Aplicações de um potencial reativo no estudo da interação entre moléculas e superfícies bidimensionais

In materials science, the search for technological improvements have become one of the main subject of study of researchers. This is especially true in the case of materials with reduced sizes, in the nanometer scale. Important phenomena to be studied in these cases are the desorption and adsorption on two-dimensional materials, such as graphene. These phenomena are of great importance in the study of interactions between organic films, synthesis or catalysis of reactions on surfaces and even in the creation of nanoscale devices [1, 2, 3, 4]. Between the most important topics related to these phenomena are the storage of gases in low-dimensional systems and the study of nanostructured fuel cells or batteries. In this context we used two different parametrizations for the reactive force field ReaxFF to study the potential barriers and reaction barriers of our system. First we made a study about the Reaction Barriers and Energy Barriers for bonds between graphene and the following atoms: sulfur, fluorine, hydrogen, nitrogen and oxygen. It is important to have this information in order to make it possible to understand how these atoms react with the graphene sheet. Subsequently, we calculate reaction barriers for mixed structures where fluorine is a fixed element bonded to graphene and other element is simultaneously bonded to graphene. This other element (N, O, H or S) is varied in its possible relative positions (ortho, meta and para in relation to fluorine in either: the same side and in the opposite side of the graphene membrane)

Variáveis psicológicas no vôlei competitivo feminino: estudo da ansiedade e da vergonha

O contexto esportivo é repleto de muitas manifestações psicológicas. Para se ter sucesso é necessário que ocorra uma grande preparação destes atletas, que devem estar preparados fisicamente, tecnicamente e taticamente para responder às necessidades do esporte, buscando sempre a vitória e a melhor performance nas competições desportivas. A Psicologia do Esporte vem desenvolvendo programas de treinamento psicológico envolvendo técnicos, treinadores e atletas na busca de melhor desempenho nas competições. Hoje em dia o voleibol é um dos esportes mais praticados e assistidos no mundo inteiro, sendo no Brasil o segundo esporte mais praticado. O estado emocional se altera tanto em um período pré-competitivo, onde a incerteza de futuros acontecimentos provoca uma ansiedade, tensão e certo desconforto, quanto no momento da competição e também no período póscompetitivo. O sentimento de vergonha também é manifestado em muitas ocasiões. Várias são as definições encontradas para essa emoção: sentimento penoso de desonra; humilhação; rebaixamento; sentimento de insegurança provocado pelo medo do ridículo; embaraço; indignidade; timidez; acanhamento; sentimento de desconforto, entre outras. . A pesquisa buscou analisar teórica e praticamente as alterações emocionais de atletas em suas funções esportivas. Foi realizada com uma equipe de voleibol feminino, onde se aplicou um questionário fechado, a 21 atletas, com idades entre 13 e 16 anos. Verificou-se com que freqüência as manifestações dos sentimentos de vergonha e ansiedade ocorriam e possivelmente prejudicavam o desempenho das atletas. Após análise dos resultados pode-se concluir que as manifestações de ansiedade foram mais evidenciadas se comparadas as de vergonha. Notamos que, as preocupações quanto ao desempenho e aos erros que podem ser cometidos são muito evidenciados na equipe. A vergonha-meta... (Resumo completo, clicar acesso eletrônico abaixo)

Estudo de caso: aplicação do método DMAIC-White Belt- na redução de latas amassadas em uma produção de leite em pó

This work consists of the implementation of the steps Define, Measure , Analyze , Improve and Control ( DMAIC ) to develop a Six Sigma project in an industry the food industry. The objective was to demonstrate a potential for reducing the occurrence of crushed cans in potting milk powder industry in a White Belt project. The food industry accounts for about 9 % of Brazil's gross domestic product ( GDP ), generating thousands of jobs . Among the major sectors of the food industry is the manufacturing sector of milk , occupies approximately 10 % of the total turnover of the food industry . Brazil is considered today one of the eight largest producers of milk powder in the world. The milk powder is packed , mostly for aluminum cans that are lined internally with varnishes and other materials to protect the milk of metals from aluminum. When the cans are dented food protection is compromised and may lead ingestion causing dis-eases such as botulism. Aiming to solve the problem of dented cans methodology was used as a case study with a quantitative approach through the DMAIC method. Some quality tools used in each step of the project as brainstorming , cause and effect diagram , flowchart , ef-fort and impact matrix, 5W1H , among other Pareto diagram is presented . A survey about the disposal of cans in the company verifying a mean loss and, from this histor-ical , a goal loss was calculated was performed . With the target set we calculated the annual saving design . During application of DMAIC was found that the highest rate of loss occurred in transportation between the factory and the factory that fills cans milk . Several actions were taken to resolve problems that resulted in dented cans and the first two months of phase control it was found that the smaller losses calculated target resulting in a saving for the company. The short time of implementa-tion of the Improve phase did not allow a more detailed a ...

Estudo da influência da aplicação do fluido de corte no torneamento da liga de alumínio AA7075

One of the ways to minimize the effects of unproductive time caused by tool wear can be achieved by introducing an efficient system of lubrication and cooling in the process. However, in the last decade the research had the goal to restrict the maximum use of refrigerants and / or lubricants in metal-mechanical production. The important factors that justify this procedure include the operational costs of production, ecological issues, and the legal requirements of environmental conservation and preservation of human health. The purpose of the proposed work is the study of machining by turning with the focus on the influence caused by the application of cutting fluid in several ways of application (abundant and MQF) and also by comparing the results obtained by machining without the presence of fluid . For this purpose, the turning tests are conducted using an aluminum alloy (AA 7075). The response variables to be analyzed were obtained from the roughness (Ra and Ry), the stresses presented (VB) and their progression in relation to the cutting length achieved, the type of chip formed, in addition to changes in the degree of finish (roughness) presented by the turned parts. The results of this study should provide more detailed information about the actual influence of cutting fluids in turning this alloy, which are characterized by high rates of deformation when the formation of damaging your chip machining and also the quality of surface generated. Therefore, it is expected to provide subsidies to promote the optimization of machining this alloy making the most of the role of cutting fluid

Um estudo do significado da ética nos Parâmetros Curriculares Nacionais - Temas transversais e suas implicações no contexto da contemporaneidade

Este trabalho de pesquisa tem como objetivo identificar o significado da ética contida nos Parâmetros Curriculares Nacionais (PCN). Para tal meta, foi feita uma pesquisa bibliográfica de cunho epistemológico, que proporcionou o estudo dos significados da ética em uma perspectiva história – desde a Antiguidade, ao enfatizar os pensamentos de Aristóteles; na Modernidade com o filósofo Immanuel Kant para, posteriormente chegarmos à contemporaneidade e receber contudo, a contribuição de vários teóricos, dentre os quais destacamos: a visão construtivista de Yves de La Taille; e a ótica crítica de Pedro Goergen. Ao dar ênfase para a contemporaneidade, foi feita uma análise sobre a ética e a educação, contidas em seu contexto, em prol da realidade e da necessidade da ética, de acordo com diferentes percepções teóricas. Finalizamos esta pesquisa com a descrição do conteúdo da ética, presente nos Parâmetros Curriculares Nacionais (PCN) – Temas Transversais (TT) que, posteriormente analisou seu discurso baseado nos teóricos apresentados no transcorrer desta pesquisa. Neste momento, percebemos que a ética tem tido um papel histórico de propagação da moral existente na comunidade à qual se insere e esta, entretanto, sempre recebeu influências da classe pela qual é dominada. Na contemporaneidade, percebemos claramente esta realidade, sendo a ética hedonista moralmente propagada pelos meios de comunicação, pelos espaços públicos e privados, pela escola, etc. Com isso, ao pensar no campo educacional, os PCN, trazem a necessidade de uma educação moral na escola que inverta os valores morais existentes, para os valores referentes à justiça eqüitativa que está no discurso neoliberal atual. O qual visa solucionar os problemas advindos da modernidade desenfreada, porém sem modificar a lógica capitalista existente.

Estudo de termos simples, expressões fixas e semifixas encontrados em corpora paralelos e comparáveis da subárea de economia política

The main purpose of this investigation is to analyze the most frequent simple terms, fixed and semifixed expressions in the subarea of Social Political Economy in Portuguese and their corresponding terms in English, found in fifteen papers written by Bresser-Pereira and in his self-translated texts. The methodology used is the Corpus-Based Translation (Baker, 1992, 1993, 1995, 1996; Camargo, 2005, 2007), Corpus Linguistics (Berber Sardinha, 2004) and Terminology (Barros, 2004). Results show that terms and expressions used in the source texts have no univocity within the specialized language related to the Brazilian Social Sciences. The terms translated into English also reflect variation due to the options chosen by the selftranslator as he seeks to adapt the theoretical concepts to the possibilities of the Target Language.

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.

Intervenções com a atividade física em crianças e adolescentes com deficiência intelectual: uma meta-análise

Abstract Intellectual disability is development atypical conditions that involve issues on a number of factors, such as intellectual skills, adaptive behavior, interactions and social roles. Furthermore, they report higher rates of physical inactivity than the general population, as well as participating less and less of regular physical activity, as they grow and age. The participation of people with intellectual disabilities in physical activity programs promotes, benefits of prevention of diseases, particularly cardiovascular, improvement of intellectual and cognitive ability in addition, regular physical activity promotes reduction of body fat. Therefore the aim of this study was to identify through a systematic review, physical activity programs for adults with intellectual disabilities and their extension of the benefits, limitations and recommendations, moreover, the following objectives: to analyze the types of physical activity programs and determine which is the most suitable for adults with intellectual disabilities, and to determine the benefits that physical exercises programs entail for adults with intellectual disabilities. The initial electronic search resulted in 2808 manuscripts. The predetermined exclusion criteria were: review process of the studies involved reading titles, abstracts and full texts checking. After all these phases, eight manuscripts met the inclusion criteria of the review. Articles presented participants aged between 18 and 67 years with mild to moderate intellectual disability. The intervention period was from 2.5 months studies ranged up to 9 months and the weekly frequency was from one to three times a week. The intervention types differ between the articles analyzed, including leisure and recreation activities, combined exercises of strength and muscular endurance, aerobic activities of hiking, with races and exercise bikes, widespread activities and sports specialization, athletics and...
