Ideologia e poder no agendamento do discurso polifônico da imprensa em relação à seca no nordeste

This dissertation work is an effort to understand how the ideology and the power interferes in the signification of the speeches immersed in the context of the printed media concerning the drought in the Northeast of Brazil, weather occurrence that punishes 23 million of Brazilians, with all sort of problems. It also has specific concern about the everyday usage of the language and with the routines of the information production, without losing of sight the role of History in the formation of the identity of individuals and people. The research work is also developed in an interdisciplinary environment, applying to the formed corpus five articles from Folha de São Paulo , collected from January to July of 2005, the French Analysis method of the Speech and the theory of the polyphony of Bakhtin, in the Applied Linguistics area, accomplished with Communication beddings as the agenda-setting. The results ended to a good understanding about the ideology and power´s influence and chaining in the speeches formations as well as to comprehend peoples concept in an environment of almost-mediated interaction, bringing a media look about polyphony in the bakhtinian mold, besides showing how all these questions interferes with the half-barren the Northeast media´s vision on the subject

Na trilha do poético: um caso de angústia da influência

Diese These besteht aus der Analyse der Enteignungsverhältnisse und der Misselung, welche in den Texten der Ursprung des Kunstwerkes und die Hymnen Hölderlins vorkommen. Germanien und der Rhein sind in den 30en-Jahren letzten Jahrhunderts von Martin Heidegger verfasst worden. Ab anwendung der kritischen Methodologia von Harold Bloom und der starken Texgestaltung von Richard Rorty wird es deutlich, dass die Heideggers Lesungen der Hölderlins Poesia als ei Ersatzversuch der von Hegel entwickelte Kulturgeschichte ab deutescher Überlieferung klassicher Studien, die das tragische Erlebnis der alten Griechen als grundlegender Punkt des Westen Daseins vorbringen, verstanden werden können. So verlegt Heidegger die Aufbauachse der Entstehungserzälung des Abendlandes in Richtung Dichtkunst, indem er in seiner Wendung zum Dichterischen gleichzeitig auf der Suche nach einer abweichenden Feststellung der vorherrschaftlichen These ist, in welcher die Tragödie das grosse Antrittsereignis der westlichen Zivilisation darstellt, und darüber hinaus noch der Herstellung einer innigen Verbindung zwischen der Poesie von Hölderlin und Hesiudus, um die Enge der dichterischen Überinstimmung zu zeigen, welche die alten Griechen und die zeitegemässigen Deutschen verbrände. Dieser geistige Aufbau Heideggers hat man somit als ein überholungsversuch Hegels Einfluss und Denkungsart zur Vollendung der von Nietzsche begonnenen Überwindungsaufgabe des Hegelianismus´zu verstehen

A influência do esqueleto açúcar-fostato no transporte da molécula de DNA

This dissertation analyses the influence of sugar-phosphate structure in the electronic transport in the double stretch DNA molecule, with the sequence of the base pairs modeled by two types of quasi-periodic sequences: Rudin-Shapiro and Fibonacci. For the sequences, the density of state was calculated and it was compared with the density of state of a piece of human DNA Ch22. After, the electronic transmittance was investigated. In both situations, the Hamiltonians are different. On the analysis of density of state, it was employed the Dyson equation. On the transmittance, the time independent Schrödinger equation was used. In both cases, the tight-binding model was applied. The density of states obtained through Rudin-Shapiro sequence reveal to be similar to the density of state for the Ch22. And for transmittance only until the fifth generation of the Fibonacci sequence was acquired. We have considered long range correlations in both transport mechanism

Influência da filogenia em redes de interações ecológicas

In this thesis we deal with a class of composed networks that are formed by two tree networks, TP and TA, whose end points touches each other through a bipartite network BPA. We explore this network using a functional approach. We are interested in what extend the topology, or the structure, of TX (X = A or P) determines the links of BPA. This composed structure is an useful model in evolutionary biology, where TP and TA are the phylogenetic trees of plants and animals that interact in an ecological community. We use in this thesis two cases of mutualist interactions: frugivory and pollinator networks. We analyse how the phylogeny of TX determines or is correlated with BPA using a Monte Carlo approach. We use the phylogenetic distance among elements that interact with a given species to construct an index κ that quantifies the influence of TX over BPA. The algorithm is based in the assumption that interaction matrices that follows a phylogeny of TX have a total phylogenetic distance smaller than the average distance of an ensemble of Monte Carlo realizations generated by an adequate shuffling data. We find that the phylogeny of animals species has an effect on the ecological matrix that is more marked than plant phylogeny

Influência da fadiga no comportamento neuromuscular do quadríceps femoral, após reconstrução do ligamento cruzado anterior

Muscle fatigue is a phenomenon that promotes physiological and biomechanical disorders and their changes in healthy subjects have been widely studied and have significant importance for care in preventing injuries, but we do not have many information about its effects in patients after ACL reconstruction. Thus, this study is to analyze the effects of fatigue on neuromuscular behavior of quadriceps after ACL reconstruction. To reach this objective, participants were forty men, twenty healthy (26,90 ± 6,29 years) and twenty after ACL reconstruction (29,75 ± 7,01 years) with a graft of semitendinosus and gracilis tendons, between four to six months after surgery. At first, there was an assessment of joint position sense (JPS) at the isokinetic dynamometer at a speed of 5°/s and target angle of 45° to analyze the absolute error of JPS. Next, we applied the a muscle fatigue protocol, running 100 repetitions of isokinetic knee flexion-extension at 90°/s. Concurrently with this protocol, there was the assessment of muscle performance, as the peak torque (PT) and fatigue index, and electromyographic activity (RMS and median frequency). Finally, we repeated the assessment of JPS. The statistical analysis showed that patients after ACL reconstruction have, even under normal conditions, the amended JPS compared with healthy subjects and that after fatigue, both have disturbances in the JPS, but this alteration is significantly exacerbated in patients after ACL reconstruction. About muscle performance, we could notice that these patients have a lower PT, although there are no differences between the dynamometric and EMG fatigue index. These findings show the necessity about the cares of pacients with ACL reconstruction in respect of the risks of articulate instability and overload in ligamentar graft
