This study was conducted to enhance the tensile bond strengths of resin cements zirconia ceramics. Fifty-six ceramic specimens (Cercon Base) and twenty-eight silica-based (GN-1, GN-1 Ceramic Block) were air-abraded using alumina. Thereafter, divided into two subgroups 28 each according surface pretreatment; no pretreatment (Zr); internal coating technique (INT). For INT, coated by fusing ceramics Ceram Kiss). surfaces conditioned with/without a silane coupling agent followed bonding with one...
Abstract Many operators commit to reducing their operation's carbon dioxide (CO2 emissions. According McKinsey & Company (2020)(1), well drilling and extraction processes contribute 8% of the Scope 1 emissions in oil gas industry. Rig site activities generate one-third overall footprint for construction process. A process consists hundreds tasks ranging from spud rig release. Along way, many different types equipment are used. To minimize emissions, we need analyze how power is used it...
• Thermal evolution does not significantly modify the δ 15 N of bulk rock and kerogen. The sil was slightly lower than ker sediments in YF. obviously QF. Organic inorganic nitrogen isotope values are sensitive to redox conditions. Comprehensive biogeochemical cycle has been reconstructed for representative lacustrine organic-rich sedimentary China, namely Triassic Yanchang Formation (YF, 199–230 Ma) Ordos Cretaceous Qingshankou (QF, 86–92 Songliao basins, by evaluating organic isotopic...
In this paper, a novel CrFeNiB0.03Si0.03 medium entropy alloy (MEA) coating was developed by utilizing Ni-base powder NiBSi in place of pure Ni through laser direct energy deposition (LDED) technology. The study explores the improvement wear and corrosion resistance CrFeNi MEA coatings incorporating B Si elements. results show that addition element generates Cr Fe boride phases, while solidly dissolves FCC phase. Compared to MEA, exhibits doubled microhardness reaching 403 HV0.2 reduced rate...
A novel self-sustaining mechanism is proposed for large-scale helical structures in compressible turbulent flows. The existence of two channels subgrid-scale and viscosity terms helicity evolution confirmed the first time, through selecting a physical definition turbulence. Under influence fluid element expansion, it found that generated at small scales via second-channel viscosity, inverse cross-scale transfers inertial flux. Together, they form self-induced mechanism, which provides...
To analyse the variation of species abundance distribution (SAD) patterns with scale, and consider its formation mechanism ecological process in alpine meadow eastern Qinghai–Tibet Plateau China, study areas were established, nine permanent plots randomly selected, 72 quadrats investigated. Four diversity indices including richness, Margalef, Shannon–Wiener Simpson relative importance values to quantify community assembly biodiversity. Species accumulation curves used describe SADs meadow,...
In this paper, CrFeNi medium entropy alloy (MEA) was prepared by laser melting deposition technology. Then Ni-base powder NiBSi used to replace pure Ni prepare a new cobalt-free CrFeNiB0.03Si0.03 MEA. The effects of B and Si elements on microstructure, microhardness, wear resistance corrosion MEA coating were studied. results show that the addition element generates Cr Fe boride phases. front solid-liquid interface in solidification process, atom is discharged, which plays role reducing...
