Uptake of Reactive Black 5 by pumice and walnut activated carbon: Chemistry and adsorption mechanisms
( Korean Society of Industrial Engineering Chemistry , 2014 , Article)The potential of using pumice and walnut wood activated carbon as low-cost adsorbents for the removal of the diazo dye Reactive Black 5 (RB5) from aqueous solutions was investigated. The Langmuir isotherm fit to the data ... -
Classification tree analysis of factors affecting parking choices in Qatar
( Elsevier Ltd , 2015 , Article)Qatar has experienced a significant population growth in the past decade. The growth has been accompanied by an increase in automobile ownership rates leading to parking problems especially in the capital city of Doha. The ... -
Mitigation of railway-induced vibration by using subgrade stiffening
( Elsevier Ltd , 2015 , Article)Railway-induced ground vibration is often associated with sites with soft ground. Stiffening of the subgrade beneath the railway track is one particular measure that has potential to reduce the vibration level at such ... -
Modelling the degradation of vibration characteristics of reinforced concrete beams due to flexural damage
