This article investigates to what extent Trump's protectionism influences the American steel industry and trade relationship with China. The investigation first looks at historical events, insight into one of most controversial laws in United States foreign policy - Smoot–Hawley Tariff Act which exacerbated Great Depression on global scale. Further analysed are current actions a relationship, p...

MHD in protostellar discs is modified by the Hall current when the ambipolar diffusion approximation breaks down. Here I examine the Balbus-Hawley (magnetorotational) instability of a weak, vertical magnetic field within a weakly-ionised disc. Vertical stratification is neglected, and a linear analysis is undertaken for the case that the wave vector of the perturbation is parallel to the magnet...

Local hydromagnetic simulations of accretion disc turbulence provide now the most convincing evidence that the origin of turbulence in discs could be the Balbus{Hawley magneto-rotational instability. The main results of such calculations are highlighted with particular emphasis on the generation of large scale magnetic elds. Comparison with mean-eld dynamo theory is made. This theory is then us...
