  • Stabilographic functional diagnostics in elite sports

      The purpose of investigation is to examine the effect of adaptation to difficult-house physical stress on the regulation of the vertical posture of man. For the analysis of the ability to maintain a vertical position used stabilographic hardware-software complex "Stabilan-1-02" (JSK Rhythm ", Russia). The ability to maintain a vertical position was evaluated in two static positions: 1) the main stand (OS) in the presence and absence of visual information, and 2) dip (PP) in the presence of visual information. Revealed that an increase of physical performance ability to maintain balance in static positions, especially in the complicated conditions (deprivation of visual information and static muscle tension) increases.

  • Methods of measurement of small inductors for radio systems on a chip

    Technique for measurement of inductances (L) about 1 nanohenry or less one, is discussed. Two measurements of inductance L are executed. First one is executed for stub length l0, another - for stub length, shortened into N times. Formula for calculation of unknown inductance’ error has been obtained, where determination of unknown L with error closed to meter error has been succeeded by choice of parameters. It is shown that required measurement’s error of initial stub length for N=2 and N=5 is in tens micrometers’ range. Techniques for error’s diminishing have been considered. Estimation for basic stub length of 6,6 mm and 8,3 mm for N=2 and N=5 respectively has been executed.

  • The potential of using biogas in the agricultural region

    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 method of extension operating frequency range of source and emitter voltage follower

    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.

  • Theoretical features of management of organizational conflict in modern management

    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.
