Among the dynamic problems of viscoelasticity, one should single out the problem of the oscillation of viscoelastic rods, the solutions of which are reduced to the Volterra integro-differential equation of the second kind. The solution of this equation requires specifying the analytical form of the kernel, or is solved by various numerical methods. In this paper, we propose an approximate solution to this integro-differential equation for arbitrary nuclei with low viscosity.
Многочисленными исследованиями показано, что установление правильного суточного ритма температуры тела происходит к 1,5-2- месячному возрасту. Г ипоксия, внутричерепная травма, инфекции, поражающие центральную нервную систему, как и аномалии ее, могут быть причиной нарушений функции центрального аппарата терморегуляции.

Blood pressure studied on 250 school children. It was found that clearly insufficient attention is paid to the early detection of hypertension and the identification of risk factors. It was found that for the correct diagnosis of arterial hypertension on an outpatient basis, it is necessary to clearly determine the correspondence of actual blood pressure with a value of 95%o for the corresponding sex, age and height. While daily monitoring of blood pressure is the most informative method for the diagnosis of arterial hypertension in pediatrics.
