Introduction and purpose: Currently, leachate production and its management are major environmental problems associated with the operation of solid waste landfill. Herein, we sought to evaluate the efficiency of combined processes of coagulation and modified activated bentonite with sodium hydroxide as abiosorbent in the final treatment of leachate. Methods: This experimenta...
the removal of fine particles less than 2.5 μm in diameter generated from industrial plantsrepresents a serious challenge in air pollution abatement. these particles can penetrate deeply into the lungs and are difficult to remove by cyclones, electrostatic precipitators, and other conventional separation devices. in this paper, the influence of acoustic waves on removing aerosol particles from ...
heparin is frequently used in different clinical settings to reduce the coagulating ability of the blood. because of probable adverse effects owing to heparin therapy and regarding variability of patients’ responses to heparin, which make it very unreliable, it seems prudent to monitor meticulously its effects on the human body. there are a lot of laboratory tests to watch its effects on the bo...
in this work, ferric coagulation and acid cracking as olive mill wastewater (omw) pretreatments during photocatalysis process were compared in batch recirculation reactor. as ferric ions influence, ferric coagulation has preference over acid cracking. ferric ions influence on intensification of penolic components absorption on tio2 surfacein initial and oxidize organic pollutant during photocat...
Background: During extrinsic coagulation pathway, a complex is developed between factor VII, calcium and tissue factor (a cell membrane lipoprotein that is exposed after cell injury). Factor VII needs calcium and vitamin K for its biologic activation. Coronary artery disease can be induced by increased level and activity of the coagulation factors VII, VIII and IX. In postmenopausal period, est...
The physical process of extracorporeal membrane oxygenation (ECMO) results in derangement of the hemostatic mechanism, which may lead to increased morbidity, secondary to the disease process. The purpose of this study was to evaluate the hematological status of neonates undergoing ECMO therapy, and to evaluate coagulation tests in predicting hemorrhagic risk. Following Institutional Review Boar...
Background and Objectives: Slaughterhouse wastewater contains various and high amounts of organic matter (e.g., proteins, blood, fat, and lard). In order to produce an effluent suitable for stream discharge, chemical coagulation and electrocoagulation techniques have been particularly explored at the laboratory pilot scale for organic compounds removal from slaughterhouse effluent. The purp...
in this study, nf membrane was used for surface water treatment. the rejection of organic material, measured as total organic carbon (toc), by nanofiltration was examined. the effects of application of pre-ozonation and pre-chlorination on toc removal are discussed and their performances are compared with the performances of nanofiltraion system without pretreatment process. in nf, natural orga...
