The explosion danger in all industries where explosive atmospheres generated by the mixture of combustible dusts or flammable gases with air may form, must be treated as a major hazard, as the explosions that may occur can seriously affect both health and safety people, as well as the environment. It is therefore necessary to assess the explosion risk and to establish appropriate measures to reduce it to acceptable levels in accordance with the requirements of the European Directives. An essential element in the assessment of the explosion risk for electrical and non-electrical equipment intended for use in potentially explosive atmospheres is the way in which an appropriate normal degree of protection is provided through the equipment housing (protection against touching of dangerous parts inside the equipment housing and protection against the ingress of dust and water inside it). The aim of the paper is to highlight compliance with the requirements of the ATEX Directive, given that this protection is a basic requirement for explosion protection and to present the important elements to be considered for the assessment of the normal degree of protection and the development of harmonized test methods with the requirements of European standards.

Abstract The use of aluminum radiators in heating systems began with the foreign companies products such as Fondital Group, Global Radiatori, Ferroli, etc. There are now Russian aluminum radiators companies that adhere to European standards, for example ROYAL Thermo, Rifar. The thermal characteristics of radiators are usually specified by the manufacturer. However, they are not always confirmed in practice. This is due to the fact that radiator connecting method is not taken into account. In some technical data sheets, the power reduction factors are given depending on the difference between the average coolant temperature and the air temperature in the room. Therefore, the study of the influence of aluminium heating appliances connecting on its thermal characteristics is an actual task. The article presents the results of research of radiator of the ROYAL Thermo Evolution type, it was made on request from company specialising in heating systems design. It was found that the actual thermal power of one section varies in the range of 135 … 225 W, depending on the connection method of the radiator, the thermal power of the section declared by the manufacturer corresponds only to the diagonal «top-bottom» connection, the thermal power of the eight-section radiator with one-sided «top-bottom» connection is 12% higher than with a diagonal one. Studies show, when designing heating systems, it is necessary to take into account the connection method and the number of device sections.

Abstract A comprehensive study of the efficiency of the 1.5 MW Arimax Bio Energy hot water boiler operating on wood pellets with a high amount of fines has been carried out. Fuel characteristics and its compliance with the quality requirements of Russian and European standards have been investigated. The components of the heat balance and emission of harmful substances have been determined. Thermovision study of the boiler was carried out. The comprehensive study showed that the boiler provides sufficiently high technical and economic performance and minimal emissions of nitrogen oxides and carbon monoxide. However, the high amount of fines in the pellets significantly increases the emissions of particulate matter and especially black carbon into the environment.

The Power engineering is an inseparable part of the contemporary world that has a negative influence on the ecology; in particular it provokes the pollution of atmosphere with such harmful emissions as nitrogen and carbon oxides. Different methods are used to reduce the emission of harmful substances. The efficiency of such methods is increased when these are used in combination and not separately. The recirculation of flue gases and the use of contemporary technologies for municipal boilers, in particular jet-niche technology (JNT) enabled the reduction of NOx and СО emissions to the levels that meet the requirements of European standards simultaneously improving the efficiency of the operation of the fire-engineering facility. The principle of operation of the JNT is based on the formation of the compact stable self-controlled vortex structure and on the interaction system of flammable and oncoming oxidizer flows. This technology enables the operation at minimum recirculation values and it means that all boiler parameters can be retained, in particular starting characteristic, combustion stability and unavailability of vibration modes including a high level of fuel burnout. The obtained research data showed that NОх values were in the range of 80 to 140 mg/m3 when the oxygen content at the furnace inlet was 20% and lower for different boiler systems (DKBR-10, KVGM-6.5, PTVM-50) at CO values close to 50 mg/m2. Hence, the use of the burners of a JNT type enables the reduction of NОхemissions and retains the combustion process efficiency.

The article is devoted to the development of a combined methodology. We are talking about the process of sociolinguistic study of the languages of small peoples. Most of these idiom languages (in Russia they are concentrated mainly in Siberia) are younger and little-studied (in relation to speech and texts). They need extensive documentation on European standards. Documentation and subsequent processing of the collected material are made using modern technical means: computer technologies and programs. We also believe that other methods of research can be applied to them, including traditional sociolinguistic ones. The article justifies the development of a combined methodology for these languages. The essence of this approach is as follows: using methods and techniques from the arsenal of sociolinguistics, it is necessary to fix specific structural characteristics. The combined presentation of the information of sociolinguistic and structural-semantic plans gives a combined description of the desired linguistic formations as idiom languages. Most idioms of Siberia (in particular, the Soyot language, the Koibal dialect of the Khakass language) have scientific descriptions, but they are not enough. In addition, these languages are not described as idioms in them. Understanding the available materials from this angle will help clarify the ways of developing the languages of small peoples in modern times.

There is a general concern about the rationalization of resources and the management of waste. Plant residues can contribute to the development of new non-polluting construction materials. The objective of this study was to valorize a plant residue such as the giant reed and obtain a particleboard with cement using potato starch as a plasticizer in a manufacturing process involving compression and heat. The influence of cement and starch in different proportions and its stability over time were analyzed. Finally, their physical and mechanical properties were evaluated and compared to European Standards. High-quality sustainable particleboards (boards with high structural performance) were obtained and can be classified as P6 according to European Standards. Mechanical properties were improved by increasing the starch content and pressing time, whereas greater resistance to water was obtained by increasing the cement content. Giant reed particles seem to tolerate the alkalinity of the cement since there was no sign of degradation of its fibers. The use of these residues in the manufacture of construction materials offers a very attractive alternative in terms of price, technology and sustainability.

The article analyzes the political process in the Republic of Bulgaria and a number of elections to the National Assembly,which in 2021 were already in April, July and announced for November.The factors, which influenced the need to hold parliamentary elections three times in a row.This shows, that the state is going through a difficult period of instability and turbulence.Building a democratic state governed by the rule of law in Bulgaria,despite its membership in the EU, it is still in its infancy. The author emphasizes that the state is growing alienated from democratic political processes and despair of their effectiveness.This requires legal regulation of the following issues:ensuring universal suffrage;the possibility of campaigning and outreach among voters on others,in addition to the state (Bulgarian) languages,after all, large minorities live in Bulgaria (Turkish, Roma, etc.);improving the financing of election campaigning and the mechanism for appealing the results of parliamentary electionsbased on the transition from indirect to direct appeal by election participants to the NZB of their results. Solving the main problem of Bulgaria – reducing corruption,in fact, it did not happen.Positive success in the fight against corruption can be achieved with the support of the population,his belief that the state will be able to defeat corruption,clear enforcement of anti-corruption measures in various government agencies and institutions.The growth of political consciousness of citizens,which is expressed in a broad protest movement,in the medium term may become the internal basis for the formation of real,rather than a formal electoral system organized according to European standards.
