巴甫洛 is the prefix you'll see most often as part of
巴甫洛夫 (Bāfǔluòfū) — Ivan Pavlov (1849-1936), the Russian physiologist whose conditioned-reflex experiments with dogs founded behaviorism. Standalone,
巴甫洛 transliterates the Ukrainian/Slavic given name Pavlo (equivalent to Paul). The choice of characters —
巴 (bā),
甫 (fǔ),
洛 (luò) — is purely phonetic.
