Tverberg plus constraints

Many of the strengthenings and extensions of the topological Tverberg theorem can be derived with surprising ease directly from the original theorem: For this we introduce a proof technique that combines a concept of "Tverberg unavoidable subcomplexes" with the observation that Tverberg points that equalize the distance from such a subcomplex can be obtained from maps to an extended target space. Thus we obtain simple proofs for many variants of the topological Tverberg theorem, such as the colored Tverberg theorem of Zivaljevic and Vrecica (1992). We also get a new strengthened version of the generalized van Kampen-Flores theorem by Sarkaria (1991) and Volovikov (1996), an affine version of their "j-wise disjoint" Tverberg theorem, and a topological version of Soberon's (2013) result on Tverberg points with equal barycentric coordinates.Comment: 15 pages; revised version, accepted for publication in Bulletin London Math.

Compliance with corporate governance principles as element of Russian economy investment attractiveness

Over the last few years, the concept of corporate governance in relation to Russian economic realities has been used relatively recently. The concept of corporate governance in the economic practice of Russia was synonymous with production management in 1990-2000 At the same time, "good corporate governance" is a set of activities of public companies in order to ensure high demand for their shares and debt securities from portfolio investors. Corporate governance is a means of trust development both in individual companies and in the stock market of the country as a whole, which is of great importance for long-term investment attraction.  According to various global ratings of the countries (for example, to the rating of the financial conglomerate Morgan Stanley, the Russian stock market is classified as an emerging market that provides increased investment returns. The article attempts to determine the main priorities of institutional investors for corporate governance in Russia. The authors come to the conclusion that the development of the corporate governance system is one of the key factors increasing the investment attractiveness of Russian companies. Government regulators take measures to create corporate governance standards, one example of which is the recommendation to use the Corporate Governance Code approved by the Board of Directors of the Bank of Russia in 2014. In fact, the article highlights both positive and negative trends in the Russian practice of corporate governance. It provides the results of opinion polls among investors, which reveal their motivation to make investment decisions in the Russian market

High pressure pre-treatments promote higher rate and degree of enzymatic hydrolysis of cellulose

The effect of high pressure (HP) pre-treatments on the subsequent enzymatic hydrolysis of cellulose from bleached kraft Eucalyptus globulus pulp by cellulase from Tricoderma viride was evaluated. Pressure pre-treatments of 300 and 400 MPa during 5–45 min, lead to both an increased rate and degree of hydrolysis, reaching values ranging from 1.5- to 1.9-fold, quantified by the formation of reducing sugars. Both the pressure and time under pressure influenced the enzymatic hydrosability of the cellulosic pulps, with the former being more important. The results indicate that the pressure pre-treatments promoted an increased accessibility of cellulose towards cellulase in the cell wall. The results obtained open promising possibilities, to contribute to overcome conventional limitations of enzymatic cellulose hydrolysis for the production of fermentable glucose, for the production of second generation bioethanol and chemicals by enhancement of both rate and yield of hydrolysis. The results are also of interest for the preparation of “pressure engineered” celullose with incremented tailored hydrolysis patterns
