Variable Resolution in Mass Spectrometry

Bulletin (Society for Applied Spectroscopy), 1951
In recent years, more and more attention has been given to the use of variable resolution in the field of mass spectrometry. In this paper will be discussed some of the reasons why variable resolution is valuable, some ways in which variable resolution may be obtained, and some of the actual results of the use of variable resolution.

Systems with Variable Mass

1980
In Newtonian dynamics the mass of each of the particles of a system is considered constant. The variation of the mass of a particle with the velocity is considered in relativistic mechanics and is not involved in the problems considered here.

Attitude Behavior of a Variable Mass Cylinder

Journal of Applied Mechanics, 1995
This paper examines the attitude motion of a cylindrical body with mass loss. It is found that mass variation can have a substantial influence on the behavior of such a system. Specifically, the initial dimensions as well as the manner in which mass loss affects system inertia are found to be key factors in the determination of the characteristics of ...

Quasars in variable mass hypothesis

Journal of Astrophysics and Astronomy, 1997
The variable Mass Hypothesis of conformal gravitation theory of Hoyle-Narlikar is used to develop a model for the anomalous redshift quasar-galaxy associations. It is hypothesised that quasars are born in and ejected from the nuclei of parent galaxies as massless objects and the particle masses in them systematically increase with epoch.

Mechanics of variable mass systems

Journal of the Franklin Institute, 1963
Abstract The equations of linear and angular momentum are derived for any system whose mass varies with time. The equations themselves are rather well known but the derivations are somewhat unique, and the angular momentum equation is generalized so that an arbitrary reference origin can be used.

More about Variable Mass Systems

American Journal of Physics, 1972
Through the use of an example, it is indicated how the subject of variable mass systems may be introduced to even beginning students.

Variability in Bone Mass Measurement

JAMA: The Journal of the American Medical Association, 1993
To the Editor. —We read with great interest the recent article by Recker et al. 1 The authors concluded that gain in bone mass occurs in healthy young women during the third decade of life, with the median gain (expressed as a percentage per decade) ranging from 4.8% (forearm) to 12.5% (total body).
