  1. Elf magnetic field influence on ION Channels studied by Patch Clamp Technique: exposure set up and "Whole Cell" measurements on Potassium currents

    … effects of extremely low frequency (ELF) electromagnetic magnetic fields on potassium currents in neural cell lines ( Neuroblastoma SK-N-BE ), using the whole-cell Patch Clamp technique. Such technique is a sophisticated tool capable to investigate the electrophysiological activity at a single …

  2. The effects of pulsed static and oscillating magnetic fields on rat pineal serotonin N-acetyltransferase activity

    … about the possible hazardous effects of electromagnetic fields (EMF ' s) has resulted in attempts to address this issue. Several authors have shown that EMF exposure affects biological systems and more specifically the pineal enzyme, serotonin N-acetyltransferase (SNAT), inhibiting the enzyme …

  3. Recent lunar magnetism

    … (<1.5 Ga) is a mystery because common sources of magnetic fields (e.g. core dynamo and long-lived impact plasma fields) have not been present within the last 1.5 Ga. To better characterize the source of magnetization in young lunar samples, we conducted paleomagnetic measurements on several …

  6. Improving the settleability of a metal sulphide suspension by the application of a magnetic field

    … ions close to the particle surface by applying a magnetic field. This results in the reduction of inter-particle electrostatic repulsive forces and subsequent increase in the zeta potential of a suspension. For the purposes of this study, a copper sulphide suspension was used. A T-mixer was used …
