We show that a real bounded sequence (xn) is Cesaro convergent to l if and only the of averages with indices in [αk,αk+1) converges for all α>1 . If, addition, (xn)...

The title compound, strontium trimanganese tris-(ortho-phosphate), was synthesized under hydro-thermal conditions. Its structure is isotypic to that of the lead analogue PbMn(II) 2Mn(III)(PO4)3. Two O atoms are in general positions, whereas all others atoms are in special positions. The Sr and one P atom exhibit mm2 symmetry, the Mn(II) atom 2/m symmetry, the Mn(III) atom and the other P atom ....

Sodium-ion batteries are considered as prime alternatives to lithium-ion batteries for large-scale renewable energy storage units due to their low cost and the abundance of sodium bearing precursors in the earth's mineral deposits. In the current work, a 3D NASICON framework Na3V2(PO4)3/carbon cathode electrode with 20-30 nm Na3V2(PO4)3 nanoparticles uniformly encapsulated interconnecting one-d...

The title compound, SrNi2Fe(PO4)3, synthesized by solid-state reaction, crystallizes in an ordered variant of the α-CrPO4 structure. In the asymmetric unit, two O atoms are in general positions, whereas all others atoms are in special positions of the space group Imma: the Sr cation and one P atom occupy the Wyckoff position 4e (mm2), Fe is on 4b (2/m), Ni and the other P atom are on 8g (2), on...

The title compound, Mn2Zn(PO4)2·H2O, was obtained under hydro-thermal conditions. The structure is isotypic with other transition metal phosphates of the type M 3- xM' x (PO4)2·H2O, but shows no statistical disorder of the three metallic sites. The principal building units are distorted [MnO6] and [MnO5(H2O)] octa-hedra, a distorted [ZnO5] square pyramid and two regular PO4 tetra-hedra. The con...

We have undertaken a vibrational spectroscopic study of paravauxite the Siglo XX mine, Bustillo Province, northern of Potosí department, Bolivia. This mine is important source for rare and unusual secondary phosphate minerals and is the type locality for a number of rare phosphates such as vauxite, sigloite, metavauxite and for jeanbandyite. The chemical formula of the studied sample was determ...

BACKGROUND The Electrophysiologic Study Versus Electrocardiographic Monitoring (ESVEM) study was designed to compare the accuracy of predictions of antiarrhythmic drug efficacy made by electrophysiological study (EPS) with those made by Holter monitoring (HM) combined with exercise testing. The present study describes the baseline characteristics and the response to drug efficacy tests of 486 r...

Premature and high-risk infants require accurate delivery of nutrients to promote appropriate growth. Continuous enteral feeding methods may result in significant fat and micronutrient loss. This study evaluated fat loss in enteral nutrition using current strategies for providing high-risk infants fortified human milk (HM). The fat content of HM was measured by IR analyzer in a simulated feedin...
