Nascimento, Wellington Ferreira do;Silva, Edson Ferreira da;Veasey, Elizabeth Ann;
Scientia Agricola , 2011, DOI: 10.1590/S0103-90162011000600008
Abstract: the agro-morphological characterization is fundamental in order to provide information for plant breeding programs. the aim of the present study was to characterize 146 accessions of upland rice (oryza sativa l.), based on qualitative and quantitative agro-morphological descriptors. the experiment was conducted in recife, state of pernambuco, brazil, using a randomized block design with three replicates. polymorphism was observed among 12 of 14 qualitative characters evaluated, whereas significant differences (p < 0.05) were observed for 11 of the 14 analysed quantitative traits. genetic variance was higher than environmental variance and the average inheritability coefficients were above 80 % for all characters, which ensures the predominance of the genetic components in the differences observed among accessions. on the cluster analysis for qualitative traits the accessions were classified in two groups with a total of 18 duplicates, whereas for the quantitative traits three groups were obtained with few subgroups. the principal component analysis for quantitative traits showed great dispersion of the accessions. the most divergent group of accessions included the genotypes mitsukasane, mie, tomoe mochi, ooba kirishima and nourin mochi 6, which showed a higher number of spicklets per plant. there is high variability among the rice accessions from the germplasm collection studied, which presents great importance for breeding programs or for genetic studies on this species.

Abstract: Esse artigo espera contribuir para a compreens o da rela o entre a religi o e a política. Por meio da análise tipológica e do recurso metodológico da história oral temática elaboramos o seu ambiente teórico. Estudamos os jovens inseridos na Pastoral da Juventude do Meio Popular entre meados das décadas de 1980 e 1990, na regi o industrial de Belo Horizonte – Brasil. Estes jovens s o representantes do grande movimento religioso conhecido como cristianismo da liberta o de larga e profunda repercuss o na história política e religiosa da república brasileira da segunda metade do século XX. Nossa compreens o situa-se na passagem do catolicismo tradicional para o catolicismo internalizado experimentado por esses jovens e suas famílias no processo de migra o das áreas rurais para a jovem área urbana. Vale dizer que os fragmentos de entrevistas citadas foram realizadas por nós para a pesquisa que deu vaga a esse artigo. Palavras-chaves: Juventude. Religi o e política. Esquerda católica brasileira. Catolicismo Abstract This article aims to contribute to the understanding of the relationship between religion and politics. The theoretical environment of this research has been prepared by analyzing typological and methodological resource of oral history. For this purpose, we studied the young participants of the Youth Ministry of the "lower middle class" between the mid 1980s and 1990 in the industrial region of Belo Horizonte - Brazil. These young people represent a religious movement known as liberation Christianity, with profound repercussions in the political and religious history of the Brazilian republic of the second half of the twentieth century. The scope of this study lies in the transition from traditional Catholicism to the form of Catholicism internalized and experienced by these young people and their families in the process of migration from rural to urban areas.

Abstract: Introduction: The technical and scientific evolution is the greatest advance in dentistry since its regulation with the law 5.081/1966; however it is worth remembering that constant modernization of treatments brings along a proportional increase on the dentist’s responsibilities with his patient. The professional should always keep in mind that along with his hand ability, innovative techniques and the best material applied there is Deontology evaluating three areas: civil, ethical-administrative and criminal. It is the dentist’s obligation to follow and respect the deontological issue in a world where lawsuits against peers have increased exponentially. Objective and Conclusion: The presented study reports the relations in the Brazilian penal code concerning to criminal responsibility of the health professionals, analyzing the dental behaviors which, once applied, configure criminal types, subjecting the agent to the prosecution and trial of criminal justice. A little known subject hardly ever discussed in dentistry.

Abstract: This article aims at describing the semantic argumentative structure of the textual/discursive genre Letter of Declaration, one of the documents with which the executive secretary frequently deals. This investigation is based on the Argumention Theory in the Language proposed by Ducrot (1988,1987). We also used the studies about Discursive Modalization proposed by Koch (2002), Castilho e Castilho (1993), Nascimento (2005), among others. Modalization is considered here as a semantic argumentative strategy, as it enables the speaker to make a statement or to express a point of view about the content of his/her enunciation, according to the interlocution. This study about the previously mentioned gender is qualitative, quantitative and descriptive. The corpus used is composed of 20 (twenty) Letters of Declaration issued by different organizations or private and public institutions. We perceived that in the Letters of Declaration analysed argumentation is achieved by the use of modalizers and argumentative operators, used by the speaker to produce different effects of meaning in the texts. Este artigo tem como objetivo descrever a estrutura semantico-argumentativa do gênero textual/discursivo declara o, um dos documentos com o qual o profissional de Secretariado lida frequentemente. Essa investiga o tem como base a Teoria da Argumenta o na Língua, proposta por Ducrot (1988, 1987). Utilizamos também os estudos de Modaliza o Discursiva, proposta por Koch (2002), Castilho e Castilho (1993), Nascimento (2005), entre outros. A modaliza o é aqui considerada como uma estratégia semantico-argumentativa, uma vez que permite ao locutor imprimir uma avalia o ou ponto de vista sobre o conteúdo de seu enunciado, em fun o da interlocu o. A investiga o realizada a respeito do referido gênero é de natureza qualitativa e quantitativa, de cunho descritivo, e o corpus utilizado é constituído por 20 (vinte) declara es emitidas por diferentes organiza es ou institui es públicas e privadas. Nas declara es analisadas percebemos que a argumenta o se faz presente através dos modalizadores e operadores argumentativos, utilizados pelo locutor para imprimir diferentes efeitos de sentido nos textos.

Revista Nordestina de Ecoturismo , 2011, DOI: 10.6008/ess1983-8344.2011.002.0003
Abstract: O uso de territórios com paisagens naturais para implanta o de atrativos turísticos n o é recente, marcando a cria o e implementa o legal das Unidades de Conserva o (UCs), os Parques Nacionais. O Brasil segue essa tendência, onde territórios de várias UCs, detentores de beleza cênica, s o usados como atrativo turístico. O Sistema Nacional de Unidades de Conserva o, responsável pela cria o, gest o e implementa o de UCs, divide-as no grupo de Prote o Integral e de Uso Sustentável. Esse ensaio tem como recorte empírico a APA do Morro do Urubu, em Aracaju/SE, que disp e de paisagens naturais usadas como atrativo turístico. Como objetivo analisar a instala o de atrativos turísticos na APA, e a conserva o socioambiental desse remanescente florestal. A pesquisa foi realizada mediante: análise bibliográfica e documental; entrevista semi-estruturada: responsável pela administra o, e coordenador técnico da APA (SEMARH); técnico responsável pelo gerenciamento do Parque da Cidade (EMDAGRO); comandante do Pelot o Ambiental; pesquisa de campo para identifica o dos atrativos turísticos, análise dos impactos socioambientais no espa o interno e no entorno. Além dos benefícios ambientais oferecidos gratuitamente, é usada para visita o pública, em fun o dos atrativos turísticos: Zoológico, Mirante da Santa, Teleférico, e das áreas para lazer e recrea o. A apropria o do território para a demanda das atividades turísticas contribui para a dilapida o dos recursos naturais e para a exclus o social daqueles que mantém la os afetivos com a APA. Assim, tal atividade concorre com os propósitos maiores da conserva o socioambiental, recriando lugares e excluindo as comunidades locais do cotidiano. Contudo, para a conserva o dos servi os ambientais da APA é necessário criar instrumentos de gest o ambiental, visando o ordenamento territorial; realiza o de campanhas educativas para visitantes e comunidade local; repasse dos lucros das empresas terceirizadas que usam o território da APA; e cobran a de taxas de entrada para visitantes.

Abstract: the area of study is located in the atlantic equatorial margin shelf offshore ceará state (brazil), being originated during the formation of equatorial atlantic (aptian). the residual gravity data highlight offshore continental framework structures, specially the transbrasiliano lineament and its offshore portion (transversal lineament). the continental margin basins (ceará and offshore potiguar) were also highlighted. the relief anomaly map shows that the superficial features are controlled by ne-sw precambrian structures, mainly in the segment offshore acaraú. in the outer shelf offshore camocim, this control is due to both nw-se and e-w features, probably related to transform tectonics in the piauí-camocim sub-basin. e-w trends, possibly related to oceanic fractures, and nw-se trends, probably related to precambrian structures, are characteristic of the central sector. the southeastern sector presents shelf sub parallel trends that approach contact between shallow basement and the offshore potiguar basin. the neotectonic stress state is inferred as wrench-type with maximum horizontal stress sub parallel to the margin trend (mainly acting in the inner shelf) and extensional with minimum horizontal stress sub orthogonal to the margin trend (mainly in the outer shelf).
