The European Commission (EC) mandates that from July 1, 2014, Mobile network operators (MNO) shall offer the possibility to other parties, referred to as Alternative roaming provider (ARP), to offer ‘roaming services’. When a subscriber of a national MNO, referred to as Domestic service provider (DSP) in this context, travels abroad, that person should be entitled to receive voice, data, SMS an...

The title compound, Mn(4)(H(2)O)(4)[Ge(OH)(2)(HPO(4))(2)(PO(4))(2)], was synthesized by the solvothermal method. Its crystal structure is isotypic with the iron and cobalt analogues [Huang et al. (2012 ▶). Inorg. Chem.51, 3316-3323]. In the crystal structure, the framework is built from undulating manganese phosphate sheets parallel to (010) inter-connected by GeO(6) octa-hedra (at the inversio...

Electron beam irradiation is well known to induce damage in materials. The structural transformation involved in the damage is usually believed to be an irreversible solid state chemical reaction. Here we use in situ transmission electron microscopy (TEM) combined electron-energy loss spectroscopy (EELS) technique in an aberration-corrected TEM to track the structural transformation in spinel M...

This study explores the effect of introducing additional alloy elements not only in a different order but also at different stages of the Ruhrstahl-Heraeus (RH) process of low-carbon silicon steel production. A more economical method, described as "pre-alloying", has been introduced. The evolution of MnO-FeO inclusions produced by pre-alloying was investigated. Results show that spherical 3FeO·...

Chemical analytical data have been obtained for kraisslite and mcgoverdite. Kraisslite contains both trivalent and pentavalent arsenic in the weight ratio of 3 :4. Specimens from different parageneses have relatively invariant chemical compositions, which suggests some degree of ordering of Mg, Mn, andZn. The average of five analyses yields MgO 2.6, MnO 52.0, ZnO 8.6, FerO, 2.0, AsrO, 6.69, Alr...

Gliomas are notoriously aggressive, malignant brain tumors that have variable response to treatment. These patients often have poor prognosis, informed primarily by histopathology. Mathematical neuro-oncology (MNO) is a young and burgeoning field that leverages mathematical models to predict and quantify response to therapies. These mathematical models can form the basis of modern "precision me...

The charge ordering in the bilayer manganite system La 2−2x Sr 1+2x Mn 2 O 7 with 0.30 ≤ x ≤ 0.50 has been studied by neutron diffraction. The charge order is characterized by the propagation vector parallel to the [1 0 0] direction (MnO 2 direction), but the correlation length is short-ranged and extremely anisotropic, being ∼ 0.02a * and ∼ 0.2a * parallel and perpendicular to the modulation d...

Inelastic neutron scattering measurements of "/-MnO 2 at 30, 100 and 200 K give S(Q, to) maps of intensity over large o 1 energy and momentum transfer ranges (from 0 to 1 eV and from 0 to 40 A , respectively). They reveal a ridge of intensity due to recoil of free particles with effective mass of -1 amu. The width of the recoil line is one order of magnitude greater than that anticipated from t...

usd7 is one of the steel products of isfahan steel company. it is cast in continuous casting moulds and rolled up to a rod of 5 mm diameter. finally, it is wire drawn up to 3 mm and used as welding electrodes. this steel contains 0.05 to 0.09 wt. % carbon. the acceptable limit of the aluminium in this class of steel is less than 0.003 wt%. therefore, it is categorized as rimmed steel. during fo...
