Flower stalks of Pulsatilla cernua, an early spring herb in north temperate Asia, changed position from erect to pendulous and back to erect during 6-10 d anthesis. We tested three possible explanations for this movement. Our results showed that (1) this movement is unlikely to be a mechanism to attract pollinators or enhance pollen output, because no pollinator preference was observed between ...

In this study, a two-stage methodology based on the energy savings gained by optimal network reconductoring was developed for sizing and allocation of electric vehicle (EV) charging load at residential locations in urban distribution systems. During first stage, Flower Pollination Algorithm (FPA) applied to minimize annual losses radial system through optimum reconductoring. A multi-objective f...
