Abstract:

In consideration of correlations among hardness, chemical composition, grain size, and strength of carbon steel, a new nondestructive testing technology (NDT) of inferring the carbon steel strength was explored. First, the hardness test, chemical composition analysis, and metallographic analysis of 162 low-carbon steel samples were conducted. Second, the following works were carried out: (1) quantitative relationship between steel Leeb hardness and carbon steel strength was studied on the basis of regression analysis of experimental data; (2) influences of chemical composition and grain size o

Abstract:

This article presents the morphological structure, classification of biologically active substances, and chemical composition of plants of the genus Ferula, growing in Kyrgyzstan. Plants of the genus Ferula have long been used in folk medicine, as they contain biologically active compounds. The variety of biological properties of substances found in different types of ferula has prompted researchers to more carefully study their chemical composition. To date, chemotaxonomic summaries have been compiled for all major families of higher plants, but insufficient knowledge of the chemical composit

The aim of this study was to propose a scoring algorithm to rank the nutritional value of EVOO samples, considering their chemical composition in macro- and micronutrients and their sensitivity to oxidation phenomena.
