Innovation networks: problems and prospects (Russian case study)

The topologies of innovation network development in Russia are described in this article. Study was conductedin one of the Russian industrial leader JSC Academician M.F. Reshetnev "Information Satellite Systems". Theoretical approaches to the network nature and classification are revealed herein. Some characteristics of innovation network as relatedness, centrality, and intensity were discussed in the article."Information Satellite Systems" has a lot of branch and subsidiaries which form the innovation network of this enterprise. Research methodology consists of head of companies' survey and interview and analyses of open information of firm functioning. Results of research show the vertical hierarchaloriented innovation network with a low-degree of relatedness. Also anchor company ISS has a distinct network landscape with a focus on large vertically integrated, with a low degree of network connectivity, with the unexpressed (weak) links, where a key type of partnership is scientific collaboration with the base (dependent) subsidiary companies, universities and research institutes

Patients with IgA nephropathy exhibit high systemic PDGF-DD levels

Background. Platelet-derived growth factor (PDGF) is a central mediator of mesangioproliferative glomerulonephritis (GN). In experimental mesangioproliferative GN, PDGF-DD serum levels, unlike PDGF-BB, increased up to 1000-fold. Methods. We assessed disease activity in 72 patients with GN, established a novel PDGF-D ELISA and then determined their PDGF-DD levels. In parallel, we studied renal PDGF-DD mRNA expression by RT-PCR. Results. PDGF-DD serum levels in patients with IgA nephropathy (IgAN) were significantly higher (1.67 ± 0.45 ng/ml) and in patients with lupus nephritis significantly lower (0.66 ± 0.86 ng/ml) compared to healthy controls (1.17 ± 0.46 ng/ml), while patients with focal segmental glomerulosclerosis, membranous GN and ANCA-positive vasculitis did not differ from controls. The subgroup of IgAN patients with elevated PDGF-DD levels (27% of samples) did not differ in their clinical features from those with normal PDGF-DD levels. In IgAN patients with repetitive PDGF-DD determinations, most exhibited only minor fluctuations of serum levels over time. Intrarenal PDGF-DD mRNA expression did not differ between controls and patients, suggesting an extrarenal source of the elevated PDGF-DD in IgAN. Conclusions. Serum PDGF-DD levels were specifically elevated in patients with IgAN, in particular in those with early disease, i.e. preserved renal function. Our data support the rationale for anti-PDGF-DD therapy in mesangioproliferative G

Information-analytical systems as a basis of improving the efficiency of risk management

Building an effective system-risk management in an enterprise on the basis of integrated integration of risk management procedures into virtually all enterprise processes is associated with a wide range of tasks. Such integration processes can be simplified by using modern information technologies

Software and hardware platform for testing of Automatic Generation Control algorithms

Development and implementation of new Automatic Generation Control (AGC) algorithms requires testing them on a model that adequately simulates primary energetic, information and control processes. In this article an implementation of a test platform based on HRTSim (Hybrid Real Time Simulator) and SCADA CK-2007 (which is widely used by the System Operator of Russia) is proposed. Testing of AGC algorithms on the test platform based on the same SCADA system that is used in operation allows to exclude errors associated with the transfer of AGC algorithms and settings from the test platform to a real power system. A power system including relay protection, automatic control systems and emergency control automatics can be accurately simulated on HRTSim. Besides the information commonly used by conventional AGC systems HRTSim is able to provide a resemblance of Phasor Measurement Unit (PMU) measurements (information about rotor angles, magnitudes and phase angles of currents and voltages etc.). The additional information significantly expands the number of possible AGC algorithms so the test platform is useful in modern AGC system developing. The obtained test results confirm that the proposed system is applicable for the tasks mentioned above

Model of material and financial flows in the forest industry cluster of the Tomsk region

The main objective of the paper is the modeling of the timber industry complex in the Tomsk region from circular economy and sustainable development point of view. On the basis of the value chain process and the formation of threats along the whole chain nature (forest) - economy - society (consumer) the modeling of products and waste creation has been developed. The large amount of unused waste requires the development of a special regional forestry cluster model using circular economy approach in order to propose best solutions for recycling
