinemia. On histopathology, membranoproliferative glomerulonephritis was seen in 2 (40%), endocapillary hypercellularity in 2 (40%) and membranous pattern in 1 (20%), with 3 (60%) patients showing crescents. Immunofluorescence showed deposits of immunoglobulin G (IgG) kappa in 4 (80%) and IgG lambda restriction in 1 (20%). Electron microscopy done in 2 of the 5 patients showed subepithelial deposits in one and subendothelial deposits in the other. Therapeutic response was varied. The patient with membranous pattern had an indolent course with just anti-proteinuric measures. Cyclophosphamide–bortezomib–dexamethasone was administered in two patients, being ineffective in both. Rituximab resulted in complete remission in one patient. The outcome in others were unfavorable, 2 (40%) had persistent renal dysfunction while 2 (40%) progressed to end-stage renal disease.

Conclusion:
PGNMID is a distinct entity whose clinical profile may be varied. Chemotherapy has been found to improve outcomes, however, larger prospective randomized multicenter studies are mandated to define the optimal therapeutic approach and duration of treatment.
Faecal microbiota of healthy adults in south India
Authors: Ramadass Balamurugan , Rani B. Sandya , Pugazhendhi Srinivasan , John K.R. , Ramakrishna Balakrishnan S. 
Published: December 2024

Background & objectives:
The relevance of the gut microbiota to human health is increasingly appreciated. The objective of this study was to compare the gut microbiota of a group of adult tribals with that of healthy adult villagers in Tamil Nadu, India.

Methods:
Faeces were collected from 10 healthy tribal adults (TAs) in the Jawadhi hills and from 10 healthy villagers [rural adults (RAs)] in Vellore district, Tamil Nadu. DNA was extracted, and 456 bp segments comprising hypervariable regions 3 and 4 of the 16S rRNA gene were amplified, barcoded and 454 sequenced.

Results:
Totally 227,710 good-quality reads were analyzed. TAs consumed a millets-based diet, ate pork every day, and did not consume milk or milk products. RAs consumed a rice-based diet with meat intake once a week. In both groups, Firmicutes was the most abundant phylum, followed by Proteobacteria, Bacteroidetes and Actinobacteria. The median Firmicutes-to-Bacteroidetes ratio was 34.0 in TA and 92.9 in RA groups. Actinobacteria were significantly low in TA, possibly due to non-consumption of milk. Clostridium constituted the most abundant genus in both groups, but was significantly more abundant in TAs than RAs, while Streptococcus was significantly more abundant in RA (P<0.05). Analyses of genetic distance revealed that the microbiota were distinctly different between TA and RA, and principal component analysis using 550 distinct taxonomically identifiable sequences revealed a clear separation of microbiota composition in the two groups. Phylogenetic analysis of major microbiota indicated clustering of microbial groups at different major branch points for TAs and RAs.

Interpretation & conclusions:
Phylum Firmicutes and genus Clostridium constituted the bulk of the faecal microbiota, while significant differences in composition between the groups were probably due to differences in diet and lifestyle.
Pulmonary Arterial Hemodynamic Assessment by Pulmonary Pulse Transit Time before and after Balloon Mitral Valvuloplasty
Authors: Abdelmordy Abdallah Mohamed Saeed , Serag Amany Ragab Mahmoud , Elkhalek Mohamed Yahia Abd , Zein Fatma Elzahraa Abdelmonem 
Published: December 2024

Background:
Transthoracic echocardiography remains a crucial diagnostic tool for the identification of pulmonary arterial hypertension (PAH). We eagerly await the novel noninvasive techniques development that significantly advances our knowledge of the pulmonary circulation and right ventricle.

Objective:
The objective of this study was to assess pulmonary arterial hemodynamics using pulmonary pulse transit time (pPTT) following balloon mitral valvuloplasty (BMV).

Patients and Methods:
Thirty-three patients with moderate-to-severe mitral stenosis (MS) with varying pulmonary hypertension degree who were presented to the National Heart Institute to do percutaneous mitral balloon valvuloplasty. Participants were evaluated for their echocardiographic variables including the pPTT, and they were followed up immediately, 1 week, 1 month, and 6 months after BMV.

Results:
The study demonstrated a significant and progressive improvement in the right ventricular fractional area change and the tricuspid annular plane systolic excursion (TAPSE) following BMV; on the other hand, the pulmonary artery systolic pressure demonstrated a significant decrease postprocedure and during the follow-up period. On analysis, we found a significant change observed in pPTT values postprocedure (P < 0.001). This value showed a significant reduction immediately following the procedure and the decline continued over the subsequent follow-up periods. Each of these postprocedure measurements showed a significant decrease from the baseline (P < 0.001).

Conclusion:
The pPTT was high in postcapillary pulmonary hypertension (in MS patients) and reduced after correction of causative pathology; the pPTT is a valid measure to assess the improvement in PAH after BMV.
Principles Guiding the Activities of Public Companies in the European Union
Authors: Klimova Tatyana , Shaimerdenova Aigul , Idrysheva Sara 
Published: December 2024

Objective: The article considers the principles of corporate governance in the activities of public corporations in the European Union developed in the late 20th and early 21st centuries.

Methods: The authors traced the chronological development of corporate governance principles, such as information disclosure, operational transparency, shareholder rights equality, and the protection of creditors and other company participants. The analysis included a review of EU legislation and the legal acts of individual countries, such as Ukraine and Russia.

Results: The commonly accepted definition of a public company in dictionaries and regulatory acts is incomplete as it reflects only one characteristic, i.e., the free circulation of shares on the market. According to the new definition, a public corporation is a legal entity with a public nature of operations, obligated to adhere to corporate governance principles. Its supreme governing body is the general meeting of participants, and if securities are issued, they must comply with the stock exchange’s listing requirements.

Originality/Value: The authors offer a thorough chronological analysis of the evolution of these principles, highlighting their role in fostering transparency, safeguarding shareholder rights, and upholding the interests of creditors and other stakeholders. This work’s key contribution is its proposal for a more comprehensive definition of a public company that extends beyond listing shares on the stock market, emphasizing the necessity for public corporations to adhere to corporate governance standards, as outlined in OECD documents. This refined concept presents a valuable framework for strengthening legal systems, particularly in Kazakhstan, by incorporating best practices from the EU and OECD.
