The ministry report said, ''''These findings prove that the overgrowth of diatom plankton has resulted in a reduction in the nutrient salts in the sea, thereby causing the poor growth of ''nori'' seaweed.'''' Diatom plankton is a type of photo plankton. The number of creatures inhabiting the seabed, such as shellfish and shrimps, were small at many surveyed points, it said.''''There is the possibility that the fall in the number of these seabed creatures which consume the nutrient salts has resulted in the overabundance of nutrient salts in seawaters, thus causing the overgrowth of photo plankton,'''' the ministry said.The reclamation project has been under way since 1986 to create 1,840 hectares of farmland. The eight lock gates were shut in 1997.

Regular readers of this column will remember that one of my long-standing concerns with most commercial kitchen equipment is its inability to survive heavy cleaning sessions with pressure washers, hoses and the like.Too few manufacturers consider that to be enough of an issue to make changes in equipment to accommodate the types of cleaning methods used today. In one of my missives to a senior executive of one of the larger manufacturers, I begged him to go and observe what went on inside a commercial kitchen at 1 a.m. when it was time for the cleaners to do their job.

"We have a position sensor at each car wheel and a speed sensor for each side of the machine," added Jason Osborn, a design engineer who was heavily involved in the electronic development of the A220. "We have an onboard controller that knows exactly what angle and speed the wheels are turning at."When you flip the switch in the cab from AWS mode, the controller knows the heater wheels have to be in a certain spot to accomplish skid steering. It moves the wheels there and locks them in place. And in AWS mode it''s just the opposite, the controller knows that the wheels have to be allowed to turn to accomplish whatever steering the operator is trying to do."
