ACTIVE PARTICLES IN GEOMETRICALLY CONFINED VISCOELASTIC FLUIDS

Active particles in geometrically confined viscoelastic fluids

We experimentally study the dynamics of active particles (APs) in a viscoelastic fluid under various geometrical constraints such as flat walls, spherical obstacles and cylindrical cavities.We observe that the main effect of the apple silk sarees confined viscoelastic fluid is to induce an effective repulsion on the APs when moving close to a rigid

Can microprocessor knees reduce the disparity in trips and falls risks between above and below knee prosthesis users?

While all lower limb prosthesis walkers have a high risk of tripping and/or falling, above knee prosthesis users are reported to fall more frequently.Recognising this, engineers designed microprocessor knees (MPK) to help mitigate these risks, but to what extent these devices reduce this disparity between above and below knee users is unclear.A ser

Hybrid wildebeest (Artiodactyla: Bovidae) provide further evidence for shared signatures of admixture in mammalian crania

The genus Connochaetes, Lichtenstein, 1814, contains two extant species, the blue wildebeest final audio sonorous vi (C.taurinus, Burchell, 1823) and the black wildebeest (C.gnou, Zimmermann, 1780).In recent years, forced sympatry in confined areas within South Africa has led to interbreeding between these taxa and to fertile hybrid offspring.Here
