Newton's method of solving a system of nonlinear equationsThe concept of a system of nonlinear equations, the stages of solving the problem, the geometric interpretation of the solution of the equation and the concept of iterative processes are given and their application is shown in the examples. The problem of numerical solution of a number of practical problems consisting of a system of nonlinear equations is considered. There are a number of approximate computational methods for solving systems of nonlinear equations, including Newton's method. Using these methods, a number of specific practical problems were solved, a computational algorithm and a block diagram were developed. An approximate method of finding the true roots of a system of nonlinear equations is given, based on examples, graphs are used in the form of results, and appropriate conclusions are drawn

Comparisons the numerical results of the turbulence model for the problem of rotating tubes inside a dynamic hydrocycloneThe article provides a comparative analysis of turbulence models by numerically simulating a swirling flow inside a rotatable pipe. To solve this problem, the Reynolds averaged non-stationary Navier-Stokes equations in a cylindrical coordinate system were used. To find the Reynolds voltage, the turbulence model was used the most popular semi-empirical turbulence model. Comparison is made between models of different approaches to turbulence SSG / LRR-RSM-w2012 and νt-92. The numerical results obtained on the basis of turbulence models are compared with the well-known experimental results of Reich and Beer (1989)

Assefoetida l., by the method of high-performance liquid chromatographyUzbekistan is a country endowed with a variety of medicinal plants with strong potential for therapeutic application, Ferula assefoetida l. is called ferula is one of the most popular medicinal herbs. It is important active ingredient responsible for the biological activity of ferula, through the major activity is anti-inflammatory. This analysis was aimed to determine analysis compound of ferulic acids analysis using high performanceliquid chromatography (HPLC), LC-20 Prominence, Shimadzu, column C-18 250 х 4,6 mm, 5 mcm; acetonitrile: acetic acid: aqua bides as mobile phase, flow rate 1 ml/min and detection at 320 nm. Thus the analytical method using HPLC for ferulic acid were feasible for quantitative analysis. As a result of the research, the content of dry extract was 0,01% of the content of ferulic acid.
