Over time, the channel has been altered, wetlands drained and the flow of the water controlled and diverted for use in nearby cities and farms.
After sampling waters from the Pacific, Atlantic and Indian oceans at all latitudes, they found that the amount of AAPB in the water is controlled mainly by the level of planktonic algae in the region, rather than by the amount of light.

Someday, Peterson foresees, an integrated system will have track water trucks automatically controlled, based on the condition of the track at various points.

It's a 10-meter-long, 120-centimeter deep, fully automated stainless steel tub that produces pasteurized eggs by bathing them for about an hour in water that is precisely controlled to a temperature (the exact one is secret) between 54 and 66 degrees C.
It's a 30-foot-long, 4-foot-deep, fully automated stainless steel tub that produces a pasteurized egg by bathing it for about an hour in water that is precisely controlled to between 128 and 150 degrees (the exact temperature is secret)--hot enough to kill salmonella and other dangerous microbes without cooking the egg, (see sidebar).
Each was given carefully controlled salt-water injections in their jaw muscles to induce pain.
We saw a number of Electric Imp demos and appliance ideas at the booth including a simple hand-held "detonator" toggle switch with LED, seven-segment counter, water level sensor, servo-controlled gauge, RGB light, power socket, Christmas light, power monitor, toy washing machine, 16x16 LED display and receipt printer (the latter two being combined to show the avatars and tweets of anyone mentioning the Electric Imp) -- all Internet aware.

Lunn said the device puts a controlled electronic field into the water, which dissipates quickly, so there is no permanent damage to the shark.
On the other hand, access to fresh water represents a blessing, if rivers can be safely controlled.
That changed a lot when the heat of fire was used for boiling water into steam to drive industry, which became large scale and controlled by a few people with countless labourers and employees, whose smaller scale business had come to be totally outcompeted and had no choice but to accept the working conditions that suited these new tycoons.

As you know, yesterday BP began a controlled burn designed to remove large quantities of oil from the open water in an effort to protect shoreline and marine and other wildlife.
BrightSource generates electricity using an approach called concentrated solar power, in which computer-controlled mirrors, known as heliostats, focus the sun's heat to boil water and turn a steam turbine.
Farming fish close to shore often causes contamination of water and seabeds, so the company has partnered with fish producers to devise a remotely-controlled fish pen that can drift with currents in the open sea.
Examples of household electrical loads that could be shifted to off-peak hours via an automated or controlled mobile app include charging a plug-in vehicle, running a dishwasher, running a hot water heater, running the refrigerator's defrost cycle and ice-making.
