The effect of petrochemical industry wastewater composition on the activated sludge microflora
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2006)
In this study, the effect of wastewater composition on the activated sludge microflora has been evaluated. Wastewater samples from the aeration tank of a petrochemical industry wastewater treatment plant were taken and ...
Interband absorption and exciton binding energy in an inverse parabolic quantum well under the magnetic field
(ELSEVIER SCIENCE BV, 2007)
We have investigated the effects of the magnetic field which is applied perpendicular to the growth direction of the well on the interband absorption and on the binding energy of the excitons in an GaAs/Ga1-xAlxAs inverse ...
Soluble microbial product formation in biological systems
