A ado??o de uma dieta equilibrada, que inclua alimentos com potencialidades funcionais, associada ? pr?tica de atividade f?sica regular s?o alternativas atualmente preconizadas. Dentre os alimentos com potencialidades funcionais est? o pequi (Caryocar brasiliense), muito utilizado no Brasil para fins aliment?cios, terap?uticos e cosm?ticos, e que apresenta como componentes majorit?rios lip?deos ricos em ?cidos graxos monoinsaturados, fibras e carotenoides. Estes componentes isoladamente, apresentam alguns efeitos semelhantes ao exerc?cio f?sico aer?bio sobre a redu??o de diversos fatores de risco para DCNT, de forma que associados podem fornecer efeitos potencializadores sobre a redu??o desses fatores de risco. Assim, este estudo teve como objetivo avaliar, em ratos, efeitos biol?gicos advindos da ingest?o da polpa de pequi associada ? pr?tica de exerc?cio f?sico aer?bio regular (EFAR), especificamente sobre vari?veis relacionadas ao crescimento, par?metros cardiovasculares, do metabolismo glic?dico e lip?dico, sobre a histomorfometria duodenal e o estado redox celular. O protocolo experimental consistiu de quatro grupos (n=8) de ratos Wistar machos: CS - animais que receberam ra??o; CT - receberam ra??o e EFAR; PS - receberam ra??o suplementada com polpa de pequi (3,26/100g = +50% do conte?do lip?dico da ra??o) e PT - receberam ra??o suplementada com polpa de pequi e EFAR. O EFAR foi realizado em piscina, em intensidades e cargas progressivas, e a dieta fornecida ad libitum durante quinze semanas. A ingest?o alimentar e o peso corporal foram monitorados durante o per?odo experimental para os c?lculos da ingest?o alimentar e cal?rica, do ganho de peso e dos coeficientes de efici?ncia alimentar (CEA) e energ?tica (CEE). As fezes foram coletadas nas ?ltimas 72 horas do experimento. A press?o arterial sist?lica (PAS) e a frequ?ncia card?aca (FC) foram aferidas no in?cio e na ?ltima semana do experimento. No ?ltimo dia do protocolo, os animais foram eutanasiados e foram determinados: (a) o comprimento da t?bia esquerda; (b) o peso absoluto e relativo do f?gado, p?ncreas e cora??o e da gordura das regi?es epididimal e retroperitoneal; (c) a concentra??o plasm?tica de colesterol total (COL), lipoprote?na de alta densidade (HDL), triglicer?deos (TG), glicose, insulina, o ?ndice HOMA-IR e o ?ndice aterog?nico; (d) a concentra??o hep?tica e fecal de COL e TG; (e) a umidade e o pH fecais; (f) a capacidade antioxidante total ? Ferring Reducing Antioxidant Power plasm?tica, e dos tecidos muscular (s?leo), hep?tico e card?aco; (g) os n?veis de peroxida??o lip?dica - Thiobarbituric acid reactive substances nos tecidos hep?tico, muscular e card?aco; (h) a atividade da enzima super?xido dismutase nos tecidos hep?tico e muscular; (i) a atividade da enzima catalase nos tecidos hep?tico, muscular e card?aco. Foram coletadas amostras de tecido duodenal para an?lises histomorfom?tricas. Observou-se que a associa??o da ingest?o da polpa de pequi ao EFAR n?o influenciou de maneira significativa no crescimento (ingest?o alimentar e cal?rica, peso corporal, CEA, CEE, peso de ?rg?os, comprimento da t?bia), na PAS e FC, na glicemia, na insulinemia ou no ?ndice HOMA-IR. Contudo, reduziu a deposi??o de gordura visceral (epididimal e retroperitoneal). Tamb?m n?o houve diferen?as entre os tratamentos para as concentra??es plasm?ticas de COL, HDL e TG. Contudo, a associa??o da ingest?o da polpa de pequi ao EFAR promoveu menor deposi??o hep?tica e maior excre??o fecal de lip?deos, al?m de preservar melhor a altura das vilosidades intestinais e promover aumento da profundidade das criptas. N?o houve impactos significativos dos tratamentos sobre as vari?veis relacionadas ao estado redox celular, somente a atividade da catalase foi aumentada pela associa??o entre EFAR e polpa de pequi no f?gado. Os efeitos fisiol?gicos advindos da ingest?o da polpa de pequi associada ao EFAR relacionados ao menor ac?mulo de lip?deos na regi?o visceral e f?gado, com a maior excre??o desses lip?deos, aumento da profundidade das criptas sem preju?zos ? estrutura do intestino e aumento da atividade antioxidante end?gena, bem como a aus?ncia de efeitos prejudiciais sobre as demais vari?veis analisadas, faz dessa associa??o uma poss?vel estrat?gia para redu??o do risco para DCNT e manuten??o da sa?de. / Disserta??o (Mestrado) ? Programa Multic?ntrico de P?s-gradua??o em Ci?ncias Fisiol?gicas, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2014 / ABSTRACT Given the increasing number of chronic non-communicable diseases (NCDs) affecting health and economy of countries, alternatives on reducing risk factors for these diseases are urged. A balanced diet that includes foods with functional properties associated with regular physical exercise is currently recommended. Among foods with functional potential, is pequi (Caryocar brasiliense), wich is widely used in Brazil for food, cosmetic and therapeutic purposes. It has as its major components, lipids high in monounsaturated fatty acids, fiber and carotenoids. These components have some similar effects as aerobic exercise on the reduction of several risk factors for NCDs, turning its association into a potential strategy for fighting NCDs risk factors. Therefore, this study aimed to evaluate, in rats, biological effects from the intake of pequi pulp associated to regular aerobic exercise (RAE), specifically on growth-related, glucose and lipid metabolism and cardiovascular variables, on duodenal histomorphometry and cellular redox state. The experimental protocol consisted of four groups (n = 8 ) of male Wistar rats: CS - animals fed chow; CT - animals feed chow and RAE; PS - animals feed chow plus pequi pulp (3.26/100g = +50 % of the lipid content of chow) and PT - animals feed chow plus pequi pulp and RAE. The RAE was held in pool at intensities and progressive loadings, and the animals were fed ad libitum for fifteen weeks. Food intake and body weight were monitored throughout the experimental period for calculation of food and energy intakes, weight gain, feed (FE) and energy efficiencies (EE). Feces were collected in last 72 hours of the experiment. Tail systolic blood pressure (SBP) and heart rate (HR) were measured at the beginning and in the last week of the experiment. On the last day, the animals were euthanized; the abdominal and thoracic cavities were opened for sampling. It was determined: (a) The left tibia length; (b) the absolute and relative liver, pancreas and hearts weights and all the retroperitoneal and epididymal fat pads; (c) plasma concentrations of cholesterol (COL), high density lipoprotein (HDL), triglycerides (TG), glucose, insulin, HOMA-IR index and atherogenic index; (d) the liver and fecal concentrations of COL and TG; (e) fecal moisture and pH; (f) plasma, muscle (soleus), liver and heart total antioxidant capacity - Ferring Reducing Antioxidant Power (FRAP); (g) liver, muscle and heart levels of lipid peroxidation - Thiobarbituric acid reactive substances (TBARS); (h) liver and muscle activity of superoxide dismutase (SOD); (i) liver, muscle and heart activity of catalase (CAT). Duodenal tissue samples were collected for histomorphometric analyses. It was observed the intake of pequi pulp associated to RAE did not influence significantly animal?s growth (food and caloric intake, body weight, FE, EE, organ weights, tibia length), SBP and HR, plasma glucose and insulin, HOMA-IR and atherogenic indexes. However, this association reduced visceral fat pad weights. There were no differences among treatments for plasma COL, HDL and TG. However, the intake of pequi pulp associated to RAE led to lower hepatic deposition and increased fecal output of lipids, in addition to better preserve the intestinal villi height and to promote increased crypt depth. There were no significant effects regarding redox state of all variables, although CAT activity was increased in the liver of the animals fed pequi pulp plus RAE. The reduction of visceral fat and hepatic lipid deposition with increased excretion, the increased cell renewal without damaging the structure of the intestine, the increased endogenous antioxidant activity, and the absence of harmful effects on other variables, point out that the intake of pequi pulp associated to RAE is a possible strategy for reducing the risk of non-communicable diseases and for health maintenance.

O ?leo de pequi (Caryocar brasiliense) apresenta em sua composi??o predom?nio de ?cidos graxos monoinsaturados e carotenoides antioxidantes, os quais t?m sido tamb?m relacionados ? redu??o do risco para DCNT. Entretanto, ainda s?o escassos na literatura estudos que avaliem efeitos fisiol?gicos do ?leo de pequi dentro da perspectiva de alimento funcional, ou seja, associado ? dieta usual e h?bitos saud?veis de vida, dentre os quais se destaca o exerc?cio f?sico regular. Diante desse contexto, o objetivo deste estudo foi pesquisar a influ?ncia da ingest?o do ?leo de pequi associada ao exerc?cio f?sico aer?bio regular (EFAR), sobre vari?veis relacionadas ao crescimento, ao metabolismo e par?metros cardiovasculares de ratos, desde est?gios iniciais de vida (p?s-desmame) at? o in?cio da vida adulta (20 semanas de vida). O protocolo experimental consistiu de quatro grupos (n=8) de ratos Wistar machos: CS - animais que receberam ra??o; CT - receberam ra??o e EFAR; OS - receberam ra??o suplementada com ?leo de pequi (2,25/100g = +50% do conte?do lip?dico da ra??o) e OT - receberam ra??o suplementada com ?leo de pequi e EFAR. O EFAR foi realizado em piscina, em intensidades e cargas progressivas, e a dieta fornecida ad libitum durante 15 semanas. A ingest?o alimentar e o peso corporal foram monitorados durante o per?odo experimental para os c?lculos da ingest?o alimentar e cal?rica, do ganho de peso, do coeficiente de efici?ncia alimentar (CEA%) e do ?ndice de massa corporal (IMC). A press?o arterial sist?lica (PAS) e a frequ?ncia card?aca (FC) foram aferidas no in?cio e na ?ltima semana do experimento. No ?ltimo dia, os animais foram eutanasiados, as cavidades abdominais e tor?cicas foram abertas para coleta de amostras. Os cora??es foram retirados e o ?ndice de contratilidade (+dP/dt) e relaxamento (-dP/dt) card?aco foram analisados pela t?cnica de cora??o isolado. Foram determinados: (a) o comprimento da t?bia esquerda; (b) os pesos absolutos e relativos do f?gado, p?ncreas e cora??o e de toda a gordura das regi?es epididimal e retroperitoneal; (c) as concentra??es plasm?ticas de colesterol (COL), lipoprote?na de alta densidade (HDL), triglicer?deos (TG), glicose, insulina, o ?ndice HOMA e a raz?o COL/HDL; (d) as concentra??es hep?ticas de COL e TG. Observou-se que a associa??o do ?leo de pequi ao EFAR n?o influenciou de maneira significativa par?metros relacionados ao crescimento (ingest?o alimentar e cal?rica, peso corporal, CEA, peso de ?rg?os, comprimento da t?bia), a PAS e FC, a glicemia e a raz?o COL/HDL. No entanto, foi essencial para evitar o ac?mulo de gordura na regi?o visceral, a eleva??o nos n?veis de insulina plasm?tica e no ?ndice HOMA-IR provocados pela ingest?o isolada do ?leo de pequi. Por outro lado, a associa??o da ingest?o do ?leo de pequi ao EFAR melhorou a capacidade de contra??o e relaxamento card?acos. Assim, podemos inferir que a ingest?o do ?leo de pequi, quando associada ? pr?tica regular de exerc?cios aer?bios, pode favorecer, sobretudo, a fun??o card?aca sem exercer efeitos delet?rios no crescimento e em vari?veis relacionadas ao metabolismo lip?dico e glic?dico. / Disserta??o (Mestrado) ?

Pequi oil (Caryocar brasiliense) is high in monounsaturated fatty acids and antioxidant carotenoids, which have also been associated to reduced risk for NCDs. However, there is lacking of studies evaluating pequi oil physiological effects from the perspective of being a functional food, which means, associated to a usual diet and a healthy lifestyle, being the regular physical exercise a part of it. In this context, the aim of this study was to investigate the influence of pequi oil intake, associated to regular aerobic physical exercise (RAPE) on variables related to growth, metabolism and on cardiovascular parameters of rats, from early stages of life (post weaning) to early adulthood (20 weeks old). The experimental protocol consisted of four groups (n = 8) of male Wistar rats: CS - animals fed chow; CT - received chow and RAPE; OS - received chow added pequi oil (2.25 / 100g =+50% of the chow lipid content) and OT - received chow added pequi oil and RAPE. The RAPE was held in a pool at intensities and progressive loading, and the diets were fed ad libitum for 15 weeks. Food intake and body weight were monitored throughout the experimental period to determine food and caloric intake, weight gain, feed efficiency ratio (FER%) and body mass index (BMI). Systolic blood pressure (SBP) and heart rate (HR) were measured at baseline and in the last week of the experiment. On the last day, animals were euthanized and the abdominal and thoracic cavities were opened for sampling. Hearts were removed and the contractility (+dP/dt) and relaxation (-dP/dt) indexes were analyzed by the isolated heart technique. It were determined: (a) The left tibia length (b) the relative liver, pancreas and hearts weights and the retroperitoneal and epididimal fat pad weights; (c) plasma concentrations of cholesterol (COL), high density lipoprotein (HDL), triglycerides (TG), glucose, insulin, HOMA-IR index and COL/HDL ratio; (d) hepatic TG and COL levels. The association of pequi oil intake to RAPE did not influence significantly growth (food and caloric intake, body weight, FER%, organ weights, tibia length), SBP and HR, blood glucose and COL/HDL ratio. However, it prevented fat accumulation in the visceral region and plasma insulin and HOMA-IR increases caused by the pequi oil intake solely. Moreover, the pequi oil intake associated to RAPE improved the heart contraction and relaxation ability. Thus, we can infer that pequi oil intake, when associated to RAPE can improve mainly cardiac function without exerting deleterious effects on growth and on glucose and lipid metabolism.

Diversas estrat?gias t?m sido utilizadas com o intuito de acelerar a recupera??o p?s-exerc?cio. Embora a imers?o em ?gua seja uma estrat?gia comum entre os atletas, a sua efic?cia na acelera??o da recupera??o ainda n?o est? estabelecida, e os efeitos da temperatura da ?gua na imers?o sobre o desempenho n?o s?o claros. Sendo assim, este estudo avaliou os efeitos da recupera??o passiva por imers?o em ?gua, em diferentes temperaturas, sobre o desempenho ap?s uma sess?o de exerc?cio. Nove homens, jovens, fisicamente ativos, participaram de quatro sess?es experimentais randomizadas compostas por exerc?cio exc?ntrico (3 x 10 repeti??es a 100% de uma repeti??o m?xima) e 90 minutos de corrida em esteira rolante a 70% do pico de consumo de oxig?nio. Em seguida, os volunt?rios recuperaram durante 45 minutos, distribu?dos em 15 minutos de imers?o em ?gua a 15, 28 ou 38?C sentados e 30 minutos deitados em repouso a temperatura ambiente (20 ? 2? C). Na sess?o controle (CON), durante a recupera??o, os volunt?rios permaneceram sentados durante 15 minutos ? temperatura ambiente. Quatro horas ap?s o final do exerc?cio experimental, os volunt?rios foram submetidos ? corrida de intensidade autorregulada m?xima de 5 km seguido do teste de Wingate para avaliar o desempenho f?sico. A temperatura retal (Tret), a frequ?ncia card?aca (FC) e sua variabilidade (VFC) foram medidas ao longo de toda a sess?o. O consumo excessivo de oxig?nio p?s-exerc?cio (EPOC) foi medido durante a recupera??o. Os marcadores do dano muscular, creatina quinase (CK) e aspartato amino transferase (AST) e a contagem de leuc?citos totais foram medidas antes e ap?s o exerc?cio, ap?s imers?o, antes e ap?s o desempenho, e 24 horas ap?s o exerc?cio experimental. A velocidade m?dia na corrida de intensidade autorregulada m?xima de 5 km e a pot?ncia pico relativano teste de Wingate n?o foram diferentes entre as condi??es experimentais. A imers?o em ?gua a 15?C reduziu a Tret, a FC e os ?ndices de VFC a valores de repouso, ap?s a recupera??o. O EPOC foi maior na imers?o em ?gua a 15?C e a 28?C. Durante a corrida de intensidade autorregulada de 5 km e do teste Wingate, a Tret e a FC n?o foram diferentes entre as condi??es experimentais. A sess?o de exerc?cio experimental induziu dano muscular e leucocitose. Entretanto, n?o houve diferen?a nos n?veis s?ricos de CK, AST e no n?mero de leuc?citos totais entre as condi??es experimentais. A recupera??o por imers?o em ?gua,a diferentes temperaturas, n?o foi efetiva em modificar o desempenho f?sico 4 horas ap?s uma sess?o de exerc?cio prolongado. / Disserta??o (Mestrado) ?

Several strategies have been used in order to accelerate post-exercise recovery. Although water immersion is a common strategy among athletes, it effectiveness in accelerate the recovery is not yet established, and the effects of temperature water immersion on performance are not clear. Thus, this study evaluated the effects of passive recovery water immersion at different temperatures on performance following an exercise session.Nine physically active men (24 ? 6 years old, 72 ? 13 kg, 177 ? 7 cm, peak oxygen consumption (VO2peak) of 55 ? 4 mL?kg- 1?min-1), participated of four randomized experimental sessions. Each session consisted of eccentric knee flexion (3 x 10 repetitions of 100% from one maximum repetition) and 90 minutes of treadmill running at 70% of VO2peak, followed by 15 minutes of passive recovery by water immersion at 15?C, 28?C or 38?C and 30 minutes resting in supine position at room temperature (20 ? 2?C). In the control session, volunteers remained seated for 15 minutes at room temperature after exercise. After four hours of resting, in order to evaluate recovery strategies, the volunteers underwent a 5 km of maximal self-paced treadmill running followed by the Wingate test. Prior to experimental sessions, rested volunteers completed 5 km of maximal self-paced running and the Wingate test, which were used as reference performance values. Rectal temperature (Tret), heart rate (HR) and heart rate variability indexes (HRV indexes) were measured through the entire session. Excess post-exercise oxygen consumption (EPOC) was measured during recovery period. The markers of muscle damage, creatine kinase (CK) and aspartate aminotransferase (AST) and total leukocyte count were measured before and after exercise, after immersion, before and after performance tests, and 24 hours after the experimental exercise. Average speed during 5 km of maximal self-paced treadmill running and relative peak power during Wingate test were not different between experimental conditions. Water immersion at 15?C reduced Tret, HR and HRV indexes to baseline values after recovery. EPOC was higher in water immersion at 15?C and 28?C. During 5 km of maximal self-paced treadmill running and Wingate test, Tret and HR were not different between experimental conditions. The experimental exercise session induced muscle damage and leukocytosis. However, there was no difference in serum CK, AST and total leukocyte count between experimental conditions.The recovery by water immersion at different temperatures was not effective in modify the physical performance 4 hours after a session of prolonged exercise.

In order to achieve the general objective, the work was done systematically in three stages which consisted the specific objectives. The first stage was the implementation of geodetic reference infrastructure for carrying out the geodetic survey of the study area. This process included the implementation of RGLS (Northern Coast of the RN GPS Network), consisting of stations with geodetic coordinates and orthometric heights of precision; positioning of Benchmarks and evaluation of the gravimetric geoid available, for use in GPS altimetry of precision; and development of software for GPS altimetry of precision. The second stage was the development and improvement of methodologies for collection, processing, representation, integration and analysis of CoastLine (CL) and Digital Elevation Models (DEM) obtained by geodetic positioning techniques. As part of this stage have been made since, the choice of equipment and positioning methods to be used, depending on the required precision and structure implanted, and the definition of the LC indicator and of the geodesic references best suited, to coastal monitoring of precision. The third step was the seasonal geodesic monitoring of the study area. It was defined the execution times of the geodetic surveys by analyzing the pattern of sediment dynamics of the study area; the performing of surveys in order to calculate and locate areas and volumes of erosion and accretion (sandy and volumetric sedimentary balance) occurred on CL and on the beaches and islands surfaces throughout the year, and study of correlations between the measured variations (in area and volume) between each survey and the action of the coastal dynamic agents. The results allowed an integrated study of spatial and temporal interrelationships of the causes and consequences of intensive coastal processes operating in the area, especially to the measurement of variability of erosion, transport, balance and supply sedimentary over the annual cycle of construction and destruction of beaches. In the analysis of the results, it was possible to identify the causes and consequences of severe coastal erosion occurred on beaches exposed, to analyze the recovery of beaches and the accretion occurring in tidal inlets and estuaries. From the optics of seasonal variations in the CL, human interventions to erosion contention have been proposed with the aim of restoring the previous situation of the beaches in the process of erosion. / O objetivo geral desta Tese de Doutorado foi o monitoramento costeiro sazonal (em escala temporal trimestral) de ?reas costeiras e estuarinas de um trecho do Litoral Setentrional do Estado do Rio Grande do Norte, Brasil, sens?vel ambientalmente e de intensa eros?o sedimentar sob as atividades petrol?feras, para servir de base na implanta??o de projetos de conten??o da eros?o e na mitiga??o dos impactos causados pela din?mica costeira. Para atingir o objetivo geral, o trabalho foi desenvolvido de maneira sistem?tica em tr?s etapas, as quais consistiram os objetivos espec?ficos. A primeira etapa foi da implanta??o da infraestrutura geod?sica de refer?ncia para a realiza??o dos levantamentos geod?sicos da ?rea de estudo. Compreendeu a implanta??o da Rede GPS do Litoral Setentrional do RN (RGLS), constitu?da de esta??es com coordenadas geod?sicas e altitudes ortom?tricas de precis?o; posicionamento de Refer?ncias de N?vel (RN) e avalia??o do modelo geoidal gravim?trico dispon?vel, para serem utilizados na altimetria por GPS de precis?o; e desenvolvimento de aplicativos para a altimetria por GPS de precis?o. A segunda etapa foi do desenvolvimento e aperfei?oamento de metodologias para o levantamento, processamento, representa??o, integra??o e an?lises de Linhas de Costa (LC) e Modelos Digitais de Eleva??o (MDE) obtidos por t?cnicas geod?sicas de posicionamento.

A terceira etapa foi do monitoramento geod?sico sazonal da ?rea de estudo. Definiu as ?pocas de execu??o dos levantamentos geod?sicos, a partir da an?lise do padr?o de din?mica sedimentar da ?rea de estudo; execu??o dos levantamentos, com os objetivos de calcular e localizar ?reas e volumes de eros?o e acres??o (balan?os sedimentares areal e volum?trico) ocorridas nas LC e nas superf?cies das praias e ilhas ao longo do ano, e estudo das correla??es entre as varia??es mensuradas (em ?rea e volume) entre os levantamentos e a atua??o dos agentes din?micos costeiros. Os resultados permitiram um estudo integrado das rela??es espaciais e temporais das causas e consequ?ncias dos intensos processos costeiros atuantes na ?rea, especialmente com a mensura??o da variabilidade da eros?o, transporte, balan?o e suprimento sedimentares ao longo do ciclo anual de constru??o e destrui??o das praias. Nas an?lises dos resultados, foi poss?vel identificar as causas e consequ?ncias da intensa eros?o costeira nas praias expostas, analisar a recupera??o sedimentar das praias e a acres??o nos canais de mar? e nos estu?rios. A partir da ?tica das varia??es sazonais das linhas de costa, interven??es antr?picas de conten??o de eros?o foram propostas com o objetivo de recuperar a situa??o anterior das praias em processo de eros?o.

The purpose of this investigation was to analyze the relationship between social demographics and health aspects of the functional condition in elderly women of low income of the Brazilian northeast. This crosssectional study involved a representative sample of 222 women with an average age of 70 years (? 7.1), belonging to coexisting groups and that were resident in the urban area of the municipal district of Jequi? /Bahia. In order to achieve this objective, a battery of physical tests of functional aptitude was carried out previously tested in pilot study, anthropometric measurements collected with a comparison of the measures referred to the reported weight and height as well as the application of an interview with questions containing subjects related to social demographic variables, clinical conditions and health, physical conditions and behaviors. Descriptive statistics Proceedings (frequency, average, standard deviation and percent distribution) were used for statistic analysis, and the calculation of the respective odds ratio by binary logistics regression, for the analysis of factors hierarchically grouped; p<0.05. The prevalence of 56% (n=122) of women considered with moderated or serious type of functional limitations was found, In which from multi-varied hierarchical analysis, significant association was verified with the age group over 80 years (p=0.02), conditions of widowhood (p=0.04), presence of arterial hypertension (p=0.001), and physical inactivity during leisure time (p=0.03). On the other hand for functional incapacities the prevalence was of 46.8% (n=104) being associated to the increase of the age (p=0.01), hospitalization (p=0.02), absence of physical activities along their lives (p=0.001) and the occurrence of alterations in the cognitive function (p=0.001). The normative table for the parameters of physical fitness generated conducive to health professionals in the diagnosis of health conditions and the prescription of physical exercises. The identified characteristics that are associated with the functional limitations / functional incapacities suggest a complex causal net in the determination of the functional condition in elderly women. However, actions addressed to the incentive of the practice of physical activities in the leisure time and the preservation of the cognitive function can contribute to a life with more quality for these people. This research was multidisciplinary approach to involve elements of psychology, nutrition and Physical Education in the elucidation of the object of study related to the functional condition of elderly women / A identifica??o de fatores que interferem no decl?nio da condi??o funcional ? ?til no planejamento de a??es direcionadas as melhorias nas condi??es de vida das pessoas idosas. O prop?sito dessa investiga??o foi o de analisar a rela??o dos aspectos s?cio-demogr?ficos e referentes a sa?de com a condi??o funcional em mulheres idosas de baixa renda do nordeste brasileiro. Este estudo teve um delineamento transversal, tendo uma amostra representativa de 222 mulheres, com m?dia de 70 anos (? 7,2) pertencentes a grupos de conviv?ncia e que eram residentes na zona urbana do munic?pio de Jequi?, Bahia. Para tanto foi conduzida uma bateria de testes de desempenho f?sico para avalia??o da aptid?o funcional previamente testada em estudo piloto, coletadas medidas antropom?tricas com a compara??o de medidas referidas com as reportadas para o peso e estatura, al?m da aplica??o de uma entrevista contendo quest?es relativas ?s vari?veis s?cio-demogr?ficas, condi??es cl?nicas, sa?de percebida, condi??es f?sicas e comportamentais. Para an?lise estat?stica foram utilizados procedimentos da estat?stica descritiva (freq??ncia, m?dia, desvio padr?o e distribui??o percent?lica) e o c?lculo da respectiva raz?o de chances mediante regress?o log?stica bin?ria, para an?lise de fatores hierarquicamente agrupados; p<0,05. Encontrou-se uma preval?ncia de 56% (n=122) de mulheres consideradas com limita??es funcionais do tipo moderada ou grave, nos quais a partir de an?lise multivariada hierarquizada, verificaram-se associa??o significativa com a faixa et?ria superior a 80 anos (p=0,02), condi??es de viuvez (p=0,04), presen?a de hipertens?o arterial (p=0,001), e inatividade f?sica no lazer (p=0,03). J? para as incapacidades funcionais a preval?ncia foi de 46,8% (n=104) sendo associada ao aumento da idade (p=0,01), hospitaliza??o (p=0,02), aus?ncia de pr?ticas de atividades f?sicas ao longo da vida (p=0,001) e a ocorr?ncia de altera??es na fun??o cognitiva (p=0,001). A tabela normativa para os par?metros de aptid?o f?sica gerada favorece aos profissionais de sa?de no diagn?stico das condi??es de sa?de e na prescri??o de exerc?cios f?sicos. As caracter?sticas identificadas que se associaram ?s limita??es funcionais/incapacidades funcionais sugerem uma complexa rede causal na determina??o da condi??o funcional em mulheres idosas. No entanto, a??es direcionadas ao incentivo da pr?tica de atividades f?sicas no lazer e a preserva??o da fun??o cognitiva podem contribuir para uma vida com mais qualidade a estas pessoas. Esta investiga??o teve a abordagem multidisciplinar ao envolver elementos da psicologia, nutri??o e da Educa??o F?sica na elucida??o do objeto de estudo relacionado ? condi??o funcional de mulheres idosas.

The sample was composed of 25 elderly sedentary women, aged between 60 and 75 years, allocated into two groups: an experimental group consisting of 14 women submitted to aerobic treatment and a control group (n=11). Carotid artery resistance assessment was conducted using Doppler ultrasound and functional autonomy by the following tests: 10m walk (10mW), rising from a sitting position (RSP), rising from a chair and moving about the house (RCMH), rising from the ventral decubitus position (RVDP) and putting on and removing a t-shirt (PRTS). Aerobic training consisted of walking 30 minutes a day, 3 times a week, for 3 months. To control the intensity of the walk, the index of perceived exertion was used, with standardized Borg scale values corresponding to 13-15 points, characterized as slightly tiring exercise with training heart rate (TRH) between 50% and 80% of heart rate reserve (HRR). Repeated measures ANOVA was used for statistical analysis. Compared to the control, the experimental group obtained a statistically significant decrease in right internal carotid resistance (p = 0.021) and a significant increase in the following tests: 10mW (p=0.000), RSP (p=0.035) and RCMH (p=0.016). These results suggest that engaging in aerobic exercises was effective in decreasing IRCRI and improving functional autonomy inelderly women / Este estudo teve como objetivo analisar os efeitos de um programa de exerc?cio f?sico aer?bico sobre o ?ndice de resist?ncia da art?ria car?tida interna direita (IRCID) e os n?veis de autonomia funcional de mulheres idosas. A amostra foi constitu?da por 25 idosas sedent?rias, com idade entre 60 e 75 anos, divididas em dois grupos: grupo experimental com 14 idosas submetidas ao treinamento aer?bico e grupo controle (n=11). A avalia??o da resist?ncia da art?ria car?tida foi realizada pelo m?todo de ultrasom Doppler e a autonomia funcional pelos testes: caminhar 10m (C10m), levantar da posi??o sentada (LPS), levantar-se da cadeira e locomover-se pela casa (LCLC), levantar-se da posi??o dec?bito ventral (LPDV) e vestir e tirar a camisa (VTC). O treinamento aer?bico foi realizado na forma de caminhada, 30 minutos por dia, 3 vezes por semana, durante 3 meses. Para o controle da intensidade da caminhada foi utilizado o ?ndice de esfor?o percebido, com valores padronizados pela escala de Borg onde a intensidade deveria corresponder a uma faixa entre os valores 13 a 15 pontos, correspondente a uma situa??o org?nica derivada de um exerc?cio compreendido como ligeiramente cansativo e a frequ?ncia card?aca de treino (FCT) entre 50% a 80% da frequ?ncia card?aca de reserva. Para analise estat?stica foi utilizado a ANOVA de medidas repetidas. O grupo experimental quando comparados com o grupo controle obteve uma diminui??o estatisticamente significativa na resist?ncia da art?ria car?tida interna direita (p=0,021), e um aumento significativo nos testes: C10m (p=0,000), LPS (p=0,035) e no LCLC (p=0,016). Estes resultados sugerem que a pr?tica de exerc?cios f?sicos aer?bicos foi eficaz em diminuir o IRCID e melhorar os n?veis de autonomia funcional em mulheres idosa

One of the important points of analysis is the realization of the fundamental right of access to water, a right that is implicit in the Constitution of 1988, being prevented from having their achievement considering the lack of definition of the ownership of the service. Knowing discussed the essential public service, in all its stages, it will realize it is a complex activity that depends for its operation, joint activities of federal entities and the society.

For this study, we use data from the ESO public archive: (i) high resolution spectra (R 47000) from the UVES spectrograph on the VLT/UT2-ESO (for 7 stars, covering the wavelength range 3450-4515 ? and 5500-9400 ?) and (ii) high resolution spectra from HARPS spectrograph on the La Silla-ESO 3.60 m telescope (for 9 stars, covering the wavelength range 4200-6865 ?). Our spectral analysis is based on MARCS models of atmosphere and Turbospectrum spectroscopic tools. On the base of the computed parameters, the referred abundances appears to follow the same behavior of the solar curve abundances. Further, one observes a signifficant correlation between the abundance ratio [m/Fe] and condensation temperature (Tc) of refractory elements (Tc > 900 K). The behavior of the projected rotational velocity (v sin i) versus the computed abundances [m/Fe] is also analyzed, presenting no clear trends. This study oers additional constraints to trace the evolutive history of solar-like stars with planets, including the search for chemical dierences between stars with and without transit planets and anomalies in the studied abundances / No presente estudo, n?s determinamos os par?metros atmosf?ricos (Teff , log g, vmic e [Fe/H]) e as abund?ncias qu?micas de 16 ?ons (Fe I, Fe II, O I, Si I, Na I, Mg I, Al I, Ca I, Ti I, Co I, Ni I, Rb I, Zr I, Ba II, La II e Cr I) para 16 estrelas solares, com massas entre 0:8 e 1:2 M , aproximadamente, incluindo 10 estrelas com planetas detectados pelo telesc?pio espacial CoRoT. Para este estudo, foram usados dados do arquivo p?blico do ESO: (i) espectros de alta resolu??o (R 47000) do espectr?grafo UVES localizado no VLT/UT2- ESO (para 7 estrelas, cobrindo o dom?nio espectral de 3450-4515 ? e 5500-9400 ?) e (ii) espectros de alta resolu??o obtidos com o espectr?grafo HARPS localizado no telesc?pio de 3,60 m, em La Silla-ESO (para 9 estrelas, cobrindo a faixa de 4200-6865 ?). Nossa an?lise espectral ? baseada nos modelos de atmosfera MARCS e nas ferramentas espectrosc?picas do Turbospectrum. Com base nos par?metros obtidos, as abund?ncias referidas parecem seguir tend?ncia semelhante ? curva de abund?ncias solares. Adicionalmente, observa-se uma correla??o signi cativa entre a abund?ncia relativa [m/H] e a temperatura de condensa??o (Tc) dos elementos refrat?rios (Tc > 900 K). O comportamento da velocidade rotacional projetada (v sin i) em fun??o das abund?ncias obtidas tamb?m ? analisada, n?o apresentando correla??es claras.

Definiu-se como ?rea de estudo o bairro M?e Luiza, em Natal, capital do Estado do Rio Grande do Norte. O local foi escolhido por historicamente apresentar diversas condi??es de vulnerabilidade e exposi??o ao risco de desastres. Ap?s caracteriza??o socioambiental do local, foram elaborados dois ?ndices: Vulnerabilidade Social (IVS), com base em 17 vari?veis dispostas em question?rio aplicado ao longo do n?cleo populacional do bairro, sobre malha regular (amostragem sistem?tica), classificado em 5 n?veis de VS a partir de m?dia ponderada; e o ?ndice de Exposi??o aos Movimentos de Massa (IEMM), que teve como base 16 vari?veis que caracterizam condi??es de exposi??o a movimentos de massa no bairro, em n?veis classificados a partir de m?dia ponderada de 1 a 5. A rela??o entre estes dois resultados, especializados em mapa do bairro, produziu o ?ndice de Vulnerabilidade Socioambiental (IVSA) de M?e Luiza, classificado tamb?m em 5 n?veis, a partir de l?gica Boleana de correla??o para sobreposi??o cartogr?fica, com uso de software computacional ArcGIS v.9.3, sendo nomeadas como: Muito Baixa; Baixa; M?dia; Alta; e Muito Alta Vulnerabilidade Socioambiental no bairro. O estudo se baseia em metodologia proposta por Guerra et. al (2009) para o IEMM e Almeida (2010) para o IVS, que foram modificadas e adaptadas para a realidade local, produzindo uma in?dita metodologia aplicada nesta ?rea. Concluiu-se que o bairro tem maior parte de sua ?rea com Alta e Muito Alta Vulnerabilidade socioambiental a desastres, sendo definidas sete (7) ?reas cr?ticas, com Muito Alto IVSA, e perigos associados a movimentos de massa ou alagamento. Ao final elencou-se os principais problemas socioambientais encontrados, como elementos geradores para a proposi??o de medidas mitigadoras e/ou interven??es propostas, referentes a fatores de vulnerabilidade de ordem estruturais: como baixo padr?o construtivo das resid?ncias; drenagem urbana deficiente; im?veis abandonas em via de desabamento; infraestrutura dos acessos e conten??o de talude. E sociais: como falta de educa??o sobre risco socioambiental; renda e escolaridade dos moradores; presen?a de pessoas com dificuldade de locomo??o e/ou portadores de necessidades especiais. Esta realidade evidencia a necessidade de a??es urgentes aplicadas na resolu??o e/ou diminui??o dos problemas apontados, o que ? pauta ao final deste trabalho. / This work has as object the elaboration of social environmental indicator of disaster risk that are present in precarious areas of human occupation, related to intense environmental dynamic from the perspective of the studies about the subject in Geography. The District of M?e Luiza in Natal, capital city of Rio Grande do Norte, was defined as the study area. The place was chosen because it presents ?historically- several vulnerability conditions and exposure to disaster risk. After a local social environmental description, two indexes were elaborated: the Social Vulnerability Index (SVI or IVS in Portuguese), based on 17 (seventeen) variables arranged on a questionnaire addressed to the population nucleus of the district, on regular grid (systematic sampling), classified into 5 (five) levels of SV from the weighted average; and the Physical and Natural Exposure to the Mass Movements Index (EMMI or IEMM in Portuguese) which had 16 (sixteen) variables that feature conditions of exposure to the mass movements in the district with classified levels from the weighted average of 1 (one) to 5 (five). The relationship between these two results, specialized in the district map, produced the Social Environmental Vulnerability Index (SEVI or IVSA in Portuguese) of M?e Luiza, also classified into 5 (five) levels, following the Boolean logic correlation for cartographic overlay with use of computer software ArcGIS v.9.3, being named as: Very Low; low; average; high; and Very High Environmental Vulnerability in District. The study is based on the methodology proposed by Guerra et al (2009) for EMMI and by Almeida (2010) for SVI. They were modified and adapted according to the local reality, producing a new methodology in this study area. It was concluded that the neighborhood has most of its area with High and Very High Socio-environmental vulnerability to disasters, defined seven (7) critical areas, with Very High IVSA, and hazards associated with mass movements or flooding. In the end, the main issues that were found, such as generating elements for proposing mitigation measures and/or the proposed interventions were enumerated, related to structural order of vulnerability factors: how low constructive pattern of households; poor urban drainage; Real Estate forsaken in landslide routes; infrastructure ready access roads and slope containment. And social: as a lack of education about environmental risk; income and education of residents; presence of persons with limited mobility and/or those with special needs. This reality highlights the need for urgent action applied to the resolution and/or reduction of these problems, which is focusing the end of this work.

Diante disto, foram estudadas as propriedades f?sico-qu?micas, entre estas propriedades verificaram-se o comportamento reol?gico e a tens?o superficial dos pol?meros, variando a concentra??o e a temperatura. Ap?s a obten??o da concentra??o de overlep, foi analisada a tens?o interfacial da solu??o de petr?leo/poliacrilamidas e, estas em presen?a de tensoativo e EDTA. Tamb?m, observou-se a permeabilidade destas solu??es, modificando a concentra??o. Com isso, o objetivo desta caracteriza??o foi observar a viabilidade destas solu??es nos processos de deslocamento de petr?leo em meio poroso. Os resultados obtidos mostraram que o aumento da ionicidade das poliacrilamidas promove um aumento da viscosidade no meio. No caso da temperatura seu aumento reduz a viscosidade para as poliacrilamidas de baixa ionicidade, a aumenta a viscosidade das poliacrilamidadas de alta ionicidade. Quanto a permeabilidade, verificou-se que os pol?meros ani?nicos apresentaram press?es mais elevadas em compara??o aos pol?meros de baixa ionicidade, e acredita-se que esse comportamento esteja relacionado ?s viscosidades destes pol?meros, que s?o mais altas. Na tens?o superficial observou-se a regi?o da concentra??o de overlep de cada pol?mero, consequentemente foi observado que as cargas i?nicas n?o influenciaram consideravelmente na redu??o das tens?es interfaciais entre o ?leo e as poliacrilamidas e constataram-se redu??es das IFT de todas as solu??es estudadas quando comparada ao caso ?gua/petr?leo. Tal resultado ? um bom ind?cio para seu uso no processo de recupera??o avan?ada de petr?leo. Finalmente, ao injetar as solu??es estudadas no meio poroso, verificou-se que as solu??es de pol?meros com maior ionicidade em presen?a de tensoativo e EDTA promoveram uma sinergia na recupera??o avan?ada de petr?leo, quando comparadas ?s solu??es contendo apenas pol?meros. / Enhanced oil recovery has been the focus of countless research projects aiming for the improvement of the in place oil recovery from the reservoirs, especially because mature fields and/or fields containing heavy oil require further assistance to ensure oil flow and consequent production. Having that in mind, physical and chemical properties such as the rheological behaviour and the superficial tension of polymers, for different concentrations and temperatures, were studied. After obtaining the polymers critical aggregation concentration (c.a.c.), the interfacial tension (IFT) between the polyacrylamide/oil solutions was evaluated, as well as for the solutions containing surfactant (SB) and EDTA. The permeability and the application of those solutions in enhanced oil recovery of those solutions was also observed using the Botucatu arenite. The results obtained demonstrated that the increase in the polymers ionicity promotes an increase in the solution viscosity. An increase in temperature reduced the viscosity for the low ionicity polyacrylamides, but caused an increase in the viscosity for some of the high ionicity ones. Concerning permeability, the anionic polymers presented higher injection pressure values when compared to the lower ionicity ones, and that behaviour is believed to be related to the viscosities of those polymers, which are higher. Regarding superficial tension, the c.a.c. region for each polymer was observed, and the conclusion was that the ionic charges had little or no influence in the reduction of interfacial tensions between the oil and the polymers, while the decrease in IFT for all solutions was observed when compared to the system formed by water and oil. The aforementioned results are a good indicator that the polymers studied are suitable for the enhanced oil recovery process. By injecting the solutions into the porous media, it was observed that the solutions formed by SB associated to EDTA improved the flow inside the porous media. The results indicated that the enhanced oil recovery using the polymer/ surfactant/ EDTA solutions reached a recovery factor of 18 % of the original oil. In addition, it could be observed that polymers presenting the higher ionicity, associated to surfactant and EDTA, promoted a synergy in the enhanced oil recovery when compared to the solutions containing only polymers.
