Predicting the residual resource of railway tracks
Authors:   Institute of Mathematical Machines and Systems Problems of the National Academy of Sciences of Ukraine, Cespedes Garsia N.V.
Published: September 2024

The article is devoted to defining modern methods for assessing the residual resource of railway tracks. Since steel rails are one of the main components of railway transportation, predicting the service life and determining the residual resource of rails are important for ensuring the safe operation of railways. The main sectoral international and domestic regulatory documents have been analyzed, and the general state of the problem has been investigated. It has been estab-lished that the service life of railway tracks is determined mainly by the degree of dynamic loading, the number of initial defects during manufacture, the quality of steel rails, and the in-fluence of climatic and electromagnetic loads. Some methods and approaches to determining the residual resource in the world practice, which are based on experimental laboratory tests for the durability of decommissioned defective rails, have been studied. On the basis of the discov-ered mechanisms for the formation and development of defects, some specific recommenda-tions have been developed in order to increase the operational resource of railway tracks. How-ever, these methods do not take into account the stochastic aspects of the physics of degradation and destruction processes. Therefore, the most effective method for determining the residual resource of various objects is the probabilistic-physical method, which is based on the analysis of the dynamics of the change of the determining parameter. In accordance with the methodolo-gy of DSTU 8646:2016, given the data on the initial, current, and limited missed tonnage in which there are no rail failures, the calculation of the residual resource of railway rails is given. Calculations of the residual resource using the probabilistic-physical method on the example of heat-treated rails of passenger railways and using the relative values of the resource parameter have shown results that correspond to statistical data from the operation. The use of the method based on DM-distribution of failures helps to extend the life of rails and reduce operating costs by optimizing maintenance and repair processes.

Authors: Bhatti Huma , Ying Yi-Lun , Long Yi-Tao
Published: September 2024

Ion selectivity is a fundamental feature for designing advanced nanopores/channel systems, for example, biosensors or selectively permeable membranes. Comparison between different studies is a way to find and design the nanopore/membrane with pronounced selectivity. However, there is a huge hurdle in comparing the ion selectivities between studies, resulting from different equations from diverse scopes of science. Here, the authors from
“
Addressing challenges in ion-selectivity characterization in nanopores
”
emphasized the misinterpretation of the traditionally used Nernst and Goldman–Hodgkin–Katz equations in the previous literature and suggested the use of uniform criteria to overcome this ambiguity. We highlight the potential future applications of using uniform criteria in describing ion selectivity, which is beneficial to developing a massive AI-based databank. This databank would be advantageous for predicting and designing the ion selectivity of nanopores/nanomaterials in question for various applications in biological and material sciences.

Published: September 2024

Background: Computed tomography (CT) scan plays an important role in the diagnosis of the COVID-19. Lung involvement appears in different forms on CT images. Absorbed dose to the patients may exceed diagnostic reference levels. This study aimed to investigate clinical symptoms, findings of lung CT scan, and absorbed dose to the patients. Methods: This cross-sectional descriptive study was conducted in two CT scan centers in Hamadan: Besat and Sina. CT images of 163 patients with positive real-time polymerase chain reaction (PCR) tests were interpreted by six experienced radiologists. Volume CT dose index (CTDIvol), dose length product (DLP), and effective dose were calculated in both centers and compared using the Mann-Whitney statistical test. Results: The most common findings in the CT images were ground-glass opacification (GGO), consolidation, and the combination of GGO and consolidation. CTDIvol, DLP, and effective dose to the patients were respectively 1.64±5.24 mGy, 177.12±59.03 mGy.cm, and 3.01±1.00 mSv in Sina hospital and 4.58±1.91 mGy, and 2.60±1.02 mSv in Besat hospital. The difference between quantities in the two centers was statistically significant (P>0.05). Conclusion: The most common findings in lung CT images of patients with positive polymerase chain reaction (PCR) tests were GGO and consolidation. Furthermore, there were differences in radiation dose to patients between hospitals, indicating the need for optimization.

Published: September 2024

Background: Nausea and vomiting after a cesarean section (CS) are among the common side effects that cause dissatisfaction among doctors. The aim of this study was to compare the effects of intravenous midazolam and ondansetron on the reduction of nausea and vomiting after spinal anesthesia in CS. Methods: This double-blind clinical trial study was conducted on CS candidates who underwent spinal anesthesia (N=80). After spinal anesthesia, the patients were randomly divided into two groups. Midazolam was administered to one group and ondansetron to the other group. The severity of nausea, the severity of vomiting, and the degree of satisfaction were recorded during surgery and recovery. Results: No significant difference was observed between the two groups in terms of the severity of nausea and vomiting. In addition, the results demonstrated that the level of satisfaction in the midazolam group was higher than that in the ondansetron group, but this difference was not statistically significant (P<0.05). Conclusion: The results of this study showed that midazolam can reduce nausea and vomiting. On the other hand, the results confirmed that both ondansetron and midazolam can have the same effects on reducing nausea and vomiting.

Published: September 2024

Introduction: Although age-related changes have caused more and different information needs in the older adults, their participation in online search is low. This study aimed to explore the process of online health information-seeking (OHIS) in the older adults. Methods: The current qualitative study was conducted through applying a grounded theory approach using Corbin and Strauss method in Tabriz from 2018 to 2019. Adopting a purposive and theoretical sampling method 19 older persons, 2 members of their family, a doctor, a psychologist, 4 gerontologists, and a health education specialist participated in this study. In-depth individual interviews were used as the main method of data collection. Results: This study indicated that the core phenomenon in the OHIS process was "struggling for healthy survival". Therefore, older people tried to identify and choose strategies to relying on yourself in taking care of their health. Avoidance of dependence as a contextual factor influenced their choice. Finally, this complex process led to OHIS. Conclusion: This study provides important insights for healthcare professionals and introduces some strategic implications for improving older people’s access to appropriate health information. The OHIS theory presented in this study is a potentially valuable tool for policymakers to take measures to support older people in their self-care.

Introduction: Although the life expectancy of kidney patients has increased due to hemodialysis (HD), the disease affects their lives in various ways. In this study, we systematically reviewed the relationships between health literacy (HL) and bio-behavioral and psycho-social outcomes in HD patients, to determine the necessary information needed for both micro- and macro-level health decision-making. Methods: We performed a comprehensive search for globally eligible studies (from 2000 to 2020) on PubMed, EMBASE, ProQuest, CINAHL Nursing, Cochrane Library and Google scholar. The quality assessment of the studies was performed using the standardized tool of the Joanna Briggs Institute (JBI). Results: Among 29 included studies, 23 and 6 articles were of medium and low quality, respectively, and no article was of high quality. In general, 7210 participants were included in these studies. In total, the lowest, highest and the average level of HL in all researches were reported to be 16%, 76.9% and 31.25% respectively. The findings showed a moderate level of evidence for the relationship of HL with self-care-associated outcomes, disease-related biomarkers, QOL, and perceived social support. Conclusion: Despite study heterogeneity and low quality, HL was found to be positively contributed to self-care behaviors, perceived social support and QOL of HD patients. HL seems to play an underpinning role in promoting HD patients’ QOL and its bio-behavioral and psychosocial determinants.

Published: September 2024

Introduction: Sudden unexpected infant death (SUID) and sudden infant death syndrome (SIDS) collectively represent one of the leading causes of infant mortality worldwide. There are a range of evidence-based modifiable risk factors for both, particularly related to the infant’s sleep environment. Oftentimes, social determinants of health impact optimization of an infant’s sleep environment, thereby compromising their safety and elevating their risk for SIDS and SUID. Many kinds of community interventions that include campaigns and programs have sought to address these environmental modifiable risk factors that contribute towards heightened risk for SIDS and SUID. However given resource limitations, reach and access considerations, and scarcity of a streamlined harmonized process to draw on the strengths of a community in SUID and SIDS reduction, there is mixed success with these interventions. Methods: Although community baby showers are rising as a trending health promotion intervention to optimize access to care, resources and support to infants and their caregivers as well as optimize infant growth and development, there is no review paper to date that consolidates the strengths and limitations in the quality, delivery and evaluation of community baby showers as a continued focus for future public health interventions surrounding the infant population which informs the development of this scoping review. Results: Specifically, this review synthesizes the commonalities, differences, key findings, intervention components as well as gaps in research and practice on community baby showers across published studies (n=20) and secondary sources (n=4). Conclusion: Clinical and public health implications are also closely examined and further inform recommendations for future directions that draw on the strengths and build off the limitations of findings from this review to heighten the clinical and public health impact and further assess the efficacy of community baby showers as an evidence-based community engagement and health promotion intervention for our next generation of infants and their families.

Published: September 2024

Introduction: Radiologists and radiotherapists are frequently exposed to elevated levels of radiation compared to the general population. This study aimed to assess the impact of Health, Safety, and Environment (HSE) conditions on employees in radiology and diagnostic imaging services regarding the incidence of cancer. Methods: This cross-sectional survey comprised two components: (1) Evaluation of HSE conditions in radiology and diagnostic imaging services within hospitals, and (2) Examination of radiation doses received by radiologic technologists, along with investigating cancer incidence among these workers. Results: Among the 29 and 54 participants, the two-month and annual doses exceeded standard levels. The HSE condition survey revealed mean scores across all hospitals of 75.5±10.2 for radiation safety, 88.2±8.5 for general safety, and 47±10.6 for emergency safety. No cases of suspected radiation-related cancer symptoms were identified. Higher scores on metrics such as individual dosimeter usage, adherence to proper Personal Protective Equipment (PPE), equipment safety checks, device leak testing, presence of safety warnings, and attention to HSE issues were associated with reduced radiation exposure and fewer doses received by participants. Conclusion: Adherence to safety protocols leads to decreased radiation exposure and mitigates concerns regarding occupational diseases.

Published: September 2024

Background. The health of retirees, as an expanding and vulnerable group, is of particular importance in society, and it is necessary to prioritize their problems in critical situations such as the spread of the coronavirus. The current study aimed to investigate the impact of social and cultural capital on the level of fear of COVID-19 among retired employees of Tabriz University of Medical Sciences (TUOMS). Methods. This survey-based research employed a descriptive-explanatory design and was practical in terms of purpose. This study selected 410 retirees from TUOMS in Iran using a simple random sampling method. The data collection tools in this study included three questionnaires: cultural capital, social capital, and fear of COVID-19. We tested the research hypotheses using SPSS software (version 22). Results. The bivariate results of the study indicated that social capital and its dimensions (social networks, social trust, and social participation) and cultural capital and its dimensions (embodied, objective, and institutional) had a significant and inversed effect on the level of fear of COVID-19 among the retirees. The regression model of fear of COVID-19 also found that both independent variables (social capital and cultural capital) were statistically significant and could explain about 36% and 31% of the changes in the dependent variable (fear of COVID-19 among retirees), respectively. Conclusion. This study indicated a significant and inverse relationship between social and cultural capital and the level of fear of COVID-19 among the retirees of TUOMS. The findings of the present study can be generalized to all retired TUOMS employees. Therefore, healthcare policymakers should take effective measures to increase the funds allocated to diseases such as COVID-19 and reduce the fear of the disease, which is a risk factor for physical and mental diseases.

1950-1960 YILLARI ARASINDA DEMOKRAT PARTİ’NİN TARIM POLİTİKASI ÜZERİNE BİR DEĞERLENDİRME
Authors: Akbal İsmail , Yörük Bahadır
Published: September 2024

Türkiye gibi üretim ekonomisinin tarım ağırlıklı olduğu ülkelerde siyasal iktidarı elinde bulunduranların en fazla üzerinde durduğu konu şüphesiz tarım olmuştur. Bu ülkelerde tarımın karşılaştığı birçok ağır sorunlar vardır. Bu ağır sorunları tekil üreticilerin çözmek için aldığı tedbirler yetersiz kalmakta ve devlet bu alanlara müdahale etmek zorunda kalmaktadır. Devletin belirli bir amaçla sorunların çözümü için aldığı tedbirlerin tümü “Tarım Politikası”nı oluşturmaktadır.
Her ülkede devletin uyguladığı tarım politikası, ülkelerin kendine özgü sorunlarının çözümüne yöneliktir. Özellikle Türkiye gibi gelişmekte olan ülkelerde tarım politikası hep üretimin gelişmesine yönelik olmuştur. Ürün fiyatı için yürütülen politikada stok politikası ve gereken finansman kaynaklarının kamuca yüklenilmesiyle tamamlanmaktadır; Merkez Bankası ve Ziraat Bankası kredileri bu nitelikte değerlendirilmektedir.
Çok partili hayata geçişle birlikte Demokrat Parti'nin kurulması ve kısa sürede toplumun büyük kesiminin, özellikle tarım kesimindeki kitlelerin, desteğini alarak iktidara gelmesiyle birlikte tarım politikası aslında değişmemiş, devletçilik ilkesi devam etmiştir. Değişen tek şey tarım kesimine verilen desteğin artarak devam etmesidir. Fakat burada dikkat edilmesi gereken desteğin küçük çiftçiye değil de toprak ağalarına gitmesidir. Büyük toprak sahibi ve tüccarların tarımda makinalı üretime geçişin sağladığı yararlardan en büyük payı alma çabaları, bunu engelleyecek bir siyasal tavrın olmaması nedeniyle büyük ölçüde başarıya ulaşmıştır. Siyasal açıdan güçlü bir konuma sahip olmalarının yarattığı imkânları kullanan büyük toprak sahipleri, hükümetin ekim alanlarını genişletmek amacıyla başlattığı meraların tahrip edilmesi, hazine topraklarının özel girişimcilerin kullanımına açılması ve bataklıkların kurutulması gibi girişimleri sonucunda yaratılan yeni tarımsal alanların büyük bir kısmını kendi mülkiyetlerine geçirmişlerdir. Bu durum küçük üreticilerin mülksüzleşmesine neden olmuş; sonuçta Türkiye’de ciddi bir içgöç olayı yaşanmıştır. 1950-1960 arasında dört büyük şehirde nüfus % 75 artmıştır. Demokrat Parti, sınıfsal temelini oluşturan büyük toprak sahiplerinin ve ticaret burjuvazisinin çıkarlarını zedelemeden büyük kısmı küçük üreticilerden oluşan kendi oy tabanını iktisadi açıdan hoşnut tutabilmiştir.
Bu çalışma Demokrat Parti’nin uyguladığı tarım politikasının genel özelliklerini, başarılı ve başarısız yönlerini, uygulanan tarım politikasının siyasi ve sosyal sonuçlarını ortaya koymak için hazırlanmıştır. Çalışma literatür tarama yöntemi ile hazırlanmıştır. Daha çok ikincil kaynaklar ve istatiksel veriler üzerinden hazırlanmıştır.

Published: September 2024

In this paper, we use a hybrid approach known as the extended balanced singular perturbation technique to compute the H_∞-norm of a transfer matrix of a dynamical system. The transfer matrix's order is first reduced using the balanced truncation approach, and its H_∞-norm is then found using the singular perturbation method. Both the singular perturbation technique and the balanced truncation approach methods are provided with computer algebraic instructions. The method is then applied to a decentralized interconnected system, and the error analysis of the solution is investigated.

Norio-72 well was drilled by CanArgo Georgia ltd in 2002-2006, within of North board of the eastern end of the Adjara-Trialeti folded zone. Purpose of drilling was specification of geological structure of the territory, penetration and potential evaluation of known, oil-bearing vulcanic-sedimentary formation of region near Tbilisi. Drilling was conducted in a very difficult geological conditions and ended with heavy collapse at 4900m. It is still a matter of discussion whether the well had penetrated Middle Eocene productive layers. Solving this problem has a significant meaning for specification the depth structure of the above mentioned territory and for oil-gas exploration issues. According to the complex analysis of geological (biostratigraphic, lithological-mineralogical), gephisical (exploration and production) and drilling data and on the basis of our study of basically to the microscopic research of about 1000 samples (drilled parts of rock) we can conclude that the well had not penetrated the vulcanogens of Middle Eocene. It penetrated Upper (Middle and Lower Sarmat), Middle (Konkian, Karagan, Chokrak, Tarkhan), Lower Miocene (Kotsakhuri, Sakharaulo) and Oligocene (4230-4900m interval) thick sandy shale formation in a consistent manner. Last 90m of the geological section of the well is formed by Maykop formations not the tuffs, mainly non-carbonaceous, almost mute shale rocks partially, sandstones and siltstones, as it turns out, most part of the hole is located in the thick, intensively deformed zone of tectonic (thrust) fault, which cannot be the object of oil and gas productive accumulation.

For the assessment of reservoir sedimentation processes, regular bathymetric measurements are conducted for determining the reservoir terrain actual elevation model, enabling sediment influx monitoring from the rivers. Continuous surveys have been conducted at the Zhinvali reservoir since 2014. Consistent monitoring facilitates the control and prediction of sediment occurrence, allowing for timely interventions to decelerate or halt the sedimentation process. The technology involves planning cross-sections and using an eco-sounder to measure depth at consistent intervals, covering the entire reservoir area. The results determine the reservoir's actual volume, with variances from the design volume indicating accumlated sediment volume and illustrating live storage reduction dynamics. The article presents bathymetric monitoring data from 2014-2022, using modern instruments and processing, visualization, and analysis methods. The article also provides forecasts and recommendations concerning the sedimentation process.

Authors:   Georgian Technical University, Sakvarelidze Amiran
Published: September 2024

The main constituent part of vertical profile type port-containment buildings is a vertical wall. Buildings are distinguished according to the vertical wall’s underwater structure (built from cement-based composite materials), as: 1. Mass concretes and 2. Mass-giants 1. Port containment buildings from mass concretes. In practice, these buildings utilize conventional masses weighing up to 100 tons and Cyclopean masses exceeding 400 tons. This article addresses the technological aspects associated with constructing containment buildings using conventional concrete masses and Cyclopean masses. Key considerations during the design phase include defining stresses in the building's foundation soil arising from its interaction with the stone bed; construction deformations; strength of construction elements; sustainability of the building and its components. 2. Containment buildings from mass-giants. The fabrication, installation, and transportation processes of mass-giant boxes are examined. The strength of box elements at normal and slanted intersections is determined based on design resistance, accounting for overload coefficients corresponding to various stages, including fabrication, transportation, construction, and operation. Formulas are provided to assess the wall of the box under the force exerted by water pressure, including sum of hydrostatic and dynamic pressures. Additionally, formulas are presented to calculate the vertical and horizontal pressures exerted by bulk material. Bottom of the mass-giant box is designed to withstand loads encountered during both construction and operation phases. Within the boundaries of each plot bottom is treated as a tile attached on all four sides and subjected to transverse loads.

The number of waste tyres is on the increase, because of the growing use of transport vehicles. Almost one trillion waste tyres are generated in the world annually. Established methods of disposal, recycling and re-use of waste tyres have failed to keep pace with generation, proven to be ineffective, cost-intensive and in some cases environmentally unsustainable. This study aims to investigate the effects of utilizing crumbs from discarded rubber as a partial replacement for coarse aggregates in concrete. Rubber crumbs of 10 – 20mm nominal size were produced manually from waste tyres. The rubber crumbs were used to replace 10%, 20% and 30% of coarse aggregates in design concrete of 20N/mm2 target compressive strength. The effects of this material on the slump, water absorption and compressive strength of concrete were examined. The inclusion of rubber crumbs resulted in a decline in the slump of concrete up to 10% relative to the control specimen. Water absorption increased marginally at 10% replacement compared to the control specimen and recorded a maximum value of 0.77% with 30% replacement after 28 days of curing. The compressive strength of the concrete was negatively affected by the rubber crumbs. The maximum value of 13.9N/mm2 was attained at 10% replacement after 28 days of curing. Rubberized concrete with 10% replacement of coarse aggregates can be used for non-structural concrete members such as roof slabs, non–load–bearing partition walls, and roadside barriers. Chemical treatment of rubber crumbs to improve surface adhesion properties should be encouraged.

In Bangladesh, the outbreak of Coronavirus Disease 2019 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first came into light on March 08, 2020. Since then, the scientific communities of the public health sector expressed concern over the issues of heterogeneous clinical features of the disease in the country. The aim of this study is to analyze the heterogeneity of clinical characteristics of 105 COVID-19 cases in Bangladesh from March 08, 2020, to July 31, 2020. The clinical features of 105 COVID-19 cases including demographic information, symptoms, radiological findings etc. were analyzed and compared for both the initial and epidemic phase of COVID-19 outbreak in Bangladesh. Out of 105 cases, more than 20% of cases were completely asymptomatic. For symptomatic patients, the most common symptoms were respiratory stress (>60%) with low-grade fever, cough, and headache. Major X-ray findings were reported as bilateral and patchy opacities (30%). The most common co-morbidities were diabetes (20%) and heart disease (20%). More than 50% COVID19 patients recovered from the infection within three weeks. The prevalence of asymptomatic COVID-19 cases may contribute greatly to the rapid community transmission of the coronavirus in Bangladesh. The clinical outcomes of patients are assumed to be directly related to the co-morbidity and age groups along with gender. This study will significantly contribute to preventing further outbreak of COVID-19 in Bangladesh.

This cross-sectional study was carried out in 8 secondary and tertiary level hospitals of Dhaka and Rajshahi division to assess knowledge attitude and practice among health care waste handlers’ combination of quantitative and qualitative research methods was used, and results were used for triangulation purposes. For quantitative data, a semi-structured questionnaire and observation checklists were developed. For qualitative data, 16 Key Informant Interview (KII) and 4 Focused Group Discussions (FGDs) were conducted. The intervention hospitals have waste storage area and waste management instruction materials are posted on the hospital wall, verbal communication is also maintained for waste management and plastic wastes are shredded. The waste handlers wear gowns during waste handling and use trolley or container to carry the hospital waste. The non-intervention hospitals have no such practices. Doctors of both the groups were aware of the waste management manual and Waste Management Law but they did not practice that law. Practice of maintaining documentation of waste management system was a problem for all the respondents. Respondents of both groups stressed regular monitoring and suggested arranging formal training on HCW management. The hospital Waste Management Team was functionally inactive and not visible. It was recommended that provide training to waste handlers, fill in manpower gap, supply of sufficient logistics, implement internal checklist for monitoring, control number of visitors in hospital and sincerity of the local management could vastly improve the hospital waste management system

Since the issuance of the Regulation of the Republic of Indonesia National Police No. 8 of 2021 concerning Handling of Criminal Acts Based on Restorative Justice, the National Police has increasingly emphasized its policy to implement Restorative Justice. Restorative Justice is a step to resolve problems outside of retributive law enforcement mechanisms. In restorative justice, the principle of ultimum remedium applies, where criminalization is the last alternative for punishing a crime. Therefore, there needs to be an in-depth study for Bhabinkamtibmas members regarding the implementation of Restorative Justice. The goal is for Bhabinkamtibmas members to be more professional in carrying out their duties as fosterers of public security and order, especially related to the implementation of Restorative Justice in resolving criminal cases in their environment. The method used is through interactive discussions on various problems encountered in the field and the delivery of learning materials by Abdimas. Based on the results of the implementation during PkM, there was an increase in knowledge among Bhabinkamtibmas members, especially in-depth study of the implementation of Restorative Justice, communication and conflict management. It is hoped that this can improve the professionalism of Bhabinkamtibmas members in implementing Restorative Justice in accordance with their field of duty.

Inclusive education at Vocational High Schools that offer Inclusive Education (SMK-PPI) aims to provide equal access to learning for students with special needs (SBK). This community service program is designed to develop an innovative Deep Learning-based learning model to enhance inclusivity and the quality of education at SMK-PPI. The program begins with a needs identification phase, where observations and interviews are conducted at schools that accommodate SBK to understand existing challenges and identify gaps in the current teaching methods. Collaboration with the school and community stakeholders is essential to align the program's objectives and tailor the learning plan to meet specific needs. Intensive training for SMK-PPI teachers is the initial step in implementing the program, including the introduction of Deep Learning technology and the development of inclusive teaching strategies. The Deep Learning-based learning model is then implemented in classrooms involving SBK, focusing on personalized learning and using technology to meet individual students' needs. Data is continuously collected through observations, interviews, and surveys to evaluate the program's effectiveness. The evaluation results show that the model successfully increased student engagement, accessibility, and learning outcomes. Reflection and improvement are conducted based on feedback from all involved parties, ensuring that this learning model can be sustainably adopted by other schools. This program is expected to make a significant contribution to strengthening inclusive education at SMK-PPI and helping all students reach their full potential.
