Synthesis, complete assignment of 1H- and 13C-NMR spectra and antioxidant activity of new azine derivative bearing coumarin moiety

In Brow Growth Treatments this research, the synthesis of a new azine derivative with coumarin moiety was performed in three reaction steps, starting from 4-hydroxycoumarin.The first step in synthesis was the acetylation of 4-hydroxycoumarin to yield 3-acetyl-4-hydroxycoumarin and then the obtained 3-acetyl-4-hydroxycoumarin was reacted with hydraz

Intuitive Mechanics: Inferences of Vertical Projectile Motion

Our intuitive knowledge of physics mechanics, i.e.knowledge defined through personal experience about velocity, acceleration, motion causes, etc., is often wrong.This research examined whether similar misconceptions occur systematically in the case of vertical projectiles launched upwards.The first experiment examined inferences of velocity and acc
