Uso de pré-dicas informacionais em tarefas de alcance a um alvo: um estudo desenvolvimental

Alterações nas competências motoras da infância até a idade adulta envolvem vários aspectos do comportamento humano. Na perspectiva cognitiva, indivíduos planejam ações motoras através de três estágios seqüenciais e interdependentes: identificação do estímulo, seleção da resposta e programação da resposta. Após tais estágios que correspondem à preparação motora, o tempo de execução inicia. A partir do sinal imperativo, o executante seleciona e programa a ação. Se o estímulo é apresentado consistentemente da mesma forma, então a resposta a tal estímulo será mais rápida, comparada a uma situação em que o estímulo é apresentado de forma diferente do esperado. Neste último caso, o executante necessitará reprogramar sua ação motora e consequentemente levará mais tempo para planejá-la. O objetivo deste estudo foi examinar o efeito de informação prévia (i.e., dica) na preparação e execução de tarefa de alcance a um alvo por crianças de 6, 8, e 10 anos e adultos. Informação prévia era fornecida em três condições experimentais: correta, incorreta e neutra. As variáveis dependentes foram: tempo de reação (TR), tempo de movimento (TM), tempo de desaceleração (TD), índice de retidão (IR) e número de unidades de movimento (UnM). Com respeito à preparação da ação motora, os resultados indicaram que o TR diminuiu com a idade. Para as crianças de 6 anos, o TR com dica correta foi ligeiramente mais rápido do que na condição sem dica. Todavia, na condição com dica incorreta, o TR para as crianças de 6 anos era mais lento comparado com os demais grupos. Com respeito à execução da ação motora, os resultados indicaram mudanças desenvolvimentais em todas as variáveis dependentes, TM, TD, IR, UnM. De modo geral, os resultados do presente estudo mostraram que aos 6 anos de idade crianças são capazes de utilizar informação antecipada para preparar uma simples ação de alcance...

Atividades exploratório-investigativas em sala de aula de cálculo I com uso de tecnologia

This study presents the results from a qualitative resource, based on research-action methodology, which examined the innovate teaching practices implementations in the Calculus I during 2011 year. The analysis of collected data from three used sources – an initial questionnaire, an exploratory-investigative classroom, and an interview with some students at the end of the second semester – reveals that the students had appropriated of the technological recourses, using it as a tool to look for the knowledge. The investigative activities with the use of information technologies made the use of multiple representations in solving mathematical tasks, making the transition of numerical, algebraic and geometrical results possible for the students when they have looking for validation of their hypotheses and conjectures during mathematical problems solving. This works helped in the insertion of new practices in the discipline, and their results validate the proposal presented by the teacher, which is the discipline of Calculus use, whose character is strongly linked to the training content of the student, as a discipline whose can contributed to the pedagogical formation of the graduation student, leading him to know the Mathematical Education possibilities, specially the Mathematical Investigation - Solving Problems, in the outlook of dialogued classes where the teacher assumes the facilitator role and where the students become actives in their pursuit of knowledge

Uso do método de Monte Carlo para simulação e detecção do espectro de raios-X gerado com feixes de elétrons em alvo de Molibdênio, utilizando o Geant4

The huge demand for procedures involving ionizing radiation promotes the need for safe methods of experimentation considering the danger of their biological e ects with consequent risk to humans. Brazilian's legislation prohibits experiments involving this type of radiation in humans through Decree 453 of Ministry of Health with determines that such procedures comply with the principles of justi cation, optimization and dose limitation. In this line, concurrently with the advancement of available computer processing power, computing simulations have become relevant in those situations where experimental procedures are too cost or impractical. The Monte Carlo method, created along the Manhattan Project duringWorldWar II, is a powerful strategy to simulations in computational physics. In medical physics, this technique has been extensively used with applications in diagnostics and cancer treatment. The objective of this work is to simulate the production and detection of X-rays for the energy range of diagnostic radiology, for molybdenum target, using the Geant4 toolkit. X-ray tubes with this kind of target material are used in diagnostic radiology, speci cally in mammography, one of the most used techniques for screening of breast cancer in women. During the simulations, we used di erent models for bremsstrahlung available in physical models for low energy, in situations already covered by the literature in earlier versions of Geant4. Our results show that although the physical situations seems qualitatively adequate, quantitative comparisons to available analytical data shows aws in the code of Geant4 Low Energy source

Doping no esporte: uso de eritropoietina, propriedades, efeitos e detecção

A eritropoietina (EPO) é uma das drogas de uso proibido a atletas, segundo a lista anual da WADA. Este hormônio é uma proteína glicosilada com o potencial de estimular a eritropoiese, aumentando assim a quantidade de glóbulos vermelhos sanguíneos e indiretamente aumentando a capacidade de transporte de oxigênio aos tecidos. Os atletas, com este transporte incrementado, são beneficiados em esportes que exigem resistência física, tendo grande vantagem se comparados a atletas que não fizeram uso de eritropoietina...

Análise da dinâmica do uso da terra e sua interferência em enchentes na área urbana do município de Americana (SP)

Due to an intense process of population growth and urban density in Americana (SP), mainly due to the development of the local textile industry after 1970, there was, concomitant to the occupation of the margin of rivers and streams, soil sealing that increased the level of superficial runoff, triggering frequent floods. Based on the analysis of these processes we investigate the conditions of one densely urbanized area of the county, the Córrego do Parque, in three time series, 1977, 1996 and 2008. Taking as the starting the characterization and spatial distribution of landscape physiography, we prepared thematic letters and synthetic maps digital scale 1:10,000 from photointerpretation of aeroframes. The thematic maps were produced by scanning with subsequent edition using the software Auto-Cad Map. Checking the data and of geographic coordinates with GPS (Global Positioning System). Regarding land use classes, we used the description of the Soil Conservation Service (1975) which allowed us to get the Curve Number parameter, which will be used in hydrologic modeling for verification of flooding (Tucci, 1989). For the process of hydrologic modeling, we used models based on Methodology Object Oriented Modeling Applied to Water Resource Systems, Viegas Filho (1999), using the computer program called IPHS1, which uses models of the Soil Conservation Service (SCS , 2004), for conversion of rainfall-runoff and the spread of excessive rain. The results indicate that increased waterproofing generated by the change in use and occupation over the past decades promoted the increased surface runoff and drainage system overload, increasing the intensity of floods
