description: Este trabalho busca discutir características e tendências das teses e dissertações produzidas no Brasil voltadas para o Ensino de Ciências nos anos iniciais escolares, especificamente aquelas que buscaram inovar as práticas pedagógicas escolares. Como problema de pesquisa pretende-se investigar quais as inovações pedagógicas que ocorreram nessas pesquisas e que condições de produção favoreceram essas inovações. Foram identificadas 94 dissertações e teses desde a primeira defesa ocorrida em 1972 até 2011. Em relação ao ano de defesa, houve um sensível crescimento da produção ao longo dos anos: 4 pesquisas defendidas entre 1972 e 1981; 8 pesquisas de 1982 a 1991; 27 pesquisas de 1992 a 2001; e 55 pesquisas de 2002 a 2011. Em relação à área de conteúdo, notamos o predomínio das pesquisas que abordaram o ensino de Ciências sem especificar temas ou conteúdos de alguma área particular e também o crescimento da abordagem de temas correlacionados a educação ambiental. Em relação aos modelos pedagógicos utilizados, destaca fortemente o modelo Construtivista (56,3%), seguido do modelo Sociocultural (30,8%) e dos modelos Ciência-Tecnologia-Sociedade, Redescoberta e Tecnicista (4,2% cada).

description: Clinical History: A 37-year-old female who was 14 weeks gestation presented with severe symptomatic hypertension (200/98). The current pregnancy was initiated with assisted fertility in the form of in-vitro fertilisation (IVF). Treatment was initiated according to the Royal College of Obstetricians and Gynaecologists (RCOG) guidelines with a combination of labetalol, methyldopa and hydralazine. Treatment with spironolactone was contra-indicated due to the risk of ambiguous genitalia in foetus[1]. The patient had no previous history of hypertension. Targets biochemical blood and urine markers were performed to search for a cause of secondary hypertension.

description: The spreading of evolutionary novelties across populations is the central element of adaptation. Unless population are well-mixed (like bacteria in a shaken test tube), the spreading dynamics not only depends on fitness differences but also on the dispersal behavior of the species. Spreading at a constant speed is generally predicted when dispersal is sufficiently short-ranged. However, the case of long-range dispersal is unresolved: While it is clear that even rare long-range jumps can lead to a drastic speedup, it has been difficult to quantify the ensuing stochastic growth process. Yet such knowledge is indispensable to reveal general laws for the spread of modern human epidemics, which is greatly accelerated by aviation. We present a simple iterative scaling approximation supported by simulations and rigorous bounds that accurately predicts evolutionary spread for broad distributions of long distance dispersal. In contrast to the exponential laws predicted by deterministic "mean-field" approximations, we show that the asymptotic growth is either according to a power-law or a stretched exponential, depending on the tails of the dispersal kernel. More importantly, we provide a full time-dependent description of the convergence to the asymptotic behavior which can be anomalously slow and is needed even for long times. Our results also apply to spreading dynamics on networks with a spectrum of long-range links under certain conditions on the probabilities of long distance travel and are thus relevant for the spread of epidemics.

description: É feita uma retrospetiva da história do Clube do Ensino Experimental das Ciências (CEEC) do Agrupamento de Escolas Fernão de Magalhães, enquanto espaço não formal de promoção de ciência e tecnologia. Desde a sua criação, em julho de 2006, que este Clube é um local de práticas educativas onde os alunos podem realizar atividades laboratoriais e discutir assuntos relacionados com ciência e tecnologia. As práticas abrangem, por exemplo, atividades ilustrativas e investigativas, atividades prático-laboratoriais do programa de Física e Química A, preparação das Olimpíadas de Física e Química, modelação computacional, laboratórios virtuais e a participação em projetos/programas de ciência. Contudo, as atividades preferidas dos alunos são as ilustrativas, sendo algumas delas apresentadas à comunidade na Feira da Ciência/Laboratório Aberto da Escola.

A metodologia utilizada no CEEC passa pela diversificação das atividades de modo a satisfazer a curiosidade, as necessidades, os interesses e as expetativas dos alunos.

Finalmente, apresenta-se um estudo comparativo das classificações internas de frequência e das classificações obtidas no Exame Nacional dos alunos do Agrupamento que frequentaram o CEEC e dos alunos do Agrupamento que não o frequentaram, a fim de inferir acerca da influência das atividades desenvolvidas no Clube nestas classificações.

description: We re-investigate the magnetically frustrated, {\it diamond-lattice-antiferromagnet} spinels FeAl$_2$O$_4$ and MnAl$_2$O$_4$ using magnetization measurements and diffuse scattering of polarized neutrons. In FeAl$_2$O$_4$, macroscopic measurements evidence a "cusp" in zero field-cooled susceptibility around 13~K. Dynamic magnetic susceptibility and {\it memory effect} experiments provide results that do not conform with a canonical spin-glass scenario in this material. Through polarized neutron scattering studies, absence of long-range magnetic order down to 4~K is confirmed in FeAl$_2$O$_4$. By modeling the powder averaged differential magnetic neutron scattering cross-section, we estimate that the spin-spin correlations in this compound extend up to the third nearest-neighbour shell. The estimated value of the Landé $g$ factor points towards orbital contributions from Fe$^{2+}$. This is also supported by a Curie-Weiss analysis of the magnetic susceptibility. MnAl$_2$O$_4$, on the contrary, undergoes a magnetic phase transition into a long-range ordered state below $\approx$ 40~K, which is confirmed by macroscopic measurements and polarized neutron diffraction. However, the polarized neutron studies reveal the existence of prominent spin-fluctuations co-existing with long-range antiferromagnetic order. The magnetic diffuse intensity suggests a similar short range order as in FeAl$_2$O$_4$. Results of the present work supports the importance of spin-spin correlations in understanding magnetic response of frustrated magnets like $A$-site spinels which have predominant short-range spin correlations reminiscent of the "spin liquid" state.

description: A escassez de água é um dos problemas atuais mais preocupante que a humanidade tem de enfrentar. Cada ser humano tem de assumir a sua responsabilidade individual na resolução deste problema. Para isso é necessário que se tome consciência que a água potável é um recurso finito e que a continuidade da vida está intimamente ligada à sua existência. É neste contexto que surge o presente trabalho de investigação, desenvolvido com alunos do 2º Ciclo do Ensino Básico, tendo como objetivos fundamentais: (i) sensibilizar o aluno para a necessidade de usar a água de forma consciente e sustentável, (ii) avaliar o impacto de uma ação educativa de sensibilização na redução do consumo da água pelos alunos no seu dia-a-dia e (iii) determinar a influência da partilha da sensibilização pelos alunos aos seus agregados familiares, na alteração dos seus padrões de consumo de água. Foi aplicado um inquérito por questionário para detetar os hábitos de consumo e a poupança de água dos alunos e do seu agregado familiar.

Seguiu-se uma ação educativa de sensibilização, que lhes permitiu refletir sobre os seus verdadeiros gastos de água, repensar os seus hábitos e sentir a necessidade de preservar a água. Após essa ação, foi verificada, através da aplicação do mesmo questionário, a redução do consumo de água e a adoção de mais medidas de poupança por parte dos alunos e respetivos agregados familiares.

Pôde-se verificar que a turma reduziu em cerca de 36% o seu consumo de água com o autoclismo e com os banhos, o que se traduziu numa poupança de 144 443 litros de água por semana.

Exact dynamical coarse-graining without time-scale separation

Year: 2014
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: A family of collective variables is proposed to perform exact dynamical coarse-graining even in systems without time scale separation. More precisely, it is shown that these variables are not slow in general but they satisfy an overdamped Langevin equation that statistically preserves the sequence in which any regions in collective variable space are visited and permits to calculate exactly the mean first passage times from any such region to another. The role of the free energy and diffusion coefficient in this overdamped Langevin equation is discussed, along with the way they transform under any change of variable in collective variable space. These results apply both for systems with and without inertia, and they can be generalized to using several collective variables simultaneously. The view they offer on what makes collective variables and reaction coordinates optimal breaks from the standard notion that good collective variable must be slow variable, and it suggests new ways to interpret data from molecular dynamic simulations and experiments.

description: This paper introduces Q-Epsilon (Q-ε), a structured energy framework that replaces probability with deterministic wave evolution. By applying UMEC-Q, a revolutionary entropy-weighted computation model, this work demonstrates that quantum wavefunctions do not collapse randomly but instead follow precisely structured energy redistributions.

This is not a speculative paper, it is a mathematically derived resolution to the deepest paradoxes in quantum mechanics. Built on previous research in Gravitational Field Measurements and UMEC - Non Iterative Computation, this paper eliminates the need for probability postulates, providing a new governing equation for quantum mechanics based entirely on structured energy modulation within Q-ε.

If this model is correct, then the entire probabilistic interpretation of quantum mechanics collapses. Instead of randomness, quantum behavior follows strict deterministic resonance patterns, measurable in high-precision quantum experiments.

This is just the first paper on Q-Epsilon, establishing its role in quantum mechanics. Its broader implications—including its connection to fundamental forces, constants, and the restructuring of physics, will be explored in New Foundation for Understanding Reality. This work is a critical piece of the ongoing PAN Framework, which aims to redefine the foundations of physics.

description: Lernende werden in den aktuellen hochschulpolitischen Debatten und wissenschaftlichen Diskursen rund um die Chancen und Herausforderungen des digitalen Wandels zu wenig eingebunden. Auf diese Weise kommt ihnen zumeist nur die Rolle von passiven Teilnehmenden zu. Für innovative Ideen und neue Perspektiven gibt es bisweilen weder die Offenheit des Prozesses, noch eine grundlegende Bereitschaft von den Nutzer*innen her zu denken und zu handeln. Einige hochschulische und außerhochschulische Strukturen, Projekte und Initiativen zeigen jedoch deutschland- und europaweit, wie innovativ und aktiv, aber auch kritisch-konstruktiv, Studierende auf verschiedenen Ebenen Digitalisierungsprozesse mitgestalten wollen und können – wenn sie die Möglichkeiten erhalten. Aus diesem Grund hat das Hochschulforum Digitalisierung die Initiative #DigitalChangeMaker ins Leben gerufen und bietet Studierenden die Chance, Hochschulbildung gemeinsam neu, kreativ und innovativ zu denken und Diskurse aktiv in einer spannenden Community von Expert*innen unterschiedlicher Hintergründe mitzugestalten. Als zentraler Anker für diese Initiative hat sich im September 2018 die studentische Zukunfts-AG #DigitalChangeMaker konstituiert. Dieses Kernteam von 12 studentischen Expert*innen aus ganz Deutschland möchte neue Möglichkeitsräume für engagierte junge Menschen schaffen, die Zukunft ihrer digital geprägten Lernwelten zu diskutieren und dabei eigene Wege zu finden, diese Zukunft aktiv mitzugestalten. Dabei werden auch eigene Fragestellungen, Forderungen, Lösungen und Beteiligungsmodelle entwickelt und gleichzeitig bereits bestehende Beispiele guter Praxis gesammelt, sowie stärker sichtbar gemacht. Mit diesem Positionspapier soll der Diskurs zur Digitalisierung in der Hochschulbildung zum ersten Mal um ein Positionspapier mit einer dezidierten Studierendenperspektive erweitert werden. Die Thesen sind im Rahmen der Austauschformate der studentischen Zukunfts-AG #DigitalChangeMaker des Hochschulforums Digitalisierung entstanden. Sie sind als Impuls zu verstehen, als eine Anregung, die keine abschließende Klärung mit Anspruch auf vollständige Repräsentation aller Studierenden für sich reklamiert. Zielsetzung ist vielmehr, neue Räume für Studierendenbeteiligung zu erschließen und damit auch die Diskussion um eine zeitgemäße Hochschulbildung im digitalen Zeitalter schrittweise immer stärker zu öffnen.

description: Além de pouco estudada, a motivação para aprender química tem sido enfocada como fenômeno do campo afetivo e externo à aprendizagem. Visando contribuir para um enfoque da motivação enquanto fenômeno subjetivo e complexo, o presente artigo apresenta dois estudos de caso da motivação de estudantes cursando o segundo ano do ensino médio. Do estudo de cada caso emergem configurações de sentidos subjetivos singulares, que envolvem a relação com familiares, professores, colegas e o próprio conhecimento. A motivação para estudar química aparece como uma produção subjetiva resultante de toda a história escolar e extra-escolar de cada sujeito, o que implica uma relação muitas vezes contraditória dos níveis subjetivos social e individual.

description: We investigate Josephson junctions on the surface of a three-dimensional topological insulator in planar, step, and edge geometries. The elliptical nature of the Dirac cone representing the side surface states of the topological insulator results in a scaling factor in the Josephson current in a step junction as compared to the planar junction. In edge junctions, the contribution of the Andreev bound states to the Josephson current vanishes due to spin-momentum locking of the surface states. Furthermore, we consider a junction with a ferromagnetic insulator between the superconducting regions. In these ferromagnetic junctions, we find an anomalous finite Josephson current at zero phase difference if the magnetization is pointing along the junction (and perpendicular to the Josephson current). An out-of-plane magnetization with respect to the central region of the junction opens up an exchange gap and leads to a non-monotonic behavior of the critical Josephson current for sufficiently large magnetization as the chemical potential increases.

description: This paper introduces the Universal Mathematical Entropy Computation (UMEC) framework, a major advancement in non-iterative mathematics within the Pan Framework. By eliminating iterative refinement, UMEC enables immediate stability, global optimization, and high-precision numerical extraction, addressing fundamental limitations in traditional numerical methods. That is to say, UMEC resolves computational problems in a single step! "1"

Through entropy-weighted transformations, universal weighting functions, and harmonic resonance principles, UMEC establishes a self-resolving computational methodology applicable to fluid dynamics, optimization, quantum mechanics, and cryptography. This framework consists of three major variants:

UMEC-D: Deterministically stabilizes chaotic and nonlinear systems without iterative solvers.

UMEC-O: Resolves global optimization problems in a single step, bypassing local minima traps.

UMEC-Q: Extracts high-precision numerical values instantly, transforming high-speed computation.

As a foundational component of the Pan Framework, aspects of UMEC will directly connect to future physics papers, as well as the previously published "Gravitational Field Measurements by Pan"

description: Our auxiliary modulation coordinate framework builds upon established quantum field theory principles developed by Weinberg and Peskin & Schroeder. Weinberg's comprehensive treatment of field theory provides essential mathematical tools for handling field propagation across dimensions, which we extend by adding the modulation dimension ε. While Weinberg focuses on standard spacetime, our approach introduces a third dynamic axis (modulation), but utilizes similar differential equation structures. The algebraic methods from Peskin & Schroeder's work—particularly their treatment of field oscillators and propagators—provide technical foundations that we adapt to handle modulation propagation.The deterministic underpinnings of our approach connect to Bohm's hidden variables theory, though with crucial differences. Where Bohm introduces a separate "pilot wave" to guide particles, our theory identifies modulation itself as the guiding principle, with no separate hidden variables needed. Similarly, while 't Hooft's cellular automaton interpretation shares our deterministic goals, his discrete computational model contrasts with our continuous field-based approach. Both theories aim to restore determinism to quantum mechanics, but through fundamentally different mechanisms.Carroll's recent work on how classical reality emerges from quantum fields provides a valuable contemporary perspective that parallels our own. Carroll argues that quantum field theory underlies everyday reality but focuses primarily on decoherence as the emergence mechanism. In contrast, our theory identifies modulation coherence as the key organizing principle, offering a more fundamental explanation for emergence.

description: Vacuum energy of quarks participates in the pressure balance at the temperature transition T_c and defines the dependence of T_c on m_q. We first check this dependence in absence of magnetic fields eB vs known lattice data, and then take into account the known strong dependence of the quark condensate on eB. The resulting function T_c(eB, m_q) is valid for all eB, m_q< \sqrtσand explains the corresponding lattice data.

description: Este trabalho é resultado de um projeto de Iniciação científica do Programa Institucional de Bolsas de Iniciação Científica [PIBIC] do Conselho Nacional de Desenvolvimento Científico e Tecnológico [CNPq],  constituindo parte de um projeto maior apoiado pela Fundação de Amparo à Pesquisa do Estado de São Paulo [FAPESP] (2009/54874-6) e pelo CNPq (407257/2012-8). O trabalho teve como objetivo investigar a mediação do professor em aulas de Física do ensino médio, com fundamento na teoria sócio-histórica de Vygotsky, permitindo identificar as possibilidades de redimensionar as práticas pedagógicas do professor por meio de uma pesquisa intervenção. No presente artigo foram analisados os diferentes aspectos do discurso em sala de aula, a partir da estrutura analítica proposta por Mortimer e Scott (2002), apoiados em Vygotsky (1984) e Bakhtin (1986). Esta estrutura analítica fundamenta-se nos diversos registros semióticos criados para comunicação e representação da realidade e ao trânsito entre as diversas representações proposto por Duval (2009). As aulas foram gravadas em vídeo, sendo destacados e analisados dois episódios, o primeiro em uma aula regular e o segundo, de uma aula com intervenção. Comparando os episódios 1 e o 2 observou-se uma mudança da postura do professor e dos alunos. Embora nos dois episódios a abordagem comunicativa seja interativa/de autoridade, verificou-se que no segundo episódio o professor busca explorar mais as ideias dos alunos, alterando-se também os padrões de interação. Observou-se que a diversificação da representação de um mesmo objeto aumentou a capacidade cognitiva dos alunos possibilitando a apropriação do conhecimento. As mudanças ocorridas possibilitaram a melhoria da aprendizagem quando se estabelecem a conversão entre os diferentes registros semióticos.

description: Este trabalho constitui parte de um projeto maior apoiado pela FAPESP (2009/54874-6) que tem como foco o processo discursivo na construção do conhecimento que ocorre no contexto das escolas. A partir do conceito de abordagem comunicativa (Mortimer & Scott, 2003) analisamos como o professor trabalha o discurso na sala de aula com seus alunos.  Na construção dos dados, as aulas de física com a duração de 50 minutos cada  foram gravadas  em vídeo. As salas de aula do 1.º ano do ensino médio de escola pública do interior do Estado de São Paulo/Brasil eram constituídas de 22 alunos. Nesta pesquisa foi feita a análise dos processos discursivos de um episódio ocorrido durante as aulas cujo tema foi queda livre. A sequência analisada permite apontar que os discursos observados são de modo heterogêneo, sendo direcionados como discurso interativo/de autoridade, indicando que o professor, em suas questões, demanda um modo correto de resposta dos alunos que leva à monologização do discurso.

description: The Josephson effect is a kind of macroscopic quantum phenomenon that supercurrent flows through a Josephson junction without any voltage applied. We predict a novel vortex-state-mediated Josephson effect in an SNS Josephson junction supporting vortices. The vortex-state-mediated supercurrent is enhanced or reduced significantly in magnitude depending on the junction length, and exhibits several steps with the number of effective propagating channels in current-phase evolution at zero temperature. At finite temperatures, these supercurrent steps persist in the short junction limit, and develop into sawtooth oscillations if the junction length becomes comparable to the coherence length $ξ=\hbar v_F/Δ$ of the superconductor, and in later case a supercurrent reversal can be observed. These findings may provide a smoking-gun signature of vortex bound states in superconductors and promise possible applications in future Josephson devices.

description: Pouca atenção tem sido dada aos aspectos subjetivos do processo de ensino e aprendizagem. Entretanto, a maneira como o professor conduz sua prática depende de configurações de sentidos subjetivos constituídos ao longo de sua história. Assim, apesar de suas diretrizes gerais, o trabalho com projetos apresentará diferentes ênfases, em função dos motivos que tem o docente para trabalhar com essa pedagogia. No presente estudo, a partir dos conceitos da Teoria da Subjetividade de González Rey, analisamos o relato das experiências de uma professora com a Pedagogia de Projetos, refletindo sobre como tais experiências se configuram subjetivamente para ela e o que a motiva a ensinar desta maneira. As informações analisadas foram obtidas através de entrevistas e conversas informais. A partir dos resultados, compreendemos que os sentidos subjetivos da professora relacionados ao trabalho com projetos, articulavam sua concepção de ensino e de ciências, suas experiências anteriores na pós-graduação e na gestão escolar, suas vivências e discussões curriculares com outros docentes da família, além da valorização de sua própria autonomia e da autonomia dos estudantes. Tais sentidos subjetivos, construídos pela professora em vários contextos, passaram a constituir a singularidade de sua motivação para trabalhar com projetos.

description: We review a success story regarding Bayesian inference in fisheries management in the Baltic Sea. The management of salmon fisheries is currently based on the results of a complex Bayesian population dynamic model, and managers and stakeholders use the probabilities in their discussions. We also discuss the technical and human challenges in using Bayesian modeling to give practical advice to the public and to government officials and suggest future areas in which it can be applied. In particular, large databases in fisheries science offer flexible ways to use hierarchical models to learn the population dynamics parameters for those by-catch species that do not have similar large stock-specific data sets like those that exist for many target species. This information is required if we are to understand the future ecosystem risks of fisheries.

description: A function $f\colon\mathbb R\to\mathbb R$ is called \emph{$k$-monotone} if it is $(k-2)$-times differentiable and its $(k-2)$nd derivative is convex. A point set $P\subset\mathbb R^2$ is \emph{$k$-monotone interpolable} if it lies on a graph of a $k$-monotone function. These notions have been studied in analysis, approximation theory etc. since the 1940s. We show that 3-monotone interpolability is very non-local: we exhibit an arbitrarily large finite $P$ for which every proper subset is $3$-monotone interpolable but $P$ itself is not. On the other hand, we prove a Ramsey-type result: for every $n$ there exists $N$ such that every $N$-point $P$ with distinct $x$-coordinates contains an $n$-point $Q$ such that $Q$ or its vertical mirror reflection are $3$-monotone interpolable. The analogs for $k$-monotone interpolability with $k=1$ and $k=2$ are classical theorems of Erdős and Szekeres, while the cases with $k\ge4$ remain open. We also investigate the computational complexity of deciding $3$-monotone interpolability of a given point set. Using a known characterization, this decision problem can be stated as an instance of polynomial optimization and reformulated as a semidefinite program. We exhibit an example for which this semidefinite program has only doubly exponentially large feasible solutions, and thus known algorithms cannot solve it in polynomial time. While such phenomena have been well known for semidefinite programming in general, ours seems to be the first such example in polynomial optimization, and it involves only univariate quadratic polynomials.

description: A oxidação de lípidos constitui a principal causa de degradação da carne, levando à perda do seu valor nutritivo. A quantidade intramuscular de agentes oxidantes é finamente regulada por agentes redutores endógenos como o ascorbato ou catalases que decrescem rapidamente durante a conversão do músculo em carne. Assim, os níveis de catalase ou o conteúdo lipídico podem ser bons indicadores da qualidade da carne. Nesse contexto, o desenvolvimento do estudo aqui descrito possibilitou aos alunos de uma turma-piloto da unidade curricular Bioquímica I do Mestrado Integrado em Medicina Veterinária, da Universidade de Évora, participarem ativamente no planeamento e na preparação de uma atividade laboratorial, com o objetivo de determinar marcadores nutricionais e de peroxidação lipídica da carne de Meleagris ocellata, Sus scrofa domesticus e Bos taurus. Os resultados obtidos na quantificação gravimétrica de lípidos, espetrométrica do colesterol e catalases, mobilizaram os alunos para uma aproximação bioquímica à caraterização de carnes de diferente origem animal. A avaliação das competências desenvolvidas pelos alunos, observacional e por resposta a questionários antes e após a realização das diferentes etapas da aula, revelou que estes ampliaram o seu grau de cumprimento em termos de destreza laboratorial, aquisição, leitura e interpretação de resultados, adquirindo desse modo uma aprendizagem significativa.
