Kelly, Michael A. – Journal of Chemical Education, 2004
A study of the development of commercial electron spectroscopy of chemical analysis (ESCA) instrumentation over a span of three decades is presented. The field has also been extended significantly by use of synchrotron radiation as a bright X-ray source, which has opened new areas of research in solid-state physics, molecular biology, and many…

Martinez, L. M.; Videa, M.; Mederos, F.; Mesquita, J. – Journal of Chemical Education, 2007
The construction of a new highly-sensitive, computer-interfaced, differential thermal analysis (DTA) device, used for gathering different information about the chemical reactions, is described. The instrument provides a better understanding about the phase transitions, phase diagrams and many more concepts to the students.

DREHER, JOHN J.; LEE, PAO-CH'EN – 1966
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…

Quilter, Shawn M.; Band, Jennie P.; Miller, Gary M. – Journal of Mental Health Counseling, 1999
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…
