Published: January 2021

The objective of this investigation was to develop formulation of floating matrix tablets of tizanidine HCl to prolong the gastric residence time by using hydroxy propyl methyl cellulose (HPMC K15M) or xanthan gum as sole release retardant and to check the clinical response. The drug-excipients compatibility studies were conducted using DSC and also by visual observation. Incorporation of NaHCO3 in the formulation resulted incompatibility with drug and therefore, the composition was modified by replacing NaHCO3 with CaCO3 in remaining formulations. Floating matrix tablets of tizanidine were developed by direct compression method and the developed ten formulations exhibited satisfactory physicochemical characteristics and in-vitro buoyancy. Formulation (F9) was selected as optimized formulation based on physicochemical characters, in-vitro buoyancy and drug release, and was used in in-vivo radiographic studies in human volunteers by incorporating BaSO4. In radiographic studies, the gastric retention time of floating tablets was found to be 4 ± 0.86 h (n=3). Optimized floating tablets (F9) were used to know the clinical effects in patients suffering from spasticity under the observation of clinician. The optimized tizanidine HCl floating matrix tablets were developed and found to have gastric retention behaviour in stomach and further were found to have good clinical effects in patients suffering from spasticity during preliminary clinical studies.

New Challenges to Transboundary Unitization in the Gulf of Mexico
Authors: Olson Isaac
Published: February 2021

In the last two decades, the search for untapped oil reserves led to many innovations in oil and gas exploration. As new technology continues to open new horizons, oil companies are increasingly able to drill at deeper ocean depths to tap offshore reserves. Offshore drilling poses problems where oil reserves hundreds of miles from shore cross an international boundary line. While American courts typically apply the rule of capture to determine who owns the subsoil resources, international law requires countries to work together to maximize the efficient, safe extraction of the resources. In 2012, the United States and Mexico drafted a treaty that would govern the unitization of an offshore transboundary oil field. Today, Mexico’s energy laws are very different. A new administration threatens to unravel recent liberal reforms, and the United States has become more hostile to Chinese investment in the region. With these political challenges in mind, the treaty is very vague on critical issues, particularly its dispute resolution clause, which the United States and Mexico must strengthen if the treaty is to be effective and shared transboundary resources develop efficiently to the benefit of both nations. The treaty creates a body called the Joint Commission to create much of the treaty’s policy and procedure. In order to maintain good relations and a healthy energy sector, the Joint Commission needs to create subsidiary committees subject to its control and comprised of various experts to ensure the treaty is implemented impartially.
When Home is a Living Hell
Authors: Pricer Sarah
Published: February 2021

Low-income women experience a nightmarish victimization when they are sexually harassed by landlords in their homes, homes many are desperate to keep. The staggering lack of data on this issue means laws and courts have been slow to address this phenomenon. Although courts have relied primarily on a Title VII employment-based sexual harassment framework to address this issue, it does not go far enough in protecting women in their homes. The home and the workplace are inherently different and thus require a different legal approach to redress the issue.

This comment examines sexual harassment in housing and why Texas women are particularly susceptible to it. This comment further advocates for courts to look to existing housing law and expand application of the Fair Housing Act’s disparate impact approach in addressing sexual harassment in housing to low-income women. Low- income women of color are the primary victims of sexual harassment in housing; this permits a gender and race-based disparate impact theory as another framework through which courts may craft a solution, though it too has its shortcomings. Additional measures, such as the expansion of federal law to cover sexual harassment in housing, and state-level policy changes that would penalize deviant landlords and property owners, would serve to empower and strengthen low- income Texas women without leaving entire subsections of the population behind. This comment further argues that holistic community-level action is not only desirable, but necessary to educate communities and provide low-income women increased access to the courts. Finally, the above suggested measures will do little to change the outlook for low-income women if states fail to address the underlying issue that makes the need for housing so desperate: the affordable housing crisis.

On the basis of experimental studies in the field and on polygon, the features of the detonation of mixed explosive charges on various types of ammonium nitrate with energy additives during pneumatic load-ing are revealed. It has been established that when using porous grades of nitrate, the addition of alu-minum powders differently dispersed leads to a decrease in detonation parameters due to the peculiari-ties of aluminum oxidation at the front of the detonation wave and does not provide the theoretically expected increase in the energy of the explosion. The use of high-quality fine-grained porous nitrate in the ANFO mixtures allows obtaining the higher explosive characteristics of the mixtures. The supple-ment of energy additives in the form of aluminum powders does not increase the explosive characteris-tics of the mixture.

Published: February 2021

This article is devoted to the consideration the features of world-class scientific and educational centers. The first five world-class SECs in 2019 as part of the national project “Science”. Until 2024, it is planned to create at least 15 world-class scientific and educational centers. The need to create and develop a world-class SEC is explained by the possibility of generating more qualitatively new scientific ideas that will be created within the framework of centers and universities and bringing innovative ideas to the market with the help of interested enterprises. In the future, it is assumed that a number of ideas being developed will correspond to the world level. Ideas related to the socio-economic development of the region will also be of great importance. Cooperation between universities, scientific organizations, enterprises and other stakeholders within the framework of the center will benefit all participants in cooperation. Currently, SECs have been created in five regions – in the Belgorod region, Kemerovo region, Nizhny Novgorod region, Perm Territory and Tyumen region. The specialization of the centers was chosen in accordance with the already formed priority areas of the regions. The activities of the world-class SEC are focused on improving the quality of education, developing networking between representatives of science, education and business and commercializing innovation. The article defines a number of problems that impede the development of worldclass scientific and educational centers.

On the issue of socialization of eduction under late capitalism
Authors:   Center for Institutions of Socio Economic Development of the Institute of Economics of the Russian Academy of Sciences, Yakovleva Natalia G.
Published: February 2021

The article substantiates the need for socialization of education at the stage of late capitalism and the transition to a new quality of economy and society – noonomy. The social failure of the neoliberal socio-economic policy of the state led to the desocialization of the economy and the marketization of the social sphere. The marketization of education has resulted in regressive trends – commercialization, bureaucratization and managerialism. Qualitative changes in the economy and society associated with the transition to a new technological order and the creative revolution relate not only to the industry, but also directly to the individual and the essence of his work. This requires an accessible education for all and through life. This requires the socialization of education and its transformation towards an egalitarian model.

Experimental works for analysing flow behaviour inside human trachea has become continuous problem as the model used to study cannot imitate the real geometry of human trachea structure. As the technology develop, Rapid Prototyping (RP) become more useful in constructing the 3D model that has complexity in their geometries. RP not only offer several technologies in developing the 3D model, but also varies type of materials that can be used to manufacture the 3D model. In this study, RP technique was chosen to develop the 3D model of human trachea to do the Particle Image Velocimetry (PIV) experimental works. Material used was Vero Clear due to PIV need a model that transparent so that visualization on flow inside the model can be seen and the velocity magnitude can be capture. The geometry was adapted from 60 years old trachea patient where the images of trachea was taken by using CT-scan. MIMICS software was used to extracted the images before reconstruct the trachea into 3D model. Velocity distribution was visualized and the magnitude were taken at both left and right bronchi. From the analysis, it concluded that the distribution of airflow to the second generation of trachea was 60:40 to right and left bronchi. It follows the rules as the right bronchi need to supply more air to the right lung compared to left as the volume of right lung bigger that left lung.

Authors: Burgstaller Stephan , Leeb Christoph , Ringler Max , Gollmann Günter
Published: February 2021

Understanding population dynamics is vital in amphibian conservation. To compare demography and movements, we conducted a capture-recapture study over three spring seasons in two populations ofSalamandra salamandrain the Vienna Woods. The study sites differ in topography, vegetation, and the type of breeding waters. Population density in a beech forest traversed by a stream was more than twice as high as in an oak-hornbeam forest with temporary pools. Movement distances were on average higher at the latter site whereas home range estimates were similar for both sites. The sexes did not differ significantly in the observed movement patterns at either site. Annual apparent survival was mostly high (~0.85), but the estimate for females from the low-density site was lower (~0.60), indicating a higher rate of emigration or mortality.
Une idole de la vérité, une idole de l’obscurité
Authors: Thirouin Laurent
Published: February 2021

Se faire une idole de la vérité ? La formule du fragment 755 est suffisamment paradoxale et scandaleuse pour avoir retenu la critique pascalienne. La présente étude fait le point sur les diverses interprétations proposées, et s’attarde sur la deuxième partie de la pensée où, à une idolâtrie de la vérité est comparée une idolâtrie de l’obscurité. Quel est le lien exact entre les deux temps du fr. 755 ? On interprète habituellement le terme d’obscurité, comme appartenant au lexique de la vérité. Mais l’examen attentif du texte, et du lexique classique, prouve que cette hypothèse n’est pas recevable. Ce n’est pas la question de la vérité, mais celle de l’idolâtrie qui fait le vrai sujet de cette pensée.
Jacques Le Brun (1931-2020). Critique textuelle et histoire de la spiritualité
Authors: Trémolières François
Published: February 2021

Jacques Le Brun appartient à une génération d’historiens du catholicisme qui a déplacé l’intérêt de l’histoire de l’Église, ou de l’histoire des doctrines, à une histoire des croyances. Il l’a fait en privilégiant les écrits spirituels, y compris et d’abord ceux de grands auteurs : Bossuet, Fénelon. Dans les objets que se donne ainsi l’histoire religieuse, tel le « pur amour » durant la querelle du quiétisme, il a découvert un « impossible à penser » – la discipline historique rencontrant un questionnement d’ordre anthropologique et le travail exégétique s’enrichissant d’une attention à la lettre d’ordre psychanalytique.
Marc Fumaroli (1932-2020), le dernier patricien de la République des Lettres
Authors: Nativel Colette

Penseur subtil et engagé, amoureux des Lettres et de la Beauté, Marc Fumaroli, de l’Académie Française, a profondément renouvelé l’histoire littéraire et l’histoire de l’art de l’époque moderne en élaborant une démarche appropriée à son objet. S’appuyant sur une fabuleuse érudition, replaçant les œuvres dans leur contexte de création et utilisant les outils intellectuels qui avaient été ceux de leurs créateurs et de leurs destinataires, en particulier la rhétorique, il a renouvelé la tradition historiographique en mêlant différentes approches – littéraire, historique, sociale, politique, philosophique, religieuse… Marc Fumaroli voulait faire partager à ses contemporains le bonheur que lui avaient donné la littérature et les arts. Homme de progrès, même si c’est dans la tradition qu’il trouvait les éléments capables de nourrir ce progrès, il avait une vision lucide de l’histoire et du monde contemporain, souvent sombre, certes, mais intimement pénétrée de l’idée que l’action permettait de lutter contre la médiocrité ambiante.
A survey of near-death experiences in Brazil: exploring socio-demographic characteristics and relationship to psychopathology and mystical experiences

Published: February 2021

Nous présentons les résultats d’une enquête portant sur le pourcentage d’expériences de mort imminente dans un échantillon brésilien et leur relation avec les caractéristiques sociodémographiques, la psychopathologie et les expériences mystiques. 350 participants (80,3 % de femmes d’âge moyen = 37,43 ans, écart-type = 12,80, minimum = 18 ans, maximum = 81 ans) ont répondu à un sondage en ligne sur les conséquences psychologiques d’événements menaçant le pronostic vital, notamment l’échelle de NDE de Greyson et l’échelle de mysticisme de Hood (ou Échelle M). Les sondés ont été divisés en trois groupes : 1) ceux qui n’ont pas signalé d’événement significatif mettant leur vie en danger ; 2) ceux qui ont signalé une situation mettant leur vie en danger, mais qui n’ont pas obtenu un score supérieur ou égal à 7 sur l’échelle de NDE ; et 3) ceux qui ont déclaré un événement menaçant le pronostic vital et ont obtenu 7 ou plus sur l’échelle de NDE. 14 % de l’échantillon remplissait les critères pour une EMI. Ces derniers ont obtenu des scores significativement plus élevés pour le facteur de mysticisme introverti de l’échelle M. par rapport aux autres groupes, mais aucune différence n’a été constatée pour les autres facteurs et le score total. Cependant, aucune corrélation significative entre les scores NDE et M-Scale n’a pu être établie. Les personnes ayant relaté une EMI étaient significativement plus âgés que les sujets des autres groupes, mais également plus religieux ou spirituels, avec une prépondérance de membres de groupes ésotériques et New age. Aucune différence n’a été trouvée pour les autres variables démographiques et la psychopathologie. Les résultats mettent en évidence certaines caractéristiques possibles des Brésiliens ayant vécu une EMI. Nous espérons que la présente enquête contribuera à la littérature interculturelle sur certaines expériences mystiques et aux frontières de la mort.
Psychopathologie des personnes survivantes
Authors: Damiani Carole
Published: February 2021

Le traumatisme psychique se différencie du deuil par la nature de l’angoisse et des affects dépressifs, par le statut de l’image traumatique et du nécessaire travail d’élaboration psychique. Les effets du traumatisme psychique et ceux du deuil chez les survivants peuvent entrer en conflit et imposent une adaptation thérapeutique au cheminement temporel du sujet. La fonction et l’élaboration de la culpabilité dite « du survivant », peut se révéler moteur ou obstacle à la psychothérapie. Elle ne sera pas évacuée trop rapidement car elle est bien souvent un contrepoids à l’angoisse de néantisation.

Nos sociétés vieillissantes subissent un clivage entre travail palliatif et thanatique qui altère la relation aux soignants. Le cas exemplaire d’une maladie incurable ouvre à l’idée de constituer un corpus de directives anticipées et d’animer des ateliers pédagogiques dès 18 ans.
Discours des origines et pensée politique dans la littérature des XII e et XIII e siècles
Authors: Boutet Dominique
Published: February 2021

Il y a au Moyen Âge plusieurs temps qui font, selon les textes, fonction de temps des origines : origine du monde (référence biblique, mais quelquefois utilisation des mythes gréco-romains de Saturne et de Jupiter, par exemple chez Jean de Meun), origine des trois ordres de la société médiévale et de la relation féodo-vassalique, origine troyenne de plusieurs peuples occidentaux (les Bretons, les Francs, les Danois…), enfin le Christ pris comme point d’origine, en particulier dans les romans du Graal dès la fin du xii e  siècle. Il faut ajouter la référence à Charlemagne, point d’origine glorieux de la stirps Caroli vers lequel Philippe Auguste doit assurer le retour. Cette contribution les examine, dans leurs rapports avec la pensée politique, au travers d’un grand nombre de textes de toute nature, en vers ou en prose, en français ou en latin, textes théoriques, historiographie, romans du Graal et chansons de geste.
Comment écrire une histoire sans origines : Voltaire
Authors: Méricam-Bourdet Myrtille
Published: February 2021

L’étude s’intéresse à la question des origines à partir de l’histoire universelle rédigée par Voltaire, qui se veut en rupture avec la tradition historiographique chrétienne. En refusant des généalogies sujettes à caution, Voltaire cherche plutôt à reconstituer le cheminement possible des faits sociaux et culturels. La démarche, qui n’est pas sans présenter elle aussi des partis pris, lui permet de prendre position dans un certain nombre de débats politiques contemporains.
Désordres dans la lignée : le motif du prince monstrueux au XVIII e siècle, entre science, merveille et politique
Authors: Sempère Emmanuelle
Published: February 2021

La figure du prince monstrueux (ou de la princesse monstrueuse), récurrente dans les contes, est particulièrement exploitée par les conteurs français de la fin du règne de Louis XIV, et jusqu’à la mort de Louis XVI. Cet article envisage l’hypothèse selon laquelle ces « fictions pensantes » font résonner les questionnements savants qui se sont cristallisés au moment de la querelle des monstres dans les années 1730. À partir de quelques contes d’Aulnoy, de Lubert, de Crébillon et de Tiphaigne de La Roche, il montre comment s’est forgé et a circulé un imaginaire du monstre comme corruption de l’origine aux fortes implications politiques.
Definitions in Aristotle’s Politics : State and constitutions
Authors: Rapp Christof
Published: February 2021

Ce texte traite de la définition aristotélicienne de la cité et des diverses constitutions, en Politique , I et III. On soutient ici (1) que la définition de la cité doit être extraite de deux passages du début du traité, (2) que la cité est définie par le but qui lui est propre et (3) que d’importants théorèmes politiques en Politique III se servent de cette définition initiale de la cité comme d’une prémisse. L’objectif ultime de cet article est de contribuer à l’évaluation du rôle que jouent les définitions dans la méthode qui est celle d’Aristote dans sa philosophie morale et politique.
An Infratemporal Meningioma: A Diagnostic Dilemma
Authors: Kulwat Singh Arlinder Kaur , Ali Rofiah , Omar Effat , Hashim Hilwati
Published: January 2021

A 46-year-old male presented with painless, recurrent bilateral ear discharge and an enlarging right temporal swelling. There were no neurological deficits. Imaging revealed an enhancing, soft tissue mass at the right infratemporal region involving the right temporalis muscle with a small, enhancing intradural component and associated hyperostosis of the greater wing of the right sphenoid bone. Tumour debulking of the right temporalis tumour was performed. Tumour invasion of the right temporalis muscle was noted intraoperatively. Histopathological result was consistent with fibrous meningioma WHO Grade 1 involving surgical resection margins. Follow-up MRI revealed residual right temporal extracranial component. Thus, plans were made for a second stage tumour debulking, however at time of writing, surgery had not been performed. This case highlights the differing appearances of the common meningioma occurring extracranially with elaboration of its differential diagnosis and management.
Magnetic Resonance Imaging Appearance of Erythema Nodosum: A Case Report
Authors: Chauhan Ankita , Thomas Richard
Published: January 2021

Erythema nodosum (EN) is the commonest inflammation of the subcutaneous fat tissue (panniculitis). Erythema nodosum (EN) requires an interdisciplinary approach and exclusion of all underlying causes. We present a case of an 18-year-old female with a history of recurrent streptococcal infections over the years, who developed pain and swelling in the left ankle. To evaluate the persistent ankle swelling, the physician ordered a magnetic resonance imaging (MRI) of the left lower extremity. The MRI appearance of EN has not been described in detail in the literature so far.
Innovation dans un projet de télécollaboration orale en intercompréhension : bilan et perspectives du projet IOTT
Authors: Garbarino Sandra , Leone Paola
Published: February 2021

Cet article dresse un bilan d'un projet télécollaboratif d'apprentissage appelé Intercompréhension orale et teletandem (IOTT) développé par l'université Lyon 2 et l'université du Salento. Il montre également le potentiel de la communication synchrone plurilingue assistée par ordinateur au niveau de l'apprentissage dans deux disciplines différentes : un programme d'intercompréhension et un cours de méthodologie d'enseignement des langues étrangères. Après avoir décrit le design pédagogique (les activités déroulées au niveau international et local), les auteures proposent une démarche méthodologique (Cros, 2004) qui permet d'autoévaluer le projet et ses résultats.L'observation des forces et faiblesses du scénario met en évidence les domaines à travers lesquels on peut le comprendre en profondeur, par le biais d'une analyse bottom-up, enrichie d'un focus théorique. Ce bilan a également pour but de valoriser l'innovation de IOTT par rapport aux scénarios et expériences d'enseignement/apprentissage d'intercompréhension et télétandem antérieurs. Le processus d'évaluation vise la transformation et le changement des valeurs et pratiques éducatives et il implique les étudiants de manière active. Leurs retours sont illustrés par les données collectées à partir de questionnaires, journaux réflexifs, enregistrements des sessions télétandem et interviews. L'évaluation de IOTT est finalement effectuée en direction de l'amélioration de son design pédagogique dans le but d'optimiser l'apprentissage dans le cadre de futurs projets télécollaboratifs pour l'éducation plurilingue.
Virus Control in Vaccinated Rhesus Macaques Is Associated with Neutralizing and Capturing Antibodies against the SHIV Challenge Virus but Not with V1V2 Vaccine–Induced Anti-V2 Antibodies Alone

The role of vaccine-induced anti-V2 Abs was tested in three protection experiments in rhesus macaques. In an experiment using immunogens similar to those in the RV144 vaccine trial (Anti-envelope [Env]), nine rhesus macaques were coimmunized with gp16092TH023 DNA and SIV gag and gp120A244 and gp120MN proteins. In two V2-focused experiments (Anti-V2 and Anti-V2 Mucosal), nine macaques in each group were immunized with V1V292TH023 DNA, V1V2A244 and V1V2CasaeA2 proteins, and cyclic V2CaseA2 peptide. DNA and protein immunogens, formulated in Adjuplex, were given at 0, 4, 12, and 20 weeks, followed by intrarectal SHIVBaL.P4 challenges. Peak plasma viral loads (PVL) of 106–107 copies/ml developed in all nine sham controls. Overall, PVL was undetectable in one third of immunized macaques, and two animals tightly controlled the virus with the Anti-V2 Mucosal vaccine strategy. In the Anti-Env study, Abs that captured or neutralized SHIVBaL.P4 inversely correlated with PVL. Conversely, no correlation with PVL was found in the Anti-V2 experiments with nonneutralizing plasma Abs that only captured virus weakly. Titers of Abs against eight V1V2 scaffolds and cyclic V2 peptides were comparable between controllers and noncontrollers as were Ab-dependent cellular cytotoxicity and Ab-dependent cell-mediated virus inhibition activities against SHIV-infected target cells and phagocytosis of gp120-coated beads. The Anti-Env experiment supports the role of vaccine-elicited neutralizing and nonneutralizing Abs in control of PVL. However, the two V2-focused experiments did not support a role for nonneutralizing V2 Abs alone in controlling PVL, as neither Ab-dependent cellular cytotoxicity, Ab-dependent cell-mediated virus inhibition, nor phagocytosis correlated inversely with heterologous SHIVBaL.P4 infection.
Paleoclimatic inferences based on wood growth interruptions in Late Triassic flood deposits from the southernmost Brazilian Gondwana

The goals of this study were to establish patterns in a silicified wood assemblage to depict the evolution patterns of the Triassic paleoclimate in southern Brazilian Gondwana during an interval of global arid to semi-arid climatic context, and the taphonomic process that led to the preservation of the so-called “Petrified Forest”, which is preserved in the central area of the state of Rio Grande do Sul. Analyses were developed with an assemblage of 13 permineralized conifer wood, using standard thin sections, whose anatomical details were studied in transmitted light. Ground-Penetrating Radar was used to obtain information about the depositional characteristics of the site. Main results are: true growth rings are absent in all samples, and the boundaries of the interruption zones are marked by an abrupt decline in cell diameter, but they are not accompanied by a reduction of cell wall thickness. The subsequent reversion to normal tracheid diameter is also abrupt, revealing the return of the previous growing conditions. Ground-penetrating Radar analyses confirmed that the Mata Sequence deposits correspond to a river. The identification of growth interruption zones in a Late Triassic wood assemblage in southernmost Brazilian Gondwana (Paleobotanic Garden of the city of Mata, RS) indicates the presence of tropical, temporarily dry climate conditions, characterized by irregular, short-term environmental disturbances to growth. The taphonomic process was related to a river-channel infilling depositional process, under the influence of high-energy flood events that dragged and buried the trees. Keywords: Wood growth patterns, Mata sequence, gymnosperms, Triassic climate, petrified forest.
