This work proposes to adjust the Notification Oriented Paradigm (NOP) so that it provides support to fuzzy concepts. NOP is inspired by elements of imperative and declarative paradigms, seeking to solve some of the drawbacks of both. By decomposing an application into a network of smaller computational entities that are executed only when necessary, NOP eliminates the need to perform unnecessary computations and helps to achieve better logical-causal uncoupling, facilitating code reuse and application distribution over multiple processors or machines. In addition, NOP allows to express the logical-causal knowledge at a high level of abstraction, through rules in IF-THEN format. Fuzzy systems, in turn, perform logical inferences on causal knowledge bases (IF-THEN rules) that can deal with problems involving uncertainty. Since PON uses IF-THEN rules in an alternative way, reducing redundant evaluations and providing better decoupling, this research has been carried out to identify, propose and evaluate the necessary changes to be made on NOP allowing to be used in the development of fuzzy systems. After that, two fully usable materializations were created: a C++ framework, and a complete programming language (LingPONFuzzy) that provide support to fuzzy inference systems. From there study cases have been created and several tests cases were conducted, in order to validate the proposed solution. The test results have shown a significant reduction in the number of rules evaluated in comparison to a fuzzy system developed using conventional tools (frameworks), which could represent an improvement in performance of the applications.

O objetivo do trabalho foi avaliar o estoque de raízes finas (<2mm) com uma variabilidade espacial e distribuídas horizontalmente em três cultivos de palma de óleo (Elaeis guineensis), sendo dois em sistemas agroflorestais (SAF?s) e em um cultivo convencional. O estudo foi realizado no município de Tomé-Açu (PA), em área de agricultor familiar. As amostras foram coletadas entre 0 e 10 cm através de um trado com as dimensões de anel de 10 cm de profundidade e com um diâmetro de 5 cm, em diferentes locais e distâncias da planta. Os locais foram: entre saf?s, entre plantas e entre o carreador, e as distâncias foram: 0,6; 1,2; 2 e 4m. Em seguida, foram lavadas com água corrente sobre peneiras de 2 e 1 mm, nessa ordem, para retirada de partículas de solo e separadas nas classes de diâmetro: ≤2,0; 2,1-5,0 e 5,1-10,0. Depois foram secas em estufa (65 ºC, 48 h) e pesadas. Grande parte da biomassa de raízes, foi encontrada na primeira distância da planta, nas outras distâncias houve um decréscimo na biomassa de raízes, evidenciando uma distribuição horizontal decrescente.

Este trabalho busca apresentar uma discussão acerca da constituição do território brasileiro a partir de sua estrutura estatal federativa e organização política. Para tanto, a idéia de território usado (SANTOS, 1994, 1996; SANTOS; SILVEIRA, 2001) se apresenta como instrumento analítico de suma relevância. Conforme Santos e Silveira (2001, p. 20) o “que interessa discutir é, então, o território usado, sinônimo de espaço geográfico. Essa categoria, território usado, aponta para necessidade de um esforço destinado a analisar sistematicamente a constituição do território. Como se trata de uma proposta totalmente empiricizável, segue-se daí o enriquecimento da teoria”. Entender o território usado implica entender que existe um conjunto de ações – ou seja, um evento – que dinamizam este território e que, quando dinamizado, este mesmo território retorna como um condicionante das ações sociais. Seguindo pelo mesmo partido de método proposto por Santos (1996), entendemos aqui território usado como conjunto indissociável de sistema de objetos (materialidades) e de sistemas de ações (eventos). A federação no Brasil pode ser tratada, teoricamente, como um evento, isto é, a instituição da federação foi um conjunto de acontecimentos que atingiram e transformaram o território e, a partir desse momento esse mesmo território se tornou uma norma para a vigência dessa federação. No país, os mecanismos de distribuição e de redistribuição de recursos entre os entes federados adquirem grande importância pelo fato de serem eles os elementos que permitem uma maior ou menor autonomia na administração pública. Parcelas do território recebem mais recursos do que outras proporcionando, assim, uma difusão seletiva do meio técnico-científico-informacional (SANTOS, 1996) pelo território.

Os sistemas de saúde em todo o mundo estão em constante processo de construção e desenvolvimento, a fim de prover um melhor estado de saúde para as suas populações. Consequentemente, os sistemas não são estáticos, pois devem acompanhar as necessidades e mudanças sociais e culturais que acompanham o desenvolvimento de qualquer sociedade. A partir desta premissa, a unidade aborda o conceito de atenção à saúde e sua amplitude para o cuidado das populações; bem como a definição de promoção da saúde desde os primórdios do conceito até a definição contemporânea para concluir com a discussão acerca da atenção primária da saúde como um importante nível do sistema que possibilita a organização da atenção e propõe-se a um alto grau de resolubilidade das necessidades de saúde da população.

Tópico 1 – Sistemas de Informação em Saúde O tópico informa a disponibilidade, no Brasil, de diversos SIS, definidos pela OMS como conjuntos de componentes que atuam de forma integrada utilizando a informação para o planejamento, organização, operação e avaliação dos serviços de saúde, sendo demonstrado o quanto as modernas tecnologias digitais contribuem para a velocidade de aquisição e distribuição de dados, repercutindo positivamente no trabalho de ESF/NASF e, de um modo geral nas políticas de saúde pública. São mostrados, também, os diversos modelos de gestão da informação, sendo o modelo federalista considerado o mais eficiente. Finalmente, é proposta uma reflexão a cerca da importância da coleta de dados minuciosa, eficiente e consciente por parte dos profissionais de saúde, para que as ações possam se planejadas adequadamente, de moda a atender as reais necessidades da comunidade.

This study focus on the reconfiguration of educational management in Argentina, Brazil, Chile and Mexico, which was promoted by the new logic of social regulation and the new role attributed to the State, considering each country's own historicity. So, the cultural factors that interfere on the dynamics of the 90' school reform are analyzed. Aspects that show the homogeneity or heterogeneity of these reforms in the region, as well as local specificities that block out the concretization of the reform are underlined. It is shown that the historicity that characterizes the educational reform has taken, in each country, a form that can be called, in Mexico, conservative rupture; in Chile, conservative continuity; in Brazil, conservative renovation; and, in Argentina, interrupted rupture. Some conclusions about the impact of educational reform in the selected countries are recuperated through the analysis of 186 academic texts on the subject.

By the year 2005 the world biochemical market will reach an estimated $ 100 billion and separation processes are a vital link between lab discoveries and the fulfillment of this commercialization potential. The practical application of aqueous two-phase systems (ATPS) to extraction processes has been exploited for several years for the recovery of biological products. Unfortunately, this has not resulted in an extensive presence of the technique in commercial processes. In this paper a critical overview of the fundamental thermodynamic properties related to formation of aqueous two-phase systems and their application to extraction and purification of bioparticules is presented.

One of the main referring subjects to the solar energy is how to compare it economically with other sources of energy, as much alternatives as with conventionals (like the electric grid). The purpose of this work was to develop a software which congregates the technical and economic main data to identify, through methods of microeconomic analysis, the commercial viability in the sizing of photovoltaic systems, besides considering the benefits proceeding from the proper energy generation. Considering the period of useful life of the components of the generation system of photovoltaic electricity, the costs of the energy proceeding from the conventional grid had been identified. For the comparison of the conventional sources, electric grid and diesel generation, three scenes of costs of photovoltaic panels and two for the factor of availability of diesel generation had been used. The results have shown that if the cost of the panels is low and the place of installation is more distant of the electric grid, the photovoltaic system becomes the best option.

A trial was carried out to evaluate the chemical composition in the aerial part of lettuce, cv. 'Elisa', irrigated with wastewater treated with constructed wetland and source deposit water, grown on a Rhodic Hapludox Soil, using the irrigation systems sprinkle, subsurface drip and surface drip irrigation. The experiment was carried out from August 17th to October 3rd of 2001 and the chemical analyses of the lettuce were accomplished to 47 days after transplanting of the seedling. The aerial part of the lettuce was analyzed as for the levels of total nitrogen, nitrate, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, sodium, boron, cobalt and molybdenum. The sodium and the sulfur presented higher levels than the maximum suitable in the aerial part of the lettuce and the smallest level of magnesium, while other chemical elements analyzed were normal and appropriate considering the standard for well-nourished plants, not being influenced by the water type. The sodium was the chemical element that presented the highest levels in the aerial part of the lettuce in the treatments irrigated with wastewater, presenting significant difference in relationship to the treatments irrigated with source deposit water in the three irrigation systems. The use of the different irrigation systems by the application of wastewater treated with constructed wetland did not interfere in the levels of nutrients in the aerial part of the lettuce.

As a way to reduce water losses in furrow irrigation systems, used in fresh market tomato production, farmers are improperly distributing water into the field using plastic hose. The objective of this work was to study the suitability of using quick coupler sprinkler as hose connectors for water distribution in tomato plantation. The first step of the study was to assess the current hose field operation for tomato growers. Subsequently, four models of quick couplers sprinklers available in the market were tested in laboratory to determine the coefficient of resistance, the equivalent tube length, the head loss curve and the linking efficiency. As result, a structural design for hose connectors was presented using the model of coupling with the best hydraulic performance. Additionally, some technical recommendations on its use in irrigation water distribution are highlighted. Despite the requirement for additional field trials, the proposed system has potential to optimize the water use efficiency, to improve workers ergonomic conditions, and ensure good profitability to the producer.

Gender-related differences in gastric emptying are still controversial. The aims of this study were: to confirm the sex-related difference in gastric emptying of a solid meal and to investigate its association with different patterns of meal distribution between the proximal and distal gastric compartments. Eighteen healthy volunteers (nine males, mean age 35 ± 9 years; nine females, mean age: 41 ± 11 years) were studied in the morning, after ingestion of the solid test-meal (an omelette labeled with 185MBq of 99mTc-sulfur colloid). Simultaneous anterior and posterior images of the stomach were acquired immediately after ingestion of the meal and every 10 minutes for 120 minutes. Time versus activity curves were obtained for the whole, proximal and distal stomach. Gastric T½ was longer in women (96.1 ± 17.2 min) than in men (79.9 ± 17.8 min; P = 0.02). The analysis of the meal distribution inside the stomach showed no differences between males and females in proximal gastric emptying, but the meal retention in the distal compartment was significantly increased among women (P = 0.04). In conclusion, gastric emptying of a solid meal is slower in pre-menopausal women than in age-matched men, probably due to an increased retention of the meal in the distal compartment. This should be taken into consideration to avoid misleading diagnosis of gastroparesis for female patients.
