Authors: В. И. Фандюшин  , Н. Н. Пудич  , Ю. В. Улихина
Published: October 2024

В данной статье представлена структурная схема адаптивного регулятора мощности дуговых сталеплавильных печей. Широкие исследования эксплуатации таких печей показали, что существует много факторов, приводящих к повышенной дисперсии колебаний тока дуги, а это в свою очередь вызывает неравномерность выделения мощности и снижает технико-экономические показатели печи. Поэтому является актуальной задача адаптации системы автоматического регулирования мощности дуговых сталеплавильных печей к изменяющимся характеристикам возмущающих воздействий по ходу плавки. От повышенной дисперсии колебаний тока дуги можно избавиться путём адаптации параметров регулятора мощности к определённому типу возмущений, появляющихся в металлургические периоды плавки. В другие периоды плавки, например, в режиме расплавления твёрдой шихты такая адаптация невозможна и даже вредна. Снизить колебания токов дуг можно путём изменения инерционности цепи управления в зависимости от номера ступени переключателя ступеней напряжения печного трансформатора. Инерционность цепи управления предложено регулировать вводом в цепь апериодического звена первого порядка. В статье описана разработка адаптивного контура регулирования положения электрода, даны рекомендации по используемым электронным компонентам и представлены возможности дальнейшей модернизации системы управления. Ключевые слова: дуговые сталеплавильные печи, регулятор мощности, апериодическое звено, периоды плавки, адаптация.

Повышение энергоэффективности является одним из ключевых способов обеспечения перехода техногенной деятельности человека к низкоуглеродной экономике. Тепловая изоляция является эффективной мерой по снижению потерь тепла, что, в свою очередь, способствует сокращению выбросов загрязняющих веществ и парниковых газов. В настоящее время проектирование тепловой изоляции теплотехнического оборудования в Казахстане осуществляется на основе методов, которые изложены в строительных нормах и правилах: МСН 4.02-03-2004 и СП РК 4.02-102-2012. В представленной статье указаны основные принципы применения действующих нормативных методов. В ходе анализа указанных регламентирующих документов было установлено, что для теплотрасс, проложенных под землей, ключевые параметры проектирования задаются суммарно для подающего и обратного трубопровода. В связи с данным обстоятельством не представляется возможным произвести расчет толщины тепловой изоляции для каждого из указанных трубопроводов по отдельности. Это является методологическим недостатком нормативных документов. Для оценки рациональности расчета тепловой изоляции на основе регламентирующих документов в статье рассмотрены конкретные примеры его применения и выполнен анализ на основе чистого приведенного эффекта инвестиций. Материалы, изложенные в данной статье, показывают, что проектирование тепловой изоляции по действующим нормативным документам не обеспечивает выявление оптимальных параметров теплоизоляционного слоя. В связи с этим возникает потребность в необходимости разработки альтернативного подхода для решения данной проблемы. Ключевые слова: нормы проектирования, тепловая изоляция, энергосбережение, тепловые потери, экономическая оценка.

Published: October 2024

La relevancia de la ópera de Sídney trasciende su arquitectura para convertirse tanto en frecuente cita como en recurrente fuente de estudio y testimonio de las convulsiones de la profesión a partir de la segunda mitad del siglo XX. Como toda gran obra de arquitectura, depositaria del conocimiento de la disciplina, su relectura desde otra época alumbra nuevos matices al tamiz de un presente huérfano de referentes. Este texto propone revisitar tanto la obra como su proceso de realización para sugerir apuntes superpuestos a este palimpsesto de consideraciones como pueden ser la conexión con la naturaleza y la vida, el subsiguiente renacimiento de la forma, el recurso velado a la repetición y la geometría, o en otro registro, el compromiso profesional y técnico, la multidisciplinariedad como condición y una crítica a las prácticas neoliberales actuales. El ámbito de la reflexión se sitúa en el vaivén entre lo universal, discurriendo por principios disciplinares más ambiguos y contradictorios de lo que pudiera parecer, y lo local, infiltrándose discretamente en la cultura arquitectónica de numerosas prácticas actuales como la que recoge este número de la revista.

Bir Dönüşümün Arkeolojisi: Kayıkçı Parası
Authors: Okumuş Salih
Published: October 2024

Durali Yılmaz’ın son kitabı “Köprüler Kurmak Sonsuza” adlı eserinde yer alan “Kayıkçı Parası” Avrupalıların ülkemizde yaptığı arkeolojik kazılara farklı bir bakış sunarak dikkatlerimizi çeker. Fransız inkılabıyla Avrupa’da baş gösteren milliyetçilik fikrini de tetikler. Kendisini Avrupa halklarının atası gören uluslar da güncel bir tarih tezi oluşturma peşine düşerler. Bu konuda başı çeken Almanlar, Homeros’un destanlarında anlatılan Truva’ya yönelip Çanakkale’de arkeolojik kazılara başlar. Bu kazılar için son olarak bölgeye gelen ünlü Alman arkeolog ve bilim adamı Manfred Korfmann’dır. Korfmann kazılar dışında yerel halkla yakından ilgilenir, kahveye gider ve Türkçe öğrenir. Bilhassa Türk müziğine hayran kalır. Bundan sonra hikâye adeta kendisine ulu bir ata arayan Korfmann’ın Anadolu coğrafyasında yaptığı içsel yolculuğa dönüşür. Bu yolculuk medeniyetler beşiği olarak gördüğü Anadolu’dan Truva’ya kadar uzanır. Yazar, Korfmann’ı bu yolculuk sırasında isminden başlayarak dil, tarih ve kültür bağlamında dönüştürür ve karşımıza bambaşka bir kimlikte yeni bir insan çıkarır. Bu dönüşüm Truva’dan Troya’ya ulaşarak mekânsal bir boyut da kazanır. Bu çalışmada, Durali Yılmaz’ın Köprüler Kurmak Sonsuza adlı son eserinde yer alan “Kayıkçı Parası” adlı hikâyesini insan ve mekân dönüşümü açısından analiz edilmiştir.

Short vs Standard Duration Dual Antiplatelet Therapy after Percutaneous Coronary Intervention with New-Generation Drug-Eluting Stents: A Meta- Analysis
Authors: Ullah Inam , Muhammad Muhammad Afaq , Muhammad Haidar Zaman  , Khan Umair Khan
Published: October 2024

Objective: In patients with coronary artery disease, dual antiplatelet therapy (DAPT) is recommended after percutaneous coronaryintervention, but the duration is still debated. This meta-analysis compared short-duration (1 to 3 months) to standard-time (twelve months) double antiplatelet treatment in patients who received coronary intervention with new generation drug eluting Stent.Methodology: To conduct this examination, we methodically looked at PubMed, Cochrane CENTRAL, Embase, and Web of Sciencedatabases for randomized controlled trials, evaluating varying durations of double antiplatelet treatment following new generation stents implantation from July to September 2023. Seven randomized controlled trials were included with a total of 22,945 patients. The primary efficacy endpoint was the incidence of Major adverse cardiovascular events, such as cardiac mortality, heart attack, stent coagulation, and target vessel revascularization; while the safety endpoint was the incidence major bleeding. Secondary endpoints were major adverse cardiovascular and cerebro-vascular complications, any bleeding, and net adverse cardiovascular incidence for a year after stent implantation.Results: Short-time DAPT was linked to a significantly less incidence of major bleeding (0.8% vs 1.5%), any bleeding (2.5% vs 4.2%)and NACE (2.5% vs 4.2%) compared to standard duration of DAPT. No significant variation was noticed among the two groups regarding major adverse cardiovascular events (4.1% vs. 4.2%) and acute cardiovascular and cerebrovascular incidents (4.7% vs. 4.8%). Short-duration DAPT in patients with acute coronary syndrome was linked with decreased risk of bleeding and net adverse cardiovascular events.Conclusion: Short-duration DAPT significantly lowers bleeding risk and reduces net clinical adverse events without increasing ischemic risk, making it a reasonable choice for people with new-generation drug eluting stents, particularly those with highbleeding risk or recent surgery.
An LES Exploration of the Assumptions used in Retrieving Entrainment from a Mixing Diagram Approach with Ground-Based Remote Sensors
Authors: Rosenberger Tessa E. , Heus Thijs , Raghunathan Girish N. , Turner David D. , Wagner Timothy J. , Simonson Julia M.
Published: October 2024

Abstract. Entrainment is a crucial component of the atmospheric boundary layer (BL) moisture and heat budget. While usually thought of as only entrainment flux, entrainment within the mixed layer budget equation is really composed of two terms: the flux of a property across the boundary separating the BL from the free troposphere and the change in the concentration of a property as the depth of the BL changes. In a recent study, Wakefield et al. (2023) used ground-based remote sensing observations to estimate entrainment flux as the residual of a mixing diagram framework that was applied to the daytime convective boundary layer. This present work uses LES to examine how well this residual assumption for entrainment fluxes alone compares to the actual sum of those two entrainment terms derived from spatial averages of the LES output. We highlight the importance of the second entrainment term in closing the mixed layer budget and show that the residual assumption does not represent entrainment flux only but rather a total entrainment term when the boundary layer depth is changing.
Effects of sudden stratospheric warmings on the global ionospheric total electron content using a machine learning analysis
Authors: Ma Guanyi , Hocke Klemens
Published: October 2024

Abstract. A sudden stratospheric warming is a breakdown of winter stratospheric polar vortex. It has atmospheric effects in both the Northern and Southern hemispheres, leading to disturbances in the whole ionosphere. Previous works with case studies have shown that SSW effect is mainly in low-latitude ionosphere and each SSW event may have a different effect on the ionosphere due to complex dynamics from solar/geomagnetic activities and seasonal changes. However, the SSW induced tidal variability in mid to high-latitude ionosphere is only identified for several events and its behaviour is not well understood. Here we analyze SSWs’ influences on diurnal/semidiurnal variations of global ionosphere with the global maps of total electron content (TEC) from 1998 to 2022. We use machine learning (ML) with neural network to establish the TEC (ML-TEC) model related to the solar/geomagnetic activities and seasonal change from the long-term global TEC data. The TEC variations due to SSWs are extracted by subtracting the ML-TEC from the observed TEC. Comprehensive composite analysis of 18 SSW events shows for the first time a globally SSW-induced enhancement in diurnal/semidiurnal TEC variations. The enhancement is the strongest at equatorial ionospheric anomaly (EIA) crests, moderate in mid-latitude and vague in high-latitude ionosphere. It also exhibits hemispheric asymmetry and longitudinal differences. While the semidiurnal enhancement starts earlier and peaks at ~8 days after SSW onset, the diurnal one starts on the SSW onset day and peaks around 20–30 days after SSW onset. The enhancement of both semidiurnal and diurnal TEC variations lasts to about 50 days after SSW onset. The SSW related E-region dynamo is likely the dominant mechanism which is not strong enough to produce discernible TEC variations in high-latitude ionosphere. ML-TEC does not contain the SSW effect and is thus a valuable reference for the ionospheric state without an SSW.
Informativeness of teleconnections in local and regional frequency analysis of rainfall extremes
Authors: Magnini Andrea , Pavan Valentina , Castellarin Attilio
Published: October 2024

Abstract. We propose an effective and reproducible framework to assess the informative content of teleconnections for representing and modeling the frequency regime of rainfall extremes at regional scale. Our dataset consists of 680 annual maximum series of rainfall depth, with 1 and 24 hours durations, located in northern Italy. We compute at-site time series of L-moments through sliding time windows; then we discretize the study region into tiles, where L-moments time series are averaged. We observe that the Western Mediterranean Oscillation index (WeMOI) shows strong spatial correlation patterns with gridded L-moments. Finally, in a preliminary application of climate-informed regional frequency analysis, the L-moments are modelled as functions of WeMOI. We observe high variability of WeMOI-driven rainfall percentiles predictions, and an increase in overall goodness-of-fit of the regional model relative to the stationary framework. Overall, our research suggests promising pathways for climate-informed local and regional frequency analysis of rainfall extremes, and describes general methods, that can be adapted to different environmental variables.

Published: October 2024

O caracteristică importantă a capacităţii de învăţare o reprezintă receptivitatea elevului faţă de asimilarea conţinutului informaţional, capacitatea de interpretare a acestor informații şi dezvoltarea competențelor pe baza cunoştinţelor însuşite pentru rezolvarea unor probleme/situații similare. Sub aspectul domeniului somato-psihic, elevul trebuie să dispună de o stare de sănătate optimă vârstei, integritate senzorială şi dezvoltare fizică armonioasă. Dacă aceste cerințe nu sunt respectate, apar o serie de manifestări nedorite, dintre care cel mai frecvent observate sunt: agitaţia psihomotrice, atenţia deficitară, oboseala, capacitatea redusă de îndeplinire a obiectivelor şcolare. Scopul prezentei cercetări este acela de a interveni în procesul instructiv – educativ pentru ca aceste probleme să nu se amplifice odată cu trecerea elevului în clasele superioare. De aceea, am încercat să aflăm dacă, acționând în sensul dezvoltării capacităților coordinative, putem influența rezultatele școlare anuale ale elevilor sub aspectul îmbunătățirii acestora

Published: October 2024

Obezitatea este una dintre cele mai răspândite boli cronice din lume și atinge proporțiile unei epidemii. Conform datelor Organizaţiei Mondiale a Sănătăţii (OMS,) numărul copiilor obezi se dublează la fiecare trei decenii. Obezitatea infantilă este un factor major în dezvoltarea ulterioară a multor boli somatice grave, precum: diabetului zaharat de tip 2, cardiopatia ischemică, boala hipertensivă, astm bronşic şi unele forme de cancer. Aceste boli sunt în prezent principalele cauze de deces anual a peste 2,5 milioane de oameni din ţările industrializate. Astfel, prevenirea timpurie a supraponderabilităţii şi obezităţii în copilărie este o prioritate în îngrijirea sănătăţii unei populaţii. Factorii-cheie, care favorizează dezvoltarea supraponderabilităţii şi obezităţii în copilărie, sunt alimentaţia hipercalorică şi insuficienţa de activitate fizică. Studiul prezent este dedicat analizei rezultatelor înregistrate în baza chestionarelor alimentar şi de evaluare a activităţii fizice a elevilor din ciclul primar cu vârsta de 8 – 9 ani. Sunt discutate recomandările practice concrete de prevenţie a supraponderabilităţii, nutriţiei raţionale, activităţii fizice în educarea unui mod de viaţă sănătos a populaţiei de vârstă şcolară mică.

A comparative analysis of thermoelastic characteristics of ceramic matrix composite materials (CMC) obtained by liquid and gas phase technologies, reinforced with two types of carbon fibers (CF), is carried out based on different model structural phase composition of the obtained matrix material. It is noted that when implementing the liquid phase siliconizing and using high modulus carbon fibers with high negative values of the absolute value of the coefficients of linear thermal expansion (CLTE), a simplified model of the matrix material consisting of only one SiC phase can be correctly used. When implementing PIP and CVI technologies, CMC with low modulus CF and CF with low negative CLTE values show the greatest sensitivity to an increase in matrix porosity. For CMC based on CF T800, the change in the longitudinal CLTE was about 66% with a porosity of 20%. An increase in porosity leads to a decrease in all elastic characteristics of the CMC, to the greatest extent for the transverse modulus of elasticity and the shear modulus.

Method of the optimal cutoff frequency determination for signal estimatiоn by its measurements
Authors:   Gromov Flight Research Institute, Grigoriev N. V.
Published: October 2024

A typical procedure for flight test data processing is the measurements smoothing to obtain the estimate of the true signal measured in flight. If the data processing is carried out in the frequency domain, it becomes necessary to estimate the frequency transform (Fourier transform) of the true signal by its measurements. A method is proposed for constructing the simplest estimate of the signal Fourier transform in the form of the low frequency part of the Fourier transform measurements. Such estimate is determined by the single parameter – the cutoff frequency. The indicator for the estimate quality is the mean square of its deviation from the Fourier transform of the true signal. The task of constructing the estimate of the signal Fourier transform is considered as the task of finding the optimal cutoff frequency for which the criterion is minimal. An approximation of the criterion dependence on the cutoff frequency is constructed as the function of measurements only. The estimate of the optimal cutoff frequency is found by minimizing the approximation dependence. The proposed method for estimating the optimal cutoff frequency does not contain adjustable parameters. In the application to the tasks of identifying aircraft aerodynamic characteristics, it is shown that estimates of cutoff frequencies obtained by the proposed method provide identification accuracy comparable to the identification accuracy at optimal cutoff frequencies.
Muma-Pădurii: the mythological dimension and its role in the traditional collective mind
Authors: Niţă-Cocieru Mariana
Published: October 2024

In this article, the author explores the mythological and folkloric dimension of the deity Muma-Pădurii, one of the most complex and contradictory archetypal figures in traditional collective mentality. Muma-Pădurii symbolizes both primordial fears related to nature and the duality between good and evil. Although predominantly described in popular beliefs and superstitions as a malevolent and terrifying character capable of causing harm and destruction, she also exhibits a compassionate and protective side, often being pacified by the kindness of fairy tale heroes. With pre-Christian roots and considered a maternal deity governing the wild nature, Muma-Pădurii is part of an extensive pantheon of spirits and deities associated with the elements and the forest, alongside other mythological entities such as Fata-Pădurii and Moșul Codrului. Although initially a protector of the forest and its inhabitants, during the Christian period, she acquired a malevolent character, becoming an entity associated with evil spirits. In traditional collective mentality, Muma-Pădurii is described as a monstrous and terrifying being, who punishes those who break the rules of the forest, becoming a symbol of the wild and obscure forces of nature. In some folkloric creations, she serves as a comparison for people with an ugly appearance and a petty soul.
The Romanization of Anglicisms
Authors: Căruntu-Caraman Livia
Published: October 2024

The adoption of Anglicisms in communication was justified by the usefulness of designating new extra-linguistic realities from various fields of activity, resulting in an obvious enrichment of the vocabulary of the Romanian language. Many of the terms, especially those introduced from the beginning, have adapted perfectly phonetically and graphically and are used in the active lexicon, so that most of them are no longer aware of their English origin, acquiring full rights to be considered units of the Romanian language (aisberg, cip, clovn, fotbal, hochei, lider, pulover, meci, miting, seif, trenci, trening). At the current stage, a number of anglicisms occur, especially in the online environment, in an adapted orthographic form. This fact motivated us to approach in this article also the degree of graphic assimilation presented by some Anglicisms, with a frequent circulation in use, registered or not in the lexicographic works. At the same time, we are trying, more or less forced, to establish some models of Romanian writing of Anglicisms necessary in communication
Reading and Writing Research Based on Surname Group
Authors: Liu Jiexuan
Published: October 2024

This study examines the influence of surname on academic performance in higher education. It includes an in-depth analysis of comprehensive book circulation data from the library of Nanjing Normal University, covering the period from 2012 to 2023. The study uses Kendall coefficients to assess the consistency in book circulation and renewal among the top 300 surnames of readers, employs multidimensional scaling analysis to identify differences or similarities between categorical variables through direct distance assessment, uses chi-square tests to measure the correlation between surnames above and below the mean line and various categorical variables, and conducts survival analysis to examine circulation activities related to the top 300 surnames. Results are interpreted in the context of female-dominated education and teacher preparation. The results reveal a consistent pattern in the 12-year borrowing and renewal habits of the top 300 surnames of readers. A hierachical mismatch between the reader, book category, and author reflects complex reading interests beyond academic authority. In the wake of the COVID-19 pandemic, readers with surnames above the average have shown less interest in using the book renewal service. The borrowing and renewal activity for the disappeared surnames changed within two years for foreign language books and six years for Chinese books.
Hypsometric Analysis and Tectonic Activity Evaluation in the Semangko Fault Zone: A Literature Review
Authors: Gultaf Hikhmadhan
Published: October 2024

This comprehensive review synthesizes and analyzes current literature on hypsometric analysis and its application in evaluating tectonic activity within the Semangko Fault Zone, a critical segment of the Sumatran Fault system. The study examines how hypsometric curves (HC) and hypsometric integrals (HI) serve as quantitative indicators of landscape evolution and tectonic deformation. By critically analyzing existing research, this review highlights the strong correlation between high HI values and areas of active tectonic uplift within the fault zone. The paper also explores the integration of hypsometric analysis with other geomorphic indices and its potential in seismic hazard assessment. Our findings underscore the significance of hypsometric analysis as a valuable tool in understanding the complex tectonic processes shaping the Semangko Fault Zone and its implications for regional seismic risk evaluation and land-use planning.
