O objetivo deste trabalho foi avaliar o pH e a densidade óptica das soluções de azul de metileno a 1% e 2% (tamponadas e não tamponadas) após a imersão de três cimentos endodônticos. Foram preparados oitenta espécimes de cada cimento endodôntico (Endofill, AH Plus e Sealapex), os quais foram imersos nas soluções corantes. As soluções foram analisadas antes e após a imersão dos materiais nos períodos de tempo de 0, 24, 48 e 72h. Foram realizadas avaliações do pH utilizando um pHmetro e da densidade óptica utilizando um espectofotômetro ajustado em 596nm. Os dados de pH foram analisados através de estatística descritiva e os dados da densidade óptica foram analisados pela ANOVA e teste de Tukey 5%. Pôde-se verificar que as soluções corantes de azul de metileno tamponadas e não tamponadas apresentaram pequena variação nos valores de pH e densidade óptica antes do contato com os cimentos endodônticos. As soluções corantes não tamponadas apresentaram valores de pH menores que as tamponadas, independentemente do contato com qualquer cimento endodôntico. Os cimentos endodônticos promoveram alterações nos valores de pH das soluções corantes, sendo que as maiores alterações ocorreram nas soluções não tamponadas. Ocorreram alterações nos valores da densidade óptica das soluções corantes tamponadas e não tamponadas nos diferentes períodos de tempo de análise, sendo diferentes para cada cimento endodôntico utilizado

A Política Educacional de Inclusão constituiu-se no objeto de investigação, tendo como recorte histórico os marcos legais e as ações desencadeadas pelo poder público, que visavam garantir aos portadores de necessidades especais o direito constitucional à educação, a partir dos anos 1990. A Constituição Federal de 1988 assevera o atendimento educacional especializado aos portadores de deficiência, preferencialmente na rede regular de ensino (art. 208, III) e, posteriormente, a LDBEN 9.394/96, por meio do art. 3o, inciso I e do art. 4 o inciso III e do CAPÍTULO V Da Educação Especial (com três artigos) ratificou e disciplinou os dispositivos constitucionais. Além desses documentos basilares, foram editadas outras medidas legais com o objetivo de disciplinar a questão, além de programas e ações propostas pela Secretaria de Educação Continuada, Alfabetização, Diversidade e Inclusão (SECADI), que substituiu, a partir de 2004, a Secretaria de Educação Especial (SEESP). Os sistemas de ensino, em âmbito estadual e municipal, também procuraram disciplinar a questão da inclusão na rede regular de ensino dos portadores de necessidades educacionais especiais. Partindo dessa constatação inicial, uma questão passou a nortear o trabalho: quais as medidas, ações e programas desencadeados pelo poder público municipal para o cumprimento dos preceitos expressos na CF/88, na LDBEN 9.394/96 e na legislação correlata? O objetivo geral desta pesquisa foi analisar as atuais políticas públicas de inclusão dos alunos com necessidades especiais na rede regular de ensino, verificando junto ao sistema municipal de educação de Rio Claro/SP quais medidas, ações e programas que foram desencadeados a partir da década de 1990. Tratou-se de uma pesquisa de cunho qualitativo, realizada por meio de revisão bibliográfica, análise documental e entrevista semiestruturada... (Resumo completo, clicar acesso eletrônico abaixo)

The non existence of sewage services creates an unhealthy environmental, causing impact extremely prejudicial to the human health. In Brazil, this item represents the biggest deficit in the basic sanitation these days, and only about 50% of the population is attended. The sewage collection network is a needful system for the basic sanitation. Between the parameters of the project of a system of collection and sewage transportation, the definition of the population that will be attended is one of the most important variables, and that should be done based on criterion of population growth and in accordant to directrix presents in the comprehensive city plan. In this paper, were evaluated methods of growth based on the geometric growth rate, on the population density and on the number of residents per dwelling, and also mathematics models of growth prediction, emphasizing in the geometric growth and on the logistic curve method. That way, the goal of this paper were value the hydraulic performance in one of the watersheds delimited by the sewage network magnification work existent in the city of Cacoal–RO. Using simulation with different scenarios, the results pointed that the hydraulic performance of the system were strongly affected by the population determination method used. For the same drained area the diameters range from 150 to 250 mm as well as the trench’s deep, where some stretches exceeded the maximum values contained in the standard. Besides, the variation of the sewage contribution rate due the population variation estimated in different scenarios, led to alterations in others important project parameters, such as slope, shallow pool, tensile stress and spreading velocity

Synchronization in nonlinear dynamical systems, especially in chaotic systems, is field of research in several areas of knowledge, such as Mechanical Engineering and Electrical Engineering, Biology, Physics, among others. In simple terms, two systems are synchronized if after a certain time, they have similar behavior or occurring at the same time. The sound and image in a film is an example of this phenomenon in our daily lives. The studies of synchronization include studies of continuous dynamic systems, governed by differential equations or studies of discrete time dynamical systems, also called maps. Maps correspond, in general, discretizations of differential equations and are widely used to model physical systems, mainly due to its ease of computational. It is enough to make iterations from given initial conditions for knowing the trajectories of system. This completion of course work based on the study of the map called ”Zaslavksy Web Map”. The Zaslavksy Web Map is a result of the combination of the movements of a particle in a constant magnetic field and a wave electrostatic propagating perpendicular to the magnetic field. Apart from interest in the particularities of this map, there was objective the deepening of concepts of nonlinear dynamics, as equilibrium points, linear stability, stability non-linear, bifurcation and chaos

The discovering process of new morbid genes and new target proteins for drugs have been shown to be very costly and laborious. Having in view cutting costs and speeding up this process, we propose, in this work, a new method to determine the gene druggability score and morbidity score, the probabilities of the protein encoded by the gene have the characteristics that make it a new target for drugs and in case of an alteration in that gene, we observed a phenotype that characterizes a genetic based illness. To determine these characteristics, we built, analyzed and determined the characteristics of the topology of the integrated molecular interactions network among human genes containing physical interactions between proteins, metabolic interactions and interactions of transcriptional regulation, and included other data such as level of gene transcription and cellular localization of the protein encoded by the gene. We tested our model in training sets and achieved results equal or better than the ones achieved by similar methods in the literature. Finally, with the purpose of investigating whether the assigned scores resembles the potential druggabilities and morbities of the previously unclassi ed genes, we looked for evidences in biomedical literature supporting the potential druggability and morbidity status of genes with the 10 highest scores. We found clear evidences for 73% and 90% of potential druggable and morbid genes respectively
