Magneto-acoustic resonance in a non-uniform current carrying plasma column

The forced radial magneto-acoustic oscillations in a plasma column with nonuniform mass density and temperature are investigated. It turns out that the oscillations have a resonant character similar to that of the magneto-acoustic oscillations in a uniform plasma column. The properties of the axial and azimuthal components of the oscillating magnetic field are discussed in detai

Magnetohydrodynamic waves in a non-uniform current-carrying plasma column

An effect of an axial current on the propagation of low-frequency axisymmetric magnetohydroclynamic waves in a radially non-uniform plasma column was investigated theoretically and experimentally. It was found that the axial current and the density gradient cause a coupling between the torsional and compressional wave

Competition vs. Profitability

Corporate cultural emphasis on long-term competitiveness as opposed to shorter-term profitability is evaluated in terms of effectiveness in achieving higher profit margins, real profitability, and survival in the long term. Competitive orientation continues to have adverse impact even with a lag of four decades. If supported by further, multivariate analyses, this finding suggests amendments to what has become standard strategic management thinking, perhaps in favor of earlier and more conventional microeconomic focus on profits
