Discovery of RR Lyrae in the Ultra-faint-dwarf Galaxy Virgo III
Authors: Ngeow Chow-Choong , Bhardwaj Anupam
Published: June 2024

Virgo III is a newly discovered ultra-faint-dwarf (UFD) candidate, and finding RR Lyrae associated with this galaxy is important to constrain its distance. In this work, we present a search of RR Lyrae in the vicinity of Virgo III based on the time-series r-band images taken from the Lulin One-meter Telescope (LOT). We have identified three RR Lyrae from our LOT data, including two fundamental mode (ab-type) and a first-overtone (c-type) RR Lyrae. Assuming these three RR Lyrae are members of Virgo III, we derived the distance to this UFD as 154 ± 25 kpc, fully consistent with the independent measurements given in the literature. We have also revisited the relation between absolute V-band magnitude (M

V
) and the number of RR Lyrae (of all types, N
RRL) found in local galaxies, demonstrating that the M

V
-N
RRL relation is better described with the specific RR Lyrae frequency.
An Explainable Deep-learning Model of Proton Auroras on Mars
Authors: Dhuri Dattaraj B. , Atri Dimitra , AlHantoobi Ahmed
Published: June 2024

Proton auroras are widely observed on the dayside of Mars, identified as a significant intensity enhancement in the hydrogen Lyα (121.6 nm) emission at altitudes of ∼110 and 150 km. Solar wind protons penetrating as energetic neutral atoms into Mars’ thermosphere are thought to be primarily responsible for these auroras. Recent observations of spatially localized “patchy” proton auroras suggest a possible direct deposition of protons into Mars’ atmosphere during unstable solar wind conditions. Improving our understanding of proton auroras is therefore important for characterizing the interaction of the solar wind with Mars’ atmosphere. Here, we develop a first purely data-driven model of proton auroras using Mars Atmosphere and Volatile Evolution (MAVEN) in situ observations and limb scans of Lyα emissions between 2014 and 2022. We train an artificial neural network that reproduces individual Lyα intensities and relative Lyα peak intensity enhancements with Pearson correlations of ∼94% and ∼60% respectively for the test data, along with a faithful reconstruction of the shape of the observed altitude profiles of Lyα emission. By performing a Shapley Additive Explanations (SHAP) analysis, we find that solar zenith angle, solar longitude, CO2 atmosphere variability, solar wind speed, and temperature are the most important features for the modeled Lyα peak intensity enhancements. Additionally, we find that the modeled peak intensity enhancements are high for early local-time hours, particularly near polar latitudes, and the induced magnetic fields are weaker. Through SHAP analysis, we also identify the influence of biases in the training data and interdependences between the measurements used for the modeling, and an improvement of those aspects can significantly improve the performance and applicability of the ANN model.
Dynamic Single-Leg Balance Tests of Physiotherapy Students: A Comparison of Body-Active Weight Shift Test and Two Sudden Disturbance Tests
Authors: Tivadar Blanka Koščak , Kotnik Petra
Published: June 2024

BACKGROUND: Balance is essential to maintain and stabilize the transition from static to dynamic posture. The human body can maintain the center of gravity within the base of support and to process input from vision, the vestibular apparatus, and the somatic senses.
AIM: The research aimed to check the correlation of the active body-weight shift test (Y balance test [YBT]) and two sudden perturbation tests in physiotherapy students.
METHODS: In a cross-sectional study, a descriptive research design was used. Twenty-nine healthy adults (14 men and 15 women) with a mean age of 23.6 ± 6.3 were tested using the active body-weight shift test and two sudden perturbation tests. A descriptive statistical analysis using correlation coefficients was performed.
RESULTS: Our subjects’ average values of the test results meet the normative values. There is a correlation between the YBT test and the crossover hop test in the anterior (p < 0.01), posterior-medial, and posterior-lateral directions (p < 0.05), and the triple-hop test forward in the posterior-medial and posterior-lateral directions (p < 0.05), and anterior direction (p < 0.01) for the left extremity, except for the anterior direction to the right. With the right extremity, there is a correlation between the YBT test and the crossover hop test and triple-hop test forward in the posterior medial (p < 0.05), the crossover hop test in the posterior medial and posterior lateral to the left (p < 0.05), and the right (p < 0.01), but no correlation in the anterior direction in either of them.
CONCLUSION: The data of all physiotherapy students in our study meet the normative data, and no difference due to gender has been observed. There is a correlation between the active body-weight shift test and sudden perturbation tests with or without lateral movement for the left extremity, but not for the right extremity. We can assume better results when standing on an undominant limb, which can lead to insufficient support when standing on a dominant limb. What should not be the case in providing patient safety.
Systematic revision and molecular phylogenetics refine the generic classification of the bark louse family Stenopsocidae (Insecta: Psocodea: Psocomorpha)
Authors: Liang Feiyang , Liu Xingyue
Published: June 2024

Psocomorpha, as one of the suborders of the order Psocodea, represents a large group of free-living bark lice. The phylogenetic relationships among/within the major groups, such as families, subfamilies, tribes, etc., of the bark lice need extensive investigation. The family Stenopsocidae belongs to the infraorder Caeciliusetae, which is a large group of Psocomorpha and is one of the common groups in Asia. Here we infer the intergeneric relationships of Stenopsocidae based on the mitochondrial genes and the nuclear 18S rRNA. The result supports the monophyly of Stenopsocidae and suggests the paraphyly of the genus Stenopsocus. Combining the morphological evidence, we propose a new genus, namely Neostenopsocusgen. n., which includes a number of species previously placed in Stenopsocus. The checklist of this new genus is provided. This new genus can be distinguished from Stenopsocus by the glabrous forewing CuP. In the revised classification system, Stenopsocidae includes four genera: Graphopsocus, Malostenopsocus, Neostenopsocusgen. n., and Stenopsocus. A key to the genera of Stenopsocidae is provided. We also present the diagnostic characters for each of these genera.

La improvisación de la «ira sagrada» del ’36. Un enfoque microhistórico
Authors: López Villaverde Ángel Luis
Published: June 2024

Il conflitto politico e religioso degli anni Trenta in Spagna, non può essere compreso solo dalle relazioni Chiesa-Stato, dai discorsi parlamentari, dalle manifestazioni violente o dalla legislazione anticlericale. Quando viene affrontata la pressione esercitata dalle basi anticlericali, la lotta identitaria e delle pratiche simboliche, la secolarizzazione dello spazio pubblico o la visione più territoriale, appare in tutta la sua complessità. Se dirigiamo la nostra attenzione all’analisi della violenza anticlericale del quinquennio repubblicano, troveremo, fondamentalmente, una risposta chiara contro il potere, ma non una vera e propria «persecuzione religiosa». Niente a che vedere con ciò che accadde a partire dal 18 luglio 1936, quando ci fu una svolta importante. Da quel momento, la questione religiosa assunse quindi un ruolo centrale nella reazione di una strategia propagandistica del bando ribelle (la chiamata “crociata” o cruzada), ma anche della «ira sagrada» che costituì l’incipit della violenza rivoluzionaria. In queste pagine, si tratta quindi di confermare, a partire da un quadro micro-storico, quale fu la svolta nella violenza anticlericale, ma di osservare anche come nell’estate del 1936, si improvvisò un repertorio iconoclasta e prossimo alla clerofobia, vincolato a quelle zone della retroguardia repubblicana prive di precedenti violenti e che non avevano facilitato l’avvio del processo rivoluzionario.
La mirada americana. Estados Unidos y el factor católico en la España de la II República
Authors: Rodríguez Lago José Ramón
Published: June 2024

La Seconda Repubblica attrasse l’attenzione degli Statunitensi, fossero cattolici o meno, che volevano confermare il successo di una nuova democrazia in un paese di radicata tradizione cattolica. La corrispondenza e i documenti redatti da William Montavon per la National Catholic Welfare Conference, o dagli ambasciatori nordamericani a Madrid Irwin Laughlin y Claude Bowers, per il Dipartimento di Stato permettono di analizzare le diverse immagini e la riflessione generata dall’evoluzione del fattore cattolico nella volubile congiuntura repubblicana. Constatano pure l’influenza emergente delle reti transnazionali tessute dalla Corporazione vaticana nel contesto spagnolo.
Secularización, sexualidad y estereotipos de género a través del divorcio republicano: Valladolid, 1931-1937
Authors: Serrano García Rafael
Published: June 2024

Il divorzio si stabilì per la prima volta in Spagna nel 1932, dentro un insieme di misure che perseguivano la secolarizzazione della società e il rafforzamento dei diritti dei cittadini concentrandosi sulle donne e sulla famiglia. In questo articolo ci riproponiamo di analizzare l’applicazione della legge in un ambito concreto: la provincia di Valladolid, di cui analizzeremo le domande di divorzio che si presentarono tra il 1932 e il 1937, per vedere fino a che punto emergono, nelle relazioni di coppia, le differenze di carattere religioso, o pratiche eterodosse in ambito sessuale. Infine indagheremo i modelli di genere principalmente femminili costruiti dagli avvocati nelle loro domande.

De la spécificité des disciplines aux pratiques enseignantes et à la formation : quelques réflexions pour les mathématiques et les sciences
Authors: Munier Valérie , Proulx Jérôme
Published: June 2024

This article addresses questions relative to teachers of mathematics and sciences. We first establish the notion of the specificity of both disciplines as an epistemological background to underpin our ways of tackling questions about teachers’ practices, knowledge and training initiatives. Addressing issues about practices (of teachers and of teacher education) in relation to each disciplines’ specificity invites taking into account the nature of scientific and mathematical activity in itself. These orientations lead to consider the possibilities, in contrast to prescriptions, for adressing issues of teachers’ knowledge and practices, and their implications for teacher education practices.

Michael Stolleis und Sten Gagnér
Authors: Haferkamp Hans-Peter
Published: June 2024

Die Studie deutet die in diesem Heft zu diskutierenden methodologischen Prämissen von Michael Stolleis als stark von seinem Münchener Lehrer Sten Gagnér geprägt. Gagnér entwickelte in den 1960er Jahren in Auseinandersetzung mit dem skandinavischen Rechtsrealismus und den Philosophischen Untersuchungen von Ludwig Wittgenstein ein rechtshistorisches Methodenprogramm, das die Rekonstruktion von Sprachspielen unter Einbeziehung des Sprachkontexts in den Mittelpunkt rückte. Damit hing eine Kritik an der zeitgenössischen deutschen Rechtshistoriografie zusammen, der Gagnér Metaphysik vorwarf. Stolleis nahm dieses Denken im Münchener Seminar von Gagnér auf und blieb diesen Grundüberzeugungen lebenslang treu.

La propriété et les propriétés dans l’officine de l’historien
Authors: Grossi Paolo
Published: June 2024

Prenant son point de départ dans un titre d’un rapport du civiliste Pugliatti sur la propriété et les propriétés, l’article propose avec l’emploi du pluriel de relativiser la conception absolutiste de la propriété qui a triomphé au xixe siècle. L’expérience médiévale est celle d’un autre rapport de l’homme aux choses, fondé sur la possession et l’exploitation de la terre, et conduisant à envisager une pluralité de propriétés sur le même bien. Apparue au Haut Moyen Âge cette superposition de propriétés a été théorisée, avec la redécouverte des compilations de Justinien, à travers la notion de domaine utile et la théorie du domaine divisé. Bien que reposant sur une contradiction dans les termes mêmes de dominium utile, cette construction des juristes s’est ancrée dans les mentalités pendant des siècles. Trouvant ses origines dans les réflexions des théologiens et des philosophes depuis le xive siècle, la nouvelle conception anthropologique du rapport du sujet aux choses a donné naissance à l’individualisme possessif et à la propriété ‘moderne’.
Un droit sans État
Authors: Grossi Paolo
Published: June 2024

Ce texte de Paolo Grossi invite les spécialistes d’histoire du droit du Moyen Âge à se débarrasser de deux notions qu’il considère comme « encombrantes » et profondément étrangères à l’expérience juridique médiévale, à savoir les notions de « souveraineté » et d’« État ». Pour cela, Grossi oppose un modèle unitaire moderne, où l’État souverain est la seule instance légitime à légiférer et à façonner le juridique, à un modèle pluraliste médiéval caractérisé par une grande variété de sources, d’instances et de communautés autorisées à produire du droit. Grossi met en avant l’intérêt analytique de la notion d’« autonomie » pour comprendre la pluralité des ordres juridiques du Moyen Âge ; il en ressort l’idée d’un « droit sans État », fondamentalement arrimé au monde social et qui l’exprime dans toutes ses dimensions. L’article propose ainsi une relecture radicale de la pensée politique et juridique médiévale.
Pluralité des sources et actuation de la Constitution
Authors: Grossi Paolo
Published: June 2024

Dans ce texte – version écrite d’une leçon tenue en 2019 à l’École Nationale de Magistrature italienne – Paolo Grossi s’interroge d’abord sur la « juridicité » de la Constitution ainsi que sur les rapports entre République et État, soulignant l’âme multi-ordonnant de la Constitution italienne. Paolo Grossi invite à prendre conscience que vivre, aujourd’hui, la dimension constitutionnelle de la République signifie respecter le pluralisme juridique qui lui est propre. C’est pour cela que Paolo Grossi prône le passage « de la loi à l’interprétation », possible aussi grâce au secours épistémologique de celle que l’auteur appelle la « révolution herméneutique ». Il s’interroge enfin sur deux questions fondamentales dans cette perspective : quoi faire de la « soumission du juge à la loi » ? Et de la prétendue séparation des pouvoirs ?
Escrituras en escena: Teresa de la Parra y el teatro de lo íntimo
Authors: Bouzaglo Nathalie
Published: June 2024

Este artículo analiza los modos en los que la escritora venezolana Teresa de la Parra escenifica su propio lugar dentro del mundo literario, frente a las fronteras y potencialidades de género y nacionalidad de su tiempo. Se examina el lugar del seudónimo en su producción, así como el rol icónico que ocupó Sarah Bernhardt y el mundo de lo exótico como influencias claves en su escritura. La excentricidad se conecta con la crítica hacia el estado de la cultura en Venezuela, en contraste con la proyección internacional alcanzada por de la Parra. La escritora se enfrenta a las limitaciones en torno a la vanidad y frivolidad que define la recepción de Ifigenia en Venezuela. Sin embargo, Teresa de La Parra propone pensar lo nacional en términos de un proyecto hispanoamericano. El ensayo muestra cómo Teresa de la Parra participa estratégicamente en las políticas editoriales de la ciudad letrada, y logra ser una mujer famosa en una época en que la fama no era fácil de obtener para una latinoamericana de principios de siglo XX.

Este ensayo analiza cinco textos -un cuento y cuatro ensayos- de la escritora dominicana Abigail Mejía que contribuyen a los debates políticos que se dieron durante la Invasión de Estados Unidos a la República Dominicana (1916-1924) y que fueron publicados en diarios españoles (La Vanguardia y Hojas Selectas) y dominicanos (La Conquista) entre 1918 y 1921. Este ensayo lee estos artículos en clave afectiva para analizar cómo la autora genera un capital afectivo y cómo gestiona los afectos producidos por la invasión americana.
L’accès à la formation des salariés en emplois non qualifiés : s’il suffisait d’aspirer !
Authors: Béduwé Catherine , Akremi Assâad El , Stephanus Camille
Published: June 2024

Dans le contexte des réformes engagées depuis le début des années 2000, avec un objectif de responsabilisation des individus quant à leur parcours professionnel, de nouveaux droits individuels ont été attribués aux salariés, sensés leur permettre un recours plus autonome à la formation. Toutefois, dans la lignée de la notion d’appétence et en mobilisant les données du dispositif DEFIS (Dispositif d’enquêtes sur les formations et les itinéraires des salariés), cette étude interroge l’effet de levier de l’aspiration à se former sur l’accès à la formation des salariés en emplois non qualifiés. Nos modèles d’analyse révèlent que l’aspiration a un effet significatif de déverrouillage du processus d’action dans la formation. Lorsque cet effet est croisé avec des facteurs organisationnels tels que les entretiens professionnels et l’accès à l’information, l’accès à la formation est davantage renforcé pour l’ensemble des salariés. Toutefois, en dépit des effets positifs de la combinaison de ces facteurs, les inégalités entre les salariés en emplois qualifiés et ceux en emplois non qualifiés persistent et demeurent significatives.
Pourquoi former des « non-qualifiés » ? Le cas des agents d’entretien et des aides à domicile
Authors: Burie Adèle , Devetter François-Xavier , Valentin Julie
Published: June 2024

Les métiers dont une fraction de l’activité relève du nettoyage constituent une part importante des métiers considérés comme peu qualifiés. Pourtant, bien que rares, des politiques en termes de formation professionnelle sont mises en œuvre. Cet article se centre sur les agents d’entretien et les aides à domicile pour dresser un bilan du rapport à la formation dans ces secteurs, d’un point de vue quantitatif et qualitatif. Il propose une analyse des motivations avancées par les employeurs, en distinguant les logiques de préparation des salariés à l’emploi et celles, plus ambitieuses, qui permettent de repenser le travail et les parcours professionnels. Il révèle les conditions requises pour que se déploie cette seconde approche de la formation : la reconnaissance sociale des compétences mobilisées et l’identification d’un employeur qui assume ses fonctions.
Panorama de la non-qualification : un manque de perspectives professionnelles quand le travail est peu qualifié
Authors: Lambert Marion , Marion-Vernoux Isabelle
Published: June 2024

Ce travail statistique met au jour la diversité des formes de non-qualification, combinaison des caractéristiques des personnes, de leur emploi et du travail qu’elles exercent. Le troisième registre, celui du travail, caractérise à la fois le contenu de celui-ci et les conditions dans lesquelles il s’exerce. L’article présente une méthodologie pour en délimiter le périmètre à la croisée des caractéristiques des contextes organisationnels et des activités de travail des salariés. La prise en compte de cette dimension permet de montrer que bien que diplômés et mieux rémunérés, 14 % des salariés se trouvent dans une situation de non-qualification « masquée ». En effet, cette catégorie de salariés peu ciblée par les politiques publiques, évolue pourtant dans un contexte peu propice au développement des apprentissages ne permettant pas de satisfaire leurs besoins en compétences pour évoluer favorablement sur le marché du travail.
Quand l’humanitaire reproduit de profondes inégalités de carrière
Authors: Mba Jean Émile , Keuya Éveline , Beaulieu Janyck
Published: June 2024

Cet article aborde la question des inégalités de carrière des agent·es d’entretien qui occupent une position peu qualifiée au sein des organisations humanitaires internationales au Cameroun. Il soulève une problématique novatrice qui s’intéresse à l’analyse de ces inégalités dans un champ qui pourtant prône l’égalité, l’équité et le développement humain. Mobilisant des théories éthiques du care et de la segmentation du marché du travail, il montre comment ces agent·es, en particulier les femmes, sont victimes de fortes inégalités de carrière, à la fois en raison des normes genrées associées au travail de soin, ainsi que du caractère hybride de leur métier : entre un travail domestique et un service d’entretien des bureaux. Cette hybridation s’accompagne de limitations d’accès à la formation et à la mobilité professionnelle, elles-mêmes adossées au faible niveau d’éducation de ce personnel d’entretien dans un secteur humanitaire devenu très professionnalisé.
Strip Casting of Al-25%Si-4%Mg Using Unequal Diameter Twin Roll Caster Equipped with Steel Rolls
Authors: Haga Toshio , Ochi Hiizu , Fuse Hiroshi , Watari Hisaki , Nishida Shinichi
Published: June 2024

Strip casting of Al–25%Si was tested using an unequal-diameter twin-roll caster equipped with steel rolls. To increase the cooling ability, the shell thickness was decreased to 6 mm. The solidification length was 180 mm to solidify Al–25%Si, which has large latent heat. 4% Mg was added to Al–25%Si to prevent the strip sticking to the roll without using parting material. A grooved roll was adopted for the upper roll to prevent solidification shrinkage and strip cracking during rolling. Al–25%Si–4%Mg strip could be cast at a roll speed of 10 m/min by these enhancements. The as-cast strip could be hot rolled down to 1 mm. A cross section of the strip was investigated using optical microscopy, and the primary Si and eutectic Si were found to be very fine.
Impacts of Lithium Salt on Interfacial Reactions between SiO and Ethlyene Carbonate-Based Solutions in Lithium Secondary Batteries
Authors: Yoon Sungjae , Lee Sangyup , Nogales Paul Maldonado , Jeong Soon Ki
Published: June 2024

This study investigates the influence of lithium salt on the interfacial reactions that occur between SiO and ethylene carbonate-based solutions in lithium secondary batteries. Electrochemical reactions occurring at a SiO electrode were examined to gain insights into the effects of lithium salts, such as LiPF6, LiBF4, LiClO4, and LiCF3SO3, on the interfacial resistance. The SiO electrode exhibited a relatively high reversible capacity and Coulomb efficiency in an electrolyte solution containing LiCF3SO3. The interfacial resistance was the highest in the solution containing LiPF6 and the lowest in the solution containing LiBF4. The findings from this investigation are expected to offer valuable insights for optimizing the design and performance of lithium secondary batteries by manipulating interfacial reactions.

Inadequate handling and disposal of contaminated industrial waste significantly contribute to environmental pollution. The presence of pollutants, including dyes, in wastewater necessitates the development of innovative remediation techniques. Metal oxide-catalyzed photodegradation capitalizes on the capacity of a dye to absorb light energy, offering a rapid method to break down the dye into less harmful, colorless byproducts. In this work, bimetallic copper-iron oxides with various copper to iron were synthesized for the photodegradation of fuchsine. The photocatalysts were prepared through oxalate precipitation followed by thermal decomposition. Structural analysis revealed a MOF-like structure of the bimetallic oxalate precursors. Thermal decomposition of the oxalates yielded photocatalytic bimetallic copper-iron oxides. Photodegradation studies demonstrated that the addition of copper-iron oxides accelerated the degradation of fuchsine and a higher concentration of CuO enhances the performance of the photocatalyst. Notably, the copper-iron oxide with a 1:1 (CuFe) ratio proved to be the most effective catalyst for the photodegradation of fuchsine. Furthermore, the photodegradation of fuchsine conforms to a pseudo-first order model and exhibits characteristics of a first-order reaction. Our findings emphasize that simple and high-efficiency bimetallic oxide catalysts can be used for water decontamination applications.
Bilateral Persistent Sciatic Artery – An Infrequent Occurrence: A Case Report with Review of Literature
Authors: Nirhale Dakshayani Satish , Ramya Vajja , Wante Mahendra , Premchand Kalari , Burra Anoop , Bandla Vijetha , Arigela Abhinav
Published: June 2024

A persistent sciatic artery (PSA) is a rare congenital vascular anomaly with an extremely low incidence of about 0.04%–0.06%. It is due to the persistence of the embryological axial limb artery, representing a continuation of the internal iliac artery into the thigh through the greater sciatic foramen below the piriformis muscle and down the thigh alongside the sciatic nerve. In normal embryologic development of the lower limb, the axial artery normally regresses after week 12. Persistent sciatic artery is often asymptomatic until a complication develops, it can be classified into two types, complete and incomplete. PSA can cause serious lower limb complications such as acute or critical limb ischemia.

Published: June 2024

Background:

Understanding the impact of malnutrition on innate immune response in Plasmodium falciparum (Pf)-infected subjects is critical for malaria control.

Aims and Objectives:

This study aims to investigate the nutritional status and innate immune response of Pf-infected subjects in Lagos, Nigeria.

Materials and Methods:

A total of 1183 patients with a history of fever or axillary temperature ≥37°C were screened microscopically for Pf at Ijede General Hospital, Lagos, Nigeria. Malnutrition was determined according to the U.S National Center for Health Statistics (NCHS) as stunting, wasting, or underweight when the Z-score is <−2 in the participants aged <20 years. Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and IL-12 were determined by capture ELISA while hematological parameters were measured using an automated hematology system.

Results:

A total of 384 volunteers were positive for Pf, of which 114 were <20 years with a median age of 10 years. Overall malaria prevalence was 20.89%. The malnutrition rate was 89.5%; 24 (21.05%) were stunted, 30 (26.32%) were underweight, and 48 (42.11%) were wasted. Pro-inflammatory cytokine responses were not affected by the type of malaria. TNF-α was higher in participants <5 years (P = 0.001) and in malnourished patients (P < 0.05).

Conclusion:

Together, it could be deduced that nutritional status influences Plasmodium falciparum malaria outcomes and progression pattern.
Unraveling the Enigma of Dental Caries through Conventional Analysis using Finger Print Forensics among the Students of Nadiad City, Gujarat
Authors: Mehta Rina Girish , Patel Bhupesh , Kamlesh B Rami , Patel Hiren
Published: June 2024

Introduction:

There is growing interest in identifying genetic predispositions to dental caries using non-invasive tools. Dermatoglyphics, examining dermal ridge patterns on the hands and feet, is linked to genetic foundations. Galton’s theory asserts fingerprint constancy. In dentistry, dermatoglyphics gains attention for its correlation with students pathologies. This study evaluates the association of dental caries in students with dermatoglyphics.

Materials and Methods:

The research at the Department of Oral and Maxillofacial Pathology, Dharmsinh Desai University, involved 50 subjects (28 females and 22 males) with normal fingerprints. Ethical clearance was obtained from the institute’s Ethics Committee. Fingerprints were recorded using the conventional method, employing ink, paper, roller, glass slab and sponging pad. The prints were examined, classified and analysed through the Cummins method, categorising them into whorls, loops and arches. The dental caries were assessed through the decayed, missing and filled teeth (DMFT) scores of the participants. The DMFT score was tested for association and difference according to the type of fingerprint pattern.

Results:

Females commonly exhibit loop patterns, while males show an equal distribution between loops and whorls. The connection between fingerprint patterns and DMFT scores is notable. A Chi-square test for left-side patterns (Chi-square = 27.74, P = 0.002) reveals a strong association, linking specific patterns to distinct DMFT scores. Similarly, for right-side patterns (Chi-square = 11.349, P = 0.045), there is significance, emphasising the relationship between fingerprint types and dental caries.

Conclusion:

The study examined the connection between fingerprint patterns and dental caries in children, discovering a positive correlation. Specific patterns such as arch, loop and whorl were linked to caries presence or absence, suggesting their potential as an early detection tool, although accuracy might vary based on genetic factors.
Dental Erosive Wear Assessment amongst Different Age Groups Utilising Basic Erosive Wear Examination: An Epidemiological Study
Authors: Verma Anirudh , Prasad D Krishna
Published: June 2024

Introduction:

The study aims to assess the prevalence of erosive tooth wear and risk levels amongst different age groups utilising Basic Erosive Wear Examination (BEWE) amongst the population of South West Coastal India.

Materials and Methods:

One hundred and sixty healthy people participated in the research (n = 32 per group). Using sextants and the BEWE, index (0–18) allowed for the evaluation of erosive tooth wear. Questionnaires supplemented clinical data. Each participant was assigned to groups based on the severity of their erosive wear: high (BEWE sum ≥ 14), moderate (BEWE sum 9–13), low (3–8) and none (0–2).

Results:

There is no significant difference in the degree of erosive tooth wear across different age groups (χ2– 20.11, P – 0.067 [not-significant]). There is a significant difference in response to questions across different age groups (χ2 – 487.21, P – 0.01 [significant]).

Conclusion:

The prevalence of erosive tooth wear grows as individuals age. Older age groups, patients who are at a higher risk level require a more comprehensive form of treatment. The aetiology of dental erosion remained unknown to the patients, indicating a deficiency in their understanding of erosive tooth wear.

Materials and methods:

This prospective, single-blind randomized split-mouth clinical trial was done among 22 subjects diagnosed with chronic periodontitis. Periodontal parameters and mean log counts of porphyromonas gingivalis (P. gingivalis) evaluated using real-time polymerase chain reaction were recorded. SRP was performed both at control and test sites. The evaluation of clinical and microbiological parameters was done at baseline and 3 months’ post-intervention. Data were analyzed using Statistical Package for Social Sciences (SPSS) V.20 software.

Results:

While significant improvement in both clinical and microbiological parameters from baseline to three months was observed in both the test and control sites, the mean reduction in plaque index, periodontal pocket depth, and mean log colony-forming unit counts of P. gingivalis were significantly higher in the test sites compared to the control sites.

Conclusion:

The results of this study reject the null hypothesis in favor of the alternative hypothesis that adjunctive application of locally delivered aloe vera gel for the treatment of chronic periodontitis enhances the beneficial effects of mechanical therapy.
Efficiency of Jatamansi (Nardostachys Jatamansi [D. Don] DC.) and selected Yoga module in test anxiety of school-going children: A single-arm clinical trial
Authors: Arabi Fasnath , Jithesh M. , Shobhana M. C.
Published: June 2024

Introduction:

Test anxiety (TA) is a form of social evaluation anxiety experienced by individuals in a setting of assessment. Studies among students have reported an anxiety rate of 10%–30% which affects their overall performance. On analyzing the symptoms of TA, it is found that, there is a predominance of imbalance of Vata and Pitta humor. Jatamansi (Nardostachys Jatamansi [D. Don] DC.) has the property to balance all three Sharira Dosha (body humor) along with Manasa Dosha (psychic humor) and is hence widely used in psychiatric conditions. Several studies concluded that Yoga therapy is effective in various anxiety conditions.

Aim:

As the reported trials are less in TA from the Ayurvedic fraternity, this study aimed to evaluate the effect of Jatamansi and Yoga in test anxiety (TA) of school-going children.

Materials and methods:

Four hundred higher secondary students with age group 15-17 Yrs. were screened with TA self-assessment questionnaire after the quarterly examination. The 32 students satisfying the criteria and with informed assent, were selected for intervention, 45 days before the half-yearly examination. Jatamansi tablet was administered to the participants at the dose of two tablets (each of 500 mg) twice daily at 7 am and 7 pm with lukewarm water along with practicing 50 min of the selected Yoga module in the morning, continuously for 1 month. Assessments were done by the Westside TA scale (WSTAS) and Suinn TA behavior scale (STABS) before and after the intervention and after the half-yearly examination. The data were analyzed using paired “t-test.”

Results:

The total score of the WSTAS showed a statistically significant effect at the level of P < 0.001, which is suggestive of improvement in the wandering of mind, improving confidence, and concentration ability during the examination. Similarly, the total score of the STABS showed a statistically significant effect at the level of P < 0.001 suggesting improvement in anxious behavior during the examination. The scale showed highly significant results in anxiety at the level of P < 0.001 during preparation and after completing the examinations and at the level of P < 0.05. The drug does not show any drug tolerance or adverse drug reaction.

Conclusion:

The study concluded that there is a significant role for the Jatamansi tablet 500 mg twice daily along with a selected Yoga module for one month in reducing the test anxiety (TA) of school-going children.

Role of Multidetector Computed Tomography with Contrast in Evaluation of Congenital Lung Malformations in Pediatric Age Group at a Tertiary Care Hospital: An Observational Study
Authors: Sravya K. , Madhuri Sarukolla Meena , Veena M. , Vanaja B. , Bajaj Sunitha , Kumari Vijaya
Published: June 2024

Background:

Computed tomography (CT) has a larger role in the noninvasive examination of congenital lung abnormalities, thanks to the introduction of multidetector CT (MDCT). If a surgical lesion is suspected, it is often necessary to use cross-sectional imaging, such as CT, for diagnosis confirmation, further lesion definition, and preoperative evaluation.

Aims and Objectives:

The aim of this study was to enhance comprehension of the occurrence and varieties of congenital lung abnormalities in children, as well as to assess and compare the diagnostic precision of MDCT with that of surgical intervention.

Methodology:

MDCT with contrast CT was performed in children with respiratory complaints and prenatal history of suspicion in targeted imaging for fetal anomalies (TIFFA) or congenital lung malformations (CLMs) using TOSHIBA 8 slice CT; the study population consisted of 40 pediatric patients with a history of chest anomalies during pregnancy in TIFFA or children with abnormal chest X-ray suspicion of lung anomalies for 18 months.

Results:

In a study of 40 pediatric patients who underwent MDCT with contrast to evaluate CLMs, 6 were excluded from further evaluation with contrast due to the absence of pulmonary anomalies on plain CT, leaving a possible diagnosis of s CLM in the remaining 34 cases. Of these, cystic pulmonary airway malformations (CPAM) (41.1%) were the most common, followed by congenital lobar emphysema (17.6%), bronchogenic cyst (14.7%), lung agenesis (11.6%), and phylogenetic lung.

Conclusion:

To notice the characteristics and related anomalies of CLMs and aid in the presurgical evaluation of CLMs, the study concludes that MDCT with contrast is the imaging of choice.
Efficacy of Inhaled Corticosteroids in Patients with Bronchiectasis without Airway Hyperresponsiveness: A Pilot Study
Authors: Ahmed Safia , Sutravey Sesha Sai
Published: June 2024

Background:

The effect of inhaled corticosteroids (ICS) in stable cases of bronchiectasis without hyperresponsiveness has not been studied. The objective of the study was to assess the effect of inhaled fluticasone 500 µg twice daily on health-related quality of life (HRQoL), pulmonary function, and frequency of exacerbations in stable patients of bronchiectasis without bronchial hyperresponsiveness (BHR) diagnosed by indirect bronchoprovocation test.

Materials and Methods:

It was a pilot study with an open-label randomized control design conducted in a Tertiary Care Chest Hospital, with 40 patients in each arm. Bronchiectasis was diagnosed by high-resolution computed tomography chest. Patients with BHR were excluded by performing an indirect bronchoprovocation test using inhaled adenosine monophosphate. Eighty patients meeting the inclusion criteria were randomized into intervention group (IG) receiving 500 µg fluticasone propionate twice a day and control group (CG) receiving standard care without ICS. Both groups were assessed monthly till 6 months. Clinical data (mainly forced expiratory volume in 1st s [FEV1], number of exacerbations, HRQoL by St. George respiratory questionnaire (SGRQ) was collected at baseline and end of 6 months.

Results:

Eighty (IG - 40, CG - 40) patients of stable state noncystic fibrosis bronchiectasis completed the study. The mean age in our study was IG 49.7 ± 17.6 vs. CG 49.9 ± 16.6, males IG 62.5% vs. CG 60%, most common etiology was tuberculosis IG 40% (16/40) vs CG 37.5% (15/40). Difference in SGRQ score (baseline end of treatment) IG 5.47 vs. CG 1.65 (p = 0.00). Difference in FEV1 IG 0.054L vs. CG 0.004L (P = 0.00), mean number of exacerbations at end of treatment IG – 1 ± 0.9 vs. CG 1.2 ± 1.1.

Conclusion:

Patients with stable bronchiectasis without BHR, treated with inhaled fluticasone 500 µg twice daily for 6 months showed a clinically significant improvement in HRQoL. No statistically significant difference was seen in pulmonary function and frequency of exacerbations.

Published: June 2024

Introduction:

Ill effects of smoking and the advantage of smoking cessation on health are well reported. This study was undertaken with the aim to assess the Quality of Life (QOL) among smokers, non -smokers and ex-smokers which will help clinicians to point out the influence of smoking on quality of life to assist in their everyday work with the patients and to the researchers in more comprehensive evaluation of the respondents' life quality.

Materials and Methods:

The study was carried out among 234 current smokers, 233 non-smokers and 253 ex-smokers aged above 20 years using WHO- Quality of life- BREF(WHOQOL-BREF). Sociodemographic variables that were recorded includes age, Gender, educational status, marital status. Smoking history was obtained using a closed ended questionnaire. The collected data was entered in Windows Excel and statistical analysis was carried out using SPSS version 11 software. Descriptive statistics, One-way ANOVA test and Tukey's HSD Post hoc test was done. Level of significance was set as 0.05.

Results:

103(45.4%)smokers are 'satisfied' with their health, while majority of the ex-smokers,99(39.2%) are 'neither satisfied nor dissatisfied' with their health. Non-smokers reports higher mean values in all domains when compared to smokers and ex-smokers. The smokers showed higher rating in physical(53.39%) and environmental(52.7%) domains when compared to ex-smokers(50.56% and 59.21% respectively) while lower ratings were found in psychological and social domains among smokers than ex-smokers. Statistical test showed a significant difference among all groups based on domains except smokers and ex-smokers in psychological and social relationship.

Conclusion:

Quality of life among smokers are relatively lower than the non-smokers in the Physical health, Psychological, Social relationships and Environment attributes. Also, the ex-smokers are found to have similar quality of life as smokers when it comes to psychological and social relationship.
Homological Lagrangian monodromy for some monotone tori

Given a Lagrangian submanifold

A Study on the Nanban Trade and the Jesuit Missionary Expulsion Order in Early Modern Japan
Authors:   The Korean-Japanese Economics & Management Association, Kang Cheol-Gu , Lee Duk-Hoon
Published: June 2024

Purpose: This paper is an investigative study of the process from the introduction of flintlock guns by Polpogal trading ships in 1543, to Francisco Xavier's arrival in Japan six years later, to the edict expelling Jesuit missionaries in 1587.
Research design, data, and methodology: This was the period when Nobunaga of Japan appeared and ruled the country, and Nobunaga committed suicide due to the Honno-ji incident and Hideyoshi Toyotomo became his successor. Then came the Azuchi-Momoyama period, when Hideyoshi unified Japan and there was serious conflict between trade with Portugal and Christian missionary work.
Results: During the early modern Japanese Christian century (1549-1650), Christianity experienced an initial missionary period, a period of growth and development, and finally the appearance of martyrs. Nobunaga embraced Christianity to get rid of Buddhism, and Hideyoshi distributed an edict expelling Jesuit missionary Christianity to protect trade. During the Kirishitan century (1549-1650) in early modern Japan, Christianity went through a period of growth, a period of secrecy, and ultimately the emergence of martyrs. Nobunaga accepts Christianity to eliminate Buddhism, and Hideyoshi to promulgate an edict expelling Jesuit missionarie Christianity to protect trade.
Implications: Starting with Sumitada Omura in 1563, Yoshitaka Kuroda in 1577, Sorin Otomo in 1578, Harunobu Arima in 1580, Yukinaga Konishi in 1584, and others were baptized and a group of so-called Christian daimyo emerged. They burn down Japan's shrines and Buddhism, dedicate Nagasaki as an ecclesiastical ordinance, and Hideyoshi expresses his disquiet and promulgates an expulsion order for the Jesuit missionaries.
