Redações de vestibular: a materialização da relação entre leitura e escrita e o diálogo com a coletânea

This work aims to understand in what way the relation between reading and writing works in the writing tests of two major entrance exams from the state of São Paulo, used as a form of admission to two great universities - UNICAMP and UNESP -, as well as analyze in what way the candidates who got grades above the average dialogue with the collection of texts which is offered in the writing test proposal. In order to found these questions on theoretical material, we have done some reading of the Bakhtin circle to understand the questions that are related to the dialogism and had support in other linguists to solidify our interpretations and analyses. We understood, after the studies and analyses, that the materialization of the relation between reading and writing is present in the majority of the texts used as the corpus of our work and that the dialogue with the collection of texts is very appreciated and present in the texts that got the highest grades or were considered above the average. The writing test has always had an unique importance in the selection processes to admission to undergraduate courses, and we believe that the analyses that were proposed here can help students and teachers to better understand the valuation which is attributed to the relation between reading and writing and the use of the collection of texts in the elaboration of a text in the entrance exams

Avaliação da resistência à corrosão da liga Ti-30Ta submetida a diferentes taxas de deformação visando aplicações biomédicas

This study aims to evaluate the corrosion resistance of Ti-30Ta alloy when subjected to different strain rates. Samples of the alloy Ti-30Ta were obtained from the melting of pure elements in the arc furnace in inert atmosphere (argon gas). Then, the samples were subjected to a thermal treatment and to cold worked to obtain bars. After forging, the samples were machined in accordance with ASTME9-09 standard for carried out compression tests. To microstructural characterization, samples were sectioned longitudinal and transversally and embedded in resin. After, the wet sanding and polishing were performed, followed by a chemical attack, in order to study the microstructure under an optical microscope. Microhardness was measured on the samples that were subjected to microstructural characterization by using microhardness tester. Phases were evaluated by x-rays diffraction. Corrosion tests were carried out to evaluate the influence of deformation on the corrosion resistance. Results show that microstructure was not influenced by deformation

Paralisia cerebral: efeitos da escrita sobre a escrita

The aim of this research was to apprehend the effects of text reading in S.'s writing productions, a child in literacy process. S. is a child who can't speak or write by her own due to a dystonic quadriplegic CP. S. communicates with Blissymbols which were introduced in a school-clinic in São Paulo city when she was six years old. At the same time the literacy process took place and she indicated symbols, letters and numbers in a board by scanning. The teacher related S.'s difficulties concerning reading activities, so a weekly activity was proposed by the speech therapist in the classroom. The teacher and her assistant participated in the activity. A cutout of the activity involving a book reading when S. was between eight years and seven months old and nine years and one month old was analysed. The research was based in Borges (2006) grounded in The Brazilian Interactionism according to De Lemos (1992; 1995 and others) and proposes a literacy process among students from the first series in a regular school by the reading of different texts. The activity guided by the speech therapist took place side by side with the literacy program guided by the teacher and resulted in various S's text productions. The data was collected through film transcriptions from the activities in the classroom and from materials produced by S. through the reading of the chosen book. These data integrates NALíngua-CNPq databases coordinated by Dr. Alessandra Del Ré whose aim is to investigate the language acquisition process. S.'s reading and writing acquisition occurred in a singular way, affected by the using of Blissymbols that became S.'s speech modality: a written-speech with symbols and alphabetic writing

Mídias na educação matemática: projeto CONDIGITAL

This work aims to understand the multimedia Learning Objects (LO's) developed within the CONDIGITAL project, subsidized by the federal government. The CONDIGITAL aimed to encourage the production and the use of media in teaching in high school classrooms. This work presents a reflection on the contribution of media to the construction of significant learning of student users. The research was conducted through a literature study. Therefore, it was considered the work of some researchers related to the study of the potential of these technologies in education, such as Valente (1995), Tauroco (2007) and Mussoi (2010). These readings made possible to discern some common evaluation criteria that may be used as parameters to analyze the quality of these media as educational tools. The theme of exploration is guided by a research on the motivation of the mentioned project and on its amplitude and its results, which is directed later to the LO's developed by UNICAMP team, particularly in the Mathematics productions developed by the M³ project, some of the which are presented and evaluated in this monograph

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
