description: O presente artigo visa elucidar questões que envolvem a Licenciatura em Educação do Campo, os movimentos sociais, seu envolvimento na luta pela adequação da educação em moldes que atendam a diversidade cultural do sujeito do campo, o avanço relacionado ao reconhecimento da cultura e da diversidade do homem do campo, e a importância da preservação de seus costumes dentro das escolas. A valorização do universo rural brasileiro com a criação de uma política de Educação do Campo, suas diretrizes operacionais e os documentos que contornam essa política são objetos de estudo dessa pesquisa, cujo objetivo é assegurar a preservação da identidade e da memória do povo brasileiro em sua essência interiorana, sua oralidade, alfabetização e letramento. Para tanto, queremos responder a algumas questões: o que são Políticas de educação do Campo? Quais movimentos sociais se envolveram nessa demanda? Quais as instituições se envolveram para a criação e regulamentação das políticas de educação do campo? Onde e quando foram criados os primeiros cursos voltados para a formação de educadores do campo? Sobre o que tratam os marcos normativos da Educação do campo? Para tanto, vamos nos servir do seguinte corpus: ementa do curso de Licenciatura em educação do campo da UFMG, bem como as publicações das resoluções, pareceres, decretos e leis que envolvem a educação do campo e seus marcos normativos.

description: Automatic detection of font size finds many applications in the area of intelligent OCRing and document image analysis, which has been traditionally practiced over uncompressed documents, although in real life the documents exist in compressed form for efficient storage and transmission. It would be novel and intelligent if the task of font size detection could be carried out directly from the compressed data of these documents without decompressing, which would result in saving of considerable amount of processing time and space. Therefore, in this paper we present a novel idea of learning and detecting font size directly from run-length compressed text documents at line level using simple line height features, which paves the way for intelligent OCRing and document analysis directly from compressed documents. In the proposed model, the given mixed-case text documents of different font size are segmented into compressed text lines and the features extracted such as line height and ascender height are used to capture the pattern of font size in the form of a regression line, using which the automatic detection of font size is done during the recognition stage. The method is experimented with a dataset of 50 compressed documents consisting of 780 text lines of single font size and 375 text lines of mixed font size resulting in an overall accuracy of 99.67%.

description: O interesse em desenvolver uma investigação envolvendo o humano e o social advém dos meus estudos acerca da imagem docente, em um momento no qual o ensino e a educação fazem parte da pauta dos debates que refletem a ação do professor. Ao longo dos tempos, observo que a temática da profissão docente se intensificou, principalmente, pelo que nos é apresentado nas diferentes esferas de circulação social – mídia, escola, família –, ou seja, um conjunto de discursos que fazem parte da nossa atualidade, mas, também, da nossa memória, uma vez que resgatam imagens e ações de um professor de séculos passados. A partir dessas reflexões, o objetivo deste estudo é analisar o movimento das representações de professores sobre o ser docente. Diante disso, propõe-se um percurso metodológico, pautado numa abordagem linguístico-textual-discursiva, à luz de princípios sociointeracionistas, com vistas a flagrar nos modos de enunciar de professores de língua portuguesa, regularidades que possam revelar os modos de fazer próprios da profissão e também as imagens que dela se faz.

description: We describe the arrival time measurements and timing modeling of the periodic radio flares and optical brightness variations of the M9 ultracool dwarf, TVLM 513-46546. We confirm the stability of the observed period and determine its best-fit value to be 7054.468(+/-)0.007 s over the last 7 years, based on both the new and archival radio observations and the archival optical data. The period, when measured separately for the radio flare and the optical periodicities, is the same to within (+/-)0.02 s. We show that the radio flares are out of phase with respect to the optical brightness maxima by 0.41(+/-)0.02 of the period. Our analysis also reveals that, on shorter timescales, the period varies with the amplitude of (+/-)1-2 s about its long-term average and that these variations are correlated between the radio and the optical wavelengths. These results provide further evidence that TVLM 513-46546 is equipped with a stable, approximately dipolar magnetic field which powers the activity of the star observed over a wide wavelength range, and that the active area has been maintaining its identity and positional stability over no less than 7 years. A stepwise decline of the apparent radio flaring period of TVLM 513-46546 deduced from timing observations with the Arecibo radio telescope in late 2012 and early 2013 suggests that this effect may be the manifestation of differential rotation of the star.

description: As a stable biometric system, iris has recently attracted great attention among the researchers. However, research is still needed to provide appropriate solutions to ensure the resistance of the system against error factors. The present study has tried to apply a mask to the image so that the unexpected factors affecting the location of the iris can be removed. So, pupil localization will be faster and robust. Then to locate the exact location of the iris, a simple stage of boundary displacement due to the Canny edge detector has been applied. Then, with searching left and right IRIS edge point, outer radios of IRIS will be detect. Through the process of extracting the iris features, it has been sought to obtain the distinctive iris texture features by using a discrete stationary wavelets transform 2-D (DSWT2). Using DSWT2 tool and symlet 4 wavelet, distinctive features are extracted. To reduce the computational cost, the features obtained from the application of the wavelet have been investigated and a feature selection procedure, using similarity criteria, has been implemented. Finally, the iris matching has been performed using a semi-correlation criterion. The accuracy of the proposed method for localization on CASIA-v1, CASIA-v3 is 99.73%, 98.24% and 97.04%, respectively. The accuracy of the feature extraction proposed method for CASIA3 iris images database is 97.82%, which confirms the efficiency of the proposed method.

description: A statistical relationship between magnetic reconnection, current sheets and intermittent turbulence in the solar wind is reported for the first time using in-situ measurements from the Wind spacecraft at 1 AU. We identify intermittency as non-Gaussian fluctuations in increments of the magnetic field vector, $\mathbf{B}$, that are spatially and temporally non-uniform. The reconnection events and current sheets are found to be concentrated in intervals of intermittent turbulence, identified using the partial variance of increments method: within the most non-Gaussian 1% of fluctuations in $\mathbf{B}$, we find 87%-92% of reconnection exhausts and $\sim$9% of current sheets. Also, the likelihood that an identified current sheet will also correspond to a reconnection exhaust increases dramatically as the least intermittent fluctuations are removed from the dataset. Hence, the turbulent solar wind contains a hierarchy of intermittent magnetic field structures that are increasingly linked to current sheets, which in turn are progressively more likely to correspond to sites of magnetic reconnection. These results could have far reaching implications for laboratory and astrophysical plasmas where turbulence and magnetic reconnection are ubiquitous.

Na sequência, discutiu-se sobre a estrutura e o funcionamento deste nível de ensino, bem como as competências pedagógicas do professor universitário para posteriormente refletir sobre as implicações de tais questões na relação transferencial estabelecida entre professor e aluno no Ensino Superior. Conclui-se a partir deste estudo bibliográfico que ao conhecer a estrutura e funcionamento do Ensino Superior, bem como as competências do professor universitário torna-se possível refletir sobre os diversos elementos que fazem parte do conjunto de inscrições postas ao professor que antecedem sua entrada na sala de aula e influência direta na relação transferencial que irá estabelecer com seu aluno/acadêmico. Entendeu-se que o professor não está neutro nesta relação, mas sim investido do discurso institucional vigente, o que o coloca mais implicado com o que surge dessa relação.

title: Populism, the Pandemic & Prospects for International Law
Creators: name: McLachlan, Campbell A
Publisher: name: Universität Potsdam
Year: 2020

description: Populism has fatally weakened the world’s ability to respond to COVID-19, by undermining the capacity of the structures and mechanisms of international law to address the pandemic. The pandemic has exposed as a fallacy a key tenet of populism – to protect the ‘people’ of a nation from external forces, including international law. In fact international law, through the principle of self-determination, enshrines the ability of peoples to determine their own political organization. But this does not preclude agreement at the international level on matters of common interest to humanity as a whole that require community action. The prevention of infectious disease is just such a case, which states have long agreed could not remain solely the preserve of national polities, but requires a common international response. This paper, placing the current crisis in light of the development of international health law, critically examines the response of key populist governments to COVID-19 in order to address the larger issue of the implications of populism for the fate of international law.

description: Threshold and ambiguity phenomena are studied in Part 1 of this work where approximations for the mean-squared-error (MSE) of the maximum likelihood estimator are proposed using the method of interval estimation (MIE), and where approximate upper and lower bounds are derived. In this part we consider time-of-arrival estimation and we employ the MIE to derive closed-form expressions of the begin-ambiguity, end-ambiguity and asymptotic signal-to-noise ratio (SNR) thresholds with respect to some features of the transmitted signal. Both baseband and passband pulses are considered. We prove that the begin-ambiguity threshold depends only on the shape of the envelope of the ACR, whereas the end-ambiguity and asymptotic thresholds only on the shape of the ACR. We exploit the results on the begin-ambiguity and asymptotic thresholds to optimize, with respect to the available SNR, the pulse that achieves the minimum attainable MSE. The results of this paper are valid for various estimation problems.

description: Este artigo propõe uma construção alternativa para o conceito de derivada de uma função, um dos conceitos fundamentais do Cálculo Diferencial, aproximando-se do Método das Fluxões de Newton, apresentado no século XVIII através de forte apelo intuitivo. Evitar a construção demasiadamente técnica do conceito de derivada através de um limite indeterminado cuja abstração e formalismo constituem dificuldades adicionais para os alunos foi a principal motivação para este trabalho. Amparados ainda pelo desenvolvimento histórico, acreditamos que a abordagem ora proposta constitua uma alternativa bastante natural tanto para a significação do conceito de derivada, quanto para o desenvolvimento de alguns aspectos técnicos do conteúdo programático de Cálculo, como calcular derivadas e obter as regras de derivação, por exemplo. O principal objetivo deste trabalho é, portanto, fornecer fundamentos que corroborem com esta afirmação.

description: We report measurements of parallaxes and proper motions of ten high-mass star-forming regions in the Sagittarius spiral arm of the Milky Way as part of the BeSSeL Survey with the VLBA. Combining these results with eight others from the literature, we investigated the structure and kinematics of the arm between Galactocentric azimuth around -2 and 65 deg. We found that the spiral pitch angle is 7.3 +- 1.5 deg; the arm's half-width, defined as the rms deviation from the fitted spiral, is around 0.2 kpc; and the nearest portion of the Sagittarius arm is 1.4 +- 0.2 kpc from the Sun. Unlike for adjacent spiral arms, we found no evidence for significant peculiar motions of sources in the Sagittarius arm opposite to Galactic rotation.

description: Extracting a block of interest referred to as segmenting a specified block in an image and studying its characteristics is of general research interest, and could be a challenging if such a segmentation task has to be carried out directly in a compressed image. This is the objective of the present research work. The proposal is to evolve a method which would segment and extract a specified block, and carry out its characterization without decompressing a compressed image, for two major reasons that most of the image archives contain images in compressed format and decompressing an image indents additional computing time and space. Specifically in this research work, the proposal is to work on run-length compressed document images.

description: Le premier objectif de mon mémoire est d’analyser la didactique actuelle de l’histoire au secondaire 1 et la fameuse méthode de Pestalozzi utilisée à l’Institut d’Yverdon pour voir si nous pouvons retrouver entre ces deux manières d’enseigner des leviers motivationnels semblables. Dans ce travail, j’aborde l’importance de la motivation dans l’enseignement d’une discipline telle que l’histoire qui présente pour la plupart des élèves un manque d’intérêt et de sens. Or cette branche les accompagne tout au long de leur scolarité. Une difficulté supplémentaire dans l’enseignement de l’histoire vient également du fait que les classes, auxquelles nous avons à faire, sont souvent composées de « bons » élèves et d’enfants rencontrant de nombreuses difficultés lors de l’analyse de sources et la rédaction de textes synthétiques ou argumentatifs. Nous présentons la méthode de Pestalozzi ainsi que la manière dont l’histoire était enseignée dans son Institut d’Yverdon. Nous introduisons de même le concept de motivation et le développement de la discipline historique qui, depuis la fin du 19ème siècle, mena à notre didactique actuelle de l’histoire. Il est intéressant d’étudier ces deux méthodes censées fonctionner avec tous les élèves dans une époque où ces derniers, nonobstant leurs difficultés ou facilités personnelles, doivent atteindre un socle commun de connaissances assez élevé. Nous développons et comparons enfin deux leçons d’histoire portant sur le même thème, Guillaume Tell, en tenant compte des informations que nous possédons sur l’enseignement de l’histoire à Yverdon et de celles sur la didactique actuelle. Le but de se travail est de mettre en évidence ces leviers, qui s’ils sont les mêmes sont vantés depuis des siècles, afin de pouvoir les mettre en pratique dans notre enseignement actuel.

description: Este artigo teve por objetivo analisar práticas do contexto da escola que contribuem para criar desvios, gerar violências e suas consequências na trajetória escolar dos alunos. Para tanto, utilizou-se de pesquisa qualitativa, tendo como instrumentos para geração de dados: a entrevista de grupo focal e individual, observação e análise documental. Os resultados sugerem que a escola a partir de sua organização pedagógica ajuda a criar o desvio e as formas de controle; os gestores têm dificuldades na medidação dos conflitos; os alunos considerados indisciplinados e/ou violentos ficam enclausurados no ensino fundamental. Eles possuem um perfil comum: são homens, negros, pobres e seus pais possuem baixa escolaridade. Esse grupo é o mais atingido, muitos abandonam a escola. Os que persistem vêm acumulando sucessivas reprovações.

description: We examine the role of spin-orbit coupling in the electronic structure of $α$-RuCl3, in which Ru ions in 4d5 configuration form a honeycomb lattice. The measured optical spectra exhibit a clear optical gap and excitations within the t2g orbitals. The spectra can be described very well with first-principles electronic structure calculations obtained by taking into account both spin orbit coupling and electron correlations. Furthermore, our X-ray absorption spectroscopy measurements at the Ru L-edges exhibit distinct spectral features associated with the presence of substantial spin- orbit coupling, as well as an anomalously large branching ratio. We propose that $α$-RuCl3 is a spin-orbit assisted Mott insulator, and the bond-dependent Kitaev interaction may be relevant for this compound.

Para tanto sua organização consiste em duas partes: a primeira refere-se aos estudos do NEGRI no contexto sócio histórico buscando compreender os eixos de desigualdades de “raça” no contexto da educação brasileira; já a segunda sessão dedica-se à teoria sobre relações raciais no Brasil de autores contemporâneos que são utilizadas como aportes teóricos junto ao NEGRI, bem como um breve relato sobre o campo metodológico, a hermenêutica de profundidade (HP), definida por John B. Thompson (2011). Nossas considerações frente aos estudos apresentados do NEGRI buscaram compreender os eixos de desigualdades de “raça” no contexto da educação, os quais permitiram sustentar uma perspectiva de análise crítica e política para o campo de estudos das relações raciais, com o propósito de descrever e interpretar a operação do racismo estrutural e simbólico na produção e sustentação de desigualdades sociais brasileiras.

Este artigo de revisão da literatura apresenta uma sistematização de alguns resultados da investigação, nacional e internacional, sobre o cyberbullying e o autocyberbullying. As características destes fenómenos e o seu impacto nas vítimas são alvo de reflexão, bem como os fatores que têm vindo a ser identificados como facilitadores ou protetores. A problemática do autocyberbullying merece, neste trabalho, especial atenção, dado que a investigação internacional sobre autocyberbullying alerta para a existência e gravidade deste fenómeno e deixa antever um cenário que pode tornar-se preocupante na adolescência. O artigo termina com uma reflexão sobre a importância de se conhecer a prevalência, as motivações e o impacto do autocyberbullying entre os adolescentes portugueses. Uma melhor compreensão da situação em Portugal possibilitará o desenvolvimento de estratégias eficazes de prevenção e de intervenção.

Neste artigo objetiva-se apresentar resultados de uma atividade desenvolvida com o auxílio das tecnologias na disciplina de Seminário Integrado, a qual visou entender como a inserção das tecnologias favorece os processos de ensino e aprendizagem de forma colaborativa, além de uma avaliação realizada pelos sujeitos sobre determinada atividade. Assim, com o auxílio de oito professores e quarenta alunos, utilizaram-se as redes sociais para a coleta de dados e questionários impressos para avaliar o trabalho desenvolvido na rede; os dados foram analisados de forma quali-quantitativa via uso de gráficos e grafos. Como conclusão, se destaca que as tecnologias proporcionam a qualificação dos processos de ensino e de aprendizagem de forma colaborativa, já que rede tornou-se, de forma crítica e colaborativa, um lugar de produção de conhecimento escolar, exigindo a reestruturação didática e a formação continuada dos professores. Portanto, a inserção das tecnologias deve desenhar, tecer e alinhavar a verticalidade e a horizontalidade da aprendizagem colaborativa, para que os professores e alunos percebam as interfaces dos conteúdos e as possíveis inter-relações de forma relacional e contextual.

description: À l’heure actuelle, nous observons une expansion conséquente du marché des jeux vidéo et de leur présence dans le quotidien des élèves. En conséquence, apparaît aussi un regain d’intérêt pour les serious games – ces jeux vidéo à visée pédagogique notamment sous l’égide de grands éditeurs comme Ubisoft, qui propose un mode éducatif, nommé le « discovery tour », dans son dernier opus d’Assassin’s Creed. En parallèle, d’autres recherches basées sur la ludification apparaissent. Elle consiste à utiliser les mécanismes des jeux hors de leur contexte. Citons par exemple Classcraft, qui utilise ces mécanismes dans un cadre scolaire, plus précisément pour la gestion de classe. Ce mémoire s’intéresse ainsi à la ludification au service de l’enseignement de l’histoire au Secondaire I. Notre recherche vise à exploiter le gameplay des jeux vidéo pour créer des dispositifs didactiques à mettre en place dans nos classes d’histoire. Ces dispositifs se basent sur deux types de jeux vidéo différents : le « point-and-click » et le jeu de gestion et permettent d’identifier les impacts effectifs sur l’apprentissage. Dans ce cadre, nous nous intéressons particulièrement à leur utilité quant à la motivation, à l’autonomie et aux apprentissages réalisés. Ils sont expérimentés dans des classes de 10ème VG et 11ème VP, respectivement sur les thèmes de la révolution industrielle et du nazisme. Notre recherche se déroule en trois temps. La première consiste en la création des dispositifs. Ensuite, leur application en classe. Finalement, intervient la récolte des données sous forme de questionnaire et d’observations. Ces dernières nous permettent de répondre à la problématique initiale. Au terme de ce projet, il apparaît que la ludification a des effets positifs sur la motivation, l’autonomie et l’apprentissage (acquisition de connaissances factuelles et de savoir-faire). Cependant, nos résultats ne permettent pas de définir si nos dispositifs sont plus efficaces que l’enseignement traditionnel de l’histoire, mais leurs effets positifs nous incitent à les recommander comme outils pour varier les approches de l’enseignement. À cet effet, quelques pistes d’évolution de ces dispositifs sont suggérées.

description: We investigate the influence of thermally activated internal molecular dynamics on the phase shifts of matter waves inside a molecule interferometer. While de Broglie physics generally describes only the center-of-mass motion of a quantum object, our experiment demonstrates that the translational quantum phase is sensitive to dynamic conformational state changes inside the diffracted molecules. The structural flexibility of tailor-made hot organic particles is sufficient to admit a mixture of strongly fluctuating dipole moments. These modify the electric susceptibility and through this the quantum interference pattern in the presence of an external electric field. Detailed molecular dynamics simulations combined with density functional theory allow us to quantify the time-dependent structural reconfigurations and to predict the ensemble-averaged square of the dipole moment which is found to be in good agreement with the interferometric result. The experiment thus opens a new perspective on matter wave interferometry as it demonstrates for the first time that it is possible to collect structural information about molecules even if they are delocalized over more than hundred times their own diameter.

description: Este artigo apresenta uma reflexão sobre os fatores que contribuem tanto para o sucesso, quanto para o fracasso, no processo de ensino-aprendizagem da disciplina de matemática, baseada nos dados obtidos por meio da aplicação de dois questionários, um para alunos e outro para os professores de matemática. A pesquisa foi realizada em duas instituições estaduais de ensino fundamental e médio de uma cidade do interior do Paraná. Como resultado deste trabalho, podemos apontar um levantamento de opiniões, tanto positivas quanto negativas, acerca das metodologias adotadas pelos professores de matemática, fato que oportunizou, aos docentes da disciplina, uma reflexão da sua prática pedagógica com o intuito de repensá-la, buscando assim promover um processo de ensino-aprendizagem com mais qualidade. Por último, cabe registrar que tal trabalho também foi útil para que os alunos se sentissem como participantes ativos do processo de ensino-aprendizagem e não apenas espectadores de aulas reprodutivas, pois, ao responderem os questionários puderam externar seus pontos de vista em relação ao assunto abordado

A Hybrid Approach for Co-Channel Speech Segregation based on CASA, HMM Multipitch Tracking, and Medium Frame Harmonic Model

description: This paper proposes a hybrid approach for co-channel speech segregation. HMM (hidden Markov model) is used to track the pitches of 2 talkers. The resulting pitch tracks are then enriched with the prominent pitch. The enriched tracks are correctly grouped using pitch continuity. Medium frame harmonics are used to extract the second pitch for frames with only one pitch deduced using the previous steps. Finally, the pitch tracks are input to CASA (computational auditory scene analysis) to segregate the mixed speech. The center frequency range of the gamma tone filter banks is maximized to reduce the overlap between the channels filtered for better segregation. Experiments were conducted using this hybrid approach on the speech separation challenge database and compared to the single (non-hybrid) approaches, i.e. signal processing and CASA. Results show that using the hybrid approach outperforms the single approaches.

description: This paper considers the oscillations modeled by a forced Van der Pol generalized oscillator. These oscillations are described by a nonlinear differential equation of the form $ \ddot{x}+x-\varepsilon\left(1-ax^2-b\dot{x}^2\right)\dot{x}=E\sin{Ωt}.$ The amplitudes of the forced harmonic, primary resonance superharmonic and subharmonic oscillatory states are obtained using the harmonic balance technique and the multiple time scales methods. We obtain also the hysteresis and jump phenomena in the system oscillations. Bifurcation sequences displayed by the model for each type of oscillatory states are performed numerically through the fourth-order Runge- Kutta scheme.

description: We present the superconducting and normal state properties of CaPd2Ge2 single crystal investigated by magnetic susceptibility χ, isothermal magnetization M, heat capacity C_p, in-plane electrical resistivity ρand London penetration depth λversus temperature T and magnetic field H measurements. Bulk superconductivity is inferred from the ρ(T) and C_p(T) data. The ρ(T) data exhibit metallic behavior and undergoes a superconducting transition with T_c onset = 1.98 K and zero resistivity state at T_c 0 = 1.67 K. The χ(T) reveal the onset of superconductivity at 2.0 K. For T>2.0 K, the χ(T) and M(H) are weakly anisotropic paramagnetic with χ_ab > χ_c. The C_p(T) confirm the bulk superconductivity below T_c = 1.69(3) K. The superconducting state electronic heat capacity is analyzed within the framework of a single-band α-model of BCS superconductivity and various normal and superconducting state parameters are estimated. Within the α-model, the C_p(T) data and the ab plane λ(T) data consistently indicate a moderately anisotropic s-wave gap with Δ(0)/k_B T_c ~ 1.6, somewhat smaller than the BCS value of 1.764. The relationship of the heat capacity jump at T_c and the penetration depth measurement to the anisotropy in the s-wave gap is discussed.

description: O objetivo deste artigo é discutir se as aulas, chamadas de Vivência Tecnológica, ministradas aos alunos do Ensino Fundamental I, filhos dos beneficiários da indústria de São Paulo, SESI-SP, Brasil, é uma estratégia pedagógica que auxilia os docentes no processo de ensino e aprendizagem e os discentes na autonomia digital. É notória a tendência do uso cada vez mais frequente de computadores e outras tecnologias na educação escolar, por este motivo, a Vivência Tecnológica se propõe a potencializar os aspectos didáticos e metodológicos para o ensino e a aprendizagem. Por essa razão, esta pesquisa objetiva analisar a dinâmica deste momento de “Vivência Tecnológica”, que recebe o subsídio da teoria construtivista e participação direta de duas profissionais (professora dos anos iniciais e analista de informática) e verificar, ainda, se as aulas no Laboratório de Informática e as montagens e programações no Laboratório de Ciências e Tecnologias, com os recursos de blocos de montagem, contribuem para uma abordagem metodológica de ensino, relacionada ao desenvolvimento do pensar, do raciocinar, da resolução de problemas, das práticas de leitura e escrita. Para a realização da pesquisa, optou-se pelo Estudo de Caso, utilizando entrevistas, questionários e observação de sala de aula.

description: We present vortex solutions for the homogeneous two-dimensional Bose-Einstein condensate featuring dipolar atomic interactions, mapped out as a function of the dipolar interaction strength (relative to the contact interactions) and polarization direction. Stable vortex solutions arise in the regimes where the fully homogeneous system is stable to the phonon or roton instabilities. Close to these instabilities, the vortex profile differs significantly from that of a vortex in a nondipolar quantum gas, developing, for example, density ripples and an anisotropic core. Meanwhile, the vortex itself generates a mesoscopic dipolar potential which, at distance, scales as 1/r^2 and has an angular dependence which mimics the microscopic dipolar interaction.

description: O reconhecimento da importância das técnicas de dança na formação de bailarinos e a necessidade de atualizar conceitos, partilhar saberes, memórias e experiências, serviram de catalisadores para a reflexão sobre a temática.
Reflete-se sobre as técnicas de dança enquanto meio de treino do corpo e transmissão de saberes através da revisitação de alguns autores que se entendeu de relevância.
Defende-se a ideia de que um bailarino de qualidade passa, por processos de aprendizagem, expressão e representação em que o corpo é o principal agente e justifica-se a incontornabilidade das técnicas de dança na formação de bailarinos como meio de transmissão de saberes e de treino com formalidades e regras que sustentam a dimensão própria e as especificidades que lhes são atribuídas.

description: We apply here the principle of affine symmetry to the nested fullerene cages (carbon onions) that arise in the context of carbon chemistry. Previous work on affine extensions of the icosahedral group has revealed a new organisational principle in virus structure and assembly. We adapt this group theoretic framework here to the physical requirements dictated by carbon chemistry, and show that we can derive mathematical models for carbon onions within this affine symmetry approach. This suggests the applicability of affine symmetry in a wider context in Nature, as well as offering a novel perspective on the geometric principles underpinning carbon chemistry.
