Improved Enumeration of Weakly Fluorescent CD4+ T-lymphocytes by Confining Cells in a Spinning Sample Cartridge with a Helical Minichannel

Micromachines, 2020
The CD4 (cluster of differentiation 4) counting method is used to measure the number of CD4+ T-lymphocytes per microliter of blood and to evaluate the timing of the initiation of antiretroviral therapy as well as the effectiveness of treatment in ...

Development and application of model test system for mud pumping in ballasted track subgrade

Yantu gongcheng xuebao, 2022
In order to study the mud pumping mechanism of ballasted track subgrade on the existing lines in China, a physical modelling system which can simulate the cyclic loading-wetting coupling process is developed. The model sample with a diameter of 500 mm is

Equilibrium Position of a Particle in a Microchannel Flow of Newtonian and Power-Law Fluids with an Obstacle

Mathematics, 2023
The equilibrium position yep/H of a particle in a microchannel flow of Newtonian and power-law fluids with an obstacle is numerically studied using the lattice Boltzmann method in the range of the ratio of an obstacle to particle diameter 0.5 ≤ β ≤ 2 ...

Creep-erosion coupling water inrush model of weakly cemented fault rock mass

Meitan xuebao, 2023
In order to investigate the temporal-spatial evolution properties of the water inrush disaster process of weakly cemented fault rock mass, a creep-erosion coupling water inrush model of weakly cemented fault rock mass is established.

Assessment of Mechanisms for Particle Migration in Semi-Solid High Pressure Die Cast Aluminium-Silicon Alloys

Journal of Manufacturing and Materials Processing, 2020
In semi-solid metal high pressure die casting and in conventional high pressure die casting, it is common to find a defect band just below the surface of the component. The formation of these bands is not fully understood.

Second Law Analysis of Nanofluid Flow within a Circular Minichannel Considering Nanoparticle Migration

Entropy, 2016
In the current research, entropy generation for the water–alumina nanofluid flow is studied in a circular minichannel for the laminar regime under constant wall heat flux in order to evaluate irreversibilities arising from friction and heat transfer.

Investigation on Swelling Performance of Oil Sands and Its Impact on Oil Production during SAGD Processes

Energies, 2022
SAGD (Steam Assisted Gravity Drainage) is used in Canadian fields where there are interlayers that impede steam chamber development and thus impede production. Many experiments have been conducted on the effect of interlayers on oil recovery.
