Guerra e o desenvolvimento científico: uma superaula interdisciplinar e investigativa construída em torno de um experimento central

This research presents the description of the assembly, development and execution of an experiment and of an interdisciplinary and student research activity built by some undergraduates from Biological Sciences, Physics, Mathematics and Chemistry PIBID subprojects of the Faculty of Science, FC - UNESP, Bauru/SP Campus. These subprojects are part of a single interdisciplinary group, which has as its main activity the Superclass, which consists of an intervention of the PIBID members during the class schedule, with an interdisciplinary and student research didactic sequence, applied by four groups of ten members, in two local State Schools. The experiment treated in this assignment was a miniature cannon (minicannon), and it was used in a Superclass that had the War and Science Development as its theme, wherein the knowledge of all areas were built from the analysis of the multiple variables involved on the cannon shots. These variables were surveyed with the students through the experiment research, during the Superclass, being focused on three of them: the shot and the explosives; the trajectory; and the target. The experiment was extremely successful, because it could instigate the students, who were interested, questioning and debaters for several times during the class. The minicannon made possible the interdisciplinary and the student research work among the four areas of science involved. Despite it has been a laborious experiment in its construction, it has proven to be innovative, and its use has transformed the students‟ ingenuous curiosity into epistemological curiosity, a key factor in the construction of scientific knowledge, wherein the dialogue established in the Superclass explored this new curiosity

Remoção pela chuva de diferentes formulações de flutriafol aplicada em soja, com e sem a adição de óleo mineral na calda

The present study had as objectives to verify the effect of rainfastness of different flutriafol formulations, in laboratory conditions, applied on soybean plants with and without the oil adjuvant in the spray solution, as well as to verify the influence of the oil on the droplet spectrum. The experiment considered ten spray solutions related to five treatments containing flutriafol (four formulations of flutriafol and a flutriafol mixture with tebuconazole), all applied with and without mineral oil. Particles size analysis were based on the determination of the droplet spectrum, medium volumetric diameter and the amount of droplets below 100 μm. All the solutions were sprayed with Teejet XR 11001 (fine droplets). Droplet spectrum was determined in a direct way by diffraction of laser (Malvern Mastersizer S®, version 2.15). Confidence interval at 90% degree was used to compare the mean data. The results showed that the addition of mineral oil in the solutions provided tendencies of larger medium volumetric diameter, smaller amount of droplets below than 100 µm and better uniformity of the droplet spectrum. All of the solutions with the addition of mineral oil presented larger adhesion and/or absorption of the fungicide on the plants in comparison with the solutions without oil. The increase of the time between the application and the rain, caused reduction of the fungicide removal, independently of the rain intensity. The increase of the amount of rain didn't change the relative behavior among the solutions; however, this larger amount of rain caused larger fungicide removal along the time. It was observed significant removal of flutriafol by the rain up to 48 hours after the spray application.

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
