Directed migration of groups of cells is a critical aspect of tissue morphogenesis that ensures proper tissue organization and, consequently, function. Cells moving in groups, unlike single cells, must coordinate their migratory behavior to maintain tissue integrity. During directed migration, cells are guided by a combination of mechanical and chemical cues presented by neighboring cells and t...

This paper reviews the summary and analysis of special technical safety schemes for hazardous ultrahazardous activities, supported by housing scaffolding, installation, dismantling outer wall attached tower crane, deep foundation pit with supporting structure, municipal bridge box girder formwork support, as well grooved Larsen steel sheet pile, which are commonly seen in recent years, so to en...

Low-cost, lightweight, and easily available Fresnel lenses are a more alluring choice for solar laser power production, when compared to the costly complex heliostat-parabolic mirror systems. Therefore, seven-rod head was designed numerically studied enhance efficiency in TEM00-mode employing six with 10 m2 total collection area concentration of sunlight. Six folding mirrors redirected rays tow...

We investigate subcritical resonant heat transfer in a heated periodic grooved channel by modulating the flow with an oscillation of random amplitude. This excitation effectively destabilizes the flow at relatively low Reynolds number and establishes strong communication between the grooved flow and the Tollmien–Schlichting channel waves, as revealed by various statistical quantities we analyse...

Surface wetting is an important phenomenon in many industrial processes including microand nanofluidics. The wetting characteristics depend on the surface tension forces at the three-phase contact line and can be altered by introducing patterned groove structures. This study investigates the effect of the grooves on the transition in the wetting behavior between the Cassie to Wenzel regimes. Th...

One of the main parameters high-quality sowing agricultural seeds is their uniform distribution along length, which mainly influenced by unit. In present work, grain crops using a coil seeding unit considered as an object research. As subject research, dependences uniformity seed length furrow on non-uniformity specific working volume coil, rotation frequency blower pneumatic seeder and rate ar...
