UKRAINE'S INTERNATIONAL LIABILITIES ON INITIATION OF MEASURES FOR PUBLIC HEALTH PROTECTION AND THE ROLE OF LOCAL AUTHORITIES IN IMPLEMENTATION OF HEALTH CARE POLICY.

The article examines the international obligations of Ukraine to implement measures to protect public health and the role of local governments in implementation of health policy. Emphasis is placed on Ukraine's implementation of the Sustainable Development Goals being a member of the UN, the Association Agreement between Ukraine and the EU, and the commitment to develop cooperation in the field of health care undertaken by Ukraine, radical health care reform and decentralization reform in Ukraine. The purpose of the article is to determine the role of local governments in implementation of health policy in the context of decentralization reform and the second stage of health care reform in Ukraine, to identify shortcomings in Ukrainian legislation and the practice that lead to violations of regional communities residents' rights for health care and medical aid, as well as violations of the rights of medical personnel for labor.

Formation mechanisms of nano and microcones by laser radiation on surfaces of Si, Ge, and SiGe crystals.

In this work we study the mechanisms of laser radiation interaction with elementary semiconductors such as Si and Ge and their solid solution SiGe. As a result of this investigation, the mechanisms of nanocones and microcones formation on a surface of semiconductor were proposed. We have shown the possibility to control the size and the shape of cones both by the laser.

Exciton quantum confinement in nanocones formed on a surface of CdZnTe solid solution by laser radiation.

The investigation of surface morphology using atomic force microscope has shown self-organizing of the nanocones on the surface of CdZnTe crystal after irradiation by strongly absorbed Nd:YAG laser irradiation at an intensity of 12.0 MW/cm2. The formation of nanocones is explained by the presence of a thermogradient effect in the semiconductor.

Two-stage model of nanocone formation on a surface of elementary semiconductors by laser radiation.

In this work, we study the mechanism of nanocone formation on a surface of elementary semiconductors by Nd:YAG laser radiation. Our previous investigations of SiGe and CdZnTe solid solutions have shown that nanocone formation mechanism is characterized by two stages. The first stage is characterized by formation of heterostructure, for example, Ge/Si heterostructure from SiGe solid solutions, and the second stage is characterized by formation of nanocones by mechanical plastic deformation of the compressed Ge layer on Si due to mismatch of Si and Ge crystalline lattices.
