A power supply including an inverter receiving a DC input signal from a DC input source. Methods of using these conjugates in the treatment of prostate diseases are also provided. The substrates have alignment layers on their mutually opposing inner surfaces. The body has a lower end, a receiving space defined in the body, a sliding hole defined through the lower end and a channel. The heterostructure includes a buffer layer having a lattice constant intermediate that of the n- and p-channel materials and which is configured to accommodate the strain produced by a lattice-constant mismatch between the n-channel and p-channel materials. cooler than the feed temperature of the liquid reaction mixture to the flasher and the concentration of acetic acid in the crude product vapor stream is greater than 70% by weight of the crude product vapor stream.
