The basic patterns of the distribution, migration and accumulation of radionuclides in the bottom sediment of the Baltic Sea
This paper focuses on the impact of certain factors on the contemporary distribution of natural (226Ra, 232Th, 40К) and anthropogenic (137Cs, 60Co) radionuclides in the sediments of the Baltic Sea. The results of the study suggest that the distribution of 137Cs is determined by the content of hydromica of silty-clay and clay grain-size fractions, while radiocaesium is mainly accumulated by silty fractions. The accumulation of 226Ra by bottom sediments is mainly determined by the pH geochemical barrier...
Comparative evaluation of the biological effect of native and synthesized peptides
... cost and complexity of isolating native peptides for use in pharmaceuticals, synthetically produced peptides are increasingly being used in dietary supplements. The aim of the research is to confirm the similarity and biological activity of synthesized peptides compared to native peptides. Synthesized and native peptides from bovine colostrum with the code names T1.1 and mpT2 were used as the objects of the study. The peptides were synthesized using the solid-phase method. Peptide T1.1 is ...
