Abstract: Recent experiments respectively performed at Linac Coherent Light Source and at Orion Laser evoke much attention on ionization potential depression (IPD) in dense plasma. In this paper, the validity of six IPD models in the warm dense region is examined, including the ion-sphere (IS) model, the Debye-Hückel (DH) model and t [...] Read more.

Abstract: From a geometric perspective, we proved the following conclusions, that are against mainstream scholars’ viewpoint. (i) Vanishing of the covariant divergence of matter energy­ momentum flux density in entire spacetime is a conservation law of matter energy-momentum. It reads the net increase of matter energy-momentum in any [...] Read more.

Abstract: Nowadays, the world is facing the depletion of developed reserves and exploitation of fields with poor reservoir features. These factors are forcing oil producers to use low-capacity electric centrifugal submersible pump units (ESP) with pumping pressure of over 2,000 m for oil extraction. The use of such ESP in oil product [...] Read more.
