ABSTRACT C ii line intensity mapping (LIM) is a potential technique to probe the early galaxies from Epoch of Reionization (EoR). Several experiments e.g. CONCERTO, TIME, CCAT-p are underway map LIM signal fluctuations EoR, enabling us estimate power-spectrum and × 21-cm cross-power spectrum. The observed will have its time evolution embedded in it along sight due finite traveltime origin obser...

Abstract In recent years, silica-based polymer nanofluids (NFs) have attracted more and attention because they can enhance temperature salt tolerance. This study summarized the research progress prospects of NFs in enhanced oil recovery (EOR). First, synthesis method effect on were studied. Research rheology, wettability, viscoelasticity, interfacial tension, adsorption, porous media flow, emul...

Fracture reservoirs contain most of the oil reserves of the Middle East. Such reservoirs are poorly understood and recovery from fractured reservoirs is typically lower than those from conventional reservoirs. Many efforts have been made to enhance the recovery and production potential of these reservoirs. Fractured reservoirs with high matrix porosity and low matrix permeability need a seconda...

Abstract Flue gas flooding is one of the important technologies to improve oil recovery and achieve greenhouse storage. In order study multicomponent flue storage capacity enhanced (EOR) performance water-alternating (flue gas–WAG) injection after continuous waterflooding in an reservoir, a long core system was built. The experimental results showed that factor gas–WAG increased by 21.25% could...

Direct ethanol fuel cells have broad application prospects, but there are still some issues such as slow oxidation kinetics and poisoning effects of intermediates in the anodic reduction reaction (EOR). Herein, a series few-layer Ag-coated ordered mesoporous Pt nanocrystals ([email protected]) with different Ag shell thicknesses prepared by combining hard templating situ methods. Benefiting fro...

Introduction Clinical Competency Committees (CCC) require reliable, objective data to inform decisions regarding assignment of milestone proficiency levels, which must be reported to the Accreditation Council for Graduate Medical Education. After the development of two new assessment methods, the end-of-shift (EOS) assessment and the end-of-rotation (EOR) assessment, we sought to evaluate their...
