17. DNA repetitivo e seu papel na estrutura cromossômica terminal em Rhynchosciara americana (Diptera: Sciaridae) / The role of repetitive DNA in the chromosome termini of Rhynchosciara americana (Diptera: Sciaridae)
The chromosomal localization of ribosomal DNA (rDNA) was studied in polytene and diploid tissues of four sciarid species, Trichosia pubescens, Rhynchosciara americana, R. milleri and Schwenkfeldina sp. While hybridization to mitotic chromosomes showed the existence of a single rDNA locus, ribosomal probes hybridized to more than one polytene chromosome regio

18. Realce de contraste em imagens digitais usando equalização de histograma
Nowadays devices are able to capture and process images from complex surveillance monitoring systems or from simple mobile phones. In certain applications, the time necessary to process the image is not as important as the quality of the processed images (e.g., medical imaging), but in other cases the quality can be sacrificed in favour of time.This thesis f

22. Estudo de dois grupos de elementos de cana-de-açúcar homológos à superfamília hAT de transposons / Studies on hAT-like transposases in sugarcane superfamily
Transposable elements (TEs) are mobile genetic sequences. Their mutagenic capacity makes them important sources of variation in the genomes. These elements have another important evolutionary role as donors of functional protein domains in the formation of new genes. 276 cDNA clones homologous to TEs were previously identified in the Brazilian Sugarcane Expr
