development and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولDifferential distribution of competence for panplacodal and neural crest induction to non-neural and neural ectoderm.
It is still controversial whether cranial placodes and neural crest cells arise from a common precursor at the neural plate border or whether placodes arise from non-neural ectoderm and neural crest from neural ectoderm. Using tissue grafting in embryos of Xenopus laevis, we show here that the competence for induction of neural plate, neural plate border and neural crest markers is confined to ...
متن کاملlockjaw encodes a zebrafish tfap2a required for early neural crest development.
The neural crest is a uniquely vertebrate cell type that gives rise to much of the craniofacial skeleton, pigment cells and peripheral nervous system, yet its specification and diversification during embryogenesis are poorly understood. Zebrafish homozygous for the lockjaw (low) mutation show defects in all of these derivatives and we show that low (allelic with montblanc) encodes a zebrafish t...
متن کاملZebrafish arl6ip1 Is Required for Neural Crest Development during Embryogenesis
BACKGROUND Although the embryonic expression pattern of ADP ribosylation factor-like 6 interacting protein 1 (Arl6ip1) has been reported, its function in neural crest development is unclear. METHODS/PRINCIPAL FINDINGS We found that knockdown of Arl6ip1 caused defective embryonic neural crest derivatives that were particularly severe in craniofacial cartilages. Expressions of the ectodermal pa...
متن کاملMigratory patterns of sympathetic ganglioblasts and other neural crest derivatives in chick embryos.
While it is well established that neural crest cells migrate to give rise to a variety of cell types and tissues, the migratory patterns among individual neural crest derivatives have not been fully worked out. Such knowledge is important not only in relation to the mechanisms of neural crest migration and differentiation, but also in understanding the ontogeny of the PNS. Of special interest i...
