The objective of this paper is to introduce a model, called the Model of the System of Schemes of Actions and Operations on Symbols and Signs (MoSSAOSS), that articulates a systemic, systematic, and synthetic view of some of the principal theoretic and experimental results obtained by Piaget and his coworkers. Here, the term model means a schematic representation of experience, the relation of whose elements can be explored by means of logic and mathematics in order to deduce properties that correspond, in a sufficiently accurate form, to direct observable empirical properties. The MoSSAOSS model is intended to reveal in an abstract and simplified form, and through explicit hypothesis and definitions, the general structure and function of the System of Schemes of Actions and Operations on Symbols and Signs. It is this system that furnishes the elements that make possible the diverse structures necessary for the knowledge of the epistemic subject, the subject of knowledge, the stages in their construction, and the attribution of significations to objects, to situations, and to the actions and operations of the subject itself.

This study aimed to analyze the characteristics of temperature and air humidity from neighborhoods of Presidente Prudente according to the pattern of land use specific to each of them, over a representative period of winter (July 2011), at different times of day in order to identify the major changes in climatic elements and their causes in urban areas. The work is based mainly on the Monteiro’s theory (1976) of Urban Climate System and for its implementation was used data of temperature and relative humidity of the air in three urban neighborhoods and one rural area. With them, a Chart of Rhythmic Analysis was elaborated for identification of the operating atmospherics systems and basic climate conditions in the period. Were prepared, also, graphs and charts to evaluate and compare the data. There were significant differences in the characteristics of temperature and air humidity between the neighborhoods, especially when compared the urban areas with the rural area

The term refrigeration solar refers to any air conditioning system that uses solar energy as a primary energy source. The use of solar radiation for cooling purposes is divided according to their technological possibilities which are distinguished from one another as the way that energy is involved in the cycle, work or heat. The first case is related to vapor compression cycles, in which the work input is provided by the photovoltaic conversion of solar energy into electrical energy. In the second case, an absorption refrigeration cycle is used and the thermal energy collected from the solar radiation is provided at the generator of this cycle.. In this work a system with an absorption cycle using the pair BrLi-water, using solar energy as input is modeled. It is considered a simple refrigeration cycle whose the equations of mass and energy conservation in each component are developed in order to obtain an algebraic equation set and a simulation routine using the EES software. Although the simulation operates under certain specified thermal load it is possible to estimate the necessary areas of heat exchangers and solar collectors

Pentraxina 3 (PTX3) é um componente essencial da resposta imune inata e age como receptores de reconhecimento de padrões (PPRs) reconhecendo produtos microbianos, opsonizando fungos, bactérias Gram positivas e negativas, além de apresentar a capacidade de ativar o sistema complemento. Poucos estudos na literatura mundial têm investigado a expressão de PTX3 nas complicações gestacionais associadas à invasão microbiana da cavidade amniótica e resultados conflitantes têm sido descritos. Avaliar a expressão gênica e protéica de PTX3 em membranas corioamnióticas de gestações pré-termo complicadas por Trabalho de Parto Prematuro (TPP) e bolsa íntegra ou Rotura Prematura de Membranas Pré-Termo (RPM-PT), na presença de corioamnionite histológica (CA). Foram incluídas no estudo 30 gestantes com TPP, sendo 15 na ausência e 15 na presença de corioamnionite histológica e 30 gestantes com RPM-PT, sendo 15 na ausência e 15 na presença de corioamnionite histológica. Cortes parafinizados foram encaminhados à análise histopatológica para confirmação de corioamnionite histológica. Outros fragmentos de 1cm2 das membranas foram submetidos à extração de RNA total. Após a extração do RNA, as amostras com concentração entre 0,02 e 0,2g/ L de RNA foram submetidas à obtenção de cDNA para posterior utilização na quantificação da expressão gênica de PTX3 pela técnica da PCR em tempo real empregando-se o Sistema TaqMan® Gene Expression Assays. Fragmentos das mesmas amostras incluídas no estudo foram utilizados para verificar a expressão da proteína PTX-3 através da técnica de Western Blotting. Dentre as 60 membranas corioamnióticas incluídas no estudo, 56 (93,3%) expressaram PTX-3. Não houve diferença estatisticamente significativa na expressão de mRNA de PTX-3 (p=0,137) entre os grupos: RPM-PT na presença de CA (Md: 0.355; 0.11-1.03), RPM-PT na...(Resumo completo, clicar acesso eletrônico abaixo)

The term model refers to any representation of a real system. The use of models in Hydrogeology can be valuable predictive tools for management of groundwater resources. The numeric models of groundwater flow, object of this study, consist on a set of differential equations that describe the water flow in the porous medium. In this context, numeric simulations were made for a sub-basin located at Cara Preta farm – Santa Rita do Passa Quatro – SP. The aquifer at the local is composed by rocks of Pirambóia Formation, which is part of Guarani Aquifer System. It was developed a conceptual model from previous studies in the area, and from that, simulations were made through the software Visual Modflow®. The conceptual model established previously was considered consistent through the results of simulation.
