A influência da música nas atividades físicas e sua impressão no corpo e nos estados de ânimo

Numerous studies in physical education and music's area have been conducted to improve the quality of life and health of people, all of them under physiological, psychological and social fields. Thus, when properly analyzed, both Areas are connected, because the movement itself, main subject of physical education, has a close proximity to the rhythm, an essential element of music. That's why it is important to discover the benefits of this relationship, because, in many of its practices, physical education makes use of music, for example, in aerobic gymnastic and dance classes. As a consequence, this study aims to investigate, through literature, the influence of music in physical activities and its imprinting in the states of mind and body of practitioners, as well as clarify the criteria for choice of songs that are used in such practice. This research occurred under literary explore, done through theoretical analysis of the thematic. At first place, a contextualization of the auditory system and its relationship with the music and the perception of sound were made, then the main theme was explored. The music, even before generate and influence motor and psychic movements in the human body, is already moving in space, because it is formed through vibrations of molecules. It is decoded first as a movement from the ears, and then decoded as sound, when in the brain. It is important to worry about sounds at high intensities and also with those which are outside the hearing thresholds within physical activities involving music, because they may be harmful to health and also to states of mind. As far as music and movement is concerned, they are closely linked, and the human being has an instinctive sense of rhythm that can be seen when listening to music, because the motor cortex is also activated. Therefore, it is important to work the sound and body movement together, because in practice they are inseparable and they contribute greatly to...

Acrylic resin cytotoxicity for denture base - Literature review

Acrylic resin is a widely used material in clinical practice, and a satisfactory biocompatibility is essential. When the resin polymerization reaction is incomplete, residual monomers are released into the oral cavity. The aim of this study was to evaluate, through a literature review, the cytotoxicity caused by the denture base acrylic resin used, and its components. The selection of published studies was performed on the Pubmed database from January 2008 to July 2013. The keywords used were: cytotoxicity and acrylic resins, cytotoxicity and denture base resins and cytotoxicity and oral prosthesis. Inclusion criteria were: in vitro studies and literature reviews published in English that evaluated the acrylic resin cytotoxicity for denture base and its components. Studies with no reference to the search strategy were excluded. A total of 182 articles were found. Among these, only 13 were included for writing this review. The MTT test is the most common test used to evaluate acrylic resin cytotoxicity. Auto-polymerized resin is more cytotoxic than heat-polymerized resin because of its higher quantity of residual monomers which cause cell and tissue changes in the oral mucosa. However, more studies are necessary for the development of biocompatible materials.

New Business Models And Editorial Exemption: A Study On Service Journalism Based On Ecommerce Operations

The paper presents and discusses business strategies based on the association from journalistic content to new commercial practices in digital media. We describe selected examples from Folha de S. Paulo and El País involving service guides, links and ecommerce advertisements. The employed method provides content analysis to illustrate how the search for new business models in journalism may conduct its commercial activities beyond the conventional sale of advertising and subscriptions, including a discussion on the challenges and implications of this practice. The hypothesis is demonstrated by describing operations for the sale of tickets, books, music, and films related to news features and service journalism contents. The text finally wonders and discusses how such commercial actions may affect editorial autonomy and publishing exemption.

World of Unknown Creatures and Their Hidden Works

What is the most mysterious feelings in mankind? What is the most general way by which every mankind is subject to change. Well monotonous, and steady life where someone does the same kind of work at same pace in same time, without any change of events, creates the burdensome feeling in a person. Yet people are unaware of it. We don't know where are we going, yet we go at the same pace, since in practical sense we are getting some credit for something. But the thing how much do we keep up, and maintain the balance in nature, so that we can really feel the value and the quality of life, and know the exact happiness of fulfilling the work. But if its totally becomes materialistic, and emotional aspect goes away from human beings, where social talking never goes away from your duties. Then!!!! ... I mean there is no need of human beings. If we are so developed, right from past few centuries and our domination, had created a modern social world, then we can create all kinds of devices and software which can handle all the works for which the people don't have to stay overtime just to finish that. I mean in that way human life will move through some progress, and will have some development. But the environment where we are living nothing new or development is taking place as the work becomes a duty for human being but not to machine which should be given some task to be completed.So all those devices are not in the society, since human being is already taking charge if it.

THE FLUTE MUSIC OF PAUL DESENNE: A COMPARATIVE ANALYTICAL STUDY OF REPRESENTATIVE WORKS

The significance of the works by Venezuelan-born composer Paul Desenne lies in his unique compositional style that incorporates elements of Latin American folk, pop, and traditional music within the framework of the Western European tradition. His works, though easily classified as art music, nevertheless gain much of their emotional and referential meaning through this rich borrowing. This document focuses on three of Desenne’s flute pieces: the Solo Flute Sonata (2001), Gurrufío for flute orchestra (1997), and Guasa Macabra for flute and clarinet (2003). It provides an analysis of the three works, examining formal, structural, motivic, and rhythmic aspects. Scores and interviews with the composer have been employed as primary sources. Bibliographical material closely related to his music and other secondary sources support this analytical approach. This document also provides an introduction and stylistic discussion of Desenne’s other pieces that incorporate the flute. Chapter one consists of an introduction to Desenne’s life and general considerations of his musical style. Each of the following three chapters focuses on one the three aforementioned flute works, including information about the composition and premiere of each piece as well as analysis and an examination of its incorporation of traditional folk elements. The final chapter presents an introduction to and stylistic discussion of the other flute pieces by this composer. This study intends to provide a basic understanding of Desenne’s flute music, including general characteristics of his musical style, paving the way for further investigation of Desenne’s music, and flute music in particular.

Literacy Research: Issues of Authority, Ownership, and Representation

With the “social turn” of language in the past decade within English studies, ethnographic and teacher research methods increasingly have acquired legitimacy as a means of studying student literacy. And with this legitimacy, graduate students specializing in literacy and composition studies increasingly are being encouraged to use ethnographic and teacher research methods to study student literacy within classrooms. Yet few of the narratives produced from these studies discuss the problems that frequently arise when participant observers enter the classroom. Recently, some researchers have begun to interrogate the extent to which ethnographic and teacher research methods are able to construct and disseminate knowledge in empowering ways (Anderson & Irvine, 1993; Bishop, 1993; Fine, 1994; Fleischer. 1994; McLaren, 1992). While ethnographic and teacher research methods have oftentimes been touted as being more democratic and nonhierarchical than quantitative methods—-which oftentimes erase individuals lived experiences with numbers and statistical formulas—-researchers are just beginning to probe the ways that ethnographic and teacher research models can also be silencing, unreflective, and oppressive. Those who have begun to question the ethics of conducting, writing about, and disseminating knowledge in education have coined the term “critical” research, a rather vague and loose term that proposes a position of reflexivity and self-critique for all research methods, not just ethnography or teacher research. Drawing upon theories of feminist consciousness-raising, liberatory praxis, and community-action research, theories of critical research aim to involve researchers and participants in a highly participatory framework for constructing knowledge, an inquiry that seeks to question, disrupt, or intervene in the conditions under study for some socially transformative end. While critical research methods are always contingent upon the context being studied, in general they are undergirded by principles of non-hierarchical relations, participatory collaboration, problem-posing, dialogic inquiry, and multiple and multi-voiced interpretations. In distinguishing between critical and traditional ethnographic processes, for instance, Peter McLaren says that critical ethnography asks questions such as “[u]nder what conditions and to what ends do we. as educational researchers, enter into relations of cooperation. mutuality, and reciprocity with those who we research?” (p. 78) and “what social effects do you want your evaluations and understandings to have?” (p. 83). In»the same vein, Michelle Fine suggests that critical researchers must move beyond notions of the etic/emic dichotomy of researcher positionality in order to “probe how we are in relation with the contexts we study and with our informants, understanding that we are all multiple in those relations” (p. 72). Researchers in composition and literacy stud¬ies who endorse critical research methods, then, aim to enact some sort of positive transformative change in keeping with the needs and interests of the participants with whom they work.

Cyclopropane- and spirolimonoids and related compounds from Hortia oreadica

The dichloromethane extract from taproots of Hortia oreadica afforded six limonoids, these are 9,11-dehydro-12 alpha-acetoxyhortiolide A, hortiolide C, 11 alpha-acetoxy-15-deoxy-6-hydroxyhortiolide C, hortiolide D, hortiolide E, 12 beta-hydroxyhortiolide E, in addition to the known limonoid, guyanin. The dichloromethane extract from stems of H. oreadica also afforded two limonoids 9,11-dehydro12 alpha-hydroxyhortiolide A and 6-hydroxyhortiolide C. As a result of this study and literature data, Hortia has been shown to produce highly specialized limonoids that are similar to those from the Flindersia (Flindersioideae). The taxonomy of Hortia has been debatable, with most authors placing it in the Toddalioideae. Considering the complexity of the isolated limonoids, Hortia does not show any close affinity to the genera of Toddalioideae. That is, the limonoids appear to be of little value in resolving the taxonomic situation of Hortia. (C) 2012 Elsevier Ltd. All rights reserved.

A Simple Method to Evaluate, Correlate and Predict Boiling and Flash Points of Alkynes

Boiling points (T-B) of acyclic alkynes are predicted from their boiling point numbers (Y-BP) with the relationship T-B(K) = -16.802Y(BP)(2/3) + 337.377Y(BP)(1/3) - 437.883. In turn, Y-BP values are calculated from structure using the equation Y-BP = 1.726 + A(i) + 2.779C + 1.716M(3) + 1.564M + 4.204E(3) + 3.905E + 5.007P - 0.329D + 0.241G + 0.479V + 0.967T + 0.574S. Here A(i) depends on the substitution pattern of the alkyne and the remainder of the equation is the same as that reported earlier for alkanes. For a data set consisting of 76 acyclic alkynes, the correlation of predicted and literature T-B values had an average absolute deviation of 1.46 K, and the R-2 of the correlation was 0.999. In addition, the calculated Y-BP values can be used to predict the flash points of alkynes.

Extra and intradural spinal Hemangioblastoma

Hemangioblastomas of the central nervous system (CNS) are low-grade highly vascularized tumors that may be sporadic or associated with Von Hippel-Lindau disease. Extradural hemangioblastomas are uncommon and those located extra and intradurally are even rarer. This study uses an illustrative case and literature review to discuss the difficulties to consider the correct diagnosis and to select the best surgical approach. A 57 years-old white male patient presented with myelopathy and right C5 radiculopathy. The images showed a lobulated, hourglass shaped, highly enhanced extra/intradural lesion that occupied the spinal canal and widened the C4-C5 right intervertebral foramen. Total resection of the intradural lesion was achieved through a posterior approach, but the extradural part could only be partially removed. Complete improvement was observed after four months of follow-up and the residual tumor has been followed up clinically and radiologically. Even though the preoperative impression was of a spinal schwannoma, the histopathological examination revealed grade I hemangioblastoma as per WHO. Despite their rarity, current complementary exams allow considering the diagnosis of hemangioblastoma preoperatively. That is essential to a better surgical planning in view of the particular surgical features of this lesion.

On the morphological differentiation between Libinia spinosa and L. ferreirae (Crustacea: Brachyura: Majoidea: Epialtidae)

Libinia spinosa H. Milne Edwards in Guérin, 1832 and L. ferreirae Brito Capello, 1871, inhabit very similar environments, and their geographic and bathymetric distributions overlap for about 3000 km along the southwestern Atlantic. Both species are commonly caught in the same haul and differentiating between them can often be difficult. Traditionally, morphological differentiation between L. spinosa and L. ferreirae has been based exclusively on the number of spines along the median, longitudinal line of the carapace and the development of a process at the anterolateral angle of the basal segment of the antenna. Because Libinia spinosa and L. ferreirae share similar numbers of median spines (7 and 6, respectively), and the number of median spines of the carapace and the process at the anterolateral angle of the basal antennal segment are variable, they are of little value in separating these species. It is shown herein that unequivocal identification can be easily achieved based on features of the male and female thoracic sternum, pereiopod dactyli, and infraorbital notch. A lectotype is designated for L. spinosa and its authorship and date are corrected. Libinia gibbosa A. Milne-Edwards, 1878, is demonstrated to be a junior synonym of L. ferreirae. The holotype of L. gibbosa is figured for the first time.

Musica come Scienza dell'uomo. I caratteri del sapere musicale nel Settecento britannico

The departure point of the present work is the idea that in order to understand what music meant to British society in the Eighteenth-Century an interdisciplinary approach is necessary. Natural philosophy, moral philosophy, musical treatises and histories of music: all these sources concur both to the creation of a new idea about what music and its ‘science’ are, and to question the place which music ought to have in the realm of the Science of Man. The dissertation is divided into two sections. In the first one we will take into account philosophical sources (from John Locke, Joseph Addison and Lord Shaftesbury, to Lord Kames and Adam Smith), and we will examine their thoughts on music. In the second one we will deal with musical sources (from the Treatise of Musick of Alexander Malcom, to the Histories of Music of Charles Burney and John Hawkins) in order to show their connection with the philosophical literature before mentioned. The main aim of the work it to show that the development of specific philosophies of the human mind, such as the ones of John Locke and David Hume, did influence the way in which music was thought. Particularly we will point out the case of Adam Smith’s interpretation of instrumental music, which is heavily indebted to the humeian model of the human mind.

Pädagogische, musikpädagogische und curriculare Semantiken in systemtheoretischer Betrachtung - zum Umgang mit populärer Musik an allgemeinbildenden Schulen in Deutschland nach 1945

Die Dissertation untersucht die geistige Produktion im Erziehungssystem anhand des Unterrichtsgegenstands populäre Musik. Hiermit ist sie im Kernbereich der musikpädagogischen Disziplin angesiedelt – Musik und Schule. Ferner rückt die Festlegung auf populäre Musik den Schüler in seinem Alltagswissen in den Vordergrund der Betrachtung. Die Frage nach dem Umgang mit populärer Musik ist somit indirekt eine Frage nach dem Umgang mit schülernahen Erfahrungswelten in der Schule. Innerhalb dieses Forschungsprofils erhält die Arbeit ihre eigentliche Relevanz - sie zeigt auf, wie eine moderne, selbstreferentielle Musikpädagogik eigene bedeutsame Kommunikationen beobachten kann. Entworfen in Anlehnung an die Systemtheorie nach Niklas Luhmann, werden in der Arbeit die unikalen Reflexionszusammenhänge von Pädagogik und Musikpädagogik anhand der folgenden Operationsfelder offengelegt: pädagogische und musikpädagogische Fachliteratur, Lehrpläne und Schulbücher. Nach Luhmann ist es erforderlich verstehend in die Unikalität systemischer Reflexionsleistungen einzudringen, um inkonsistente Anforderungen an die Aufgabe (Musik-)Erziehung und ihre Gegenstände aufzudecken und zukünftige Systemhandlungen zu optimieren. Die Arbeit ist in drei große historische Zeitblöcke gegliedert, die ihrerseits in verschiedene disziplinäre Operationsfelder unterteilt sind. Mit Hilfe dieser zweidimensionalen historisch-interdisziplinären Sichtweise wird populäre Musik als Bezugsgröße aufgewiesen, an der die zentralen Debatten von Pädagogik und Musikpädagogik kondensieren. Anhand von Schlüsselbegriffen wie Kultur, Gesellschaft und Ästhetik aber auch didaktischen Prinzipien wie Schüler- und Handlungsorientierung oder ganzheitliche (Musik-)Pädagogik lässt sich die Vielfalt historisch gewachsener inkonsistenter/konsistenter Forderungen belegen. Aus den Beobachtungen im Umgang mit populärer Musik werden Aufgaben deutlich, die die Disziplinen, vor allem die Musikpädagogik, in der Zukunft zu leisten haben. Diese beschäftigen sich auf der einen Seite mit dem disziplinären Selbstverständnis und auf der anderen Seite mit unbeantworteten didaktischen Fragestellungen wie den Möglichkeiten und Grenzen des einzelnen populären Musikstücks im konkret-situativen Lernkontext von Musikunterricht.

Narratori degli anni zero. Storia, critica, poetiche

Il lavoro si propone come un’indagine sulla letteratura italiana del primo decennio del XXI secolo, in una prospettiva non di semplice ricognizione ma di individuazione di linee interpretative capaci di ripercorrere un archivio di materiali molto vasto e non ancora chiuso. La prima parte affronta questioni relative a condizioni produttive, ricezione e valutazione critica della letteratura contemporanea. Il primo capitolo è dedicato alla discussione di problemi relativi allo studio della narrativa italiana del XXI secolo a partire dalla definizione utilizzata per riferirsi ad essa, quella di “anni zero”. Il secondo capitolo situa la narrativa contemporanea nelle linee di sviluppo della letteratura italiana degli ultimi trent’anni, a partire da un mutamento del rapporto dello scrittore con la tradizione umanistica che risale all’inizio degli anni ottanta. Il terzo capitolo approfondisce uno dei generi maggiormente praticati: il romanzo storico. Considerato negli anni ottanta e novanta un genere d'evasione e intrattenimento, negli anni zero è divenuto veicolo di punti di vista critici nei confronti delle narrazioni dominanti. La seconda parte è dedicata all’approfondimento di romanzi che raccontano, da un’ottica non testimoniale, gli anni settanta italiani, periodo complesso non solo sul piano evenemenziale, ma anche su quello della rielaborazione artistica. I romanzi su cui si concentra l’indagine offrono un racconto degli anni settanta italiani a partire da un’idea di storia plurale, ricostruita attraverso una molteplicità di voci, che muta a seconda della prospettiva da cui viene affrontata. Le storie false dei romanzi sugli anni settanta non chiedono di essere lette come vere, ma dicono comunque qualcosa di vero sulle modalità attraverso le quali si va costruendo il rapporto con il passato recente, nel più ampio contesto dei percorsi della letteratura italiana di inizio millennio, tra spinte che vanno nella direzione del mantenimento dell’autonomia da parte degli autori e pressioni del mercato editoriale.
