Nine applications of the ordinary language laboratory to the training of simultaneous translators. Functional and technical descriptions of each application are given. These modes of interpretation practice in a university setting substitute for the more sophisticated facilities used by major professional schools. (AMH)

A planetarium, star projector, and projector stand all which can be built for $30 are pictured. Classroom activities involving the materials are described. (CP)

Presents an apparatus for demonstrating two-dimensional random motion suitable for illustrating molecular phenomena. Three specific uses are presented. (SL)

Presents results of a trend survey of the present and planned use of electrical and electronic instruments. Microprocessors were found to have the highest predicted growth rate of all instruments included in the survey. (SL)

Presented is the development of a simulation model of the facultative water transfer mechanism of the mammalian kidney. Discussion topics include simulation philosophy, simulation facilities, the model, and programming the model as a teaching aid. Graphs illustrate typical program displays. A listing of references concludes the article. (MA)

Contains contributed suggestions for laboratory equipment, chemistry activities, and explanations of chemical reactions. (CP)

Discusses four different methods for measuring self-inductance based on the definition of inductance, the alternative definition, phase difference and LC resonance. Provides circuit diagrams and typical oscilloscope traces. (YP)

Describes a soap film demonstration apparatus. Presents information on the construction of the apparatus and methods for thin-film demonstrations. (YP)

Describes the construction of an inexpensive apparatus for separating proteins by polyacrylamide gel electrolysis in the presence of sodium dodecyl sulphate. (TW)

Elements of the development of a robotics and automation laboratory are discussed. These include the benefits of upgrading current staff, ways to achieve this staff development, formation of a robotics factory automation committee, topics to be taught with a robot, elements of a laboratory, laboratory funding, and design safety. (CT)

Describes a solid etalon Fabry-Perot interferometer, discussing free spectral range, instrumental finesse, and temperature effects. Provides schematic of temperature control/display circuit. Explains use of 100 millimeter camera lens and 10 power micrometer eyepiece for resolving rings and measure diameters. (JM)

Discusses the use of an external analog-digital converter to use a computer as a storage oscilloscope. Provides program listings for use as a unipolar or bipolar voltmeter and storage oscilloscope. Schematics and component list are included. (JM)

Describes two computer programs for use in process design courses: an easy-to-use equipment cost estimation program based on latest cost correlations available and an economic evaluation program which calculates two profitability indices. Comparisons between programed and hand-calculated results are included. (JM)

This article contains suggestions for introducing the scientific concept of matter and demonstration acids and bases using low-cost, collectible supplies. Sample questions and experiments are listed to help students explore these ideas. A list of household supplies to be used in the experiments is given. (DF)

Previously described a class experiment which employs the hydraulic analog to represent systems of first order reactions in batch reactors. The hydraulic experiments are extended to represent reaction systems with nonlinear systems. (JN)
