Abstract: A learning solution context is specified in terms of formal and informal learning within zones of interaction. Solution components of purpose/outcome, measurement, technology/infrastructure, resources, and process are specified and selected to align each to the solution context providing an optimal learning solution for a particular client.

Abstract: A process for preparing a form of chenodeoxycholic acid having a melting point of ca. 166.degree. C from the amorphous form of the acid or from the form melting at ca. 120.degree. C. The amorphous or low melting forms of chenodeoxycholic acid, in a suspension in water, are seeded with preprepared crystalline acid of the high melting form and the acid product treated, in suspension, at a temperature of not greater than 85.degree. C to complete the conversion of the chenodeoxycholic acid to the high melting form. Crude chenodeoxycholic acid of the low melting form is purified by a process which involves forming a mixture of the crude acid, methanol, a base and a calcium or strontium salt, separating the precipitated crystalline calcium or strontium chenodeoxycholanate, dissolving the salt in a solution of acetic or propionic acid, diluting the solution with water to precipitate the free acid in purified form and recovering the purified acid.
