...diology in Atlanta. The team studied 228 valves removed from patients who underwentvalve-replacement surgery from 1994 to 1997 at the Hospital of the University ofPennsylvania. Organized, hard-bone tissue--identical to that found in a livinghuman skeleton--was found in 30 of the valves, which, acc...Fish Farmers Must Learn Zebra Mussel Prevention From A To Z
...any hard surface, including aerators, water supply valves and filtration systems. Because zebra mussels are filter feeders, they prefer settling in high-current areas which will bring a lot of food their way -- such as an intake pump.
