THE AIM OF THIS STUDY WAS TO IDENTIFY AND SET TONE-REGISTER BOUNDARIES, AND TO DESCRIBE TONAL CONTOURS OF SINGLE WORDS AND COUPLETS IN TERMS OF WHAT GOOD MANDARIN CHINESE SPEAKERS ACTUALLY DO. THE STUDY WAS BASED ON ISOLATED AND COUPLED WORDS OF HIGH LINGUISTIC FREQUENCY, WHICH WERE RECORDED BY 18 PROFESSORS OF MANDARIN CHINESE ON NARROW-BAND…

Manufacturers of instruments and equipment used in the measurement, control, etc., listed alphabetically under product headings. Extensive listing. (LK)

Investigates some of the psychometric characteristics of the results from visual-analogue scales used to measure mental imagery. Reports that the scores from visual-analogue scales are positively related to scores from longer pencil-and-paper measures of mental imagery. Implications and limitations for the use of visual-analogue scales to measure…

The difference between solution and surface properties such as pK(sub a) is illustrated enabling students to understand the differences between nanoscale and macroscopic systems. Details regarding the usage of electrochemical instrumentation, such as a potentiostat, and of the technique such as cyclic voltammetry are given.

The author describes four capacities--interpretation, instrumentation, interaction, and inner direction--that are as important as traditional academic subjects in preparing young adults for college and career success. He suggests how high schools should address each of these capacities. For example, to develop students' capacity for inner…

Discusses the need to encourage increasing numbers of persons to enter analytical chemistry, educate them thoroughly in basic chemical science, and expose them to the most modern methods and instrumentation. Examines some problems and several university's efforts to overcome them. (MVL)

An on-stack transmissometer system, that is designed to provide a precision measurement of the opacity of visible emissions, is described. The sources of error in opacity measurements with regard to recent Environmental Protection Agency emission monitoring requirements and planned specifications are discussed. (Author/BT)

CHAPTER TITLES ARE--(1) INSTRUMENTATIONS--PAST, PRESENT, AND FUTURE, (2) THE OCCUPATIONAL FIELD, (3) WORK ACTIVITIES (DESIGN, FABRICATION, MAINTENANCE, REPAIR, AND SERVICE), (4) TRAINING REQUIREMENTS, AND (5)…

Reprinted in this pamphlet is the fifth annual directory of air pollution control products as compiled in the "Journal of the Air Pollution Control Association" for December, 1971. The 16-page guide lists manufacturers of emission control equipment and air pollution instrumentation under product classifications as derived from McGraw-Hill's "Air…

Discusses: (1) the design of the Fourier Transform-Infrared Spectroscopy (FT-IR) spectrometer; (2) the computation of the spectrum from the interferogram; and (3) the use of apodization. (Part II will discuss advantages of FT-IR over dispersive techniques and show applications of FT-IR to difficult spectroscopic measurements.) (JN)
