Determinação do teor alcoólico de vodcas: uma abordagem multidisciplinar no ensino da física, química e matemática

In this paper, it is proposed an experimental activity to be developed with high school students, addressing the concepts of density and surface tension from a multidisciplinary approach among Physics, Chemistry and Mathematics. In this proposal, students are challenged to determine the alcohol content of vodkas from intensive physical properties of liquids. Two calibration curves were obtained, one for density and another for surface tension as a function of ethanol concentration in water. The alcohol levels obtained from these properties were very close to the values given by manufacturers, due the similarity of these beverages with ethanol-water binary mixtures.

Protótipo de uma atividade experimental para o estudo da cinemática realizada remotamente

Este artigo apresenta uma avaliação de um protótipo relativo a um experimento de cinemática que pode ser controlado remotamente via internet. Para tanto, utilizamos microcontroladores da família PIC, visando controlar a velocidade de carrinhos de brinquedo. O intuito foi investigar a possibilidade de se construir um laboratório de Ensino de Física totalmente controlado remotamente com vistas a apoiar cursos de formação inicial e continuada de professores ministrados a distância. A avaliação do protótipo foi realizada por 15 alunos de um curso presencial de Graduação em Física, no âmbito da disciplina de Instrumentação para o Ensino da Física. Os resultados apontam para a viabilidade da utilização desse recurso.

Qualidade de vida e atividade física em idosos

The aims of this literature review were to analyze the relationship between elderly quality of life - by means of the verification of the major measure instruments - with the physical activity, the sensibility of these questionnaires to the physical activity and the relationship between the type of physical activity and the quality of life in older persons. Comparisons of papers selected by the key words quality of life, exercise, and aging, reveal the components of quality of life assessed by the WHOQOL-BREF and SF-36 questionnaires. Based on the searched literature, we can conclude that: (i) active elderly seems to have better subjective perception of their quality of life than non active older persons; (ii) experimental studies did not showed strong evidence about the effects of physical exercise in the subjective perception of quality of life; (iii) none of the questionnaires is sensible to the practice of physical activity; (iv) the studies' results about the relationship between the type of physical activity and the elderly quality of life are inconclusive

On the quantumness of correlations in nuclear magnetic resonance

Nuclear magnetic resonance (NMR) was successfully employed to test several protocols and ideas in quantum information science. In most of these implementations, the existence of entanglement was ruled out. This fact introduced concerns and questions about the quantum nature of such bench tests. In this paper, we address some issues related to the non-classical aspects of NMR systems. We discuss some experiments where the quantum aspects of this system are supported by quantum correlations of separable states. Such quantumness, beyond the entanglement-separability paradigm, is revealed via a departure between the quantum and the classical versions of information theory. In this scenario, the concept of quantum discord seems to play an important role. We also present an experimental implementation of an analogue of the single-photon Mach-Zehnder interferometer employing two nuclear spins to encode the interferometric paths. This experiment illustrates how non-classical correlations of separable states may be used to simulate quantum dynamics. The results obtained are completely equivalent to the optical scenario, where entanglement (between two field modes) may be present.

Correlation Between Molecular Conformation, Packing, and Dynamics in Oligofluorenes: A Theoretical/Experimental Study

Fluorene-based systems have shown great potential as components in organic electronics and optoelectronics (organic photovoltaics, OPVs, organic light emitting diodes, OLEDs, and organic transistors, OTFTs). These systems have drawn attention primarily because they exhibit strong blue emission associated with relatively good thermal stability. It is well-known that the electronic properties of polymers are directly related to the molecular conformations and chain packing of polymers. Here, we used three oligofluorenes (trimer, pentamer, and heptamer) as model systems to theoretically investigate the conformational properties of fluorene molecules, starting with the identification of preferred conformations. The hybrid exchange correlation functional, OPBE, and ZINDO/S-CI showed that each oligomer exhibits a tendency to adopt a specific chain arrangement, which could be distinguished by comparing their UV/vis electronic absorption and C-13 NMR spectra. This feature was used to identify the preferred conformation of the oligomer chains in chloroform-cast films by comparing experimental and theoretical UV/vis and C-13 NMR spectra. Moreover, the oligomer chain packing and dynamics in the films were studied by DSC and several solid state NMR techniques, which indicated that the phase behavior of the films may be influenced by the tendency that each oligomeric chain has to adopt a given conformation.
