In the present paper, we have focused our attention to highlight the study of a non-Newtonian nanofluid between coaxial cylinders with variable viscosity. The governing equations of the nonNewtonian fluid with variable viscosity along with energy and nanoparticles are given. The coupled nonlinear differential equations are solved analytically with the help of the homotopy analysis method (HAM)....

Dark matter is estimated to make up ~84% of all normal/baryonic matter, but cannot be directly imaged. Despite the fact that dark observed yet, its influence on motion stars and gas in spiral galaxies have been detected. One way show are rotation curves plots velocity measurements how fast move a galaxy around center mass. According Newton's Law Gravitation, rotational an indication amount visi...

Kaplain-Meier estimates are widely used for plotting survival curves over time, for one or more strata. Graphical display of survival estimates based on a continuous covariate are more problematic. We propose a simple approach to plotting survival estimates at a specified point in time, based on the value of a continuous explanatory variable. This approach allows for the adjustment of survival ...

due to the importance of material classification issue in grinding circuits, the ‎performance of primary and secondary hydrocyclones in grinding circuit of esfordi ‎phosphate plant was investigated by sampling within 7 days from feed, overflow, and ‎underflow‎ of these hydrocyclones. at first, the d80 of above streams samples were calculated by ‎the screening analysis. the results showed ‎that ...

The rotation curves of a sample of 46 low- and high-surface brightness galaxies are considered in the context of Milgrom's modi_ed dynamics (MOND) to test a new interpolating function proposed by Zhao et al. (2010) [1] and compare with the results of simple interpolating function. The predicted rotation curves are calculated from the total baryonic matter based on the B-band surface photometry,...

The recent work “Bringing closure to the plotting position controversy” (Makkonen, 2008a) states the impossibility of a different solution from the classical plotting position proposed by Weibull (1939) and promoted by Gumbel (1958). In this paper, a new and better distribution-free solution is obtained via axiomatic approach. The applicative implications of a comparative study, carried out by ...

introduction the use of cut-outs in electron applicators make changes on output, isodose, and percentage depth dose (pdd) curves. these changes and electron beam dose distribution in the form of three-dimensional (3d) can be measured by gel dosimeters. materials and methods dosimetry was performed with and without a square shield (6×6 cm2 field). the energies were 4, 9, and 16 mev and phantom w...
