Different fuel electrodes for reversible solid oxide cells (r-SOC) are investigated with the aim of improving performance in both solid oxide electrolysis cell (SOEC) and solid oxide fuel cell (SOFC) modes, and durability in reversible operation mode. Electrodes based on gadolinium-doped ceria (GDC) as a mixed ionic electronic conductor, and lanthanum-doped strontium titanate (LST) as an electronic conductor are selected. The current-voltage characteristics of r-SOC single cells, and their cycling durability up to 1000 cycles are evaluated. LST-GDC co-impregnated with Ni and GDC prove to be highly durable in reversible operation, as a suitable fuel electrode material for r-SOCs. © The Electrochemical Society.

Solar energy among the renewable energy sources (RES) plays an important role in fulfilling any country's energy demands. When the sunlight irradiates the photovoltaic (PV) modules, part of the light energy is directly converted into electric energy. Another part is converted into heat energy, which increases the working temperature and affects the output performance characteristics of the PV module. This paper proposes a dynamic mathematical model of PV modules working on solar irradiance and ambient temperature by calculating the PV module model parameters under different environmental conditions. The dynamic model of the PV module is suggested to simulate PV modules' output characteristics (voltage and current) under any environmental conditions. By employing MATLAB/Simulink, a PV output characteristics program is compiled. The whole day output characteristics of PV strings of a real PV power station are tested and compared with simulation results. The results depict that the established model can effectively reflect PV modules' output characteristics in actual operation and can be used for dynamic simulation of PV power generation. © 2021 IEEE.

Drying has been an eco-friendly and cost-efficient method to reduce post-harvest losses of agricultural crops. In various countries, the technique has been widely utilized in the form of Solar Dryer Dome (SDD) buildings. Accurate indoor microclimate forecasting is very important to implement smart control systems in SDDs that can maintain the ideal conditions, as the availability of solar energy is limited only at daytimes and the temperature may drop significantly during nighttimes in remote areas. The microclimate variables that play an important role in maintaining ideal environmental conditions include temperature and relative humidity. © 2022, The Authors. All rights reserved.

Profenofos is a widely used organophophorous pesticide for several crops and is detected in drinking water sources. This study investigated the degradation of profenofos using vacuum ultraviolet (VUV) compared with ultraviolet (UV). The factors affecting the degradation performance including pH, profenofos concentration, bicarbonate, nitrate, nitrite, natural organic matter (NOM), and aeration were examined. Profenofos removal efficiencies were 84% and 52% by VUV and UV after 7 min of irradiation, respectively (Initial profenofos concentration of 2 mg/L). Degradation of profenofos by VUV were 3 times faster than UV. The degradation rates decreased with increasing initial profenofos concentration. Direct photolysis at 185 nm and OH • played major roles for profenofos removal by VUV. Aeration enhanced the profenofos degradation and mineralization by VUV but not UV. Bicarbonate inhibited the profenofos degradation while nitrate (≤50 mg-NO 3 - /L) acted as a photosensitizer enhancing profenofos degradation. NOM from groundwater and surface water sources also inhibited the profenofos removal by VUV as high as 39% compared to deionized water. However, NOM promoted the profenofos removal by UV because degradation by OH • formed via NOM photolysis became the main degradation mechanism. The result of profenofos degradation under isolated NOM fractions elucidated that hydrophobic fractions had less inhibition compared to hydrophilic fractions. Identified products suggested the pathway of profenofos photodegradation were the breaking of the O-P bond and reduction of Br. © 2022, The Authors. All rights reserved.

This present research examines the behavioral intentions of Filipinos to use online grocery applications during the novel COVID-19 pandemic. The study proposes an integration of the health belief model (HBM) and the Unified Theory of Acceptance and Use of Technology (UTAUT2) to identify the factors affecting the acceptance and usage of Filipinos of online grocery applications in terms of the impact of health risk for COVID-19. To accurately measure the factors and their relationship to behavioral intentions and usage behavior, a questionnaire was developed and distributed to 373 residents in the Philippines. Partial least squares structural equation modeling (PLS-SEM) was applied as an analytical method for this study. The results revealed that performance expectancy, perceived benefits, perceived severity, and cues to action significantly influenced the behavioral intentions and usage of online grocery apps during the COVID-19 pandemic. The study’s findings can be utilized as a theoretical framework for future researchers of consumer behavior;e-commerce developers;and grocery industry retailers, to enhance the innovation and services of online grocery applications. The results of this study may also be used and capitalized on by investors and managers to apply in strategizing when developing and marketing online grocery applications among con-sumers. Moreover, the framework of this study may be adopted and utilized by other online markets, even in different counties. Further theoretical and practical aspects are discussed in this paper. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

The Impact of Microbreaks with Simplified ID Stretches on Muscle Fatigue: Insights from EMG and MMG Frequency Analysis During Suture Ligation Training

引用

Current Problems in Surgery 2025年

作者： Masataka NAKABAYASHI Yuta TSUKADA Kazuhiro ENDO Mechanical Systems Engineering Course Department of Fundamental Engineering School of Engineering Utsunomiya University Utsunomiya Japan Graduate Program in Mechanical and Intelligent Engineering Graduate School of Regional Development and Creativity Utsunomiya University Utsunomiya Japan Medical Education & Training Core Center for Department of Advanced Medical Technology Department of Surgery Jichi Medical University Shimotsuke Japan

Background Prolonged surgical procedures contribute to musculoskeletal fatigue among surgeons, potentially shortening their career span. To address this issue, this study investigated the effects of microbreak (MB) interventions on muscle fatigue during suturing and tying training by analyzing electromyography (EMG) and mechanomyography (MMG) signals. Materials and Methods Twelve male engineering students (8 without MB, 4 with MB) participated in the study. Biosensors were attached to the upper trapezius (UT) and anterior deltoid (AD) to measure EMG and MMG signals during the training. The frequency range for EMG was set at 10–350 Hz, and for MMG at 1–250 Hz. Short-time Fourier transform (STFT) and continuous wavelet transform (CWT) analyses were conducted. Subjective fatigue assessments were also performed to complement these analytical results. Results The MB intervention limited the reduction in the mean power frequency (eMPF) of AD EMG to approximately 2.1%. CWT analysis of EMG and MMG revealed that, under the no-MB condition, low-frequency components (LF/TP) increased by approximately 7.3% and high-frequency components (HF/TP) decreased by approximately 5.8% ( p < 0.01). Subjective fatigue levels reported under the MB condition indicated reduced fatigue in the neck and shoulders compared to the no-MB condition, although an increase in lumbar fatigue was observed. Conclusions EMG and MMG analyses demonstrated that MB interventions effectively mitigated the progression of muscle fatigue, particularly alleviating fatigue in the neck and shoulders. These findings suggest that implementing MBs could be a promising approach to reducing musculoskeletal strain during prolonged surgical procedures.

The TA experiment uses fluorescence telescopes to observe cosmic ray air showers. The telescope camera uses PMTs as Pixels. The telescope's PMT pointing direction has an uncertainty of 0.1°, and more precise measurements of the telescope's optical properties are needed to more accurately reconstruct the cosmic ray air showers. We have developed the Opt-copter which is a light source mounted on a drone that can be flown within the telescope's field of view. Observational experiments with the Opt-copter have provided a more accurate analysis of the telescope viewing direction. In this study, we estimate the effect of this measurement of accurate telescope viewing direction on the reconstruction of cosmic ray air showers. © Copyright owned by the author(s) under the terms of the Creative Commons.

The disaster area is a constantly changing environment, which can make it challenging to distribute supplies effectively. The lack of accurate information about the required goods and potential bottlenecks in the distribution process can be detrimental. The success of a response network is dependent on collaboration, coordination, sovereignty, and equal distribution of relief resources. To facilitate these interactions and improve knowledge of supply chain operations, a reliable and dynamic logistic system is essential. This study proposes the integration of blockchain technology, the Internet of Things (IoT), and the Internet of Everything (IoE) into the disaster management structure. The proposed disaster response model aims to reduce response times and ensure the secure and timely distribution of goods. The hyper-connected disaster supply network is modeled through a concrete implementation on the Network Simulation (NS2) platform. The simulation results demonstrate that the proposed method yields significant improvements in several key performance metrics. Specifically, it achieved more than a 30% improvement in the successful migration of tasks, a 17% reduction in errors, a 15% reduction in delays, and a 9% reduction in energy consumption. © 2023

Extended COSMOS, COSMOS X, is a major upgrade of the air shower simulation tool COSMOS, which has been developed since 1970’s. To be compatible with the environment of the modern personal computers, COSMOS X can be compiled with gfortran and intel fortran helped by cmake. In addition to the earth’s atmosphere, particle tracking in the arbitrary spherical media with a common center is available with COSMOS X. This allows seamless simulations in air, water, ice, soil, concrete and also simulations in the atmosphere of stars and planets. For the design of new experiments and calculations of cosmic-ray interactions in the non-earth environments, COSMOS X opens wide possibilities. Basic functions and some interesting applications of COSMOS X are presented in the conference. © Copyright owned by the author(s) under the terms of the Creative Commons.
