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
Effectiveness of a Snowboarding Simulation Using the Distinct Element Method
Some snowboarding simulation methods have been developed.Although snow has unique properties such as granular material and continuum, few snowboard simulation methods can reproduce the discrete behavior of snow.Conventional simulations are unsuitable for reproducing the characteristics of snow when ski and snowboard turns carve eye and lip balm thr
Investor Protection in Indonesia: Financial Ratios as Early Warning Indicators
The Indonesian government aims to enhance public engagement in the capital market by strengthening investor protection and financial literacy through the establishment of a Watchlist Board.This study identifies the most effective financial ratios for dis tinguishing between the performance of LQ45 and Watchlist Board firms.Using dis criminant analy
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
