Modern science has no basis of positivist epistemological and methodological foundations sufficient for building a comprehensive understanding of the world of man and society. A study of contrasts to the paradigms of science, technology and modern rationality expressed the thoughts of Jürgen Habermas, Herbert Marcuse, Martin Heidegger, Theodor Adorno, Max Horkheimer, and Boaventura Santos Souza was conducted. We used a dialectic approach to highlight the contradictions and limitations of this paradigm and highlight other paradigms of positivist epistemological basis not carry that enabled the overcoming of knowledge as regulation by knowledge empowerment. It was evident, based on the theories of these authors and arguments of researchers such as Albert Einstein, Ilya Prigogine, Michel Foucault, among others, that modern science has methodological limitations Cartesian basis and fragile epistemological basis when trying to conceive man, world and society while dynamically articulated.

In the electromagnetic field work out, due to indirect lightning discharge, the consumption of computational resources is essentially in the numerical integration of the Maxwell equations. These equations are solved in each discretized point for each time step because the work out of the field involves the inverse of the distance that’s powered by 2, 3, 4 and 5; additiona lly its depends on the wave incident angle, which varies point by point, so it is impossible to interpolate, in a traditional way, intermediate data to optimize the calculus. It is proposed here the implementation of a parabolic space interpolation to reduce the computational needed resources; the compromise is the electromagnetic field calculation in the minimum time limiting the error to 0.2%. It is looking for the optimum points, methodologically, to implement this interpolation by checking the results against the obtained ones without the omission of any point, so it is considered that this strategy is a good option in the electromagnetic field optimum calculation

Concrete's consumption increases all over the world with each passing day, and that has led to the development of new materials such as structural lightweight concrete SLC. The advantages of using this material is that since it is light, there is not so much need to spend a lot of income with structure foundations, transport and even lifting of precast concrete units. To obtain SLC the use of some light aggregate is needed, like exfoliated vermiculite. It is known that if concrete's self-weight is reduced, its mechanic resistance is also reduced. The present work was to analyze the influence of the addition of vermiculite in different amounts on a high performance concrete mix, observing if with the addition it would be possible to obtain high performance lightweight concrete. The experimental analysis included the study of compressive strength, diametric compression traction, efficiency factor and specific mass in the hardened state. Two specimens were molded and tested at ages of 7 and 28 days.

Oil refineries are one of the industries most important to the functioning of the country that generate end products from oil received from production fields. The different locations in the refinery where occur the refining processes are the process units, also called refining or processing units. Each of these units comprises a set of equipment responsible for a refining step. The hydrotreating catalyst is a hydrogenation process which is currently operated at the refineries with a performance degradation of about 90% of compounds of sulfur, nitrogen and oxygen from the liquid fractions of petroleum distillates. Refinery pressure vessels are not only the most important features of most process industries, as well as usually the larger items, weight and unit costs, representing on average 60% of the total cost of materials and unit equipment process. This paper aims to describe the procedures for correct analysis and selection of materials to be used in pressure vessels, which meets with security service conditions within a unit at the refinery, taking into account the mechanical properties of materials, corrosion resistance, welding, obtaining facilities manufacturing and the expected useful life, based on the ASME code, the PETROBRAS and ASTM standards.

Water scarcity is increasingly haunting the world, and the outlook for the next few years is not enough for everyone to drink, thanks to the pollution and waste that grows every year for a population growing more and more on the globe. Water scarcity is not the only problem we face. In Brazil, the country with the largest freshwater reserve in the world, another major problem is the supply of water in the cities, in several regions the population faces an inefficient supply system, which presents faults in the water course the residence. The present work proposes an improvement in the residential water supply system that uses hydraulic pumps, automating the process of feeding the reservoirs of the residential, developing an autonomous system allowing the user to have control of the supply process in their property. The importance of the work is made by the difficulty encountered by residents of regions that suffer from the irregular water supply in their homes. The work was based on an experimental research, starting from a bibliographical research in several literatures as academic papers, researches and articles, focused on the study on water supply, hydraulic systems and automation. The studies were based on a residence in the northern part of Manaus/Amazonas, where there are irregularities in the water supply in this region, causing residents to use hydraulic systems to supply their residential reservoirs. In addition, a prototype for better observation of the automated operation of the small-scale supply process was developed for the study to perform better. Through an existing hydraulic system in the house, the automation process was carried out by the elaboration of an electrical system with the function of activating the pump through an Arduino® and for indicate the sensors responsible for the level of water in the reservoirs. A simple and practical monitoring system was developed based on an electrical principle and a hydraulic system. After the tests carried out, the model proposed in this work showed a simple and functional hydraulic supply system, facilitating for the user the monitoring of the water supply operation for the residence, the project was elaborated using elements already existing in the residence in order to reduce costs for the user, an autonomous system was implanted in the water supply process of the residence, thus enabling practicality in the activation of the hydraulic pump and the monitoring of levels in the reservoirs of the residence.

El transformador de potencia es uno de los elementos más costosos del sistema de potencia, siendo generalmente muy confiable, con una vida útil de 20 a 35 años, que puede extenderse hasta unos 60 años con un mantenimiento apropiado [1]. Actualmente un alto porcentaje de los transformadores instalados en los sistemas eléctricos, se encuentra en una etapa de envejecimiento avanzada, por lo que se hace necesario conocer su condición a través de pruebas de diagnostico y programas de mantenimiento, para detectar situaciones de riesgo o de limitación de uso, que podrían llevar a tomar acciones para prevenir la ocurrencia de fallas graves, con las consiguientes interrupciones del servicio, o programar acciones que permitan prolongar la vida del transformador (tales como secados). Uno de los elementos que determinan la vida útil remanente del transformador es su aislamiento, el cual se divide en aislamiento líquido (generalmente aceite) y aislamiento solido (papel). Durante su funcionamiento, los transformadores están sometidos a condiciones que deterioran su aislamiento, las cuales se originan generalmente por alta temperatura y presencia humedad, que combinadas con esfuerzos eléctricos y mecánicos aceleran el proceso de degradación. La degradación del aislamiento es por lo tanto una preocupación muy importante para las empresas que operan los transformadores. En años recientes han aparecido nuevos métodos de diagnostico, que basados en los cambios de la respuesta dieléctrica del aislamiento permiten estimar de manera indirecta su contenido de humedad y brindan información de la degradación de sus componentes.
