the changes in time and location of surface temperature from a water body has an important effect on climate activities, marine biology, sea currents, salinity and other characteristics of the seas and lakes water. traditional measurement of temperature is costly and time consumer due to its dispersion and instability. in recent years the use of satellite technology and remote sensing sciences ...

 Background and aim:  Magnetic resonance imaging as one of the best medical scanning technique is considered to be the most important sources of static magnetic fields. The staffs of MRI ´s units frequently exposed to these static magnetic fields. This study aims to determine the occupational exposure level to mentioned field and its related health effects in MRI´s units.    Methods:  The occup...

The transport of ionospheric ons from a source in the polar cleft ionosphere through the polax magnetosphere is investigated using a two-dimensional, kinetic, trajectory-based code. The transport model includes the effects of gravitation, longitudinal magnetic gradient force, convection electric fields, and parallel electric fields. Individual ion trajectories a well as distribution functions a...

introduction: neural stimulation is a promising new technology for the treatment of medically-intractable seizures.  transcranial magnetic stimulation (tms) is a simple, non-invasive, low cost technique which is widely used in neurophysiology. in a few studies that have been performed at different frequencies the therapeutic effects of this technique were not obvious. repetition of low frequenc...

We analyse spectropolarimetric observations of the penumbra of the NOAA AR 10953 at high spatial resolution (0.3). The full Stokes profiles of the Fe I lines at 630.1 nm and 630.2 nm have been obtained with the Solar Optical Telescope (SOT) on board the Hinode satellite. The data have been inverted by means of the SIR code, deriving the stratifications of temperature, line of sight velocity, an...
