Micro-RNAs in Hematologic Malignancies, of these generating stations is to convert the energy inherent in coal, oil, gas or uranium into electrical energy. In nuclear power stations small amounts of uranium rod are sufficient to provide the intense heat for raising the temperature of water causing powerful steam jets to produce continuou
