Extraindo áudio de um CD com Windows Media Player

O professor, sentado diante de um computador, explica como os alunos devem proceder para extrair áudio de um CD para arquivos do computador utilizando o software Windows Media Player. São alternadas imagens do professor falando e da tela do computador onde ele realiza uma demonstração da atividade em questão. Após extrair uma música do CD, o professor abre o arquivo de áudio no software Audacity para visualizar a representação gráfica das ondas sonoras da música.

Estratégias internacionais da fruticultura do RN: o caso finobrasa processo e evolução

The present inquiry has as main objective to understand the process of formation of the international strategies of the exporting companies of fruits of the RN through the theory of the resource dependence. Aiming at to clarify as the companies they can carry through the process of internationalization through this theory had been study the behavior and economic theories of the process of internationalization of companies. Amongst the economic theories they are distinguished the eclectic paradigm of Dunning (1958), Vernon (1669) through the theory of the cycle of the product and Bucley and Casson (1979) with the theory of the international operations. In the mannering boarding they had been investigated the school of Upsala through Johanson and Valnhe (1977) with the concept of the increasing of the markets and in the distance psychic starts and the interaction of the purchaser-salesman of Hallen and Wiedersheim-Paul (1979). In this perspective it observes main the occured changes in the organization in function of this process, following the rules observed by the gradual ingression in the international market, having as base ways of entrances in the external market used by these companies, in view of the frist phase that the company presents of businesses. Ahead of you analyze of these theories the study searches to analyze the convergence of the concepts proclaimed for the theory of the dependence of resources (PFEFFER; SALANCIK, 1978). and strategies of internationalization of the companies. The research is characterized as qualitative case study which adopts and exploratory and analytical type, retrospective matrix. The adopted strategy is of case study and the unit of analysis consisting of the Finobrasa, pertaining company to the Vicunha Group. The main method of collection of data was halfstructuralized interview allied the documentary research that together had presented an empirical perspective of the internationalization process. The analysis and quarrel of the results understand the description and the interpretation of the one of the information through the technique of analyzes of content. Initially the historical of the exportation of fruits of the Rio Grande do Norte with the focus in the region Açu/Mossoró is presented and after that the information of the Finobrasa are presented as base of the study. The main events are identified that had constituted the phases of the strategical model of the company. It was observed that the dimensions most excellent amongst those proclaimed by the School of Uppsala had been the learning, staffs and the step-starts is sufficiently gifts in the reality of the company, as well as the aspects of strategical alliances since the consolidated relationship of the Vicunha Group create a more solid trajectory in the international market allied the conditions created windows of marked . One understands, therefore, that the investigated process still has base the theoretical theories of the internationalization strategies corroborating for the theoretical convergence of the rules proclaimed for the theory of the dependence of resources.

Sensitivity evaluation of a single-step PCR assay using Ehrlichia canis p28 gene as a target and its application in diagnosis of canine ehrlichiosis

O objetivo deste estudo foi aperfeiçoar um ensaio de PCR que amplificasse um fragmento de 843 pares de bases do gene p28 da Ehrlichia canis e compará-lo com outros dois métodos de PCR utilizados para amplificar partes do gene 16S rRNA e dsb do gênero Ehrlichia. Amostras sanguíneas foram colhidas de cães com diagnóstico clínico de erliquiose. A amplificação do gene p28 pela PCR produziu um fragmento de 843pb e esse ensaio permitiu a detecção do DNA de um parasita dentre 1 bilhão de células. Todas as amostras positivas detectadas pela PCR baseada no gene p28 foram também positivas pela nested PCR para detecção do gene 16S rRNA e também pela PCR dsb. Dentre as amostras negativas para a PCR p28, 55,3% foram co-negativas, mas 27,6% foram positivas pela PCR baseada nos genes 16S rRNA e dsb. A PCR p28 parece ser um teste útil para detecção molecular de E. canis, entretanto otimizações na sensibilidade nesta PCR são necessárias, para que esta técnica se torne uma importante alternativa no diagnóstico da erliquiose canina.

Confinement of neutral fermions by a pseudoscalar double-step potential in 1+1 dimensions

The problem of confinement of neutral fermions in two-dimensional space-time is approached with a pseudoscalar double-step potential in the Dirac equation. Bound-state solutions are obtained when the coupling is of sufficient intensity. The confinement is made plausible by arguments based on effective mass and anomalous magnetic interaction.

Scattering of neutral fermions by a pseudoscalar potential step in two-dimensional spacetime

The problem of scattering of neutral fermions in two-dimensional spacetime is approached with a pseudoscalar potential step in the Dirac equation. Some unexpected aspects of the solutions beyond the absence of Klein's paradox are presented. An apparent paradox concerning the uncertainty principle is solved by introducing the concept of effective Compton wavelength. Added plausibility for the existence of bound-state solutions in a pseudoscalar double-step potential found in a recent Letter is given. (C) 2003 Elsevier B.V. B.V. All rights reserved.

On the scattering of massive spinless bosons by a nonminimal vector smooth step potential

The Duffin-Kemmer-Petiau (DKP) equation for massive spinless bosons in the presence of a nonminimal vector smooth step potential is revised. The problem is mapped into a Sturm-Lionville equation. The reflection and transmission coefficients are obtained and discussed in detail. Furthermore; we show that Klein's paradox does not show its face in this sort of interaction.
