This exercise examines the effect of the threshold potential on an action potential for the squid giant axon. The Hodgkin-Huxley parameter values
squid giant axon for a very long time. At time t=0, the current pulse is removed. Simulate the resultant action potential. (b) The value of the threshold potential is defined as when INa >IKþIl. Changes in threshold potential can be implemented easily by changing the value of 25 in the equation for am to a lower value. Suppose the value of 25 is changed to 10 in the equation, defining am and a current pulse of 10mA (hyperpolarizes the membrane) is passed through the membrane of a squid giant axon for a very long time. At time t¼0, the current pulse is removed. Simulate the resultant action potential.
The feed (CAo= 1.0, CRo= 0, CSo= 0) enters two mixed reactors in series (?1= 2.5 min,?2= 10 min) knowing the composition in the first reactor (CA1= 0.4, CR1= 0.4, CS1= 0.2),find the composition leaving the second reactor (using fractional yield co..
The circuit is to be tuned to the first station at a frequency of 1000 kHz. In order to minimize the interaction between signals, the tuning circuit response must attenuate the signal of the second station (with a frequency of 1020 kHz) by four ti..
If a delta-connected capacitor bank, with a per-phase reactance of 60 Ω, is connected in parallel with the load at its terminals, compute the resulting line-to-line voltage at the load terminals.
A transformer has its maximum efficiency of 0.9800 when it delivers 15 kVA at unity power factor.
A sealed rigid tank is filled with 1 kg of steam at 200 °C and 10 bar. What is the volume of the tank? 0.5 kg of steam are removed from the tank. If the temperature remains at 200 °C, what is the new pressure in the tank?
2. Alcohol is a diuretic agent, which increases urine production by reducing water reabsorption. Normal rate of water reabsorption is about 124 ml/min. Assume that the effect of alcohol on water reabsorption (in ml/min) is given by the following equa..
Write a comprehensive report on your selection of the form of corrosion - Discerption of the corrosion form.
The data in Table 1 were obtained from a kinetic study of an enzymatic reaction. The substrate S (with a concentration s) was converted, using an enzyme, to a product in 4 different experimental runs. The initial conditions of each experiment (initia..
Develop the four first-order ordinary differential equations that model the Michaelis-Menten equation when the transition step from ES to E + P is reversible (not assumed to be irreversible).
The armature-circuit resistance is 0.25 Ω and the series-field resistance is 0.25 ?4. Calculate the speed of the motor
Crude dichlorobenzene is pumped from a storage tank to a distillation column. The tank is blanketed with nitrogen and the pressure above the liquid surface is held constant at 0.1 bar gauge pressure. The minimum depth of liquid in the tank is 1 m.
Calculate the rate of moisture condensation (kg/h) and the volumetric flow rate of the air drawn from the outside.
