Class IC Antiarrhythmic Drugs: Informed Choice
Authors: Sydorova Nataliia
Published: May 2023

The article presents data on the most commonly used antiarrhythmic drugs of subclass IC: propafenone, flecainide, and a drug manufactured in Latvia — ethacizine. The features and priority areas of each drug use were identified. The author conducted a critical analysis of the results of Cardiac Arrhythmia Suppression Trials (CAST)-I and CAST-II and suggested ways to further study of subclass IC antiarrhythmic drugs in the context of current treatment strategies. The results of CAST-I and CAST-II should be interpreted in view of the heterogeneity of the subclass IC antiarrhythmic drugs and the fact that among the drugs of this subclass that are currently registered and approved for use in Ukraine, only flecainide was studied in CAST-I, and none of these drugs — in CAST-II. Ethacizine has a special position as a promising drug, especially effective in the treatment of vagus-induced heart rhythm disorders, with a small number of contraindications and drug interactions compared with propafenone and flecainide. Despite many years of use in several countries, this drug remains “invisible” to researchers around the world due to a limited number of international studies. The author draws attention to the need to re-evaluate antiarrhythmic drugs with an outdated evidence, in some cases quite limited, and to plan new experimental studies to clarify the possibility of subclass IC drugs to influence new pharmacological targets in arrhythmology, as well as large-scale well-planned studies of the safety and efficacy of subclass IC antiarrhythmic drugs in real present-day clinical practice.

Published: May 2023

Background

In most term neonates, the ductus arteriosus closes functionally on the first day of life, and a permanently open ductus arteriosus is abnormal.

Objectives

To evaluate the effect of oral acetaminophen on patent arterial duct (PDA) closure in premature infants less than 32 weeks.

Methods

This randomized clinical trial was performed on 140 preterm neonates with gestational age less than 32 weeks and birth weight less than 1,500 g, admitted to the neonatal intensive care unit of Ali Enbe Abitalib Hospital in Zahedan between 2019 and 2021. The neonates were randomly divided into two groups, with and without acetaminophen administration. In the intervention group, acetaminophen drops were started during the first 24 hours after birth and were administered for five days. In both groups, echocardiography was performed five days after birth. Finally, the data were analyzed in SPSS software.

Results

About 140 neonates with gestational age of ≤32 weeks and weight at birth ≤1,500 g were admitted for the study. The neonates were equally divided into two groups and acetaminophen medication assigned for one of the groups. Of the 70 neonates who did not receive acetaminophen administration, 75.7% had PDA closure spontaneously; this pattern was 94.3% in patients who had treatment with acetaminophen. This effect of treatment was significant (X2=9.468, p=0.002).

Conclusion

The study showed significant improvement in PDA in neonates receiving paracetamol. This can have a significant impact on the treatment approach to preterm neonates.

Published: May 2023

Background
Technitium-99m (99mTc) is a widely used radioisotope for the diagnostic procedures in nuclear medicine. The radioisotope is eluted from 99Mo/99mTc generator. Ideally there should be no Molybdenum-99 (99Mo) or any other contamination; however, sometimes traces of 99Mo are co-eluted from the generator. This impurity interferes labeling of 99mTc with pharmaceuticals result in poor quality radiopharmaceutical and unnecessary exposure to patients. The purpose of this study is to assess the contamination level of 99Mo in the eluted activity of 99mTc used for the diagnostic procedures at Swat Institute of Nuclear Medicine, Oncology and Radiotherapy (SINOR), Swat Pakistan. Also the purpose is to check the integrity of the generators being transported by road, and it is a part of quality audit of PAKGEN 99Mo/99mTc generators.
Methods
The data was collected for 166-PAKGEN 99Mo/99mTc generators used over 6 years at SINOR. The generators were procured from Isotope Production Division (IPD), Pakistan Institute of Nuclear Science and Technology (PINSTECH), Islamabad, Pakistan. The 99Mo impurity concentration was measured for each elution with dose calibrator (Capintech Inc. CRC-25R) and canister.
Results
Results for most of the generators (99.4%) were within the permissible limit (0.15 μCi of 99Mo/mCi of 99mTc) as per Pakistan Nuclear Regulatory Authority (PNRA), Nuclear Regulatory Commission (NRC), and other regulatory authorities. Only one generator (0.6%) had the values out of range.
Conclusion
99Mo breakthrough concentration for most of the generators was within permissible range which shows integrity of 99Mo/99mTc PAKGEN generators and approves the quality of locally prepared 99Mo/99mTc PAKGEN generators. The study replicates excellent manufacturing and quality control of PAKGEN generators which offers a confirmation of safe medical practices.

Base Nacional Comum Curricular e Língua Portuguesa: ecos dos multiletramentos
Authors: Sousa Silva Shirley Adriana
Published: May 2023

Com o surgimento de novas tecnologias da comunicação, o conceito de letramento tem sido, constantemente, repensado, para englobar uma variedade de modos de significação dos mais locais aos mais globais, distanciando-se, progressivamente, de uma noção do letramento puramente verbal escrito.  Isso porque o mundo, hoje, demanda mais que letramento escrito. Antes, requer pessoas mais integradas ao design multissemiótico dos textos, que transponham o foco circunscrito à escrita como modalidade principal de veiculação de significados, que assumam outras tecnologias nas quais a sobreposição de modalidades oral, escrita, gestual, tátil, espacial e visual está presente. Assim, o presente trabalho se deve à crescente necessidade que o atual contexto sociocultural impõe aos profissionais da educação, de modo geral, e, mais especificamente, aos professores de Língua Portuguesa, sobre a necessidade de os estudantes se apropriarem da diversidade de linguagens, culturas e mídias que direcionam aos multiletramentos (ROJO, 2012). Em face disso, este estudo analisa as habilidades indicadas na Base Nacional Comum Curricular para o Ensino Novo Médio, componente Língua Portuguesa (BRASIL, 2018), a fim de identificar as características dos multiletramentos em sua articulação.

Published: May 2023

Предложена стратегия построения обучающего набора данных для подавляющей численную дисперсию нейронной сети NDM-net (numerical dispersion mitigation network), заключающаяся в расчете полного набора сейсмограмм методом конечных разностей на грубой сетке и в расчете обучающей выборки с применением более мелкой сетки. Обучающая выборка представляет собой малый набор сейсмограмм с определенным пространственным размещением источников волнового поля. После обучения сеть NDM-net позволяет аппроксимировать низкокачественные сейсмограммы, рассчитанные на грубой сетке, в сейсмограммы с меньшим шагом дискретизации. Оптимизация процесса построения репрезентативной обучающей выборки сейсмограмм основана на минимизации метрики Хаусдорфа между обучающей выборкой и полным набором сейсмограмм. Применение нейронной сети NDM-net позволяет уменьшить временные затраты при расчетах волновых полей на мелкой сетке.

The article outlines a strategy for constructing a training data set for a numerical dispersion mitigation network (NDM-net), consisting in the calculation of the full set of seismograms by the finite difference method on a coarse grid and the calculation of the training sample using a fine grid. The training dataset is a small set of seismograms with a certain spatial distribution of wave field sources. After training, the NDM-net allows approximating low-quality coarse-grid seismograms into seismograms with a smaller sampling step. Optimization of the process of constructing a representative training dataset of seismograms is based on minimizing the Hausdorff metric between the training sample and the full set of seismograms. The use of the NDM-net makes it possible to reduce time costs when calculating wave fields on a fine grid.

Authors:   Department of Pharmacology, L M College of Pharmacy, Ahmedabad, Gujarat, India, Dodiya Hardik G
Published: May 2023

Numerous clinical studies reported effectiveness of add-on non-steroidal anti-inflammatory agents in patients with depression. In the present study, we investigated efficacy and safety of add-on aceclofenac alone or in-combination with serratiopeptidase to sertraline in patients with depression. A total of 102 patients with depression were assigned to three different treatment groups: A) add-on aceclofenac monotherapy (200mg/day) to sertraline B) add-on fixeddose combination (FDC) of aceclofenac and serratiopeptidase (200+30mg/ day) to sertraline C) sertraline (150mg/day). Efficacy measures included the HAM-D17 score, MADRS score and biomarkers levels like interleukin-6, cortisol and brain-derived neurotrophic factor (BDNF). Treatment with addon aceclofenac monotherapy or its combination with serratiopeptidase to sertraline showed significant reduction in HAM-D17 score at week 8 and week 12 as compared to sertraline monotherapy. Add-on therapies also showed reduction in MADRS score at week 12. Interleukin-6 levels significantly reduced in patients treated with add-on aceclofenac monotherapy or add-on FDC treatment with that of sertraline monotherapy at week 12. Both add-on treatments to sertraline also showed significant improvement in BDNF levels as compared to sertraline monotherapy at week 12.The antidepressant activity and neuroprotective potential of add-on aceclofenac monotherapy or its combination with serratiopeptidase to sertraline can be attributed to its capability of reducing IL-6 and cortisol levels and augmenting levels of BDNF.

Published: May 2023

AUDs (Alcohol Use Disorders) encompass pathologies with individual traits and manifestations linked to genetic backgrounds, environmental exposures, and family and social dynamics. The search for effective pharmacological treatments has frequently thrown its weight behind a single therapy: a purported “silver bullet” that may cure alcoholism. However, given the complexity of the pathologies associated with AUDs, and the individual variations, this endeavor may fail. Consequently, basic research and clinical trials have contributed strategies targeting specific facets of harmful alcohol consumption.

Influence of near-surface oxide layers on TiFe hydrogenation: mechanistic insights and implications for hydrogen storage applications
Authors: Santhosh Archa , Kang ShinYoung , Keilbart Nathan , Wood Brandon C. , Klassen Thomas , Jerabek Paul , Dornheim Martin
Published: May 2023

The inevitable formation of passivating oxide films on the surface of the TiFe intermetallic compound limits its performance as a stationary hydrogen storage material. Extensive experimental efforts have been dedicated to the activation of TiFe, i.e. oxide layer removal prior to utilization for hydrogen storage. However, development of an efficient activation protocol necessitates a fundamental understanding of the composition and structure of the air-exposed surface and its interaction with hydrogen, which currently is absent. Therefore, in this study we explored the growth and nature of the oxide films on the most exposed TiFe surface (110) in depth using static and dynamic first-principles methods. We identified the lowest energy structures for six oxygen coverages up to approximately 1.12 nm of thickness with a global optimization method and studied the temperature effects and structural evolution of the oxide phases in detail via ab-initio molecular dynamics (AIMD). Based on structural similarity and coordination analysis, motifs for TiO2, TiFeO3 as well as Ti(FeO2)x (x = 2, 3 or 5) phases were identified. On evaluating the interaction of the oxidized surface with hydrogen, a minimal energy barrier of 0.172 eV was predicted for H2 dissociation while the H migration from the top of the oxidized surface to the bulk TiFe was limited by several high-lying energy barriers above 1.4 eV. Our mechanistic insights will prove themselves valuable for informed designs towards new activation methods of TiFe and related systems as hydrogen storage materials.

Published: May 2023

A strategic roadmap for non-carbonized fuels is a global priority, and the reduction of CO2 emissions is a key focus of the Paris Agreement to mitigate the effects of rising temperatures. In this context, hydrogen (H2) is a promising non-carbonized fuel, but the pace of its implementation will depend on the engineering advancements made at each step of its value chain. To accelerate its adoption, various applications of hydrogen across industries, transport, power, and building sectors have been identified, where it can be used as a feedstock, fuel, or energy carrier and storage. However, widespread usage of hydrogen will depend on its political, industrial, and social acceptance. It is essential to carefully assess the hydrogen value chain and compare it with existing solar technologies. The major challenge to widespread adoption of hydrogen is its cost as outlined in the roadmap for hydrogen. It needs to be produced at the levelized cost of hydrogen (LCOH) of less than $2/kg to be competitive with the established process of steam methane reforming. Therefore, this review provides a comprehensive analysis of each step of the hydrogen value chain, outlining both the current challenges and recent advances.

Published: May 2023

Abstract. The article presents the data of experts’ assessments of the impact of the coronavirus pandemic on the world economy; the scenario forecast of deepening global crisis in 2021 and 2022. The IMF predicts a slowdown in 2022 in the global economy, which could cause a financial crisis. UN Secretary-General Antonio Guterres shares the same view. According to his statement, the coronavirus pandemic would lead to the worst crisis in the last century.

Coronavirus has affected education not only in Ukraine, but also in Western countries, where the traditions of higher education are long and well known, and education is very expensive. The pandemic forced distance learning even at world-renowned universities, sparking a wave of protests among students for several reasons. The first is financial. Full-time education is more expensive than distance learning. Due to the transfer of full-time students to distance learning, they began to require university administrations to review pricing policies. The second reason is the decline in the prestige of education compared to previous years. Thirdly, the pandemic will inevitably lead to an unstable labor market for graduates. During this time, Ukrainian education has faced such problems that occur in the best universities in the world.

The global paradigm of higher education is changing rapidly. Short training programs for quick acquisition of new skills come to the fore. Distance learning opens up new perspectives. Anyone can attend lectures from leading universities. The service allows getting a bachelor’s or master’s degree.

The positive experience of Polish education is highlighted in this paper. The deterioration of education as a threat not only to the quality of training of highly qualified specialists, but also to the country as a whole is emphasized. The important role of artificial intelligence in education is pointed out. The initiative of the President of Ukraine V. Zelensky on the need to create a presidential university of modern education and a research center - a leader in strategic areas of state development has been announced.
RISK MANAGEMENT IN THE CONTEXT OF CORPORATE GOVERNANCE: DOMESTIC EXPERIENCE
Authors: Babych Svitlana
Published: May 2023

Abstract. The purpose of this article is to assess the formal manifestations of taking into account the principles of risk management in the domestic corporate governance system. A low or satisfactory tendency of the domestic corporate sector to assimilate the rules of corporate governance abroad may also indicate in advance the lack of active risk management in domestic companies in the context of corporate governance. The survey participants' awareness of the importance of the "Risk Management" function of the supervisory board regarding the state of corporate governance in Ukraine does not automatically guarantee the implementation of this function in practice. The results of the analysis of the reporting of joint-stock companies, whose shares are included in the calculation of the PFTS index, indicate the absence and/or lack of disclosure of information regarding the relationship between risk management and corporate governance at domestic enterprises. The leading role of corporate management bodies, in particular the supervisory board, in the formation of long-term risk management policy, including and corporate. The domestic corporate sector as a whole is characterized by a satisfactory level of corporate governance, which indicates incomplete compliance with the principles of corporate governance developed by the international community. Domestic practitioners of corporate governance have formed the correct attitude in theory to the role of the supervisory board in risk management. In practice, according to the results of the assessment of joint-stock companies included in the calculation of the PFTS index, in the context of corporate risk management, insufficient attention is paid, and the reports are of a formal nature. Strengthening the relationship between corporate governance and risk management is possible provided that measures and disclosure of information are implemented in the following directions: constant monitoring of the risk management system and disclosure of information regarding risk management; identification of significant risks; determination of the risk profile of corporate bodies; remuneration for risk management in the short and long term; principles of risk management; reporting to the board.

Published: May 2023

Abstract. Financial sector organizations with Human Resources division face with change. Competition, globalization, constantly evolves consumer preferences, these factors are challenges for most of financial organizations in Human Resources Management. Combination with traditional business risks and economy lifecycles are the main reason why financial sector institutions are forced to use Lean and Agile Methods. Customer satisfaction and efficiency play an important role in this tough competition in modern business sector. Lean, Agile or Lean Agile strategy aims to achieve long-term objectives such as Human Resources process efficiency and customer satisfaction. The process of worker selection, continuous skill development, improvement, mistake proofing, reconfiguration for new products are discussed from a human-centric factor perspective. Human factor starts to play the main role. It is important to state that correct form of chosen strategy with customer satisfaction achievement have a significant positive influence on Human Resources division in financial sector profitability. Also, it can be considered as an indicator for future profitability and satisfaction index in financial performance. These outcomes are important for both Human Resources managers and decision makers in financial organization. It can be strongly pointed that Human Resources managers and decision makers can take financial institutions e.g. banks level and trend in customer satisfaction to make assumptions on its future efficiency, productivity and marker performance. Companies that adopt Lean and Agile into Human Resources Management give many thoughts to how employees experience the workplace. In some cases, employees are treated as customers. No innovation provides limitation of growth opportunities in financial institutions sector. It is also stated that there is a relationship between customer satisfaction and efficiency in Human Resources in financial organizational with the help of Lean and Agile Methodology.

Published: May 2023

The purpose of this article is to study the state of global convergence of financial reporting standards at the present stage, as well as to consider the key points of the process of unification of International Financial Reporting Standards (IFRS) and Generally Accepted Accounting Principles (GAAP). To achieve this goal, the article considers the concepts of convergence, harmonization and standardization, presents an analysis of the intensity of use of these concepts, which are associated with the dynamic development of recent global accounting transformations and major trends in international convergence of financial reporting. The key stages of the process of unification of International Financial Reporting Standards (IFRS) and Generally Accepted Accounting Principles (GAAP) are considered. For decades, the European Union, the International Organization of Securities Commissions (IOSCO) and the Committee on International Accounting Standards have supported international efforts to harmonize US GAAP and IFRS. accounting and reporting standards used in different countries. We have determined that while both IFRS and GAAP aim to provide transparency, informational content and usability in financial statements, these standards use different approaches to achieve this. We indicated that at present IFRS is the dominant accounting and reporting system, in fact, only third world countries do not apply it. We have proven that in the process of achieving convergence, a single set of understandable and feasible international accounting standards must be developed, requiring high quality, transparent and comparable information in financial statements in order to ensure convergence of IFRS and GAAP. We analyzed the intensity of the use of the concepts of IFRS and GAAP, which are associated precisely with the convergence of these accounting systems using the Google Ngram Viewer (GNV) tool. We have proved that the Convergence of IFRS and GAAP also applies to Ukraine, since the convergence is bilateral, any change in IFRS will ultimately affect the Ukrainian accounting and reporting system.

Published: May 2023

Abstract. The scientific article analyses the approaches of domestic and foreign scientists to determine the essence of the concept of "intellectual migration". We have determined that intellectual migration is equated by scientists with the migration of highly qualified workers with higher education for employment abroad to realize their professional and intellectual abilities on purpose. The authors analyzed the dynamics of the number of issuances and renewals of the EU Blue Card, which confirms the high level of interest of Europeans in the employment of intellectual migrants. In 2019, Ukrainian intellectual migrants owned about 5% of all issued and updated EU Blue Cards. In general, the value of this indicator has increased more than 12 times over the last 9 years. We analyzed vacancies for employment of intellectual migrants from Ukraine in the European Union on the job search site robota.ua during October 2021. The study found that the most popular areas of intellectual labour migration among EU member states were Poland (42%) and Germany (13%). In terms of professional orientation of current vacancies, advertisements for employment of managers with a share of 28% in total prevail. The authors investigated the relationship between the «brain gain» indicator in the Global Talent Competitiveness Index and the country’s economic growth, based on gross domestic income per capita. Based on the calculated value of Pearson’s pairwise correlation coefficient (0.882) on the example of the European Union, we found a significant impact of the level of attractiveness of the tap for intellectual migrants on its economic prosperity. In order to detail this relationship, the authors developed an economic-mathematical model of the form y = 718.77x-5213.7, which proves that with increasing value of the indicator "brain growth" in the Global Index of Talent Competitiveness, GDP per capita increases.

Abstract. The article substantiates socio-economic approaches and the relevance of implementing a knowledge management system at the enterprise. The knowledge of HR managers can be divided into: fundamental, ensuring specialization and success; technological and informational regarding the introduction of innovations. E-knowledge management is an interrelated part of Personnel Management in an enterprise, which shows the ability to produce added value from intangible assets. The main resource areas of the e-knowledge management program are people, processes, technology, structure, and value orientations.

Knowledge management is a subsystem for implementing electronic knowledge management, searching for it, maintaining it, reproducing it, applying automation and storing information about knowledge. Undoubtedly, this is what strengthens the leadership position in the real market segment. The use of e-knowledge management software improves: new employee adaptation, information segmentation by projects, setting benchmarks, enabling dynamic search, developing a content creation platform, improving customer service, and consolidating knowledge over time. The components of the process of creating, identifying, and using electronic knowledge to maintain and achieve a positive result are presented. The main obstacles are the low professionalism of employees and their skills in applying information technology programs to introduce innovations in the field of knowledge management. Calculating the cost of purchasing and implementing “PCRecruiter” software shows the high cost and long-term payback of this project for a medium-sized enterprise with 200 employees. In times of crisis and war, the use of "PCRecruiter" is possible for large enterprises with a high level of income. It is advisable to choose cheaper software packages Galaxy ERP, SAPR/3, OracleAplications.
STATE SUPPORT FOR ENTREPRENEURSHIP DEVELOPMENT IN ITALY
Authors: Sypko Vladyslav
Published: May 2023

Abstract. Entrepreneurship is a very important part of economic development, which is why the level of its efficiency reflects the development of the country as a whole. State support of enterprises of various sizes allows to advance the level of the economy a few steps forward and thus strengthen the economic stability of the country. The article describes the state of Italy’s economic development since the 1950s and the methods by which the state supported and developed entrepreneurship and eventually became one of the world’s most developed leaders. The results of the study showed that after the Second World War, Italy suffered greatly and, in order to boost the economy, used the strategy of developing state-owned enterprises with further liberalization. Since the 2000s, Italy has intensified its policy of non-interference, the main idea of ​​which is the self-balance of the economy as a whole, by introducing relevant legislation. Despite significant progress, problems have arisen in some areas, in particular with small and medium-sized farms, which are very important in the economy. Research has shown that there is almost no state support in this area and it is very difficult for farmers to start their own business. In addition, the situation is similar with young start-ups, their main problem being the lack of funding, which Italy has now partially solved by implementing a microfinance system. I found that the share of small and medium enterprises in Italy is the largest, and they have a strong impact on economic performance, so their support from the state is necessary for their full functioning and maximum efficiency. Also in the article, I assessed the effects of COVID-19 and found that the pandemic hit the economy hard, reducing GDP by 9.5%. Such a sharp decline is also due to the cost of supporting businesses and the public during coronavirus infection. In addition, I described the methods by which the country spreads the interest of ordinary people in business. I also gave examples of Italy’s participation in projects aimed at developing and supporting entrepreneurship and creating certain grants that should help student entrepreneurs who do not have enough investment to start their own business.
CURRENT TRENDS IN THE DEVELOPMENT OF THE BANKING SYSTEM OF UKRAINE

Abstract. The article examines the peculiarities of the banking system of Ukraine and analyzes foreign experience in this area. The results of the study show that the domestic banking system is less capitalized compared to developed countries and has a smaller reserve of liquidity. It was determined that by using advanced global trends in monetary policy and the implementation of banking activity, it is possible to improve its condition.

A study of the state of the banking system of Ukraine in modern conditions was conducted and its key trends were identified. We note the decrease in the number of banks and the decrease in their profitability with the introduction of martial law due to the increase in risks and the deterioration of the socio-economic situation of the country. However, in general, the banking system has withstood the serious challenges of the modern stage: banks operate and lend while maintaining liquidity.

It is justified that in today's conditions, an important task is to support the activities of banking institutions. In order to ensure the smooth operation of banks and the electronic payment system, the NBU took timely steps that allowed this period to pass with moderate losses for the financial sector. Thus, the NBU reduced the requirements for the formation of reserves and refinanced banks in order to increase the liquidity of the banking system of Ukraine.

The government's interest expense compensation programs also have a positive impact on credit recovery and the state of the banking system.

The article formulates the key problems of the banking system of Ukraine and defines the ways of its development, the use of which will contribute to the optimization of its activity and the development of the financial system as a whole.
Luta migrante e comunicação na fronteira Brasil-Venezuela:
Authors: Camargo Julia
Published: May 2023

As fotos apresentadas neste ensaio capturam a medida das coisas urgentes, que abarcam o desejo de se comunicar, de estar conectado, de saber/dar notícias, de enviar/receber recursos, de ter acesso ao lazer, de cumprir burocracias e assim assegurar condições básicas de afetos, direitos e dignidade de vida. As cenas foram observadas no estado brasileiro de Roraima, nas cidades Boa Vista e Pacaraima, nos últimos quatro anos, no âmbito de pesquisas e projetos comunitários sobre comunicação e acesso à conectividade por refugiados, os quais tive oportunidade de participar por meio da Universidade Federal de Roraima (UFRR/Brasil). Para além de cenários de exclusões e desigualdades, características impressas historicamente ao Sul Global, as imagens também revelam espaços sutis de criação e reinvenção de subjetividades, de solidariedade, de produção de brechas em meio a limitações que perpassam as experiências de pessoas que estão se deslocando.

Em uma síntese entre miséria e magia, a comunicação e a conectividade aparecem nas fotografias como lugares estratégicos para observar as disputas de poder, as desigualdades digitais e as táticas que se desenrolam nas dinâmicas migratórias na fronteira entre Brasil e Venezuela. Em tempos nos quais a digitalização da vida vem se tronando cada vez mais premente, pensar a comunicação de forma cidadã e libertadora, promotora de uma coletividade protagonista, conforme propunham Freire[1] (1983) e Kaplun[2] (1985) ainda é uma aposta que segue sobre a mesa e pela qual é essencial lutar.

Total eccentricity index of some composite graphs
Authors: Nilanjan De  , Anita Pal  , Sk. Md. Abu Nayeem
Published: May 2023

The total eccentricity index of a graph G is the sum of eccentricities of all the vertices of G. In this paper, we first derive some sharp upper and lower bounds of total eccentricity index of different subdivision graphs and then determine some explicit expression of the total eccentricity index of the double graph, extended double cover graph and some generalized thorn graphs.

Published: May 2023

In this paper we have investigated two fluid axially symmetric cosmological models in $f(R, T)$ theory of gravitation. To get the deterministic model, we have assumed a supplementary condition $H_3=k H_1$, where $H_1$ and $H_3$ are Hubble parameters and $k$ is constant. Two-fluid model in $f(R, T)$ theory of gravitation, one fluid represents the matter content of the universe and another fluid is chosen to model the cosmic microwave background radiation. Some geometric aspects of the model are also discussed.
Lyapunov approach for stability of integro-differential equations with non instantaneous impulse effect
Authors: Anju Sood  , Sanjay K. Srivastava
Published: May 2023

In this paper an integro-differential system of equations, with fixed moments of non instantaneous impulse effects is considered. Sufficient conditions for stability and asymptotic stability of this system have been worked out. The investigations are carried out by means of piecewise continuous functions, analogous to Lyapunov functions and by means of the theory of differential inequalities for such functions. A new comparison lemma, connecting the solution of the given impulsive integro-differential system to the solutionof a scalar impulsive differential system is also established.
