    Notes: Abstract This report describes our data regarding repeated injection sclerotherapy using a newly designed over-tube. We treated 17 consecutive patients with esophageal varices, (3 acute, 6 elective and 8 prophylactic). An intravariceal injection of 5 per cent ethanolamine oleate was administered, using a newly designed transparent over-tube containing a second lumen for a flexible injection needle. This over-tube provides an easier, safer, shorter-in-time method of sclerosing esophageal varices. One of the 17 patients died as a result of liver failure associated with advanced cirrhosis and a concomitant hepatoma. Eradication of esophageal varices was attained in the remaining 16 patients, after an average of 5.0 injections over an average period of 5.8 weeks (range: 3–7 injections during 3–11 weeks). No complications, such as esophageal perforation or aspiration pneumonia were encountered. Recurrent variceal bleeding has not occurred during the 9 months follow-up.

    Notes: An experimental study of semi-continuous emulsion copolymerization of acrylonitrile (AN) and styrene (ST) was carried cut with an isothermal stirred vessel. Continuous addition of monomer emulsion (ME) was inserted between preliminary and finishing batch operations. A mathematical model to simulate the experimental results was also developed with a particular attention on the partition of hydrophilic AN between the aqueous and organic phases. The result of simulation was quite satisfactory even though the approximate rate expressions proposed by Szabo and Nauman (1) were employed.

    Notes: A computer modeling concept was developed to deal with multicomponent emulsion copolymerization systems. Based on the model, a simulating program called NSBEC (n-component, semibatch emulsion copolymerization) was prepared., NSBEC is capable of carrying out a variety of operations involving any number of monomers with different modes of ingredient feed. In this paper, first the basic concept of the model is explained, then several applications to the actual experimental systems (e.g., acrylonitrile-vinylidene chloride, vinyl acetate-butyl acrylate, and methyl methacrylate-butyl acrylate) are discussed. Finally, the probable control of copolymer composition by means of the semibatch operation based on NSBEC is proposed. The authors expect that use of NSBEC can substantially reduce the number of experimental runs previously required to describe the system.
