Describes and apparatus designed to generate and detect pulsed ultrasonics in solids and liquids over the frequency range 1-20 MHz. Experiments are suggested for velocity of sound, elastic constant and ultrasonic attenuation measurements on various materials over a wide temperature range. The equipment should be useful for demonstration purposes.…

Describes nuclear teaching experiments and their distribution within the undergraduate curriculum. In addition, sources of information on published nuclear teaching experiments and on the supplier's of nuclear instruments, radiochemical and miscellaneous special materials are identified. Approximate costs for selected nuclear instrument systems…

Attempts to present a methodology for evaluating potential for supervisory positions among a group of individuals labeled disadvantaged, by means of simulation exercises. (Author/DR)

Laser enhanced ionization (LEI) occurs when a tunable dye laser is used to excite a specific atomic population in a flame. Explores the origin of LEI's high sensitivity and identifies possible avenues to higher sensitivity by describing instrument used and experimental procedures and discussing ion formation/detection. (Author/JN)

Discusses developments in electrochemical instrumentation, including the role of computers, measurement/control instruments, present needs and future prospects. Indicates that microprocessors are used primarily for data processing, and that progress depends on noninstrumental factors such as electrode materials. (Author/JN)
