MATHEMATICAL PLANNING METHOD APPLICATION IN THE DEVELOPMENT OF VAGINAL SUPPOSITORIES FOR VAGINITIS TREATMENT AND PREVENTION

This article examines the influence of the parameters of the coating teeth of the discrete drum on the quality of the OE yarn. Based on the analysis of the conditions for retention of fibers by the covering teeth of the discrete drum, equations were obtained to determine the angle of inclination of the teeth. To determine the effect of the coating parameters of the discrete drum teeth on yarn quality, experiments were performed using the Full Factor Experiments mathematical planning method, and a regression equation was obtained for each variable. As a result, the optimal values of the discretization drum coating teeth of the OE spinning machine were determined.

When selecting the compositions and studying the properties of the activated mineral powders based on superacid fly ash, mineral and organic activating agents, the computer modelling was performed. The activated mineral powders compositions corresponding to the properties of GOST 32761 2014 requirements to the MP-1 activated mineral powders of carbonate rocks were selected using the experiment mathematical planning method. When processing the experimental data for obtaining the adequate mathematical model, optimizing the compositions and constructing the graphical dependencies, the Maple package was used. The software for the personal computer including the algorithm and se-lection program of the activated mineral powders compositions was developed. The software makes it possible to automate the calculation of the activated mineral powders formulas with the specified technical properties.

The paper presents the results of theoretical and experimental studies aimed at optimizing the decortication process of industrial hemp stems. In order to achieve this goal, physical and mechanical properties of industrial hemp straw stems were investigated, with the choice of the main quality indicator - diameter, which directly influences the bast output. Also, with the help of mathematical planning of the experiment, the optimal treatment mode for the stems of industrial hemp with clearing of wood of 5-6% was calculated.
