Ferrite Ceramics at Microwave Frequencies

January 1, 2001
Author(s)
Richard G. Geyer
Ferrite ceramics are widely used in microwave devices to control transmission path, frequency, amplitude, and phase of microwave signals. Accurate dielectric and magnetic property measurements at the operational frequency and temperature ranges are needed

Force Distributions Near the Jamming and Glass Transitions

January 1, 2001
Author(s)
C S. O'Hern, Stephen A. Langer, A J. Liu, S R. Nagel
We measure the distributions of interparticle normal forces P(F) near the glass transition in supercooled liquids and near the jamming transition in foams and compare them to those obtained in recent experiments on static granular packings. We find that

Fundamental Constants and the Hydrogen Atom

January 1, 2001
Author(s)
Peter J. Mohr, Barry N. Taylor
A review is given of the latest adjustment of the values of the fundamental constants. The new values are recommended by the Committee on Data for Science and Technology (CODATA) for international use. Most of the fundamental constants are obtained by the

Fundamentals of Mass Spectrometry of Organic Compounds

January 1, 2001
Author(s)
Anzor I. Mikaia, Vladimir G. Zaikin, Alexey V. Varlamov, Nikolay A. Prostakov
The book is about mass spectrometry, design of instruments, theoretical aspects and methodological approaches, includes exercises. Portions of the book developed from lecture and laboratory material used presenting a course in organic mass spectrometry at

Future Voltage Metrology at NIST

January 1, 2001
Author(s)
Yi-hua D. Tang, June E. Sims, Michael H. Kelley
Presently NIST uses a voltage calibration path to maintain the U.S. legal volt and provide for the dissemination of an internationally consistent, accurate, reproducible and traceable voltage standard, tied to the SI units. Potential improvements and
