In this work, a tabu search algorithm for solving uncapacitated location problems is presented. The uncapacitated location problem is a classic problem of localization and occurs in many practical situations. The problem consists in determining in a network, at the minimum possible cost, the better localization, in a network, for the installation of facilities in order to attend the customers' associated demands, at the minimum possible cost. One admits that there exists a cost associated with the opening of a facility and a cost of attendance of each customer by any open facilities. In the particular case of the uncapacitated location problem there is no capacity limitation to attend the customers’ demands. There are some parameters in the algorithm that influence the solution’s quality. These parameters were tested and optimal values for them were obtained. The results show that the proposed algorithm is able to find the optimal solution for all small tested problems keeping the compromise between solution’s quality and computational time. However, to solve bigger problems, the structure of the algorithm must be changed in its structure. The implemented algorithm is integrated to a computational platform for solution of logistic problems

In this work we investigate the dissociation of heteronuclear diatomic molecules subjected to laser pulses. This phenomenon can be modeled by the classical forced Morse oscillator. This system presents a chaotic dynamics associated with the anharmonicity of the internuclear potential and with the coupling of permanent dipole of molecule with the electric field of laser. We want to verify how the dissociation probability evolves while we change the intensity and frequency of laser. We study the phase space of molecules to have a better understanding of system dynamics. We make the calculations changing two parameters of laser (intensity and frequency) and checking how this parameters influences on molecule dissociation. We compare the results of HF molecule (Fluoride acid) and CO molecule (Carbon monoxide) to check how the dipole moment of each molecule can influence on laser interaction

Initially, the text handles the theories of ancient classical and changes with the emerging of the debates of the schools of economic of Keynes and Kalecki. Over the years, from 1930 onwards, investment theories were debated and modified by various schools of economic thought. One of the debates that stands out in this work are the theories of Minsky that will bring new reformulations to Keynesian theory and a greater focus on psychological factors as determinants of investment decisions. Through financial instability hypothesis Minsky explains how the decisions to invest and the access to credit cause instability to financial system. Finally the work will show how access to credit is material when companies decide to invest and how these investments are often handled due to information asymmetries in the market. The financial institutions seek to maximize their profits while dribbling moral hazard and adverse selection, and thus the government needs to intervene once in a while as a regulator to maintain the solvency of the system

This final assignment aimed to promote a critical analysis of methods of preparation mappings danger of landslide and presentation of proposed development from the use of participative method, as an instrument to facilitate the identification of adverse geological processes. There search was executed from literature review about concept associated with geological dangers theme and the typology and characteristics of gravitational mass movements. We analyzed particularly the so-called methods of mapping danger tradicional/classic and alternative. It is believed, that integrating the work of specialists with the participation of involvedagents (local community and stake holders). This literature review and proposed work do noted in itself. You need the continuing advance in the discussion, debates and research on this topic as well as public policies that act on problems identified more concretely

In this work, the dissociation dynamics of heteronuclear diatomic molecules is investigated by means of the classical driven Morse oscillator. The interaction of the molecule and the laser field is represented through the product of the molecule dipole function and the electric field of the laser. This interaction may lead to the breaking of the chemical bound, that is, to the dissociation of the molecule. The work was developed in two parts. In the first part, we studied the dissociation as a function of the range of the permanent dipole. In the second part, we maximized the dissociation probability manipulating the parameters of the external field. We have observed that the dissociation can be controlled by means of variations of parameters associated with the range of the permanent dipole

This article has as objective to discuss some topics concerning the supposed crisis of the society of the work and its consequences for the debate in social sciences and also for the work category contextualization in the secondary school curriculum. As the work has represented an important explanation category for the classic social thought, the contemporary paradigm of deep metamorphoses in the world of the work and the advent of the new question (CASTELS, 1995; ROSANVALLON, 1995) backward the necessity to rethink the theoretical shades that base the interpretation of the social life on the current context, when the center position of the work is being questioned. Having taken some theoretical references from the sociology of the work, we search to delineate on a brief way the quarrel about the dimensions of the social and political phenomena these days and the importance of this debate on the contextualization of the secondary school curriculum contents.

Para que a inserção de conteúdos de Física Moderna e Contemporânea ocorra de maneira eficiente no ensino médio é necessária a atualização dos professores. Assim, desde 2010 a SBF realiza a Escola de Física CERN, na qual participam professores brasileiros de física. Perante isso, investigamos as contribuições desta escola para a prática pedagógica dos professores. Os resultados mostram que o ensino de partículas é realizado de maneira muito incipiente, justificado pelo fato do currículo ainda ser clássico, pela falta de tempo ou pela cobrança dos exames avaliativos. Ao mesmo tempo em que os professores mencionam abordar a física de partículas, eles relatam que assuntos de física moderna e contemporânea não fazem parte do currículo de suas escolas. Concluímos que alguns professores não ensinam a física de partículas ou o abordam mesmo que ele não faça parte da grade curricular.

Athletics in most of its history, turned to competition, giving it little pedagogical knowledge, prevailing knowledge grounded in records, indexes and competitions. Thus, although it is considered a classic content of Physical Education, this modality is still not widespread in schools. The present study aimed to investigate possible progress in the teaching and learning of athletics in the State Schools of Bauru from the implementation of the Curriculum of the State of São Paulo for Teaching Physical Education. We attempted to checking the perspective of teachers and students, the changes in teaching and learning as well as difficulties encountered from the deployment. To that end, we conducted survey of the theoretical and practical alternatives developed by Physical Education teachers, about athletics theme, since the implementation of the Curriculum of the State of São Paulo for the Teaching of Physical Education in 2008, in seven (7) state schools in Bauru-Sao Paulo, randomly chosen, prioritizing different regions of the county. There was the purpose of investigating, through questionnaires, interviews (applied to teachers and students), what progress has been achieved with regard to the approach of collegiate athletics in the teaching/learning process, if there are difficulties, what are these and how they could be addressed in order to improve teaching and learning in school athletics. The collected data were analyzed comparatively, before and after implementation of the Curriculum of the State of São Paulo for Physical Education, gathering and specifying negative and/or positive aspects raised by teachers and students. It was concluded that the students' knowledge of the sport has increased, but the practice of sport is still far from being normal to them, doing so is necessary to include content from the earliest school years. Teachers attribute the greatest difficulties to lack of infrastructure and materials suitable for this...

This work will address the study of fatigue conditions with constant load in an alloy of aluminum analysis 7475 - T761, so we can better understand the conditions of the aircrafts which contain this alloy in their structures. A literature review, which was discussed the concepts of fracture mechanics, fatigue, aeronautical components, chemical analysis of aluminum alloys, fatigue problems that appears in the aircrafts, metallographic analysis, and testing of optical microscopy tensile, fatigue and microhardness, surface analysis (MEV) study of the chemical composition of the alloy in question, the main causes of crashes, was performed, completing the work, analysis of data from tensile test, hardness and fatigue together with the interpretation of images of optical microscopy and scanning electron was taken. The data indicated the high mechanical strength of the alloy, along with its microstructure indicating elongated grains and high surface contour, which shows such resistance by hindering the movement of dislocations. The grooves are clearly shown in the MEV images as well as the classic with increased fatigue loading and subsequent reduction of the number of cycles to rupture behavior shown in the graphs. Therefore we observed the optimal behavior is supported by the league when subjected to fatigue loadings
