The independent variables include: poverty rate, population density, literacy rate, the percentage of nonagricultural employment, the percent of households with electricity, distance to the district hospital, ethnicity (i.e., Tai-Kadai vs. other), and religion (i.e., Buddhist vs. other).
Only high-voltage alternating current could transmit electricity any distance, making it a far more flexible and superior technology.
The economic performance of over-the-fence process integration depends on the cost of fuel, electricity and distance for the transfer of waste heat to DH network.
In 2009, 26 township neighborhoods were matched on size (450 600 households), density, public utilities (water, electricity, toilets), distance of primary health care, and the number of alcohol bars.
In Burkina Faso and Tanzania these included the availability and cost of water and electricity, the distance to one's family and being poorly informed about new developments in the health sector.
The need to send electricity long distances enshrined alternating current as the basis of our own vast electrical grid.
Sandford Flemming, a Scottish-Canadian railway engineer, was the first to propose a system of world-wide time zones in 1889: "the twin agencies steam and electricity" annihilated distances and made reform necessary.
The technology comes from MIT spinoff WiTricity, which specializes in "wireless electricity delivered over distance".
Typical sources of these EM emissions include television sets, video display terminals (VDT), electric appliances, fluorescent lights, certain medical devices, walk-through and hand-held detectors, radio stations, induction heating, wireless electricity delivered over distance, hybrid cars and transmission lines.
Instead, the grid was intended to be a highly reliable way to move electricity relatively short distances.
He points to the example of high voltage direct-current cables, an innovative means of delivering electricity over long distances.
