The (well) informed piano : internalization and growth process

The subject matter of this book is about piano methodology, including technical, musical, artistic, ethical and philosophical issues and reflections. The purpose of this work is to share a personal professional experience insight in the field of piano performance. This text assumes a certain continuity to the major contributions of artists like Ludwig Deppe, Tobias Matthay, Grigory Kogan, Heinrich Neuhaus and George Kochevitsky. At the same time, it tries to integrate and complement this selected literature, bringing new ideas and hints to specific professional issues.

Mining protein structure data

The principal topic of this work is the application of data mining techniques, in particular of machine learning, to the discovery of knowledge in a protein database. In the first chapter a general background is presented. Namely, in section 1.1 we overview the methodology of a Data Mining project and its main algorithms. In section 1.2 an introduction to the proteins and its supporting file formats is outlined. This chapter is concluded with section 1.3 which defines that main problem we pretend to address with this work: determine if an amino acid is exposed or buried in a protein, in a discrete way (i.e.: not continuous), for five exposition levels: 2%, 10%, 20%, 25% and 30%. In the second chapter, following closely the CRISP-DM methodology, whole the process of construction the database that supported this work is presented. Namely, it is described the process of loading data from the Protein Data Bank, DSSP and SCOP. Then an initial data exploration is performed and a simple prediction model (baseline) of the relative solvent accessibility of an amino acid is introduced. It is also introduced the Data Mining Table Creator, a program developed to produce the data mining tables required for this problem. In the third chapter the results obtained are analyzed with statistical significance tests. Initially the several used classifiers (Neural Networks, C5.0, CART and Chaid) are compared and it is concluded that C5.0 is the most suitable for the problem at stake. It is also compared the influence of parameters like the amino acid information level, the amino acid window size and the SCOP class type in the accuracy of the predictive models. The fourth chapter starts with a brief revision of the literature about amino acid relative solvent accessibility. Then, we overview the main results achieved and finally discuss about possible future work. The fifth and last chapter consists of appendices. Appendix A has the schema of the database that supported this thesis. Appendix B has a set of tables with additional information. Appendix C describes the software provided in the DVD accompanying this thesis that allows the reconstruction of the present work.

SEROLOGICAL DETECTION OF HEPATITIS A VIRUS IN FREE-RANGING NEOTROPICAL PRIMATES (Sapajus spp., Alouatta caraya) FROM THE PARANÁ RIVER BASIN, BRAZIL

Nonhuman primates are considered as the natural hosts of Hepatitis A virus (HAV), as well as other pathogens, and can serve as natural sentinels to investigate epizootics and endemic diseases that are of public health importance. During this study, blood samples were collected from 112 Neotropical primates (NTPs) (Sapajus nigritus and S. cay, n = 75; Alouatta caraya, n = 37) trap-captured at the Paraná River basin, Brazil, located between the States of Paraná and Mato Grosso do Sul. Anti-HAV IgG antibodies were detected in 4.5% (5/112) of NTPs, specifically in 6.7% (5/75) of Sapajus spp. and 0% (0/37) of A. caraya. In addition, all samples were negative for the presence of IgM anti-HAV antibodies. These results suggest that free-ranging NTPs were exposed to HAV within the geographical regions evaluated.

Correlação entre condições de saneamento básico e parasitoses intestinais na população de Assis, Estado de São Paulo

Foi estudada a distribuição dos enteroparasitos mais freqüentes na população de Assis, São Paulo, de 1990 a 1992. Foram analisados 18.366 exames oriundos de seis postos de atendimento sanitário (PAS): Vila Marialves, Vila Progresso, Centro, Vila Xavier, Vila Fiúza e Vila Bonfim. A prevalência de enteroparasitoses geral foi 23,3%. Os enteroparasitos mais encontrados foram: Giardia intestinalis (8,7%), Ascaris lumbricoides (5,5%), Trichuris trichiura (2,4%) e Hymenolepis nana (1,9%). Na Vila Marialves, região de baixo nível sócio-econômico essas freqüências foram, respectivamente: 17%; 13,1%; 5,9% e 4,2%. A faixa etária 3 a 12 anos apresentou maior número de indivíduos parasitados. Estabeleceu-se uma correlação entre as condições de saneamento básico, expressos pelo número de ligações de água e esgoto, e a freqüência de parasitoses. Houve queda na freqüência de parasitoses nos PAS entre 1990 e 1992, coincidindo com o aumento do número de ligações de água e esgoto nestas regiões.

Emissão e omissão no Wittgenstein de Rorty

O trabalho de Ludwig Wittgenstein é uma das mais constantes referências no percurso de Richard Rorty, cujos escritos, por sua vez, assumem um papel de relevo no âmbito do comentário wittgensteiniano. Apesar de abundarem os textos que contestam a leitura que Rorty faz de Wittgenstein, não há nenhum que, de forma global, vise analisar o modo como se desenrola tal leitura. Na parte I, faremos, pois, o retrato da leitura que Rorty faz de Wittgenstein, recorrendo aos três artigos que o norte-americano escreveu sobre o pensador austríaco: “Keeping Philosophy Pure: an Essay on Wittgenstein”, publicado em 1982, no livro Consequences of Pragmatism – Essays 1972-1980; “Wittgenstein, Heidegger, and the reification of language”, publicado, em 1991, no segundo volume dos Philosophical Papers de Rorty; e “Wittgenstein and the Linguistic Turn”, publicado em 2007, no quarto e último volume dos Philosophical Papers. Na parte II, procuraremos pôr em relevo três implicações democráticas do pensamento de Ludwig Wittgenstein, as quais, apesar de não mencionadas por Rorty, não só são compatíveis com o seu pragmatismo como, sobretudo, estabelecem uma conexão que Rorty não fez: aquela que liga o Rorty leitor de Wittgenstein ao Rorty que reflecte sobre os fundamentos da democracia. A defesa da democracia e a leitura de Wittgenstein surgem separadas no pensamento de Rorty; a sugestão que permeia a parte II é que teria sido mais frutífero, para Rorty e de acordo com os seus próprios parâmetros, estabelecer uma conexão entre o trabalho de Wittgenstein e a reflexão acerca da democracia. Argumenta-se que a pertinência de tal conexão permite concluir que Rorty rejeitou precipitadamente os termos terapia, metafísica e humanidade, na medida em que os mesmos, desde que entendidos num determinado sentido, são úteis para pensar a democracia como exigindo uma certa terapia, como o sistema que privilegia uma pluralidade de metafísicas ou como o modo de convívio no qual a humanidade consiste num espaço relacional de intercâmbio linguístico.

A cor como abrigo: a arquitectura como cuidado

A presente tese intitulada “A cor como abrigo: a arquitectura como cuidado” tem por objectivo fortalecer a ligação entre a “Teoria das Cores” de Goethe e a arquitectura. Para isso a nossa estratégia foi recuperar os conceitos de espaço e corpo. Ambos começam por ser tomados como realidades físicas mas pouco a pouco vai-se mostrando que tal coisa como uma abordagem ‘puramente física’ do espaço e do corpo não é possível - talvez porque não exista. Mesmo a medicina (ao contrario do que possamos pensar primeiro) é uma ciência que não só reconhece o carácter diáfano do corpo como diariamente luta para ir além de uma concepção do corpo enquanto coisa física por perceber que o corpo é determinado por formas e funções mas sobretudo como tomado por forças. Um exemplo extremo desta interacção entre espaço e corpo (ligados através da arquitectura), onde o carácter diáfano de ambos ganha evidência, é na arquitectura de hospitais, que abordamos por último: “o que é um espaço vivido que tem por principal função restaurar o corpo do seu estado de doença?” As referencias principais são J.W. Goethe, Ludwig Wittgenstein, Edmund Husserl, Gilles Deleuze, Christian Norberg- Schulz, Frank Lloyd Wright and Tadao Ando. *********************************************************************This PhD research thesis titled: "Colour as shelter: architecture as care" has as its main goal to strengthen an existing relation between Goethe's Theory of Colours and Architecture. In order to do that our strategy was to use space and body as guiding concepts. Both start as being considered from a pure physical point of view but as our theme develops we see that a “pure physical point of view” concerning space and body it is not possible – perhaps because it does not exist. Medicine (unlike we may think at first) it is a science that not only acknowledges the diaphanous character of the body as daily, tries to go beyond the conception of body as physical thing understanding that the body is determined by forms and functions but mostly taken by forces. An extreme example of the interaction between space and body (linked through architecture), where the diaphanous character of both is evident, is Healthcare architecture: "what is a lived space that has as main function to restore the body of its illness"? Main references are: J.W. Goethe, Ludwig Wittgenstein, Edmund Husserl, Gilles Deleuze, Christian Norberg-Schulz, Frank Lloyd Wright and Tadao Ando.

Botnet cluster identification

Botnets are a group of computers infected with a specific sub-set of a malware family and controlled by one individual, called botmaster. This kind of networks are used not only, but also for virtual extorsion, spam campaigns and identity theft. They implement different types of evasion techniques that make it harder for one to group and detect botnet traffic. This thesis introduces one methodology, called CONDENSER, that outputs clusters through a self-organizing map and that identify domain names generated by an unknown pseudo-random seed that is known by the botnet herder(s). Aditionally DNS Crawler is proposed, this system saves historic DNS data for fast-flux and double fastflux detection, and is used to identify live C&Cs IPs used by real botnets. A program, called CHEWER, was developed to automate the calculation of the SVM parameters and features that better perform against the available domain names associated with DGAs. CONDENSER and DNS Crawler were developed with scalability in mind so the detection of fast-flux and double fast-flux networks become faster. We used a SVM for the DGA classififer, selecting a total of 11 attributes and achieving a Precision of 77,9% and a F-Measure of 83,2%. The feature selection method identified the 3 most significant attributes of the total set of attributes. For clustering, a Self-Organizing Map was used on a total of 81 attributes. The conclusions of this thesis were accepted in Botconf through a submited article. Botconf is known conferênce for research, mitigation and discovery of botnets tailled for the industry, where is presented current work and research. This conference is known for having security and anti-virus companies, law enforcement agencies and researchers.

Serological evidence for Saint Louis encephalitis virus in free-ranging New World monkeys and horses within the upper Paraná River basin region, Southern Brazil

Introduction Saint Louis encephalitis virus (SLEV) primarily occurs in the Americas and produces disease predominantly in humans. This study investigated the serological presence of SLEV in nonhuman primates and horses from southern Brazil. Methods From June 2004 to December 2005, sera from 133 monkeys (Alouatta caraya, n=43; Sapajus nigritus, n=64; Sapajus cay, n=26) trap-captured at the Paraná River basin region and 23 blood samples from farm horses were obtained and used for the serological detection of a panel of 19 arboviruses. All samples were analyzed in a hemagglutination inhibition (HI) assay; positive monkey samples were confirmed in a mouse neutralization test (MNT). Additionally, all blood samples were inoculated into C6/36 cell culture for viral isolation. Results Positive seroreactivity was only observed for SLEV. A prevalence of SLEV antibodies in sera was detected in Alouatta caraya (11.6%; 5/43), Sapajus nigritus (12.5%; 8/64), and S. cay (30.8%; 8/26) monkeys with the HI assay. Of the monkeys, 2.3% (1/42) of A. caraya, 6.3% 94/64) of S. nigritus, and 15.4% (4/26) of S. cay were positive for SLEV in the MNT. Additionally, SLEV antibodies were detected by HI in 39.1% (9/23) of the horses evaluated in this study. Arboviruses were not isolated from any blood sample. Conclusions These results confirmed the presence of SLEV in nonhuman primates and horses from southern Brazil. These findings most likely represent the first detection of this virus in nonhuman primates beyond the Amazon region. The detection of SLEV in animals within a geographical region distant from the Amazon basin suggests that there may be widespread and undiagnosed dissemination of this disease in Brazil.
