Landfill leachates are potential threats for environmental degradation. This study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in Kolkata, India using leachate pollution index. The results of the physico-chemical ...
In the present work, impact of Lewis acid (LA) catalysts BF3, BCl3, and BBr3 on the kinetics andregioselectivity of 1,3-dipolar cycloaddition (1,3-DC) reaction between azidobenzene and acroleinwas theoretically studied using B3LYP/6-31G* level. Our results indicate while the uncatalyzed 1,3-DC reaction under investigation takes place via a non-polar, non-regioselective, and lowasynchronous proc...
Kinin studies were performed in six patients with vasomotor dumping after gastric surgery and in six control patients who had had similar surgical procedures without subsequent dumping. Depletion of the precursor, kininogen, was found in all the patients with dumping and increased free plasma kinin activity in four after a 50-g carbohydrate meal which precipitated an attack. No significant chan...
In Asian developing countries, large amounts of municipal wastes are dumped daily in open dumping sites without proper management. This practice may cause several adverse environmental consequences and increased health risk to local communities. To elucidate contamination by persistent organic pollutants (POPs)--including dichloro-diphenyl-trichloroethane and its metabolites (DDTs), hexachloroc...
BACKGROUND The purposes of this paper were to examine whether patient dumping has occurred under the National Health Insurance and to explore hospital administrators' attitudes toward the practice of patient dumping in Taiwan. METHODS The study subjects were administrators in general hospitals that were accredited by the Taiwan Joint Commission on Hospital Accreditation as medical centers, re...
