Concentration of Ownership in Russian Industry: Firm-Level Evolution

The paper describes dynamics of ownership concentration in Russian manufacturing, and factors of the dynamics against the background of economic growth of 2000s. The first signs of stock ownership de-concentration in some companies during 2005–2009 were revealed. Empirical analysis of determinants of changes in concentration was implemented. Significant positive factors of this decline are companies’ entry to securities markets, their work in competitive environment, and share of foreign investors. Negative influence of propensity to future investments and of the share of Russian owners was also found out. The study is based on the data of two rounds of monitoring of about 1000 large and medium-sized companies conducted by the Institute for Industrial and Market Studies from HSE in 2005 and 2009. Binary and ordinal regression models were used.stock ownership, concentration of ownership, corporate control

Russian Manufacturing Revisited: Industrial Enterprises at the Start of the Crisis

The paper is based on the findings of a major project by the Higher School of Economics Institute for Industrial and Market Studies (IIMS) to monitor competitiveness of manufacturing enterprises. The study focuses on the drivers and dynamics of business competitiveness, including changes in firms’ behavior during the period before the crisis (2005-2008). The primary issue was to find out what firms and to what extent succeeded in capitalizing on the strong economic growth before the crisis to catch up with their competitors and gain a sustainable competitive position in the market. What was driving output increases and enhanced production efficiency? What were the impediments to this process

Thermal decomposition of natural polysaccharides: Chitin and chitosan

The results of the thermal analysis of shrimp’s chitin and chitosan have been presented (samples of polysaccharide differed by the deacetylation degree have been studied). The thermal analysis has been carried out by differential thermogravimetry and differential scanning calorimetry. Activation energy of process of chitin and chitosan thermal destruction has been calculate

Properties of aqueous dispersion of chitosan and chondroitin sulfate complex derived from aquatic organisms

Investigation of production of chondroitin sulfate, chitosan and polyelectrolyte complexes based on them received from the local marine raw materials is relevant from the point of view of developing a comprehensive waste-free technology for natural raw materials processing. The objects of study are chitosan derived from the shell of the Kamchatka crab Paralithodes camtschaticus and chondroitin sulfate derived from cartilage of salmon Salmon salar. To determine the surface tension of polyelectrolyte complex solutions and dispersions the Wilhelmy method has been used, the effective radius of particle dispersion has been calculated by light scattering, measurements of effective viscosity have been carried out under shear deformation. The conditions of formation, surface and rheological properties of the chitosan and chondroitin sulfate complex extracted from aquatic organisms in the Barents Sea have been studied. Obtaining conditions and molar ratios of these polyelectrolytes in which the aqueous dispersion of the complex remains stable for a long time have been established. It has been found that by addition of chondroitin sulfate solution to chitosan solution in molar ratios of 1 : 3; 1 : 6 the dispersion of the polyelectrolyte complex stable for 2 to 3 days has been formed. The polyelectrolyte complex dispersions behave as non-Newtonian pseudoplastic liquid. When the molar ratio of the mixed solution is 1 : 1 (regardless of the sequence of mixing) suspension of the polyelectrolyte complex has been formed, then there is precipitation. Equilibrium surface tension of the aqueous dispersion of the polyelectrolyte complex is higher than that of solutions of chondroitin sulfate and chitosan. The effective radius of particles in the complex dispersion has been determined. The effective radius of the particles in the complex dispersion depends on the molar ratio of chondroitin sulfate : chitosan. A qualitative scheme of formation of polyelectrolyte complex from chitosan and chondroitin sulfate as an insoluble precipitate and as a form of stable aqueous dispersion has been proposed. Aqueous dispersions based on chitosan and chondroitin sulfate complex can be used to stabilize suspensions, emulsions, to create foods with a therapeutic and prophylactic properties
