This invention relates to an apparatus and method for improving detection by equipment used to detect magnetic susceptibility. The advantages provided are related to different factors, such as reduced instrumentation cost, performance in terms of stability and sensitivity, etc. The devices may be used, for example, to detect magnetic tracers and markers in the gastrointestinal tract of animals and humans. They can be used in research and/or for diagnostic purposes using information related to a variety of parameters of the gastrointestinal tract, such as, pharyngeal and oesophageal transit time, gastric emptying and motility, colonic motility, inter alia.

Patente de invenção de métodos para processamento de imagens obtidas a partir de amostras preparadas 'cbnforme protocolo para reajízação de teste do cometa, particularmente corado pela prata. Este teste é amplamente utilizado para avaliação de genotoxicidade de substâncias. Há sistemas automatizados que analisam cometas corados por substâncias fluorescentes. A coloração de prata é uma técnica pouco difundida pela falta de tecnologia de análise digital automatizada e tem desempenho semelhante às técnicas com fluorescência, porém, é de baixo custo, rápida execução, não depende de microscópios de fluorescéncia e não utiliza produtos mutagênicos em seu protocolo.

The objective of this study was to define a method for estimating soybean crop area in the Northern Rio Grande do Sul state (Brazil). Overall, six different remote sensing methods were proposed based on spectral-temporal profile and minimum and maximum values of NDVI/MODIS related to the stages of sowing, maximum development and harvesting of soybean areas. The resulting estimates were compared to official crop area data provided by the Brazilian government, using statistical analysis and the fuzzy similarity method. The performance of each method depended on information such as crop size, type of crop management, and sowing/harvesting dates. Regression coefficients of determination and fuzzy agreement values were above 0.8 and 0.45, respectively, for all methods. For operational monitoring of soybean crop area, the empirical threshold applied to the image difference with inclusion of harvest image method was the most effective, producing estimates that matched closely the official data. For spatial analysis the application of multitemporal images classification method is recommended that generated a map of better quality. The efficiency of these methods should be evaluated in the areas of soybean expansion in the state.

Este estudo constitui-se de três momentos principais: a reflexão sobre a historiografia literária de Moçambique (apresentada no capítulo um), as considerações a respeito da fortuna crítica acadêmica monográfica de Mia Couto produzida no Brasil (que abordamos no segundo capítulo) e a análise da autointertextualidade na obra ficcional de Mia Couto (matéria que ocupa os capítulos três e quatro)

A discussion, through a literature review, on the use of photographic documents and Documentary Analysis (DA) for the preservation, description and retrieval of images of pilgrimages in northeastern Brazil, which are archived at the Laboratory of Information Science and Memory (LACIM). The photograph acts as an expression of faith and devotion; it is a witnesses and documents, through images, the records of the day-to-day folk religion in its multiple meanings and situations, linked to the sacred. The DA —as a set of procedures performed after the reading of documents— facilitates the analysed collection location or query through the documentary language. This paper tries to show that the particular form of the information contained in a photographic archive echoes submerged memories of the pilgrims, authenticating a social fact in the country, capturing the sacredness from specific moments of celebration.

Radio Days de Woody Allen est un film de mémoire: le narrateur ressouvient sa enfance et l´influence du radio dans les années 1940 dans le quotidien dans sa famille. Ce film n´est pas une simple reconstitution historique mais un document pour l´histoire, document visuel en potentiel étudié dans les relations cinema, histoire et mémoire. Dans cette perspective l´analyse filmique discute le méthode suggéré par Marc Ferro pour l´analyse du document d´images en mouvement. Le film est, dans nos cas, un écrivain d´histoire et en même temps un support pour la mémoire: mémoire étendu pour Jacques Le Goff et experience collective pour Walter Benjamin.

The objective of this article was to argue how to use images (as films, photos and paintings) and lyrics of musics (as rap) to teach History of the African and Afro- Brazilian culture in classroom. Demonstrating how the procedures had been worked in classroom, at Municipal School of Basic Education (EMEF) “Maria Pavanatti Favaro”, located in Campinas City, in the State of São Paulo-Brazil, and the results that had been reached with the use of those resources.
