Possibilidades de exploração da história da ciência na formação do professor de matemática: mobilizando saberes a partir da obra de Nicolau Copérnico de revolutionibus orbium coelestium

This study aims to analyze the implications that the knowledge of an important work for the History of Science, De revolutionibus orbium coelestium , by Nicholas Copernicus, can bring for the formation of Mathematics professors. The study focuses on Book I of Copernicus s work, where, in the final part, is found the Table of the Subtense Straight Lines in a Circle, a true sine table constructed by the author. The study considers two theoretical references, the History of Science and of Mathematics, in the professor s formation searched amongst others in Miguel and Miorm, Brito, Neves and Martins, and Radford, and the necessary teaching knowledge professors mst have, on the basis of Gauthier, Schulman and Imbernón amongst others, through which it is established a net of knowledge grouped in dimensions such as mathematical, psycho pedagogical, cultural and practical diversity, that guide the study analysis. In the search for more necessary elements to enrich the analysis, beyond the theoretical research in Book I, it is carried through, with under graduation pupils, future Math professors, the construction of a sine table following the project used in De revolutionibus . The study still makes a description of the life and work of Nicholas Copernicus, detaching the historical context where the author lived and the conceptions about the Universe existing at that time. The research reveals that the studied work is an important source of culture, able to provide to the Mathematics professor in formation, beyond the conceptual and procedural mathematical knowledge, a cultural knowledge that allows him to be opened to the knowledge of other areas that not his specific area, and so to acquire knowledge about the world history, the development of sciences and of the society

Influence of alternative electron acceptors on the anaerobic biodegradation of polycyclic aromatic hydrocarbons

Polycyclic aromatic hydrocarbons are chemicals produced by both human activities and natural sources and they have been present in the biosphere since millions of years. For this reason microorganisms should have developed, during the world history, the capacity of metabolized them under different electron acceptors and redox conditions. The deep understanding of these natural attenuation processes and of microbial degradation pathways has a main importance in the cleanup of contaminated areas. Anaerobic degradation of aromatic hydrocarbons is often presumed to be slow and of a minor ecological significance compared with the aerobic processes; however anaerobic bioremediation may play a key role in the transformation of organic pollutants when oxygen demand exceeds supply in natural environments. Under such conditions, anoxic and anaerobic degradation mediated by denitrifying or sulphate-reducing bacteria can become a key pathway for the contaminated lands clean up. Actually not much is known about anaerobic bioremediation processes. Anaerobic biodegrading techniques may be really interesting for the future, because they give the possibility of treating contaminated soil directly in their natural status, decreasing the costs concerning the oxygen supply, which usually are the highest ones, and about soil excavations and transports in appropriate sites for a further disposal. The aim of this dissertation work is to characterize the conditions favouring the anaerobic degradation of polycyclic aromatic hydrocarbons. Special focus will be given to the assessment of the various AEA efficiency, the characterization of degradation performance and rates under different redox conditions as well as toxicity monitoring. A comparison with aerobic and anaerobic degradation concerning the same contaminated material is also made to estimate the different biodegradation times.

Globalized Antiquity: Uses and Perceptions of the Past in South Asia, Mesoamerica, and Europe

„Antike“ ist keine europäische Exklusivität: Das Buch zeigt, wie in Südasien, Mesoamerika und Europa je eigene Antiken konstruiert werden. In den untersuchten vorkolonialen, kolonialen und postkolonialen Zusammenhängen wird die Antike durch die zeitgenössische Geschichtspolitik stark mitbestimmt. Der Vergleich lässt die Verflechtung der Vorstellungen über die Vergangenheit zwischen „klassischer“ europäischer, indischer und mesoamerikanischer Antike von der frühen Neuzeit bis in die Gegenwart erkennen. Das Buch bietet Denkanstöße für Personen, die sich mit historisch interessierter Kulturanthropologie, kritischer Altertumswissenschaft und Globalgeschichte beschäftigen.

Periodising globalisation: Mauritian integration into the sugar commodity chain (1825-2005)

Using the case study of Mauritius, and its integration into the international sugar commodity chain, this paper shows that the analysis of commodity chains can be fruitfully employed to respond to recent calls in the field of global/world history for a periodisation of globalisation. The entry of Mauritius into the British Empire brought about a particular kind of integration of the island into the capitalist world system. Central to this integration was the production of sugar under the West Indian Sugar Protocol, with this ultimately turning Mauritius from a free port into a plantation economy. This shaped the island's economic and political practice, and brought the formation of a range of institutions that sustained a high degree of inequality among Mauritians by finding ever newer ways of conciliating socio-economic mobility with exploitation. The paper discusses Mauritian history through the framework of bilateral and multilateral trading agreements that had a significant impact on the sugar industry, and kept the island economically dependent on this single crop. This only changed when the postcolonial state succeeded in diversifying the Mauritian economy during the 1970s and 1980s.

Ciudadanía femenina en El Salvador : Prudencia Ayala

El relato de la historia mundial, y de la historia de América Latina, ha sido escrito mayoritaria- mente por hombres. Por esa razón, este trabajo da cuenta de la participación y contribución del género masculino, con la excepción de contadas mujeres en el Salvador. Si bien es cierto que muchos campos estuvieron vedados a las mujeres por siglos, éstas no cesaron de defender la igualdad de derechos, constituyéndose en verdaderas protagonistas de nuestra historia en el campo de la política y la ciudadanía femenina. Por ello centramos el foco en el proceso de lucha de las mujeres salvadoreñas para ejercer este derecho, a través de la figura Prudencia Ayala, una mujer indígena y pobre, candidata a la presidencia en 1930.

Conciencia histórica : Pasado y presente en la perspectiva de los jóvenes en Portugal

La investigación en educación histórica, de naturaleza esencialmente cualitativa en la línea de los trabajos pioneros de Peter Lee y Denis Shemilt en el Reino Unido, ha sido especialmente fructífera para una enseñanza de calidad. Actualmente, uno de sus enfoques más relevantes ha sido la prospección de indicadores de conciencia histórica de los jóvenes, en la perspectiva del filósofo Jörn Rüsen. Dentro de este marco teórico, se desarrolló un estudio con alumnos portugueses del 9° año de escolaridad con el fin de explorar, a través de las narrativas que construyen sobre la Historia del país y del mundo contemporáneo, las relaciones implícitas entre comprensión del pasado y formación de identidades a nivel nacional y global, en conexión con las concepciones acerca de cambio histórico y orientación temporal. Los resultados que se presentan son discutidos como diagnóstico de la construcción de la conciencia histórica de los jóvenes, constituyéndose como una base de reflexión para prácticas consistentes en el área de Enseñanza de la Historia
