Development of Curved Shape Diffuser Duct for Aero Engines With a Backend Centrifugal Compressor
Authors: Kumar Akchhay , Mistry Chetankumar , Kumar Sankar , Pratap Ajay
Published: August 2024

In the present study, a design of the curved shape diffuser-duct is proposed to apply to the compressor stage for aero-engines with a backend centrifugal compressor. For these configurations, the flow exiting radially from the centrifugal impeller needs to be changed from radial-to-axial direction to meet downstream combustion chamber requirements. Hence, the specially designed exit duct with a curved shape to manage the flow from the radial-to-axial direction was later diffused using the diffuser-shaped exit duct. This study aims to design and develop an efficient diffuser-duct for the adequate deceleration of flow in the exhaust diffuser and, as a result, a uniform and low-velocity flow at the exit. This configuration comprises a radial-to-axial turning annular passage at the centrifugal impeller exit. Then, the passage is directed to either a purely axial direction or is inclined to the axial direction by a slight angle. The results indicate a uniform total pressure at the stage exit with marginal variation along the span. It shows equivalent end wall effects near both the shroud and hub surfaces. This endwall effect may be occurring mainly due to the growth of the boundary layer across the diffuser passage.

Ammonia is a fundamental component in fertilizer and chemical manufacturing processes around the world, but its production is a significant contributor to CO2 emissions in chemical industry. Implementation of carbon capture utilization and storage (CCUS) offers an alternative decarbonisation strategy to mitigate CO2 emissions in ammonia production. This study assesses the environmental performance of ammonia production through life cycle assessment (LCA) methodology. Environmental impacts are calculated using openLCA software with various impact assessment methods, including CML IA Baseline, Impact 2002+, Recipe 2016 Midpoint (H), and AWARE. The study scope encompasses the cradle-to-grave analysis, from the extraction of raw materials and transportation to ammonia production, main processes, distribution, and consumer product consumption, with a declared unit of 1-kg ammonia product. Our findings showed that CO2 removal and Power Plant in core processes in the core process as the most significant contributors to Global Warming Potential. Therefore, sensitivity analysis was conducted by reducing CO2 emission by 10% and 70% through CCUS implementation. The results showed that the CCUS implementation could reduce Global Warming Potential by up to 43%.

Published: August 2024

According to Presidential Regulation No. 35 of 2018, which focuses on accelerating the development of waste-to-energy projects, Denpasar City in Bali has been identified as one of the key Indonesian cities for implementing these projects. The daily waste generation in Denpasar City is estimated at 750 tons. The city's sanitation strategy outlines that 20% of this waste will be reduced at its source, while the remaining 80% is managed at the final treatment site. This study employs the Life Cycle Analysis (LCA) approach to evaluate the environmental impacts of traditional landfilling and various thermal waste treatment methods. The findings reveal that gasification (Scenario 2) has the lowest Global Warming Potential (GWP), with 779,759 kg CO2 equivalent emitted, indicating its superiority in reducing greenhouse gases. In contrast, landfilling (Scenario 1) is the least favorable, with a GWP of 2,885,770 kg CO2 equivalent and a significant cancer risk due to hexavalent chromium emissions estimated at 1,634,050 kg equivalent. These results underscore the health and environmental hazards of landfilling. Further, the study delves into each treatment scenario's impact on acidification, eutrophication, global warming potential, and photochemical oxidation.
Anticancer Efficiency of Reovirus in Normoxia and Hypoxia
Authors: Figová K. , Hraběta J. , Eckschlager Tomáš
Published: August 2024

Oncolytic viruses infect, replicate in, and lyse tumour cells but spare the normal ones. One of oncolytic viruses is a naturally occurring replicationcompetent reovirus (RV), which preferentially kills tumour cells with activated Ras signaling pathways. The aim of this study was to survey effects of RV on brain tumour-derived cells in vitro under hypoxic conditions since hypoxia causes resistance to radioand chemotherapy. This study demonstrates that RV replicates preferentially in tumour cells and that the virus is able to overcome cellular adaptation to hypoxia and infect and kill hypoxic tumour cells. RV can both replicate in hypoxic tumour microenvironment and cause the cytopathic effect, subsequently inducing cell death. We found that a large proportion of cells are killed in hypoxia (1% O2) by caspaseindependent mechanisms. Furthermore, we learned that the cell death induced by RV in hypoxic conditions is not caused by autophagy.

Published: August 2024

The foot and mouth disease virus (FMDV) causes a vesicular and contagious disease of clovenhoofed animals. In this study, the virus was isolated from vesicles of the infected cattle using cell culture and serotyped by ELISA test. The extracted RNA from the infected cells was reverse transcribed and amplified using VP1 gene-specific primer pairs by means of one-step RT-PCR. The purified VP1 gene was sub-cloned into the uniqe KpnI and BamHI cloning sites of the pcDNA3.1+ vector. The DH5α strain of E. coli was transformed by the vector. The sequences of sub-cloned FMDV type O/IRN/2007 VP1 were aligned with FMDV type O/UKG/2001 VP1 using MegAlign software. Nucleotide sequence comparisons were made using the BLAST software available from the NCBI website. The amino acid sequences of three sub-cloned FMDV type O/IRN/2007 VP1 were also aligned with three other similar sequences using MegAlign software. Nineteen of the most similar VP1 nucleotide sequences (by BLASTN program), FMDV O/IRN/2007 VP1 sequence, twenty isolates of FMDV-O VP1 in Iran and eight topotypes of FMDV type O were aligned by Mega5 to create a FMDV-O VP1-based sequence similarity tree. The nucleotide sequence comparison indicated that FMDV O/IRN/2007 VP1 had the greatest nucleotide sequence similarity to the VP1 gene of FMDV O1/Manisa/Turkey/69 (99 %), FMDV O1/Manisa/Netherlands (98 %) and FMDV O1/Manisa/iso87/Turkey (98 %). It was also observed that the highest identity between FMDV O/IRN/2007 VP1 sequence and other nucleotide sequences of FMDV type O VP1 genes isolated in Iran during 1997–2004 was about 91 %.
Transfer of Ser7 Phosphorylated CENP-A from Centromere to Midbody During Mitosis in MCF-7 Cells
Authors: Liu R.-M. , Tian X.-Y. , Huang X.-T. , Zhou Hao
Published: August 2024

Serine 7 of centromere protein A (CENP-A) is a very important mitosis-specific phosphorylation site. In this study, we demonstrate the subcellular distribution of Ser7 phosphorylated CENP-A during mitosis in MCF-7 cells. The Ser7 phosphorylation of CENP-A was observed beginning at prophase at centromeres. Upon progression of mitosis, the fluorescence signals emerged in the central region of the metaphase plate and were maintained until anaphase at centromeres. At late anaphase, the fluorescence signals moved to the midzone gradually and transferred from the centromere to the midbody completely at telophase. They were compacted into the centre of the midbody in a thin cylinder consisting of a sandglass-like “mitotic machine” with microtubules and condensed chromosome. We also found that Ser10 phosphorylated H3 and Thr11 phosphorylated H3 were co-localized at the midbody in two bell-like symmetrical bodies with Ser7 phosphorylated CENP-A during the terminal stage of cytokinesis. Midbody isolation and immunoblotting experiments also indicated that Ser7 phosphorylated CENP-A are components of the midbody. These findings suggest that Ser7 phosphorylated CENP-A acts as a chromosomal passenger protein and may play an important role in cytokinesis.

Published: August 2024

α-Actinin 4, encoded by ACTN4, is an F-actin crosslinking protein which belongs to the spectrin gene superfamily. It has a head-to-tail homodimer structure with three main domains. Mutations in ACTN4 are associated with idiopathic nephrotic syndrome (NS). However, until today only a few mutations have been described in this gene. We used genomic DNA of 48 patients with focal segmental glomerulosclerosis (FSGS) and minimal change disease (MCD) to screen for ACTN4 mutations by high-resolution melting analysis (HRM). Suspect samples were sequenced and compared with healthy controls. To investigate the prevalence and possible effect of some substitutions found in FSGS/MCD patients we also looked for these changes in patients with IgA nephropathy (IgAN) and membranous glomerulonephritis (MGN). We found 20 exonic and intronic substitutions in the group of 48 Czech patients. The substitution 2242A>G (p.Asn748Asp) is a candidate mutation which was identified in one patient but not in any of the 200 healthy controls. Exon 19 seems to be a variable region due to the amount of revealed polymorphisms. In this region we also found three unreported substitutions in IgAN patients, c.2351C>T (p.Ala784Val), c.2378G>A (p.Cys793Tyr) and c.2393G>A (p.Gly798Asp). These substitutions were not found in any tested healthy controls. To conclude, the ACTN4 mutations are not a frequent cause of FSGS/MCD in Czech adult patients. One new ACTN4 mutation has been identified.

In particular, it is unique. The main novelty is the global in time aspect of this solution. The proofs use the coupling between the temperature and the velocity of the fluid, energy methods, and compactness argument.
Complexiton and interaction solutions to a specific form of extended Calogero–Bogoyavlenskii–Schiff equation via its bilinear form
Authors: Khareng Sukri , Ünsal Ömer
Published: August 2024

In this article, we are focusing on an extended Calogero–Bogoyavlenskii–Schiff equation which was altered originally from a new generalized fourth-order nonlinear differential equation that obtained from Calogero–Bogoyavlenskii–Schiff equation. We apply simplified Hirota method, which is an exclusive form of the direct Hirota bilinear method, to a specific form of a new generalized fourth-order nonlinear differential equation. The key point in applicability of referred method is attainability proper forms of dispersion relations and phase shifts. Through this procedure, we present different types of solutions for three different cases. We also give constrictions for each solution type in this work so that readers can distinguish differences among types of solutions. In addition, we introduce some graphical representations for obtained solutions, even for existence of complexiton and interaction solutions.

Authors: Bratton Shauna , Taylor Megan K. , Cortez Priscilla , Schiattarella Antonio , Fochesato Cecilia , Sisti Giovanni
Published: August 2024

Objectives

Atenolol is a commonly used beta bloscker in non-pregnant women. Many providers are hesitant in prescribing atenolol in pregnancy because of a possible association with poor fetal growth. We aimed to assess the association between atenolol and the occurrence of small for gestational age neonates compared to other beta blockers, as described in the existing literature.

Methods

We used the meta-analytic method to generate a forest plot for risk ratios (RR) of small for gestational age in patients who used atenolol vs. other beta blockers. Statistical heterogeneity was assessed with the I2 statistic.

Results

Two studies were included, with a resultant RR of 1.94 [95 % confidence interval (CI) 1.60; 2.35]. A study by Duan et al. in 2018 noted the following rate of small for gestational age for each beta blocker use: 112/638 atenolol, 590/3,357 labetalol, 35/324 metoprolol, and 50/489 propranolol. A study by Tanaka et al. in 2016 noted the following rate of small for gestational age: 8/22 for propranolol, 2/12 for metoprolol, 2/6 for atenolol, 0/5 for bisoprolol. Heterogeneity (I2) was 0 %.

Conclusions

Our results suggested an elevated risk of small for gestational age associated with atenolol use in comparison to other beta blockers, specifically labetalol, propranolol, bisoprolol, and metoprolol.

Authors: Alsidrani Fahad , Kılıçman Adem , Senu Norazak
Published: August 2024

Fractional partial differential equations (FPDEs) have gained significant attention in various scientific and engineering fields due to their ability to describe complex phenomena with memory and long-range interactions. Solving FPDEs analytically can be challenging, leading to a growing need for efficient numerical methods. This review article presents the recent analytical and numerical methods for solving FPDEs, where the fractional derivatives are assumed in Riemann-Liouville’s sense, Caputo’s sense, Atangana-Baleanu’s sense, and others. The primary objective of this study is to provide an overview of numerical techniques commonly used for FPDEs, focusing on appropriate choices of fractional derivatives and initial conditions. This article also briefly illustrates some FPDEs with exact solutions. It highlights various approaches utilized for solving these equations analytically and numerically, considering different fractional derivative concepts. The presented methods aim to expand the scope of analytical and numerical solutions available for time-FPDEs and improve the accuracy and efficiency of the techniques employed.

O PROBLEMA DA FORMA ASPECTUAL NA CONCEPÇÃO DE SEARLE SOBRE O INCONSCIENTE
Authors: De Athayde Prata Tárik
Published: August 2024

O artigo examina o papel do conceito de ‘forma aspectual’ – o fato de toda representação representar seu objeto sob certos aspectos, e não outros – na argumentação de Searle para sustentar uma teoria disposicional do inconsciente. Após uma discussão dos argumentos de Searle para a conexão entre a intencionalidade inconsciente e a consciência (seção 2), são discutidas as razões para aceitar que a forma aspectual tem existência objetiva (seção 3) e o modo como a causação mental inconsciente exige a presença de propriedades mentais ocorrentes (seção 4). A única razão para Searle negar a existência mental inconsciente é a sua restriçãoexcessiva, e injustificada,ao ponto de vista subjetivo da experiência consciente (seção 5).
TOMÁS DE AQUINO E JOHN FINNIS: DA TRADIÇÃO À NOVA ESCOLA DA LEI NATURAL
Authors: Ezídio Camila
Published: August 2024

Este artigo perpassa dois momentos da história das teorias da lei natural: em primeiro lugar, Tomás de Aquino que representa a tradição na investigação do conceito e, em segundo lugar, a discussão contemporânea de John Finnis que representa, particularmente, a quebra dessa tradição. A escolha por esses autores não é aleatória visto que, a filosofia de Tomás é considerada por diversos comentadores como uma das teorias mais importantes acerca da lei da natureza e a teoria de Finnis, por outro lado, é uma das mais conhecidas e criticadas na literatura atual sobre a lei. Dito isso, o objetivo deste artigo é, além de apresentar a teoria de cada um dos autores supracitados, discutir algumas questões que surgem a partir da conexão entre Tomás e Finnis que é estabelecida por este segundo, na medida em que ele tem em Tomás uma fonte de autoridade para seus argumentos. Desse modo, por vezes, com o texto de Finnis temos a impressão de estar frente a uma releitura da teoria do aquinate, mas logo compreendemos que essa releitura extrapola os limites aceitos para uma reinterpretação que não distorça a argumentação original. Por consequência, encontramos em Finnis uma teoria com inúmeros problemas do ponto de vista teórico e prático, argumento defendido por comentadores como William May, Jeremy Shearmur e Russel Hittinger os quais serão apresentados durante este texto.
TEMPORALIDADE E METAFÍSICA EM MATÉRIA E MEMÓRIA, DE HENRI BERGSON
Authors: Marques Trevisan Heliakim
Published: August 2024

O presente artigo visa desenvolver a relação temporal entre corpo e espírito apresentada por Bergson em Matéria e memória, e a maneira como essa relação pressupõe uma crítica ao espaço homogêneo. A partir disso, detemo-nos na definição de presente como materialidade da percepção, seu aspecto irredutível e suas consequências para uma teoria dos planos de consciência, para a qual o presente é sempre o último plano de uma totalidade psíquica. Visamos, com isso, perceber como são os termos temporais desta psicologia a condição para uma teoria do conhecimento que não separa a consciência da realidade exterior. Por isso, explora-se o vínculo interno entre psicologia, metafísica e teoria do conhecimento em Bergson. Por fim, ver-se-á como a metafísica surge de uma questão posta à finalidade pragmática.
O MELHOR DOS TEMPERAMENTOS POSSÍVEIS: A MÚSICA SPECULATIVA DE LEIBNIZ
Authors: Fortes Fabrício
Published: August 2024

Este trabalho investiga os aspectos fundamentais do pensamento de Leibniz acerca da música. A partir de uma análise da tese leibniziana de que a recepção estética do fenômeno musical consiste em um exercício oculto ou inconsciente da aritmética, identificam-se dois pressupostos à luz dos quais é possível traçar as linhas gerais da concepção do autor sobre o tema. De posse dessa caracterização geral, busca-se determinar de modo mais preciso a posição de Leibniz sobre a música no que diz respeito à questão do temperamento. Sustenta-se, a partir de evidências textuais e a despeito de uma interpretação tradicional, que não pode ser atribuída ao autor uma posição puramente racionalista, vinculada ao pitagorismo, e que algumas de suas teses sobre o tema o aproximam de um empirismo musical.
QUEBRANDO A CIRCULARIDADE: PERCEPÇÃO E CAUSALIDADE EM THE ANALYSIS OF MATTER
Authors: Cani Renato Cesar
Published: August 2024

Neste artigo, investigamos que tipo de noção de causa precisa ser pressuposta por Russell (1921; 1927) na defesa da teoria causal da percepção. Um dos propósitos da teoria causal é fornecer uma fundamentação epistemologicamente satisfatória para o conhecimento científico. Entretanto, não está claro que a definição de causa como regularidade sequencial – proposta por Russell em 1912 – atenda aos requisitos dessa teoria. A partir de algumas objeções levantadas por Eames (1989), que identifica uma circularidade viciosa no argumento de Russell em favor da teoria causal, sustentamos que a noção de causa requer uma caracterização ontologicamente mais robusta. Nesse sentido, sugerimos que o argumento de Russell acerca da teoria causal se beneficiaria de uma noção de causa análoga àquela proposta pelo realismo de capacidades de Cartwright (1989; 1999). Basicamente, atribuir uma capacidade a um objeto equivale a afirmar que ele possui uma tendência estável para causar determinados efeitos nas circunstâncias apropriadas. Apesar de metafisicamente robusta, a noção de capacidade proposta por Cartwright é compatível com uma interpretação empirista da ciência. Argumentamos que a aproximação entre a teoria causal da percepção e o realismo de capacidades indica que a teoria causal possui certa independência com relação aos demais pressupostos assumidos pelo realista estrutural epistêmico.
O QUE PLATÃO PERMITIRIA [JEREMY WALDRON]
Authors: Silva Marcos Antonio Da
Published: August 2024

Neste ensaio, Waldron propor aos que lidam com a filosofia política lançar um novo olhar na leitura das principais obras e autores, tanto da filosofia política clássica, quanto da filosofia política contemporânea, o que traduz uma nova forma, até mesmo metodológica, de interpretar os textos do pensamento político ocidental e, em última análise, fazer filosofia, quando nos dedicamos a escrever e a expor nossas ideias. O ponto de partida são algumas das reflexões de Platão levadas a efeito em A República, principalmente, e na Leis, em que se discutem os elementos constitutivos de uma sociedade política ideal e qual seria, realmente, a intenção dele ao projetar os atributos dessa sociedade imaginária criada na cabeça de Platão.

Published: August 2024

Trata-se da exploração da hipótese da presença de elementos gnósticos em O ser e o nada, de Jean-Paul Sartre. Primeiramente, mediante reconstrução das análises de Gerd Bornheim e Joseph Fell, pretende-se enfatizar as consequências niilistas da ontologia sartreana. Em um segundo momento, será mapeada a presença de temas e de um imaginário gnóstico, tal como proposto por Hans Jonas, no existencialismo sartreano. Por fim, a hermenêutica narrativista de Ricoeur será apresentada como via por meio da qual é possível se desviar das consequências niilistas do existencialismo.
Hannah Arendt: a importância da sociabilidade em um estado democrático de direito
Authors: PADILHA ROSSANA BATISTA , Lemos Martins Caroline
Published: August 2024

: Para que se possa abordar a sociabilidade em Hannah Arendt (1906-1975), é importante mencionar a importância que a autora confere, em suas obras, à necessidade de organização dos grupos humanos por meio de regras, assim como de que essas regras sejam seguidas para a preservação da vida em conjunto. Segundo a autora, a política é a maneira humana de convívio entre os homens e mulheres por meio do gerenciamento de questões emergentes, sem o uso de qualquer coação. Ainda, para ela, a igualdade não se origina da linhagem, do status social, mas da igualdade no sentido de poder agir em conjunto. Assim o indivíduo tem um importante papel a ser exercido na esfera política, enquanto cidadão. Nesse contexto, é preciso que haja um “espaço público”, bem como, que os cidadãos tenham a liberdade para expressar-se, podendo contestar, discutir as ideias e ideais, sem utilizar-se de qualquer tipo de violência, buscando, por meio dessa elaboração conjunta, adquirir outros direitos, por exemplo, à saúde, à educação, à moradia, ao emprego. A existência da possibilidade de ver e ser visto, discordar e poder expor isso, para Arendt, apenas ocorre em uma convivência política, na pluralidade, buscando a elaboração de regras para a organização do grupo em que vivem e pelo qual se sentirão partícipes e responsáveis. Ou seja, é uma atitude que ocorre em um espaço público de encontro de iguais, enquanto cidadãos, diferentes, enquanto seres únicos por nascimento, a fim de conseguir, mesmo que momentaneamente, a garantia de paz no convívio das singularidades. O presente texto visa a destacar a importância da necessidade dos laços de sociabilidade em um Estado Democrático de Direito, a partir da obra Origens do Totalitarismo, no qual Arendt descreve o Regime Totalitário vivenciado por ela, bem como, a ruptura dos laços de sociabilidade, fatos passíveis de discussão para pensar a situação política, não somente do Brasil como também de outros estados considerados democráticos. 
PALAVRAS-CHAVE: Arendt; Política; Sociabilidade; Ordenamento Jurídico; Totalitarismo.

“In a very real sense young children are citizens of the world” – Kinder und Jugendliche als Kriegsopfer in der Pädagogik Minna Spechts
Authors: Engelmann Sebastian
Published: August 2024

After the Second World War, children and young people in Germany had to be supported pedagogically. Minna Specht, an exiled educator, developed an educational programme that valued children and young people, not as the perpetrators but as victims of the war, and made it possible to deal with them pedagogically after the Second World War. This text elaborates on Minna Specht’s concept and points out that exiled educators had plenty of ideas about education after the Second World War that are rarely taken into account.

Published: August 2024

En este artículo se redefinen los tradicionales criterios que se tienen en cuenta al considerar que una pieza léxica es neológica. Los continuos cambios tecnológicos, la importancia de las redes sociales y las decisiones adoptadas por la RAE han dado lugar a que se modifiquen, en mayor o menor medida, los parámetros para considerar cuándo estamos o no ante un neologismo. Es perceptible la importancia del factor social, sobre todo si tenemos en cuenta la variable etaria, sin olvidar la perspectiva psicológica. Del mismo modo, el parámetro temporal adquiere una dimensión distinta, al igual que el lexicográfico.
Medición psicofisiológica de las emociones políticas. Un análisis de sus antecedentes y propuesta metodológica
Authors: López Córdoba David , Cazorla Martín Ángel , Martín-Lagos Ángel
Published: August 2024

El presente trabajo examina la pertinencia y las limitaciones de los modelos tradicionales de predicción electoral en el campo de la Ciencia Política. Se señala cómo los métodos clásicos basados en variables sociodemográficas y actitudinales están perdiendo precisión debido a la información incorrecta proporcionada por los encuestados y al giro emocional derivado de la espectacularización de la política. Se destaca la necesidad de buscar nuevos enfoques que incorporen la medición de las emociones, principalmente basados en la teoría de la inteligencia afectiva de George Marcus, con el apoyo de técnicas de medición psicofisiológica. Se observan estudios que han utilizado la electroencefalografía (EEG) y la variabilidad de la frecuencia cardiaca (VFC) para predecir el comportamiento electoral con mayor precisión que los métodos tradicionales, así como modelos de determinación de la emoción de manera automática. A fin de resolver los problemas de los modelos actuales, se propone la creación de un nuevo modelo que combine el autoinforme y la respuesta fisiológica para mejorar la predicción del comportamiento político.

Missionary activity of Tobolsk-Tyumen diocese in the north of Western Siberia in the 1990s — 2010s
Authors: Tkacheva Tatiana , Kharina Natalia
Published: August 2024

The article examines the main directions, forms and methods of missionary activity of the Tobolsk-Tyumen diocese among the indigenous population of the North of Western Siberia in 1990 – 2010. The research was based on publications in the diocesan periodical press, the works of the Tobolsk Theological Seminary, field materials of the authors. The article examines the state of Orthodoxy among the indigenous population by the early 1990s, the specifics of the organization and implementation of the diocesan mission in the territories of the Khanty-Mansi Autonomous Okrug (KhMAO) and Yamalo-Nenets Autonomous Okrug (YANAO). It is shown that in the post-Soviet period, in the conditions of changing relations between the state and the Russian Orthodox Church, the restoration of its missionary activity and the expansion of the Orthodox space in the historically nurtured territories gradually took place. It is concluded that educational, apologetic, informational forms of work were the most common in the missionary activity of the Tobolsk–Tyumen diocese in the North of Western Siberia in 1990 - 2010. The fulfillment of socially significant functions by the diocese contributed to the expansion of the Orthodox presence in the territory. In the 1990s, the missionary activity of the diocese among the indigenous population of the North was limited due to insufficient material and financial situation, lack of personnel and premises for religious rites, parish work. In the 2000s, in the context of establishing stable ties with government administrations of various levels, missionary activity acquired a large-scale character. The article notes that the practice of the Orthodox mission has led to the development of recommendations for the organization of missionary work among the indigenous population, and the specifics of the activities associated with the remoteness and inaccessibility of the northern territories – to the emergence of new forms of missionary expedition.

Published: August 2024

To create modern competitive and trusted software, it is necessary to use knowledge of formal methods. Currently, a huge number of students are studying specialties related to programming. However, when studying at a university, it is difficult to gain the skill of practical application of theoretical knowledge. Short competitions with non-standard, industrial-related problems can arouse students' interest in the field of formal methods. The article describes the first experience of organizing a competition in formal verification of programs among students of Russian universities. The competition was held in conjunction with a seminar on program semantics, specification and verification (PSSV) in Innopolis in November 2023. The format of the competition was close to the format of so-called hackathons. Participants were asked to solve verification problems using predefined model checking and deductive verification tools. We consider the issues of organizing such an event, proposed tasks, results of decisions and feedback from participants.

The aim of the study is to compare the oral speech of Soviet and Russian young people aged 13 to 23 years. The analysis was carried out according to a single indicator: the abundance of structurally incomplete statements in transcribed oral messages. Speech samples of both Soviet and modern Russian teenagers are taken from the media. As a result of the study, it was shown that Soviet schoolchildren and students used structurally incomplete statements in their oral speech 7 times less than modern youth. The study is a continuation of a more extensive comparison of the oral speech of schoolchildren and students of the Soviet and Russian eras, as well as speech role models that were broadcast by the Soviet and Russian media. The basis for the choice of research material was the non-trivial task of establishing the role of the influence of the modern media environment on the speech of adolescents. If Soviet schoolchildren and students consumed media content with the best linguistic role models for their time, then modern teenagers are formed in the free Internet environment. In the course of the study, a method was developed for objective comparison of the speech of different speakers. Text corpora were compared by the number of occasionalisms, author's syntagmas, phraseological units, professionalisms, clericalisms, vulgarisms, structurally incomplete statements, obscene vocabulary, etc. In a series of studies, it was shown that the speech samples of the Soviet era, that is, the Soviet group, are better both quantitatively and qualitatively than modern ones. The scientific novelty lies in the assessment of the oral speech of the speakers of information and entertainment media products of the media of one Russian-speaking country, but in different eras, although close in time, using a new complex method of linguistic analysis. The key factors that influenced the speech approaches of the creators of these media products were rapid social and technical changes.
Functional and Sеmantic Analysis of the Case Markers in Vakh Khanty (a Case Study of the Latest Field Data on LingvoDoc)

In this paper we argue that the category of nominal case in the Vakh Khanty dialect needs reviewing which is due to the availability of the recent field data obtained in 2019. This objective is considered to be topical because the results of the study will equip researches with all necessary data to develop a unified notation system for the case markers to be used in an annotated corpus of Vakh Khanty on the LingvoDoc platform. The declension system of the Eastern Khanty dialect under analysis is heterogeneous and relatively vast. The controversy around the synthetic means of expression of semantic relations concerns the terminology of case markers, their quantity, morphemic status and functional features. The purpose of this paper is to clarify the functional and semantic aspects of the Vakh Khanty case markers drawing on the recently obtained field material. This objective is achieved by means of the tools available on the LingvoDoc platform. The latest field data on the Vakh Khanty dialect was collected in the village of Korliki in 2019. More than 6,000 words of data are posted on the endangered languages documentation platform LingvoDoc. Part of the material used in the analysis is being processed and integrated on the LingvoDoc platform. The underlying opinion of this study draws on the seminal work by N.I. Tereshkin, as well as other prominent researchers of the Khanty language, and their description of the declension system of the Eastern dialect. The latest field data contains texts and questionnaires allowing researches to examine functioning of the morphological markers and compare results with the findings previously presented in the literature. Such approach entails observations leading to the systematization of the case category in this dialect at its current state of development. The examination of the range of meanings conveyed by the Vakh Khanty case markers at present has made it possible to distribute them into groups of semantic and syntactic case markers. As a result, the study confirmed that the nominal declension system encompasses such case markers as the abessive, ablative, allative, distributive, comitative, comparative, lative, locative, nominative, oblicative, and translative cases. The recent field data confirms the presence of the distributive case within the case paradigm and the status of the comparative element niŋit as a postposition. Each case marker of the Vakh Khanty dialect is terminologically specified which is essential for developing a parser for this dialect on the LingvoDoc platform. The development of the parser in the future will speed up the process of processing and analyzing language material and lead to the elimination of errors.

The choice of an educational program is momentous in young people's lives. Given the shortage of time after exams, applicants usually do not have time to analyze possible educational tracks. Furthermore, it requires a thorough study of learning plans. This research addresses the problem proposing the algorithm to data-driven curriculum analysis based on natural language processing of course names or competences listed in learning plans. Moreover, the intelligent software system architecture is described. The method is tested on the curricula scraped from university websites. In order to store the content a data warehouse has been developed. At this time, there are few studies on this topic. The existing ones are either on the early stages of development or scarce on implementation details. They are briefly discussed in this paper.

Neoconidiobolus lachnodes (Drechsler) B. Huang & Y. Nie was originally isolated from plant debris in Florida, United States of America, in 1954. Here, we report the ﬁrst documented occurrence of N. lachnodes in central China. Morphologically, this fungus is characterized by its abundant aerial hyphae, typically arranged closely, with hyphae aggregating into chlamydospores during the later stages of growth. Phylogenetic analysis revealed that the N. lachnodes isolate from China (RCEF 7519) is closely related to the reference strain N. lachnodes (ARSEF 700). To elucidate the phylogenetic position of N. lachnodes within the Neoconidiobolus lineage, we included two nucleotide sequences of EFL and mtSSU loci. This discovery signiﬁcantly expands the known geographic distribution of N. lachnodes.
The interaction of tonal alignment with vowel length and syllable structure in Lebanese Arabic
Authors: Kelly Niamh E.
Published: August 2024

Research on a variety of languages has shown that tonal alignment in pitch accents can be influenced by segmental factors such as syllable structure, onset type, and phonological vowel length (e.g., Ladd et al., 2000; Maddieson, 1997). However, the majority of work on these topics has been on European languages. The current study examines the interaction of these factors in the Beirut dialect of Lebanese Arabic. Disyllabic words with initial, stressed syllables that were either open or closed and contained either a long or a short vowel and had a simple or complex onset were examined when non-focused and in contrastive focus. Contrastive focus was associated with a wider f0 range. The focus pitch accent was H* or L+H*. In terms of segmental effects, neither vowel length nor syllable structure had a significant effect on tonal alignment. Timing of the f0 peak was found to be consistently about 45 msec from vowel onset. This study contributes to the literature on tonal alignment by examining a variety of Arabic that is understudied in terms of intonation.

Published: August 2024

Background: Studies on communication partner training programs for persons with aphasia reveal improvements in the conversation partners’ communication skills. This article explores the strategies for topic maintenance developed by the conversational partners of three people with non-fluent aphasia before and after an intervention on conversational strategies. Method: We used conversation analysis to examine video-recorded samples of everyday conversations (pre- and post-treatment and follow-up) between three couples. The assessment for topic management was performed with Conversation Analysis Profile for People with Aphasia (CAPPA). The intervention was conducted over a period of five weeks. The partners were trained to use strategies for better topic maintenance (multiple-choice, multimodality, and message verification). At six weeks post-therapy, a third recording was made. Results: After the intervention, changes in topic maintenance were observed. The use of strategies is related to the pre-existing context and the presence of visual support. Discussion/Conclusion: Individuals with non-fluent aphasia and their conversation partners engage in multimodal conversations and benefit from the use of strategies to overcome barriers to understanding, leading them to maintain a conversational topic.

Machine learning (ML) is an artificial intelligence (AI) that enables computer systems to classify, cluster, identify, and analyze vast and complex sets of data while eliminating the need for explicit instructions and programming. For decades, machine learning has become helpful for complex reservoir characterization such as carbonate reservoirs. Permeability prediction from well logs is a significant challenge, especially when the core data is rarely available due to its high cost. In this study, we aimed to bridge this gap by demonstrating the practical application of integrating Hydraulic Flow Units (HFU) and machine learning methods. Our goal was to provide a reliable estimation of permeability using core and wireline logging data in the complex Middle Miocene carbonate reservoir of the CX gas field in the southern part of the Song Hong basin. In the first step, due to the reservoir’s heterogeneity, the core plug dataset was classified into 5 HFUs based on the flow zone indicators (FZI) concept from the modified Kozeny-Carman equation using unsupervised machine learning - K-means method. The porosity - permeability for each HFU was defined after HFU clustering. In the second step, we designed three different workflows to predict permeability and HFU using supervised machine learning from a combination of core and log data. These workflows were rigorously test and compared with the core data. The most accurate result was chosen as the base, providing a high confidence level in our predictions’ reliability.

The distribution of critical marine habitats in Quy Nhon Bay, Binh Dinh Province, was assessed with the combination of resolution of Google Earth images and local knowledge through local consultations and ground truthing using small boats to check the sites supporting coral reefs and seagrass beds with local involvement. Detailed surveys on species diversity and conditions of marine habitats were conducted at 24 sites of coral reefs and four sites of seagrass beds at three sites (Nhon Ly, Nhon Hai, Ghenh Rang, and Nhon Chau) in 2016–2017. More than 152 ha of coral reefs, 5 ha of seagrass beds, and 720 species belonging to 7 key groups (290 species of fishes; reef-building corals: 194, molluscs: 123, seaweeds: 47, echinoderms: 40, crustaceans: 20 and seagrasses: 6 species) associated with the above habitats were recorded in the Bay. Among them, 92 species were facing different threats, in which 3 species were endangered (EN), including branching corals (Alveopora minuta), flat pen shells (Atrina vexillum), and top shells (Tectus pyramis); 38 species at vulnerable (VU); and 51 species at near threatened (NT) following the IUCN Red List and Vietnam Red Book. In general, the coral reefs and seagrass beds at Bai Dua and Seo Island (Nhon Ly); Kho Nho Island, Bo Dap (Nhon Hai); S. Ngang Island, Bai Nam and Bai Nom of Dat Island (Ghenh Rang); Da Ban, Bai Lang, Bai Lang Ba and Ong Gia Island (Nhon Chau) supported higher diversity and better conditions than other sites. Establishing restricted zones at these sites is an urgent need, but it also holds the premise of sustainable utilization and conservation of resources in the future.
