Selective flocculation has long been suggested as a method for the treatment of ultra-fine particles typical of which are those produced in a de-sliming process ahead of flotation. In this paper the results of the coal de-mineralization, using synthetic polyacrylamide polymers, are presented. A prescreening test on the suitability of the polymers using Run-Of-Mine (R.O.M.) coal and artificial m...

The effect of xanthan gum (XG) addition on physicochemical properties of 2wt% whey protein isolate (WPI) stabilized oil-in-water (O/W) emulsions containing 20% v/v menhaden oil was investigated by measuring droplet size, viscosity, microstructure, creaming profile and oxidative stability. In fresh emulsions, addition of XG at different concentrations did not show any significant effect on the s...

Prolonged or permanent impairment of liver function is now known to occur in a variable proportion of patients following an attack of infectious hepatitis or serum jaundice (1-11). However, the incidence of this chronic hepatic disease is not well established because of the difficulty in correlating symptomatology with the available liver function tests or with liver biopsy (12-15). Of the mean...

The processes of coagulation and flocculation using high molecular weight long-chain polymers were applied to treat mine water having fine flocs of which about 93% of the total mass was less than 3.02 microm, representing the size distribution of fine particles. Six different combinations of acryl-type anionic flocculants and polyamine-type cationic coagulants were selected to conduct kinetic t...

A radiological study o f the small intestine o f 17 untreated patients in the acute phase ofschistosomiasis was performed. Twelve patients (70% o f total) had alterations: nine had clear-cut thickening o f the duodenal and jejunal folds, one flocculation, one fragmentation and one thickening o f mucosae, flocculation and fragmentation o f the barium column. There was no correlation o f the gast...

In this work attempts were made to evaluate K+-SDS and hydrocolloid polymer-SDS interactions in flocculation of megestrol acetate dispersions to enhance their stability as a part of suspension formulation. Different dispersions of micronized megestrol acetate and SDS were prepared. KCl and KH2PO4 and their corresponding sodium salts were added to the dispersions and the preparations were evalua...

An outline of preliminary investigations designed to eliminate discrepancies in the results of tetanus antitoxin titrations. 5. Preliminary reports on a proposed international standard antipoliomyelitis convalescent serum. 6. A description of a simple method for th...
