This article discusses the Physical Fitness Laboratory at North Carolina State University. (RC)

Describes a system of laboratory instruction in which students attend laboratory when their schedules permit, and all laboratory sections, regardless of course, are overseen by one laboratory instructor. (MLH)

Describes experiments which could be performed on an 1860 rotating table apparatus. (CP)

Discusses the laboratory use of a titration end-point detection that relies on a temperature change rather than a color change. (MLH)

Recommendations are made to ensure that academic laboratories are safe and meet safety standards, instruction and information in laboratory safety are widely available, and that students, teachers, and academic research chemists give high priority to safety and health in their laboratories. (author/BB)

This method uses the cathodic deposition of silver from a cyanide solution in a non-partition cell with stainless steel electrodes. (BB)

Describes Department of Health, Education and Welfare (HEW) proposed guidelines for laboratories using chemical carcinogens. The guidelines are designed to provide protection for laboratory workers and their environment from exposure to all types of carcinogenic agents. (GA)

Describes a laboratory procedure to obtain nuclear magnetic resonance (NMR) values for common organic and inorganic groups. (CP)

A photoelectric on-point detector for Winkler oxygen titrations is described. (MR)

Describes the operating characteristics and cost of chart recorders available in Great Britain. (SL)

Provides contributed physics activities and laboratory techniques. (CP)

The design of vocational laboratories must reflect four major design criteria: (1) work flow and activity relationships; (2) equipment size and orientation requirements; (3) mechanical system requirements; and (4) requirements related to supervision, safety, and control. (Author)

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,…
