Published: May 2024

Background: Recent studies have indicated that heart failure (HF) with preserved ejection fraction (HFpEF) within different left ventricular ejection fraction (LVEF) ranges presents distinct morphological and pathophysiological characteristics, potentially leading to diverse prognoses. Methods: We included chronic HF patients hospitalized in the Department of Cardiology at Hebei General Hospital from January 2018 to June 2021. Patients were categorized into four groups based on LVEF: HF with reduced ejection fraction (HFrEF, LVEF ≤40%), HF with mildly reduced ejection fraction (HFmrEF, 41% ≤ LVEF ≤ 49%), low LVEF-HFpEF (50% ≤ LVEF ≤ 60%), and high LVEF-HFpEF (LVEF >60%). Kaplan‒Meier curves were plotted to observe the occurrence rate of endpoint events (all-cause mortality and cardiovascular mortality) within a 2-year period. Cox proportional hazards regression models were employed to predict the risk factors for endpoint events. Sensitivity analyses were conducted using propensity score matching (PSM), and Fine-Gray tests were used to evaluate competitive risk. Results: A total of 483 chronic HF patients were ultimately included. Kaplan‒Meier curves indicated a lower risk of endpoint events in the high LVEF-HFpEF group than in the low LVEF-HFpEF group. After PSM, there were still statistically significant differences in endpoint events between the two groups (all-cause mortality p = 0.048, cardiovascular mortality p = 0.027). Body mass index (BMI), coronary artery disease, cerebrovascular disease, hyperlipidemia, hypoalbuminemia, and diuretic use were identified as independent risk factors for all-cause mortality in the low LVEF-HFpEF group (p < 0.05). Hyperlipidemia, the estimated glomerular filtration rate (eGFR), and β-blocker use were independent risk factors for cardiovascular mortality (p < 0.05). In the high LVEF-HFpEF group, multivariate Cox regression analysis revealed that age, smoking history, hypoalbuminemia, and the eGFR were independent risk factors for all-cause mortality, while age, heart rate, blood potassium level, and the eGFR were independent risk factors for cardiovascular mortality (p < 0.05). After controlling for competitive risk, cardiovascular mortality risk remained higher in the low LVEF-HFpEF group than in the high LVEF-HFpEF group (Fine-Gray p < 0.01). Conclusions: Low LVEF-HFpEF and high LVEF-HFpEF represent two distinct phenotypes of HFpEF. Patients with high LVEF-HFpEF have lower risks of both all-cause mortality and cardiovascular mortality than those with low LVEF-HFpEF. The therapeutic reduction in blood volume may not be the best treatment option for patients with high LVEF-HFpEF.

Cardiovascular disease (CVD) diagnosis and treatment are challenging since symptoms appear late in the disease’s progression. Despite clinical risk scores, cardiac event prediction is inadequate, and many at-risk patients are not adequately categorised by conventional risk factors alone. Integrating genomic-based biomarkers (GBBM), specifically those found in plasma and/or serum samples, along with novel non-invasive radiomic-based biomarkers (RBBM) such as plaque area and plaque burden can improve the overall specificity of CVD risk. This review proposes two hypotheses: (i) RBBM and GBBM biomarkers have a strong correlation and can be used to detect the severity of CVD and stroke precisely, and (ii) introduces a proposed artificial intelligence (AI)—based preventive, precision, and personalized (aiP3) CVD/Stroke risk model. The PRISMA search selected 246 studies for the CVD/Stroke risk. It showed that using the RBBM and GBBM biomarkers, deep learning (DL) modelscould be used for CVD/Stroke risk stratification in the aiP3 framework. Furthermore, we present a concise overview of platelet function, complete blood count (CBC), and diagnostic methods. As part of the AI paradigm, we discuss explainability, pruning, bias, and benchmarking against previous studies and their potential impacts. The review proposes the integration of RBBM and GBBM, an innovative solution streamlined in the DL paradigm for predicting CVD/Stroke risk in the aiP3 framework. The combination of RBBM and GBBM introduces a powerful CVD/Stroke risk assessment paradigm. aiP3 model signifies a promising advancement in CVD/Stroke risk assessment.

Open Access in Language Testing and Assessment: The Case of Two Flagship Journals
Authors: Liu Meng , Al-Hoorie Ali H. , Hiver Phil V.
Published: May 2024

This study is a systematic examination of the open access status of research in two flagship language testing and assessment journals: Language Testing and Language Assessment Quarterly. Coding and analysing 898 articles, we investigated a) the prevalence of open access in four aspects – open manuscripts, open materials, open data, and open code, and b) the relationship between open access and various characteristics of research, tests, and researchers. Our study revealed a positive trend in the adoption of open access over time, with open manuscripts and materials showing notable increases. Open code and data have remained scarce, though with a recent uptick from a low base. Notably, logistic regression results suggest inequitable participation in open access as authors from the Global South were less likely to have open manuscripts. Recognising the potential role of flagship journals as trend and standard setters, we call on the field to a) shift toward more equitable open access models, b) balance intellectual property concerns with validation needs, c) recognise open code and open data with protected access via dedicated badges, and d) adopt Research Transparency Statements, a new reporting structure inclusive of methodological and epistemological differences in open research practices.
The Use of AI by Election Campaigns
Authors: Foos Florian
Published: May 2024

The rapid development of artificial intelligence and especially large language models has now reached a stage, where generative AI is both powerful and accessible enough to be used at scale in election campaigns, at least in principle. In this paper, I outline some of the potential legal uses of AI by election campaigns: Generative AI already cuts costs for campaigns by assisting them at drafting communication such as fundraising emails or text messages. In the near future, the use of generative AI can potentially transform the way campaigns interact with voters by allowing them to conduct AI-to-voter conversations in many languages, and potentially at scale. While campaigns have personalised and tailored digital communication before the advent of mass-accessible generative AI-tools, the ability for LLMs to engage dynamically with information and arguments provided by voters is new and, potentially, transformative. The question is whether AI-to-voter communication via peer-to-peer messaging is scalable, and the answer depends on how access to personal data is regulated, which varies between countries and regions. If campaigns are legally able to access personal contact data, AI-to-voter communication is potentially disruptive, and could impact the political playing field in the mid-term.
DEVELOPMENT OF A SYSTEM FOR THE CHARACTERIZATION OF LOW POWER SUPERCAPACITORS
Authors: Olarte Ortiz Oscar , Moreno Celis Ingrid Johanna , Cely Quesada Franky Yoan , Retamoso Llamas Alonso de Jesús , Gonzalez Fabio Alfonso
Published: May 2024

Supercapacitors are presented as a viable energy, technical, and economic alternative in electrical energy storage and supply applications. This non-linear electrochemical device needs specific electrical models to represent its real behavior. Only one resistance value and one capacitance value are found in the data sheets provided by the supercapacitor manufacturers, which do not allow any of these electrical models to be conceived. This work presents the simulation and assembly of a simple, economical, efficient, and easy to implement system to characterize low power supercapacitors. Said characterization is based on parameterizing the passive elements of a selected supercapacitor model. An algorithm for the identification of parameters implemented in Matlab is proposed, which is based on iterative methods and laboratory tests (charge and discharge of the supercapacitor). The conception of a genetic algorithm of our authorship is also proposed as one of the iterative solution methods. The results obtained are satisfactory, and a successful experimental model for each supercapacitor under study was obtained.
Comparing Auditory, Haptic, and Combined Auditory-haptic Lane Departure Warnings: A Systematic Review and Meta-analysis
Authors: Nees Michael A.
Published: May 2024

Lane departure warnings have become a common feature in vehicles and are recommended by safety regulators. Since visual warnings can be missed during the visually-demanding task of driving, the auditory and haptic modalities are preferred for delivering lane departure warnings. A systematic review of the literature was conducted to identify experiments that have compared the efficacy of auditory, haptic, or combined auditory-haptic lane departure warnings. Of 841 candidate articles, 10 experiments were identified that contained data on the comparisons of interest. Network meta- analysis was used to compare the three treatments of interest. Results of analyses showed significantly slower responses to auditory versus multimodal and auditory versus haptic LDWs. Since fast responses to lane departures are desirable, the current analysis of available evidence suggested that haptic or multimodal (combined auditory and haptic) LDWs should be preferred to auditory only LDWs. Still, results were characterized by high heterogeneity, and a wide range of plausible findings in future research cannot be ruled out based on currently available evidence.
The dissociative mechanism of change in wilderness and adventure therapy; Psychological harm and possible malpractice
Authors: Pringle Graham , Dubon Soren , Mater Jamie , Keech Catherine , Danylchuk Lynette , Dobud Will
Published: May 2024

Wilderness and adventure therapy (WT, AT) have employed cognitive or adaptive dissonance and involuntary treatment for decades. Cognitive dissonance occurs when people are faced with situations that do not confirm their expectations. Past WT participants have protested that involuntary, inescapable and harsh conditions harmed them through PTSD and dissociation. We compare dissonance and dissociation using a critical realist and argumentative research process using publicly available data. We argue that dissociation is a response, recorded both in the design of WT and in participant statement, that is mistaken for dissonance. Deliberate use of forced cognitive dissonance during involuntary treatments are also the conditions that may cause dissociation. Therefore, planning to enforce cognitive dissonance during coercive WT or AT is likely to be harmful and, knowing of this potential, may be regarded as malpractice.

Authors: Bhattarai Achyutananda
Published: May 2024

This research examines the domestication and foreignization translation strategies used in the Constitution of Nepal 2015 analyzing official and unofficial translations of the constitution. How these translation strategies have been used to convey the source language (SL) message to the target language (TL) readers despite the linguistic and cultural differences is searched. The corporate author’s official translation of the Law Book Management Board (LBMB) and the unofficial translation by the International Institute for Democracy and Electoral Assistance (IDEA) have been used to collect, analyze, and interpret data. Venuti’s translation theory of domestication and foreignization is used for the theoretical framework. The objective of this research is to find the effectiveness of these two strategies for the translation of the Nepali constitution. This research finds both the domestication and the foreignization translation strategies have been used in parallel for the translation of the Constitution of Nepal 2015. It concludes that using both strategies simultaneously as complements of one another increases the comprehensibility of the translation.
Magic Realism in Rabindra Sameer's Mrityuko Aayu
Authors: Subedi Yubaraj
Published: May 2024

This article analyzes the novel Mrityuko Aayu in the light of Magic Realism. Applying magic realism is methodological approach for critical analysis of the novel in this article. It follows interpretive textual analysis. Free translation has been used while taking the citation from the novel. I have drawn the conclusion that the novel is a magic realist novel as it has introduced innovative style of narrating the story. The story begins from the death of the protagonist, but he is capable of seeing everything even after the death. It has blended mundane and supernatural, ordinary and extraordinary and real and fantastical elements in an unquestionable way. The novel's extracts are analyzed within five parameters that include fantastical elements, real world setting, incorporation of myth, meta-fiction and social/ political critique. Even after the death of the protagonist, the story moves ahead from the spirit's perspective. The spirit is capable of seeing, feeling and experiencing everything. The readers accept all such actions and happenings as normal without questioning the reliability of them and feel sorry for his painful and pathetic condition. Therefore, the writer is successful in using magic realism in the novel. It is hoped that this article will encourage researchers to study other works of fiction from the point of view of Magic Realism.

Authors: Saquib Mohammed , Mehta Bhavya , Bhargava Rahul , Malik Anu
Published: May 2024

Introduction: In the sub-continent, there is a huge discrepancy between the cornea collected and the ever-increasing demand. Lack of awareness, faulty perceptions, and unwillingness to donate corneas are the major hurdles. 
Objectives: To assess the level of awareness among doctors, students, and paramedics in a teaching hospital.
Materials and methods: An analytical cross-sectional, pre-tested, study design assessed the awareness, knowledge, and attitude among health care workers (medical students, nurses, doctors, and paramedics) in the context of eye donation through a administered self-administered semi-structured questionnaire. 
Results: In our study, 692 (57.7%) of the respondents were aware that the ideal time for donation was within six hours of death. Our study revealed that 875 (72.9) of the respondents were willing to donate their eyes; out of these 305 (25.4%) were MBBS students and 223 (18.6%) were nursing students, (Chi-square tests, p <0.001). Six-hundred and twenty-five (52.1%) respondents knew that the nearest eye bank should be contacted if they or any of their family members wished to donate their eyes. However, only 90 (7.5%) of the respondents’ family/ relatives had donated his/her eyes. A significant association between knowledge of eye donation and the age, gender, religion, or marital status and knowledge of eye donation of participants was observed.
Conclusion: The study highlights the need for creating awareness about eye donation among doctors, medical students, and paramedics, who can be an effective channel for planning, educating, and motivating the public to pledge for eye donation.

Introduction: Accurate refractive error assessment is the first and the most important step of ocular examination. A reliable screening method of refractive status is important for early detection and prevention of blinding complications of uncorrected refractive error.
Objectives: To evaluate the comparability of astigmatism measured by an auto-refractometer (URk-800F) with the measurements of the gold standard anterior segment optical coherence tomography (AS-OCT).
Materials and methods:This cross-sectional observational study was conducted in a tertiary eye centre in Kathmandu from February 2023 to June 2023. A total of 100 patients with best corrected visual acuity of ≥ 20/20, spherical refractive error with cylindrical error of more than and equal to -0.75 and no pathology detected on slit lamp examination were taken by consecutive sampling method. Ethical approval was taken for the study. The data were entered into Microsoft Excel and analysed using Bland-Altman analysis.
Results: The mean cylindrical power and axis was -2.33 D and 88 degrees for the right eye and -2.32 D and 122 degrees for the left eye respectively, as measured by MS-39 AS-OCT. For URK 800-F Auto-refracto Keratometer, the mean cylindrical power and axis was -2.31 D and 89 degrees for the right eye and -2.27 D and 124 degrees for the left eye. 
Conclusion: The findings of this study conclude that an auto-refractometer can be used as an effective tool for identification of spherical refractive error as well as measurement of accurate cylindrical power and cylindrical axis in low resource primary care settings.
POWERS OF THE NATIONAL REVENUE ADMINISTRATION WITH REGARD TO TEMPORARY ATTACHMENT OF MOVABLE PROPERTY: LEGISLATIVE ASPECTS
Authors: Kłosowiak Miłosz
Published: May 2024

The amendment of the Act on the National Revenue Administration, in force since 1 January 2022, gave officers the right to temporary seizure of movable property. As a part of the ‘Polish Deal’, amendments were made to the Act of 16 November 2016 on the National Revenue Administration and added in Section V Chapter 1c ‘Temporary attachment of movable property’, as well as Chapter 5a ‘Approval of temporary attachment of movable property’ was added in Section II of the Act of 17 June 1966 on Enforcement Proceedings in Administration. Under these changes, from the beginning of 2022, movable property may be temporarily attached by an officer who conducts customs and tax inspection. Seized movable property may include, for example, machines, computers, raw materials and means of transport. An authority may temporarily seize movable property even before the end of the customs and tax inspection. The new regulations are aimed at increasing the efficiency of public debt collection. The change in the regulations resulted from the recognition of the existing legal regulations as defective, i.a. due to the difficulty in searching for the debtor’s assets. The aim of this paper is to assess the legislative correctness and operation of the construct of temporary attachment of movable property. The following problems have been identified: (1) whether the legislator has indicated the criteria for assessing if in a given situation temporary attachment will increase the efficiency of enforcement; (2) whether the legislator has included a definition of the term ‘efficiency’ in the discussed provision; (3) whether a tax and customs officer is obliged to temporarily attach movable property or whether it may not be seized despite the conditions being met; (4) whether the provisions establishing temporary attachment of movable property lay down rules for estimating the value of the seized movable property. A formal and dogmatic method has been used to carry out the above analysis. This method involves a linguistic and logical analysis of legal texts. In response to the questions posed, it has been established that the legislator did not indicate the criteria according to which it would be assessed whether in a given situation temporary attachment would increase the efficiency of enforcement. Nor did the legislator define the concept of ‘efficiency’. Interpretative doubts have also been raised as to whether the officer is obliged to temporarily seize movable property or whether it may not be attached despite the conditions being met. In addition, the provisions establishing temporary attachment of movable property do not lay down rules for estimating the movable property value.

Scientific reasoning is one of the important skills students and graduates need today. Scientific reasoning is part of high-level thinking skills and is one of the skills required in school curriculum implementation. Even though it is an important skill, research data shows that students' scientific reasoning is still unsatisfactory. The purpose of this study is to examine how junior high school students' scientific reasoning is affected when the 5E learning cycle model and multi-representation-based E-LKPD are used to execute learning. The study was carried out during the even semester of the 2022–2023 school year at SMP Negeri 2 Panti. Students in classes IX B and IX E served as the research samples, while all IX students comprised the study's population. The study used the quasi-experimental design method in conjunction with a quantitative methodology. Examinations, observations, interviews, and documentation were used to gather research data. Research data was analyzed by applying several tests, including the N-gain test, the normality test using Shapiro-Wilk, and the independent sample t-test. The research results show that implementing the 5E learning cycle model using multi-representation-based E-LKPD positively influences and impacts the scientific reasoning of students.
A Review on Its Characterization, Processing, Applications and Health Benefits of Pearl Millet Protein
Authors: Sagar Prashant
Published: May 2024

Millets have more minerals and vitamins. They have a greater potential to health benefit, fodder, nutrition, livelihood, fibre, and the environment than rice and wheat do. because Millet is a popular seed crop all over the world due to its high amount of micro and macro nutrients such as fibre, protein, vital fatty acids, vitamins and minerals. One of the most significant grains in the world and a significant food crop is pearl millet (Pennisetum glaucum L.). The UN recently declared 2023 as the "International Year of Millet." This review was written with the intention of giving a brief review of the studies on the characterization, preparation, applications, and health benefits of millet-based proteins because grains are the majority of people's main source of nutrition and protein is the 2nd most abundance macronutrient in millet, suggesting that these cereals may be acceptable substitutes for plant-based protein. This knowledge will be crucial in finding research holes that prevent millet proteins from reaching their full potential. Researchers and the food business can use this information further to comprehend the variety of millet proteins that can be used as ingredients in the creation of novel cuisines. In order to increase millet production in India, the study concluded that the right trends, characterization, processing, food applications and health benefits should be provided.
Ecofriendly Management of Giant African Snail (GAS) Achatina fulica (Bowdich)
Authors: Tiwari Farindra
Published: May 2024

The Giant African Snail (GAS) is a native of East Africa and. Presently the snail had infested over many areas and is becoming very difficult to control. This snail feeds on over 500 species of vegetation, and given that the Eastern Uttar Pradesh is self-sufficient in vegetable production, the burden of this pest can be a significant threat to Eastern Uttar Pradesh’s domestic food security. The GAS can be considered the only agricultural polyphagous herbivorous pest which is a threat to public health since it is a known vector of the rat lungworm which causes eosinophilic meningoencephalitis in humans. The study can provide insight into the preferences for selected parts within a plant which can be incorporated into the design for more target-specific crop protection approaches. Giant African snails are an invasive, and can cause extensive damage to important food crops and other agricultural and natural resources. They eat crops, reducing yields and making them unsuitable for sale. Some snails grow to 15 cm in length and 5- 8 cm wide, whereas others only grow to 6.5 cm in length. Commonly, the shells are light brown with darker brown and cream bands. The present review evaluated that the GAS is the second worst invasive alien species in the world.

We conducted a comparative study of the effect of mineral and organic fertilizers on the yield and quality of 5 medium-ripened domestic onion varieties in an annual crop on the alluvial meadow soil of the Moscow region. Laboratory and field experiments were carried out by the Department of Agriculture and Agrochemistry of the VNIIO branch of the FNCO in 2020–2022 on sufficiently cultivated medium-loamy alluvial meadow soils of the central part of the Moskvoretsky floodplain. In the experiment with the 5th varieties and the 3rd variants of the mineral fertilizer system, the commercial yield of onions was 53.0 t/ha, whereas with the use of an organic fertilizer system – 58.4 t/ha. Accordingly, the increase in yield relative to the control without fertilizers in the first case was equal to 106, in the second – 117%, marketability – 93 and 95%. It has been established that when determining the need of plants for nutrients during the growing season, it is preferable to use methods of leaf diagnostics. On average, for 5 varieties of onion, the yield increase, according to the results of plant diagnostics, turned out to be 13% more than in variants with NPK doses calculated according to soil diagnostics. Biochemical quality indicators for all onion varieties and all fertilizer variants did not differ statistically significantly from the control. The quality of onion products practically did not depend on the applied fertilizer systems. The organic fertilizer system provided the best supply of nutrients to onions in the phase of the beginning of bulb formation, which was crucial for obtaining the greatest yield in an annual crop. On average, for 3 variants of the organic system, the soil contained 2.34 mg/100 g of mineral nitrogen in the phase of the beginning of bulb formation, whereas with the use of the mineral system – 1.65 mg/100 g, or 42% less.
Changes in the cellulolytic activity and microbial respiration of soils of different types under conditions of contamination with heavy metals
Authors: Zolotareva O. A. , Plekhanov I. O.
Published: May 2024

It has been experimentally established that when soils are polluted with heavy metals, the boundary concentrations of metals above which signs of ecotoxicity are detected are different for the microbial community. Inhibition of respiration of the studied soils was observed at lower doses of Pb, Zn and Cd than enzymatic cellulase activity. Cd compounds and polyelement contamination conditions are the most toxic for microorganisms. Concentrations of heavy metals have been identified that can have a significant negative impact on the soil microbial community at different levels of contamination of sod-podzolic, gray forest, leached chernozem and chestnut soils. In descending order of resistance to TM, the studied soils can be arranged in the following row: leached chernozem (Luvic Chernozem) grey forest (Eutric Retisol (Ochric)) chestnut (Haplic Kastanozem) ≥ sod-podzolic (Eutric Albic Retisol (Ochric)).
Composition, age, and sedimentation environment of the ore-hosting Eravna series of the Udino-Vitim zone (Western Transbaikalia, Russia)

Published: May 2024

Data on the composition, age and formation conditions of the Ulzutui and Kydzhimit strata, which are combined as part of the Eravna Series of the Eravna Subzone of the Udino-Vitim Zone, are considered. The Eravna series, at least 2400 m thick, is composed of tephroturbidites with a significant amount of lavas and tuffs of felsic and intermediate compositions, with which tectonic-gravitational mixtites are spatially and genetically related. The features of the structure and composition of the Eravna series indicate the formation of sediments in an open deepening marine basin adjacent to the zone of active volcanism. For the first time, according to the Miospores, the time of formation of the Ulzutui sequence is limited to the Late Devonian – Early Carboniferous (Late Famennian – Early Tournaisian), the Kyjimite strata is limited to the Early Carboniferous (Visean) ages. At this time, the Kyjimit volcanic zone was formed. The suprasubduction nature of the zone is evidenced by the features of volcanites (predominance of acidic varieties, belonging of basalts to the tholeiitic, and dacites and rhyodacites to the calcareous-alkaline series, the presence of high-potassium rock varieties, their belonging to the K-Na type of alkalinity, very low MgO values, low and moderate TiO2 contents, high Al2O3 and K2O, enrichment of volcanogenic rocks in large-ionic lithophilic elements relatively to highly charged elements, minimum in Nb and negative values of εNd), their spatial association with monzonites (have suprasubduction features) and tephroturbidites, as well as metallogenic specialization (Cu and Zn) of the Eravna series. We believe that the ore-hosting strata for both pyrite-polymetallic Ulzutui and Ozernoe deposits is the Upper Devonian–Lower Carboniferous Eravna series.

Published: May 2024

The first results of U–Th–Pb isotope dating of detrital zircons (dZr, N = 130, n = 91) from the Middle Danian sandstones (63.9–65.3 Ma) of the Cretaceous–Eocene Novorossiysk–Anapa flysch, widely developed in the Sochi synclinorium (Southern slope of the Western Caucasus) are presented. The maximum dZr age is 2973 ± 12 Ma, the minimum dZr age is 318 ± 3 Ma; weighted average age of the 4 youngest dZr ~ 322 ± 7 Ma. There are no signs of the destruction products of the Jurassic magmatites involved in the structure of the Greater Caucasus and the Crimean Mountains into the sedimentary basin, in which the Novorossiysk-Anapa flysch was formed. A high degree of similarity between the provenance signals of the Danian sandstones from the Novorossiysk-Anapa flysch, some Paleogene-Neogene and Early Quaternary (Early Pleistocene) sandstones of the Western Caucasus and Western Cis-Caucasia, red-colored Upper Permian and Lower Triassic sandstones of the Moscow syneclise, as well as Late Quaternary alluvium of the lower reaches of the draining vast expanses of the Russian plate Don and Volga rivers has been revealed. On this basis, it was concluded that in the Middle Danian there were no eroded mountain structures of the Greater Caucasus and Crimea, and the main volume of detrital material composing the Novorossiysk-Anapa flysch was formed due to the recycling of Permian-Triassic and younger strata of the Russian Plate.
Paleozoic reef formation in the Pechora syneclise and the Caspian basin – a comparative analysis
Authors: Kuznetsov V. G. , Zhuravleva L. M.
Published: May 2024

In the two marginal depressions of the East European Platform, the Pechora syneclise and the Caspian depression, reef formations are widely represented, but the stratigraphic intervals of their development are far from equal. In the Pechora syneclise, reef formation began in the second half of the Llandoverian, reached its maximum in the Frasnian and was replaced by the development of reef hills in the Famennian. The structures are represented both as asymmetric reefs framing the shallow zones at their boundary with relatively deep paleobasins and in the form of single structures within the latter. The reefs of the next global maximums, the Late Visean-Serpukhovian and Lower Permian, are developed only marginally at the boundary with the Ural paleoocean and its relic, the Pre-Urals foreland basin.
In the Caspian basin, reefs of all three global maxima of development are present, and there are both asymmetric reef systems framing the shelf edges and symmetric intra-basin isolated structures.
Such difference is due to the different paleogeomorphological type of the basins. The Caspian basin was sharply differentiated in depth throughout the Middle and Late Paleozoic, which led to the formation of reefs rising above the bottom of these basins. In the Pechora syneclise, depth differentiation of the basins occurred only in the late Devonian. Generally weakly dissected shallow seas of the Visiean-Serpukhovian and early Permian did not provide conditions for the formation of powerful reefs protruding above the seafloor. The latter were formed only on the edge of the Ural paleoocean, and in the Permian ‒ on the edge of the Pre-Ural foreland basin.

The results of experimental studies of the possibility of using strain gauges under local pulsed thermal loading to evaluate the tension of the press connections of bearing rings with shafts are presented. Samples of press joints with tightness in the range from 38 to 118 microns were made. As a result of the study of the patterns of heat flow propagation in bearing rings and tension samples by contact method and means of thermal imaging, the possibility of separating deformations associated with the influence of temperature on the deformation measurement area and the temperature gradient in the heating area is shown. The methods of inspecting the press joint when exposed to a heater ring with a heat power capacity of 80 kJ and a temperature of 200°C and measuring the deformations of the ring and shaft by an opto-polarizing sensor with a base of 60 mm and a resolution of 2×10 — 7 relative deformations have been experimentally implemented. A correlation has been established between the time of reaching the maximum of local deformations of the shaft with the tightness of the press joints and the sign of deformations of the bearing ring with the tightness of the press fit, the gap between the ring and the shaft.

The behavior of the construction under the influence of external factors is determined by three key groups of parameters of the metal composition (chemical, structural and deformation). Obtaining information about these parameters directly on the construction will effectively solve the problem of assessing its actual technical condition. The problem of non-destructive evaluation of the chemical composition of a metal is solved using portable spectrometers. The MicroLab-Z2 diagnostic complex has been developed to evaluate the other two groups of parameters. It has two functional blocks. The surface preparation unit ensures that the surface of the construction site has a roughness, flatness and level of applied mechanical hardening corresponding to the laboratory preparation of metallographic grinds. The research unit is a platform on which a metallographic microscope and a portable microhardness tester are installed. It allows metallographic researches with magnification up to x1000, surface microindentation, measurement of microhardness values at load of 0—200 gs and optical study of the morphology of imprints in any spatial position. The reliability of the data obtained by the MicroLab-Z2 diagnostic complex has been confirmed during comparative tests with stationary equipment. With the help of the developed device, an assessment of the structure parameters, contamination of metal with non-metallic inclusions, assessment of the degree of hardening and embrittlement of metal, detection of aging processes can be performed. The use of the MicroLab-Z2 diagnostic complex for operational non-destructive evaluation of structural and deformation parameters of metal constructions will allow us to reach a qualitatively different level of efficiency in performing production and input control of manufactured products, assessing the maintainability of defects, planning repairs and other compensating measures, and industrial safety expertise.

Damage of the endothelium as a result of activation of the complement system is one of the causes of thrombotic complications in COVID-19. Factor C3 plays a key role in this process. The attachment of its proteolytic product C3b to the cells initiates the formation of the membrane attack complex C5b-9, which forms a pore in the plasma membrane and cell death. Here, we investigated how histamine, secreted in the body by leukocytes and mast cells, can affect the binding of C3b to human umbilical vein endothelial cells (HUVEC). To visualize it, FITS-conjugated antibodies against the C3c were used. These antibodies bind to intact C3 and to C3b but not to C3a. We have shown that when cultured HUVECs are incubated with human blood plasma, factor C3/C3b accumulates in the form of rounded and diffuse foci on the surface of the endothelial cell monolayer. Pre-activation of HUVEC by histamine increases the number of С3/C3b attachment sites. These data suggest that histamine may enhance endothelial damage during complement hyperactivation in COVID-19 and in endotheliopathies caused by other diseases.
