    A good article (GA) is an article that meets a core set of editorial standards but is not featured article quality. Good articles meet the good article criteria, passing through the good article nomination process successfully. They are well written, contain factually accurate and verifiable information, are broad in coverage, neutral in point of view, stable, and illustrated, where possible. Azinphos-methyl is a member of the class of benzotriazines that is 1,2,3-benzotriazine substituted by an oxo group at position 4 and a [(dimethoxyphosphorothioyl)sulfanyl]methyl group at position 3. It has a role as an EC (acetylcholinesterase) inhibitor, an EC . 2 N2 - O-model. Relative amplitudes and phases for the O and N2 concentrations and the gas temperature Tg. Dashed lines: diffusive equilibrium; solid lines: diffusion of O through atomic oxygen these processes are of no significance for the diurnal variations.

[11] In this work, we extend this simple formalism to describe the dynamics of all major sources of the magne-tospheric field, including the partial ring current, cross-tail current, and Birkeland.

The relationship of auroral zone geomagnetic activity to solar wind power input functions are examined, and a least squares prediction filter, or impulse response function is designed from the data. The magnetosphere and ionosphere are coupled into a power circuit by field-aligned currents. If there were only Hall current in the ionosphere, the problem of magnetosphere-ionosphere interaction would not have arisen.

Field-aligned currents could be seen as emerging as a result of the break in the magnetospheric current across the tail, since the Hall current is divergence-free and does Author: P. Sedykh. For the two models, particles are accelerated and turned toward the earth within the neutral sheet and are ejected from the neutral sheet with small pitch angles to a magnetic line of force, with energies of tens of kilovolts.

The future availability of rare earth elements (REEs) is of concern due to monopolistic supply conditions, environmentally unsustainable mining practices, and rapid demand growth.

We present an evaluation of potential future demand scenarios for REEs with a focus on the issue of comining.

Quantifying the timescales of current geological processes is critical for constraining the physical mechanisms operating on the Earth today.
