O impacto das atividades antropogênicas sobre o meio ambiente é um tema de grande relevância atualmente, atraindo a atenção da comunidade científica em geral, visto que essas atividades têm causado alterações significativas na qualidade da água, do solo e do ar. Dentre a ampla gama de poluentes resultantes das atividades humanas, merece destaque a classe dos metais pesados, os quais possuem propriedades tóxicas e genotóxicas, constituindo fatores de risco para o desenvolvimento de desordens neurodegenerativas, artrite e câncer nas populações expostas a estes contaminantes, bem como alterações nos ecossistemas contaminados. Neste sentido, o presente trabalho teve por objetivo avaliar o potencial citotóxico, genotóxico e mutagênico do níquel como contaminante, utilizando Allium cepa (Liliaceae) como organismo-teste, a fim de detectar possíveis efeitos deletérios em seu material genético. Estas avaliações foram feitas por meio da exposição de sementes de A. cepa a três soluções, com diferentes concentrações de níquel. Os resultados obtidos no primeiro biensaio e na repetição estão apresentados na forma de artigo científico, a ser submetido para revista especializada. O estudo dos efeitos do níquel em A. cepa foram importantes, uma vez que os dados da avaliação dos danos induzidos neste organismo modelo podem ser utilizados para a comparação com modelos animais, sendo possível assim, a inferência dos perigos aos ecossistemas e à população que está exposta a esse contaminante

This paper was developed through literacy events (Barton, 2000) about English language, understood as a social practice of writing and reading. The subjects involved in this research were women, between forty and seventy years old, students of a Young and Adult Education Project (PEJA) that occurs at UNESP/Rio Claro, whose are looking forward to conclude basic school. We intended to see in their speeches reflections about the English language presence in our society and how they deal with this foreign language. Thus, we optimize this contact exposing those women to daily situations where English language was present. To foment dialog and ideas discussions, we brought to the classes common elements, materials such as street advertisements photos with words in English. We noticed that most students recognize the constant English presence and, even they never had formal English education, they were able to establish relations between the uses of English words in everyday Portuguese at most different spheres of life. And, at many times, foreign word comprehension is related to English words use instead of a native one leading to an English naturalization process in the Brazilians speeches world.

This study aimed to gather information about the social and linguistic reality of students 1. years of elementary school and community that came, in order to identify aspects of their lexical phonological levels, morphological and morphosyntactic and thus identify and describe the alternative variants of non-standard rule. The methodology chosen was that of variational sociolinguistics addressing quantitative and qualitative aspects in the treatment of the data collected through participant observation and audio recordings of speeches of the students. The results indicate that the level of phonological variants are the most frequent in the speech of students. Because the literacy phase, how the student speaks serves you a guide to the act of writing, so it is necessary to work with the students the difference between oral and written form and monitoring of these two modes according to the context of the discourse

Abstracts of scientific articles offer the first contact their readers have with the issues and results presented by the article, thus having a pivotal screening role. Due to their importance, they need to be well written, taking into account their genre-specific rules. Several studies have aimed at describing its particular textual structure, its rubric, though there is still much data to be amassed. The purpose of this work was to analyze a corpus of Chemistry abstracts, seeking the rhetoric categories that structure them in the sentence level and to describe its rubric. In order to do that, we have used lexical and grammatical evidence to categorise the rhetoric role each sentence has. We have found that the expected structure occurs, the main rhetoric focus being the presentation of results in the vast majority of cases. Furthermore, the occurrence of certain categories may depend on the size of the abstract, and certain rhetoric roles are embedded in others, especially the one describing method. The corpus has yet to be expanded to offer further results, two of them being to help non-native writers to better structure the textual level of their works and to build a software of automatic analysis of abstracts

The main objective of the presented study is the development of a predictive interval type-2 fuzzy inference system in order to estimate the mortality risk for a newborn, to be used as an auxiliary tool for decision making in medical centers where there is a lack of professionals for this purpose and, afterwards, to compare its performance to a type-1 fuzzy system. The input variables were chosen due to their acquisition ‘simplicity, not involving any invasive tests, such as blood tests or other specific tests. The variables are easily obtained in the first few minutes of life: birth weight, gestational age at delivery, 5-minute Apgar score and previous report of stillbirth. Databases from the DATASUS were used to validate the model. 1351 records from the city of São José dos Campos, a mid-sized city in the São Paulo state’s countryside, were considered in this study. Finally, an analysis using the ROC curve was performed to estimate the model’s accuracy

Este trabalho teve por objetivo analisar o estilo de João Ubaldo Ribeiro enquanto autotradutor e também compará-lo ao seu estilo enquanto autor, por meio de um corpus paralelo formado pelas obras Sargento Getúlio/Sergeant Getulio e Viva o povo brasileiro/An invincible memory. A fundamentação teórica apoia-se na abordagem interdisciplinar proposta por Camargo (2005, 2007) envolvendo os estudos de tradução baseados em corpus (Baker, 1996, 2000, 2004) e a linguística de corpus (Berber Sardinha, 2004). Para uma observação do seu perfil estilístico, procurei identificar usos linguísticos característicos e individuais, ou seja, traços de seu comportamento linguístico relacionados à variação vocabular. Quanto aos resultados, foi possível observar que, enquanto participante como autotradutor, Ubaldo Ribeiro revela um padrão estilístico distintivo e preferencial que apresenta menor variação lexical. Em contraste, na situação de participante como autor, Ubaldo Ribeiro mostra padrões estilísticos com maior variação. A diversidade de vocabulário já era esperada para o escritor João Ubaldo, uma vez que a crítica literária enfatiza a sua habilidade na exploração do verbo brasileiro. Ao considerar a forma padronizada como uma indicação do uso que o autotradutor faz da linguagem, pode-se destacar, apesar da influência de possíveis variáveis, que a diferença menor registrada para Sergeant Getulio (3,69) e acentuadamente mais baixa para An invincible memory (4,73) constituem marcas significativas da utilização dos padrões estilísticos próprios desse tradutor de si mesmo, revelando o impacto da extensão dessas diferenças em contraste com a escrita do autor, respectivamente em Sargento Getúlio e Viva o povo brasileiro.

In this article we address the search for equivalents in the elaboration of a model dictionary for sworn translators of terms used in bylaws, in the Portuguese-French translation direction. We present, specifically, some cases in which the morphological similarity between the two languages can lead to errors, for example false cognates.

The present paper aims at applying a model of bilingual onomasiological terminological dictionary, as proposed by Babini (2001b), for the development of an English-Portuguese and Portuguese-English electronic dictionary of the fundamental Artificial Neural Networks (ANN) terms. This subarea of Artificial Intelligence was chosen due to its use in several technological activities. The onomasiological dictionary is characterized by allowing searches of either lexical or terminological units from its semantic content. Our dictionary model allows two types of search: semasiological and onomasiological. The onomasiological search is made possible by a set of semes or semantic traits that make up the concept of each term in the dictionary.

The trade fair industry has great relevance in the national and international economic environment and it is constantly expanding. The general objective of this work is to analyze the main linguistic variants found in the trade fair terminological set. Our research is based on the theories of Cabré (1993, 1999), Barros (2004), Krieger & Finatto (2004), Alves (2007), Barbosa (2009), Dubuc (1985), Berber Sardinha (2004), Babini (2006) and Faulstich (1998, 2001). For this work we constitute two corpora of specialized texts, one for English language and another for Portuguese language. Successively we performed a collection of terms using software for corpora processing. These terms were organized into two notional systems, one in English and another in Portuguese. Then we analyzed the main types of variants found in our terminological set. Among them, those who had higher productivity are the lexical variants, followed by graphical, morphological and syntactic variants.
