Un nuevo tipo de migrante: ¿escapando del “desarrollo”?
Authors: Sassen Saskia
Published: July 2021

Aquí examino dos grupos de problemas, uno perteneciendo a una historia más vieja cuyas consecuencias aún están con nosotros, y el otro, a una nueva historia en proceso que hace visible cuánta injusticia marca nuestro período actual. El primero destaca el poder de la ley y de los acuerdos contractuales para destruir economías que no encajan en el molde corporativo/moderno. El segundo se enfoca en dos grandes micro-historias brutales en donde la ley puede a duras penas funcionar. En resumen, estos son tipos de “desarrollo” que destruyen medios de vida y destruyen la tierra y el agua. El resultado es desastroso. Sin embargo, los tipos de medidas que utilizamos para establecer el “desarrollo” registran estas condiciones negativas como positivas: un aumento en PIB per cápita. Ahora hay un creciente consenso entre expertos en desarrollo —notablemente Joseph Stiglitz y Amartya Sen— quienes sostienen que el aumento del PIB per cápita ya no es útil como medida para entender cuál es el estado de nuestras economías si la preocupación incluye la población general —y no se enfoca únicamente en modos particulares de aumento que funcionan para los ricos—.

Published: July 2021

Introduction: Estimating and monitoring changes in liver function tests is necessary to prevent the occurrence of chronic liver disease in HIV patients undergoing highly active antiretroviral therapy (HAART).
Objective: To determine the variation liver profile test levels in HIV patients undergoing HAART.
Materials and methods: Retrospective longitudinal study conducted in 100 HIV patients treated at the Hospital Nacional Hipólito Unanue, Lima, Peru, between 2015 and 2017. Patients in all stages of clinical infection under HAART and with liver function panel results for alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and total protein (TP) were included. Three follow-up liver function tests (every 3 months) were performed while undergoing HAART and participants were categorized as having normal or elevated levels for all liver markers. Differences between the samples analyzed were determined using the paired-samples T test, with a 95% confidence interval and a significance level of p<0.05.
Results: Participants’ mean age was 33±9.56 years and 67% were male. Mean serum AST, ALT and ALP values decreased between the first and the third measurement (p=0.021, p=0.076 and p=0.002, respectively). No significant differences in GGT and TP levels were observed between the three measurements, nor between patients with normal and elevated AST, ALT, ALP and TP values, but significant differences were observed for GGT (p=0.010).
Conclusions: Variations in liver marker levels were observed in all participants, with a decreasing trend in AST, ALT and ALP between the early and late stages of HAART, implying that this therapy could play a role in liver tissue damage.

Authors: Lin Chongliang , Song Dezhen , Jiang Haodong , Luo Lvqi , Bao Xi , Yu Xiaomin , Ma Jianshe , Wang Xianqin , Jiang Xiajuan
Published: July 2021

Eugenitin is a non-volatile chromone derivative which is always found in dried flower buds of Syzygium aromaticum L. (Merr.) & L.M. Perry. Until now, there were no reports about the pharmacokinetics of eugenitin in biological fluids. A UPLC-MS/MS method developed to determine eugenitin in mouse blood. The blood samples were prepared by protein precipitation with acetonitrile. Chrysin (internal standard, IS) and eugenitin were gradient eluted by mobile phase of acetonitrile and water (0.1% formic acid) in a BEH C18 column. The multiple reaction monitoring (MRM) of m/z 221.1→206.0 for eugenitin and m/z 255.1→152.9 for IS with an electrospray ionization (ESI) source was used for quantitative detection. The calibration curve ranged from 0.5 to 500 ng/mL (r > 0.995). The accuracy ranged from 98 to 113%, the precision was less than 12%, and the matrix effect was between 86 and 94%, the recovery was better than 81%. The developed method was successfully used for pharmacokinetics of eugenitin in mice after intravenous (5 mg/kg) and oral (20 mg/kg) administration, and the absolute availability of eugenitin was 12%.

Published: July 2021

RESUMO Com o aumento dos eventos extremos nas cidades, os gestores locais precisam tomar medidas que minimizem os impactos negativos resultantes dos desastres. A área de saúde é uma das que mais possuem interferências, com o crescimento do número de afetados, feridos, mortos, além dos problemas psicológicos e de qualidade de vida após os eventos. O objetivo da presente pesquisa foi analisar a resiliência a desastres na saúde por meio do instrumento global Disaster Resilience Scorecard for Cities. O Scorecard tem sido utilizado por diversos países para avaliar a resiliência de suas cidades quanto a preparação e resposta na ocorrência de eventos extremos. Por meio da sua aplicação, foi possível observar que apenas a utilização dessa ferramenta se mostra insuficiente para avaliar as diversas dimensões da área de saúde. Além disto, a análise dos Planos Diretores Municipais mostrou que ainda existe a falta de integração entre as medidas de saúde em relação às emergências. É necessário desenvolver leis e ferramentas mais eficientes na avaliação e monitoramento da saúde em caso de desastres, a fim de alcançar a resiliência para uma maior qualidade de vida da população.
Vulnerabilidade institucional do setor saúde a desastres: perspectiva dos profissionais e gestores de Nova Friburgo
Authors: Silva Isadora Vida de Mefano e , Freitas Carlos Machado de , Freitas Leonardo Esteves de
Published: July 2021

RESUMO Alguns países têm perdido até 50% da sua capacidade hospitalar em decorrência de eventos extremos. Aproximadamente 67% das instalações de saúde da América Latina e do Caribe localizam-se em áreas propensas a desastres. Considerando as condições de vulnerabilidade, esses desastres constituem uma ameaça à saúde pública. Se o próprio setor saúde é vulnerável, um determinado evento pode afetar a vida de mais pessoas, tanto trabalhadores e usuários que estão nos estabelecimentos de saúde no momento, se estes estão localizados em áreas de risco, como comprometendo a sua capacidade de resposta aos impactos desse evento na saúde da população. Boa parte dos estudos sobre desastres são realizados ouvindo a população, suas percepções e representações sociais. Entretanto, poucos estudos foram feitos sobre a percepção dos trabalhadores da saúde nesses desastres. Por meio de entrevistas com profissionais de saúde e gestores no município de Nova Friburgo, foi identificado que, além da vulnerabilidade das infraestruturas de saúde em áreas de risco, o setor também se torna vulnerável pela falta de preparação e de participação na elaboração dos planos municipais de gestão de risco, bem como pela falta de participação dos profissionais da ponta e das comunidades na elaboração dos planos do próprio setor.

Published: July 2021

Abstract Infection by the hepatitis C virus is more prevalent in patients on dialysis than in the general population in Brazil, and has been associated with worse outcomes. Current therapy for hepatitis C is highly effective, safe, and widely available in Brazil, with coverage provided to dialysis patients with chronic kidney disease, which makes the elimination of hepatitis C a viable target. The Brazilian Society of Nephrology, the Brazilian Society of Hepatology, and the Brazilian Liver Institute developed the “Brazilian Registry for the Elimination of Hepatitis C in Dialysis Units”. This project aims to identify, treat, and monitor the response to treatment of patients on chronic dialysis infected with the hepatitis C virus in Brazil. This article presents the issue and invites Brazilian nephrologists to rally around the achievement of a significant goal.
Regeneration of roots and seedlings from Eugenia involucrata seeds under water deficit conditions
Authors: Inocente Mariane Cristina , Barbedo Claudio José
Published: July 2021

Abstract: The aim of this study was to analyze the regenerative capacity of Eugenia involucrata seeds as a possible strategy to ensure the production of new seedlings when they are going through a period of water deficit. Progressive water deficit conditions over time (up to 60 days for seeds and 270 days for seedlings) and in intensity (up to -5 MPa for seeds and -10 MPa for seedlings) were simulated, and seedling regeneration was analyzed. The results showed that these seeds can survive even under the most extreme conditions (-5 MPa for 60 days) and some seedling tissues as well (-5 MPa for 270 days). Furthermore, roots and seedlings continued to develop from apparently necrotic tissue on the seed surface, showing that, when necessary, these seeds use their mechanism of formation of new roots and seedlings to ensure species survival under water stress conditions.

Published: July 2021

RESUMO Objetivo Comparar o processamento correferencial, em idosos com e sem a Doença de Alzheimer, no Português Brasileiro. Método Participaram 12 idosos sem Alzheimer (ISA), e 06 idosos com a Doença de Alzheimer (IDA). O Mini-Exame do Estado Mental foi utilizado para triagem cognitiva dos participantes. Dois experimentos foram realizados utilizando a técnica de leitura automonitorada para analisar o processamento da correferência, cada um contendo oito frases experimentais e 24 frases distratoras, um deles utilizou pronomes e nomes repetidos, já o outro utilizou hipônimos e hiperônimos. Após a leitura, foram realizadas perguntas relacionadas ao conteúdo das frases. A principal variável de interesse foi o tempo de leitura aferido após a apresentação das retomadas anafóricas. Resultados No primeiro experimento, foram encontrados resultados estatisticamente significantes, no grupo ISA os pronomes foram processados mais rapidamente do que nomes repetidos, e no grupo IDA, os voluntários foram mais rápidos na retomada do nome repetido. No segundo experimento, os resultados demonstraram que o grupo ISA apresentou preferência, na retomada anafórica, pelos hiperônimos, já o grupo IDA não apresentou diferenças significativas entre as condições. Conclusão Os idosos sem patologia processaram mais rapidamente pronomes e hiperônimos, quando comparados a retomadas com nomes repetidos e hipônimos, respectivamente, pela menor quantidade de traços semânticos necessários para identificar os antecedentes naquelas condições, assim como pela proeminência sintática e discursiva. Nos idosos com DA, os nomes foram lidos mais prontamente que pronomes, e não houve diferença no processamento anafórico envolvendo hipônimos e hiperônimos, podendo decorrer do comprometimento na memória de trabalho.

A recuperação das pessoas acometidas pela COVID-19 é um processo que continua para além do quadro agudo da infecção pelo Sars-CoV-2. O comprometimento de diversos sistemas corporais pode acarretar impactos funcionais e demandar assistência fisioterapêutica contínua tanto na atenção ambulatorial quanto na Atenção Primária à Saúde (APS). Neste ensaio, busca-se discutir os desafios da organização e da oferta de assistência fisioterapêutica em resposta a pandemia da COVID-19 no Brasil. A análise foi sumarizada em quatro dimensões: distribuição de fisioterapeutas no país; oferta da assistência fisioterapêutica na APS e na atenção ambulatorial; e oferta de atenção fisioterapêutica por Telessaúde. Conclui-se haver iniquidade na distribuição regional de fisioterapeutas no Brasil; a reabilitação funcional depende da capacidade de resposta da APS, a qual se encontra ameaçada pelo processo de desestruturação em curso; existe um déficit de serviços de reabilitação que antecede a pandemia, e pode não responder satisfatoriamente às demandas do atual contexto epidemiológico; faz-se necessária a articulação entre as equipes de fisioterapia ambulatorial e da APS; a telessaúde embora seja um recurso e uma oportunidade para ampliar o acesso da população à reabilitação funcional exige cautela; o fisioterapeuta possui papel crucial em todo o continuum de cuidados da COVID-19.
Performance of a cyclic miniature cone penetration test in dry granular soil: experimental approaches
Authors: de Lima Sonaglio G. , do Patrocínio G. M. A. , Festugato L. , Corte M. B.
Published: July 2021

Shaft friction degradation in geotechnical problems occurs alongside large uncertainties. Under cyclic loadings, offshore foundations can episodically suffer the loss of stiffness and strength. In such cases, initial in situ soil state is lost as soil is disturbed during cyclic loading. In this sense, it is important to develop a testing procedure to assess the lateral friction degradation. Considering that a cone is a miniature driven pile, the use of this testing technique allows monitoring the degradation of sleeve friction during cyclic loading. This paper aims to improve the knowledge on the feasibility of using cone testing for the recognition of lateral friction degradation of a dry granular soil. Cyclic miniature cone penetration tests were performed in a calibration chamber considering a range of loading conditions. The effect of cyclic displacement amplitude and the confining pressure were investigated. Lateral friction, fs, degrades while repeating the load cycling, resulting in loss of lateral strength due to soil–cone interface friction degradation. After about ten load cycles, degradation tended to stabilise for all tests.

Amaç: Nöronavigasyon ile intraserebral biyopsi sıklıkla daha derindeki ve ufak boyuttaki lezyonlarda kullanılan bir yöntem olduğu için hastalarda radyolojik ve nörolojik komplikasyonlar oluşturabilmektedir. Ayrıca minimal invaziv bir yöntem olduğu için kısıtlı doku örneği alınabilir ve buna bağlı histopatolojik tanı koyulmayabilir. Biz de bu çalışmayla nöronavigasyon ile intraserebral biyopsi sonuçlarımızın lezyon lokalizasyonuna ve boyutuna bağlı ne kadar etkilendiğini ortaya koymaya çalıştık.

Materyal ve Method: 2016 ve Mayıs 2021 yılları arasında bu yöntem ile opere edilmiş 41 hastanın dosyaları retrospektif olarak incelendi. Çalışmaya çerçevesiz nöronavigasyon ile biyopsi alınan hastalar dahil edildi. Belirlenen parametreler lezyonların yerine, hassas bölgede olup olmamasına ve boyutlarına göre değerlendirildi.

Bulgular: Çalışmaya dahil edilen 41 hastanın 26 (%63.41)' sının lezyonu hassas bölge, 15 (%36.58)' nin lezyonu ise hassas bölge dışı yerleşimliydi. Lezyon boyutları ortalama 34x27.76 mm idi. 38 (%92.68) hastanın doku örneklerine tanı koyulabildiği tesbit edildi. Operasyon sonrası çekilen kontrol BT' lerde 4 (%9.75) hastada radyolojik olarak komplikasyon görüldü. 3 (%7.31) hastada ise operasyon sonrası nörolojik komplikasyon mevcuttu. Cerrahiye bağlı mortaliteye rastlanmadı.

Sonuç: Cerrahi öncesi iyi planlama ve radyolojik görüntülerin hem radyolog hem de cerrah tarafından iyi incelenmesi lezyonun hassas bölgede ve küçük boyutta olmasının getirdiği radyolojik ve nörolojik komplikasyon riskini azaltmaktadır. Hedef dokudan birden fazla kadrandan biyopsi alınması histopatolojik tanı için yeterli doku elde edilmesini sağlar ve doğru tanı koyulmasına çok daha fazla yardımcı olur.

Published: July 2021

The article deals with the issues related to the possibility of diagnosing the technical condition of an asyn-chronous electric motor by an external magnetic field. The justification of the problems associated with the di-agnosis of electric motors is given. The difficulties that arise when measuring the external magnetic field of electric motors, as well as the devices with which it is possible to carry out measurements, are described. The re-lationship between the EMF of the sensor and the external magnetic field is shown. The results of processing the EMF waveforms induced by an external magnetic field in an inductive sensor for various electric motors are presented. The processing was carried out by the fast Fourier transform method. The external magnetic field contains the first harmonic and various harmonics that are multiples of the combination of the stator teeth, or the sum of the stator and rotor teeth that fall on one pair of poles. The ratio of the amplitudes of the first and tooth harmonics is affected by the measurement location and the orientation of the sensor. Diagrams showing the ratio of the main and tooth harmonics at different points of the motor body are constructed. The depend-ences of the harmonic amplitudes on the magnitude of the magnetizing current of the stator are given. Changes in the amplitudes and spectrum of harmonics in the presence and absence of an inter-turn short circuit in the stator winding are shown. Diagrams of the circular external magnetic field for the main and higher harmonics are constructed. The study shows the possibility of using an external magnetic field to detect inter-turn short circuits of the stator winding.

Grief and Stress Communication and Management in Euripides’ Iphigenia in Aulis
Authors:   Dept. of Classical Languages, Faculty of Arts, University of Peradeniya, Sri Lanka, Wickramasinghe Chandima S. M.
Published: July 2021

Communication, an essential human trait, is vital to develop a great connectedness among individuals as it helps to understand human mind and emotions. Grief and stress are communicated in different proportions in ancient Greek tragedies, which revolve around a plot that emanates grief. The characters in a Greek tragedy are affected by or are victims of a grieving situation central to the play. Aristotle maintained that tragic action must emanate pity and fear which are connected with grief and stress. Euripides, the revolutionary dramatist of Classical Athens, has empowered his characters to the effect of transmitting their sentiments freely. This feature is notable in his plays such as Alcestis, Electra, Ion, Orestes and Iphigenia in Aulis (IA). In IA, a well-established mythical account is presented as a simple family story. It is not just Iphigenia, who is affected by her impending tragedy. Almost all characters grieve in different proportions, while attempting to manage their grief and stress first by communicating it and then in ways peculiar to themselves. The strategies range from keeping a positive attitude, accepting the situations, to being assertive instead of being aggressive. This study examines the communication of grief and stress as a means of managing such sentiments with especial reference to Iphigenia in Aulis in order to understand how Euripidean tragedy could bring relief to its audience. In the process, the study observes how the dynamics of engagement of a character with others, their feelings, thoughts and intentions can contribute to manage grief and stress through effective communication of such sentiments.

Transgender is an Umbrella term to define the people whose gender identity and gender expression differ from their gender assign at birth. At present, the concept of transgender has acquired a great attention in the western world and the number of territories legally validate the transgender community and their rights through national legislations. Concerning South Asian context, the third gender concept is recognized by the Indian Supreme Court but unfortunately, the legal system of Sri Lanka is reluctant to amend the laws to ameliorate the position of the transgender community. This research mainly focused on transgender identity and the laws relating to the transgender community in Sri Lanka and India. The purpose of the research is to examine the existing laws relating to transgender identity in both countries. Moreover, this piece of work tries to identify the contribution of law in improving the position of the transgender community in these territories. Further, this work mainly used the comparative research method and based on internet retrieved documents. Through this work it suggests and identifies the ways and means to improve the condition of Sri Lankan transgender community. Recommendations will be made in this respect.

Published: July 2021

The purpose of this seven-month study is to closely examine the pre-school children’s activity which represents the stepping stone of reading interest as the fundamental aspect of literacy. The subject chosen were 38 students of two Prekindergarten–Kindergarten in Landungsari village, a citified area of Malang city, East Java Province, Indonesia. Doing initial survey, holding structured interview, reinvigorating the existing facilities, and networking with the local social units were the integrated approach done to intensify the study performed. Furthermore, the role of family and volunteers whose attention was dedicated to children development was also observed to find out their support in nurturing children to love reading. Aside from pilot data and primary data, secondary data from the local government recording the people’s education within the environment of the observed subjects were used as references to the prevalent reading culture. The result of the research disclosed that 28 and 15 children attending the two Prekindergarten–Kindergartens exposed their self-development through creativity based on their imagination after listening to the selected storytelling materials. Additionally, building visual communication and increasing numeric vocabularies were crucial indicators of the research subjects to love reading. The rise of this reading interest, nevertheless, cannot be detached from the collaboration between teachers or guides of the pre-schoolers and the individuals who are committed to the education of early age children; not to mention a conducive atmosphere and supporting programs from both formal and informal institutions.

Directed Methylation and Long-read sequencing (DiMeLo-seq) can be used to map protein-DNA interactions in repetitive regions, including the centromere. If you plan to use DiMeLo-seq for centromere mapping, then centromere enrichment is a valuable technique to increase the output signal and get more data. AlphaHOR-RES is a method to enrich for centromeres using MscI and AseI restriction digest. Refer to "DiMeLo-seq: Directed Methylation with Long-read sequencing" and "pA-Hia5 Protein Expression and Purification" on protocols.io for the rest of the DiMeLo-seq protocol.

Morphological and Functional Characterization of Hemocytes of the Black Sea Bivalves: Pacific Oyster (Crassostrea gigas) and Mussel (Mytilus galloprovincialis)
Authors: Andreyeva Alexandra Y.
Published: July 2021

To understand the role that hemocytes play in processes of cellular immunity of bivalve mollusks, they should be accurately classified based on their morphological and physiological characteristics. The circulating hemocytes of the cultured Pacific oyster (Crassostrea gigas) and marine mussel (Mytilus galloprovincialis) were investigated using light microscopy and flow cytometry. In the mussel, two cell types, granulocytes and agranulocytes, were identified based on the presence of two subpopulations of cells differing by size and granularity level on light scatter plots. Light microscopic examination confirmed the presence of cells with cytoplasmic granules and cells without granulation in hemolymph of the mussel. In the oyster, light microscopy and flow cytometry revealed three types of hemocytes: agranulocytes, hyalinocytes, and granulocytes. The cells in the hemolymph of both species were mainly represented by agranular cells, which constituted 78.4 ± 8.9 % in the mussel and 86.7 ± 2.7 % (agranulocytes and hyalinocytes) in the oyster. Agranulocytes were the smallest cell type in the mussel and oyster. They were round-shaped and had large nuclei and narrow cytoplasm. Hyalinocytes of the oyster were larger and irregularly shaped, with eccentric nuclei. Granulocytes of both species contained numerous eosinophilic, basophilic, and mixed granules and formed pseudopodia. Flow cytometry showed that the agranular hemocytes of both species produced considerably fewer reactive oxygen species compared to granulocytes. Morphological and functional characterization of hemocytes of cultivated species improves the analysis of physiological state of bivalve mollusks farmed in the Black Sea region

Authors: Terbeche Mekki
Published: July 2021

In this paper we study the estimation of a multivariate normal mean under the balanced loss function. We present here a class of shrinkage estimators which generalizes the James-Stein estimator and we are interested to establish the asymptotic behaviour of risks ratios of these estimators to the maximum likelihood estimators (MLE). Thus, in the case where the dimension of the parameter space and the sample size are large, we determine the sufficient conditions for that the estimators cited previously are minimax

Authors: Loginov Dmitry A. , Demenchuk Sergey V. , Islamov Sergey R.
Published: July 2021

The results of work on increasing the efficiency of heat energy production in standard boiler units using the «TERMOKOKS-KS» technology by intensifying the energy-technological processing of coal in a fluidized bed are presented. A significant increase in productivity has been established when removing small grades from coal and subsequent drying of coal, which makes it possible to reduce the cost of the obtained heat energy. The coarsening of the particles of the obtained browncoal coke with a decrease in the moisture content of the coal was revealed, which increases its transport characteristics. The range of temperatures of stable operation of the fluidized bed has been increased, due to which the product range of the «TERMOKOKS-KS» process has been expanded. The heat and material balances of the processes of combined production of heat energy and carbon-containing products are presented

Mathetical problem of banking assets diversification
Authors: Kulian V. R. , Yunkova O. O.
Published: July 2021

In article we consider a problem of optimal investment strategy by a commercial bank building. This task is actual and the development of a procedure to solve it can help in making investment banking decisions. The general formulation of the problem consists of two criteria. The first one is to maximize the expected return, and the second is to minimize the risk of the investment transaction. Mathematical formulation of the problem is considered as a problem of nonlinear programming under constraints. The procedure for solving such a two-criteria optimization problem allows to obtain many solutions, which requires further steps to make a single optimal solution. According to the algorithm proposed in the work, the problem is divided into two separate problems of single-criteria optimization. Each of these tasks allows to obtain the optimal values of the investment vector both in terms of its expected return and in terms of investment risk. Additional constraints in the mathematical formulation of the problem, make it possible to take into account factors that, from the point of view of the investor, may influence decision-making. The procedures presented in this work allow to obtain analytical representations of formulas that describe the optimal values of the investment distribution vector for both mathematical formulations of the problem.

Application of fuzzy logic in finding the optimal filter in optoacoustics problems

Published: July 2021

Denoising is an important step in the early stage of signal preprocessing in optoacoustic applications. The efficiency of such modern noise removal methods as wavelet or curvlet filtering depends significantly on the numerical combinations and forms of wavelet transform parameters, and the multidimensional extension of such filters is rather non-trivial. These issues are serious obstacle for using of these highly effective filters in the tasks of optoacoustic reconstruction, especially in real laboratorial or medical practice. The objective of our study was to find the optimal filter, convenient for use in laboratorian and medical practice, when the types of noise are a priori unknown, and the filter settings should not take much time. In the offered work spatial filters which have only one parameter of adjustment - the size of a window are considered. Three-dimensional extensions of such well-established denoising techniques, as mean filter, median filter, their adaptive variants (Wiener spatial filter and modified median filter), as well as iterative truncated arithmetic mean filter were analyzed. The proposed filters were tested on a test set that contains versions of Shepp-Logan's three-dimensional phantom with mixtures of Gaussian and alpha-stable noise, as well as speckle noise. The identification of the best filter for simultaneous suppression of these types of interference was carried out using the theory of fuzzy sets. In our tests, a modified median filter and an iterative truncated arithmetic mean filter were rated as the best choice when the goal is to minimize aberrations when noise is not known a priory.
Conditions for the solvability of nonlinear equations systems in Euclidean spaces
Authors: Kashpur O. F.
Published: July 2021

The solution of many applied problems is to ﬁnd a solution of nonlinear equations systems in ﬁnite- dimensional Euclidean spaces. The problem of ﬁnding the solution of a nonlinear system is divided into two problems: 1. The existence of a solution of a nonlinear equations system; in the case of nonunique of the solution, it is necessary to ﬁnd the number of these solutions and their surroundings. 2. Finding the solution of a system of nonlinear equations with a given accuracy. Many publications are devoted to solving problem 2, namely the construction of iterative methods, their convergence and estimates of the solution accuracy. In contrast to problem 2, for problem 1 there is no general algorithm for solving this task, there are no constructive conditions for the existence of a solution of a nonlinear equations system in Euclidean spaces. In this article, in ﬁnite-dimensional Euclidean spaces, the constructive conditions for the existence of a solution of nonlinear systems of polynomial form are found. The connection of these conditions with the linear polynomial interpolant of the minimum norm, generated by a scalar product with Gaussian measure and the conditions of its existence, is given.
ENGLISH FOR ACADEMIC PURPOSES: KEEPING UP WITH THE TIMES
Authors: Ilchenko Olga , Kramar Natalia
Published: July 2021

English language education, especially in light of the status of English as present-day lingua franca, has become a prolific field of research, and no less prolific area of practical application internationally. Through a critical literature review, the current study addresses one of its most prominent subfields – English for Academic Purposes – with special emphasis on academic writing. We briefly touch upon its evolution and identify the terminological ambiguities involved in EAP conceptualization within the broader framework of ESP (English for Specific Purposes). By examining the changes that academic English is undergoing today due to the overwhelming influence of L2 speakers’ varieties (termed “similects” by Anna Mauranen), we elucidate how English as a Lingua Franca movement can benefit and enrich EAP pedagogic practice. We also discuss how EAP fits within the latest CEFR guidelines, paying close attention to mediating skills, critical thinking and integrative thinking skills, which, as we argue, need to be more extensively incorporated into academic writing instruction. We discuss the rationale and the methodological principles of English for Research Publication Purposes as a new offshoot of EAP, which combines genre-based instruction with the exploration of multiple non-linguistic issues, involved in academic publishing, such as interaction with editors and gatekeepers, choosing a suitable journal, navigating the review process. We hope to demonstrate that EAP teaching, and especially academic writing instruction, is in need of major revision to overcome the yawning gap that currently exists between theory and practice.
