The study of oscillatory phenomena is an important topic in several areas of knowledge. The understanding and the solution of many problems that scientists and engineers confront nowadays can be formulated, at least as an analogy, in terms of an oscillatory movement. The description of the motion of this nature has remarkable contributions to the mathematical and conceptual formation of the students and for solving daily problems in several areas. In this paper we propose a theoretical and experimental approach involving the phenomenon of harmonic oscillations in two dimensions. Lissajous curves were used as experimental demonstration of the resulting trajectories. These curves were obtained from relatively simple experimental apparatus, which is affordable in most teaching laboratories of physics.

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

Even today tables are used in the calculation of structures formed by flat elements, these methods are acceptable only for a limited number of cases, but even so, in some situations, tables are used. With time some methods of differential equations resolutions were emerging and accepted as the most effective solution. Today, with the advancement in technology, there are already some programs able to solve more complex problems in less time using these methods. Aiming to optimize time and better understand the physical behavior of plates, this work presents the theory of plate, the Boundary Element Method (BEM) applied to solve problems of plates (slabs) with various boundary conditions and load through the program Placas2 (TAGUTI, Y.-2010) in Fortran language

The problem of solid waste has caused discussions about the huge amount that is generated in Brazilian cities, in particular the waste from construction and demolition (CDW), called spoil. In many cases these wastes are disposed of improperly and even criminally in urban areas, causing serious economic, social and environmental problems. Due to the lack of public policies and appropriate management of such waste came up with the CONAMA, in its resolution nº 307 of 2002, the obligation of municipalities in deploy the integrated management of construction and demolition wastes for the resolution of problems caused by inadequate management and disposal of such waste. By following a methodology suggested by Pinto & González (2005), with adaptations of other authors, it is proposed in this work the lifting of a diagnosis of the CDW in the municipality of Guaratinguetá-SP, through theoretical analysis and field research, with purpose to guide the public servants in the elaboration and implementation of integrated management. The results must contain information necessary for that end, such as the knowledge of generators, agents, collectors and transporters, disposition areas and the disposal of waste

Sabendo-se da importância da mídia em informar e difundir a cultura, faz-se necessário uma análise de suas influências junto a seus receptores. Para tanto, o presente trabalho propôs verificar a maneira como a temática da violência escolar é abordada por três mídias impressas, escolhidas para a pesquisa. Foram investigadas três mídias de circulação nacional, com periodicidades semanais, quinzenais e mensais e com públicos-alvo direcionados ou não. Os alvos de reflexão para a pesquisa foram o tema violência escolar e o discurso da mídia sobre esse tema a fim de verificar sua possível contribuição para a resolução dos problemas relacionados à violência nas escolas. Também foi feita uma análise bibliográfica acerca do assunto pesquisado para fundamentar a análise dos dados coletados. Diante dos objetos estudados a pesquisa apresentou alguns dados indicativos positivos, porém observou-se que ainda é preciso avançar no conteúdo das questões e assuntos que abordam a violência escolar.

This work presents a study about the use of standards and directions on parallel programming in distributed systems, using the MPI standard and PETSc toolkit, performing an analysis of their performances over certain mathematic operations involving matrices. The concepts are used to develop applications to solve problems involving Principal Components Analysis (PCA), which are executed in a Beowulf cluster. The results are compared to the ones of an analogous application with sequencial execution, and then it is analized if there was any performance boost on the parallel application

In Brazil, The power generation has always depended on the rivers, in other words, there are moments that the power generation can vary, which can cause variations in energy supply and even blackout according to the level of water in the reservoirs of the hydroelectric plants. For this reason, many options has been studied, like our example, which is about a combined cycle power plant in Canas. The use of combined cycle is interesting from the point o view of energy, because its efficiency is between 50 and 60%, and from the point of view of environment, because it can burn natural gas, which is cleaner than coal, it reduces the emission of gases that influence on the greenhouse effect. This work aims to perform a technical analysis of a case study of a power plant proposed to be built in Canas by the AES/AES Tietê Group. For the analysis will be used the commercial software GateCycle 6.0.0 from GE, this software has the power of simulating power generation cycles (nuclear, combined, etc.). The energy department of UNESP has the license, which makes possible the academic use of this tool. Two combined cycles were simulated, one using one pressure level HRSG, and another one closer to the real power plant, which is a combined cycle with a three pressure level HRSG. The results were close to expected, for the combined cycle with one pressure HRSG the power was 513,9 MW and a efficiency of 53,27%, in the case with the three pressure level HRSG the power was 517,1 MW and a efficiency of 53,5%. We conclude that the software requires that the user must have the knowledge about the subjects involved in the use of GateCycle in problems resolutions

A matemática está presente nas mais diversas atividades do nosso cotidiano. O interesse em realizar o Trabalho de Conclusão de Curso no âmbito da Educação de Jovens e Adultos/EJA, surgiu a partir do meu ingresso no Programa Institucional de Bolsa de Iniciação à Docência - PIBID no início do ano de 2010. O PIBID vem sendo desenvolvido em vários campi da Unesp, somente nos cursos de licenciatura e tem como financiadora a CAPES/MEC. No curso de licenciatura Plena em Pedagogia, o Programa EJA/PIBID Rio Claro atua na escola Municipal Celeste Calil, localizada em um bairro periférico, que tem como público alvo pessoas de baixa renda, alfabetizadas ou não. O trabalho que a cada dia vem sendo construído com as educandas me despertou muito interesse, principalmente com relação ao ensino da matemática, uma vez que a mesma está presente nas diversas esferas do cotidiano. Podemos acompanhar (observar) que as alunas já trazem consigo uma experiência de vida muito grandiosa com relação à solução de questões pertinentes a matemática. Para auxiliar na aprendizagem, recursos matemáticos vêm sendo introduzidos nas aulas, entre eles jogos, onde as educandas podem reviver situações cotidianas que, à primeira vista, facilita o processo de aprendizagem e resolução de problemas. O presente trabalho tem como objetivos fazer um levantamento de jogos matemáticos que poderão ser utilizados nas aulas da EJA, e também analisar o caderno de registros matemáticos do PIBID, no ano de 2010. Quanto à metodologia, buscam-se elementos na pesquisa qualitativa, bem como análise bibliográfica de jogos que foram levantados e também análise documental do caderno de registros do PIBID 2010, construído conjuntamente, pelo grupo de educandas e bolsistaseducadores

The aim of the present study was to analyze the impact suffered by 40 people when discovering that one of their family members was diagnosed with cancer, to analyze their coping strategies and expectations towards the patient’s illness and future. The study made use of the Coping Strategies Inventory by Folkman and Lazarus. Results show that most of the patients’ caregivers are their married children, with an average age of 45.7 (dp=12.67), and gainfully employed. These family members reported the negative impact of the diagnosis, with the predominant feelings of sadness and fear of loss, even though they had a positive perspective about the future, expecting the patient’s recovery. As to the functional coping strategies, the most used were the resolution of problems, followed by social support; the least used was positive revaluation. As to the dysfunctional strategies, the most used ones were escape and avoidance and the least used was taking the responsibility for the illness. Conclusions are that despite suffering with the negative impact of the disease, the family members are optimistic about the patient’s future and seek to use strategies that solve the problem effectively, without blaming themselves for the patient’s illness.
