ELECTRICITY/effectsHYPOTHERMIA/experimentalIN our experiments we applied direct current at 220 V., or alternating current, through a resistance with which the potential could be varied between 10 and 220 V. The current passing through the animals was registered by milliammeter. Copper electrodes were...
Currently transportation accounts for 30% of global energy consumption, thus posing a challenge to the net-zero energy transition3. In the UK, electrification of the current car fleet requires an estimated additional 26.5% of the current electricity usage4. This extra demand alone is comparable to...
No obvious differences between the stimulated side and the control side were observed in the morphological and biochemical studies, but characteristic thickening of the growth plate caused by the accumulation of hypertrophic cells was found in the group stimulated for 2 weeks. Electricity affects the ...
The presented conceptual provisions for the creation of unified energy zones aimed at ensuring a fair redistribution of cross-subsidization between electricity consumers and a gradual reduction in its consumption will make it possible to form a unified energy space of Russia. On a concrete example, ...
