State violence and last sentences in Thomas Kyd’s Spanish Tragedy
Authors: Oziol Nathalie
Published: December 2022

At a time when the dying speeches of those condemned on the public scaffold were skilfully organised so as to reinforce the king’s power, Thomas Kyd’s most famous play, The Spanish Tragedy, is outstanding for the freedom with which it stages execution scenes and allows characters condemned to death to deliver their last speeches. Their words indicate abusive power, excessive violence and, therefore, an unjust justice enforced in the name of the monarch. The rhetoric of the condemned thus speaks the truth while the last dying speech takes on various forms, whether oral, written, or even posthumous, so as to create dramatic twists and, more significantly, allow the revenge which determines the play’s genre to take place.
La mort n’est pas une fin. La scène d’exécution est-elle vraiment une « scène à faire » ?
Authors: Labrune Caroline
Published: December 2022

Alors que la scène d’exécution semble être une « scène à faire » dans la tragédie du XVIIe siècle, elle se dissout parfois dans le néant. Dans Polyeucte martyr de Corneille et dans Athalie de Racine, elle devient une « scène à faire valoir » parce qu’elle s’efface devant des enjeux religieux supérieurs. De leur côté, dans Le Véritable Saint Genest et dans La Mort d’Agrippine, Rotrou et Cyrano de Bergerac ne développent pas l’exécution précisément parce qu’elle constitue d’ordinaire une « scène à faire ». Comme l’un rejette la tradition qui fait du martyre une gloire universellement reconnue, et que l’autre cherche à heurter son public de front, l’exécution devient une « scène à éviter ». Ainsi n’est-elle pas toujours une fin dans la tragédie du XVIIe siècle.
Marriage bed manoeuvrings: sociopolitical functions of the bed in the 1647 folio text of John Fletcher’s The Woman’s Prize, Or The Tamer Tamed
Authors: Sharrett Elizabeth
Published: December 2022

This essay explores the use of the prop bed in the 1647 Folio text of John Fletcher’s The Woman’s Prize, Or The Tamer Tamed (1610), and the manner in which the object becomes an emblem of female marital control. It argues that Livia’s manipulation of the bed serves as the means by which she subverts the traditional patriarchal negotiation of marriage. Informing this reading is an examination of the seemingly antithetical embrace of marriage and death in early modern culture as laid out in the 1559 Book of Common Prayer’s service of matrimony, and reinforced in visual culture in circulation at the time; indeed it is from her supposed sickbed that Livia arranges her match to the man of her choice. In doing so, Fletcher presents an onstage version of the bedtrick. Yet while the Folio presents this subversive use of the bed, it is ironically Livia’s adherence to a number of ideal components of the marriage ritual, including the signing of a contract, the observation of a kind of wedding-night bedding ceremony, and the participation of the wider family and community in the event as witnesses, which serves to secure the legitimacy of the match in the end.
La justice spectaculaire : L’exécution des sentences, pratiques et représentation théâtrale
Authors: Fragonard Marie-Madeleine
Published: December 2022

L’« exécution » est celle d’une sentence, un fait juridique, ordonné, qui fait l’objet d’un rituel précis au nom d’une autorité légitime : un usage pédagogique et cathartique de l’horreur. Elle s’oppose au meurtre, à la vengeance, à la conspiration, comme au « coup de majesté ». La période 1550-1650, féconde en bouleversements politiques, voit au théâtre une transposition des problématiques qui régissent l’acte violent et la loi qui l’ordonne. Mise en récit et mise en scène mettent en cause des pouvoirs et les réactions des spectateurs. Ceux-ci, éduqués par l’expérience, par le théâtre religieux (où les exécutions sont une norme sanctifiante), parfois par le flou qui entoure le pouvoir des rois antiques ou lointains, confrontent des valeurs contradictoires avec les exécutions « modernes » : l’ambiguïté entre pouvoir royal et décision judiciaire explicite, choix personnel et conseillers, passion et justice, délectation de la violence et décence du récit, efficacité et légalité interrogent sur la légitimité de l’ordre donné.
« La tête qui bondit », ou la décollation de Marie Stuart
Authors: Brailowsky Yan
Published: December 2022

Les scènes d’exécution révèlent les liens entre le spectaculaire et le punitif (Michel Foucault), mais elles sont difficiles à mettre en scène, plus encore lorsque le sujet est la décollation de Marie Stuart, dont l’exécution divisa catholiques et protestants, obligeant les dramaturges à adopter plusieurs stratégies de médiation. En prenant l’exemple de pièces de John Pickeryng (Horestes, 1567), Jean de Montchrestien (L’Escossoise, 1604) et Charles Regnault (Marie Stuard Reyne d’Ecosse, 1638), on verra comment les dramaturges nous font vivre la mise à mort (et la reine défunte), et donnent à voir cet épisode morbide malgré son absence sur scène, notamment au moyen de détails étonnants, comme celle de la « tête qui bondit » de Marie Stuart.
Entre « philosophie » et « religion ». L’image des lettrés chinois selon Alessandro Valignano au tournant de l’année 1588
Authors: Chuang Hsin-Tien
Published: December 2022

Nous proposons d’observer deux catégories occidentales dont les jésuites se sont servis pour décrire la pensée chinoise dans leurs premières descriptions sur la Chine : la « philosophie » et la « religion ». Pour cela, nous examinons trois écrits d’Alessandro Valignano S. J. (1539-1606), chef suprême de la mission en Chine et au Japon : l’Historia del principio y progresso de la Compañía de Jesús en las Indias orientales (1542-64) de 1583 ; une lettre de Valignano adressée au Général Claudio Acquaviva (1543-1615), datée du 11 novembre 1588 ; le De missione legatorum iaponensium ad Romanam Curiam publié en 1590. L’image du confucianisme qui était présentée en tant que « philosophie » indifférente, voire opposée à la « religion », bascule dans le champ de la « religion ».
Representing Catholic Europe: Alessandro Valignano and De Missione (1590)
Authors: Pelliccia Carlo
Published: December 2022

The following article examines the information that De Missione (Macau, 1590) means to convey to Japan about Catholic Europe. This work narrates the journey West of four boys from the Arima seminary to pay homage to Gregory XIII and Philip II. De Missione contributes to the phenomenon of mutual knowledge and cultural interaction between Europe and Japan, envisioned by Alessandro Valignano. Indeed, this volume aimed to introduce the Western world to the Japanese people by showing them the magnificence and authority of Catholic Europe with its history, society, culture and religion. The appendix contains the unpublished Letters Patent written by Superior General Claudio Acquaviva for the ambassadors, so that they would be welcomed in the residences and colleges of the Society of Jesus on the Italian Peninsula.
Encounters? The De missione dialogus, its Cosmographic Discourses, and the Global Projection of Christian Europe’s Alleged Superiority
Authors: Cattaneo Angelo
Published: December 2022

This essay analyses the epistemological foundations of the use and functions of cosmography, geography and cartography in the De missione dialogus as a way to sustain the European moral and scientific alleged superiority with respect to all other civilizations. Since the padre visitador Alessandro Valignano S. J. (1539-1606) outlined the geographical discourse of the De missione by following Abraham Ortelius's Theatrum orbis terrarum (1570), this study will also allow to analyze a specific use of the Theatrum for Catholic missionary purposes. On the basis of extant research on the reception of Western iconography in Japan, we will discuss the possible role of De missione in the appearance and production, since the late sixteenth century, of a hybrid pictorial corpus of cosmographic images depicted by Japanese painters on folding screens (the so-called sekai chizu byōbu, or ‘world map’ folding screens), in particular of those of the Jōtoku-ji type, displaying the sea routes of circumnavigation of the whole globe.
Simão Sólis (†1631), cristão-novo: entre justiça humana e justiça divina
Authors: Jacquinet Maria Luísa
Published: December 2022

Em 31 de janeiro de 1631, Simão Pires Sólis, cristão-novo português, era sentenciado à morte de fogueira, acusado da profanação da Igreja de Santa Engrácia, em Lisboa. A condenação, que desde o início suscitara múltiplas e firmes reservas, viria a revelar-se injusta. Mas as circunstâncias político-religiosas da época fizeram de Sólis o réu ideal para dirimir o crime e aplacar a indignação geral. Propõe-se o presente artigo desvelar o caráter circunstancial da condenação e analisar o processo de construção da figura do «herege» no quadro de uma teodiceia escatológica para a qual concorre a justiça terrestre.
Roberto Bolaño e o infinito desdobramento do autor
Authors: Sousa Ana Rita
Published: December 2022

Este artigo pretende desdobrar a dimensão meta-literária da obra de Roberto Bolaño (1953-2003) em dois percursos paralelos trilhados nos seus múltiplos livros e que se encontram na personagem singular de Benno von Archimboldi, escritor consagrado de identidade desconhecida que une as diferentes partes de 2666. Neste sentido, procura-se numa primeira parte elencar e problematizar alguns dos tópicos tematizados por Bolaño dentro do campo literário e que serão capitais para a estrutura narrativa da sua obra magna. Num segundo momento, acompanha-se o percurso de Arturo Belano, alter-ego do autor e personagem fundamental para a compreensão da sua obra. Por último, analisa-se como estes dois percursos se confrontam e se consolidam na figura de Archimboldi, não só a nível temático mas igualmente ao nível do dispositivo narrativo.
Érudition, oubli, affection. Les régimes expographiques des objets de la synagogue de Tomar (1920-2020)
Authors: Isnart Cyril
Published: December 2022

Cet article étudie la vie des collections d’une synagogue-musée consacrée aux Juifs portugais dans la ville de Tomar entre 1920 et 2020. Il s’appuie sur une enquête historique et ethnographique qui suit le parcours des collections exposées, retirées, cachées ou remplacées au cours de la vie du programme muséographique. L’enquête permet de comprendre comment des objets sont choisis pour signifier et matérialiser les avanies historiques de la population affiliée au judaïsme dans un pays qui a reçu, exclu, protégé et exterminé des personnes de confession juive tout au long de son histoire. Tout comme le destin des Juifs portugais eux-mêmes, les parcours des objets exposés dans l’ancienne synagogue de Tomar sont marqués par des effacements, des mises en lumière, des destructions, des éclipses, des (ré)inventions. L’article utilise le concept de régime expographique, dont les trois déclinaisons (érudition, oubli, affection) correspondent à trois périodes distinctes. En suivant pendant un siècle le parcours des objets qui ont constitué les collections de la synagogue-musée de Tomar, cet article se propose de mieux comprendre comment un passé religieux et historique, dont les traces ont été systématiquement effacées, a pu être mis en exposition dans le cadre d’un musée national en soulignant la pluralité des régimes d’exposition et de la nature des collections elles-mêmes. Il permet également de poser un regard sur la complémentarité entre la matérialité d’un monument religieux et celle des collections d’objets de dévotion, dont on active la nature religieuse de façon contrastée, entre le témoignage historique de la présence juive au Portugal (érudition), l’effacement de la présence d’une altérité religieuse historique (oubli) et la construction d’une matérialité dévotionnelle affective (affection). Cet article contribue aussi à réfléchir à ce qu’« exposer des objets religieux » veut dire, en montrant comment le choix des objets implique des lectures différentes du passé. Il pose finalement, dans la lignée des études de la mémoire et du patrimoine religieux la question de la nature du religieux qui se transmet à travers les dispositifs patrimoniaux.
Les musées d’art sacré de Dijon et de Saint-Mihiel : va-et-vient entre collection et usage liturgique
Authors: Le Calvé Léa
Published: December 2022

Les musées d’art sacré de Dijon (Côte-d’Or) et de Saint-Mihiel (Meuse), labellisés « Musées de France », participent à la préservation et à la valorisation du patrimoine religieux de leur département. Ils accueillent notamment des objets en dépôt qui conservent leur propriétaire et leur affectation cultuelle. Les mises en exposition témoignent d’une volonté de restituer les sens et usages religieux tout en mettant en avant d’autres aspects des artefacts. Si le Musée d’art sacré de Saint-Mihiel invite à la contemplation des œuvres, celui de Dijon mêle les collections à l’histoire du lieu. La vie liturgique de trois objets de ces institutions a perduré malgré leur dépôt. Ces cas spécifiques permettent de réfléchir au rapport entre les statuts muséal et cultuel, et attestent des interpénétrations entre les différents systèmes de valeurs.
La mise en exposition au Musée du Hiéron ou l’écriture palimpseste du religieux
Authors: Dufour Stéphane
Published: December 2022

En 1894, Alexis de Sarachaga inaugure son musée, le Musée eucharistique du Hiéron, situé à Paray-le-Monial (dans le sud de la Bourgogne), dont le projet était de créer un lieu d’exposition avec l’ambition théologico-politique de réaffirmer l’idéal théocratique médiéval de la chrétienté contre le modernisme et le profond mouvement de sécularisation de la fin du xixe siècle en France. Pour ce faire, le fondateur consacra une grande partie de sa fortune à l’acquisition d’objets religieux ayant trait au Sacré-Cœur de Jésus et à l’eucharistie, ainsi qu’à la construction d’un bâtiment conçu tout à la fois comme un monument, un temple et un musée. Suite à une période de déshérence du musée, un profond réaménagement est engagé à partir de 2000. Des objets qui avaient été agencés pour soutenir un message théologique se trouvent ré-agencés dans une exposition permanente à vocation culturelle et didactique dans un espace qui conserve nombre de décors et d’ornements originaux.Cette contribution voudrait questionner cette reconfiguration du Musée du Hiéron qui se réalise à l’intérieur de ses propres murs et à partir de la collection initiale. Il s’agit d’analyser le réemploi d’un lieu et d’objets religieux qui, combinés avec d’autres expôts et artefacts plus récents, participent d’un nouveau discours sur le religieux et se voient, par là même, affectés d’une autre signification. On émettra l’idée en forme d’hypothèse que le réemploi dans une nouvelle mise en exposition d’objets ayant déjà servi à signifier une certaine vision de l’eucharistie et du catholicisme ne se réalise pas sans reste ni effet mémoire mais prolonge quelque chose de l’ancien discours théologique dans le nouveau discours.
La carrière patrimoniale d’une mosaïque portative byzantine
Authors: Seraïdari Katerina
Published: December 2022

L’article raconte deux histoires parallèles : celle d’une icône athonite du xive siècle qui se trouva en 1894 dans la collection privée d’un diplomate russe avant d’être acquise par le Musée de Dumbarton Oaks en 1954 ; et celle de l’émergence d’un nouvel objet d’étude dans le domaine de l’art byzantin à partir de la fin du xixe siècle, alors que ces pièces (pour la première fois étudiée systématiquement) sont de plus en plus convoitées par les collectionneurs. Il examine ainsi la manière dont un type d’objet (les « petits tableaux mosaïques portatifs ») fut identifié et nommé à la fin du xixe siècle. L’effort de constituer cette typologie fut marqué par la production de listes énumérant les miniatures byzantines qui avaient survécu au passage du temps. Les inventaires révélèrent la grande rareté de ces pièces, qui avaient été déjà très recherchées par les collectionneurs italiens pendant la Renaissance. L’article suit, plus précisément, le parcours biographique d’une de ces mosaïques qui, après des siècles d’immobilisation dans le trésor du monastère de Vatopedi, connut un certain nombre de déplacements. Son changement de statut (d’objet cultuel à objet muséographique), les conditions de sa circulation, ainsi que les différentes formes d’échange dans lesquelles elle fut impliquée (dons mais aussi achats), révèlent une corrélation avec le développement d’études archéologiques autour des mosaïques portatives. L’articulation entre ces deux histoires montre que le processus d’organisation des savoirs peut avoir un effet sur le marché de l’art et des antiquités.
Les territoires ruraux à l’épreuve de la transition mobilitaire. Conflits et cooperations dans un système d’acteurs en transformation
Authors: Flipo Aurore , Ortar Nathalie
Published: December 2022

Catégorie d’action publique désormais classique en milieu urbain, la mobilité durable s’est instituée récemment comme nouvel objet de politique publique en milieu rural. À partir d’études de cas menés sur deux territoires ruraux en Drôme et en Ardèche au cours des discussions entourant l’adoption de la compétence mobilité par les communautés de communes, cet article se propose d’analyser les réseaux d’acteurs ayant investi le champ de la mobilité durable afin de mettre en évidence la manière dont les territoires ruraux s’emparent de cette question et se structurent, ainsi que la façon dont ils partagent (ou non) leurs référentiels d’action, leurs valeurs et leurs perceptions. La recherche met en évidence l’importance des coopérations qui sont rendues nécessaires par l’existence d’une gouvernance complexe et multiscalaire, mais aussi des controverses et des dissensus qui traversent les relations entre acteurs.
Resilience and Development: Complement, Substitute or Stopgap Solution?
Authors: Ancey Véronique , Pesche Denis , Daviron Benoît
Published: December 2022

What is the political function of the ubiquitous term “resilience” in today’s development aid? This article analyses the discourse of some aid programmes and projects, drawing on 15 years of empirical research on the Sahelian pastoral populations, who today are a symbol of resilience. It shows how the notion of resilience conveys compassionate and security meanings characteristic of a neoliberal policy, resulting in the weakening of public policies. Beyond an alternative between rhetoric and innovation, the use of this notion applied to social groups fine-tunes the ideological steering setting the course of development policy since the 1980s. This article questions the originality of resilience-building projects at local level and the relevance of this notion in the social field.
Review for Region Localization in Large-Scale Optical Remote Sensing Images
Authors: Yin Shoulin , Teng Lin
Published: December 2022

For the massive large-scale visible image data obtained by satellite, unmanned aerial vehicles, and other reconnaissance platforms, if only relying on manual visual interpretation, there will be problems such as heavy workload, low efficiency, high repeatability, strong subjectivity, and high cost, which cannot meet the demand of modern society for efficient information. Therefore, in order to improve work efficiency, it is necessary to study the rapid automatic region localization in large-scale remote sensing images. That will play an important role in change detection, temperature retrieval, and other files. The development and present situation of the region localization algorithms are analyzed. This paper summarizes the development, improvement, and deficiency of the traditional algorithm, as well as the difficulties and challenges. And the authors make a comparison to the deep learning-based methods. Finally, a possible development direction is prospected.
Factors Associated with Prehospital Delay in Patients with Acute Stroke in South India
Authors: Revathi S , Kavitha MS , Shankar V
Published: December 2022

Background:

Early hospital presentation is critical in the management of acute ischemic stroke. The effectiveness of stroke treatment is highly dependent on the amount of time lapsed between onset of symptoms and treatment. This study was aimed to identify the factors associated with prehospital delay in patients with acute stroke.

Material and Methods:

A cross-sectional descriptive study was conducted in Sri Ramachandra University Hospital, India. A total of 210 patients hospitalized in the stroke unit were included. Patients’ data were obtained by interviewing the patient and/or accompanying family member and by reviewing their medical records using a standard questionnaire. Associations were determined between prehospital delay (≥4.5 h) and variables of interest by using univariate and multivariate logistic regression analyses.

Results:

The prehospital delay was observed in 154 patients (73.3%) and the median prehospital delay was 11.30 h. The following are the factors significantly (P < 0.05) attributed for the delay in presenting to the hospital: contextual factors like using public transport (bus), taxi, time of onset of symptoms, 7 pm–3 am; family history of stroke, perceived cognitive and behavioral factors like, wishing or praying for the symptoms to subside on its own, hesitation to travel due to long distance, delay in arranging transport, and arranging money for admission and wasting time by shopping for general practitioners, nursing homes, and hospitals. The presence of stroke symptom, headache, significantly decreased the prehospital delay.

Conclusions:

Prehospital delay is high in South India and influenced by clinical, contextual, and cognitive/behavioral factors.
Utility of F-18 Fluorodeoxyglucose Positron Emission Tomography - Computed Tomography in Primary Thyroid Lymphoma
Authors: Singh Vijay , Mishra Ayush , Kalimuthu Lokeshwaran , Ora Manish , Nazar Aftab Hasan , Gambhir Sanjay
Published: December 2022

Primary thyroid lymphoma (PTL) is an uncommon malignancy. The majority of PTLs are non-Hodgkin's lymphoma. Fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) is the state-of-the-art imaging in lymphoma and plays a pivotal role in staging, follow-up, and treatment decisions. There is good evidence that it performs well in a wide variety of nodal and extranodal lymphomas (ENL). However, the data are scarce on its usefulness in rare ENL. Herein, we describe four cases of PTLs and a brief review of the literature. FDG PET/CT was performed at baseline to assess the disease status and response to treatment. This case series highlights the varied appearance of PTL and response to treatment. It establishes the importance of FDG PET/CT in the personalized management of PTL.
Отказоустойчивая разделимость некоторых графов выпуклых многогранников
Authors: Sharma Sunny Kumar , Raza Hassan , Bhat Vijay Kumar
Published: December 2022

Отказоустойчивая разделимость является расширением понятия разделяющих метрик в графах с несколькими приложениями в интеллектуальных системах, например, при оптимизации сетей, управлении роботами и сетями датчиков. Графы выпуклых многогранников, обладающих симметрией относительно поворотов, используются в интеллектуальных сетях, так как обеспечивают одинаковую скорость преобразования данных для всех узлов. Разделяющее множество - это такое упорядоченное множество $\mathbb{W}$ вершин связного графа $G$, что вектор расстояний до всех вершин из $\mathbb{W}$ однозначно определяет каждую вершину графа $G$. Минимальная мощность разделяющего множества $G$ называется метрической размерностью графа $G$. Если $\mathbb{W}\setminus \rho$ также является разделяющим множеством для каждого $\rho\in\mathbb{W}$, то $\mathbb{W}$ называется отказоустойчивым разделяющим множеством. Отказоустойчивая метрическая размерность $G$ - это минимальная мощность такого множества $\mathbb{W}$. Исследованы метрическая размерность и отказоустойчивая метрическая размерность для трех семейств графов выпуклых многогранников. Основные результаты показывают, что эти три семейства имеют постоянные отказоустойчивые структуры разделимости.
Structural framework and deformation episodes in the igarra schist belt, southwestern nigeria
Authors: Omang B. O. , Asinya E. A. , E. Udinmwen  , Oyetade O. P.
Published: December 2022

The structural framework of the Igarra schist belt consists of brittle (mainly fractures) and ductile (foliation, cleavage, folds, lineations, strain markers) structures. The geometry of these structures reveals two major occurrences of transpressional deformation affected the schist belt. These are an older dominantly ductile deformation with NW–SE λ1 which developed foliations, cleavage, folds, and mineral/stretching lineations deforming only the metasediments and a younger brittle–ductile, E-W tectonic shortening deformation which closed deformations in the Igarra schist belt, deforming both the metasediments and granitoids, producing almost all the brittle structures in the belt. Minor fracture trends which are not associated with any of the major episodes of deformation and E-W transposition foliation in marble and gneisses constitute a relic of an unconfirmed possibly older episode of deformation. Ductile and semi-brittle shear zones in the Igarra schist belt are few and usually occur on small scale (outcrop scale), hence, they do not constitute a major episode of deformation. Mineralizations in the Igarra schist belt are pegmatite and quartz which are emplaced mainly in fractures with industrial minerals like marbles.
Reservoir evaluation of sand beds in sapele field, onshore niger delta
Authors: J. E. Emudianughe , O. M. Ekechikwe
Published: December 2022

The Sand beds of the Sapele field have been evaluated to ascertain the viability of the field for hydrocarbon development using integration of the structural play and petrophysical indices. Pay sands were delineated using the quick look approach. A seismic horizon of interest was picked using a well control measure. The structural play reveal three major faults responsible for hydrocarbon migration and entrapment mechanisms which contributed to a three-way closure in the area. Litho-stratigraphic correlation revealed repetitive gamma-ray signatures across the wells, an indication of active fault zone, and this defines the complexity of the Sapele field. The gamma-ray signatures infer a clastic marine settings when compare with standard log motifs. Petrophysical results reveal very good pore volumes of over 20% with 0ver 15% effective and an excellent degree to transmit fluid (over 1000mD). The high hydrocarbon saturation of over 70% infer good producibility of the field. The results has extensively showed the viability of the Sapele field for good field development.
Geophysical and geostatistical reserve estimates of migmatite-gneiss deposits from parts of southwestern nigeria
Authors: Omowumi Ademila
Published: December 2022

The plan for durable rock base road construction and other civil engineering works necessitated this study to establish the thickness and quantify migmatite-gneiss deposits. This intends to facilitate its exploitation and proffer specific details for diverse applications. Comprehensive geological field mapping, laboratory density measurements and geoelectrical resistivity were employed for the resource quantification. The extent of migmatite-gneiss deposits and its contacts with other rock types were identified. Seventeen (17) fresh migmatite-gneiss rock samples collected from different rock outcrops were taken to the laboratory for measurement of their density. Schlumberger vertical electrical sounding (VES) technique with a total of forty-two sounding stations were employed across the area with electrode spread (AB/2) ranging 1 - 200 m. The average density of the deposits is 2.70 ± 0.10 g/cm3. Three to five geologic layers characterized the area subsurface sequence. Thick fractured rock layer across the area would facilitate the exploitation of the deposits as construction aggregates. Basement topographical highs at northeastern, northwestern and southeastern parts serve as the best zones viable for mining. The basement resistivity (> 3000 Ωm), resistivity contrast, reflection coefficient values and high transverse layer resistivity (ρT) (> 500 Ωm) corroborate the freshness of the deposits. The average thickness of the deposit is 29.3 m, though, thicker at northeastern and northwestern parts of the area where the deposit is fresh and less weathered. The study area occupies a total area of 71,300,000 m2 with volume of the deposits calculated as 2,089,090,000 m3. Distantly-spaced data points of the variogram reveal high degree of variability with respect to locations. The estimated migmatite-gneiss resource tonnage of 5,640,543,000 tonnes shows prospects for sustainable large scale mining as construction aggregates and diverse applications of economic purposes using open pit coupled with underground mining for deeper sections of the migmatite-gneiss deposit.

Published: December 2022

Microorganisms such as fungi can fragment carbon compounds by hydrolytic enzymes. The filamentous fungus, Aspergillus niger is now mostly considered because of its ubiquitous nature, non-fastidious nutritional requirements and it is classified generally as safe. This study was aimed at the production of cellulosic enzymes by A. niger and hydrolytic degradation of cellulosic materials by these enzymes. Standard methods were employed in soil samples collection, isolation of A. niger from the soils and their screening for enzyme production. Results showed that the A. niger isolates exhibited considerable activities of degrading and hydrolyzing cellulose in the agar media. The highest FPase, cellulase and xylanase activities were obtained from white saw dust with concentrations of 0.4059 U/ml, 0.7695U/ml and 1.3488 U/ml respectively. Also, results showed high enzyme activity at pH 6 (0.52U/ml) and temperature of 30ºC (0.72U/ml). Acid hydrolysis of the cellulosic substrates resulted to the release of 6.5% total sugar from white sawdust. The findings of this study revealed that the enzymes produced by A. niger hydrolyzed cellulosic materials but acid is more efficient than the enzymes in the hydrolysis and release of total sugar from cellulosic materials. This study recommends that cellulolytic enzymes used in the industries should be produced locally using filamentous fungus such as Aspergillus niger and cellulosic materials as carbon source.

The effect of ethanol leaf extract of Alchornea cordifolia on some biochemical parameters in phenyl hydrazine-induced anaemic Wistar rats was studied. A total of thirty-six (36) Wistar rats weighing 95-200 g were selected for this study and randomly divided into six groups of six animals per group. Group A (normal control), group B (negative or anaemic) control, group C (standard), group D, E and F (treated groups). Animals in groups B, C, D, E and F were induced with anaemia via intraperitoneal (I.P.) injection of 10mg/kg body weight phenyl hydrazine (PHZ) for 3 days and group A received distilled water in place of the PHZ for the same duration. After the induction, group A and B rats received oral administration 0.9w/v normal saline solution while groups C, D, E and F received oral administration of enzoron (10mg/kg.bwt), 100, 200 and 400 mg/kg.bwt of extract respectively for 14 days. The percentage yield of the extract was determined to be 18%. Phytochemical screening revealed the presence of saponins, carbohydrates, protein, alkaloids, phytosterols, phynols, flavonoids and glycosides at varying concentrations.A dose of 5000mg/kg. bwt was found to be safe in the LD50 study of the extract. The oral administration of the extract showed a significantly  (p<0.05) level of  total protein (TP)  ,packed cell volume (PCV), haemoglobin (Hb) and red blood cells (RBCs) of the animals in treated groups  compared to those of the animals in anaemic groups.The aspartate transaminase (AST),alanine transaminase (ALT)and total bilirubin (TB)were significantly (p<0.05)  lowered in the extract treated groups than  in the anaemic non-treated groups. There was a no-significant decrease (p>0.05) in the serum urea, creatinine, Na+ ,K+  and ,Cl­- of animals in the extract treated groups when  compared to both the normal and standard control . The histology of the spleen revealed the regeneration of damaged cells in extract treated groups unlike that of the anaemic non-treated groups which showed distorted architecture. The study suggests that treatment with Achornea cordifolia leaf extract in phenyl hydrazine induced anaemia enhances anti- anaemic and hepatoprotective effect possibly due to both its anti-inflammatory and antioxidant properties.

Due to the high rate of suicide all over the world resulting in about 800,000 people dying by suicide each year. The instances where suicide victims constantly publish suicide messages deliberately to express their feelings on social media, there is need to address suicide issues, and how suicide can be prevented. Therefore, as a solution to this, there is need to create a model that classifies these users" social media posts and identify users with suicidal ideations, so as to prevent future suicide cases by getting the identified users the necessary help needed. The study adopted a binary classification of a suicide-related tweet with respect to age 15 up till 29 years, on a document-level basis. A machine learning approach was employed to solve the problem of tweet classification and predictions. The dataset was generated from a Twitter API.

It was observed that suicidal issues are rampant among the young adult, which need urgent attention. The paper recommended that timely intervention should be provided so as to reduce suicidal victims and preserve the future of young adults.

Authors: Spólita J. I. , Balsa J. , Brusco V.
Published: December 2022

This article analyzes the extent to which the pandemic, the confinement situation, the evaluation of the policies and attitudes of the leaders affected the subjectivities of Argentine citizens. Special attention is paid to the influence of the strong political polarization that existed previously and, also, to the ways in which the pandemic itself could have influenced political subjectivities. In addition, we have studied the reflections that, in a pandemic context, the majority of the population made about the meaning of their lives, also relating them to their political orientations. To carry out these analyses, a series of surveys were carried out throughout the year 2021 and a sample of semi-structured interviews in the months of April and May of that same year.

Authors: Fiquepron M. R.
Published: December 2022

Since its inception as a global pandemic, COVID-19 has been the subject of multiple appropriations around the world. With the possibility of writing and sharing information open due to current technological developments and digital media, a series of publications focused on reflecting on the impact of the pandemic around the world circulated during the first months of 2020.

The aim of this article is to analyze these publications, taking them as a valuable input to delve into the reflections that, from culture and social sciences, emerged on the pandemic. What can these articles show us, already more than two years after being published? What were the main ideas, concerns and diagnoses? Beyond these questions, we are also interested in investigating the construction of a network of meanings and notions that began to be associated with the disease and that, in its pandemic context, we believe is highly relevant to understanding the meanings that were incorporated into this new virus as it spread across the globe.

Authors: Hegde Chitrakara , Ribeiro Rahul
Published: December 2022

Hydrophobic membranes prepared using Poly (tetrafluoroethylene) (PTFE) along with Poly (1,4-phenylene ether ether-sulfone) and zinc oxide nanoparticle was used in membrane distillation. To examine seawater purification, prepared polymeric membranes were evaluated, tested, and used in a lab-scale direct contact membrane distillation arrangement. These membranes which are synthesized using the electrospinning method have good mechanical and thermal stability. To understand prepared membranes’ desalination performance, the physicochemical properties of the seawater were analyzed before and after membrane distillation. The salt rejection remained at 99% and the highest energy efficiency of the system observed is 67.3%.

Authors: Fu C. K. , Fang Y. , Yang C. Y. , Chen C. G. , Wang L. X.
Published: December 2022

This paper mainly studies the adsorption of C3N4 on a series of heavy metals and focuses on the adsorption performance of C3N4 on Nd and Th. The main conclusions are as follows: Through the use of the thermal stripping method and melamine as the raw material, C3N4 was obtained at a lower cost, with superior adsorption performance. Through SEM-EDS, TEM, and other characterization analyses, the results show that C3N4 has a clear multilayer sheet structure, and the surface of the material is more uniformly dispersed. The maximum adsorption capacity of C3N4 for Th is 86.6 mg.g-1, and the maximum adsorption capacity for Nd is 60.1 mg.g-1. The kinetic model is also used for fitting, and the results showed that the kinetic of the adsorption was in line with the pseudo-second-order model, indicating that the adsorption was chemical interaction. After C3N4 adsorbed heavy metal elements, it was characterized by SEM-EDS, TEM, UHRTEM, and AFM. The results showed that a variety of heavy metal ions can be adsorbed by C3N4, which proved that C3N4 has good adsorption performance. Due to factors such as metal particle size, the adsorption of C3N4 on heavy metal elements is different.

In Indonesia, the pest Thrips parvispinus Karny is a major problem for red chili plants. Most pest control techniques rely on synthetic pesticides, resulting in environmental degradation, the extinction of natural enemies, and the emergence and resilience of a variety of different pests. The aim of this study is to determine the impact of a 25% Imidacloprid insecticide on population density and the proportion of infestations and natural enemies in the field. A randomized block design with 5 treatments and 5 replications was utilized in this field investigation. Plant samples were collected in a “U-shaped” pattern. According to the findings, a 25% Imidacloprid pesticide had a significant influence on population density and T. parvispinus attack on red chili plants. Moderate damage was caused by T. parvispinus’ infestation on red chili plants using 50-200 L.ha-1 25 % Imidacloprid pesticide. Furthermore, a 25 % Imidacloprid insecticide applied at a rate of 100 L.ha-1 had a significant influence on the population variety and abundance of T. parvispinus natural enemies. A 25 % Imidacloprid insecticide dosage increase was shown to have a very strong relationship with a reduction in population density, the proportion of T. parvispinus assault, and the variety and quantity of natural enemies in red chili. Thus, a 25 % Imidacloprid insecticide at a rate of 100 L.ha-1 proved successful in reducing T. parvispinus while remaining safe for natural enemies. Future pest control techniques must still be based on improved field data collection, such as data on pesticide contamination or other anthropogenic chemicals, which may also be used to estimate natural enemy population levels in the field.
