Fatigue Behavior of Heavy-Haul Railway Prestressed Concrete Beams Based on Vehicle-Bridge Coupling Vibration
Authors: Song Li , Liu Ran , Cui Chenxing , Yu Zhiwu , Zhang Wenchang
Published: April 2022

Due to the demand for increasing trainload and enhancing some existing heavy-haul railways, the low reserve value of bearing capacity is a problem for the 32 m-span simply supported beam. The fatigue behavior of prestressed concrete beams in a heavy-haul railway loaded by 33 t and larger axle weight of trains was experimentally investigated. The experimental results of the fatigue behaviors, including fatigue deformation, crack propagation behavior, and strains of classical materials were obtained and analyzed. A fatigue behavior assessment model was established to investigate the residual stiffness and yield point degradation of the beams loaded by the trainload. The effects of train fatigue cycles and prestress loss on the residual stiffness and yield point degradation models of the beams were analyzed. The results indicated that the crack development process had three stages during the fatigue process: the derivative stage, gradual development stage, and fatigue failure stage. Trainload was the main external factor influencing the fatigue behavior of prestressed concrete beams. The increase in trainload accelerated the degradation rate of the residual stiffness of the beams and yield point, reducing the fatigue life. The prestressing strand was primarily used to delay the concrete cracking in the tension zone. When the beam was not cracked, the prestressed concrete beam showed good fatigue performance, and the degree of prestressing did not affect the fatigue life of the beams. When the maximum fatigue load exceeded the cracking load of the beam, prestress loss in beams became a critical issue that accelerated the degradation rate of fatigue strength and reduced fatigue life. The higher the fatigue damage degree, the more pronounced the effect of prestress loss on the fatigue strength of the beams. The fatigue failure of prestressed concrete beams occurred in the bottom tensile steel bar. Therefore, when the trainload of a heavy-haul railway is greater than the cracking load of the beam, it is recommended to strengthen the beam by prestressing and strictly control the trainload to avoid yield failure.

Published: April 2022

Under the background of climate change, the steel industry is considered one of the least eco-friendly industries. Flax fiber-reinforced polymer (FFRP) is an emerging sustainable alternative to steel reinforcement bar; however, its application is much restricted due to its interior material properties. This paper proposed a novel way to form closed-shape stirrups with FFRP, which is suitable for replacing steel stirrups. A multi-disciplinary investigation was conducted concerning the structural and environmental performance of FFRP stirrups in reinforced concrete (RC) beams. Seven specimens were tested under a three-point bending load. The FFRP stirrups substantially increased the shear capacity and ultimate vertical displacement by 77% and 74%, respectively, and shifted brittle failure to ductile failure. The closed-shape stirrups avoided the stress concentration and increased the utilization of FFRP tensile capacity to over 80%. Decreasing the spacing of FFRP stirrups effectively increased the shear capacity and ductility; increasing the width or layer of FFRP stirrups improved ductility only. A life cycle assessment (LCA) was later performed to evaluate and compare the environmental performance of steel, FFRP, and carbon FRP stirrups. As compared to carbon FRP and steel ones, FFRP stirrups substantially decreased the global warming and fossil depletion potential by over 60%. The main contributors to the environmental impacts of FFRP stirrups were the heavy metal released into the water and terrestrial environment during the cultivation process.

Authors: Słomka-Słupik Barbara , Labus Krzysztof
Published: April 2022

Concrete tanks, in coke wastewater treatment plants, are exposed to aggressive wastewater with high ammonium and chloride content, deteriorating the concrete binder. Due to this, toxic compounds may migrate to the environment. The results of the experimental work presented confirmed the changes in the phase, microstructure and concentration of chlorides caused by the penetration of NH4Cl into the hardened cement paste in dry conditions. Geochemical modeling of the interactions between the aggressive solution, the cement stone matrix and the pore water was performed in order to track the destruction process effects. The results are useful for condition assessment of the structures operating under occasional immersion.

Published: April 2022

Операции на лимфаденоидном глоточном кольце являются наиболее распространенными в детской лор-практике. Гипертрофия небных миндалин (ГНМ) может существенно ухудшать качество жизни пациента, так как вызывает затруднение носового дыхания, нарушение глотания, синдром обструктивного апноэ сна. При ГНМ в качестве хирургического метода лечения применяются тонзиллэктомия (ТЭ) и тонзиллотомия (ТТ). В последнее время в Республике Беларусь после периода достаточно сдержанного отношения к ТТ данный метод получил широкое распространение. Учитывая значимость лимфоидной ткани в детском возрасте, следует с большой ответственностью оценивать показания к хирургическому вмешательству. В статье рассмотрены показания и противопоказания к ТТ, современные методы ТТ, приведены случаи из практики с редкими осложнениями операции.

Operations on the lymphadenoid pharyngeal ring are the most common in the ENT practice. Hypertrophy of palatine tonsils (HPT) can significantly worsen the quality of life of the patient, as it causes difficulty in nasal breathing, impaired swallowing, obstructive sleep apnea syndrome (OSAS). With HPT, tonsillectomy (TE) and tonsillotomy (TT) are used as a surgical method of treatment. Recently, in the Republic of Belarus, after a period of fairly restrained attitude to TT, this method has become widespread. Given the importance of lymphoid tissue in childhood, it is a great responsibility to evaluate indications for surgical intervention. The article discusses the indications and contra-indications of TT, modern methods of TT, the cases from practice with rare complications of the operation are given.

Los enfermos y la enfermedad, un binomio que requiere del estudio de los exámenes de laboratorio y la correcta interpretación de los resultados, los cuales pueden estar sujetos a errores de procesamiento por descalibración de los equipos de laboratorio ya sea a partir de los errores humanos o en la toma de muestras. Es así que se hace necesario el cotejo con la historia clínica del paciente, por la cambiante evolución de la enfermedad y por la concurrencia de otras patologías o cuadro de fondo que pudiera enmascarar el verdadero cuadro patológico. Se entiende entonces la importancia de considerar todas las circunstancias que rodean al enfermo, como los antecedentes patológicos (datos obtenidos del historial) los que sirven para una correcta interpretación del cuadro que aqueja al enfermo. Los exámenes de laboratorio son pruebas basadas en el estudio de muestras de fluidos y tejidos corporales permiten determinar estados biológicos y bioquímicos. Los datos obtenidos se reportan en forma escrita o por virtual, previo registro en el gabinete de trabajo. Éstos sirven para confirmar o descartar diagnósticos, determinar y controlar tratamientos e identificar la evolución de eventos fisiopatológicos. Los valores normales dependen del método, los reactivos químicos utilizados, la toma de la muestra, la conservación, su manipulación correcta y el cuidadoso traslado que evite la contaminación. Una práctica común al momento de atender pacientes en los servicios de salud consiste en que el personal médico solicite los exámenes de laboratorio. Por su parte, el personal de enfermería se encarga de acompañar al paciente para el cumplimiento de lo solicitado, la toma de muestras. El personal de laboratorio se encarga de la toma y apenas se tienen los resultados la enfermera toma conocimiento debe saber interpretarlos con la finalidad de comunicar de manera urgente al personal médico. Dependiendo de las circunstancias, si representa una emergencia o no, para tomar acciones conjuntas con los otros profesionales de salud, de manera que se pueda revertir el peligro y coadyuvar a mantener la homeostasis del enfermo. Es así que se presenta este manual de consulta rápida como herramienta tanto para los profesionales como los estudiantes y puedan realizar una interpretación fácil de los exámenes de laboratorio.
Hygienic Assessment of the Iron Content of Tap Water in Administrative Centers in the North of the Tyumen Region
Authors: Lapenko VV , Bikbulatova LN  , Minyaylo LA , Kharkov VV
Published: April 2022

Background: Introduction: Iron is an essential mineral for humans. Its excessive dietary intake has no adverse health effects but high exposure to inorganic iron can induce oxidative stress. Increased Fe concentrations in tap water in the north of the Tyu­ men Region are attributed, on the one hand, to natural characteristics of its source and, on the other hand, to iron released by deteriorated water pipes. In the administrative centers of this region, high-quality reagent-free water treatment is carried out but tap water quality is largely influenced by the condition of water supply networks with the wear indicators of 26.3 % and 82.1 %, in the cities of Khanty-Mansiysk and Salekhard, respectively. Objective: To compare iron contents in tap water in Khanty-Mansiysk and Salekhard against its maximum permissible concentration and to assess health risks from exposure to this mineral in drinking water.
Materials and methods: Fifty tap water samples were taken in each of the two administrative centers of the Tyumen Region (Khanty-Mansiysk, Khanty-Mansi Autonomous District – Yugra, and Salekhard, Yamalo-Nenets Autonomous District) for a
spectrophotometric analysis of iron. The results were evaluated according to regulations SanPiN 1.2.3685–21, Hygienic stan­ dards and requirements for ensuring safety and/or harmlessness of environmental factors to humans, introduced by Decree No. 3 of the Chief State Sanitary Doctor of the Russian Federation of January 28, 2021. Non-carcinogenic risks were assessed in accordance with Guidelines R 2.1.10.1920–04, Human health risk assessment from environmental chemicals.
Results: Iron levels in tap water were found to be significantly lower in the city of Khanty-Mansiysk compared to Salekhard (p = 0.002) with excessive Fe concentrations established in 10 % and 66 % of the samples taken in those cities, respectively. Ac­ cordingly, the Fe-related hazard quotient in Khanty-Mansiysk was almost twice as low (0.73) as in Salekhard (1.52) indicating increased likelihood of a toxicological response to the chemical in the latter.
Conclusions: In order to supply residents with drinking water of optimal quality and reduce potential health risks, it is neces­ sary to replace worn out distribution networks, organize and ensure proper monitoring of water quality, duly implement the
Regional Clean Water Project and assess its effectiveness.
Problems of Treating Patients with Diseases of the Circulatory System in the Perception of Medical Workers: Experience of the Sverdlovsk Region
Authors: Leontiev SL , Mikhailova DO , Anufrieva EV , Kazantsev VS , Kuzmin KV
Published: April 2022

Introduction: Consideration of the problems of prevention, diagnosis and treatment of patients is associated with the study
of the subjective opinion of medical workers and the assessment of their role in the development of population health care.
The objective of the study was to study the opinion of medical workers of the Sverdlovsk Region on the availability and
quality of care for patients with diseases of the circulatory system.
Methods: In February – March 2020, we conducted a questionnaire-based survey of 303 randomly chosen health professionals, mainly general practitioners and cardiologists, working in urban and rural health care facilities of the region.
Results and discussion: The majority of the respondents believed that the patient’s adherence to prescribed treatment and rejection of bad habits contributed the most to mortality reduction. Standards of medical care and Russian clinical guidelines
were reported as the most significant factors in making decisions on patient management. The respondents rated their own competence level quite low in determining the need for medical interventions. When assessing the quality of the follow-up care, the respondents reported regular monitoring of only four parameters (electrocardiogram, platelet and lipoprotein levels, and body weight), explaining the incompleteness of the process by limited opportunities for a proper examination in medical facilities. The health care providers noted the observance of sequencing (routing) in provision of medical care and the possibility of obtaining the necessary medicines; yet, almost half of the respondents specified that the recommended clinical examinations at the outpatient stage of treatment were conducted only in part. When assessing the effectiveness of work of healthcare centers for patients with chronic heart failure, positive changes were noted by 25 % of the respondents while 20 % reported a reduction in waiting time for high-tech care.
Conclusion: The study of the opinion of medical workers helps reveal contradictions in rendering health services. Possessing a well-formed professional mindset, they reflect official (insider’s) views on the problems of the healthcare system in their
assessments, but being involved in communication with patients, they express philistine opinions.

Приведены результаты исследования влияния анионных поверхностно-активных веществ на физико-химические и биохимические процессы в экосистеме малого эвтрофного водотока методом лабораторного моделирования. Установлено, что анионные поверхностно-активные вещества подавляют процессы нитрификации пропорционально их содержанию в воде, миграция фосфатов из донных отложений интенсивно происходит в интервале концентраций 0,02–0,1 мг/дм3, что соответствует уровню загрязнения вод исследуемого водотока. При концентрации анионных поверхностно-активных веществ от 1,2 до 4 мг/дм3 в модельном растворе миграция фосфат-ионов из донных отложений прекращалась. С использованием корреляционного анализа изучено влияние состава воды и донных отложений на подвижность фосфат-ионов в экосистеме водотока.

The results of studying the impact of anionic surfactants on the physicochemical and biochemical processes in the ecosystem of a small eutrophic watercourse by laboratory modeling are presented. It has been established that anionic surfactants inhibit nitrification processes in proportion to their concentration in water; migration of phosphates from bottom deposits occurs intensively in the concentration range of 0.02–0.1 mg/dm3, which is equivalent of the level of the studied watercourse pollution. At the concentration of anionic surfactants from 1.2 to 4 mg/dm3 in the model solution, the migration of phosphate ions from the bottom deposits deceased. Correlation analysis was used to study the effect of the composition of water and bottom deposits on the mobility degree of phosphate ions in the watercourse ecosystem.
Improving broadband absorption and transparent properties for microwave metamaterial via stimulating bimodal effect with induced water substrate
Authors: Zhou Qian , Gu Shengyue , Xue Bei , Ye Fang , Fan Xiaomeng
Published: April 2022

In this paper, a frequency selective microwave absorber is designed and demonstrated with water as the substrate layer, which realizes >90% absorption in the frequency range of 7.3–20 GHz and 73.6% light transparent in the spectrum range of 400–800 nm. The improved absorption is believed to be attributed to the synergy between the intrinsic resonance of the ITO metasurface and the new resonance excited by the substrate water layer. Particularly, the light transparence of the absorber is improved with the introduced water layer. Therefore, the proposed absorber shows excellent comprehensive performances for high optical transparent microwave broadband absorbers.

Hydrogenated amorphous silicon is a well known detector material for its radiation resistance. This study concern 10 µm thickness, p-i-n and charge selective contacts planar diode detectors which were irradiated with neutrons at two fluence values: 1016 neq/cm2 and 5 x 1016 neq/cm2. In order to evaluate their radiation resistance, detector leakage current and response to X-ray photons have been measured. The effect of annealing for performance recovery at 100°C for 12 and 24 hours has also been studied. The results for the 1016 neq/cm2 irradiation show a factor 2 increase in leakage current that is completely recovered after annealing for p-i-n devices while charge selective contacts devices show an overall decrease of the leakage current at the end of the annealing process compared to the measurement before the irradiation. X-ray dosimetric sensitivity degrades, for this fluence, at the end of irradiation but partially recovers for charge selective contacts devices and increases for p-i-n devices at the end of the annealing process. Concerning the 5 x 1016 neq/cm2 irradiation test (for p-i-n structures only), due to the activation occurred during the irradiation phase, the results were taken after 146 days of storage around 0° C when a self-annealing effect may have occurred. Nevertheless the results shows a degradation in leakage current and x-ray sensitivity which changes very little after annealing.

Applying Two Equidistant Samples-based-PLL on Unbalanced Three-Phase Signals with DC Offsets
Authors: Ahmed Hafiz , Ushirobira Rosane , Efimov Denis
Published: April 2022

Delayed signal cancellation (DSC) is a popular method to separate the fundamental frequency positive- and negative-sequence components from unbalanced three-phase signals. Conventional DSC can separate the sequence components using a quarter-cycle delay. Fast DSC tools can achieve the same with less than a quarter-cycle delay. However, neither conventional nor fast DSC can handle DC offset without requiring additional delayed signals. This letter addresses this issue by proposing a modified DSC to estimate the sequence components with DC offset rejection and having arbitrarily fast convergence speed, i.e., low memory requirement. Two equidistant delayed samples of the measured grid voltages/currents are required to implement the proposed technique and can easily be applied in a phase-locked loop (PLL). Comparative experimental results demonstrate the suitability of the proposed approach over other DSC methods.

An Interpretable Intelligent Model for Predicting Readmission Risk Features in Diabetes Patients
Authors: Guo Changfeng , Zhou Haoran , Tong Runzhe , Farid Farnaz
Published: April 2022

Hospital readmission of Diabetes patients is a persistent burden on the healthcare industry. Artificial Intelligence (AI) based Machine Learning (ML) techniques offer the potential to predict readmission rates and related risk features for diabetic patients. However, complex machine learning-based solutions are often not interpretable and, thus, hard to understand for the relative parties. To this end, this study designs and implements an interpretable model to predict readmission rates and identify the risk features of readmission of diabetes patients. The model applies a range of explainable visualization techniques such as the permutation importance plot, partial dependence plot (PDP), SHapley Additive exPlanations (SHAP), and interpretable classifiers on a publicly available dataset from US hospitals. The bagging random forest model shows the best results with 89\% accuracy and 67\% precision. The interpretable visualization techniques reveal the number of inpatient admissions and emergency visits in a year as the two most critical risk features for the readmission rate of diabetic patients.
The editions of folklore song in 1917—1918 years in special fund of the Book Chamber of Ukraine: bibliologycal research
Authors: Khailo Aliona
Published: April 2022

The article examines the publications of folk songs of 1919—1921, which are stored in the special fund of the Book Chamber of Ukraine — an inseparable part of the State Archive of Printing of 1917—1976, which contains literature banned by censors (the total number of publications of the special fund — 17 236). Both separate collections devoted entirely to the publication of folklore works and the publication of folk texts included in poetry collections with artistic author's texts are analyzed. In addition, taking into account the peculiarities of the period under study, the exploration also considered songs, the lyrics of which can be called "fakelore", or, in other words, pseudo-folklore.
17 editions of song texts from 1919 to 1921 were selected for the study, among which only three titles were devoted to traditional Ukrainian folklore: "Ten Ukrainian Folk Songs: Accompanied by a Piano" (1921), arranged by F. Blumendfeld; collection "Ukrainian folk songs (a capella): for mixed choir" (issue 4, 1920), compiled and arranged by P. Boychenko, and "School collection of Ukrainian folk songs for primary schools" (1919), compiled by S. Dremtsov. The remaining 14 copies are collections of revolutionary and workers' songs: 3 editions of "Battle Songs of the Communists" (all 1919); "Songs of Struggle to the End" (1919); "Workers' Liberation Songs" (1919); "Songs of the Revolution" (1919); "Battle Songs of the Revolution" (probably 1919); "Battle Songs of the Communists" (probably 1919); "Collection of Revolutionary Songs" (1920); "Revolutionary Songs" (1921, 2nd edition); "Under the Red Banner: Workers' Revolutionary Songs" (1920).

Authors: Senchenko Mykola
Published: April 2022

The article deals with the new tasks of mass media and scientific libraries in the conditions of organizational warfare with the use of "soft power" of books and mass media, psychophysical and biological weapons.
It was found that organizational war is a war of a special type: financial, economic, cultural, informational, political, organizational.
Organizational warfare is conducted with the use of organizational weapons (OW), the components of which are: organizational information, organizational finance, organizational management, organizational educational and other types of equipment.
The main tasks of the army are to disorient the behavior of the enemy population, strengthen the centrifugal trends in his society, exacerbate contradictions in the system of cultural codes, impose unacceptable for its economy development programs, form situational social groups that will require radical reform of ideological and ideological target states.
It is noted that organizational wars are conducted according to social-communication algorithms of transformation of social systems. Currently, the best-known and most popular among the G-oligarchs algorithm for targeted management of social processes is an algorithm based on the doctrine of "controlled chaos".
It is emphasized that today the issues related to the study of book collections for a constructive organizational war are extremely relevant. The role of scientific libraries as think tanks in the conditions of organizational war is determined.
History pages and contemporary Ukrainian Book Holidays in Canada
Authors: Solonska Natalia
Published: April 2022

One of the forms and means of preserving national identity, Ukrainian culture, language, promoting the mother-tongue book in Canada is the traditional autumn Ukrainian Book Festival. It characterizes not only the educational and communication activities of scientific and cultural institutions, libraries, reading rooms, museums of the diaspora, its public, religious organizations, colleges and schools in Canada; but also the level of development of the book industry in it; social situation in the country, in the world; the attitude of its government and official circles not only to the ethnic book but also to immigrants; peculiarities of diaspora readership and its specificity (in particular, change of English-speaking everyday life into the mother-tongue environment during the event — psychological adaptation, possibility to speak freely, easily in the language of the historical homeland; feeling or not feeling of unity with one's nation); communication in society; circle of reading of its members; reader's requirements; spiritual and informational needs; the situation of publishers and bookstores; culture and level of book business (trends in product design, printing, paper, etc.); book priorities (traditional, paperback and electronic; book in your native language or country of residence); modern technologies for preparing book exhibitions, etc. And that is very fundamental. The Ukrainian Book Festival promotes the preservation of the mother tongue and the links between immigrants and their descendants with their historical homeland.
The peculiarity and difficulty of the presentation of Ukrainian books, authored by representatives of the ethnic community in Canada, is that the diaspora is surrounded by a foreign language environment and perceives the word, information only in its own language. However, members of the Ukrainian diaspora can and do participate in holidays (festivals, fairs, etc.) dedicated to the book in the language of the country in which they reside.
Canada has established itself as a country that has a multiculturalism policy that gives a real opportunity to develop freely the culture of all ethnic groups living in it.
Considering that the Ukrainian Diaspora centers exist in many countries, in our view, it is advisable to set up an International Day of the Ukrainian Language, on the model of other countries.

The need to determine the strategy of functional and structural transformations of the library's representation in a digital environment was stated. The methodological basis of such transformations was substantiated. Its essence is to provide a fundamental systemic deepening of integration interaction of library's information processes with research, science publishing and review-analytical technologies. The need to establish a key construct (concept, approach), that will act as the core of synergies in library and research activities, was noted. The imperative of the library's transition from the "catching up" to the "leading" development model was chosen as such a construct. It was emphasized that the library can no longer consider the introduction of information and communication technologies, tested in other areas, as a tool that will allow it to keep up with the times. A new approach to the systemic transformation of the library, which will correspond to the concept of a "leading" development model, is needed. The synergetic principles of interaction between library and research activities were chosen as the basis for this concept. The presence of significant results of using the synergetic approaches in the implementation of intra-library technology was stated. The need for their further development for integration with research, publishing, scientific and analytical processes and technologies was noted. This vector of transformations of the library and related environments will ensure the preservation of the library's identity and help increase its role and status in society.
