The object of this study is the detection of fires in the premises. The problem that was solved is the development of tools to assess the reliability of detection of fires in the premises based on the recurrence of the vector of increases in dangerous parameters of the gas environment. The method includes the sequential implementation of five procedures related to the formation of the vector of current increases in dangerous parameters, determining the recurrence of the current vector and evaluating the empirical distribution function relative to the calculated current recurrence of the state vector. Features and distinctive attributes of the developed method are the use of empirical cumulative distribution function in relation to the current recurrence of the state of hazardous parameters of the gas environment in the premises during fires. This makes it possible to solve the task of developing tools for the numerical determining of the trust limit for the predefined level of significance (reliability) and the likelihood of detecting fires in the premises in real time. The scope and conditions for the practical use of the obtained results are the modern and promising means and fire protection systems of various types of premises in buildings and structures. The proposed method was tested on the example of igniting test materials in the laboratory chamber. It is established that for materials with a high combustion rate (alcohol and cellulose) with a probability of 0.95, there is a sharp decrease in the value of the empirical function assessment to zero values. For timber, the value of this estimate is 0.15, and for textiles, the minimum value of the estimate is 0.31. It is established that the boundaries of the confidence interval with the level of significance covering the obtained estimates are determined by the value of ±0.086. In general, the results of the test indicate the operability of the proposed method for determining the reliability of detection of fires in the premises on the basis of the current degree of recurrence of increases in dangerous parameters of the gas environment

This paper reports the analysis of compositions for fire protection of wood that established that there are not enough data to explain and describe the process of fire protection and, accordingly, the fire-hazardous properties of wood, in order to protect people. The development and research of a set of properties of fire-resistant materials leads to the design of new types of such materials. The object of this study was a fire-protective two-component intumescent varnish for wood. The essence of the research is to determine the indicators of fire danger of wood, fire-protected by coatings, and the impact exerted on them by the formed heat-insulating layer of coke, making it possible to justify the effectiveness of the fire-retardant coating under the influence of temperature. The volume of fire-retardant and hydrophobic coating has been optimized, which ensures the lowest value of loss of mass by fire-protected wood during thermal action. Its lowest value was determined when using flame retardant in the volume of 589 g/m2 and a hydrophobic agent in the volume of 54 g/m2. When determining the combustibility of fire-resistant wood, it was established that the temperature of flue gases during tests was no more than 103 °C, the length of damage to the sample did not exceed 143 mm. At the same time, the weight loss did not exceed 19 g, and the independent burning of wood did not exceed 23 s. In addition, the wood withstood the surface effect of a heat flow of 35 kW/m2, while surface combustion did not occur, and the value of the coefficient of smoke formation was 432 m2/kg during the smoldering of the fire-proof sample. Unlike wood protection with fire-retardant swelling paint, the fireproof wood with two-component varnish, does not change color and refers to low combustibility materials; it is hard to ignite, dose not spread the flame by surface, with moderate smoke-forming ability. The practical significance is the fact that a certificate of conformity was issued based on the reported results. Thus, there are grounds to assert the possibility of directed adjustment of wood fire protection processes by using coatings that can form a protective layer on the surface of the material

Published: July 2022

A given model of yield forecasting using an artificial neural network connects the wheat crop with the amount of productive moisture in the soil, soil fertility, weather, and factors in the presence of pests, diseases, and weeds. The difficulty of creating a yield forecast system is in the correct choice of predictors that have the greatest impact on yield.
To build the model, moisture in the 100 cm layer of the soil, the content of nitrogen, phosphorus, humus, and soil acidity in the soil were used as input parameters. The amount of precipitation over 4 months, the average air temperature for the same period, as well as the presence of diseases, pests, and weeds were also taken into consideration. Data on 13 districts of the North Kazakhstan region in the period from 2008 to 2017 were used. The output parameter was the yield of spring wheat over the same time period.
The relative importance of input variables in relation to the output variable was used to determine the weight values of input variables.
An artificial neural network of error backpropagation was used as a method. The advantage of this method is that the quality of the forecast increases with a large amount of training data, as well as the ability to model nonlinear relationships between different data sources.
After training the artificial neural network and obtaining predictive data, good results were achieved for predicting wheat yields (p=0.52, mean absolute error in percentage (MAPE)=12.02 %, root mean square error (RMSE)=3.368).
Thus, it is assumed that the developed model for forecasting wheat yields based on data can be easily adapted for other crops and places and will allow the adoption of the right strategies to ensure food security

UAVs or drones as an alternative solution to providing high-quality Internet service in difficult terrain are environmentally friendly and do not consume electricity during the day as is the case with communication towers. But the developers of the network face difficulties in the drone communication system associated with the need to take into consideration unpredictable weather conditions and terrain, as well as the short life of the drone's batteries. Therefore, the object of this study is the process of managing UAV traffic through the use of gNB-IoT in 5G.
The possibility of using a mobile UAV repeater during traffic management using radio resources (RR), radio access network (RAN), the infrastructure with broadcasting tools and dynamic connection using MU-MIMO modulation is shown. The use of these tools makes it possible to connect the drone to the wired base network from the provider and then restore the radio frequency signal and broadcast to another coverage area where this subscriber does not have network coverage, use the channel quality indicator (CQI) representation as a QoE function.
Undoubtedly, traffic management is the process of obtaining information about traffic control from one endpoint to another, which confirms the reliability and management of data transmission. Meanwhile, drone traffic management can be used to reduce time delays and remove network interference by relying on Internet of Things programs that use NB-5G technology. The UAV's traffic management improvement process uses a proposed algorithm to generate dynamic flow data management to enhance traffic processing of flow control in the IoT

One of the key goals of digital transformation in Europe is to transfer 100 % of public services online, in particular, by 2030, all key public services should be online.
This process requires the creation of comprehensive services that combine several services provided to the user on one application. The introduction of comprehensive services significantly unloads work of the bodies providing services and significantly simplifies the process of obtaining the results of services for users. Thus, the introduction of comprehensive services significantly improves the process of providing public services for all participants in the process.
The formation of complex services is carried out solely on the principle of combining according to a life (business) event or situation.
However, as practical experience shows, users often apply for several services at the same time, and these services are not connected by one life event. This can be seen by analyzing statistics on the provision of services by service centers.
The use of statistical analysis methods makes it possible to identify a hidden relationship between services. Based on this, a new principle of combining services is formulated. The object of this research is the process of forming a portfolio of services based on this principle.
An algorithm for forming a portfolio and providing recommendations for a decision maker has been developed. Recommendations are represented in the form of sets of services that can be included in the portfolio. The application of this principle will expand the range of comprehensive services at the expense of new portfolios. This will simplify and improve the process of providing services for both authorities and users.
An example of creating a portfolio of services is considered and recommendations for the application of the proposed methodology are given. Dataset of 84 services was analyzed, it was recommended to create 2 portfolios

Published: July 2022

Context. UHF transmission systems make extensive use of transmission line segments, the characteristics of which have a significant impact on the performance of various information technologies. One of the problems of production of transmission lines is to obtain a given wave impedance, which significantly affects the electrical and information characteristics of the entire set of equipment. Currently, there is a burning issue of estimating the influence of disturbing factors on various electrical characteristics of long line segments. To date, the most fully developed methods for assessing the effect of disturbing factors on the wave impedance of a homogeneous line (the wave impedance is constant) under regular perturbations. In this case, the influence of perturbations on the reflection coefficient of matched lines was mainly considered. The effect of perturbations on the other characteristics of homogeneous and, especially, inhomogeneous lines has not been sufficiently studie

Objective. The purpose of this paper is to determine the effect of wave impedance perturbations on the transmission line impedance matrix. Knowing the perturbed impedance matrix, it is possible to determine the distortion of the characteristics of any device built on transmission line segments.

Method. The paper uses the method of perturbation theory of linear differential operators applied to equations describing processes in inhomogeneous long lines.

Results. The obtained results make it possible to estimate the influence of regular and irregular perturbations of the wave resistance (wave conductance) on the transmission line matrix considered as a quadrupole. Such matrix can be any quadrupole matrix: resistance matrix, conductance matrix, circuit matrix. This makes it possible, according to the desired function of the circuit (gain, input impedance, reflection coefficient), to determine the allowable deviation of the wave impedance from the nominal value in order to select a tolerance for reproducing the wave impedance.

Conclusions. The proposed criterion for estimating line parameter deviations using the norm of the four-pole matrix is inherently an integral criterion and can be used to preliminarily estimate the frequency domain of the strongest distortions, regardless of the functional purpose of the transmission line segment. The developed approach is applicable to both homogeneous and heterogeneous transmission lines and covers both regular and irregular wave impedance perturbations.

Objective is to synthesize neural network diagnostic models of aircraft parts after operational processes with a high level of accuracy.
Method. It is proposed to research the use of two approaches to the synthesis of neural network diagnostic models. So, using a system of indicators, the topology of the neural network is calculated, which will be trained using the method of Backpropagation method in the future. The second approach is based on the use of a neuroevolutionary approach, which allows for a complete synthesis of the neural network, dynamically modifying the topology of the solution in addition to the parameters. the final decisions are compared in the accuracy of work on the training and test data set. This approach will allow to determine the possibility and correctness of using neuroevolutionary methods for the synthesis of diagnostic models.
Results. Neuromodels for diagnostics of aircraft parts based on the results of operational processes have been obtained. The obtained results of comparing the methods used for synthesis made it possible to form recommendations for the implementation of neuroevolutionary methods in the synthesis of diagnostic neuromodels.
Conclusions. The results obtained during the experiments confirmed the operability of the mathematical software used and allowed us to form recommendations for further use of the considered methods in practice in order to synthesize diagnostic neuromodels. The prospects for further research may consist in expanding the input data sets in order to synthesize and study more complex topologies of neural network models.

A crise fiscal da União: o que aconteceu recentemente?
Authors: GIAMBIAGI FABIO
Published: July 2022

RESUMO Este artigo atualiza a discussão sobre a situação fiscal do governo central no Brasil. Mostra-se que, entre 1988 e 1995, as receitas do Tesouro Nacional aumentaram quase 3% do PIB. Consequentemente, durante 1990-1995, o governo central apresentou equilíbrio fiscal, resultado melhor do que o déficit médio de 2,8% do PIB observado em 1985-1989. Apesar desses números, destacam-se alguns problemas da situação atual das contas fiscais e do peso crescente da massa salarial e dos gastos da Previdência Social (a) que juntas saltaram de 47% para 60% do faturamento entre 1988 e 1995, (b) é apontada como a razão mais importante para a restrição orçamentária da maioria dos ministérios.

ABSTRACT: Methyl jasmonate (MeJA) is recognized as a plant hormone that induces several biochemical changes related to improving fruit quality, but it is evident that the effect of MeJA during postharvest is very variable upon concentration, plant species, and even cultivars. The objective of this research was to relate the application of this regulator at low concentration (10 µmol L-1 for 24 h) to changes in postharvest physiology, on the incidence of anthracnose and quality of ‘Golden’ papaya fruit during storage at 24 ± 1°C. From the seventh day of storage, anthracnose incidence was reduced by more than 50% with MeJA treatment. The lesion area after infection was also reduced. Although, MeJA reduced fruit acidity, the ascorbic acid and soluble solids content were not altered during storage with the hormonal treatment. The skin color and pulp firmness showed slight retention. The reduction in ethylene production was accompanied by a reduction of respiration in treated fruits. MeJa increased CAT activity only in the skin whereas SOD activity was not induced by MeJA in both skin and pulp. Although, the increase of CAT from the third day of storage may have contributed to the reduction of lipid peroxidation in the skin, the MDA reduction in the pulp cannot be explained only by CAT activity. In summary, the application of MeJA in ‘Golden’ papaya reduced the incidence and severity of anthracnose, decreased respiration, ethylene production and lipid peroxidation. It is concluded that the application of MeJA at a low concentration (10 µmol L-1) may contribute to anthracnose control in ´Golden`papaya and slows the ripening of fruits.

Published: July 2022

RESUMO A indústria de fertilizantes no Brasil vem crescendo de forma acelerada puxada pelo aumento do agronegócio, porém essa cadeia industrial envolve operação contínua em meio agressivo, gerando paradas para manutenção corretiva devido ao desgaste da cadeia industrial por corrosão. Nos últimos anos, o custo da indústria com manutenção chegou a 4% em relação ao faturamento bruto. Com o objetivo de diminuir esse custo e visando à sustentabilidade, têm-se investido em novas técnicas para proteger a planta de produção contra os efeitos severos da corrosão, objetivando o aumento da produção, diminuição das paradas para manutenção, prorrogação da vida útil da planta e diminuição de resíduos tóxicos. Vários estudos com extratos de origem animal e vegetal têm sido realizados como possíveis aditivos de proteção à corrosão de superfícies metálicas, por serem considerados ambientalmente corretos, formando um filme na interface metal-meio corrosivo. Esse trabalho mostra estudos de corrosão por técnicas eletroquímicas em aço 1020 contendo extratos de Struthio Camelus (avestruz), Crolatus Durissus (cobra cascavel) e de Elaeis Guineensis (palma) em solução de Cloreto de Sódio (NaCl) e Ureia 3%. Os resultados indicaram uma diminuição significativa nas taxas de corrosão do aço quando submetido a Ureia 3% na presença de todos os extratos, quando comparado com os resultados obtidos na presença de NaCl 3%. O aço carbono com extrato de Crolatus Durissus em Ureia 3% apresentou taxa de corrosão de 0,003 mm/ano, o melhor comportamento nesse meio, seguido do extrato de Elaeis Guineensis, 0,009 mm/ano. O aço na presença de Elaeis Guineensis com NaCl 3% apresentou uma taxa de corrosão de 0,05 mm/ano, sendo o melhor resultado para esse meio corrosivo.

Fiscal Policy and regional inequality in Brazil
Authors: Cardoso Débora Freire , Souza Kênia Barreiro de , Ribeiro Luiz Carlos Santana , Cardoso Guilherme Silva
Published: July 2022

Abstract This paper aims to estimate the long-term impacts of an austerity policy in the Brazilian regions. Our main contribution is to measure those effects using a dynamic interregional general equilibrium model, capturing the indirect impacts in sectors and regions, in addition to the direct effects of the expenditure cuts. The main results show that the fiscal adjustment would attenuate growth in most of the Brazilian states by 2037. Municipalities located in the poorest regions would be relatively more affected. Furthermore, the adjustment would have a negative impact on regional inequalities in all scenarios, both at the state and municipal levels.
Impact of Merger Announcements on the Stock Returns of Brazilian Acquiring Firms
Authors: Avelino Ricardo Rezende Gomes
Published: July 2022

Abstract This paper assesses the impact of merger announcements on the market value of Brazilian acquiring firms based on 31 transactions that took place from 2004 to 2019 and in which the market value of the target was at least 10% of the market value of the acquirer. The estimates from the BEKK model, which extends the market model to incorporate time-varying betas and volatility clustering, suggest that abnormal returns to acquirers’ stockholders over a 15-day window around the merger announcement are statistically and economically significant, amounting to 5.3584%. Financial and accounting indicators of acquirers prior to and after the merger do not rule out the possibility that these short-run returns reflect misassessment of market participants of the value created by mergers.
Conflito distributivo, inflação inercial e pactos sociais: revisitando os trabalhos de Persio Arida, Edmar Bacha e André Lara-Resende
Authors: Herzog Lucas Bertola
Published: July 2022

Resumo No contexto antecedente ao Plano Cruzado, as formulações teóricas de Persio Arida, André Lara-Resende e Edmar Bacha ganharam destaque por tratarem do fenômeno inflacionário sob a ótica do conflito distributivo entre trabalhadores e empresários. Conforme esses primeiros esforços passaram a dar ensejo a propostas de políticas de estabilização, costuma-se apontar para uma diminuição de importância do elemento distributivo nos trabalhos dos autores citados, indicando uma convergência teórica em direção ao paradigma novo-keynesiano. Embora o conflito distributivo deixe de ser mencionado explicitamente como causa da inflação brasileira - sobretudo após o fracasso do Cruzado - ele segue mobilizado nos esforços dos autores em pensar planos de estabilização. Mais do que uma evolução conceitual, haveria uma mudança na avaliação sobre as possibilidades de gestão dos conflitos distributivos através de pactos sociais e reformas monetárias, podendo se recorrer a políticas de demanda para moderar as ambições de renda dos diversos grupos sociais.

Abstract: The aim of this work was to evaluate the impact of soybean sowing in soil with low water availability, under two management systems, using seeds with and without chemical treatment, on the physiological quality of seeds and seedling emergence. For this, two experiments were set up, one under no-tillage system (NTS) and the other under conventional tillage system (CTS), in a randomized block design, both in a 2x6 factorial scheme, with two seed treatment conditions (with and without) and six periods of seed permanence in the soil (0, 24, 48, 72, 96 and 120 h), with four replications. Germination, vigor, percentage of abnormal seedlings and percentage of dead seeds were evaluated. Seed treatment made it possible to maintain germination at acceptable levels for up to five days of permanence of the seeds in the soil, even in CTS. Sowing in soils with low water availability can lead to reductions of 0.2 and 0.5 percentage points per hour of exposure to dry soil in germination and vigor of soybean seeds, respectively.

Abstract: Soybean seeds may show different responses to weathering deterioration depending on the intrinsic characteristics of the genetic material and the intensity and duration of the rainfall period. This study aimed to evaluate the effect of pre-harvest weathering deterioration on the quality and chemical composition of soybean seeds with different lignin contents in the pod and seed coat. The percentage of weathering damage was evaluated by the tetrazolium test, X-ray test, lignin content in the pod and seed coat, germination, accelerated aging, seedling emergence, seed health test, and oil, protein, and chlorophyll contents. The experimental design was completely randomized in a 7×3 factorial scheme, that is, seven cultivars and three rainfall volumes (0, 54, and 162 mm), simulated when 95% of the pods had a mature color. The physiological and sanitary quality of soybean seeds reduces with an increase in pre-harvest rainfall. Soybean seeds from cultivars with higher lignin contents in the pod present a higher tolerance to pre-harvest weathering deterioration and provide seeds of better physiological quality. Seed oil and protein content is reduced in some cultivars as rainfall increases. Plants with higher lignin contents in the pods produce seeds with a lower incidence of the fungus Cercospora kikuchii and lower chlorophyll content when associated with pre-harvest rainfall.

Abstract: Productive soybean genotypes is one of the main objectives of soybean breeding programs. However, there are few studies on the selection of characteristics associated with the quality and performance of soybean seeds. The objective in this study was to predict physiological and genetic parameters associated with seed quality in segregating soybean populations derived from parents of differing maturity groups. Eight genotypes of the F2:3 segregating soybean population (numbered 163, 24, 57, 108, 164, 169, 157, and 81) cultivated in the 2018/19 harvest were evaluated. To conduct the experiment, a completely randomized design was used. The physiological quality of the seeds was evaluated by germination test, tetrazolium test, and image analysis. Statistical analyses were performed by using a mixed model approach. Greater seed vigor was observed in the genotypes 108, 164, and 169, whose results were among the best for most of the analyzed parameters. The greater mechanical damage and damage due to stink bugs can explain the lower vigor of some seeds, as observed in genotypes 57 and 163, while weathering damage did not correspond to the results of the seed vigor tests. The analyses indicated a greater influence of genetic characteristics than of relative maturity group on the responses of the genotypes. No effect of relative maturity group on soybean seed vigor was evident.

Abstract Knowledge about the nutritional aspects of calla lily, an important species for the floriculture industry, is essential for quality on cultivation. As there are variations in the symptoms of nutritional deficiencies among species, it is necessary to study the development of plants and their nutritional status when grown under nutrient omission. Thus, the aim was to evaluate the development of calla lily plants and identify the levels of nutrients and their interactions in cultivation conditions under nutritional deficiency. The treatments consisted in the use of the complete nutrition solution and the omission of N, P, K, Ca, Mg, S, Fe, B, and Mn, separately. The experimental design was in randomized block design with four replications. The omissions of P, S, Ca, K, N, and B have influenced the plant development providing lower production of leaves and in small size, reduction on shoots production and less leaves emitted by the shoots, besides a lower values of dry matter. Among these nutrients, the deficiencies that most affected the growth and quality of calla lily plants development were N, B and Ca. The B and N deficiency inhibited the flowering and the absence of S and K provided inflorescences production with lower quality, besides malformation. The main interactions that occurred were increasing in the content of K (leaves), Fe (leaves) and Mn (leaves and inflorescences) in the absence of Ca. In the absence of Mg there was an increase in Ca (leaves, rhizomes, and inflorescences), Zn (leaves and roots) and Fe (rhizomes). It can be concluded that the nutritional deficiencies that most affected the production of inflorescences in calla lily were those of B, N, P, K, Ca, and S and the main nutritional interactions occurred in the absence of Ca with an increase in K, Fe and Mn and an increase in Ca, Fe and Zn in the absence of Mg.

Abstract The use of agricultural residues as a substrate is a promising option for orchid acclimatization, which is a critical stage of micropropagation. Thus, this study aimed to evaluate the use of grape residue S-10 Beifort®, isolated or mixed with other agricultural residues, in the acclimatization of Oncidium baueri Lindl. Five treatments were studied (S-10 Beifort®; S-10 Beifort® + carbonized rice husk (CRH); S-10 Beifort® + coconut fiber (CF); S-10 Beifort® + CRH + CF; CRH + CF), with four replications containing 10 seedlings each. After 120 days, the highest survival rate occurred with the mixture CRH + CF (62.5%). The mixture of S-10 Beifort® with CRH provided a greater shoot length (3.7 cm), not differing from the mixture of the three substrates (2.9 cm). S-10 Beifort® + CRH and the mixture of the three substrates ensured greater root length (3.8 cm). The mixture of the three residues provided the highest average of fresh and dry mass accumulation. The pH variation between the substrates was from 5.2 to 6.3, while S-10 Beifort® presented the highest electrical conductivity (2030 μS cm-1) and the mixture of this material with carbonized rice husk presented the highest water retention capacity. The use of a mixture of S-10 Beifort® with carbonized rice husk or with carbonized rice husk and coconut fiber (1:1:1) is indicated for the acclimatization of Oncidium baueri Lindl.
