the ever increasing rate of power consumption has led to an increase in public exposure to extremely low frequency magnetic fields (elf-mfs) and brought severe concerns about their health effects. considering previous studies and the facts about potential health effects of these fields, the present study aimed to evaluate the elf-mf flux densities from power distribution lines near hospitals i...

A scheme is presented for mapping the connectivity of a potential magnetic field arising from an arbitrary distribution of discrete sources. The field lines interconnecting the sources are classified into Nd domains, defining the field’s connectivity. The number of domains is shown to depend on the number of sources and on the numbers of nulls and separators according to a simple relation. A cl...

this contribution determines suitable fingerprinting properties for sediment source discrimination within theamrovan and atary catchments in semnan province, iran. these catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...

in this paper, it has been shown that there is a special relation between horizontal and vertical gradients of gravity data and the vertical and horizontal components of magnetic data for some of 2-d sources. it has been shown that the hilbert transform is useful in calculating the vertical gradient of gravity and magnetic anomalies from the horizontal gradient for transformation of gravity and...

This is a very interesting paper looking at combining HNMR and AMS data to deliver a more complete picture of organic particulates in a polluted European environment. The real novelty of this work is in the combination of the independent factorisation of both datasets to deliver insights into the processes that might not be possible with only one of the datasets. The two data sources do not agr...

diffusion weighted imaging uses the signal loss associated with the random thermal motion of water molecules in the presence of magnetic field gradients to derive a number of parameters that reflect the translational mobility of the water molecules in tissues. with a suitable experimental set-up, it is possible to calculate all the elements of the local diffusion tensor (dt) and derived paramet...

It is important to determine the location of electromagnetic noise sources within the electrical and electronic equipment under real operating conditions, to reduce the undesired noise emissions from the equipment. In this work we develop a system to locate electromagnetic sources, especially low-frequency (< MHz) magnetic dipoles (current loops), by measuring the magnetic field distributions a...

iron oxide minerals in soils provide valuable insights into pedogenic processes. a wealth of such information has been obtained by rock magnetic investigations on temperate soils but similar studies on tropical soils are rare. here, we report rock magnetic data on pristine soil profiles and surficial soils from five catchments in the tropical southern india and throw light on the pedogenic proc...
