[EN] The cultural manifestation of the Arican indigenous people from Chile, through the designs found in
their garments was analyzed. Comparing their techniques of mosaic formation, using geometric transformations
(bijection plans in itself ), it was investigated whether, mathematically, its evolution could be
explained. The mosaics, as well as the known works of Escher, are constructed from the application of
translations, rotations, reflections or slip reflections of an initial motif (a rosette). With similar purpose
—understanding the relationship between music and the evolution and complexity of a possible mathematical
representation— were analyzed the geometric transformations and excerpts from three works of
Johann Sebastian Bach. It is concluded,...

[EN] This work aimed application of a methodology for calculating and plotting spatial distribution of water
surplus by processing meteorological data in Geographic Information Systems. In this experiment, we used
precipitation and temperature data collected from weather stations, as well as elevation data from Shuttle
Radar Topography Mission, SRTM. Monthly input data from the specific comments was use for surface
meteorological variables generation. The algorithm for calculating the water surplus based on pre-existing
developments, using the equations of fluid balance of Thornthwaite & Mather. We observed both a good
performance of the algorithms and its replicability. However, over the results obtained in this work for

[EN] The physical object of watershed is so important for hydrological monitoring as their concept is for education
in natural disasters. The open library HydroC promotes the delineation of watersheds from relatively
simple functions, developed for educational purposes. A case study was done with students of Introduction
to Computer Science with an undergraduate degree in Environmental Engineering. The creation of
HydroC and its delivering in a collaborative, free and open platform make this proposal an interesting
alternative education resource about natural disasters.

[EN] In a social-environmental modeling course, students need to learn complementary skills
that include the conceptualisation of a model, different modeling paradigms, computer programming,
and the process of rigorously converting ideas and data into a computational
program using a given toolkit. Such topics need to be taught in parallel in order to keep
a heterogeneous audience motivated. Based on the experience with multidisciplinary audiences,
this paper describes a socio-environmental modeling course that explores three
modeling paradigms: System dynamics, Cellular automata, and Agent-based modeling.
We also present a small tutorial with some examples developed for the course.

[EN] Flood is one of the most frequent natural disaster in Brazil. The watercourses classification in the watershed’s
drainage system is one of the resources of the Hydrological Intelligence - essential to natural
disasters monitoring and early warning. Exclusively based on free files and softwares, it is presented a set
of procedures for Strahler classification of a hydrography, with results presented for rivers with meaningful
history and risk of natural disasters: Itaja´ı, Paraiba do Sul and Doce. The results presentation, with
possibilities for education in natural disasters, is done on a free Geographical Information System (QuantumGIS)
and on an innovative platform (SALVAR-Cemaden), which is aimed to...

[EN] Mathematical models are important tools for environmental management and risk assessment. Predictions
about the toxicity of chemical mixtures must be enhanced due to the complexity of effects that can
be caused to the living species. In this work, the environmental risk was accessed addressing the need
to study the relationship between the organism and xenobiotics. Therefore, five toxicological endpoints
were applied through the WTox Model, and with this methodology we obtained the risk classification of
potentially toxic substances. Acute and chronic toxicity, citotoxicity and genotoxicity were observed in the
organisms Daphnia magna, Vibrio fischeri and Oreochromis niloticus. A case study was conducted with
solid wastes from...
