Tratabilidade de águas pluviais utilizando coagulante natural a base de tanino visando fins não potáveis

This paper aimed to study the treatability of rainwater using natural coagulant tannin based. Assays were performed in laboratory scale and aimed to study the conditions most suitable for dosage and for pH of coagulation. Preliminary tests indicated that tannin concentration of 3% (m/m) prepared from the commercial solution presented the best set of results (84.3% of removal for apparent color and 82.51% for turbidity) compared to ferric chloride (66.25% of removal for apparent color and 67.82% for turbidity) and starch (73.68% of removal for apparent color and 67.19% for turbidity). The coagulation diagrams indicate that the best region for dosage ranges from 15 mg/L to about 37.5 mg/L and for pH ranging from about 6.5 to 7.5. The results indicate that the tannin based natural coagulant may be an alternative to conventional coagulants for rainwater treatment seeking non potable uses.

Análise da viabilidade do uso de biogás gerado a partir de dejetos bovinos em microturbinas para fins de geração, cogeração e trigeração de energia

The use of digesters has become an important alternative for the proper disposal of organic agricultural wastes, serving as a solution to some environmental and health problems. Furthermore, the process of digestion provides commercially valuable by products such as biogas and bio fertilizer. The generation of biogas from agricultural waste, and its use in power generation systems has aroused great interest in rural areas because it enables supply in whole or in large part the energy demand of ownership by reducing production costs. The advent of technology has brought new forms of energy conversion of biogas, as the use of micro turbines specifies to be fuelled with biogas derived from the decomposition of organic matter in digesters, since it has a low level of methane in its composition, and high degree of impurities such as hydrogen sulphide, which are harmful to equipment and reduce the calorific value of biogas. The use of micro turbines behind other advantages like low emissions, great fuel flexibility and low maintenance. This paper presents an analysis of the feasibility of using biogas generated from cattle manure in micro turbines to generate electricity. Behind also an assessment of the energy potential that each animal has on various uses of biogas, and forms of energy recovery from the exhaust gases of the micro turbine. Also conducts an evaluation of the energy savings that the use of biogas aggregates properties.

Reino da natureza, reino dos fins, e proto-reino: um estudo de traduções conservativas

We provide conservative translations from propositional modal logic KT (the simplest normal alethic logic) into propositional modal logic KD (the simplest normal deontic logic), and from this into the propositional modal logic K (the simplest normal logic simpliciter). Following an idea discussed by Jaakko Hintikka, these conservative translations are based on the third formulation of Kantian categorical imperative, the formulation of the Kingdom of Ends.

Auto-organização, complexidade e formação da consciência bioética

This article introduces the concepts of self-organization and autonomy as presented by the thought of Michel Debrun and Edgar Morin and their relationship to the development of a bioethical conscience by means of the school educational process. The proposal aims to contribute to the development of autonomy of students and thus be conducive to their self-organization as “responsible ethical subjects”.

Geotecnologia aplicada no estudo e planejamento de ocupação e uso do solo em uma bacia hidrográfica para fins agrícolas e conservacionistas

The study aimed to obtain the land use of the watershed Ribeirão Santo Antonio - São Manuel (SP), through the thematic map of the satellite image. The cartographic databases were planialtimetric letter in digital format used in georeferencing and the satellite image. Geographic Information Systems (GIS) -IDRISI Andes 15.0 was use to perform the image georeferencing and to do the thematic map obtained from the visual interpretation the satellite image. The map of land use showed that the culture of sugar cane occupies most of the area (81.00%), when analyzing the satellite image. This result show us the predominance of agricultural occupation in the region. The thematic map obtained by the classification screen, using GIS, allowed the mapping of land use, generating data that will assist in future planning area recovery. The results of the study showed the efficiency, speed and reliability of the tools used, these being very useful for future projects.
