A História entre Tempos e Contratempos: Fontes Ibiapina e a obscura invenção do Piauí

Dans ce texte, nous prenons avec probleme le départment bresilien de Piauí comme espacialité de la Région « Nordeste », suivant les instants de son insertion politique et discursif dans l'identité régionale, qui s'est donnée entre la fin des années 1950 et débuts des années 1970. Pour ceci, nous proposons une analyse de discours identitaires de Piauí comme la littérature et le folklore produits alors, cherchant à rapporter telles discours avec les pratiques et intérêts politiques qui ont concouru pour la « nordestinization » de Piauí. Parmi ces discours et dans dialogue avec eux, nous prenons centralement l'oeuvre du juge et ecrivain João Nonon de Moura Fontes Ibiapina, emisseur de signes qui apparaît en ce moment. Notre objectif est discuter les images élaborées sur Piauí et son inclusion dans les stéréotypes cristallisés de Nordeste, comme la pauvreté et la nécessité, la vie dans le champs et la prédominance d'une « culture populaire » régionale. Dans une période d'importantes mutations dans la société brésilienne, dans la production culturelle, dans heurtes régionalistes Nordeste et dans les formes de penser et pratiquer les espaces, les intellectuels de Piauí que nous étudions ont essayé de recouvrir de mots et de sens la noirceur et l'incommode silence concernant le Piauí dans la Nation bresilienne, quand le déparment s'intégrait, au moyen de la Région, au Brésil urbain et industrialisé

Clarissimo speculo bonitatis Dei : o mundo de Tomás de Celano e a sua leitura de mundus

The aim of this study is to understand the version of St. Francis of Assisi created by Friar Thomas of Celano in his hagiographic works. That study also it examines how the Order of Friars Minor and the Papacy have understood the relationship between Christians and the world and turned thisunderstanding in a version of the Saint. Factors such as the replacement of Neoplatonism byAristotelianism as philosophical paradigm and economic and social changes have contributed to change the interpretation of the biblical mandate to not love the world , no longer interpreted as materiality, but as an order for Christians to flee sin. The rejection of the world was replaced by a greater appreciation of nature and society. Moreover, increasingly, the body went from enemy to friend, becoming the brotherbody. Such analysis is important to review the idea, so common in the historiography of what MaxWeber called Worldly Asceticism, the Christian life lived in society, only emerged in Protestantism in opposition to monasticism. The mendicant orders, especially the minority tried during the thirteenth century, the period of analysis of this work, experience the loving nature of Christianity and acting,through preaching and charity in the cities.To make this work, were analyzed the hagiographic discourse (on San Francisco) made by Thomas of Celano, Vita beati Francisci (called Vita Prima) and Memorial in desideiro anime (named Vita Secunda) and, from this, understand the Celano´s interpretation on how it should be the Christian's relationship with the world. The world ceased to be adistorted reflection of a perfect reality, becoming the perfect reflection of God's goodness.

Mundo de medo: inquisição e cristãos-novos nos espaços coloniais capitanias de Pernambuco, Itamaracá e Paraíba (1593-1595)

Founded in 1536, the Court of the Holy Office of the Portuguese Inquisition was established as an ecclesiastical institution, but at the same time subordinate to the real powers. Among the main victims of persecution effected by the Holy Office, were the New Christians - Jews forcibly converted in 1497 or their descendants - that due to their socio-religious were repeatedly accused of heresy. This paper conducted a survey that sought to understand the historical performance of the Inquisition in Brazil in the sixteenth century on the New Christians, especially those accused of secretly retaining the religious customs of the Mosaic law, given the investigative and punitive procedures employed by the Inquisition as part of a set of actions that produce social insecurities and producers / broadcasters of fear in the populations under scrutiny. In this sense, the approach was based on the analysis of documents produced on the first visit of inspection performed in Brazil inquisitorial sixteenth century, concerning the captaincy of Pernambuco and Paraiba Itamaracá (1593-1595), not excluding, however, the sources of the first stage of visitation that occurred between 1591-1593 in the province of Bahia de Todos os Santos, even though its use is ancillary and punctual. The objective of this research was to understand the consequences of inquisitorial procedures generated on the imaginary, and the Inquisition, using the expressions and signs of fears relating to individuals contained in the New Christian complaints to the Holy Office as documentary evidence of the fear caused by the Holy Tribunal. The adoption of specific behaviors by the New Christians in the home - these spaces are appropriate and adapted to the detriment of the religious practices of Judaism features - characterizes the spatial perspective of the study, thus indicating a further objective of the study: to understand how the New Christians experienced domestic spaces in a historical context marked by behavioral surveillance generally considered morally condemned and suspected of heresy. The research was conducted to analyze the complaints and quantitative survey of some indices of documentation for the understanding of overall charges and how individuals New Christians were concerned with the domestic space, using them to maintain criptojudaica religiosity, transformed places housing often esnogas, makeshift synagogue for meetings and celebrations of Judaizing New Christians. The formulations of Michel de Certeau on appropriations and meanings of space - presented by the author in the metaphor of "practice areas" - were integrated into the workforce in order to understand the ways in which the New Christians appropriated the colonial houses, designed these spaces a very specific language in the Crypto, in which women are prominent figures. The works of Jean Delumeau and Bartholomé Benassar integrate the discussion of the Inquisition and the sensibilities of fear in the work performed. The analysis allowed the documentation to understand the meaning and the extent related to the general fear that the Inquisition represented. Some complaints are indicative of fears that can be perceived implicitly based on behaviors and attitudes adopted by the New Christians, others, however, are direct expressions of fear caused by allusion or initiative of the actions of the Inquisition in colonial Brazil in the sixteenth century

A capitania de São José do Piauhy na racionalidade espacial Pombalina (1750-1777)

Em meio às intervenções políticas, econômicas e administrativas realizadas no Brasil a partir de 1750, é possível observar como se deram as tentativas de organização da capitania de São José do Piauhy e até mesmo o seu reconhecimento como importante área pecuarista da colônia. Neste trabalho, realizou-se um recorte espacial priorizando a região em que a apropriação territorial teria se dado de forma mais diversa em tal capitania, pois além dos procedimentos de aquisição de sesmarias, existiram ainda os processos de herança e confisco. Sobre estes últimos, os mesmos incidiram sobre as fazendas que pertenceram ao sertanista baiano Domingos Afonso Mafrense, e que após serem deixadas de herança para os religiosos da Companhia de Jesus (1711), foram confiscadas pela Coroa Portuguesa (1759). Isso aconteceu em meio ao planejamento e execução de medidas governamentais que atingiram todos os domínios portugueses durante esse período, a chamada Política Pombalina. Tais intervenções administrativas, por sua vez, puderam ser analisadas tomando-se como referência a confecção da primeira representação cartográfica destinada a tal capitania, o Mappa Geográfico da Capitania do Piauhy, produzido pelo engenheiro italiano Henrique Antônio Galúcio. Deste modo, considerando-se as particularidades da política portuguesa destinada ao interior do Brasil, em meados do séc. XVIII, com destaque para as medidas incidentes sobre os modos de vida indígena e rural, observou-se a tentativa de implantar-se uma nova forma de organização espacial, a partir de modos e instalações urbanas. Neste contexto, São José do Piauhy passa a ser alvo de intensas investidas enquanto área oficialmente pertencente ao Estado do Grão-Pará e Maranhão

Avaliação energética da produção de etanol utilizando como matéria-prima a cana-de-açúcar

This research analyzed the energetic consumption of the etanol, using as raw-material sugar cane. The searches were carried out from the field in the Midle Paranapanema River Region, São Paulo state, in the period from January to December 2007. The referring energy consumption from the crop production phase and industrial processing were evaluated. It was verified that the total energetic cost of the crop production corresponded to 14370.9MJ ha(-1), and the most onerous item was the inputs (50.4%). In the industrial step, the energetic consumption was equivalent to 1,641.56MJ t(-1), The 'hydrolysis, saccharification and broth treatment operations' represented 71.72% of the total energetic expenditure. It was also observed an energetic cost of 2.0MJ L(-1) in relation to the etanol produced in the main crop production operations, and 19.4MJ L(-1) in the industrial processing. The energy efficiency observed in the crop production and industrialization were of 1.1.

Avaliação da expressão da BMP -2/4 e BMPR-IA em Carcinoma Epidermóide Oral metastático e não metastático

The expression of bone morphogenetic proteins (BMPs) is altered in a variety of human canceres. The BMP-2/4 and BMPR-IA were recently shown to be overexpressed in high-risk premalignant and malignant lesions of oral epithelium. The present study analysed the expression of BMP-2/4 and BMPR-IA in Oral Squamous Cell Carcinoma (OSCC) such as their implications in disease prognostic using munohistochemistry. Ten cases of Oral Fibroepithelial Hiperplasia were selected as a control group. The experimental group included 16 cases of OSCC without metastases and 7 cases of OSCC metastatic. The presence or absence of nodal metastases was used as parameter to evaluated the disease prognostic. The results demonstrated weak immunoreactivity for BMP-2/4 and BMPR-IA in every case of the control group. In the cases of OSCC with metastases an overexpression of BMP-2/4 (71,4%) was observed while the BMPR-IA showed weak expression (85,7%). In the cases of OSCC without metastases BMP-2/4 (62,5%) and BMPR-IA showed strong immunostaining standing out an overexpression of the receptor in all the specimens. Observed statistical significance for correlation between the oral cancer prognostic and the staining intensity of the BMP-2/4 (p=0,002). There wasn t statistical significance for association between the staining intensity of the BMPR-IA and the disease prognostic (p<0,001). In conclusion, this findings suggest that the overexpression of BMP-2/4 associated with the loss of expression of the BMPR-IA in OSCC metastatic has prognostic relevance, as the loss of sensitivity to BMPs can be an indicative of metastases development in OSCC

Respostas morfogênicas e estruturais de gramíneas tropicais em regime de corte no nordeste brasileiro

The production of forage grasses is directly related to the morphogenesis. The knowledge of the morphogenetic and structural variables of forage plants is important for determining appropriate conditions of grazing livestock to ensure efficient and sustainable. Thus the objective of this study was to evaluate morphogenetic and structural responses of three genera of grasses, Brachiaria, Panicum and Cenchrus in a cutting regime. The experimental design was randomized blocks with three replications and six treatments. After each section were evaluated for forage production, appearance and elongation rates of leaves and stem, phyllochron, final leaf length, number of living leaves, leaf lifespan, leaf senescence rate, tiller density and tiller dynamics. On forage yield the highest values were obtained in cultivars Xaraes, Piata and Massai. The tiller density was higher for cv Massai. It is concluded that the cultivars of Panicum and Brachiaria had a higher tillering dynamics in increasing the turnover rate of tissues that are indicators of forage production, assuming that the cultivars of these genera are predisposed to use forage in the Northeast

Exames parasitológicos, imunoistoquímicos e histopatológicos para detecção de Leishmania chagasi em tecidos esplênicos de cães com leishmaniose visceral

O propósito do presente trabalho foi o estudo da Leishmaniose Visceral Canina - LVC por meio de métodos parasitológicos e imunoistoquímicos para a detecção de formas amastigotas de Leishmania (L.) chagasi em baço, além de descrever a histopatologia das lesões esplênicas em 34 cães, com diferentes manifestações clínicas da LVC, eutanasiados pelo Centro de Controle de Zoonoses de Ilha Solteira, SP. Esses animais foram examinados clinicamente antes da eutánásia e de acordo com os sinais clínicos da LVC, foram classificados em três grupos: assintomáticos (8 cães), oligossintomáticos (17 cães) e sintomáticos (9 cães). Após a realização desses exames, dos 34 cães, 22 (64,7%) estavam positivos e 12 (35,3%) negativos. Desses cães positivos, 1/22 (4,5%) era assintomático, 12/22 (54,5%) eram oligossintomáticos e 9/22 (40,1%) sintomáticos. Pela histopatologia, os cães, especialmente os sintomáticos apresentavam o baço com inflamação crônica e espessamento na região capsular e trabecular, além de extensa alteração morfológica na polpa vermelha e branca pela presença de grande quantidade de macrófagos repletos de amastigotas, pela reação granulomatosa inflamatória e pelas áreas hemorrágicas. Os exames histopatológicos e a detecção microscópica direta da L. (L.) chagasi revelaram que o baço é um órgão útil para auxiliar no diagnóstico da LVC. A coloração imunoistoquímica foi a que detectou o maior número de tecidos esplênicos positivos com amastigotas, além de elucidar os casos suspeitos pelos exames parasitológicos, principalmente, nos animais assintomáticos ou oligossintomáticos.
