13. SALA DE AULA INVERTIDA NO ENSINO DA QUÍMICA ORGÂNICA: UM ESTUDO DE CASO
The flipped classroom is one of the types of rotation model strategies that aim of increasing interaction and personalized contact time between students and teachers in the classroom setting. In this study, we investigated the application of the flipped classroom strategy in two classes of the different semesters in the discipline of Organic Chemistry. The t

15. MONITORING TRACTOR PERFORMANCE USING SHEWHART AND EXPONENTIALLY WEIGHTED MOVING AVERAGE CHARTS
ABSTRACT Statistical process control has been widely used in agricultural operations for monitoring and improving process quality. This study aims to evaluate the Shewhart and exponentially weighted moving average (EWMA) control charts to monitor the performance of an agricultural tractor–planter set. The design is completely randomized based on the assump

16. Strategies used to control the costs of underground ventilation in some Brazilian mines
Abstract In an underground mine, the ventilation is responsible for 25% to 50% of its electrical energy consumption. In countries such as South Africa, United States and Canada researchers have started to achieve a significant reduction in energy consumption without neglecting aspects of the quantity and quality of air required for the best performance of th

17. THEORETICAL ANALYSIS AND EXPERIMENTAL STUDY ON THE PROCESS OF CONVEYING AGRICULTURAL FIBER MATERIALS BY SCREW CONVEYORS
ABSTRACT To improve the conveying efficiency and working stability of a screw conveyor, the feeding methods, running conditions and flow characteristics of materials were studied by theoretical analysis and experiments. The theoretical analysis results show that the screw conveyor runs more stably when the helix angle of the screw blade is equal to the movin

20. Editorial Comment: Lessons learned after 20 years' experience with penile fracture
ABSTRACT Introduction: Minimally invasive treatments such as extracorporeal shock wave lithotripsy and percutaneous nephrolithotripsy are standard procedures for the management of renal stones (1). However, renal position and rotation defects may significantly interfere in the results of these treatments (2). Open surgery has always been an option for these
