Urea-denaturing gel electrophoresis of 22 species of human mt-tRNAs isolated from human placenta by chaplet column chromatography. The “crude” lane stands for placental total RNA. Each tRNA species is denoted by the single-letter abbreviation of the corresponding amino acid. ...
Today, total synthesis stands as the flagship of organic synthesis, reflecting and symbolizing its powerful state of the art and providing synthetic avenues to the most complex and precious molecules found in living nature. Indeed, the practice of total synthesis of natural products provides challenge...

6. The symbol δ(lower case Greek delta) should be used for chemical shift scales with the sign con-vention given above. Such a symbol should neverbe used to refer to shielding. These recom-mendations cohere with the definition of the δ-scale adopted in refs. 1 and 2. The definition ...
In formula (1b), EWG is as defined for formula (1a); the symbol “q” is a substituted or unsubstituted, straight, branched or cyclic alkylene group of 1 to 10 carbon atoms or a substituted or unsubstituted arylene group of 6 to 18 carbon atoms, for example, 1,4-phenylene, 1,3-...
For these elements, the symbol usually refers to an older name that isn't used anymore. History of the Abbreviations There are eleven element abbreviations that don't seem to match their modern names. Those are subtle reminders of thehistory of the Periodic Tableand the process of the discover...
