Often referred to as party barges. Pontoon and deck boats are typically seen with multi-hulls, although there are also deck boats without pontoons, which have a monohull. Both boats are designed primarily for day use as an entertaining platform.
A ventricular assist device (VAD), also known as a heart pump, is a mechanical device that helps pump blood from the heart to the rest of your body. A VAD can be implanted in the chest or worn outside the body. If it is implanted, surgery is done to place it in the chest area. The pump part of the VAD is placed in a small space in your upper abdomen.
Volt-ampere (VA) is a measurement of power in a direct current ( DC ) electrical circuit. The VA specification is also used in alternating current ( AC ) circuits, but it is less precise in this application, because it represents apparent power , which often differs from true power . In a DC circuit, 1 VA is the equivalent of one watt (1 W). The power, P (in watts) in a DC circuit is equal to the product of the voltage V (in volt s) and the current I (in ampere s): P = VI. In an AC circuit, power and VA mean the same thing only when there is no reactance .
