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...

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...

The application in this hospital of alternating current for electro-convulsive therapy (E.C.T.) and electronarcbsis in certain mental disturhances afforded the opportunity of investigating the effects of this form of therapy on some of the components of the hlood. Schiitz (1942) ohserved in vitro a delayed coagulation of blood following application of a weak direct current. Brecht and Kummer (1...

Background: Hemophilia B is a bleeding disorder with a recessive X-linked inheritance pattern, in which the infected individuals have low levels of factor IX in their plasma. Affected individuals may have bleeding episodes after trauma or spontaneously considering the plasma level of factor IX. In order to prevent these episodes and to control bleeding, they should use coagulation factor concen...

the purpose of this study is to investigate the performance and efficiency of moringa seeds from different sources on turbidity. a protein analysis test was done for each source; then two different methods of extraction were compared to examine the coagulation activity for the moringa's active ingredient. the results of sodium chloride (naci) extraction in comparison to distilled water ext...

The impact of coagulant type and dosage on the clarity, zeta potential, floc size, structure a coal slurry suspension was investigated. results showed that critical coagulation concentrations trivalent ions are 0.81 mM 0.018 for coal–coal coal–kaolinite, respectively, which lower than those divalent ions. initial settling more affected by AlCl3 FeCl3 MgCl2 CaCl2, while supernatant turbidity sig...
