Use the Hodgkin-Huxley model (equations and parameters from Hoppensteadt) for the nerve action potential to estimate the following:
a) The voltage threshold for excitation.
b) The current threshold for excitation.
c) The refractory period for stimulation with a current of 10 microAmperes/cm2 and duration 1 ms.
d) The relationship of the frequency of action potentials to the strength of a continuous stimulatory current.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
