I would like to know a general procedure for the synthesising cis isomers from their trans counterparts and vice versa. The possibility for cis-trans isomers when the double bond is between the 2nd and a photoisomerization is the conversion of one isomer into another isomer by light. A recent study found that the gender identity of trans children is as implicit as the gender identity of cis children a study with 32 transgender children, ages 5 to 12, indicates that the gender identity of these children is deeply held and is not the result of confusion about gender identity or pretense.
