Influência dos odores de gato e de cobra no comportamento defensivo e expressão de fos do sistema hipotalâmico de defesa de camundongo

Studies using neuronal tract-tracer in rat have shown that the anterior hypothalamic nucleus, dorsomedial division of the ventromedial nucleus of the hypothalamus and dorsal premammillary nucleus are highly connected. When the rat is exposed to predator or its odor these nuclei have shown a expression of Fos and their lesion reduces defensive behavior against predator. This set of nuclei was named the Hypothalamic Defense System. However, little is known about the response of this system to the odor of different predators or its role in mice. In this work, we exposed Swiss mice to two different predators odor (cat and snake) to verify the Fos expression in the Hypothalamic Defense System, as well as the defensive behaviors displayed. The analysis showed that the mice exposure to cat odor had an increased expression of Fos protein compared to control, while those exposed to snake odor showed no rise in Fos expression, which was corroborated by the behavioral data. Our results indicate that this distinct circuit in mice seems to act differentially to odorous stimuli of different predators, causing distinct behavioral responses of mice and that the odor of snake seems not to be perceived by Swiss mice as a threatening stimulus.

Algoritmo eficiente para aquisição de sinais de GPS por software

O NAVSTAR/GPS (NAVigation System with Timing And Ranging/Global Po- sitioning System), mais conhecido por GPS, _e um sistema de navegacão baseado em sat_elites desenvolvido pelo departamento de defesa norte-americano em meados de 1970. Criado inicialmente para fins militares, o GPS foi adaptado para o uso civil. Para fazer a localização, o receptor precisa fazer a aquisição de sinais dos satélites visíveis. Essa etapa é de extrema importância, pois é responsável pela detecção dos satélites visíveis, calculando suas respectivas frequências e fases iniciais. Esse processo pode demandar bastante tempo de processamento e precisa ser implementado de forma eficiente. Várias técnicas são utilizadas atualmente, mas a maioria delas colocam em conflito questões de projeto tais como, complexidade computacional, tempo de aquisição e recursos computacionais. Objetivando equilibrar essas questões, foi desenvolvido um método que reduz a complexidade do processo de aquisição utilizando algumas estratégias, a saber, redução do efeito doppler, amostras e tamanho do sinal utilizados, além do paralelismo. Essa estratégia é dividida em dois passos, um grosseiro em todo o espaço de busca e um fino apenas na região identificada previamente pela primeira etapa. Devido a busca grosseira, o limiar do algoritmo convencional não era mais aceitável. Nesse sentido, um novo limiar foi estabelecido baseado na variância dos picos de correlação. Inicialmente, é feita uma busca com pouca precisão comparando a variância dos cinco maiores picos de correlação encontrados. Caso a variância ultrapasse um certo limiar, a região de maior pico torna-se candidata à detecção. Por fim, essa região passa por um refinamento para se ter a certeza de detecção. Os resultados mostram que houve uma redução significativa na complexidade e no tempo de execução, sem que tenha sido necessário utilizar algoritmos muito complexos.

A responsabilidade civil extracontratual do estado na prestação de serviços públicos de saúde

This study aims to examine the Brazilian legal model for the non-contractual liability of the state in providing public health services, from the perspective of threedimensional theory of law. Up based on bibliographical and documentary research, with emphasis on legislation, doctrine and Brazilian jurisprudence, the following conclusions were reached. The right to health is typified in the Constitution as a social fundamental right, and understands the pretension to obtain from the State, the supply of goods or the provision of services that reduce the risk of disease and other health problems; or promote, protect and recover the physical and mental well-being. Once violated the fundamental right to health, provides the managed, among other fundamental guarantees, the non-contractual liability of the state. The provision of public services by the state can be made directly through the Direct or Indirect Public Administration, or by recourse to private entities. In any case, the provision of public health services is entirely subordinate to the principles of administrative law and should be fully funded by tax revenues. As the provision of public health services is part of the administrative activity of the State, there is no way to exclude the application of the guarantee of non-contractual liability of the state in the face of the damage suffered by administered as users of these services. Therefore, it applies the theory of administrative risk, even in the event of harmful and illegal state failure.

As escolas polivalentes do Triângulo Mineiro e Alto Paranaíba (MG): sondagem vocacional no projeto desenvolvimentista civil-militar (1965–1976)

This study has as object eight state vocational schools located in Araguari, Araxá, Frutal, Ituiutaba, Monte Carmelo, Patos de Minas, Uberaba and Uberlândia, in Minas Gerais. The period analyzed comprises the years from 1965 to 1976, from the signature of the Agreement 512-11-610-042 beteween the Ministry of Education and Culture (MEC) and the American Agency for International Development (USAID), which started a series of other agreements, and actions ending up with the creation of the Expansion and Improvement of High Schools Program (Programa de Expansão e Melhoria do Ensino Médio - PREMEM) and, from this, the Vocational Schools. The upper limit of the study, 1976, was the year when these agreements, known as MEC/USAID agreements ceased. The Vocational Schools were characterized as vocation probing schools, directing the professional formation of the population in general, which would happen a posteriori, turning it shorter and more effective, since the labor market would demand, urgently, capable professionals for an expanding economy. The project of Vocational Schools had a national scope, and foresaw, for its unfolding, the complete substitution of State Schools for the new model, called “multi-curricula”. The theme Vocational schools was the object of my Master’s degree study, when I focused the State School Guiomar de Freitas Costa, in Uberlândia. That study raised questionings and concerns that resulted in the central problem of the thesis presented here: understanding the measure in which such schools integrated the country’s development project – mostly in the first half of the military rule – and to understand its structure, functionality and efficacyThe development of the study presented here, demanded the use of several sources: 1) specialized literature about the topics presented, i.e., the situation of national education in a temporal analysis, the political, economical and social context, research methodologies, the theory of human capital, vocational teaching, pedagogical trends and practices, agreements MEC-USAID and PREMEM; 2) national, state and county laws related to the discussion: laws of national education directives and basis, decrees and reports stating about the program of technical cooperation between Brazil and the United States of America, the Program of Expansion and Improvement of Teaching (PREMEM), formation of professors, establishment of Vocational Schools and educational planning; 3) documentation of school archives: books of minutes of Collegiate and of faculty and staff, registrar books with final scores, enrolment, visits of inspector, accounting books, punch clock records, student, professor and staff occurrences, inventory, class schedules, school year calendar, school rules, class reports, payment rolls, bills of sales, exchanged mail, personal documentation of professional personnel, documents of land acquisition, blueprints, manuals of PREMEM, didactic materials/resources used in classes, books available in the school library, structured evaluations for follow-up of school processes, pictures of events, texts prepared for special dates, and news from the official newspaper and, finally, 4) national and local press reports, especially from Folha de São Paulo, Correio de Araxá, Correio de Uberlândia and Lavoura e Comércio (Uberaba). The proposition of Vocational schools was conciliate theoretical and practical formation through an active education permeated by technological resources. The contact with knowledge and several practical activities under professional supervision, the student would identify the knowledge area that would interest him the most and his aptitude. This formation in primary school would make way for the vocation studies in high school, which became mandatory by the law 5.692/71, that reformed school education from the previous levels of elementary, middle high and high school. However, the multi-curricula proposal that would be spread to the other public schools in the country ended up succumbing to the model already established. From its ephemeral existence, maybe the Vocational Schools have not reached the more general goals in political, economic and social aspects; however, this study demonstrated that, for the people that, directly or indirectly, had contact with such schools, a legacy of vocational and quality teaching was made, so much so, that forty years after the end of that proposal, they are still remembered.

Estratégias de posicionamento: as alianças e as negociações empregadas pelos agentes fomentadores no processo de implantação da TV digital no Brasil

As estratégias de posicionamento são essenciais para o alcance de vantagem competitiva nos diferentes setores das atividades concorrenciais. O objetivo do trabalho está em investigar os discursos empregados pelos seis principais agentes envolvidos no processo de implantação da TV digital no Brasil e, concomitantemente, analisar e discutir os interesses de cada um desses agentes como participativos da decisão técnica/política da escolha do padrão de TV digital. Por intermédio de pesquisa exploratória de natureza qualitativa, análise pós-factum, com emprego da técnica de entrevista embasada na fusão de três referenciais teóricos relacionados ao posicionamento estratégico, especificamente, a Estratégia Decidida Continuamente, Nova Retórica e Análise Retórica, buscou-se delinear as diferentes etapas do processo que culminaram na outorga do padrão digital da TV brasileira em 02 de dezembro de 2007. A análise dos resultados da pesquisa aponta que a adoção do padrão japonês ocorreu em perfeita consonância com os interesses formados pela aliança dos Radiodifusores e do Governo Federal, em detrimento dos interesses do Coletivo Intervozes, da Indústria de Telecom e da Academia, sendo que, para a Indústria de Eletro-eletrônicos não houve interferências significativas no seu modelo de negócio. Esse caso constitui um instrutivo exemplo do processo de negociação no emprego das estratégias por parte dos executivos atuando como agentes retóricos na defesa dos interesses de suas respectivas organizações.

Cooperação e competição entre políticas no Brasil: os custos da governabilidade no presidencialismo de coalizão

Public policies have been studied in the various fields of humanities and social sciences, from different theoretical and technical aspects. However, there is still a lack of studies that incorporate the dimension that encompasses the political action and its interference in such actions, also recognizing the importance of the institutional setting of the Brazilian presidential model in implementing these policies. This fragmented and multiparty system has led to power heterogeneous sets of political parties. Thus, the ministerial offices, more than assisting the President´s government project, manage particularized agendas, which are party biased and have the influence of interest groups in hegemonic themes addressed by government agencies. When these agendas operate in sectoral and specialized policies, the friction level is apparently low. However, when this occurs in intersectoral actions, such as in regional development, there is evidence of strong signs of competition among government agencies, which in theory, should operate in an integrated manner. Although this is not a specific feature of Luiz Inacio Lula da Silva´s government- the period to be studied- there was similar behavior in Fernando Henrique Cardoso´s presidency, one realizes that the expansion of coalition on behalf of governance is increasingly interfering in the outcome of intersectoral public policies, due to these multiple arguments in action. In order to understand these processes, this study focused on the Sustainable and Integrated Development Programme for Differentiated Meso-Regions (PROMESO), part of the National Policy for Regional Development (NPRD). The program provides interface with various government agencies and their public policies in a clear intersectoral design. The research sought to identify and analyze the relationships between government agencies and their programs with interest groups, whether political parties or other segments of civil society, highlighting the logic of favoritism, which poses in second place the integration of actions in the intersectoral policies. Therefore, besides the theoretical debate that incorporates several categories of political science, public administration, public policy, geography and economics, the study focused on secondary sources, using different government agencies databases in order to raise information. It was observed that the interference of partisan politics has been disastrous for some public policies. Thus, the research confirms that cooperative character is fragile within government agencies, often limited to official documents, and that there is indeed, a striking feature of competition, especially when it comes to transversalized policies

A implementação de ações de integração na segurança pública: o caso das polícias civil e militar do Rio Grande do Norte

The research aimed to understand the challenges for the implementation of the proposed integration between the Civil Police and the Military Police in Rio Grande do Norte to the proposals of the SUSP. This study aimed to explore the gap with regard to the deepening of the possible causes that may hinder the implementation of integrated working between the police in public security, through a specific analysis on the state of Rio Grande do Norte. Was based on a theoretical framework that includes policies: general concepts, the steps of a public policy, the implementation stage , public security : conceptual definitions, policies on security in Brazil, the structure of public security in Brazil and systems police, Military Police x Civil Police: Roles and conflicts , integrating public security: the challenges to be overcome, the Unified public Safety (SUSP) and the main difficulties in the integration of the police. Being classified as to the purposes as an exploratory research on how to approach ranks as qualitative. The research unit was the Center for Integrated Operations Public Safety (CIOSP) through three subjects who were the chief CIOSP, the representative of the military police acting with the CIOSP, and representative civil police also active with the CIOSP. These subjects were chosen because of the understanding that individuals occupying senior positions would have more ability to respond to questions that guide the research problem. Data were collected through a set of interviews, qualitative data analysis was performed based content analysis, based on the definition of categories of analysis, gated time cross. With the results, it was revealed that the main problems of integration between the state police are treatment protocols, lack of political will and lack of infrastructure. The relationship between the Military Police and Civil Police in Rio Grande do Norte has differing cultural aspect, but can be considered as good value, professionalism and integrated operations. The implementation of CIOSP-RN followed the characteristics of the top-down model, the main difficulties in implementing the proposals of the SUSP, lack of own resources, the lack of standardization in public safety and the lack of professional training of public safety. It was concluded that with respect to the challenges to the implementation of the proposed integration between the Civil Police and the Military Police in Rio Grande do Norte to the proposals of the SUSP, the actions follow the characteristics of the top-down model, with no autonomy of administrators public to say in decisions, which restricts the view of the public safety of the state

A ampla defesa e o contraditório aplicados ao inquérito policial

Trata-se de um estudo sistêmico e metódico dos institutos da ampla defesa e do contraditório aplicados no bojo de um inquérito policial à luz dos demais princípios constitucionais fundamentais. Far-se-á um olhar comparativo entre as normas e demais fatores jurídicos, políticos, econômicos e sociais do Brasil e de Portugal, bem como referências subsidiárias de outros países da Europa e do mundo. O tema gira em torno do sistema processual penal brasileiro no que tange às investigações preliminares da polícia judiciária. Estabelece como ponto de partida a efetivação do Estado Democrático de Direito no processo de construção de uma sociedade comprometida no senso de igualdade e justiça. Para tanto, avaliaremos a conveniência de se instituir aqueles princípios no texto constitucional e respectivas leis como forma de dar concretude à formação da culpa do acusado ainda na fase policial; ou, pelo menos, para promover uma investigação criminal livres de quaisquer vícios. Também será necessário refletir sobre a evolução da persecução penal no mundo e no Brasil para que possamos, a partir de uma análise comparativa, avaliar os aspectos positivos e negativos que devem ser repetidos ou rechaçados. Proporemos uma mudança de paradigma de investigação criminal, elegendo o órgão ministerial como condutor das investigações, em contraponto ao atual modelo brasileiro que deposita essa prerrogativa exclusivamente nas mãos da polícia judiciária, para então concluirmos se vale a pena uma alteração normativa lastreada na otimização dos resultados no combate à criminalidade tendo o inquérito policial como instrumento de controle. Nesta esteira, feito o breve estudo da evolução histórica dos institutos, passaremos por uma reflexão mais moderna do Estado Garantidor pautado no senso democrático atual, para, então, esmiuçar a merecida atenção dos princípios fundamentais constitucionais e finalmente mergulhar nos principais aspectos do inquérito policial, sempre propondo a eventual aplicabilidade da ampla defesa e do contraditório como forma de compatibilizar de vez com a noção de democracia plena dos institutos penais. Em seguida, iremos colacionar os resultados da pesquisa empírica feita por meio de entrevistas com profissionais de alta envergadura jurídica, os quais apresentarão suas perspectivas quanto ao tema e terão suas manifestações analisadas de forma qualiquantitativa. Concluiremos o trabalho com as reflexões finais.

Combater as secas e defender as florestas a natureza nos desafios da ciência e da técnica para modernizar o Brasil (1889 a 1934)

In the first decades of 20th century the just instituted Brazilian Republic faced the challenge to modernize the country. Considering that the progress was associated with the exhaustion of the forest reserves and with climatic changes, two big issues were seen as fundamental: To Fight the Droughts and To Defend the Forests; headed by professionals who were dedicated to these ideals. This research starts from the premise that these were the main challenges enforced by nature to the Brazilian development; the general objective was delimited in the search to understand the meaning and the conception of the natural world by this group of professionals who faced the shock between modernizing the country and conserving its natural resources. Aiming to contribute with the construction of the Brazilian environmental history and to bring historical elements to the debate about the environment in the country, the author concentrates his attention to the analyses, the discussions and the actions that preceded the regulation on the use of natural resources and the implementation of the environmental legislation in Brazil, occurred in 1934. The investigation uses as methodological basis the theoretical directions of environmental history, using sources of data still little explored and valued. In such way, it is taken as starting point some published papers about this subject during the period between 1889 and 1934 in two technical magazines the Revista Brazil Ferro-Carril and the Revista do Club de Engenharia. National engineering played a basic role in this process while arguing, projecting and constructing the development. The formulated proposals, after being divulged, had fomented the interchange with other professionals and had favored the advance of ambient questions in Brazil, in the sense to preserve natural resources, to construct more harmonic relations between the society and the nature and to equate the development with the environment preservation

Henrique Novaes: técnica, território e cidade em uma trajetória profissional: Brasil, primeira metade do século XX

The career of civil engineer Henrique de Novaes, a remarkable figure in the academic, technical and political fields, demonstrates its extensive and relevant work across Brazil in the first half of the twentieth century. It covered from the design of water supply and sewage works, road and rail transport networks, works against drought in the Northeast, hydroelectric and harbor facilities to the urbanization planning and architectural projects, which displays a systematic and multiple production. City and territory conformed to his fields of verification, practical and above all, transformation. The search for understanding of the inclusion of a social actor in this process thus contributes to the specific analysis of the doings of Henrique de Novaes, who graduated at Polytechnic School of Rio de Janeiro in 1906. From a polymorphic activity in different scales, one tries to figure how, through academic education or professional practice, urban history in Brazil can be told or built. The introduction of technological innovations matched the purposes of planning and urban sprawl, as well as met the specifications of regulation and institutionalization of public infrastructure services at the time. The overall plans proposed by the engineer thought of the city as a whole, interconnected to the structural networks. At the same time, the knowledge of a larger physical scale the territory bounces back in the urban in a relationship of reciprocity and completeness. The objective research, therefore, tries to understand the roles played by Henrique de Novaes s works and academic education in the accomplishment of systematic modernization of Brazilian urban space and territory, recovering a little known historical figure by current historiography. It is proposed, as methodological axis, that the study of this professional career configures itself as an essential element for understanding the idea of progress embodied in the technical studies and proposals for improvements and sanitation nationwide in the first half of the twentieth century . The primary sources for the construction of this analysis were technical articles in journals of the period ( Clube de Engenharia , Viação e Revista Brasileira de Engenharia ), and technical reports, government messages, newspaper articles published at the time, autobiographical reports and the engineer s verbal communications with relatives. The work is structured in three chapters: "Biographical traces, academic education and 'technical and political' activities" illustrates the initiation into the technical, public and political environment; Chapter 2, "Technique and territory" outlines his network understanding through sanitation and transport services; Chapter 3 "Technique and City" describes the influence of polytechnics knowledge on the propositions of modernization of cities; Finally, "Final Thoughts: An Evaluation," presents an overview of the affiliations and practice of an engineer in the different scales, and its contribution to the modernization of Brazilian urban and territorial space

Material para construção civil a partir de lodo de estação de tratamento de água, lama de polimento de mármore e resíduo de produção de cal

The rapid population growth is the great motivator for the development of the construction industry and the increased demand for drinking water, resulting in a gradual increase in the generation of solid waste. Thus, this work was carried out in order to recycle industrial and municipal wastes incorporating them into materials for civil construction. The composite produced from water treatment sludge and marble polishing mud, applying lime production waste as a binder, was evaluated for its mechanical performance and its morphological structure. The raw materials were characterized for their chemical composition, mineralogy, morphology, particle size and also the moisture content. With the featured materials nine compositions have been developed varying the content of the water treatment sludge between 25 to 50%, marble polishing mud between 35 to 50% and the lime production waste between 10 to 30%. The composites were subjected to mechanical strength tests, water absorption, chemical and mineralogical composition and morphology. The developed materials presented, on the 3rd day of hydration, maximum strength value of 4.65 MPa, the 7th day 6.36 MPa, on the 14th day 6.74 MPa, the 28th day 5.98 MPa, on the 60th day 8.52 MPa at 90th day 11.75 MPa and 180th day 12.06 MPa. The water absorption values after 28 days of hydration ranged from 16.27% to 26.32% and after 90 days, from 13.57% to 23.56%.
