Objectives

Choledochal malformation (CM) is a rare disease that can lead to malignancy and potential long-term sequelae despite surgical resection. There is no long-term follow-up data on patients after CM resection in Germany. We aimed to determine the long-term outcome of our patients with a duration of follow-up >10 years and focused on long-term sequelae and health-related quality of life (HRQOL).

Methods

All patients who had undergone CM-resection in our department from 01/1978 to 06/2009 were contacted. Patients were interviewed about postoperative complications and their present medical attendance. HRQOL was determined using Pediatric Quality of Life Inventory 4.0 (PedsQL), version for adults. The PedsQL scales the HRQOL from 0 to 100, with higher scores indicating a better HRQOL. Scores were compared to those published for a healthy population.

Results

Out of 56 patients who were contacted, 23 (41 %) participated. The median age at time of surgery was 3.1 years (6 days–16.1 years) and at time of the survey 24.3 years (11.1–53.8 years). Eighteen patients (78 %) had ceased their gastroenterologic follow-up at a median time of 4.3 years after surgery. Five (22 %) were still in gastroenterologic follow-up, two of these had an uneventful clinical course, and three (13 %) had ongoing complications attributed to the CM. One of these had undergone hemihepatectomy 34 years postoperatively due to bile duct stenosis, one had undergone removal of bile duct stones 14 years postoperatively, and one suffered from portal vein thrombosis with esophageal and jejunal varices. There was no mortality in our series. Median total HRQOL score was 89. There was no significant difference in the median total health, physical health, and psychosocial health scores of our patients in comparison to the healthy population.

Conclusions

We confirmed that the majority of patients after CM resection are lost to follow-up. Those who answered our questionnaire showed a good HRQOL. Given the high rate of severe long-term complications and the life-long risk of malignancy, we recommend a transition program for all patients.
Iconicity as the motivation for morphophonological metathesis and truncation in Nigerian Pidgin
Authors: Akinbo Samuel Kayode , Ekiugbo Philip Oghenesuowho
Published: June 2024

We present evidence for iconicity as the motivation for two patterns of morphophonological alternation in Nigerian Pidgin, also known as Naijá. To express an ‘unconventional positive’ in all varieties of Naijá, some nouns with the tone melodies H-L and L-H surface with the tone melodies L-H and H-L, respectively. In addition to unconventional positive, the Wafi variety of Naijá also expresses ‘unconventional negative.’ In this case, the first syllable of bisyllabic nouns (analogously, the first foot of four-syllable nouns) is transposed with the second syllable. However, in onsetful monosyllabic nouns, the initial consonant is deleted to express an unconventional negative. We account for the metatheses and truncation using transderivational faithfulness constraints and other independent constraints. Expressing the notion of unconventionality by changing the prosaic linear order of phonological elements in a word is a kind of form-meaning resemblance. Similarly, the association of (unconventional) negative with a reduction in a string of segments is another pattern of iconicity. This suggests that crossmodal depiction of sensory imagery, in addition to articulatory and auditory factors, can motivate morphophonological patterns. The morphophonological metatheses and truncation in Naijá contribute to the typology of morphophonological alternations with iconicity as their motivation. Most importantly, these patterns run counter to the claim that pidgins and creoles have simplified morphophonology.
The Regulatory Sandbox for the Pilot Project of Retail E-rupee Currency: Consideration for Reserve Bank of India
Authors: Nikam Rahul Jairam
Published: June 2024

Recent advancements in technology-based payment methods have prompted central banks all over the world to consider the possible advantages and hazards of issuing Central Bank Digital Currencies (CBDC) in order to keep up with the current innovation trend. The Indian payment system is no exception to this fintech innovation trend. As a result, the Reserve Bank of India (RBI) must begin considering related patterns and develop a phased implementation plan that progresses gradually through the pilot project. The present research is proposing a Pilot project on the issuance of retail e-rupee first. The research is primarily based on the normative method presenting a qualitative analysis of the creation of a digital rupee possibly like paper money and its smooth implementation. The study examines the potential effects of retail e-rupee implementation on the banking industry, monetary policy, technology architecture options, potential retail e-rupee applications, issuance methods, etc., as well as privacy issues. Thus, it will assist RBI in making policy decisions.
Advancing sustainable transitions: A spatial analysis of socio-environmental dynamics of landfills across the United States
Authors: Cannon Clare E. B.
Published: June 2024

Landfills are a kind of environmental hazard, linked to harms, such as the production of greenhouse gases and the accumulation of toxins in natural and human systems. Landfills contribute to climate change through emissions. Yet, the inclusion of socio-environmental dynamics of waste management systems in sustainability research has been understudied. Using a unique dataset of all landfills—construction and demolition, municipal, industrial, and hazardous—this study adds to sustainability research by focusing on waste management systems and to environmental justice research through inclusion of gender indicators and investigation of multiple forms of waste containment beyond solely hazardous facilities. Employing spatial error models, results suggest that communities of color, female-householder families, and disasters are associated with both nonhazardous and hazardous waste landfills. Understanding the relationships between social inequality and landfills improves our ability to plan for and develop more sustainable waste management systems, a key focus for advancing sustainability transitions.
Dismantling agroecology: The coming of the genetically modified cotton-agrochemical complex in an Indian highland frontier
Authors: Choudhury Chitrangada
Published: June 2024

This article traces the coming of a genetically modified (GM) cotton-agrochemical complex to highland eastern India. In this region of rich biodiversity and Indigenous systems of food and agroecology, GM cotton cultivation has seen a meteoric rise over the past decade. I explore how this shift from a no-input polyculture cultivation of community-held heirloom varieties to market-provisioned cotton seeds and agrochemicals marks a rupture that is fundamentally transforming the relationship of cultivators to land, seeds, and knowledge systems around agroecological practices. I contextualize this ongoing material and knowledge rupture in the specificities of location—both in an agroecological space and in a sociohistorical matrix of caste and region. Thus, what enables or erodes agroecological practices and ways of knowing is not simply the socioeconomic marginalization of smallholder cultivation, but more fundamentally a caste-prejudiced logic in India that, on the one hand, disrupts ecological ties of Indigenous communities to seeds, biodiversity, and land, and on the other denies the contributions of Indigenous knowledge, agriculture, and food cultures toward sustainability and biodiversity. This coming together of an industrial productivist logic with casteist prejudice is what I call casteist capitalism. Casteist capitalism structures both state programs of “tribal development” and agribusiness strategies in the region. Together they work to deride long-standing agroecological practices, and the Indigenous communities which practice them as “backward” and in need of reform toward a modern, commercial agriculture, as represented by chemical-intensive cotton monocropping.
The peruvian mining boom and dutch disease. Empirical evidence from 2003 to 2020
Authors: Sánchez Dávila Elmer
Published: June 2024

The aim of this paper is to verify whether Peru has suffered from Dutch disease. To do this, a VARX model with monthly data from 2003 to 2020 is used to analyze whether the mining boom prices of the 2000s and 2010s have had a negative impact on the real sector, especially on non-primary manufacturing. Results show that a real exchange rate shock explains 8.2% of the variation in non-primary manufacturing. Even though the effect is significant, it is relatively small, and this is due to the Peruvian Central Bank intervening to reduce exchange rate volatility
Growth and the real exchange rate: the role of technology
Authors: Márquez-Velázquez Alejandro
Published: June 2024

The aim of this paper is to assess the stability of the impacts of real exchange rate undervaluation and domestic technological capabilities on growth across development levels. Panel regressions with development-level interactions are used to test the stability of these variables’ impact on growth. The results show that real undervaluation is a driver of growth across all development levels, once technological capabilities are accounted for; however, it is more important for developing and developed countries than for emerging countries.
The Effect of Digital School Culture on Science Education and Scientific Literacy: A Scoping Review
Authors: Litina Sanita , Rubene Zanda
Published: June 2024

Thesis. In today's education scene, the incorporation of digital technology in schools has brought about a significant change beyond conventional limits, promoting a new cultural mindset known as the digital school culture. The development of “digital school culture” is one of the most prominent examples of the fusion of digital culture and school culture. The convergence of digital culture and scientific competence is becoming more evident, encompassing not only the comprehension of scientific knowledge but also the ability to adapt to swiftly evolving technologies, employ creative thinking, solve problems, make informed decisions, and apply scientific reasoning to real-world scenarios. This scoping review aims to understand the impact of digital school culture on students' scientific literacy and science educational outcomes.
Concept. Digital school culture is the integration of digital technologies and educational practices in schools, involving the attitudes, behaviour, and practices of educators, students, and administrators. The key elements of digital school culture include strategy and leadership, educator preparedness, school preparedness, technological responsiveness, and digital pedagogy.
Results and conclusion. This scoping review critically examines 10 studies published between 2009 and 2022, with a primary focus on components of digital school culture in science education. The review reveals that digital learning systems, digital environments to support student learning, digital technologies and tools, a digital curriculum, and pedagogical practices involving digital technology significantly improve scientific literacy.
Exploring the Absurdity of War: A Literary Analysis of Catch-22
Authors: Neziri Anita , Turku Marsela , Pavlíková Martina
Published: June 2024

Aim. This study aims to conduct a comprehensive analysis of the absurdities inherent in combat events as depicted in Joseph Heller's novel, Catch-22. The study seeks to explore how Heller utilizes literary techniques such as sarcasm, black humor, and surrealism to portray the contradictions, irrationality, and overall absurd nature of war. Additionally, the study aims to unfold the deeper societal implications, including dehumanization and moral degradation, presented in the novel.
Method. The research method employed in this study is primarily a qualitative literary analysis. The analysis involves a close examination of the text of Catch-22, focusing on the novel's characters, plot structure, narrative techniques, and the use of literary devices. It engages in critical interpretation and evaluation of how Heller employs sarcasm, black humor to convey the absurdities of war.
Results. The study reveals that Joseph Heller employs a unique set of literary techniques, including non-sequential narrative, broken chronology, and cyclical motifs, to vividly capture the chaotic and absurd nature of combat events.
The analysis uncovers recurring themes such as bureaucratic absurdities, loss of personal agency, dehumanization, and the existential toll of war. The study highlights the significance of the Catch-22 paradox as a central motif, illustrating the circular and illogical nature of bureaucratic processes during war.
Conclusion. Joseph Heller's Catch-22 serves as a powerful critique of the absurdities prevalent in wartime. The Catch-22 paradox emerges as a symbolic representation of bureaucratic folly, encapsulating the struggle of individuals caught in the machinery of conflict.

Successful Treatment of Nasopalatine Duct Cyst After Maxillary Anterior Implant Surgery: A Case Report
Authors: Gao Xuyang , Dai Shiai , Yan Xia , Jia Xueting , Huang Baoxin , Zhang Haidong , Wei Diyuan , Guan Xiaoyuan , Shi Dong , Meng Huanxin
Published: June 2024

Sporadic studies have reported the occurrence of nasopalatine duct cysts after maxillary anterior implant surgery, and the treatment methods still have clinical uncertainty. We report a potential therapy method that successfully treated a nasopalatine duct cyst that developed and expanded 1 year after maxillary anterior implant placement following periodontally hopeless teeth extraction. The nasopalatine cyst was treated surgically without removing implants. During flap surgery, the cyst was removed intact, and the exposed implant’s surface was debrided thoroughly by hydrogen peroxide (H2O2) rinsing, glycine air polishing, and saline rinsing. To deal with the significant bone defect caused by the cyst, a bovine porous bone mineral injected platelet-rich fibrin (BPBM-i-PRF) complex was applied to fill the defect, following a resorbable collagen membrane to cover. Seven years after surgery, no cyst recurrence was observed, and bone regeneration in the bone graft area was stable. The implants functioned well without mobility. For nasopalatine duct cysts associated with dental implant placement, complete surgical debridement and longitudinal stable bone regeneration are possibly accessible by regenerative surgery without implant removal.
NUMERICAL INVESTIGATION ON THE INFLOW MACH NUMBER VARIATIONS IN A STRUT INJECTED CAVITY-BASED SCRAMJET COMBUSTORS
Authors: Rajesh A. C. , Jeyakumar S. , Jayaraman K. , Karaca Mehmet
Published: June 2024

The effect of enhancing the air inflow Mach number of a strut-injected cavity incorporated into a scramjet combustor is numerically studied. The computational investigations are performed using the commercial code Ansys Fluent software. The simulation is carried out using the SST k-ω turbulence model with single-step reaction chemistry and a two-dimensional planar model using the Reynolds-averaged Navier-Stokes (RANS) method. The cavities are positioned downstream of the strut injector that are fixed to the top and bottom walls. This configuration enables the analysis of the shock wave pattern and its correlations with shear layer mixing features. Three inflow Mach numbers are opted for the present investigation, i.e., Mach 2.0, 2.5, and 3.0. The investigations are accomplished on the flow pattern, static pressure, and temperature distributions. Performance analyses for the twin cavity designs that fit into the German Aerospace Center (DLR) scramjet are performed throughout the entire combustor length. A reduction in combustion chamber length by 20% and complete combustion is achieved from the twin cavity configuration as compared to the baseline model. The overall pressure drop is increased around 23% due to the formation of additional shock waves from the cavities. Moreover, the combustion zone prolongs along the flow direction due to the increase in the inflow Mach numbers.

Authors: Pekcan Diğdem , Arslanoğlu Mehmet
Published: June 2024

Bu çalışmada, Türkiye’ye gelen doğrudan yabancı yatırımlar Yeni Kurumsal İktisat perspektifinde analiz edilmektedir. Türkiye’ye gelen doğrudan yabancı yatırımların potansiyelinin altında kalma nedenlerinin; kurumlar, işlem maliyetleri, mülkiyet hakları gibi argümanlara dayandırılarak incelenmesi hedeflenmektedir. Bu nedenle kurumsal belirleyicilerin Türkiye’ye gelen doğrudan yabancı yatırımlar üzerindeki etkisi araştırılmıştır. 1999-2021 yıllarını kapsayan bu çalışmada; dışa açıklık, enflasyon, insani gelişme endeksi değişkenleriyle birlikte yönetişim göstergeleri, sivil özgürlükler ve siyasi haklar da kurumsal değişkenler olarak yer almaktadır. Kurumsal değişkenlere Asal Bileşenler Analizi uygulanarak formel kurumlar değişkeni elde edilmiştir. Çalışmada, üç farklı model oluşturularak ARDL sınır testi yöntemiyle formel kurumlar ile Türkiye’ye gelen doğrudan yabancı yatırımlar üzerindeki ilişki incelenmiştir. Buna göre dışa açıklık değişkenin doğrudan yabancı yatırımlar üzerinde pozitif bir etkiye sahip olduğu ve formel kurumlarla arasında uzun dönem ilişkisi olduğu tespit edilmiştir. Enflasyon değişkenin doğrudan yabancı yatırımlar üzerinde negatif bir etkiye sahip olduğu ve formel kurumlarla arasında uzun dönem ilişkisi olduğu tespit edilmiştir. Uzun dönem katsayıları incelendiğinde ise her iki değişkene kıyasla formel kurumların doğrudan yabancı yatırımlar üzerinde daha fazla etkiye sahip olduğu gözlenmektedir. İnsani gelişme endeksinin doğrudan yabancı yatırımlar üzerinde pozitif bir etkiye sahip olduğu ve formel kurumlar ile uzun dönem ilişkisi olduğu tespit edilmiştir. Ancak insani gelişme endeksinin doğrudan yabancı yatırımlar üzerinde daha etkili olduğu sonucuna ulaşılmaktadır.

Şâfiî’nin Zinanın Hürmet-i Musâhereyi Gerektirmediği Konusundaki Görüşünün Temellendirilmesi
Authors: Demirboğa Selman
Published: June 2024

Fakihler evlenme engellerini sürekli ve geçici olmak üzere iki kısım altında ele almışlardır. Sürekli evlenme engelleri de kan bağı, süt ve sıhriyet yoluyla oluşan haramlık olmak üzere üç kısma ayrılmaktadır. Kan bağı ve süt yoluyla oluşan haramlık konusunda fakihler arasında bir tartışma bulunmamakla birlikte sıhrî hısımlıkla ilgili ihtilaf bulunmaktadır. Evlenmenin taraflar arasında doğurduğu bu hısımlık, klasik fıkıh literatüründe sıhriyet mahremiyeti (hürmet-i musâhere) olarak ifade edilmiştir. Bu bağlamda zinanın hürmet-i musâhereyi gerektirip gerektirmediği problemiyle ilgili olarak doktrinde iki görüş ortaya çıkmıştır. Hanefîler, Hanbelîler ve Şiî fakihlerin ekseriyetinin savunduğu birinci görüşe göre zina, hürmet-i musâhereyi gerektirir. Buna karşılık Şâfiîler, Mâlikîler, Zâhirîler ve Hanbelîler’den İbn Kayyim el-Cevziyye’nin savunduğu ikinci görüşe göre ise zina ile hürmet-i musâhere sabit olmaz. Bu çalışmanın temel amacı, zinanın hürmet-i musâhereyi gerektirmediği görüşünde olan Şâfiî’nin görüşünü temellendirmektir. Zira tespit edebildiğimiz kadarıyla Şâfiî’nin bu meseleyle ilgili görüşünün temellendirilmesi konusunda spesifik bir çalışma bulunmamaktadır. Çalışmada öncelikle fakihlerin zinanın hürmet-i musâhereyi gerektirip gerektirmediği konusundaki görüş ve gerekçeleri ele alınmıştır. Daha sonra Şâfiî ve Şâfiî fakihlerin konuyla ilgili görüş ve gerekçeleri zikredilmiş ve bu yönüyle Şâfiî’nin savunduğu hukuk mantığı ortaya çıkarılmaya çalışılmıştır. Konuyla ilgili görüş ve gerekçeler her ekolün temel fıkıh eserleri esas alınarak incelenmiştir.

Published: June 2024

Water supply is the great challenge for climate change and overpopulation. A nanofiber mat consisting of polyvinyl alcohol (PVA), nanoTiO2, and citric acid (PTC) was prepared using an electrospinning technique at a constant flow rate (0.5 ml/h). The morphology of the mat was detected using (FESEM) technique and image J software. The results show that the mat has a nanofiber morphology with an average diameter of 170 nm. This mat was used to remove methylene blue (MB) from water in two ways, the adsorption process and by photodegradation using UV light. The kinetic study of the adsorption of methylene blue MB on a PTC mat was carried out. Results show that the pseudo-second order is the best to describe the adsorption, of MB, and the intraparticle diffusion is the rate determining step. Seven isotherm models; four of two-parameters and three of three-parameters were used to examine the adsorption experimental data by applying linear and non-linear regression methods using six error functions. The results showed comparable data between linear and non-linear regression methods for two parameters isotherms, and the best isotherm fitting with the data were Freundlich and Temkin models. On the contrary, three parameters isotherms showed distracted data between linear and non-linear regression methods. In addition, the results appear that the best predictive error function was Chi-square.

MFL detection of adjacent pipeline defects: a finite element simulation of signal characteristics
Authors: He Mo , Zhou Zhiyong , Qin Lin , Yong Hao , Chen Chao
Published: June 2024

Magnetic flux leakage (MFL) is one of the most commonly used non-destructive testing technologies for defect detection of oil and gas pipelines. Analysing the MFL signals of different defects and thus identifying the types and sizes of pipeline defects are the key and difficult points,
obtaining wide attention in both academic and engineering domains. Most of the past research has focused on the MFL signals of single defects, neglecting the interference caused by adjacent defects, possibly leading to errors. As a result, this study develops a finite element method (FEM)
model based on Maxwell theory for the MFL signal of adjacent defects and analyses the signal characteristics, considering both inner and outer defects. The interference distances caused by inner and outer defects are analysed and the shape and size of the defects are also considered to identify
defects in multiple adjacent defects. The model results show that the interference caused by adjacent defects manifests the superposition of the leakage magnetic field in axial and radial components. The interference weakens with increasing distance between adjacent defects. To quantify the
interference caused by different defects, a concept of 'interference distance' is developed using the change rate of the peak value of MFL signals. The influence of different factors on the interference distance is explored by analysing the MFL signal under different factors. Therefore,
this study can support the identification of adjacent defects on steel pipelines using MFL technology, reducing the errors caused by adjacent defects.

Objectives: Albumin is commonly used for various indications; however, there is conflicting data regarding its appropriate use in different clinical cases. This study aimed to determine the pattern and appropriateness of albumin use among cancer patients at the King Hussein Cancer Center in Jordan. Methods: A retrospective analysis was conducted on adult cancer patients who were prescribed albumin between January 2019 and July 2020 in both outpatient and inpatient settings. Data collected included demographics, prescribing services, indications and dosing regimens. A literature review was performed using PubMed to assess the appropriateness of albumin indications and dosing regimens against current guidelines, drug information resources and the package insert. Results: Albumin was prescribed to 1,361 patients during the study period. Each patient received an average of 74.4 ± 89 g of albumin for an average of 2.6 ± 1.8 days. Albumin use was deemed appropriate in 69% of the patients. The critical care service accounted for the highest albumin consumption, with 37% of prescriptions for septic shock. Inappropriate use of albumin was most prevalent in the medical solid tumour services (40.8% of prescriptions), primarily for edema (28%). Conclusion: To the best of the author’s knowledge, this study is the first to evaluate albumin use in a large cohort of oncology patients. Approximately one-third of the albumin prescriptions were considered inappropriate. Continuous education on appropriate usage and regular evaluations of guideline adherence are essential to ensure proper utilisation of albumin in cancer care.

Objective: The objectives of this study were to develop two biodegradable periodontal chips containing Salvadora persica or Benzyl isothiocyanate (BITC) extract and evaluate its clinical effectiveness in managing periodontitis. Methods: Chips were formulated from Salvadora persica, Benzyl isothiocyanate (BITC) and chitosan; twelve patients with periodontal pockets measuring ≥5 mm participated in this study. Overall, 240 periodontal pockets were evaluated. All patients were treated with full mouth scaling and root planning (SRP) at baseline. Periodontal pockets were divided into four groups. One of which is the control group, while group two received plain chitosan chip. Group three received chips containing Salvadora persica extract, and group four received chips containing BITC. Plaque index (PI), bleeding on probing (BOP), periodontal probing pocket (PPD) depth, and clinical attachment levels (CAL) using acrylic stents were recorded at days 0 and 60 only. Results: Data were statistically analysed; Chi-square t-test and an ANOVA were used. Results showed significant improvement in plaque index, bleeding on probing, and reduction in periodontal pocket depth in all four groups (p<0.05). The gain in clinical attachment level was significantly higher (p<0.005) among the group receiving Salvadora persica chips compared to the control and other chip-treated groups. Conclusion: Periodontal chips containing S. persica can be used as adjuncts to treat patients with periodontitis.

Published: June 2024

Objectives: Scrub typhus is the most common rickettsial disease in India, caused by Orientia tsutsugamushi and transmitted by chigger mites. Previously prevalent in South India, a resurgence of scrub typhus cases has recently affected Eastern India. This study aimed to estimate the prevalence and describe the clinico-laboratory profile of scrub typhus in paediatric patients (1–12 years old) living in Eastern India. Methods: This prospective observational study was conducted from January to December 2019 at the Dr B C Roy Post Graduate Institute of Paediatric Sciences, Kolkata, India. All acute undifferentiated cases of febrile illness, in patients aged between 1–12 years, were tested using scrub typhus serology by ELISA. Demographic details, clinical features, laboratory findings, complications and treatment outcomes of these scrub typhus patients were extracted and analysed. Results: Out of 1,473 patients with acute febrile illness, 67 (4.5%) children were diagnosed with scrub typhus. The mean age of the selected patients was 5.22 ± 3.05 years, and the majority (64.2%) had been running a fever since the preceding 7–14 days. Gastrointestinal symptoms such as vomiting (43.3%) and abdominal pain (32.8%) were most frequently observed. Major clinical signs of scrub typhus were hepatomegaly (41.8%) and splenomegaly (31.3%). Complications were observed in 74.6% of patients, with thrombocytopenia (40.3%) and meningoencephalitis (29.9%) occurring more frequently. The case fatality rate of the study sample was 1.5%. Conclusion: Classical eschar was absent in three-fourth of the studied patients. Hence, this study advocates laboratory scrub typhus tests for all suspected cases in the endemic region (Eastern India). Prompt treatment with doxycycline and/or azithromycin could prevent complications such as thrombocytopenia/meningoencephalitis and reduce mortality.

Physics Model-Based Design for Predictive Maintenance in Autonomous Vehicles Using AI
Authors: Aravind Ravi , Vinalbhai Shah Chirag
Published: June 2024

In this paper, a model of predictive auto-maintenance is developed. This model is then used for auto-maintenance in the electrical and electronic systems of an autonomous vehicle. Along with traditional sensors, an advanced X-ray vision system is used to detect faults in the system. It uses massively scaled integration (MSI) or very large-scale integration (VLSI) integrated circuitry and other designs to enable the creation of systems containing many components. Commercial applications are being researched and developed, especially in robotics.
In this paper, reconfigurable devices are employed to create fault-tolerant digital systems for the predictive auto-maintenance subsystem of the autonomous vehicle and achieve the highest level of auto-maintenance.
The development of an intelligent, predictive auto-maintenance model is a challenging task that requires the use of modern technologies, ideas, and concepts. Despite recent progress in predictive maintenance, this work takes inspiration and begins with physics models. It seeks to examine the type of deterioration seen in electronic components and connections. Relationships between local failures and global system malfunctions are examined. The aim is to eliminate recurrent system malfunctions through the application of focused auto-maintenance.
The development involves the design and modeling of AI system behavior and takes into account the principles underlying human reasoning on the behavior of technical systems. UML diagrams that visualize human reasoning during occasional self-reflective discussions of the forward reasoning process are presented

This study was carried out to describe the mechanical behavior of different materials in terms of shear strength, cohesion and friction. For this purpose, an experimental shear tests were carried out. The soils used for the preparation of the samples were the Chlef sand, Chlef silt and M’zilla clay and a mixture composed of 50% of silt and 50% of clay. The soils were prepared by mixing Chlef sand with fines content of silt, clay or clay silt ranging from 0, 10, 20, 30 and 40%. The tests were conducted on sand samples prepared at a relative density of 20% representing a loose state and subjected to three normal stresses of 100, 200 and 400 kPa. All the tests were conducted at constant displacement rate of 1.00 mm/min. From the obtained results, it can be seen that the clean sand showed the highest shear strength at a small strains. At large strains, sands with 30% clay rather than 30% clay silt showed the highest shear strengths respectively. More contracted sands have the greatest increased maximum shear strengths. The sand with clayey silt, at a fine content of 20%, develops the most increased cohesion, among the other silty-clayey sands, together with the most reduced shear strength in elastic behavior. The sand with 40% of silt content develops a greater internal friction angle, however, the other silty sands, showed reduced shear strength, at the same behavior. To validate these findings, numerical simulations were performed on sand-silt mixtures using the hypoplastic model. The results indicated that the hypoplastic model accurately predicts the shear behavior of sand-silt mixtures in direct shear test, providing realistic insights into the effects of fines on the mechanical properties of the soil.

Authors: Brygała Magdalena , Korol Tomasz
Published: June 2024

It has become crucial to have an early prediction model that provides accurate assurance for users about the financial situation of consumers. Recent studies focused on predicting corporate bankruptcies and credit defaults, not personal bankruptcies. Due to that, this study fills the literature gap by comparing different machine learning algorithms to predict personal bankruptcy. The main objective of the study is to examine the usefulness of machine learning models such as random forest, XGBoost, LightGBM, AdaBoost, CatBoost, and support vector machines in forecasting personal bankruptcy. The research relies on two samples of households (learning and testing) from the Survey of Consumer Finances, which was conducted in the United States. Among the estimated models, CatBoost and XGBoost showed the highest effectiveness. Among the most important variables used in the models are income, refusal to grant credit, delays in the repayment of liabilities, the revolving debt ratio, and the housing debt ratio.

Introduction: Anemia experienced by pregnant women will hurt the baby, namely the risk of premature birth, low birth weight, and an increased risk of perinatal death. This study aims to determine the relationship between family support and the behavior of pregnant women in efforts to prevent anemia. Methods: This study used analytical research with a cross-sectional approach, the population in this study was all pregnant women in Madiun. This study used purposive sampling techniques. The sample used in this study was 112 respondents. To find out the relationship between variables in this study, the Chi-Square statistical test was used with the result that if the p-value is 0.05, it means that there is a significant relationship between the two variables. Results: The results of the study using the Chi-Square correlation test showed that the Fischer Exact Test value was 0.001. Because the Chi-Square test value is 0.001 < 0.005, it can be concluded that there is a relationship between family support and the behavior of pregnant women in efforts to prevent anemia. Conclusions: Families are expected to always provide motivation, help, and accompany pregnant women so that pregnant women feel safe, comfortable, and calm.
