Introduction. Experimental induction of spermatogenesis disorders is possible mainly by physical, pharmacological methods. However, not all methods can cause non-obstructive azoospermia. Objective. To evaluate and compare the effectiveness in rat models applying ligatures to spermatic cords administration cisplatin. Materials & . Seventy-three mature male rats (Wistar) were divided into 2 e...

This paper deals with the issues relevant for precise finite element method (FEM) modeling of thin molybdenum plates’ induction heating. The proposed methodology describes step-by-step Multiphysics (electro-thermal) design approach, verified by experimental measurements. Initially, it was observed that relative error between model and set-up is within 1.2% up to 2.5% depending on location measu...

The development of energy-efficient Power-to-Heat (PtH) technologies with high power density on a utility scale is key element in the future flexible energy systems. Although existing solutions for electric flow heaters (EFH) based resistance heating have efficiency, process outlet temperature and output are limited by lifetime contact elements. Inductively heated packed bed can achieve higher ...

Induction motor drive control and estimation is a wide subject. The market for variable speed drives has grown dramatically in the last few years. Manufacturers have recognized importance of not only managing or torque range, but also reducing power consumption. This necessitates development new algorithms schemes to include these solutions. Indeed, estimate must be employed one more regions sc...
