Am. Oil Chem. Soc., 89 (2012), 497–504 ('Optimization of Biodiesel Production Using a Magnetically Stabilized Fluidized Bed Reactor'), http://dx.doi.org/10.1007/s11746-011-1924-7.One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper is not under consideration for publication elsewhere.
