The article deals with the essence of the national economy competitiveness concept, as well as factors influencing its level, among which an important place is occupied by energy efficiency of the state. Theoretical aspects of the smart grids development are considered, the expediency of their implementation in the context of the national economy competitiveness level increasing is established. A study by reports from the European Commission and the United Nations Economic Commission for Europe has shown that the introduction and deployment of smart grids is one of the priority thematic areas in the implementation of the Trans-European Energy Networks concept. Their use will help to integrate renewable energy sources, optimize the energy market and increase the level of self-regulation of energy use by consumers, as well as to implement the main directions of sustainable development, which today has become an urgent requirement around the world. The ability of smart grids to generate supply and demand information is analyzed, which is important for the integration of an increasing number of renewable energy sources, such as solar and wind energy, while maintaining the stability and efficiency of the energy system. To ensure the effective operation of the network, it is necessary to form a vision and organize the further deployment of technology platforms, as well as to integrate intelligent network applications that will support this vision. The article also examines the functional characteristics of smart grids, the benefits of their use, as well as the main issues related to their use. It is established that the main shortcomings of the smart grids introduction are insufficient confidentiality of customers and the level of information security, as well as network instability and lack of flexibility. The functions of smart grids are grouped according to separate paragraphs, their significance for consumers, investors, environment and competitiveness of the national economy is analyzed. In particular, it is determined that they are more intelligent, decentralized and sustainable than modern networks, and their use will improve the economic efficiency, investment attractiveness and sustainable development.

Published: July 2022

We report on the synthesis and characterization of new ruthenium indenylidene complexes bearing two unsymmetrical N-heterocyclic carbene (NHC) ligands denoted as RuCl2(3-phenyl-1-indenylidene)bis(1-mesityl-3-R-4,5-dihydroimidazole-2-ylidene) in which R is methyl 7a and cyclohexyl 7b. Complexes 7a and 7b were analyzed using single-crystal X-ray diffraction analysis, elemental analysis, IR, NMR spectroscopy, and HRMS. The catalytic activities of complexes 7a and 7b were evaluated in olefin metathesis reactions: ring-opening metathesis polymerization (ROMP) of cis,cis-1,5-cyclooctadiene (COD) and ringclosing metathesis (RCM) of diethyl diallyl malonate (DEDAM) as well as in the isomerization of allylic alcohols. Complexes 7a and 7b failed to initiate the reactions at room temperature in all tested reactions, which might be due to the high thermal stability and low degree of lability of the Ru-CNHC bonds. At 80 °C, the complex 7a showed the best performance due to an increased initiation and a decreased steric obstruction towards the incoming substrates.

Published: July 2022

Extraction is a versatile and relatively simple method for extracting rare and scattered elements, producing good results at minimal expenses in terms of reagents and equipment. Information about the thermal effects and kinetic dependencies of the extraction process is essential for predicting and counteracting fluctuations in external conditions. In this work, the thermodynamic and kinetic parameters of the iodine extraction process were studied using model solutions that contained sodium chloride with an ionic strength of 0–5 mol/l as a background mineralization. This composition closely corresponds to natural and man-made waters of oil and gas condensate fields. A mixture of tri-n-butyl phosphate and isooctane was used as the extractant. In order to evaluate thermodynamic parameters, extraction isotherms were constructed at temperatures of 278 and 288 K. For different background ionic strength values, equilibrium extraction parameters were determined, including the extraction degree, distribution coefficient and equilibrium constant, as well as changes in the enthalpy, entropy and Gibbs energy of the process. A study of the kinetic dependencies of iodine extraction from aqueous solutions under different ionic strength values at temperatures of 278, 288 and 293 K allowed the true and apparent orders of reaction to be established, along with the activation energy of the extraction process. Across the entire range of the studied ionic strength values, iodine extraction occurs spontaneously with high distribution coefficients and an extraction degree of over 86%. The kinetic parameters of the iodine extraction process (activation energy, temporal and concentration reaction order) indicate the diffusion nature of the rate-determining step, the presence of intermediate complexation stages and the absence of temperature effects on the reaction rate.

Published: July 2022

In conformity with a constant tightening of environmental requirements, sulfur compounds are removed from the composition of diesel fuel using the hydrotreating method. However, this has led to a significant deterioration in the anti-wear properties of diesel fuel. To restore the lubricity, oxygen-containing compounds are added to diesel fuel, including carboxylic acids and their amide derivatives, as well as esters, polyamines and other organic compounds. The recommended concentration of the additive, which ranges from 0.015 to 1.0 wt %, is dependent on its specific properties. In addition to anti-wear additives, cetaneenhancing, depressant-dispersing and other additives are added to diesel fuel to correct the properties of the fuel. A method for producing an esterification product for improving the properties of diesel fuel is described. It is shown that an esterification product containing up to 65% fatty acid esters can be obtained at a temperature of 110–115 °С and a process duration of 120–240 minutes when using 3–5 wt % ion-exchange resins for fatty acids. The effect of the additive content on the lubricating properties of diesel fuel is investigated. When 0.5 wt % or more is added, the corrected wear spot diameter is reduced from 615 to 420 µm; when 1.5 wt % is added, it is further reduced to 230 µm. The addition of esterification product to the diesel fuel is shown to result in an increase in the cetane number of initial fuel. When adding 6.0 wt % of the esterification product under development, the cetane number of the fuel is increased from the original 43.0 units to 51.6. In this case, the esterification product can be used as a component for preparing a mixture of biodiesel fuel B6-B20, according to GOST 33131-2014.
Efficiency of dusted gas cleaning using a slotted filter
Authors: Samokhvalov N. M. , Vinogradov V. V.
Published: July 2022

The cleaning of industrial gases from dust is one of the most significant current environmental protection problems. The search for new, more advanced and effective ways to clean dust gases and dust collector designs is based on the diversity of technological conditions for dust formation, the physicochemical properties of gases and trapped particles, and an increase in technical and economic requirements for cleaning processes. When cleaning hot or chemically aggressive gases and capturing abrasive dust, the use of electrostatic precipitators, bag, fibrous and granular filters is often associated with difficulties in protecting the devices from harmful factors or ensuring sufficient cleaning efficiency. The design features of slotted filters permit their use in solving such problems. An engineering method for calculating slotted filters developed on the basis of theoretical ideas and experimental studies is used to model and design slotted filters with specified performance indicators to ensure high cleaning efficiency and low hydraulic resistance. This technique is based on theoretical patterns of filtration using basic dust particle deposition mechanisms on isolated cylinders in relation to the stationary stage of the filtration process. A computer program that simulates the process of cleaning dusty gases in slotted filters has been developed. This makes it possible to determine the optimal operating parameters, design dimensions and regeneration conditions of slotted filters based on a specified cleaning efficiency and hydraulic resistance, taking into account the properties of dust and gas during prolonged continuous operation of the filter.

Introduction: Coronary artery disease (CAD) is the leading cause of heart failure (HF). Only viable dysfunctional myocardium (hibernation) is potentially recoverable with restoration of adequate perfusion. Cardiac imaging modalities have emerged with the ability to differentiate between myocardial scar and viable myocardium and are now often used to direct therapy decisions including revascularization. Decrease in wall motion score (WMS) and improvement in LV ejection fraction (LVEF) during DSE is considered as a surrogate marker for viability of myocardium. It is largely unknown how cardiac specific biomarkers are released in relation the presence and extent of hibernation in patients with ischemic HF. The objectives of this study are to assess the relationship and interaction of the biomarkers BNP and hs TnI with hibernation in patients with chronic ischemic HF. Materials and methods: It is a single center observational study which is conducted in Department of Cardiology, S.M.S. Medical College, Jaipur. 70 eligible patients with suspected ischemic cardiomyopathy (ICMP) are prospectively recruited into an imaging study using DSE to determine viability of myocardium. The patients also had blood sampling at baseline to determine biomarkers. Results: Mean age (in yrs) of patients is 63.78 Â± 10.69 years. No patient is in NYHA I. 25.7 % of patients are in NYHA II (18 patients); 36 patients (51.4%) are in NYHA III and 16 patients (22.8%) are in NYHA IV. On comparison of baseline characteristics among patients with different NYHA class, there is a progressive increase in level of cardiac biomarkers with increase in NYHA class. Both BNP and hs TnI levels are significantly elevated in patients with Improvement in EF >10% as compared with Improvement in EF <10% There is a continuous relationship between increasing degrees of hibernation and increasing BNP and hs Trop I levels. HsTrop I had predicted a positive 56.6% change in Improvement in LVEF. HsTrop I had predicted a positive 52.5% change in decrease in WMS. Conclusion: The current study support the novel concept that the extent of LV hibernation are determinant of serum BNP and hs Trop I elevation in patients with ischemic HF and hs Trop I levels in patients with ischemic HF relate to the degree of hibernation.

Aim: To evaluate any adverse perinatal outcomes associated with abnormal coiling of umbilical cord. Introduction:The primary objective of antenatal and intrapartum fetal surveillance both in early and late pregnancy is to prevent fetal death. One of the most important parts of the fetoplacental unit is the umbilical cord. It is now being studied in predicting the perinatal outcome. Materials and methods: This prospective study was conducted in Obstetrics and gynaecology department of a tertiary care hospital in Smt. Kashibai navale medical college and general hospital Narhe, Pune.Three hundred and fifty (350) umbilical cords of babies delivered either by vaginally or by lower segment caesarian section were examined. The umbilical coiling index was calculated by dividing the total number of coils by the length of the cord in cms. Subjects with umbilical coiling index below 10th percentile, between 10th and 90th percentile and above 90th percentile were defined as hypocoiled, normocoiled and hypercoiled respectively. It was then correlated with the following pregnancy outcomes: mode of delivery, preterm delivery, birth weight, meconium staining, Apgar score at 1 and 5 minutes, and neonatal intensive care unit (NICU) admissions. Hypocoiled cords were those having umbilical cord coiling index (UCI) less than 10th percentile and hypercoiled cords were those having UCI >90th percentile Statistical analysis was done . The results were statistically analysed by chi-square test. The p value â‰¤ 0.05 was considered statistically significant for all the analyses. Result: The mean UCI was 0.61 Â± 0.16. The hypocoiled umbilical cords (UCI < 10th percentile) were significantly associated with low birth weight, meconium staining, low Apgar score at 1 minute, and increased NICU admissions with a p-value < 0.05. Conclusion:Abnormall UCI(hypocoiling) are significantly associated with adverse perinatal outcome.

Published: July 2022

This study aims to analyze Tetragonisca angustula honey from southwestern Bahia for its physicochemical characteristics, phenolic compounds and glioma cell inhibitory effect, in samples from different periods of the year, dry (DP) and rainy (RP) period. The analyses showed that samples obtained in the DP and RP are statistically different for the physicochemical profile (p < 0.05). DP honey has a darker color, greater acidity, content of reducing sugars and ash and lower moisture, when compared to RP. The content of total phenolics and flavonoids was determined spectrometrically, using the Folin-Ciocalteu method and reaction with aluminum chloride, respectively, and there was no statistical difference between the samples (p > 0.05). For the extraction of phenolic compounds, dispersive liquid-liquid microextraction was used, besides analysis by high-performance liquid chromatography with ultraviolet detection (HPLC-UV), which identified chlorogenic acid and quantified caffeic acid and rutin (1.7723 and 0.9384 μg 100 mg-1 honey, respectively). Glioma cell inhibition effect lines were observed for DP at concentrations 1000 ng mL-1 of honey. Principal component analysis (PCA) proposes the physicochemical parameters as the main distinguishing factors between the DP and RP samples. DP samples showed similarity for the parameters ash content, acidity and reducing sugars and the samples of the RP had consonance between pH and moisture.
Public-Private Partnership in the Russian Education System: Advantages, Problems, and Directions of Development
Authors: Shor Inna
Published: July 2022

The present article describes the advantages, current problems, and development directions of public-private partnership in the Russian education system. Sustainable development requires inclusive, affordable, and high-quality education. Statistical data demonstrated a significant state underfunding of the Russian education system and, as a result, the poor technical state of education facilities in the country. Therefore, public-private partnership can serve as a way to attract financial resources and competences of private partners to the education system. The paper focuses on such issues as the advantages of public-private partnership in the education system, the needs of the main stakeholders of public-private partnership projects, socio-economic effects of public-private partnership, etc. Based on various financial, economic, legal, and managerial issues, the author gives practical recommendations, e.g., state assistance at the local level, universal box solutions for standard education facilities, a new legitimate tool for changing public-private partnership projects, etc. The problem needs a systematic approach. The study relied on the general scientific method of dialectical cognition of economic and financial phenomena, as well as analysis, synthesis, and expert evaluation. The systematic approach can facilitate managerial decisions in the sphere of education and public-private partnership.

Published: July 2022

Este artigo tem como objetivo investigar o conceito de experiência na filosofia de Dewey e Gadamer, bem como suas implicações para a formação. Sendo assim, a questão que nos move é: quais os efeitos da experiência no processo de formação? Atualmente, muito se fala sobre experiência e formação, e advém desse contexto a necessidade de tecermos um olhar cuidadoso acerca das nuances que estão compondo esses conceitos, sobretudo no campo da Educação. Para isso, desenvolvemos um estudo de natureza qualitativa, que tem como aporte metodológico a pesquisa bibliográfica. Neste prisma, ao buscarmos criar um mapa teórico visitando tradições distintas, compomos o referencial que embasa esta pesquisa, instrumentalizando-nos com a leitura de: Gallo, Heidegger, Hermann, Kneller, Kuhn, Trevisan e, principalmente, Dewey e Gadamer. Dessa forma, apresentamos como resultado a compreensão de que, seja um acontecimento extraordinário ou algo simples, experiência é tudo aquilo que altera o modo de pensar e/ou agir do sujeito, passando a constituí-lo de modo diferente, portanto, a formá-lo.

O objetivo do estudo foi investigar o conhecimento de professores da Rede Municipal de Ensino do Recife sobre a relação das habilidades auditivas e linguísticas com a aprendizagem, sobre a fonoaudiologia educacional e o perfil de formação dos professores dos primeiros anos da escolarização básica do Brasil. Trata-se de um estudo exploratório quantitativo e qualitativo, realizado com 488 professores que lecionam na rede pública de ensino do município de Recife/PE/Brasil. Os dados foram recolhidos por meio de um questionário estruturado, aplicado durante encontros mensais de formação continuada para professores. Os resultados revelaram que os professores reconhecem, de um modo geral, a importância da audição e da linguagem para a aprendizagem, embora não se sintam preparados para lidar com isso na escola e, como esperado, não possuem conhecimentos mais específicos sobre o processamento auditivo. Consequentemente, os encaminhamentos para especialistas da saúde são frequentes diante dos problemas de aprendizagem, desconsiderando as habilidades auditivas. Conclui-se que os professores reconhecem a importância do tema abordado; contudo, demonstram não ter domínio sobre a relevância das habilidades auditivas e linguísticas para a aprendizagem e para o desenvolvimento do estudante, bem como conhecimentos sobre o papel do fonoaudiólogo no âmbito escolar.

Published: July 2022

Assumida como um recurso estratégico para a economia e sociedade do conhecimento, a educação doutoral tem-se tornado alvo de atenção e intervenção política, com efeitos visíveis na sua organização e oferta. Sob a influência de diversos atores, e especialmente na Europa, a educação doutoral tem-se expandido, quer em termos do número de universidades que a ofertam, quer no tocante ao número de programas; tornou-se mais diversificada, com programas doutorais nas mais diferentes áreas científicas e com diferentes tipos e propósitos; e tornou-se mais estruturada, com a inclusão de uma componente curricular e a redução do tempo para conclusão do grau. Muitas destas tendências de mudança são evidentes nas configurações assumidas pelo ensino doutoral em Portugal. Este artigo tem como objetivo contribuir para uma melhor compreensão dessas configurações, por meio do mapeamento do cenário atual da educação doutoral no país. A análise leva em consideração aspetos como a distribuição institucional, geográfica e científica dos programas doutorais, bem como a sua caraterização em termos de estruturação, duração e colaboração interinstitucional. Por último, as tendências observadas no cenário da educação doutoral são colocadas em perspetiva e apresentam-se recomendações com vistas à sua (re)organização, tendo como alvo os legisladores e as universidades.

Este artigo tem como propósito levantar debates mobilizando a mancala como prática social e não como um jogo, no sentido de decolonizar concepções extrativistas do conhecimento africano que têm sido geradas pelo uso da epistemologia eurocêntrica como padrão de correção de todas as práticas do mundo. Deste modo, propomos olhar para a mancala como um tipo de jogo de linguagem nos aproximando da filosofia do segundo Ludwig Wittgenstein, isto é, como parte de um exercício terapêutico-gramatical-decolonial de modo a construir outros “mundos possíveis”, formas outras de educar em diálogos afrodiaspóricos, que possibilitem tensionarmos a imposição do olhar eurocêntrico sobre as práticas africanas. Para isto, partimos da compreensão de que há conhecimentos matemáticos que se manifestam de diferentes maneiras em todas as culturas e da importância do desprendimento epistemológico para possibilitar diálogos entre formas de vida.
Perspectiva histórica y emocionalidad en la formación del profesorado de Historia portugués y español
Authors: Carril-Merino María Teresa , Santos Solé Maria Glória Parra , Sánchez-Agustí María
Published: July 2022

En este artículo se presentan los resultados de un estudio que tiene como finalidad evaluar la capacidad de adoptar perspectiva histórica por parte de futuros profesores de Historia de Educación Secundaria, portugueses y españoles. Para ello, se utiliza una muestra de dos grupos equiparables, constituidos por 52 alumnos de la Universidad de Valladolid (España) y 42 alumnos de la Universidade do Minho (Portugal). El estudio se desarrolla en paralelo en los dos grupos y utiliza como estrategia una actividad de contrariedad sobre el trabajo infantil en la minería del siglo XIX, donde la emocionalidad está fuertemente implicada. Metodológicamente, esta investigación se plantea desde el paradigma cualitativo mediante la interpretación de las narrativas de los informantes y su sistematización en función de cuatro categorías progresivas, que van desde una adopción de perspectiva condicionada por el presente hasta una comprensión histórica ambientada en las condiciones de vida proletarias. Por último, se exploran las diferencias de perspectiva histórica, si las hubiera, en función de la variable independiente del género. Los resultados de la investigación muestran que, en ambos colectivos universitarios, la mayor parte de los estudiantes de Máster se agrupan en los niveles intermedios de empatía histórica y solo un pequeño grupo de los profesores de Historia en formación realiza explicaciones plenamente contextualizadas. En consecuencia, se puede considerar que el factor emocional, cuando vulnera el marco de valores de la sociedad actual, aleja a la muestra de los patrones de la época y no favorece la comprensión compleja del contexto histórico.

Sistem pembelajaran jarak jauh pada PAUD (Pendidikan Anak Usia Dini) tergolong baru dan belum banyak penelitian yang meneliti pengaruhnya terhadap pencapaian tumbuh kembang anak usia dini terutama yang berkaitan dengan karakter resiliensi. Rencana Program Pembelajaran Mingguan (RPPM) yang disusun oleh pendidik merupakan jembatan dalam inovasi pendidik PAUD dalam pembentukan karakter tangguh. Arahan yang ditulis oleh pendidik dalam RPPM sangat membantu orang tua dalam mendampingi anak belajar di rumah. Tujuan penelitian ini adalah untuk mengukur tingkat pemahaman guru PAUD dalam menyusun RPPM selama pelaksanaan BDR (Belajar dari Rumah) yang memiliki muatan resiliensi. Penelitian ini menggunakan pendekatan deskriptif kuantitatif dengan teknik pengumpulan data menggunakan kuesioner. Hasil penelitian ini memberikan gambaran terkini bahwa pendidik PAUD di Kecamatan Depok telah menerapkannya melalui Rencana Pelaksanaan Pembelajaran Mingguan (RPPM) bagi orang tua yang mengandung sikap resiliensi seperti konsep diri positif (84,8%), mampu mengontrol diri sendiri (91,7%), pantang menyerah, ingin terus belajar (51,7%), optimis (90,3%). Stimulasi sikap optimis, menduduki peringkat tertinggi yang telah terstimulasi dengan baik, sedangkan kemampuan menumbuhkan semangat belajar terus menerus menempati persentase paling rendah salah satunya dikarenakan kebosanan anak dalam mengikuti kegiatan pembelajaran online yang memiliki ritme hampir sama di masa pandemi ini. Saat ini pendidik PAUD mendambakan untuk kembali bertatap muka dengan anak.

The government of Malaysia is committed and receptive to environment conservation efforts. The study's explicit goals will now be as follows: a) Determine community participation techniques in environmental conservation programmes; b) Detect concerns and hindrances to community participation in environmental conservation programmes; and c) Suggest the most effectual community participation approaches in environmental conservation programmes. We spoke to eight main informants from three tiers of local governments. The observations were organised using NVivo. Community participation is hampered by a lack of enthusiasm and understanding, as well as a lack of workforce and finance. 9AN

területfejlesztés geopolitikai-geoökonómiai jelentősége
Authors: Tőkés Tibor
Published: July 2022

A területfejlesztés mint tevékenység a történelem folyamán összekapcsolódott az állammal, és az folyamatosan jelen van a gazdaság és a társadalom életében. Egy ország gazdasági teljesítménye, gazdasági stabilitása determinálja annak geopolitikai szerepét és jelentőségét. A 21. század első évtizedében az államok közötti konfliktusok rendezésére alkalmazható eszközök átalakultak, az egyes országok gazdasága lett az a fegyvertár, mely segítségével az államok az új típusú, hagyományos erőszaktól mentes háborúikat, azaz a „gazdasági háborúkat” vívhatják. Ennek következtében a területfejlesztés eszközrendszerével is kibővült a fegyvertár, így e tevékenységnek kétségkívül van geopolitikai és geoökonómiai vonatkozása is. A tanulmány ezeket a területfejlesztés, a geopolitika és a geoökonómia közötti összefüggéseket igyekszik vizsgálni. JEL kódok: F59, O29
Corporate tax - a new paradigm is needed! -II. A new global value-added tax is needed instead of a corporate tax
Authors: Török László
Published: July 2022

Abstract: The corporate tax system is easy to manipulate in modern economies, with high explicit and implicit costs of maintaining it. Attempts to reform it have been unsuccessful, with aggressive tax planning and tax evasion gaining ground at the international level. The source of constant conflicts between national tax administrations and companies is also the corporate tax base and tax accounting. Therefore, based on a new paradigm, I have developed a new, globally introduce, corporate value-added tax on corporate adjusted sales. Revenues from this tax would replace general government revenues lost due to the abolition of corporate tax. Based on the GDP of the member states of the European Union, I calculated the rate of the new tax for all member states. In the study, I present in detail, the mechanism of operation of the new tax, then describe the advantages of the introduction of the new tax compared to the corporate tax. Finally, I will thoroughly present how the taxation of dividends from company owners/shareholders would change if the new tax I planned was introduced and operated. This new type of taxation of dividends would, in my view, contribute more fairly to the burden-sharing.
