Ser professor de português: o que dizem os discursos reguladores, os alunos e os professores no contexto da formação inicial (UMINHO/Portugal e UFRN/Brasil)

The constitution of being a teacher of Portuguese occurs in a dynamic process involving various factors, such as the requirements of regulatory documents, the context of teacher formation, and the configuration of current society, per se. This study is aimed at reflecting on the initial formation of teachers of Portuguese and on official documents that face this formation, raising the following questions: (1) what does it mean to be a Portuguese teacher? (2) what is the vision of the subjects (teachers and students) involved with the formation of teaching the Portuguese Language? (3) how do these individuals deal with official documents? and (4) how do these subjects discourses relate? To understand the context of the formative processes and the knowledge inherent in them, first we take the studies of Garcia (1999) and Tardif (2002) as a theoretical framework, and to understand and interpret the utterances of the interviewees, we were grounded in the writing of Bakhtin (2003), for whom the object of the Humanities, the sciences of man, is the text, since man is, by nature, an expressive being. We situate this study in the framework of qualitative research. It is a multiple case study that focuses on two contexts: formation of teachers of Portuguese at the University of Minho, Portugal, and the Federal University of Rio Grande do Norte, Brazil. The data that make up the research corpus come from documents elaborated by the Ministries of Education of Portugal and Brazil and were adopted by the two teacher formation institutions cited, from individual interviews involving eight trainer teachers (four from each university), and from two group-interviews (one in each institution), done with students in training. Our analysis is divided into three stages: first, document analysis; second, analysis of the discourse of the teachers in both contexts studied; and, third, analysis of the speech of the students in training. It is noteworthy that our purpose in this research was not to come out with a definition like being a teacher of Portuguese is X, but we are interested, above all, in discussing the issues surrounding initial formation, seeking different points of view, and hearing voices coming from different social positions for better understanding our object of study. Our analysis reveals that the initial formation of teachers of Portuguese, both in Portugal and Brazil, occurs in a complex way, under the influence of various factors, including: (a) difficulties in having the individuals involved adapt to the demands of regulatory agencies; (b) students and teachers adequacy to the organizational model of the post-secondary institution; (c) teachers difficulties to deal with the learning problems of students who have limited schooling basis and come from distinct socioeconomic realities; (d) a search for the establishment of methodologies for teaching and learning the Portuguese Language more adequate to reality; and (e) a search for a definition of professional knowledge needed for the teaching practice

Uso de resíduo e de minerais de pegmatito da região do seridó RN e de argilas portuguesas em formulações de grês porcelanato

In the State Rio Grande do Norte, Brazil, the most significant deposits of minerals in the production of granite and pegmatite are Seridó region. Municipalities of Parelhas and Equador are the main responsible for the production of feldspar, quartz, kaolin and granite. The ceramic industries are always in search of competitiveness by investing in new products or improving existing techniques. The stoneware is a type of pottery that stands in the market because it presents technical and aesthetic characteristics superior to other existing products. Characteristics of the raw materials initially obtained with chemical analysis and mineralogical analysis are crucial in getting a product that satisfies the conditions in a manufacturing process and is, in principle, directly related to the firing cycle. This research aimed at developing new formulations for the mass production of ceramic stoneware. The raw materials initially characterized were feldspar, quartz, kaolin and granite. As part of the research was developed at the University of Aveiro, in Portugal, we used two clays used in the production of Portuguese ceramics. The raw material Brazilian and Portuguese and the final product, both in Portugal and Brazil, were analyzed for X-ray fluorescence, X-ray diffraction, granulometric analysis, dilatometric analysis, thermal analysis and analysis of scanning electron microscopy (MEV). The specimens prepared at the University of Aveiro (DECV) were sintered at 10000C and 12000C and the specimens prepared in UFRN were sintered at 10000C, 10500C, 11000C, 11500C, 12000C, 12500C and 13000C, but the best results and demonstrating the presence of the mineral mullite were at temperatures of 12000C, 12500C and 13000C. The results showed that the granite waste used may be considered raw material of excellent quality for use in the ceramic industry and coating floors and more accurately by the industry of stoneware. Physical and mechanical tests conducted on samples of the formulations F01 and F02 developed in UFRN showed a water absorption and mechanical strength suitable for the stoneware

Arquitetura, cidade e território no Brasil colonial: a contribuição dos carmelitas calçados da Bahia e Pernambuco (1580-1800)

This study investigates the religious group named 'shoe wearing carmelites' (or Calced Carmelites) from Brazil´s Order of Carmo, from 1580 until 1800, in the Capitaincy of Bahia de Todos os Santos (Recôncavo, city of Salvador and Sergipe) and in the Capitaincy of Pernambuco (Alagoas, Pernambuco and Itamaracá). The study does not include the religious group known as the 'Reformed' Carmelites from Goiana, Recife and Paraíba convents. The Order of Carmo is a religious order from the Roman Catholic Church, founded in the 12th century. By the 16th century they were split into 'Calced' and 'Discalced'. In 1580 the Calced ones came from Portugal to Brazil, built convents in urban areas and were able to acquire slaves, farms and other assets. As any other religious order, the Carmelites had their modus operandi. This work emphasizes the way they operated or acted in the city, either individually or in association with other Carmelite religious foundations elsewhere (networking). Their action affected, although indirectly, the building of some specific aspects of the architecture, the city and the territory in colonial Brazil. The main objective of this study is to demonstrate the impact of the Calced Carmelites from Bahia and Pernambuco upon the territory of colonial Brazil, which is analyzed according to three scales: 1) the region or interurban; 2) the city or intraurban; 3) the building or the architecture. The research employs the comparative method of analysis, especially for the architectural scale. The work demonstrates that although not acting as architects or urbanists, the Carmelites contributed to the formation of the colonial territory of Brazil, behaving as a well-articulated and hierarchized religious network, from an economic and social perspective. Moreover, they influenced the emergence and growth of several colonial urban nuclei, from Bahia to Pernambuco, mainly in the surroundings of their religious buildings. Finally, it is very clear this religious order’s contribution to colonial architecture, as it can be seen by the architectural characteristics of the convents and churches which have been analyzed, many of which still stand in a good state of conservation nowadays.

Estudo e desenvolvimento de um capacitor eletrolítico de nióbio

It seeks to find an alternative to the current tantalum electrolytic capacitors in the market due to its high cost. Niobium is a potential substitute, since both belong to the same group of the periodic table and because of this have many similar physical and chemical properties. Niobium has several technologically important applications, and Brazil has the largest reserves, around 96%. There are including niobium in reserves of tantalite and columbite in Rio Grande do Norte. These electrolytic capacitors have high capacitance specifies, ie they can store high energy in small volumes compared to other types of capacitors. This is the main attraction of this type of capacitor because is growing demand in the production of capacitors with capacitance specifies increasingly high, this because of the miniaturization of various devices such as GPS devices, televisions, computers, phones and many others. The production route of the capacitor was made by powder metallurgy. The initial niobium powder supplied by EEL-USP was first characterized by XRD, SEM, XRF and laser particle size, to then be sieved into three particle size, 200, 400 e 635mesh. The powders were then compacted and sintered at 1350, 1450 and 1550°C using two sintering time 30 and 60min. Sintering is one of the most important parts of the process as it affects properties as porosity and surface cleaning of the samples, which greatly affected the quality of the capacitor. The sintered samples then underwent a process of anodic oxidation, which created a thin film of niobium pentóxido over the whole porous surface of the sample, this film is the dielectric capacitor. The oxidation process variables influence the performance of the film and therefore the capacitor. The samples were characterized by electrical measurements of capacitance, loss factor, ESR, relative density, porosity and surface area. After the characterizations was made an annealing in air ate 260ºC for 60min. After this treatment were made again the electrical measurements. The particle size of powders and sintering affected the porosity and in turn the specific area of the samples. The larger de area of the capacitor, greater is the capacitance. The powder showed the highest capacitance was with the smallest particle size. Higher temperatures and times of sintering caused samples with smaller surface area, but on the other hand the cleaning surface impurities was higher for this cases. So a balance must be made between the gain that is achieved with the cleaning of impurities and the loss with the decreased in specific area. The best results were obtained for the temperature of 1450ºC/60min. The influence of annealing on the loss factor and ESR did not follow a well-defined pattern, because their values increased in some cases and decreased in others. The most interesting results due to heat treatment were with respect to capacitance, which showed an increase for all samples after treatment

"Antes que eu esqueça : trajetórias, laços e memórias produzidas por sujeitos da terceira idade na interação em territórios de sociabilidades

Currently the number of elderly in the world and Brazil is growing increasingly. However, old age is still presented as a complex issue that needs more depth. It is extremely important that society should create a discourse committed to reviewing negative stereotypes of old age as well as studies that allow the construction of new looks inclusive , as well as the creation of public policies that favor the elderly category, such as the National Policy and Elderly Statute established recently. The aim of this study is to analyze the spaces of sociability for the elderly Mossley and understand how the collective experiences in these environments influence the quality of life and influence in their depictions of the elderly subjects. To collect data observations were made, semi-structured interviews and wheels conversations with men and women aged 65 to 80 years old, retired, mostly widows, neighborhood residents Abolition in Mossley, participants (CCI) Coexistence Center Seniors Jose Sarney and (CRAS) Reference Center and Welfare. Thus, the spaces facing the elderly are presented as a good alternative for the rehabilitation, the fun and preserve their memories, while the agents posing as productive, active, and transformers of their reality

Narrativas do Brasil nas memórias de Pedro Nava

This thesis is a translation of work of the Brazilian doctor, Pedro da Silva Nava (1903-1984), in particular, his memoirs and chronicles, articulated with the writings of medicine history, aiming to defend that the autobiographical narratives are sources of research capable of promoting discussions on the expansion of the present at the confluence of complex and unequal society in constant changing process as the Brazilian. The theoretical and methodological support circulates around studies, proposals and thesis by Boaventura Santos about empowering past, destabilizing subjectivity, sociology of absences, cosmopolitan reason and translation work. The empirical support drawn from the literature produced by Nava were analyzed with reference this reasoning and studies that have facilitated the flow of translation among others, the studies of Antonio Candido, Arrigucci Jr., Boris Cyrulnik, Beatriz Sarlo, Ecléa Bosi, Ítalo Calvino, José Willington Germano, José Maria Cançado, Lev Vygotsky, Marilena Chauí, Paul Ricöeur and Walter Benjamim, without neglecting what we consider indispensable to scientific research, the production of relevant knowledge and prudent, in view of a decent life. The initial inflections reflect the subject of the Memoirs and its education/training, to then place the Memoir subject in the literary context, scientific, historical and Brazilian poetic (1972-2010), bringing great interpreters and discussing the rationale used by the Narrator that we defend stand closer to the cosmopolitan, showing the formation of narratives whose presence insert itself beforehand to modernist verve, linked to the discursive array against the literature as domination space, disseminated in Brazil in the early twentieth century. So, it articulate with those in which the concerns adjust the construction of the social formation of Brazil as a national heritage through literary narrative that focuses on a historical principle that becomes the past empowering, allowing his rereading, whose converge to memory, the lifestyles, the plurality of language and Brazilian culture, formed by several people, converging into a design not of culture but multiculturalism in Brazil. The memory issue was addressed in the space-time of experiences of being that narrates, shaped by a destabilizing subjectivity that sought to order the testimony of a time, a history and society, retelling them by creative imagination, almost fictional, to make circulate his knowledge about Brazil attached to his medical knowledge, as well as other subjects in his living group and other groups with whom they maintained contact. Thus, he portrayed both tangible and intangible cultural assets of the country as a form of preservation, giving them meanings and sense. It approaches, therefore, from the perspective of sociology of absences, the expansion of the present and by the logic inherent in his narratives of self and Brazil

A concretização do princípio da igualdade em matéria tributária por meio de sentenças aditivas

This work aims to study the additive decisions, a type of juridical interpretation developed in foreign legal systems and which are known in Italy as adittive sentences. Thefore, this dissertation is based on theorical studies developed around the subject in Italy and Brazil. Considering the fact that the fundamental rights face a problem of implementation, being decreased its normative force when there are legislative partial omissions lacking constitutional justification creating privileges to certain individuals or social/economical groups over others, the method of additive interpretation according to the Constitution can be used in order to realize the principle of equality. In tax matters the subject is even more relevant in the way that it represents an important role in the economy. Partial legislative omissions can generate inequalities, favoring certain taxpayers in relation to others in similar legal situation. In these cases the privilege may have a negative impact on economic order restricting values related to the basis of market competition. On those occasions, Brazilian Judges and Courts must exercise their constitutional jurisdiction in order to expand the effects of the legislative omissions, based on the principle of equality by extending the standard to equal tax situations in order to maintain neutrality in taxation

Biomassa e desenvolvimento sustentável e sócio regional no Brasil: uma análise à luz da Constituição Federal de 1988

It is verified worldwide an increasing concern with the protection of natural resources in the planet, a fact that became relevant in Brazil since the promulgation of the Constitution of 1988, based on the viewpoint of sustainable development, which seeks to promote economic activities in the country according to the need for conservation and preservation of natural resources for the use of present and future generations. In addition, we seek to reduce the differences that occur in our society by determining as a fundamental objective to be persecuted by the Federative Republic of Brazil the reduction of social and regional inequalities. A value that should also be observed in the context of economic activities developed here, since it is a general principle of financial and economic order of the country. Therefore, considering the exhaustion of world s reserves of fossil fuels, as well as the impacts on the environment, especially for the large emission of greenhouse effect gases, the debate about the need to change the global energy matrix increases while alternative energy sources appears as a bet to fulfill the contemporary aspirations for sustainability, and Brazil emerges in a very favorable position, because it has the essential natural conditions to allow this sector s full development. In this perspective, the work has the scope to analyze how the production of alternative energy sources may act in the search for concretization of constitutional values, to promote sustainable development for present and future generations, and to reduce regional and social inequalities in an attempt to improve the quality of life of the population. It will also be observed the current regulatory framework of alternative energy sources in the national laws to verify the existence of legal and institutional security, which is necessary to guarantee the full development of the sector in the country. And to investigate the expected results, it will be observed through the concrete evaluation of specific practices adopted in the industry, analyzing their actual compliance with the constitutional provisions under analysis, based on the examination of the possibility of using renewable biomass sources for biofuel production, promoting development to the country, indicating the opening lines about how this important sector can act to solve the energy challenge today

A evolução do emprego formal industrial nas cidades médias do estado do Ceará (Juazeiro do Norte, Crato e Sobral) no período de 1990 a 2010

The work consists in a discussion of the evolution of formal employment in the industrial cities of Ceará state averages from 1990 to 2010, since this period was marked by important changes. It is emphasized that in order to achieve this aim, the present study was based on a survey of relevant literature on the subject, as well as the use of the Annual Report of Social Information (RAIS), published by the Ministry of Labour and Employment (MTE) and the Brazilian Institute of Geography and Statistics (IBGE). The central question to be considered in this study is how we evolved formal employment industry in medium-sized cities (Juazeiro do Norte, Crato and Sobral) of Ceará? The assumption that guides this work is that given the economic policies of the 1990 and 2000 these policies encouraged the relocation, thus implying significant growth in the formal manufacturing employment in these cities. Regarding the results obtained in the survey, it was found that the industrial sector of these cities, showed considerable dynamism in what refers to the expansion of establishments. When observed in percentage terms medium-sized cities (345.5%) had the highest growth in number of establishments in the 1990s with rates higher than the Northeast region (285.9%) and Brazil (167.5%). The highlight was the city of Juazeiro, with the highest concentration of micro and small footwear companies in the state. Regarding the number of formal jobs created in medium-sized cities, it went from 6.596 in 1990 to 41.660 million formal jobs in 2010, with a growth rate of 532%. The sector contributed most to employment generation was the footwear. Although the levels of minimum wages, the 1990 recorded the lowest levels. In the 2000, there were real gains in levels of minimum wages in all cities, however, it may be noted that over the decades there has been significant momentum. However, this momentum was not enough to prevent the end of the study period CMs-Ceará present low wages

Secagem de misturas de polpa de frutas tropicais em leito de jorro

Drying of fruit pulps in spouted beds of inert particles has been indicated as a viable technique to produce fruit powders. Most of the processes employed to produce dried fruit pulps and juices, such as Foam Mat, encapsulation by co-crystallization and spray drying utilize adjuvant and additives (such as thickeners, coating materials, emulsifiers, acidulants, flavors and dyes), which is not always desirable. The fruit pulp composition exerts an important effect on the fruit powder production using a spouted bed. In the study by Medeiros (2001) it was concluded that lipids, starch and pectin contents play an important role on the process performance, enhancing the powder production; however, the drying of fruit pulps containing high content of reducing sugars (glucose and fructose) is practically unviable. This work has the objective of expanding the studies on drying of fruit pulps in spouted bed with aid of adjuvant (lipids, starch and pectin) aiming to enhance the dryer performance without jeopardizing the sensorial quality of the product. The optimum composition obtained by Medeiros (2001) was the basis for preparing the mixtures of pulps. The mixture formulations included pulps of mango (Mangifera indica), umbu (Spondias tuberosa) and red mombin (Spondia purpurea) with addition of cornstarch, pectin and lipids. Different products were used as lipids source: olive and Brazil nut oils, coconut milk, heavy milk, powder of palm fat and palm olein. First of all, experiments were conducted to define the best formulation of the fruit pulps mixture. This definition was based on the drying performance obtained for each mixture and on the sensorial characteristics of the dry powder. The mixture formulations were submitted to drying at fixed operating conditions of drying and atomizing air flow rate, load of inert particles, temperature and flow rate of the mixture. The best results were obtained with the compositions having powder of palm fat and palm olein in terms of the drying performance and sensorial analysis. Physical and physicochemical characteristics were determined for the dry powders obtained from the mixtures formulations. Solubility and reconstitution time as well as the properties of the product after reconstitution were also evaluated. According to these analyses, the powder from the mixtures formulations presented similar characteristics and compatible quality to those produced in other types of dryers. Considering that the palm olein is produced in Brazil and that it has been used in the food industry substituting the palm fat powder, further studies on drying performance were conducted with the composition that included the palm olein. A complete factorial design of experiments 23, with three repetitions at the central point was conducted to evaluate the effects of the air temperature, feeding flow rate and intermittence time on the responses related to the process performance (powder collection efficiency, material retained in the bed and angle of repose of the inert particles after the process) and to the product quality (mean moisture content, loss of vitamin C and solubility). Powder production was uniform for the majority of the experiments and the higher efficiency with lower retention in the bed (59.2% and 1.8g, respectively) were obtained for the air temperature of 80°C, mixture feed rate of 5ml/min in intervals of 10 min. The statistical analysis of the results showed that the process variables had individual or combined significant influences on the powder collection efficiency, material retention in the bed, powder moisture content and loss of vitamin C. At the experimental ranges of this work, the angle of repose and solubility were not influenced by the operating variables. From the results of the experimental design, statistical models were obtained for the powder moisture content and loss of vitamin C
