Therefore, only the effects of atmospheric variations, F10.7 variations, seasonal variations, and atmospheric waves propagating from the lower atmosphere are included.
When the signal encounters turbulence in the atmosphere, rapid variations in the refractive index along the path will lead to fluctuations in the signal level received (Mandeep and Hassan 2004; Mandeep et al. 2006; Karasawa et al. 1988a).
Among the explanations are fluctuations in the amount of energy received from the sun, changes in the amount of volcanic dust in the atmosphere and variations in the average elevation of the continents.
For example, volcanoes that spew tons of small particles into the upper atmosphere and variations in sunspots provide unique experiments to test the accuracy of climate models built on the basis of our understanding of climate.
1H stray-field (STRAFI -MRI one-dimenSTRAFI -MRIes (1D profiles) of visible-light cured resins were obtained in the presence of oxygen from the atmosphere, and the varimages of magnetization with irradiation time was recorded for each resin slice.
The differences in learning atmosphere bring about variations in social presence and enjoyment of learning.
It is well known that the ionosphere, a conductive, ionized region of the Earth's atmosphere, exhibits significant variations in the peak plasma density residing typically in a relatively thin layer (200 400 km) in the F-region.
The atmosphere has significant variations in density and temperature with time of day, latitude, volcanic activity, and surface frost abundance.
But going through the show, you see that Morandi's graphic gifts are so subtle he is able to get over the finest variations of atmosphere, tone and light just through infinitely small variations in the direction of the crosshatchings.
The postpolymerization was clearly shown in the isothermal mode and under N2 atmosphere by following the variation of the glass transition temperature of the samples.
