Os saberes em potencial da atividade policial ostensiva: sistematizando modelos a partir da experiência potiguar

This work of research presents an investigation into the knowledge related to the ostensive policing activities of a group of the Rio Grande do Norte State Military Police Captains. This knowledge, which is decisive and part of Brazilian Military Police Constitutional matters, must be taken into consideration when it comes down to planning and putting into force the services related to ostensive public security. Thus, a historical and social analysis about the formation of the police by starting from foreigner experiences down to Rio Grande do Norte s reality, led by such knowledge, was made. Further, studying Brazilian and local scene, this knowledge was analyzed on the ostensive policing activities as for the principles of the Brazilian National Public Security Plan, Brazilian Classification of Occupations / CBO 2002, the reference documents and studies for police graduation Curricular Basis and Matrix; the Variables of Ostensive Policing, as well as some important competences of police service. Arguing that this knowledge is somehow related to what is presented in this work as Orientation Axis to Military Police Service , research tools such as Critical Case Solution and the answers to the Questionnaire on Fundamental Areas of Military Police Service , having in the end six knowledge models related to ostensive policing activities were used within that group. This knowledge can be classified in three distinct categories of connotations within the military police activity: one with reactive/repressive characteristics being the most predominant; the second as preventive; and another one that revealed that the military police activity is being misused for actions and/or missions outside the scope of action of military police

Segurança das condições de aplicação de herbicidas com aerobarco em plantas daninhas aquáticas no lago da Hidrelétrica de Jupiá

Os objetivos deste trabalho foram quantificar as exposições dérmicas (EDs) e respiratórias (ERs) proporcionadas ao piloto e ao seu ajudante nas aplicações de herbicidas para o controle de plantas daninhas aquáticas com aerobarco; classificar essas condições de trabalho em seguras ou inseguras; e calcular a necessidade de controle das exposições (NCE) e o tempo de trabalho seguro (TTS). O aerobarco utilizado tinha casco de alumínio (4,85 x 2,42 m) e acionamento por hélice acoplada a motor a gasolina de 350 HP. O equipamento de pulverização era composto por bomba de diafragma com fluxo máximo de 49,69 L min-1, pressão máxima de 25 kg cm-2, acionada por motor a gasolina de 4 HP, e tanque de calda de 189 L. A barra de pulverização de alumínio era composta de duas seções laterais de 3 m, posicionadas na linha entre o encosto do banco do piloto e o início da estrutura protetora da hélice. Cada seção da barra tinha seis bicos com pontas de jato plano com indução de ar AI 100 03, espaçados de 0,5 m, e uma ponta OC 20 fixada em cada extremidade. O conjunto de pontas pulverizava faixas de 6 m de largura e aplicava o volume de calda de 200 L ha-1. O sistema tinha gerenciador de fluxo, controlado por central eletrônica acoplada a DGPS (com precisão submétrica), para corrigir automaticamente a vazão em função de alterações na velocidade real da embarcação. As EDs e ERs aos herbicidas foram calculadas com os dados substitutos das exposições às caldas, avaliadas com os traçadores cobre e manganês adicionados às caldas. As exposições foram extrapoladas para uma jornada de trabalho de seis horas. A segurança das condições de trabalho foi determinada com o cálculo da margem de segurança (MS), utilizando-se a fórmula MS = (NOEL x 70)/(QAE x 10), em que QAE = quantidade absorvível da exposição. As condições de trabalho foram classificadas em seguras, se MS>1, ou inseguras, se MS<1. As exposições proporcionadas pelas condições de trabalho foram de 10,65 mL de calda por dia para o piloto e de 16,80 mL por dia para o ajudante, que fica sentado em uma cadeira a 2,0 m à frente do piloto e da barra de pulverização. Classificaram-se como seguras as aplicações dos herbicidas glyphosate (Rodeo, 6 L ha-1), 2,4D (DMA 806 BR, 8 L ha-1) e fluridone (Sonar AQ, 0,4 L ha-1), para o piloto e o seu ajudante. Classificou-se como insegura a aplicação do herbicida diquat (Reward, 4,0 L ha-1) para as duas condições de trabalho, cujas necessidades de controle das exposições calculadas foram de 65% para o piloto e de 78% para o ajudante do piloto.

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

Com a associação da cabina, também são seguras para o tratorista a aplicação do ethoxysulfuron com as pontas TF e a do metribuzin e s-metalochlor com as pontas TTI.

Efeitos do período e volume de aplicação na segurança dos tratoristas aplicando herbicidas na cultura de cana-de-açúcar (Saccharum spp.)

O objetivo deste trabalho foi avaliar os efeitos do período e volume de aplicação na segurança da atividade de tratoristas aplicando herbicidas na cultura de cana-de-açúcar com o pulverizador de barra montado em trator e a eficiência de equipamentos de proteção individual (EPIs) e de uma cabina acoplada ao trator. As exposições dérmicas de 13 condições de trabalho foram avaliadas e analisadas estatisticamente por meio do delineamento inteiramente ao acaso e do esquema fatorial 3 x 2 x 2 + 1. O fator A foi a condição de exposição: 1) exposição dérmica potencial (EDP) - sem nenhuma medida de segurança; 2) exposição com cabina no trator (Cabina); e 3) exposição com as vestimentas (EPI). O fator B foi o volume de aplicação: 1) 200 L ha-1 e 2) 100 L ha-1; e o fator C foi o período de aplicação: 1) diurno e 2) noturno. Como testemunha foi avaliada a EDP do tratorista aplicando na atividade usual de 300 L de calda ha-1, no período diurno. As exposições dérmicas (EDs) aos herbicidas considerados nessas condições de trabalho foram estimadas por meio de dados substitutos das EDs avaliadas ao cátion Cu+2 adicionado como traçador nas caldas aplicadas. O pulverizador utilizado foi do modelo PJ 600, com barra de 12 m de comprimento e 24 bicos de jato plano TT 110 04 ou TT 110 02. As 13 condições de trabalho avaliadas foram classificadas como seguras (MS>1) para o tratorista aplicando os herbicidas glyphosate (48% i.a.), MSMA (48%), diuron (46,8%) + hexazinone (13,2%), clomazone (50%), sulfentrazone (50%), ametryne (50%), diuron (50%), isoxaflutole (75%), metribuzin (48%), 2,4-D (80,6%), ametryne (30%) + clomazone (20%), ametryne (73,25%) + trifloxysulfuron (1,85%) e tebuthiuron (80 %) e inseguras para o herbicida atrazine (50%), nos dois períodos e nos três volumes de aplicação, e ametryne (50%), na aplicação diurna e 100 L de calda ha-1. As aplicações noturnas e os volumes de aplicação reduzidos tornaram as condições de trabalho mais seguras, exceto para o atrazine. A eficiência dos EPIs para a aplicação de 300 L ha-1 variou de 69,5 a 89,3%, e a da cabina do trator variou entre 76,4 e 83,3%, em relação aos volumes reduzidos de 100 e 200 L ha-1.

Avaliação de equipamentos de aplicação de herbicidas em operação de repasse em cana-de-açúcar e segurança para o trabalhador

Objetivou-se com este trabalho classificar em seguras ou inseguras as condições de trabalho de aplicação da formulação comercial de paraquat a 0,5% e de abastecimento dos tanques em operação de repasse em cultura de cana-de-açúcar com os pulverizadores costal manual, costal pressurizado e Pulmipur manual; determinar o efeito das variações na operação de repasse em quatro usinas de açúcar e álcool com o pulverizador costal pressurizado sobre as exposições dos trabalhadores ao paraquat; determinar a eficácia de equipamentos de proteção individual nessas condições de trabalho; e avaliar a intensidade da deriva e a eficácia de acessórios protetores de deriva. As exposições dérmicas e respiratórias dos trabalhadores foram avaliadas e utilizadas para calcular a margem de segurança (MS). Os valores de MS foram utilizados para classificar essas condições de trabalho em seguras (MS > 1) ou em inseguras (MS < 1). Para avaliar a deriva das aplicações na cultura e a eficácia dos protetores de deriva, foram estudados os tratamentos: formulação comercial de paraquat a 0,5% na calda, aplicada com o costal manual, sem e com o chapéu de proteção de deriva; com o costal pressurizado, sem e com a planilha de proteção de deriva; formulação comercial de paraquat pura com o Pulmipur; formulação comercial de glyphosate a 1% com o costal pressurizado e com a planilha, e puro com o Pulmipur; e testemunha sem aplicação. As duas atividades com o Pulmipur proporcionam as maiores exposições dérmicas, devido ao manuseio da formulação, e são inseguras sem o uso dos EPIs e seguras com estes. As atividades com o pulverizador costal manual ou pressurizado são seguras com ou sem os EPIs. As grandes diferenças nas EDs dos trabalhadores se devem às diferenças no tempo de trabalho diário e no número de trabalhadores nas equipes entre as usinas de açúcar e álcool. O protetor de deriva tipo chapéu é eficaz no controle da deriva na aplicação do paraquat, e a planilha, não.

Estudos biológicos de cochonilhas do gênero Planococcus (Hemiptera: Pseudococcidae) em diferentes hospedeiros

This work was carried out to study the development of populations of the genus Planococcus in different plant species, aiming at the verification of host specificity. The mealybugs Planococcus minor were obtained from cocoa plants (Theobroma cacao L.) and coffee crop (Coffea canephora L.), and Planococcus citri from citrus seedlings (Citrus sinensis L. Osbeck). Single eggs were transferred to Petri dishes containing leaf discs of cocoa (T. cacao cultivar Catongo), coffee (Coffea arabica L. cultivar Mundo Novo) and citrus (C. sinensis cultivar Pera Rio). They were maintained on a water-agar slide at 1%, with the abaxial surface turned upwards. The dishes were sealed with a PVC plastic film and kept in climatized chambers regulated at 25 [plus or minus] 1[degrees] C, 70 [plus or minus] 10% RH and 12 hours of photophase. For the mealybugs coming from cocoa plants, the citrus substrate prolonged the nymphal development of the males (26.0 days). In the nymphal period of females and males coming from coffee plants, the coffee substrate allowed a shorter duration of that period (19.2 and 21.3 days, respectively) and, in addition to having providing a longer longevity to the females (59.1 days). The highest rates of mortality were obtained when they were reared on the cocoa substrate, regardless of the host plant from which they were originally collected, and when kept on citrus, for insects collected on coffee plants. P. citri and P. minor have higher preference for coffee substrate regardless of the original host, thus showing partial host specificity.

Métodos não-invasivos para análises hormonais aplicadas aos estudos de ecologia e etologia

O monitoramento endócrino pela mensuração de metabólitos urinários e fecais de hormônios esteróides tem se mostrado uma alternativa viável na investigação da fisiologia reprodutiva e do estresse em uma grande variedade de aves e mamíferos, domésticos e selvagens. Esta abordagem tem contribuído para uma maior integração da endocrinologia com estudos comportamentais e ecológicos, gerando informações mais detalhadas em diversas áreas tais como bem-estar animal, comportamento social, reprodução, biologia da conservação, biomedicina, entre outros. Todavia, o emprego desta metodologia no Brasil tem sido limitado principalmente à pesquisa de parâmetros reprodutivos e de estresse em espécies selvagens, não havendo até o momento trabalhos publicados utilizando a quantificação urinária ou fecal de glucocorticóides ou esteróides sexuais em animais domésticos. Desta forma, esta palestra tem como objetivo ilustrar alguns exemplos de estudos conduzidos no país envolvendo técnicas de monitoramento endócrino não-invasivo, assim como expor possíveis áreas de aplicação desta ferramenta em pesquisas com espécies domesticas.

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

Acesso e permanência na universidade federal do rio grande do Norte sob o ponto de vista do docente e do estudante com deficiência Natal-RN

Inclusion of students with disabilities is a recent case that has been discussed in school contexts, but the current policy of inclusion for access and retention of students in higher education is still a problem face there is much to do, therefore, are incipient studies in which this student body is involved. Accordingly, what is happening is that the most studies deal with on these students and little is said about them. For inclusive education thus the institution should prepare to receive students, having as one of its premises their point of views about what actually experience aiming at promoting education for all. Therefore, this study deals with the process of inclusion of students with disabilities regularly enrolled in undergraduate courses at the Universidade Federal do Rio Grande do Norte - UFRN.They were used the assumptions of qualitative research enabled by the case study method and semi-structured interviews. It has been analyzed by guiding actions and teaching practices, under the views of disabled students and teachers, the conditions of access and permanence offered by UFRN. Twelve students with physical, visual, hearing disabilities participated and five teachers from the acedemic centers that in academic year 2008 taught to these students. For data analysis it was used the technique of content analysis. It was extracted two themes: access and retention of students with disabilities in UFRN, in which emerged the categories described and analyzed in the course of this work. The results show the difficulties of access and retention of students with disabilities within the UFRN, such as attitudinal, pedagogical and architectural barriers. However, as it has also turned out, initial advances in the quest for achieving more effective actions to guarantee access and permanence of these students in UFRN. It has concluded that the scope for the exercise of citizenship in the pupils with disabilities who need this Higher Education Institution has an inclusive education Project, wide and consolidated, for the actions undertaken by the Ministry of Education - MEC, by itself, are not guaranteed to all students due to mobility, autonomy and security. It has hoped this work will bring benefits for new studies to develop features that were located, but were not our focus, because then the UFRN may advance the inclusive process of disabled students

Biossegurança e a saúde do trabalhador na assistência a pacientes em tratamento onco-hematológico

In recent years, the biosafety has been made possible a new look which are based the conceptions of health and illness process, as well as human needs. This new vision is focused on health vigilance that is referenced specifically in this study to the worker s health. The health of workers is essential for the prevention and control of epidemics and outbreaks of diseases as well as emerging and reemerging diseases. The present study wants to show the importance of biosafety measures for health workers, showing them through the concepts in their daily work. It is also to direct the use of biosafety measures in the care of oncology and hematology patients care, because of its infection susceptibility. OBJECTIVES: To analyze the conceptions of health workers in the biosafety pratice to the patients in oncological and hematological treatment in an oncological institution in Natal / RN, as well as make a socio-demographic profile of these workers and to know their difficulties to adequate biosafety measures. METODOLOGIA: The research is exploratory descriptive with qualitative approach, using the technique of oral history. The use of this technique is justified for the possibility of analyze the conceptions of health workers in the face of biosafety measures. From the definition of analysis categories that have emerged in the study. The categories were: daily work, education, occupational risk and onco-hematological care. The research population was the health workers who provide care to patients in oncological and hematological treatment. The study was conducted in the League against Cancer, in Natal / RN, specifically in the unit Luiz Antonio Hospital. Data collections were conducted from June to August of 2011 and were interviewed sixteen employees who assist in oncology and hematology. Structured interviews were conducted in three shifts, given the prospects of expanding the possibilities of analysis of the biosafety concepts. After data collection, the interviews were analyzed qualitatively by the technique of oral history. This genre, thematic oral history is a modern resource used for preparation of documents, files and studies concerning the social experience of people and groups with the construction of a script prior to the interview moment (MEIHY, 2002). ANALYSIS OF INFORMATION: It was made a reflection about the concepts and practices of professionals who take care of patients in oncology and hematology as well as its relation to biosafety measures. The speech of employees revealed that the adoption has been very supportive of these standards, although some have been highlighted gaps in the understanding of employees in relation to biosafety and the proposed categories. CONCLUSION: The analysis of information showed that biosafety has been cited by employees as an immeasurable benefit to safety and occupational health. And the strengths marks in their understanding were: the excellence of care and safety in occupational diseases risk reduction and infections resulting from their work activities, despite some difficulties in adopting appropriate biosafety standards

Segurança do paciente no sistema de medicação: análise de enfermeiros de um hospital de ensino

This study aimed to identify and describe the factors related to Patient Safety in a medication system according to the nurses analysis in a teaching hospital from the photographic analysis method. This was a cross-sectional, descriptive study with mixed approach in a teaching hospital in Rio Grande do Norte. The population consisted of 42 nurses from inpatient units, of which 34 composed the study sample. As eligibility criteria, we defined nurses from public service and nurses who agreed to participate. Ethical determinations were observed, the study was submitted to the Ethics and Research of the University Hospital Onofre Lopes, obtaining the assent with ethical assessment certificate (CAAE 0098.0.051.294-11). For data collection, we used the photographic method (Photographic Analysis Technique) by Patricia Marck (Canada). It was developed in two phases: at first, we randomly captured photos from the medication system, resulting in 282 images; then we selected/processed the photographs, which were reduced to 10 images in Microsoft Excel 2010; in the second phase, the nurses answered the questionnaire divided into socio-professional profile and Digital Photography Scoring Tool (questions a and b ). For analysis of the question a , we used the content analysis technique, and for b , we used the Statistical Package for the Social Sciences 20.0 (temporary license). The socio-professional profile revealed the predominance of females; age group 34-43 years; professionals with specialization; 10-18 years of length of service; and nurses working exclusively in the hospital and who know the Patient Safety. The photographic analysis in relation to Patient Safety resulted in specific categories for each stage of the medication system. Regarding disposal, we identified Proper verification ; Improper verification ; Correct identification ; Disposal in single doses ; and Improper Environment , with predominance of that last category. As for storage: Proper storage ; Improper storage ; Risk of exchange/disappearance ; and Poor hygiene , with special reference to improper storage. In preparation: Risk of exchanging medication/patient ; Inappropriate physical space ; and Inadequate 9 preparation of controlled drugs , highlighting the first category. In drug administration: Lack of Personal Protective Equipment ; Use of Personal Protective Equipment ; Improper administration technique ; Proper administration technique ; Correct drug identification ; Incorrect drug identification ; and Peripheral venous access without identification . From the safety assessment of 10 photographs, by adapting the scores (1-10) to the Likert Scale, we identified three Totally Unsafe (Level 1), three Unsafe (Level 2), three Partially Safe (Level 3), one Safe (Level 4), and no photograph considered Totally Safe. This study identified the prevalence of unsafety in the medication system in the nurses opinion. We were also able to understand that, although nurses identify safety aspects, the most prevalent categories characterize an unsafe assessment. Nursing needs to reflect on its practice, identifying gaps in the medication system in order to achieve a proper and safe care

Influência da retirada de digesta abomasal, para estudos de digestão parcial, sobre a digestibilidade aparente de nutrientes com bovinos

The objective of this trial, using 21 abomasal fistulated bovines, eight months of age and 187 kg of liveweight, was to evaluate the digestibility coefficients of diets containing different protein sources (dry yeast, urea, and cottonseed meal) used in ruminant feeding, the analyses of digestibility coefficients took into account the withdrawal or not of abomasal digesta (phases 2 and I, respectively). There was an increase on the digestibility coefficients of crude protein (52.7 to 55.0%), when abomasal digests was withdrawn. Therefore, it is important that the collection of abomasal digesta in ruminal digestion studies be collected in different periods for studies of total digestion. The ingestion of nutrients/MSU and digestible nutrients/MSU was not affected, independent of abomasal digesta withdrawal.

Identificação das condições gerais de conservação dos reservatórios integrantes do sistema de abastecimento de água de Natal

Infrastructure works are included in strategic areas for the social development. For that matter that all of the investments are very important for the social development. When the population has enough water and an acceptable quality, and it includes a wastewater gathering and its treatment, the whole society became less susceptible to the water diseases. Even the Water Supply and the Sewage depend for its perfect operation of reservoirs, or of the accumulation of water to provide the popular necessity, either due to retention or for the treatment wastewarer. These structures present very specific environmental conditions, because the microclimate created around them, like high environmental humidity and for the existence of many harmful substances for the concrete, such as chloride ions presents in water. The reservoir that compose the System of Water Supply of Natal were built between 1970s and 1980s, a period whom the technical and scientific community did not have in-depth studies about the reinforced concrete mechanism of deterioration. Therefore, these reservoirs have been suffered accelerated deterioration progress, and they have been shown many pathological manifestations strikingly visible. In front of all these problems this academic work aims to identify the generally conditions of conservation of all the reservoirs components of the Water Supply System of Natal. This academic work objectives to develop a recuperation plan for use in these reservoirs, in this academic work it was achieved all the survey of pathological manifestation existing in each reservoir. It was made with local visits, photographic recorders of all manifestations viii and realization of in loco tests. The other step consisted in a application of GDE/UnB metodolgy reformulated by Fonseca (2007). In the step of local visits in each reservoir it was evaluated carbonation depth, by spreading a phenolphthalein solution with 1% of concentration; evaluation of contamination of chlorides, by spreading silver nitrate solution with 1% of concentration, and evaluation of width cracks. After the conclusion of all the testings, it was established that all reservoir, studied in this academic work, have showed an advanced deteriorating condition. It´s presents prevalent pathological manifestations as unacceptable cracks, spots, efflorescence and reinforcement corrosion, and in some cases, chlorides contamination. After the conclusion of the testings and its concatenation it was able to implementing, using GDE/UnB methodology, the order of the restoration its service life and initial safety conditions
