Corpo e saúde: reflexões sobre o quadro "Medida Certa"

The present scenario is permeated by different comprehensions about the body and health. These are the result of a historical process experienced by men in different times and social contexts through which were being built. Faced this scenario, we emphasize the media as a powerful means of information and training ideas regarding the body and health of theses. The media also as a means of mediating information we present characteristics of the social scenario where is inserted. In our research we bring reflects about the comprehensions, knowledge and practices propagated by the way the body and health under "Medida Certa" of the program Fantastico the broadcaster Globo Telecommunications, in order to identify how Physical Education, has contributed the construction of knowledge disseminated. Therefore, we focus our analysis to the table "Medida Certa" exhibited by Fantastico in the months of April, May and June of 2011.The data for analysis were collected through the videos shown live in Fantastic and the information provided in the blog that table. Thus, we had 14 videos shown live, 16 videos posted on the blog, 97 posts in blog. As technique of analysis of the datas used of content analysis of the Bardin (2011). About body obtained as analytical categories: body as operating system; biological body; fragmented body exterior to the subject; body trailer quantified to patterns; subject body. How to health we analyze the categories of health existential: health existential based in biological indices of normality; health existential associated with weight loss and aesthetic patterns; health existential associated with physical activity and nutritional control; and finally we propose a comprehension of health existential. Therefore, from the analysis of the data evidenced a predominance of comprehensions, knowledge and practices about the body and health guided the biological constituents of the body, quantification and classification in medium and normal patterns on pervasive forms of care, in the linear association among physical activity and nutritional control with health, evidenced that Physical Education has contributed to these constructions, through some of his discourses with emphasis on biological aspects. Thus, in our study we advocate an understanding of not only the body as object, but also as a subject clipped by organic, cultural, historical and social elements, a living body, feeling, desire and above all expresses itself, and health viewed as something body, interlaced through the biological, cultural, historical and emotional aspects of this body that coexist in this society

Avaliação do potencial do uso balanced scorecard: um estudo exploratório em Natal

Small businesses are experiencing growth scenario in emerging countries by the prospect of economic development, these countries, including Brazil, have a booming economy before the world crisis in the last five years, especially with the participation of small and medium enterprises. These factors generate increased competition and the need to expand market share through management actions in the quest for acquiring new customers. Moreover, these changes increase the need to properly use the information and organizational performance. Some national and international studies show the existence of peculiarities in small organizations, especially in environments of family management. Such particularities raise a scenario with several organizational deficiencies regarding the evaluation of their performance. In some cases, when there are static systems, traditional and focused only on the financial perspective, especially short term. Alternatively, the tools encourage strategic planning and observance of medium and long term, in many ways, whether financial, internal processes, customers, suppliers, and innovation, among others. Therefore, this study aims to identify and analyze the applicability of the system performance evaluation with emphasis on strategic and BSC - Balanced Scorecard. Regarding the research method, is classified as exploratory, with the participation of 25 companies, whose research was conducted between 2012 and 2013. Therefore, the research included the construction process and a structured questionnaire on practices and interest for the use of strategic tools, with emphasis on the Balanced Scorecard. Whose main result presented a high degree of interest in the applicability of the BSC by most of the participating institutions. Furthermore, It was observed the growing interest in using the Balanced Scorecard when it increases the company size, regardless of the area of market action. Participating companies have shown an outline of the strategic objectives and the establishment of indicators for assessing the performance due to their correlations with the BSC

Uma fonte chaveada de 50kW com correção de fator de potência para alimentação de uma tocha de plasma Indutiva utilizando técnicas de controle digital

This work deals with the development of an experimental study on a power supply of high frequency that provides the toch plasmica to be implemented in PLASPETRO project, which consists of two static converters developed by using Insulated Gate Bipolar Transistor (IGBT). The drivers used to control these keys are triggered by Digital Signal Processor (DSP) through optical fibers to reduce problems with electromagnetic interference (EMI). The first stage consists of a pre-regulator in the form of an AC to DC converter with three-phase boost power factor correction which is the main theme of this work, while the second is the source of high frequency itself. A series-resonant inverter consists of four (4) cell inverters operating in a frequency around 115 kHz each one in soft switching mode, alternating itself to supply the load (plasma torch) an alternating current with a frequency of 450 kHz. The first stage has the function of providing the series-resonant inverter a DC voltage, with the value controlled from the power supply provided by the electrical system of the utility, and correct the power factor of the system as a whole. This level of DC bus voltage at the output of the first stage will be used to control the power transferred by the inverter to the load, and it may vary from 550 VDC to a maximum of 800 VDC. To control the voltage level of DC bus driver used a proportional integral (PI) controller and to achieve the unity power factor it was used two other proportional integral currents controllers. Computational simulations were performed to assist in sizing and forecasting performance. All the control and communications needed to stage supervisory were implemented on a DSP

Efeitos do envelhecimento ambiental acelerado em compósitos poliméricos

The advantages of the use of vegetable fibers on the synthetic fibers, such as glass fibers, in the reinforcements in composites are: low cost, low density, good tenacity, good thermal properties and reduced use of instruments for their treatment or processing. However, problems related to poor performance of some mechanical natural fibers, have hindered its direct use in structural elements. In this sense, the emergence of alternative materials such as hybrids composites, involving natural and synthetic fibers, has been encouraged by seeking to improve the performance of structural composites based only on natural fibers. The differences between the physical, chemical and mechanical properties of these fibers, especially facing the adverse environmental conditions such as the presence of moisture and ultraviolet radiation, is also becoming a concern in the final response of these composites. This piece of research presents a comparative study of the strength and stiffness between two composite, both of ortoftalic polyester matrix, one reinforced with fibers of glass-E (CV) and other hybrid reinforced with natural fibers of curauá and fiberglass-E (CH). All the comparative study is based on the influence of exposure to UV rays and steam heated water in composites, simulating the aging environment. The conditions for the tests are accelerated through the use of the aging chamber. The composites will be evaluated through tests of uniaxial static mechanical traction and bending on three points. The composite of glass fiber and hybrid manufacturing industry are using the rolling manual (hand lay-up) and have been developed in the form of composites. All were designed to meet possible structural applications such as tanks and pipes. The reinforcements used in composites were in the forms of short fiber glass-E quilts (450g/m2 - 5cm) of continuous wires and fuses (whose title was of 0.9 dtex) for the curauá fibers. The results clearly show the influence of aging on the environmental mechanical performance of the composite CV and CH. The issues concerning the final characteristics of the fracture for all types of cargoes studied were also analyzed

Utilização de RNA´s na construção do diagrama de vida constante de probabilidade de materiais compósitos

The static and cyclic assays are common to test materials in structures.. For cycling assays to assess the fatigue behavior of the material and thereby obtain the S-N curves and these are used to construct the diagrams of living constant. However, these diagrams, when constructed with small amounts of S-N curves underestimate or overestimate the actual behavior of the composite, there is increasing need for more testing to obtain more accurate results. Therewith, , a way of reducing costs is the statistical analysis of the fatigue behavior. The aim of this research was evaluate the probabilistic fatigue behavior of composite materials. The research was conducted in three parts. The first part consists of associating the equation of probability Weilbull equations commonly used in modeling of composite materials S-N curve, namely the exponential equation and power law and their generalizations. The second part was used the results obtained by the equation which best represents the S-N curves of probability and trained a network to the modular 5% failure. In the third part, we carried out a comparative study of the results obtained using the nonlinear model by parts (PNL) with the results of a modular network architecture (MN) in the analysis of fatigue behavior. For this we used a database of ten materials obtained from the literature to assess the ability of generalization of the modular network as well as its robustness. From the results it was found that the power law of probability generalized probabilistic behavior better represents the fatigue and composites that although the generalization ability of the MN that was not robust training with 5% failure rate, but for values mean the MN showed more accurate results than the PNL model

Análise da eficiência de aquecedor solar espiral com e sem efeito estufa para piscinas

The technical and economic viability of solar heating for swimming pools is unquestionable, besides there it replaces the high costs and environmental impacts of conventional supply of energy, and it improves an optimization in the pool heating uses. This work applies the principles of the greenhouse effect: advanced thermodynamics, heat retention and equalization of temperature, to optimize the solar heating equipment, reducing the area required by collectors as much as 40% (still estimated value) for commercial collectors, with minor architectural and aesthetic impacts on the environment. It features a solar heating alternative in pools, whose main characteristics: low cost, simplicity in manufacturing and assembly and a faster heating. The system consists of two collectors spiral hoses made of polyethylene with a hundred meters each, and working on a forced flow, with only one pass of the working fluid inside the coils, and is used to pump itself treatment of pool water to obtain the desired flow. One of the collectors will be exposed to direct solar radiation, and the other will be covered by a glass slide and closed laterally, so providing the greenhouse effect. The equipment will be installed in parallel and simultaneously exposed to the sun in order to obtain comparative data on their effectiveness. Will be presented results of thermal tests for this the two cases, with and without transparent cover. Will be demonstrated, by comparison, the thermal, economic and material feasibility of these systems for heating swimming pools.

Modelagem dinâmica do escoamento de um sistema de elevação por plunger lift

A critical problem in mature gas wells is the liquid loading. As the reservoir pressure decreases, gas superficial velocities decreases and the drag exerted on the liquid phase may become insufficient to bring all the liquid to the surface. Liquid starts to drain downward, flooding the well and increasing the backpressure which decreases the gas superficial velocity and so on. A popular method to remedy this problem is the Plunger Lift. This method consists of dropping the "plunger"to the bottom of the tubing well with the main production valve closed. When the plunger reaches the well bottom the production valve is opened and the plunger carry the liquid to the surface. However, models presented in literature for predicting the behavior in plunger lift are simplistic, in many cases static (not considering the transient effects). Therefore work presents the development and validation of a numerical algorithm to solve one-dimensional compressible in gas wells using the Finite Volume Method and PRIME techniques for treating coupling of pressure and velocity fields. The code will be then used to develop a dynamic model for the plunger lift which includes the transient compressible flow within the well

Ensaios de tratabilidade aplicados a determinação de parâmetros para dimensionamento de processos de tratamento de água de manancial eutrofizado

Eutrophication is a growing process present in the water sources located in the northeast of Brazil. Among the main consequences of these changes in trophic levels of a water source, stands out adding complexity to the treatment to achieve water standards. By these considerations, this study aimed to define, on a laboratory scale, products and operational conditions to be applied in the processing steps using raw water from Gargalheiras dam, RN, Brazil. The dam mentioned shows a high number of cyanobacteria, with a concentration of cells / ml higher than that established by Decree No. 518/04 MS. The same source was also considered by the state environmental agency in 2009 as hypereutrophic. The static tests developed in this research simulated direct filtration (laboratory filters) and pre-oxidation with chlorine and powdered activated carbon adsorption. The research included the evaluation of the coagulants aluminum hydrochloride (HCA) and alum (SA). The development of the research investigated the conditions for rapid mixing, the dosages of coagulants and pHs of coagulation by the drawing of diagrams. The interference of filtration rate and particle size of filtering means were evaluated as samples and the time of contact were tested with chlorine and activated carbon. By the results of the characterization of the raw water source it was possible to identify the presence of a high pH (7.34). The true color was significant (29 uH) in relation to the apparent color and turbidity (66 uH and 13.60 NTU), reflecting in the measurement of organic matter: MON (8.41 mg.L-1) and Abs254 (0.065 cm-1). The optimization of quick mix set time of 17", the speed gradient of 700 s-1 in the coagulation with HCA and the time of 20" with speed gradient of 800 s-1 for SA. The smaller particle sizes of sand filtering means helped the treatment and the variation in filtration rate did not affect significantly the efficiency of the process. The evaluation of the processing steps found adjustment in standard color and turbidity of the Decree nº 518/04 MS, taking in consideration the average values found in raw water. In the treatment using the HCA for direct filtration the palatable pattern based on the apparent color can be achieved with a dose of 25 mg L-1. With the addition of pre-oxidation step, the standard result was achieved with a reduced dose for 12 mgHCA.L-1. The turbidity standard for water was obtained by direct filtration when the dose exceeds 25 mg L-1 of HCA. With pre-oxidation step there is the possibility of reducing the dose to 20 mg L-1.The addition of CAP adsorption, promoted drinking water for both parameters, with even lower dosage, 13 mg L-1 of HCA. With coagulation using SA removal required for the parameter of apparent color it was achieved with pre-oxidation and 22 mgSA.L-1. Despite the satisfactory results of treatment with the alum, it was not possible to provide water with turbidity less than 1.00 NTU even with the use of all stages of treatment

Citação e modernidade em Álvares de Azevedo: do sublime ao dessublime

El estudio de la citación en Lira de los Veinte Años, de Álvares de Azevedo, desde la óptica de Antoine Compagnon e Gerárd Genette, se muestra relevante a los estudios de la Literatura Comparada, en la perspectiva conteporánea, pués el tema provoca la posibilidad de discutir la elaboración de si del(los) otro(s), sucitando imágenes estéticas y de los pensamientos que se aproximan de una noción de tesitura textual muy presente en la modernidad literaria. Este proceso instaura procedimientos de lectura, traducción, autoria y escritura, aún, por ser utilizados, confirman la potencialidad inegable en que se escribi el trabajo poético del escritor. En la primer parte de la obra, se sugieren experiencias com lo bello y lo sublime, advindos del europeu, pero vuelto para una pesquisa de posibilidad discursivas. En la según parte, esa instancia sublimada es puesta en crise, por el sujeto poético cribado por el deseo de tornarse singular. Se instauran en el campo valorativo de los signos románticos elementos desfavorables de sentido diferentes. Dase, así, la problematización puesta por las citaciones que ora, realizan cambios simbólicos, ora, actuan en las márgenes de los textos primeros, desorganizando el material de autoria, desublimandolo, en la irrupción de nuevos cuerpos discursivos y cuerpúsculos cituacionales. En la tecer parte, ligado a Tánatos, como la dimensión por venir, marcando el presentimiento del poeta de que morirá temprano, como también la despedida de él. En esta tesi, se pretende, así, circunscribir como se figura, elabora esa constituición estética azevediana y su escritura, situando cuestiones recortadas por el actor en su obra, las quales remeten a Hegel, Kant y la otras lecturas filosóficas, ali puestas. Tal procedimiento toma la citación como estrategia poética de inscrición del sujeto y de las alteridades que le atravesan, concebiendo eso proceso autoral en la forma de reconstrución de una ciudadela de libros en este aspecto, considerandose el enfoque de Félix Guatarí, la propósito de los nuevos paradigmas y las espacialidades emergentes de estos -, o la biblioteca subjetiva, que se abre en vias y pasagenes. A través de ellas el discurso captura no solamente los objetos poéticos, pero también trazos autobiográficos rasurados, traduciendo la lucha por la visibilidad del sujeto en la formación de su pensamiento poético y estético

Cecília Meireles: mulher ao espelho, imaginário poético e metafísica do amor em Viagem e Mar Absoluto

En el florescer de la modernidad brasileña, surge la poesía de Cecília Meireles, revelando la mujer que opta conscientemente por la labor intelectual, por la especulación filosófica del amor y por la pasión de escribir. La lectura de su obra representa um desafío a la sensibilidad del estudioso de la literatura. En esta disertación, tratamos de ese trabajo em filigranas que la autora realiza. Nos situamos em las obras Viagem y Mar Absoluto como anclas simbólicas de un discurso que nos remite a la relación del poetar com el pensar. Se inserta, así, esa poética ceciliana en um modo filosófico platónico, trayendo elementos simbólicos, míticos, metafóricos capaces de remitirnos a las interpretaciones filosóficas del siglo XX, tal la heideggeriana que entiende la poesía dentro del principio del eterno juego del ser, que es lo del próprio lenguaje. Nuestra preocupación fundamental fue trillar los caminos del erostismo filosófico y la búsqueda de la autora em transcender la rigidez de los límites entre el masculino y el femenino, lanzándose em um imaginario poético cristiano, reinterpretado neoplatonicamente. Se exponen Mujer y Letras al espejo, velando y desvelando marcas e trazos de identidad. Tal juego especular nos ofreció elementos poéticos, estéticos y una experiencia ceciliana del lenguaje del ser, designio de la poesía mísma. De esta nuestra iniciativa, que es también reflejada y reflexiva, reunimos a las Letras la Filosofia, resaltando que ambas de manera diferente - nos dieron acceso a la construcción de esa poesía en que fulguran la escritura, el ser y la naturaleza metaforizada, caracterizando la multiplicidad de sentidos y la pluralidad de voces del presente y del pasado

Cartografias do desejo em asfalto selvagem - engraçadinha, seus amores e seus pecados: humor, erotismo e o pornógrafo no romance rodrigueano

Trata-se nesta dissertação de estabelecer, partindo do pensamento contemporâneo francês da linha deleuziana e guattariana, sobretudo, uma analítica do desejo capaz de reconfigurar o romance de Nelson Rodrigues, Asfalto selvagem: Engraçadinha, seus amores e seus pecados, desterritorializá-lo em relação à tradição crítica e estética, fundada no paradigma realista-naturalista enraizado no pensamento literário brasileiro, especificamente no século XX. Movemo-nos por discussões sobre o autor e sobre o romance, empreendidas por Rolnik, interlocutora de Guattari, o qual está ligado aos novos paradigmas estéticos, à questão da produção de subjetividades, à micropolítica, às multiplicidades e às minorias. Buscamos contribuir para esse redimensionamento, colocando-nos na perspectiva cartográfica e rizomática para surpreender, em Asfalto, seus processos de subjetivação, incidindo sobre as singularidades selvagens, considerando os conceitos de Foucault, aplicados à construção literária enquanto espaço heterotópico, configurando a experiência do fora, como princípios estéticos. Veremos que as personagens, com foco em Engraçadinha, funcionam, como pequenas máquinas desejantes, Corpos sem Órgãos, moléculas desestabilizando as formações molares. Destarte, Nelson Rodrigues, na perspectiva da produção autoral, torna-se o pornógrafo, o literato iterador, como agenciador de uma palavra perversa, para além dos dogmas, da cena romantizada, originando, em sua poética, a revelação da obs-cena, a obscenidade, como crítica às instituições falidas. Trazemos, nesse sentido, referências de Bataille, quanto ao que na atividade estética se relaciona com o excedente da visão, relacionados ao espaço tático-ótico, concepção deleuziana referentes ao corpo-linguagem, pornografia, pornógrafo, narrativas abomináveis. Acompanhamo-nos, pois, dos conceitos da problemática da diferença e da alteridade, repercutindo na larvaridade, nas afecções, que abrem vias comunicantes com fenômenos extremos, atuantes em torno do mesmo e do outro, trazendo a rizomaticidade do mal e da monstruosidade para a construção estética de Asfalto selvagem, vistos sob a ótica de Bataille, Deleuze, Baudrillard, em ensaios que rompem o olhar estrutural em torno da obra e oferecem subsídios para a construção de uma cartografia outra, o território do ficcional, habitado por um povo por vir, na perspectiva tratada por Deleuze e por Blanchot

Dinâmica de tempos curtos aplicado ao modelo de ising diluído por sítio em duas dimensões

Existem vários métodos de simulação para calcular as propriedades críticas de sistemas; neste trabalho utilizamos a dinâmica de tempos curtos, com o intuito de testar a eficiência desta técnica aplicando-a ao modelo de Ising com diluição de sítios. A Dinâmica de tempos curtos em combinação com o método de Monte Carlos verificou que mesmo longe do equilíbrio termodinâmico o sistema já se mostra insensível aos detalhes microscópicos das interações locais e portanto, o seu comportamento universal pode ser estudado ainda no regime de não-equilíbrio, evitando-se o problema do alentecimento crítico ( critical slowing down ) a que sistema em equilíbrio fica submetido quando está na temperatura crítica. O trabalho de Huse e Janssen mostrou um comportamento universal e uma lei de escala nos sistemas críticos fora do equilíbrio e identificou a existência de um novo expoente crítico dinâmico θ, associado ao comportamento anômalo da magnetização. Fazemos uima breve revisão das transições de fase e fenômeno críticos. Descrevemos o modelo de Ising, a técnica de Monte Carlo e por final, a dinâmica de tempos curtos. Aplicamos a dinâmica de tempos curtos para o modelo de Insing ferromagnéticos em uma rede quadrada com diluição de sítios. Calculamos o expoente dinâmicos θ e z, onde verificamos que existe quebra de classe de universilidade com relação às diferentes concentrações de sítios (p=0.70,0.75,0.80,0.85,0.90,0.95,1.00). calculamos também os expoentes estáticos β e v, onde encontramos pequenas variações com a desordem. Finalmente, apresentamos nossas conclusões e possíveis extensões deste trabalho
