The precise role of the Orr mechanism in transition parallel shear flow is investigated. We found two scenarios, oblique and streak transition, which plays a central triggering transition. In spanwise velocity perturbation amplified with initiates both amplification breakdown, whereas limited only to breakdown at late stage

cytotoxicity evaluation of daphne mucronata (thymelaeaceae) extract and one of its active purified components, using seven different cancerous cell lines, revealed the strong antiproliferative activity of the plant. using flow cytometry technique, it was found that treatment of the most responsive cells (k562) with the plant extract or the active component inhibited the progression of cells thr...

objective: immunotoxins (its) have been developed for the treatment of cancer, and comprise of antibodies linked to toxins. also vascular endothelial growth factor (vegf) plays a key role in tumor angiogenesis, and the blockade of vegf receptor-2 (vegfr2) inhibits angiogenesis and tumor growth. the aim of this study was to produce anti-vegfr2/rpe (pseudomonas exotoxin) 38 it to test its cytotox...

Cavitation and turbulence in a diesel injector nozzle has a great effect on the development and primary breakup of spray. However, the mechanism of the cavitation flow inside the nozzle and its influence on spray characteristics have not been clearly known yet because of the internal nozzle flow complexities. In this paper, a comprehensive numerical simulation is carried out to study the intern...
