Saúde Mental e enfermagem: em busca da integralidade na ESF

The present work shows an inquiry about the conceptions and practical work of the nursing professionals on the accompaniment of mental sick patients in the Family s Health Strategy, under the approach of the completeness in health. The justification of this research is given by bringing an special attention concerning the subjet to these professionals of health: the gradual abandonment of the traditional manicomial model leads to the insertion of mental patients in the community . The nursing professionals must be prepared to receive these patients in the basic net of health and contribute to help their adaptation and insertion in the social environment as citizen. In this context, considering the entire attention to the mental health, it is important to detach that the assistance to the patient must search his reinsertion in the community by providing programs that develops his sociability. This analytical study was developed using a qualitative approach and a thematic verbal history. Ten nurses of Nova Natal s Health of the Family Unit, of Felipe Camarão Mista s Unit and of Cidade da Esperança s Health Unit contributed for its development . The information was acquired through an instrument research that made possible the accomplishment of the interviews. These ones were set previously and counted on the assent of the participants. The interviews were recorded and analyzed in accordance with the pertinent literature concerning the subject. The aggregation of the information was then discussed. At this moment three thematic axles were defined dividing the categories of analysis. According to the results of the interviews, the practical procedure given to the patients with mental upheaval is resumed by the prescription of psicotroprics medicaments. It doesn t provide an accompaniment by the professionals of health, specifically, nurses, to the patients and their families. The lack of qualification and a multi-professional team emerged as one of the challenges for the implementation of practical procedures towards the patients with mental upheaval. Therefore, the results of this research show the necessity of transformations in the current scene of the mental health in the Family s Health Strategy. These changes can be reached by politics investments on the mental health area, not only financially but by providing human resources that should allow the professionals to exert the completeness procedures

Modelagem e simulação da solubilização da parafina em tubos circulares e em regime laminar

O óleo produzido nos novos campos de petróleo está cada vez mais parafínico e viscoso, com isso, à medida que o óleo é escoado, parafinas são depositadas sobre as paredes internas do tubo, e ao longo do tempo, tendem a reduzir drasticamente a área transversal ao escoamento. Visando estudar o processo de solubilização da parafina em dutos, esse trabalho objetiva desenvolver modelos matemáticos que represente o processo, com base nos fenômenos envolvidos no mesmo tais como transferência de massa, transferência de energia e equilíbrio sólido-líquido, implementando-os em um ambiente de desenvolvimento VBA (Visual Basic) for Excel ®. O presente trabalho foi realizado em quatro etapas: i) modelagem dos fenômenos de transferência de calor e massa, ii) modelagem da rotina dos coeficientes de atividade através do modelo UNIFAC e modelagem do sistema de equilíbrio sólido-líquido; iii) modelagem matemática do processo de solubilização e cálculo da espessura da parafina ao longo do tempo; iv) implementação dos modelos em um ambiente de desenvolvimento VBA for Excel® e criação de um simulador com uma interface gráfica, para simular o processo de solubilização da parafina depositada em dutos e sua otimização. O simulador conseguiu produzir soluções bastante adequadas, mantendo continuidade das equações diferenciáveis do balanço de energia e de massa, com uma interpretação física viável, sem a presença de dissipação de oscilações nos perfis de temperatura e massa. Além disso, esse simulador visa permitir a simulação nas diversas condições de escoamento, bem como compreender a importância das variáveis (vazão, temperatura de entrada, temperatura externa, cadeia carbônica do solvente). Através dos resultados foram possíveis verificar os perfis de temperatura, fração molar e o de solubilização

Os Centros de Especialidades Odontológicas como suporte da atenção básica: uma avaliação na perspectiva da integralidade

The public dental services in Brazil were limited, practically, to the basic care, so that the specialized services acted, up to 2002, no more than 3,5% of the total of clinical procedures. That lower offer reveals the difficulty of continuity of the attention, that is, the comprehensiveness in the assistance, particulary, the reference and counter-reference system. Brasil Sorridente search to supply those needs when proposing Speciality Dental's Centers(CEOs Centros de Especialidades Odontológicas, Brazil) to compose the services of average complexity. In 2005, Ministry of Health enabled the three CEOs of Natal, located in the North II, East and West Sanitary Districts. This investigation evaluated the implantation of these CEOs, as support of the family health care teams, in the perspective of organization of the services in assistencial nets in Natal/RN. It was a study of evaluation, with qualitative approach and some quantitative data as contribution. Dentists, users and managers were interviewed to identify and to understand their perceptions, relationships and experiences in the daily of the services. The conceptual base that orientated the investigation was the principle of comprehensiveness, in its operational sense of the hierarchization in health attention levels. The collection of data was done with documental research, direct observation and semi-structured interview. The analysis was accomplished by triangulation of the extracted content from the used techniques and sources of interviewed groups depositions, looking for theoretical-conceptual support in specific bibliography. The results pointed aspects that go away from the comprehensiveness like: low resolution of problems in the basic net; little valorization of the space in the health units; traditional models of access to health services, insufficient offer for some specialties, compromising the reference and counter-reference system; practices centered in procedures in the CEO; bureaucratic directions from basic care to the specialized service; disintegrated and disjointed system among levels of attention; disrespect to the municipal protocol. On the other hand, there is an approach of compreensiveness in situations like: increase of the access and covering in the Family Health Strategy (ESF Estratégia Saúde da Família, Brazil); larger approach between professional and user; tendency to the quantitative and qualitative growth of specialized actions; punctual initiatives of relationships among levels; existence of protocol to guide professionals

Simulação da destilação molecular de filme descendente para o petróleo

The heavy part of the oil can be used for numerous purposes, e.g. to obtain lubricating oils. In this context, many researchers have been studying alternatives such separation of crude oil components, among which may be mentioned molecular distillation. Molecular distillation is a forced evaporation technique different from other conventional processes in the literature. This process can be classified as a special distillation case under high vacuum with pressures that reach extremely low ranges of the order of 0.1 Pascal. The evaporation and condensation surfaces must have a distance from each other of the magnitude order of mean free path of the evaporated molecules, that is, molecules evaporated easily reach the condenser, because they find a route without obstacles, what is desirable. Thus, the main contribution of this work is the simulation of the falling-film molecular distillation for crude oil mixtures. The crude oil was characterized using UniSim® Design and R430 Aspen HYSYS® V8.5. The results of this characterization were performed in spreadsheets of Microsoft® Excel®, calculations of the physicochemical properties of the waste of an oil sample, i.e., thermodynamic and transport. Based on this estimated properties and boundary conditions suggested by the literature, equations of temperature and concentration profiles were resolved through the implicit finite difference method using the programming language Visual Basic® (VBA) for Excel®. The result of the temperature profile showed consistent with the reproduced by literature, having in their initial values a slight distortion as a result of the nature of the studied oil is lighter than the literature, since the results of the concentration profiles were effective allowing realize that the concentration of the more volatile decreases and of the less volatile increases due to the length of the evaporator. According to the transport phenomena present in the process, the velocity profile tends to increase to a peak and then decreases, and the film thickness decreases, both as a function of the evaporator length. It is concluded that the simulation code in Visual Basic® language (VBA) is a final product of the work that allows application to molecular distillation of petroleum and other similar mixtures.

Modelagem da degradação de fenol em efluentes aquosos através do processo de foto-fenton

Advanced Oxidation Processes (AOP) are techniques involving the formation of hydroxyl radical (HO•) with high organic matter oxidation rate. These processes application in industry have been increasing due to their capacity of degrading recalcitrant substances that cannot be completely removed by traditional processes of effluent treatment. In the present work, phenol degrading by photo-Fenton process based on addition of H2O2, Fe2+ and luminous radiation was studied. An experimental design was developed to analyze the effect of phenol, H2O2 and Fe2+ concentration on the fraction of total organic carbon (TOC) degraded. The experiments were performed in a batch photochemical parabolic reactor with 1.5 L of capacity. Samples of the reactional medium were collected at different reaction times and analyzed in a TOC measurement instrument from Shimadzu (TOC-VWP). The results showed a negative effect of phenol concentration and a positive effect of the two other variables in the TOC degraded fraction. A statistical analysis of the experimental design showed that the hydrogen peroxide concentration was the most influent variable in the TOC degraded fraction at 45 minutes and generated a model with R² = 0.82, which predicted the experimental data with low precision. The Visual Basic for Application (VBA) tool was used to generate a neural networks model and a photochemical database. The aforementioned model presented R² = 0.96 and precisely predicted the response data used for testing. The results found indicate the possible application of the developed tool for industry, mainly for its simplicity, low cost and easy access to the program.
