This article discusses the evaluation of three methods static contact angle measurements de-ionized (DI) water and TiO2 nanofluid droplets with concentrations (0.5%, 1%, 5%) that evaporate on substrate different temperatures. To compare discussed approximation methods, differences between results mean angles were identified; highest standard deviation was recorded for Young–Laplace circle such ...

Learning about statistics is a lot like learning about science: the learning is more meaningful if you can actively explore. This series in Advances in Physiology Education provides an opportunity to do just that: we will investigate basic concepts in statistics using the free software package R. Because this series uses R solely as a vehicle with which to explore basic concepts in statistics, ...
