With the aim of studying the features of the vegetative components of cardiac activity in the period of functional stress of the body, that are interesting for study of adaptive changes in the human circulatory system, there has been studied the heart chronotropic response to the paired somato-vegetative cardiac reflex caused by a modified breakdown Aschner-Danini in first year military servicemen and students of the Syktyvkar State University in conditions of relative rest and after physical loading, samples Martin-Kushelevsky. With use of the method of electrocardiography in the second standard lead, there were recorded RR-intervals before and after functional tests. It has been found that in the servicemen with the heart heterogeneous chronotropic function which bodies adapted to new environments, vagal samples in the body state of relative rest caused a bigger heterogeneous chronotropic response of the heart than in the students adapted to external conditions. After the subjects underwent exercise loading, the heart response to induced coupled cardiac reflex was unidirectional and more pronounced than at rest. The results indicated increased influence of the vagus on the heart work in conditions of the body mobilization. Associated vagal test combined with the exercise loading is the method of choice in evaluation of the autonomic system regulating the circulation homeostasis in conditions of high requirements to the body.

In this paper, we introduce an approach of increasing the degree of integration drift heterobipolar transistors. This approach is based on the formation of desired heterostructure configuration, its doping carried out by diffusion or implantation of necessary areas and optimizing the annealing and/or radiation-induced defects. © 2015 Elsevier Ltd.

A method of constructing the equation of state of a simple thermodynamically equilibrium mixture is proposed. The method is based on the hypothesis of additivity of the species volumes. The equilibrium state is determined by the conditions of equality of pressures, temperatures, and velocities of the species. The mixture is described by the model of interpenetrating and interacting continua, which takes into account the gas presence in pores. The equations of state of the mixture and all species, including the gaseous species, are presented in a unified manner (in the form of the Mie-Grüneisen equation). Presentation of functions in the form of Taylor series yields relations that allow the parameters of the equation of state of the mixture to be expressed via the corresponding parameters and mass fractions of individual species. Numerical calculations of shock wave loading and isentropic expansion are performed for solid and porous copper, tungsten, tungsten-copper mixture, and tungsten-nickel-copper mixture. It is demonstrated that the resultant equation of state of the mixture ensures a fairly accurate description of multispecies media with shock and expansion waves propagating in these media. © 2012 Pleiades Publishing, Ltd.

This article discusses some general issues related to the definition of globalism as a special branch of science, its subject, status, terminology, the situation in the modern sciences. The concept "globalization" is included in a turn and is widely adopted in connection with discussion among scientists, politicians, journalists of crisis of 1997-1999 of the XX century, discussions about prospects of the world and the certain countries. For the first time the term was used in 1967 for designation bigger, than before depth of the international integration.

A new method for calculated estimation of the speech signal base frequency, on the basis of the minimal correlation coefficient discrepancy, is developed. This method of estimation of the base frequency was compared with the amplitude, correlation and spectral methods and the wavelet method. © 2012 by Begell House, Inc.
