Numerical simulation of the total hip prosthesis under static and dynamic loading (for three activities)
(Techno-Press, 2023)
This study aims to simulate the mechanical behavior of the total prosthesis model of Charnley (CMK3) by the 3D finite element method and to determine the state of the stresses in the femoral components (prosthesis, cement, ...
Progress and prospects of mining with backfill in metal mines in China
(Springer, 2023)
Mining is the foundation of modern industrial development. In the context of the "carbon peaking and carbon neutrality" era, countries have put forward the development strategy of "adhering to the harmonious coexistence ...
Long-term ageing characteristics of cemented paste backfill: Usability of sand as a partial substitute of hazardous tailings
(Elsevier, 2023)
Considering environmental problems caused by sulfidic tailings as a result of long-term ageing as well as inadequacies in their gradations in ensuring the strength needed for cemented paste backfill (CPB), there is a need ...
A Jurassic volcanic passive margin in Iran and Turkey
(Wiley, 2022)
Broadly similar Early to Middle Jurassic stratigraphic sequences including bimodal igneous rocks of the Sanandaj–Sirjan Zone of Iran and the Sakarya Zone of Turkey suggest that these formed in a common tectonic setting in ...
Curing conditions effect on pore structure, compressive strength and elastic modulus of cementitious tailings backfills
(Elsevier, 2023)
As a widespread application in underground metal mines, cementitious tailings backfill (CTB) has a significant implication for recycling dangerous process tailings and enhancing the safety of mining voids. The pore structure ...
Experimental and theoretical examination of the energy performance and CO2 emissions of room air conditioners utilizing natural refrigerant R290 as a substitute for R22
(Springer, 2023)
The purpose of this research is to analyze the performance of an air conditioner that uses natural refrigerant R290 both analytically and experimentally. The feasibility of R290 for R22 air conditioner is examined thoroughly. ...
Microstructure and mechanical behavior of cemented gold/tungsten mine tailings-crushed rock backfill: Effects of rock gradation and content
(Elsevier, 2023)
Without appropriate and responsible waste management in place, the cursory storage of tailings and waste rocks on the surface can cause devastating damage to the planet's ecosystems. To proactively manage or abolish the ...
Optimization of transformer parameters at distribution and power levels with hybrid Grey wolf-whale optimization algorithm
(Elsevier, 2023)
Oil-type transformers (OTT) are used more than dry-type transformers, based on cost in the transmission and distribution of electrical energy. Therefore, this usage density increases the importance of cost in OTT. Weight ...
Novel binder material in geopolymer mortar production: Obsidian stone powder
(Wiley, 2023)
This paper presents the results of mechanical and micro-structural properties of geopolymer mortars with obsidian, ground granulated blast furnace slag, and metakaolin. In this study, 13 different combinations were created ...
Experimental analysis on the impacts of soil deposition and bird droppings on the thermal performance of photovoltaic panels
(Elsevier, 2023)
Photovoltaic (PV) systems are capable of meeting the urgent demand for power production for both domestic and commercial purposes. PV systems possess serious drawbacks as their perfor-mance is heavily influenced by ...
