Correction of soil acidity in the subsurface of an oxisol with sandy loam texture under no-tillage

No Rio Grande do Sul (RS), muitas áreas sob plantio direto apresentam elevada saturação por Al e baixa saturação por bases na camada de 0,10-0,20 m (subsuperfície), e isso pode diminuir a produção de grãos de culturas anuais. O objetivo do presente trabalho foi avaliar se a ocorrência de alta saturação por Al e baixa saturação por bases em subsuperfície (0,10-0,20 m), no plantio direto, pode representar um ambiente restritivo para a produção de culturas, bem como avaliar os modos de incorporação de calcário na correção da acidez do solo em subsuperfície. Para isso, foi realizado um experimento com os cultivos de soja (2005/ 2006), milho (2006/2007), trigo (2007) e soja (2007/2008), em um Latossolo Vermelho distrófico típico (Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 2006) de textura franco arenosa, há quatro anos sob plantio direto, no município de Tupanciretã (RS). Os seis tratamentos foram: sem revolvimento com ou sem calcário; lavração com ou sem calcário; e escarificação com ou sem calcário. Aos 24 meses após a aplicação dos tratamentos e nas camadas de 0-0,05, 0,05-0,10, 0,10-0,15, 0,15-0,20 e 0,20-0,30 m, foram avaliados os valores de pH-H2O, saturação por Al e por bases. Avaliou-se a produtividade de soja (2005/2006), milho (2006/2007), trigo (2007) e soja (2007/2008). A acidez do solo em subsuperfície não alterou a produtividade das culturas quando as propriedades de acidez na camada de 0-0,10 m estavam em níveis em que não se recomenda a aplicação de calcário, segundo a CQFSRS/SC (2004). A incorporação de calcário com aração foi o modo mais eficiente de corrigir a acidez em profundidade.

Pattern recognition structured heuristics methods for image processing in mobile robot navigation

In this project, the main focus is to apply image processing techniques in computer vision through an omnidirectional vision system to agricultural mobile robots (AMR) used for trajectory navigation problems, as well as localization matters. To carry through this task, computational methods based on the JSEG algorithm were used to provide the classification and the characterization of such problems, together with Artificial Neural Networks (ANN) for pattern recognition. Therefore, it was possible to run simulations and carry out analyses of the performance of JSEG image segmentation technique through Matlab/Octave platforms, along with the application of customized Back-propagation algorithm and statistical methods as structured heuristics methods in a Simulink environment. Having the aforementioned procedures been done, it was practicable to classify and also characterize the HSV space color segments, not to mention allow the recognition of patterns in which reasonably accurate results were obtained. ©2010 IEEE.

Distributed generators as providers of reactive power support - A market approach

Traditionally, ancillary services are supplied by large conventional generators. However, with the huge penetration of distributed generators (DGs) as a result of the growing interest in satisfying energy requirements, and considering the benefits that they can bring along to the electrical system and to the environment, it appears reasonable to assume that ancillary services could also be provided by DGs in an economical and efficient way. In this paper, a settlement procedure for a reactive power market for DGs in distribution systems is proposed. Attention is directed to wind turbines connected to the network through synchronous generators with permanent magnets and doubly-fed induction generators. The generation uncertainty of this kind of DG is reduced by running a multi-objective optimization algorithm in multiple probabilistic scenarios through the Monte Carlo method and by representing the active power generated by the DGs through Markov models. The objectives to be minimized are the payments of the distribution system operator to the DGs for reactive power, the curtailment of transactions committed in an active power market previously settled, the losses in the lines of the network, and a voltage profile index. The proposed methodology was tested using a modified IEEE 37-bus distribution test system. © 1969-2012 IEEE.

A implantação da televisão digital terrestre na Espanha

This monograph has as objectives introduce digital terrestrial television, describing the process of installation of this in Spain, their technical qualities and possibilities of change and innovation that this creates. The exposure of the different chapters of this monograph has a objective presenting and discussing what are the characteristics of this new technology, your birth, what is its importance in communication and how this is inserted inside the Spanish reality. The introduction of digital terrestrial television in Spain is cited as an example of a pioneer in the development and installation of this new technology, but also appears as a nation that has come a way with some economic failures, reaching one of the largest cases of delayed installation of digital television in Western Europe. Making use of the European system for digital terrestrial television (DVB-T - Digital Video Broadcasting) it was possible some advances as the quality of communication and strengthening national public television system, but many vices of analog system were transferred this new system, as the concentration of channels to a foreign group and interactivity opportunities were wasted. Digital terrestrial television can provides better picture quality and sound, possibility of interactivity, mobility, hypermedia and multiprogramming, while the latter tool may lead to the democratization of media, opening it to other social agents. Going much further than just a technological advancement, digital television is strongly connected with the politics and the economy of the nation in which it operates

A importância da linguagem do educador no processo de construção da autonomia moral da criança pré-escolar

This paper demonstrates that in every society there are limits and these are imposed on its members. However, the awareness and the determination of theses limits are necessarily how they are transmitted by the educator to the learners. Its purpose is to show that autonomous, critical and cooperative individuals are result of the form they were educated and instructed in the classroom. Schools and educators should be concerned with the education of individuals able to reflect, discuss and solve the social and moral conflicts through dialogue, exposition of ideas, suggesting alternatives and the preparation and reworking of the principles and norms that govern society. The goal of this study is identify and highlight the importance of educator language in conflict resolution, its consequences and effects on the process of building the moral autonomy of children in preschool, as well as discussing, in theory the two types of language, evaluative and descriptive. In the same way, show the importance of descriptive language on the construction process from moral autonomy of learner. Several existing research about the chosen subject led to face this challenge, deepening the study to show that and educational system focused on cooperative environment, where teacher actions encourage social interaction, giving the student opportunity to talk, argue and present his thoughts, causes a significant development toward the construction of moral autonomy on the learner
