The Combined EIS-NVSS Survey Of Radio Sources (CENSORS) is a 1.4 GHz radio survey selected from the NRAO VLA Sky Survey (NVSS) and complete to a flux-density of 7.2 mJy. It targets the ESO Imaging Survey (EIS) Patch D, which is a 3 by 2 square degree field centred on 09 51 36.0 −21 00 00 (J2000). This paper presents the results of spectroscopic observations of 143 of the 150 CENSORS sources. Th...
various geological units in an area often exhibit different magnetic properties. due to this distinction in magnetic properties of the geological units, a correlation between the type of a geological unit and its magnetic response can be established. to determine the lateral and vertical extents of geological units from the magnetic data in a survey area, a number of filters for processing magn...
In the extremely low frequency range (3 to 300 Hz), the intensities of electric and magnetic fields increase with increasing voltage and current. If the intensities of electric and magnetic fields are high compared with standard exposure limits, they can have harmful effects on human health. In the vicinity of power lines and high voltage power stations, the intensities of these fields are usua...
