The graphs of the ratio of the electric field inside the plasma and the incident electric field versus the incident angle, the geometrical dimension of the elliptical plasma column and cyclotron frequency are presented separately. Finally, scattering of the same waves from an elliptical cylindrical ...
where EF is the exposure factor, F is the exposure frequency (days/year) (365 days/year), ED is the duration of exposure (years) (70 years, EPA lifetime health risk), and AT is the average time (ED × 365 days/year). $${D}_{\text{inh}}=(\text{C}\times \text{IR}\ti...

In addition, enhanced UHI warming effect caused an increase in the frequency and intensity of warm temperature extremes in the region. A faster increase in night time temperatures than day time resulted in a decrease in diurnal temperature range of the region. Considering the high rate of warming...
in electrical contact therewith. The probe is adjustably movable into and out of the waveguide so that the probe together with the bushing thereabout forms a quarter wavelength stub extending into the waveguide and resonant at the frequency of the input signal. Electrical energization of this probe...
