A pessoa idosa com doença crônica não transmissível atendida em serviços de média complexidade na cidade de Natal/RN

The demographic and epidemiological transition process caused by a declining in birth rates and in mortality, also changes occurred in morbidity and mortality is represented by the increasing of the aging population and the raising of chronic diseases. These diseases are characterized by multiple etiologies, risk factors, long latency period, a prolonged evolution, non-infectious origin and it has association with functional impairment and disability. Thus, elderly with chronic non-communicable disease has priority because they belong to a vulnerable group to get affection of comorbidities in aging, with increased demand and spending on health services. This study is aimed to analyse the understanding of elderly people with chronic non comunicable disease in the medium complexity service as a contribution to the improvement of health care in the city of Natal / RN. This is a descriptive and exploratory study with a quantitative approach, carried out at the Specialized Center for Elderly Health Care and at the Pescadores Hospital. The population was composed of 4,180 persons with a sample of 124 elderly aged above 60 years, attended in these medium complexity services. The instrument, a structured form, adapted from a questionnaire for monitoring risk and protective factors for chronic disease of the Ministry of Health. To collect data was was used the interview form containing demographic data, habits, health status and health care services. The results were processed using the Statistical Package for Social Science, version 18.0, analyzed by simple statistics. It was found that most seniors were female, predominantly between 70 and 74 years old, married, with a brown skin tone and Catholic religion, more than half had incomplete basic education, family income between one to two minimum wages and living with their families. Regarding the interviewers lifestyle, 94.4%, of them ate chicken and 97.6%, fruits, it was observed a reduction in smoking, alcoholism habits and physical activity according to the increasing age, 58.1 and 18.5% had insomnia18,5 % used sleeping pills. The elderly (51.6%) reported using services in times of sickness, seeking primary care at first (30.6%), 52% did not receive referral and was looking for free demand (38.7%). The most reported morbidity was hypertension, followed by musculoskeletal disorders. Regarding the difficulties in seeking health services, the delay in treatment and the waiting line were the most cited by the elderly. Almost all of them reported no activities to promote health in these services and those who received individual counseling on chronic diseases. Almost always, the health professionals who care of them, were mostly doctors followed by nurses. Based on the results presented, it is considered that the health services of medium complexity must undergone a more continuous dialogue with other attention level and focus on actions of health promotion and prevention. It is also recommended the necessity for qualified professionals to delivery health care to elderly and the implementation of protocols by a multidisciplinary health team, intending to provide better and continous care for the elderly with chronic diseases. The healthcare professionals who served them, were mostly physicians, followed by nurses. Through the results presented, it is considered that the medium complexity healthcare services need to perform a more continuous dialogue with the other levels of attention focusing attention to the health promotion and prevention actions. It is also recommended the necessity for qualified professionals to delivery healthcare for the elderly, in addition, a protocol implementation for the multidisciplinary health care team, to provide better care, and also the care continuity to elderly with chronic diseases

Determinação de Chaveamento para Recomposição do Serviço em Redes de Distribuição de Energia Elétrica em Média Tensão Através de Métodos Baseado em Parâmetros de Sensibilidade

The reconfiguration of a distribution network is a change in its topology, aiming to provide specific operation conditions of the network, by changing the status of its switches. It can be performed regardless of any system anomaly. The service restoration is a particular case of reconfiguration and should be performed whenever there is a network failure or whenever one or more sections of a feeder have been taken out of service for maintenance. In such cases, loads that are supplied through lines sections that are downstream of portions removed for maintenance may be supplied by the closing of switches to the others feeders. By classical methods of reconfiguration, several switches may be required beyond those used to perform the restoration service. This includes switching feeders in the same substation or for substations that do not have any direct connection to the faulted feeder. These operations can cause discomfort, losses and dissatisfaction among consumers, as well as a negative reputation for the energy company. The purpose of this thesis is to develop a heuristic for reconfiguration of a distribution network, upon the occurrence of a failure in this network, making the switching only for feeders directly involved in this specific failed segment, considering that the switching applied is related exclusively to the isolation of failed sections and bars, as well as to supply electricity to the islands generated by the condition, with significant reduction in the number of applications of load flows, due to the use of sensitivity parameters for determining voltages and currents estimated on bars and lines of the feeders directly involved with that failed segment. A comparison between this process and classical methods is performed for different test networks from the literature about networks reconfiguration

O masculino em revista: mídia, discurso e modos de subjetivação afetivos-sexuais

This dissertation has the thematic of the sexual affection of the masculine subjectivity within texts of Universo Masculino and Men‟s Health magazines as object of analysis. The central objective was to describe and interpret the theme on the masculine subjectivity in discourses about the affection of sexuality materialized in discourse practices in those magazines. The main point of the research matters how the discourse structures of texts in those magazines make it possible to comprehend the meanings produced about the masculinity nowadays. On the perspective of the thematic trajectory what consists the main aspect that concerns the leading of corpus in the research under the French discourse analysis, we have searched, in reports of those magazines, an arch-genealogy of masculinity, from a specific sexual-affection disposable of our mediate culture. The analytic trajectory enables us to conclude that the thematic trajectory about the sexual affection of the masculine subjectivity produces a semantic way that confirms hegemony and hetero-normative ideals, rather than what proposes new performances on the masculine subjectivity experiences. In its real effects, such mediate discourse practice pursues to link certain sexual affection knowledge to the male individual‟s lifestyle today, from the thematic choices, enunciation modalities and discourse strategies which are specific to the masculine media

Simulação computacional do escoamento em bombas de cavidades progressivas

The use of Progressing Cavity Pumps (PCPs) in artificial lift applications in low deep wells is becoming more common in the oil industry, mainly, due to its ability to pump heavy oils, produce oil with large concentrations of sand, besides present high efficiency when compared to other artificial lift methods. Although this system has been widely used as an oil lift method, few investigations about its hydrodynamic behavior are presented, either experimental or numeric. Therefore, in order to increase the knowledge about the BCP operational behavior, this work presents a novel computational model for the 3-D transient flow in progressing cavity pumps, which includes the relative motion between rotor and stator, using an element based finite volume method. The model developed is able to accurately predict the volumetric efficiency and viscous looses as well as to provide detailed information of pressure and velocity fields inside the pump. In order to predict PCP performance for low viscosity fluids, advanced turbulence models were used to treat, accurately, the turbulent effects on the flow, which allowed for obtaining results consistent with experimental values encountered in literature. In addition to the 3D computational model, a simplified model was developed, based on mass balance within cavities and on simplification on the momentum equations for fully developed flow along the seal region between cavities. This simplified model, based on previous approaches encountered in literature, has the ability to predict flow rate for a given differential pressure, presenting exactness and low CPU requirements, becoming an engineering tool for quick calculations and providing adequate results, almost real-time time. The results presented in this work consider a rigid stator PCP and the models developed were validated against experimental results from open literature. The results for the 3-D model showed to be sensitive to the mesh size, such that a numerical mesh refinement study is also presented. Regarding to the simplified model, some improvements were introduced in the calculation of the friction factor, allowing the application fo the model for low viscosity fluids, which was unsuccessful in models using similar approaches, presented in previous works

Estudo numérico de escoamento turbulento em padrão anular gás-líquido em dutos verticais

Multiphase flows in ducts can adopt several morphologies depending on the mass fluxes and the fluids properties. Annular flow is one of the most frequently encountered flow patterns in industrial applications. For gas liquid systems, it consists of a liquid film flowing adjacent to the wall and a gas core flowing in the center of the duct. This work presents a numerical study of this flow pattern in gas liquid systems in vertical ducts. For this, a solution algorithm was developed and implemented in FORTRAN 90 to numerically solve the governing transport equations. The mass and momentum conservation equations are solved simultaneously from the wall to the center of the duct, using the Finite Volumes Technique. Momentum conservation in the gas liquid interface is enforced using an equivalent effective viscosity, which also allows for the solution of both velocity fields in a single system of equations. In this way, the velocity distributions across the gas core and the liquid film are obtained iteratively, together with the global pressure gradient and the liquid film thickness. Convergence criteria are based upon satisfaction of mass balance within the liquid film and the gas core. For system closure, two different approaches are presented for the calculation of the radial turbulent viscosity distribution within the liquid film and the gas core. The first one combines a k- Ɛ one-equation model and a low Reynolds k-Ɛ model. The second one uses a low Reynolds k- Ɛ model to compute the eddy viscosity profile from the center of the duct right to the wall. Appropriate interfacial values for k e Ɛ are proposed, based on concepts and ideas previously used, with success, in stratified gas liquid flow. The proposed approaches are compared with an algebraic model found in the literature, specifically devised for annular gas liquid flow, using available experimental results. This also serves as a validation of the solution algorithm

Modelagem numérica de escoamento em padrão anular com transferência de calor e massa

Annular flow is the prevailing pattern in transport and energy conversion systems and therefore, one of the most important patterns in multiphase flow in ducts. The correct prediction of the pressure gradient and heat transfer coefficient is essential for optimizing the system s capacity. The objective of this work is to develop and implement a numerical algorithm capable of predicting hydrodynamic and thermal characteristics for upflow, vertical, annular flow. The numerical algorithm is then complemented with the physical modeling of phenomena that occurs in this flow pattern. These are, turbulence, entrainment and deposition and phase change. For the development of the numerical model, axial diffusion of heat and momentum is neglected. In this way the time-averaged equations are solved in their parabolic form obtaining the velocity and temperature profiles for each axial step at a time, together with the global parameters, namely, pressure gradient, mean film thickness and heat transfer coefficient, as well as their variation in the axial direction. The model is validated for the following conditions: fully-developed laminar flow with no entrainment; fully developed laminar flow with heat transfer, fully-developed turbulent flow with entrained drops, developing turbulent annular flow with entrained drops, and turbulent flow with heat transfer and phase change

Potassium supply to cotton roots as affected by potassium fertilization and liming

O algodoeiro (Gossypium hirsutum ) apresenta alta exigência de K e é muito sensível a baixo pH do solo. A maior parte do K chega às raízes das plantas por difusão no solo. Por existir interação do K com Ca e Mg, a calagem pode interferir no movimento do K no solo, afetando a nutrição da planta. O objetivo deste trabalho foi estudar o efeito de calcário dolomítico e de 0, 15, 30, 45 e 60 g kg-1 de K no suprimento de potássio às raízes do algodoeiro. As plantas foram cultivadas por 40 dias em vasos de 5 L contendo um Latossolo Vermelho-Escuro (68% de areia e 16% de argila). Houve um acréscimo na produção de matéria seca e na acumulação de K em função da adubação potássica. A intercepção radicular do K do solo foi também aumentada pela aplicação de K, mas não foi afetada pela calagem. O fluxo de massa e a difusão foram aumentadas linearmente com a aplicação de K até 60 mg kg-1, nos vasos com calagem. em vasos sem calagem a quantidade de K atingindo as raízes por difusão aumentou até 45 mg kg-1, decrescendo com a dose máxima de potássio. do mesmo modo, mais K entrou em contato com as raízes por fluxo de massa com a maior dose do nutriente. Isto aconteceu porque havia mais raízes finas nos vasos sem calagem e com a dose máxima de potássio. Com a diminuição da distância média entre as raízes, houve maior competição entre elas, culminando com a diminuição do K difundido até as raízes do algodoeiro.

Viabilidade técnica de uma rota não convencional para a produção de leite de cabra em pó em cooperativas do Rio Grande do Norte

Nowadays, Brazil has both the greatest goat herd and the greatest goat milk production of South America. The state of Rio Grande do Norte, located in northeast of Brazil, has an average year production of three thousand cubic meters of goat milk in natura. Part of this milk production is homemade and it comes from small farms, which unite in rural cooperatives created to encourage the production and implementation of industrial processes for preservation and processing of milk. Results presented by literature and obtained from preliminary essays in this thesis show that non conventional dryer of spouted bed with inert particles is able to produce powder milk from in natura milk (cattle or goat), with the same quality of spray dryer, however, operating at low cost. The method of drying in spouted bed consists of injecting milk emulsion on the bed of inert particles gushed by hot air. This emulsion covers the particles with a thin film, which dries and is reduced to powder during the circulation of inerts inside the bed. The powder is dragged by exhaustion air and separated in the cyclone. The friction among particles resulted from the particles circulation, encourages high taxes of shear in the thin film of emulsion, breaking the cohesive forces and making this process possible. Studying the drying process and the powder goat milk production in one unit of spouted bed with inert particles, seeing the development of a low cost technological route for powder milk production is the aim of this thesis. The powder milk produced by this route must attend the local demand of food industries which need an intermediate product to be used as a food ingredient (ice-cream, milk candy). In order to reach this aim, this thesis approaches the aspects related to physical, thermodynamics and physic-chemicals characteristics of goat milk, whose complete data are still inexistent in the literature. The properties of materials are of great importance to the project of any process which involves the operations of transportation of movement, heat and mass quantity, such as the dryers which operate in fluid dynamically active regime, like the spouted bed. It was obtained new data related to the goat milk properties in function of concentration of solids and temperature. It is also important to mention the study developed about the kinetic of solids retention in the bed of inert particles during the drying of goat milk. It was found more adequate processes conditions to the proposed technological route to be implemented in small and micro-industries, with simplifications in the system of milk injection as well as in the form of operation of the dryer. Important data were obtained for a posterior stage of this research which involves the v modeling, simulation, control and optimization of the process. The results obtained in this thesis, in relation to process performance as well as to the quality of produced powder milk validate the proposal of using the spouted bed dryer in the production of powder goat milk

Níveis crescentes de saturação por bases e desenvolvimento inicial de teca em um latossolo de textura média

Teak is a forest species of high commercial value, but the little knowledge on the behavior of this species in relation to soil acidity is an important factor that may limit its cultivation. The aim of this study was to evaluate the effect of high base saturation on the soil on the initial development of teak (Tectona grandis L.f.). The experiment was conducted in a greenhouse, in plastic containers with capacity of 50 liters. The experimental design was randomized, with five treatments and four replications. The treatments consisted of: natural saturation of the soil and the other treatments with 20 %, 40 %, 60 % and 80 % of saturation. Correcting the soil favored the growth characteristics of all evaluated plant teak. The liming positively affected the uptake of N, P, K, Ca, Mg, B, Cu and Fe, and the nutritional requirements of the species had the following order: N > Ca > K > Mg > P > S > Fe > Mn > B > Zn > Cu. Base saturations above 70 % showed higher plant development.

Slogans políticos em campanhas eleitorais no Rio Grande do Norte: a mídia na disputa ideológica.

To the observe the periods of electoral campaigns, we can realize sharply the abundance of political propaganda that announces the candidates, their campaign record, their proposed and everything that can carry them to the victory in the urns. The propaganda is today an essential tool in the votes dispute, in consequence of this, there is, in Brazil, the increasing participation of the Politics Parties in seminars of electoral marketing. They are varied strategies of the media used in the divulging of the candidacies, among them the slogan. Instigated by the explicit relation media/political, this work intends to investigate the ideologies (values) announced by the slogans of political propaganda that circulated in electoral periods. Thus, we base on the theory of the Circle of Bakhtin, who considers the statement as unit of the verbal communication, and that conceives the language as phenomenon dialogical, and, too, in the conceptions of alien words, social voices and dialogical relations formulated by the referred theory. We use, for better to comprehend, the slogan as strategy mediatic, of the classical study done by Olivier Reboul concerning the slogan; and, like starting point of a conception about ideology, studied John Thompson to comprehends the ideological phenomenon. Our corpus it constitutes of 14 political slogans announced in the campaigns for mayor of the cities in Natal and Mossoró, both located in Rio Grande do Norte s state, Brazil, in 1996, 2000 and 2004. For the analysis of these slogans, we consider the social-historical context in which were announced, being contemplated the linguistic and discursive aspect, according to the following methodological order: the identification of alien words (interdiscours); the social voices and the kinds dialogical relations established; and, finally, the ideology announced by the statement. This way, we can arrive to the conclusion that in the electoral context occurs a true ideologies war , in other words, in the political game of an electoral campaign, the slogans announces different values, which vary in several factors function, for example, the historicity, the subject that enunciates, the discursive positionings.
