The article examines the development of biogas production in the Altai region. Indicates the need for wide implementation in ho-agricultural practice of farms renewable energy.  Provides information about the main raw materials and specific yield volumes of fuel out of it. Argued that there is a potential for the construction of facilities for the production of biogas based on large and medium-sized livestock operations. This can provide up to 20-25% of the demand in the Altai region gas fuel. It is noted that the implementation of this project requires coordination of government support measures with the mandatory inclusion of livestock facilities for biogas in the construction or reconstruction of livestock enterprises. Also priority for biogas energy in the Altai region called the creation of biogas plants with low capacity. They can be used by individuals to meet the challenges of energy supply and heating. Refers to the importance of their implementation in some areas Altai region.

The paper discusses the features of method of extension of circuit’s operating frequency range of the source and the classical emitter voltage follower (VF). The features of this method based on the effect of the mutual compensation of the parasitic impedances are considered. Problem of improving operation speed of VF with output capacitance and reducing the time of establishment of transient at pulsed input voltage are discussed.
The simulation results of VF in Cadence on model of SiGe integrated transistors are given. This shows that with capacitive load high-frequency cutoff, the time of establishment of transient and the slew rate improved to tens - hundreds of times. 
The results of investigate complement of methods of improving operation speed of the classical stage with a common drain and common collector.

Are considered method of reducing one of the most essential components of the voltage offset Uvo operational amplifiers (op-amp), executed on classical architecture with current mirrors, which is linked to the change current gain of base (β) bipolar transistors in conditions of temperature and radiation effects.
To solve this problem in the basic architecture of op-amp is entered special corrective multipole, which will provide low-current asymmetry in coordination of input differential stage (DS). The method is applicable to op-amp, which is inexpedient to make any adjustments to the original structure of the DS. 
The analytical expressions determining basic parameters the compensation circuits Uvo, and also shows the tabular data that simplify the choice of standard functional components of precision op-amps.

The article covers the period from XVII to XIX century in the development of art education, when it loses its elitism and becomes massive. Identifies three major trends that have influenced the formation of pedagogical training bases of graphic activity and color in professional artistic training: academic training system, physics color and secondary school. The period and the basic principles of the formation of European and Russian art training. Determined by the stage of the formation of the world system of artistic training.

Article is devoted to aspects of management, aimed at investigating the nature of organizational conflict in order to identify the causes and possible management. Relevance of the topic emphasized by the fact that the study of conflict, its causes, and the methods and means of management emerged relatively recently and now, when the Russian economy is going through a stage of radical reform, this aspect of management is of interest for many researchers. Since the conflict in terms of joint activities of people are able to reduce labor productivity, it is necessary as soon as possible to anticipate. Particularly noteworthy are the management of organizational conflicts, as in the current economic development organization is a key participant in the economic relations and the conflicts that arise in this subject in need of early detection and effective management.

Keywords: organizational conflict resolution, management, conflict management, the concept

  This article presents an agent-based computational model of civil violence. In the model a central authority seeks to suppress communal violence between two warring ethnic groups. To describe model UML diagrams are presented. Article also shows a number of experiments with model which shows such benefits of model as guiding data collection, revealing dynamical analogies, discovering new questions and decision support in crisis situations.
