The aim of this study was to propose a reading of theoretical and methodological geography of Brazilian agriculture in Post-Graduate Studies in Geography (PPGE's) from the Southeast, from the 1970s, trying to present a discussion of the analysis categories (space, territory, landscape, region and place) that has been unleashed over the meetings of Agrarian Geography (ENGA's) and in three meetings of the Research Groups of Agrarian Geography (2005, 2006, 2007). So, we started with the hypothesis that the relativization of scientific concepts may impair development of spatial concepts only. To accomplish our objective we carried out a survey of dissertations and theses supported in the period 1970 to 2009, in Post-Graduate in Geography and UFU UFMG (Minas Gerais), UFRJ, UFF and UERJ (Rio de Janeiro) and USP, UNESP / Rio Claro, UNESP / Presidente Prudente (Sao Paulo). The evaluation dealt with the quantitative and drew a profile of Agrarian Geography. Qualitatively, further analysis, crossing information, contextualizing the themes and especially evaluating the theoretical set referenced in the works, an indication of the possible paths followed by this branch of the Brazilian Geography for which it is observed that the references to the categories space and, more specifically the organization of space, was prioritized in the 1980s and the territory as a reference work after 1990.

This paper examines how the reinvigoration of the exceptional American historical experience appears as a solution to some of the leading neoconservatives, considering Nathan Glazer and Irving Kristol as emblematic, regarding the fall of the American empire, beginning in the 1960s and 1970s, after its rise during the Cold War, the so-called 25 glorious years. We note that the arguments of these authors is rooted in the revival of reactionary rhetoric as an antidote to the decadence of American virtue supposedly caused by Communism, by the counterculture movement and the alleged perverse effect of the welfare state.

The work has for theme to understand the implementation of educational reforms in the decade of 1970 in the city of Bauru, because the city is a hub of academic reference of the central region of the State of São Paulo in Brazil. In this way, the work is committed to investigate the process of reorganization of basic and higher education system, as well as analyze their reflections on education in this region. He was subsidized by bibliographical and documental sources, using semi-structured interviews of a qualitative character

Linear resonant harvesters have been the most common type of generators used to scavenge energy from mechanical vibrations. When subject to harmonic excitation, good performance is achieved once the device is tuned so that its natural frequency coincides with the excitation frequency. In such a situation, the average power harvested in a cycle is proportional to the cube of the excitation frequency and inversely proportional to the suspension damping, which is sought to be very low. However, a very low damping involves a relatively long transient in the system response, where the classical formulation adopted for steady-state regimes do not hold. This paper presents an investigation into the design of a linear resonant harvester to scavenge energy from time-limited harmonic excitations involving a transient response, which could be more likely in some practical situations. An application is presented considering train-induced vibrations.

The linearity assumption in the structural dynamics analysis is a severe practical limitation. Further, in the investigation of mechanisms presented in fighter aircrafts, as for instance aeroelastic nonlinearity, friction or gaps in wing-load-payload mounting interfaces, is mandatory to use a nonlinear analysis technique. Among different approaches that can be used to this matter, the Volterra theory is an interesting strategy, since it is a generalization of the linear convolution. It represents the response of a nonlinear system as a sum of linear and nonlinear components. Thus, this paper aims to use the discrete-time version of Volterra series expanded with Kautz filters to characterize the nonlinear dynamics of a F-16 aircraft. To illustrate the approach, it is identified and characterized a non-parametric model using the data obtained during a ground vibration test performed in a F-16 wing-to-payload mounting interfaces. Several amplitude inputs applied in two shakers are used to show softening nonlinearities presented in the acceleration data. The results obtained in the analysis have shown the capability of the Volterra series to give some insight about the nonlinear dynamics of the F-16 mounting interfaces. The biggest advantage of this approach is to separate the linear and nonlinear contributions through the multiple convolutions through the Volterra kernels.

This text is about the appearing of Tourism graduation courses in Brazilian colleges. To this, the creation of the curricula at the Federal Board of Education was studied and the emergence of Tourism graduation courses offered by private universities. The creation of the first Tourism course in a public university â at the beginning of the 70âs at the School of Communications and Art of São Paulo University â is emphasized.

[ES] Pretendemos realizar el inventario y la catalogación de los fondos fotográficos de la Institución Ferial de Canarias (INFECAR), mediante el uso de las nuevas tecnologías informáticas, la digitalización de los originales y su descripción detallada en áreas y campos, dentro de bases de datos especializadas. Para posteriormente, con ese nuevo archivo creado, estudiaremos y analizaremos en sus diferentes vertientes, la importancia de la imagen (fotografías, obras de arte, arquitectura...) como elemento vertebrador de la propia historia de la Institución Ferial (imagen corporativa), que tiene su lógica plasmación en la sociedad canaria que la ampara.
