Applied Mathematics Letters, 2002 Positive solutions of the system \(u_t=u_{xx}-v^{-p}\), \(v_t=v_{xx}-u^{-q}\), \(p,q>0\), are studied. It is shown that for some choices of the parameters \(p\) and \(q\) there are initial data for which at a time \(t=T\in(0,\infty)\) one component of the solution vanishes at some point while the other stays bounded away from zero.

Precipitation Versus Partitioning Kinetics during the Quenching of Low-Carbon Martensitic Steels
Metals, 2020 Low-carbon, low-alloy steels undergo auto-tempering and carbon partitioning to austenite during quenching to martensite. The microstructures of two such steels quenched at two cooling rates have been evaluated using electron microscopy to characterise ...

The role of quench back in quench protection of a superconducting solenoid [PDF]
Cryogenics, 1984 This report demonstrates the role of quench back in the quench protection of high current density superconducting solenoid magnets with well-coupled shorted secondary circuits. The phenomenon of ‘quench back’ can be used to greatly reduce the size of an external quench protection resistor or even to eliminate the need for an external quench protection ...

Physical Review Letters, 1988 We argue that for ballistic transport through a narrow conductor (of width $W$) a threshold magnetic field exists below which the Hall resistance vanishes. The field is of order $(\frac{h}{e})k_{\mathrm{F}}^{}{}_{}{}^{\ensuremath{-}1}{W}^{\ensuremath{-}3}$, and is reached when the transverse wavelength of quantum edge states becomes comparable to the ...

Journal of Applied Science and EngineeringIn a corrosive environment, it is crucial to increase the hardness and corrosion resistance of mild steel bucket excavators. Making a hard layer of nickel-chromium (NiCr) alloy by the deposition method is one of the many approaches to achieve this.
