A study of selected control variables for a bottom-fed thickener
… three input parameters were studied under three polymeric conditions. The X-ray analysis of underflow refuse samples from two coal preparation plants showed that the samples contained clays of various types. Kaolinite type clay was chosen as the feed material in this investigation. The static …

Analysis of charged polymer effects on recombinant retrovirus-mediated gene transfer success
… hexadimethrine bromide (polybrene) are cationic polymers which are frequently used to enhance the transduction efficiency of recombinant retroviruses in gene therapy experiments. Conversely, chondroitin sulfate proteoglycan is an anionic polymer endogenously present in retrovirus stocks which …

Full scale study of chemically enhanced primary treatment in Riviera de Sao Lourenco, Brazil
… of metal salts and extremely small amounts of an anionic polymer. These additions cause the particulate matter in the wastewater to coagulate and flocculate, thus creating larger particles, which in turn settle at a much faster rate. This thesis looks at the different forms by which CEPT can be …

Analytical separations using packed and open-tubular capillary electrochromatography
… chloride), PDADMAC, was used as the cationic polymer and poly (sodium N-undecanoyl-L-glycinate), poly (L-SUG), was used as the anionic polymer for the construction of the PEM coating. The performance of the modified capillaries as a separation medium was evaluated by use of seven …

Pretreatment and biodegradation of wastewater from a textile dyeing and finishing industry
… reactors. In regard to pretreatment with various polymers, coagulation with a blend of inorganic aluminum and a polyamine (AL220, Polymer Systems, Inc.) produced the most economical and efficient results. Subsequent addition of an anionic polymer improved the settling characteristics of the …

Conditioning and Dewatering Behavior of ATAD Sludges
… for digestion of sludge. However the large polymer costs associated with dewatering these sludges has made the use of this technology unfavorable. Several studies have been conducted in the past which have looked into the mechanism leading to such a poor dewatering of sludge. Some of these …

Polymer Supported Lipid Bilayer Membranes for the Integration of Transmembrane Proteins
… lipids as well as synthetic lipids on a set of polymer cushions consisting of alternating maleic acid copolymers. Maleic acid copolymers provide a versatile platform to adjust the physico-chemical behaviour by the choice of the comonomer unit. The formation of sLBMs was triggered by a transient …

DEVELOPMENT AND OPTMIZATION OF POLYELECTROLYTE POLYMER BRUSHES FOR THE FRACTIONATION OF PEPTIDE AND PROTEIN MIXTURES PRIOR TO MALDI MASS SPECTROMETRY ANALYSIS
… is the synthesis, development and application of polymer brushes for the fractionation of complex mixtures of peptides and digested proteins prior to MALDI-MS analysis. Even though MALDI-MS analysis is increasingly used in proteomic applications, this method of analysis suffers loss of performance …

Rational Development of New Inhibitors of Lipoteichoic Acid Synthase
… as a potential anti-bacterial target. LTA is an anionic polymer found on the cell envelope of Gram-positive bacteria. It comprises of repeating units of glycerol-phosphate (GroP) and is important for bacterial cell physiology and virulence. For example, it is critically involved in regulating ion …
