the removal of organic precursors of disinfection by-products (dbps), i.e. natural organic matter (nom), prior to disinfection is considered as the most effective approach to minimise the formation of dbps. trihalomethanes (thms) as the main group of dbps are categorized and considered to have the potentiality of increasing the rate of liver, kidney and cns adverse effects. this study which pre...

The efficiency of Moringa oleifera (MO) seeds as a natural coagulant in the coagulation/flocculation process, followed by nanofiltration (NF) for the removal of cyanobacterial cells and cyanotoxins is investigated. "Synthetic water" prepared for the tests comprised de-ionized water with an inoculum of microcystis protocystis cells to obtain turbidity within the 50-450 NTU range. Methodology fol...

A plasma protein required for the support of ristocetininduced platelet aggregation was isolated from antihemophilic factor concentrate and radiolabeled with 1251. A double-antibody radioimmunoassay was developed, with use of specific rabbit anti-Vill related antigen serum and goat anti-rabbit globulin. The assay is sensitive, reproducible, and technically simple to perform. Values obtained in ...

Pulp and paper mill effluent is highly polluting and is a subject of great environmental concern. In the present research we studied the removal of chemical oxygen demand (COD) and colour from paper mill effluent, using the coagulation process. A batch coagulation study was conducted using various coagulants such as aluminium chloride (AlCl3), polyaluminium chloride (PAC) and copper sulphate (C...

Using the substrate H-D-Pro-Phe-Arg-p-nitroanilide-HCl, an amidolytic assay was designed to measure prekallikrein in plasma. At a substrate concentration of 1 mM (Km = 0.2 mM), the amidolysis of purified kallikrein at 1 coagulant unit/ml was observed to be 2.47 mumole/min/ml. Conditions for plasma prekallikrein activation were optimized to approach complete activation when compared to the amido...

Recent studies have shown that endothelial protein C receptor (EPCR) polymorphisms and soluble EPCR levels are associated with thrombotic diseases. It is unknown whether membrane EPCR (mEPCR) heterozygosity and/or physiologically elevated sEPCR levels directly impact the hemostatic balance and the outcome of endotoxemia. In these studies, thrombin infusion experiments revealed that EPCR heteroz...

Introduction: The removal of organic precursors of disinfection byproducts (DBPs), i.e. natural organic matter (NOM), prior to disinfection is considered as the most effective approach to minimise the formation of DBPs. Trihalomethanes (THMs) as the main group of DBPs are categorized and considered to have the potentiality of increasing the rate of liver, kidney and CNS adverse effects. Methods...

We evaluated systemic alterations to the blood coagulation system that occur during a coronary thrombotic event. Peripheral blood coagulation in patients with acute coronary thrombosis was compared with that in people with stable coronary artery disease (CAD). Blood coagulation and platelet activation at the microvascular injury site were assessed using immunochemistry in 28 nonanticoagulated p...

The objective of this research was to optimize the coagulation-flocculation process for abattoir wastewater by utilizing a bio-coagulant derived from Carica Papaya seed (CPS). (CPC) extracted using 2M NaCl solution, and carried out bench scale jar test. Applying design expert (13.0.5.0), 23 full factorials with 5 center points, effects three factors: coagulant dosage (X1), pH (X2), temperature ...

This study aims to examine the decomposition method of liquid waste in home industry, especially tofu by using non-thermal plasma and electrocoagulant methods that are environmentally friendly with low energy. In this study, method, electro-coagulant a combination both (electro-coagulant followed method) were used decompose industry. The results showed electrocoagulation was most effective redu...
