However, DC transmission was hampered by the difficulty in changing voltages between industrial generation and residential / commercial consumption and the low voltages used suffered from poor transmission efficiency.

Synaptic plasticity is among the electrophysiological phenomena used to control the efficiency of synaptic transmission, long-term for learning and memory, and short-term for short transient changes in synaptic transmission efficiency.
23.
Although the short life span outside plants inhibits long-distance viral transmission, it does not reduce the transmission efficiency bestowed by the quick rate of viral acquisition and inoculation within a field.
24.
Indeed, the spectrum already has been " expanded " many times over the past century by technological advances that have increased the number of usable frequencies, reduced interference and improved transmission efficiency.
25.
Transmission efficiency is greatly improved by devices that increase the voltage ( and thereby proportionately reduce the current ), in the line conductors, thus allowing power to be transmitted with acceptable losses.
26.
Virus-vector interactions ( i . e ., specificity of aphid species, acquisition access and retention times, semi-persistent manner of transmission, and transmission efficiency ), and the inability to transmit the virus via sap were established by Frazier ( 1955 ).
27.
Research using " Aspergillus " species indicated that transmission efficiencies might depend on the hosts viral infection status ( infected with no, different, or same virus ), and that mycoviruses might play a role in the regulation of secondary mycoviral infection.
28.
The methodology considers the upstream efficiency of the processes involved in the two fuel cycles, and considers the national average electricity generation and transmission efficiencies because a battery electric vehicle burns its fuel ( mainly fossil fuels ) off-board at the power generation plant.
29.
Typical CVT designs require high level of hydraulic pressure for operation, and CVT hydraulic-fluid pumps are typically driven at the same rate as engine speed, leading to pumps wasting considerable effort, lowering transmission efficiency at higher engine speeds as the pump moves more fluid than necessary to lubricate and sandwich the CVT's belt.

On March 23, 1951, Hush-A-Phone and Harry C . Tuttle submitted filings to the FCC reporting scientific tests proving that the Hush-A-Phone " actually causes a net increase in'transmission efficiency of the telephone circuit " and that AT & T and affiliates were " public utility monopolies unlawfully interfering with the natural and inherent rights of a subscriber ".
