introduction low dose rate brachytherapy sources have been widely used for interstitial implants in tumor sites, particularly in prostate. dosimetric characteristics of a new irseed 125i brachytherapy source have been determined using the lif thermoluminescent dosimeter (tld) chips. materials and methods dose rate constant, radial dose function, and anisotropy function around the irseed 125i so...

in this research formability behavior and texture of st14 low carbon steels produced by foolad mobarakeh plant for deep drawing application had been studied. plate textures were characterized by x-ray diffraction technique. to evaluate formability behavior one dimensional tensile test was carried out and related parameters were recognized. moreover eriksson experiment and spherical pattern prin...

Rock anisotropy plays an important role in engineering behavior of rocks. Slates are anisotropic rocks which have long been used for gable roof, floor tiles, borrow materials, and other purposes. The slates studied in this research are calcareous and have a porphyro-lepidoblastic texture. To determine the role of the anisotropy on the tensile strength and fracture pattern, two variables includi...

A method is suggested to deduce the anisotropy in neutral pions by measuring the azimuthal anisotropy of photons in ultra-relativistic nuclear collisions. The ratio of the estimated anisotropy in photons to the anisotropy in neutral pions is seen to scale with a parameter which depends on photon multiplicity and anisotropy. This parameter can be determined from experimental data.

UNLABELLED Graded anisotropy magnetic materials possess a coercive field changing laterally with position. A simple fabrication procedure to produce such an anisotropy gradient in a polycrystalline Au/Co layer system without lateral thickness variation and with perpendicular magnetic anisotropy, prototypical for a large variety of thin film systems, is shown. The procedure uses light-ion bombar...

Despite strong anisotropy seen in analysis of seismic data from the NoMelt experiment in 70 Ma Pacific seafloor, a previous analysis of coincident magnetotelluric (MT) data showed no evidence for anisotropy in the electrical conductivity structure of either lithosphere or asthenosphere. We revisit the MT data and use 1D anisotropic models of the lithosphere to demonstrate the limits of acceptab...

A granular material is most likely to possess an initial anisotropic structure due to the depositional process or the previous stress history. There is also induced fabric anisotropy during shearing. Concerning the significant influence of fabric anisotropy on the stress-strain behaviour of a granular material, in-depth investigation on the two kinds of fabric anisotropy is essential. Initial f...
