Influence of external loads to wind turbine tower
Authors: Petrovic Marin , Isic Nejra
Published: July 2021

One of the most important parts of a wind turbine is a tower. There are various designs of the wind turbine towers, and they are most often made of steel pipes, lattice towers or concrete towers. In order to increase energy density to meet the growing electricity needs, larger wind turbine projects have been developed. Larger wind turbine towers can generate more electricity, but such large sizes also create higher costs in terms of development and maintenance. This research sets up a model of a wind turbine tower, where the load to the tower is calculated by its relation to the wind velocity. Analytical approach coupled with a finite element method (FEM) is used to analyse the distribution of tower stresses under these loads. The fatigue analysis of the column is performed using the load from its own weight, the weight of the housing and the distribution of the wind velocity. The effects of different loads are also compared. The results show that the main loads of the tower are the wind force acting on the area of ??rotation of the wind turbine blades and the moment caused by the uneven wind velocity. Construction is modelled using SolidWorks modelling package, where the analysis was performed using FEM in ANSYS software. As a result of the analysis, the stress distribution in the support was determined and compared with analytical calculations.

DIVERSIDADE NA ESCOLA: PROMOVENDO A IGUALDADE E A DEMOCRACIA
Authors: Almeida Flávio Aparecido de
Published: July 2021

A temática diversidade está na ordem do dia, em pauta, sendo debatida no contexto educacional, onde se faz necessário a revisão de valores e atitudes que colaborem para superar as injustiças, preconceitos e estereótipos existentes no contexto escolar e também social. É preciso compreender que a diversidade se constitui um cenário em constante transformação, marcado por lutas e reivindicações, tanto do ponto de vista teórico quanto da prática social, e precisa que o professor esteja preparado para lidar com a diferença, respeitando a pluralidade de ideias, a história e cultura de vida do educando, sua concepção de mundo, criando ações onde a tolerância e o respeito ao outro possa ser construído. O objetivo da pesquisa é refletir sobre a diversidade no contexto da educação atual, assim como a necessidade de o professor estar preparado para trabalhar a diversidade em sala de aula, nas turmas do Ensino Fundamental. Acredita-se que a compreensão da diversidade esteja presente não apenas nos discursos, mais que seja relacionada com o fazer pedagógico em sala de aula, ou seja, é preciso que a diferença represente ponto de partida para conquistas democráticas.
POLÍTICAS PÚBLICAS E DIREITOS DOS USUÁRIOS DO SISTEMA ÚNICO DE SAÚDE (SUS) COM DIABETES MELLITUS (DM)

Published: July 2021

Este trabalho teve como objetivo revisar os conhecimentos sobre os direitos dos usuários diabéticos no âmbito do Sistema Único de Saúde (SUS) no Brasil, trazendo subsídios para conhecimento dos profissionais de saúde e incentivando a divulgação e orientação sobre os direitos destes. Trata-se de estudo narrativo de revisão bibliográfica baseado na legislação e em artigos científicos. Verificaram-se que os direitos dos pacientes com diabetes estão previstos em lei e representados em vários programas do SUS sob diversas frentes, como: acompanhamento multiprofissional, fornecimento de medicamentos e insumos, cirurgia metabólica, assistência domiciliar e escolar. Entretanto, a realidade é muito diferente quando se trata da vida real do cotidiano enfrentado tanto pelos pacientes e pelos profissionais que lidam diretamente com este problema. A irregularidade de acesso aos medicamentos, a indisponibilidade de fármacos modernos, a falta de divulgação de informações sobre os direitos dos pacientes, a demanda por consultas, a falta de recursos humanos e a pouca integração entre os profissionais e gestores são algumas falhas apontadas; muitas vezes graves. Dessa forma, tal situação propicia um contexto em que a prevenção, o controle e a educação, acerca da patologia, são profundamente negligenciadas. Ademais, na perspectiva de gastos públicos, a consequência é um aumento considerável do custo com internações pelas complicações da doença, crônicas e agudas, aposentadorias precoces e faltas ao trabalho e outras intercorrências outras diversas.

Published: July 2021

Este trabalho buscou detectar a ocorrência do efeito índice nas recomposições da carteira teórica do Ibovespa, efeito este que se manifesta pela ocorrência de retornos anormais oferecidos pelas variações nos preços das ações que foram incluídas ou excluídas da carteira. A ocorrência do efeito índice tem implicações sobre a eficiência informacional de mercado e pode representar oportunidades de investimento nos mercados acionários. Os dados utilizados para aplicação da técnica do Estudo de Eventos são referentes ao período que abrange os anos de 2010 a 2016. Os resultados obtidos com a investigação de 33 eventos (11 exclusões de ações e 22 inclusões) revelaram a presença de retornos anormais, principalmente após a divulgação da primeira prévia da recomposição da carteira teórica e após a divulgação da carteira definitiva para o quadrimestre. Neste último caso, foram detectados retornos anormais exclusivamente para as ações excluídas da carteira, o que é um resultado inovador para a investigação em questão, frente ao que consta na literatura, e que se mostraram negativos, conforme se detectou em outros estudos publicados sobre o tema.
LIBERDADE E PANDEMIA
Authors: Silva Jocelino Tramontin da , Pavan Karla Eduarda Modena , Dall Asta Renata
Published: July 2021

Este trabalho, de pesquisa bibliográfica, visa delinear uma ideia de liberdade em tempos de pandemia. Trazer uma ideia do pensar coletivo. Debruçar-se sobre a forma de pensar em democracia, de forma real, onde a minha liberdade não pode ser absoluta, onde a liberdade de um não pode prejudicar a coletividade. Neste momento de coronavírus devemos pensar em saúde coletiva, pois uma ação minha, de forma descuidada pode vir a contaminar aos demais. O que devemos valorar com maior peso neste momento? Pode-se escolher em não ter saúde em prol da liberdade? Estas são questões que vem à tona e que merecem nossa reflexão. O ano de 2020 foi doloroso para todo mundo. A pandemia de covid-19 causou muitos estragos na vida de milhões de pessoas – muitos morreram e muitos foram contaminados e sofreram as graves consequências da doença. Em todos os países, os mais pobres sofreram os maiores impactos, perdendo emprego e renda, enquanto os mais ricos conseguiram se recuperar em tempo recorde. A pandemia de covid-19 expôs, alimentou e aumentou as desigualdades econômicas, de raça e gênero por toda a parte.
Three-Dimensional Radiative Flow of Hybrid Nanofluid Past a Shrinking Plate with Suction

Hybrid nanofluid has been widely used in various heat transfer applications especially as the heat exchanger due to the great thermal conductivity compared to the conventional fluid. However, numerous investigations should still be carried out to properly understand its properties. Hence, in this study, a three-dimensional radiative flow of hybrid Cu-Al2O3/water nanofluid past a permeable shrinking plate is numerically analyzed. The boundary layer including the energy equations are reduced to a system of ordinary differential equations using the similarity transformations and are then solved numerically by using the bvp4c solver in MATLAB. The application of suction through the permeable plate is necessary in aiding the fluid motion past the shrinking surface. Dual solutions are also observable, hence the stability analysis is conducted to mathematically validate the real solution. The enhancement of copper volumetric concentration in the hybrid nanofluid is capable in decelerating the boundary layer separation.

Juan García del Río: El primer canciller del Perú
Authors: Chanamé Orbe Raúl
Published: July 2021

El Perú nació como un referente en el Derecho Internacional Público en los mismos preparativos a la Expedición Libertadora del Sur, con el Tratado que suscribieron el Estado de Chile y las Provincias Unidas de Rio de la Plata (1819). En todos estos actos jurídicos preparatorios a la independencia, participó sobresalientemente Juan García del Rio, amigo y Secretario de Gobierno de José de San Martín. García fue protagonista de la Conferencia de Paz con los delegados del Virrey Pezuela, del Comisionado Regio Abreu y del Virrey La Serna. Cuando se estableció el Protectorado (1821), conformó el primer gabinete, como Secretario de Gobierno y Relaciones Exteriores del flamante gobierno peruano, siendo considerado por esta razón como el primer Canciller del Estado peruano.
participación del Perú en el consejo de seguridad durante el siglo XX
Authors: Morote Canales Ricardo
Published: July 2021

El presente trabajo muestra las tres ocasiones en que el Perú, como miembro fundador de las Naciones Unidas, ha participado en el Consejo de Seguridad (1955-1956), (1973-1974) y (1984-1985) de manera constructiva y guiado siempre por los principios y propósitos de la Carta de las Naciones Unidas para alcanzar la paz y seguridad internacionales. Los ejes temáticos más relevantes en este periodo son los referidos a derechos humanos, derechos civiles y políticos, seguridad internacional, descolonización y libre determinación de los pueblos. Entre los principales asuntos que se desarrollan se encuentran: la Cuestión Palestina y el Oriente Medio, la crisis del Canal de Suez, el Apartheid y descolonización en África Meridional, la Cuestión de Chipre y el asunto de Nicaragua. Estos asuntos llevaron décadas para su solución y algunos persisten hasta la actualidad. Asimismo, se puede apreciar que la interacción entre los Estados y las Naciones Unidas a través de las resoluciones y decisiones de la Asamblea General y del Consejo de Seguridad, así como con las opiniones consultivas y jurisprudencia de la Corte Internacional de Justicia, irán sentando las bases del moderno derecho de los tratados, jurisprudencia y doctrina generando la evolución y mayor desarrollo del Derecho Internacional caracterizado por el establecimiento de importantes instrumentos complementarios a la Carta de las Naciones Unidas.
The First OGLE-discovered Ultracompact X-Ray Binary is an Intermediate Polar

erg s−1, its X-ray emission is also variable and correlated with the optical variability. To determine the nature of this variable source, specifically the masses and types of its binary components, we first consider an attractive possibility that the optical variation is due to the secondary’s ellipsoidal variation and a strong gravitational wave emission drives the orbital decay. However, we cannot find an allowable solution to the secondary that simultaneously satisfies the three constraints: an ultratight orbit, the bright absolute magnitude, and the large-amplitude brightness variation. Moreover, the inferred mass-transfer rate is too high. This scenario is therefore ruled out. We then find the system is fully consistent with an “intermediate polar” model, in which the optical and X-ray emission comes from a magnetized white dwarf (WD) accreting from a low-mass (≲

) main-sequence secondary. The observed period decay is the accretion-driven spin-up of the WD. The WD spin period is 12.8 minutes and the orbital period is shorter than 10 hr. The method presented here can be applied to other UCXB candidates or impostors with only time-domain data available.
Impact of the New Measurement of the 12C + 12C Fusion Cross Section on the Final Compactness of Massive Stars
Authors: Chieffi Alessandro , Roberti Lorenzo , Limongi Marco , La Cognata Marco , Lamia Livio , Palmerini Sara , Pizzone Rosario Gianluca , Spartà Roberta , Tumino Aurora
Published: July 2021

We discuss how the new measurement of the 12C + 12C fusion cross section carried out with the Trojan Horse Method affects the compactness of a star, i.e., basically the binding energy of the inner mantle, at the onset of the core collapse. In particular, we find that this new cross section significantly changes the dependence of the compactness on the initial mass with respect to previous findings obtained in Chieffi & Limongi by adopting the classical cross section provided by Caughlan & Fowler. A non-monotonic but well-defined behavior is also confirmed in this case and no scatter of the compactness around the main trend is found. Such an occurrence could impact the possible explodability of the stars.
Deleuze/Spinoza
Authors: Negri Antonio , Milocco Viola
Published: July 2021

Cet article s’interroge sur le sens du rapprochement entre Spinoza et Masaniello opéré par Gilles Deleuze et Félix Guattari dans L’Anti-Œdipe . L’enjeu est de penser une puissance révolutionnaire irréductible à la manière dont se pensait la révolution dans les partis ou les groupuscules d’extrême gauche au moment de Mai 68. Contre le cloisonnement ascétique du désir, Deleuze et Guattari inventent grâce à Spinoza un mode d’être révolutionnaire absolument nouveau : celui d’une libération désirante des singularités nomades qui, en se rencontrant et en s’organisant, créent des collectifs dans lesquels les rapports de pouvoir et la hiérarchie ne reviennent pas entraver les flux du désir. La déception qui a fait suite aux espoirs portés par Mai 68 s’explique en partie par une insuffisante réflexion sur la question de l’institution et sur la manière d’institutionnaliser ces puissances révolutionnaires. Les écrits de Deleuze et Guattari eux-mêmes révèlent l’impasse de cette génération et nous permettent de mieux comprendre ce que signifie, pour nous, aujourd’hui, la révolution.
Fichte et la tradition mystique
Authors: Radrizzani Ives
Published: July 2021

Cette contribution vise à répertorier les traces d’une influence de la mystique dans le corpus fichtéen et à définir un cadre interprétatif pour expliquer le recours par Fichte à un langage mystique dans L’Initiation à la vie bienheureuse . Un examen attentif des diverses sources laisse apparaître que la tradition mystique et Jacob Böhme en particulier, portés par un puissant souffle poétique, peuvent remplir à l’égard de la philosophie un rôle propédeutique par leur capacité à élever le public au suprasensible, mais doivent également y borner leurs prétentions. Fichte dénonce en effet sur un plan philosophique leur caractère dogmatique et ne leur accorde de valeur qu’éclairés par la critique.
Le logement, ressource du bien-vieillir

Le logement est concerné de nombreuses façons par l’avancée en âge : passage à la retraite, évolutions familiales ou changement des rythmes et activités du quotidien. Aussi, dans sa matérialité, comme à travers les liens sociaux qui s’y jouent, l’habitat peut être un « support » à l’existence 1 . C’est ce sur quoi travaillent Audrey Courbebaisse, chercheuse dans la cellule de recherche Uses and Spaces à l’Université catholique de Louvain, et Damien Vanneste, chercheur au sein de l’unité HADéPaS à l’Université catholique de Lille.

La société civile palestinienne face à la situation coloniale. Diffusion du néolibéralisme et tensions idéologiques en Cisjordanie
Authors: Garrault Antoine
Published: July 2021

À partir d’une enquête de terrain menée en Cisjordanie entre 2011 et 2017, cet article analyse les relations de pouvoir concrètes liées à la diffusion du néolibéralisme au sein de la société civile palestinienne. En nous basant sur une série d’observations participantes et d’entretiens menés avec des militants engagés contre l’occupation israélienne ainsi qu’avec des membres d’ONGs de développement, il vise à comprendre les tensions idéologiques - affectant ces groupes d’acteurs - qui résultent des contradictions entre les incitations néolibérales diffuses et les exigences de la lutte anticoloniale.
The International Criminal Court’s Decision on its Territorial Jurisdiction over Palestine: Between Power Dynamics and Political Legitimacy
Authors: Rémond-Tiedrez Juliette
Published: July 2021

En février 2021, la Chambre préliminaire I de la Cour pénale internationale a estimé que la Cour avait juridiction sur la Palestine. Un mois plus tard, la Procureure a formellement ouvert une enquête. Ces décisions ont marqué un tournant dans l’internationalisation de la question palestinienne tout en permettant à la Cour de contrecarrer les critiques selon lesquelles elle serait néo-colonialiste et ne ciblerait que de faibles États africains. Cependant, les décisions de la CPI ont provoqué de nouvelles critiques d’Israël et de ses alliés affirmant que la Cour serait partiale et aurait excessivement étendu sa juridiction. Du point de vue du leadership palestinien (Cisjordanie), qui voit le recours à la CPI comme une stratégie pour maintenir sa légitimité décroissante, ces décisions sont présentées comme une victoire. Ce papier analyse les dynamiques de pouvoir en jeu dans le processus d’internationalisation de la question palestinienne, avec une attention particulière accordée au rôle de la Cour pénale internationale.
The “Nationalist” Subordination of the Palestinian Left
Authors: Saverio Leopardi Francesco
Published: July 2021

Cet article soutient que la subordination vécue par la gauche palestinienne tout au long de son histoire, est liée à son acceptation du nationalisme palestinien tel que conçu par le Fatah comme paradigme fondateur de l’Organisation pour la Libération de la Palestine (OLP). La gauche utilisa la politique du consensus et la compétition nationaliste pour influencer le Fatah et les orientations générales du mouvement national. Lorsque ces options perdirent leur efficacité, la gauche arrêta d’incarner une opposition crédible et se trouva devant une marginalisation croissante. Des évènements extérieurs compliquèrent davantage la condition de la gauche face au bipolarisme Fatah-Hamas grandissante de la politique palestinienne. Axé sur des sources primaires et l’étude de la vaste historiographie sur le sujet, cet article montre le lien entre le respect de la gauche pour ses paradigmes nationalistes fondateurs et son déclin.
Les « niches » de transition comme espace de renégociation du système énergétique : le cas de l’autoconsommation
Authors: Gigout Élodie , Mayer Julie C. , Dumez Hervé
Published: July 2021

Considérée comme un levier de la transition énergétique, l’autoconsommation (AC) constitue une pratique émergente dont le développement à grande échelle est paradoxalement controversé. Définie comme le fait de consommer sa propre énergie produite localement, l’AC peine encore aujourd’hui à décoller et suscite de nombreux débats de la part de l’ensemble des acteurs de la filière en France. Cet article se propose d’éclairer ce nouvel objet qu’est l’autoconsommation électrique, à partir de la notion de « niche » de transition (Schot et Geels, 2007), c’est-à-dire un espace d’expérimentation capable de contribuer, sous certaines conditions, à transformer en profondeur un système établi. Identifier la niche qui a conduit à la transformation d’un système est aisé a posteriori . Mais on peut supposer qu’une niche, au moment où elle n’est encore qu’une niche, suscite des débats nourris. Dans cet article, nous nous intéressons à l’AC dans cette perspective : comment les acteurs, par leurs discours qui orientent leurs pratiques, s’affrontent-ils, entre ceux qui veulent un développement maîtrisé de la niche et ceux qui veulent la transformation du système ?
Le coaching : exploration d’une pratique
Authors: Ayache Magali , Dumez Hervé
Published: July 2021

Le marché du coaching est en pleine croissance. À partir d’une série d’entretiens avec des coachs, indépendants, liés à un cabinet ou internes à l’entreprise, complétés par une observation non participante à deux séances de mentoring collectif, nous nous interrogeons dans cet article sur le paradoxe d’une pratique sans fondement théorique (ou pouvant faire référence à une multitude d’approches – psychologie, neurosciences, etc.), mais très cadrée (une dizaine de séances, dont deux tripartites – coach, coaché, représentant de l’entreprise). L’hypothèse formulée est que l’explication de ce paradoxe est à chercher dans la nature marchande de la relation de coaching, qui explique son cadrage strict compatible avec des approches multiples laissées au libre choix du coach.
Caractéristiques de l’entrepreneuriat genré dans un pays en développement, le cas du Burkina Faso

Published: July 2021

Cet article tente d’analyser les caractéristiques de l’entrepreneuriat genré au Burkina Faso. Note étude quantitative menée auprès 272 entrepreneurs (hommes et femmes), dévoile que les entrepreneures burkinabè représentent 22% du total des entrepreneurs. Elles sont plus éduquées que leurs homologues masculins. Elles entreprennent majoritairement dans un domaine proche de leur formation. Plutôt jeunes (38 ans) et majoritairement mariées, elles sont en position Pull. Elles souffrent peu du manque d’accompagnement et du manque de financement car elles reçoivent le soutien de leur entourage. Elles dirigent des entreprises de 10 salariés et plus. Enfin, leurs entreprises dégagent une rentabilité quasi identique à celle créées par des hommes, voire légèrement supérieure.
Monde chaotique : au-delà de la résilience, vers l’antifragilité
Authors: Frimousse Soufyane , Gaillard Hugo
Published: July 2021

Ce travail aborde le potentiel des travaux concernant l’antifragilité (Taleb, 2012 ; 2013) pour notamment compléter le concept de résilience à l’échelle individuelle et organisationnelle. Nous proposons une distinction entre le fragile, le résilient et l’antifragile. Ces capacités se distinguent par la nature des décisions prise en contexte de crise, et la finalité de ces décisions sur l’état psychologique et professionnel des individus : l’antifragile se renforce par le chaos. Sont ensuite discutées les conditions individuelles et organisationnelles de l’émergence de ces capacités. Nous considérons finalement l’antifragilité aux niveaux organisationnels, des équipes et individuel. Nous introduisons la notion de sentiment d’antifragilité, et posons l’hypothèse qu’elle contribue à l’antifragilité entendue comme capacité. Le travail abouti sur la proposition d’un programme de recherche qui aborde le positionnement de ce concept (i.e. les niveaux de son analyse), l’exploration et enfin les outils de mesure à développer.
Expérimentation de la négociation interindividuelle entre cadres et ouvriers dans le contexte socio-politique chinois actuel
Authors: Tang Ziyuan , Ruffier Jean
Published: July 2021

Cet article évalue une expérience de négociation interindividuelle dans une usine chinoise. Le contexte politique actuel, ainsi que les traditions locales de management, interdisent pratiquement de donner un pouvoir de négociation aux salariés. La méthode choisie a consisté à prendre l’intervenant comme un médiateur qui remplace la négociation directe par des échanges sur les types de changements à introduire et les sanctions/récompenses afférentes. L’expérience s’est faite sur un groupe expérimental, contrasté par un groupe témoin. L’évaluation positive, tant au plan économique que social, montre la faisabilité et l’acceptabilité de cette démarche en Chine.
Le style d’achat hybride : conceptualisation et proposition d’un instrument de mesure

Published: July 2021

L’article présente une échelle de mesure du style d’achat hybride. Elle semble être plus que nécessaire pour la compréhension d’un nouveau modèle d’achat qui rompt avec tous les modèles classiques. Après une délimitation conceptuelle du style d’achat hybride, un nouvel instrument de mesure tridimensionnel est proposé. La démarche intègre à cette partie théorique une série d’études qualitatives et quantitatives. Ces dernières permettent la vérification de la fiabilité et des validités convergente et discriminante. Les résultats indiquent également que le style d’achat hybride mesuré par le nouvel instrument, prédit bien les différents éléments de la prise de décision d’achat.
Dynamical behavior of a stochastic predator-prey model with general functional response and nonlinear jump-diffusion
Authors: Zhang Xinhong , Yang Qing
Published: July 2021

In this paper, we consider a stochastic predator-prey model with general functional response, which is perturbed by nonlinear Lévy jumps. Firstly, We show that this model has a unique global positive solution with uniform boundedness of \begin{document}$ \theta\in(0,1] $\end{document}-th moment. Secondly, we obtain the threshold for extinction and exponential ergodicity of the one-dimensional Logistic system with nonlinear perturbations. Then based on the results of Logistic system, we introduce a new technique to study the ergodic stationary distribution for the stochastic predator-prey model with general functional response and nonlinear jump-diffusion, and derive the sufficient and almost necessary condition for extinction and ergodicity.
Population dynamics and economic development
Authors: Caravaggio Andrea , Gori Luca , Sodini Mauro
Published: July 2021

This research develops a continuous-time optimal growth model that accounts for population dynamics resembling the historical pattern of the demographic transition. The Ramsey model then becomes able to generate multiple determinate or indeterminate stationary equilibria and explain the process of the transition from a state with high fertility and low income per capita to a state with low fertility and high income per capita. The article also investigates the emergence of damped or persistent cyclical dynamics.
Firms, technology, training and government fiscal policies: An evolutionary approach
Authors: Accinelli Elvio , Martins Filipe , Muñiz Humberto , Oliveira Bruno M. P. M. , Pinto Alberto A.
Published: July 2021

In this paper we propose and analyze a game theoretical model regarding the dynamical interaction between government fiscal policy choices toward innovation and training (I&T), firm's innovation, and worker's levels of training and education. We discuss four economic scenarios corresponding to strict pure Nash equilibria: the government and I&T poverty trap, the I&T poverty trap, the I&T high premium niche, and the I&T ideal growth. The main novelty of this model is to consider the government as one of the three interacting players in the game that also allow us to analyse the I&T mixed economic scenarios with a unique strictly mixed Nash equilibrium and with I&T evolutionary dynamical cycles.
Homotopy continuation for the spectra of persistent Laplacians
Authors: Wei Xiaoqi , Wei Guo-Wei
Published: July 2021

The \begin{document}$ p $\end{document}-persistent \begin{document}$ q $\end{document}-combinatorial Laplacian defined for a pair of simplicial complexes is a generalization of the \begin{document}$ q $\end{document}-combinatorial Laplacian. Given a filtration, the spectra of persistent combinatorial Laplacians not only recover the persistent Betti numbers of persistent homology but also provide extra multiscale geometrical information of the data. Paired with machine learning algorithms, the persistent Laplacian has many potential applications in data science. Seeking different ways to find the spectrum of an operator is an active research topic, becoming interesting when ideas are originated from multiple fields. In this work, we explore an alternative approach for the spectrum of persistent Laplacians. As the eigenvalues of a persistent Laplacian matrix are the roots of its characteristic polynomial, one may attempt to find the roots of the characteristic polynomial by homotopy continuation, and thus resolving the spectrum of the corresponding persistent Laplacian. We consider a set of simple polytopes and small molecules to prove the principle that algebraic topology, combinatorial graph, and algebraic geometry can be integrated to understand the shape of data.
La fortificación de campaña en Cuba durante la guerra del Asiento: la definición de un modelo defensivo en el Caribe hispano
Authors: López Hernández Ignacio J.
Published: July 2021

La guerra del Asiento ha sido identificada como el primer gran conflicto armado entre potencias europeas que tuvo al continente americano como su origen y escenario. La escala del enfrentamiento obligó a la Corona española a definir un nuevo plan defensivo en el Caribe, cuyos detalles aún están pendientes de precisar. Este trabajo busca documentar, analizar y probar a partir de noticias, en su mayoría inéditas, el papel fundamental jugado por la fortificación de campaña en la exitosa defensa de Cuba frente a las amenazas y ataques británicos que tuvieron lugar entre 1739 y 1748. Con ello será posible redefinir varios rasgos identitarios de la fortificación del Caribe hispano de esta época.

Published: July 2021

Estudos sobre resiliência tem aumentado partir dos avanços da psicologia positiva, bem como sobre enfrentamento e autoeficácia no contexto de doenças crônicas. O objetivo do estudo foi avaliar os efeitos de uma intervenção em grupo para o desenvolvimento de resiliência, stratégias de enfrentamento e autoeficácia em pessoas adultas com diagnóstico de diabetes mellitus tipo 2, divididas em grupos experimental (GE) e controle (GC). Participaram quatro pessoas adultas no GE e quatro no GC. A intervenção consistiu de oito encontros, com duas horas de duração. Os resultados indicaram que a intervenção propiciou resultados positivos no enfrentamento no problema e na autoeficácia, fatores importantes no gerenciamento de condições adversas. Apesar da diferença entre as médias das variáveis enfrentamento focalizado no problema, busca de suporte social e autoeficácia, a comparação dos momentos pré e pós intervenção do GE não revelou significância estatística. Não se observou diferença estatística nas análises dos momentos 1 e 2 do GC, bem como nas comparações intergrupos. O número pequeno de participantes foi uma limitação da pesquisa. O estudo da resiliência, do enfrentamento e da autoeficácia visaram contribuir com pesquisas acerca de aspectos humanos positivos e sua utilização no contexto da diabetes mellitus.

Published: July 2021

O traço de personalidade perfeccionista é caracterizado como um conjunto de pensamentos que buscam a perfeição e estabelecem padrões excessivamente altos de desempenho e está altamente relacionado a impactos nas relações pessoais. Considerando os possíveis impactos que essas características possam ter em relação à conjugalidade, investiga-se a possibilidade de que os traços de personalidade se associem à qualidade conjugal. Portanto, realizou-se uma revisão sistemática da literatura com objetivo de verificar as relações entre as dimensões do traço de personalidade perfeccionista e o relacionamento conjugal em estudos empíricos. A revisão foi realizada seguindo as diretrizes do PRISMA. Foram consultadas as bases de dados com os descritores: “perfeccionismo”, "personalidade'' e “conjugalidade” e seus equivalentes em inglês, foram selecionados estudos completos publicados entre os anos de 2015 e 2020. Três artigos compuseram esta pesquisa. Os resultados encontrados demonstraram que o perfeccionismo pode ter caráter adaptativo e/ou desadaptativo e que as dimensões do traço de personalidade perfeccionista, assim como outras variáveis pessoais, impactam nos níveis de satisfação de relacionamentos conjugais. Esses achados sustentam a relevância de se incluir o estudo do perfeccionismo no contexto das relações conjugais, assim como em intervenções em nível de prevenção e tratamento para qualidade conjugal.

Published: July 2021

O presente artigo objetivou realizar uma revisão sistemática das pesquisas empíricas sobre educadores sociais em abrigos destinados a crianças e adolescentes. Foram consultados os artigos disponíveis nas plataformas (Google Acadêmico, SciELO, Redalyc, Periódicos CAPES/MEC, Pepsic e BVS Psicologia Brasil) para identificar as pesquisas publicadas no período de 2015 a 2020.  Dez artigos incluídos foram categorizados em cinco categorias: Vivência, Vínculo, Prática, Transtornos Mentais, e Formação. Destacou-se a importância dos educadores enquanto atores sociais e aspectos das necessidades deles: reconhecer os afetos, pois o cuidado se apresentou como uma tarefa, e assim, revelou risco de adquirir um caráter operacional e assistencialista; capacitação inicial baseada em critérios de qualidade; formação continuada com o apoio e parceria de profissionais que possuam conhecimento reconhecido no assunto e oferta de serviços de assistência psicológica e psiquiátrica. Trata-se de uma temática de estudo que possibilita a análise de aspectos psicossociais para o desenvolvimento de intervenções com o foco nas necessidades dos educadores sociais.

Published: July 2021

The present study sought to synthesize available evidence on the role of self-compassion in elders aged 60 or above and its potential implications during the process of aging. A systematic review was conducted in order to search for empirical scientific articles with quantitative, qualitative, or mixed methods with a focus on self-compassion in samples with elders aged 60 years or more. Searches were carried out in the Psycinfo, Scopus, Pubmed, Embase and Cochrane databases, without limit of time. After the application of including and excluding criteria, 11 articles were considered eligible for this review, with all presenting good methodological quality. Self-compassion was found to be a promising skill that can promote healthy psychosocial aging, enabling a better adjustment to changes associated with aging. Such results contribute to the development of new mental health intervention protocols, especially in the field of psychogerontology. There is a need for more longitudinal research and investment in the development of specific interventions for this age group.
Severe retinal pigment epitheliopathy following brilliant blue G-assisted epiretinal membrane peeling
Authors: Bindra Chahveer , Bindra Parminder , Bindra Preeti
Published: July 2021

To report a case of severe retinal pigment epitheliopathy following 23G pars plana vitrectomy and brilliant blue G (BBG) assisted epiretinal membrane (ERM) peeling in Stage IV primary ERM. Multimodal imaging analyses, including fundus photography, optical coherence tomography, and fundus autofluorescence, were performed to evaluate preoperative and postoperative findings. The patient underwent uneventful pars plana vitrectomy with BBG-assisted ERM peeling with the help of xenon endoilluminator and fine tipped forceps. Six weeks after surgery, the patient complained of paracentral scotomas. On evaluation with retinal imaging, pigmentary alteration was seen over the posterior pole corresponding to the peeled area. A risk of retinal pigment epitheliopathy after uneventful vitrectomy with BBG-assisted ERM peeling is present even with modern endoilluminators. The retinal phototoxicity, use of vital dyes, duration of surgery, stage of ERM preoperatively, and mechanical trauma during peeling may be associated risk factors.
Comparing the efficacy of 2% topical rebamipide and 0.1% topical sodium hyaluronate with or without 0.05% topical cyclosporine in patients with dry eye disease
Authors: Gandhi Priyanka V. , Telang Omkar , Morepatil Vrunda
Published: July 2021

Background:

Dry Eye Disease (DED) is a multifactorial and complex disease of the ocular surface, with a high prevalence in adults.

Aims and Objectives:

To compare the efficacy of 2% topical Rebamipide and 0.1% topical Sodium hyaluronate with or without 0.05% topical cyclosporine in patients with dry eye disease (DED).

Materials and Methods:

This prospective, randomised, comparative, interventional study was conducted at a tertiary level academic centre on 240 eyes of 120 patients having DED, with Schirmer's test (without anesthesia) value less than or equal to 10mm and tear film breakup time (TBUT) less than or equal to 10 secs. After detailed ophthalmic examination, patients were randomly allocated in 4 different groups (A B C D). Group A were given 2% topical Rebamipide, group B received 2% topical Rebamipide with 0.05% topical Cyclosporine, group C were started on 0.1% topical Sodium Hyaluronate and group D were given 0.1% topical Sodium Hyaluronate with 0.05% cyclosporine. Each of these drops was given for 4 times a day for a period of 12 weeks. All patients were followed up after 2 weeks, 4 weeks and 12 weeks.

Results:

Out of 120 patients, 79 (65.83%) were female and 41 (34.16%) were male. The change in the mean schirmer's score and mean TBUT score was statistically significant in all four groups from baseline to 12 weeks (p<0.05). On comparing with each other, no significance difference was noted in any group.

Conclusion:

According to our study, 3 months of treatment with either 2% topical Rebamipide or 0.1% sodium hyaluronate is equally effective for DED and addition of 0.05% cyclosporine have no adjunctive role.

Published: July 2021

Purpose:

The purpose of this study is to determine the corneal biomechanical properties in patients with connective tissue disorders (CTDs) and compare them with age-matched healthy control.

Materials and Methods:

In this cross-sectional study, 62 patients (study group) with CTDs and 44 healthy patients (control) were analyzed by Ocular Response Analyzer (Reichert Inc., Depew, N. Y., USA) and Corneal Pachymetry (SP-2000, Tomey, Nagoya, Japan). The right eye of all patients was assessed for corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPc), and Goldmann-correlated intraocular pressure (IOPg), and central corneal thickness (CCT).

Results:

Mean CH (9.54 ± 1.66 mm Hg [study group] and 10.62 ± 1.21 mm Hg [control]; P = 0.013) and mean CRF (9.95 ± 1.47 mm Hg [study group] and 10.76 ± 1.25 mm Hg [control]; P = 0.040) were significantly different between groups. Mean IOPc, IOPg, and CCT were not significantly different between groups. In the subgroup analysis of study cases (oral steroid versus nonsteroid therapy) of CTDs, CRF which was significantly lower in steroid (9.25 mm Hg) compared nonsteroid therapy (10.20 mm Hg) (P = 0.045), whereas, other parameters such as CCT, CH, IOPc, and IOPg were comparable between the two groups (P ≥ 0.05).

Conclusion:

CH is altered in CTDs which may be an independent risk factor for glaucoma and might underestimate intraocular pressure so CH is an important consideration in patients with CTDs.s

Published: July 2021

Cervical cancer ranks as the four leading cause of cancer death in women worldwide. It is the third most common cancer in India. Most patients present in advanced stages. Concurrent chemoradiation is the standard of treatment for locally advanced cervical cancer.

Aims:

The aim of the study was to compare the treatment response and hematological, gastrointestinal, and skin toxicity of cisplatin versus gemcitabine as concurrent chemoradiotherapy.

Materials and Methods:

This study was conducted from February 2017 to August 2018. Sixty patients of squamous cell carcinoma cervix with Stage IIB to IIIB were randomly allocated to either weekly gemcitabine (observation arm) 150 mg/m2 or cisplatin (control arm) in the dose of 35 mg/m2 along with concurrent radiotherapy. Treatment response and toxicities of both drugs were evaluated.

Statistical Method:

Statistical analysis was conducted using the Statistical Package for the Social Sciences version 20. Descriptive statistics such as frequency, percentages, mean, standard deviation, and range were used to describe the treatment characteristics.

Results:

Gemcitabine arm has more Grade 2 (23.3% vs. 10%) and Grade 3 (3.3% vs. none) hematological toxicity as compared to cisplatin arm. For gastrointestinal toxicity, Grade 2 toxicity was observed more in cisplatin arm (23.3%) as compared to 13.3% in gemcitabine arm. Skin toxicity was found to be insignificant. There was complete response of 86.7% in cisplatin arm, while 73.3% in gemcitabine arm.

Conclusion:

Cisplatin has a better treatment response as compared to gemcitabine as concomitant chemotherapy agent with external beam radiation therapy. Hematological toxicity was more in gemcitabine arm and gastrointestinal toxicity was more in cisplatin arm. The skin toxicities were comparable in both the arms.
