Using discriminant analysis to identify financially unstable banks of Russia and the world

In this article the financial reporting is considered and the mathematical model for identification of financially unstable banks of Russia and the world is under construction. Special attention is paid to data collection. They shall be written down correctly and in one dimension for the further analysis. Presently, even more often use mathematical modeling in the analysis of any processes. There is such threshold value or limits of data when which crossing the organization, in our case bank, begins to work at a loss. By means of models the forecast for a future period is done the same. In the bank sphere of Russia since 2013 there were changes and the Bank of Russia toughened control over credit institutions. It became the beginning to mass verification of the reporting of credit institutions and mass revocations of licenses

Adipositas im Kindes- und Jugendalter – eine retro­spektive Studie

The investigation was centered on the morphological features of the conjunctiva-cornea transition (limbus) of the rabbit eye and the proliferative behavior of its epithelium. The eyes were processed for examination with light and electron microscopy, as well as for autoradiography after intravitreal injection of [H-3]thymidine ([H-3]TdR). At the sites of extraocular muscle insertion, the vascularization of the stroma extended to the peripheral cornea, and the limbal epithelium was thin with its basal stratum made up by clear cuboidal cells. In between the muscle insertions, the cuboidal clear cells, as well as the stroma blood vessels; were scarce. At the light microscope level, the basement membrane was distinct in the cornea but not in the limbus or the conjunctiva. Autoradiographs demonstrated that, at the limbus, the basal cells migrated very quickly to the suprabasal region and remained there up to the 28-day interval. Labeled cells were identified in all epithelial layers of the cornea, including the basal one, at 21 and 28 days but not in the limbal basal clear cells. The rate of renewal of conjunctival epithelium was similar to that observed for the transition with scarce clear cells. The high-resolution autoradiographs demonstrated that the basal cuboidal clear limbal cells exhibit a quick renewal and that they are not label-retaining cells. These latter ones were detected all over the corneal epithelium and in the suprabasal layers of the limbus up to 28 days, in physiological conditions, without the need of stimulation by damage to the corneal epithelium

Влияние релаксационной прочности зерен и межзеренных границ в котельных сталях на работоспособность поверхностей нагрева

Представлены экспериментальные результаты исследований отечественной разработки аустенитной хромомарганцевой стали 10Х13Г12С2Н2Д2Б (Ди-59). На основе рентгенометрии показано, что осцилляции внутренних напряжений при циклическом изменении температуры, сопровождающиеся процессами релаксации при перемене знака, окажут существенное влияние на прочностные характеристики и послужат причиной термической усталости металла, а критерии релаксации напряжений и условия их протекания станут определяющими для работы металла при высоких температурах эксплуатации. Обоснованный выбор температуры эксплуатации, существенно повышающий релаксационную прочность зерен и межзеренных границ сплава, является основой продления ресурса работоспособности

Decolorization of synthetic dyes by laccase immobilized on epoxy-activated carriers

The Myceliophthora thermophila laccase was covalently immobilized on polymethacrylate-based polymers (Sepabeads EC-EP3 and Dilbeads NK) activated with epoxy groups. The enzyme immobilized on Sepabeads EC-EP3 exhibited notable activity (203 U/g) along with remarkably improved stability towards pH, temperature and storage time, but no increased resistance to organic solvents. In addition, the immobilized laccase also showed good operational stability, maintaining 84% of its initial activity after 17 cycles of oxidation of ABTS. The immobilized biocatalyst was applied to the decolorization of six synthetic dyes. Immobilized laccase retained 41% activity in the decolorization of Methyl Green in a fixed-bed reactor after five cycles. The features of these biocatalysts are very attractive for their application on the decolorization of dyes in the textile industry in batch and continuous fixed-bed bioreactors. To our knowledge, this is the first report on immobilization of laccase on Sepabeads carriers and its efficient dyes decolorization.We thank Drs. Moreno Daminati and Paolo Caimi (Resindion) and Vyasa Rajasekar (DilComplex) for providing us Sepabeads EC-EP3 and Dilbeads NK polymers, respectively.

Activity of metal powders based on aluminum, boron and magnesium

This study investigates the metal powders activity based on aluminum, boron and magnesium, used in composite solid propellant as fuel additives. The paper presents data of metal powders activity: the onset temperature of oxidation and the intense oxidation temperature, the weight gain in the temperature range of 400 - 1200° C and the maximum oxidation rate of the metal powders
