A combined experimental and numerical study on the triaxial and dynamic compression behavior of cemented tailings backfill
(Elsevier Sci Ltd, 2020)
A full understanding of the mechanical response of cemented tailings backfill (CTB) under various loading scenarios is beneficial for mining engineering applications. This study experimentally investigates the stress - - ...
Characterization of early age behavior of cemented paste backfill through the magnitude and frequency spectrum of ultrasonic P-wave
(Elsevier Sci Ltd, 2020)
Cemented paste backfill (CPB) is broadly used for underground backfilling, improving the mechanical performance through the modification of its composition and, therefore, its microstructure and characteristics. in order ...
Effect of mineral admixtures on flow properties of fresh cemented paste backfill: Assessment of time dependency and thixotropy
(Elsevier, 2020)
Cemented paste backfill (CPB), an engineered mix consisting typically of tailings, cement and water, has become a regularly used structural material in most mines worldwide. the performance of the CPB structure is dependent ...
Effect of laminar airflow unit diffuser size on pathogen particle distribution in an operating room
(Taylor & Francis Inc, 2020)
Operating room ventilation is quite important to protect patients from infection risk inside a surgical field. the laminar flow units (LAF) used in these applications contribute to removal of pathogen particles from the ...
Numerical analysis of entropy generation in a square cavity filled with boron-water nanofluid
(Springer Heidelberg, 2020)
The entropy generation and natural convection in a square cavity filled with boron-water nanofluid is numerically investigated under the influence of different nanoparticle volume fractions and buoyancy forces when heated ...
Fluid inclusion and stable isotope constraints (C, O, H) on the Dagbasi Fe-Cu-Zn skarn mineralization (Trabzon, NE Turkey)
(Elsevier, 2020)
The Dagbasi Fe-Cu-Zn skarn mineralization developed along the contact between the block and lens shaped limestones of the Lower Cretaceous Berdiga Formation and the Upper Cretaceous Dagbasi Granitoid. the exoskam-type ...
Silurian to Early Devonian arc magmatism in the western Sakarya Zone (NW Turkey), with inference to the closure of the Rheic Ocean
(Elsevier, 2020)
The Rheic Ocean is the most significant Paleozoic ocean that detached peri-Gondwana terranes from the northern Gondwana margin throughout the closure of the Iapetus Ocean. the suture of the Rheic Ocean spreads from Mexico ...
Melting of the juvenile lower crust in a far-field response to roll-back of the southern Neotethyan oceanic lithosphere: the Oligocene adakitic dacites, NE Turkey
(Elsevier, 2020)
Late Cenozoic tectono-thermal events and associated magmatism in the Sakarya Zone (SZ) are still contested. Although documented in the western part of the SZ, thus far, no magmatic activity has been identified in the eastern ...
Flow boiling characteristics in a novel minichannel with a step on each corner
(Taylor & Francis Inc, 2020)
In the present study, flow boiling in a single minichannel with a longitudinal step on its each corner is studied experimentally. Bubble/flow dynamics, and thus, underlying physical phenomenon is investigated through ...
Rheological properties of cemented paste backfill with alkali-activated slag
(Mdpi, 2020)
This study investigates the time-dependent rheological behavior of cemented paste backfill (CPB) that contains alkali-activated slag (AAS) as a binder. Rheological measurements with the controlled shear strain method have ...
