Notes: Abstract This paper describes a method to solve large sparse maximum entropy problems with linear equality constraints using Newtons and the conjugate gradient method. A numerical example is given to introduce the reader to possible applications of entropy models and this method. Some experience from large scale problems is also reported.

Notes: The present paper describes a new technique for preparing the surface of polyethylene and polypropylene plastics for the adsorption of heparin. The procedure consists of exposing the plastic surface to a solution of cationic surfactants at a temperature close to the softening temperature of the plastic. The mechanism of adsorption of the anticoagulant of the surfaces is discussed.
