The remarkable slow velocity fits with the pace of spreading depression (SD), a profound but transient all-or-none type process characterized by redistribution of ions across cell membranes and nearly complete neuronal depolarization [10], [11].
Corresponding spreading is occurring at an even faster pace in the Pacific Ocean; in the Atlantic, however, the slower rate of spreading causes the flanks of the ridge to be built up steeply by accumulating lava.
Craft guilds broke down as the pace of technological innovation spread and new opportunities for trade disrupted their hold over a particular industry.
This fast pace of Ebola's spread is a grim reminder that epidemics are a global threat and that the only way to get this virus under control is through a rapid response at a massive global scale much stronger than the current efforts.
The Middle Cretaceous (from about 120 100 million years ago) was an interval of major changes in atmospheric chemistry, the pace of sea-floor spreading was high, the magnetic field was in a stable normal polarity "superchron," and average global temperatures were on the rise.
The pace and spread of developments in mobile technology and medically relevant applications is in stark contrast to the much slower rhythms of research and subsequent publication of evidence.
The idea is to allow the fire to spread upwind, where the pace of its progress is slow, but to prevent any spreading downwind, which could easily get out of hand.
"It is crucial that response efforts out-pace the spread of this highly infectious disease and this good neighborly action will help MHMS achieve this; and we are sure MHMS will replenish to Fiji as soon as they can".
The pace of recovery picked up as word spread that rewards were offered for items returned.
These decentralized threats grow out of the widening spread and quickening pace of globalization and are magnified by it.
