The aesthetic universe and the evolution of artists under discussion are investigated through the processes of polyphony, territorialization, hybridization, performance, among other postulates - categories that constitute important bases for the construction of this work. Another relevant approach in this study is the relentless pursuit of reviewing the processes of invention and institution of territorial identity markers from the Northeast region through the interrelation between universal and local in the compositions of the three artists. Luiz Gonzaga acquired projection from the reinvention of the baião, but the accordionist from Araripe also appropriated himself from other musical rhythms, which exercised discursive and decisive functions for the institutionalization of the Northeast and the Northeastern people. Thus, the gonzaguean sonority had the ability to express a feeling of nordestinity, which reverberated and found resonance in their listeners/receivers. This proposal also seeks to understand how artists Gilberto Gil and Torquato Neto - members of the Tropicalia movement - appropriated themselves from the gonzaguean musical universe and of the genres regarded as coming from the Northeast, as well as other soundscapes. It is understood that in the songs from these composers there is a visible dialogue with the modus operandi of Luiz Gonzaga, when it comes to rhythms, performance, melodic elements, textual, as well as signs that refer to the acoustic culture of the northeastern hinterland. It aims, accordingly, at investigating, in the relation of the history with the music, the dialogism and polyphony and hybridization processes in the songs of such composers / Esta pesquisa busca discorrer e analisar a produção musical, o dialogismo e as inter-relações entre o compositor Luiz Gonzaga (1912-1989) e os artistas Gilberto Gil (1942) e Torquato Neto (1944-1972). O universo estético e a trajetória dos artistas em discussão são investigadas por meio dos processos de polifonia, territorialização, hibridação, performance, entre outros postulados categorias que constituem bases importantes para a construção deste trabalho. Outra abordagem pertinente neste estudo consiste na procura incessante por verificar os processos de invenção e instituição de marcadores identitários territoriais da região Nordeste pela inter-relação entre universal e local nas composições dos três artistas. Luiz Gonzaga ganhou projeção a partir da reinvenção do baião, mas também o sanfoneiro do Araripe se apropriou de outros ritmos musicais, os quais exerceram funções discursivas e determinantes para a institucionalização de Nordeste e de nordestino. Desse modo, a sonoridade gonzagueana teve a capacidade de expressar um sentimento de nordestinidade, que reverberou e encontrou ressonância em seus ouvintes/receptores. Nessa proposta, procura-se também compreender de que modo os artistas Gilberto Gil e Torquato Neto integrantes do movimento tropicalista apropriaram-se do universo musical gonzagueano e dos gêneros tidos como oriundos do Nordeste, bem como de outras paisagens sonoras. Compreende-se que nas canções desses compositores há um diálogo visível com o modus operandi de Luiz Gonzaga, no que se refere a ritmos, performance, elementos melódicos, textuais, além de signos que remetem à cultura acústica do sertão nordestino. Trata-se, nesse sentido, de averiguar, na relação da história com a música, o dialogismo e os processos de polifonia e hibridização nas canções dos referidos compositores

Ovine placental lactogen (oPL) is postulated to be involved in the repartitioning of maternal nutrients during pregnancy, through its effect on insulin metabolism. Ovine pancreatic insulin responses to exogenous glucose are depressed during pregnancy and this depression becomes more pronounced as gestation advances. In addition, under the hormonal environment of rising oPL and growth hormone (oGH) concentrations, maternal whole body glucose irreversible loss (GIL) increases. The percentage of GIL accounted for by uterine glucose uptake also increases with advancing gestation and increasing litter size. Regression analysis of oPL concentration with glucose uterine uptake as a percentage of GIL, accounts for 39% of variation. Maternal oPL concentrations which increase with gestational age, were significantly greater in multiple bearing ewes and ewes subjected to reduced metabolisable energy (ME) intakes. It is postulated that through actions on pancreatic sensitivity, oPL plays a major role as a homeorhetic control during pregnancy. Elevated oPL concentrations were strongly associated with continually depressed pancreatic insulin secretory ability. The reduction in pancreatic sensitivity to glucose was not as a result of elevation in GH or non-esterified fatty acid (NEFA) concentrations. Muscle insulin receptor number and affinity were found to increase with increasing litter size, suggesting that pregnancy associated insulin resistance occurs predominantly in adipose tissue. During ovine pregnancy there is a specific stimulation of maternal gluconeogenesis. As gestation advances, an increasingly greater proportion of this glucose is partitioned to the gravid uterus. The development of insulin resistance, together with the suppression of pancreatic activity, ensures the preferential uptake of glucose by non-insulin dependent tissues over insulin dependent tissues. These activities favour uterine glucose uptake, decrease adipose glucose uptake, and also promote adipose mobilisation and hepatic gluconeogenesis, so as to meet the increasing energy requirement of pregnancy. It is postulated that through these effects on insulin secretion and associated adipose tissue mobilisation factors, oPL plays a major role in homeorhesis during pregnancy. / Doctor of Philosophy (PhD)

(Our Exercise) website. This web application consists in one of the Tutorial Education Program Projects, PET-UFVJM/Mucuri Campus, located in Te?filo Otoni city, Minas Gerais state and it has as its objective the open share of teaching exercises of several knowledge areas. At the request of its creators, new functionalities were demanded to ?Nosso Exerc?cio? (Our Exercise), however, there were not clear goals for this project nor a work plan to be followed, the requirements were not formalised and the available team was not mature enough on the tecnologies applied. Considering the challenge faced on the generation of a good quality software and the time limit available for taking this research, the use of a software engineering was proposed aiming to get bigger quality control of the final Product to be developed. The agile method Scrum was the one chosen to manage the developing activities to this software. So, the general goal of this research consisted in searching for an answer to the following question-problem: Which benefits and/or difficulties can be obtained through the apllication of Scrum Framework on the evolution of the development of ?Nosso Exerc?cio? open plataforma? According to the model suggested by Coughlan and Coghlan (2002), the research-action method was used to describe a dinamic conducted during this work. The Scrum implantation on ?Nosso Exerc?cio? occurred in two stages, the first one, aimed to do a training about Scrum and the technological tools used in the development of ?Nosso Exerc?cio?. The second one, dealt with the development of functionalities to this website. The analyses of the results showed many benefits gotten with the implatation of Scrum in this project, like focus and commitment of ?Time? during its work, the attendance to the costumer?s real needs (Product Owner), the framework flexibility in adjusting to environment and work conditions of each ?Time? created, the continuous learning of the software and of the process resulting of the discussions taken on planning, reviewing and retrospecto meetings. The critical work point was about the immaturity with the technologies used for the website development. The learned lessons with this research indicate that it?s possible to get benefits with the implantation of Scrum Framework which overcome the difficulties, as long as the needed analysis of the enviroment where it was adopted be done.

According to Acácio Gil Borsoi, the house is, primarily, a program that made the architectural experimentation possible for him; it plays an essential role in his career, so much so that it is the architect s most recurrent program. From the observation of eight selected examples in Paraiba, it is expected that through the drawings based on analytical parameters specific and recurring aspects of the analyzed projects are revealed. This study aims to identify the architectural features in the set of singlefamily residential buildings designed by Acácio Gil Borsoi s in Paraiba, and compare them with general characteristics attributed to his projects by two of the most relevant pieces of work about him. / A pesquisa pretende iniciar um processo aprofundado de análise acerca da arquitetura residencial unifamiliar produzida pelo arquiteto carioca Acácio Gil Borsoi no Estado da Paraíba, com ênfase no período entre 1953 e 1979, que demarca o período de construção das casas selecionadas em solo paraibano. A casa, para Acácio Gil Borsoi, é, sobretudo, um programa que lhe permitiu experimentação arquitetônica, e possui um papel vital na sua carreira tanto que é o mais praticado pelo arquiteto. A partir da reflexão sobre oito exemplares paraibanos selecionados, espera-se, por meio dos desenhos baseados nos parâmetros analíticos, revelar aspectos recorrentes e particulares dos projetos estudados. O trabalho tem como objetivo identificar as características arquitetônicas do conjunto da obra residencial unifamiliar de Acácio Gil Borsoi na Paraíba e compará-las com as características mais genéricas atribuídas à sua obra por dois dos trabalhos mais relevantes sobre o autor.

Geometry, interconectivity and density of the brittle features developed during basin evolution could change the permo-porous character of the rocks involved in generation, migration and entrapment of fluid flow. Once the structural characterization of the reservois using only sub-surface data is not an easy task, many studies are focused in analogous outcrops trying to understand the main processes by which brittle tectonic is archieved. In the Santana do Acara? region (Cear? state, NE Brazil) a pack of conglomeratic sandstone (here named CAC) has its geometry controlled mainly by NE trending faults, interpreted as related to reactivation of a precambrian Sobral Pedro II Lineament (LSP-II). Geological mapping of the CAC showed a major NE-SW trending synform developed before its complete lithification during a dextral transpression. This region was then selected to be studied in details in order of constrain the cretaceous deformation and so help the understanding the deformation of the basins along the brazilian equatorial margin. In order to characterize the brittle deformation in different scales, I study some attributes of the fractures and faults such as orientation, density, kinematic, opening, etc., through scanlines in satellite images, outcrops and thin sections. The study of the satellite images showed three main directions of the macrostructures, N-S, NE-SW and E-W. Two of theses features (N-S and E-W) are in aggreement with previous geophysical data. A bimodal pattern of the lineaments in the CAC?s basement rocks has been evidenciated by the NE and NW sets of structures obtained in the meso and microscale data. Besides the main dextral transpression two others later events, developed when the sediments were complety lithified, were recognized in the area. The interplay among theses events is responsible for the compartimentation of the CAC in several blocks along within some structural elements display diferents orientations. Based on the variation in the S0 orientation, the CAC can be subdivided in several domains. Dispite of the variations in orientations of the fractures/faults in the diferents domains, theses features, in the meso and microscopic scale, are concentrated in two sets (based on their trend) in all domains which show similar orientation of the S0 surface. Thus the S0 orientation was used to group the domains in three major sets: i) The first one is that where S0 is E-W oriented: the fractures are oriented mainly NE with the development of a secondary NW trending; ii) S0 trending NE: the fractures are concentrated mainly along the trend NW with a secondary concentration along the NE trend; iii) The third set, where S0 is NS the main fractures are NE and the secondary concentration is NW. Another analized parameter was the fault/fracture length. This attribute was studied in diferent scales trying to detect the upscale relationship. A terrain digital model (TDM) was built with the brittlel elements supperposed. This model enhanced a 3D visualization of the area as well as the spatial distribution of the fault/fractures. Finally, I believe that a better undertanding of the brittle tectonic affecting both CAC and its nearby basement will help the future interpretations of the tectonic envolved in the development of the sedimentary basins of the brazilian equatorial margin and their oil reservoirs and prospects, as for instance the Xar?u field in the Cear? basin, which subsurface data could be correlated with the surface ones / Grande parte dos prospectos e reservat?rios de petr?leo tem o seu arcabou?o estrutural como um fator de grande import?ncia. A geometria, interconectividade e densidade dos elementos da tect?nica fr?gil (falhas, fraturas, etc.), t?m grande influ?ncia no car?ter permo-poroso do meio e, por conseguinte, no fluxo de fluidos. Tendo em vista as dificuldades encontradas para a caracteriza??o da deforma??o fr?gil, unicamente com dados de subsuperf?cie, v?rios estudos est?o sendo direcionados ao detalhamento das por??es emersas das bacias e de seus substratos, em busca de an?logos da deforma??o. Na Regi?o de Santana do Acara? aflora um corpo aren?tico conglomer?tico (CAC) cuja geometria ? controlada por falhas, principalmente de trend NE, interpretadas como decorrentes da reativa??o do Lineamento Sobral Pedro II (LSP-II). A fim de caracterizar a deforma??o fr?gil em diferentes escalas, estudou-se os atributos do fraturamento tais como: orienta??o, densidade, cinem?tica, abertura, etc., atrav?s de scanlines em imagens de sat?lite, afloramentos e se??es delgadas. O estudo das imagens de sat?lite mostrou que as macroestruturas da ?rea apresentam tr?s dire??es preferenciais sendo elas N-S, NE-SW e E-W. As dire??es N-S e E-W s?o compat?veis com movimento de blocos observados por estudos gravim?tricos. O estudo do CAC mostrou que ele apresenta uma estrutura sinformal alongada na dire??o NE-SW, fruto de uma tect?nica transpressional dextral desenvolvida enquanto o corpo ainda n?o estava completamente litificado. Foi evidenciada a exist?ncia de duas outras fases de reativa??o, ocorridas quando o CAC j? se encontrava totalmente litificado. A tect?nica fr?gil compartimentou o CAC em blocos, cujo basculamento, gera varia??es na orienta??o de alguns de seus elementos (S0, por exemplo). Com base na varia??o da orienta??o de S0, o CAC pode ser subdividido em v?rios dom?nios. Do ponto de vista da orienta??o do fraturamento/falhamento os estudos na meso e microescala mostraram que as rochas do embasamento do CAC possuem um padr?o de lineamentos basicamente bimodal (NE e NW), enquanto no CAC observou-se que, embora haja uma distribui??o do fraturamento em varias dire??es, em todos os dom?nios, a concentra??o ao longo de dois trends espec?ficos nos dom?nios que apresentam as mesmas orienta??es de S0 ? marcante, caracter?stica e distinta. Os diversos dom?nios s?o agrupados em tr?s conjuntos, onde o conjunto que apresenta S0 praticamente NW mostra um fraturamento principal com trend NE e secund?rio NW, enquanto que o conjunto apresentando S0 com dire??o NE, mostra uma maior concentra??o dos lineamentos ao longo dos trend NW e secundariamente com trend NE. No conjunto de dom?nios com S0 praticamente N-S, o trend principal do fraturamento ? NE e o secund?rio NW. Outros atributos do fraturamento, tal como o seu comprimento, foi tamb?m analisado e comparado em diversas escalas buscando verificar se existia uma rela??o de upscale. O desenvolvimento de um modelo digital de terreno, com as estruturas fr?geis superpostas, propiciou uma vis?o tridimensional da regi?o estudada. O entendimento da deforma??o fr?gil que atingiu o corpo aren?tico-conglomer?tico (CAC) da regi?o de Santana do Acara? (CE) e seu substrato reveste-se de import?ncia pela presen?a de reservat?rios fraturados nas bacias da margem equatorial brasileira (Campo de Xareu na bacia do Cear?, por exemplo), cujos dados podem ser confrontados com os de superf?cie

Among the criteria to evaluate frailty, gait speed has been identified as the most reliable predictor of fragility, practical and low cost. Objective: This study assesses the discriminating capability of gait speed in determining the presence of fragility in the elderly community in northeast of Brazil. Method: We performed an observational analytic study with a transversal character with a sample of 391 community-living elders, aged 65 years or older, of both sexes, in the city of Santa Cruz-RN. Participants were interviewed using a multidimensional questionnaire to obtain sociodemographic information, physical-related and mental health-related information. The unintentional weight loss, muscle weakness, self-reported exhaustion, slow gait and low-physical activity were considered to evaluate the frailty syndrome. Gait velocity was measured as the time taken to walk the middle 4,6 meters of 8,6 meters (excluding 2 meters to warm-up phase and 2 meters to deceleration phase).We calculate the sensitivity and specificity of gait speed test in different cutoff points for the test run time, from which ROC curve was constructed as a measure of test predictive value to identify frail elders. The prevalence of frailty in Santa Cruz-RN was 17.1%. The gait speed test accuracy was 71%when speed is below 0,91m/s. Among women, the gait speed test accuracy was 80%(gait speed below 0.77m/s) and among men, the test accuracy was 86% (gait spend below 0,82%) (p<0,0001).Conclusion: our findings have clinical relevance when we consider that the detection of frailty presence by the gait speed test can be observed in elderly men and women by a simple, cheap and efficient exam / A velocidade da marcha vem sendo descrita como um indicador preditivo de importantes desfechos adversos em popula??es idosas. Entre os crit?rios para a avalia??o de fragilidade, a velocidade da marcha tem sido apontada como o preditor de fragilidade mais confi?vel, pr?tico e de baixo custo. Objetivo: este estudo avalia a capacidade de discrimina??o da velocidade da marcha na determina??o da presen?a de fragilidade em uma amostra populacional de idosos comunit?rios brasileiros. M?todo: Foi realizado um estudo observacional anal?tico de car?ter transversal com uma amostra populacional de 391 idosos comunit?rios com idade de 65 anos ou mais, de ambos os sexos, da cidade de Santa Cruz-RN. Foi utilizado um question?rio multidimensional contendo informa??es sociodemogr?gicas e relativas ? sa?de f?sica e mental. Para avalia??o da s?ndrome de fragilidade, foram considerados: a perda de peso n?o intencional, fraqueza muscular, auto-relato de exaust?o, lentid?o na marcha e baixo n?vel de atividades f?sicas. A velocidade da marcha foi avaliada a partir do desempenho ao andar uma dist?ncia de 8,6 metros livres, excluindo 2 metros para a acelera??o e 2 metros para a desacelera??o, sendo o tempo final cronometrado para os 4,6m. Foram calculadas a sensibilidade e a especificidade do teste de velocidade da marcha em diferentes pontos de corte do tempo de execu??o do teste, a partir dos quais foi constru?da a curva ROC como uma medida de valor preditivo do teste para identificar idosos fr?geis. Resultados: A preval?ncia da fragilidade no munic?pio de Santa Cruz\RN, foi de 17.1%. A acur?cia da velocidade da marcha ficou em 71% com um ponto de corte de 0,91m/s. Em rela??o ao sexo, as mulheres apresentaram uma acur?cia de 80% com um ponto de corte de 0,77m/s, e os homens uma acur?cia de 86% onde o ponto de corte ficou em 0,82m/s (p<0,0001). Conclus?o: Nossos achados possuem relev?ncia cl?nica ao consideramos que, a detec??o da presen?a de fragilidade atrav?s do teste de velocidade da marcha pode ser observada em homens e mulheres idosos atrav?s de um exame simples, barato e eficiente

The environmental, economic concerns and the technological evolution allowed the consolidation of wind energy as a viable alternative energy source. To produce this type of electricity generation is required the construction of wind farms, which are high complexity projects. This research aims to propose a hybrid management project model of planning and controlling to assist the construction of wind farms by helping the process of building this sort of constructions. The first part of research was a preliminary field investigation and literature study on project management, wind power and construction of wind farms. During the second phase, the case study was performed about the construction of a wind farm, that is considered a reference in civil construction to better understand its process and how the project management was used. With this information, the planning and controlling hybrid model for construction of wind farms was proposed. It aims the improvement of wind projects edification resulting in better financial, customer satisfaction and skill projects aspects.
