In this work, we Rompers added Cl, Br, and F atoms to the phosphate-silicate (PHS) molecule using the density functional theory (DFT) approach using a 6-31G basis set and the B3LYP level of theory.Numerous characteristics, including HOMO-LUMO, reduced density gradient (RDG), density of states (DOS), non-covalent interaction (NCI) theory, and molecu

Abstract This paper presents a new way to calculate productivity of five-spot pattern at high water cut stages.In low permeability reservoirs, it is difficult for the reservoir fluid to flow, and the recovery factor is very low.Being based on the non-Darcy flow in low permeability reservoir, taking threshold pressure gradient into consideration, a

Aiming at the problem of deformation and destruction of the overlying roadway of overhead-mining in very thin seam, the research methods of measuring the roadway loosening circle and 3D laser scanner Acetylene to monitor the deformation of the roadway using geological radar are studied.The monitoring results show that the severe deformation of the

In practice, structures of pallet racks are characterized by very wide options of beam-to-column connections.The up to date part of the standard Eurocode 3 considers details for the design of connections.However, experimental determination of the joint properties in steel pallet racks is the most reliable process, since it takes into account Litter

Several practical methods for accelerating the depletion calculation in a GPU-based Monte Carlo Soccer - Goalie - Gloves (MC) code PRAGMA are presented including the multilevel spectral collapse method and the vectorized Chebyshev rational approximation method (CRAM).Since the generation of microscopic reaction rates for each nuclide needed for the
