Caracterização hidroquímica do sistema aquífero Tubarão no município de Americana/SP

The growing interest in the use of groundwater resources is directly related to the economic advantages that the groundwater exploitation offers when compared to surface waters. This happens especially in large urban centers, such as the city of Americana / SP, where the rivers are increasingly contaminated by household and industrial waste. Therefore, this study aimed to characterize the Tubarão Aquifer System, in the city of Americana, to identify and evaluate the spatial distribution of different hydrogeochemical facies as well as understand the rock-fluid interaction through the construction of a conceptual hydrogeochemical model. This study was made based on the recognition of the possible chemical reactions that print the chemical characteristics of groundwater in the area. To do the job, there were two water sampling campaigns of all deep wells used by the City of Americana public water supply. From the results of hydrochemical, classification of water was made by Piper and Stiff diagrams as well as geostatistical data using cluster analysis of principal components. Based on information from the profiles obtained from the survey SIAGAS as well as in geological profiles provided by the city of Americana, we sought to detail the subsurface geology of the Subgroup Itararé in the city of Americana. The results obtained allowed the identification of three hydrochemical types in the study area: Bicarbonated calcium-sodium (1), bicarbonate sodium (2) and sodium chloride (3). The waters have bicarbonate alkaline pH to alkaline and can be considered weakly saline, with electrical conductivity values of around 161 mS / cm. Samples classified as sodium bicarbonate average of 174.99 mS / cm. The pH values ranging from 6.74 to 7.99, averaging 7.52. For the group of waters classified as sodium chloride, conductivity average is 164.32 mS / cm and pH values ranging... (Complete abstract click electronic access below)

Estudo comparativo de modelos matemáticos de qualidade de águas superficiais

Surface water quality models have been developed since 1925, when Streeter e Phelps created first order equations that represent the balance between DO and BOD. Since then, and specially after the ‘60s, new computational technologies evolved, making it possible to create more complex models, which try to represent, through mathematics, natural phenomena like eutrophication and rivers self-depuration. As main objective of such models is the understanding of aquatic systems and the relationship between them and the environment, so that it can support decision makers in creating water manage plans and in elaborating environmental projects of such resources. Regarding to that, it is of crucial importance the understanding of the models structures, so that one can choose the most appropriate model for the river in question. While one-dimensional models like QUAL2K are more appropriate for long and narrow rivers, bi- or tridimensional models (CE-QUAL-W2, WASP and CEQUAL- ICM) are more commonly used in wide and slower rivers, with higher lateral and/or vertical mixes rates. Besides, the more complex is the river studied more complex the model should be, which demands more costs and time for the model to be applied

An Optimal Control Framework for Resources Management in Agriculture

An optimal control framework to support the management and control of resources in a wide range of problems arising in agriculture is discussed. Lessons extracted from past research on the weed control problem and a survey of a vast body of pertinent literature led to the specification of key requirements to be met by a suitable optimization framework. The proposed layered control structure—including planning, coordination, and execution layers—relies on a set of nested optimization processes of which an “infinite horizon” Model Predictive Control scheme plays a key role in planning and coordination. Some challenges and recent results on the Pontryagin Maximum Principle for infinite horizon optimal control are also discussed.

A educação para os 'meios e os fins': a informação, o conhecimento e a comunicação na educação escolar básica e universitária

This research has as its main reference, the need to detect the development initiatives by public higher education, concepts, methods and teaching and pedagogical tools and to investigate the ability to transfer knowledge and practices of teaching and learning produced for other levels education. The task of providing appropriate training of teachers of basic education to university education is a vital political and administrative demands for a large country, which needs to adequately educate its people, so he can face in the right conditions, the huge and complex demands of regional and national development. The research presented here, aims to gauge the extent and adequacy of current media and information as tools for teaching and pedagogical transfer the knowledge and practices of teaching and learning as a tool for updating and also for training or non-presence blended Primary School Teacher Education. From the established goals will be carried out research, conceptual and field, to analyze and evaluate some educational practices and resulting forms of communication and also to assess the effects brought about by replacing the linear communication model and the model of unilateral to multilateral communication networks on digital models, and practices of schooling. The results obtained from both theoretical and practical will be on the selection of concepts, content production, methodologies and resources run by different "means" integrated with the cultural, economic and social development, both locally, regionally or nationally. The strategic aim will be to expand from the analysis, production and dissemination of concepts, methods and tools made by teachers of Basic Education and Higher Education, teaching and pedagogical possibilities of media and digital devices that are emerging as the derivation of network communication.
