Estudos de Durabilidade Frente ao Ataque Ácido de Compósitos Portland-Polímero para Cimentação de Poços de Petróleo

Portland-polymers composites are promising candidates to be used as cementing material in Northeastern oil wells of Brazil containing heavy oils submitted to steam injection. In this way, it is necessary to evaluate its degradation in the commonly acidizind agents. In addition, to identify how aggressive are the different hostile environments it is an important contribution on the decision of the acidic systems to be used in. It was investigated the performance of the Portland-polymer composites using powdered polyurethane, aqueous polyurethane, rubber tire residues and a biopolymer, those were reinforced with polished carbon steel SAE 1045 to make the electrochemical measurements. HCl 15,0 %, HCl 6,0 % + HF 1,5 % (soft mud acid), HCl 12,0 % + HF 3,0 % (regular mud acid) and HAc 10 % + HF 1,5 % were used as degrading environment and electrolytes. The more aggressive acid solution to the plain Portland hardened cement paste was the regular mud acid, that showed loss of weight around 23.0 %, followed by the soft mud acid, the showed 11.0 %, 15.0 % HCl with 7,0 % and, at last the 10.0 % HAc plus HF 1.5 % with just 1.0 %. The powdered polyurethane-composite and the aqueous polyurethane one showed larger durability, with reduction around 87.0 % on the loss of weight in regular mud acid. The acid attack is superficial and it occurs as an action layer, where the degraded layer is responsible for the decrease on the kinetic of the degrading process. This behavior can be seen mainly on the Portland- aqueous polyurethane composite, because the degraded layer is impregnated with chemically modified polymer. The fact of the acid attack does not have influence on the compressive strength or fratography of the samples, in a general way, confirms that theory. The mechanism of the efficiency of the Portland-polymers composites subjected to acid attack is due to decreased porosity and permeability related with the plain Portland paste, minor quantity of Ca+2, element preferentially leached to the acidic solution, wave effect and to substitute part of the degrading bulk for the polymeric one. The electrolyte HAc 10 % + HF 1,5 % was the least aggressive one to the external corrosion of the casing, showing open circuit potentials around +250 mV compared to -130 mV to the simulated pore solution to the first 24 hours immersion. This behavior has been performed for two months at least. Similar corrosion rates were showed between both of the electrolytes, around 0.01 μA.cm-2. Total impedance values, insipient arcs and big polarization resistance capacitive arcs on the Nyquist plots, indicating passivity process, confirm its efficiency. In this way, Portlandpolymers composites are possible solutions to be succeed applied to oilwell cementing concomitant submitted to steam injection and acidizing operation and the HAc 10,0 % + HF 1,5 % is the less aggressive solution to the external corrosion of the casing

Otimização do processo de síntese do aluminato de cobalto via método de polimerização de complexos (MPC) através do planejamento fatorial fracionado

In the ceramics industry are becoming more predominantly inorganic nature pigments. Studies in this area allow you to develop pigments with more advanced properties and qualities to be used in the industrial context. Studies on synthesis and characterization of cobalt aluminate has been widely researched, cobalt aluminate behavior at different temperatures of calcinations, highlighting especially the temperatures of 700, 800 and 900° C that served as a basis in the development of this study, using the method of polymerization of complex (CPM), economic, and this method applied in ceramic pigment synthesis. The procedure was developed from a fractional factorial design 2 (5-2) in order to optimize the process of realization of the cobalt aluminate (CoAl2O4), having as response surfaces the batch analysis data of Uv-vis spectroscopy conducted from the statistic software 7.0, for this were chosen five factors as input variables: citric acid (stoichiometric manner), puff or pyrolysis time (h), temperature (° C), and calcinations (° C/min), at levels determined for this study. By applying statistics in the process of obtaining the CoAl2O4 is possible the study of these factors and which may have greater influence in getting the synthesis. The pigments characterized TG/DSC analyses, and x-ray diffraction (XRD) and scanning electron microscope (SEM/EDS) in order to establish the structural and morphological aspects of pigment CoAl2O4, among the factors studied it were found to statically with increasing calcinations temperature 700°< 800 <900 °C, the bands of Uv-vis decrease with increasing intensity of absorbance and that with increasing time of puff or pyrolysis (h) there is an increase in bands of Uv-vis proportionally, the generated model set for the conditions proposed in this study because the coefficient of determination can explain about 99.9% of the variance (R²), response surfaces generated were satisfactory, so it s possible applicability in the ceramics industry of pigments

Estudos comparativos do ciclo de regeneração de diferentes tipos de silicoaluminofosfatos

Different types of heterogeneous catalysts of the silicoaluminophosphate type, (SAPO-5, SAPO-11, SAPO-31, SAPO-34 and SAPO-41), molecular sieves with a: AFI, AEL, ATO, CHA and AFO structure, respectively, were synthesized through the hydrothermal method. Using sources such as hydrated alumina (pseudobohemita), phosphoric acid, silica gel, water, as well as, different types of organic structural templates, such as: cetyltrimethylammonium bromide (CTMABr), di-isopropylamine (DIPA), di-n- propylamine (DNPA) and tetraethylammonium hydroxide (TEOS), for the respective samples. During the preparation of the silicoaluminophosphates, the crystallization process of the samples occurred at a temperature of approximately 200 ° C, ranging through periods of 18-72 h, when it was possible to obtain pure phases for the SAPOs. The materials were furthermore washed with deionized water, dried and calcined to remove the molecules of the templates. Subsequently the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), absorption spectroscopy in the infrared region (FT-IR), specific surface area and thermal analysis via TG/DTG. The acidic properties were determined using adsorption of n-butylamine followed by programmed termodessorption. These methods revealed that the SAPO samples showed a typically weak to moderate acidity. However, a small amount of strong acid sites was also detected. The deactivation of the catalysts was conducted by artificially coking the samples, followed by n-hexane cracking reactions in a fixed bed with a continuous flow micro-reactor coupled on line to a gas chromatograph. The main products obtained were: ethane, propane, isobutene, n-butane, n-pentane and isopentane. The Vyazovkin (model-free) kinetics method was used to determine the catalysts regeneration and removal of the coke

Estudo da segregação gravitacional do processo de injeção de vapor em reservátórios heterogêneos

Due to reservoirs complexity and significantly large reserves, heavy oil recovery has become one of the major oil industry challenges. Thus, thermal methods have been widely used as a strategic method to improve heavy oil recovery. These methods improve oil displacement through viscosity reduction, enabling oil production in fields which are not considered commercial by conventional recovery methods. Among the thermal processes, steam flooding is the most used today. One consequence in this process is gravity segregation, given by difference between reservoir and injected fluids density. This phenomenon may be influenced by the presence of reservoir heterogeneities. Since most of the studies are carried out in homogeneous reservoirs, more detailed studies of heterogeneities effects in the reservoirs during steam flooding are necessary, since most oil reservoirs are heterogeneous. This paper presents a study of reservoir heterogeneities and their influence in gravity segregation during steam flooding process. In this study some heterogeneous reservoirs with physical characteristics similar those found in the Brazilian Northeast Basin were analyzed. To carry out the simulations, it was used the commercial simulator STARS by CMG (Computer Modeling Group) - version 2007.11. Heterogeneities were modeled with lower permeability layers. Results showed that the presence of low permeability barriers can improve the oil recovery, and reduce the effects of gravity segregation, depending on the location of heterogeneities. The presence of these barriers have also increased the recovered fraction even with the reduction of injected steam rate

Estudo do processo de drenagem gravitacional do óleo assistido com injeção de vapor e solvente

Como os recursos de hidrocarbonetos convencionais estão se esgotando, a crescente demanda mundial por energia impulsiona a indústria do petróleo para desenvolver mais reservatórios não convencionais. Os recursos mundiais de betume e óleo pesado são estimados em 5,6 trilhões de barris, dos quais 80% estão localizados na Venezuela, Canadá e EUA. Um dos métodos para explorar estes hidrocarbonetos é o processo de drenagem gravitacional assistido com injeção de vapor e solvente (ES-SAGD Expanding Solvent Steam Assisted Gravity Drainage). Neste processo são utilizados dois poços horizontais paralelos e situados verticalmente um acima do outro, um produtor na base do reservatório e um injetor de vapor e solvente no topo do reservatório. Este processo é composto por um método térmico (injeção de vapor) e um método miscível (injeção de solvente) com a finalidade de causar a redução das tensões interfaciais e da viscosidade do óleo ou betume. O objetivo deste estudo é analisar a sensibilidade de alguns parâmetros operacionais, tais como: tipo de solvente injetado, qualidade do vapor, distância vertical entre os poços, porcentagem de solvente injetado e vazão de injeção de vapor sobre o fator de recuperação para 5, 10 e 15 anos. Os estudos foram realizados através de simulações concretizadas no módulo STARS (Steam Thermal, and Advanced Processes Reservoir Simulator) do programa da CMG (Computer Modelling Group), versão 2010.10, onde as interações entre os parâmetros operacionais, estudados em um modelo homogêneo com características de reservatórios semelhantes aos encontrados no Nordeste Brasileiro, foram observadas. Os resultados obtidos neste estudo mostraram que os melhores fatores de recuperação ocorreram para níveis máximos do percentual de solvente injetado e da distância vertical entre os poços. Observou-se também que o processo será rentável dependendo do tipo e do valor do solvente injetado

Estudo das propriedades críticas do processo epidêmico por par com difusão de pares

The pair contact process - PCP is a nonequilibrium stochastic model which, like the basic contact process - CP, exhibits a phase transition to an absorbing state. While the absorbing state CP corresponds to a unique configuration (empty lattice), the PCP process infinitely many. Numerical and theoretical studies, nevertheless, indicate that the PCP belongs to the same universality class as the CP (direct percolation class), but with anomalies in the critical spreading dynamics. An infinite number of absorbing configurations arise in the PCP because all process (creation and annihilation) require a nearest-neighbor pair of particles. The diffusive pair contact process - PCPD) was proposed by Grassberger in 1982. But the interest in the problem follows its rediscovery by the Langevin description. On the basis of numerical results and renormalization group arguments, Carlon, Henkel and Schollwöck (2001), suggested that certain critical exponents in the PCPD had values similar to those of the party-conserving - PC class. On the other hand, Hinrichsen (2001), reported simulation results inconsistent with the PC class, and proposed that the PCPD belongs to a new universality class. The controversy regarding the universality of the PCPD remains unresolved. In the PCPD, a nearest-neighbor pair of particles is necessary for the process of creation and annihilation, but the particles to diffuse individually. In this work we study the PCPD with diffusion of pair, in which isolated particles cannot move; a nearest-neighbor pair diffuses as a unit. Using quasistationary simulation, we determined with good precision the critical point and critical exponents for three values of the diffusive probability: D=0.5 and D=0.1. For D=0.5: PC=0.89007(3), β/v=0.252(9), z=1.573(1), =1.10(2), m=1.1758(24). For D=0.1: PC=0.9172(1), β/v=0.252(9), z=1.579(11), =1.11(4), m=1.173(4)

Contribuições sobre estudos térmicos (TG/DTG, DTA, DSC e DSC-Fotovisual) da rifampicina e seus principais produtos de degradação

Since its synthesis over 48 years rifampicin has been extensively studied. The literature reports the characterization of thermal events for rifampicin in nitrogen atmosphere, however, no characterization in synthetic air atmosphere. This paper aims to contribute to the thermal study of rifampicin through thermal (TG / DTG, DTA, DSC and DSC - FOTOVISUAL ) and non-thermal (HPLC, XRPD , IR - FTIR , PCA) and its main degradation products ( rifampicin quinone , rifampicin N-oxide 3- formylrifamicin). Rifampicin study was characterized as polymorph form II from techniques DSC, IR and XRPD. TG curves for rifampicin in synthetic air atmosphere showed higher thermal stability than those in N2, when analyzed Ti and Ea. There was characterized as overlapping events melting and recrystallization under N2 with weight loss in the TG curve, suggesting concomitant decomposition. Images DSCFotovisual showed no fusion event and showed darkening of the sample during analysis. The DTA curve in synthetic air atmosphere was visually different from DTA and DSC curves under N2, suggesting the absence of recrystallization and melting or presence only decomposition. The IV - FTIR analysis along with PCA analysis and HPLC and thermal data suggest that rifampicin for their fusion is concomitant decomposition of the sample in N2 and fusion events and recrystallization do not occur in synthetic air atmosphere. Decomposition products studied in an air atmosphere showed no melting event and presented simultaneously to the decomposition initiation of heating after process loss of water and / or solvent, varying the Ti initiating events. The Coats - Redfern , Madsudhanan , Van Krevelen and Herwitz - Mertzger kinetic parameters for samples , through the methods of OZAWA , in an atmosphere of synthetic air and / or N2 rifampicin proved more stable than its degradation products . The kinetic data showed good correlation between the different models employed. In this way we contribute to obtaining information that may assist studies of pharmaceutical compatibility and stability of substances

Plano de Desenvolvimento da Escola (PDE): o processo de implantação de uma nova proposta de descentralização em duas escolas da rede municipal de ensino de Natal de 1999 a 2002

The 1988 Constitution was the legal marc to define changes in Brazilian State with major importance to the layout of public politician. In that moment of redefinitions e openness to new ways the redemocratization, participation and decentralization of public school had as their starter the elementary school. This work focus on the manage of FUNDESCOLA, particularly one of its politics called PDE (Educational Development Plan) wich purpose is guarantee a better quality in teaching and spread out democracy throughout its methodology. It was chosen two public schools: Professor Ulisses de Góis and Antonio Campos. The theoretical and methodological orientation is based on the theory of participative democracy developed by authors such as Putnam and Pateman. They says that a cultural background precedes individual participation in society. The collected data (educational legislation, surveys with all sectors of schools and technicians of Natal educational secretary, and relevant documents of de institutions) showed that PDE. Implementation had opposite runnings in the schools studied. In one, as a consequence of bad preparations of its teachers to absorve its methodology, PDE failed. In another way, PDE achieved its goals, especially helping the structure of action plans of the school and the administrative organization making possible several pedagogic activities planned. The work concludes that the main factor the failure or success of PDE relies on the organizational (both political and pedagogical) structure of each school. This discovery implies three important guidelines when comes to formulation of public politicians: a) Constitution of school; b) the local actors who manages the actions; c) the colletive interest in taking part of decisions

Alguns aspectos sobre o processo da democratização dos sistemas políticos no mundo árabe :Egito e Líbano como modelos de estudo

The World has tried diverse democratic waves at distinct moments. Some nations have adopted the idea of the democracy for years; others have not yet and other ones are still in a slow process of transition. The field of studies on the Arabian political systems has testified since the last quarter of 20th century a notorious development. This advance disclosed in the existence of a set of trends that has turned around a number of concepts and main theoretical frames such as the political pluralism and the democratic transition and the civil society and its relation with the State. The speech on the process of democratic transition consists in part in the capture and the analysis of the role of the forces and the organizations of the civil society in this process. The peculiarities of the Arab World excite questions concerning the establishment of one governmental system in this universe in the mold of that one that develops with hegemony in the Occident, which has become an interesting field of inquiries for the Political Science. This study comprises the analysis of some aspects of the political situation in the Arab World towards the process of democratization in which Egypt and Lebanon are models of study. Thus the theoretical basis of the term democracy is introduced, presenting different considerations about this expression, since the sprouting of the term until its current conception; later the civil society is analyzed as well as the systems of the political parties and the electoral systems of both countries in attempt to identify the level of democratization existing there and also to find the possible ways to magnify the democratic horizons

O processo avaliativo institucional de desempenho do sistema público municipal de Teresina-PI (2001 a 2005): entre a lógica da excelência e a lógica da aprendizagem

This work focalize the institutional and educational evaluation, aiming to investigate the Municipal System Institutional Evaluation Performance of Teresina City Piauí (2001-2005), and to reflect about Institutional System Performance and its contribution to compose a new learning evaluation practice. In this sense, classifies elements about the evaluation practice in two Elementary Education municipal public schools, involving Education Municipal Bureau technicians as managers, pedagogues, teachers and students. Based on the ethnographic studies principles in the educational area, the work employs investigative procedures like document analysis, interviews with groups and individuals and also participator s comments. Intending to comprehend the complexity produced by the institutional and education evaluation processes, the wok reveals the Institutional Evaluation legal and educational political basis and the several positions assumed by the Learning Evaluation, as a classification tool or as a learning enhancement. This work points, as results, to a evaluation culture bipolarity carried out by the Municipal Education System as a explicit control and regulation toll, related to the classification and learning in a interaction process that operates both in the pressure and the reflection, as a culture practice established between excellence of logic and learning. The evaluation history has been construct on the evaluation actions dialectics, joint simultaneously between the Institutional Evaluation Performance and the learning evaluation. The senses, meanings and actions bipolarity is a interaction process product sustained between the institutional evaluation, under the scholar ranking application, and the learning evaluation. In this relativity, the teacher evaluation practice is found, ruled by interesting, thoughts and actions on the school evaluation, allowing a higher security and support to the learning results. Grounded in the researched reality, its possible to say that the teacher s evaluation practice is diversified, with different characteristics, when it is done in the learning search and in the learning intention. In the first case, reflects, rearranges and constructs new actions that lead the student to produce learning. In the second, shows the will, the wish of learning, but is a weak action, producing a not really significant learning and development; as a result, remains the mark approach as a determinant in the student future. The work s hope is to contribute not just to rethink these two evaluations dimensions the institutional and the learning ones but also to organize the school and to improve the pedagogic process

Estudos da relação entre fromaçãodocente e desenvolvimento do pensamento: redimensionando o olhares

Este trabajo trata de un estudio sobre la relación entre la formación continuada de los profesores y el desarrollo del pensamiento teórico. Es nuestro objetivo comprender la relación entre la formación profesional de los profesores de los años iniciales de la Enseñanza Primaria y el desarrollo de su pensamiento. En términos específicos pretendemos reconstruir los procesos formativos de las profesoras, identificando sus necesidades y los elementos que interfieren en su práctica pedagógica; diagnosticar la fase del desenvolvimiento del pensamiento y dar inicio al proceso formativo de desenvolvimiento del pensamiento; además de analizar la conexión entre ese proceso y la elaboración conceptual, tomando como referencia el concepto de pensamiento. La referencia empírica se constituye de profesoras de la Escuela Municipal Professor Arnaldo Monteiro Natal/RN, que actúan en los grados iniciales de la Enseñanza Primaria y da Educación Infantil. Para desencadenar el proceso investigativo utilizamos como referencial teórico el materialismo histórico-dialéctico como método para análisis de los fenómenos, por entender que a través de esa lógica es que podremos buscar los elementos que nos darán sustentación a una mediación pedagógica que puede posibilitar mayor eficacia en la comprensión de los fenómenos. Recorreremos a pesquisa colaborativa, una vez que es nuestra intención desenvolver una acción investigativa compartida, teniendo en vista buscar medios para resolver los problemas que la práctica pedagógica nos impone. La investigación colaborativa posibilita al sujeto partícipe reflexionar, ser investigador y co-constructor da su práctica. Así, algunos procedimientos metodológicos fueron considerados adecuados para que pudiésemos alcanzar los resultados deseados, como Reuniones, Sondeado Diagnóstica, Ciclos de Estudios Reflexivos, Sesiones Reflexivas y la Autobiografía de Formación. Ni todas las profesoras están en el nivel de elaboración conceptual, en función del proceso vivido a lo largo de nuestras vidas, aún así, toda a trayectoria de la pesquisa posibilitó la descubierta de aspectos significativa sobre nuestro objeto de investigación. Para hacer el análisis de ese proceso nos utilizamos de las teorías de Vigotski, Guetmanova, Kopnin, Rubinstein. Podemos decir que, en la perspectiva de la colaboración, la reflexión sobre la práctica puede desencadenar una nueva mirada del profesor sobre su proceso de formación, el desenvolvimiento de su pensamiento y la acción desarrollada con su alumno. No fue posible verificar, en la práctica, los resultados de nuestro trabajo, ya que, ese no era nuestro objetivo, mas nuestras fallas presentan mudanzas teóricas significativas. Entretanto, resaltamos que las conclusiones a que llegamos están lejos que se acaben , una vez que es un tema complejo, que puede posibilitar el surgimiento de nuevos estudios, de nuevas pesquisas, de nuevos conocimientos

O atendimento educacional especializado no processo de inclusão escolar, na rede municipal de ensino de Mossoró/RN

This dissertation aims to analyze the specialized educational services(AEE, Portuguese) implemented in four municipal schools of Mossoró/RN, with attention to the process of collaboration between regular classroom teachers and multifunctional resource classroom teachers. We use as theoretical reference the works of Vygotsky and others authors that write about education and collaboration. To accomplish the research we chose a qualitative approach, using as a methodological resources: study of cases, bibliographical, documental and field research. For the field research we make observations in regular and multifunctional classrooms. We produce group intervieus with regular and multifunctional teachers. From the analysis performed we identify that the concepts and the practices of teachers in regular classrooms changes, with integrationist predominance. The AEE s teachers had more inclusive conceptions and greater investment in continuing education than the regular classroom teachers. The practices of regular classroom teachers are more traditional, what makes the learning process more difficult for the students, even more for the students with disabilities and pervasive developmental disorders. Teachers of AEE was more interactive and creative, however, the attention to the students was more individual. In three of the four schools surveyed stand out the efforts of the teachers of specialist classroom to collaborate with regular school teachers, by notes, e-mails, phone calls and resource sharing. In one of the four was noted a good collaborative interactive between the AEE teachers and the regular school teachers. The school with the worst improvement was that in which the actions of the teachers of the AEE were limited to actions in multifunctional resource classroom. The resistance to these professionals was identified in the statements of the regular classroom teachers. Another issue raised was the lack of time for teachers to conduct AEE actions that contribute to the process of school students, because their working hours is restricted to the opposite turn in school. Transport difficulties for the students to attend the resource classroom multifunctional and the lack of dialogue with the health sector was challenges for the four schools. The families were with a practically constant interest to interact with the AEE teachers in the four schools. Thus, we believe that the presence of AEE school can make contributions to the educational process, however, it is necessary more attention to the collaborative process between teachers and the school community

Inclusão de estudantes com deficiência nas instituíções de ensino superior da cidade do Natal/RN:análise das condições oferecidas no processo seletivo vestibular

The number of disabled students, who have entered the university, in Brazil, since the beginning of this century, is undergoing a speed growth. It is a change that follows a global trend that spreads an inclusive education policy and that has had a profound impact on Brazil, with import results in field researches. This subject has been highlighted due to the significant amount of disabled students enrolled in college institutions (IES), although it is still modest the number of studies about it, especially in what matters the assistance given to the candidates to a university entrance examination. The aim of this paper is to investigate how effectively Natal s IES apply the rules established in Brazilian law concerning disabled students, especially MEC/GM Circular Warning n. 277/96, in what respects the conditions given to disabled students preparing to enter a college. The investigation followed a qualitative methodological approach with support on an exploratory study. The data recollection employed questionnaire, semi-structured interview and documental analyses, and the data have been organized and assessed following Minayo s (1996) stages. What concerns the results, it was observed that none of the ten colleges inquired confirmed to possess places exclusively to disabled candidates; six of them, however, offer Special Examining Board in the selection process of disabled candidates. Among eighteen college bills, only two of them offered specific information related to services and resources offered by IES to the candidates who ask for especial assistance concerning examination. During the interviews, four managers avowed the preoccupation in offering an equal selection process, but two of them proved not dominate the subject. In conclusion, the investigated institutions managers do not still seem to respect the rule that guarantees to disabled candidates equal conditions during all the process of the university entrance examination. With this work, we hope do help changing this focus and contribute to new studies on disabled persons studying for a degree

A coordenação pedagógica e o processo de inclusão do aluno com necessidade educacionais especiais:Um estudo de caso

The school inclusion presents a number of challenges that has been mobilizing initiatives and studies about its effectiveness. If on one hand in such studies and initiatives it becomes important to emphasize on the role and training of teachers, on the other, there is few studies about the role (and performance) of the pedagogical coordination in face of this process. In this sense, this research focuses on the role of educational coordination in face of the school inclusion of students with Special Educational Needs (SEN) and it undertakes the following study s questions: has the action by the coordinator contributed to the process of including students with Special Educational Needs? How is it presented in the process of inclusion of students with SEN in regular education? And it aims to: investigate the role of the pedagogical coordinator in the process of inclusion of students with Special Educational Needs of Primary Education at regular schools; and to analyze the limits and possibilities of the coordinator actions in the process of inclusion of students with SEN. For the effectiveness of the research, a state school of Elementary School located at the city of Natal/RN was taken as an empiric field. It was selected as research subjects 4 coordinators, 2 teachers of the Multifunctional Resources Room and 2 teachers of 6th to 9th grades. The methodological approach that was used in this research is consistent with the qualitative approach, and it is configured as a case study, as it is understood that this type of research responds to the objective of the study, assuming the observation of everyday school life, the educational document analysis and interviews with the subjects as procedures and tools to build data. The construction and analysis of the data were followed by a dialogue with the literature dedicated to coordinating education and school enrollment. Considering the responsibilities of the contemporary pedagogical coordination due to the challenges and possibilities of schooling for all students, specially regarding to what is referred as collaborative work and ongoing training of teachers, this study points out to the lack of an articulated action related to the school inclusion process, considering the monitoring of the teaching activity and its dialogue with the Multifunctional Resources Room. Moreover, the emphasis on meeting the daily school routines and the compliance with bureaucratic procedures, put it into second, restructuring of the Political-Pedagogical and the possibility of mobilization of school around the problematization and systematization of an inclusive school project. The effectiveness of school s inclusion, therefore, implies the scaling of the functions of the pedagogical coordination, as well as the reorganization of the school it self, to ensure the mediation of collaborative actions, contemplating the teachers continuing education, having as a landmark difficulties, problems and experiences constructed in the school context

O processo de cuidar em Unidade de Terapia Intensiva

The environment of Intensive Care Unit (ICU) is commonly referred to as a place where caring is inextricably linked to high technology. The care in ICU often changes the patient into a taxpayer being left apart from its complexity and sometimes seen through a reductionist perspective. Thus, studies circa the care process are needed oriented from a historical ransom, raising the prospect of a more centralized human care. Hence, this study aimed to analyze the care process in a nursing intensive care unit from the perspective of the professional, family and patients. The study is characterized from a qualitative, descriptive and exploratory methodological approach. The actors were participating nursing professionals, patients and family members of an intensive care unit of Mossoró / RN. Data were collected in the period of May-June 2011, through interviews and observation of activities performed by nursing professionals, and their records in the chart. Data analysis was divided into topics and subtopics representing the phases and shapes that formed the collection. The analysis and discussion of the interviews were based on Bardin's proposal, when we created categories from a process of sorting and grouping criteria adequately defined. The observation of nursing records intended to observe the emphasis which is described in those notes as well as their consistency with practice of FCN and resolution 358/2009. The analysis showed that the nursing staff also performs work focused on mechanized activities and technical-bureaucratic institution that seem to override the needs of patients. In an overview, the care provided by professionals occurs either fragmented or insipient, however there is a service that involves other aspects beyond technical-curative practice, considering that major attention is given to the family and patient, focused on the concern of Nursing guiding their actions in not only the performance of procedures. However, the process of humanizing not always ends with an engagement between professional and patient, which mischaracterizes the true meaning of human care. The records also showed a tendency to focus on caring in a positivist line, where, in most cases, the factors of the disease and the obligation to meet the productivity have overshadowed other relevant aspects to a holistic understanding of caring. Regarding FCN Resolution No. 358/2009, which guides a systematization of nursing care, it is confirmed a technical view, a fragmented and superficial view of the patient, as well as a weakness of care, caused by ignorance and unpreparedness of the entire team. The perspective of caring demonstrates a reality with dialectic between what is proposed in a humane nursing and what happens in this performance space. Besides, it was shown a daily full of important considerations that arise in professional practice, in their views and also those people who were participants in the process
