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 …

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 …

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 …

Autoradiographische Modelluntersuchungen an der Maus zum Einfluss einer achtwöchigen 50-Hz-Magnetfeld-Exposition auf DNA-Reparatur und Zellproliferation in der Milz
… of ³H-thymidine (TdR) the influence of an 8-week magnetic field (MF) exposure of 50 Hz with 0.1 mT or 1 mT flux density on cell proliferation in the spleen germinal center and nuclear (n) DNA-repair capacity in the mantle zone of follicular spleen cells of adult mice. Altogether 72 male mice were …

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 …
