Silica Sol Binder for Building Materials
The use of sodium silicates as gluing binders is limited by the fact that the tensile strength of these bindings
is below 50 kg/cm2, and the fact that the bindings remain water-soluble till the annealing temperature of +250Β°C. Besides, when heated to +160Β°C , these gluing binders distend. Gluing binders based on SiO2 sold or gels exhibit tensile strength above 500 kg/cm2, are insoluble in water at the annealing temperature of +150Β°C and do not distend during heating

the method of self-propagating high-temperature synthesis from a mechanochemically activated
mixture of tungsten oxide, metallic magnesium, carbon black and CaCO3. The phase composition
of the formed materials was shown to depend on the amount of CaCO3. The catalytic properties of
the materials were tested in the hydrolysis-hydrogenation of cellulose to ethylene glycol (EG) and
1,2-propylene glycol (PG). It was established that in the presence of WnC the main products of the
reaction were EG and PG with a ratio of PG/EG β 1.5-1.8. The deposition of nickel nanoparticles
on the WnC surface increased the reaction rate and product yields. The maximum total yield of diols
was 47.1 mol. %
Implementation Of The Financial Planning System Using The Intra-University Information
The case-type article describes the experience of implementing financial planning in Volgograd State University. It describes an approach to solving the practical problem of improving university internal efficacy. The gist of the used budgeting-based approach to university financial management is described alongside with its technologies. The article suggests a new methodological basis for designing the process of planning and budgeting the universityβs financial and economic activities as well as a method of creating infrastructure for gathering primary indicators, calculating the indicators of business finance-related matters, as well as for the automatization of planning and budgeting process. The authors identified the place of financial planning in the process of formulating and implementing university development strategy. There was chosen a model for planning and budgeting, local documents were worked out to regulate the planning and budgeting process, architecture of complex information system was designed to support planning and budgeting processes. The article enumerates financial responsibility centers, types of plans, income and costs included into the plans. Budgets of the financial responsibility centers were formed. As a result of the research, the authors proved the efficacy of a mixed planning and budgeting model for a regional autonomous university, as well as the feasibility of using its own information support system for the financial planning process.Π‘ΡΠ°ΡΡΡ ΠΎΡΠ½ΠΎΡΠΈΡΡΡ ΠΊ ΠΊΠ°ΡΠ΅Π³ΠΎΡΠΈΠΈ ΠΊΠ΅ΠΉΡΠΎΠ², ΠΎΠΏΠΈΡΡΠ²Π°Π΅Ρ ΠΎΠΏΡΡ ΡΠ΅Π°Π»ΠΈΠ·Π°ΡΠΈΠΈ ΡΠΈΠ½Π°Π½ΡΠΎΠ²ΠΎΠ³ΠΎ ΠΏΠ»Π°Π½ΠΈΡΠΎΠ²Π°Π½ΠΈΡ Π² ΠΠΎΠ»Π³ΠΎΠ³ΡΠ°Π΄ΡΠΊΠΎΠΌ Π³ΠΎΡΡΠ΄Π°ΡΡΡΠ²Π΅Π½Π½ΠΎΠΌ ΡΠ½ΠΈΠ²Π΅ΡΡΠΈΡΠ΅ΡΠ΅.

Vacuum performance of a carbon fibre cryosorber for the LHC LSS beam screen
A new carbon fibre material was developed at the Institute of Solid State Chemistry and Mechanochemistry at the Siberian Branch of the Russian Academy of Science (SB RAS) to meet the large hadron collider (LHC) vacuum chamber. The material must have a large sorbing capacity, a certain pumping speed, a working temperature range between 5 and 20K, a low activation temperature (below room temperature), a certain size in order to fit into the limited space available and it should be easy to mount. The vacuum parameters of the LHC vacuum chamber prototype with a carbon fibre cryosorber mounted onto the beam screen were studied in the beam screen temperature range from 14 to 25K at the Budker Institute of Nuclear Physics SB RAS. This carbon fibre material has shown sufficient sorption capacity for hydrogen at operational temperatures of the beam screen in the LHC long straight sections. It is also very important that this material does not crumble and makes a convenient fixation onto the beam screen in comparison to the widely used granulated charcoal. The problem of fluff and ways of reducing the quantity of fluff in the beam channel were studied. The results of these studies show that the carbon fibre material is a possible cryosorber-candidate for use in the LHC and other long vacuum system at cryogenic temperatures. The experimental set-up and results of measurements of the H//2 cryosorption capacity of this carbon fibre material are presented in this paper
