A (des)construção da imagem do sujeito professor na mídia: evidências da materialização de valores sociais

The main objective of this study focuses on investigate how the style of the Conhecimento Prático Língua Portuguesa magazine, from Escala publisher, reveals a materialization, in its wordings, of social values that surround our society regarding the teaching class. Besides, we thought about the construction of an other - teacher - by means of the I speech (the enunciator). Furthermore, we reflected on how happens the genre opinion article handling and whether there is, when aimed to the teaching class. All these questions were discussed under the perspective of Bakhtin's theory, focusing our analysis in the wording notions, dialogism, style and speech genres. Our analysis indicates a materialization of social values in syntactic issues and a hybridization of genres when the addressee is a teacher

Localizador de faltas por ondas viajantes em linhas de transmissão

It is important to ensure smoothly operation of a transmission line, sending energy to the consumption centers with minimal interruptions and safer. With this necessity, the fault location techniques have grown, in order to mitigate the impact of the fault and its correction can be more quickly and accurately. This paper presents a comparison between two different techniques of fault location, the fault location by impedance method, which uses the line parameters, the impedance per distance, voltage and current signals, and the other is the traveling wave method, which uses only a very fast analysis of time, synchronization and length between the line ends, do not using voltage and current values, but the temporal perception of the fault. Using travelling waves fault detection makes the previous knowledge of line parameters obsolete, which helps a lot network technicians and engineers with a quick and easy analysis. The methods are simulated in ATP Draw software, so both algorithms can be evaluated for their effectively and accuracy
