A two-mass dynamic model of an electric vehicle is considered to obtain analytical dependences describing the gearshift process in a shaft-planetary gearbox. The calculations are based on optimal diagram shifting gears from low high without interruption power flow motor. At stage gear shifting, at which kinematic ratio gearbox changes u1 u2, Lagrange equations second kind used determine time an...

The SCL/TAL-1 gene encodes a basic helix-loop-helix transcription factor that is expressed in multipotent hematopoietic progenitors before lineage commitment. Its expression is maintained during differentiation along erythroid, mast, and megakaryocytic lineages, but is repressed after commitment to nonexpressing lineages. To begin to address the molecular mechanisms underlying this complex patt...

Recently, Brezis, Van Schaftingen and the second author [4] established a new formula for W ? 1 , p norm of function in C c ? ( R N ) . The was obtained by replacing L 2 Gagliardo semi-norm s with weak- quasi-norm setting = This provides characterization such norms, which complements celebrated Bourgain-Brezis-Mironescu (BBM) [1] In this paper, we obtain an analog case 0 particular, present any...

A Silurian regional tectonometamorphic event has been widely recorded by different geochronological methods in the Sierras Pampeanas, NW Argentina and Precordillera. It took place between ca. 445 420 Ma after Hirnantian (late Ordovician) glaciogenic sedimentation. Three domains are recognized. 1) The eastern Pampeanas Puna mainly record focused westward ductile thrusting heating. 2) In westernm...
