Published: April 2024

Abstract. We describe an idealized Southern Ocean model (ISOM 1.0) that contains simplified iconic topographic features in the Southern Ocean and conduct a fully mesoscale-resolving (2 km) simulation based on the Massachusetts Institute of Technology general circulation model (MITgcm). The model obtains a fully developed and vigorous mesoscale eddying field with a k-3 eddy kinetic energy (EKE) spectrum and captures the topographic effect on stratification and large-scale flow. To make a more naturally conceptual introduction of large eddy simulation (LES) methods into ocean mesoscale parameterization, we propose the concept of mesoscale ocean direct numerical simulation (MODNS). A qualified MODNS dataset should resolve the first baroclinic deformation radius and ensure that the affected scales by the dissipation schemes are sufficiently smaller than the radius. Such datasets can serve as the benchmark for a priori and a posteriori tests of LES schemes or mesoscale ocean large eddy simulation (MOLES) methods into ocean general circulation models (OGCMs). The 2 km idealized simulation meets the requirement of MODNS and also captures part of the submesoscale processes. Therefore, its output can be a type of MODNS and provide reliable data support for relevant a priori and a posteriori tests. We also illustrate the diversity and high complexity of multiscale eddy interactions related to mesoscale processes. We emphasize the importance of submesoscale phenomena on the evolution of mesoscale processes when mesoscale activities are vigorous and of high eddy number density. In addition, we use the model to conduct multipassive tracer experiments and reveal guidelines for the initial settings of passive tracers to delay the homogenization process and ensure the mutual independence of tracers over a long period.

Published: April 2024

Abstract. This study presents a probabilistic model that partitions the precipitation phase based on hourly measurements from a network of radar-based disdrometers in eastern Canada. The network consists of 27 meteorological stations located in a boreal climate for the years 2020–2023. Precipitation phase observations showed a 2-m air temperature interval between 0–4 °C where probabilities of occurrence of solid, liquid, or mixed precipitation significantly overlapped. Single-phase precipitation was also found to occur more frequently than mixed-phase precipitation. Probabilistic phase-guided partitioning (PGP) models of increasing complexity using random forest algorithms were developed. The PGP models classified the precipitation phase and partitioned the precipitation accordingly into solid and liquid amounts. PGP_basic is based on 2-m air temperature and site elevation, while PGP_hydromet integrates relative humidity. PGP_full includes all the above data plus atmospheric reanalysis data. The PGP models were compared to benchmark precipitation phase partitioning methods. These included a single temperature threshold model set at 1.5 °C, a linear transition model with dual temperature thresholds of –0.38 and 5 °C, and a psychrometric balance model. Among the benchmark models, the single temperature threshold had the best classification performance (F1 score of 0.74) due to a low count of mixed-phase events. The other benchmark models tended to over-predict mixed-phase precipitation in order to decrease partitioning error. All PGP models showed significant phase classification improvement by reproducing the observed overlapping precipitation phases based on 2-m air temperature. PGP_hydromet and PGP_full displayed the best classification performance (F1 score of 0.84). In terms of partitioning error, PGP_full had the lowest RMSE (0.27 mm) and the least variability in performance. The RMSE of the single temperature threshold model was the highest (0.40 mm) and showed the greatest performance variability. An input variable importance analysis revealed that the additional data used in the more complex PGP models mainly improved mixed-phase precipitation prediction. The improvement of mixed-phase prediction remains a challenge. Relative humidity was deemed the least important input variable used, due to consistent near water vapor saturation conditions. Additionally, the reanalysis atmospheric data proved to be an important factor to increase the robustness of the partitioning process. This study establishes a basis for integrating automated phase observations into a hydrometeorological observation network and developing probabilistic precipitation phase models.
Fractal analysis of geomagnetic data to decipher pre-earthquake process in Andaman-Nicobar region, India
Authors: Prajapati Rahul , Arora Kusumita
Published: April 2024

Abstract. The emission of seismo-electromagnetic (EM) signatures prior to earthquake recorded in geomagnetic data has potential to reveal the pre-earthquake processes in focal zones. This study focused to analysis of vertical component of a geomagnetic field from Mar 2019 to Apr 2020 using fractal and multifractal approach to identify the EM signatures in Campbell Bay, a seismically active region of Andaman and Nicobar, subduction zone. The significant enhancements in monofractal dimension and spectrum width components of multifractal highlights the high frequency with less and more complex nature of EM signatures preceded by earthquakes respectively, which indicates that the pre-earthquake processes on West Andaman Fault (WAF) and Andaman Trench (AT) are due to micro fracturing. Moreover, the significant enhancements in holder exponents, components of multifractal highlight the less correlated, smooth, and low frequency characteristics of EM signatures preceded by earthquakes, which indicate that pre-earthquake processes on Seulimeum Strand (SS) fault are due to electrokinetic processes. Thus, the mono fractal, spectrum width, and holder exponent parameter respond differently to the earthquakes with different characteristics, causing EM signatures to be observed with an average of 10, 12, and 20 days prior to the earthquakes respectively, which are also lies in range of short -term earthquake prediction.
Control co-design optimization of floating offshore wind turbines with tuned liquid multi-column dampers
Authors: Yu Wei , Zhou Sheng Tao , Lemmer Frank , Cheng Po Wen
Published: April 2024

Abstract. The technical progress in the development and industrialization of floating offshore wind turbines (FOWTs) over the past decade has been significant. Yet, the higher levelized cost of energy (LCOE) of FOWTs compared to onshore wind turbines is still limiting the market share. One of the reasons for this is the larger motions and loads caused by the rough environmental excitations. Many prototype projects tend to employ more conservative substructure designs to meet the requirements for motion dynamics and structural safety. Another challenge lies in the multidisciplinary nature of a FOWT system, which consists of several strongly coupled subsystems. If these subsystems cannot work in synergy, the overall system performance may not be optimized. Previous research has shown that a well-designed blade pitch controller is able to reduce the motions and structural loads of FOWTs. Nevertheless, due to the negative aerodynamic damping effect, improvement in the performance by tuning the controller is limited. One of the solutions is adding tuned liquid multi-column dampers (TLMCDs), meaning that there is a structural solution to mitigate this limiting factor for the controller performance. It has been found that the additional damping, provided by TLMCDs, is able to improve the platform pitch stability, which allows a larger blade pitch controller bandwidth and thus a better dynamic response. However, if a TLMCD is not designed with the whole FOWT system dynamics taken into account, it may even deteriorate the overall performance. Essentially, an integrated optimization of these subsystems is needed. For this paper, we develop a control co-design optimization framework for FOWTs installed with TLMCDs. Using the multi-objective optimizer non-dominated sorting genetic algorithm II (NSGA-II), the objective is to optimize the platform, the blade pitch controller, and the TLMCD simultaneously. Five free variables characterizing these subsystems are selected, and the objective function includes the FOWT's volume of displaced water (displacement) and several motion and load indicators. Instead of searching for a unique optimal design, an optimal Pareto surface of the defined objectives is determined. It has been found that the optimization is able to improve the dynamic performance of the FOWT, which is quantified by motions and loads, when the displacement remains similar. On the other hand, if motions and loads are constant, the displacement of the FOWT can be reduced, which is an important indication of lower manufacturing, transportation, and installation costs. In conclusion, this work demonstrates the potential of advanced technologies such as TLMCDs to advance FOWTs for commercial competitiveness.

Published: April 2024

This article discusses the theoretical and legal aspects of environmental damage compensation. In the Republic of Kazakhstan, the right of everyone to live in a favorable environment has been constitutionally enshrined. This indicates that it is necessary to ensure the environmental safety of not only one state, but also the state on which the well-being of the whole world depends. But practice shows that the state of the environment is alarming every year. For example, the state of soil and soil deterioration. Currently, compensation for environmental damage is one of the urgent problems of environmental law. Ensuring the ecological safety of the country largely depends on the unfavorable state of the environment. There are quite serious environmental problems affecting the state of the environment. From this point of view, consideration of theoretical and legal aspects of environmental damage compensation and specific proposals aimed at improving legislation in this area are of great importance. This article provides an in-depth analysis of the legal norms concerning environmental harm and environmental damage in the environmental legislation of the Republic of Kazakhstan. It is also noted that the issues of environmental damage should be considered from the point of view of the inseparable and organic connection of the social, environmental and economic goals of the country. In conclusion of this article, the author points out that one of the necessary conditions for compensation for damage caused by violation of environmental legislation is the elimination of contradictions between environmental and civil legislation.

Feminist Arrivals: The Arc of Refusal and the Right to (Leave) the City
Authors: Gebhardt Mareike
Published: April 2024

The paper discusses the three stations of an arc of refusal elaborated in Bonnie Honig’s recent book A Feminist Theory of Refusal (2021). Asking why a feminist refusal needs to return to the city, the paper claims a right to leave the city without returning. The critique reads Honig’s recent book in the light of former publications, especially Honig’s Political Theory and the Displacement of Politics from 1993. It shows how a thinking of the ambivalence between settlement and unsettlement shapes Honig’s works throughout the years which we also find in the recent book on feminist refusal – a refusal that unsettles the city’s infrastructures, beliefs, ideas, and figurations of settlement and security. With and against Honig’s theory of refusal, I argue that refusal provides a feminist tool to question the privileges of settlement. However, refusals and refusers do not need to return to the city to qualify as feminist.
Return to the City to Claim It: Temporalities and Locations of Feminist Refusal
Authors: Koekoek Catherine
Published: April 2024

One of the main contributions of A Feminist Theory of Refusal is its connection of everyday action and prefigurative practices with an explicit commitment to structural change. But how such change happens, and what kind of relations it implies between ‘the city’ (as the existing political community) and feminist heterotopias of refusal, remains unclear. Reading Honig’s work as a prefigurative theory, I argue that it links moments of doing-otherwise with moments of institutional politics, sparking questions about the conditions of a successful return to the city. I then develop these conditions through a case study of the feminist activism of Women on Waves; and argue that feminist refusal can lead to political transformation if it durably connects practices inside and outside the city.
Inoperativity as a form of Refusal: On Bonnie Honig’s Reading of Agamben
Authors: Primera German
Published: April 2024

The aim of this article is to follow Honig's intention of thinking inoperativity as a form of refusal. It demonstrates that Agamben's inoperativity entails an intensification of use that can circumvent the pitfalls associated with the language of 'demands,' or the need to rescue the city as the space of the political par excellence, all while preserving its potential for instituting change. I claim that all destitution entails instituting practices and forms of experimentation that modify the subject, and that, with the help of Agamben, subjects are nothing other than these modifications. The wager of this short intervention, therefore, is that a form of refusal that pays critical attention not only to the suspension but also to the intensification of use that this suspension inherently entails is attainable, all while acknowledging that the city is shaped by anti-blackness.

Published: April 2024

Concentrated Solar Thermal (CST) systems emerge as a promising alternative to replace fossil fuels used in industrial thermal processes due to their high energy density and dispatchability. In this study, a comparative analysis of two CST systems, Solar Tower (ST) and Parabolic Trough Collector (PTC), has been made to replace natural gas used in the steam generation process in Türkiye's largest steel production plant, located in the Mediterranean Region of Türkiye. Both the ST and PTC systems were placed in a field area of approximately 0.4 km2. The results have shown that, on a monthly basis, the PTC system could exceed the plant's thermal energy for two-thirds of the year, while the ST system could meet the plant's energy requirements for one-third of the year. This could reduce CO2 by about 12.7 and 19.1 kilo-tones for ST and PTC at LCOH of about 68.9 and 36.9 EUR/MWh, respectively.

Published: April 2024

This research is motivated by the reality that da'wah activities have penetrated into the cells of society. Not only in cities, da'wah has reached the pores of village communities far from urban areas. The esoteric model of preaching or the ethical model looks for its own place to adapt to the dynamics of its own society. Dai as a da'wah actor metamorphoses into the atmosphere of the object of his da'wah to make an invitation, he really merges into one, in the same spiritual atmosphere as the object of his da'wah, the preacher's activities in society carry out a transformation of Islamic values   so that community cohesion is built strongly. In the real picture in the Sombomerten community, Islam is embraced and practiced without any complaints at all and the community enjoys Islamic values   as an identity. The question arises as to how da'wah activities can build the cohesiveness of the Muslim community in Sombomerten Yogyakarta.The research method used is in-depth interviews, where the researcher really conducts interviews in detail, including making observations, observations which are carried out by participant observation and are truly involved in community activities.The results of the research show that da'wah activities have become a daily activity for residents, every day residents perform congregational prayers at the Nurul Muttaqin Mosque, every week for men the Friday prayer is mandatory to listen to the sermon, on Sunday nights there is mujahadah, especially in the month of Ramadlan there is takjilan accompanied by lectures before breaking the fast, the evenings of tarawih and tadarusan, the annual da'wah activities include Eid al-Fitr and Eid al-Adha. The second moment of this holiday becomes a medium of friendship for all residents because those who usually don't go to the mosque all go to the mosque for friendship. Temporary activities such as commemorating Islamic holidays such as the Prophet's birthday and social activities such as community service and tahlilan. Nearly all Sombomerten children are instilled in Islam from an early age through AEC.

Authors: Gu Xiaoxia , Hassan Norlizah Che , Sulaiman Tajularipin
Published: April 2024

With the rapid development of China, parents are placing higher and higher expectations on their children’s education. Drawing upon baseline data from the China Education Panel Survey (CEPS2013), this study delves into the mechanisms through which the learning attitude of junior high school students affects the association between parental educational expectations and academic performance. The results of the present study show that students’ learning attitude is a significant factor that impacts the academic performance of junior high school students and plays a substantial mediating role in the relationship between parental educational expectations and academic performance. Our analyses reveal that parental educational expectations have a greater impact on test scores compared to cognitive ability. Additionally, the mediating effect of learning attitude on the relationship between parental educational expectations and test scores is considerably stronger than the relationship between parental educational expectations and cognitive ability. These results contribute to a better understanding of the mechanism by which parental educational expectations affect children’s academic performance, which has implications for educational policy and practice in China.

Contribution To the Evaluation of Soot Deposit Thickness Evolution and Its Impact on Heat Transfer Within Heavy Diesel Engines: An Innovative Simplistic Procedure
Authors: Rahim Abdelhamid , Hemmouche Larbi , Beniaiche A. , Liazid Abdelkrim
Published: April 2024

This study deals with a numerical procedure designed and built to evaluate the evolution of soot deposits thickness and their impact on heat transfer for a high-pressure common rail 16V280 marine diesel engine piston. Using a combination of 3D numerical computations and an iterative calculation algorithm, this work reveals the complex relationship between soot deposit, temperature distribution, and piston thermal dynamics. Non-uniform soot deposit distribution is observed, concentrated at the piston bowl peripheral regions. This distribution aligns with theoretical expectations, indicating the influence of the swirl effect. The presence of soot deposits alters the temperature distribution, implying displacement of high-temperature zones towards the bowl region of the piston. The reduction in surface temperature of approximately 14%, is attributed to the lower heat transfer coefficient of deposited layers. This greatly influences the distribution of thermo-mechanical stresses of the piston. The proposed procedure offers an approach to assess the impact of soot deposit on heat transfer. In addition, this study contributes to a better understanding of realistic piston conditions and addresses the challenges introduced by soot deposits in heavy-duty diesel engines by combining the proposed procedure with investigations based on CFD software tools.

Published: April 2024

Urinary tract infections (UTIs) are a major public health concern causing mortality and morbidity worldwide. There are approximately 13,000 deaths that are linked to UTIs every year. Bacterial antibiotic resistance is increasing globally, making it difficult to treat urinary tract infections. Biochemical tests have resulted in inaccurate identification, due to which wrong empirical treatment of antibiotics is prescribed. The present research work aims to identify rare bacterial isolates along with the assessment of antibiotic resistance patterns. A total of 339 samples were examined for urine cultures. Based on biochemical testing, three positive samples were selected. Culture sensitivity results revealed two multidrug-resistant and one extensively drug-resistant bacteria. MDR strains showed sensitivity to meropenem, gentamicin, cefoperazone-sulbactam, nitrofurantoin, tigecycline and imipenem, and co-amoxiclav while XDR bacteria showed sensitivity to nitrofurantoin and tigecycline. The 16S rRNA sequencing results revealed two Escherichia fergusonii strains and one Morganella morganii strain. Our findings revealed the identification of rare and opportunistic bacteria less reported from Pakistan. In addition, it is the first report of E. fergusonii from Pakistan. In conclusion, using molecular identification of rare and neglected bacteria via PCR is more sensitive and highly specific than other identification methods. In the future, this approach will help in accurate diagnosis and will help in minimizing antibiotic resistance.

The coronavirus disease (COVID-19) is a respiratory disease caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). This study aimed to investigate the occurrence of COVID-19 in district Kech, associated risk factors, clinical presentation, and its effect on blood cells. A structured questionnaire was designed to collect the data and the samples were investigated by RT-PCR. In total, 575 suspects were screened, among which 64 (11.16%) had COVID-19 infection, 40.6% were males, and 59.4% were females. An increased positivity of 53.12% was measured in the younger age group (15-30 years) and the lowest (18.75%) was noticed in elders > 50 years. 95.3% of the patients were newly infected, and 7.7% had a contact history with COVID-19-infected patients. The clinical symptoms, such as fever, cough, nausea, vomiting, and diarrhea, were identified in 89.1%, 67.2%, 51.6%, 46.9%, and 12.5%, respectively. The prominent clinical features, like fever, cough, nausea, diarrhea, chest distress, chest pain, and psychological stress were observed. Noticeably, 10.9% of obesity and 7.8% of asthma patients were co-infected with COVID-19 disease including 39.1% of cases showed psychological trauma. Leucocytosis and a decrease in hemoglobin concentration and platelets were determined in COVID-19-infected patients. A significant effect was observed on the hematological profile, however, the effect was severe in the older age group (>50 years). The results suggest that the large population of the study area is infected by SARS-CoV-2, appealing to the need for surveillance on a large scale and the implementation of preventive measures to control further dissemination of the disease.

Az oktatásra vonatkozó források és a használt kézikönyvek áttekintése feltárja, hogy a tananyagot a Tiszántúli Református Egyházkerület konzisztóriuma írta elő, és döntései nem hagytak helyet az egyéni preferenciáknak. Sárospatakkal ellentétben Debrecenben a tananyagnak bele kellett férnie egy szemeszterbe. Az oktatás során sem nyomtatott, sem kéziratos természetjogi művek nem keletkeztek, csupán előadásjegyzetek maradtak fenn. A tanulmány megmutatja, hogy Debrecenben a nemesi szabadságjogok tudatának elmélyítésére esett a hangsúly a természetjog oktatása során.

AHLÂM MÜSTEĞÂNMÎ’NİN “SİYAH SANA YAKIŞIYOR” ROMANINDA SEMBOL FİGÜRLERİ VE GÜZELLİKLERİ
Authors: Alahmad Mohamad
Published: April 2024

Çağdaş Arap romanı, niteliğiyle günümüzün yaygın edebiyat türlerinden biridir. Sanat zenginliğini gerçekleştirebilmek için yenilikleri araştırma girişimlerinde çağın ruhuna ve değişikliklerine uyum sağlamaya çalışır. Bunu da alışılmışın dışında ifadeler kullanarak yapar. Bunların arasında geleneksel romana benzemesi mümkün olmayacak şekilde semboller kullanır. Bu farklılığını göstermek için geleneksel romanın kurallarını tümden değiştirir. Cezayir asıllı Ahlâm Müsteğânmî’nin “Siyah Sana Yakışıyor” adlı romanı sadece duygusal bir roman gibi gözükmektedir. Ancak derinlerine inildiğinde birçok sembolle karşılaşılır. Bu roman, yazarın yaşadığı toplumun çağdaş, siyasi ve sosyal problemlerini irdelediği gibi, çağımızda Arap ülkelerinde yaşanan önemli tarihi olayları da çağrıştırır. Bu makale, Ahlâm Müsteğânmî’nin “Siyah Sana Yakışıyor” adlı romanını kısaca tanıtmaya çalışır. Ardından da sembolün anlamı ve önemi üzerinde durur daha sonra da romandaki sembollerin eşsiz güzelliğine ışık tutar. Araştırmada birçok sonuca ulaşıldı; bunlardan en önemlisi, yazarın romanını oluştururken başta romanın başlığı, üç rakamı, ney, yer ve karakterlerin adları olmak üzere çeşitli sembollerden yararlanmasıdır. Yazar, yirminci yüzyılın son on yılında memleketi Cezayir'de yaşanan siyasi ve toplumsal olayları bu sembollerle ilginç bir üslupla dile getirmiştir.

Levantamento sobre os grupos de pesquisas em educação ambiental no triênio 2019 a 2022
Authors: Almeida Cinara Rodrigues de , Frenedozo Rita de Cássia
Published: April 2024

Pode-se dizer que educação ambiental deve ser abordada nos mais variados campos do conhecimento, criando condições formativas nos sujeitos. A Educação Ambiental Crítica, contrapõe as ideias hegemônicas, bem como relaciona conhecimentos sociais, econômicos, políticos e ambientais, permitindo constantes problematizações e interações entre o meio ambiente e a sociedade, pautando ações e práticas que auxiliem na construção ética, moral e reflexiva dos atores sociais. O presente estudo pretende buscar uma melhor compreensão da temática Educação Ambiental (EA). O artigo contempla inicialmente uma revisão bibliográfica sobre Educação Ambiental e a construção de uma abordagem crítica, política e reflexiva. A seguir trata especificamente do “estado do conhecimento” dos Grupos de Pesquisa sobre Educação Ambiental. Assim, foi realizada uma busca no banco de dados do Diretório dos Grupos de Pesquisas no Brasil do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), utilizando-se os termos “Educação Ambiental Crítica”. A seguir, verificou-se os Grupos de Pesquisas encontrados a partir dos termos “Educação Ambiental Crítica” no Triênio de 2019 a 2022. Nos 29 grupos encontrados, as áreas predominantes foram: dezessete grupos na área das Ciências Humanas, três grupos na área das Ciências Biológicas, dois grupos na área das Ciências sociais aplicadas, três grupos na área das Ciências Exatas e da Terra, um grupo na área de Letras, Linguísticas e Artes, três grupos com a denominação “outras” que referem-se às Ciências Ambientais. Este trabalho sugere aos pesquisadores a investigação das tendências das pesquisa de ensino sobre a Educação Ambiental e a análise crítica do que está sendo produzido e implementados nos ambientes escolares. Assim, haverá a contribuição para a compreensão do que foi produzido nessas pesquisas e como poderão implicar para que futuros pesquisadores em formação possam estabelecer questões de investigação que ainda não foram exploradas.

Published: April 2024

The bionic starfish-designed TES-TENG patch is applied directly to the patient's painful area. During movement, the deformed and fractioned patch generates a pulsed electrical output, which is then converted into an electric field and self-heated by the IDT to treat fasciitis. After TEF-TENG treatment, the total clinical effectiveness rate of the observation group was 94.54%, which was higher than that of the control group (75.83%), suggesting that TEF-TENG could enhance the clinical efficacy of the basic rehabilitation training. The self-powered TES-TENG, stimulates the nodules on the attachment points of the sacral spine or iliac crest muscles through external physical stimulation, repairs the tissue fibrosis that occurs after damage to the fascia, and enhances the proliferation and migration of fibroblasts in order to promote the dissipation of the nodules, while the TES-TENG synergistically utilizes the antiseptic, sensory properties, and heating properties to alleviate the pain.
SwiF-YOLO: A Deep Learning Method for Lung Nodule Detection
Authors: Ren Cheng , Hou Shouming , Hou Jianchao , Pang Yuteng
Published: April 2024

Lung cancer, a prevalent and lethal tumor globally, has a five-year survival rate of only 10%-16% for late-stage patients. However, early diagnosis and treatment can increase this rate to 52%. Lung nodules, as crucial indicators of early lung cancer, are challenging to detect due to their small size and similar features to other lung tissues. Therefore, developing an automatic detection method to improve the efficiency and accuracy of lung nodule detection is vital. This paper proposes a new method based on the YOLOx model, called SwiF-YOLO, to enhance the precision and efficiency of lung nodule detection. We introduced the Swin transformer to replace the main network of yolox-m, adopted the Adaptively Spatial Feature Fusion (ASFF) as the feature fusion method, and replaced the Intersection over Union (IOU) regression loss function with Generalized Intersection over Union (GIoU). These improvements aim to enhance the accuracy and efficiency of lung nodule detection, assisting doctors in diagnosing more accurately and quickly.
