One of the main reasons for failure in cancer chemotherapy is the selective growth of drug resistant cells during treatment. Agents that are non-toxic and can reverse this drug resistance is of great value to cancer chemotherapy. Rhizoma Alismatis, its extracts and fractions or chemicals isolated fr.....

Existing methods for multi-string applications require many windings in the isolation transformers because each converter output needs one winding. This invention, a dimmable LED driver, can reduce the number of windings. It also possesses a two-secondary-winding structure to generate several source.....
