A CONSTITUIÇÃO DA IMAGEM E AS ESTRATÉGIAS DE LEGITIMAÇÃO POLÍTICA NO DISCURSO DE JAIR BOLSONARO NA CÚPULA DE LÍDERES SOBRE O CLIMA
Authors: Nascimento Jarbas Vargas , Pereira Danilo Adler 
Published: July 2024

Este artigo tem como tema o estudo do discurso político de Jair Bolsonaro, pronunciado na Cúpula de Líderes sobre o Clima, em 22 de abril de 2021. De um lado, a Cúpula realça a importância dos Estados Unidos com Biden, influenciando a questão climática e, por outro, a pressão sobre o Brasil, desmoralizado pela política de meio ambiente imposta pelo governo. Parte-se do pressuposto de que a Política e o discurso político se organizam por meio de interligações entre o campo de ação e o lugar das trocas simbólicas, organizado segundo relações de poder. De fato, o enunciador do discurso político cria uma encenação, onde sua ação e seu posicionamento se unem ao sujeito social, para constituir uma imagem positiva de si, legitimar-se e empoderar-se. Nesse sentido, o político é reconhecido por seus interlocutores por meio de uma identidade social e subjetiva pré-construída e, embora saiba, esforça-se para mostrar seu poder por meio de uma identidade discursiva, que ele constrói para si próprio. Considerando essas questões, tem-se como objetivo examinar a imagem do sujeito político, que ele partilha com os seus interlocutores e a forma como constrói para si um ethos em meio às normas sociais, que garantem a eficácia de seu discurso. Para fundamentar a análise do corpus, apoia-se na Análise do Discurso de linha francesa, na perspectiva Semiolinguística de Charaudeau, que postula que o discurso político se constitui por seu conteúdo, nas condições criadas pela situação de comunicação. Os resultados da análise apontam que o discurso de Bolsonaro na Cúpula dos Líderes do Clima encobre sua ação política, destoa das práticas de seu governo em relação ao meio ambiente e ao aquecimento global e objetiva confundir seus interlocutores.

Septic shock in obstetrics: the role of efferent techniques for endotoxin removal in Gram-negative sepsis
Authors: Bayalieva A. Zh. , Davydova V. R. 
Published: July 2024

Aim: to assess the sorption capacity of various devices for endotoxin removal modelled in in vitro patient with septic shock experiment.Materials and Methods. Endotoxin adsorption was evaluated in vitro by using circulating endotoxin solution in bovine serum in a closed circuit. The following columns were chosen for the experiment: Toraymyxin PMX-20R (РМ Х), Alteco® LPS Adsorber, Efferon LPS, Toray Filtryzer BK-2.1U. Lipopolysaccharide (LPS) doses corresponding to severity of the septic process were sequentially added to a column pre-washed with physiological solution. The first LPS dose of 12.5 µg was added to a flask containing 1500 ml (1.5 L) of fetal bovine serum, a second LPS dose of 37.5 µg was added at 120 minute; the serum samples were collected before the onset of experiment, as well as 30, 60, 120 (before the second dose), 120 (after the second dose), 150 and 240 minutes after the start of circulation. LPS measurement was carried out by mixing the prepared serum sample with LAL reagent at 1:1 ratio in a measuring tube.Results. All columns can reduce endotoxin levels below the 12.5 µg and even 50 µg levels, although none of devices were able to reduce the LPS level from “supercritical” 50 µg to “critical” 12.5 µg. However, at the same time, the capacity of the Toraymyxin PMX-20R column turned out to be 5-13 times greater than that of other products. This result suggests that while removing endotoxin under similar conditions, the Toraymyx in PMX-20R column will have a much higher reserve of sorption capacity and, therefore, greater opportunities for lowering a risk of septic shock progression.Conclusion. The study we presented provides insights into whether sorption capacity of the tested cartridges is sufficient to remove endotoxin at initial (12.5 µg) load that corresponds to the onset of systemic inflammatory response syndrome in a typical patient. Additionally, it elucidates to what extent a cartridge can reduce the endotoxin load in severe septic shock with a total LPS load of up to 50 µg.

Abstract
Seismic tomography harnesses earthquake data to explore the inaccessible structure of the Earth. Adjoint waveform tomography (AWT), a method of seismic tomography, updates the tomographic model by optimizing the fit between observed earthquake data and synthetic waveforms. The synthetic data are calculated by solving the wave equation through a given 3D model. An important requirement to calculating synthetics is the source information (location, centroid time, depth, and moment tensor). Errors in source information affect the quality of the synthetics produced, which in turn can limit how structure can be inferred in the AWT workflow. To test the effect of updating source information, we used MTTime (Chiang, 2020), a time-domain full-waveform moment tensor inversion code, to calculate the moment tensors and depths of 118 earthquakes that occurred in California and Nevada over a 20-yr period. We calculated 3D Green’s functions using a 3D seismic wavespeed model of California and Nevada (Doody et al., 2023b). We show that the inverted solutions provide better waveform fits than the Global Centroid Moment Tensor catalog and increase usable, well-correlated data by up to 7%. Therefore, we argue that recalculating source parameters should be considered in AWT workflows, particularly for smaller magnitude events (Mw&lt;5.0).

Introduction: Gastric cancer is one of the most common oncological diseases in the world, occupying the 5th place of morbidity and the 3rd place in the structure of mortality from oncological diseases. For a long time, issues affecting the risk of developing cancer after bariatric surgery remain relevant. Our observation is devoted to the diagnosis and treatment of a patient with gastric cancer after gastric bypass. Description of the clinical case: A 62‑year‑old patient was operated on 13. 07. 2016 – laparoscopic Roux gastric bypass for morbid obesity, 11. 09. 2019 – laparoscopic installation of the Cardioplant plate on a small stomach due to recurrent weight gain. Since 2020 the patient had the phenomena of anastomositis, dysphagia and gastroesophageal reflux. Courses of conservative therapy, sessions of balloon dilation of gastroenteroanastomosis and anastomosis resection failed to show a significant effect. The patient underwent comprehensive examinations at each treatment, including abdominal MSCT, cancer markers and studies of biopsy material of the gastric mucosa and gastroenteroanastomosis. As a result of histological studies, no signs of cancer were found. After applying to the Avicenna Medical Center in 2022 a molecular genetic analysis was carried out, in which the mRNA panel most corresponded to a malignant neoplasm. 20. 12. 2022 extirpation of the stomach stump with resection of the esophagus was performed. The cancer diagnosis was confirmed by histological and immunohistochemical studies: low‑grade adenocarcinoma of the stomach with a cricoid component with germination into the esophagus and small intestine, with spread beyond the muscle layer. Conclusion: This clinical case highlights the complexity of oncological verification in patients after bariatric surgery. Prolonged dysphagia, anastomositis and recurrent GERD in such patients determine the need for a more detailed examination, including the latest achievements of molecular genetic analysis.

El presente artículo analiza el fenómeno de surgimiento de un conjunto de organizaciones (empresas) en un espacio y tiempo específico, generando una nueva actividad económica. Se trata del caso de las empresas conformadas en torno a la actividad piscícola con las cuales se estableció una novedosa dinámica económica en una región periférica de lento desarrollo económico, ubicada al sur de Colombia. El estudio fue de carácter cualitativo de tipo documental inventariando fuentes primarias y secundarias con las cuales fue reconstruida la trayectoria de la actividad piscícola en Colombia y el departamento del Huila. Como conclusión se puede afirmar que el surgimiento de la piscicultura se da por el concurso de una política de fomento a la explotación piscícola adelantada por el Estado, instituciones públicas y gremiales del sector agropecuario; la existencia de un marco regulatorio que permitió la actuación de organizaciones dedicadas a la actividad; los aportes tecnológicos y científicos divulgados por entidades multilaterales y entidades públicas descentralizadas que impulsaron mejoramientos genéticos y alimenticios; y el deterioro de la pesca tradicional continental que permitió una demanda orientada hacia productos piscícolas.

A comprehensive study of the technical condition, corrosion processes, damage and load-bearing capacity of the reinforced concrete chimney pipe, which removes the gas-smoke mixture formed in the technological processes of coke-chemical production and is an aggressive environment, was performed. A methodology for predicting the remaining resource of the pipe structure has been developed. It was established that the damage that determines the ultimate resource is the collapse of the lining, after which active corrosion damage of the reinforced concrete structure occurs. An analysis of the composition and temperature-moisture regime of the aggressive medium was performed. It was established that it is gaseous, the most aggressive components of which are acid gases, the degree of aggressive action is moderately aggressive, possibly strongly aggressive. Corrosion of concrete progresses in a concentric front from the inner surface of the chimney to the outer surface at a rate of 1.2 to 4.8 mm/year. The corroded layer of concrete loses its strength and protective properties to the reinforcement. An analysis of the stress-strain state of the pipe taking into account corrosion damage was performed, the most heavily loaded dangerous zone and its structure were determined, and the limit values of the wall thickness and the depth of corrosion damage in this zone were determined, which ensure the fulfillment of the conditions for bearing capacity. Based on the values of the corrosion rate, the time to reach the limit state is determined. It is shown that without repair and protection measures, the remaining service life of the pipe does not exceed 11 years. It is recommended to carry out a major repair of the pipe as soon as possible with the elimination of damage and restoration of the lining, or no later than after 10 years to carry out the liquidation of the structure with the construction of a new one.

The purpose of leveling the route is to determine the elevations of all the control points, including the beginning, middle, and end of curves, plus points, and points on transverse profiles. Longitudinal and transverse leveling is carried out after the route has been set out. The results of leveling (elevation measurements) are subsequently used for constructing the longitudinal profile of the route and the transverse profiles.The paper outlines the main principles and methods of leveling, taking leveling readings on rods, referencing the road route to benchmarks, leveling junction and intermediate points, balancing elevation differences, and calculating junction and intermediate points. The paper also describes the control of route leveling and plotting the projected line on the longitudinal profile.Engineering-geodetic surveying, specifically geometric leveling of the route, is an important component of educational geodetic practice. Geodetic practice for students is conducted according to the academic curriculum and serves as a continuation of the learning process in the field. It completes the theoretical course and is conducted according to the academic plan. During practical training, students acquire skills in working with geodetic instruments and processing the results of field measurements, becoming familiar with the main types of engineering-geodetic work during surveys and construction of engineering structures. Students are required to participate in all types of work, conduct the necessary measurements, and process them in the office.
Practical training in geodetic practices provides students with hands-on experience in applying theoretical knowledge to real-world scenarios. Through fieldwork, students gain proficiency in using a variety of geodetic instruments such as levels, total stations, and GPS receivers. They learn how to set up and operate these instruments accurately to collect precise measurements of elevation and distance. Furthermore, students learn the importance of teamwork and collaboration during field surveys. Working together with peers, they divide tasks, communicate effectively, and problem-solve on-site challenges that may arise. These collaborative experiences not only enhance their technical skills but also cultivate essential soft skills such as leadership, communication, and adaptability.

In particular, the growth in rail freight transportation is largely due to the expansion of the sea corridor through the Danube ports. This has made it possible to export Ukrainian products to Europe and other regions of the world, which has stimulated growth in demand for rail transportation. Due to the expansion of the maritime corridor and the change in the geopolitical situation, the share of export cargo transported by rail has increased significantly. These are primarily grain, oilseeds, metallurgical products and chemicals.Induced analyzes scientific research related to the issues of improving the efficiency of mass cargo transportation by rail. Such important problems as the problem of timely provision of loading resources, delays in transportation, inefficient use of empty vehicles, loss of cargo during transportation, etc. are considered. Ways to solve these problems, which are considered in the works of scientists, include infrastructure modernization, introduction of new technologies and optimization of logistics processes.The question was raised the issue of the efficiency of using container and containerized transportation technology. Their advantages, such as reduction of time and costs for transportation, environmental friendliness, are shown, and their disadvantages are considered.The mathematical model of the movement of a container train is analyzed and the feasibility of creating dry port-type structures for optimizing the transportation of mass cargo is investigated.These researches point to the need for a systematic approach to improving the efficiency of mass freight transportation by rail, taking into account various aspects, including technological, infrastructural, logistical and organizational aspects. Such an approach will allow achieving a higher level of efficiency and competitiveness of rail transport in the transportation of mass cargo.Proposed measures for improve the efficiency of mass cargo transportation by rail: optimization of routes, increasing energy efficiency and carrying capacity of railcars, modernization of infrastructure, use of the latest technologies, optimization of loading and unloading, and improvement of safety and quality of service.
DEVELOPMENT OF A MATHEMATICAL MODEL FOR DETERMINING TRACTION AND ENERGY PERFORMANCE INDICATORS OF A MANEUVERING LOCOMOTIVE
Authors: Gorobchenko Oleksandr , Zaika Denys 
Published: July 2024

Fuel consumption for traction significantly depends on the locomotive's operating mode, and by selecting a rational mode during station maneuvers or transit, it is possible to reduce fuel consumption. Previous works on this topic do not provide sufficient analysis of locomotive motion with varying numbers of connected engines. To optimize energy resource consumption, a combination of methods for the rational use of the locomotive is necessary. The traction and energy performance indicators for the maneuvering work of the ČME3 locomotive are calculated by performing traction calculations. In this paper, a mathematical model has been developed to determine these indicators when operating with 4 and 2 parallel-connected traction electric motors. Graphs were constructed to illustrate the relationship between traction force and locomotive speed, the time required to cover a given distance, fuel consumption for a specified distance, and the temperature rise above ambient conditions concerning 6 parallel-connected traction electric motors for the 3rd, 4th, and 5th positions of the engineer's controller. The locomotives were compared while covering the same stretch of track with the same train weight, considering wheel-rail adhesion constraints.Analyzing the obtained dependencies allows the conclusion that using different configurations of connected engines can result in fuel savings of up to 15 % during maneuvering operations, depending on operational conditions. Furthermore, the engine temperature remains within acceptable limits for insulation class F, based on the results of approximating existing locomotive characteristics and deriving analytical expressions (6, 7, 8, 24). Mathematical models of the motion of the ЧМЕ3 locomotive were created for various engine connection scenarios using the obtained mathematical formulas (9, 10, 11, 13, 20, 21, 22, 23, 24).

Published: July 2024

Autonomous voltage inverters with PWM, which are used in electric drive systems with brushless motors, occupy an important place in the complex of electrical equipment of modern traction rolling stock of railways. The article presents the results of the research of the traction three-phase bridge voltage inverter with soft switching of power switches. Using the soft switching mode allows you to reduce the switching losses in the power transistors of the keys, increase the PWM frequency and improve other performance indicators of the converter. It is advisable to implement soft switching in the key transistors of the three-phase voltage inverter using soft switching nodes with fast-acting four-quadrant switches based on IGBT.
It is proposed to consider the possibility of using transistor switches of a voltage inverter with capacitive non-dissipative snubbers at high PWM frequencies. For this purpose, a synthesis of the scheme and algorithm for the implementation of soft switching in a three-phase bridge voltage inverter with bipolar sinusoidal PWM with soft switching nodes with high-speed four-quadrant switches based on IGBT was performed. An analysis of the characteristics of the three-phase voltage inverter was carried out when using high-speed switches in the soft switching nodes to implement soft switching in the power transistors of the inverter switches.On the basis of the study, it is proposed to modernize the scheme of the soft switching unit in order to provide better preparation for the switching of the power transistors of the keys at large load currents. The improved soft switching unit includes low-voltage sources of constant voltage, which will compensate for energy losses in the recharging circuit of the snubber capacitors and contribute to the soft switching on of the power transistors of the voltage inverter keys. The performance test was carried out and the characteristics of the converter were analyzed when using a modernized soft switching node using simulation modeling in the MATLAB package.

Published: July 2024

The construction of houses of worship in some areas of Indonesia often causes social conflict. In some cases, the conflict of houses of worship can be resolved well and some are not resolved. The establishment of houses of worship in Tangerang Regency, Banten Province, namely the construction of HKBP Rogate, GKBJ Sepatan, and GBI Tanjakan churches also triggered the social conflict. This article aims to reveal the chronology of the conflict over the construction of the three churches and the local government's actions in overcoming the conflict issues that arose. These three cases were studied by researchers using a qualitative approach and analyzed using the CGR (Collaborative Governance Regime) model. This CGR model analysis is part of the early response of the parties related to the conflict and can reveal the weaknesses, and strengths in the conflict resolution of the establishment of houses of worship. The data collection method uses interview techniques and documentation studies. The findings of this research show that in the three cases of conflict, two cases show an escalating conflict (the emergence of mass action), and one case does not escalate. Conflict resolution against the establishment of the three houses of worship by the government and community leaders can prevent conflict escalation in the form of mass mobilization if the parties succeed in identifying problems at the location. Identification of parties who have the authority to determine the final direction of the conflict, especially those who reject the presence or establishment of houses of worship, is important in conflict resolution efforts. The success of conflict resolution efforts depends on the involvement of all parties who are authorized to determine the end of the conflict.
