Estudo comparativo da utilização do nitrogênio como fluido alternativo após a injeção de vapor

Currently, due to part of world is focalized to petroleum, many researches with this theme have been advanced to make possible the production into reservoirs which were classified as unviable. Because of geological and operational challenges presented to oil recovery, more and more efficient methods which are economically successful have been searched. In this background, steam flood is in evidence mainly when it is combined with other procedures to purpose low costs and high recovery factors. This work utilized nitrogen as an alternative fluid after steam flood to adjust the best combination of alternation between these fluids in terms of time and rate injection. To describe the simplified economic profile, many analysis based on liquid cumulative production were performed. The completion interval and injection fluid rates were fixed and the oil viscosity was ranged at 300 cP, 1.000 cP and 3.000 cP. The results defined, for each viscosity, one specific model indicating the best period to stop the introduction of steam and insertion of nitrogen, when the first injected fluid reached its economic limit. Simulations in physics model defined from one-eighth nine-spot inverted were realized using the commercial simulator Steam, Thermal and Advanced Processes Reservoir Simulator STARS of Computer Modelling Group CMG

Imagem corporal e fatores de risco em praticantes de caminhada da cidade do Natal-RN

Body image is the figure of our bodies built in our minds and the degree of dissatisfaction is often associated with risk factors identified by anthropometric measures. The purpose of this descriptive study was to evaluate the risk factors associated to morphological and functional variables associate to the perception of auto-image in middle-aged walkers of the south zone of the city of Natal. A hundred and thirty volunteers had been evaluated in four groups in function of the gender and age group. As measurement evaluations were used an auto-image perception questionnaire proposed by Stunkart of nine silhouettes numbered for both gender was applied; a weighing machine equipped with stadiometer for the body mass (kg) and stature (m) and the body mass index (kg/m2) that was calculated with base in measures of the body weight and stature and classified according to norms of the National Institute of Health (2000) as well as the systolic and diastolic blood pressure by a electronic digital device (DIGITRONIC). A metal anthropometric tape was used for the waist to hip ratio (WHR). It was used Analyses of variance (ANOVA) one-way, post hoc of Tukey and correlation of Spearman for the nonparametric data adopting the level of ρ≤ 0,05 for rejection of the null hypothesis. The body mass index indicated high factors of risk in the consisting groups. In all the groups were registered the desire to reduce their silhouettes. The body weight shows reduced when compared with the younger group in the male group of superior age group, while in the female group the inverse one occurs. The autoimage perception is associated with the classification of the waist to hip ratio in the female gender in the age group of the 50 to the 59 years and in the classification of the body mass index of all constituted groups. Significant associations had not been found for classification of the systolic and diastolic blood pressure in relation to the auto-image 41 perception. This thesis presents relation of interdisciplinarity and its contents have application in the fields of Physical Education, Medicine, Physiotherapy and Nursing

Risco de doença cardiovascular em mulheres com história de distúrbio hipertensivo da gravidez

OBJECTIVE: Preeclampsia is a disease that can lead to a high maternal and infant morbidity. Worldwide, the incidence of this disease is highly variable and there is no data on this disorder in the Brazilian population. This study aimed at determining incidence and risk factors in the hypertensive disorders during pregnancy in a neighborhood of Natal, in addition to observing the evolution of these disorders one year and five years after delivery. METHODS: Prospective cohort study to assess the outcome of pregnancies of 242 women who became pregnant between 2004-2007 in the neighborhood of Bom Pastor in the city of Natal, state of RN, Brazil. Five years after delivery, there was an active search of thirty-nine (39) women who became pregnant and had a hypertensive disorder during pregnancy and/or pré-eclâmpsia, out of the total of 242 participants in the initial study. We administered a structured questionnaire to obtain basic information about the current clinical situation of patients and occurrences of subsequent pregnancy and presence of hypertensive disorders during pregnancy. We also searched for information on the use of hypotensive drugs and contraceptives. The following characteristics were checked and recorded: a) current weight, b) blood pressure c) body mass index - BMI, and we collected biological samples (blood and urine) for measurement of biochemical parameters and evaluation of microalbuminúria. Finally, we monitored the ambulatory blood pressure (ABP), which uses the method of automatic measurement of heart rate, systolic and diastolic blood pressure and an average of the two for the period of 24 hours. RESULTS: Out of 218 women who completed the study, the incidence of hypertensive disorders was of 16.9% (37 out of 218), while the incidence of preeclampsia was 13.8% (30 of 218). Women with preeclampsia had a BMI (body mass index) averaged of 25.3 (± 4.8) while this ratio in normotensive women was of 23.5 (± 3.7), p = 0.02. The risk of preeclampsia rises with age (OR 1084 p = 0.0034) and with a family history of hypertension (OR 2.6 p = 0.01). The follow-up one year after delivery revealed that 50% of women with hypertensive disorders in pregnancy remained hypertensive. High BMI was also observed after 5 years of delivery. CONCLUSIONS: an elevated BMI, age above 35 years and excessive weight gain during pregnancy were associated with hypertension in the long term in patients with prior preeclampsia. History of preeclampsia increases the risk of chronic hypertension

Saberes da pesca: uma arqueologia da ciência da tradição

This essay presents and discusses knowledge obtained through tradition taken as knowledge built along generations, transmitted from mouth to mouth and everyday experiences result of a non-scientific knowledge based on observation and hints given by more experient generations. The referred icon used to develop such a discussion in this essay is fishing. We point out the knoledge which enables the fishermen, among other dominions, to: find out the fish and other animals feeding habits; find their way through by astral influence during night navigation and learn the tide flowing based on the moon cycle. On what comes to fishing knowledge, the research was organized based on a bibliographic study about several ways of fishing in the Northern, Northeastern, Southern and Southestern regions of Brazil. In the Northern and Northeastern regions, the field research was also focused. Having interviews, photographs and films as reference, this part of the research was divided into two parts: the first one situated in the Amazonian Region in na area called Baixo-Tocantins, in the State of Pará where we worked with fishermen in the small towns of Abaetetuba and Igarapé-Miri; and the second one was held in the Northeastern region of Brazil, in the State of Rio Grande do Norte, where we worked with fishermen on the Piató Lake, in the small city of Assú. We tarted discussing based on a descriptive study of the fishing techniques used, aiming to identify them as an ordered activity, differed and classified by knoledge obtained through the years, based on the relationship between man and Nature. Creativity, stimulated by human curiosity, is also discussed and shown as a result of various fishing journeys. The myths, as a component of the fishing world, especially those which describe the relationship between men and waters, also have an outstanding place. At last, two fishing techniques belonging to the research field reference, are also described and analysed under the focus of construction and systematization of the knowledge related to fishing. The theory approach is based on reflection upon the tradition knowledge discussed by Almeida (2001), Balandier (1997), Câmara Cascudo (1957, 2000, 2002) and Claude Lévi-Strauss (1976, 1987 and 1991). The essay is an exercise of knowledge production which defends the "relink" of knowledge, as Edgar Morin suggests when dealing with the sciences of complexity

Tear identitário:a prática docente em arte como conhecimento compartilhado

This investigative tissue is about the formation of identification processes of teachers and pedagogical practice of Art, in Teresina city. This search comprised the sum of the needs presented, agreed upon with the teachers engaged in the process, it was developed through the establishment of interactive environment Loom Team where collaboration and critical reflection were steering actions to promote the understanding of existing connections or relations within the processes of identifications and the pedagogical practice of Art. The tissue is formed by the polyphonic plot of the critical reflection of nine teachers of Art who engaged voluntarily and this investigation of formative nature and a production of knowledge. All these teachers have degree and the course of artistic education and especial qualification in Fine Arts and/or Drawing. The texture, which we denominated Identification Loom: The pedagogical practice of Art as share knowledge is (de) (re) construction of knowledge resulting from the critical reflection, in an environment of collaboration, which may have implications and ethical political attitudes in the pedagogical practice of the group. Within this context, we pose the following question: - How does the pedagogical practice in Art influence and/or be influenced by the identification processes of the teachers, and how do they interfere with the search and manifestation of the knowledge involved and the investment in professionalization? In view of this query, we make use of the cooperative investigation, having social history as theoretical reference and as analytic perspective of interactive and dialogical-reflexive processes. Thus, social historic theory, cooperative approach and pedagogical practice were the major components of the plot. The methodological texture counted on the threads of dialogical reflexion, of mediation and of collaboration. The conceptual formulation, the recording in videos of classes and the narratives of formations were the main threads of the analytic substrate of the investigation. With this articulation, theses threads appear as developers of processes leading to a major approximation of the thought on the identity/alterity dialectical pair of the participants involved. The language within this plot had a decisive importance in all the moments of the search of signification, embracing and connecting the identification/alterative processes, the pedagogical practice of Art and the knowledge shared. In such processes involving (de) (re) construction, one can notice a close correlation of the triad social identity, pedagogical practice and knowledge shared. For this reason, the vigotskian, guetmanovian and kopnian theoretizations were the major framework for the analysis of conceptual formulations; and, as for discourse analysis, Baktin and Orlandi were our masters. For these teachers, the experience shared throughout the process of this typology of tri-axial investigation focused the experience of many theoretical and practical assumptions. Such an experience enabled them to state that this, with collaboration, can make reflection on the practice a starting and promoting element, within the individual level of self-management, in addition to being a space of (de)(re)construction of meanings, of knowledge and of reinvention per se

O desenvolvimento profissional docente e a participação colegiado no Atheneu Norte-Riograndense

To investigate the relationship that exists among the educational participation of the school board and the teacher's professional development, starting from the analysis teachers of a public institution who teaches daily in the city of Natal. We focused the possible relationships between the teacher's action and their professional development, which includes the participation of the School board, considered by us as a collective space. To accomplish this research we used Interviews (KAUFMANN, 1996; SILVA, 2002) to analyze the nine participants, who are teachers' of the school board, and their oral speeches, considered as main references of our study. While trying to understand the reasons that led the teachers to choose her/his educational profession, we noticed the difficulty of recognition of the job of lecturing as a profession. This fact comes as an obstacle to the perspective of the teachers' professional development. In what he/she refers to the forms of the teachers' participation in the board and their meanings, we noticed in first place that the feeling of it belongs one of the decisive factors it can be considered actively for the teacher to announce of the actions colegiadas. This for them to want and they believe that that is the best road for if they develop better while professionals and consequently to improve the situation of the school. In second place we noticed that the school board represents, a place of articulation of the equality among all the ones that form the school community. So, we tried to understand how they happened to the collective actions in the school, how the teachers presented them in spite of what they know, how a collective action should be presented in the elements of fragility of that process that inhibit the development of the overall action. Finally, we questioned the elements that would contribute to the educational professional development; we noticed that the teachers present the competence, the ethics and professional valorization, as factors that contributed at the present time to their educational professional development

O programa Saúde da Família pelo olhar do Cirurgião-Dentista

This study tried to know the social representation of dentists surgeons about the Family Health Program (FHP). Where used as methodological instruments a semi-structured interview and direct observation of work process in tive towns that are part of the metropolis region ofNatal city. During the interview some aspects where broached, such as the reasons of dentists surgeons join the FHP, what are the implications ofthe introduction of this program in the everyday practice, what kind of activities are they practicing and what are those professional missing the most in the FHP. In the direct observation where take in account some aspects related to the physic structure of health units, its service organization and demand, relationship amongst dentist and other member of the team, and about patient receptiveness, when they arrives at health unit. This study also identifY the researches subject showing their age, sex, for how they are graduates, what are them specialty and for how long they work for the FHP. The data had been analyzed through the analysis of content of Bardin5. The dentists depict the FHP for the change in assistance model through the preventive proposal of social work that makes possible to work with an ample concept of health. However what makes the FHP more attractive to dentists is the salary questiono The creation of bonds whit the community and the work whit groups and in team had been the main occurred changes in the daily one of the pratices ones of these professionals. The principal activities executed for these professionals inside of the new strategy of assistance in oral health are the carried trough preventive activities achieved in health units and social area. To them, the absence of institutional support and the employment of only one dentist for each team it is one the main point of strangling. There is no doubt that FHP is new strategy and that it is need a better integration amongst the professional, the institution

As pessoas com deficiência no mercado de trabalho: expressão das desigualdades sociais

This work was developed in the extent of the Post Graduation Program in Social Service of the Federal University of Rio Grande do Norte. It talks about the process of inclusion of the disabled people in the Job market in Mossoró-RN, bringing for the academic debate relevant thematic for the Brazilian society, for the profession of Social Service and similar areas and for the people with deficiency. It has the objective to apprehend the determiners that make possible the process of the disabled people's inclusion in the Job market in Mossoró, having as parameter the National Politics for the Integration of People Bearers of Deficiency. The critical theoretical perspective is backed in Marx's ideas for the understanding concerning the work, as well as in Pochamann, concerning the job market, regarding the exclusion/inclusion category is based in Martins, Yasbek and Sposati and on deficiency in the National Politics for the Integration of the Disabled People. The research is of qualitative nature and it took as subjects 26 (twenty-six) people, being 09 (nine) people with deficiency, inserted in the formal job and regulated market, and 17 (seventeen) managers of private companies and public institutions of the city of Mossoró-RN. For the collection of data we used techniques of nonsystemic observation, semi-structured interview and documental analysis. The results of the research mark that any modality of the human workforce used in the current context, they are functional to the capitalism and they move forward towards exploration, alienation and subordination of the work to the capital; the National Politics for the Integration of the People with Deficiency expresses and reproduces the contradictory dynamics of the class society, it reflects the neo liberal shades through the selectivity and of the articulation among the federated beings and organizations of the civil society for its operational system; there is a misproportion between the percentages of the quotas and the amount of people with deficiency inserted in the job market, just corresponding to a tiny numeric magnitude; the developed activities are of low social status and it is expressive the amount of workers that receives between one and two minimum wages. These data drive us to infer that the mentioned politics make possible, partly, the inclusion of the disabled people in the job market, though, such inclusion is executed in the selective or focused dimensions, marginal, precarious and unstable

Impacto do Programa Saúde da Família sobre indicadores de saúde da criança em municípios de grande porte da região Nordeste do Brasil

The present study carried out in the context of the Baseline Studies of the PROESF was aimed at evaluating the impact of the Family Health Program (PSF) on indicators for child health in cities with more than 100,000 inhabitants in the Brazilian Northeast. Four cities were investigated. In each one, twenty censual sectors were selected randomly from areas covered by the PSF and compared with twenty sectors selected from areas not covered by the PSF on the basis of socioeconomic criteria. In most cases, no significant differences were found between the areas covered and not covered by the PSF. The only difference found was a significantly lower rate of hospital admissions due to diarrhea but this was on account of the Program of Community Health Agents. The PSF exerted no additional effect on the reduction of this indicator. It was also observed that the way by which the program is implemented in each city interferes directly in the results. Thus, there is no basis for considering the PSF per se ineffective or not differing from other programs with regard to its health care patterns. An evaluation of the PSF would necessarily have to include an analysis of the way the program is implemented and conducted in each case, besides considering its general socioeconomical and political characteristics.
