Aplicação de projeto de experimento no processo de manufatura de uma bobina de alumínio

TProducts must follow specifications in order to attend demands requested. In terms of rolled aluminum, one of the most significant items for customers is coil thickness. This is because only a tiny variation in thickness might cause a serious problem on customer's manufacturing line. Thereby, this research aims to analyze through design of experiments which factors and how they affect the thickness of aluminum coils. The response variable of the experiment is the thickness of aluminum coil, tensile strenght and yield strenght are the factors of the experiment and trimmers machines were considered as blocking. Data were obtained through tensile tests. The result of the experiment states that, according to the analysis of variance (ANOVA), while there is significant difference between the two levels of tensile strength, there is not any difference between the two levels of yield strength and trimmers machines. The thickness of the aluminum coils with high values of tensile strength tends to be thicker when compared with low values of tensile strength

A importância da ludicidade na escola na perspectiva de professores atuantes nos anos iniciais do Ensino Fundamental

The play and playfulness as well as school subjects are ways that the teacher has in the classroom to mediate the relationship between knowledge and the students, providing an easier and more enjoyable learning. This paper aims to analyze how teachers in the early years of primary education, the areas of Physical Education, Education, Art and English, assesses the importance of playfulness at school, define concepts such as the playful, playing, their importance for the learning and social life. Field research through interviews with nine teachers was conducted, six Educationalists teachers, an art professor, an English and physical education teacher. The results indicated that most of these teachers mediates learning through playfulness that children have better learning when the pedagogical work occurs through play, and feel more motivated to attend school. Participants have the idea that playfulness is the play and the play and say the school should value the playful, and need support from the school staff and the community. In conclusion, the playful should be part of everyday school life and more than a teaching strategy, should be valued in the integral formation of the individual
