If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

The electrocardiogram (ECG) records from the body surface and registers the differences in electrical potential generated by the heart. The signal recorded is determined by action potentials generated by millions of individual cells and their sequence of activation. A multitude of factors, both cardiac and extracardiac, alter the final electrical signal. For instance, the electrical forces ...

The electrocardiogram (abbreviated as ECG or EKG) represents an electrical tracing of the heart and is recorded noninvasively from the surface of the body. The word ECG derives from the German language. In German, it is elektrokardiographie. In 1902, the Dutch physician Einthovan invented ECG, and his tremendous input in clinical studies for about ten years led to full recognition of the ...
