Magnetic field  improved germination parameters. The germination of Catharanthus roseus seeds is lost under salinity conditions. The effect of different strengths of magnetic field and exposure durations on the germination of C. roseus seeds under salinity conditions (19 mS cm-1) were investigated. The experiment was conducted  with factorial arrangement based on a completely randomized design ...

Agar/Fe3O4 nanocomposites were synthesized in the presence of an external magnetic field (~ 0.4 Tesla) and their characteristics were compared with the samples synthesized without considering the external magnetic field. In this study we used Fe2+ and Fe3+ for synthesizing Fe3O4 magnetic nanoparticles in the presence of agar as polymeric additive, by co-precipitation technique. Vibrating sample...

in this article, the second quantization method has been used to investigate some thermodynamic properties of spin-polarized metallic nanowire in the presence of magnetic field at zero temperature. we have been observed that in different magnetic field, the equilibrium energy of system increases as the density increases. the spin-polarization parameter corresponding to the equilibrium state of ...

We report on the design and performance of a highly sensitive combined He/Cs magnetometer for the absolute measurement of magnetic fields. The magnetometer relies on the magnetometric detection of the free spin precession of nuclear spin polarized He gas by optically pumped cesium magnetometers. We plan to deploy this type of combined magnetometer in an experiment searching for a permanent elec...

20 Optically pumped atomic magnetometers measure the Larmor frequency νL at which the bulk magnetization of a spin-polarized alkali metal vapour in a glass cell precesses around the field of interest B0. !e precession frequency is related to the modulus of the magnetic field by νL=(γ/2π)|B0|, where γ/2π≈3.5Hz/nT for 133Cs, so that the magnetic field measurement consists in a frequency measureme...

Recently atomic magnetometers are one of the best tools in biomagnetic measurement such as magnetic field of brain and heart. In this paper, the technology of optically pumped atomic magnetometer based on circularly polarized light absorption pumping is described. We have been investigated a new method for measuring polarization effect in an alkali vapor based on polarized light transmission. I...

In this paper, an efficient neural network based estimation technique has been studied to estimate the magnetic field strength near any power substation, and to assess the possible exposure to electromagnetic radiation received by the residents living near that substation. The measurement and the estimation were carried out in close proximity to different high powered equipment at four differen...

The measurement of the impedance of biological tissue can be a non-invasive method to find new data of diagnostic relevance. A system for a noncontact measurement of the electrical impedance of biological tissue is presented. The system consists of an excitation coil and two sensing coils coupled together as a gradiometer. The excitation coil is driven by an alternating current. Due to this alt...
