Aproxima??es no ensino de f?sica: o estudo do p?ndulo simples
No full textThe use of approximations in Physics is very common and necessary to enable our
understanding of fundamental aspects of the nature working. The purpose of this work is to
clarify that the use of approximations is not a logical crime as long as the limitations inherent
to these approximations are clear to the investigator. We address the approach used in the study
of a simple pendulum, where it is adopted, for small oscillations ???? ? ?, in order to facilitate
its quantitative investigation. An experimental apparatus was developed to collect empirical
data, some possible correlations of the pendulum period with its constructive characteristics
were analyzed, limiting the study to the direct dependence of the period with its length, thus
achieving an empirical equation, capable of performing period predictions for a given length.
In addition, the study of error theory was did in order to clarify its use in experimental studies,
showing its importance at the time of analyzing the data obtained from an experiment, seeking
to clarify the reason why some terms of minor importance can or cannot be left aside in the
study of a physical phenomenon. Finally, it was sought through this approach to treat Physics
not as an exact science, but as a science of good approximations, which makes it even more
instigating, as a natural philosophy.O uso de aproxima??es em F?sica ? muito corriqueiro e necess?rio para possibilitar nossa

No full textMongolian translation of Subhashita by Mergen gegeen Luvsandambiijaltsan should be considered as one of the most valuable monuments of the Mongolian language in the 18th century. Unfortunately, the translation has not been studied as well as it should. The author has attempted to study and pursue some words while dividing the work into the following parts: Sanskrit words, Tibetan words, loan words and archaic words
Transformation of Yakut Heroic Epos (by Material of Olonkho of B. A. Alekseyev “Erbechtay Mergen”)
No full textThe article is devoted to the transformation of the Yakut heroic epos on the example of Olonkho of B. A. Alekseyev “Erbechtay Mergen,” which was recorded by him and the folklorist-collector S. I. Bolo during the Vilyuisk expedition in 1938. The relevance of the work is determined by the increased interest in the transformation processes of the traditional culture of the Yakuts under the influence of the socio-cultural environment. The novelty of the study is that for the first time the local Olonkho text is studied as an object of transformation. Olonkho manuscript and the peculiarities of its recording are given. It is reported that in 2017 the author of the article prepared the Olonkho text for publication. The article establishes fabulous elements, demythologization, the influence of Russian culture as the cause of changes in Olonkho. As the author of the article shows, this Olonkho is characterized by cumulative actions of the characters, as in fairy tales. It is noted that the rivalry and strife of relatives enhance the domestic nature of the relationship between the characters and push the heroic image into the background. It is reported that due to demythologization the mythological motifs and images have become rare in Olonkho of B. A. Alekseyev. The author also points out that under the influence of Russian culture there have been some changes: a lot of words are borrowed from the Russian language, the names of Russian cities, the pantheon of deities began to include Christian images, there is a mixture of the image of Baba Yaga and abaasa women, there are images of Russian girls, etc
LEI DO FAROL BAIXO E O CONSUMO DE ENERGIA: POSSIBILIDADES DE PRÁTICAS EDUCATIVAS EM SALA DE AULA
No full textNo ano de 2016, a Câmara dos Deputados aprovou uma Lei que obriga o uso de faróis baixos nas rodovias durante o dia. Com intuito de problematizar e avaliar os impactos socioambientais e socioeconômicos dessa lei construímos um aparato experimental que relaciona o consumo de energia das lâmpadas dos automóveis com o consumo de combustível gerado por ela. Assim, a prática educativa experimental, faz parte do tema Energia e vida, foi implementada em um dos componentes curriculares de um curso de Licenciatura em Física, proporcionando a discussão dialógico-problematizadora acerca da questão da qual emergiu a investigação: com a lei que obriga os veículos a trafegarem com os faróis ligados durante o dia teremos um aumento do consumo de combustível? Essa prática seguiu metodologicamente em acordo com os três momentos pedagógicos e teoricamente seguindo os preceitos da abordagem temática de perspectiva Freire-CTS. Com a realização dessa atividade junto a professores em formação inicial, percebemos que a questão levantada, está inserida em uma problemática contemporânea de cunho sócio-econômico-ambiental pertencente ao mundo vivencial desses, foi pensada como possibilidade de ser trabalhada na Educação Básica, é relevante para a discussão em sala de aula, proporcionando o posicionamento crítico-reflexivo-problematizador, favorecendo a entendimento/construção do conhecimento conceitual
O pêndulo simples como mediador de conceitos e métodos no ensino de Física/ The simple pendulum mediating concepts and methods in teaching of Physics
No full textApresentamos o pêndulo simples como ferramenta capaz de mediar a construção de conceitos e metodologias investigativas relevantes para a Física e seu ensino. Embora abordado à exaustão na literatura correlata, o pêndulo simples e seu potencial qual mediador de conceitos no âmbito de ensino-aprendizagem dos estudantes está aquém de ser exaurido. Ao explorá-lo com auxílio de um software livre para a aquisição e o processamento de dados, o Tracker, permite-se a vivência com tecnologias de informação e comunicação para a construção de dados quantitativos relevantes, tanto em um ambiente de sala de aula quanto em um estudo dirigido. Pretende-se que a exposição desse trabalho venha a estimular o desenvolvimento de atividades experimentais em sala de aula e, para além disso, que venha a ser frutífero no desenvolvimento de aprendizagem crítica das Ciências, de seu contexto (história, implicações sociais, econômicas e culturais) e das suas limitações, viabilizando a construção prática de um ambiente propício à multidisciplinaridade, seja no ensino básico ou superior
Influência de eventos extremos de calor nos fluxos de energia em área agrícola com trigo no sul do Brasil.
No full textOs eventos de calor extremo tem sido reportados com mais frequência nos últimos anos. Entretanto, poucos estudos abordamos efeitos destes eventos sobre os fluxos turbulentos na camada limite atmosférica. Este estudo tem como objetivo investigar ocomportamento anômalo nos fluxos de calor sensível e latente e sua relação com eventos de calor extremo em uma lavoura detrigo no município de Carazinho – RS, no período de inverno. A análise mostrou uma relação entre a intensa advecção de arquente do quadrante norte com o aumento do fluxo de calor latente e a valores negativos do fluxo de calor sensível durante váriosdias consecutivos. Portanto, o evento de calor extremo modifica de forma significativa o padrão esperado para o comportamento dos fluxos superficiais.Número especial 2. XII Workshop Brasileiro de Micrometeorologia
Intertextual Relations in the Sodom and Gomore Novel of Yakup Kadri Karaosmanoğlu
No full textYakup Kadri Karaosmanoğlu, kaleme almış olduğu eserleriyle daima isminden söz ettiren bir yazar olmuştur. Yakup Kadri'nin almış olduğu eğitimler, bulunduğu ortamlar eserlerini yansıyan ana etmenlerdir. Yazarın eserleri, okuyucuya farklı anlam katmanlarının kapılarını aralamaktadır. Bu açıdan Yakup Kadri Karaosmanoğlu kaynakları hakkında akademik bir çalışma bulunmamaktadır. Bu durum onun yazarlığının ve üslubunun anlaşılması açısından bir eksiklik olarak görülmektedir. Bu tezde, Yakup Kadri hakkında yapılan çalışmalardaki söz konusu eksikliği gidermek amacıyla yazarın Sodom ve Gomore romanı metinlerarası ilişkiler kuramı bakımından incelenmiştir. Bu doğrultuda öncelikle metin kavramı tartışılmış ardından metinlerarası kuramı hakkında çalışmalar yapan kuramcıların görüşlerine yer verilmiştir. Ardından Sodom ve Gomore'ın kurgusunda rol oynayan metinler incelenmiştir. Bu noktada Shakespeare'in eserleri, Oscar Wilde'in Dorian Gray'in Portesi, Pierre Loti'nin eserleri, Yunan mitolojisine ait öğeler, Kutsal Metinlere ait parçalar romanın olay örgüsü ve karakter kurgulamasında etkili olduğu görülmüştür. Bu bağlamda romanın içerişinde yer alan metinler ortaya çıkartılmış ve metinlerarasılık bağlamında yeniden yorumlanmıştır. Bu sayede romanın çok sesli bir yapıya sahip olduğu ortaya çıkartılmış ve eserin arka planında yer alan kaynaklar ortaya çıkartılmıştır.Yakup Kadri Karaosmanoğlu has always been a famous writer with his works. The education life of Yakup Kadri and the environments he lived in are the main factors that reflect his works. The works of the author open the doors of different layers of meaning to the reader. In this respect, there is no academic study on the sources of Yakup Kadri Karaosmanoğlu. This situation is seen as a deficiency in terms of understanding his authorship and style. In this thesis, the author's novel Sodom and Gomorrah has been examined in terms of intertextual relations theory in order to eliminate the said deficiency in the studies on Yakup Kadri. In this direction, firstly the concept of text was discussed, then the views of theorists working on intertextual theory were included. Then, the texts that played a role in the fiction of Sodom and Gomorrah were examined. At this point, it has been seen that Shakespeare's works, Oscar Wilde's Porte of Dorian Gray, Pierre Loti's works, elements of Greek mythology, parts of the holy texts are effective in the plot and character fiction of the novel. In this context, the texts in the novel were revealed and reinterpreted in the context of intertextuality. In this way, it was revealed that the novel has a polyphonic structure and the sources in the background of the work were revealed
Intertextual World of the Novel Sodom and Gomorrah
No full textBu çalışma Yakup Kadri Karaosmanoğlu’nun Sodom ve Gomore romanının metinle-rarası ilişkiler açısından incelenmesi hakkındadır. Eser, adından başlayarak okuru başka metinlere yönlendirmekte ve roman kişilerinden olay örgüsüne, zaman ve mekân ögelerinin kurgulanmasına kadar romanın birçok katmanında bu durumun izleri sürülebilmektedir. Bu doğrultuda çalışmada bir taraftan yazarın metinlerarası kaynaklarının tespit edilmesi, diğer taraftan bu kaynakları kullanma biçimlerinin gün yüzüne çıkarılması amaçlanmıştır. Böylece onun yazarlığının yapıtaşlarından en azından birinin aydınlatılacağı düşünülmüştür. Romana bu bakış açısından yaklaşıl-dığında Kitab-ı Mukaddes dışında da Yunan mitolojisine ait anlatılarla birlikte Batı edebiyatlarına ait birçok metnin romanın yapısında farklı metinlerarası yöntemlerle kullanıldığı görülmüştür. Bu doğrultuda mitolojik anlatılarla birlikte romanın arka katmanlarında rolü olan en belirgin metinlerin Oscar Wilde’ın Dorian Gray’in Portresi, Goethe’nin Faust’u ve William Shaekespeare’in Antonius ve Kleopatra başta olmak üzere birçok oyunu olduğu tespit edilmiş ve bunların romanın yapısındaki işlevleri çözümlenmiştir. Sonuç olarak Yakup Kadri’nin Sodom ve Gomore romanında çeşitli metinleri birbirinden farklı yöntemlerle kullandığı ve bunları bir tür “kültürel dönüş-türümün” ardından “yeniden yazdığı” ortaya konulmuştur. Üstelik bu durumun onun üslubunun önemli özelliklerinden biri olduğu gözler önüne serilmiştir. Son olarak yazarın bu çalışmada incelenenler dışında hangi metinlere gönderme yapıldığına değinilmiş ve sonraki çalışmalar için bir yol haritası oluşturulmuştur.This study is about investigation of Yakup Kadri Karaosmanoğlu’s novel Sodom ve Gomore (Sodom and Gomorrah) in terms of intertextual relationships. The novel leads the reader toward other texts, by starting from its name, and traces of this situation can be followed at a lot of layers of the novel, from roman characters to storyline (plot), fictionalization of time and space elements. In line with this, we, on the one hand, aimed to detect the author’s intertextual references, and to reveal usage modes of these references, on the other hand. Thus, we thought that at least one of constituents of his authorship would be enlightened. When the novel was approached from this perspective, it was seen that a lot of texts belonging to West-ern literatures, including narrations from Greek mythology, except for The Holy Scripture, were used in the structure of the novel through different intertextual methods. Accordingly, we detected that the most explicit texts that have a role at background layers were, together with mythological narrations, a lot of plays, in-cluding Picture of Dorian Gray by Oscar Wilde, Faust by Goethe and Antony and Cle-opatra by William Shakespeare, and we analyzed their functions in the structure of the novel. As a result of, we revealed that Yakup Kadri had used various texts through methods different from each other in the novel Sodom and Gomorrah, and that he “rewrote” those after a type of “cultural transformation”. Furthermore, we laid bare that this situation was one of important characteristics of his style. Finally, we addressed to which texts the author made a reference, except for those which were examined and constituted a road map for further studies
Die Geschichte vom weisen Qan Ögedei
No full textBensen üliger, Heftgeschichten, sind von ursprünglich schriftlicher Vorlage ausgehende mündlich tradierte moderne Spielmannsdichtungen der Inneren Mongolei. Bei den schriftlichen Vorlagen handelt es sich überwiegend um chinesische Romane oder Heldengeschichten, für die zum Teil auch mongolische Übersetzungen vorliegen. Bensen üliger werden bis heute von Spielleuten (mong.: quγurči) erzählt, die aus der Ost- und Südostmongolei stammen. Das hier zu untersuchende bensen üliger Ögedei mergen qaγan-u üliger („Die Geschichte vom weisen Qaγan Ögedei“) stammt aus einer Sammlung von Tonbandtranskripten mongolischer volksliterarischer Texte aus dem Nachlass von Prof. Dr. Walther Heissig. Diese Materialien hat Prof. Heissig der Nordrhein-Westfälischen Akademie der Wissenschaften und Künste in Düsseldorf vermacht. Ein großer Teil dieser Textsammlung ist bisher noch nicht bearbeitet bzw. noch nicht übersetzt worden. Die Handlung dieser Heftgeschichte spielt in der Yuán-Zeit und wurde im Herbst 1980 aufgenommen, die Aufnahmezeit betrug etwa 60 Stunden. Das vorliegende Werk enthält die uiguro-mongolische Transkription des bensen üligers Ögedei mergen qaγan-u üliger nach dem System von Poppe (2006). Der formale Aufbau der Transkription entspricht der handschriftlichen Vorlage. In der Heftgeschichte Ögedei mergen qaγan-u üliger sind der Autorin spezifische Sprachkontaktphänomene aufgefallen, die für das vorliegende Werk von besonderer Bedeutung sind. Es zeigt sich, dass die zweisprachig aufgewachsenen Mongolen in der Inneren Mongolei je nach Region in unterschiedlicher Stärke Chinesisch und Mongolisch abwechselnd oder miteinander vermischt verwenden. Im Fall der Vermischung wird das Chinesische dabei maßgeblich verändert. Diglossie und Bilingualismus führen zum Sprachwechsel (Codeswitching) und damit verbunden zu verschiedenen linguistischen Transfererscheinungen. Diese lassen sich in den Bereichen der Lexik, Phonetik und Morphologie nachweisen. Da es sich bei den bensen üliger um mündlich tradierte moderne Spielmannsdichtung handelt, treten verschiedene umgangssprachliche Elemente auf, beispielsweise eine große Anzahl an Sinismen (die mongolische Wiedergabe chinesischer Wörter und Begriffe). Die in diesem Band enthaltenen Sinismen sind sowohl ein Beleg für bestimmte Sprachkontaktphänomene in der Inneren Mongolei als auch dafür, dass diese ihren Eingang in das Repertoire der mongolischen mündlichen Tradition gefunden haben.Bensen üliger (booklet stories) are a literary genre representing the orally passed on modern Spielmannsdichtung of Inner Mongolia originally emanating from written templates. The latter are mostly Chinese novels or heroic stories for which a Mongolian translation exists in most cases. Bensen üliger are told by minstrels (Mong.: quγurči) from eastern and southeastern Mongolia until today. The bensen üliger Ögedei mergen qaγan-u üliger (“The story of wise Qaγan Ögedei”) under research is part of a collection of tape transcripts of Mongolian folk literature texts from the estate of Prof. Dr. Walther Heissig, who bequeathed these transcripts to the Nordrhein-Westfälische Akademie der Wissenschaften und Künste at Düsseldorf. A large part of this text collection has not yet been edited or translated. The story line of the present booklet story takes place during the time of Yuán dynasty and was recorded in autumn of 1980 with a recording time of about 60 hours. This book contains the Uiguro-Mongolian transcription of the bensen üliger Ögedei mergen qaγan-u üliger after Poppe’s (2006) system. The formal setup of the transcription is equivalent to the handwritten template. In the booklet story Ögedei mergen qaγan-u üliger, the author noticed specific phenomena of language contact which are of particular importance for the present study. It turned out that the Mongols from Inner Mongolia who grew up bilingually, depending on the region, use Chinese and Mongolian alternately or in mixed form. In the latter, they modify the Chinese language significantly. The use of language in specific functions (diglossia) in Inner Mongolia and the bilingualism (Mongolian, Chinese) of the Mongols leads to code-switching and, linked to that, to various linguistic transfer phenomena. These are measurable in the areas of the lexicon, phonetics, and morphology. Due to the fact that the bensen üliger are orally passed on modern Spielmannsdichtung, they contain elements of vernacular, like sinisms (the Mongolian reproduction of Chinese words and concepts). So the sinisms of this volume are evidence for the phenomena of language contact in Inner Mongolia and for the fact that these have found their way into the repertory of Mongolian oral tradition
Access to Information on the Fish Fauna from Lake Albert and its Tributary the River Semuliki (DR Congo)
No full textLake Albert, situated between Uganda and the Democratic Republic of Congo, is fed by the delta of a large river, Semuliki. It is considered one of the richest fishing lakes in the world. In 2013, 41 species of fish were identified in the lake and 15 in the delta. The author has digitized this information, including spatial distributions, ecological functions and economical value. These waterbodies are subject to multiple challenges, including uncontrolled over-exploitation of the resources ignoring compliance with any legislation, and lack of scientific studies due to insufficient means and supervision by the services in charge. The interest of multinational companies for oil exploitation is worrisome. Additionally, the results of research conducted on the Congolese side are not sufficiently digitized in their present state, not to mention a lack of planning for a rational use of the lake and the absence of a proper taxonomic identification key for this ichthyological area. The studies available on Fishbase are of great importance, but according to our analysis, they are not sufficient. Further research is necessary to update online repositories like Fishbase and others with more information about the ichthyofauna of the region. In addition to the fish, other animal and plant species of the region are also in need of inventories and studies. They are part of the richness of Lake Albert in need of protection from extinction before they even get identified. We are convinced that the application of TDWG standards and tools is critical to help strengthen our ability to do better research and enhance our current databases to make them openly accessible. This will also allow us to properly train and supervise the scientific research group, "Actions for the Protection and the Future of Lake Albert," which we have implemented to reach both the researcher and the local population to raise public awareness about the importance of the lake and its tributary. We envisage applying TDWG standards to a citizen sciences approach, adapted to the local context in DR Congo. Putting such a platform into place will not only be helpful for the researchers, but also enable local fishermen (professionals and amateurs) to fill in information about their catches and observations, including uploading of pictures using their smart phones in areas where Internet connections are unavailable
