Abstract In this paper, the Cauchy problem for one-dimensional compressible isentropic magnetohydrodynamic (MHD) equations with no vacuum at infinity is considered, but initial can be permitted inside region. By deriving a priori ν (resistivity coefficient)-independent estimates, we establish non-resistive limit of global strong solutions large data. Moreover, as by-product, well-posedness resi...

We present a dynamic deontic model for the interpretation of imperative sentences in terms of Obligation (O) and Permission (P). Under the view that imperatives prescribe actions and unlike the so-called “standard solution” (Huntley, 1984) these operators act over actions rather that over statements. Then by distinguishing obligatory from non obligatory actions we tackle the paradox of Free Cho...

We show generalized Galileons -- a particular subclass of Horndeski gravity arise from consistent Kaluza-Klein reduction the low-energy effective action heterotic string theory to first order in $\alpha'$. This suggests theories have string-theoretic origin. The form Galileonic terms is precisely fixed by parameters embedding spacetime, so that only specific subset permitted theory. A novel lim...

In the present study, a simple electrochemical sensor for trace determination of Hg(II) ions in aqueous solutions was introduced. The proposed sensor was designed by incorporation of the 4-methyl-piperidine-carbodithioate capped gold nanoparticles (GNPs) into the carbon paste electrode (CPE), which provides a remarkably improved sensitivity for stripping voltammetric determination of Hg(II). Di...
