This article demonstrates the existence of black families and the presence of children from these families in public schools of Maranhão, in the nineteenth century. Based on a conjectural methodology newspapers ads of the nineteenth century were consulted and also codices relating to records of baptism, marriage, and documentation of the Government Secretary, located in the Public Archives of the State of Maranhão and Public Library Benedito Leite.

Trichodinids are ciliated protozoa that are widely known as one of the main groups of fish parasites. The genus Trichodina presents the greatest species diversity. However, records of Paratrichodina species are scarce, and little is known about their pathogenicity in hosts. The present study provides new records of Paratrichodina africana Kazubski and El-Tantawy (1986) in Nile tilapia from South America and descriptions of pathological changes and seasonality. A total of 304 farmed fish were examined. From gill scraping, parasites were identified using Klein's nitrate impregnation method. Gill samples were fixed for histopathological analysis. Small trichodinid found in this study have a prominent blade apophysis and narrow central part and blade shape that corresponds to the characteristics of P. africana Kazubski and El-Tantawy (1986). Gill lesions were proportional to parasite intensity, in which the gill tissue was compromised in heavy infestation. Proliferative disturbances were found, including epithelial hyperplasia, desquamation, and mononuclear and eosinophilic infiltrate that culminated in necrosis. We did not observe a seasonality effect on the occurrence of P. africana. This ciliated protozoan causes compromised respiratory capacity that leads to severe gill lesions and currently is an important pathogen that afflicts intensive tilapia cultures in Brazil. © 2013 Elsevier B.V.

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.

The fractal geometry of nature is seen in organizations and has set handcrafted artifacts, among them African Kente cloth traditionally produced by Ewe and Ashanti of West Africa. Incorporating parameters also classify products as carriers of fractal geometry, the Kente fabrics exhibit built from geometric shapes classified as seeds or unique architecture. This article aims to analyze examples of Kente cloths and establish the existence of geometric structures formed from a parent cell, exposing how this cell and how its architecture and formed patterns are maintained throughout the finished product.
