The isobaric heat capacity of LaSrMnFeO5.5 ferrite is investigated within the temperature range of 298.15-673 K by a calorimetric method. On the curve of the dependence of the heat capacity on temperature, the λ-type effect is revealed relating to a phase transition of the second kind. Temperature dependencies of the thermodynamic functions S 0(T), H 0(T) -H 0(298.15), and Φ xx (T) are calculated. The temperature dependencies of permittivity and electrical resistance are studied within the temperature range of 303-493 K, and the results show that the composition under study has semiconductor properties. © 2012 Pleiades Publishing, Ltd.

The developed Health Insurance Billing Information System relates to computer-assisted posting and processing of insurance claims. Medical providers prepare, post and receive health insurance claims. This process is important for running a medical practice. The developed information system performs data receipt, formatting, editing and processing; enables modern technologies and improves functionality of the former legacy information system that has provided substantial value over its years in existence. This article describes some of the components and design of the developed information system. © 2010 IEEE. Source

Manganite ferrites NdM1.5 II MnFeO6 (M II = Mg, Ca, Sr, Ba) were synthesized from neodymium(III), manganese(III), and iron(III) oxides and alkaline-earth metal carbonates by a ceramic technology. By grinding the obtained compounds in a ball mill, their nanostructured particles were produced, the sizes of which were determined with an electron microscope. X-ray diffraction study established that the nanostructured compounds crystallize in the cubic and tetragonal systems with the following lattice parameters: NdMg1.5MnFeO6 (tetragonal): a = 10.955 Å, c = 17.848 Å, V0 = 2141.975 Å3, Z = 16, Ve1.cel1 0 = 133.873 Å3, ρX-ray = 4.80 g/cm3, and ρpycn = 4.76 ± 0.05 g/cm3; NdCa 1.5MnFeO6 (cubic): a= 10.809 Å, V0 = 1262.864 Å3, Z = 8, Ve1.cel1 0 = 157.858 Å3, ρX-ray = 4.32 g/cm3, and ρpycn = 4.27 ± 0.03 g/cm3; NdSr 1.5MnFeO6 (cubic): a = 10.911 Å, V0 = 1298.953 Å3, Z = 8, Ve1.cel1 0 = 162.369 Å3, ρX-ray = 4.93 g/cm3, and ρpycn= 4.88 ± 0.05 g/cm3; and NdBa 1.5MnFeO6 (tetragonal): a = 11.011 Å, c = 18.001 Å, V0 = 2182.479 Å3, Z = 16, V e1.cel1 0 = 136.405 Å3, ρX-ray = 6.78 g/cm3, and ρpycn= 6.75 ± 0.07 g/cm3. © 2013 Pleiades Publishing, Ltd.
