The present study attempted deriving and solving the falling- cylinder governing equations for power law model non-Newtonian fluids. Based on this theoretical study, a novel falling- cylinder rheometer (FCR) was designed and constructed to measure the Theological properties of non-Newtonian fluids. Different falling cylinders with predesigned densities were used to determine the apparent viscos...

The methamphetamine has been studied theoretically at the MP2 [1]/6-31G[2] level in gas phase.Methamphetamine has been investigated Via NMR, Frequencies Calculation and NBO analysis. Thestructure of methamphetamine was designed primarily using of Chem. Bio Draw and it geometry hasbeen optimized at the MP2/6-31G computational level. The present work consists the study of themethamphetamine repor...
