Recently, increasing evidence indicates that genetic defects observed in patient somatic cells could be erased and/or alleviated by direct reprogramming toward pluripotency and recapitulated upon directed differentiation to specific cell lineages...
متن کاملThe Study of Energy Loss in Stepped- Labyrinth Spillways
A ‘spillway’ is a structure used to provide the controlled release of flood water from upstream into downstream area of a dam. As an important component of every dam, a spillway should be constructed strongly, reliably and efficiently to be used at any moment. Labyrinth and stepped spillways are presented as appropriate modifications to those spillways hardly capable of managing the maximum pot...
