É no interior das relações sociais capitalistas que situamos e buscamos compreender a Formação e a Prática do Educador. Marcadas pelas contradições inerentes às relações de dominação, a Formação e a Prática do Educador refletem e expressam essas contradições. Assim, a formação que o educador recebe e a prática que ele desenvolve como trabalhador da educação, ao mesmo temoo em que reproduzem as relações de dominação, podem contribuir para a transformação dessas relações. Partindo deste pressuposto, o nosso trabalho propõe uma reflexão sobre a interferência da formação do educador na sua prática diária junto às classes populares. A suposição de que o instrumental teórico/metodológico veiculado pelos cursos de formação pouco contribui para o educador desenvolver e analisar a sua prática junto às classes populares e de que, assim, pode contribuir para o fracasso escolar dessas crianças foi trabalhada, tendo como base de informações a experiência de dois projetos educativos. Um deles envolve o Curso de Pedagogia da Universidade Santa Ursula, e o outro, o "MEC/USU", integrando a Universidade e escolas públicas de 1o grau no Município do Rio de Janeiro. O processo de análise nos permitiu, por um lado, concluir que existe uma coerência, unificada pela ideologia do sistema, entre o tipo de formação alienada e diluída dos educadores e sua prática junto as classes populares, evidenciando que esta formação e esta prática contribuem para a reprodução do "status quo". Por outro lado, constatamos a presença de elementos indicadores de postura critica, o que revela a existência de contradições no interior do curso de Pedagogia e das escolas de 1o grau, demonstrando a possibilidade de a Formação e a Prática do Educador contribuir para as transformações educacionais, sociais, politicas, econômicas e culturais no bojo das contradições do processo histórico, na medida em que estes indicadores forem trabalhados e reforçados.

The present inquiry has as main objective to understand the process of formation of the international strategies of the exporting companies of fruits of the RN through the theory of the resource dependence. Aiming at to clarify as the companies they can carry through the process of internationalization through this theory had been study the behavior and economic theories of the process of internationalization of companies. Amongst the economic theories they are distinguished the eclectic paradigm of Dunning (1958), Vernon (1669) through the theory of the cycle of the product and Bucley and Casson (1979) with the theory of the international operations. In the mannering boarding they had been investigated the school of Upsala through Johanson and Valnhe (1977) with the concept of the increasing of the markets and in the distance psychic starts and the interaction of the purchaser-salesman of Hallen and Wiedersheim-Paul (1979). In this perspective it observes main the occured changes in the organization in function of this process, following the rules observed by the gradual ingression in the international market, having as base ways of entrances in the external market used by these companies, in view of the frist phase that the company presents of businesses. Ahead of you analyze of these theories the study searches to analyze the convergence of the concepts proclaimed for the theory of the dependence of resources (PFEFFER; SALANCIK, 1978). and strategies of internationalization of the companies. The research is characterized as qualitative case study which adopts and exploratory and analytical type, retrospective matrix. The adopted strategy is of case study and the unit of analysis consisting of the Finobrasa, pertaining company to the Vicunha Group. The main method of collection of data was halfstructuralized interview allied the documentary research that together had presented an empirical perspective of the internationalization process. The analysis and quarrel of the results understand the description and the interpretation of the one of the information through the technique of analyzes of content. Initially the historical of the exportation of fruits of the Rio Grande do Norte with the focus in the region Açu/Mossoró is presented and after that the information of the Finobrasa are presented as base of the study. The main events are identified that had constituted the phases of the strategical model of the company. It was observed that the dimensions most excellent amongst those proclaimed by the School of Uppsala had been the learning, staffs and the step-starts is sufficiently gifts in the reality of the company, as well as the aspects of strategical alliances since the consolidated relationship of the Vicunha Group create a more solid trajectory in the international market allied the conditions created windows of marked . One understands, therefore, that the investigated process still has base the theoretical theories of the internationalization strategies corroborating for the theoretical convergence of the rules proclaimed for the theory of the dependence of resources.

This dissertation sutdies the mediative function in the planning of literary text reading classes of Portuguese. Its main central focus proposes that planning favors the pedagogical reading work of literary texts in the teaching of Portuguese, for they are regarded as one of the mediative elements the teaching-learning process. It also allows for its subjects to rethink the practice, theorizing it. As a theoretical basis the studies on participative planning are used, especially the studies concerning dialogic planning. The language/literature teaching perspective adopted in this work is guided by the socio-interactive conception of language, in a way that reading is seen as a comprehensive and interactive activity. Given the research process, the analysis of the reading process involved the Reader s Response, once that this theory considers the role of the reader and her/his interaction with the text. The study is grounded upon the following research question: which role(s) does the pedagogical planning play as a mediator of the reading teaching-learning process? The main objective of this dissertation is to investigate the pedagogical planning activity as a mediative instrument in the practice of reading in the Portuguese classes. The study is constituted of three stages, the third being emphasized (2002/2005) in which the direction of the participative action-research was used, as a way of acknowledging the pedagogical role in the teaching plan, as an instrument capable of rendering reorganization in the teaching-learning process of reading classes. We have as participants teachers of Portuguese in the elementary school (Ensino Fundamental, 3º ciclo), besides other segments of public schools, in the city of Pau dos Ferros RN, in which the previous studies were developed. The results point to the relevance in the role of the teacher, as a more experienced reader, in developing of pedagogical strategies that may come to favor the teaching of reading, having in the pedagogical sphere an instrument of theoretical reflection and sistematization of activities to be implemented in the classroom. The conclusions highlight the class plan as the mediative instrument to be incorporated and internalized into the teaching practice, amplifying and modifying the teacher s intervention forms, favoring, thus, her/his pedagogical mediation

The present study analyzes the conceptions and the nursing workers' practices about the relationship between vaccination and biosecurity in a public hospital of reference in communicable diseases in Natal/RN. It is treated, therefore, of a exploratory/descriptive study with qualitative and quantitative approach. They were constituted as collaborators of the research twenty-two nursing professionals, being five nurses, three auxiliary and fourteen technicians in nursing. The information were obtained through the interview technique with semi-structured route. In the quantitative approach, the information were analyzed by statistics and presented in form of tables and graphs to characterize the workers and the aspects related to the vaccination situation of the same ones; and in the qualitative approach, we used the method of content analysis. The analysis was accomplished starting from the categories empiric coming from the process of analysis of the field material, measure through inferences and interpretations based on the authors studied in the theoretical referential of the research. Starting from the analysis of the results, we verified that the nursing interviewees' workers establish in a clear way and it aims at, in your speeches, a direct relationship between vaccination and biosecurity besides attributing a meaning of great importance with relationship to the use of the vaccines in your professional lives in what refers to the control and decrease of the risks, above all the biological ones, to the which are exposed in the daily exercise of your functions. However, when analyzing those workers' vaccination situation, we verified that the vaccination covering still meets on this side of the expected for the vaccines of occupational interest, with prominence just for the vaccines against diphtheria and tetanus and to against hepatitis B, that presented coverings considered very good and above the national average. Considering that the institution, although has a service of health occupational active and offer some vaccines of occupational interest, it still presents a work of little mobilization in what refers to the consciousness and the workers' permanent education with relationship to the need and importance of the occupational vaccination, not only for your workers' protection, as well as measure in the infection control and, therefore, as safety for your patients/clients. We understood that that work type didn't still become politics guided by ministries of Health or of the Labor, however, it falls to the institutions that work for the interest of the workers' health to struggle for all and any action and mobilization that have as objective protects the workers of the risks in your work atmosphere

With the increase of asphalt milling services was also a significant increase in recycling services pavements. The techniques used today are basically physical processes in which the milled material is incorporated into new asphalt mixtures or executed on site, with the addition of virgin asphalt and rejuvenating agent. In this paper seeks to analyze the efficiency of extraction of CAP (Petroleum Asphalt Cement) mixtures from asphalt milling, using commercial solvents and microemulsions. The solvents were evaluated for their ability to solubilize asphalt using an extractor reflux-type apparatus. Pseudoternary diagrams were developed for the preparation of microemulsion O/W surfactant using a low-cost coconut oil saponified (OCS). Microemulsions were used to extract the CAP of asphalt through physicochemical process cold. Analysis was performed concentration of CAP in solution by spectroscopy. The data provided in the analysis of concentration by the absorbance of the solution as the basis for calculating the percentage of extraction and the mass flow of the CAP in the solution. The results showed that microemulsions prepared with low concentration of kerosene and butanol/OCS binary has high extraction power of CAP and its efficiency was higher than pure kerosene, reaching 95% rate of extraction

A chemical process optimization and control is strongly correlated with the quantity of information can be obtained from the system. In biotechnological processes, where the transforming agent is a cell, many variables can interfere in the process, leading to changes in the microorganism metabolism and affecting the quantity and quality of final product. Therefore, the continuously monitoring of the variables that interfere in the bioprocess, is crucial to be able to act on certain variables of the system, keeping it under desirable operational conditions and control. In general, during a fermentation process, the analysis of important parameters such as substrate, product and cells concentration, is done off-line, requiring sampling, pretreatment and analytical procedures. Therefore, this steps require a significant run time and the use of high purity chemical reagents to be done. In order to implement a real time monitoring system for a benchtop bioreactor, these study was conducted in two steps: (i) The development of a software that presents a communication interface between bioreactor and computer based on data acquisition and process variables data recording, that are pH, temperature, dissolved oxygen, level, foam level, agitation frequency and the input setpoints of the operational parameters of the bioreactor control unit; (ii) The development of an analytical method using near-infrared spectroscopy (NIRS) in order to enable substrate, products and cells concentration monitoring during a fermentation process for ethanol production using the yeast Saccharomyces cerevisiae. Three fermentation runs were conducted (F1, F2 and F3) that were monitored by NIRS and subsequent sampling for analytical characterization. The data obtained were used for calibration and validation, where pre-treatments combined or not with smoothing filters were applied to spectrum data. The most satisfactory results were obtained when the calibration models were constructed from real samples of culture medium removed from the fermentation assays F1, F2 and F3, showing that the analytical method based on NIRS can be used as a fast and effective method to quantify cells, substrate and products concentration what enables the implementation of insitu real time monitoring of fermentation processes

Chemokines are important chemotactic cytokines that play a fundamental role in the trafficking of leukocytes to sites of inflammation. They are also potent cell-activating factors, inducing cytokine and histamine release and free radical production, a fact that makes them particularly important in the pathogenesis of allergic inflammation. The action of chemokines is regulated at the level of agonist production and processing as well as at the level of receptor expression and coupling. Therefore, an analysis of the ligands must necessarily consider receptors. Eosinophils are target cells involved in the allergic inflammatory response since they are able to release a wide variety of mediators including CC and CXC chemokines and express their receptors. These mediators could damage the airway epithelial cells and might be important to stimulate other cells inducing an amplification of the allergic response. This review focuses on recently emerging data pertaining to the importance of chemokines and chemokine receptors in promoting eosinophil activation and migration during the allergic inflammatory process. The analysis of the function of eosinophils and their chemokine receptors during allergic inflammation might be a good approach to understanding the determinants of asthma severity and to developing novel therapies.

Paracoccidioides brasiliensis is a fungal human pathogen with a wide distribution in Latin America. It causes paracoccidioidomycosis, the most widespread systemic mycosis in Latin America. Although gene expression in P. brasiliensis had been studied, little is known about the genome sequences expressed by this species during the infection process. To better understand the infection process, 4934 expressed sequence tags (ESTs) derived from a non-normalized cDNA library from P. brasiliensis (isolate Pb01) yeast-phase cells recovered from the livers of infected mice were annotated and clustered to a UniGene (clusters containing sequences that represent a unique gene) set with 1602 members. A large-scale comparative analysis was performed between the UniGene sequences of P. brasiliensis yeast-phase cells recovered from infected mice and a database constructed with sequences of the yeast-phase and mycelium transcriptome (isolate Pb01) (https://dna.biomol.unb.br/Pb/), as well as with all public ESTs available at GenBank, including sequences of the P. brasiliensis yeast-phase transcriptome (isolate Pb18) (http:// www.ncbi.nlm.nih.gov/). The focus was on the overexpressed and novel genes. From the total, 3184 ESTs (64.53%) were also present in the previously described transcriptome of yeast-form and mycelium cells obtained from in vitro cultures (https://dna.biomol.unb.br/Pb/) and of those, 1172 ESTs (23.75% of the described sequences) represented transcripts overexpressed during the infection process. Comparative analysis identified 1750 ESTs (35.47% of the total), comprising 649 UniGene sequences representing novel transcripts of P. brasiliensis, not previously described for this isolate or for other isolates in public databases. KEGG pathway mapping showed that the novel and overexpressed transcripts represented standard metabolic pathways, including glycolysis, amino acid biosynthesis, lipid and sterol metabolism. The unique and divergent representation of transcripts in the cDNA library of yeast cells recovered from infected mice suggests differential gene expression in response to the host milieu.

Several methods have been proposed for calculations of the eccentricity function for a high value of the eccentricity, however they cannot be used when the high degree and order coefficients of gravity fields are taken into account. The method proposed by Wnuk(1) is numerically stable in this case, but when is used. a large number of terms occurs in formulas for geopotential perturbations. In this paper we propose an application of expansions of some functions of the eccentric anomaly E as well as Hansen coefficients in power series of (e - e*), where e* is a fixed value of the eccentricity derived by da Silva Fernandes(2,3,4). These series are convergent for all e < 1.

The non-ohmic properties of the 98.90% SnO2+(1-x)%CoO+0.05% Cr2O3+0.05% Nb2O5+x% MnO2 varistor system (all of them in mol %), as well as the influence of the oxidizing and reducing atmosphere on this system were studied in this work. Experimental evidence indicates that the electrical properties of the varistor depend on the defects that occur at the grain boundary and on the adsorbed oxygen species such as O''(2), O'(2), O in this region. Thermal treatments at 900 degreesC in oxygen and nitrogen atmospheres indicated such a dependence with the values of the non-linearity coefficient (alpha) increasing under oxygen atmosphere, being reduced in nitrogen atmosphere and restored after a new treatment in oxygen atmosphere, presenting a reversibility in the process. EDS analysis accomplished by SEM showed the distribution of the oxides in the varistor matrix. (C) 2002 Kluwer Academic Publishers.

Good optical quality Eu3+-doped silica-polyethyleneglycol hybrids were prepared by the sol-gel process. Thermomechanical analysis showed an increase of the glass transition temperature, due to the stiffness of the polymeric network, as the amount of Eu3+ increased. Europium luminescent properties were used to study structural evolution during the sol-gel transition. For lower doping concentrations dried gels present statistical distributions of Eu3+, typical of an amorphous environment, while for higher concentrations a crystalline-like environment of Eu3+ was observed. A broad emission band was observed in the visible part of the electromagnetic spectrum and assigned to the intrinsic emission from the hybrid polymeric network.

This work describes the synthesis and characterization of 2-aminothiazole modified silica gel (SiAT), and the results of a study of the adsorption and pre-concentration (in batch and using a flow-injection system coupled to an absorption atomic spectrometer) of Cu(II), Ni(II) and Pb(II) in aqueous medium. The adsorption capacities for each metal ions in mmol g -1 were: Cu(II)= 1.18, Ni(II)= 1.15 and Pb(II)= 1.10. The results obtained in the flow experiments showed a recovery of practically 100% of the metal ions adsorbed in a mini-column packed with 100 mg of SiAT, using 100 μL of 2.0 mol L -1 HCl solution as eluent. The sorption-desorption of the metal ions made possible the application of a flow-injection system for the pre-concentration and quantification by FAAS of metal ions at trace level in natural water samples digested and not digest by an oxidizing UV photolysis.
