José Alves de Freitas Neto
História da Historiografia , 2011,
Abstract: O artigo analisa o trabalho histórico de Bartolomé Mitre na Argentina da segunda metade do século XX. S o apresentadas as polêmicas em torno da escrita da história, o debate em torno do rigor erudito, a composi o do acervo documental e alguns temas enunciados em suasobras principais, a Historia de Belgrano y de la independencia argentina (1887) e a Historia de San Martin y de la emancipación sudamericana (1888). Nesse processo, busca-se abordar as rela esentre política e história, assim como elementos que justificam a presen a de Mitre no centro do debate historiográfico argentino, as contradi es e paradoxos que o historiador sinaliza, assim como sua condi o de patrim nio da cultura historiográfica platina.

Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.911121
Abstract: The flipped classroom is an active teaching methodology that alters the organization logic of face-to-face teaching, in which content is studied before students attend class, emphasizing the active participation of the student in the search of knowledge and teamwork during the resolution of tasks, giving opportunities to experience educational practices that allow the simultaneous execution between theory and practice. However, when using this methodology, a problem that occurs during its application is the difficulty for the teacher (facilitator) to follow the whole progress of the activities performed outside the classroom. Thus, this paper presents the development and evaluation process for a multi-agent system to support the flipped classroom according to the needs of users, with the purpose of correcting the problem inherent to the implementation of this learning theory.

Abstract: the purpose of this study was to analyze the influence of cold water immersion (cwi) following acute physical exercise on the oxidative stress in the blood plasma. twelve men with average age of 22±1 years old, participated this study. all of them underwent the treadmill stress test followed by cwi in tank with water at 10oc for 10 minutes. during this process, they were monitored and a set of parameters were analyzed: physical effort perception (borg scale), heart rate (hr), blood pressure (bp) and body heat, by measuring tympanic temperature. the morphological analysis of oxidative stress in blood plasma was done in accordance with a method known as optical morphology of the oxidative stress on blood plasma, which uses drops of capillary blood. a significant increase (p<0.01) in the rate of oxidative stress in plasma was noted after intense physical effort when compared with the rate of stress while at rest. however, the stress rate was significantly decreased (p<0.001) after cwi. although further scientific studies should be carried out on the above mentioned test, may be concluded that, in the present study, the test has proven itself viable. the data found in the present study suggest that cold water immersion at 10oc for 10 minutes following high intensity physical effort appears to be an important physical therapeutic measure towards the normalization of oxidative stress.

Abstract:

DNA replication is a crucial process for species survival, nevertheless it is not clear which factors define origin selection in multicellular eukaryotes. Developmental gene amplification systems, such as the one described during ovarian follicles development in Drosophila melanogaster, are useful tools for studying of DNA replication process in these organisms. We previously described that the well characterized third chromosome amplified domain of D. melanogater displays three intrinsically bent DNA sites: b1, localized at an amplification control element (ACE3), b2 and b3, both localized at the preferential origin ori-β. This proposal aimed to construct a Drosophila transformation vector, which contains a short deletion at the ACE3, in order to reduce the intrinsically bent DNA site b1, and analyze the functional role of this site in the gene amplification process. Through a series of cloning steps, we obtained a Big Parent vector derivative, containing a deletion at the positions 176-

Abstract: The Problem-Based Learning (PBL) is an active teaching methodology developed through self-directed study and group work, with the objective of problem solving. However, using this methodology, some challenges appear in its implementation, for example, the difficulty of monitoring conversations unrelated to the context of the proposed problem, distancing itself from the center of the discussion andcommitting the learning objectives. Another factor to be considered is the formation of groups, since the methodology does not establish criteria for how to select the teams so that they are distributed in a heterogeneous way. The supervision of accomplishmentof the PBL implementation cycle also requires from the facilitator frequent monitoring for the effectiveness of the methodology, representing a task that is difficult to verify, when it refers to the application of the individual or autonomous study. In this sense, this work presents a computational tool to support the PBL, which aims to contemplate the above-mentioned difficulties inherent to the implementation of this methodology and to assist in the teaching-learning process.
