Supportive method, use

Matsushita Electric proposed a nodal line support method using a higher-order vibration mode [66]. A stator wide ring is supported at the nodal circular line and teeth are arranged on the maximum amplitude circle to get larger revolution. 

Azido-5 -deoxy-nucleosides auid 5 -azido-2, 5 -dideoxy nucleosides have been prepared by a polymer support method, using polystyrenesulphonyl chloride reagent in conjunction with lithium azide,which on triphenylphosphine reduction yielded the corresponding amino-sugar nucleosides. ...
