Faunal dynamics in Majorca and Minorca during the 1st millenium BC
Authors: Ramis Damià
Published: December 2024

The human communities from Majorca and Minorca maintained very stable and traditional food customs during the Bronze and beginning of the Iron Age. The first new faunal introductions are detected in the Late Bronze Age and seem to be related to the consumption of exotic goods by the local communities. The archaeological record shows a very significant change during the second half of the 1st millennium BC which involved the new exploitation patterns of different faunal species, the introduction of new taxa and the beginning of the exploitation of existing resources such as dog and fish.
Luttes contre les injustices et construction des solidarités
Authors: Lamoureux Diane
Published: December 2024

Cet article explore les apports du paradigme de l’intersectionnalité visant à prendre en compte les « périls multiples » auxquels sont confrontés de nombreux acteurs sociaux. Sur le plan théorique, elles permettent d’analyser la complexité du social en termes de rapports sociaux qui produisent de l’injustice. Sur le plan politique, elles permettent de ne pas s’enfermer dans les politiques identitaires, ce qui signifie la possibilité, mais aussi la nécessité, de penser en termes de solidarité. La solidarité n’émerge pas spontanément d’une situation partagée ; elle exige un patient travail politique.
Blanchité, discrimination et intersectionnalité
Authors: Jotham Dolmare Maryse
Published: December 2024

Nous nous attacherons à démontrer que la question de l’identité blanche est centrale dans l’élucidation des mécanismes de pouvoir issus du système esclavagiste en vigueur du xvie au xixe siècle en Amérique et dans les Caraïbes. Nous montrerons que l’analyse intersectionnelle des discriminations permet d’une part de mettre en exergue la place centrale de la blanchité dans la compréhension des discriminations multiples et des mécanismes par lesquels s’exercent les dominations d’un groupe social sur un autre. D’autre part, elle permet une réflexion élargie sur le processus de co-création identitaire.
La Grande Guerre, une réaffirmation de l’identité créole
Authors: Ouali Thabette
Published: December 2024

Dans ce roman hommage au Bataillon créole, l’écrivain donne enfin la parole à ces soldats qui se sont battus « là-bas » ainsi qu’à leurs familles. Grands oubliés de l’Histoire, ce roman retrace leurs sacrifices, longtemps tus, pour défendre la mère patrie. Raphaël Confiant s’empare de la représentation commune de ce conflit mondial pour construire l’identité créole à travers le croisement des différentes prises de parole de ses personnages. Ces différents dialogues sur la Grande Guerre sont à lire comme un rappel d’un épisode historique longtemps tu et oublié. Ils sont non seulement une revendication de l’identité créole dans la réaffirmation de la filiation à la mère-patrie, mais surtout une revanche du nègre qui s’acquitte en apparence de sa dette envers le pays qui l’a libéré du joug de l’esclavage. De même, le choix esthétique signifie à son tour le cheminement de cette langue nouvelle capable de délivrer les âmes tourmentées et d’authentifier cette affirmation identitaire légitimée par les sacrifices de la Grande Guerre.
Raphaël Confiant ou « l’oiseau maître de son vol »
Authors: Pageaux Daniel-Henri
Published: December 2024

Ravines du devant-jour est lu non pas seulement comme un « récit d’enfance » ou un roman d’apprentissage, un « Bildungroman », mais comme un roman de la vocation. L’enfance, la jeunesse, les premières expériences de la vie sont relues dans la double perspective d’une sorte de prédestination et d’une réflexion sur la langue, mais surtout sur l’écriture. Le texte est avant tout l’affirmation d’une légitimité en tant qu’écrivain.
Critique de l’administration coloniale et de la « tropicalisation » du droit social français en Afrique Équatoriale Française : l’exemple de l’administrateur civil René Maran
Authors: Diouf Denis Assane , Ndione Lucienne Kodou
Published: December 2024

Basé sur l’examen du dossier administratif de René Maran, sur l’analyse de ses écrits littéraires et sur l’interprétation de textes législatifs coloniaux, ce travail, d’approche transdisciplinaire, démontre que cet administrateur civil est un homme du système, mais un anti-système. La critique assumée des brimades administratives dont il a été l’objet en tant que fonctionnaire de race noire, et la dénonciation des excès ou errements des administrateurs coloniaux, surtout en matière de réquisition et de traitement de la main d’œuvre indigène, ont certes contribué à classer Maran parmi ceux qui se sont retrouvés par « erreur dans l’Administration coloniale ». Mais ses prises de position tranchées, en tant que fonctionnaire colonial discriminé, ont réussi à briser le tabou de la transposition dévoyée, ou « la tropicalisation » du droit social dans les colonies françaises d’Afrique. Il n’est pas exagéré de voir en René Maran un instigateur de la réforme d’un droit social colonial.
Senghor, pédagogue et didacticien
Authors: Dumont Pierre
Published: December 2024

Pierre Dumont démontre, dans cette communication, que depuis 1936, date de sa célèbre conférence prononcée à la Chambre de Commerce de Dakar consacrée au problème culturel en Afrique de l’Ouest, jusqu’à la fin de ses jours, L.S. Senghor a été l’apôtre de la convergence des langues et des cultures en Afrique.
Léopold Sédar Senghor : le poète, l’écrivain et le politique ou Senghor l’Africain
Authors: Valantin Christian
Published: December 2024

Le parcours de Léopold Sédar Senghor, l’un des deux pères fondateurs du mouvement de la Négritude, est fascinant, comme le montre Christian Valentin dans son article, en ce qu’il part de l’Afrique profonde, ce village sérère où le futur poète passa sa prime enfance jusqu’à l’Académie française à la fin de sa vie, en passant par sa rencontre avec Aimé Césaire au Lycée Louis-Le-Grand à Paris dans les années 30 et la présidence de la toute jeune République du Sénégal en 1960. Profondément enraciné dans sa terre et sa culture, Senghor, par le miracle d’une poésie qui emprunte tout à la fois aux griots, chantres des royaumes africains, et aux grands poètes français tel que Claudel ou Saint-John Perse, a su atteindre à l’universel. Pétri d’humanisme, il a réussi à donner une résonance mondiale à la Négritude, notamment à travers sa vision d’une francophonie ouverte et fraternelle.
Suzanne Comhaire-Sylvain: The Roman de Bouqui, African folktales in the Caribbean
Authors: Ugochukwu Françoise
Published: December 2024

Suzanne Comhaire-Sylvain was Haiti’s first black female anthropologist. A student of Marcel Mauss and Bronisław Malinowski, she became a specialist in Creole and Haitian storytelling and conducted various studies on the status of women and oral literature in Africa. Her research focused primarily on Haitian folklore and on the origins of the Creole language, considered minor and worthless at the time. At a time when all over the world, academics were discovering traditional storytelling, she successively published Les Contes haïtiens (1937), Contes du pays d’Haïti (1938) and Le Roman de Bouqui (1940/1973). The publication of Le Roman de Bouqui triggered the process of rediscovery of Haitian oral literature, theorized in 1928 by Jean Price-Mars, revealing Bouqui as the golden thread taking us from Senegal to the rest of West Africa and the West Indies, always confronted to the same smart accomplice, there Leuk the hare or Tortoise, here Malice. This study will examine this third collection to reveal how it is built on the universal folktale structure, closely connected to African folktales, weaved around the trickster and his family, revealing the closeness of African and Haitian cultures.
De quoi l’écomusée/musée de société est-il le nom ? Jeux de vérité et de pouvoir dans la modernité
Authors: Barbe Noël
Published: December 2024

On avancera ici, d’abord, que les catégories « écomusée » et « musée de société » désignent moins un contenu qu’elles ne sont régulatrices de relations avec des populations, organisatrices des rapports entre l’État et les établissements qui s’en réclament, dans une tension entre l’hégémonie du paradigme de la représentation et celui de l’expression qui relève d’un minoritaire. Ensuite que la forme écomusée serait l’idiote utile de l’épistémologie politique de la modernité, parce que profondément marquée par quatre paradigmes de réduction d’un concret : un nationalisme et un naturalisme méthodologiques ; une conception linéaire du temps et le classement consécutif des choses et des êtres ; la représentation tout à la fois comme épistémologie et délégation. Si l’analytique est ici moléculaire, pour autant elle engage un désir de compréhension molaire, les expériences locales convoquées étant traversées à la fois par la modernité et non dépourvues de potentiel épistémologique.
Historicisation et pluralité
Authors: Huver Emmanuelle
Published: December 2024

RésuméDans cet article, qui est une (presque) réponse à Daniel Coste, nous nous demanderons ce que les notions d’historicité et d’historicisation peuvent « faire » à la didactique des langues, selon les époques, les enjeux, les histoires et les projets propres à ce domaine, dans leur diversité. Dans un premier temps, nous nous demanderons pourquoi historiciser la recherche en didactique des langues à partir de quelle conception de la didactique des langues et, en cohérence, de l’histoire. Dans un second temps, nous nous intéresserons aux enjeux et aux difficultés à historiciser la DDL à partir de l’historicisation de ses chercheurs.
Rencontrer les êtres autres qu’humains par le dialogue philosophique
Authors: Point Christophe , Champoux Mélanie
Published: December 2024

L’objectif de ce travail est d’interroger le potentiel et les limites de l’usage des pratiques du dialogue philosophique dans le contexte d’une éducation écologique, soit une éducation qui contribue à la formation de personnes consciemment reliées au monde. Comme modalité praxique de l’actualisation d’une telle éducation, nous esquissons les contours d’une pédagogie de la rencontre où les êtres humains et les êtres autres qu’humains peuvent se rencontrer, s’enrichir de leurs différences et composer un monde commun. Après avoir soulevé certains éléments d’une problématique psychosociale relative à l’existence de rapports au monde dévoyés, la première partie de l’article formule quelques avenues éducatives qui prennent l’allure d’un défi ontologique lancé aux systèmes d’éducation formelle dominants. La deuxième partie de l’article tente de répondre à ce défi en formulant quatre principes d’une pédagogie de la rencontre. Chacun de ces principes permet alors d’interroger les atouts et les limites des pratiques du dialogue philosophique au projet d’éducation écologique dessiné ici de manière spéculative.

Borderline: representaciones de la violencia y prácticas emancipadoras en la obra de Teresa Margolles
Authors: Fernández Eva
Published: December 2024

En este trabajo se articulará la noción de representación, como una fuerza des-ordenadora y crítica -en este caso de la violencia- y su potencialidad emancipadora, si se plantea desde las prácticas artísticas. Para abordar las imágenes de la liminalidad y de la muerte se analizará la exposición “El asesinato cambia el mundo”, en la James Cohan Gallery de New York en el 2020, de la artista mexicana Teresa Margolles quien problematiza, desde la materialidad y sus posibilidades objetuales en el arte contemporáneo, la violencia en un enclave limítrofe que afecta a mexicanos y a estadounidenses en un espacio/frontera signado por los conflictos migratorios y el narcotráfico. El manto negro, como la pieza más significativa para reflexionar sobre la representación de la violencia, es la instalación que desde la elaboración de cada uno de los objetos que componen la pieza materializa la experiencia del dolor y del duelo convirtiéndose en un gesto emancipador que insiste en nuevas imágenes. En una primera parte, se describirán los conceptos de representación, violencia y frontera, posteriormente, a través de una etnografía visual, se revisará la exposición de la artista mexicana y en una tercera parte conclusiva, se vincularán los conceptos y la obra desarrollados para argumentar la posibilidad emancipatoria que tienen las prácticas artísticas contemporáneas como proyectos de resistencia.
Frontera, violencia y emociones en tránsito. Una mirada a través la narrativa fílmica documental (2001-2019)
Authors: Zarza Rondón Gloria de los Ángeles
Published: December 2024

La presente contribución aborda el género documental centroamericano centrado en la travesía migrante. A partir de una selección de producciones que jalonan las dos primeras décadas del siglo XXI, se plantean las problemáticas asociadas al camino migratorio desde Centroamérica hasta la frontera con los Estados Unidos. En un primer apartado, conoceremos las vicisitudes de la travesía migrante y la cuestión fronteriza, aproximándonos al fenómeno migratorio desde la mirada más íntima y personal transmitida por estas narraciones fílmicas: el impacto emocional generado en las y los migrantes en tránsito. En un segundo apartado, centraremos la atención en la migración centroamericana a través de las experiencias de violencia, el dolor y las emociones de mujeres migrantes a partir de dos producciones, Los Invisibles (2010) y María en tierra de nadie (2011).
Entre lo visible y lo invisible. Fronteras representacionales de la violencia en el cine documental mexicano contemporáneo.
Authors: Murillo Tenorio Ilse Mayté
Published: December 2024

Las violencias sociales resultan un tema relevante a destacar dentro de las representaciones cinematográficas mexicanas. En las últimas dos décadas han estado centradas en violencias vinculadas con el fenómeno del narcotráfico y de los feminicidios. Actualmente existe un corpus numeroso de filmes, tanto de ficción como de no ficción, muchas de éstas rozando entre la expresión legítima de una denuncia social o política y la sobreexplotación gráfica de la violencia. En contraste, han surgido algunas propuestas de carácter documental, tales como Tempestad (Tatiana Huezo, 2016) y La libertad del diablo (Everardo González, 2017), que abordan estas violencias desde otras enunciaciones que deambulan entre las fronteras de lo visible y lo no visible. Con base en dichas obras fílmicas, proponemos hablar de las formas de representación de las violencias que se construyen desde la enunciación de la palabra primordialmente, recuperada a través del ejercicio testimonial como la entrevista y el uso de la voz en off, recursos clave del cine documental que funcionan para alejarse de las violencias gráficas y así problematizar sobre las fronteras de lo visible y de lo invisible y el uso formal que le da el cine documental.
Fantología cinematográfica de las violencias políticas en tres coproducciones franco-latinoamericanas
Authors: Thibaudeau Pascale
Published: December 2024

Este trabajo propone estudiar la memoria de las violencias políticas desde una doble perspectiva: la de los géneros cinematográficos que ofrecen distintas modalidades de aproximación a la realidad y desde la noción de fantología desarrollada por el filósofo Jacques Derrida, que contempla lo espectral como inherente a la realidad misma y al lenguaje. Para ello nos centramos en tres películas recientes sobre episodios de violencia histórica, cuya presencia en las memorias actuales vienen actualizadas cinematográficamente mediante fenómenos espectrales que cobran distintas formas. La Llorona (Jayro Bustamante, 2019) trata del juicio al dictador Enrique Monteverde (alter ego de Efraín Ríos Montt) y del genocidio contra los indígenas recurriendo a los códigos del género fantástico y de terror; Los silencios (Beatriz Seigner, 2018) aborda el conflicto armado en Colombia desde pautas propias de lo real maravilloso, mientras que Nuestras madres (César Díaz, 2019) vuelve sobre el genocidio guatemalteco desde una perspectiva “documentalizante”. Veremos cómo estas tres formas de referirse a realidades violentas del pasado, a pesar de sus diferencias genéricas, no dejan de activar paradigmas espectrales compartidos.
"You are hearing the heart of the world, the heart of the huéhetl”: the folk songs and books of Concha Michel
Authors: Noriega Vega Cecilia Itzel
Published: December 2024

Concha Michel was a singer-songwriter, researcher, and fighter for women's rights during the post-revolutionary period. Throughout her life, she carried out important research on pre-Hispanic music. Likewise, she wrote plays, folk songs, and texts explaining her feminist position such as “Marxists and Marxists” (1934), Two Fundamental Antagonisms (1938), God Our Lady (1966); and God-Principle is the couple (1974). Her productions were influenced by her participation in the Mexican Communist Party, her trip to the USSR, and the Mexican cultural context of the post-revolution. Through these texts she denounced feminicide and post-revolutionary heteropatriarchal culture. At the same time, she criticized the Mexican Communist Party, because it displaced women's problems. Finally, Michel's contributions were decisive for the Mexican cultural context of the first half of the 20th century, because she established bridges between literature, music, and artwork.
Exploring the crisis of subjectivity through the interplay between feminist ideology and historical consciousness in ‘postsocialist art history’, or the emergence of the Millennial art historian from the contradiction between the autonomization and privatization of culture
Authors: Antonova Natalya
Published: December 2024

Consciousness-raising – positioned as the epitome of feminist method and its end goal – narrows feminist historical consciousness to an individual or group identity and overlooks the question of ideological formation: this is one of the markers of the crisis of subjectivity in feminist theory, as this essay suggests. The essay reveals the critical role of, and historicizes, feminist ideology in the Anglophone feminist critique of feminist cultural production evolving since the late 2000s in “postsocialist art history”. The feminist critique of feminist cultural production has raised the pertinent question of the autonomy of the art historian amid the ongoing privatization of culture inflicted by the global impasse of socialist politics since at least the last quarter of the 20th century and sustained by philanthropic capital. Emerging researchers of feminist art still face this historical conundrum.
Motherpumping: women-artists-mothers-scholars-etc. discussing the art system from Brazilian viewpoints
Authors: Farias Sommer Michelle
Published: December 2024

In light of the debate concerning women-artists and women-artist-mothers-etc. in the art system, and the introduction of “motherhood” as a topic in academia, this essay aims to contribute to research on conditions for artistic and theoretical practices and forms of legitimation vis-à-vis this particular segment. The association between feminisms-art-motherhood-academia locates viewpoints in Brazil, under the sway both of a precarization of reproductive rights and the absence of structural resources either from the state or from private sources. Taking this context into consideration, the essay is geared towards the question: from the force of creation – taken here in its more literal meaning – to the addressing of artistic-theoretical practices by female art (re)producers, what does the word “mother”, in association with women-artists and women-artists-scholars-etc., evoke nowadays? contemporary art, feminisms, motherhood, academia.
Correlation of Wear Behavior of PBT/PC Blend with Crystallographic Structure: A Comprehensive Study on Wear Rate and Crystal Structure
Authors: Mane Prajakta , Keche Ashok J. , Chopra Swamini
Published: December 2024

Polymer blends, particularly those containing Polybutylene terephthalate (PBT) and Polycarbonate (PC), are extensively utilized in various industrial applications due to their favorable mechanical and thermal properties. Enhancing the performance of such blends necessitates an understanding of the relationship between their crystalline structure and wear behavior. This study investigates the correlation between wear characteristics and structural aspects of PBT/PC blends having varying PC content. Additionally, techniques such as X-ray diffraction (XRD) and optical microscopy of the worn-out surface are employed. The findings reveal a strong connection between the wear behavior of PBT/PC blends and their crystallographic structure. This study provides useful insights into the wear mechanism and crystallization behavior of PBT/PC blends. Specifically, it is observed that with increasing PC content in the blends, the wear resistance is influenced by the size of crystallites, wherein smaller crystallites demonstrate a greater ability to withstand abrasive action-induced damage. The wear performance of the PBT/PC blend with 70% PC improves by ~37% as a result of the formation of a semi-orderly chain structure with a smaller crystallite size. A mechanism is also explained herein related to the change in the nature of crystallization of PBT/PC blends with increasing PC content. In conclusion, this study underscores the importance of considering crystallographic structure when assessing the wear behavior of polymer blends such as PBT/PC.

Authors: Panji Chandana , Yavagal Pavankumar , Kulkarni Vinayak N. , Gurusiddayya S.G. , Chakravarthy N.Deeban , Rawal Yash
Published: December 2024

This study investigates the careful investigation of cutting parameters to improve machining effectiveness and increase tool life while milling Nickel-Titanium Shape Memory alloy (NiTiNOL). The NiTiNOL material is employed to manufacture components such as, dental braces, seismic dampers and medical implants. Using Finite Element (FE) simulation, the research closely examines the intricate interactions among parameters, such as feed rate (fr), depth of cut (D), and cutting speed (Vc). The use of Response Surface Methodology (RSM) and Taguchi has been used to determine the most optimal settings for tool longevity and machining efficiency. The FE simulation model provides a strong framework to investigate how cutting parameters affect necessary reactions. The present study examines interactions among parameters like cutting speed, depth of cut, and feed rate. Moderate cutting speed, lower depth of cut, and the highest feed rate has induced lower stress in the workpiece. This study adds to understanding NiTiNOL alloy machining fundamentals and offers useful information for industry applications. To attain better machining results while milling NiTiNOL alloy, the results are intended to guide an optimization technique
Topotecan Incorporation Into Avocado Oil-based Nanoemulsion Potentiates Its Inhibitory Effect on the Cellular Growth of Various Human Cancer Cells
Authors: Alkhatib Mayson H. , Bayoumi Hadeel M.
Published: December 2024

Background:

The aim is to ameliorate the anticancer activity of topotecan (topoisomerase [TOPO]) by solubilizing it in a nanoemulsion (NE) delivery system containing avocado oil (AO), then to assess its cytotoxicity in MCF-7 breast, HCT116 colon, HeLa cervical, and HepG2 liver cancer cells.

Methods:

AO-NE formulation was developed using an ultrasonic homogenizer and characterized by a zeta-sizer and transmission electron microscope (TEM). The effects of the TOPO-AO-NE formula on viability, cellular and nuclear morphology of cancer cells, as well as TOPO cellular accumulation, inflammatory effects, apoptosis, and autophagy, were examined.

Results:

The nanosized particles of the AO-NE formula were negatively charged (114.83 ± 1.10 nm, −8.96 ± 0.14 mV) even after TOPO loading (75.44 ± 8.51 nm,−5.79 ± 0.38 mV). In contrast to free TOPO, TOPO-AO-NE exhibited significant anti-proliferation, clear apoptotic changes, improved TOPO cellular uptake and decreased IC50 from (12.65 ± 0.05, 15.78 ± 0.08, 26.82 ± 0.50, and 5.50 ± 0.50 μM) to (2.35 ± 0.05, 4.90 ± 0.05, 2.58 ± 0.08, and 4.87 ± 0.08 μM) in MCF-7, HCT116, HeLa, and HepG2 cells, respectively. In MCF-7 and HCT116 cells, cytotoxicity of TOPO-AO-NE was attributed to decreased IL-6 levels relative to a negative control, lessened autophagic LC-3 levels compared to free TOPO-treated cells, and induction of type-I apoptotic cell death. In HeLa cells, TOPO-AO-NE-induced apoptosis through autophagy inhibition and induction of type-I apoptosis. In HepG2 cells, AO-NE reduced IL-6 cytokines and induced both type-I-apoptotic and type-II-autophagic cell deaths in comparison with control cells.

Conclusion:

Loading TOPO in AO-NE has dramatically enhanced its’ antiproliferative effects in cancer cells.

Authors: Bajaj Nidhisha , Kumar Nand , Kumar Rakesh , Patil Vaibhav , Sharma Anshul
Published: December 2024

Background:

Intermittent theta burst stimulation (iTBS) is an accepted and approved brain stimulation technique to treat patients with treatment-resistant depression.

Aim:

Using neuroimaging, this open-label study aimed to predict the response by observing glucose metabolism with the help of 18-FDG PET scan.

Methods:

A total of 25 treatment-resistant depression patients received 15 sessions of iTBS on the left dorsolateral prefrontal cortex. Two FDG-PET scans were done for all the patients. Fifty-six percent of patients responded to treatment with iTBS.

Results:

We found that there was hypometabolism in left and right prefrontal lateral regions, left and right inferior parietal regions, and left prefrontal medial regions at baseline but no statistically significant difference in the metabolism between responders and nonresponders.

Conclusion:

We did not find any statistically significant difference in the metabolism between responders and nonresponders in any brain regions at T0 as well as T1. Further large-scale studies are required.
Prevalence and factors associated with high risk for obstructive sleep apnea in schizophrenia spectrum disorder patients on long-term clozapine
Authors: Rijal Rika , Grover Sandeep , Chakrabarti Subho , Sahoo Swapnajeet
Published: December 2024

Aim:

This study aimed to evaluate the prevalence of obstructive sleep apnea (OSA) and its correlates among schizophrenia spectrum disorder patients receiving clozapine.

Methods:

For this, 200 schizophrenia spectrum disorder patients receiving clozapine for at least one year were assessed on the Berlin Sleep Questionnaire for OSA.

Results:

Around one-sixth of the study sample (16.5%) had a high risk for OSA at a body mass index (BMI) cut-off of 30 kg/m2. When a BMI cut-off of 25 kg/m2 was used, the prevalence of OSA was 36%. A high risk for OSA is associated with a higher prevalence of depression, a higher number of psychiatric comorbidities, diabetes mellitus, a higher mean total chlorpromazine equivalent dose, a higher number of total medications, poorer quality of life in some of the domains, and scored high for all domains and the total score of UKU.

Conclusion:

To conclude, this study suggests that a high risk of OSA is associated with the presence of depression, a higher number of psychiatric comorbidities, diabetes mellitus, use of higher total chlorpromazine equivalent dose, the total number of medications, poorer quality of life, and a higher prevalence of other side effects.
Pharmaceutical and analytical study on modified dosage form (tablet) of Vidanga Tandula Rasayana: An Ayurveda Rasayana formulation
Authors: Shetty P. Shifa , Deogade Meena , Ghildiyal Shivani , Bhide Bhargav , Nesari Tanuja Manoj
Published: December 2024

BACKGROUND:

Rasayana (immunomodulator) is integral to Ayurveda and offers a significant understanding of longevity and health promotion. However, their integration into contemporary healthcare necessitates adapting them into modern dosage forms for ease of utility and broader dispensing. This study focuses on the pharmaceutical and analytical aspects of a modified dosage form as a tablet derived from the classical Ayurveda immunomodulator formulation, Vidanga Tandula Rasayana (VTR).

METHODS:

For the preparation of VTR, equal parts of Yastimadhu and Vidanga powders were taken and mixed with honey, which is used as Sahapana in the textual reference, along with a binding agent. The reference was taken from the classical text, Sushruta Samhita—the reference method for tablet preparation as per the Ayurvedic Pharmacopoeia of India. The tablet was subjected to physicochemical analyses, which included a loss on drying, total ash, acid-insoluble ash, and aqueous and alcohol-soluble extractives. Additionally, powder microscopic analysis was conducted to evaluate the presence of characteristic cells and structures indicative of the ingredients. Qualitative phytochemical screening and analytical specifications of the tablet were assessed to ascertain its quality and for standardization purposes. Tests related to toxic contaminants such as microbial load, heavy metals, and aflatoxins were also performed.

OBSERVATION AND RESULTS:

Results revealed that all physicochemical parameters were within the general defined limits of tablets. While powder microscopy confirmed the presence of specific cellular features consistent with the ingredients, the tablet’s analytical specifications also met standard requirements. The microbial contaminants and aflatoxins were below detectable limits. Heavy metal levels were within acceptable ranges.

CONCLUSION:

The pharmaceutical and analytical evaluation indicates that VTR can be modified into tablet form, which has several advantages such as ease of dispensing, better shelf life, fixed dosage administration, and ease of dispensing. The present work can be considered an innovative and preliminary attempt at pharmaceutical and analytical evaluation of VTR.

Authors: Tank Bansri , Shah Rupal J. , Marwaha Gunjit , Chauhan Neelima , Chheda Ekta , Shah Om
Published: December 2024

ABSTRACT

Background:

The precise recording and transfer of maxillo-mandibular relationships are pivotal in prosthetic treatments.

Aims and Objectives:

To evaluate the efficacy of four bite registration materials: alu wax, hard wax, polyvinylsiloxane, and bis-acrylic resin, in accurately recording, maintaining, and reproducing the vertical interocclusal relationship on either side of the dentition.

Materials and Methods:

Thirty subjects within the age group of 20–45 years were selected. The difference in the reading of the vertical distance with the material and at maximum intercuspation is calculated individually for each record on the left and right sides.

Results:

On the right side, the lowest mean was observed in MIP and the highest in hard wax. On the left side, the lowest mean was observed in MIP, while the highest was in alu wax. Among the four bite registration materials evaluated, Luxabite and Jetbite exhibited the highest mean accuracy scores.

Conclusions:

Closure on interocclusal record material and bite release produce vertical discrepancies. Waxes showed the most, and bis-acrylic Luxabite and addition silicones showed the least dimensional distortion vertically.

Assessment of Condylar Position and Its Association with Unilateral TMD in Patients with Angle’s Class I, II, and III Malocclusions Using CBCT
Authors: Mehta Dollchi , Swaminarayan Dhruv , Patel Nikita , Arsheed Noor Addeen Abo , Rai Narendra Prakash , Fakhra Ismat
Published: December 2024

ABSTRACT

Introduction:

With cone beam computed tomography (CBCT) as a diagnostic tool, we compare and analyze the condylar position and its relationship with unilateral temporomandibular disorder (TMD) in patients with Angle’s Class I, II, and III malocclusions.

Materials and Methods:

The association between TMD and age, gender, vertical condyle position, horizontal condyle position, and steepness of articular eminence in individuals with various malocclusions was examined using 30 CBCT images.

Results:

The asymptomatic group shared the concentric location of the condyle in their respective mandibular fossae, which is also a typical hallmark of Class II and Class III malocclusion on the left temporomandibular joint. Patients with TMD were more likely to be in the posterior condylar position. In all malocclusions and TMD cases, the condylar head’s vertical position was mostly normal and slightly elevated. All malocclusions and TMD patients had moderate to severe articular eminence steepness. In individuals with TMD and malocclusions, the mesiodistal breadth of was considerable on the left side.

Conclusion:

Future research should be done with a larger sample size and an emphasis on assessing how the condyle’s location will change after therapy for patients with TMD.
Therapeutic effects of low-intensity transcranial focused ultrasound stimulation on ischemic stroke in rats: an in vivo evaluation using electrical impedance tomography

Although previous studies have demonstrated that transcranial focused ultrasound stimulation protects the ischemic brain, clear criteria for the stimulation time window and intensity are lacking. Electrical impedance tomography enables real-time monitoring of changes in cerebral blood perfusion within the ischemic brain, but investigating the feasibility of using this method to assess post-stroke rehabilitation in vivo remains critical. In this study, ischemic stroke was induced in rats through middle cerebral artery occlusion surgery. Transcranial focused ultrasound stimulation was used to treat the rat model of ischemia, and electrical impedance tomography was used to measure impedance during both the acute stage of ischemia and the rehabilitation stage following the stimulation. Electrical impedance tomography results indicated that cerebral impedance increased after the onset of ischemia and decreased following transcranial focused ultrasound stimulation. Furthermore, the stimulation promoted motor function recovery, reduced cerebral infarction volume in the rat model of ischemic stroke, and induced the expression of brain-derived neurotrophic factor in the ischemic brain. Our results also revealed a significant correlation between the impedance of the ischemic brain post-intervention and improvements in behavioral scores and infarct volume. This study shows that daily administration of transcranial focused ultrasound stimulation for 20 minutes to the ischemic hemisphere 24 hours after cerebral ischemia enhanced motor recovery in a rat model of ischemia. Additionally, our findings indicate that electrical impedance tomography can serve as a valuable tool for quantitatively evaluating rehabilitation after ischemic stroke in vivo. These findings suggest the feasibility of using impedance data collected via electrical impedance tomography to clinically assess the effects of rehabilitatory interventions for patients with ischemic stroke.

The study was conducted to assess the effect of mercuric chloride (HgCl2) on the ovary and the hormonal changes associated with it. Sixteen (16) Wistar rats weighing between 180 g – 280 g and of both genders were separated randomly into 4 groups of four animals each after copulation has been confirmed. Groups B, C and D, received 4mg/kg, 6mg/kg and 8mg/kg respectively body weight of mercuric chloride solution for 28 days, while Group A was the control rats received distilled water as contained in the experimental doses. The rats were anesthetized using chloroform, dissected and blood samples for hormonal assay were collected by retro orbital process. The ovaries were removed and fixed in 10% neutral buffered formalin. They were weighed and processed for histological studies using H & E staining techniques. There was insignificant reduction (p>0.05) in weight (213.0 ± 3.52g) when compared to the control group. There was significant reduction (p<0.05) in LH (2.3 ± 0.55mlU/ml) and FSH (0.167 ± 0.005mlU/ml) when compared to the control group. There was insignificant reduction (p>0.05) in EH (0.090 pg/mL). The histology of the ovaries reveals degenerative changes with increasing formation of fibrosis and hyalinized stroma.
Firm decisions under uncertainty in a two-sided market: a ‘film industry’ classroom game
Authors: Sanchez Sofia Izquierdo
Published: December 2024

This paper outlines the development of a film industry game that helps students comprehend the structure of a two-sided market and analyse the dynamics of producing goods in the creative industries. The game demonstrates the significance of a firm’s decision-making in this context and how various strategies can impact revenue. It is designed for undergraduate and graduate students studying Microeconomics, Industrial Organisation, or more specific Media and Cultural Economics modules, explicitly focusing on the creative industries. The game provides a learning experience by allowing students to simulate real-world scenarios. It encourages critical thinking as participants navigate the complexities of the film industry, making decisions that mirror the strategic considerations faced by creative firms in a dynamic two-sided market.
Teaching time use in economics classes: introducing students to time poverty and inequality in unpaid work
Authors: Small Sarah F. , Beltran Figueroa Laura
Published: December 2024

This article describes a brief module for economics courses in which students learn about inequality through the lens of time-use data. Economic research on time use is common in feminist, gender, New Home, and development economics and has been pivotal for understanding inequality in unpaid work. This course module provides an opportunity for economics instructors to enhance students’ understandings of inequality as well as data collection. We offer a roadmap for instructors that includes (1) an introduction to time-use data, (2) an exercise for students to record their own time-use diaries and compare these with national averages, and (3) an exercise for students to consider measures of time poverty. We offer this module specifically for instructors searching for opportunities to infuse feminist economic perspectives in their courses.
Les ruses du « oui » et du « non », ou les incertitudes du consentement sexuel et littéraire
Authors: Merlin-Kajman Hélène
Published: December 2024

Taking as its starting point a controversy over the interpretation of a poem by Chénier in which some readers saw the representation of a rape, this article examines the historicity of the signs of female sexual consent and the issues of a literary reading that allows for confusion and vacillation, characteristics that are conducive to education in a sexuality that is itself based on consent.
De Verny indygenat szlachectwa polskiego
Authors: Zywert Eryk
Published: December 2024

The reign of Stanisław II August (1764–1795) was a period of generous distribution of titles of nobility in the Polish-Lithuanian Commonwealth. Bringing in and promoting foreign elites was seen as a chance to lift the Polish-Lithuanian elective monarchy out of the crisis that had been deepening since the socalled Saxon times (1697–1763). This policy was served by the granting of indygenat, which gave the status of Polish nobility to foreign nobles. This status was given to members of de Verny family from Lorraine, who, being loyal to their new homeland, made efforts to preserve its existence.
Porady prawne udzielane na łamach Nowego Kuriera Warszawskiego w latach 1940–1944
Authors: Mielnik Hubert
Published: December 2024

The article presents a study dedicated to the analysis of legal advice given in Nowy Kurier Warszawski, a Polish-language German newspaper published in the General Government during World War II. The publication is primarily based on an analysis of press sources, employing a quantitative research methodology. It aims to answer the following research questions: How much advice was given each year? What was the average distribution per issue? Which legal fields were covered by the legal advice, and in which fields was the most advice given? What was the distribution between legal advice regarding pre-war law and German legislation? What were the main types of cases (problems) within each category of the provided legal advice? To what extent, if at all, was legal advice instrumental in imposing the German perspective (interpretation of the law)? Through the analysis of the legal advice provided to readers, the author intends to present a partial picture of everyday life in the General Government. The thesis of the article posits that the legal advice published in Nowy Kurier Warszawski primarily had an informational character for the residents of the General Government, often concerning issues that extended far beyond the legal sphere. They were not a tool of propaganda for the German authorities’ legal system.
Unifying cubical and multimodal type theory
Authors: Aagaard Frederik Lerbjerg , Kristensen Magnus Baunsgaard , Gratzer Daniel , Birkedal Lars
Published: December 2024

In this paper we combine the principled approach to modalities from multimodal type theory (MTT) with the computationally well-behaved realization of identity types from cubical type theory (CTT). The result -- cubical modal type theory (Cubical MTT) -- has the desirable features of both systems. In fact, the whole is more than the sum of its parts: Cubical MTT validates desirable extensionality principles for modalities that MTT only supported through ad hoc means. We investigate the semantics of Cubical MTT and provide an axiomatic approach to producing models of Cubical MTT based on the internal language of topoi and use it to construct presheaf models. Finally, we demonstrate the practicality and utility of this axiomatic approach to models by constructing a model of (cubical) guarded recursion in a cubical version of the topos of trees. We then use this model to justify an axiomatization of L\"ob induction and thereby use Cubical MTT to smoothly reason about guarded recursion.

Likidite riski ve yönetimi yakın geçmişte hem bankacılık sektörünün hem de bankacılık otoritelerin
üzerine yoğunlaştığı bir konu olarak karşımıza çıkmaktadır. 2008 finansal krizi ve beraberinde
bankacılıkta likidite hem bankacılık sektörünün hem de bankacılık otoritelerin üzerine yoğunlaştığı bir
konu olarak karşımıza çıkmaktadır. İhtiyatlılık üzerine kurulu likidite riski ve yönetimi ile risk üzerine
kurulu karlılık arasındaki muhtemel ödünleşmenin, bankacılık faaliyetlerinin sürdürülebilirliği adına
önemli bir araştırma konusu olduğu değerlendirilmektedir. Bu çalışmada, likiditeye ilişkin göstergeler
ile karlılık göstergeleri arasındaki ilişki panel veri yöntemiyle değerlendirilmiştir. 2010-2023 dönemine
ait çeyreklik bazdaki verilerin kullanıldığı modellerde Türk bankacılık sektöründe yer alan 22 mevduat
ve 6 katılım bankası kapsama dahil edilmiştir. Sektör, mevduat ve katılım bankalarının ayrı ayrı
değerlendirildiği modellerde genel olarak tahmin sonuçları, likidite göstergelerinden son dönemdeki
düzenlemelerle gelen ve bankalar tarafından uyum sağlanması gereken likidite karşılama oranı ile
karlılık göstergeleri arasında negatif yönlü bir ilişki olduğu, literatürde kullanılan ve görece daha eski
bir likidite göstergesi olan likit varlık/toplam varlık oranı ile karlılık göstergeleri arasında pozitif yönlü
bir ilişki olduğu sonuçlarına ulaşılmaktadır.

Authors: Reyna Gracia Enela Marbel , Delgado Cobeña Elan Ignacio
Published: December 2024

Over the years, pedagogical models have guided the teaching process in the area of Social Studies, through dynamic environments to transmit scientific knowledge effectively. The main objective of the present study was to characterize the use of pedagogical models in the basic teaching of Social Studies. The methodology employed was of mixed approach, combining quantitative and qualitative methods in data collection. The population selected for the study included 50 teachers from four types of educational institutions. Survey and interview techniques were used, in this sense, quantitative data were analyzed through the application of descriptive statistics and for the interview data, qualitative coding was used. The results revealed deficiencies in the application of a standardized pedagogical model adapted to the current generation of students. The teachers expressed their interest in acquiring new teaching methods to improve the learning of their subject, however, they considered that the humanistic model needs to be worked on with the students. To conclude, the detailed characterization of the importance, characteristics and timely application of the pedagogical models was fundamental for the strengthening of knowledge in teachers and students.
