Published: August 2024

Renal replacement therapy (RRT), widely used in the treatment of renal injury in the course of sepsis, aims to eliminate the toxins and proinflammatory cytokines, involved in the pathomechanism underlying septic shock. Dialysis filters characterised by a high adsorption potential for cytokines in RRT when septic renal injury is the case. It is of key importance in the antibiotics treatment of sepsis to achieve desired values of PK/PD indices. Continuous renal replacement therapy (CRRT) may affect antimicrobial clearance, increasing their elimination in some cases. The aim of this study was to determine the degree of adsorption for linezolid, on three different types of filters used in CRRT. In our in vitro study a continuous veno-venous hemofiltration (CVVH) was conducted using 3 types of filters: polysulfone (PS), polyethyleneimine-treated polyacrylonitrile (PAN PEI) and non-PEI-treated polyacrylonitrile (PAN) filters. Each type of filter was used in 3 CVVH cycles, involving the use of 600 mg of linezolid dissolved in 700 ml of bovine blood or in 700 ml of 0.9% NaCl. In each case the total volume of the obtained solution was 1000 ml. Blood samples, at particular time points, were collected in order to measure drug concentration. The differences in mean drug/NaCl adsorption and drug/ blood adsorption were determined using one-way ANOVA with multiple comparisons by Tukey post-hoc test. A p-value of < 0.05 was considered to be significant. A significant adsorption of linezolid was found for PAN PEI filter, both in samples obtained from bovine blood and 0.9% NaCl solutions, at the endpoint. No significant adsorption was demonstrated on PAN or PS filters. There is a need for in vivo research to confirm the effect of filter type on linezolid concentration in patients undergoing CRRT.

Authors: Kim Juneseok , Hong Ilyoung
Published: August 2024

Traditional terrain analysis has relied on Digital Topographic Maps produced by national agencies and Digital Elevation Model (DEM) created using Airborne LiDAR. However, these methods have significant drawbacks, including the difficulty in acquiring data at the desired time and precision, as well as high costs. Recently, advancements and miniaturization in LiDAR technology have enabled its integration with Unmanned Aerial Vehicle (UAV), allowing for the collection of highly precise terrain data. This approach combines the advantages of conventional UAV photogrammetry with the flexibility of obtaining data at specific times and locations, facilitating a wider range of studies. Despite these advancements, the application of UAV LiDAR in terrain analysis remains underexplored. This study aims to assess the utility of UAV LiDAR for terrain analysis by focusing on the doline features within karst landscapes. In this study, we analyzed doline terrain using three types of data: 1:5000 scale digital topographic maps provided by the National Geographic Information Institute (NGII) of Korea, Digital Surface Models (DSM) obtained through UAV photogrammetry, and DEM) acquired via UAV LiDAR surveys. The analysis results indicated that UAV LiDAR provided the most precise three-dimensional spatial information for the entire study site, yielding the most detailed analysis outcomes. These findings suggest that UAV LiDAR can be utilized to represent terrain features with greater precision in the future which is expected to be highly useful not only for generating contours but also for conducting more detailed topographic analyses, such as calculating area and slope of the study sites.

Authors: Aichele Stephen R.
Published: August 2024

Anxiety in older adults is a prevalent yet under-recognized condition associated with significant societal and individual burdens. This study used a machine learning approach to compare the relative importance of 57 risk and protective factors for anxiety symptoms in a population-representative sample of middle-aged and older European adults (N = 65,684; ages 45–103 years; 55.7% women; 15 countries represented). Results revealed loneliness and self-rated poor health as primary risk factors (Nagelkerke R2 = .272), with additional predictive contributions from country of residence, functional limitations, financial distress, and family care burden. Notably, follow-up analysis showed that none of 16 social network variables were associated with loneliness; rather, cohabitating with a partner/spouse was most strongly associated with reduced loneliness. Further research is needed to elucidate directional associations between loneliness and anxiety (both general and sub-types). These findings underscore the imperative of addressing loneliness for mitigating anxiety and related mental health conditions among aging populations.

Authors: Okui Nobunori
Published: August 2024

Real driving emissions (RDE) test procedures for type approval were initiated in Japan in 2022. In Japan, the test vehicle is driven on a test road (test course) by tracing the speed pattern prepared for each RDE test. The vehicle needs to trace the patterns in the same manner as in the conventional chassis dynamometer test. The use of a driving robot is effective for reproducibility in precisely tracing the target vehicle speed during these tests. In this study, we developed a driving robot for electrified vehicles (HEV, plug-in HEV, BEV, and FCV), which have regenerative brake-control systems. We applied a new logic to our robot that was developed in-house for conventional engine vehicles. We focused on braking deceleration of the regenerative brake control to change the operation timing from the accelerator pedal to the brake pedal. We verified the improvement of speed traceability of the driving robot installed with the proposed logic on the chassis dynamometer and test road.

Published: August 2024

Model-based development (MBD), which utilizes system models to design complex products, has received increasing attention. However, an advanced control system design scheme is required to accurately control the developed products under harsh conditions for practical usage. This paper proposes a control system that integrates a data-driven compensator (DDC) with a model-based control (MBC) system design. The proposed method considers a hierarchical control structure comprising an upstream control system based on the MBC design approach and a downstream control system that includes a plant control loop with a DDC. The proposed system can always maintain the desired performance by driving the MBC based on an ideal model because the downstream control system, DDC, maintains the characteristics of the ideal model even if the plant properties change owing to changes in operational and/or environmental conditions. In this study, the design scheme for unifying models and data in the MBD process is called smart MBD (S-MBD), and the proposed control system design scheme is based on the S-MBD approach. The effectiveness of the proposed hierarchical control system is verified by applying it to a hydraulic excavator.
Buoyancy and Propulsion Mechanisms for Stable Movement in Snow Field
Authors: Fujiuchi Haruka , Sumita Shinichirou , Mikami Sadayoshi
Published: August 2024

For small-sized mobile machines, moving on snow without sinking is challenging. Snowmobiles are often used to move on snow. However, in smaller-sized machines, the skis attached to the machine become small, so small snow bumps or soft powdered snow quickly cause the entire machine to be buried under the snow. Therefore, it is necessary for small robots moving on snow to give appropriate driving mechanisms for producing propulsive force and snow-floating force. To this end, we propose new driving mechanisms, a “passive wing wheel” and a “spiral screw,” for small mobility services that move on snow without sinking or getting stuck. The passive wing wheel has transformable wing-like paddles, which extend to behave like animal feet and shrink to form a wheel if necessary. The spiral screw is designed to produce propulsive force by pushing snow particles with the screw. Additionally, by combining two sets of screws having opposite threads, they gather snow underneath the body attached to them, which causes floating force. This report also proposes ways to prepare pseudo-snow, which resembles natural snow in hardness, viscosity, and property transformation due to deformation. We conducted experiments to measure the performance of the proposed design in both the pseudo-snow and natural snow. From experiments, we confirmed that the mechanism performs well in terms of propulsion and floating on snow.

The article discusses the topic of mutual trade between prosumers at the same level. By increasing the amount of electricity distributed in the grid, it becomes possible to reduce the flow of electrical power in the grid, which in turn helps to reduce power losses and reduce voltage. This opens up an opportunity for prosumers to become participants in the Energy Market, and for ordinary consumers to receive electricity at prices that are lower than the basic tariffs set by energy supply companies. The article pays attention to the analysis of electricity trade between prosumers and ordinary consumers, as well as the role of distributed system operators in this process. The concept of peer-to-peer trading and the system model are described. The influence of different types of prosumers, their economic incentives and sanctions for violation of the rules is studied. The prosumer model is discussed in detail, including loads, renewable energy sources, battery system for energy storage, and switching equipment. It is noted that the purpose of market regulation is to solve a centralized problem that can be solved by a central operator with access to consumers' private information. The proposed method uses a low-voltage flexibility market in which consumers are connected to a single feeder. They form a community of prosumers among themselves and participate in the flexibility market. Limiting consumers to the level of low-voltage networks reduces flexibility, but allows to increase the efficiency of calculations. In addition, prosumers at the connection point can compete with each other to provide aggregate flexibility at low voltage levels. ORG provides the necessary flexibility of the peer-to-peer market in view of voltage limitations and congestion of distribution networks.

Published: August 2024

The quantitative and qualitative parameters of the frequency regulation of the electric drive of the pumping units of the centralized heat supply network were determined. The necessity and possibility of using the frequency-regulated electric drive of pumping units in the networks of centralized heat supply, in the mode of their operation of quantitative and qualitative regulation of the coolant supply, is well-founded. The frequency control parameters were calculated on the basis of technical data related to the operating mode, where the flow rate of the coolant changes according to the hydraulic load typical for HVAC applications defined by the European Union Regulation, as well as the technical data of the pump, frequency converter and electric motors provided by the manufacturers. The definition of parameters concerns the operation of pumping units in a typical operating cycle characteristic of district heating networks, which involves operation with a reduced load for a long time. The results were obtained that correspond to the range of the speed of rotation of the electric drive, its power, torque, coolant supply and hydraulic pressure of the pump in a real typical network of centralized heat supply. The practical significance of the obtained results is that they can be used for the modernization of the electric drive of pumping units of the centralized heat supply network, which until now are operated with non-regulated electric drives based on an asynchronous motor with a short-circuited rotor and throttle regulation of the coolant supply.

Published: August 2024

To ensure the functioning of radio electronic equipment (RAE), semiconductor power converters (NPEs) are used, which perform the functions of converting and adjusting the parameters of electrical energy. The modern consumer needs NPEs with a rigid set of operational characteristics - ensuring functional parameters in a wide range of changes in all disturbing factors. The existing principles of NPE construction do not always allow such a set of characteristics to be realized. The article analyzes the stability of the pulse voltage stabilizer based on high-frequency magnetic amplifiers, taking into account the technological spread of their core parameters. The circuit of the voltage stabilizer is presented, its operation is described, the principle of operation of the high-frequency magnetic amplifier is disclosed, and its transfer function in the frequency domain is found. The study is based on the use of interval analysis theory. The conducted analysis of the stability of the NPE, taking into account the interval uncertainty of the parameters of the cores of high-frequency magnetic amplifiers, confirmed their performance both with technological dispersion of the parameters of the cores and with a wide range of changes in all disturbing factors, including the parallel operation of voltage stabilizers on a common load.

Published: August 2024

The energy market is inherently quite sensitive to crises, particularly those that directly affect society. In particular, this declaration is related to companies engaged in the supply of electricity to individuals and small or medium-sized enterprises. The current consequences of the pandemic and the amplification of military confrontations around the world show that fundamental transformation processes, both purely technical and economic, are currently underway. For example, in Ukraine, it is necessary to rebuild external economic ties, protect against infrastructure destruction and take into account the ability of customers to pay for services on time. In order for companies involved in certain processes to respond rapidly to the challenges of today, it was decided to develop a model for forecasting market volumes under non-deterministic conditions, based on vector autoprogression algorithms and neural networks. The following methods are used: analytical and inductive methods for forming factors of external influence and description of target companies; expert evaluation method for determining the most influential external indicators; experimental method, statistical methods of processing time series and methods of multi-criteria evaluation to determine the most effective autoregression model. In the outlined circumstances, the most important component of the proposed approaches is the phase of data preprocessing, which allows to take into account the external influences that characterize both social changes and general changes in the industry. In the course of the research, it was found that this influence can be divided into two components - the behavior profiles of the target audience and the market structure. The first indicator includes the transformation text descriptions of customers and average energy costs, while the second includes the state of the world economy, monopoly and investment contributions, corporate financial stability and energy prices. In addition to the above, each profile contains adjustments to social changes. Experiments conducted demonstrated the relative effectiveness of the proposed approach to data preprocessing in combination with convolutionary neural networks and vector autoregression of moving averages. This allows authors to the of its use in practice with the possibility of further using more complex algorithms.

Published: August 2024

The article analyzes the options for implementing renewable energy systems and energy storage on railway infrastructure and rolling stock. It is noted that the energy sector of the railway infrastructure of Ukraine, as well as some European countries, is not diversified by energy sources, and the use of renewable energy sources (RES) is limited. The possibility of using hybrid systems with photovoltaic batteries and a wind generator to meet the electricity needs of the railway infrastructure facility is considered. The concept of a regulated railway crossing operating on renewable energy sources (RES) in combination with electric vehicles (electric bicycle and electric tire) is proposed, which will ensure the balancing of the hybrid power supply system, storage of excess RES energy and generation of additional energy as needed. In accordance with the proposed concept, possible scenarios for the functioning of the railway crossing load were identified. The electricity consumption is estimated and a typical load schedule for a railway crossing is determined.

High Pressure Gas Lift Optimization Using Nodal Analysis
Authors: Abdelkerim O. , Leggett S. , Lu J. , Nelle W.
Published: August 2024

This study seeks to explore the potential benefits of high pressure gas lift (HPGL) optimization. We will compare HPGL optimization with constant injection rates evaluating the potential uplift in oil production and profitability across diverse well and reservoir conditions.

The methodology integrates nodal analysis simulation with economic analysis to optimize HPGL rates in tubing and annular flow. Initially, the study employs Prosper to create a baseline model representing average well and reservoir conditions in the Permian Basin. Subsequently, it simulates diverse well conditions (e.g., production rates, tubular configurations) and reservoir characteristics (e.g., pressure, productivity index), aiming to identify the most profitable gas injection rate considering varying oil prices and gas injection costs. Extensive sensitivity analyses further explore how all these various factors influence HPGL optimization, ensuring a comprehensive understanding of its efficiency and profitability.

This comprehensive study has shown significant results and insights. The implementation of HPGL rates significantly enhanced oil production and profitability compared to traditional constant gas injection rates. The study revealed that the gas injection rate that optimizes oil production does not always align with the gas injection rate that maximizes profits. The most economically efficient gas injection rate was identified by addressing the additional revenue from the incremental oil output against the costs associated with gas injection. Sensitivity analysis further highlighted the significant influence of various well and reservoir conditions on the efficiency of HPGL. This underlines the complexity of HPGL optimization, which demands a balance between technical feasibility and economic practicality. Additionally, the research uncovered that specific tubular configuration led to higher oil production and profitability when employing HPGL in unconventional wells and producing oil through the annulus, compared to the conventional method of producing oil through the tubing. This study suggests great potential for innovative approaches in HPGL strategies, offering promising avenues for enhancing oil recovery and financial returns in the petroleum industry.

This study intends to serve as a roadmap for HPGL operators to evaluate the incremental oil production and profits achievable in various well and reservoir conditions. Additionally, it introduces a direct method for single-point HPGL operators to estimate bottom hole pressure from measured surface injection pressure, surpassing the accuracy of traditional multiphase fluid correlations, which often rely on uncertain well tests and flow parameters, thus offering a more reliable approach for HPGL operations.
High-Pressure Gas Lift (HPGL) as an Alternative to Electric Submersible Pumps (ESP) in Wolfcamp Unconventional Wells. An Operational, Economic, and Production Performance Comparison

Published: August 2024

Determining artificial lift options in mid to late-life unconventional wells is paramount to the economic success of hydrocarbon recovery. This paper will compare two different artificial lift methodologies (HPGL & ESP) in wells in the same formations. Key comparisons of economics (CAPEX/OPEX), operational limitation, and ultimate hydrocarbon recovery between the two lift methodologies will be presented.

HPGL is known for its’ operational advantages such as its high tolerance for solids production, high gas-liquid ratios (GLR), and its’ overall versatility. Two wells targeting the same Wolfcamp A zone were converted from conventional gas lift to HPGL and ESP. This project's objective was to test HPGL's performance and economic viability in order to be utilized for future workover operations in the area. A year's worth of production, economic, and operational data will be presented in this paper.

In the first nine months after the initial lift installation, the well at which the ESP was installed suffered two ESP failures due to production solids causing equipment damage. The average run-life of each ESP was approximately 50 days. During the same time, Well #2 (on HPGL) continued producing with no downtime and minimal decline when compared to initial IP rates. After 9 months of production operations, the HPGL well outperformed the ESP well in terms of cumulative production. More importantly, the capital and operating cost per BOE produced between the two artificial lift systems was substantially lower in the HPGL well. Similar issues occurred in a third well (Well #3 Wolfcamp B formation) in the field. This time the ESP was replaced with HPGL- achieving better production performance compared to the ESP.

The operational simplicity and lower capital/operating costs of the HPGL system proved that it can be a competitive alternative to ESPs and Conventional Gas Lift in unconventional wells (Wolfcamp A & B formations). Considering that HPGL can be installed at the early production life and be the lift system of choice for early to late life of a well makes it an attractive option for production sustainability of wells that traditionally experience high decline rates and downhole equipment failures.

Published: August 2024

The sophistication of cyberattacks has significantly increased, making it almost certain that organizations can be victims of cyberattacks at any time. Managing cybersecurity risk is critical for any organization so that informed decisions can be made to tackle risks before they materialize. Cybersecurity risk management is context-specific and heavily relies on the specific organization’s context. However, performing effective risk management is always challenging due to the constant changes in organizational infrastructure and security posture, including the adoption of new applications and the reconfiguration or updating of existing assets and their dependencies, as well as the potential exploitation of vulnerabilities. Despite the wider adoption of AI enabled cybersecurity risk management, there is a lack of focus on the integration of these systems along with the dynamic elements of the risk management. In this context, this research proposes a novel dynamic Cyber Security Risk Management (d-CSRM)) framework to tackle this challenge by integrating dynamic parameters such as vulnerability exploitation and assets dependencies for assessing and managing the risk. The framework consists of a systemic process and makes use of a hybrid AI-enabled model that combines both linear regression and deep learning, to prioritize the vulnerabilities. Additionally, d-CSRM integrates the explainability and interpretability characteristics of the AI model for explaining model decision making and the inner working parameters. This allows the extraction of the key features that are linked with the risk and informed decision making to tackle the risks. An experiment was performed to prioritize the vulnerabilities from the widely used CVEjoin dataset using the proposed hybrid model to quantify the dynamic risk with explainability. The results show that the hybrid model effectively identifies and prioritizes the most critical vulnerabilities using the selected key features such as exploit type, exploit platform and impact that can further enhance the dynamic risk assessment.

Der Beitrag stellt die Beschwerdemöglichkeit des Bundes im Opferhilferecht vor. Er behandelt die Frage, wann das Eidgenössische Justiz- und Polizeidepartement (EJPD) zur Behördenbeschwerde gegen kantonale Entscheide betreffend Opferhilfe berechtigt ist und welche Funktion dabei dem Bundesamt für Justiz (BJ) zukommt. Er nennt jüngere Anwendungsbeispiele und erläutert, weshalb das BJ im Namen des EJPD auch Behördenbeschwerden «pro Adressat» führen kann und was Anwältinnen und Anwälte angesichts der Behördenbeschwerde beachten sollten.

L'article examine la possibilité pour la Confédération d'exercer un recours dans le cadre du droit de l'aide aux victimes. Il aborde la question de savoir à quel moment le Département fédéral de justice et police (DFJP) est en droit de contester les décisions cantonales relatives à l'aide aux victimes et décrit le rôle de l'Office fédéral de la justice (OFJ) dans ce contexte. L'article cite des exemples récents pour illustrer cette pratique et explique pourquoi l'OFJ peut également déposer des recours administratifs au nom du DFJP en tant que tiers agissant en faveur du destinataire de la décision contestée. Il souligne également les points auxquels les avocats doivent prêter attention lorsqu'ils traitent des recours administratifs.
Urban Sufism: The Dynamic of Cosmopolitan Religious Community
Authors: Jaenuri Jaenuri
Published: August 2024

The phenomenon of urban Sufism represents the new form of Sufism in the modern era. However, the diversity in urban society shows the dynamic of Sufism. This article is a qualitative study based on a library investigation that applies the Sufistic approach. Data collection was carried out by examining sources related to urban Sufism. This article found that internal and external factors influence the formation of religiosity in urban society. By nature, human beings need spirituality to seek their essence. In contrast, the external factors are discourses of modernisation and globalisation which are increasingly strengthened by some factors such as self-alienation, spiritual dryness, loss of humanism, hedonism, and materialism. The type of religiosity needed by modern urban society is universal, humane, social, logical, inclusive, and based on love and the principle of freedom.Contribution: This study contributes to providing a new horizon of religious reconstruction, especially for urban communities that need a more open and inclusive model of religiosity.
Arıtma Çamuru ve Bor Uygulamalarının Fasulyedeki (Phaseolus vulgaris L.) Ağır Metal ve Mikro Element Düzeyleri Üzerine Etkisi

Bu çalışma, artan dozlarda bor ve arıtma çamuru uygulamalarının fasulye (Phaseolus vulgaris L.) bitkisinde ağır metal ve mikro element içeriğindeki değişimlerinin belirlenmesi amacıyla yapılmıştır. İklim odasında tam şansa bağlı tesadüf parselleri deneme desenine göre hazırlanan araştırma, 3 tekerrürlü olacak şekilde yürütülmüştür. Standart bodur fasulye çeşidi olan Mina’nın kullanıldığı araştırmada, dört farklı bor dozu (B0:0mg/kg, B10:10mg/kg, B20:20mg/kg, B40:40mg/kg) ve dört farklı arıtma çamuru dozu (AÇ0:%0, AÇ5:%5, AÇ10:%10, AÇ20:%20) deneme faktörleri olarak kullanılmıştır.
Araştırmada atık çamuru uygulamalarının kontrole kıyasla fasulyedeki mikro elementlerden alüminyum (Al), bakır (Cu), mangan (Mn) ve çinko (Zn), demir (Fe), krom (Cr), kurşun (Pb), nikel (Ni), arsenik (As), kadmiyum (Cd) ve kolbalt (Co) gibi elementlerin içeriğini arttırmada etkili olduğu bulunmuştur. Aynı zamanda bor içeriğinde de azalmaya neden olduğu gözlenmiştir. En yüksek mikro element ve ağır metal içerikleri %5 ve %10 arıtma çamuru uygulamalarında ölçülmüştür. Diğer taraftan bor uygulamalarının fasulye bitkisindeki alüminyum, bakır, bor, çinko, kobalt, mangan ve nikel içeriğini kontrol bitkilerine kıyasla yükselttiği, demir, arsenik, kadmiyum ve kurşun içeriklerini ise düşürdüğü tespit edilmiştir.
Çalışma, arıtma çamuru uygulamaları sonucu artan metal içeriklerinin olumsuz etkilerinin bor uygulamalarıyla tolere edebileceğini göstermiştir. Bu tür bor uygulamalarıyla bitkilerde ağır metal kirliliğinin azaltılmasının mümkün olabileceği görülmektedir.
Relations between science and theology in interpretation of Dumitru Stăniloae
Authors:   Saints Cyril and Methodius Institute for Postgraduate Studies, Gridneva Maria V. ,   HSE University
Published: August 2024

The article explores Dumitru Stăniloae’s interest in natural sciences. The characteristic of his epistemology is given, which shows that he distinguishes three stages of knowledge of God: rational (affirmative and negative), apophatic and cognition based on specific life situations. The theologian’s increased interest in the rational stage of cognition, which makes possible and necessary strict science, is underlined as well as the interconnectedness of all stages, which determines the benefit of scientific knowledge throughout the path of human’s ascent to God. D. Stăniloae’s wide application of the rational method of cognition is illustrated by the example of his article “Church as a place and a large community in Christ”. In the course of studying D. Stăniloae’s works, the fact is highlighted that the Romanian theologian identifies a large number of interrelations, such as soul-body, human-world, creation-God, based on his Trinitarian theology and Christology. The substantiation of the importance of scientific knowledge is given due to the fact that it helps to strengthen and clarify the connection between cosmos-man-Christ-Trinity. The methodological features of cognition of the surrounding world in the context of the connection of scientific knowledge and knowledge of God are listed, and D. Stăniloae’s positive view of technological progress is also noted and characterized. At the end of the research, it is concluded that the Romanian theologian considers science to be a part of the knowledge of God and a means of natural Revelation, as well as the importance of combining scientific knowledge with apophatic knowledge of creation, which is possible as a consequence of the presence of God in the world.
