Application of Prandtl’s Theory in the Design of an Experimental Chamber for Static Pressure Measurements [PDF]
Sensors, 2021 Pumping in vacuum chambers is part of the field of environmental electron microscopy. These chambers are separated from each other by a small-diameter aperture that creates a critical flow in the supersonic flow regime.

Pressure redistributing static chairs for preventing pressure ulcers [PDF]
Cochrane Database of Systematic Reviews, 2022 Sitting can be viewed as a therapeutic intervention and an important part of a person's recovery process; but the risk of ulceration must be mitigated. Interventions for ulcer prevention in those at risk from prolonged sitting include the use of specialist cushions and surfaces, especially for wheelchair users.

Considerations on static pressure gradients in closed circulatory systems [PDF]
Physiological ReportsSiphons are devices that transport liquids uphill between two containers. It has been proposed that a siphon principle operates in closed circulatory systems, as best exemplified by the circulation of blood in mammals.
