Caracterização de reservatórios fraturados através de dados de ondas qP em levantamentos VSP Walkaway

Esta dissertação apresenta um método para estimar a orientação de fratura de um meio partindo do pressuposto que este se comporta efetivamente como um meio transversalmente isotrópico (TI). Desta forma, a orientação de fratura é obtida a partir da estimativa do eixo de simetria de um meio TI. Esta estimativa é obtida a partir dos vetores de vagarosidade e polarização de ondas qP medidos em experimentos VSP Walkaway. O processo de inversão é baseado em equações linearizadas dos vetores de vagarosidade e polarização de ondas qP e os parâmetros fracamente anisotrópicos do meio. São apresentados testes numéricos, em que a sensibilidade a fatores como grau de anisotropia, geometria do levantamento, tipo de onda utilizado e nível de ruído são analisados. São também apresentados os resultados para um conjunto de dados reais.

A dinâmica dos recursos comuns em Unidades de Conservação e Assentamentos Rurais no Amazonas: uma abordagem fuzzy set

A teoria de Garret Hardin intitulada “A tragédia dos comuns” apresenta a privatização e o controle governamental como saída para evitar o esgotamento dos recursos naturais. Entretanto, outros autores demonstraram que os usuários dos recursos podem apresentar eficientes formas de manejo, aliando o uso pelo homem à conservação da natureza. Esta tese analisa o uso de recursos comuns em Unidades de Conservação e Assentamentos Rurais de Uso Sustentável, localizadas no interflúvio Purus-Madeira, região Sul do Estado do Amazonas. A pergunta que norteou a hipótese da pesquisa foi: Diante das especificidades amazônicas e das regras impostas pelas políticas ambientais e agrárias na região, quais condições apresentam-se como necessárias e suficientes ao bom desempenho no uso de recursos comuns? A análise foi realizada por meio da combinação de três métodos: o método comparativo Qualitative Comparative Analysis (QCA), o método de análise institucional Institutional Analysis and Development (IAD) Framework e a lógica fuzzy. Operacionalmente, foram consideradas como variáveis independentes (X) os aspectos socioeconômicos, produtivos, ambientais e institucionais, partindo-se do pressuposto de que os programas governamentais destinados às Unidades devem apresentar melhorias nestes indicadores, refletindo por sua vez no bom desempenho no uso de recursos comuns (variável dependente Y) a partir deste desenho institucional. Os resultados confirmaram as hipóteses levantadas, afirmando-se que o bom desempenho no uso de recursos comuns, preconizado pelos critérios da sustentabilidade, somente pode ser alcançado mediante a combinação de um desempenho também satisfatório nas variáveis socioeconômicas, produtivas, institucionais e ambientais, apresentando-se estas variáveis como individualmente necessárias e conjuntamente suficientes para ocorrência deste fenômeno.

Autonomia funcional de idosas praticantes de Pilates

O objetivo foi avaliar o efeito do método Pilates na autonomia funcional de idosas. Foram selecionadas 52 voluntárias, submetidas à avaliação geral e ao protocolo de avaliação da autonomia funcional do Grupo Latino-Americano de Desenvolvimento para Maturidade (GDLAM), que consiste em cinco testes (caminhada de 10 m, levantar-se da posição sentada, levantar-se da cadeira e locomover-se pela casa, levantar-se da posição de decúbito ventral e vestir e tirar uma camiseta); em seguida, foram divididas em dois grupos: grupo Pilates (GP, n=27; idade 66,9±5,3 anos) e grupo controle (GC, n=25; idade 65,2±3,9 anos). O GP foi submetido a uma série de dez exercícios de Pilates, por oito semanas, duas vezes por semana. Os dois grupos foram reavaliados após esse período. O nível de significância considerado foi de p?0,05. O GP obteve resultados significativamente melhores em todos os testes e no índice geral do GDLAM (p=0,035) após a intervenção. O GC obteve escore significativamente melhor (p=0,042) apenas no teste de caminhada de 10 m, tendo mantido sua classificação inicial de funcionalidade regular. Comparando-se os escores dos grupos após a intervenção, encontraram-se diferenças significativas em favor do GP, inclusive no índice GDLAM (p<0,05), tendo este passado da classificação de regular a bom. A prática do método Pilates gerou pois melhora significativa do desempenho funcional das idosas estudadas.

Composição florística e estrutura da comunidade vegetal em diferentes fitofisionomias do Pantanal de Poconé, Mato Grosso

The aim of this research was to analyze the composition and structure of the plant community in four phytophysiognomies at Pantanal Poconé-Mato Grosso, assuming that each sample group is a type of community, and there would be a corresponding group of species that characterize that community. We set up five plots of 50 × 50 m and subdivided each one into subplots of 10 × 10 m. In each subplot, individuals with CAP (circunference at breast height) > 10 cm were sampled. To check the structural and floristic similarity of the five vegetation types the unweighted averages grouping method was used - UPGMA, with Jaccard's coefficient and Bray-Curtis, respectively. DCA ordination of plots was used for inundation gradient analysis and TWINSPAN indicator species groups for the three strata. In the four areas 55 species belonging to 30 families were sampled. The UPMGA indicated floristic and structural differences between cambarazal, savanna types and campo de murundu and similarity between the semideciduous formations. The DCA separated the vegetation types according to the level of flooding and TWINSPAN indicated the existence of typical species for each vegetation type. In the Pantanal, some species may be restricted to certain types of vegetation, and these species can be used as indicators of the effect of flooding and possible changes in flood pulse dynamics in plant communities.

Peanut mechanized digging regarding to plant population and soil water level

The largest losses in mechanical harvesting of peanuts occur during the stage of digging, and its assessment is still incipient in Brazil. Therefore, the aim of this study was to evaluate the quantitative losses and the performance of the tractor-digger-inverter, according to soil water content and plant populations. The experiment was conducted in a completely randomized block design with a factorial scheme 2 x 3, in which the treatments consisted of two soil, water content (19.3 and 24.8%) and three populations of plants (86,111, 127,603 and 141,144 plants ha-1), with four replications. The quantitative digging losses and the set mechanized performance were evaluated. The largest amount of visible and total losses was found in the population of 141.144 plants ha-1 for the 19.3% soil water content. The harvested material flow and the tractor-digger-inverter performance were not influenced by soil water content and plant population. The water content in the pods was higher in 24.8% soil water content only for the population of 86,111 plants ha-1; the yield was higher in the populations of 141.144 and 127.603 plants ha-1, in the 19.3 e 24.8% soil water content, respectively.

Equilíbrio funcional em indivíduos com doença de Parkinson e sua relação com a qualidade de vida

Introduction: Parkinson’s Disease (PD) is characterized by a set of four motor symptoms: tremor, rigidity, bradykinesia and postural instability. These defi cits may predispose individuals to limitations resulting from falls and their secondary consequences. Objective: To evaluate the functional balance and quality of life (QoL) in individuals with PD and determine whether there is correlation between performance on tests of balance with the QoL. Method: The project was referred to the Ethics Committee in Research of Universidade Estadual Paulista “Julio de Mesquita Filho” Campus de Marília and was approved under protocol number 1806/09. Participated in this study with individuals diagnosed with PD between levels one and four in the Hoen and Yahr scale. The subjects were evaluated according to functional balance and QoL, respectively by the instruments: Functional Balance Scale Berg (EEFB), Time Up and Go test (TUG), and Parkinson’s Disease Questionnaire-39 (PDQ-39). To perform the statistical analysis used the GraphPad Prism 5. To perform the correlation analysis for the variables passed normality by the Shapiro-Wilk. Since the variables were non-parametric test was used Spearman. During the analysis the statistical signifi cance level was considered p ≤ 0, 05. Results: We studied 25 individuals aged between 54 and 85 years (71.20 ± 8.50), time of diagnosis between one and 39 years (6.54 ± 7.71) disease. Moderate correlation was found between the EEFB with QoL (r =- 0.6), and TUG with QoL (r = 0.6836). Among the aspects of QoL balance showed a higher correlation with the domains “mobility” (TUG r = 0, 6768; EEFB r = -0.6155) and “Activities of daily living” (TUG r = 0, 7357, and EEFB r = -0.6521). Conclusion: Patients with Parkinson’s disease show defi cits in balance and QoL. The balance disorders have a high correlation among themselves and show how aspects of QoL.

Correlação entre equilíbrio, assimetria de passos e descarga de peso em indivíduos hemiparéticos

Introduction: Hemiparesis is the most common sequels after Stroke. One of the side effects of the motor skills evident in hemiparesis is the tendency to remain in asymmetric posture, with lower distribution of weight on the side hemiparetic, which ends up leading to a deficit in balance. This set of changes can cause an asymmetrical type of gait, marked by difference between the lengths of the steps these individuals. Objective: The purpose of this study was to analyze the balance, the discharge of weight in the lower limbs and asymmetry of steps in hemiparetic individuals and sees if there is correlation between those variables. Method: A group of 12 hemiparetic individuals (55,33 ± 8,92 years), both sex, who suffered from strokes participated. All subjects performed the assessment of bilateral discharge of weight, the length of the steps and balance (Berg Balance Scale). The results for the difference in the discharge of weight of the lower limbs, asymmetry of the step and the performance on the test of balance were analyzed using the Sperman Correlation Coefficient with a significance level of 5% (p ≤ 0.05). Results: We found a significant correlation between balance and asymmetry of the steps (R = -0.72 and p = 0007), however, found no significant correlation between discharge of weight on each leg and the symmetry of the steps (R =- 0.07 and p = 0, 81) and between discharge of weight and balance (R =- 0.08 and p = 0.79) in these hemiparetic individuals. Conclusion: Can be conclude that hemiparetic individuals of these study show deficits in balance, difference in weight between the discharge of the lower limbs and asymmetry of step and correlation between the asymmetry of the step and balance.

A interferência do estado de humor na melhora dos componentes da capacidade funcional em idosos

Mood States are feelings auto regulation deliver to individual better quality of life and healthy aging. The declines of the aging process can be minimized with the regular practice of physical activity and systematized. The objective of this study was to evaluate the effects of a dance program in mood states, depressive symptoms and functional capacity in elderly participants of PROFIT. METHOD: The sample was composed of 20 elderly people. The Training Group was formed by 15 elders who participated in a protocol of dance with duration of 1 hour, three times per week, for 12 weeks and the Control Group, composed of 5 elderly, did not attend any program of physical activity. The participants were evaluated by the List of States of Mind Reduced and Illustrated, Geriatric Depression Scale and the battery of tests of AAHPERD. For the mood states was used non-parametric analysis, according to the technique of Binomial Analysis. To compare the components of functional capacity between the groups was used analysis of variance for repeated measures two-way ANOVA and the level of significance was set at 5 %. RESULTS: The functional components remained favorable, highlighting Agility (pre = 21.03 ± 1.64 sec./ post = 18.63 ± 2.26 sec.) And aerobic endurance (pre = 495.94 ± 46.48 sec. / post = 448.01 ± 12.27 sec.). In the comparison between positive and negative functional levels and mood states showed no relationship between these variables, dealing with different aspects and has influence one another. The state post-dancing sessions mood in GT were more positive even for elderly patients with depressive symptoms even unproven statistically, depressive symptoms were maintained or reduced mostly. CONCLUSION: The dance practice maintains the functionality of components; modifies mood states to positive levels and reduces or prevents the onset of depressive symptoms and complications in elderly

Very Intense Distinct Blue and Red Photoluminescence Emission in MgTiO 3 Thin Films Prepared by the Polymeric Precursor Method: An Experimental and Theoretical Approach

MgTiO3 (MTO) thin films were prepared by the polymeric precursor method with posterior spin-coating deposition. The films were deposited on Pt(111)/Ti/SiO2/Si(100) substrates and heat treated at 350 °C for 2 h and then heat treated at 400, 450, 500, 550, 600, 650 and 700 °C for 2 h. The degree of structural order−disorder, optical properties, and morphology of the MTO thin films were investigated by X-ray diffraction (XRD), micro-Raman spectroscopy (MR), ultraviolet− visible (UV−vis) absorption spectroscopy, photoluminescence (PL) measurements, and field-emission gun scanning electron microscopy (FEG-SEM) to investigate the morphology. XRD revealed that an increase in the annealing temperature resulted in a structural organization of MTO thin films. First-principles quantum mechanical calculations based on density functional theory (B3LYP level) were employed to study the electronic structure of ordered and disordered asymmetric models. The electronic properties were analyzed, and the relevance of the present theoretical and experimental results was discussed in the light of PL behavior. The presence of localized electronic levels and a charge gradient in the band gap due to a break in the symmetry are responsible for the PL in disordered MTO lattice.
