The Electrical Conductivity of Pure Protoplasm
The electrical conductivity of the plasmodium of the slime-mold Brefeldia maxima (Fr.) Rost., which constitutes practically pure protoplasm, was found to be approximately equivalent under normal conditions to that of a 0.00145 N NaCl solution, and about 2.8 times that of the liquid in contact with which it developed. When bathed in 1 per cent sea water, the conductivity was much increased, beco...
متن کاملThe Study of Thermal Conductivity Silver/Water Nanofluid
In present study, the thermal conductivity of silver/water nanofluid was investigated experimentally. Four different volume concentrations of nanofluids (2, 3, 5 and 10%) were prepared by dispersing silver nanoparticles in water. The properties of nanofluids were measured by varying the temperature from 20ºC to 100ºC and also, different sizes of nanoparticles dispersed in water (20-30, 50-60 an...
متن کاملPure Electric Vehicles
While creating an industrial system which has an electric motor, the designers should to be think over not only control method but also motor type to create successful and efficiency system. If created system is an electric vehicle, designers have two powerful candidates as traction motor: Brushless AC (BLAC) or Brushless DC (BLDC) motors. In this study, a comparative performance investigation ...
متن کاملElectrical stunning of fish: the relationship between the electric field strength and water conductivity
The electric field in water required to stun trout is investigated experimentally. The results show how the electric field depends on water conductivity. The electric fields in water required to generate permanent insensibility in trout following exposure durations of 15, 30 and 60 s are identified. A mathematical model of the electric field in the stunning tank is constructed and shown to prod...
متن کاملThe Sensing of Electrical Capacitances by Weakly Electric Mormyrid Fish: Effects of Water Conductivity
Weakly electric fish can perceive electric properties of objects by monitoring the responses of their epidermal electroreceptors (mormyromasts) to their own electric organ discharges (EOD), a process known as active electrolocation. Mormyrid fish can distinguish capacitative from resistive properties of objects. It is mainly animate objects that possess capacitative properties. Water conductivi...
