Einfluss einer Heckklappe auf die Düsenströmung im Hyperschall
… to the flap of the hypersonic configuration ELAC of the collaborative research center 253. Numerical simulations confirm the obtained improvements concerning the axial thrust coefficient and the rotating thrust vector in the Mach number range between Ma = 1.23 and Ma = 7. Further studies deal …

Diterpenes as models for the study of their effect on neural progenitor cells and on cytochrome p-450 enzymes
… (DPA) and lathyranes with ingol skeleton (ELAC) promote proliferation process in adult neural progenitor cell (NPC) via PKC-activating, thus improving the brain's endogenous neurogenic response to traumatic injury. Occurrence of these compounds on minute amounts on the known sources is a …
