Describes a computerized experiment in which the student determines the pk of an acid-base indicator from absorption spectra of the indicator at various concentrations. (MLH)

Contains information regarding pollen and human allergies. Lists most common types of pollen, describes pollen morphology, diagrams and apparatus for collecting pollen, and suggests laboratory activities such as pollen counts, pollen concentration, dispersal, and meteorological effects. (CS)

Presents two hydroboration-alkylation sequences, each requiring a three-hour laboratory period, that demonstrate the synthetic utility of the organoboranes. (MLH)

Describes a biochemistry experiment that illustrates the methodology of affinity chromatography by attaching avidin, a glycoprotein in egg white, to a Sepharose matrix in order to bind biotin-containing proteins. (MLH)

Describes the quantitative analysis of a gaseous mixture using peak heights and ratios between the peak heights. (MLH)

Described is a physics experiment in which carbon dioxide cartridges mounted on a wheel with a spark timer can be utilized to measure the energy release of the cartridges. (SL)

The consolidation of the theoretical concepts as well as the use and learning of experimental techniques that are compatible with the technological evolution has been the main goals in Thermodynamics and Heat Transfer and Thermal Systems Laboratories at Escola Politecnica of University of Sao Paulo. The infra-structure and experimental benches in…

This paper proposes an Internet facility that will authentically provide laboratory experiments remotely. Such a facility is brought to the doors of the distance learner to help provide learning that is comparable to that offered for conventional students. The paper describes the development of a prototype remote laboratory system, including…

Discusses the use of a set of experiments to provide undergraduate electrical engineering students with a knowledge of the state of the art in modern coherent optics from an engineering standpoint. (CC)
