Hepatitis E is a potentially serious acute disease. It is caused by the hepatitis E virus (HEV). The virus targets the liver. According to the World Health Organization (WHO), 20 million cases of hepatitis E infection occur every year, and 57,000 of them result in death (WHO). It is more common in developing countries. Hepatitis E usually resolves itself but may develop into acute liver failure.
The kilowatt (kW) is equal to one thousand (10 3) watts. This unit is typically used to express the output power of engines and the power of electric motors, tools, machines, and heaters. It is also a common unit used to express the electromagnetic power output of broadcast radio and television transmitters.
The real power P in watts (W) is equal to 1000 times the apparent power S in kilovolt-amps (kVA), times the power factor PF: P (W) = 1000 Ã S (kVA) Ã PF. So watts are equal to 1000 times kilovolt-amps times the power factor.
