Selective Catalytic Reduction for Heavy-duty and Light-duty Vehicles
Whereas previous emission limit values could be met by primary engine control measures, the limits for PM and NOx from heavy duty engines in 2008/09 (Euro V) and diesel passenger cars in 2014/15 (Euro 6) represent a challenge for the developers of diesel engines and vehicles. Due to the thermodynamics of the Diesel combustion process, it is difficult to optimise the combustion process for both ...
متن کاملDriving patterns as a contributing factor to light-duty vehicular emission in the Kumasi metropolis
Exhaust emissions contribute greatly to air pollution, the social cost of which may occur as danger to human health, attracting huge medical expenses, causing absenteeism and hence loss of productivity. These are incentives to reduce exhaust emissions to the barest minimum. Two major cities in Ghana, Accra and Kumasi, are struck by vehicular traffic jams especially during rush-hours and are gra...

متن کاملStatic light scattering to characterize membrane proteins in detergent solution.
Determination of the oligomeric state or the subunit stoichiometry of integral membrane proteins in detergent solution is notoriously difficult, because the amount of detergent (and lipid) associated with the proteins is usually not known. Only two classical methods (sedimentation equilibrium centrifugation and static light scattering) can measure directly the absolute molecular mass of a prote...
