contamination control, reversible attachment is a concern. Particles on the floor that are not completely contained or trapped onto a surface will eventually, through air movement and vortices, become re-suspended into the air. Previous studies have shown that transfer of contamination by people walking across floors has one of the highest re-dispersal factors7. One of the measures commonly emp...

Altering the time base required physically changing the ramp generator. In this article a new method of generating the sweep deflection ramps is presented that permits changing the sweep rate by computer control without replacing the ramp generator. A logic level signal can now be used to change sweep rates without the need for invasive component changes. This new development permits fast and e...

Results suggesting that changing perspective and switching across spatial environments held in memory are processes that take place in parallel were obtained from a task-switching experiment. Participants learned layouts of objects in two virtual rooms and then were asked to use their memories to locate the objects from various imagined viewing perspectives. Results revealed that, even after ex...

BACKGROUND General practice has rapidly computerised over the past ten years, thereby changing the nature of general practice rooms.

General practitioners (GPs) and patients have had to integrate the computer into...
