Results of educative actions on the control of vectors for dengue and leishmaniasis were evaluated by using an online semi-present course directed to teachers from Fundamental I Education level in Araçatuba-SP. 40 teachers from municipal schools located on geographical areas of town with higher occurrence of dengue and leishmaniasis cases, attended to the course, which consisted in a conceptual part directed to specific subjects such as vector borne and zoonotic diseases, responsible ownership of pets and health education and a practical phase, directed to execution and application of educative projects in the target schools. Data about the teacher’s specific knowledge, before and after the attendance to the course, were submitted to the Wilcoxon test with a 5% of significant level. The application of practical educative projects was evaluated by multiplicative actions involving target public. Tests showed statistically significant increase in the knowledge about the studied diseases (p<0.0001) after the course, especially on questions related to etiological agent, clinical symptoms on man and animals and prevention. Activities of knowledge multiplication envolved teachers and students which detected the problems and promoted education actions in their neighborhood as stage performing, group cleaning activities and elaboration and distribution of folders during a student pared. In conclusion, educative actions direct to the control of diseases vectors using a semi-present course, provides new knowledge to the teachers, impelling them to motivate their students to adopt vectors control measures and environmental cares and to sensitive the community to collaborate with control diseases.

An important phase of rehabilitation treatment, is the aesthetic and functional testing, performed with the patient. Its relevance is because at this time it’s possible to have a very faithful preview of the final result of the prosthesis, but, if necessary, still allow changes. Therefore, the objective of this review is to describe didactically the clinical steps and factors that should be examined by the dentist at the moment of aesthetic and functional testing of a complete denture. This clinical stage basically involves four requirements to be analyzed: mechanical, functional, aesthetic and phonetic. After the jointly analysis with all the requirements, the patient must approve, preferably in writing, the completion of the prosthesis. In case of need for any changes, this is when it should be performed, followed by new aesthetic and functional testing. It should be noted that the patient’s opinion is always sovereign in deciding to end the denture.

We present in this paper parts of the results of a research that had the intention to promote a space of communicative interaction among teachers of an undergraduate Course of Physics Teaching so they could plan their courses together. From the theoretical recommendations of the Theory of Communicative Action , by Jürgen Habermas , it was possible to draw a way of rationality crisis in training degree in physics in Brazil and then propose the creation of a Joint Planning Group (JPG) with teachers of specific nature disciplines of physics and disciplines about physics teaching. They start a joint discussion about the relationship among the disciplines in delivering of a project for future high school teachers' training. All meetings developed over a school year in the GPC were recorded, transcribed and analyzed with a part of a methodological analysis feature of the intersubjective interactions. This methodology was developed specifically for the research. The conclusions are related to the joint constructions developed by the JPG, its local contexts and the possibility of extension of this group. The joint constructions undertaken in the group point to the defense of the formation of JPG in the formation of the professors who teach these courses.

This work aims to find the maximum tension in a group of blades in a Sewage Treatment Stations in a company located in Vale do Paraíba. First, the calculations of the strength requested by the effluents on the structure are done, and the optimum torque of the frame screws is researched. From these data, static simulations using appropriate software and the finite elements method are performed. Based on the results, a possible solution to reduce the strength in this structure is proposed. This study will be provided as a consultation material to the company

The education designed and planned in a clear and objective manner is of paramount importance for universities to prepare competent professionals for the labor market, and above all can serve the population with an efficient work. Specifically, in relation to engineering, conducting classes in the laboratories it is very important for the application of theory and development of the practical part of the student. The planning and preparation of laboratories, as well as laboratory equipment and activities should be developed in a succinct and clear way, showing to students how to apply in practice what has been learned in theory and often shows them why and where it can be used when they become engineers. This work uses the MATLAB together with the System Identification Toolbox and Arduino for the identification of linear systems in Linear Control Lab. MATLAB is a widely used program in the engineering area for numerical computation, signal processing, graphing, system identification, among other functions. Thus the introduction to MATLAB and consequently the identification of systems using the System Identification Toolbox becomes relevant in the formation of students to thereafter when necessary to identify a system the base and the concept has been seen. For this procedure the open source platform Arduino was used as a data acquisition board being the same also introduced to the student, offering them a range of software and hardware for learning, giving you every day more luggage to their training

Direct methanol fuel cells (DMFCs) without external pumps or other ancillary devices for fuel and oxidant supply are known as passive DMFCs and are potential candidates to replace lithium-ion batteries in powering portable electronic devices. This paper presents the results obtained from a membrane electrode assembly (MEA) specifically designed for passive DMFCs. Appropriated electrocatalysts were prepared and the effect of their loadings was investigated. Two types of gas diffusion layers (GDL) were also tested. The influence of the methanol concentration was analyzed in each case. The best MEA performance presented a maximum power density of 11.94 mW cm-2.
