  • Some limitations to the success of the Low-Cost Carrier business model in India

    Despite the growth in market share of Indian Low-Cost Carriers (LCCs), there are certain factors inhibiting the success of the LCC business model in India. This paper argues that the success of the LCC business model in India is limited by three exogenous factors – the lack of the concept of secondary airports, the route dispersal guidelines, and the excessively high costs of Aircraft Turbine ...

  • Effect of pH on nitrate and selenate reduction in flue gas desulfurization brine using the H2-based membrane biofilm reactor (MBfR)

    Increased tightening of air regulations is leading more electric utilities to install flue gas desulfurization (FGD) systems. These systems produce brine containing high concentrations of nitrate, nitrite, and selenate which must be removed before discharge. The H2-based membrane biofilm reactor (MBfR) was shown to consistently remove nitrate, nitrite, and selenate at high efficiencies. The ...
