Renault Fluence Renault Z.E. program of electric vehicles. At the same show, the Israeli company Better Place announced the Renault Fluence Z.E. would be the first electric car with a switchable battery available on the network of battery swap charging stations that it is developing in Israel. The Fluence Z.E is outfitted with a 22 kWh lithium-ion battery which allows a total all-electric range of , with speeds up to . Sales of the Fluence Z.E. are scheduled for 2011 in Israel, Denmark and the rest of Europe, and for 2012 in the rest of the world such as Asia. At the
Quantitative models of the action potential that again, there are only two time-dependent variables: the transmembrane voltage "V" and the potassium gate probability "n". The bursting, entrainment and other mathematical properties of this model have been studied in detail. The simplest models of the action potential are the "flush and fill" models (also called "integrate-and-fire" models), in which the input signal is summed (the "fill" phase) until it reaches a threshold, firing a pulse and resetting the summation to zero (the "flush" phase). All of these models are capable of exhibiting entrainment, which is commonly observed in nervous systems. Whereas the above models simulate the transmembrane
