Analysis of Stress-Strain State and Contact Pressures on Surfaces of Kaplan Runner Blade Bearing Bronze Bushes

An analysis of the existing and prospective blade seal designs for Kaplan runners was performed.The selected design type provides the maximum ecological safety for Kaplan runners.A 3D model of runner hub sector with the trunnion, inner and outer bushes of blade moondrop quarks trunnion was generated taking into account the cyclic symmetry of the ru

The intragenus and interspecies quorum-sensing autoinducers exert distinct control over Vibrio cholerae biofilm formation and dispersal.

Vibrio cholerae possesses multiple quorum-sensing (QS) systems that control virulence and biofilm formation among other traits.At low cell densities, when QS autoinducers are absent, V.cholerae forms biofilms.At high read more cell densities, when autoinducers have accumulated, biofilm formation is repressed, and dispersal occurs.Here, we focus on
