Power quality complex estimation at alternating current traction substations

open access: yesNauka ta progres transportu, 2013
Purpose. At alternating current traction substations are used three-winding transformers. This scheme comes to significant costs from power quality disturbances at each supplier.

Stimulation of an entorhinal-hippocampal extinction circuit facilitates fear extinction in a post-traumatic stress disorder model

open access: yesThe Journal of Clinical Investigation
Effective psychotherapy of post-traumatic stress disorder (PTSD) remains challenging owing to the fragile nature of fear extinction, for which the ventral hippocampal CA1 (vCA1) region is considered as a central hub. However, neither the core pathway nor

Experimental and Analytical investigations of the actions taking place in a synchronous machine during the starting period when the starting is effected by means of alternating current

open access: yes, 1918
The literature on the subject of the present investigation is somewhat meagre. A rotary converter or synchronous motor no! provided with any special starting devices forms, when started from the alternating current side, a type of induction motor whoso Htator is provided with a polyphase winding, and whoso rotor has a single-phase (or single magnetic ...
