Results analysis of agricultural organizations subsidy

The article presents some issues of the methodology of the study of state support for agricultural production in the aspect of efficiency. The dynamic series of profitability for certain types of products sold by agricultural organizations with and without budget subsidies are used as source data. First, a preliminary analysis and pairwise comparison of the series using nonparametric methods is carried out. Further, in order to use complete information on all the data, the methods of reduction to three variables are applied. In order to compare different methods, the principal component method and autoencoding using a neural network were used. The transformed data was also compared with and without subsidies. Conclusions and practical recommendations on the results obtained, as well as directions for the development of scientific research, are formulated

Structure of a shell made from uranium alloyed with iron and germanium after explosive loading

This paper presents results of metallographic examination of a thick-wall spherical shell from uranium alloyed with iron and germanium. This shell is recovered after low-level explosive loading. Light microscopy, hardness measurement, scanning electron microscopy and X-Ray diffraction study were used to investigate the meridional section of the test shell as this section most completely exhibits the whole variety of structural features associated with explosive loading of the material. Processing, presentation, and analysis of experimental data on volumetric distribution of studied physical quantities were performed with the help of digital panning and color mapping
