Pressure fire hoses are one of the main types of fire-fighting equipment, on the serviceable condition of which depends the operational activities of fire and rescue units and successful firefighting. At present, Ukraine has entered into force with (01.08.2021) the national standard, which contains modern European requirements for assessing the quality of flat-hose fire hoses for fire and rescue vehicles. This standard was developed by the Institute of Public Administration and Research in Civil Defense in the framework of research work "Fire hoses – test methods" and adopted by order of SE "UkrNDNC" from 23.03.2021 № 107. In order to assist in solving this problem, the Institute of Public Administration and Research in Civil Defense put into operation, tested and verified the installation for testing fire pressure hoses, which will check the quality of pressure flat hose for fire and rescue vehicles in accordance with modern European requirements. The installation is intended for tests of pressure fire hoses carried out on the following quality indicators: working, test and burst pressure; abrasion resistance; resistance to hot objects; resistance to open flame. The unit is operated at air temperature from 10 ° С to 25 ° С and relative humidity from 15% to 90%. The installation is a metal table, which consists of two levels (upper and lower). The main part of the tests is to be performed at the upper level with the help of three removable modules. The lower level provides one stationary module on which tests for working, test and burst pressure are carried out. The upper level of the installation is designed to test pressure fire hoses for the following quality indicators: resistance to surface abrasion, resistance to point abrasion, resistance to hot objects and resistance to open flames. For versatility and convenience of work on installation on the top level of a table the possibility of change of modules depending on their need is provided. The lower level of the installation is intended for carrying out tests of pressure fire hoses on quality indicators – working and test pressure, bursting pressure. At the lower level of the metal table is a rectangular metal box, which has a closing lid. During the tests, the sample of the test sleeve is automatically filled with water, which drains after the test. To fix the samples of fire hoses of different diameters (25, 32, 38, 51, 66, 77, 100, 125 and 150) mm, the installation includes special cones and plates.

European Standards

The urgency of the necessity of experimental substantiation of quality indicators of the fire-fighting layflat hoses for fire – rescue equipment and methods of their estimation is noted, taking into account the modern approaches set out in European standards. The results of experimental researches of fire-fighting layflat hoses for fire – rescue equipment by quality indicators are presented: resistance of the hoses to the action of working hydraulic pressure, resistance of the hoses to the action of the proof hydraulic pressure, burst pressure and abrasion resistance. Delivery fire hoses are one of the main types of fire fighting equipment. Delivery fire hoses in the course of operation undergo mechanical wear, are exposed to the sun's rays, microbiological putrefactive processes, accidental ingress of chemically active substances, the influence of low and high temperatures, irreversible processes of material aging. All this causes the appearance of defects of different nature. Analysis of the causes of failure of delivery fire hoses showed that of all failures more than 60% are fistulas, as well as breaks and disruptions of heads - 30% and 10% respectively. The analysis of the presence and nature of defects during the regular testing of workers and decommissioned fire hoses showed that the defects are divided into: explicit (gusts and fistulas) that violate the tightness of the hoses; visible cuts, abrasions, missing and chemical corrosion from contamination of fuel and lubricants that do not violate the tightness of the hoses; hidden (unnoticed cuts, breaks in the threads of the power frame, etc.) that do not violate the tightness of the hoses. Studies have shown that only 75% of defects are detected during hydraulic testing, and undetected defects result in hoses failing in a fire. To date, requirements for assessing the quality of delivery fire hoses for fire - fighting equipment in Ukraine are set out in the standard DSTU 3810-98. At the same time, these requirements are to some extent obsolete and do not meet the current regulations of the leading countries in the world on this issue. In view of the above, it is urgent to experimentally justify the quality indicators of the fire-fighting layflat hoses for fire – rescue equipment and methods of their evaluation, taking into account the modern approaches set out in European standards. The results of the pilot studies will be used to justify the provisions of the draft national standard of Ukraine that will be developed and to improve the existing test base.

Flooded Areas

The danger to society caused by the consequences of natural disasters tends to increase despite the general technical progress and the application of measures to prevent them and combat them. Every year the number of victims, in particular, from floods increases by an average of 6%. Flooding in certain areas can occur due to floods and inundations. Floods are natural processes that occur in the biosphere and affect the planet for millennia. Flood is a significant flooding of the area due to rising water levels in rivers, lakes, reservoirs, caused by downpours, spring snowmelt, wind surges, destruction of dams, dams and more. Floods cause great material damage and casualties. The water level in reservoirs depends on many different factors. All over the world, experts conduct long-term observations, tracking all seasonal changes, and collect data for forecasting. Floods and their causes are well studied. The main causes of these disasters are: - prolonged rains; - melting snow; - raising the bottom; - strong winds and storms; - groundwater; Thus, the issue of using modern technical means of protection against flooding of territories and objects of various purposes is relevant. A number of publications consider current trends in effective flood risk management planning in the European Union and describe the catastrophic consequences of floods and ways to combat them, and so on. At the same time, these studies do not contain data on testing and implementation in Ukraine of modern technical means to combat floods in the EU. To address these issues, the Institute of Public Administration and Research on Civil Defense commissioned by the State Service of Ukraine for Emergencies has developed a method of testing water-absorbing devices designed for: - flood protection; - changes in the direction of water flow during floods, torrential rains, melting snow, etc. - removal of water from flooded areas (basements, garages, etc.); - elimination of environmental accidents (spills of oil, diesel fuel and other chemicals). Developed by the Institute of Public Administration and Research on Civil Protection, the method of testing water-absorbing means will allow in the future to test and assess the suitability of such technical means for use by fire and rescue units when performing tasks to remove water from flooded areas and create barriers to water. time of protection against floods, changes in the direction of water flow during floods, torrential rains, melting snow, etc.

The purpose of the article is to determine performance indicators for the digital transformation of public administration in Russia, to implement the benefits of the program, achieve its goals and improve the quality of public administration in our country. The study identified factors and criteria for the quality of digitalization of public administration at the international and regional levels. Using correlation analysis, it was determined that the current performance indicators of the "Information state" program are only indirectly related to improving the quality of public administration. That is why despite quite significant progress digitalization, the quality of public administration remains low. On the contrary, surveys about public services were positively interconnected with governance quality indicators. It was also proved that indicators and indexes of digitalization of public administration have a positive impact on governance quality indicators. Based on the results of the analysis, it was proposed to include the above-mentioned factors as performance indicators for the new program "Digital public administration", along with performance indicators of the program itself for quality control of its implementation.

The criteria of the coordinate measurements quality at pilot-experimental production based on contemporary methods of quality management system and traditional methods of the measurements quality in Metrology are considered. As an additional criterion for quality of measurements, their duration is proposed. Analyzing the problem of assessing the quality of measurements, the authors pay particular attention to the role of technological heredity in the analysis of the sources of uncertainty of coordinate measurements, including not only the process of manufacturing the part, but all stages of the development of design and technological documentation. Along with such criteria as the degree of confidence in the results of measurements; the accuracy, convergence, reproducibility and speed of the results must take into account the correctness of technical specification, and such characteristics of the shape of the geometric elements to be controlled, such as flatness, roundness, cylindrical. It is noted that one of the main methods to reduce the uncertainty of coordinate measurements is to reduce the uncertainty in the initial data and measurement conditions, as well as to increase the stability of the tasks due to the reasonable choice of the basic geometric elements (measuring bases) of the part. A prerequisite for obtaining reliable quality indicators is a quantitative assessment of the conditions and organization of the measurement process. To plan and normalize the time of measurements, the authors propose to use analytical formulas, on the basis of which it is possible to perform quantitative analysis and optimization of quality indicators, including the speed of measurements.

Rules Of The Game

Law and public administration schools in Russia vastly exceed in their popularity sciences and engineering. We relate such lopsided demand for higher education to the quality of institutions setting “rules of the game” in economy and society. Cross-country and Russian interregional data indicate the quality of institutions (rule of law, protection of property rights etc.) is negatively associated with the demand for education in law, and positively — in sciences and engineering. More gifted younger people are particularly sensitive to the quality of institutions in choosing their fields of study, and such selection is an important transmission channel between institutions and economic growth.
