A precise model has been developed for studying the inBuence of metallic nanoparticles on blood Row through catheterized tapered elastic arteries with radially varying magnetic *** model is solved under the mild stenosis approximation by considering blood as viscous *** influence of different Bow parameters associated with this problem such as Hartmann number,nanoparticle volume fraction,Grashof number and heat source or sink parameter is analyzed by plotting the graphs of the wall shear stress,resistance impedance to blood flow and stream *** inEuence of the radially varying magnetic field on resistance impedance to Bow is analyzed and it is observed that the signiBcantly strong magnetic force tends to increase in resistance.

A new method is demonstrated for solving the electromagnetic scattering problemof a radially inhomogeneous lossless or lossy dielectric cylinder by Fourier series ***-pared with other methods,the method is simpler in numerical calculation and can be used forsolving scattering problems of a cylinder due to an arbitrary incident electromagnetic beam.

The enigmatic charged states Zc(3900), Zc(4020), Zc(4050), Zb(10610), and Zb(10650) are studied within a coupled-channel Schr¨odinger model[1], where radially excited quark-antiquark (qˉq) pairs, with the same angular momenta and isospin as the a1(1260) and b1(1235), are strongly coupled to their Okubo-Zweig-Iizuka - allowed de-cay channels DˉD+ ˉDD and DˉD, or BˉB+ ˉBB and BˉB, in S and D-wave. Poles, matching the experimental mass and width of all the above states, are found by varying only two free parameters.

The aim of this research is the improvement towards the consumption of energy in the field of engineering and industry. The efforts have been paid to the enhancement of heat transmission and cooling process through a nanofluid coating of a nonlinear stretching disc. The combination of Water(H2 O) and multiple walled carbon nanotubes(MWCNT)/single walled carbon nanotubes(SWCNT) have been used as a nanofluid. The spreading of a thin nano-layer with variable thickness over a nonlinear and radially stretching surface has been considered. The estimated results of the problem have been accomplished using the Optimal Homotopy Analysis Method(OHAM). The residual errors of the OHAM method have been shown physically and numerically. The important physical parameters of skin friction and Nusselt number have been calculated and discussed. The other embedding parameters like generalized magnetic parameter, Prantl number, nanofluid volume fraction and Eckert number have been intended and discussed. The obtained results have been compared with the Numerical(ND-Solve) method for both sorts of CNTs. The closed agreement of both methods has been achieved.

With the help of a radially invariant vector field, we derive inequalities of the Hardy kind, with no boundary terms, for W^(1,p) functions on bounded star domains. Our results are not obtainable from the classical inequalities for W_0^(1,p) functions. Unlike in W_0^(1,p),our inequalities admit maximizers that we describe explicitly.
