Authors: Huang Xiang , Liang Zhihong , Zhang Qiankun , Mo Jianfeng , Zhao Lei
Published: March 2024

In order to realize the efficient storage of electric power job site data and ensure the utilization effect of the stored data, a method of electric power job site edge cloud data storage based on the Paxos algorithm is proposed. In this method, power field operation data are collected comprehensively through the edge server and edge controller in the edge computing module, the collected data are processed, and the data storage tasks are allocated reasonably. The allocated data are transferred to the data storage module, which identifies the bad data in the data through a gap statistics algorithm and cluster analysis and retains the valid and normal data. After the primary and secondary nodes are determined based on the Paxos algorithm, the data storage model of power operation site is constructed. After the consistency detection of the reserved data, the data storage of power operation site is completed. The platform management module can analyze the stored data and present the analysis results to the application decision-making module for presentation. The test results show that the maximum time delay and energy consumption are 2.15 s and 42.6 W, respectively, when the method is used for data transmission, which can accurately identify the bad data in the field data of electric power operation, and the reliability index results of data consistency detection are all above 0.95, which ensures the good consistency of the stored power operation site data and effectively completes the power operation site data storage.
Four-Dimensional XStrain Echocardiographic Assessment of Left Ventricular Strain and Rotational Mechanics: Technology, Clinical Applications, Advantages and Limitations
Authors: Mehrotra Akhil , Mehrotra Anurag , Shaban Mohammed , Kacker Shubham
Published: March 2024

Because of its excellent ability to non-invasively assess left ventricular (LV) systolic function, two-dimensional speckle tracking echocardiography (STE) is increasingly being used in echocardiographic laboratories worldwide. Two-dimensional STE is the most sought-after method to evaluate LV strain, rotation, twist and torsion. Two dimensional, three-dimensional and four-dimensional (4D) deformation estimation by STE has several intrinsic limitations. For better appraisal of LV contractile properties, a recently introduced updated version of 4D XStrain STE has been used to analyse the various complex multidimensional LV mechanics. This novel technology is a reliable, economical and simple tool for estimating regional and global myocardial function. Furthermore, 4D XStrain STE can accurately quantify the 4D LV ejection-fraction, LV volume and sphericity index. However, this technology has not been extensively implemented, and its assessment remains limited primarily to research applications. Hence, we aim to promote this innovative technology by comprehensively addressing its technique, advantages and limitations, so that it can be better applied in cardiovascular disease.

Authors: O Khalifa Mohamed , A Ahmed Ossama , Safwat Eslam
Published: March 2024

Background/purpose: Prognostic value of serum alpha-fetoprotein (AFP) in hepatocellular carcinoma (HCC) is still debatable. We aimed to study this role in HCC patients who underwent radiofrequency ablation (RFA). Methods: Records from HCC patients were retrospectively analyzed between January 2011 and December 2015. A minimum data set for each patient record of a follow-up period of at least 1 year was pre-defined before enrollment. In all, 153 patients were enrolled. AFP levels were recorded for all patients at the time of diagnosis, 1 month after RFA and at 3-month intervals afterward. Patients were divided according to pretreatment AFP level into 3 groups: group 1: AFP <20ng/mL, group 2: AFP 20-200ng/mL and group 3: AFP >200ng/mL. Results: Pretreatment AFP is not significantly correlated with age, baseline lesion number or size, baseline Child score or class, post RFA recurrence or death. The overall survival rates were 95%, 75.6%, 55.6%, 48.8%, and 48.8% at 1, 2, 3, 4, and 5years respectively. On comparing the 3 groups on disease-free survival, there was no statistically significant difference among the three classes. Child class A patients showed statistically significant better survival after RFA than those with Child class B. The ROC curve showed that AFP had inadequate accuracy to discriminate survivors and deceased patients and to discriminate patients with recurrence from those without recurrence.

Published: March 2024

Background: Depression is very prevalent and a comorbidity in musculoskeletal pain. Physical therapists treat high volumes of patients with musculoskeletal pain, thus warranting a need to screen patients for depression for safety and proper treatment. The aim of this study was to screen patients attending outpatient physical therapy for depression and determine what variables predict the presence of depression. Patients and methods: A convenience sample of patients attending outpatient physical therapy for musculoskeletal pain was asked to complete a survey consisting of demographic information and the Patient Health Questionnairre-9 (PHQ-9), nine-item depression scale. Results: The patient sample consisted of 320 patients with a mean age of 52.36 (±78) years with a mean duration of pain of 5.89 (±6.69) months. Mean PHQ-9 score at intake was 5.37±4.84) with 14.1% of the patients classified as moderate to severe depression. The variables most associated with a high PHQ-9 score were being disabled (β = 4.26, p = 0.01), having personal injury insurance (β = 4.04, p = 0.12) and a high body-mass index (β = 3.75, p = 0.30). Lower PHQ-9 scores were associated with getting more sleep (β = -0.76, p = 0.02) and higher minutes of exercise per week (β = -0.004, p = 0.25). Conclusions: Approximately one in seven patients attending outpatient PT for musculoskeletal pain present with moderate to severe depression. Various patient characteristics were identified that may indicate a higher likelihood of clinical depression, which may aid in the identification of depression in patients with musculoskeletal pain. Additional research is needed to validate these preliminary findings from this study.

Wybrane aspekty zjawiska dyskryminacji i wykluczenia społecznego na przykładzie mniejszości niemieckiej w Rzeczypospolitej Polskiej
Authors: Biernacka Magdalena
Published: March 2024

Zjawisko dyskryminacji i wykluczenia społecznego mniejszości niemieckiej w Polsce było widoczne zwłaszcza w okresie powojennym i w czasach komunizmu. Mniejszość niemiecka doświadczyła ze strony władz licznych form dyskryminacji, które wynikały z napięć politycznych i narodowościowych. Pomimo postępującej integracji społeczności niemieckiej nadal istnieją wyzwania związane z nieścisłościami prawno-instytucjonalnymi, które mogą prowadzić do sytuacji dyskryminacyjnych w sferze publicznej czy zawodowej. Dlatego ochrona praw mniejszości narodowych i etnicznych w Polsce jest kluczowym aspektem w procesie budowania społeczeństwa wolnego od dyskryminacji i wykluczenia społecznego.

Authors: Kowalczyk Aneta
Published: March 2024

Konsekwencją przeniesienia miejsca świadczenia pracy poza siedzibę pracodawcy, w miejsce wskazane przez pracownika, jest konieczność dostosowania regulacji prawnych, jak również określenie w nich standardów dotyczących warunków zatrudnienia w nowej rzeczywistości pracowniczej, którą stanowi praca zdalna. Regulacje Kodeksu pracy określają w związku z tym w sposób ogólny zasady świadczenia pracy zdalnej, ale środek ciężkości został przeniesiony na ustalenia stron lub partnerów społecznych. W tym ostatnim przypadku mamy do czynienia z porozumieniami określającymi zasady wykonywania pracy zdalnej, których stroną są partnerzy społeczni, czyli związek lub związki zawodowe i pracodawca. Pojawia się w związku z tym pytanie o charakter prawny tych porozumień, w szczególności czy można je zaliczyć do źródeł prawa pracy. W artykule dokonano analizy przesłanek ustawowych koniecznych do tego, aby dane porozumienie można było uznać za źródło prawa pracy. Wnioski wyciągnięte na tej podstawie pozwoliły udzielić odpowiedzi na pytanie postawione na wstępie.

The solution to the problem of developing an oxidation-stable dressing with high nutritional value based on unrefined first cold-pressed linseed, corn and sesame oils is considered. The objects of the study are the following indicators: antioxidant, fatty acid composition, induction period of accelerated oxidation of oils, blends and finished products. The rational range of oilratios in the blend, enriched with a-linolenic acid, stabilized against oxidative spoilage due to natural antioxidants – tocopherols, sesamol, sesamolin, is substantiated. The ratio of linseed, corn and sesame oils is 1:2:1, respectively. The characteristics of the blend are as follows: the ratio of ω-3:ω-6 fatty acids is 1:1.7; the induction period of accelerated oxidation (at 80 °C) – 4.1 h. A model sample of the dressing was produced using the developed blend. It was proven that the sample of the dressing of the proposed composition retains its organoleptic and physico-chemical parameters (titratable acidity, dry matter content, acid and peroxide values of the oil fraction) during 30 days of storage at a temperature of 8±1 °C. A feature of the obtained results is the possibility of increasing the nutritional value of the dressing based on unrefined oils while preserving the extended shelf life of products. From a practical point of view, the development of such products allows expanding the range of competitive dressings with high nutritional value. An applied aspect of using the obtained scientific result is the possibility of modeling the composition of dressings or other oil products based on valuable oil raw materials, depending on the ratios of the oil base components of the product

Published: March 2024

The object of research is a Stadier-type apparatus for analytical electrophoresis of proteins. In the milk proteins research, in addition, there is a need to carry out serial express analyzes of their various groups, as well as the isolation of individual homogeneous fractions. The dimensions of working chambers for analytical, express, and micro preparative electrophoresis of caseins and milk whey proteins were proposed to solve this task. For each type of electrophoresis, different chambers and formers are used without changing the design of the apparatus. The apparatus is suitable for electrophoretic systems used for the analysis of milk proteins. Analysis of casein in the anodic system of a homogeneous polyacrylamide gel in the presence of urea allows identification of the main fractions: αS1-CN-8P, αS1-CN-9P, αS2-CN-10P, αS2-CN-11P, αS2-CN-12P, αS2-CN-13P, β-CN-5P, ϰ-CN-1P and three β-casein fragments f(29-209), f(106-209) and f(108-209). Express electrophoresis in the presence of urea reveals four fractions of caseins: αS1-CN, αS2-CN, β-CN, and ϰ-CN. The analysis of whey proteins in the Davis native disc electrophoresis system allows identification of β-Lg A, β-Lg B, α-La, BSA fractions, and a group of immunoglobulin fractions. The express electrophoregram differs by a common band A and B variants of β-Lg. Due to an adequate selection of electrophoretic systems, it is possible to identify semi-quantitatively all the main fractions of milk proteins under analytical or express mode. The adapted apparatus also makes it possible to conduct micro preparative electrophoresis and obtain the main fractions of milk proteins. In this case, the yield of electrophoretically pure proteins is: β-CN-5P (23±5 %), β-Lg (A+B) (27±6 %), α-La (11±3 %), and purified groups of αS1-CN-8P+αS1-CN-9P (25±6 %), αS2-CN-(10-13P) (6±1.5 %) and ϰ-CN-1P (7±2 %). The apparatus could be used at enterprises producing dairy protein products
Development of a new fast drying determinant method using resistivity for the industry of coconut shell charcoal briquettes
Authors: Prasetyadi Andreas , Sambada Rusdi , Purwadi Petrus Kanisius
Published: March 2024

The charcoal briquette industry faces the problem of the method for determining the drying stop during its production. The combustion method as the main method is time-consuming. The test needs 3 hours to get the result. In order to find a new fast method for drying determinant, the resistivity method was proposed for rainbow coconut shell charcoal briquettes. The briquettes had a length of 3.8 cm, height of 2.2 cm, and width of 2 cm with a half-tubular top side. 50 samples of each three drying conditions (wet, half-dry, and dry) of the same drying batch were collected. These conditions were determined by a drying expert of a coconut shell charcoal briquette company. Then, the resistances were measured and the geometrical factor was applied to find their resistivities. A model of resistivity in the cross-sectional layer was also applied to find the coefficients of front-tail, base-top, and side-side directions. These coefficients became a special way to find the position of the wet part in half-dry briquettes. The results of the work show that resistivities in combination with their distribution can potentially be used for fast drying stop determinant. The wet and dry briquettes have a resistivity difference order of 102. The resistivities of the wet and dry briquettes are 450 kiloohms and 28 megaohms for every centimeter of length, respectively. The half-dry and dry briquettes have the same order of resistivities. However, the resistivity distribution of both conditions is very different. The dry briquettes have homogenous resistivities among the measurements emphasizing the drying process of the solid. It was also found that the half-dry briquette has a surface dry part until 0.55 cm depth. The center of the briquette is still wet

The object of the study is the territory that became the object of the influence of hostilities. The study is dedicated to finding ways to assess the state of ecosystems and ensure their stability in the conditions of military conflicts.
The impact of military conflict on the environment is highlighted through the analysis of risks and losses in ecosystems.
It has been studied that the intensity of armed conflicts determines the scale and degree of damage to ecosystems, and the use of destructive weapons leads to the direct destruction of natural environments and their components.
It has been determined by an expert survey that the most significant changes in natural ecosystems are the biodiversity losses, deforestation, territorial changes and the destruction of natural objects (scores ≥9.0). Factors of low impact (score <6.75) are air pollution, erosion due to air pollution, biodiversity losses due to water pollution.
The interrelationships between military actions and environmental pollution are studied for the importance of understanding these processes for effective management of environmental security during military conflicts.
A mathematical and graphic model of material flows has been developed, which allows taking into account resource flows, pollution and losses in the ecosystem during armed conflicts.
The model, tested in the Kyiv region, made it possible to determine the priorities of conservation and risk management. Analysis of 9,000 km2 revealed contaminated areas, in particular, in the southwestern and western directions.
The practical use of the research results is in the development of strategies for minimizing and restoring the ecological consequences of armed conflicts. This can help improve the management of natural resources in the context of military operations and increase the resilience of ecosystems
Accelerating the process of text data corpora generation by the deterministic method
Authors: Yusyn Yakiv , Zabolotnia Tetiana
Published: March 2024

The object of research is the process of generating text data corpora using the CorDeGen method. The problem solved in this study is the insufficient efficiency of generating corpora of text data by the CorDeGen method according to the speed criterion.
Based on the analysis of the abstract CorDeGen method – the steps it consists of, the algorithm that implements it – the possibilities of its parallelization have been determined. As a result, two new modified methods of the base CorDeGen method were developed: “naive” parallel and parallel. These methods differ from each other in whether they preserve the order of terms in the generated texts compared to the texts generated by the base method (“naive” parallel does not preserve, parallel does). Using the .NET platform and the C# programming language, the software implementation of both proposed methods was performed in this work; a property-based testing methodology was used to validate both implementations.
The results of efficiency testing showed that for corpora of sufficiently large sizes, the use of parallel CorDeGen methods speeds up the generation time by 2 times, compared to the base method. The acceleration effect is explained precisely by the parallelization of the process of generating the next term – its creation, calculation of the number of occurrences of texts, and recording – which takes most of the time in the base method. This means that if it is necessary to generate sufficiently large corpora in a limited time, in practice it is reasonable to use the developed parallel methods of CorDeGen instead of the base one. The choice of a particular parallel method (naive or conventional) for a practical application depends on whether or not the ability to predict the order of terms in the generated texts is important
Development of a wind turbine with two multidirectional wind wheels
Authors: Issenov Sultanbek , Antipov Pyotr , Koshumbayev Marat , Issabekov Dauren
Published: March 2024

The object of research is a wind generator with counter-rotating blades. A special feature of this design is the presence of two wind wheels that rotate in opposite directions. Wind wheels are on the same axis, between them there is a certain distance, which is determined based on research data. The problem of modern wind power is the low range of operating wind speeds, weak generation at low wind speeds. The upper speed limit is 25 m/s, exceeding which leads to breakdowns of various units of the wind station, especially this affects the integrity of the blades, rupture of the wind wheel, cracking of the metal parts of the bearings and their fasteners. The wind turbine presented in the article allows to achieve an increase in the generation of electric energy by 50–70 %. This is achieved by increasing the relative rotational speed of the rotor relative to the stator. Therefore, even at low speeds, the rotor speed relative to the stator increases, which leads to an increase in power generation. The design of the device includes: two wind wheels, one transmits its rotation to the stator, the second to the rotor axis, a metal base, a current collector mechanism. For conducting the research, an experimental model and a semi-industrial installation were used. Results studies have confirmed the theoretical increase in the generation of electrical energy by this design. The peculiarity of the obtained results is connected with the determination of the distance between two wind wheels, the optimal distance between them corresponds to the maximum energy generation. A distinctive feature of the results obtained can be considered an increase in the number of blades on the second wind wheel
Making Dementia Matter Through Sound
Authors: Gysels Marjolein , Tonelli Chris , Johannsen Thomas
Published: March 2024

This paper investigates the working practices of the Genetic Choir and the “Stem&Luister” project, in which the ensemble uses voice, sound and improvisation to explore and develop ways of connecting with people with dementia, thereby seeking to improve the experience of care. Their musical sessions are multilayered. First, through listening they develop a sense of the people and the environment. Then through introducing their vocal practices, they breach the prevailing sonic regime. Second, through immersing the residents in sound-making and singing, they draw on the material and sensorial qualities of sound. This gives access to those who were difficult to reach and offers both an alternative means of communication and enables the recognition of selves. A third layer concerns the strategic use of improvisation, of which the deployment of “ensemble” and “instant composition” are analysed. Recognising the compositional efforts in improvisation shows their work to be a form of design. It facilitates attention to personhood, relations, and diversity. This specific practice appears as an untapped resource for the health and wellbeing of people with cognitive and speech impairments. Theoretically, the findings have implications for the notion of care and provide support from practice to existing neurological evidence of the significance of music as a fundamental faculty for survival and wellbeing.
Evolutionary Approaches to Religion and the Problem of Transcendent Meaning
Authors: Becker Patrick
Published: March 2024

This article analyzes the concept of religion within the framework of evolutionary biology. It critiques a reductionist view that understands religion primarily in terms of function and the grounding of such an interpretation in principles of chance. Common understandings of the role of chance do not derive from biological evidence; a broader understanding of this element is needed. Likewise, limiting religion to its evolutionarily ascertainable benefits overlooks the fact that these benefits only materialize when there is belief in the transcendent purpose that religion provides. Consequently, the article advocates for the recognition of religion as an emergent cultural phenomenon whose essence can never be fully captured through a purely functional, scientific lens.

Climate change poses significant threats to ecosystems, human health, and global stability. Despite international efforts to reduce greenhouse gas emissions, the Earth’s climate continues to warm, leading to extreme weather events, rising sea levels, and other detrimental impacts. In response to this crisis, scientists have begun exploring various strategies to mitigate climate change through geoengineering, which involves deliberate interventions in the Earth’s climate system. This article provides an overview of climate geoengineering research, focusing on key techniques, challenges, and ethical considerations, including actions being taken by the American Geophysical Union (AGU), a nonprofit professional scientific society, to develop an ethical framework to help guide research in this important area. AGU also is driving global engagement on this topic, including with leaders and members of faith communities.

High safety requirements are imposed on the operation of production facilities. One of the requirements is periodic diagnostics of equipment and structures. Technical diagnostics is the recognition of the state of a technical system, which includes a wide rangeof problems associated with obtaining and evaluating diagnostic information. Surveys provide extensive information about the diagnostic object, which allows us to conclude about the operability of the object, to make a decision about repairs or modernization.The article discusses the process of diagnostics, its shortcomings and methods of their elimination. A program for automating the process and processing the results of technical diagnostics is proposed. The implementation of the development is aimed at increasing the reliability of the data obtained, reducing labor costs, and improving the state of safety at production facilities. It is also assumed that when using the development, the number of industrial accidents that occurred due to human factor errors during technical diagnostics will be reduced.The program consists of four elements, which will allow them to be gradually implemented in production: a sensor-server commu-nication system, a database, an electronic technological scheme of the object, a computing module. The communication system will simplify the transmission of data from the control sites. The database will facilitate work with documentation for control objects. The information available on the electronic technological scheme will increase the speed of interaction of employees of various services during diagnostics. The calculation module will eliminate the human factor during calculations and accelerate the formation of control acts and the conclusion of the industrial safety expertise.The joint use of all elements of the program will facilitate and accelerate the work on technical diagnostics and simplify the work with documentation for research objects.

Published: March 2024

This protocol details our workflow for performing concentration and total nucleic acid extraction from wastewater primary sludge (settled solids) for the purposes of untargeted RNA and DNA sequencing of viruses present in wastewater. Protocol overview: In this protocol, 20 mL of wastewater sludge is concentrated to a final volume of 400 uL using the InnovaPrep Concentrating Pipette Select. Prior to concentration, the wastewater sample is treated with Tween 20 and sonicated to dissociate viral particles from solids in the wastewater matrix. The sample is then centrifuged to remove larger solids. The pellet is discarded, and the supernatant is filtered with a 0.45 um PES 75 mm filtration unit to remove remaining suspended solids and bacteria. This filtrate is then concentrated with the Concentrating Pipette, using Ultra CPT tips and recommended device settings for the InnovaPrep modified wastewater processing protocol. Nucleic acids are then extracted from the concentrated product using the Zymo quick-DNA/RNA Viral kit using the manufacturer protocol with a few modifications that we have found to be helpful.

Renovation, refurbishment, restoration, and retrofitting of existing structures have grown more challenging issues for the construction profession. Construction buildings are susceptible to damage at the time of the earthquake and need strengthening to enhance their strength, stiffness, and ductility. Fabric-reinforced cementitious matrix (FRCM) techniques have been recently introduced to the construction sector as a feasible solution for fiber-reinforced polymers (FRP) in strengthening application. FRCM composed of high strength fabric grids with cement-based material serve as a binder for FRCM matrices. The binder employed for FRCM composed of cement-based mortar along with polymers are added to improve the bond strength properties. The cementitious matrix utilized in FRCM has superior thermal resistance and better compatibility with the concrete surface. The utilization of FRCM matrix for upgrading and restoring the concrete members is gaining more prominence as a replacement to FRP. This work conducts a thorough analysis of the application of FRCM techniques to concrete structural members like beams, columns, slabs, and beam-column joints. This paper primarily aims to present the FRCM process on structural members and to discuss the flexural, shear, and load carrying FRCM materials that are used in the field.

BBR test is commonly used to assess the low-temperature performance grade (PG) of asphalt binders, with the flexural-creep stiffness being a critical parameter calculated through this test. However, it has notable limitations that demand attention. The significant amount of asphalt binder needed for test specimens increases costs and resource consumption. Additionally, the complex and time-consuming specimen preparation process hinders testing efficiency and introduces result variability, affecting the accuracy and reliability of PG determinations. In recent years, machine learning (ML) has emerged as a promising substitute for predicting various engineering values. In this study, the primary focus was on harnessing super learner (SL) techniques to predict the creep stiffness of asphalt binders. The SL approach combines multiple ML algorithms to enhance predictive accuracy and reduce individual model biases. Bagging, boosting, and stacking algorithms were employed in the construction of these prediction models. To conduct the investigation, data from 1350 samples sourced from the Long-Term Pavement Performance (LTPP) website were utilized to explore the influence of six crucial variables on the creep stiffness of asphalt binders. The proposed method demonstrated high accuracy, nearing 90% in the coefficient of determination. The Stacking model achieved a low Mean Absolute Percentage Error of 2.86% and robust Prediction Accuracy of 97.14% for randomly selected data points. Furthermore, the sensitivity analysis highlighted the significance of distinct input variables in influencing the creep stiffness of asphalt binders. Notably, the test temperature emerged as the most influential factor affecting creep stiffness, according to the conducted study

Published: March 2024

Research on Proton Exchange Membrane fuel cells is an important area in the field of modern energy sources. Such fuel cells are characterized by high efficiency and fast response times, making them a promising solution for sustainable energy production. Fuel cells operate under both static and dynamic conditions. Such varying operating conditions result in achieving different efficiency of fuel cell systems. This study attempts an experimental and modeled efficiency evaluation of a 1.2 kW open-cathode air-cooled fuel cell stack under static and dynamic conditions. A Sankey energy balance and an analysis of the balance components were determined for the fuel cell stack operating in these two operating states. Simultaneous modeling of the fuel cell under both static and dynamic conditions was carried out. The efficiency values of the fuel cell stack were found to be slightly higher under static conditions than under dynamic conditions. Modeling fuel cells in static and dynamic conditions results in slightly different parameters (better conformance was obtained for static models).
