Caracterização fitoquímica e ensaios biológicos de Coleus blumei Benth

Coleus blumei Benth (Lamiaceae), popularly known in Brazil as heart-hurt or coleus-of-Java is an ornamental plant widely used due to the color of its leaves. Several species of the genus Coleus present compounds with antioxidant, antimicrobial and allopathic activities due to the presence of chemicals such coleonol, forskolin and rosmarinic acid. Therefore, this study aimed to carry out phytochemical study and biological tests to evaluate the antibacterial, antioxidant and allopathic activities of the 70% ethanol extract and its fractions ethyl acetate, dichloromethane and end aqueous fraction leaf of Coleus blumei Benth. The plant extract was prepared by turbolisis from the powder of dried leaves, as a solvent for extraction using 70% ethanol. The ethanol extract was fractionated with solvents dichloromethane and ethyl acetate. The phytochemical study identified the presence of saponins, free anthraquinones, flavonoids and anthocyanidins. In evaluating the antibacterial dichloromethane fraction showed activity against all microorganisms tested both in agar diffusion test and microdilution test. The 70% ethanol extract showed activity against the micro-organisms S. aureus and S. epidermidis in agar diffusion test and against all microorganisms tested in microdilution test. The ethyl acetate fraction showed activity against the micro-organism S. aureus in the agar diffusion test and against all microorganisms tested in microdilution test. The end aqueous fraction showed no activity against any micro-organism tested. In the test of evaluation activity allopathic dichloromethane fraction showed greater inhibition of seed germination and growth of tomato (Lycopersicon esculentum Mill), followed by 70% ethanolic extract, the ethyl acetate fraction and the end aqueous fraction. In testing the antioxidant activity with DPPH ethyl acetate fraction showed higher antioxidant activity followed... (Complete abstract click electronic access below)

Análise da influência da concentração de feixeis de fibras de bambu em ensaios de piso

Bamboo has one of the highest growth rates among plants, however, its lignifications (which confers resistance) takes around a few years and, therefore, certain physical characteristics and mechanical, that depend on this process will only be acquired between the three to six years old. In addition, bamboo also has significant density variations in different parts of the stem, both in the radial direction as the axial. In particular the radial direction, where the density found in the inner and outer (near the bark) of a single stem can range on average from 0.5 to 0.9 g/cm3. Thus, the application of bamboo as a floor, there to examine whether both sides of the bamboo (internal and external), provide resistance properties required for that purpose. In this study sought to characterize and quantify the influence of the concentration of fiber bundles in the inner and outer sides of rules or bamboo strips of bamboo flooring through testing service. Analyses performed were based on ASTM D 2394- 83 for wooden floors and derivatives. This was necessary because of the absence of a specific prohibition of the use and testing of floors made of bamboo and its products. The data were analyzed by ball indentation test shooting, test for resistance to abrasion, indentation test for stress / load treadmill test and by indentation loads applied to small areas - test the jump. The results of the tests were extremely friendly bamboo, even this presents considerable differences between the resistances obtained from assay of the cover of the inner and outer face, being comparable with those of many commonly used to manufacture wood flooring. This comparison was made possible by information from technical trials of several floors made with wood

Ensaios de mutação gênica reversa e teste do micronúcleo para avaliação da atividade mutagênica de Pouteria torta E Pouteria ramiflora

O Brasil é um país dotado de Biodiversidade incomparável da qual advém inúmeras plantas medicinais que são frequentemente utilizadas de acordo com conhecimento empírico da população em geral. Considerando a importância de investigar os efeitos farmacológicos e toxicológicos de espécies vegetais utilizadas com fins terapêuticos, foi objetivo do presente trabalho avaliar a atividade mutagênica dos extratos metanólicos e hexânicos de Pouteria ramiflora e Pouteria torta, pois seus dados farmacológicos descritos na literatura são bastante restritos, destacando-se as atividades antimicrobiana, citotóxica e imunomoduladora. Como ferramenta foram escolhidos os testes de Ames e do Micronúcleo, pois ambos são preconizados pela ANVISA em testes de toxicidade de fitoterápicos. No Teste de Ames foram utilizadas as linhagens TA100, TA98, TA97a e TA102 de Salmonella typhimurium em presença e ausência de metabolização e no ensaio do micronúcleo foi utilizado o sangue periférico de camundongos Swiss tratados in vivo. Os resultados constataram que os extratos de ambas as espécies provocaram desvios da normalidade, ou seja, o Teste de Ames detectou aumento no número de revertentes por placa e o Teste do micronúcleo mostrou aumento significativo no número de células micronucleadas. Esses resultados demonstraram claramente que as duas espécies de Pouteria estudadas apresentaram potencial mutagênico e, portanto, o uso popular dessas plantas deve ser feito com cautela

Relações Públicas nas agências de comunicação: uma análise dos discursos dos mercados

Public Relations is an area of communication that has many definitions given by both professional associations and by many authors. Academic and professional discussions on a precise definition of the area are recurrent. Considering this issue, it was decided to study the relationship between public relations and communications agencies, assuming that this is a market segment that includes the public relations. This paper analyzes the discourses of communication agencies and how the Public Relations are handled by them. For this, it was used theories about the history of public relations as well as definitions and concepts of its main authors. Furthermore, we present the characteristics of communication agencies, the contexts associated with its emergence in Brazil and the future prospects of this market segment in the opinion of the professionals who work in it. The study about the discourses of communications agencies was based on French Discourse Analysis, using books from important authors of the area, such as José Fiorin and Helna Brandão. The discourses analyzed were those present on websites of three communications agencies in the state of Sao Paulo. It was noted that not always the participation of public relations in communication agencies is highlighted, although the services of these agencies are based on techniques and typical functions of Public Relations. Above all, what the discourses are seeking to highlight are the experience and expertise in organizational communication owned by its staff

Ensaios ecotoxicológicos da biodegradação de óleos

O presente trabalho teve como objetivo estudar a biodegradação de efluente oleosos em ambiente terrestre. Foram avaliados os potenciais degradação dos seguintes óleos: óleo lubrificante automotivo usado, óleo vegetal novo e usado, e biodiesel. Os ensaios realizados objetivaram, pelo método de respirometria, quantificar e comparar as porcentagens de biodegradação medida através da formação do CO2 da respirometria bacteriana entre amostras de solos contaminados por diferentes tipos de óleo. Além destes ensaios, foram realizados testes colorimétricos que, indicarão, pela mudança de cor do indicador, quais os óleos levam mais tempo para serem completamente degradados. Dessa maneira, foi possível verificar a degradabilidade relativa dos óleos, e contribuir para futuras pesquisas envolvendo a poluição de ambientes com efluentes oleosos. Os dados coletados permitiram verificar a toxicidade e biodegradabilidade relativa dos óleos, de modo que os ensaios contendo biodiesel e óleo vegetal novo tiveram menor índice de biodegradação, quando comparado ao óleo automotivo usado.

Relações de gênero no cotidiano escolar: concepções, discursos e práticas

Gender‟s concept understands that differences and inequalities established between men and women are historically and culturally constructed. In this way, the meanings and representations of gender are constituted and reconstituted in the social realm through various institutions, practices and relationships presents in a social group. The school as an institution responsible for the formal education of children, youth and adults, produces and reproduce speeches that (re)constitute meanings, identities and representations of gender. Based on this assumption, this research aims at analyzing the routine practices of kindergarten and early elementary school years at a public school in the state of Sao Paulo about gender relations. Therefore, this study aims to broach how discourses and attitudes of teachers, students and other subjects produce and reproduce the representation and gender identities. Form this purpose, the study first presents a literature about the subject to later present the research results obtained through the questionnaire applied with teachers and the daily school practices‟ observe of the school

Antropologia da Civilização: um estudo da tradução para o inglês de termos simples, expressões fixas e semifixas recorrentes em duas obras de Darcy Ribeiro

The main purpose of this article is to investigate the most frequent simple terms as well as fixed and semi-fixed expressions in Social Anthropology of Civilization subarea in Portuguese and their corresponding terms in English, found in two works written by the anthropologist Darcy Ribeiro. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1995, 1996, 1997; CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004; KRIEGER &FINATTO, 2004). Results show that there are similarities and differences among the use of the terms in the main subcorpora composed of source and target texts and in the comparable corpora in Portuguese and in English. This data indicate that terms and expressions are not univocal in the anthropological language due to the differences in the conceptualization of the same referents by different specialists in the area.

A nova teoria da antropologia da civilização: tradução para a língua inglesa de neologismos terminológicos criados por Darcy Ribeiro nas obras o processo civilizatório e o povo brasileiro

This study analyzes the translation process into English of neologisms and expressions in the works written by the anthropologist Darcy Ribeiro and in their respective translations, made by Betty J. Meggers and Gregory Rabassa. Our research project draws on Corpus-Based Translation Studies (BAKER, 1995, 1996, 2000; CAMARGO, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and on some concepts of Terminology (ALVES, 1999; BARROS, 2004; BOULANGER, 1989; CABRÉ, 1993, 1999). Results show that terms do not present similarities within the language related to Brazilian Anthropology, being necessary for the author to look up alternative terminology and to create new concepts that can be used by other anthropologists. The translation of words and expressions developed by the author reflects lexical variation due to the options chosen by the respective translators for the target language. These tendencies may be found in Ribeiro’s translated texts, indicating the difficulty to conceptualize the anthropological Brazilian universe in English.

A tradução para o inglês de termos e expressões em Antropologia da Civilização: traços de explicitação em duas obras de Darcy Ribeiro

The main purpose of this article is to investigate the aspects of explicitation in English translation of terms and expressions in two of Darcy Ribeiro’s anthropological works. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1993, 1995, CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004). According to Baker (1996), explicitation is the tendency to explain, in the translated text, parts of the original text that had been left implicit. Results show that these tendencies may be found in Ribeiro’s translated texts, indicating the difficulty of conceptualizing the Brazilian universe in English.

O papel da tradução na construção da identidade da literatura afro-americana no Brasill

This paper discusses the role of translation in the construction of the identity of African-American literature in Brazil, by considering the relations between the Brazilian sociocultural context, infl uenced by biological and cultural miscegenation, and the particular way that the literary criticism represented by essays and translations of the Brazilian critic Sergio Milliet, published in between the 40’s and 60’s, approaches AfricanAmerican poetry, with special focus on Langston Hughes’ poems. In this paper, differences between Brazilian and American racial contexts are brought into light in regard to the discourses on miscegenation and race. It is discussed the extent to which Sergio Milliet developed a racialized identity for African-American poetry in his essays, which, however, was rebuilt through translation, in his anthology Obras Primas da Poesia Universal, with a less racialized perspective so that African-American aesthetics could sound less dissonant and regional and more inclined towards the principle of universality which characterizes the anthology composed of renowned foreign and Brazilian poets.

Coesão e coerência: discursos da linguística e da mídia

Esse trabalho analisa as refrações do discurso pedagógico que, em diálogo com outros discursos, como os da mídia e da linguística, reflete-os, além de ressignificá-los. Mais especificamente, trata-se da ressignificação que os discursos pedagógicos, postos em diálogo com os discursos da mídia, fazem de conceitos da lingüística; para essa análise tem-se como foco os conceitos de coesão e coerência, esses conceitos são critérios de avaliação dos textos. Quando retirados de suas enunciações e reutilizados nos dias de hoje, esses conceitos são ressignificados de forma a se adaptarem a novas enunciações. Como abordagem metodológica para a realização deste trabalho, tem-se uma análise qualitativa dialógica do livro de Thaís Nicoleti de Camargo, Redação linha a linha (2010) (corpus desse trabalho, que representa o discurso pedagógico). No diálogo proposto sobre os conceitos de coesão e coerência textuais pode-se perceber a ressignificação causada pela nova enunciação em que esses enunciados são reutilizados. Esse trabalho, por valer-se da análise do discurso bakhtiniana, estará sempre voltado ao conceito de diálogo, colocando os discursos em contato; partindo desse ponto, busca-se entender quais discursos dialogam com a produção do discurso pedagógico no livro analisado. Pode-se perceber, na análise dos conceitos de coesão e coerência textuais, que alguns discursos que dialogam com esses enunciados são os discursos de normatização e padronização. É possível dizer que a enunciação em que esses enunciados se produzem remete aos discursos do capitalismo, dos vestibulares, da atribuição de notas
