George Nemeth, of Painesville, Ohio, learned of the blackout during a cellphone call with a friend whose power supplies, connecting several home computers, started beeping the alarms of an unexpected surge.
For indoor heating, a low-voltage supply connected to a conductive concrete floor makes the whole floor act as a radiator.
A pulsed direct current power supply connected to a substrate holder was used for negative biasing.
In most cases, sensor nodes employed in the network are low cost devices (with limited power supply) connected by possibly unreliable channels; so it is unrealistic to expect a perfect communication performance from them.
One possible rationale for the specificity of protoporphyrin accumulation in rapidly dividing cancer cells is that their enhanced metabolism demands additional heme, which is needed for increased aerobic ATP supply connected to the energy demands of the tumour.
Breathing was recorded in unrestrained Wt, Het and Null mice using a whole-body plethysmograph (Buxco II; Buxco Research Systems, Wilmington, NC), in which a constant bias flow supply connected to the animal recording chamber ensured continuous inflow of fresh air (1 l/minute).
