conclusions comprehensive protection programs with on-the-job training courses for staff members are strongly recommended, as well as, the provision of radiological shields and gonad shielding protocols in radiology departments to reduce the patient’s radiation dose during radiological examinations. materials and methods a retrospective, observational cross-sectional study on the application of...

[1] We seek to determine whether the adiabatic plasma transport and energization resulting from electric and magnetic drift can quantitatively account for the plasma sheet under weak and enhanced convection observed by Geotail presented in the companion paper [Wang et al., 2004]. We use a modified Magnetospheric Specification Model to simulate the dynamics and distributions of protons originati...

Magnetic manipulation is a promising technique for lab-on-a-chip platforms. The magnetic approach can avoid problems associated with heat, surface charge, ionic concentration and pH level. The present paper investigates the migration of diamagnetic particles in a ferrofluid core stream that is sandwiched between two diamagnetic streams in a uniform magnetic field. The three-layer flow is expand...

Local diamagnetic passive shims can substantially reduce brain BO inhomogeneity, resulting in greatly improved signal loss and image distortion artifacts in BOLD fMRI data. For a standard fMRI-type EPI sequence, placement of 5.5 cm3 of diamagnetic material in the mouth reduced by 74% the number of voxels in the inferior frontal cortex experiencing >75% signal loss. A diamagnetic earplug reduced...

 is negative in diamagnetic materials and positive in paramagnetic materials. This means that the field and NMR frequency are both typically reduced in diamagnetic materials and enhanced in paramagnetic materials (though in calculating it is important to take account of the effect of the sample shape and the sphere of Lorentz). Paramagnetic/diamagnetic materials are attracted/repelled by a m...

BACKGROUND Diamagnetic levitation is a technique that uses a strong, spatially varying magnetic field to simulate an altered gravity environment, as in space. In this study, using Streptomyces avermitilis as the test organism, we investigate whether changes in magnetic field and altered gravity induce changes in morphology and secondary metabolism. We find that a strong magnetic field (12T) inh...
