In this paper, we study the quenching behavior of solution of a nonlinear parabolic equation with a singular boundary condition. We prove finite-time quenching for the solution. Further, we show that quenching occurs on the boundary under certain conditions. Furthermore, we show that the time derivative blows up at quenching point. Also, we get a lower solution and an upper bound for quenching ...

Several recent advances in turbulent dynamo theory are reviewed. High resolution simulations of small-scale and large-scale dynamo action in periodic domains are compared with each other and contrasted with similar results at low magnetic Prandtl numbers. It is argued that all the different cases show similarities at intermediate length scales. On the other hand, in the presence of helicity of ...

Abstract The physics program of ultra-relativistic heavy-ion collisions at the Large Hadron Collider (LHC) and Relativistic Heavy-Ion (RHIC) has brought a unique insight into hot dense QCD matter created in such collisions, Quark-Gluon Plasma (QGP). Jet quenching, collection medium-induced modifications jets’ internal structure that occur through their development matter, potential to assess ti...

The presence of alloying elements, sometimes in a very small amount, affects mechanical properties one of these elements is Boron. In Aluminum industries, Boron master alloy is widely used as a grain refiner In this research, the production process of Aluminum –Boron master alloy was studied at first then, it was concurrently added to 2024 Aluminum alloy. After rolling and homogenizing the resu...

Quenching of the reversed-field pinch (RFP) dynamo is observed in numerical simulations using current profile control. A novel algorithm employing active feedback of the dynamo field has been utilized. The quasi-steady state achieved represents an important improvement as compared with earlier numerical work and may indicate a direction for the design of future experiments. Both earlier and the...

resonance light scattering (rls) intensity of silver nanoparticles in the presence of sodium dodecylsulphate was quenched on addition of sulfasalzine. the quenching extent was shown to be proportional to the sulfasalazine concentration. effect of different parameters such as ph, volume and kind of buffer, silver nanoparticles concentration, sodium dodecylsulphate (sds) concentration, and waitin...

We present an analytic model of jet quenching, based on the (D)GLV energy loss formalism, to describe the system size dependence of QGPinduced parton absorption in relativistic heavy ion collisions. Numerical simulations of the transverse momentum dependence of jet quenching are given for central Au+Au and Cu+Cu reactions. Low pT dijet correlations are shown to be sensitive to the reappearance ...
