Methodological support for forensic science in the USA and Ukraine: A comparative study.

The significant potential of proper methodological support in solving key tasks of forensic expert activity is noted. The procedure for certification and state registration of forensic examination methods introduced in Ukraine is analyzed. The composition and procedure for the activities of the advisory bodies of the Ministry of Justice of Ukraine which determine the relevance and priority of forensic examination research are investigated.

Areas of modernization of the system of training and certification of forensic experts in Ukraine based on the adaptation of foreign experience.

Unlabelled: The article is devoted to the study of the existing system of training and certification of forensic experts in Ukraine and to the provision of proposals for its modernization, taking into account the positive experience in the field of forensic science of the USA, UK and some countries of the European Union. In Ukraine, the procedure for the training and certification of forensic experts is determined by ministries and other central executive authorities, which manage state specialized institutions that carry out forensic activities. A study of foreign experience in the training and certification of forensic experts made it possible to identify general and specific elements, sustain the benefits of the implemented measures, and formulate priorities and guidelines.

Alien Algae Species Invasions in Humic Rivers within Weakly Human Impact Basin.

Increasing anthropogenic influence and climate change are leading to significant transformations in living conditions for indigenous representatives of aquatic communities. The problem of alien species invasions is actively discussed in the example of large rivers and water reservoirs, but medium and small rivers with weak anthropogenic influence have been insufficiently studied in this aspect. With the help of analysis of literary data and the results of our own long-term observations of phytoplankton using morphological and molecular genetic methods in some left-bank Volga tributaries, we identified six invasive species of different taxonomic groups of algae, with a predominance of diatoms.

Bioactivity Features of a Zn-1%Mg-0.1%Dy Alloy Strengthened by Equal-Channel Angular Pressing.

The structure, phase composition, corrosion and mechanical properties, as well as aspects of biocompatibility in vitro and in vivo, of a Zn-1%Mg-0.1%Dy alloy after equal-channel angular pressing (ECAP) were studied. The structure refinement after ECAP leads to the formation of elongated α-Zn grains with a width of ~10 µm and of Mg- and Dy-containing phases.
