Described is a modified Fehling test and a modified corrected Benedict test. (RH)

Discusses features of experiments (conducted during 1980-81 in the University of Edinburgh's third-year chemical engineering laboratory) which might make them attractive for wider use. Experiments focus on convective mass and heat transfer, diffusion, heat transfer to a jet, and adiabatic batch reactors. (JN)

Discusses the role of dogs in research, considering their use in studies related to: behavior; aging; anesthesia; gastrointestinal surgery; the brain; organ transplants; radiobiology; trauma and shock; arterial diseases; hemophelia; ophthalmology; diabetes; nutrition; cancer; lupus; cyclic neutropenia; thyroiditis; hepatitis; skeletal system,…

Discusses a National Research Council report which summarizes what laboratories need to know about Environmental Protection Agency and Department of Transportation regulations that apply to laboratory waste. The report provides guidelines for establishing and operating waste management systems for laboratories and gives specific advice on waste…

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)

Relates two experiments in a physics lab that contain percentage errors. (HOD)

Determined whether improved ventilation and use of "formaldehyde-free" biological specimens could reduce the levels of formaldehyde in air to which students and faculty would be exposed. Both methods were found to be effective in reducing formaldehyde levels in air. (JN)

Provides additional recommendations as the Health and Safety at Work Act of 1974 applies to the storage of flammable liquids, provision of safety equipment, responsibility for technicians and faulty apparatus. (GS)

Discusses what can occur in a laboratory if a cylinder valve is separated from a compressed gas cylinder. (MLH)

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)

This paper discusses the risk assessment associated with microbiology instruction based on grade level, general control measures, appropriate activities for middle school and high school students, the preparation and sterilization of equipment, and safe handling techniques. Appended are instructions and figures on making wire loops and the…

Describes the foreign language program and the language laboratory at the University of Hawaii. (RK)

Circuit design to solve the problem of impedance mismatch between output and input jacks in language laboratory equipment. (RL)

Describes methods and procedures for killing, preserving, mounting, and displaying insects. (JR)

Three programs of individualized instruction in a mathematics laboratory for the community college student are described. Problems and advantages of the programs, including costs; student dropout rate; teacher role; design, operation and management of the laboratory, and grading are discussed. (DT)
