We study the application of a recently introduced hierarchical description traffic flow control by driver-assist vehicles to include lane changing dynamics. Lane-dependent feedback strategies are implemented at level and aggregate trends studied means Boltzmann-type equations determining three different hydrodynamics based on switching frequency. System first order macroscopic describing evolut...

Biosorption of acidic dyes using the live fern Azolla filliculoides was studied in a discontinuous system. Dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ?C and pH=7. It was shown that increasing the 23initial concentration of dye and its contact time resulted in decreasing the dye taking quantity by the absorbent. Also, type of dye has an ...

The present study is focused on biodesulfurization of natural gas in a batch culture using active microorganisms. The microorganisms used for the removal of hydrogen sulfide were obtained from a hot spring. The experiments were conducted with mixed gas at operating temperatures of 25 to 45°C with a time interval of 5h. Two kinetic models included Logistic and Monod models in a batch culture wer...

Ni catalysts supported on Nano porous catalysts were prepared by the impregnation method and tested for vapor phase hydrogenation of benzene. The textural and physico-chemical properties of Ni catalysts were characterized by the X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscope and N2 adsorption-desorption analysis. The catalytic evaluation reve...

The kinetic models are fundamental knowledge about biochemical and microbial processes. The object of the work is the kinetic model researching based on the biochemical and microbial mechanisms of cell growth, substrate consumption and product formation. The ethanol biosynthesis process as fuel from renewable resources is the engineering goal. The engineering goal requires the inclusion of the ...
