The new benzimidazole-functionalized graphene
material based on graphene oxide (GO) and 3,3',4,4'-
tetraaminodiphenyl oxide (TADPO) was obtained
under one-step hydrothermal synthesis conditions.
According to IR spectroscopy and elemental analysis,
as a result of the reaction, benzimidazole (BI) rings are
formed, and the mass content of nitrogen is 12.3%.
The new graphene material is characterized by
excellent electrochemical efficiency in a threeelectrode
supercapacitor. As a result of the redox
activity of BI cycles the specific capacitance reaches
286 F/g at the scan rate of 2 mV/s, which is
substantially higher than the reduced graphene oxide
(RGO) sample obtained under similar conditions
without using TADPO (159 F/g at 2 mV/s)
Rational and efficient use of natural resources is an important element of sustainable development. Waste is a significant loss of material and energy resources. Recycling and disposal of waste can be a cause of pollution, harmful substances and infections on people. Index of waste production is closely linked to the level of economic activity in the country and sums up the structures of production and consumption that are formed in the society. Reduction of capacity size of waste production is a measure of promotion of the economy sector to less material-intensive structures of production and consumption. Phytogenic wastes are mostly formed in the timber industry, and also are pollutant source of environment. Continuing production and accumulation of waste is a serious environmental problem. The main reason for these circumstances involves insufficiency of power in added-value wood processing, that increase the problem of integrated utilization of low-grade wood, small wood and demolition wood. As a result, the main competitive products in the timber complex of the Krasnoyarsk Territory are industrial wood and roundwood. Solution to these topical issues of optimum use of the resulting waste in the Krasnoyarsk Territory needs to be solved with the help of mathematical modeling of process optimization of recycling lumpy plant waste. Rational use of lump plant waste is one of the most serious and, unfortunately, unresolved problem

Grain is the strategic importance and is the basis for
food security. The gross national product share of
grain and its products is about 10-15%. It always
stands out from other types of raw materials, as used to
produce the most massive daily foods. When selecting
cultivation technology agricultural crop agronomist
has at its disposal a database of more than a hundred
times-personal of alternative technologies for each
crop. Prior to the decision-maker (DMP) is the task of
specific criteria to select the most suitable for the owners,
climatic zone of technology cultivating culture.
These circumstances explain the relevance of in-depth
research of economic and mathematical models and
methods of analysis and evaluation of the economic
efficiency of technologies of cultivation agricultural
crops. The possibility of developing a set of mathematical
models and methods for multi-criteria analysis and
assessment key technologies of cultivation of agricultural
crops
The article examines the process of secularization of
Church property in the history of the world. Special
attention is paid to the assumptions of the preparation
of secularizing reforms in the Russian state since the
policy of Joann III. We address the relationship
between Church and state in the field of Church lands
and ecclesiastical jurisdiction authorized in Stoglav in
1551, and in the judgment of the Council estates in
1581 and 1584. The article studies the reasons, under
which it became necessary, in conditions of the
emerging absolutism, to limit the Church's estates; the
ecclesiastical jurisdiction in this connection, there was
issued the national Code – “Sobornoye ulozheniye” of
1649. The study discusses the limitation of economic
and administrative privileges of the Church in
accordance with the Council code of Tsar Alexei
Mikhailovich. The article focuses on the
administrative and financial functions of the Monastic
Order. We have also made a distinction, and there are
differences in the powers between the Monastic
Orders 1649 and between recreated Monastic Order in
1701. The article discusses the mission of the Church
reform of Peter I the Great and the results of this
reform, which prepared the legislative framework for
the secularizing reforms of Catherine II the Great
In connection with the crisis in the global economy, the article suggested and discussed some conceptual issues concerning the implementation of measures in the budget process of government programs as a tool to improve the efficiency of budget expenditures, which was the procedure for design of public programs, approved a list of them, formed the first analytical cost sharing these programs
In connection with the crisis in the global economy, in this article we have suggested and discussed the conceptual issues concerning the implementation of measures in the budget process of government programs as a tool to improve the efficiency of budget expenditures, where the procedure for design of public programs was shown; we also have approved the list of the programs and formed the first analytical cost sharing for these programs
The accepted model of the access control is realized with the monitor of safety in the protected automated information system. Models of safety are considered, as a rule, as a system which is a single whole and has the uniform monitor of safety. Nevertheless, the architecture of the real automated information systems and processes of their functioning can be characterized by distribution. The distributed automated information system consists more than of one local segment representing isolated set of subjects and objects of access. In the distributed system local segments can be realized both on the basis of discretionary, and on the basis of mandatory models of safety (i.e. to be diverse). One of directions of a safety in this case is realization of the general monitor of the safety providing the uniform (coordinated) policy of access control. For safe interaction of patchwork systems it’s necessary to bring them to a single model. Hence, while the integration of information systems the problem of their interaction becomes persistent. Thus in the systems processing the information of a various level of confidentiality, it is necessary to realize mandatory access control. In given clause the mandatory policy of the safety presented by classical model of Bell-LaPadula, is described by the elements of classical model of Harrison-Russo-William. Using the mechanisms of change of a matrix access the opportunity of assignment and change of confidentiality marks is described and the observance of safe practices within the limits of mandatory access control is analyzed. The safety of application of the given approach has been proved. The perspective direction of research has been defined
The main diseases of lactating cows occur in the first
two months of lactation, i.e. during the production
peak of productivity. They are caused by the changes
in metabolism during the transition period, which are
not supported by adequate changes in the organization
of feeding, or rather sufficient to ensure cows with
nutrients, which causes a number of closely related
diseases. To allocate any of them is not possible, as
their manifestation depends on a number of reasons,
and depending on situation may prevail one or the
other. Among the most common diseases, there are
ketosis, milk fever (paresis of maternity), dysplasia of
the abomasum, acidosis, mastitis, endometritis,
laminitis and leukemia. These diseases cause the
greatest problems in herds with high productivity, and
are caused by changes in metabolism in cows in the
transition period and the inability to properly feed the
animals at this time. To identify the causes of these
diseases we do not need to study each of them
individually - it is enough to deal with the peculiarities
of metabolism. This period includes the month before
calving and the first or second month of lactation, but
the most important are 3 weeks before calving and 3
weeks later. In order to prevent metabolic disorders
there were developed and tested feed for feeding cows
before calving and immediately after calving. Their
effect was studied on milk production and health status
We have developed the "Gidrogemol" preparation for correction of micro ecological processes in the gastrointestinal tract of calves. We have also established preventative efficacy of the preparation for acute intestinal infections of newborn calves
