Principles
The particles of the universe are in constant motion – tumbling spinning and interacting in both chatic and in orderly fashions. The speed with which they move about relates to the energy they have – and is directly related to the heat that they contain. As they move about they interact with one another based on forces in the environment and forces that are innate. The forces may be attractive or repulsive in nature. The electrical forces of negative ands positive make the most intuitive sense. Opposite electrical forces attract and similar forces repel.

Strong Nuclear Force
This force is responsible for holding positively charged protons together in the nucleus of the atom superceding the repulsive forces of similalrly charged particles.

Mechanical Disease
Flow in this tube is demonstrated by the arrows going from right to left through a narrowingin the tube (red) demonstrating a vacuum or suction effect caused by the sudden acceleration of the fluid as it goes through the narrowing or stenosis. This is seen in the U shaped monometer with the fluid level in blue being relatively higher at the site of the stenosis in relation to the pressure more upstream. The suction phenomenon is kown as the Venturi effect is seen in IHSS where the narrowing of the LVOT causes a vacuum effect on the anterior leaflet of the MV resulting in mitral regurgitation. The Venturi effect is also utilised in the functioning of carburettors in fuel driven engines. 34807b05 code heart cardiac SAM IHSS pressure drop vacuum suction acceleration stnosis Venturi effect tube principles |
