In order to study on effect of magnetic field on germination characteristics and early growth of marigold (Calendula officinalis L.) seeds an experiment was carried out in laboratory conditions in Arak University of Iran. Seeds were magnetically exposed to magnetic field strengths, 100 or 200 mT for different periods of time; D1 (control), D2 (1 h), D3 (6 h), D4 (12h), D5 (24 h) and D6 (contin...

We have obtained the spectral and spatial field correlation functions, C(E)(Deltaomega) and C(E)(Deltax), respectively, from measurement of the microwave field spectrum at a series of points along a line on the output of a random dielectric medium. C(E)(Deltaomega) and C(E)(Deltax) are shown to be the Fourier transforms, respectively, of the time of flight distribution, obtained from pulsed mea...

Pulsar dynamic spectra exhibit high visibility fringes arising from interference between scattered radio waves. These fringes may be random or highly ordered patterns, depending on the nature of the scattering or refraction. Here we consider the possibility of decomposing pulsar dynamic spectra – which are intensity measurements – into their constituent scattered waves, i.e. electric field comp...
