Developments in eccentric screw pumping have been very conservative.Concepts are still applied today which were in widespread use 20 years ago. Attempts to enhance the screw pumping effect, by adjusting rotor/stator geometry for example, have repeatedly yielded only variations in existing performance.
Another possibility for performance enhancement is to examine applications for progress made in the wider engineering field, and to apply suitable advances to the eccentric screw pump. With this in mind,three components of the pump lend themselves demonstrably to enhancement: the joints, the pump-drive coupling and the sealing system.

The authors determine the utility of applying two display design principles toward the development of interfaces for engineering design. The first principle, called the Proximity Compatibility Principle, specifies that displays relevant to a common task or mental operation should be rendered close t
