Discusses major themes and interrelationships common to bioselective potentiometric membrane electrodes including the nature of bioselective electrodes, applications, and future prospects. Includes tables on traditional ion-selective membrane electrodes, nontraditional electrodes, and typical biocatalytic potentiometric electrodes. (Author/JN)

The use of microelectronics and computers in medicine is reviewed, focusing on medical research; medical data collection, storage, retrieval, and manipulation; medical decision making; computed tomography; ultrasonic imaging; role in clinical laboratories; and use as adjuncts for diagnostic tests, monitors of critically-ill patients, and with the…

Presents a description of the world's largest radio/radar antenna, the Areciba Observatory in Puerto Rico. Activities at the observatory are discussed as well as the scientific research in the field of radio astronomy. (SA)

Discusses the role of the Francis Bitter National Magnet Laboratory of the Massachusetts of Technology, and its significance in the world of research. Applications of research on magnetism to medicine are emphasized. (SA)

Reports results of a study for NSF on the scientific instrumentation needs of research universities. Examines current status of scientific instruments in 16 major research universities, six government laboratories, and nine commercial laboratories; and identifies factors that facilitate or impede their acquisition, use, and development. (CS)

Presented are lists of deshielding constants chosen to be easy to remember and to given estimates close enough to measured shifts to allow interpretation of the spectrum of a compound of known structure. (BT)

Provides a survey and a review of earthquake activity and global tectonics from the advancement of the theory of continental drift to the present. Topics include: an identification of the major seismic regions of the earth, seismic measurement techniques, seismic design criteria for buildings, and the prediction of earthquakes. (BT)

Describes a learning project in analytical chemistry in which students are required to select instruments from the manufacturers' literature that would be suitable for a given analytical problem. Several examples are given. (SA)

A description is presented of a semantic differential instrument which evaluates attitude changes. Results are given from the testing of a twenty-five bipolar adjective scale intended to identify descriptors of nutrition education. (Author/SA)

Surveys the state of commerical development of analytical instrumentation as reflected by the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. Includes optical spectroscopy, liquid chromatography, magnetic spectrometers, and x-ray. (Author/MA)

Describes two variations of an air sampler and analyzer that are inexpensive to construct, easy to operate, and designed to be used in an educational program. Variations use vacuum cleaners and aquarium pumps, and white facial tissues serve as filters. Samples of air pollution obtained by this method may be used from early grade school to advanced…

Some of the important modern developments of thin-layer chromatography are introduced. Discussed are the theory and instrumentation of thin-layer chromatography including multidimensional and multimodal techniques. Lists 53 references. (CW)

Describes the function of the various parts of the microscope and their integration in the formation of an optical image. Presents a procedure for setting up a microscope to obtain maximum resolution and contrast for each objective lens at all magnifications. (JRH)

Investigates the effect of movement instruction on beginning instrumentalists' steady beat perception, synchronization, and performance. Finds that a group receiving movement instruction did not perform significantly better than a control group at perception but did perform significantly better at synchronization and performance. Notes low,…

A comparison of 22 students in a traditional curriculum and 70 in a curriculum using speech science instrumentation demonstrated that opportunities to experience research improved attitudes toward and comfort with the research process. Findings support early introduction of scientific method into the communication disorders curriculum. (SK)
