A Internal Positive Pressure aid is an artificial aid for breathing used if you have problems with your muscles or lungs.

Our bodies have an internal pressure equal to that of the atmosphere (101000 pascals). Once the external pressure on you body exceeds this internal pressure enough your body will implode. This external pressure can be provided by water. Depending on how you go about going that far below water and the specific tolerances of your body a deadly depth can be from 500 to 1200 feet.
PVC - Positive Crankcase Ventilation. Used to allow the engine to vent out pressure that is creates while operating. Generally it is vented back into the air intake system after the air filter to get "burned" in the combustion chamber.
Transducer (i.e. a device for converting energy from one form to another) for both vacuum and positive pressure.
No, internal resistance cannot be negative. In electrical systems, internal resistance represents the opposition to the flow of current within a device, such as a battery or capacitor, and is always a positive value. Negative resistance is a concept that can occur in certain non-linear devices, but it is not applicable to traditional internal resistance in passive components.
The internal water pressure in plants is countered by the cell wall. This is called turgor pressure.
points in your body that hurt when pressed or when pressure is applied.

Pressure can be both internal and external. Internal pressure refers to the force exerted by a fluid within a closed system, while external pressure can be the force exerted by a substance or object outside of the system onto the system.
An aid in internal control over payrolls that indicates employee attendance is a clock card. It can also be referred to as a time clock.

The internal pressure of the lungs is controlled by the diaphragm and the muscles of the thorax (chest). Inhalation is caused by increasing the volume (which lowers the internal pressure) while decreasing the volume (increases the internal pressure) leads to exhalation, similar to the way a bellows works. The elastic qualities of the lung also help the process of exhalation.
For many individuals, music serves as a positive work-enhancing ergogenic aid.

The difference between external pressure and internal pressure in a rocket influences its ability to ascend and maintain stability. If the internal pressure is significantly higher than external pressure, the rocket can generate thrust effectively, allowing it to travel greater distances. Conversely, if external pressure exceeds internal pressure, it can result in structural stress or failure, limiting the rocket's range and potentially causing it to descend prematurely. Thus, managing this pressure differential is crucial for optimizing flight performance and distance.
The internal energy of an ideal gas is directly proportional to its temperature and is independent of its pressure.
