Industrial purification of biomolecules is commonly based on a sequence of chromatographic processes, which are adapted slightly to new target components, as the time to market is crucial. To improve time and material efficiency, modeling is increasingly used to determine optimal operating conditions, thus providing new challenges for current and…

Summarizes the capabilities of a computer program related to forest fertilization. Provides a description of input parameters, some sample exercises, software specifications, and availability information. Additional references are listed. (Author/RT)

Presents a computer program for use in teaching ion speciation in soil solutions. Provides information on the structure of the program, execution, and software specifications. The program estimates concentrations of ion pairs, hydrolytic species, metal-organic complexes, and free ions in solutions. (Author/RT)

Describes how computer graphic methods can be used in teaching structural geology. Describes the design of a graphics workstation for the Apple microcomputer. Includes a listing of commands used with software to plot structures in a digitized form. Argues for the establishment of computer laboratories for structural geology classes. (TW)

Courseware was developed to facilitate knowledge transfer between lecture and laboratory for general chemistry at the University of Notre Dame (Indiana). One project uses a tutorial strategy. Another uses tool-based courseware for modeling and manipulation of simulated representations of chemical systems; worksheets guide student use of courseware…
