Depuis le début de son histoire, l’être humain cherche, pour de nombreuses raisons à s’associer et développer le milieu où il vit. Ces caractéristiques culminèrent dans les phénomènes de mondialisation et de révolution technologique responsables de la diminution des distances physiques et temporelles du monde contemporain. Ces facteurs ont stimulé les processus d’intégration régionaux, lesquels ont pour but le renforcement de ses adhérents face à la nouvelle réalité mondiale. Parmi ces processus, on note le Mercosur qui vise à la création d’un marché commun entre l’Argentine, le Brésil, le Paraguay et l’Uruguay. Fondé sur l’intergouvernabilité et avec une structure organisationnelle définie, ce bloc économique possède un cadre normatif en évolution, cherchant constamment la sécurité juridique dans divers secteurs. Quant à la protection des droits de propriété intellectuelle, on constate une ancienne préoccupation de la région sur le thème. Toutefois, le peu de normes existantes au sein du bloc confèrent des droits subjectifs minimaux et la plupart d’entre eux ne sont pas intégrés dans les législations nationales, lesquelles sont alignées sur les traités internationaux. Dans ses relations internationales, le Mercosur a une longue histoire de négociations avec l’Union Européenne et une histoire plus modeste avec le Canada, dans lesquelles l’attention portée aux droits de propriété intellectuelle n’est pas uniforme. De plus, sa participation dans les organismes internationaux responsables de ces droits est faible. Dans ce contexte, même avec un futur incertain le Mercosur présente de grandes expectatives. Toutefois, la préoccupation à protéger les droits de propriété intellectuelle est présente et réelle et commence à prendre de l’ampleur dans ses relations internes et externes.

Amenazas como Siria, Irán y el PKK fueron relevantes al momento de forjar una alianza entre Turquía e Israel a mediados de los noventa. Con la firma de varios acuerdos en el ámbito militar se fortaleció la relación bilateral en materia de seguridad. Sin embargo, la llegada de un nuevo gobierno a Turquía en 2002 generó un cambio en materia de política exterior, especialmente con Israel. La monografía sustentada bajo los postulados de la Teoría del Balance de las Amenazas concluye que la ruptura de la alianza se dio por el cambio en la política exterior de seguridad turca, el bloqueo a Gaza por parte de Israel en 2008 y el ataque a la Flotilla de Gaza en 2010, conduciendo a una transformación en los acuerdos militares pactados para la seguridad y estabilidad de ambos países en la región de Medio Oriente.

Esta monografía analiza la influencia del Crimen Organizado Transnacional en la Triple Frontera compartida por Argentina, Brasil y Paraguay y sus decisiones en Política Exterior durante 1996 y 2006. Se explica cómo el Crimen Organizado Transnacional y sus efectos en la gobernabilidad de los Estados pueden ser un motivo para el análisis de la situación como un Complejo de Seguridad Regional. A partir de la conceptualización de Seguridad Regional de Barry Buzan y Ole Waever y de Robert Stewart y Derrick Frazier, se avanza hacia el resultado de la investigación que permite exponer los factores que conllevaron a el surgimiento de un Complejo de Seguridad Regional entre Argentina, Brasil y Paraguay para diezmar los efectos del Crimen Organizado Transnacional en la Triple Frontera.

Introduction: Autosomal dominant polycystic kidney disease is the most common hereditary renal disease in humans. Objective: To examine the prevalence, clinical and laboratory characteristics of patients with polycystic kidneys and relate disease manifestations by gender. Methods: This was an observational and retrospective study. All the medical records of patients with polycystic kidneys who initiated hemodialysis between 1995 and 2012, in four centers that treat patients of the coverage area of the 15th regional health Paraná (Brazil), were analyzed. Results: The study included 48 patients with polycystic kidneys, the primary cause of stage 5 CKD. Disease prevalence was one in 10,912 people. The average age of dialysis initiation was 50.7 years and the follow-up time on dialysis until transplantation (36.5 months) was lower among men. Hypertension was the most frequent diagnosis in 73% of patients, predominantly in women (51.4%). The liver cyst was the most frequent extrarenal manifestations in men (60.0%). The death occurred in 10.4% of patients using hemodialysis, and 60% of men. The class of antihypertensive drug used was that acts on the renin-angiotensin system with higher frequency of use among women (53.3%). The post-dialysis urea was significantly higher in men. Conclusion: The prevalence of the disease is low among hemodialysis patients in southern Brazil. The differences observed between genders, with the exception of the post-dialysis urea, were not significant. The findings are different from those reported in North America and Europe.

Back-scattered imaging, X-ray element mapping and electron microprobe analyzer (EMPA) chemical dating reveal complex compositional and age zoning in monazite crystals from different layers and textural positions in a garnet-bearing migmatite in SE Brazil. Y-rich (variable Y(2)O(3), averaging 2.5 wt.%) relict cores are preserved in mesosome and melanosome monazite, and correspond to 793 +/- 6 Ma inherited crystals possibly generated in a previous metamorphic event. These cores are overgrown and widely replaced by two generations of monazite, which are present in all migmatite layers. The first, also Y-rich (average 2.5 wt.% Y(2)O(3)), was produced at similar to 635 Ma during prograde metamorphism under subsolidus conditions, while the second has an Y-poor (<1.5 wt.% Y(2)O(3)), low Th/U signature, and precipitated from low Y and HREE anatectic melts produced by reactions in which garnet was inert. Quartz-rich trondhjemitic leucosome represents lower temperature melt (bearing some subsolidus quartz and garnet with included monazite) formed at temperatures below muscovite breakdown; its Y-poor monazite indicates an age of 617 +/- 6 Ma. Granitic leucosomes formed close to peak metamorphic conditions (T>750 degrees C) above muscovite breakdown have their slightly younger character confirmed by a 609 +/- 7 Ma low-Y monazite age. A similar 606 +/- 5 Ma age was obtained for low-Y monazite rims and domains in mesosome and melanosome, and reflects the time of monazite saturation in interstitial granitic melt that was trapped in these layers. Our results confirm that inherited monazite crystals can be preserved during partial melting at temperatures above muscovite breakdown. Moreover, careful textural control aided by X-ray chemical mapping may allow monazite generated at different stages in a similar to 25 Myr prograde metamorphic path to be identified and dated using an electron microprobe.

A pesquisa visa a examinar as conseqüências da dinâmica de (sub)desenvolvimento econômico espacial brasileiro sobre o grau de disparidades regionais. O trabalho objetiva avaliar se as diferentes intensidades e velocidades das transformações produtivas nos sistemas econômicos regionais levaram a uma situação de maior convergência ou divergência entre os respectivos níveis de desenvolvimento observados na atualidade brasileira. A análise abrangerá um período a partir de meados da década de 80 até o período mais recente, para o qual estão disponíveis as informações estatísticas. A finalidade da análise é verificar também as mudanças setoriais no contexto das realidades econômicas regionais, a partir de vários enfoques, isto é, enquanto geração de produto e absorção de mão-de-obra.
Política cultural do Brasil no exterior e o processo de integração internacional: o caso do Mercosul
Resumo:
Nesta dissertação se propõe a analisar a política cultural do Brasil no exterior e em especial sua participação no processo de criação do Mercosul Cultural. O presente ensaio verifica até que ponto o Brasil conta com uma política cultural no exterior que possa realmente promover difundir e intercambiar a cultura brasileira em âmbito internacional. Buscou-se dentre os vários modelos existentes de política pública marcos teóricos que pudessem servir como parâmetros na análise da política cultural externa brasileira, utilizando-se principalmente as fases de uma política pública e o modelo ótimo normativo de Dror. De maneira geral o autor procurou examinar ao lado da análise da política cultural do Brasil no exterior o processo de integração internacional e a participação do Brasil na globalização enfatizando a cultura como fator fundamental no processo de regionalização promovido atualmente pela Argentina, Brasil, Paraguai e Uruguai.

This doctoral thesis presents an analysis of the production of bicarbonates and related regional development in Brazil. It is widely believed that one of Brazil s vocations lies in the agro-energy sector. However, current national agro-energy policies, together with the experience of Petrobras (the national oil company) in rural settlements in the state of Rio Grande do Norte, show that Brazil has fallen short of effectively including the North and Northeast regions of the country, let alone small-scale rural producers (residing in rural settlements or not), in the development process and related benefits from the country s participation in the current world energy grid. The methodology entails secondary research related to the theme, such as books, official documents, websites and statistical databases from diverse sources, in addition to an analysis of statements from interviews of Petrobras representatives and other important scientific, institutional and labor union authorities, in relation to agro-energy issues and the socio-economic participation of family-based agriculture in this process. Principal findings show a correlation between agro-energy and regional development, creating the potential for numerous opportunities and challenges. Findings demonstrate the possibility of reversing/reducing historically rooted indices of hunger and poverty that continue to devastate the North and Northeast regions. At the same time, the thesis points to a potentially catastrophic increase in regional disparities, should the present historic moment not be seized upon so as to include these regions. Classic examples of non-policy at the federal level are presented as evidence of the absence of a regionally focused agroenergy policy in the current government, reinforced by the experiences of Petrobras in the Rio Grande do Norte rural settlements. Finally, the thesis concludes that there is an urgent need to create a government-sponsored enterprise (with a structure similar to Petrobras) with the purpose of implementing a truly broad and inclusive development process for the bicarbonates production sector, while remaining attentive to Brazil s opportune and critical role in the world s current agro-energy scenario.

O objetivo deste trabalho é analisar a forma como algumas escolas de pensamento, representadas por figuras significativas, percebem no Brasil o tema da integração regional. O foco é a segunda metade do século XX, buscando compreender as concepções de projeção regional e internacional do país, que fundamentam as possibilidades de integração. Para isso, serão discutidos os seguintes temas: o papel do Estado, a visão de país, o nacionalismo, o desenvolvimento econômico e o subdesenvolvimento, o reconhecimento internacional e a percepção dos vizinhos. A ideia da especificidade frente aos países vizinhos é um elemento presente na obra de intelectuais e de formuladores de políticas. Ela se faz presente em muitos países, inclusive em outros dessa região. Buscaremos entender como essa ideia evoluiu no Brasil, chegando, nos anos 1980, à aceitação da existência de uma comunidade de interesses com os países do Cone Sul e da América do Sul.

According to the current international guidelines concerning environmental problems, it is necessary to evaluate and to know the indoor radon levels, specially since most of the natural radiation dose to man comes from radon gas and its progeny. Several countries have established National Institutions and National Programs for the study of radon and its connection with lung cancer risk and public health. The aim of this work is to present the indoor radon measurements and the detection methods used for different regions of Latin America (LA) in countries such as Argentina, Brazil, Ecuador, Mexico, Peru and Venezuela. This study shows that the passive radon devices based on alpha particle nuclear track methodology (NTM) is one of the more generalized methods in LA for long term indoor radon measurements, CR-39, LR-115 and Makrofol being the more commonly used detector materials. The participating institutions and the radon level measurements in the different countries are presented in this contribution. (C) 2001 Elsevier B.V. Ltd. All rights reserved.
