Existing techniques for applying intermetallide layers are characterized by low productivity, difficulties associated with the maintenance and operation of technological equipment, as well as significant costs for the purchase of materials for spraying. Therefore, modern science shows considerable interest in the development of new, highly effective technologies to form intermetallide coatings on the surface of articles. Such promising techniques include the technology of plasma-arc spraying (PAS) of flux-cored wires.
This technique has a number of significant advantages, namely high performance, relative simplicity, as well as the affordability of equipment and materials for coating. This paper reports a study into the structure and properties of coatings obtained by flux-cored wire PAS, in which the steel sheath and aluminum powder filler interact when heated with the exothermic effect of Fe3Al synthesis. The influence of technological parameters of PAS process on the structure and properties of Fe-Al coatings was investigated by means of mathematical planning of the experiment. It was found that in all samples the main phase is an intermetallide of the Fe3Al type. Tests for gas-abrasive wear resistance at room temperature showed that the wear resistance of coatings exceeds the stability of steel S235 by an average of 2 times. As a result of studying the electrochemical properties in a 3-% aqueous solution of NaCl and in a 0.5-% solution of H2SO4, the score of corrosion resistance for these media was determined, which was, respectively, 4 and 5 (coatings belong to the group of "resistant"). In this regard, the practical use of coatings based on the Fe3Al intermetallide is recommended for protection against oxidation, corrosion, and gas-abrasive wear of components and assemblies in the heat power industry (heat exchanger pipes, catalytic converters, steam turbine blades, shut-off valves, etc.)

The object of this study is an approach to solving the problems of designing service-oriented networks that warn about emergencies using dynamic programming. The main issue is the complexity of algorithmization of processes that describe the achievement of an optimal solution in multi-stage nonlinear problems. The possibilities of applying the Bellman optimality principle for solving the set tasks for the purpose of their application in the field of engineering and technology are determined. Based on the Bellman functional equation, a model of the optimal number of sensors in the monitoring system for warning of emergencies was built.
A feature of the design is that using the classical Bellman equation, it is proposed to solve problems of various technical directions, provided that the resource determines what exactly makes it possible to optimize work in any way. Important with this approach is the planning of the action as an element of some problem with the augmented state. After that, the proposed structure in formal form extends to other objects.
A problem was proposed and considered, which confirmed the mathematical calculations, as a result of which an optimal plan for replacing the sensors of the system was obtained; and the possibilities of significant cost reduction were identified. In the considered example, an optimal plan for replacing the system sensors was compiled and the possibility of reducing costs by 31.9 % was proved.
The proposed option was used in the development of information technology for modeling a service-oriented network based on energy-efficient long-range protocols; some of the identified features were further developed in the design of a recommendation system for issuing loans and developing an interactive personnel training system

The object of this study is the production technology of bread with pumpkin paste. The task to enrich bread with pumpkin paste was resolved.
The influence of different amounts of pumpkin paste on the technological parameters of the quality of wheat bread and culinary quality was investigated. It was established that the addition of pumpkin paste influenced the technological parameters of the quality of bread. Bread baking loss decreased from 10.8 % to 9.9 with the addition of 5 % pumpkin paste. In the variant with 60 % pumpkin paste, the bread baking loss was 3.8 %. With the addition of 5–25 % of pumpkin paste to the bread recipe, bread shrinkage increased significantly to 4.2–4.3 % compared to control (3.5 %). A significantly larger volume was obtained by adding 25–30 % pumpkin paste. With this amount of paste, this indicator was 207–211 cm3/100 g of dough and 346–348 cm3/100 g of flour. With the addition of 35–60 % of pumpkin paste, the volume of bread was 330–338 cm3/100 g of flour. A significantly higher specific volume was obtained by adding 25–30 % of pumpkin paste – 2.0 cm3/g of dough and 2.3–2.4 cm3/g of bread. The addition of pumpkin paste increased the mass of bread from 133 to 135–166 g.
It was established that the organoleptic assessment of bread did not change from the amount of pumpkin paste. The smell, taste, pores in size and uniformity correspond to the highest level of assessment – 9 points. The elasticity and consistency of the crumb was at the level of 7 points. The surface of the crust corresponded to 3 points, the glossy surface – 3 points.
A distinctive feature of the research results is that in the technology of bread it is necessary to add 25–30 % of pumpkin paste. The use of this amount of pumpkin paste provides bread with a volume of 346–348 cm3/100 g of flour. The smell and taste of bread according to this recipe is high – 9 points.
The recommendations reported here can be used by small and medium size enterprises for the production of bakery
Construction of a homogeneous solution to the elasticity theory problem for an inhomogeneous truncated transversally isotropic cone
Authors: Akhmedov Natiq
Published: March 2023

Using an asymptotic integration method, this paper investigates the axisymmetric problem of elasticity theory for an inhomogeneous transversal-isotropic truncated cone of small thickness. It is believed that the moduli of elasticity are arbitrary continuous functions of the cone opening angle. It is assumed that the lateral part of the cone is free of stresses, and arbitrary boundary conditions are set at the ends of the cone, leaving it in equilibrium. Homogeneous solutions have been constructed, that is, all solutions to equilibrium equations that satisfy the condition of absence of stresses on the lateral surfaces of the cone. Three groups of solutions were derived: a penetrating solution, solutions such as a simple edge effect, as well as the boundary layer solutions. An analysis of the stressed-strained state was carried out. It is shown that the penetrating solution and solutions having the character of a boundary effect determine the internal stressed-strained state of the cone. Solutions having the character of a boundary layer are localized at the ends of the cone and its first terms are equivalent to the edge effect of the Saint-Venant inhomogeneous plate.
A particular type of inhomogeneous transversal-isotropic cone of small thickness with the degeneration of its median surface into a plane has been studied. It is shown that this case of degeneration is special, and the solutions consist of a penetrating solution and a solution of the nature of the boundary layer.
Asymptotic formulas have been derived that make it possible to calculate the stressed-strained state of an inhomogeneous transversal-isotropic cone of small thickness. On the basis of the obtained solutions, it is possible to build a new refined applied theory and determine the applicability of existing applied theories for conical shells. New classes of solutions have been identified that no applied theory can describe

Published: March 2023

Project implementation is often carried out under the influence of negative changes in the environment and circumstances characterized as crisis. Therefore, the processes associated with risk management, which is the object of this study, are becoming important. The topic of this study is to increase the efficiency of projects by adapting the project to crisis conditions, promptly developing and making effective management decisions. For projects, it is necessary not only to identify the current situation as risky but also to determine rational ways to achieve the project goals under crisis conditions. Therefore, a comprehensive method of situational project risk management based on the combined application of situational analysis methods, intelligent and expert methods, as well as Big Data technology, is proposed. Within the framework of the method, a project risk management model has been built in the form of a fuzzy situational graph, which would provide a choice of strategies that could contribute to overcoming a risky situation, as well as reduce the time to make effective management decisions in crisis circumstances. The result of this method is compliance with time constraints, reducing resource overruns and losses in the project, as well as adapting to rapidly changing circumstances and adequate response.
A comprehensive method of situational project risk management is characterized by solving the task toformalize management decision-making procedures and their information support, taking into account the availability of both structured and unstructured data. The proposed procedure for situational project risk management based on the use of Big Data technology can also be the basis of project management information technology and the corresponding decision support system

The aim of the work was to create an approach for the development of HPLC methods for the determination of meldonium in dosage forms with the usage of salts of chaotropic anions in mobile phases.

Material and methods. Analytical equipment: Shimadzu UPLC system LC-40 PDA; Shimadzu Nexera-i LC-2040C 3D-Plus, controlled by software Lab Solution version 5.97, electronic laboratory balance RAD WAG AS 200/C, pH-meter I-160MI. Meldonium dihydrate (purity 99.3 %) was purchased from Sigma-Aldrich (Switzerland), and Vasopro capsules 500 mg were purchased from a local pharmacy. Chromatographic conditions: Agilent Zorbax C-18 SB 150 mm x 4.6 mm 3.5 μm column was used (Agilent Technologies, USA). Mobile phases: 1) 0.25 % KPF6 w/v – 0.1 % v/v 85 %H3PO4 95 % – 5 % ACN, 2) 0.3 % bis-(trifluoromethane)sulfonimide lithium salt 97 % w/v – 0.1 %v/v 85 % H3PO4 80 % – 20 % acetonitrile. Flow rate - 1mL/min, T=32 °C, detection UV=at 4 channels - 190 nm, 195 nm, 200 nm, 205 nm.

Results and discussion. We have proposed two approaches using two different salts of chaotropic anions - potassium hexafluorophosphate and bis-(trifluoromethane)sulfonimide lithium salt – for the HPLC method development. The chaotropic effects of these anions toward meldonium strongly influenced the analyte migratory behaviour. Both mobile phases involved, in addition to the use of a chaotrope, also the use of acetonitrile and pH adjustment with 0.1 % v/v 85 % H3PO4 solution. The detection wavelength (190 nm, 195 nm, 200 nm, 205 nm) was selected experimentally. The results were obtained for 8 concepts. Parameters of the chromatographic system confirm the conclusions and results of this investigation for the influence of chaotropic salts on N-containing molecules in an acidic pH medium, by increasing their retentivity and improving peak shape and uniformity homogeneity, even on the column without end-capping and base-deactivating. Validation of the analytical method was carried out following the requirements of SPhU. Conclusions. HPLC methods for the determination of meldonium in dosage forms have been developed, using positive impacts of chaotropic salts on the molecules containing N-atoms in their molecule on their retentions and peak symmetries on the chromatogram. The validation of the analytical methods showed their suitability for pharmaceutical analysis

Authors: Kalmykov V. G. , Sharypanov A. V. , Vishnevskey V. V.
Published: March 2023

Context. The proposed article relates to the field of visual information processing in a computer environment, more precisely to the determination the parameters of the interest object in the image, in particular, the contour of the interest object In most cases, the contour of an object is a simply connected sequence of curve arcs.

Objective. The purpose and subject of the study is to find and to propose such a definition of the digital curve arc, as the most important element of the object contour in the recognizable image, which does not contradict modern neurophysiological conceptions about visual perception, and to recognize the object contour as a sequence of the digital curve arcs.

Method. The representation of the image in the form of a structural model is used, one of the structural elements of which is the contour of the object, consisting of digital curve arcs. Also, the image is considered as a cellular complex which corresponds to modern ideas about human visual perception.

Results. The new definition for arc of a digital curve as a sequence of digital straight segments is proposed, which does not contradict to modern concepts of neurophysiology. In contrast to the known definitions of a curve arc, the proposed definition of a digital curve arc makes it possible to determine the start and end points of the arc. According to the description of the contour of an object as a simply connected closed sequence of line segments, it is proposed to construct a description of the contour as a sequence of arcs of digital curves.

Conclusions. The use of the proposed definition of the digital curve arc in image processing makes it possible to recognize the contour of an object in an image and present it in a form close to visual perception. For best results, the use of variable resolution in image processing algorithms is recommended.

Introdução: o estresse percebido foi sugerido como um fator de risco para o desenvolvimento da Síndrome Metabólica (SM). No entanto, pouco se sabe desta associação entre mulheres. Objetivo: avaliar o estresse percebido em mulheres com SM. Materiais e Métodos: estudo transversal, a partir do recorte de um ensaio clínico não-randomizado, com pacientes de um centro de saúde público (RBR-43K52N). A variável de desfecho foi a SM, utilizando os critérios do NCEP/ATPIII. Foram coletados dados sociodemográficos, antropométricos, bioquímicos, hemodinâmicos e aplicação da PSS. Resultados: A amostra constituiu-se de 75 mulheres acometidas por SM (47,69±8,15 anos de idade; 155,65±0,07 cm; 82,43±17,79 kg; IMC de 33,54±7,28). Encontrou-se valores elevados de RCQ entre as mulheres estressadas e não-estressadas. A pontuação média da PSS foi de 27,73±9,17. Nos agrupamentos, verificou-se diferença significativa para PSS entre as mulheres estressadas e não-estressadas (35,24±5,22 e 20,42±5,53, respectivamente; p=0,001). Observou-se também que mulheres estressadas tinham níveis mais elevados de triglicerídeos e níveis mais baixos de HDL-c quando comparadas com mulheres não estressadas, embora sem diferença estatística. Discussões: Os achados sugerem que as mulheres categorizadas como estressadas tinham maior pontuação da PSS, níveis mais elevados de triglicerídeos e níveis mais baixos de HDL-c quando comparadas com mulheres não estressadas. Conclusões: a pontuação da PSS foi significativamente maior entre mulheres com parâmetros lipídicos da SM alterados, com menores níveis de HDL- e aumento de triglicerídeos.

Authors: Kreisberger Ortiz Andersson , Muñoz Ana Silvia
Published: March 2023

El objetivo principal de la investigación, a partir de la cual se genera este artículo, fue identifcar los estilos de vida y hábitos alimentarios entre adultos jóvenes de 25 a 30 años de edad, mediante un estudio comparativo con las poblaciones ubicadas en la ciudad de Pasto (Nariño) y en Pitalito (Huila).

La investigación se basó en el paradigma cuantitativo, utilizando técnicas que involucraron directamente al individuo y al fenómeno a investigar, logrando así adquirir factores precisos que se pudieran medir. Se abordó con enfoque descriptivo correlacional lo que permitió comparar los resultados en las dos ciudades; además, se realizó mediante un diseño transversal, teniendo en cuenta a su vez el aspecto correlacional, puesto que la encuesta se aplicó a la población y posteriormente se llevó a cabo una descripción de los resultados en relación con las diversas variables y la teoría.

Entre los rasgos relevantes del grupo objeto de estudio están el grado de escolaridad, dado que una parte considerable de la población tenía nivel profesional, y el estado civil, puesto que en gran porcentaje resultaron ser solteros. Por otra parte, para la obtención de datos se utilizaron instrumentos como el Cuestionario de Perfl Estilo de Vida [PEPS-I], el Cuestionario Internacional de Actividad Física [IPAQ] y el Cuestionario de Frecuencia de Ingesta de Alimentos [CFIA].

En cuanto a los datos recolectados del estilo de vida, se evidencia que mantienen la califcación positiva, teniendo en cuenta que se evaluaron aspectos de nutrición, ejercicio, niveles de actividad física, manejo del estrés, autoactualización y soporte interpersonal, en este último aspecto se encuentra una diferencia entre las dos regiones; paralelamente a ello se recolectó información sobre los hábitos alimentarios, donde se reﬂeja mínimamente la diferencia en el consumo de algunos alimentos entre las dos zonas.

Se concluyó que los grupos estudiados en los dos municipios presentan grandes diferencias en cuanto a estilos de vida y hábitos alimentarios, siendo inﬂuenciados por aspectos como las condiciones geográfcas (clima, población total), condiciones de vida, escolaridad y el estrato socioeconómico.

Current migratory movements have been mostly connected with the refugee crisis initiated in 2015, the deliberate actions of the government of Belarus in 2021 and the Russian invasion of Ukraine in 2022. It should be assumed that the pursuit of people towards the area of security is associated with multiple threats and challenges both for themselves and for their surroundings. The problems concern countries of departure, transit and destination. In each of these “stages” there are multiple threats affecting not only the refugees themselves. The main problem is the identification and analysis of threats, which would allow to define the conditions for strengthening the area of security related to migration. Threats concern both the life and health of people on the move (death in transit, loss of health, exposure to criminal and extreme political circles, involvement in criminal activities, economic exploitation, ethnic and religious animosities and conflicts) and for the institutions of states (social assistance, internal security). Global events indicate that threats, problems and challenges will continue to exist. It is therefore necessary to adapt the forms of institutional actions towards the problem in order to neutralize the indicated threats.
Role theory and Russia’s attempts to integrate the post-Soviet space: from internal to international duties
Authors:   Cracow University of Economics, Strycharz Damian
Published: March 2023

With the Russian invasion of Ukraine in February 2022, Moscow’s foreign policy towards the post-Soviet space has become an even greater area of concern. In order to better understand Russia’s behaviour in the post-Soviet space, it is worth analysing what led to Moscow’s renewed interest in this area. There are numerous accounts explaining Russia’s policies towards its neighbourhood, but they often focus on material factors or Russian imperial complexes. To address the existing gap and examine changes in Moscow’s attitude towards the region, this paper will use role theory and analyse shifts in Russia’s national role conceptions. It argues that the combination of important external and internal factors led to changes in perception of Russia’s international duties and responsibilities between Putin’s rise to power and his return to the presidency in 2012. Consequently, these changes resulted in different understanding of Russia’s role in the post-Soviet space, which had implications for Russia’s increasingly aggressive actions in the region afterwards.
Trade Flows Between the European Union and the Eastern Partnership Countries: Dynamics and Prospects
Authors:   Nicolaus Copernicus University in Torun, Grodzicki Tomasz
Published: March 2023

The Eastern Partnership is a part of the European Neighbourhood Policy focusing on the EU’s Eastern neighbours. Its main objective is to deepen the political and economic integration of the EU with six countries in Eastern Europe and the South Caucasus: Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine. The aim of this paper is to assess the development of EU trade relations with Eastern Partnership Countries from 2002 to 2021 and to indicate its prospects. The results show that the EU is in a group of main trading partners of the Eastern Partnership countries. The EU noticed both: a trade surplus with Belarus, Georgia, Moldova, Ukraine and Armenia (except in 2005); and a trade deficit with Azerbaijan. The volumes of imports and exports had increased over the years which also led to better economic integration with the EU. However, the future EU-Eastern Partnership trade characteristics and dynamics remain unknown due to the Russian invasion on Ukraine that caused troubles in trade flows in Ukraine and economic sanctions on Russia and Belarus.

ABSTRACT Objective: to assess the epidemiological profile of trauma patients from fall from the same level (FSL) and fall from an elevated level (FEL) during the COVID-19 pandemic, and to compare it with data from different levels of restriction (flags) and data prior to the pandemic. Method: a cross-sectional study with a probability sample of the medical records of patients aged 18 years or older admitted to the emergency room due to falls, from June 2020 to May 2021. Epidemiological data, such as sex, age and injuries were analyzed, as well the current level of restriction. The three restriction periods were compared between then and the proportion of admissions due to falls was compared with the period from December 2016 to February 2018. Results: a total of 296 admissions were evaluated, 69.9% were victims of FSL and 30.1% of FEL. The mean age was 57.6 years, and 45.6% were over 60 years old. Admissions among men predominated, and 40.2% of patients required hospitalization. During the red flag period, there were proportionally more injuries to the head and neck (p=0.016), injuries to extremities (p=0.015) and neurological trauma (p<0.001). An average of 6.1, 6.3 and 5.2 admissions per day was obtained during the yellow, orange and red flag, respectively. There was a relative increase in falls when compared to the pre-pandemic period. Conclusions: there was an absolute reduction in admissions of victims of falls in midst of the most restrictive period during the pandemic. However, when compared to pre-pandemic data, there was a relative increase in falls.

Resumo O presente ensaio pretende discutir alguns caminhos para o trabalho de psicanalistas diante de situações de violência e de violações de direitos, na escuta de sujeitos que passam por experiências traumáticas. Para isso, apresenta a relação entre trauma e temporalidade, e discorre sobre os desafios transferenciais da escuta nessas condições. As reflexões propostas partem da experiência com o projeto Casa dos Cata-Ventos, uma estratégia de atenção à infância e à adolescência ancorada na ética psicanalítica. É apresentada uma discussão acerca do método de trabalho desenvolvido, o qual se propõe a operar com o tempo em sua rearticulação. Destaca-se que tais estratégias construídas possibilitam a criação de um tempo narrativo, em que se pode falar e historicizar o que se viveu e, assim, oferecer um contraponto à temporalidade do trauma.

Published: March 2023

ABSTRACT In the Brazilian Semi-arid Region, extensive livestock farming with ecoproductive management is the most efficient way to maintain and increase the production of goat products (e.g., meat) with of not depleting environmental resources. This set of actions (induced goat migration and pasture closure) is part of Livestock 4.0, in which Industry 4.0 feed areas are efficiently managed using artificial intelligence and deep learning properly monitored by the producer and the consumer. The objective of this work was to identify pasture areas with Opuntia ficus-indica (Mill, Cactaceae) forage palm species for breeding and production of Capra aegagrus-hircus goats (Lineu, Bovidae) using aerial survey images captured by drones classified using deep learning techniques. The methodological steps of the Industry Architecture Reference Model 4.0 were adapted to the field situation (Semi-arid Region) including (A) study area delimitation, (B) image collection (by drones), (C) deep learning training, convolutional neural network (CNN) training, (D) training accuracy analysis, and (E) automatic goat production evaluation and validation. The area classification based on the forage palm density allowed us to measure the environmental degradation caused by livestock. Stimulated goat migration reduced this degradation as well as increased goat biomass and volume production.

Published: March 2023

Com este estudo pretendemos conhecer melhor o impacto da Doença de Alzheimer (DA) na linguagem, mais concretamente o impacto no contexto da utilização do sujeito nulo. Analisamos as produções de doze pessoas com DA e de um grupo de controlo com a mesma dimensão, em tarefas de leitura de três tipos de frases: Simples com verbo em tempo simples; simples com verbo conjugado num tempo composto; complexas formadas por duas orações. As frases, traduzidas de um estudo prévio em italiano e inglês, foram repetidas ao longo de três dias por cada um dos participantes e gravadas para posterior tratamento de dados. As pessoas com DA apresentaram um desempenho inferior em relação ao grupo de controlo, sendo, no entanto, algumas diferenças entre os dois grupos, não significativas. Os dados recolhidos em Portugal quando comparados com os do estudo efetuado em Inglaterra, permitiram concluir que as pessoas com DA têm uma maior tendência para a produção de sujeitos nulos, tendência que se verifica com maior predominância nas frases mais longas e mais complexas. Os participantes portugueses apresentaram também uma menor tendência para a produção de sujeitos nulos do que os italianos.
O QUE É BEM-ESTAR SUBJETIVO? ANÁLISE CRÍTICA DO ARTIGO SUBJECTIVE WELL-BEING DE ED DIENER
Authors: Sewaybricker Luciano Espósito , Massola Gustavo
Published: March 2023

Resumo: O artigo de Ed Diener “Bem-Estar Subjetivo”, fundamental para a consolidação desse objeto na Psicologia Positiva, foi analisado criticamente em sua consistência interna e em sua influência para essa nova área. Cada bloco textual do artigo foi avaliado quanto a sua fragilidade segundo três categorias: consideração teórico-filosófica, definição do conceito e suas partes, referências bibliográficas. Como resultado, destacamos que Bem-Estar Subjetivo (BES) e Felicidade são fragilmente definidos no artigo, dando margem a ambíguas interpretações que se prolongam até o presente; importantes perguntas, como a diferença entre a melhor vida e a vida boa, são ignoradas; importantes referências bibliográficas são utilizadas inconsistentemente. Todavia, reconhece-se que as fragilidades identificadas no artigo são coerentes com o projeto da Psicologia Positiva: enfatizar aquilo que é mensurável ao custo do rigor. Recomenda-se que pesquisas sobre BES resgatem a história dos conceitos centrais a fim de reconhecer seus próprios limites e solucionar problemas éticos do campo.

Resumen: La vejez de las mujeres mayores suele ser descrita como una etapa en la que se vivencian múltiples cambios y pérdidas, donde se acrecientan las discriminaciones de género. Sin embargo, poco se ha explorado la experiencia biográfica al envejecer. En este artículo, identificamos como construyen narrativamente trayectorias de acción política mujeres mayores activistas de la Agrupación Bordadoras por la Memoria de la ciudad de Valparaíso-Chile. Realizamos un estudio cualitativo con entrevistas biográficas siguiendo la propuesta de relatos de vida. Sus itinerarios biográficos dan cuenta de un continuum en su acción política y un cuestionamiento al sistema neoliberal. Por medio de sus bordados, contribuyen a la lucha por la memoria y la justicia social. Resignifican su activismo en la vejez, incluyendo nuevos repertorios de acción y proyectos, mediante prácticas de sororidad. Concluimos la importancia de disputar la vejez desde el ciclo vital convencional, dando cabida a trayectorias femeninas agencializadas.
O Ministério Público Federal: de Defensor de Direitos a Combatente da Corrupção (1988-2018)
Authors: Kerche Fabio , Viegas Rafael Rodrigues
Published: March 2023

Esse artigo trata da mudança institucional do Ministério Público Federal (MPF) de instituição defensora de direitos para combatente da corrupção. Tem um duplo objetivo: primeiro, empírico, é demonstrar que os constituintes não tinham a corrupção como uma preocupação relevante, mas que, a despeito disso, a atuação do MPF priorizou o combate à corrupção nos anos 2000 em detrimento de outras atribuições igualmente relevantes; b) segundo, analítico, é analisar e discutir as mudanças institucionais incrementais depois 2003 que explicam o MPF como combatente da corrupção. Para tanto, realiza-se análise de conteúdo de documentos oficiais da Assembleia Nacional Constituinte, dos resultados de dois surveys com membros do MP, aplicados em 1996 e em 2016, e dados das atividades extrajudicial e judicial do MPF entre 2012 e 2018. Conclui que uma combinação de fatores exógenos e endógenos facilitou a mudança institucional, no entanto existe um modelo institucional que permite maior autonomia e discricionariedade, que, em determinado contexto, pode ser utilizado, por exemplo, contra o sistema político.

In this study, we investigated the abrasive wear behavior of carbon black (CB)/bio-char reinforced polymer composites. A pyrolysis/gasification technique was used to produce CB filler at high temperatures from orange peel particulates, a biowaste material, under controlled or oxygen-free conditions. In the abrasive wear test, the composite samples were fabricated by a hand lay-up technique using different percentages by weight (wt%) of the CB filler loadings (5%, 10%, 15%, and 20%). The wear behavior was successfully investigated using a pin-on disc apparatus. The effects of the carbonization temperature, filler loadings, and normal load on the sliding wear behavior of the fabricated specimens were investigated. It was observed that the tribological behavior of the polymer composite material was enhanced by incorporating the CB filler material, where optimal results were observed at higher carbonization temperatures (800°C). Sliding wear tests were performed at room temperature under various loading conditions (5,10,15, and 20 N) and different filler loadings (wt%), where optimal results were obtained for the 20 wt% filler loadings. From the experiment, it was observed that the abrasive wear resistance was enhanced by 67% and 70% by incorporating CB filler material at carbonization temperatures of 400°C and 800°C, respectively. A microstructure analysis of the worn surfaces was done by scanning electron microscopy to investigate the wear behavior of the specimens.

Coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 is characterized by acute respiratory distress syndrome (ARDS) facilitated by cytokine storm and other risk factors that increase susceptibility and complications leading to death. Emerging as a major global public health challenge, the disease has claimed more than 6 million lives and caused catastrophic global economic disruptions. However, there are concerns about the safety as well as the efficacy of drugs and vaccines presently used to control the pandemic, therefore necessitating intense global search for safe natural products that can effectively and safely combat it. This work reviews studies on lingzhi or reishi medicinal mushroom, Ganoderma lucidum and its properties that may potentially combat SARS-CoV-2 infection and the co-morbidities. Available evidence suggests that medicinal properties of the Ganoderma mushroom can combat the complications of SARS-CoV-2 infection and the co-morbidities that can aggravate the severity of the disease. Preclinical and clinical evaluation to establish dose, efficacy, and potential toxicity and possible use in the management of COVID-19 is recommended.

Published: March 2023

In this study, the electrical energy consumption of an apartment building was calculated depending on different design parameters. The electrical energy consumption was found according to the population information of each of four cities selected to represent different climatic regions. The calculations took into account, firstly, the application of different insulation materials; secondly, the state of the building: discrete, surrounded by trees or adjacent to another building; and, thirdly, different glazing types. Using the Taguchi method, experimental designs were conducted for each representative city. Then, the most suitable building design parameters were determined for each city according to signal-to-noise ratios. In the study, pollutant emissions, such as carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NO x ) and particulate matter, released to the atmosphere were investigated. It was observed that there was a 50% reduction in energy consumption and emissions based on the most suitable building design parameter determined by the Taguchi method.

Development and successes of the physical science of strength and durability allow us to formulate the main aspects of dislocation physics. In this paper, the current state of this issue is considered within the framework of a multilevel approach – patterns of dislocations accumulation in the material after deformation with various degrees. The main mechanism of hardening of a metallic polycrystal is the dislocations accumulation in its grains, and the main parameter of hardening is the average scalar density of dislocations. The scalar dislocation density is divided into components: the density of statistically stored (ρS ) and the density of geometrically necessary (ρG ) dislocations. Transmission diffraction electron microscopy (TEM) is used to study the stages of development of types of dislocation substructure (DSS) in Cu – Mn alloys depending on concentration of the alloying element during active plastic deformation. Polycrystalline alloys were studied in a wide concentration range: from 0.4 to 25 % Mn (at.). A number of dislocation substructure parameters were measured using the images obtained on an electron microscope: the average scalar density of dislocations
, the density of statistically stored (ρS ) and geometrically necessary (ρG ) dislocations, the curvature-torsion of the crystal lattice (χ), the density of microstrips (Рstrips ), the density of ragged sub-boundaries (Мrag.bound. ). The authors established the effect of the sequence of DSS types transformations with an increase in the degree of deformation and the second element quantity on formation of the type of substructure and its parameters. Influence of concentration of the second element and the grain size on the average scalar density of dislocations and its components was experimentally determined. The presence of disorientations in the substructure during deformation is based on the measurement of these parameters by the TEM method.

At present, powder with spherical particles from corrosion-resistant steels is used in such widespread additive methods as selective laser melting, selective laser sintering, direct laser sintering, electron beam melting, and others. Each of these methods places high demands on the characteristics of the spherical particles of stainless steel powder. This article is devoted to the production of a spherical powder by plasma spraying of a wire with diameter of 1 mm from corrosion-resistant steel 03Kh17N10M2 and the study of powder characteristics on its suitability for the use in additive methods. The authors developed the technology for obtaining a spherical powder and studied the influence of spraying modes on the yield of fraction less than 160 μm, suitable for additive methods. With an increase in power and gas flow, the yield of fraction less than 160 μm increases and reaches more than 70 %. The resulting powder has high fluidity (17.6 ± 1 s), bulk density (4.15 ± 0.1 g/cm3 ) and density after tapping (4.36 ± 0.2 g/cm3 ) and is suitable for use in additive production. Influence of the spherical powder fraction on the fluidity, bulk density and density after tapping was also studied. The best characteristics were obtained for the –90 μm fraction: fluidity 16.64 ± 1 s, bulk density 4.16 ± 0.1 g/cm3 and density after tapping 4.38 ± 0.2 g/cm3. These figures meet the requirements for powders used in additive manufacturing, namely, the fluidity of 50 g of powder is less than 30 s and the bulk density is more than 3 g/cm3.
