The aim of this work is to use a new technology in the treatment of produced wastewaters from oil industry. An unit for treat produced waters called UTMDIF, was designed, installed and operated in an industrial plant for treatment of effluents from oil industry. This unit operates by means of the method of separation of phase inversion and can become a promising alternative to solve the problem of oil/water separation. This method constitutes the basis of the working of a new design of mixersettler of vertical configuration which occupies small surface area. The last characteristic becomes specially important when there is limitation on the lay-out of the plant, for example, over maritime platforms to explore oil. This equipment in a semi-industrial scale treats produced wastewaters contaminated with oil at low concentrations (ranging from 30 to 150 mg/L) and throughputs of 320 m3/d (47,4 m3 m-2 h-1). Good results were obtained in oil/water separation which leads to the necessary specification to discharge those wastewaters. Besides, the non dependence of the efficiency of separation in spite of the salinity of the medium becomes the equipment an attractive new technology to treat wastewaters containing oil at low concentrations

Cette recherche a pour but d approfondir des études qui mettent en lumière des particularités inhérentes au processus de l écriture fragmentaire. Notre intérêt pour ce thème provient de la poétique fragmentaire du Le livre de l intranquillité composé par Bernardo Soares, assistant de notaire et sémi-hétéronime de l écrivain Fernado Pessoa. Notre approche de ce genre textuel commencera par une méthodologie comparative qui nous donnera des notions pour que nous puissions établir quelques rapports de ressemblances et différences entre fragments, maximes, aphorismes et réflexions dont le corpus littéraire sera le journal intime de l intranquilité soarianne, ainsi que la fragmentation du simulacre d auteur au cours des années pendant lesquelles le Livre a été écrit. Le livre de l intranquillité lance des « pulvérisations » réflexives, lesquelles demeurent actuelles, étant donné que le processus de l écriture fragmentaire semble être toujours dans un mouvement constant et, donc, dans l ambiance du à venir. À partir de cela, nous avons passés pour quelques entraves pour essayer d établir une définition pour ce qui serait l écriture fragmentaire. Nous chercherons des points d intersection visant à établir des paradigmes pour obtenir des notions plus précises sur ce genre textuel, concernant les maximes, aphorismes et sentences refléxives.

Introduction: Falls among older adults is a public health problem, therefore it is necessary preventive actions, however the adherence is the major problem faced by practitioners and researchers working on falls prevention programs. Objective: To evaluate the variables related to the adherence to falls prevention programs among the elderly enrolled in a Basic Health Unit (BHU). Methods: Was performed an observational cross-sectional analytical study. All elderly registered in a BHU and able to ambulate independently were invited to participate in a falls prevent program. The Elderly who Adhered to the Program (EAP) were evaluated at BHU; and the Elderly Not Adhered to the Program (ENAP) were identified and assessed at home. The assessment for both groups was performed using an evaluation form containing personal data, measures and clinical scales to assess cognitive status, balance, mobility, fear of falling, handgrip strength. Data were analyzed with SPSS 20.0. In addition to this assessment, the ENAP underwent a semi structured interview, in which we used the qualitative approach based on the figure of the Collective Subject Discourse. Results: The study included 222 elderly, 111 EAP and 111ENAP, most aged between 70 and 79 years (48.2%), female (68.5%), married (52.3%) and illiterate (47.7%). Consolidated as protective factors for adherence, worst rates of physical activity (p = 0.001), balance (p = 0.010) and cognition (p = 0.007). The interview of ENAP identified two themes: "Local implementation of programs for the prevention of falls" and "Relationship between BHU and the elderly health care," and found that the elderly who did not adhere were unable to displace and did not mention that primary care programs are related to health care in elderly. Conclusions: Elderly who do not adhere to the program differ from elderly who adhere as worst indices of cognition, balance and physical activity which implies greater risk of falling; and they were unable to participate in falls prevention program and by to be caregiver and showed displacement difficult

Family Health Strategy (FHS), founded in 1994 has appeared to play a strategic role in the SUS construction and consolidation. It has reaffirmed its Principles and Guidelines and has elected family as core of attention. The principle that has guided the work concerns the quality of the relationship between professional and family. Thus, the FHS has the family as a subject of health-disease process, and relations with its own characteristics and can be partners in building their health and improvement of quality of life of its members and the entire community. This study aims to characterize the surgeon-dentist (SD) working process in the family health strategy, from the knowledge of the SD integration with other team members; organization of services; development of shares, changes perceived by SDs, as well as knowing the surgeon-dentist profile who is part of this strategy. The collecting tool used was a semi-structured questionnaire, in which participated 30 professionals. As for profile, most professionals were women, completed the graduation in public university and did not have any training to work by joining the FHS. Almost all have other public or private working ties. They often carry out activities with students, and occasionally do home visits. In relation to team work, in activities such as home visits, school health, community activities, among others, they sometimes seek the cooperation of other members. The way of accessing for users in the most part has occurred through the schedule. The most frequently activities made to the Centro Especialidades Odontológicas (CEO), are in Endodontics and Prosthesis. The majority of them participate in team meetings, but they do not have frequency set to happen. As for the planning and programming of activities to be conducted, most said that individually develops them. Concerning the performance of their duties, most reported being satisfied, but that improvements could happen. Besides, they reported improvements in dental care following the inclusion of SD in the FHS in various aspects, such as access, organization, humanization, care and oral disease prevention. The professionals had poor integration with other team members, in addition to have a profile to more individualistic work, a fact seized by way of development and planning of actions. They work the actions in individual and curative way, in detriment promotion and collective ones. They work humanization, definition of territory and adscript population. Thus, it is concluded that the working process developed by SDs, includes the part which is advocated by FHS. This points out to a greater undertaking of this process aiming to detect the weakness met in order to reach the potential that the FHS represents in organization of basic attention

This study aims to analyzing the implementation of the Matrix Support proposal with professionals of Substitutive Services in Mental Health in the city of Natal/RN. The Matrix Support (MS) is an institutional arrangement which has been recently adopted by the Health Ministry, as an administrative strategy, for the construction of a wide care net in Mental Health, deviating the logic of indiscriminate follow-through changed by one of co-responsibility. In addition to this, its goal is to promote a major resolution as regards health assistance. Integral attention, as it is intended by the unique health system, may be reached by means of knowledge and practices interchange, establishing an interdisciplinary work logic, through an interconnected net of health services. For the accomplishment of this study, individual interviews of semi-structured character were used as instrument, with the coordinators and technical staff of the CAPs. The data collection was done in the following services: CAPS II ( East and West) and CAPS ad ( North and East), in the city of Natal/RN. The results point out that the CAPs to initiate of the discussion the process in the implementation of the MS aiming, to promote the reorganization and redefinition of the flow in the net, thus not acting in a fragmented way. Nevertheless, there is no effective articulation concerning the basic attention services, there is a major focus of the attention in mental health on the specialized services, little insertion in the territory and in the everyday life of the community

Coexisten, en el universo académico, prácticas curriculares obligatorias y no obligatorias que pueden ser remuneradas o no. Delante de la constatación de lagunas en la concepción, gestión y operacionalización de las prácticas no obligatorias remuneradas, escogimos este tema como objeto de nuestra investigación, tratando de analizarlo en el contexto de los cambios sociohistóricos contemporaneos y su influencia en la cualidad de la formación profesional del estudiante de la carrera de Servicio Social. Este estudio tiene como ¨locu¨ de investigación la Facultad de Servicio Social del Estado de Rio Grande del Norte (FASSO/UERN). Este estudio se caracteriza por la adopción de una perspectiva de análisis cualitativa, con la expectativa de develarlo mucho más allá de lo que se muestra en su aparecncia. Para esto, realizamos revisión de literatura, análisis de documentos, observación asistemática y entrevistas con estudiantes y profesionales de las entidades que ofrecen prácticas a los estudiantes. Además se incluyó, en los procedimientos metodológicos, la aplicación de encuestas y conversaciones informales. Constatamos la existencia de lagunas en el desarrolllo de las prácticas no obligatorias remuneradas, ocasionadas por la ausencia de supervisión y por la inclusión de pasantes en sectores y/o actividades desvinculadas de su futura profesión. La investigación nos permitió desvelar situaciones en las que la oferta de plazas ocurre en detrimento de la contratación de empleados, lo que configura un distanciamento de este componente curricular del área de formación profesional, desvirtuando su carácter educacional. Cientes de la coexistencia contradictoria entre situaciones ventajosas y problemáticas en las prácticas no obligatorias remuneradas para el proceso de formación profesional de los asistentes sociales, concluimos que esta modalidad de práctica cuando vinculada a la intervención de la facultad y bajo la supervisión de asistentes sociales, independiente de sus implicaciones en los intereses del mercado, potencializa el desarrollo de competencias y habilidades intrínsecas al proceso de formación profesional; pero si distanciada del área de formación y/o sin el debido acompañamiento didáctico-pedagógico establece poca o ninguna relación con la formación de los asistentes sociales. Pero, incluso distanciadas del ejercicio y de la formación académica en el área de servicio social y/o (llenas de aspectos frágiles) llenas de fallas en el proceso de enseñanza y aprendisaje, estas experiencias ejercen profunda influencia en la formación de los asistentes sociales, pudiendo fragilizar el compromiso con el proyecto ético-político, diseminar el aspecto subalterno de la profesión y hacer confuso y conflictivo el proceso de construcción de la identidad profesional. En este sentido, las inversiones de capital para reducir los gastos con mano de obra, las dificultades vividas por las universidades públicas brasileñas para garantizar la cualidad de la enseñanza delante de la insuficiencia de recursos humanos y materiales y la desvalorización de los componentes no obligatorios del proceso de formación profesional de los asistentes sociales, son factores que obstaculizan el reconocimiento y la materialización del potencial didáctico-pedagógico de las prácticas

This paper presents the survey results: PROCEDURE FOR WORK IN HEALTH: an analysis of working conditions of social workers in hospitals. Analyzes the inclusion of social workers in work processes in healthcare, specifically in the public hospital, from the objective conditions of work, according to which materializes professional action. The aim is to understand them from the point of view of its relationship with users and other health professionals through the privatization of health, which prevents the Unified Health System (SUS), limiting the operation of the services and the guarantee of rights. The approach to the reality studied was through theoretical and methodological procedures based on the qualitative and quantitative research, focusing on documentary research, observation, semi-structured interview and the theoretical foundation. It is observed that the inclusion of social workers in this context arises from the demands derived from expressions of social issues, "raw material" of professional work, and the gaps resulting from contradictions in the process of rationalization / reorganization of the SUS, meaning that the needs the population are confronted with the content and form of organization of services. At the hospital, the professional actions are developed through the shift, space contradictory clash between the collective and individual, in which individual activities are prioritized and ad hoc unplanned and reduced to the solution of "problems" of users, through actions assistance in an emergency and bureaucratic. These findings emphasize the inadequacy of space and lack of minimum conditions of service to users, which undertakes the professional with regard to ethical and political principles of the profession, since it is the responsibility and duty of the social guarantee the secrecy and privacy of users what is revealed during the process of professional intervention. The professional social workers is permeated by the diversity of skills and competence; lack of planning activities, by incorporating the institutional discourse at the expense of professional goals, by knowing the Code of Professional Ethics, for small number of professionals, the increasing number informality; by poor working conditions and wages; by discouraging research and participation in social policy councils, as well as professional training

Can be declared that throughout the historical trajectory of the Brazilian Social Work, the men in the Social Work profession, women in the Social Work profession in his/her professional activity, present an educational dimension that runs through various social and occupational spaces, particularly in the area of Social Assistance Policy. Based on this premise, this present Dissertation, problematize the educational dimension present on the interventional process, in Social Work on the ambit of the Social Assistance Policy in Natal / RN city Brazil in the contemporary scene. Having thus, specific objectives that orientate the research of the interventional process of Social Work in the social assistance policy, analyzing of the apprehension of Social Work professionals on the educational dimension, in their daily work professional and the verification of the relationship between the educational dimension, to the professional action of both men in the Social Work profession and women in the Social Work profession and the concretization of social rights on the ambit of the social assistance policy. In this sense, the theoretical and methodological procedures used for this research, are substantiated on a critical-dialectical perspective and a qualitative and quantitative approach, from of the application of field research, of the non-participant observation, of the semi-structure, of the review of literature bibliographic and documental. Thus, considering that both women in the social work profession and men in the social work profession are an organic intellectuals who in their daily professional work promotes an intellectual and moral reform of their users, the results of this research, synthesize and show that the educational dimension in both professional work and social assistance, which have partner-historics, whose imbrication allows, contradictorily, by a side, a reaffirmation of the dominant culture, and by other side, a direction linked to the construction of an emancipatory culture in the pursuit of the materializing of social rights and a new sociability

In the context of Software Engineering, web accessibility is gaining more room, establishing itself as an important quality attribute. This fact is due to initiatives of institutions such as the W3C (World Wide Web Consortium) and the introduction of norms and laws such as Section 508 that underlie the importance of developing accessible Web sites and applications. Despite these improvements, the lack of web accessibility is still a persistent problem, and could be related to the moment or phase in which this requirement is solved within the development process. From the moment when Web accessibility is generally regarded as a programming problem or treated when the application is already developed entirely. Thus, consider accessibility already during activities of analysis and requirements specification shows itself a strategy to facilitate project progress, avoiding rework in advanced phases of software development because of possible errors, or omissions in the elicitation. The objective of this research is to develop a method and a tool to support requirements elicitation of web accessibility. The strategy for the requirements elicitation of this method is grounded by the Goal-Oriented approach NFR Framework and the use of catalogs NFRs, created based on the guidelines contained in WCAG 2.0 (Web Content Accessibility Guideline) proposed by W3C

Intensive production of tilápias, in cages or net tanks, has been proposed as an alternative to increase fish production, that would generate income and offer animal protein in different tropical and subtropical countries. However, this system of production enriches the aquatic environment with nutrients, principally nitrogen and phosphor derived from the dejections of the metabolism of food and eventual food surpluses consumed by the fishes; the alimentation of the fishes in this production modality is dependent on fish food. The emission of these nutritions in levels above the limit that the system is capable metabolize can provoke a phenomenon called eutrofization, putting in risk the quality of water for public and for fish production activities. In this context the work had as a goal to evaluate the trófico state of the four reservoirs for intensive production of tilapias in net-tanks, in other words, he maximum fish production that the reservoirs are able to hold, keeping the desired quantity of nutrient concentrations in water for public use. The results of the four ecosystems in the Boqueirão de Parelhas reservoir showed that it s possible to have an intensive production of tilapias in net tanks, in this environment the annual average concentration of phosphor, was below the considered critical limits to deflagrate the process of eutrofization in semi-arid regions. The carrying capacity of the Boqueirão de Parelhas reservoir depends on the conversion of the feeding facts and phosphor content in the food but it should vary between 100 and 300 tons per year over a variation in the conversion feeding factor of 1,7 to 2,0:1 and a variation in the P in the food of 0,7 to 0,9%

Ocupando uma área de 665,7km2 (equivalente a 1,25% da superfície estadual), o Município de Lajes até o início do século XX era um pequeno distrito do Município de Jardim de Angicos, localizada na Região Central do Estado do Rio Grande do Norte. Quando decretado município, em 1914, Lajes tornou-se o principal entreposto comercial do estado, uma vez que sua posição geográfica a colocava como rota principal entre os municípios produtores de mercadorias e a capital do estado, Natal, situada a 125km a Leste do município. Esta confortável posição de entreposto comercial cristalizou-se com a construção da estrada de ferro Sampaio Correia, em 1919, que agilizou o escoamento das mercadorias advindas do interior com Natal, principalmente o algodão, que até a década de 1980 era a principal fonte econômica do Estado do Rio Grande do Norte. Com a crise do algodão e a construção de estradas ligando diretamente os mercados produtores com a capital, Lajes perde a condição de principal entreposto comercial do estado, e sua economia entra em decadência. Vastas áreas de caatinga onde outrora se plantava algodão foram abandonadas, deixando os solos destas terras livres para a ação erosiva dos ventos e das torrenciais chuvas de outono. Situada numa porção do estado que sofre direto sombreamento das escarpas da Serra do Feiticeiro, o município de Lajes tem se configurado como um importante laboratório para o estudo da desertificação no Estado do Rio Grande do Norte. A partir de uma análise Geossistêmica, procurou-se diagnosticar o atual quadro da desertificação nesta porção semi-árida do estado. Para tanto, utilizou-se os métodos quantitativos de análise, dentre eles os métodos desenvolvidos durante a elaboração do Pan Brasil, com a construção dos Balanços Hídricos e Índices de Aridez do município. Os dados referentes aos índices de aridez de Lajes apontam para um profundo processo de ressecamento do ar na região, corroborando inclusive com os dados referentes ao aquecimento global divulgados pelo IPCC (Intergovernamental Panel on Climate Change) no mês de fevereiro de 2007

E utrophication in continental aquatic ecosystems and the following deterioration of water quality are some of the greatest problems to be solved in this century. Due to their own peculiarities reservoirs from semi - arid regions constitute a great challenge to water management because of their greater vulnerability to eutrophication process. I dentification of biolo gical community components that may be used as bioindicators is important to allow an early detection of adverse changes, and also to provide subsidies for management and conservation actions. The aim of the present study is to evaluate the potential of zo oplankton community as bioindicator of the trophic state of two reservoirs belonging to the Piranhas - Açu basin, RN, Brazil: Boqueirão de Parelhas and Passagem das Traíras. Monthly sampling s of both systems were carried out in both systems during the period of January to December. Measurements were performed for temperature, pH, dissolved oxygen and water electrical conductivity besides water samples collection for nutrients, suspended solids, chlorophyll - a and zooplankton analyses. T axonomic composition of zooplankton , density and biomass were analysed. Trophic state index, ABC curves , W statistic and the Calanoida: Cyclopoida ratio were also obtained. The results evidenced that Boqueirão de Parelhas reservoir was a mesotrophic sy stem, and Passagem das Traíras r eservoir was eutrophic. In both reservoirs zooplankton community had low species richness, mostly constituted by tolerant species which have wide geographical distribution, as well the dominance of the rotifers Brachionus havanaensis , B. calyciflo rus and Keratella tropica ; of the calanoid copepods Notodiaptomus cearensis and N. iheringi ; cyclopoid copepod Thermocyclops decipiens, and of the cladocerans Ceriodaphnia cornuta and Diaphanosoma spinulosum . Among the biological indices the ABC curves fo r the zooplankton community indicated a moderate dis turbance in both reservoirs, th e Calanoida: Cyclopoida ration indicated not impacted environments , e xcept during the end of the study to the reservoir Passagem das Traíras . It was concluded that the indices used are good indicators of disturbance and alteration in the community, however they are not good indicators for monitoring the trophic state of the studied reservoirs due to the simultaneous occurrence of other factors selecting species, as the c oncentration of ions and high turbidity, which are part of the reservoir characteristics of semiarid.

The objective was to understand the process of care in the perception of hospitalized children with cancer. This is a descriptive study of qualitative approach. Data were collected between the months of October 2013 and January 2014, through photographic records and semi-structured interview consisting of questions relating to the identification of age, sex, diagnosis and length of stay and a script of questions related to the recorded pictures. Eight children were included aged between six and twelve who were admitted to a pediatric oncology sector, located in the city of Natal / RN. The criteria used in the sample were: being hospitalized for cancer treatment; and present favorable physical conditions for carrying out the data collection. For the treatment of collected material was used content analysis, thematic modality. The study followed the ethical and legal principles governing scientific research with human beings and took place with the approval of the project by the Ethics and Research Committee of the Northern League Riograndense against Cancer, with opinion registered under number 329 015 and CAAE 16097613.9.0000.5293. According to the results it was found that, for the child, the care happens through technical activities, such as making procedures and the use of personal protective equipment, as well as through the dialogic relationship, which favors the establishment of confidence in care professional. Caring also means developing activities that promote well-being, the fun and the social and cognitive development, highlighting thus the playful, during hospitalization, as an auxiliary tool in the care process. During hospitalization, the child identifies two individuals responsible for their care, accompanying family and professional, and nursing professionals the most cited in moments of care. , Also of note, the promotion of care, in the perception of the child related to the infrastructure of the institution, environmental cleaning, personal hygiene, the medicalization and the food. It is concluded that care understood by the child, whilst still maintaining relations with the biomedical model, points to a new perspective that should consider the biological, social and psychological of acquiring cancer without unlink them of the development child. 9 Moreover, we see the child as an active social actor in this process, and therefore needs to be heard and answered their needs

This study offers an analytical approach in order to provide a determination of the temperature field developed during the DC TIG welding of a thin plate of aluminum. The non-linear characteristics of the phenomenon, such as the dependence of the thermophysical and mechanical properties with temperature were considered in this study. In addition to the conductive heat exchange process, were taken into account the exchange by natural convection and radiation. A transient analysis is performed in order to obtain the temperature field as a function of time. It is also discussed a three-dimensional modeling of the heat source. The results obtained from the analytical model were be compared with the experimental ones and those available in the literature. The analytical results show a good correlation with the experimental ones available in the literature, thus proving the feasibility and efficiency of the analytical method for the simulation of the heat cycle for this welding process.

Esta investigación parte del interés en la comprensión de la cuestión de los conocimientos enseñanza, precisamente el conocimiento necesario para el profesor profesional relacionada enseñanza, es decir, cuáles son los conocimientos, los profesores a construir en su contexto de trabajo. Somos conscientes de que el escenario es un momento de importancia fundamental para el desarrollo del conocimiento inicial de la profesión docente y la construcción de la identidad profesional. Tratando de entender estos aspectos nos preguntamos: ¿Qué conocimientos de los futuros profesores construyen o se movilizan durante la práctica docente desarrollado en el escenario? Nuestro objetivo es entender el proceso de identidad de estudiantes Pedagogía UFRN e identificar el conocimiento construido sobre la práctica docente desarrollada durante el entrenamiento supervisado de dicho curso. Se trata de una investigación cualitativa, y tenía como instrumento de recolección de datos, entrevistas semi-estructuradas con diez (10) en 2014.1 académicos que habían ocupado la práctica docente en el entrenamiento supervisado. Las entrevistas fueron sometidas a análisis de contenido propuesto por Bardin (2011). Como marco teórico, los autores también apoyan en tan Tardif (2012), Pimenta (2012), Nóvoa (1995), Perrenoud (2002), entre otros, se trata de la enseñanza de conocimientos dentro de la profesionalización docente, estableciendo relación con el proceso de identidad. Los resultados indican que, en lo que respecta a la identidad profesional, estudios teóricos en el curso de formación inicial, junto con las experiencias vividas en su mayoría en el escenario, contribuyeron a cambiar lo que los estudiantes sabían acerca de ser un maestro. Por lo tanto, algunos han fortalecido la identidad con la profesión, mientras que otros han renunciado a invertir en la carrera docente. En cuanto a conocimiento construido, se puede decir que los alumnos se dan cuenta de la pluralidad de conocimientos necesarios para una profesión tan compleja como la enseñanza. Sin embargo, a modo de síntesis, este conocimiento a su vez a aprender a planificar lecciones considerando las necesidades de los estudiantes y su contexto social. Los participantes declaran saber cómo llevar a cabo la mediación del aprendizaje a través del diálogo y actividades bien estructuradas y afecto contribuye al aprendizaje. En este sentido, se entiende que las construcciones de conocimiento en el escenario se articularon a reflexionar sobre su propia práctica e indican lo que era más importante en términos de aprendizaje de la percepción de los estudiantes. Sobre la base de este entendimiento, creemos que los momentos de observación (primero paso en el escenario) y el muy regencia podrían considerarse en el proceso de formación, para que los estudiantes se registre el aprendizaje proporcionado por la práctica. Es necesario, por tanto, que los estudiantes investiguen su propia actividad pedagógica, convirtiendo sus conocimientos en una continua construcción y reconstrucción de sus identidades a partir de la importancia social que conceden a la enseñanza.
