Astros no rock: uma perspectiva sociocultural no uso da canção na educação em ciências

A incorporação de elementos da cultura primeira do estudante no processo de ensino-aprendizagem foi defendida pelo pedagogo francês Georges Snyders (1988) em sua obra \"A Alegria na Escola\". Esta pesquisa contribuiu com essa interface, identificando, no discurso de canções do rock n\' roll, elementos textuais que possibilitem reflexões no âmbito conceitual, epistemológico e sociopolítico sobre a exploração do espaço. O objeto de estudo neste trabalho são canções do período entre as décadas de 1960 e 1970 que possuem representações sobre a astronomia e as missões espaciais. O uso do rock justificou-se pelo fato de temas sobre exploração espacial aparecerem no trabalho de diversos artistas desse gênero musical, permitindo reflexões em nível conceitual, epistemológico e sociopolítico sobre a ciência, a tecnologia e suas relações com a sociedade e o ambiente. Além disso, identificamos que tanto o rock quanto as missões espaciais foram fenômenos culturais que dependeram em sua gênese dos avanços da tecnologia e da ciência e tiveram sua repercussão na sociedade através de processos midiáticos. Essas canções foram selecionadas entre os diversos gêneros de rock, e analisadas a partir de referenciais semiodiscursivos. As atividades foram aplicadas em situações formais de ensino - ensino médio e ensino superior -, em formação continuada de professores e projetos de ensino não formal na escola. No processo de ensinoaprendizagem, foram desenvolvidas atividades que envolviam leitura-comentada da canção, identificando na letra, melodia e harmonia, aspectos que evidenciavam um discurso crítico sobre a ciência e sua relação com a sociedade e o ambiente. Essas atividades envolveram três instâncias: Elaboração, Aplicação e Análise. Como referencial norteador dessas etapas, nos valemos das teorias socioculturais de Vigotski (2001), Snyders (1988) e Freire (2013).

Study and evaluation of several cache replacement policies on a commercial MIPS Processor

Actualmente, el rendimiento de los computadores es un tema candente. Existen importantes limitaciones físicas y tecnológicas en los semiconductores de hoy en día, por lo que se realiza un gran esfuerzo desde las universidades y la industria para garantizar la continuidad de la ley de Moore. Este proyecto está centrado en el estudio de la cache y la jerarquía de memoria, uno de los grandes temas en la materia. Para ello, hemos escogido MIPSfpga, una plataforma hardware abierta de Imagination Technologies, lo que nos ha permitido implementar y testear diferentes políticas de reemplazamiento como prueba de concepto, demostrando, además, las bondades de la plataforma.

Self-heating and deicing conductive cement. Experimental study and modeling

This research studies the self-heating produced by the application of an electric current to conductive cement pastes with carbonaceous materials. The main parameters studied were: type and percentage of carbonaceous materials, effect of moisture, electrical resistance, power consumption, maximum temperature reached and its evolution and ice melting kinetics are the main parameters studied. A mathematical model is also proposed, which predicts that the degree of heating is adjustable with the applied voltage. Finally, the results have been applied to ensure that cementitious materials studied are feasible to control ice layers in transportation infrastructures.

Kinetic study and thermal decomposition behavior of viscoelastic memory foam

A systematic investigation of the thermal decomposition of viscoelastic memory foam (VMF) was performed using thermogravimetric analysis (TGA) to obtain the kinetic parameters, and thermogravimetric analysis coupled to Fourier Transformed Infrared Spectrometry (TGA-FTIR) and thermogravimetric analysis coupled to Mass Spectrometry (TGA-MS) to obtain detailed information of evolved products on pyrolysis and oxidative degradations. Two consecutive nth-order reactions were employed to correlate the experimental data from dynamic and isothermal runs performed at three different heating rates (5, 10 and 20 K/min) under an inert atmosphere. On the other hand, for the kinetic study of the oxidative decomposition, the data from combustion (synthetic air) and poor oxygen combustion (N2:O2 = 9:1) runs, at three heating rates and under dynamic and isothermal conditions, were correlated simultaneously. A kinetic model consisting of three consecutive reactions presented a really good correlation in all runs. TGA-FTIR analysis showed that the main gases released during the pyrolysis of VMF were determined as ether and aliphatic hydrocarbons, whereas in combustion apart from the previous gases, aldehydes, amines and CO2 have also been detected as the main gases. These results were confirmed by the TGA-MS.

A catechism geographical, historicall and chronologicall

Notebook of unlined pages holding a handwritten copy of Tutor Flynt's "Catechism" copied by Harvard student Hull Abbot (1702-1774, Harvard AB 1720). The volume lists questions and accompanying answers on various academic subjects.

A catechism geographicall, historical and chronologicall 1719

Notebook of unlined pages with paper marbled cover holding a handwritten copy of Tutor Flynt's "Catechism" likely copied by Harvard student John Wolcott in 1719. The volume lists questions and accompanying answers on various academic subjects. On the last page, the inscription "John Wolcott [the name is crossed over] his geography, 1719" indicates Wolcott (1702-1747), a member of the Harvard class of 1721, copied the book.

Short nomenclator or vocabular in English and Hebrew: composed alphabetically for the use and benefit of my pupils in particular and for the advantage of those who are desirous to obtain the knowledge of the Hebrew tongue in general, which may be that great help to understand not only ye sacred oracles in their original, but even any Jewish author (so far as concern owns) as also it may give great insight in ye tongue to those, as to compose it, a work altogether new, [ca. 1735]

Headed on the first page with the words "Nomenclatura hebraica," this handwritten volume is a vocabulary with the Hebrew word in the left column, and the English translation on the right. While the book is arranged in sections by letter, individual entries do not appear in strict alphabetical order. The small vocabulary varies greatly and includes entries like enigma, excommunication, and martyr, as well as cucumber and maggot. There are translations of the astrological signs at the end of the volume. Poem written at the bottom of the last page in different hand: "Women when good the best of saints/ that bright seraphick lovely/ she, who nothing of an angel/ wants but truth & immortality./ Verse 2: Who silken limbs & charming/ face. Keeps nature warm."

Enchiridion ethicum ad theses contractiores redactum in usum pupillorum, p. D. J. L., 1694

Forty-six-page notebook in modern hardcover binding containing John Leverett's edited version of Henry More's "Enchiridion ethicum" transcribed in Latin in 1694. The last page of the document includes entries in Leverett's hands: "Colom // January 17 1690/1," "Winth // January 31 1692/3", and "Vaug // Marty 10 1695/6." The inscriptions and notes likely refer to Benjamin Colman (Harvard AB 1692), Adam Winthrop (Harvard AB 1694), and George Vaughn (Harvard AB 1696).

Grammatica literarum, syllabarum, verborum, & sententiarum, 1754

One-page handwritten list of 20 numbered theses in Latin presumed to be copied by Bela Lincoln. The document is signed "Lincoln 1754." The document title translates as "Grammar of letters, syllables, words, and sentences" and includes all of the nine theses listed in the "Theses Grammaticae" section of the 1754 Commencement broadside.

Student lecture notes of Benjamin Peirce, 1797-1798

This collection contains approximately twenty-three handwritten lecture summaries on six leaves made by Harvard undergraduate Benjamin Peirce between September 1797 and November 22, 1798. The summaries generally provide a few sentences describing the topic covered and primarily pertain to lectures on English grammar delivered by Eliphalet Pearson, the Hollis Professor of Hebrew and other Oriental Languages. There are also summaries for single lectures by David Tappan, the Hollis Professor Divinity; Samuel Webber, the Hollis Professor of Mathematics and Natural Philosophy; and John Snelling Popkin, the Greek Tutor from 1795 to 1798, and later the Eliot Professor of Greek Literature. There is also an undated summary of a lecture by Benjamin Waterhouse, the Hersey Professor of Theory and Practice of Physic.
