Abstract: A knowledge management system allocating expert resources, method of allocating expert resources and program product therefor. Information requests are provided over networked devices, e.g., over voice and data networks. Data on experts may be stored in an expert database and data on requesters stored in a requestor database. A pairing unit identifies an appropriate expert matched to each request and requestor. The pairing unit includes a request/requestor characterization unit collecting request/requestor attributes, a matching unit matching request/requestor attributes with an expert, and a routing unit routing each incoming request to a selected matching expert.

Abstract: A blended learning solution is defined by determining degrees of elements in learning zones. The zones are defined by the types of interactions of the learners. Both formal and informal learning is defined for each zone. A specialized circular display is constructed to depict the optimal blended learning solution.

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.
