Describes a computer communication course (and its associated laboratory) developed for electrical engineering students at the University of Florida. The course teaches seniors and graduate students the theoretical limits that affect the implementation of serial digital communications and surveys the interface standards, data link protocols, and…

Investigates strategies of 10-year-olds and 14-year-olds in tasks requiring prospective memory. Subjects were instructed to perform activities after waiting 30 minutes. As predicted, strategic time-monitoring occurred more frequently in the home than in the laboratory. Emphasizes the power of the laboratory as a contrasting context for…

Describes the advantages and features of computer-assisted laboratory stations for use in a chemical engineering program. Also describes a typical experiment at such a station: determining the response times of a solid state humidity sensor at various humidity conditions and developing an empirical model for the sensor. (JN)

A laboratory course design to teach the principles of process data acquisition and control using digital computers was developed at Washington University. The structure of the laboratory and course are described. The course outline and list of experiments are included. (JN)

Describes the preparation of two radical systems that are stable at ambient temperatures and give reproducibly well-resolved spectra without careful control of temperature or vacuum line degassing of oxygen. (MLH)

Describes the theory, apparatus, and procedure for an experiment that measures the bimolecular quenching constant for the deactivation of an excited ruthenium ion complex using dissolved oxygen. (MLH)

Describes an experiment in which the reaction rate and equilibrium constant are obtained for the fumarase-catalyzed interconversion of fumaric acid and L-malic acid. (MLH)

Describes an undergraduate chemistry laboratory experiment involving the production of phenol from benzene with the intermediate production of isopropylbenzene and isopropylbenzene hydroperoxide. (SL)

Demonstrates that preexposure to uncorrelated presentations of noises and shocks when rats are not permitted to respond interferes with the acquisition of both conditioned emotional response and signaled punishment suppression. (Author/RK)

Describes an experiment that utilizes the techniques of temperature synthesis, crystallization from a molten salt, oxidation-reduction in a molten salt, powder X-ray diffraction and analysis by high temperature volatilization or a specific ion electrode. (MLH)

Describes an experiment that shows that fluorescence emission intensities are significantly modified by absorption processes and that these effects can be eliminated by positioning the sample cell such that the interrogation region corresponds to the corner of the cell. (MLH)

Demonstrates how to use the area of proton magnetic resonance peaks to distinguish protons in water molecules close to a metal cation from protons in the bulk of the water. (MLH)

Discusses a chemical engineering course which includes laboratory experiments on polymerization, polymer fabrication, and polymer properties. (MLH)

Discusses the dipositive oxidation state of silicon and describes laboratory experiments concerning the synthesis and reactions of silicon difluoride. (MLH)

Describes an experiment in which the student is presented with the problem of selecting a suitable indicator for the determination of the hydroxide in basic copper chromate. (MLH)
