For most electronic equipment such as radios, computers, etc, you can assume all kVA at the input will end up as generated heat. That's conservative, obviously.If you can actually measure the input current when the equipment is running, you'll get a good feel for the probable losses. ...
The models are validated using experimental results, which have been obtained from the normal heat run test performed by the transformer manufacturer at varying load current on a 250-MVA-ONAF-cooled unit, a 400-MVA-ONAF-cooled unit and a 2500-KVA-ONAN-cooled unit. The results are ...

Two features common to diverse sick excitable cells are “leaky” Nav channels and bleb damage-damaged membranes. The bleb damage, we have argued, causes a channel kinetics based “leakiness.” Recombinant (node of Ranvier type) Nav1.6 channels...
