Observations anatomiques concernant la valve atrioventricuiaire gauche humaine

30 hearts of male and female, white and non-white Brazilians of different ages were studied. The leaflets of the left atrioventricular valves were removed near the fibrous ring and anatomically studied under chirurgical microscope. The authors observed: the leaflet's shape, the presence of commissures, the implantation manner of the chordae tendineae and the distribution on the leaflets. Special attention was concentrated on the terminology used by different authors for the structures of the 'mitral complex'.

Les enquêtes militaires et l-organisation des intellectuels de gauche au Brésil dans les années 1960

This article has as its object of analysis the Inquiries Police-Military, adocumentation produced during the military dictatorship in Brazil (1964-1985)and today it’s important sources for historians, sociologists, political scientists to understand the internal dynamics of repression, as well as specifying certainnetworks communist militancy and the engagement of progressive sectorsagainst the military government. Documents, court proceedings that currently in Brazil endorse the work of the Truth Commission, which seeks to ascertain the fate of disappeared politicians and determine the actions of the organs of repression during the military dictatorship in Brazil.

Rosa Luxemburg: revolução e democracia

Y aurait-il un lien indissoluble entre révolution et terreur? de nos jours, une partie de ce qui a été autrefois la gauche y croit Contre l'idée de révolution, saisie corne la source du totalitarisme, on propose le renforcement de la démocratie. Cet article a l'intention de contribuer à ce débat en montrant l'alternative révolutionnaire et démocratique présentée par Rosa Luxemburg. Pour elle la démocratie n'est pas une valeur universelle abstraite mais justement le résultat d'un processus révolutionnaire où les masses prolétariennes, agissant dans la plus large liberté, lancent les fondements d'une nouvelle époque. Néanmoins la révolution allemande où Rosa Luxemburg et Karl Liebknecht ont eu un rôle de premier plan avorte et ils sont assassinés. Cette défaite trace, d'une certaine manière, le destin de l'Allemagne contemporaine.

Eleições, política externa e integração regional

L'article examine le rapport entre les régimes politiques domestiques et l'intégration régionale. L'argument central montre que la thèse selon laquelle une convergence politique plus profonde avec les autres régimes de gauche de la région favoriserait encore plus l'intégration sud-américaine recèle un paradoxe qui n'a pas encore été traité dans les débats. Bien qu'il soit acceptable l'idée qui préconise que des gouvernements de gauche ont tendance à donner leur appui politique au régionalisme sud-américain, il est tout aussi vrai l'idée selon laquelle les régimes présidentiels de gauche sont moins favorables à la transnationalisation des normes et à la cession de souveraineté aux instances transnationales. L'article présente brièvement la révision de la littérature à propos de la relation entre politique interne (régimes politiques et des partis) et production de la politique externe et, au long de ce débat, il analyse le thème des accords commerciaux dans les élections sud-américaines, y compris le cas brésilien.

Self-Structuring of Lamellar Bridged Silsesquioxanes with Long Side Spacers

Diurea cross-linked bridged silsesquioxanes (BSs) C(10)C(11)C(10) derived from organosilane precursors, including decylene chains as side spacers and alkylene chains with variable length as central spacers (EtO)(3)Si- (CH(2))(10)-Y(CH(2))(n)-Y-(CH(2))(10)-Si(OEt)(3) (n = 7, 9-12; Y = urea group and Et = ethyl), have been synthesized through the combination of self-directed assembly and an acid-catalyzed sol gel route involving the addition of dimethylsulfoxide (DMSO) and a large excess of water. This new family of hybrids has enabled us to conclude that the length of the side spacers plays a unique role in the structuring of alkylene-based BSs, although their morphology remains unaffected. All the samples adopt a lamellar structure. While the alkylene chains are totally disordered in the case of the C(10)C(7)C(10) sample, a variable proportion of all-trans and gauche conformers exists in the materials with longer central spacers. The highest degree of structuring occurs for n = 9. The inclusion of decylene instead of propylene chains as side spacers leads to the formation of a stronger hydrogen-bonded urea-urea array as evidenced by two dimensional correlation Fourier transform infrared spectroscopic analysis. The emission spectra and emission quantum yields of the C(10)C(n)C(10) Cm materials are similar to those reported for diurea cross-linked alkylene-based BSs incorporating propylene chains as side spacers and prepared under different experimental conditions. The emission of the C(10)C(n)C(10) hybrids is ascribed to the overlap of two distinct components that occur within the urea cross-linkages and within the siliceous nanodomains. Time-resolved photoluminescence spectroscopy has provided evidence that the average distance between the siliceous domains and the urea cross-links is similar in the C(10)C(n)C(10) BSs and in oxyethylene-based hybrid analogues incorporating propylene chains as side spacers (diureasils), an indication that the longer side chains in the former materials adopt gauche conformations. It has also allowed us to demonstrate for the first time that the emission features of the urea-related component of the emission of alkylene-based BSs depend critically on the length of the side spacers.

O Comando dos Trabalhadores Intelectuais e a formação das esquerdas culturais na década de 1960

The Comando dos Trabalhadores Intelectuais (CTI) was a group, a space of organization and representation of brazilian intellectuals and artists and that, previous to the military coup in 1964, participated of the debates and fomented the inclusion of sectors of the national intelligentzia in the democratization’s process of the culture. His insertion politics, of the point of view of the effervecence lived for the organized socials movements in Brazil in the years of João Goulart’s government, bring elements to detail the dynamics of the cultural left’s organizations that had emerged of the review’s process of Brazilian Communist Party (PCB), since 1958. The relevance of CTI is confirmed when understand it like an organization that congregated many intellectuals and artists that, after of the military coup in 1964, had been presents in the artistic and cultural brazilian scene, doing resistance to the military governments that if had occurred in the next decades.

A revista civilização brasileira: projeto editorial e resistência cultural (1965-1968)

During the first years of the military dictatorship, established in Brazil through a coup d'État, a number of institutions which repression had left unarticulated began a process of resistance and opposition to the military government. Cultural resistance was one of the consecrated forms of resistance that was exercised by intellectuals, artists, professors and cultural producers, among others, and that became an unprecedented political and cultural phenomenon in the country's history. Political, insofar as it aided in the process of re-organizing left-wing political parties and in the revision of the ideological postulates of its preeminent party, the PCB (Partido Comunista Brasileiro - Brazilian Communist Party). Cultural, because this re-organization occurred, frequently, within the ambit of cultural productions, in which the left created a space for contestation and engagement through the arts and intellectual activities. Within this process, between the years 1965 and 1968. The journal Civilização Brasileira became an important space for the building of leftist cultural resistance against the military dictatorship. The journal was able to impose its political legitimacy while at the same time participating actively in a market o cultural goods sustained by the so-called cultural hegemony of the left.

Reproducibility of heart rate and rating of perceived exertion values obtained from different incremental treadmill tests

Objective The present study aimed to examine the reproducibility of heart rate (HR) and rating of perceived exertion (RPE) values obtained during different incremental treadmill tests. Equipment and methods Twenty male, recreational, endurance-trained runners (10-km running pace: 10–15 km·h−1) performed, in a counterbalanced order, three continuous incremental exercise tests with different speed increments (0.5 km·h−1, 1 km·h−1 and 2 km·h−1). Thereafter, each participant performed the three tests again, maintaining the same order as before. The reproducibility of the HR and RPE values were analyzed for all protocols during submaximal intensities (8, 10, 12, and 14 km·h−1). In addition, it was examined the reproducibility of maximal HR (HRmax) and peak RPE (RPEpeak). Results The variability of both the HR and RPE values showed a tendency to decrease over the stages during the incremental test and was not or slightly influenced by the incremental test design. The HR at 14 km·h−1 and HRmax presented the highest reproducibility (CV < 2%). In contrast, the submaximal RPE values showed higher variability indices (i.e., CV > 5.0%). In conclusion, the HR values were highly reproducible during the stages of the incremental test, in contrast to the RPE values that presented limited reproducibility.
