From this knowledge management definition we can see that it depends upon the management of the organization's knowledge creation and conversion mechanisms; organizational memory and retrieval facilities; organizational learning; and organizational culture.
A leaky mitral valve, or mitral regurgitation, can develop when the valve flaps (called leaflets) do not close effectively. This can happen either because the valve flaps are scarred or defective, or because the heart has become enlarged, stretching the valve opening so much that the flaps no longer meet in the center.
Differential area relief valves must have seals to prevent leakage. Most counterbalance valves have one to three dynamic seals in them, which introduce friction, resulting in hysteresis. Friction caused by the dynamic seals makes the valve stick, causing an overshoot in pressure. The counterbalance valve then shifts to correct itself and undershoots. The result of hysteresis is bounce, loud chatter, or high-pitch squealing. Sometimes this chatter is caused by the design of the cylinder, not the counterbalance valve. The more dynamic seals in the counterbalance valve, the greater the hysteresis will be. When caused by the cylinder, no counterbalance valve in the world can reduce this chatter. Treat symptoms or the cause. Many counterbalance valves offer options to treat the symptoms. Most counterbalance valves come with a pilot ratio anywhere from 1.75:1 to 12.0:1.
