Diffraction patterns were measured on a polycrystalline bcc Fe foil using a Mössbauer powder diffractometer with high sensitivity. Measurements with and without a magnetic field normal to the scattering plane showed large differences in the diffracted intensities of the different nuclear resonances. These magnetic effects on diffraction intensities were interpreted successfully with a single sc...

background and aim: tinnitus is a distressing symptom for which few treatments exist. low-frequency repetitive transcranial magnetic stimulation (rtms) of the temporal cortex has been proposed as a treatment for chronic tinnitus. this study determined relationship between psychoacoustic parameters such as loudness and frequency of tinnitus and outcome with rtms treatment. methods: twenty six pa...

This is the first study on the free vibrational behavior of sandwich panels with flexible core in the presence of smart sheets of oil which is capable of the excitation of magnetic field. In order to model the core, the improved high order theory of sandwich sheets was used by a polynomial with unknown coefficients first degree shear theory was used for the sheets. The derived equations based o...

Background and Purpose The purpose of this study is to demonstrate the magnetic resonance features of intracranial vertebrobasilar artery dissections and to determine the potential and limitations of magnetic resonance imaging in their diagnosis. Methods We studied five consecutive patients with angiographically verified intracranial vertebrobasilar artery dissection with magnetic resonance ima...

Oils containing both fluorescent semiconductor and magnetic oxide nanoparticles are used to produce oil in water emulsions. This technique produces oil droplets with homogeneous fluorescence and high magnetic nanoparticle concentrations. The optical properties of the oil droplets are studied as a function of the droplet sizes for various concentrations of fluorescent and magnetic nanoparticles....

OBJECTIVE It is important to have data about occupational magnetic field intensity to consider the contribution of occupational magnetic field exposure on the human body. We conducted research on exposure to occupational magnetic fields and tried to qualify data on the distribution of magnetic field' intensity in certain general working environments with individual measurements. SUBJECTS AND ...
