The recuperator has the potential to enhance engine performance, reduce fuel consumption, and lower pollutant emissions, making it a promising technology for promoting environmental sustainability. This study investigates the impact of a Gyroid recuperator on the performance of a four-stroke internal combustion engine. Experimental analyses compared engine performance at various set points of rotational speeds before and after recuperator installation. The results validate the effectiveness of the Gyroid recuperator in recovering waste heat, thereby leading to improvements in fuel efficiency. The optimal performance, characterized by an 832.31 J/s increase in recovered combustion heat energy, was observed at 7000 RPM. Additionally, the Gyroid recuperator achieved a maximum overall heat transfer coefficient of 7.9215 W/m2 K at 8000 RPM. The performance of the Gyroid recuperator was further analyzed using the log mean temperature difference method, which yielded a peak value of 114.4 °C at 7000 RPM. The effectiveness-number of transfer units’ method was also employed to assess its effectiveness. These results show that the recuperator can efficiently transmit and recover heat under certain working circumstances. The analysis suggests higher heat energy losses at lower speeds than high speeds, indicating a more efficient energy conversion process at higher engine speeds. The possibilities of the Gyroid recuperator to improve engine performance and its suitability for internal combustion engines are highlighted in this study. This technology offers a promising solution for improving vehicle efficiency and promoting environmental sustainability.

A novel cross-receptive field fusion cascade network with adaptive mask update for transfer health state diagnosis of manipulators

Manipulators, particularly planar parallel manipulators, are widely employed in high-end precision equipment to conduct precise positioning and operation tasks due to their advantages of high stiffness, high precision, and high load. Moreover, they are also frequently exposed to changeable working circumstances, which significantly cause inconsistent health state data distribution. Although transfer learning can successfully offset the above distribution discrepancies, it remains unclear how to identify and quantify the source domain knowledge’s contribution to the transfer process. To overcome these challenges, a novel transfer health state diagnosis framework, named cross-receptive field fusion cascade network with adaptive mask update (CFFCN-AMU), is developed and employed for manipulators. Specifically, a unique cross-receptive field fusion cascade module (CFFCM), in which the receptive field self-evaluator and channel attention mechanism are jointly designed, is constructed initially to achieve adaptive extraction and fusion of cascaded features. Subsequently, in the target domain fine-tuning stage, an adaptive mask update (AMU) strategy is implemented to evaluate the contribution of source domain knowledge and selectively guide the parameter updating process. Finally, some mechanistic model-driven cross-working condition transfer scenarios are investigated. Multiple sets of excellent transfer diagnosis results fully illustrate the transferability and superiority of the constructed CFFCN-AMU model.

Organophosphate ester exposure in nail salons: Health implications for workers

Organophosphates esters (OPEs) have become a preferred alternative in nail polish as plasticizers due to health concerns over previously used additives like dibutyl phthalate. However, the true extent of nail technicians' exposure to OPEs is largely unknown. This study shows that nail salon workers are significant exposed to OPEs, with varied concentrations found in air, dust, masks, and urine. The total concentrations of 11 OPEs in ultrasonic personal air samplers (UPAS) ranged from 251 to 1007 ng/m³, and in air conditioner filter dust from 371 to 14473 ng/g. Triphenyl phosphate (TPHP) was the most abundant compound found in the nail polishes used in these salons. On average, the concentrations of TPHP and diphenyl phosphate (DPHP) in workers' urine after work were 5.2 and 1.8 times higher than those before work, respectively. Two nail salons that had the highest nail polish usage also had very high concentrations of TPHP in surgical masks, dust, and UPAS. TPHP concentrations in workers’ urine after work were 19 and 13 times those before work, respectively, in these two salons. Human internal exposure assessment showed that the average exposure dose of TPHP after work was 1.8 times higher than that before work. On average, use of masks reduced OPEs in urine by 77%. In conclusion, frequent mask replacement is highly recommended, especially in long working circumstances. Without regular replacement, masks may accumulate OPEs from the air, potentially becoming another source of human exposure to OPEs. Therefore, more attention should be paid to the occupational exposure of nail salon workers to OPEs, particularly considering that most practitioners in this industry are young women of reproductive age.

Paramedics’ experiences and observations: work-related emotions and well-being resources during the initial months of the COVID-19 pandemic—a qualitative study

BackgroundAs first responders, paramedics are an extremely important part of the care chain. COVID-19 significantly impacted their working circumstances. We examined, according to the experiences and observations of paramedics, (1) what kinds of emotions the Emergency Medical Service (EMS) personnel experienced in their new working circumstances, and (2) what work-related factors became resources for the well-being of EMS personnel during the initial months of the COVID-19 pandemic.MethodsThis qualitative study utilized reflective essay material written by experienced, advanced-level Finnish paramedics (n = 30). The essays used in this study were written during the fall of 2020 and reflected the period when Finland had declared a state of emergency (on 17.3.2020) and the Emergency Powers Act was implemented. The data was analyzed using an inductive thematic analysis.ResultsThe emotions experienced by the EMS personnel in their new working circumstances formed three themes: (1) New concerns arose that were constantly present; (2) Surviving without proper guidance; and (3) Rapidly approaching breaking point. Three themes were formed from work-related factors that were identified as resources for the well-being of the EMS personnel. These were: (1) A high level of organizational efficiency was achieved; (2) Adaptable EMS operations; and (3) Encouraging atmosphere.ConclusionsCrisis management practices should be more attentive to personnel needs, ensuring that managerial and psychological support is readily available in crisis situations. Preparedness that ensures effective organizational adaptation also supports personnel well-being during sudden changes in working circumstances.

EFL Teachers’ Motivation of Professional Development at the University Level in China

The motivation of instructors has been found to have a significant impact on students' enthusiasm to learn a second language, but less attention has been paid to the motivation of English Foreign Language (EFL) teachers, especially in the Chinese environment where English plays a significant role. In order to lay the groundwork for the formulation of suggestions on how to increase teacher motivation and consequently boost the standard of instruction and student performance, this study explores the motivation of English instructors at the university level in China. 203 native Chinese EFL instructors who are currently employed at institutions in China’s mainland participated in the study. The motivation of EFL instructors for selecting a profession in teaching and the elements influencing that motivation was investigated using a quantitative approach design. For the purpose of evaluating the level of English writing skills of EFL instructors, a survey with close-ended questions that was founded on theories of motivation and modified from earlier research was utilized as the instrument. Then proportion, frequency, mean, and statistic tests were used to analyze the survey data. The findings indicate that the EFL instructors had a variety of motivations for deciding to work as teachers, with intrinsic motivation being the primary driver, followed by altruistic motivations like wanting to support English education in their own countries. The findings also showed that a variety of factors, such as positive student feedback, personal happiness, and a solid wage, had an impact on the motivation of EFL teachers. Demotivating variables were discovered to be extrinsic, such as poor pay and few other sources of money, uncomfortable working circumstances, and students' unfavorable attitudes.

Railroad Catenary Insulator Fault Detection Based on Improved Faster R-CNN

Background:: The railroad catenary insulator, which is a crucial component of the catenary system and is situated between the pillar and wrist arm, is crucial for electrical conductor isolation, electrical equipment insulation, mechanical load bearing, anti-fouling, and anti-leakage. The catenary insulators will experience tarnished flash, breakage, insulation strength deterioration, and other issues as a result of the long-term outside unfavorable working circumstances. The train electrical system's ability to operate normally is greatly hampered by these problems. Although there are many patents and articles related to insulator fault detection, the precision is not high enough. Therefore, it is crucial to improve the precision of catenary insulator fault detection. Objective:: An improved region-based convolutional neural networks (Faster R-CNN)-based fault detection method for railway catenary insulators is proposed in response to the long detection time of the conventional railroad catenary insulator fault, the low precision of the catenary insulator fault detection for occlusion and truncation, the poor performance of multi-scale object detection, and the processing of class unbalance problem. Methods:: The Faster R-CNN is optimized from four perspectives: feature extraction, feature fusion, candidate box screening, and loss function, in accordance with the properties of the catenary insulator. First, to solve the problem of multi-scale catenary insulator fault detection, convolutional block attention module (CBAM) and feature pyramid network (FPN) are used to fuse the deep feature and shallow features of the image. This results in a feature map with more critical semantic information and higher resolution. After that, the weighted non-maximum suppression (WNMS) algorithm improved by distance-intersection over union (DIOU) and Gaussian weighting function is used instead of the traditional NMS algorithm, which effectively introduces the overlap of detection frames into the confidence level and makes full use of the effective information of the detection frames. Finally, the improved Focal loss is used as the classification loss, and the focusing parameter and the balance factor of the Focal Loss are adjusted dynamically to solve the problem of sample imbalance and difficult sample identification in the model better. Results:: The effects of SSD, YOLOV3, traditional Faster R-CNN and improved Faster R-CNN models are tested on the contact network insulator fault detection dataset constructed in this paper, and the experimental results show that the improved Faster R-CNN has higher precision, recall, and mAP compared to the other detection models, which reach 94.31%, 96.68% and 95.22%, respectively. Conclusion:: The results of the experiments demonstrate that this method may successfully detect the faults in different scale catenary insulators. It can effectively detect truncated, obscured faulty catenary insulators. It has higher precision and recall and provides a reliable reference for maintaining faulty insulators in railway catenary.

Enhanced Nitrate Nitrogen Removal from Constructed Wetland via Fe3O4/Granular Activated Carbon Anode Microbial Electrolysis Cell under Low C/N Ratio

In this study, a constructed wetland–Fe3O4/granular activated carbon anode microbial electrolysis cell (CW-FMEC) was constructed to enhance denitrification in low COD/N ratio wastewater. The introduction of Fe3O4 boosted the expression of functional genes involved in the denitrification pathway, and the abundance of narG, nirS, and nosZ increased by 99.29%, 70.54%, and 132.18%, respectively, compared to CW. In addition, the content of c-type cytochromes (c-Cyts) and EPS were also enhanced in the CW-FMEC. The microbial communities study displayed that Thauera, Dechloromonas, and Arenimonas became the main genera for denitrification. The denitrification performance at different COD/N ratios was investigated in depth. Under optimal working circumstances, the CW-FMEC had an excellent nitrate removal rate (88.9% ± 1.12%) while accumulating nearly no NO2−-N or NH4+-N in the effluent. This study provides a new direction for the development of CW-MEC and accelerates its implementation.

Sustainable Consumption and Social Justice: Should Countries Take Action to Ban the Sale of Products Made under Sweatshop Conditions?

This paper investigates the subject of sweatshop labour and the debate over whether countries should prohibit the sale of products produced under such conditions. The introduction emphasises the importance of better working conditions and minimal standards in sweatshop factories, while also admitting that customers may be ready to pay slightly higher costs to support better working circumstances for sweatshop workers. However, economists say that sweatshop labour is preferable than not working or working for extremely low wages, and that a blanket ban on sweatshop products could result in job losses and other negative repercussions. The literature study explores a range of viewpoints on sweatshop labour, including moral and financial grounds. Additionally, it highlights how consumer movements and market pressure influence businesses to improve working conditions. The paper also emphasises the issue's complexity and the need for a fair policy that considers employees' rights and practical factors. To improve the working circumstances of sweatshop workers, a multi-pronged strategy is recommended. This method includes consumer pressure, government regulation, and voluntary codes of conduct. The importance of striking a compromise that takes into account differing points of view and deals with the complexities of the sweatshop labour issue is emphasised in the conclusion. Overall, the study provides a thorough assessment of the subject, emphasising the necessity for ethical manufacturing processes and improved working conditions while taking into account economic ramifications and unexpected consequences.

A review of Li‐ion battery temperature control and a key future perspective on cutting‐edge cooling methods for electrical vehicle applications

AbstractCovid‐19 has given us a new way to look at our globe with regards to minimise air and noise pollution and thereby upgrading global environmental conditions. This positive pandemic outcome indicates that green energy is the future of energy, and one new origin of green energy is lithium‐ion batteries (LIBs). Electric vehicles are constructed with LIBs, but they have a number of disadvantages, including poor thermal performance, thermal runaway, fire dangers and a higher discharge rate in low‐ and high‐temperature conditions. The underlying fault of LIBs is their temperature reactivity. Extreme temperatures and challenging working circumstances can cause lithium‐ion cells to malfunction and cause the battery pack (BP) to overheat. For optimal performance in vehicles and long‐term LIB durability, LIBs must be thermally managed within their operating temperature span. This paper presents an overview of several cooling strategies used to maintain the internal BP temperature. This paper discusses cooling techniques using air, liquid and phase change material (PCM), heat pipe. Additionally, various BP configurations and heat generation techniques are explored. This research also discusses the usage of nanomaterials to address the BP's heat‐related problems. This study emphasises the use of nanomaterial to boost the heat conductivity of coolant in order to raise the batteries temperature into their ideal working range (PCM as well as liquid cooling). This article also provides some of the research gaps that have been found and the crucial areas on which attention should be directed in order to build the best lithium‐ion battery thermal management system technology.

Sustaining work ability amongst female professional workers with long COVID.

Long COVID (LC) compromises work ability (WA). Female worker WA has been more adversely impacted than WA in men. Exploration of lived experiences could elucidate the WA support required. To explore the working conditions and circumstances experienced as affecting sustained WA amongst female workers with LC, to help mitigate worklessness risks. Online semi-structured qualitative interviews were conducted with 10 female workers self-reporting or formally diagnosed with LC who had made some attempt to return to work (RTW). Interviews were analysed using template analysis to map themes informing WA enablers and obstacles onto a biopsychosocial model of rehabilitation. All participants were professionals working in an employed or self-employed capacity. Key themes reflecting circumstances that afforded sustained WA included the autonomy over where, when and how to work indicated as facilitated by a professional role, rapid health care access, predominantly sedentary work, competent colleagues able to cover for transient reduced WA, a strong interface between specialist health and management support, and accessible organizational policies that steer health management according to equity rather than equality. Highly flexible, iterative, co-produced RTW planning, tolerant of fluctuating symptom expression appears vital. In return for providing such flexibility, participants felt that employers' workforce diversity and competence would be protected and that workers would need to reciprocate flexibility. These qualitatively derived findings of workers' lived experiences add to existing guidance on supporting WA for people struggling with LC. Moreover, the same principles seem appropriate for tackling worklessness amongst working-age adults with complex long-term health conditions.

Natural zeolite supported g-C3N4/ZnO/Ag3PO4 composite: A tandem n-n heterojunction for simultaneous photodegradation of dyes under visible and solar irradiation

Various zinc-based ternary composite photocatalysts with variable weight percent ratios of g-C3N4:ZnO/Ag3PO4 in pristine and natural zeolite supportedform were prepared using precipitation and solid-state methods, respectively. X-ray diffraction (XRD), Brunauer, Emmett, and Teller (BET), Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDX), Thermogravimetric analysis (TGA/DTA), Fourier Transform Infrared (FTIR), Ultraviolet–Visible Diffuse Reflectance (UV–Vis DRS), and Photoluminescence (PL) techniques were used to investigate the as-produced composites. The photocatalytic efficacy of the developed materials was studied considering methyl orange dye (MeO) and laboratory-prepared mixed dyes as target pollutants. The photodegradation (MeO) performance of the natural zeolite-supported (NZGZA-1) ternary system was found to be 87.1% under optimal working circumstances. The primary active species engaged in MeO decolorization were the holes. The photodegradation efficiency under outdoor experiment yielded 98.2 and 78.9 %, for MeO and mixture of dyes respectively. After five consecutive cycles, the reusability of the supported catalyst was examined, and a 47.2 % decline was recorded at the end of the fifth cycle showing the fairly well stability of the catalyst. The photocatalytic degradation of the studied model pollutant follows pseudo-1st-order kinetics. The present work evidenced beneficial use of natural zeolite as support to ternary photocatalyst systems with enhanced efficiency apart from meeting the criteria for circular economy. Thus, reusing of spent natural zeolite as a support for composite photocatalysts could be considered viable alternative to disposing the same to the environment.

Thermal storage performance of latent heat thermal energy storage device with helical fin under realistic working conditions

Latent heat thermal energy storage has garnered increasing interest and development as a significant technique for recovering waste heat. In this research, the latent heat thermal energy storage device with helical fin is proposed and its thermal storage performance is also investigated by numerical simulation. First, assorted helix pitches (400 mm, 200 mm, 100 mm and 50 mm) and fin numbers are taken into account to investigate the thermal storage performance with various fin parameters. Then, four types of nanoparticles (SiC, TiO2, CuO and Al2O3) are dispersed into the phase change material to address the inherent defect of poor thermal conductivity of phase change material. Afterwards, several realistic working circumstances, including four inclination angles (θ = 0°, 30°, 60° and 90°) and eight oscillating inlet temperatures among which the frequencies are 1 Hz, 2.5 Hz, 5 Hz and 10 Hz, and amplitudes are 0.25, 0.5, 1 and 2, are selected to explore the impact on melting process. The results indicate that shortening helix pitch and increasing fin number can accelerate the melting rate, while the selection of these two parameters needs to consider the thermal storage performance and the processing difficulty as a whole. Furthermore, the selection of nano phase change materials needs to balance the relationship between thermal storage rate and capacity. Compared to the complete melting time when the device is placed vertically, the complete melting time is reduced by 14.3% when the device is placed horizontally. Utilizing the oscillating inlet temperature reduces the complete melting time by at least 21.2% compared to using the steady inlet temperature. When the frequency value is increased from 1 to 10, the complete melting time is only reduced by 3.4%. Complete melting time of the amplitude of 2 is 12.9% shorter than that of the amplitude of 0.25.

Seismic Response and Security Assessment of Cross-Fault Hydraulic-Tunnel Lining Structures

The foundation of a seismic safety assessment of cross-fault hydraulic tunnels is an acceptable and accurate seismic response. A dynamic contact force algorithm that may take into consideration the interaction between the fault–surrounding rock–lining structure was devised in light of the contact characteristics of various media in cross-fault hydraulic tunnels under seismic activity. A quantitative instability criterion using a relative displacement ratio as the criterion was devised based on the cusp catastrophe model. By using the cross-fault hydraulic tunnel of the Lawa Hydropower Station as an example, it was possible to evaluate and assess the impacts of four working circumstances on the seismic response of the tunnel lining structure. The findings demonstrated that the lining haunch exhibited stronger stress and displacement responses when subjected to seismic activity. The consideration of fault–surrounding rock–lining interaction exacerbated the displacement and stress seismic responses of the lining structure. The haunch, bottom arch, and top arch of the lining’s characteristic parts—which ranged in size from large to small—responded more seismically as peak ground acceleration rose. Applying the aforementioned instability criterion, the haunch, bottom arch, and top arch of the liner structure could withstand maximum peak ground accelerations of 0.10 g, 0.20 g, and 0.35 g, respectively. The aforementioned technique offers a fresh perspective on how to evaluate the seismic response and seismic safety of the tunnel’s lining structure, and the study’s findings can serve as a guide for seismic design.

Immobilized hindered amine radical scavenger for durability enhancement of perfluorosulfonic acid membrane in PEMFCs

Membrane durability is one of the crucial considerations that restrict the development of proton exchange membrane fuel cells (PEMFCs). The widely used and inexpensive stabilizer hindered amine 4-amino-2,2,6,6-tetramethylpiperidine (TEMP) was selected as the free radical scavenger and tethered onto the skeleton of carboxyl-functionalized metal-organic frameworks for addressing its migration problem. The resulted inorganic-organic hybrid dopant (UIO-66-TEMP) was then incorporated into the Nafion matrix to alleviate the attacks of free radicals on the membrane in the fuel cell working circumstances. Besides the improved mechanical strength and oxidative stability, and restricted water swelling and hydrogen crossover, the resulted hybrid membranes also possess excellent proton conductivity up to 176 mS cm−1, endowing them with high power density up to 612.78 mW cm−2, 1.5 times higher than recast Nafion. After accelerated durability testing for 120 h, the OCV decay rate of the hybrid membranes decreased to 0.74 mV h−1, only 40% of recast Nafion (1.89 mV h−1). Meanwhile, the optimized hybrid membrane still maintained a high peak power density of 463.62 mW cm−2 and a low hydrogen crossover density of 4.44 mA cm−2, which were superior to recast Nafion after OCV durability tests. Hindered amines can be “regenerated” by the “Denisov cycle” to ensure that they can be used sustainably in the fuel cell. The results demonstrate that the novel UIO-66-TEMP decorated with hindered amine radical scavengers are promising nanofillers for mitigating the membrane degradation and improving the proton conductivity, thereby significantly enhancing the performance and durability of PEMFCs.

Investigation of arranging doctor schedules during the COVID-19 outbreak by using a decision support system

People with minor symptoms are isolated at home, while those with severe symptoms are treated in hospitals. The hospital burden has so increased excessively. Healthcare workers experience physical tiredness as a result of stress. In addition to the growing workload, healthcare providers have psychological issues due to their worry of contracting an infection and spreading it to others. Healthcare personnel needs to be protected and given adequate working circumstances. Since protective gear including gloves that are secure, respiratory protection, and eyewear are crucial for the protection of medical professionals exposed to the virus, medical treatment should also be well arranged for. The fast-spreading COVID-19 epidemic has impacted numerous individuals throughout the globe. Considering the strong infectivity, governments issue advisories to stay at home or enact policies like lockdowns to prevent the spread of the illness. Arranging doctor scheduling is one of the crucial difficulties. As part of this study, create a doctor scheduling arrangements with a hospital in Turkey during the COVID-19 epidemic. In order to sustain activity in the new departments while lightening the load in the old departments, the hospital built three new COVID-19-related departments. To solve the arranging doctor scheduling issue, provide a Mixed Integer Programming (MIP) paradigm to turn the problem into a Decision Support System (DSS). The consequential schedules maintain healthcare delivery throughout all departments while distributing their effort evenly by reducing the risk of the doctors contracting the illness.

Personality moderators of the cross-sectional relationship between job demands and both burnout and work engagement in judges: The boosting effects of conscientiousness and introversion

The central question of this study is whether buffering, boosting and exacerbating effects of the Big Five personality factors extraversion, openness to experience, agreeableness, conscientiousness and neuroticism can be demonstrated in the relationship between two job demands (i.e., work pressure and working overtime) and both burnout and work engagement in 257 Dutch judges. It is important to better understand the interaction effects between various job demands (work pressure and working overtime) and personality on both burnout and work engagement in judges given their increased risk of burnout and lower work engagement due to cognitively and their emotionally demanding work. Three hypotheses were tested in a cross-sectional design study. Moderation analyses showed that, as expected, conscientiousness significantly boosted the relationship between working overtime and work engagement. Hence, high scorers on conscientiousness showed more work engagement when working overtime. Also, extraversion moderated the relation between working overtime and work engagement, but only at a low level of extraversion. Thus, contrary to expectations, introverts showed more work engagement when they work overtime. Also, significant main effects were found. Work pressure and neuroticism related positively to burnout, while extraversion and agreeableness related negatively to burnout. Moreover, extraversion, agreeableness and conscientiousness related positively to work engagement. In our study, conscientiousness, extraversion and agreeableness can be considered as personal resources for judges, in line with the Conservation of Resources (COR) theory. Especially conscientiousness can facilitate judges to cope with challenging working circumstances and introversion ensures that judges stay engaged despite working overtime.
