Importância da avaliação do ciclo de vida na análise de produtos: possíveis aplicações na construção civil

Much has been discussed lately about reusing waste in new construction materials and countless studies have been carried out based on this objective. However, before these products can be called “sustainable” and a recycling system can be effectively implemented, it is fundamental for all the aspects involved in this action to be understood, and more important, what are the true gains for the productive sector and what are the benefits for the environment if this was to occur. In order to obtain a general framework for all environmental aspects and potential impacts associated with these products, over their entire life cycle, the most appropriate methodology is the Life Cycle Assessment (LCA). In view of the above, the objective of this work is to provide an overview of current studies of LCA, its history, its importance, its standards and the methodology employed and its applications related to civil construction. It is expected, to obtain a more complete scenario of the influences from a study of LCA, as well as establishing a contribution for the assessment of specific products and processes for civil construction, disseminating the importance of the use of this tool within the sector.

Construção e validação de um questionário para análise de concepções bioéticas

In this paper we describe the stages of a quantitative questionnaire development that allows the investigation of conceptions about bioethical values inherent to the scientific activity. This questionnaire was statistically and semantically validated and developed according to the Likert scale. The relevance of this instrument is given by the fact that, unlike what happens in European countries, quantitative research in Brazil has little educational traditions. Therefore, this work is intended to subsidize the use of quantitative methods in Education research that lack such tools.

Formação de professores: o campo dos afetos e a construção da identidade

In my participation at the project of extension Possibilities and events from childhood experiences and pictures cut out for a job with teachers , accomplished with teachers and coordinators of nursery school, which aims to discuss the training of teachers through the field of affections, I developed a reflection on traditional teacher training methods which tend to assign an identity to the professor. From this reflection it is necessary a theoretical deepening about the constant attempt to assign a specific and absolute identity to the professor, the need in the human being to produce sense and, bypassing the concept of intimacy, as these things are intertwined. In this work, with the bibliographical research methodology, present as objective: to present the possible definitions and explanations of the concepts ' production of meaning ', ' identity ' and ' intimacy '; relate these concepts and analyze the possible to train teachers according to a model, saying that this would be the ideal identity of professor

A construção dos processos de sistematização em processos aritméticos da EJA: um estudo

A proposta deste estudo teve início a partir das dificuldades apresentadas na formalização e sistematização dos cálculos matemáticos, por um grupo de alunas da Educação de Jovens e Adultos, em uma Escola Municipal de Rio Claro- SP. A pesquisa, que ora proponho, visa entender a importância das experiências e vivencias trazidas por pessoas com baixa ou nenhuma escolaridade, para entendermos o porquê de fazerem cálculos mentais matemáticos com alguma facilidade e encontrarem grandes dificuldades na sistematização/ formalização desses cálculos e como os jogos lúdicos matemáticos podem ser considerados fundamentais nesse processo de formalização das contas. Essa dificuldade, muitas vezes, repercute em entraves na escolarização regular dessas pessoas. Para pensar nessa problemática inicialmente elegemos como referenciais e materiais teóricos autores como Danyluk, Freire, Fonseca, Vigotsky, entre outros; são estudiosos que vêm contribuindo para a compreensão dos referidos processos e da linguagem matemática. No que concerne às experiências, buscaremos aportes em Larrosa. Em continuidade, será organizado um estudo baseado em registros, documentos e relatos de um acompanhamento da estagiária de aulas de matemática em uma sala de EJA, do Programa Institucional de Iniciação a Docência- PIBID que vem acontecendo na cidade de Rio Claro- SP, desde o ano de 2010. Os procedimentos de análise nortear-se-ão, além dos autores citados acima, pela análise do material gerado por meio dos registros, obtidos em sala de aula, pautando-nos pelas categorias de codificação (BOGDAN & BIKLEN). Entendemos que levantar elementos e analisar essas dificuldades podem contribuir para a compreensão do processo de construção da cultura e linguagem matemática, por essas pessoas, podendo assim contribuir para um novo olhar sobre a educação matemática nesse segmento da educação

Metodologia de determinação de funções de pertinência de controla-dores fuzzy para a avaliação energética de empresas de avicultura de postura

The objective of this work is to determine the membership functions for the construction of a fuzzy controller to evaluate the energy situation of the company with respect to load and power factors. The energy assessment of a company is performed by technicians and experts based on the indices of load and power factors, and analysis of the machines used in production processes. This assessment is conducted periodically to detect whether the procedures performed by employees in relation to how of use electricity energy are correct. With a fuzzy controller, this performed can be done by machines. The construction of a fuzzy controller is initially characterized by the definition of input and output variables, and their associated membership functions. We also need to define a method of inference and a processor output. Finally, you need the help of technicians and experts to build a rule base, consisting of answers that provide these professionals in function of characteristics of the input variables. The controller proposed in this paper has as input variables load and power factors, and output the company situation. Their membership functions representing fuzzy sets called by linguistic qualities, as “VERY BAD” and “GOOD”. With the method of inference Mandani and the processor to exit from the Center of Area chosen, the structure of a fuzzy controller is established, simply by the choice by technicians and experts of the field energy to determine a set of rules appropriate for the chosen company. Thus, the interpretation of load and power factors by software comes to meeting the need of creating a single index that indicates an overall basis (rational and efficient) as the energy is being used.

Estudo para determinação de uma metodologia para o ensaio de arrancamento que avalia aderência aço/concreto

This work talks about the importance of the steel adhesion to concrete, reinforced concrete structures, their testing and forms of measurement used and how the results are used in the structural design, which uses as a reference the NBR 6118 and NBR 7480. It also deals with the importance of a reliable assessment, discussing failures that the test used, NBR 7477, features in specific circumstances, as discussed under the EC-094. It also presents an initial proposal for simplified pullout test, which aims to analyze the grip on steel bars with diameter less than 10 mm, which results when used standardized testing by ABNT NBT 7477, has shown excessive variability, the main criticism of the trial today used without distinction to be established thick or thin bars. The proposal also presented methodology is in the consolidation phase, given the time and the volume of necessary tests. For this reason it is not possible to make a comparison between the values obtained and the results of the test used on the basis of the standard in force, this can only be done once the front with a continuation of this work
