BACKGROUND: Dehydroepiandrosterone (DHEA) has been suggested as an immunostimulating steroid hormone, of which the effects on the development of dendritic cells (DC) are unknown. The effects of DHEA often oppose those of the other adrenal glucocortic

The performance of sandwich heads for high-density video recording can be improved if the soft magnetic layer is given a special profile. This is achieved by sputter deposition of amorphous Co films on substrate tiles that have a grooved surface prof

The shape of an internal magnetic shield in a TV tube determines in a complex way to what extent the influence of the earth's magnetic field on the TV image is reduced. Conformal mapping and finite element calculations of the field distribution in mo

A study of the microstructural influence on the coercive field of polycrystalline MnZn-ferrites is presented. The coercive field, HC, is found to depend on the grain size D as HC α D-1. This dependence can be accounted for by assuming a grain bounda

Fe/FeN multilayer films with Fe and FeN layer thicknesses in the range of respectively 80–110 and 30–80 A have been prepared using a reactive diode rf sputtering system. Their crystallographic characteristics and magnetic properties have been inv

OBJECTIVE: To study the effects of the active metabolite of vitamin D(3), 1,25(OH)(2)D(3), an immunomodulatory hormone, on the generation of so-called immature dendritic cells (iDCs) generated from monocytes (Mo-iDCs). DESIGN AND METHODS: Human perip

The effect of inducing a uniaxial anisotropy in microcrystalline Fe/FeCrB multilayers by applying a magnetic field during deposition was studied. Not only a reduction of remanent magnetization, but also an increase of permeability (at 10 MHz) are the

The magnetic properties of Fe/CoZrNb multilayers were studied by ferromagnetic resonance as a function of CoZrNb interlayer thickness t c . For t c ⩾40 A the CoZrNb remains amorphous, a fairly good agreement exists between the as computed and exper

Interface mixing in ion beam sputtered Fe/CoNbZr and Fe/Co multilayers was studied by means of magnetostriction measurements. With decreasing period of modulation the magnetostriction of the multilayer increases. This effect is attributed to the pres
