This paper describes a new 256-bit block symmetric substitution-permutation cipher, called managed substitution cipher. This is a cipher with single-layer permutated transformations in each cycle. The management of substituted transformations occur by including them in a chain so that the output value of the previous SL transform is fed to the input of the current fortified 32-bit substituted transformation (SL conversion) along with the current value of the input data block through the adder for modulo 2. This enables to activate almost all S-blocks of the second cycle and subsequent cycles and eventually improve the dynamic indicators of the arrival of the cipher to the state of random substitution. The results of the evaluation of randomness indicators and the possibility of using random S-blocks are given. It is shown that such construction of cycled function allows us to use random substitutions without any selection in a cipher without reducing its strength.

Рассмотрены состояние и перспективы развития мясного скотоводства в Российской Федерации. Проведен мониторинг численности поголовья, породного состава и продуктивности мясного крупного рогатого скота во всех категориях хозяйств, изучены масштабы и объемы бонитировки скота за 20102018 годы. По данным Минсельхоза России, в 2018 году поголовье крупного рогатого скота в стране составило более 18 млн голов, в том числе численность животных специализированных мясных пород во всех категориях хозяйств достигла 2,26 млн голов. Комплексная оценка 711,16 тыс. голов, или 34,1 от общей численности мясного скота, в том числе 389,8 тыс. коров, принадлежащих к 15 породам и типам, разводимым в 57 регионах Российской Федерации показала, что наибольшее подконтрольное поголовье имеют абердин ангусская порода (417545 гол.), калмыцкая (137262 гол.), герефордская (87278 гол.) и казахская белоголовая породы (52563 гол.). Все подконтрольное поголовье животных является чистопородным и IV поколения, в том числе 99,7 быков-производителей и 99,3 коров. Анализ живой массы пробонитированного поголовья выявил тенденцию к ее повышению у коров всех возрастов в среднем на 54 кг, быков производителей на 39 кг, или на 16,7 и 5,2 за последние 9 лет, соответственно. Живая масса коров по итогам 2018 года в среднем составила 546 кг, быков-производителей 791 кг. По состоянию на 1.01.2019 года, племенная база мясного скотоводства страны представлена 270 племенными стадами, в том числе 46 племенными заводами и 224 племенными репродукторами. В 2018 году в различные категории хозяйств из племенных предприятий было продано 35517 голов племенного молодняка, в том числе 6388 ремонтных бычка с классами элита и элита-рекорд (85,3). В 2018 году было продано племенного молодняка в расчете на 100 коров галловейской породы 33,0 головы, казахской белоголовой 29,1 герефордской 28,0 калмыцкой 22,2 лимузинской 15,5 абердин ангусской 8,8 русской комолой 8,2 и симментальской мясной 4,7 голов. На основании мониторинга состояния мясного скотоводства страны за 20102018 годы были намечены перспективы дальнейшего развития.The article considers the state and prospects of development of beef cattle breeding in the Russian Federation. The number of livestock, breed composition and productivity of beef cattle in all categories of farms was monitored, the scale and volumes of bonding of cattle for the studied 9-year period (20102018) were studied. According to the Ministry of Agriculture of Russia, in 2018 the number of cattle in the country amounted to more than 18 million heads, including the number of cattle of specialized meat breeds in all categories of farms reached 2.26 million heads. A comprehensive assessment of the number of livestock in the amount of 711.16 thousand animals or 34.1 of the total number of beef cattle, including: cows 389.8 thousand heads belonging to 15 breeds and types bred in 57 regions of the Russian Federation, showed that the largest controlled livestock are: Aberdeen Angus breed 417545 animals, Kalmyk 1372726 animals, Hereford 87278 animals and Kazakh white-headed breed 52563 animals. Almost all of the controlled livestock of animals is purebred and IV generation, including: respectively 99.7 of bulls producers and 99.3 of cows. The analysis of live mass of a livestock revealed a tendency to its increase at cows of all age on average on 54 kg, bulls on 39 kgor for 16.7 and 5.2 for the last 9 years respectively. The live mass of cows following the results of 2018 averaged 546 kg, bulls 791 kg. As of January 1, 2019, the breeding base of beef cattle breeding in the country is represented by 270 breeding herds, including: 46 breeding plants and 224 breeding reproducers. In 2018, 35,517 heads of pedigree young animals were sold to various categories of farms from pedigree enterprises, including 6,388 repair bulls with elite classes and an elite record record for appraisal (85.3). An analysis of the sales volume of pedigree young animals in the context of farmed meat breeds showed that in 2018 pedigree young animals per 100 cows were sold in the country: Galloveian breed 33.0 goals, Kazakh white-headed 29.1 goals, Hereford 28, 0 goals., Kalmyk 22.2 goals., Limousin 15.5 goals., Aberdeen Angus 8.8 goals, Russian kolola 8.2 and Simmental meat 4.7 goals. Based on the monitoring of the state of beef cattle breeding in the country for the study period (20102018), prospects for further development were outlined.

The article deals with the causes of the negative situation in the banking sector, as the state of the bank depends on the analysis of almost all aspects of banking activity for some time. It is determined that during the banking sector audits, the state regulator uses analytical data on the banking sector's operations with its monetary obligations, compliance with maturities and maturities of assets that operate and terms and amounts of liabilities, namely, dealing with banking sector liquidity. As their financial reliability is important in the banking sector, therefore, bank clients are a socio-economic sector, needing an objective and independent assessment, as reliability directly affects the socio-economic development of the country. The banking sector was analyzed in 2016-2019 and it was found that during this period violations of laws and regulations issued by the state regulator were made in the banking sector. A number of penalties, written warnings and administrative penalties were applied by the state regulator. The method of determining the rating of banks in respect of which penalties were applied by the state regulator is proposed. The rating allows investors and potential clients to understand the situation in the banking market and helps banks identify their weaknesses and correct their work. The application of the proposed economic and mathematical model in the rating of participants in the banking sector can have a positive effect on: improving the quality of management in the banking sector and transparency in the activities of each individual bank; standardization of technologies of rating of the banking sector under the prism of the applied sanctions by the state regulator. Therefore, there is a need for an in-depth study of the techniques used by credit rating agencies in the banking sector and the identification of the main problems in establishing the rating of the banking sector. Key words: banking sector, state regulator, economic sector, efficiency, rating, rating, social sector.

Existing Data

While colonization as policy is formally a historic phenomenon in Norway and elsewhere, many former structures of state organization – including their relationship to sport – remain under post-colonial conditions. This paper is concerned with how the Norwegian government contributes to creating a situation, which includes the Norwegian sports confederation (NIF) but excludes the indigenous people Sámi’s sports organisation. Based on existing data and literature, we analyse how the state favours NIF through a chain of legitimating acts. Thus, sport is a preserve of colonization, where a one-sided legitimation parallels a de-legitimation of the overarching sport policy goal of sport-for-all. However, there are signs of change whereby actors are challenging NIF’s monopoly and ‘older’ state-sport regimes.

Modern Era

In this modern era, the activities of almost all humans depend on machines they make, such as single-phase induction electric motors, which are used to chop plastic waste. This chopping machine aims to help plastic collectors process plastic waste into small pieces, making it easier to pack and ship plastic out of the area for reprocessing. The plastic waste shredding machine is made using a crushing system with a fan-shaped blade construction consisting of 39 blades divided by two rotating rows opposite the cover box using a chain motor gear transmission element. Most of the chopper machines on the market use engines with diesel or diesel fuel, therefore a chopper machine using an electric motor is designed to compare the motor power without the addition of capacitors and capacitors. The waste load used for motors without additional capacitors, medium and large bottles measuring 375 ml to 1500 ml, the machine can chop as much as 800 grams with the highest measurement of power 578.0 Watt, current 4.192 A, the lowest motor speed measurement is 1414 rpm and the reducer speed is 22.9 rpm . The waste load used for motors with additional capacitors, medium and large bottles measuring 375 ml to 1500 ml, the machine can chop 1000 grams with the highest measurement of power 732.7 Watt, current 4.149 A, the lowest motor speed measurement is 1464 rpm and the reducer speed is 22.9 rpm.

The repair industry in almost all countries has entered a critical period, characterized by the need to combine and use various strategies and technologies for maintenance and repair of new equipment, as well as equipment produced many years ago. (Research purpose) The research purpose is in analyzing the state of the repair and maintenance base of the agro-industrial complex and justifying the possibilities of its modernization using intelligent technologies. (Materials and methods) Authors used methods of generalizing data from various services of agro- industrial formations of individual regions, materials of scientific and technical literature and research developments, studied data on the practical use of modern resource-saving technologies by engineering services of the agro-industrial complex of the regions when carrying out repairs and service and technological services. (Results and discussion) The lack of information about the state of the repair and maintenance base makes it difficult to determine all the criteria associated with the transition of manufacturers to a contract of the entire life cycle. Obtaining information about the state of the repair and maintenance base of the agro-industrial complex is a very important stage that contributes to the modernization of this base and attracting not only the governments, but also agricultural machinery manufacturers to modernization. (Conclusions) The technological level of the enterprises of the repair and maintenance base of agriculture has significantly decreased in recent years, and this has affected the decline in technical readiness indicators, which confirms the need to conduct research and implement in practice the main measures related to the modernization of the specified repair and maintenance base.

Key Points In almost all U.S. states, pregnancies reported as occurring at the right time or being wanted sooner than they occurred comprised the largest share of pregnancies in 2017, though proportions varied widely by state. The proportion of pregnancies that were wanted later or unwanted was higher in the South and Northeast than in other regions, and the proportion of pregnancies that occurred at the right time or were wanted sooner was higher in the West and Midwest. From 2012 to 2017, the wanted-later-or-unwanted pregnancy rate fell in the majority of states. However, no clear pattern emerged for any changes in the rate of pregnancies that were reported as wanted then or sooner or in the rate of those for which individuals expressed uncertainty.

Blast Furnace Hearth

The state of a blast furnace hearth, especially the liquid level of hot metal and slag during the tapping process, is of crucial importance with respect to a long campaign blast furnace. In practice, the state of the hearth is evaluated mainly by the experience of operators. In this paper, the electromotive force (EMF) is used to monitor the liquid level of a laboratory scale of blast furnace hearth and the effect of liquid level, EMF sensors position and the thickness of refractory on EMF signals are tested using a single layer of water and double layers of water and oil. After laboratory experiments, the electromotive force (EMF) is used to monitor the liquid level of torpedo ladle successfully. Laboratory experimental results show that the change in liquid level can be characterized by EMF signal. The state of liquid surface and local thermal state cause the EMF signal to vary in the circumferential direction of the vessel. Furthermore, the EMF signal magnitude decreases with the decrease of the thickness of the graphite crucible. Finally, the main conclusions of the laboratory experiment are supported by the torpedo ladle experiment.
