Dynamic Analysis of the Behavioural Patterns of the Largest Commercial Banks in the Russian Federation

This paper presents a pattern behavio ral analysis of 100 largest Russian commercial banks by total assets during an eight- year period: from the first quarter of 1999 to the second quarter of 2007. Bank performance indicators are analyzed. Structural similarities in the development of the banks are examined. A cluster analysis is applied to determine banks with a similar structure of operations. This analysis allows to estimate how the structure of the Russian banking system has been changing over time. In particular, it allows to identify prevailing patterns in the behavior of Russian commercial banks and to analyze the stability of their position in a particular pattern.Bank, dynamic pattern analysis, cluster analysis

Comparison of early reactions of the blood system in rats to immobilization, the action of hypoxia and the administration of erythopoietin

Three series of experiments were simultaneously carried on rats with the purpose of studying the action of different stimulants on the blood system; rats were subjected to immobilization, hypoxic hypoxia and erythropoietin administration. Changes in various cellular forms in the bone marrow, the thymus and the spleen were studied. A unitypical reaction, as in stress, was noted during the first hours; a reduction of the cell count in the lymphoid organs, a reduction of granulocytes and an increase of lymphoid cells in the bone marrow. The differences were chiefly quantitative. This was followed by stimulation of myelo and erythropoiesis determined by the specific features of the action applied. Nonspecific blood reaction was apparently due to activation of the adaptation mechanisms

Justification of binder material selection for carbon particles incorporation into fibrous electromagnetic radiation absorber

The paper presents justification of a binder material for incorporating carbon particles into the interfiber space of electromagnetic radiation absorber. A method for carbon particles incorporation into a fibrous material has been developed. It is based on applying a carbon-containing nanocomposite to the fibrous material’s surface. Previously, the research of carbon particles incorporation into a synthetic material by using an aqueous solution were carried out, which ensured a uniform distribution of carbon particles in the material structure. However, the properties of the material have changed significantly upon mechanical deformation. Therefore, the carbon particles incorporation process was investigated using various nanocomposites obtained on the basis of mixtures of vinyl acetate polymer, or epoxy polymer, or surface-active substance with carbon black. Based on the results of electron microscopic analysis and the reflection and transmission coefficients frequency dependences in the frequency range 0.7–17 GHz, the efficiency of using a nanocomposite based on a mixture of surface-active substance and carbon black to create electromagnetic radiation absorbers was justified. Such electromagnetic radiation absorbers have the transmission coefficient value about –18 dB and reflection coefficient value about –12 dB in the frequency range 7–13 GHz. Carbon-containing electromagnetic radiation absorbers based on fibrous material have thickness less than 3 mm, properties of flexibility and resistance to mechanical deformation. It can be used in various fields, in particular for hiding objects from radio frequency reconnaissance or protecting equipment from external interference.The paper presents justification of a binder material for incorporating carbon particles into the interfiber space of electromagnetic radiation absorber.

Opportunities and barriers for innovation and entrepreneurship in orphan drug development

Orphan diseases pose both a challenge to the global medical community and an opportunity for it to focus on global peace engineering and innovation. Where, any single orphan disease is rare, when taken as a whole they affect more than 250 million people throughout the world. This number by comparison is larger than the global number of cancer and AIDS patients. We add to the literature by mapping the available knowledge in the orphan drug development field and exploring the tensions at play for innovation and entrepreneurship in this field. We further add to the literature by providing a framework to review this field based on social systems theory. Our review highlights the gaps in research and proposes a path forward in understanding of and learning from the orphan drug development field

Improvement of information support for formation of management reporting on the example of the activities of an energy company

The purpose of the study is to develop a system for generating management reporting on the production activities of an energy company on the SAP Business Objects Platform. To build a reporting system, the following tasks has been set and solved: the conceptual and datalogical models of the data warehouse were created, data areas have been selected from the general data model, the data warehouse has been designed and developed, universes for report groups have been created, a mechanism for integrating data with the data warehouse has been implemented.The paper analyses the information and technological infrastructure of an energy company as well as formulates the basic requirements for the system being created for generating reporting. Two main subsystems have been designed: data storage and integration. The process of implementing the designed subsystems in physical form has been described using the appropriate software products: SAP Hana, SAP Universe Designer, SAP Data Services, SAP Business Intelligence.Thanks to the configured system through the corporate data bus, a relatively simple data integration mechanism became possible. In its information and technological architecture, the company managed to simulate an acceptable data warehouse model and set up the appropriate data flows. A complex data warehouse model has been implemented, and a convenient platform for further data processing has been provided. A clear data integration scheme is configured using SAP Data Services, with the ability to scale and configure the data loading schedule. The developed system has been put into operation and is used by employees to make management decisions within the framework of their professional activities

The geochronological framework of the Irumide Belt: A prolonged crustal history along the margin of the Bangweulu Craton.

Ion microprobe U-Th-Pb analyses of zircon from 40 granitoid rocks collected from the late Mesoproterozoic Irumide Belt in Central Southern Africa, along the southern margin of the Archean to Paleoproterozoic Bangweulu Block, provide a comprehensive set of age data for this complex orogen. The data indicate that the Irumide Belt is constructed on a basement of principally Paleoproterozoic (ca. 2.05–1.93 Ga) age with a subordinate Neoarchean (ca. 2.73 Ga) component, which is overlain by a platformal quartzite-pelite succession known as the Muva Supergroup. Previously published U-Pb detrital zircon data for the Paleoproterozoic Muva Supergroup, which show age populations that match all of the pre-1.9 Ga basement components identified within the Irumide Belt, suggest that the pre-Muva basement was assembled as a coherent block by ~1.8 Ga, which we refer to as the Bangweulu Craton. The southern margin of the Bangweulu Craton was then intruded by a previously unrecognized suite of biotite-bearing granitoid rocks between 1.66 and 1.55 Ga, not recorded elsewhere in the region, and was later the site of emplacement of voluminous granitoid magmatism during the Irumide Orogeny at between 1.05 and 1.00 Ga. Hf isotopic data from zircon in these suites indicate variable influence from cryptic Archean rocks in the lower crustal melting zone of the Bangweulu Block. U-Pb analyses of inherited zircon cores in magmatic zircon in these granitoid rocks, directly confirm the presence of this reworked cryptic Archean basement of the Bangweulu Craton.The age data confirm previously proposed tectonic models for the Mesoproterozoic evolution of central Africa, refuting the presence of a continent-spanning Grenvillian-aged Orogen, including the Kibaran Belt, Irumide Belt and Choma-Kalomo Block of central Africa and connecting with Mesoproterozoic terranes further south along the margins of the Kalahari Craton. The data clearly show that the Proterozoic tectonic evolution of the Bangweulu Craton, which became attached to the southern margin of the larger Congo Craton during the Mesoproterozoic, involved a series of distinct convergent orogenic episodes affecting and reworking its southern (passive) margin. The mismatch in timing of Mesoproterozoic orogenic activity along the Bangweulu Craton, compared to that on the margins of the Kalahari, is compatible with the notion that these continental fragments were not juxtaposed along these Mesoproterozoic belts and in their present-day relative positions at the time. Whether either of these central and southern African cratons did form part of Rodinia, however, remains a matter for debate
