A shrinking core model is presented for the galvanostatic discharge of a metal hydride particle. A quantitative criterion for when the shrinking core can be completely neglected or approximated by a pseudosteady-state solution is presented. The effect of shrinking of the core on the discharge behavior of a metal hydride particle is also studied. © 2000 The Electrochemical Society. S0013-4651(00...

Regression and neural network models of wage determination are constructed where the explanatory variables include detailed information about the impact of school curricula on future earnings. It is established that there are strong nonlinearities and interaction effects present in the relationship between curriculum and earnings. The results have important implications in the context of the hu...

Referring to Figure 1, a system for using a PLL to generate higher frequencies than the input, the VCO oscillates at an angular frequency of ωO. A portion of this signal is fed back to the error detector, via a frequency divider with a ratio 1/N. This divided down frequency is fed to one input of the error detector. The other input in this example is a fixed reference signal. The error detector...

Fungal skin infections are the most common disease worldwide. Superficial mycoses caused by Trichophyton rubrum and T.interdigitale one of leading causes for patients to seek dermatological care. Terbinafine (TRB), acting through squalene epoxidase (SQLE) inhibition, is drug choice curing both species. However, TRB-resistant cases increasing. Between 2013 2021, we examined TRB-sensitivity in 54...
