Viral breakthrough is a recognized response pattern to interferon-based antiviral therapy in patients with chronic hepatitis C virus (HCV) infection. The emergence of drug-resistant HCV quasispecies variants is assumed to be a major mechanism responsible for viral breakthrough. By using a long reverse transcription-PCR protocol recently developed in our lab, multiple nearly full-length HCV quas...

conclusions results indicated that annular fluidized bed reactor’s adsorbers are useful techniques for vocs adsorption. comparison of two particle ranges indicates that in all concentrations and all flow rates of the experiments, smaller particle size adsorption are better. in superficial velocity above the minimum fluidization velocity, pressure drop of fluidized beds are less than the pressur...

Active carbon (surface area, 1250 m/g) was used to study vapor breakthrough behavior of sulphur mustard (2, 2’dichlorodiethyl sulphide). Effect of length of carbon bed on vapor breakthrough time has been examined. Rate constant (k v ) is found to increase while kinetic saturation capacity (W e ) is invariable with increase in airflow rate. Both k v and W e decrease with the increase of temperat...
