"RELIGIÃO E SAÚDE: UM ESTUDO A RESPEITO DAS REPRESENTAÇÕES DO FIEL CARISMÁTICO SOBRE OS PROCESSOS DE RECUPERAÇÃO DE ENFERMIDADES NOS GRUPOS DE ORAÇÃO DA RCC EM MARINGÁ-PR"

O presente trabalho visa interpretar as representações religiosas do fiel carismático pertencente ao grupo de oração da Renovação Carismática Católica de Maringá, Paraná, quando o mesmo se encontra diante de um processo de enfermidade. Tendo por base a concepção antropológica da saúde e a concepção antropológica interpretativa, o texto abre uma discussão entre essas áreas do conhecimento para interpretar a busca da religião, como sistema de significado e motivação para a recuperação de enfermidades na vida do fiel carismático. O processo saúde/doença, pela visão antropológica, é visto enquanto fenômeno social, preocupando-se com as pessoas, em diferentes culturas e grupos sociais, uma vez que saúde e doença não estão presentes, de forma igual, nas culturas. Compreendendo que a saúde é algo que ultrapassa os conceitos de ser considerada apenas quando um corpo não tem doença, a antropologia propõe um modelo de estudo que inter-relacione cultura/sociedade/natureza, que nos permita refletir, e não reproduzir, o modelo positivista da medicina que fragmenta o corpo, lançando a responsabilidade da doença sobre o enfermo, não considerando sua história, suas crenças, valores e o contexto social em que vive. O estudo revelou, pelas narrativas dos fiéis entrevistados: a busca do grupo de oração da RCC, como lugar de valorização, cuidado humano, e espaço de aproximação com o sagrado; a religião, como algo que lhe confere significado por meio de símbolos religiosos que atuam de forma terapêutica para a recuperação de sua enfermidade; e, por fim, a religião como recurso e sistema de motivação e ânimo no processo de enfrentamento do mal-estar do corpo e da mente, ou seja, a doença propriamente dita.(AU)

COMUNICAÇÃO EM LINHA E RUÍDOS SEMÂNTICOS NA RECUPERAÇÃO DE INFORMAÇÕES EM PESQUISAS CIENTÍFICAS

O pesquisador científico necessita de informações precisas, em tempo hábil para conclusão de seus trabalhos. Com o advento da INTERNET, o processo de comunicação em linha, homem x máquina, mediado pelos mecanismos de busca, tornou-se, simultaneamente, um auxílio e uma dificuldade no processo de recuperação de informações. O pesquisador teve que adaptar-se ao modo de operar da INTERNET e incluiu conhecimentos de diferenças idiomáticas, de terminologia, além de utilizar instrumentos que lhe forneçam parâmetros para obter maior pertinência e relevância nos dados. O uso de agentes inteligentes para melhoria de resultados e a diminuição de ruídos semânticos têm sido apontados como soluções para aumento da precisão no resultado das buscas. O estudo de casos exploratório realizado analisa a pesquisa em linha a partir da teoria da informação e propõe duas formas de otimizar o processo comunicacional com vistas à pertinência e relevância dos dados obtidos: a primeira sugere a aplicação de algoritmos que utilizem o vocabulário controlado como mediador do processo de comunicação utilizando-se dos descritores para recuperação em linha. , e a segunda ressalta a importância dos agentes inteligentes no processo de comunicação homem-máquina.(AU)

COMPARAÇÃO DAS FORÇAS DE DEFLEXÃO LIBERADAS ENTRE OS FIOS ORTODÔNTICOS ESTÉTICOS E SUA RELAÇÃO COM O REVESTIMENTO

O objetivo do presente estudo consistiu em comparar as forças de deflexão in vitro entre fios estéticos e fio NiTi, para verificar a força máxima e da região platô e determinar sua correlação com o diâmetro do fio com e sem revestimento. Foram realizados dez ensaios de sete marcas comerciais de arcos précontornados, sendo seis fios estéticos (Invu (I), Optis (O), Flexy Super Elastic Esthetic (FSEE), Niticosmetic (N), Orthocosmetic Elastinol (OE) e Pro Form Coated Nitanium (PFCN)) e um fio NiTi superelástico (Nitinol Super Elastic (NSE)), aplicando-se o teste de curvatura de três pontos, associado a máquina de ensaios universal EMIC. Desenvolveu-se um dispositivo com braquetes cerâmicos (Transcend), cujos fios foram presos por elásticos modulares, sendo obtidos os valores da força de deflexão em 3,0, 2,0 e 1,0mm. O diâmetro dos fios com e sem revestimento foram mensurados com o especímetro digital Micromaster. A análise de variância a um critério (p<0,05) mostrou diferença significante entre os fios e o teste post-hoc de Tukey determinou que a força de deflexão em 3mm para o Ode deflexão (2-1mm) na região platô e mostrou que os fios O, FSEE e N apresentaram forças constantes. O fio da N apresentou o maior diâmetro entre as amostras, enquanto que os fios NSE e O, os menores. O Coeficiente de Correlação de Pearson mostrou que houve correlação entre o diâmetro do fio e a força de deflexão. Pode se concluir que há diferenças entre as forças produzidas pelos fios estéticos e que a força é diretamente proporcional ao seu diâmetro do fio com e sem revestimento para todas as deflexões, ou seja, quanto maior o diâmetro, maior a força produzida.

A IMPORTÂNCIA DA FAMÍLIA NA RECUPERAÇÃO DE PACIENTES INTERNADOS NA UNIDADE DE TERAPIA INTENSIVA

A Unidade de Terapia Intensiva (UTI) é um setor do hospital destinado ao atendimento de pacientes em estado crítico, que requer cuidados complexos e controles rígidos e, por isso sempre gera um ambiente estressante, não só para a equipe que atende ao paciente mas também aos familiares e portanto induz muitas vezes ao processo de depressão. Estes fatores leva-nos a abordar a necessidade de humanização, no atendimento ao paciente, bem como de seus familiares. A preocupação com a humanização deve estar presente nas equipes de enfermagem como filosofia-diretriz e deve ser um indicador de qualidades desses serviços. Humanizar a UTI significa cuidar do paciente como um todo, englobando o contexto bio-psico-social, incorporando os valores sociais e da família, as esperanças, os culturais e as preocupações pessoais. A humanização deve fazer parte da filosofia da enfermagem. O ambiente físico, os recursos materiais e tecnológicos são importantes, porém não mais significativos do que a natureza humana. O pensamento em ações da equipe de enfermagem, alimentam a reflexão crítica e a construção de uma realidade mais humana e menos agressiva e hostil para as pessoas que diariamente convivem no hospital. A hospitalização altera a rotina não só do paciente mas também dos familiares. De certa forma, a própria hospitalização pode ser vivida como abandono ou morte, à medida que implica um afastamento das pessoas queridas, da casa, como também uma invasão de privacidade. Este trabalho procurou Identificar as necessidades dos familiares ou visitantes, frente à equipe de saúde durante o período de internação na UTI e avaliar o grau de satisfação em relação à qualidade das informações e ao suporte dados à família ou visitante. Os resultados indicam que no Hospital Heliópolis, onde o trabalho foi conduzido, os entrevistados estavam satisfeitos com a equipe multiprofissional pois os pacientes eram bem cuidados, havendo preocupação com os pacientes, e que os médicos, além de compreensivos e competentes, forneceram as informações de modo que eles pudessem compreender,. Porém deve-se ressaltar que 48% dos entrevistados apontam a necessidade de apoio psicológico.(AU)

Avaliação da influência de cinza da casca de arroz em cimentos para poços de petróleo submetidos à injeção de vapor

Reservoirs that present highly viscous oils require methods to aid in their recovery to the surface. The elev ated oil viscosity hinders its flow through porous media and conventional recovery methods have not obtained significant efficiency. As such, the injection of steam into the reservoir through an injection well has been the most widely used method of therma l recovery, for it allows elevated volumes of recovery due to the viscosity reduction of the oil, facilitating the oil’s mobility within the rock formation and consequently into the production well where it will be exploited. On the other hand, the injecti on of vapor not only affects the fluids found in the rock pores, but the entire structure that composes the well where it is injected due to the high temperatures used in the process. This temperature increment is conducted to the cement, found in the annu lus, responsible for the isolation of the well and the well casing. Temperatures above 110 ̊C create new fazes rich in calcium in the cement matrix, resulting in the reduction of its permeability and the consequential phenomenon of mechanical resistance ret rogression. These alterations generate faults in the cement, reducing the well’s hydraulic isolation, creating insecurity in the operations in which the well will be submitted as well as the reduction of its economic life span. As a way of reducing this re trograde effect, this study has the objective of evaluating the incorporation of rice husk ash as a mineral additive substitute of silica flour , commercially utilized as a source of silica to reduce the CaO/SiO 2 ratio in the cement pastes submitted to high temperatures in thermal recovery. Cement pastes were formulated containing 20 and 30% levels of ash, apart from the basic paste (water + cement) and a reference paste (water + cement + 40% silica flour) for comparison purposes. The tests were executed th rough compression resistance tests, X - Ray diffraction (XRD) techniques, thermogravimetry (TG), scanning electron microscopy (SEM) and chemical anal ysis BY X - ray fluorescence (EDS) on the pastes submitted to cure at low temperatures (45 ̊C) for 28 days following a cure at 280 ̊C and a pressure of 2,000 PSI for 3 days, simulating vapor injection. The results obtained show that the paste containing 30% r ice shell ash is satisfactory, obtaining mechanical resistance desired and equivalent to that of the paste containing 40% silica flour, since the products obtained were hydrated with low CaO/SiO 2 ratio, like the Tobermorita and Xonotlita fases, proving its applicability in well subject to vapor injection.

Contribuição ao estudo avançado das argamassas de alto desempenho para reparos estruturais

Inúmeras estruturas de concreto no Brasil e no mundo estão atingindo o limite de sua vida útil projetada, completando um ciclo de cinco ou mais décadas de uso e operação. Além das estruturas mais antigas, existem ainda estruturas com reduzido tempo de serviço, e qualidade discutível, que já apresentam patologias em estado tão avançado que chegam a comprometer o seu desempenho. Vindo ao encontro dessas necessidades e no sentido de contribuir para o avanço científico e tecnológico do setor, este trabalho apresenta um método para dosagem, preparo e aplicação de argamassas de alto desempenho para recuperação de estruturas deterioradas, além de sugerir procedimentos para a realização desses reparos, fomentando a cultura das manutenções preventivas e desmistificando a complexidade atribuída a tais operações. Para tanto, foram realizados ensaios mecânicos, microestruturais e relacionados à durabilidade em corpos-de-prova moldados com sílica ativa e látex de estireno-butadieno. Os resultados indicaram que a adoção desses ingredientes, na composição da argamassa de reparo, provocou uma redução significativa da permeabilidade total e descontinuidade de poros, assim como promoveu uma melhor integridade dos constituintes da argamassa, traduzindo-se em uma ampliação, expressiva, das suas capacidades mecânicas. Quando comparada aos produtos industrializados da construção civil, com padrões similares, proporcionou uma economia da ordem de 85%, que permitiria recuperar, com os mesmos custos, quase cinco vezes mais estruturas comprometidas. Este estudo, de viés altamente tecnológico, vem oferecer à construção civil uma argamassa polimérica de alto desempenho, com função reparadora e custo mais acessível, que pode ser adotada em canteiros de obras, implementando ações de natureza sustentável e ainda atendendo às atuais exigências elencadas pela literatura, relacionadas à desempenho, vida útil e durabilidade das estruturas reparadas.

A argamassa da casa e do conflito: os usos políticos da construção da cidade da esperança feitos pelo grupo aluizista (1964-1966)

Nous nous proposons à analyser les usages politiques que le groupe lié au gouvernement Aluízio Alves a fait d’un complexe d’habitation s’appelé Cidade da Esperança, qui a été construit en Natal dans les années 1960. Ce nouvel espace a été utilisé pour solutionner la crise d’habitation dans la capital, dont le número de personne augmentait fortement. Cette élévation, néanmoins, n’a été pas accompagné pari passu pour l’expansion de l’offre des maisons pour le marché et ce pénurie se transformer dans un problème social e politique. La Cidade da Esperança, alors, a été une réponse de l’État à la population et entre ces dynamiques, le groupe du gouvernement Aluízio Alves a su explorer la question parce qu’il a utilisé l’espace pour négocier avec differents agentes sociaux et il aussi a réussi élire Agnelo Alves, le diretor de la construction, à maire de Natal. Par la construction de cette analyse nous utilisons le journal gouvernamental Tribuna do Norte et le journal catholique A Ordem. Ils ont représenté dans ces pages les problèmes de pénurie des maisons et aussi les appropriations de la Cidade da Esperança. Pour ça nous pouvons reconstruire ces processus historiques. Pour les journaux est possible connaître du quotidien des travaux, les actions des sujets réponsable et les tensions politiques du groupe aluizista avec l’autre lié à Dinarte Mariz. Ainsi, ils possibilites l’étude de l’utilisation de la Cidade da Esperança dans l’intérieur d’une réseau des tensions et l’examen de la recherche pour legitimité dans un champ politique très poralisé.

Recuperação avançada de óleos pesados em poços fraturados utilizando aquecimento eletromagnético indutivo

The success achieved by thermal methods of recovery, in heavy oils, prompted the emergence of studies on the use of electromagnetic waves as heat generating sources in oil reservoirs. Thus, this generation is achieved by three types of different processes according to the frequency range used. They are: the electromagnetic induction heating, the resistive and the dielectric, also known as radiation. This study was based on computer simulations in oil reservoirs with characteristics similar to those found in the sedimentary basins of the Brazilian Northeast. All cases studied were simulated using the software STARS, CMG (Computer Group, version 2012.10 Modeling). Some simulations took into account the inclusion of electrically sensitive particles in certain sectors of the reservoir model studied by fracturing. The purpose of this work is the use of the electromagnetic induction heating as a recovery method of heavy oil, to check the influence of these aforementioned particles on the reservoir model used. Comparative analyses were made involving electromagnetic induction heating, the operation of hydraulic fracturing and the injection of water to the different situations of the reservoir model studied. It was found that fracturing the injection well in order that the electromagnetic heating occurs in the same well where there is water injection, there was a considerable increase in the recovery factor and in the cumulative oil production in relation to the models in which hydraulic fracturing occurred in the production well and water injection in the injection well. This is due to the generation of steam in situ in the reservoir.

Recuperação e purificação do antígeno 503 de Leishmania i. chagasi expresso em E. coli e remoção de endotoxina utilizando adsorção em leito expandido

The growing interest and applications of biotechnology products have increased the development of new processes for recovery and purification of proteins. The expanded bed adsorption (EBA) has emerged as a promising technique for this purpose. It combines into one operation the steps of clarification, concentration and purification of the target molecule. Hence, the method reduces the time and the cost of operation. In this context, this thesis aim was to evaluate the recovery and purification of 503 antigen of Leishmania i. chagasi expressed in E. coli M15 and endotoxin removal by EBA. In the first step of this study, batch experiments were carried out using two experimental designs to define the optimal adsorption and elution conditions of 503 antigen onto Streamline chelating resin. For adsorption assays, using expanded bed, it was used a column of 2.6 cm in diameter by 30.0 cm in height coupled to a peristaltic pump. In the second step of study, the removal of endotoxin during antigen recovery process was evaluated employing the non-ionic surfactant Triton X-114 in the washing step ALE. In the third step, we sought developing a mathematical model able to predict the 503 antigen breakthrough curves in expanded mode. The experimental design results to adsorption showed the pH 8.0 and the NaCl concentration of 2.4 M as the optimum adsorption condition. In the second design, the only significant factor for elution was the concentration of imidazole, which was taken at 600 mM. The adsorption isotherm of the 503 antigen showed a good fit to the Langmuir model (R = 0.98) and values for qmax (maximum adsorption capacity) and Kd (equilibrium constant) estimated were 1.95 mg/g and 0.34 mg/mL, respectively. Purification tests directly from unclarified feedstock showed a recovery of 59.2% of the target protein and a purification factor of 6.0. The addition of the non-ionic surfactant Triton X-114 to the washing step of EBA led to high levels (> 99%) of LPS removal initially present in the samples for all conditions tested. The mathematical model obtained to describe the 503 antigen breakthrough curves in Streamline Chelanting resin in expanded mode showed a good fit for both parameter estimation and validation steps. The validated model was used to optimize the efficiencies, achieving maximum values of the process and of the column efficiencies of 89.2% and 75.9%, respectively. Therefore, EBA is an efficient alternative for the recovery of the target protein and removal of endotoxin from an E. coli unclarified feedstock in just one step.

Estudo da influência de sistemas microemulsionados na molhabilidade de arenitos e na recuperação avançada de petróleo

Sandstone-type reservoir rocks are commonly responsible for oil accumulation. The wettability is an important parameter for the physical properties of the container, since it interferes in characteristics such as relative permeability to the aqueous phase, residual oil distribution in the reservoir, operating characteristics with waterflood and recovery of crude oil. This study applied different types of microemulsion systems - MES - in sandstone reservoirs and evaluated their influences on wettability and residual oil recovery. For this purpose, four microemulsion were prepared by changing the nature of ionic surfactants (ionic and nonionic). Microemulsions could then be characterized by surface tension analysis, density, particle diameter and viscosity in the temperature range 30° C to 70° C. The studied oil was described as light and the sandstone rock was derived from the Botucatu formation. The study of the influence of microemulsion systems on sandstone wettability was performed by contact angle measurements using as parameters the rock treatment time with the MES and the time after the brine surface contact by checking the angle variation behavior. In the study results, the rock was initially wettable to oil and had its wettability changed to mixed wettability after treatment with MES, obtaining preference for water. Regarding rock-MES contact time, it was observed that the rock wettability changed more when the contact time between the surface and the microemulsion systems was longer. It was also noted only a significant reduction for the first 5 minutes of interaction between the treated surface and brine. The synthesized anionic surfactant, commercial cationic, commercial anionic and commercial nonionic microemulsion systems presented the best results, respectively. With regard to enhanced oil recovery performance, all systems showed a significant percentage of recovered oil, with the anionic systems presenting the best results. A percentage of 80% recovery was reached, confirming the wettability study results, which pointed the influence of this property on the interaction of fluids and reservoir rock, and the ability of microemulsion systems to perform enhanced oil recovery in sandstone reservoirs.

Formulação de pasta de cimento flexível utilizando planejamento experimental

Steam injection is an oil recovery method accomplished by introducing steam directly into the oil well to the reservoir. The steam causes dilation of the casing, which, after reduction in temperature, tends to return to the initial dimensions: causing the formation of cracks in the cement and loss of hydraulic isolation.. In this context, the type of the SBR latex is used to improve the flexibility of the cement matrix by reducing the amount of fatigue failure. To prevent these failures, the mechanical resistance parameters should be carefully adjusted to well conditions. This work aims to study the mechanical behavior of cement slurry systems additivated with SBR latex for cementing oil wells subject to steam injection. Through the central composite factorial design was studied the behavior of the compressive strength by varying the density of the paste between 1.75 g /cm³ (14.6 lb/ Gal) and 1.89 g/cm³ (15,8lb / Gal), curing time between 4 days and 28 days and concentration of SBR Latex between 0 L / m³ and 534.722 L / m³ (0 gpc and 4 gpc). The results showed that increasing the concentration of SBR latex, within the given ranges, there was a decreased compression resistance and elastic modulus by increasing the elastic deformability of the slurry. From the results it can determine best slurries formulation conditions in oil well cementing operations subject to steam injection.

Avaliação clínica e da qualidade de vida utilizando dois protocolos para recuperação miofuncional em pacientes que se submeteram à cirurgia ortognática: resultados preliminares

The objective of this randomized, blind and prospective clinical trial was to compare the pain, the edema, the mandibular movements, the masticatory efficiency and life quality, in the first 60 days after surgery using 2 different clinical protocols for myofunctional recovery, in patients who underwent orthognathic surgery. A sample of 19 patients was used and divided into 2 groups. The control group (CG) consisted of 10 patients who had postoperative rehabilitation guided by a standard protocol, conducted by the Service of Surgery and Traumatology Oral and Maxillofacial. In other hand, the experimental group (EC) totaled 9 patients who received the speech therapy rehabilitation protocol specialized, by professionals in the area. The variables pain, edema and mandibular movements were analyzed during 48h, 96h, 7 days, 14 days, 30 and 60 days post-surgery. The masticatory efficiency and the quality of life were classified with 60 days after surgery . The data were submitted an analysis of variance, Student's t-test and Fisher's independence, at the level of 5% probability. It was identified that patients of GE have benefited in the first 14 days(p<0,001), as they have had reported less pain than those in the CG. Significant statistics differences between groups for pain parameters (after 14 days) (p=0,065), edema(p=0,063), mandibular movements(p=0,068), masticatory efficiency(p=0,630) and the impact on quality of life (p=0,813) were not observed on this study. The speech therapy protocol for myofunctional recovery (EG), although it has not obtained statistical results superiors than the CG in the general context, presents itself as a viable alternative to conventional therapy assumed by many maxillofacial surgeons, allowing the surgeon to optimize time with patients in the period postoperatively.
