Kinetic calculation results describing the observed nucleation and growth rates of barium sulphate crystals precipitated in an integrated reaction-crystallization process in a barium sulphate-ammonium chloridewater system are presented and analyzed. The scope of experiments included two continuous model DTM-type crystallizers (Draft Tube Magma) with internal circulation of the suspension forced...

Microalgae are emerging as the sustainable key source of green fuels and neutraceuticals. In the current study, a strain of Chlorella pyrenoidosa was isolated, identified and biochemically analyzed. Studies were undertaken to enhance its biomass and lipid productivities for sustainable biodiesel production. Growth was monitored in BG11, BBM, Bristol and Fogg’s medium as cell count, O.D, PCV and...

An isocratic, stability-indicating, reversed-phase high-performance liquid chromatography (RP-HPLC) method was developed for the quantitative determination of doxofylline and terbutaline sulphate, used for the treatment of respiratory problems. The chromatographic separation was achieved on a Zorbax-SB Phenyl 250 × 4.6mm × 5 μm column with the mobile phase consisting of a mixture of 25 mM ammon...
