The study objective is to substantiate the possibility of using products made of composite materials instead of metals in the automotive industry, in particular, for air tanks of the braking system of KAMAZ vehicles.
The problem to which the paper is devoted is to provide the possibility of replacing metal products of the car braking system with products made of composite materials, for example, for air tanks.
Research methods. A mathematical model of the loading conditions of heated cylindrical shells of vessels made of composite materials under axial loading is substantiated, the basics of some issues to use cylindrical shells in the problems of dynamic deformation of shell structural elements are justified.
The novelty of the work. For the first time in the automotive industry, the possibility is theoretically and experimentally substantiated to replace metal products with products made of composite materials, which in terms of their technical characteristics, weight, temperature and strength are not inferior or superior to metal ones, in particular, ensuring corrosion resistance, tightness and safety.
The results of the study. As a result, it was found that after removing the load and cooling down, the walls of the shells remain in the same position which they occupied at the time of buckling, and the surface disintegration in the area of the wave crests was not detected. However, upon visual inspection of the cross-sections of the shells, wall delamination is observed, with increasing temperature, the value of the critical load decreases and tends to zero at a certain limit temperature.
Conclusions: The studies conducted allow to conclude that in terms of weight, temperature and strength characteristics, composite materials are not inferior and even superior to metal ones in ensuring corrosion resistance, tightness and safety of operation. In the automotive industry, products made of composite materials can improve the reliability and safety of vehicle systems, including braking, reduce accident rates for transport processes, reduce injuries and death of people.

Published: July 2022

The chapter is devoted to the study of the role of educational ecosystems and medical educational ecosystems in the development of «soft skills», according to students, doctors and teachers of a medical university. The topic is very relevant in view of the fact that in recent years there has been an active development of educational ecosystems. And, despite the fact that approaches to the educational process and many requirements for specialists change from time to time, the concept of «flexible skills» remains very relevant, including for educators and medicine, and even more so for doctors involved in the training of young professionals. The objects of the study were 150 people, men and women, divided into 3 groups of 50 subjects, depending on belonging to a particular community. Group 1 included 50 medical students enrolled in the 4th year of the medical faculty of VGMU N.N. Burdenko. The second group included 50 practicing physicians of the VRCH №1 of various specialties (both surgical and therapeutic). Group 3 included employees of various departments from among the teaching staff of the VGMU N.N. Burdenko. The basis of the study was an anonymous questionnaire developed by the authors, which includes both some personal questions – age and work experience, and specifically aimed at determining the level of awareness of the respondents about educational ecosystems and medical educational ecosystems, about the level of knowledge about «soft skills», with ranking from more significant to less significant for their practical activities, as well as including issues of satisfaction with the current education system and opportunities for improved mastery of «soft skills» through educational ecosystems. The data obtained can significantly help in understanding the importance of modern educational ecosystems and medical educational ecosystems for better and faster mastering of soft skills.
Odio, polarización social y clase media en Las Mañaneras de López Obrador
Authors: Ramírez Plascencia David , Alonzo González Rosa María , Ochoa Amezquita Alejandra 
Published: July 2022

El odio se ha convertido en un elemento clave en el discurso de los políticos populistas para apoyar su agenda. Tal es el caso del presidente mexicano, López Obrador (AMLO), quien ha utilizado medios de comunicación oficiales y redes sociales para acosar a sus críticos y a la oposición política. Un elemento distintivo en su estrategia mediática es “La Mañanera”, una conferencia matutina en la que se informa sobre la agenda presidencial, sin embargo, este espacio ha servido también para exculpar a sus familiares y militantes de su partido, así como para criticar a periodistas, organizaciones sociales, opositores y, desde el segundo semestre de 2021, a la clase media mexicana. El propósito de este artículo es emplear el corpus teórico del Enfoque Discursivo-Histórico (DHA) para estudiar la construcción discursiva de la “clase media” en Las Mañaneras de López Obrador, cómo AMLO usa el resentimiento social para atacar a sus críticos y cuáles son los principales elementos retóricos empleados contra la clase media. Los resultados finales mostrarán la capacidad de los gobiernos populistas de utilizar estereotipos tradicionales, el resentimiento colectivo y una interpretación parcial de la historia nacional para acosar a los disidentes y lograr altos niveles de aprobación pública.

Published: July 2022

Los conceptos de relevancia y engagement aportan claves para analizar la situación actual de las empresas periodísticas, en busca de un nuevo modelo de sostenibilidad que complemente los ingresos por publicidad, principalmente, con las suscripciones. Para asegurar sus fuentes de financiación, los medios necesitan recuperar la relevancia que han ido perdiendo, y conseguir el engagement con su público. En este trabajo se presentan los resultados de una scoping review cuyo objetivo es identificar la visión de la academia sobre los conceptos de la relevancia y el engagement aplicados a la sostenibilidad del periodismo. Los resultados evidencian una preocupación creciente por la viabilidad económica de los medios. También reciben una especial atención los procesos de innovación y los intentos de afianzar el modelo de negocio en los usuarios de pago. El análisis del engagement muestra que todavía no hay una definición consensuada por parte de la academia. Además, los resultados evidencian diferencias importantes con la visión de los profesionales. La relevancia, aunque en menor medida, está presente en el debate sobre la sostenibilidad a través de la visibilidad y la confianza que aportan las marcas de los medios.

The aim – сhronic heart failure (CHF) is associated with endothelial dysfunction. The pivotal role of nitric oxide in the maintenance of endothelial function (EF) is well-known. But it is unknown whether endothelial nitric oxide synthase (eNOS) gene polymorphismis associated with both EF and clinical outcomes in systolic CHF.Materials and methods. 116 stable (NYHA II–III) ischemic CHF patients with left ventricular ejection fraction (LVEF) ≤ 45 % were examined. Flow-mediated vasodilation (FMVD) of a. brachialis was carried out by standard cuff test. Patients were followed-up for a median of twenty months to determine long-term outcomes. The frequency of T(–786)C genotypes was: TT – 40.5 % (n=47), TC – 43.1 % (n=50), CC – 16.4 % (n=19); the frequency of G894T genotypes was: GG 56.0 % (n=65), GT 33.6 % (n=39), ТТ 10.4 % (n=12). Results and discussion. FMVD in patients with TT genotype of T(–786)C polymorphisms was 7.2 [4.7; 8.3] %, in patients with TC – 6.6 [4.4; 9.1] %, where as FMVD in patients with genotype CC was 4.7 [2.8; 6.0] %, p=0.034 for TT vs. CC; p=0.046 for TC vs. CC. FMVD in patients with GG genotype of G894T polymorphisms was 7.1 [4.3; 9.4] %, in patients with GT – 6.2 [5.1; 8.1] %, in patients with genotype TT was 4.2 [2.5; 5.3] %. The difference between FMVD was significant only TT vs. CC – p=0.030. The patients with CC genotype demonstrated a significantly higher heart failure hospitalization rate (log-rank 5.304, p=0.021) and higher cardiovascular (CV) mortality rate (log-rank 4.011, p=0.045) as compared with the TT homozygote group. LVEF, FMVD, and CC genotype were the predictors of CV mortality in univariate Cox regression analysis, and only LVEF and FMVD in multivariate Cox model. Long-term outcomes were similar in patients with GG, GT and TT genotypes of G894T polymorphisms.Conclusion. In stable ischemic systolic CHF CC T(–786)C eNOS genotype is associated with worse FMVD response and worse long-term outcome versus TT T(–786)C eNOS genotype. TT G(984)T eNOS genotype is associated with worse FMVD response only, but not with long-term outcomes versus GG G(894)T eNOS genotype.

Reference crop evapotranspiration (ETO) is an important hydro-meteorological phenomenon, which is influenced by changing climate. This study estimated the trends ETO and identified the correlation of changes in ETO with climatic parameters in Khulna and Rajshahi districts of Bangladesh. Daily observed climatic parameters of thirty years (1984– 2013) were used in CropWat model to estimate changes in monthly and seasonal ETO. Trend analysis of ETO and climatic parameters were done by Mann-Kendall test and Sen’s slope estimation. Correlation between ETO and climatic parameters were analyzed. The results showed a decreasing trend of ETO over most of the period of the year in Khulna and Rajshahi districts. On monthly basis estimation, decreasing trends of relative humidity, wind speed and sun shine hours in Khulna district, and decreasing trends of wind speed and sun shine hours in Rajshahi district played the dominant roles for the decreasing rate of ETO under recent climate change. On seasonal basis estimation, decreasing trends of relative humidity, wind speed and sun shine hours in Khulna district, and decreasing trends of wind speed and sun shine hours in Rajshahi district played the dominant roles for the decreasing rate of ETO under changing climatic condition. Changes in ETO were most strongly correlated with sun shine hours and most weakly with minimum temperature for both Khulna and Rajshahi. Wind speed was most strongly correlated with ETO for Dry/Rabi season. The findings of this study would be useful for agricultural water management of Bangladesh.

Published: July 2022

The objectives of this study was to investigate the effect of green light-emitting diodes (LEDs) on rice (Oryza sativa L.) seed germination as well as seedling growth. The rice seed of BRRIdhan52, BRRIdhan81, BRRIdhan86 and BRRIdhan92 were germinated and nursed in control environment in full dark (no supplemental light) and under green light (6 h/day with18 h dark). The results showed that germination percent, leaf length, leaf blade length, seedling fresh and dry weight were enhanced by green lighting. Highest germination percent (88%) was counted in BRRIdhan86 and longest first leaf (7.24 cm) with widest leaf (7.24 cm) in BRRIdhan92 under green light. Green light not only enhance the first leaf blade length also increased the dry matter production. High positive significant correlation were observed in seedling fresh weight and dry weight. Correlation value (r) was positive and significantly ranged from 0.999 to 0.981. Green light remarkably promote the leaf surface area, root morphology which ultimately contributed to vigorous seedling growth with an increase 6 to 156 times than rice seedlings grown in dark for the studied character. As a result, the effects of green light emitting diodes (LEDs) on rice seed and seedlings for plant cultivation under controlled-environment conditions are promising, and they may affect subsequent phases of growth and development. More research on green light and other solid state light sources are needed for use in plant lighting designs, as well as the ability to match wavelengths to plant photo sensors for better production and influence on plant morphology and metabolism.
