O1 Propagator-Resolved 2D Exchange in Porous Media in the Inhomogeneous Magnetic Field Lauren Burcaw 1, Mark Hunter 2, Paul Callaghan 2 1 Victoria University of Wellington, 2 SCPS, Victoria University of Wellington We present a propagator-resolved 2D exchange spectroscopy technique for observing fluid motion in a porous medium. The susceptibility difference between the matrix and the fluid is e...

A device for precise magnetic measurements of superconductive coils was designed, built and installed at the synchrotron radiation source ANKA, Forschungszentrum Karlsruhe. Accurate magnetic field measurements are a prerequisite for the characterization and optimization of insertion devices. The new device allows measuring the magnetic field magnitude of test coils with a longitudinal precision...

We study the bottom of the spectrum of a magnetic hamiltonian with axisymmetric potential in R. The associated magnetic field is planar, unitary and non-constant. The problem reduces to a 1D family of singular Sturm-Liouville operators on the half-line. We study the associated band functions and we compare it to the “de Gennes” operators arising in the study of a 2D hamiltonian with monodimensi...

We consider a thought experiment where two distinct species of 2D particles in a perpendicular magnetic field interact via repulsive potentials. If the magnetic field and the interactions are strong enough, one type of particles forms a Laughlin state and the other type couples to Laughlin quasiholes. We show that, in this situation, the motion of the second type of particles is described by an...

in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertil...

Magnetic field mapping with micrometric spatial resolution and high sensitivity is a challenging application, and the technological solutions are usually based on large area devices integrating discrete magnetic flux guide elements. In this work we demonstrate a high performance hybrid device with improved field sensitivity levels and small footprint, consisting of a ultra-compact 2D design whe...

introduction increase in alpha band is observed when blood perfusion in frontal area of head decreases. the present study evaluated some changes in the alpha band particularly, alpha-1 of frontal and central areas of the head, when several areas were exposed simultaneously to magnetic field. materials and methods five points of head (f3, f4, cz, t3, and t4) of twenty healthy male participants w...

this study is considering a micropolar fluid flow over a porous stretching sheet in the presence of thermal radiation and uniform magnetic field. the effects of local variation in thermal conductivity of micropolar fluid on heat transfer rate from the sheet are investigated; besides, the impacts of radiation, magnetic field and porous sheet on variations of thermal boundary layer thickness are ...

background : electromagnetic fields are associated with production, transmission and use of electricity. in this  tudy we have investigated the effects of short and long time alternative magnetic fields' (amf, 50 hz) exposure on the secretion of hypothalamic-pituitary-gonadal axis in the male rats. methods : forty eight wistar male rats, same range of age and weight were divided into four group...
