Abstract Bark extracts, derived from the Brazilian peppertree (Schinus terebinthifolius) were tested on BT549 triple negative breast cancer cells, a model system for invasive, metastatic cancers. Crude prepared with 50% ethanol-50% water solvent, investigated cytotoxicity and effects cell migration in vitro. Extract-treated cells exhibited statistically significant slower velocities than untreated control cells. bark screened at concentration of 3.15mg/mL five independent experiments,...
This work investigates the behavior of a distributed team agents on dynamic task allocation problem. Previous finds that decision making process can effectively assign tasks appropriately to members even when have only local information. We study this problem in environment which move, thus causing neighborhoods change over time. Results indicate higher level adaptation is clearly required environment.
