The life expectancy increase has been augmenting studies on human aging. Among these studies are those that address the interaction between the elderly and the information and communication technologies, which may facilitate the execution of daily activities by elderly people. Therefore, the goal of this article was to investigate the application of constructivist elements in computer courses offered to Universidade Aberta à Terceira Idade – UNATI – UNESP – Campus of Marília, contributing to the digital inclusion of this community. The constructivist elements focused on the role of the teacher as a mediator in the teaching-learning process. It was found that most of these elements are already being applied in this universe, but some changes need to be undertaken in order to expand the opportunities for education and to allow students to have more autonomy for information seeking and use in the web environment.

This paper aims to understand the nature of personal archives and their main features based on the collector entity IEB-USP (Instituto de Estudos Brasileiros da Universidade de São Paulo). Based on this entity and on archival theory, we discuss here, differences and similarities between the organic and private archives realizing the intrinsic value established on personal archival and how its institutionalization is denominated, once it directly pervades the attribution of value that is assigned and settled, relating to the work and life of a political or artistic personality, and also related to the collective memory and legacy left for this historically, aesthetic and socially important figures. We highlight, here, the approximation of Archival Science and Information Science and Library through the principles and organization methodologies applied to personal archives.

This article aims to address the relationship between work and professional education, specifically the ideology skills and the new pedagogy business under the globalization of capital. Is analyzed at first, the world-historical context, the restructuring of the productive and political capital from the 1970s, and the demand for a new organization of work based on model Toyota. Second, discuss such changes are productive within the Brazilian state and its influence on educational policies geared to work, permeated by the ideology skills as an instrument that seeks to obscure the relationshipcapital. It discusses the emergence of new education business connected to the ideals of human capital. It is the influence of international organizations in Brazil of the United Nations (UN) and the United Nations Organization for Education, Science and Culture (UNESCO), aimed at articulating the education according to the ideological aspect global, verified legislative apparatus in education. Ends up not only to reflect the content of the skills ideology, but it is suggested the redemption value of the denied promise of emancipation human-general.

This experiment aim was to evaluate the contamination of the trace elements (TE) arsenic, barium, cadmium, chromium, copper, mercury, molybdenum, nickel, lead, selenium, and zinc considered in the CONAMA resolution 375 after 13 years long using sewage sludge (SS) as fertilizer in two soils: an Eutroferric Clayed Red Latosol (Rhodic Eutrudox - RE) and a Dystrophic Red Latosol (Typic Haplorthox - TH). Experiment in the field under maize cultivation had four treatments (0, 5, 10, and 20 t of SS ha(-1), dry weight), five replications and an experimental design in randomized blocks. The agrochemicals (dolomitic limestone, single superphosphate, and potassium chloride), SS, soils, and the certified reference materials were digested according to the USEPA 3051A method and the chemical elements were quantified by ICP OES. The TE contents found in the agrochemicals used should not cause immediate environmental impact. The higher TE values were found in the RE and they did not reach the agricultural (more stringent) Investigation Level (IL) yet, according to 420 CONAMA resolution. Persisting the actual SS fertilization amount applied in the soil and the TE concentration in the SS is foreseen that Ba, Cd, Cr, Cu, Ni, and Zn will be the first elements to reach the IL in the RE.

Through deductions and formulations of the equations governing the behavior of plates elastic and thin based Kirchhoff theory, it is evident that it is justifiable to the complication of the numerical methods considering the complexity of the equations that describe the physical behavior of these elements and obtaining analytical solutions for specific situations. This study is directed to the application of the numerical method which is based on discretizations to the simplest elements which results in the reduction of data to be processed from. The numerical method in question is the Boundary Element Methods (BEM), as the name suggests, the discretizations are only the edges of the elements. The BEM converts the complex integral equations, in sums of functions that reduce the unknowns at the nodes that define the ends of discrete elements, obtaining internal values to elements using interpolation functions. Confirming the need and usefulness of the BEM, apply, then the foundations necessary to the specific cases of Civil Engineering where traditional methods do not provide the desired support, leaving in question the security situations and economics of the projects

Um bloco de poliuretano recebeu três implantes de hexagono externo, no posicionamento compensado. Para cada implante foi conectado o pilar protético microunit. Foram realizados cinco enceramentos com três coifas plásticas cada um, que foram fundidos em monobloco numa liga de cobalto-cromo. Foram colados quatro extensomêtros tangenciando cada implante, sendo dois extensomêtros para o implante central. Após o acabamento, as estruturas foram fixadas nos respectivos locais com o parafuso de retenção com torque de 10 Ncm, obtidos com um torquímetro. Para aplicação de carga sobre os corpos-de-prova foram selecionados cinco pontos de aplicação de carga. O dispositivo de aplicação de carga–DAC foi utilizado 30 kg de cargas verticais estáticas, empregando uma ponta esférica de 2 mm de diamêtro, durante 10 segundos em cada um dos pontos estabelecidos, sendo, neste instante registradas as micro deformações de cada extensômetro. Foi utilizado o teste de análise de variância T Student e o nível de significância foi o valor convencional de 5%. Para cada implante foi analisada a microdeformação ocorrida. Os resultados obtidos mostraram que houve uma diferença estatisticamente significativa entre os pontos não-axiais D e E (t = 5,21 df = 4, p = 0,006 < 0,05) e não foi estatisticamente significativa para os dados axial entre os pontos B e C (t = 6, 57, df = 4, p = 0,003 < 0,05 / 3). Conclui-se que,a aplicação de carga ao redor de três implantes de hexágono externo no posicionamento compensado,mostra que os pontos não-axiais sofrem maior micro deformação do que os pontos axiais

Currently one of the great concerns of the aeronautical industry is in relation to the security and integrity of the aircraft and its equipments / components when under critical flight maneuvers such as during landing / takeoff and emergency maneuvers. The engineers, technicians and scientists are constantly developing new techniques and theories to reduce the design time and testing, ir order to minimize costs. More and more the Finite Element Method is used in the structural analysis of a project as well as theories based on experimental results. This work aimed to estimate the critical load to failure for tensile, compression and buckling of the Tie-Rod, a fixture aircraft widely used on commercial aircrafts. The analysis was performed by finite element method with the assistance of software and by analytical calculations. The results showed that the Finite Element Method provides relative accuracy and convenience in the calculations, indicating critical load values slightly lower than those found analytically for tension and compression. For buckling, the Finite Element Method indicates a critical load very similar to that found analytically following empirical theories, while Euler's theory results in a slightly higher value. The highest risk is to fail by buckling, but the geometric irregularity of Tie-Rod pieces makes difficult the calculations, therefore a practical test must be done before validation of the results

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
