Bstract: In the present work the capillary flow of magnetic fluid in a single cylindrical capillary and in a porous medium under the action of a non-uniform magnetic field is studied experimentally. The dynamics of the capillary rise has been considered. It has been demonstrated that the non-uniform magnetic field with upward directed gradient accelerates the capillary rise; contrary, the non-uniform magnetic field with downward directed gradient decelerates the capillary rise. The obtained results have been analyzed. The method of the study of magnetic fluid capillary rise based on the use of magnetic measurements has been proposed. The potential applications to the porous materials characterization technique have been discussed.

The work outlines a method of constructing an approximate solution of the differential equation with the initial data obtained in the experiment (empirical functions), which are known with some errors. In such statement the problem belongs to the class of incorrect mathematical problems and often occurs, for example, in mathematical models of physical phenomena using measurement results of field experiments. This is due to the relevance of the research. To obtain the approximate solution of this problem requires construction of appropriate regularization algorithms based on the methods of the theory of functional analysis and ill-posed problems. In the present work is the construction of the approximate solution of odes with specified boundary conditions, are the so-called singular integrals. This allows you to put in the original equation Fredholm integral equation of the first kind and to find its numerical solution. This uses a machine approximation of functions and their derivatives corresponding singular integrals and regularization method convergence of the sequence of approximate solutions, which implemented the so-called generalized inverse operators. Built in the end, a computational model allows to obtain a stable solution of ill-posed problems.

The article discusses the state of adaptation mechanisms in adolescent boys, taking into account intersystem approach. Studied the correlation of the vegetative regulation of heart rate and levels of cortisol, testosterone, estradiol in blood serum of adolescents Russian and Turkmen nationality. The Russians have installed more adolescents expressed positive inter-correlation of cortisol with indices of LF, VLF, AMo, SI and negative - with SDNN, RMSSD, pNN50, HF, while the Turkmen boys similar relation was less pronounced. Relationship testosterone levels in both population groups were positive with heart rate, AMo, SI, VLF and negative - with SDNN, RMSSD, pNN50, HF. The established relationship of estrogen with HRV reflects the peculiarities of the heart rhythm regulation among Turkmen boys, probably due to the relatively low estradiol level mediated the influence of estrogen on the cardiovascular system (positive relationship with HR, SI, VLF, and negative - with SDNN, RMSSD, pNN50, HF).
