Foucault e a (bio) política: possibilidades e metamorfose de um conceito

The fundamental question developed in this research is to consider the possible meanings of biopolitics in the thought of Michel Foucault. In the first chapter of this study seeks to examine the rationality of biopower. It is able to show the rationality of acting as a social machinery for the manufacture of the subjectivity of individuals, biopolitics as a producer of bodies and subjectivity. The theme of biopolitics appears as inspiration of Nietzsche's metaphor of war. The idea that history is the war for dominance of the bodies. In the second chapter, the (bio) political will and political thought of resistance, fighting criticism as an attitude of revolt of the subject before his condition subjugated. The biopolitical here is intended as a conceptual tool for reading the thought / Foucault's work. A resistance that can be thought of as a biopolitical as a "refractoriness reflected". The third chapter will seek to show how the Foucault argues that power was already present the ethics of self-care. If the subject is a product, is captured by the discourse of biopower that manufactures its subjectivity, self care, it's time to think about the inner contents. Self care is something that offers resistance, as a possibility to think that these contents are constructed historically, and that therefore it is possible to reestablish the self-care is a policy of fighting these sedimented content that promotes colonization of the subjects. You can move from ruler to ruled itself, although this pursuit of liberty is always unfinished, always be a tension, a desire for freedom that can be undertaken not as a state, but at least the minimum and temporarily in other forms of existence, and other ways of relating, other ways of sociability, friendship, sexuality

Desenvolvimento e caracterização de dispositivos para reposição de filmes finos por descarga em cátodo oco

In the present work we use a plasma jet system with a hollow cathode to deposit thin TiO2 films on silicon substrates as alternative at sol-gel, PECVD, dip-coating e magnetron sputtering techniques. The cylindrical cathode, made from pure titanium, can be negatively polarized between 0 e 1200 V and supports an electrical current of up to 1 A. An Ar/O2 mixture, with a total flux of 20 sccm and an O2 percentage ranging between 0 and 30%, is passed through a cylindrical hole machined in the cathode. The plasma parameters and your influence on the properties of deposited TiO2 films and their deposition rate was studied. When discharge occurs, titanium atoms are sputtered/evaporated. They are transported by the jet and deposited on the Si substrates located on the substrate holder facing the plasma jet system at a distance ranging between10 and 50 mm from the cathode. The working pressure was 10-3 mbar and the deposition time was 10 -60 min. Deposited films were characterized by scanning electron microscopy and atomic force microscopy to check the film uniformity and morphology and by X-ray diffraction to analyze qualitatively the phases present. Also it is presented the new dispositive denominate ionizing cage, derived from the active screen plasma nitriding (ASPN), but based in hollow cathode effect, recently developed. In this process, the sample was involved in a cage, in which the cathodic potential was applied. The samples were placed on an insulator substrate holder, remaining in a floating potential, and then it was treated in reactive plasma in hollow cathode regime. Moreover, the edge effect was completely eliminated, since the plasma was formed on the cage and not directly onto the samples and uniformity layer was getting in all sampl

Treinamento muscular inspiratório para asma: revisão sistemática com metanálise

In asthmatic, the lung hyperinflation leaves the inspiratory muscle at a suboptimal position in length-tension relationship, reducing the capacity of to generate tension. The increase in transversal section area of the inspiratory muscles could reverse or delay the deterioration of inspiratory muscle function. Objective: To evaluate the evidence for the efficacy of inspiratory muscle training (IMT) with an external resistive device in patients with asthma. Methods: A systematic review with meta-analysis was carried out. The sources researched were the Cochrane Airways Group Specialised Register of trials, Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 11 of 12, 2012), MEDLINE, EMBASE, PsycINFO, CINAHL, AMED, ClinicalTrials.gov and reference lists of articles. All databases were searched from their inception up to November 2012 and there was no restriction on the language of publication. Randomised controlled trials that involved the use of an external inspiratory muscle training device versus a control (sham or no inspiratory training device) were considered for inclusion. Two reviewers independently selected articles for inclusion, evaluated risk of bias in studies and extracted data. Results: A total of five studies involving 113 asthmatic patients were included. Three clinical trials were produced by the same group. The included studies showed a significant increase in maximal inspiratory pressure (MD 13.34 cmH2O, 95% CI 4.70 to 21.98), although the confidence intervals were wide. There was no statistically significant difference between the IMT group and the control group for maximal expiratory pressure, peak expiratory flow rate, forced expiratory volume in one second, forced vital capacity, sensation of dyspnea and use of beta2-agonist. There were no studies describing exacerbation events that required a course of oral and inhaled corticosteroids or emergency department visits, inspiratory muscle endurance, hospital admissions and days of work or school. Conclusions: There is no conclusive evidence in this review to support or refute inspiratory muscle training for asthma, once the evidence was limited by the small number of studies included, number of participants in them together with the risk of bias. More well conducted randomized controlled trials are needed, such trials should investigate respiratory muscle strength, exacerbation rate, lung function, symptoms, hospital admissions, use of medications and days off work or school. IMT should also be assessed in the context of more severe asthma

Jardim do Seridó: A construção dos espaços públicos na Veneza Seridoense nas primeiras décadas do século XX

As the space and the city are objects of desires, interests, seduction, sedition, appropriations, battles, victories, defeats, require to be analyzed historically. This research investigates and discusses the construction of public spaces in Jardim do Seridó City, backwoods of Rio Rio Grande do Norte, in the first decades of twentieth century, when the municipality was chaired by Heráclio Pires Fernandes, who ruled from 1917 to 1930 and was graduated from the University of Pharmacy of Recife, where he contacted the architectural, political and artistic influences circulating in the capital of Pernambuco. In the first decades of the twentieth century, the space of Jardim earns statements and practices, against the discourse of modernity, which sought to justify the title of Veneza Seridoense . At the time, the city had undergone several transformations in its public spaces through the construction of the Butchery, the Market, the Public Roads connecting the city to other urban centers, the building of the Bridge of the Pedra Lavrada Farm, the Elementary School Antônio de Azevedo , the creation of the Music Band Euterpe Jardinense , the Literary and Recreative Guild, the pavilion, the paving, tree planting, lighting, streets naming and listing of the annual painting of households, the arrival of automobiles, mail and telegraph. The construction of these new sceneries and the arrival of equipments generated impacts in the daily life of the population and were received differentiated ways by individuals involved in the process, which shows the tension between old and new, the relationship between history and space

Estresse entre professoras do ensino fundamental de escolas públicas estaduais

O artigo relata pesquisa que visou, entre outros objetivos, identificar a presença do estresse, a sintomatologia e as fases apresentadas pelos professores de 1ª a 4ª série do Ensino Fundamental atuantes em escolas públicas estaduais de uma cidade do Interior de São Paulo. Participaram do estudo 175 professores, perfazendo, aproximadamente, 70% dos profissionais de Ensino Básico I (PEB-I) em atuação no município. Para obtenção dos objetivos foram utilizados dois instrumentos de coleta de dados: o ISSL (Inventário de Sintomas de Estresse) e um questionário para caracterizar a população pesquisada. A pesquisa revelou que 56,6% dos professores estão experimentando estresse, cujos principais sintomas presentes são: sensação de desgaste físico constante, cansaço constante, tensão muscular, problemas com a memória, irritabilidade excessiva, cansaço excessivo, angústia/ansiedade diária, pensar constantemente em um só assunto e irritabilidade sem causa aparente.

Caicó: uma cidade entre a recusa e a sedução

This research has as object of study the city of Caicó, Rio Grande do Norte State, between the middle part of the decade of 1920 and the beginning of 1930. It intended to perceive the projects thought to the city of Caicó as well as the challenges due to the new ideas of modernity that were circulating around the contemporary world. So it consists in an important historical exercise about the relation between history and space in to the extent that itself comes to surface a city deals by diverse angles whose perspectives can be read in several "fragments of memory", such as newspapers, trials-crime, reports, memories, books, etc., those show the tension between the traditional and the modern way of life one. In this way, it´s tried to transform the space, giving it a new reference, inspired in what occurs in the Brazilian big cities and around the world, through the use of the techniques, of the electricity, of the movies, of the press, cars, medicine and so on. At the same time in that is necessary-itself deal with the permanencies such as the old manners and the droughts and theirs "flagellated" people. Therefore, it is in this difficult phase that is tried legitimize the city of Caicó as the "Capital of the Seridó", in the threshold between the refusal and the seduction

Medo de dentista em cena: uma análise de produções cinematográficas

The fear related to dental procedures can be acquired through disturbing experiences and/or negative cultural influences related in experiences of previous generations. Such influences may be present in diverse forms of cultural expression: in the cinema, plastic arts, music, literature, and diverse vehicles of printed and visual media. This research aimed investigates the images of fear related to the dental service and dentist in motion pictures. The study has qualitative approach, which used the documentary analysis of movies. The data collection was accomplished through research in the Internet by means of the Google tool (http://www.google.com.br), using the describing words filme and dentista . A total of 44 films were found. Of these, after selective criterion for films with scenes showing interaction between dentist and patient in the execution of clinical procedure, only 24 films were enclosed. Then, these were registered in data base created for this research. After second selective criterion of inclusion (scenes with suggestion of dental anxiety), 15 films remained. As regards cinematographic gender, the films with scenes showing "dental anxiety" varied between comedy (8), horror (3), drama (2), thriller (1) and childish (1). Of these films, scenes with images of situations that suggest fear of the dentist and his job were selected and described. The images were categorized by the identification of negative characteristics that incite "dental anxiety". Then, the classification of the categories was proceeded detaching the most recurrent characteristics in the scenes: situation of fear in the waiting-room; pain; instrument coarse/rudimentary; coarseness of the dentist; torture; and low qualification technique. The waiting-room was observed as a place of great tension, due to the noises coming from the dental attendance. The pain related to the Dentistry was the predominant subject in the majority of films (14), associated to others negative characteristics. The rudimentary aspects of procedures and instruments, and the coarse attitudes of the professional could be observed too. The dentist was characterized as confused, sadist, violent, insensitive, incompetent person and disturbed. Such results suggest that, despite the technological advances of the profession, the image of the dentist and his job is still transmitted in a negative way aspect and reinforces the dental anxiety

Influência da velocidade de avanço do rebolo nos danos de aços endurecidos retificados

A tendência mundial é o aumento da produtividade e da produção de peças cada vez mais sofisticadas, com elevado grau de tolerância geométrica, dimensional, com bom acabamento superficial, com baixo custo. A retificação é responsável pelo acabamento final no processo de usinagem de um material. No entanto, danos gerados nesta fase de produção comprometem todos os recursos utilizados nas fases anteriores. Grande parte dos problemas ocorridos na retificação deve-se à enorme temperatura gerada pelo processo devido às condições de usinagem. Atribui-se à velocidade de avanço, que está diretamente relacionada com a produtividade, os danos ocorridos na retificação, ficando esta variável limitada até valores que não proporcione danos. Neste trabalho, através da variação da velocidade de avanço no processo de retificação cilíndrica externa do aço ABNT D6, racionalizando a aplicação de dois fluidos de corte e usando um rebolo superabrasivo de CBN (nitreto de boro cúbico) com ligante vitrificado, avaliou-se a influência da velocidade de avanço nos danos superficiais de aços endurecidos. Os resultados permitiram concluir que a velocidade de avanço associada a uma eficiente refrigeração e lubrificação, não provocou danos térmicos (queima, trincas, tensões de tração) ao material. Tensões residuais e a rugosidade do material retificado apresentaram uma correlação com as condições de usinagem. O trabalho concluiu ser capaz um aumento dos índices de produtividade sem provocar danos nos componentes retificados.

Glucose consume and growth of E. coli under electromagnetic field

E. coli,em caldo glicosado,foi submetida a campo eletromagnético de intensidade 5G, gerado por fonte de tensão alternada de 60 Hz . Os crescimento e consumo de glicose foram avaliados através do teste não-paramétrico de Mann-Whitney para comparação de dois grupos. Após 8 h de exposição encontraram-se menor valor da glicose residual e maior turbidez nos tubos expostos ao campo evidenciando efeito positivo deste. A causa deste efeito no consumo da glicose pode ser pela estimulação de sistema de transporte de glicose, como a Difusão Facilitada ou por um tipo de fenômeno chamado ressonância ciclotrônica. O aumento do crescimento pode ser pelo encurtamento da lag phase e estimulação da log phase.
