Simulação computacional da extração líquido-líquido fracionada de enzimas para produção de biodiesel

Liquid-liquid extraction is utilized for purification of biomolecules by Aqueous Biphasic Systems (ABS), since this process does not damage the biotechnological potential of these compounds. In this work, using the free software Scilab®, the fractionated liquid-liquid extraction was studied aiming a lipase (target enzyme) partition in a water + PEG + DEX system. Lisozime was considered as contaminant. As computer simulations has been extensively used when a first estimation of technical feasibility of process is desired, this work demonstred that the system is viable for recovery the 80 % till 90 % the target enzyme, but should be noted that the trial aimed only the fractionation of the enzyme target of a contaminant, not its concentration, which should be done by another process.

Biblioteca de escalonamento de tarefas em grid computacional - LIBTS

The use of computational grid simulators is particularly important for studying the algorithms of task scheduling. Through the simulators it’s possible to assess and compare the performance of different algorithms in various scenarios. Despite the simulation tools provide basic features for simulation in distributed environments, they don’t offer internal policies of task scheduling, so that the implementation of the algorithms must be realized by the user himself. Therefore, this study aims to present the library of task scheduling LIBTS (LIBrary Tasks Scheduling) which is developed and adapted to the SimGrid simulator to provide the users with a tool to analyze the algorithms of task scheduling in the computational grid.

Modelagem computacional das túnicas cardíacas para processamento e controle de qualidade

This paper considers a study of the anatomical features of the cardiac system and a three-dimensional model of the different tunics that comprise the heart wall, for processing and quality control of radiological images. The structures are built by the layer overlapping method, where a layer can be understood as a slice of the three-dimensional object. The pericardium, myocardium and endocardium were represented with three-dimensional cylinders and hexagons. The spatial arrangement of the cardiac system is determined by an background image of a real model, which values are defined according to the shape of the region and on the anatomical patients characteristics. The results are significant, considering the anatomical structures details, as well as the representation of the thicknesses of the regions of the heart wall. The validation of the anatomical model was accomplished through comparisons with dimensions obtained from a real model and allows verifying that the model is appropriate. The degree of representation will allow the verification of the influence of radiological parameters, morphometric peculiarities and stage of the diseases on the quality of the images, as well as on the performance of the Computer-Aided Diagnosis (CAD).

Aplicação de programa computacional no dimensionamento de volume de reservatório para sistema de aproveitamento de água pluvial da cidade de Ponta Grossa, PR

The main aim of this paper was to use the REZZ software to calculate the tank volume rainwater harvesting system. For this purpose, rain data of Ponta Grossa-PR-Brazil were used considering different statistical treatment (average, 75%, 85%, 95% and 99% of confidence) and different roof areas (50, 80, 120 and 200 m2). The harvesting system was considered only for toilet flush in households with 3, 4 and 5 inhabitants. There were applied the following methods/concepts: Flow equalization (Rippl); Brazilian method as well the English and German practical methods. Further, the mass-balance was simulated for some conditions. All considered methods are described in NBR15527/07, the Brazilian standard for rainwater harvesting. As expected, the results pointed out for huge differences depending on the choice method and the statistical treatment of the rain data. The REZZ appliance showed to be useful thus permitting to set different conditions and to obtain rapid results in order to assist designers to adopt the best cistern volume for each particular case.

Estudo de caso: do desenvolvimento a aplicação de um jogo computacional para o ensino da tabela periódica

The chemistry is a science little adored by students, because it is a modeling science. The study in chemistry needs a little of abstraction to be able to view something that can not being viewed, that is why chemistry uses many models and tools. The periodic table is a tool useful, but complicated to be understood, where many students end up just decorating for a test, and losing interest in class. The use of ludic games is a way to facilitate the teaching-learning process, because a game has rules to be followed, so the student will get involved to the content to be studied in addition to having to respect rules. Therefore, it is needed that teachers make their lectures more attractive for their students. This work has analyzed an alternative method for teaching the periodic table using basic computer resources, in order to propose a ludic game to a different class, seeking to get the students attention in order to facilitate the understanding of the content
