Axons transmit signals to other neurons by means of specialized junctions called synapses. A single axon may make as many as several thousand synaptic connections with other cells. When an action potential, traveling along an axon, arrives at a synapse, it causes a chemical called a neurotransmitter to be released. The neurotransmitter binds to receptor molecules in the membrane of the target cell.
An axon can connect to how many other cells?
several thousand

House also had an influence of relaying political messages to people who were considered to be outcasts of society. The music appealed to those who didn't fit into mainstream American society and was especially celebrated by many black males. Frankie Knuckles once said that the Warehouse club in Chicago was like "church for people who have fallen from grace" The house producer Marshall Jefferson compared it to "old-time religion in the way that people just get happy and screamin'". Deep house was similar to many of the messages of freedom for the black community.
where was the warehouse club located?
Chicago

In the former Soviet Union, electric traction eventually became somewhat more energy-efficient than diesel. Partly due to inefficient generation of electricity in the USSR (only 20.8% thermal efficiency in 1950 vs. 36.2% in 1975), in 1950 diesel traction was about twice as energy efficient as electric traction (in terms of net tonne-km of freight per kg of fuel). But as efficiency of electricity generation (and thus of electric traction) improved, by about 1965 electric railways became more efficient than diesel. After the mid 1970s electrics used about 25% less fuel per ton-km. However diesels were mainly used on single track lines with a fair amount of traffic so that the lower fuel consumption of electrics may be in part due to better operating conditions on electrified lines (such as double tracking) rather than inherent energy efficiency. Nevertheless, the cost of diesel fuel was about 1.5 times more (per unit of heat energy content) than that of the fuel used in electric power plants (that generated electricity), thus making electric railways even more energy-cost effective.
What year could be marked as year when electric railways more efficient than diesel ones?
1965
