Estudo do comportamento plástico, mecânico, microestrutural e térmico do concreto produzido com resíduo de porcelanato

Population growth experienced in major cities, allied to society s need of infra-structure, especially ones related to habitational demands, increases the consumption of construction materials. As a consequence, consumption of natural resources itself. Thus, due to this process, concrete is one of the most produced materials in civil construction. This is also due to the great diversity of its application, easiness in its execution and adequate mechanical performance, as well as low production costs. Following the same tendencies in construction development, the ceramic industry has intensified the production of porcelain ceramic tiles and floors. These are achieved by a fine finishing and receive polishing at the end of the fabrication process. This work researched the use of porcelain residues in polishing for the production of concrete. All of which; due to economical and environmental issues. This process aims to prove adequate destiny for this type of residue, due to environmental issues, incorporating it to the concrete itself; all of which provides economy in consumption of the materials that constitute concrete. Thus, the main characteristics of concrete were investigated through the inclusion of different concentration of the porcelain residue as additional trait element. The residue rates incorporated to the trait varied from 10% to 50% in relation to the cement mass, in the traits with plastic additives and without plastic additives. It is observed that the inclusion of porcelain residue produced a meaningful alteration in the consistency of fresh concrete. This residue has a fine granulometry and it considerably absorbed the water used in the concrete spreading, influencing the way this material is dealt with. Thus, the value of cement striking decreases with the increase of residues present in trait. The maximal incorporation of the residue was of 50%, massively, for the same factor water/initial cement. The use of residues in concrete results in an 40% increase in the compression resistance. It is also proportional to residue concentration of porcelain in the trait. The microstructure was also favored once porosity and concrete absorption decreases with the use of this residue. The parameters demonstrate the quality and durability of the concrete produced with this residue. The use of porcelain residue in concrete composition has not produced meaningful thermal behavior changes. Thermal conductivity, heat capacity and thermal diffusivity have been maintained basically constant

Estudo do perfil térmico de fornos do tipo "caipira" utilizados pelo setor de cerâmica vermelha em parelhas na região Seridó-RN

The present study aimed to characterize the thermal profile of wood fired oven used by the red ceramic industry in Parelhas, in the Seridó region/RN, aiming to propose structural interventions that can contribute to increasing productivity and product quality, optimize wood consumption and mitigate existing losses during the burning process. The study was conducted at Cerâmica Esperança in the city of Parelhas -RN, Brazil, during the period from August 2012 to September 2013. Four treatments were performed with three replicates, ie, with, a total of 12 experimental units (burnings). In the first stage 4 treatments were performed with three replicates, totaling 12 experimental units (firings). In the second stage 2 treatments were performed with three replications, totaling 6 experimental units (firings). The physical characteristics of the wood were analyzed using standard NBR 11941 and NBR 7190 for basic density and moisture, respectively. The clay was used as a reference parameter for distinguishing treatments. For both the analysis and characterization was carried out using techniques of fluorescence X (XRF) rays, X-ray diffraction (XRD) analysis, particle size analysis (FA). In the first and second stages were monitored: the time during the firing process, the amount of wood used at each firing, the number of parts enfornadas for subsequent determination of the percentages of losses, but also product quality. To characterize the thermal profile of the oven, we measured the temperature at 15 points scored in the surface charge put into the oven. Measurements were taken every 30 minutes from preheat until the end of burning, using a pyrometer laser sight sighting from preheating until the end of burning. In the second step 12 metal cylinders distributed on the oven walls, and the cylinder end walls 8 of the furnace 2 and rollers on each side walls are installed equidistant to 17 cm from the soil and the surface 30 of the wall are installed. The cylinders distributed on the front were placed 50 cm above the furnace, and the base of the oven 20 cm distant from the ground. 10 also thermocouples were installed, and five thermocouples distributed 1.77 cm above the combustion chambers, and one thermocouple on each side, and three thermocouples in front of the oven. We carried out the measurements of the temperatures every 1 hour during the burning two hours in cooling the cylinders with a pyrometer and thermocouples for dattaloger. These were fixed with depth of 30 cm from the wall. After statistical analysis it was found that: the thermal profile of the furnace surface and at different heights was heterogeneous; and the ranges of density and moisture content of wood are within recommended for use as an energy source standards. We conclude that even at low temperatures reached during firing there was a significant production of good quality products, this is due to high concentrations of iron oxide and potassium oxide found in clay, which lowers the melting point of the piece. The average burn time for each step varied 650-2100 minutes wood consumption was on average 20 m3, product quality was on average 16% of first quality, 70% second, third and 5% to 10% loss . The distance between the wire and the surface of the oven was a significant parameter for all treatments, but with different variations, meaning that the wire should not be so generic and unique form, used as a criterion for completion of the burn process. The central part of the furnace was the area that reached higher temperature, and in a unified manner, with the highest concentration of top quality products. The ideal temperature curve, which provided the highest quality of ceramic products was achieved in the central part of the furnace

Reestruturação produtiva na Petrobrás e ação sindical dos petroleiros do RN

Ce travail a l objectif d analyser la question de la restructuration productive dans la Petrobrás/ RN et les implications possibles sur l action syndicale du Sindipetro/RN pendant la période 1995 2003. La restructuration productive dans la Petrobrás/RN commence dans la décennie 1990 quand l entreprise, au niveau national, décide d adhérer au Programa Brasileiro de Qualidade e Produtividade PBQP lancé par le gouvernement Collor comme motivation et priorité pour que les entreprises s adaptent à l ouverture de l économie brésilienne au marché extérieur. De ce fait, la Petrobrás/RN afin de se maintenir dans le marché compétitif et mondialisé , adopte des techniques administratives basées sur la philosophie de la qualité totate, met au point des inovations technologiques et organisationnelles, tout en altérant sa base technique et adopte, encore, la tertiairisation de quelques activités visant à la reduction des coûts. De telles mesures ont atteint de façon remarquable l action du Sindipetro/RN qui commence alors à agir selon la logique de la politique néo-libérale du gouvernement de conduite anti-syndicale. Face à ces faits le syndicat a rédéfini ses actions dans le but de trouver des manières de poursuivre les luttes syndicales dans cette conjoncture de difficultés dans les relations de travail. Celui-ci s engage donc à entamer les négociations comme stratégie afin de préserver les privilèges de la catégorie et d éviter la perte des droits acquis

Reestruturação produtiva e terceirização : o caso dos trabalhadores das empresas contratadas pela Petrobrás no RN

This thesis is inserted on the discussion about the productive reframing and its reflexes concerning the world of work, in the current crisis stage in the capitalist way of production. This study deals with the impacts of outsourcing in relation to workers of companies subhired by Petrobras, in the State of Rio Grande do Norte, since decade of 1990. It is demonstrated that outsourcing in the oil sector, used mainly as a way to reduce costs of production, contributed to the raising of precarious conditions and relations of work. The transformation to the way of organization in the production, has intensified with the outsourcing, represented to the companies a bigger gain in productivity and a better control over the workers. These changings, that reconfigure the profile of the oil work force, allowed, among other things, reduction in numbers of the effective workers in the table of employees of Petrobras, the raising of relation concercing instable works, the raising in numbers of young workers, with a little or none qualification, reduction in the salary pattern of the professional class, illegal withholdment of labourite rights and the raising of risks to the health and security of the workers

Teorias implícitas dsos estudantes de Pedagogia sobre a docência nos anos iniciais do ensino fundamental

Esta tesis (desarrollada en la Base de Pesquisa, Formação e Profissionalização Docente da UFRN) concentra su ámbito de interés en el problema de la formación, de la profesionalización del pensamiento del profesor, buscando investigar las Teorías Implícitas de los estudiantes del Curso de Pedagogía sobre la docencia en los años iniciales de la Enseñanza Fundamental. La emergente necesidad de términos acceso a las Teorías Implícitas de estudiantes de Pedagogía (futuros profesores) sobre la docencia en los años iniciales de la Enseñanza Fundamental, a través de un instrumento de pesquisa que posibilite su aplicación en varios contextos formativos para contribuir con su proceso de profesionalización docente, constituye el problema analizado. La pesquisa tiene como objetivo elaborar un instrumento investigativo para estudiar las Teorías Implícitas de los profesores sobre la docencia en los años iniciales de la Enseñaza Fundamental. La complejidad del estudio nos ha llevado a integrar diferentes procedimientos metodológicos, según orientación del paradigma sociocultural, tales como: estudios exploratorios, a través de la revisión bibliográfica de la literatura especializada y técnica de trabajo creativo en grupo; técnicas normativas y psicométricas. A través de los estudios exploratorios identificamos y configuramos tres teorías profesionales de la docencia en los años iniciales de la Enseñanza Fundamental, las cuales presentan una importante relación con el Estado: la docencia como actividad laica, la docencia como actividad técnica y la docencia como actividad profesional. Para la configuración de la teorías, definimos siete subdominios estructurales de la docencia: función docente, concepción de aluno, contenidos de enseñanza, gestión de aula de clase, proceso formativo, condiciones de trabajo y naturaleza del grupo profesional. El cuestionario normativo ha sido el instrumento orientado para investigar las representaciones de los estudiantes a nivel de conocimientos establecidos y reglamentados por la cultura, como condición básica para investigar sus Teorías Implícitas sobre a docencia. El estudio ha constatado que los subdominios determinados para la comprensión del objeto de estudio están presentes, de manera reincidente, en la literatura especializada como los son representativos en las identificaciones de los estudiantes investigados. Hemos concluido que las teorías configuradas para caracterizar la profesión docente en los años iniciales de la Enseñanza Fundamental hacen parte de la estructura de conocimientos de los estudiantes sobre la docencia, aunque los enunciados de las teorías, como actividad laica y como actividad técnica, no presente índice de tipicidad y de polaridad muy significativo cuanto aquellos relativos a la teoría de la docencia como actividad profesional. Las Teorías Implícitas de los estudiantes enseñan que ellos comparten elementos o rasgos de todas las teorías de la docencia, aunque se revelen más predispuestos a la docencia como actividad profesional. El estudio orienta la aplicación del cuestionario reglamentado a un grupo de profesores actuantes en el nivel de enseñanza en cuestión, para que averigüemos si los enunciados que hacen parte de la estructura de conocimientos de los profesores son los mismos que componen la estructura de conocimiento de los estudiantes, de modo a fortalecer la validación de nuestro instrumento de pesquisa

Valorização do servidor no Programa Nacional de Humanização: estudo em um hospital universitário

It is at the work environment where value of the health professional is realized, according to the National Humanization Policy (PNH) from a Pediatric Hospital connected to an institution of higher education. Among the guiding principles of PNH it is highlighted the commitment to the democratization of labor relations and enhancement of health professionals, stimulating the continuing education process. For this research, a qualitative approach was chosen, using a semistructured interview as a tool to collect data. In a perspective of identifying the appreciation and humanization into interpersonal relations between workers, information from the theory of communicative action of Habermas was analyzed, considering cultural values goes beyond the practice in action, where the prospects of moral arguments in the universal truisms of life pervade original cultural moral, cognitive and expressive, imbued on ethics. This reasearch had the collaboration 29 employees with a regular contract labor to a teaching hospital in Natal, Brazil. The data was obtained through interviews which all participants signed a consent term. After data analysis the results shows the existance of a satisfaction of all workers on performing duties. The workers perceive its role valorization through kudos received as a consequence of a work done, others believe that it occurs when the institution or the group itself is concerned to enhance the work. Thus, in general, they feel valued. Regarding the interpersonal relationship, the most highlighted point was the fact that in the employees versus general directors item, respondents indicated the existence of a distance between these two categories, which can affect a participatory management. Therefore, the results of this study showed the necessity to develop actions that provide a healthy work environment. The joint guidelines of the PNH and the Employee Health Care Policy, represent some directions with some similarities in their purpose to the theory of communicative action, where there is a mutual respect, tolerance and coexistence of differences, considering the constructive conflict among health workers within the perspective of communication and interaction among individuals

Terapia comunitária integrativa: construção de um espaço de escuta para os trabalhadores na atenção básica da saúde

This research, which appears in the form of a dissertation, entitled: Integrative Therapy Community: construction of a listening space to health care workers in primary care, addresses the Integrative Community Therapy (ICT) as a tool to create meeting spaces between health professionals where they can be receptive among one another. With the completion of this study aimed to analyze the ICT as a therapeutic approach and space of listening and speaking for health professionals cited here in order to identify their anxieties, doubts, worries and uncertainties arising from the context of labor relations and the impact of therapeutic experiences under the view of the participants. It was developed as an action-science research, involving several steps. The field of research was the ICT meetings of workers from the units under the Family Health Strategy of Northern Health Districts I and II of the city of Natal, using a qualitative approach. The interpretation of data collected was based on content analysis proposed by Bardin. Finally, this study showed the ICT as a space for dialogue and sharing, with repercussions on labor relations and expansions beyond the ICT meetings, reaching out to family and social relationships, contributing to creating bonds and solidarity networks. Under the view of the participants it was recognized as an experience that optimized the socialization, promoting the alleviation of suffering and increasing the well-being. Based on the study findings, it is inferred that ICT can be considered a viable tool for the receptiveness and humanized care of health care workers.

Sistema Híbrido de Inferência Baseado em Análise de Componentes Principais e Redes Neurais Artificiais Aplicado a Plantas de Processamento de Gás Natural

Nowadays, where the market competition requires products with better quality and a constant search for cost savings and a better use of raw materials, the research for more efficient control strategies becomes vital. In Natural Gas Processin Units (NGPUs), as in the most chemical processes, the quality control is accomplished through their products composition. However, the chemical composition analysis has a long measurement time, even when performed by instruments such as gas chromatographs. This fact hinders the development of control strategies to provide a better process yield. The natural gas processing is one of the most important activities in the petroleum industry. The main economic product of a NGPU is the liquefied petroleum gas (LPG). The LPG is ideally composed by propane and butane, however, in practice, its composition has some contaminants, such as ethane and pentane. In this work is proposed an inferential system using neural networks to estimate the ethane and pentane mole fractions in LPG and the propane mole fraction in residual gas. The goal is to provide the values of these estimated variables in every minute using a single multilayer neural network, making it possibly to apply inferential control techniques in order to monitor the LPG quality and to reduce the propane loss in the process. To develop this work a NGPU was simulated in HYSYS R software, composed by two distillation collumns: deethanizer and debutanizer. The inference is performed through the process variables of the PID controllers present in the instrumentation of these columns. To reduce the complexity of the inferential neural network is used the statistical technique of principal component analysis to decrease the number of network inputs, thus forming a hybrid inferential system. It is also proposed in this work a simple strategy to correct the inferential system in real-time, based on measurements of the chromatographs which may exist in process under study

Efeito da adição de colesterol e ecdisona na produção in vitro do baculovírus spodoptera frugiperda MNPV

Among the pests that attack corn crop in Brazil, there is Spodoptera frugiperda (JE Smith, 1797) (Lepidoptera: Noctuidae), known as fall armyworm, which is the major corn pest. Due to genetic instability during serial passage of baculoviruses in insect cell culture, the viral bioinseticides in vitro production development is the greatest challenge for mass production of this bioproduct. Successive passages of virus using extracellular viruses (BVs), necessary during viral bioinseticides production scaling up, leads to the appearance of aberrant forms of virus, a process so called as "passage effect ". The main consequence of passage effect is the production of occlusion bodies (OB) decrease, preventing its production using in vitro process. In this study, it was carried out a serial passage of baculovirus Spodoptera frugiperda multiple nucleopolyhedrovirus, isolate 18, using Sf21 cells. A decrease in the production of occlusion bodies from 170 to 92 in the third to fourth passage was observed. A factorial experimental design (22) was employed to verify the influence of two input variables, concentration of the hormone 20 - hydroxyecdysone (CH) and cholesterol (CC) on the values of response variables (volumetric and the specific OB production) of the process, seeking to define the optimum operating ranges trying to reverse or minimize the passage effect. The result indicated a negative influence of the cholesterol addition and positive effect in the hormone supplementation which the optimum range found for the concentrations studied were 8 to 10μg/mL and 5 to 6.5 mg / mL, for cholesterol and hormone concentrations respectively. New experiments were performed with addition of hormone and cholesterol in order to check the influence of these additives on the OB production independently. While the best result obtained from the factorial experiment was 9.4 x 107 OB/mL and 128.4 specific OB/cell, with the addition of only 6μg/mL 20-hydroxyecdysone these concentrations increased to 1.9 x 108 OB/mL and 182.9 OB/cell for volumetric and specific OB production, respectively. This result confirms that the addition of the hormone 20-hydroxyecdysone enhances the SfMNPV in vitro production process performance using Sf21 cells

A perspectiva do lazer entre lideranças sindicais das áreas metropolitanas de São Paulo e de Lisboa

We intended, in this study, to understand the sense of the leisure, due to the new work relationships in times of globalization, for syndical leaders that act in entities of metropolitan areas of São Paulo (Brazil) and Lisbon (Portugal). The methodology used was Phenomenology, Situated Phenomenon. Based on the data originated in the interviews, we established the following thematic categories: A) The request for the reduction of the work day, B) Actions related to the use of the leisure, C) Leisure as recovery for the work. We consider that in the globalization times, after diverse conquests of the workers, unhappily, we have attended in the last few decades, increasing precariousness of rights of the workers in the two searched countries, generating unreliability of the worker ahead of the experience of its work and of its leisure in independent way, it exempts, creative, significant and humanized.

Contato corporal entre adolescentes através da dança de salão na escola

The objective of this study was to identify the reaction and perception of adolescents in relation to body contact as well as emotional expressions through ballroom dancing. Forty-two adolescents from a public elementary school in the state of São Paulo participated in the study. Data gathering was conducted in groups by filming the ballroom dance class and applying a questionnaire about the experience. The dance experience was observed to provide greater body proximity and demonstration of affection, since part of the participants reported well-being, while others reported being embarrassed by dancing with a partner from the opposite sex. It was concluded that more dance activities related to biopsychosocial development need to be offered at school since ballroom dancing can help in interaction promoting body contact and thus facilitate in the process of interpersonal relations between adolescents.

Caminhos e descaminhos da adesão ao tratamento anti-hipertensivo :um estudo com usuários do Pacha (Programa de Assistência e Cuidado da Hipertensão Arterial) do Hospital Universitário Onofre Lopes

The high blood pressure is a multifactorial chronic disease which possesses emotional and social features in the illness appearance and evolution and in the adherence to the treatment which involves a decision-making through patient so that he or she process the necessary changes on harmful living habits. Adhesion, traditionally, it is referred to the patient to answer to the doctor orientations or of other health professional, about the appearance to the appointment with a doctor, about the use of medicine or lifestyle changes and maintaining this adhesion is the main problem to be overcame. It is expected the adhesion will ever be a continual, stable and satisfactory action, disregarding the complexity of subjectivity processes which permeate the sicken. This research aimed to investigate the difficulties which the person with high blood pressure has to adhere to the treatment, from the signification processes which give sense to the actions dealing with the adhesion. The study was carried out with 48 users of assistance program to the high blood pressure patient from Hospital Universitário from Natal RN, between 40-65 age. The answers were submitted to a double analysis process: 1) answer systematization in categories and codes and admission in statistical program SPSS (Statistical Package of Social Science), for generation of descriptive statistics; 2) Sense and signification analysis which permeated the deepener statement and interpretatively. The greater difficulties found are present on low-salt and law-calorie diets, in the dealing with everyday feeling and stress, being these factors cited as direct motive to the high blood pressure, regardless of interviewee s sex. It is observed there is not adhesion, but adhering, as an experienced everyday process. This work contributes with its results, assessing the used strategies by program with the aim of increasing the adhesion rates

Utilizando Pesos estáticos e dinâmicos em sistemas multi-classificadores com diferentes níveis de diversidade

Although some individual techniques of supervised Machine Learning (ML), also known as classifiers, or algorithms of classification, to supply solutions that, most of the time, are considered efficient, have experimental results gotten with the use of large sets of pattern and/or that they have a expressive amount of irrelevant data or incomplete characteristic, that show a decrease in the efficiency of the precision of these techniques. In other words, such techniques can t do an recognition of patterns of an efficient form in complex problems. With the intention to get better performance and efficiency of these ML techniques, were thought about the idea to using some types of LM algorithms work jointly, thus origin to the term Multi-Classifier System (MCS). The MCS s presents, as component, different of LM algorithms, called of base classifiers, and realized a combination of results gotten for these algorithms to reach the final result. So that the MCS has a better performance that the base classifiers, the results gotten for each base classifier must present an certain diversity, in other words, a difference between the results gotten for each classifier that compose the system. It can be said that it does not make signification to have MCS s whose base classifiers have identical answers to the sames patterns. Although the MCS s present better results that the individually systems, has always the search to improve the results gotten for this type of system. Aim at this improvement and a better consistency in the results, as well as a larger diversity of the classifiers of a MCS, comes being recently searched methodologies that present as characteristic the use of weights, or confidence values. These weights can describe the importance that certain classifier supplied when associating with each pattern to a determined class. These weights still are used, in associate with the exits of the classifiers, during the process of recognition (use) of the MCS s. Exist different ways of calculating these weights and can be divided in two categories: the static weights and the dynamic weights. The first category of weights is characterizes for not having the modification of its values during the classification process, different it occurs with the second category, where the values suffers modifications during the classification process. In this work an analysis will be made to verify if the use of the weights, statics as much as dynamics, they can increase the perfomance of the MCS s in comparison with the individually systems. Moreover, will be made an analysis in the diversity gotten for the MCS s, for this mode verify if it has some relation between the use of the weights in the MCS s with different levels of diversity
