The fact that most fluids in nature do no obey Navier-Stokes eqs. manifests engineering & industrial importance of non-Newtonian fluids. The 2nd and 3rd grade fluids which form a subclass of differential type fluids can predict shear thinning and thickening properties but lack other feathers such as stress relaxation and retardation. Maxwell and Oldroyd-B fluids models which are viscoelastic rate type fluids can show relaxation and retardation phenomena. Burgers fluid which is a viscoelastic fluid model includes an Oldroyd-B, Maxwell and Newtonian fluid models as special cases....

The manuscript contains new results of magic labeling on trees and their properties, labeling patterns will be discussed and then generalization of the results will be offered. In our study, first we includes introduction, history and labeling of graphs. Secondly, we will give some basic concepts, notations and terminologies about graphs which are important to provide strong and enough basis of the present study. Thirdly, we include basic idea of graph labeling with a special interest of magic labeling. and at the last, we discussed super edge magic labeling of trees, making base "Every...
