Fracture failure of super 13Cr can occur in complex and harsh environments such as high temperature, pressure, corrosive gas wells, which damages the economic benefit oil development also poses a great threat to wellbore integrity. Therefore, it is urgent study corrosion mechanism tubing this performed an on-site experimental analysis on failed tubing, employing microarea electrochemical scanni...

We have studied the evolution of the shell structure of nuclei near the neutron drip line in the Relativistic Hartree-Bogoliubov (RHB) theory with the vector self-coupling of ω meson. The experimental data on the shell effects about the waiting-point nucleus 80 Zn are reproduced successfully. It is shown that the shell effects at N = 82 near the r-process path remain strong. A quenching exhibit...

The South Korea Plateau (SKP), a typical submarine plateau, preserves an important tectono-sedimentary evolutionary record and represents major frontier area for petroleum exploration in the East Sea (Sea of Japan). However, its tectonic mechanisms their controls on sedimentary fill are underexplored. Here, we present first integrated tectonostratigraphic framework SKP using reprocessed, two-di...

Rotation-induced time-odd components in the nuclear mean field are analyzed using the Hartree-Fock cranking approach with effective interactions SIII, SkM*, and SkP. Identical dynamical moments J (2) are obtained for pairs of superdeformed bands 151 Tb(2)– 152 Dy(1) and 150 Gd(2)– 151 Tb(1). The corresponding relative alignments strongly depend on which time-odd mean-field terms are taken into ...

Although neural stem cells hold considerable promise for treatment of the injured or degenerating nervous system, their current human sources are embryonic stem cells and fetally derived neural tissue. Here, we asked whether rodent and human skin-derived precursors (SKPs), neural crest-related precursors found in neonatal dermis, represent a source of functional, myelinating Schwann cells. Spec...
