A constant-voltage and constant-current stimulus isolation unit.
When action potentials from a stimulated biological preparation are recorded i t is essential to isolate the stimulus resistively and capacitively from the ground in order to minimize stimulation artifacts. Such isolation can be achieved by using a transformer of special low-capacitance construction in the output of a stimulus generator (Donaldson 1958). The most widely used arrangement for the...
متن کاملComparison of turbulent thermal convection between conditions of constant temperature and constant flux.
We report the results of high-resolution direct numerical simulations of two-dimensional Rayleigh-Bénard convection for Rayleigh numbers up to Ra=10;{10} in order to study the influence of temperature boundary conditions on turbulent heat transport. Specifically, we considered the extreme cases of fixed heat flux (where the top and bottom boundaries are poor thermal conductors) and fixed temper...
متن کاملA comparison of turbulent thermal convection between conditions of constant temperature and constant heat flux
We numerically investigate turbulent thermal convection driven by a horizontal surface of constant heat flux and compare the results with those of constant temperature. Below Ra≈ 10, where Ra is the Rayleigh number, when the flow is smooth and regular, the heat transport in the two cases is essentially the same. For Ra> 10 the heat transport for imposed heat flux is smaller than that for consta...
متن کاملMeasurement of electrogenic-pump current in Aplysia neurones with constant-current and constant-voltage techniques.
1. The responses of the abdominal and pleural giant cells to warming and cooling were studied using constant-current and constant-voltage techniques. 2. The potential change upon warming from about 7 degrees C to 22 degrees C was reversed by application of maintained inward current. The reversal potential was -77 +/- 12 mV. 3. The membrane conductance increased with warming, but was not affecte...
