Harmonic, Non-Euthanasic and Non Euthanasic are both wrong. Noneuthanasic is correct. According to Webster's and the Chicago Manual of Style, prefixes are linked without hyphens or space in most situations.

Also, I'd lowercase the O in "Of."

If you're preparing the article for publication, the style of the publishing house will determine hyphenation and capitalization in headings.

Harmonic, Glad to help. Good luck with the article.
