The impact of pH and ionic strength on the mobility (individual and co-transport) and deposition kinetics of TiO2 and ZnO NPs in porous media was systematically investigated in this study. Packed column experiments were performed over a series of environmentally relevant ionic strengths with both NaCl (0.1-10 mM) and CaCl2 (0.01-0.1mM) solutions and at pH 5, 7, and 9. The transport of TiO2 NPs ...
OBJECTIVES To assess the level of pain intensity at which patients feel the impetus to ask for a breakthrough cancer pain (BTcP) medication, and level of pain intensity at which patients consider they have achieved acceptable pain control after receiving a BTcP medication. METHODS A consecutive sample of patients who were receiving oral morphine equivalents equal to or more than 60 mg daily, ...
the emerging contaminants are commonly derived from municipal, agricultural, and industrialwastewater sources and pathways. these compounds are polar and poorly biodegradable. the dynamicremoval of atenolol from aqueous solutions by activated carbon in fixed bed column systems was investigated. as far as we know, this is the first study reporting the decontamination by adsorption in fixed bed o...
