Fine Tuning Cell Migration by a Disintegrin and Metalloproteinases [PDF]
Mediators of Inflammation, 2017 Cell migration is an instrumental process involved in organ development, tissue homeostasis, and various physiological processes and also in numerous pathologies. Both basic cell migration and migration towards chemotactic stimulus consist of changes in cell polarity and cytoskeletal rearrangement, cell detachment from, invasion through, and ...

Modeling of Fine Migration in a Porous Medium [PDF]
MATEC Web of Conferences, 2016 The structure of underground waters and water permeability of rocks must be taken into account when choosing the location of construction objects, the design of tunnels, hydraulic and underground structures. The model of filtration for suspension in solid porous medium during its displacement with clean water is considered. The numerical calculation of

Permeability Decline by Clay Fines Migration around a Low‐Salinity Fluid Injection Well
Ground Water, 2021 Migration of clay fines can be a concern when less saline fluids are injected into brine‐saturated sandstone formations containing clays. If the salinity near fluid injection wells decreases below a critical value, the clay fines near the injection may ...

Application of silica nanofluid to control initiation of fines migration
Petroleum Exploration and Development, 2017 : Core flooding experiment was carried out through SiO2 nanofluid, which was used to change the surface properties of the pore walls, improve the attractive force between fines and pores walls against the hydrodynamic repulsive force in order to increase
