Efeito da Gália como aditivo de sinterização em eletrólitos cerâmicos à base de céria sintetizados pelo método de complexação de cátions

Fuel cells are considered one of the most promising ways of converting electrical energy due to its high yield and by using hydrogen (as fuel) which is considered one of the most important source of clean energy for the future. Rare earths doped ceria has been widely investigated as an alternative material for the electrolyte of solid oxide fuel cells (SOFCs) due to its high ionic conductivity at low operating temperatures compared with the traditional electrolytes based on stabilized zirconia. This work investigates the effect of gallium oxide (Gallia) as a sintering aid in Eu doped ceria ceramic electrolytes since this effect has already been investigated for Gd, Sm and Y doped ceria electrolytes. The desired goal with the use of a sintering aid is to reduce the sintering temperature aiming to produce dense ceramics. In this study we investigated the effects on densification, microstructure and ionic conduction caused by different molar fraction of the dopants europium (10, 15 and 20%) and gallium oxide (0.3, 0.6 and 0.9%) in samples sintered at 1300, 1350 and 1450 0 C. Samaria (10 and 20%) doped ceria samples sintered between 1350 and 1450 °C were used as reference. Samples were synthesized using the cation complexation method. The ceramics powders were characterized by XRF, XRD and SEM, while the sintered samples were investigated by its relative density, SEM and impedance spectroscopy. It was showed that gallia contents up to 0.6% act as excellent sintering aids in Eu doped ceria. Above this aid content, gallia addition does not promote significant increase in density of the ceramics. In Ga free samples the larger densification were accomplished with Eu 15% molar, effect expressed in the microstructure with higher grain growth although reduced and surrounded by many open pores. Relative densities greater than 95 % were obtained by sintering between 1300 and 1350 °C against the usual range 1500 - 1600 0 C. Samples containing 10% of Sm and 0.9% of Ga reached 96% of theoretical density by sintering at 1350 0 C for 3h, a gain compared to 97% achieved with 20% of Sm and 1% of Ga co-doped cerias sintered at 1450 0 C for 24 h as described in the literature. It is found that the addition of gallia in the Eu doped ceria has a positive effect on the grain conductivity and a negative one in the grain boundary conductivity resulting in a small decrease in the total conductivity which will not compromise its application as sintering aids in ceria based electrolytes. Typical total conductivity values at 600 and 700 °C, around 10 and 30 mS.cm -1 respectively were reached in this study. Samples with 15% of Eu and 0.9 % of Ga sintered at 1300 and 1350 °C showed relative densities greater than 96% and total conductivity (measured at 700 °C) between 20 and 33 mS.cm -1 . The simultaneous sintering of the electrolyte with the anode is one of the goals of research in materials for SOFCs. The results obtained in this study suggest that dense Eu and Ga co-doped ceria electrolytes with good ionic conductivity can be sintered simultaneously with the anode at temperatures below 1350 °C, the usual temperature for firing porous anode materials

Análise das emissões gasosas de um veículo flex funcionando com diferentes combustíveis

Efforts in research and development of new technologies to reduce emission levels of pollutant gases in the atmosphere has intensified in the last decades. In this context, it can be highlighted the modern systems of electronic engine management, new automotive catalysts and the use of renewable fuels which contributes to reduce the environmental impact. The purpose of this study was a comparative analysis of gas emissions from a automotive vehicle, operating with different fuels: natural gas, AEHC or gasoline. To execute the experimental tests, a flex vehicle was installed on a chassis dynamometer equipped with a gas analyzer and other complementary accessories according to the standard guidelines of emission and security procedures. Tests were performed according to NBR 6601 and NBR 7024, which define the urban and road driving cycle, respectively. Besides the analysis of exhaust gases in the discharge tube, before and after the catalyst, using the suction probe of the gas analyzer to simulate the vehicle in urban and road traffic, were performed tests of fuel characterization. Final results were conclusive in indicating leaded gasoline as the fuel which most contributed with pollutant emissions in atmosphere and the usual gasoline being the fuel which less contributed with pollutant emissions in atmosphere

Efeito da perda de carga e calor no poço injetor no processo de drenagem gravitacional assistido com vapor e solvente

Nowadays, most of the hydrocarbon reserves in the world are in the form of heavy oil, ultra - heavy or bitumen. For the extraction and production of this resource is required to implement new technologies. One of the promising processes for the recovery of this oil is the Expanding Solvent Steam Assisted Gravity Drainage (ES-SAGD) which uses two parallel horizontal wells, where the injection well is situated vertically above the production well. The completion of the process occurs upon injection of a hydrocarbon additive at low concentration in conjunction with steam. The steam adds heat to reduce the viscosity of the oil and solvent aids in reducing the interfacial tension between oil/ solvent. The main force acting in this process is the gravitational and the heat transfer takes place by conduction, convection and latent heat of steam. In this study was used the discretized wellbore model, where the well is discretized in the same way that the reservoir and each section of the well treated as a block of grid, with interblock connection with the reservoir. This study aims to analyze the influence of the pressure drop and heat along the injection well in the ES-SAGD process. The model used for the study is a homogeneous reservoir, semi synthetic with characteristics of the Brazilian Northeast and numerical simulations were performed using the STARS thermal simulator from CMG (Computer Modelling Group). The operational parameters analyzed were: percentage of solvent injected, the flow of steam injection, vertical distance between the wells and steam quality. All of them were significant in oil recovery factor positively influencing this. The results showed that, for all cases analyzed, the model considers the pressure drop has cumulative production of oil below its respective model that disregards such loss. This difference is more pronounced the lower the value of the flow of steam injection

Uma metodologia para a análise do desempenho sustentável dos postos de revenda de combustível na cidade de Natal/RN, com o uso de data envelopment analysis-DEA

The increasing use of fossil fuels in line with cities demographic explosion carries out to huge environmental impact in society. For mitigate these social impacts, regulatory requirements have positively influenced the environmental consciousness of society, as well as, the strategic behavior of businesses. Along with this environmental awareness, the regulatory organs have conquered and formulated new laws to control potentially polluting activities, mostly in the gas stations sector. Seeking for increasing market competitiveness, this sector needs to quickly respond to internal and external pressures, adapting to the new standards required in a strategic way to get the Green Badge . Gas stations have incorporated new strategies to attract and retain new customers whom present increasingly social demand. In the social dimension, these projects help the local economy by generating jobs and income distribution. In this survey, the present research aims to align the social, economic and environmental dimensions to set the sustainable performance indicators at Gas Stations sector in the city of Natal/RN. The Sustainable Balanced Scorecard (SBSC) framework was create with a set of indicators for mapping the production process of gas stations. This mapping aimed at identifying operational inefficiencies through multidimensional indicators. To carry out this research, was developed a system for evaluating the sustainability performance with application of Data Envelopment Analysis (DEA) through a quantitative method approach to detect system s efficiency level. In order to understand the systemic complexity, sub organizational processes were analyzed by the technique Network Data Envelopment Analysis (NDEA) figuring their micro activities to identify and diagnose the real causes of overall inefficiency. The sample size comprised 33 Gas stations and the conceptual model included 15 indicators distributed in the three dimensions of sustainability: social, environmental and economic. These three dimensions were measured by means of classical models DEA-CCR input oriented. To unify performance score of individual dimensions, was designed a unique grouping index based upon two means: arithmetic and weighted. After this, another analysis was performed to measure the four perspectives of SBSC: learning and growth, internal processes, customers, and financial, unifying, by averaging the performance scores. NDEA results showed that no company was assessed with excellence in sustainability performance. Some NDEA higher efficiency Gas Stations proved to be inefficient under certain perspectives of SBSC. In the sequence, a comparative sustainable performance and assessment analyzes among the gas station was done, enabling entrepreneurs evaluate their performance in the market competitors. Diagnoses were also obtained to support the decision making of entrepreneurs in improving the management of organizational resources and promote guidelines the regulators. Finally, the average index of sustainable performance was 69.42%, representing the efforts of the environmental suitability of the Gas station. This results point out a significant awareness of this segment, but it still needs further action to enhance sustainability in the long term

Redução da morbi-mortalidade na síndrome de hellp completa com o uso de altas doses de dexametasona

Objective: To determine the clinical maternal and neonatal outcomes in HELLP syndrome patients treated with dexamethasone who either developed renal injury or renal insufficiency and to identify predictive values of urea and creatinine for the identification of subjects with HELLP syndrome at risk of developing renal insufficiency. Methods: Non-radomized intervention study of dexamethasone use in HELLP syndrome. A total of 62 patients were enrolled at Maternidade Escola Januário Cicco (MEJC). Patients received a total of 30 mg of dexamethasone IV, in three doses of 10 mg every 12 hours. A clinical and laboratory follow up were performed at 24, 48 and 72 hours. Patients were followed up to 6 months after delivery. Patients were grouped in accordance to renal function, i.e, normal and some type of renal lesion. Renal lesion was considered when creatinine was equal or greater than 1.3 mg/dl and diuresis less than 100 ml in 4 hours period and renal insufficiency was defined when dialysis was needed. Results: A total of 1230 patients with preeclampsia were admitted at MEJC. Of those 62 (5%) developed HELLP syndrome. There was no statistical difference in the groups with renal involvement or normal renal function with respect to the demographics, type of anesthesia used and delivery, and weight of the newborn. An improvement in the AST, ALT, LDH, haptoglobine, antithrombine, fibrinogenen and platelets was observed within 72 hours after dexamethosone use. There was a significant increase in the diuresis within the interval of 6 hours before the delivery and 24 hours after it. Of the 62 patients, 46 (74. 2%) had normal renal function and 16 (25.8%) evolved with renal lesion, with 5 (8.1%) needing dialysis. These 5 patients who received dialysis recovered the xi renal function. The delay in administering dexamethasone increased in 4.6% the risk of development of renal insufficiency. Patients with renal insufficiency had received significantly more blood products than subjects without renal lesion (p=0.03). Diuresis, leukocytes, uric acid, urea, creatinine were significantly different between the groups with normal renal function, renal lesion and renal insufficiency. The levels of creatinine 1.2mg/dl and uric acid 51mg/dl, at admission are predictive of subjects who will evolve with renal lesion (p<0.001). Maternal mortality was 3.2%. None of the subjects with renal insufficiency evolved with chronic renal disease. Conclusions: Dexamethasone in patients with HELLP syndrome seems to reduce significantly the hepatic microthrombosis and normalize hemostasis as seen by improvement of liver function. Renal injury can be considered, in HELLP syndrome, when creatinine levels are greater than 1.3 mg/dl and diuresis less than 100 ml/h in interval of 4 hours. The level of creatinine greater than 1.2 mg/dl and urea greater than 51mg/dl are predictive of subjects with HELLP syndrome who will develop renal injury. Patients who receive more red cell packs develop renal insufficiency. Finally, the delay in administering dexamethasone increases the risk of developing renal insufficiency

Hospital humano: etnografia da humanização hospitalar na perspectiva de usuários

This ethnographic work studies the experiences of patients admitted in public (PUH) and private (PRH) hospitals in the Brazilian northeastern region. 28 adult patients of different clinics participated in the study. Data were analyzed by the patient path method, consisting in a combination of complemented and articulated techniques free observation, participating observation, ethnographic interview and patient testimonials collected prospectively during the patients admissions, from their arrival and until their discharge. The analysis was carried out according to the Thematic Categories Analysis Technique and the data were interpreted pursuant to medical anthropology, healthcare humanization and healthcare promotion theoretical references. The ethical principles of Resolution 196/96 were followed. The human hospital, as revealed by the patient, highlights the significance of subjectivity. 225 (54.7%) out of 411 mentioned concepts were collected in a public hospital (PUH) and 186 (45.3%) in a private institution (PRH). The results show that the patient at the PUH and PRH ethnoevaluates different aspects of the healthcare professionals´ human and technical competence, the hospital´s functioning structure, the access to and the ethics in the financial management, and develops overcoming strategies for his stay at the hospital. This ethnoevaluation is mediated by different factors, namely: social and economic status, personality, religiosity, ironic speech, somber diagnosis and satisfied needs, prior hospital experiences and the conditions under which the interview was carried out. A pedagogic proposal for the hospital humanization must include structural, managerial and organizational changes of the offered services and use active methodologies aimed to the political resolution of problematic situations at work and the inclusion of affective and subjective factors, and become as well a tool for the collective learning. This study shows the importance for the user´s ethnoevaluation to be incorporated into the hospital management and care as a guideline in the decision making and clinical action, thus promoting practices that shall lead to a decent and humanized care. The multidisciplinary nature of this study allowed a wide understanding of the user´s perspective as a socially critical ethnoevaluator

Biodistribuição do fitato de sódio marcado com tecnécio-99m em ratos esplenectomizados

O baço, como maior órgão linfóide do corpo humano, desempenha funções imunológicas relevantes, tais como depuração de bactérias da corrente sangüínea, produção de anticorpos e interação com a função hepática. A esplenectomia tem sido evitada sempre que possível, mas quando realizada pode provocar uma série de efeitos indesejáveis. O radiofármaco 99mTc-fitato é usado no diagnóstico de doenças, especialmente no fígado, através de exames de imagem, na dependência de sua biodistribuição. Algumas drogas e intervenções cirúrgicas podem interferir na biodistribuição de radiofármacos e inexistem na literatura dados sobre efeitos da esplenectomia no metabolismo do 99mTc-fitato. O objetivo do trabalho foi avaliar se a esplenectomia interfere na biodistribuição hepática do 99mTc-fitato e na função do fígado em ratos Wistar. Sob anestesia e técnica asséptica, os animais do grupo SP (n=6) foram esplenectomizados. No grupo C (controle; n=6) os animais não foram operados. Após 15 dias de observação, foi injetado de 0,1ml de 99mTc-fitato via plexo orbital (0,66MBq) em todos os animais. Após 30 minutos, foram retiradas amostras hepáticas para determinação do percentual de radioatividade/grama (% ATI/g), usando-se contador gama Wizard Perkin-Elmer. Realizou-se dosagem sérica de ALT, AST e LDH, e leucometria. Estatística pelo teste t, com significância de p>0,05. Observou-se diferença significativa (p=0,034) comparando-se o %ATI/g no fígado dos ratos esplenectomizados (0,990,2) com os controles (0,400,2). ALT, AST e LDH tiveram dosagens significativamente menores e houve leucocitose nos esplenectomizados (p=0,01), comparando-se com os controles. Concluiu-se que, em ratos, a esplenectomia provavelmente provocou alteração na captação de 99mTc-fitato pelo fígado, coincidindo com alterações na função hepática. A realização deste estudo teve caráter multidisciplinar, envolvendo pesquisadores de diversas áreas como Medicina Nuclear, Cirurgia, Análises Clínicas e Estatística. Este aspecto preencheu os requisitos da multidisciplinaridade do Programa de Pós-graduação em Ciências da Saúde

Avaliação da eficácia analgésica no pós-operatório de revascularização do miocárdio: ensaio clínico randomizado controlado

A analgesia pós-operatória eficaz é especialmente importante após cirurgias torácicas, pois, além de aliviar a dor, facilita a retomada de atividades normais, incluindo a deambulação, a respiração e a tosse. Dessa forma, os objetivos deste estudo são: avaliar a eficácia analgésica da associação entre anestesia geral e raquianestesia com morfina e ropivacaína mais esquema multimodal em relação à anestesia geral e esquema multimodal em cirurgia de revascularização do miocárdio; analisar a eficácia analgésica da injeção subcutânea de lidocaína e analgesia multimodal na remoção de tubos torácicos em cirurgia de revascularização do miocárdio. A metodologia consiste em ensaio clínico randomizado, controlado, envolvendo 58 pacientes, de ambos os sexos, com idade média de 59,8  8,9 anos, estado físico ASA II e III. Os participantes foram alocados em dois grupos, sendo o GI composto por indivíduos submetidos à anestesia geral combinada à raquianestesia com morfina 400μg e 6 ml (30mg) a 8 ml (40mg) de ropivacaína a 0,5% e analgesia multimodal; já o GII foi composto por indivíduos submetidos à anestesia geral associada à analgesia multimodal. Foi avaliada a dor, ao despertar, nas primeiras 24 horas, e ao realizar exercício respiratório, ao retirar drenos de torácicos e o tempo para extubação. A análise estatística foi realizada pelos testes do Qui-quadrado e Teste t de Student e o teste de Fisher. O resultado obtido foi o seguinte: o GI apresentou menor intensidade de dor ao despertar (p= 0,001), nas primeiras 24 horas (p= 0,001) e durante a realização dos exercícios respiratórios (p= 0,004). Houve maior necessidade de analgesia complementar no grupo GII, com maior consumo de morfina (p= 0,05), e os efeitos colaterais leves, como náuseas (p= 0,001), vômito (p= 0,002), prurido (p= 0,030), predominaram no GI. Não houve diferença estatisticamente significante entre os grupos (P= 0,47), em relação à intensidade de dor na remoção dos drenos. Após as observações feitas, o estudo sugere que a anestesia geral combinada à raquianestesia com morfina associada à ropivacaína oferece melhor efeito analgésico no pós-operatório de cirurgia cardíaca. Adicionalmente, o estudo sugere que o efeito analgésico da injeção subcutânea de lidocaína 1% associado à analgesia multimodal não é eficaz

Crescimento, desenvolvimento gonadal e composição muscular de matrinxãs (Brycon cephalus) submetidos à restrição alimentar e realimentação durante um ano

Neste trabalho, avaliou-se o efeito da restrição de ração alternada com realimentação no crescimento, desenvolvimento gonadal e composição muscular de matrinxãs (Brycon cephalus) adultos, de ambos os sexos, durante um ano (janeiro de 1998 a janeiro de 1999). Foram utilizados 135 peixes, separados em dois grupos: controle, alimentado diariamente até aparente saciação, e experimental, submetido ininterruptamente a ciclos de três dias de alimentação/2 dias de restrição de ração (40% de restrição ao mês). Foram realizadas 7 amostragens, nas quais foram utilizados 8 a 10 peixes por grupo. Após anestesia, os peixes foram pesados e as gônadas foram retiradas para determinação do IGS, sexo e fase do ciclo reprodutivo. Porções dos músculos branco e vermelho foram retiradas para determinação da porcentagem de lipídio total, proteína bruta, matéria seca e umidade. Os resultados mostraram que a estratégia alimentar utilizada não afetou o crescimento, o desenvolvimento gonadal e a composição muscular do matrinxã. A restrição de ração seguida por realimentação parece ter desencadeado mecanismos de ajuste metabólico para melhor utilização do alimento e aporte suficiente de energia para o crescimento, processo de maturação gonadal e composição corporal. É possível estabelecer formas de manejo alimentar mais econômicas para o matrinxã sem que processos fisiológicos importantes sejam afetados.

Benzocaine and eugenol as anesthetics for Brycon hilarii

A utilização de produtos anestésicos durante práticas de manejo é frequentemente empregada, porém doses corretas de diferentes fármacos e para espécies distintas ainda estão em fases de pesquisa. O objetivo do estudo foi determinar a melhor concentração de benzocaína e eugenol para juvenis de piraputanga (B. hilarii). Foram utilizados 104 juvenis de piraputanga com peso médio de 50,04 ± 20,80 g e comprimento total médio de 16,30 ± 12,32 cm adquiridos em uma piscicultura comercial localizada na região Oeste do Estado do Paraná. O trabalho foi conduzido no Laboratório de Aquicultura do Grupo de Estudos de Manejo na Aquicultura - GEMAq da Universidade Estadual do Oeste do Paraná (UNIOESTE). Os animais foram submetidos a cinco concentrações de benzocaína (50,0; 100,0; 150,0; 200,0 e 250,0 mg L-1) e sete concentrações de eugenol (50,0; 100,0; 150,0; 200,0; 250,0; 300,0 e 350 mg L-1), para a aferição dos tempos referentes à letargia. Para a recuperação, os animais foram mantidos em aquários livre do anestésico e observado o tempo em que retornaram às atividades normais. A melhor dose de benzocaína verificada foi de 100 mg L-1, enquanto a melhor dose de eugenol foi entre 100 e 150 mg L-1.

Biodistribuição do pertecnetato de sódio (Na99mTcO4) em ratos submetidos à ressecção extensa de intestino delgado

Massive resection of the small intestine results in short bowel syndrome with anti-absorptive effect and repercussions on the metabolism. Morphologic and functional evaluation may be necessary in order to control wrapped organs. Scintigraphy an examination with little invading and no biologic damage can be used. The purpose were to assess the biodistribution of sodium pertecnetate in organs of rats subjected to massive resection of the small intestine, the intestinal adaptation of the remnant intestinal mucosa and weight curve evaluation in the postoperative period. Twenty-one Wistar rats were randomly allocated into three groups (n = 7). The operated group named short bowel (SB) after anesthetized was subjected to massive resection of the small intestine; the control group (C), and sham group (SHAM). On the 30th postoperative day, 0.l mL of sodium pertechnetate was injected into the venous orbital plexus. After 30 minutes, the rats were killed with an overdose of anesthetic, and fragments of the liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, femur and brain were harvested. The percentage of radioactivity per gram of tissue (%ATI/g) was determined using Gama Counter WizardTM 1470, PerkinElmer to all samples. Biopsies of 3 cm remaining jejunum were removed to histological analyses. Analysis of variance (ANOVA) and the Tukey test for multiple comparisons were used, considering p<0.05 as significant. The study had the participation of some departments and laboratories, as Nucleus of Experimental Surgery, Department of Surgery, Laboratory of Radiobiology, Department of Pathology and Service of Nuclear Medicine, certifying the character of a multidisciplinary research. The results were no significant differences in %ATI/g of the sodium pertechnetate in the organs of the groups studied (p>0.05). An increase in the weight of the SB rats was observed after the second postoperative week. The jejunal mucosal thickness of the SB rats was significantly greater than that of C and sham rats (p<0.05. The biodistribution of sodium pertechnetate was not affected by massive intestinal resection in rats. An adaptive response by the intestinal mucosa probably contributed to the reversion of weight loss and the biodistribution of sodium pertechnetate was not affected by the surgery

Vertical growth of mini watermelon according to the training height and plant density

A melancia é uma espécie tradicionalmente conduzida em campo no sistema rasteiro. As cultivares de frutos pequenos (1 a 3 kg), que adquirem melhores preços de mercado, vêm sendo cultivadas também em ambiente protegido, onde são conduzidas no sistema vertical, com poda de ramos e raleio de frutos. Essas práticas possibilitam aumentar o adensamento das plantas, a qualidade e a produtividade de frutos em comparação ao sistema rasteiro. Objetivou-se com este trabalho avaliar a influência de três alturas de condução (1,7; 2,2 e 2,7 m) e duas densidades de plantas (3,17 e 4,76 plantas m-2) sobre as características produtivas e qualitativas da mini melancia Smile cultivada em ambiente protegido. A poda da haste principal foi realizada aos 43, 55 e 66 dias após o transplante (DAT) para as alturas de condução de 1,7; 2,2 e 2,7 m, respectivamente. A massa seca dos ramos, dos pecíolos, das folhas e total foram afetados pela altura de condução, cujos maiores valores foram obtidos para as plantas conduzidas a 2,2 e 2,7 m de altura. A área foliar, a área foliar específica e o índice de área foliar não foram influenciados pela altura de condução das plantas. A altura de condução de 2,7 m elevou a produtividade total. Entretanto, a produtividade comercial, a massa média dos frutos e todas as características qualitativas não foram significativamente diferentes das obtidos pela altura de poda de 2,2 m. em relação à densidade de plantas, a melhor opção foi a de 4,76 plantas m-2, pois elevou a produtividade comercial em 37,4% sem reduzir a massa média dos frutos.

Avaliação de efetividade do centro de reabilitação de adultos - CRA/NATAL/RN

Public services with an emphasis on rehabilitation treatment of disabled people, as established law, have aimed to ensure quality and equity assistance in a rehabilitation way to the segment highlighted. As for people with physical disabilities, the Unified Health System (hereby SUS) through the directive GM/ MS No. 818 of 2001, requires the creation of hierarchical and regionalized services networks at different levels of complexity to ensure appropriate assistance. This study whose title is Evaluation of effectiveness of the Adult Rehabilitation Center in Rn: elements for a discussion aimed to evaluate the effectiveness of rehabilitation services that institution, reference in the State of Rio Grande do Norte, has directed its patients, more specifically those who have had a stroke and therefore are disabled ones. From the standpoint of methodological conduction, it was prioritized a qualitative and empirical theoretical research which was carried out from the following courses: literature references with authors who are the themes pertaining to rehabilitation, inclusion, public policy evaluation, health policy and disability; documentary research through Regulation of Technical Procedures, files, records, informative booklets that were of great importance to the knowledge of the institution, as well as its functioning and dynamics of field research that was materialized with the managers, rehabilitation staff and Center s users, through the application of semi-structured interviews as a tool for data collection. The information obtained was analyzed from the critical analysis of discourse. As a result, it was identified some technical, administrative and financial difficulties which have obliterated the effectiveness of services provided, such as: lack of many professionals to meet existing demand, poor quality of equipment and the physical structure, limits on autonomy management as a result of dependence along with the SESAP/RN; besides the excessive bureaucratization in the administrative processes compromising Center s problem-solving needs. However, in the narratives of managers, rehabilitation staff of patients, despite the difficulties, treatment made by Centre has effectiveness to the extent that has been contributing even in a limited way to improve their quality of life
