A sensitive fluorometric method for the determination of deferiprone (DFP) based on the formation of a luminescent complex with Tb3+ ions in aqueous solutions is reported. The maximum excitation and emission wavelengths were 295 and 545 nm, respectively. The effects of various factors on the luminescence intensity of the system were investigated and optimized, then under the optimum conditions,...
Abstract In this research, a generalized tool life modelling for considering non-stationary cutting conditions was developed . particular, the first time in literature, model conceived predicting of when spindle speed variation SSV , one most effective techniques suppressing regenerative chatter vibrations, is used. The proposed formulation takes into account main parameters and associated to A...
One of the methods increasing efficiency using prestressed reinforcement involves transferring a certain amount longitudinal tensioned from tensile zone in span to upper compressed on support, where it is not fully used ensure bending resistance. More effective may be solution which, due broken outline along length element, pre-stressed tendons are arranged at an angle axis, creating vertical c...
