The study evaluates the coag-flocculation efficiency and functional kinetic parameter response to varying pH and dosage of coal washery effluent and ABC respectively. The maximum coag-flocculation performance is recorded at rate constant, K of 3.3333 x 10-3m3/kg.s, dosage of (0.3 and 0.2kg/m3);pH of 2 and coagulation period, τ1/2of 28.1216 s while the minimum is recorded at K of 1.6667 x 10-4m3/kg.s, dosage of 0.2kg/m3, pH of 10 and τ1/2 of 562.365 s. The least value of coag-flocculation efficiency, E (%)>89.00. Simulated and unsimulated values of rate constants Ks and K respectively are in close agreement, validating the concept of perikinetics. The potential of ABC as an effective organic coag-flocculant has been established. The results confirm that theory of rapid coagflocculation holds for the aggregation of coal washery effluent using ABC and at the conditions of the experiment.展开更多

Serum a1-AT levels were significantly higher in patients with PHC than in normal adults (P<0.001). Elevated levels of a1-AT were found in 43% of patients with PHC. No difference was found in a1-AT between patients with benigh liver diseases and health adults (P>0.05). The results indicated that a1-AT is one of the serum markers useful for diagnosing PHC. It is hopeful by using the monoclonal antibody against a1-AT as a new reagent to examine a1-AT on the molocular cytological level.展开更多
