1. The effects of defaunation of the rumen of cattle on low-protein diets was studied using animals given free access to a basal diet of liquid molasses and 1500 g oaten straw/head per d. These diets induced moderate numbers of protozoa in the rumen. 2. Nonyl phenol ethoxylate (trade name teric GN9) was used for defaunation; 100 g teric GN9 was found to be sufficient to eliminate protozoa from ...

The desorption behavior of cationic-nonionic surfactant mixtures, tetradecyltrimethylammonium chloride (TTAC) and pentadecylethoxylated nonyl phenol (NP-15), at the alumina-water interface was studied. It has been found that while nonionic NP-15 itself does not adsorb at alumina-water interface, it will do so with cationic TTAC preadsorbed at the interface. During the desorption process, howeve...

Series of emulsion lattices having different composition ratios of styrene/butyl acrylate (St/BuA) as base monomers in conjunction with acrylic acid (AA) and/or methacrylic (MAA) were prepared and characterized. The preparation was carried out in industrial scale in semi batch reactor at pH range of 3-5 using potassium persulphate (KPS) as an initiator, sodium luaryl sulphate (SLS) as an emulsi...

1. The effects of defaunation of the rumen of lambs given low-protein-high-energy diets were studied using animals fed ad lib. a basal diet of sugar and oaten chaff which was supplemented with fish meal at various levels. These diets supported relatively large populations of protozoa in the rumen. 2. A nonyl phenol ethoxylate (15 g. Teric GN9:ICI Australian Ltd) given intraruminally, was shown ...

A series of water insoluble poly[(2-ethyl-2-oxazoline)-ran-(2-nonyl-2-oxazoline)] amphiphilic copolymers was synthesized and their solubility properties in the presence of different supramolecular host molecules were investigated. The resulting polymer-cavitand assemblies exhibited a thermoresponsive behavior that could be modulated by variation of the copolymer composition and length. Interest...
