Caio Prado Jr. e o intelectual marxista hoje

This article proposes to engage in dialogue with the work and the trajectory of Caio Prado Júnior, one of the most influential historians and Marxist intellectuals of Brazil. The intention is not to evaluate his production in detail, nor follow the relationships she had with the Brazilian society and the historian’s political options, something already conducted by several researchers. Instead, its intention is to “use” his trajectory and style to freely reflect on some traces of Marxism in Brazil and especially on certain dilemmas inherent in the performance of the Marxist intellectuality. Caio Prado Jr. will, therefore, be treated here as a parameter for a broader reflection on the intellectuals.

Um estudo sobre a relação entre Caio Prado Júnior e Fernando A. Novais

In this paper we propose to analyze the relationship established by Fernando Novais with Caio Prado regarding the studies about the colonization. Putting himself as his disciple, Novais exposes his conception of colonization as a deepening means and a way to overcome the way by which the author of Formação do Brasil contemporâneo understood the colonial phenomenon. This way of putting this relationship has been accepted by both the critics and supporters of Novais, thus acquiring certainty of truth. We show in this paper that by rooting his conception of colonization in Prado’s conception, Novais conceived him in a particular way: as an historian of the ‘sense of colonization’. The analysis of Prado’s concept of colonization shows, however, that this is part of his interpretation of the history of Brazil, as a whole. It follows that we can’t isolate one from the other without disturbing the comprehension of Prado’s conception. The result of our text is thus retaking the Prado’s conception in its historicity.

A crítica alegórica de Grande sertão

Como têm sido publicados, em número crescente, trabalhos baseados na noção/conceito de alegoria sobre a obra rosiana, dos quais alguns têm tido repercussão e visibilidade nos meios acadêmicos – pela seriedade e também pela originalidade com que analisam seu objeto –, examinamos três estudos que tratam a obra de Guimarães Rosa, sobretudo Grande sertão: veredas, como alegoria histórico-política e social do Brasil: de Heloisa Starling, de Willi Bolle e de Luiz Roncari, que, recentemente, sobretudo os dois últimos, publicaram estudos alentados nessa direção. Esses autores têm procurado realizar uma reinterpretação de Grande sertão: veredas a partir da concepção de alegoria, em especial, a de Walter Benjamin, estabelecendo um paralelismo entre o romance rosiano e estudos de historiadores e sociólogos como Oliveira Vianna, Caio Prado Jr., Sérgio Buarque de Holanda, Raimundo Faoro, Gilberto Freyre. Trata-se de leitura que tem raízes, principalmente, nos ensaios de Antonio Candido e de Walnice Nogueira Galvão e que, pelo modo de interpretar a relação realidade/obra de ficção, traz implicações que merecem ser discutidas.

Entre vanguarda e a participação: a democracia no programa político da esquerda brasileira (1930-1935)

This paper examines the conceptions of democracy in the Brazilian left among 1930-1935, in particular those expressed in the manifestos of the National Liberative Alliance (ANL) and the texts written by Luis Carlos Prestes, Virgínio Santa Rosa and Caio Prado Jr. I argue that the Brazilian left started from a common troubled field, according to which land concentration represented the biggest obstacle to genuine political expression of the Brazilian people. Despite the convergence towards land reform, designed as a sine qua non condition to democracy in Brazil, the left has developed two different answers to the practical implementation of the principle of the people's government: the first, which I call altruist vanguard, which is more emphasized on texts of Virgínio Santa Rosa and Luís Carlos Prestes, and the second, the Republican participacionismo, which is explored on the writings of Caio Prado Jr. and ambiguously in the manifests of the National Liberative Alliance.

A questão do Feudalismo no Brasil: um debate político

In this article, we examine the procedure of Brazilian historiography about the debate between Caio Prado Jr. and the Brazilian Communist Party, especially with regard to the relationships of feudal or semi-feudal nature. The historiography put them on opposite sides, considering the intellectual from Sao Paulo from a positive outlook, while the Communist Party is considered from a negative one. However, although distinct, their interpretations of the history of the Brazil make them close in regards to the question of socialism, in that they postpone it to the remote future. Thus, by adopting the procedure of the opposition between both, the historiography fails to consider what really distinguished them.

Carbohydrate metabolism of Xylella fastidiosa: Detection of glycolytic and pentose phosphate pathway enzymes and cloning and expression of the enolase gene

The objective of this work was to assess the functionality of the glycolytic pathways in the bacterium Xylella fastidiosa. To this effect, the enzymes phosphoglucose isomerase, aldolase, glyceraldehyde-3-phosphate dehydrogenase and pyruvate kinase of the glycolytic pathway, and glucose 6-phosphate dehydrogenase of the Entner-Doudoroff pathway were studied, followed by cloning and expression studies of the enolase gene and determination of its activity. These studies showed that X. fastidiosa does not use the glycolytic pathway to metabolize carbohydrates, which explains the increased duplication time of this phytopatogen. Recombinant enolase was expressed as inclusion bodies and solubilized with urea (most efficient extractor), Triton X-100, and TCA. Enolase extracted from X. fastidiosa and from chicken muscle and liver is irreversibly inactivated by urea. The purification of enolase was partial and resulted in a low yield. No enzymatic activity was detected for either recombinant and native enolases, aldolase, and glyceraldehyde-3-phosphate dehydrogenase, suggesting that X. fastidiosa uses the Entner-Doudoroff pathway to produce pyruvate. Evidence is presented supporting the idea that the regulation of genes and the presence of isoforms with regulation patterns might make it difficult to understand the metabolism of carbohydrates in X. fastidiosa.

Search for Wbb(-) and WH production in pp(-) collisions at root s=1.96 TeV

We present a search for Wb (b) over bar production in p (p) over bar collisions at root s=1.96 TeV in events containing one electron, an imbalance in transverse momentum, and two b-tagged jets. Using 174 pb(-1) of integrated luminosity accumulated by the D0 experiment at the Fermilab Tevatron collider, and the standard-model description of such events, we set a 95% C.L. upper limit on Wb (b) over bar production of 6.6 pb for b quarks with transverse momenta p(T)(b)> 20 GeV and b (b) over bar separation in pseudorapidity-azimuth space Delta R-bb> 0.75. Restricting the search to optimized b (b) over bar mass intervals provides upper limits on WH production of 9.0-12.2 pb for Higgs-boson masses of 105-135 GeV.

Search for large extra spatial dimensions in dimuon production with the D0 detector

We present the results of a search for the effects of large extra spatial dimensions in p (p) over bar collisions at root s = 1: 96 TeV in events containing a pair of energetic muons. The data correspond to 246 pb(-1) of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron Collider. Good agreement with the expected background was found, yielding no evidence for large extra dimensions. We set 95% C. L. lower limits on the fundamental Planck scale between 0.85 and 1.27 TeV within several formalisms. These are the most stringent limits achieved in the dimuon channel to date.

Study Z gamma events and limits on anomalous ZZ gamma and Z gamma gamma couplings in pp(-) collisions at root s=1.96 Tev

We present a measurement of the Z gamma production cross section and limits on anomalous ZZ gamma and Z gamma gamma couplings for form-factor scales of Lambda=750 and 1000 GeV. The measurement is based on 138 (152) candidates in the ee gamma (mu mu gamma) final state using 320(290) pb(-1) of p (p) over bar collisions at root s=1.96 TeV. The 95% C.L. limits on real and imaginary parts of individual anomalous couplings are vertical bar h(10,30)(Z)vertical bar < 0.23, vertical bar h(20,40)(Z)vertical bar < 0.020, vertical bar h(10,30)(gamma)vertical bar < 0.23, and vertical bar h(20,40)(gamma)vertical bar < 0.019 for Lambda=1000 GeV.

Measurement of the lifetime difference in the B-s(0) system

We present a study of the decay B-s(0)-> J/psi phi. We obtain the CP-odd fraction in the final state at time zero R-perpendicular to = 0.16 +/- 0.10 (stat) +/- 0.02(syst), the average lifetime of the (B-s(0), (B) over bar (0)(s)) system, (tau) over bar (B-s(0)) = 1.39(-0.16)(+0.13)(stat)(-0.02)(+0.01)(syst) ps, and the relative width difference between the heavy and light mass eigen-states, Delta Gamma/(Gamma) over bar = (Gamma(L) - Gamma(H))/(Gamma) over bar = 0.24(-0.38)(+0.28)(stat)(-0.04)(+0.03)(syst). With the additional constraint from the world average of the B-s(0) lifetime measurements using semileptonic decays, we find (tau) over bar (B-s(0)) = 1.39 +/- 0.06 ps and Delta Gamma/(Gamma) over bar = 0.25(-0.15)(+0.14). For the ratio of the B-s(0) and B-0 lifetimes we obtain (tau) over bar (B-s(0))/tau(B-s(0)) = 0.91 +/- 0.09(stat) +/- 0.003(syst).
