Sentence examples for fields in the formation from inspiring English sources

The primary task of this investigation consisted in testing of the efficiency of small-scale IGWs and seismogenic electric fields in the formation of the ionospheric disturbances prior to an earthquake.

In the present work, we analyze the competition between tidal winds and electric fields in the formation of blanketing sporadic E layers (Esb) over São Luís, Brazil (2° 31′ S, 44° 16′ W), a quasi-equatorial station.

It is believed that the helical structure is one of the important pieces of evidence pointing to the major role played by magnetic fields in the formation of these jets.

Therefore, this allows us to investigate the role of the electric field in the formation or disruption of Esb.

Hedges perpendicular to the slope at the lower end of sloping fields result in the formation of soil terraces.

The main purpose of this work is to simulate the competition between winds and electric fields in the Esb formation over Brazilian quasi-equatorial region.

The production of most major oil fields in the Dainan Formation is now in decline; thus, a precise description of the sedimentary facies of these reservoir sandstones is greatly needed.

In the similar way as the interaction of solar wind with Earth's magnetic field results in the formation of magnetosphere which effectively shields the planet from the solar wind, the possibility that magnetic anomaly regions on Moon can form small-scale magnetospheres ("mini-magnetospheres") has been suggested from Lunar Prospector observations (Lin et al. 1998).

However, in our work the main purpose is to quantify the role of winds and electric fields in the Es layer formation over a peculiar equatorial region.

As the alternating current exists in the interior of the transmitter coil, a time-varying magnetic field must exist in the formation around the wellbore; thus, the induced magnetic field near the receiver coils should be a time-harmonic electromagnetic field.

Since then, the country's crude oil industry has seen many ups and downs, including the nationalization of oil fields in the 1950s and the formation of OPEC in the 1970s.
