European Cyber Security System
Nowadays computer networks are widely spread in all spheres of human life.
That is why the problem of cyber security of mankind is of great importance. Today,
the European Union makes efforts to guarantee network safety in Europe by means of
increase its member states in power and international cooperation in cyber security,
including non-member countries, to prevent cyber crimes. Striving to join the
European Union, Ukraine is involved in the process of providing cyber security. This
paper examines the main strategies of EU standards in cyber security to be followed
by Ukraine as one of European countries

An experimental study of the influence of a thermosyphon filling ratio on a temperature distribution in characteristic points along the vapor channel height
Results of experimental studies of heat transfer in a thermosyphon illustrating the influence of the filling ratio and the heat load on the temperature distribution in the vapor channel, evaporation and condensation zones are presented. The thermosyphon was made of copper and was 161 mm high with side walls 1.5 mm thick, bottom cover 2 mm thick, an internal dimmer of the evaporation part of 54 mm and an internal diameter of the vapor channel of 39.2 mm. Based on the results of experimental studies, temperature dependences were established in the characteristic cross sections of the thermosyphon on the heat flux value supplied to the bottom cover. In addition, a well-appearing thermosyphon self-regulation property has been found β the growth of the heat load in the evaporation zone in the range from 1940 to 7685 W/m{2} does not lead to a decrease in the heat removal intensity from the heat-release region
