18. Application of methodology for the adequacy of the electrical motor's power sizing: permanent and transient analysis
Abstract The suitability of the motive force contributes to the efficient use of electrical energy. On the other hand, the inadequate size of electric motors is directly connected to increased investment and running costs. This article presents the theory and mainly the application of a methodology for the adequacy of the motive power. The research was condu

19. Comparative study of energy costs in irrigation according to the new brazilian electricity tariff model
ABSTRACT The tariff flags on Brazil came into force in January 2015, applied to all electrical distribution agents of the national interconnected system (SIN) and all final consumers are being charged for this new model. Given this, the cost of electricity in irrigation suffered representative additions involving searches of alternatives, such as the use of

22. The use of whole grain sorghum in broiler feeds
In broiler feed manufacturing, grinding may significantly increase costs due to electric energy use. This study evaluated the performance and the morphometrics of the gastrointestinal tract of broilers. According to a completely randomized experimental design, 2,400 birds (1,200 males and 1,200 females) were submitted to five treatments of eight replicates e
