Nowadays several nursing courses are seeking innovative pedagogical alternatives that can consolidate an education which is more coherent with the desired professional profile for everyday life in health services. One of the alternatives adopted by nursing schools in the country is the methodology known as Tutorial. The aim of this study was to demonstrate the use of the tutorial as learning methodology for nursing education, verify student satisfaction regarding its use and identify the role of tutorial methodology on the construction of student’s critical stance in relation to the reality of health sector. As the tutorial is a student centered methodology where the teacher’s role is to guide them on the development of their professional career and personal life, the study has begun on the hypothesis that the tutorial leads to a meaningful learning, which stimulates the learning process and the student ability to meddle in the reality of the health system in which they are inserted. This was a case study with quantitative and qualitative methodological approach (mixed method). The research’s subjects were students of the second and fifth year of the nursing school at the University of Health Sciences of Alagoas. Data were collected using a structured questionnaire and a problem situation for the student to analyze and narrate their intervention. The answers to the questions were analyzed by Kruskal Wallis non-parametric test with a confidence interval of 95 % (p≤ 0.05) and the problem situation was investigated using content analysis. The results of both analyzes showed that the methodology of the tutorial has the potential to promote the development of a more critical and reflective capacity of the student. However...

Due to the growing concern for the environment, several Technologies for treatment of industrial effluents are being developed in order to minimize the impacts on water resources. Amid the various studied technologies, Advanced Oxidations Processes (AOPs) have received attention considerable. Among AOPs, the Fenton reaction, as source of generation hydroxyl radicals, has been outstanding. The Fenton reaction is the catalytic process of decomposition of hydrogen peroxide (H2O2) by ferrous ion (Fe2+) generating hydroxyl radicals, (HO•). The hydroxyl radical has a high oxidizing power, which leads to a partial or total degradation of large number of pollutants compounds. The ferrous ion, in appropriate pH, has the coagulant properties and may contribute to the removal of suspended particles in solution. The efficiency of the Fenton reaction can be enhanced when combined with the settling process. Depending of effluent, the sedimentation may be a slow step that can to reduce the application process on an industrial scale. The use of settler can accelerate the process, allowing the use of the method and also in continuous flow and also the use of iron concentrations higher, increasing the efficiency of treatment. In this study it was evaluated the efficiency of the coagulation processes...

Currently there is a clear trend of increased production of heavier oils, as oil reserves with better quality are being depleted. This implies the development of new refining technologies for the processing of these oils in order to maximize the acquisition of liquid fuels that are the main demand of the markets. The main process of refining is the fluidized catalytic cracking (FCC process) that requires an acid catalyst able to crack the hydrocarbon molecules present in the feed. The problem is that the current catalysts, formulated with Y zeolite, which has small pores, do not allow access of large molecules. This project will be studied the synthesis of mesostructure materials from a gel formed by seeds of Y and ZSM-5 zeolites. Therefore, in this project, we studied the synthesis of materials mesoestruturados from a gel formed by seeds of zeolite Y and ZSM-5 which has been submitted or not to adjust the pH to the range of 8-10 by addition of acid. From the physico-chemical characterizations was observed that all samples formed a phase mesoporous MCM-41 type. It was found that the materials synthesized from seeds of zeolite ZSM-5 had evidence of the presence of seeds of the solid mesoporous zeolites, regardless of whether or not samples subjected to pH adjustment. While the materials synthesized from seeds of zeolite Y with only those adjust the gel pH to the range 8 to 10 before the hydrothermal crystallization seeds showed evidence of the X-ray diffractograms and infrared spectra...

Recently, the textbook has taken up an important position about public politics of Brazilian education and it has been a matter of several researches in all the country. However, some criticism about the quality of this teaching material is done by several studious people. This research has the purpose to analyze the use which the teacher makes of the proposal of text production of Portuguese textbook of third grade of fundamental teaching and production conditions that are provided for the students. We analyzed five textbooks, the most used textbooks in Maceio and we observed five teacher s text practice of Municipal Teaching. Therefore, considering fundamentals practiced by National Curriculum Standard which advises about writing process, we realized the teacher s practical way contributes to educate competent writers at school. Referring to textbook use, the proposals about text production developed from this material are rare and, when they are made, they are connected with a traditional practice which not favors the handy writer s formation with written language. The teacher develops activities which not value interretional character. The texts are produced without any purpose. Furthermore, the opportunities which the students find to produce texts...
