文摘Due to the endocrine toxicity,neurotoxic,and reproductive toxicity to organisms,the sources and risks of brominated organic pollutants have attracted widespread attention.However,knowledge gaps remain in the bromination processes of emerging phenolic pollutants in plants,whichmay increase the potential health risk associated with food exposure.Our study discovered that light induced generation and accumulation of more toxic brominated organic compounds(Br-org)in lettuce leaves under the stress of acetaminophen(ACE)than that without light,as evidenced by an increase in C-Br bond intensity in FTIR analysis.This result can be explained by the oxidation of bromide ions(Br^(-))by reactive species(ROS and ^(3)Chl*)of chloroplast into reactive bromine species(RBS).The main mechanism is that the redox of Br^(-)reduced the oxidative damage of ACE to the structure and function of chloroplasts,providing good conditions for light energy uptake and utilization and promoting the increase of pigments and active species.Compared with the dark group exposed to 5 mg/L Br^(-),the pigment content,H_(2)O_(2) and ^(1)O_(2) level of the light group increased by 56%,84% and 69%,respectively.On the other hand,RBS attacks certain electrophilic organic compounds in leaves to generate Br^(-)org.Triple excited state of chlorophyll(^(3)Chl^(*))was the dominant species for the transformation of ACE,while RBS is a key factor in the generation of Br-org in the Br^(-)/light/chlorophyll system.A total of six transformation products were identified by HPLC-MS/MS,which were involved in three transformation pathways:methylation,hydroxyl oxidation and hydroxylation followed by bromination.This is the first report that Br^(-)could enter the chloroplast and improved chloroplast structure under ACE stress,and elucidated the bromination mechanism of organics in terrestrial plant involving of biophotochemical bromination in chloroplast besides enzyme-catalyzed bromination.This study is beneficial for risk assessment and prevention of emerging phenolic pollutants.

文摘Shotcrete is one of the common solutions for shallow sliding.It works by forming a protective layer with high strength and cementing the loose soil particles on the slope surface to prevent shallow sliding.However,the solidification time of conventional cement paste is long when shotcrete is used to treat cohesionless soil landslide.The idea of reinforcing slope with polyurethane solidified soil(i.e.,mixture of polyurethane and sand)was proposed.Model tests and finite element analysis were carried out to study the effectiveness of the proposed new method on the emergency treatment of cohesionless soil landslide.Surcharge loading on the crest of the slope was applied step by step until landslide was triggered so as to test and compare the stability and bearing capacity of slope models with different conditions.The simulated slope displacements were relatively close to the measured results,and the simulated slope deformation characteristics were in good agreement with the observed phenomena,which verifies the accuracy of the numerical method.Under the condition of surcharge loading on the crest of the slope,the unreinforced slope slid when the surcharge loading exceeded 30 k Pa,which presented a failure mode of local instability and collapse at the shallow layer of slope top.The reinforced slope remained stable even when the surcharge loading reached 48 k Pa.The displacement of the reinforced slope was reduced by more than 95%.Overall,this study verifies the effectiveness of polyurethane in the emergency treatment of cohesionless soil landslide and should have broad application prospects in the field of geological disasters concerning the safety of people's live.
文摘Emergency department nurses face severe occupational stress leading to anxiety,depression,and burnout,which significantly impair their well-being and patientcare quality.This narrative review examined the role of mindfulness-based stress reduction(MBSR)in addressing these challenges.Rooted in nonjudgmental present-moment awareness,MBSR enhances emotional regulation and reduces psychological distress by fostering adaptive coping strategies.Studies have demonstrated its efficacy in lowering anxiety,depressive symptoms,and emotional exhaustion,while improving workplace well-being,empathy,and job satisfaction.Mechanistically,MBSR improves interoceptive awareness and autonomic balance,as evidenced by physiological markers such as heart rate variability.However,gaps remain in long-term efficacy assessments,personalized interventions,and integration with multidisciplinary approaches.Future research should prioritize tailored biomarker-driven programs,longitudinal studies,and scalable implementation strategies in high-stress clinical settings.This review underscores MBSR’s potential as a sustainable,evidence-based tool to enhance emergency department nurses’mental health and professional performance,advocating for broader adoption and further refinement of its practical applications.

文摘Typhoons can cause large-area blackouts or partial outages of distribution networks.We define a partial outage state in the distribution network as a gray state and propose a gray-start strategy and two-stage distribution network emergency recovery framework.A phase-space reconstruction and stacked integrated model for predicting wind and photovoltaic generation during typhoon disasters is proposed in the first stage.This provides guidance for second-stage post-disaster emergency recovery scheduling.The emergency recovery scheduling model is established in the second stage,and this model is supported by a thermal power-generating unit,mobile emergency generators,and distributed generators.Distributed generation includes wind power generation,photovoltaics,fuel cells,etc.Simultaneously,we con-sider the gray-start based on the pumped storage unit to be an important first step in the emergency recovery strategy.This model is val-idated on the improved IEEE 33 node system,which utilizes data from the 2022 super typhoon“Muifa”in Zhoushan,Zhejiang,China.Simulations indicate the superiority of a gray start with a pumped storage unit and the proposed emergency recovery strategy.

文摘Electrical energy is essential for modern society to sustain economic growths.The soaring demand for the electrical energy,together with an awareness of the environmental impact of fossil fuels,has been driving a shift towards the utilization of solar energy.However,traditional solar energy solutions often require extensive spaces for a panel installation,limiting their practicality in a dense urban environment.To overcome the spatial constraint,researchers have developed transparent photovoltaics(TPV),enabling windows and facades in vehicles and buildings to generate electric energy.Current TPV advancements are focused on improving both transparency and power output to rival commercially available silicon solar panels.In this review,we first briefly introduce wavelength-and non-wavelengthselective strategies to achieve transparency.Figures of merit and theoretical limits of TPVs are discussed to comprehensively understand the status of current TPV technology.Then we highlight recent progress in different types of TPVs,with a particular focus on solution-processed thin-film photovoltaics(PVs),including colloidal quantum dot PVs,metal halide perovskite PVs and organic PVs.The applications of TPVs are also reviewed,with emphasis on agrivoltaics,smart windows and facades.Finally,current challenges and future opportunities in TPV research are pointed out.
文摘BACKGROUND Monkeypox(Mpox),is a disease of global public health concern,as it does not affect only countries in western and central Africa.AIM To assess Burundi healthcare workers(HCWs)s’level of knowledge and confidence in the diagnosis and management of Mpox.METHODS We conducted a cross-sectional study via an online survey designed mainly from the World Health Organization course distributed among Burundi HCWs from June-July 2023.The questionnaire comprises 8 socioprofessional-related questions,22 questions about Mpox disease knowledge,and 3 questions to assess confidence in Mpox diagnosis and management.The data were analyzed via SPSS software version 25.0.A P value<0.05 was considered to indicate statistical significance.RESULTS The study sample comprised 471 HCWs who were mainly medical doctors(63.9%)and nurses(30.1%).None of the 22 questions concerning Mpox knowledge had at least 50%correct responses.A very low number of HCWs(17.4%)knew that Mpox has a vaccine.The confidence level to diagnose(21.20%),treat(18.00%)or prevent(23.30%)Mpox was low among HCWs.The confidence level in the diagnosis of Mpox was associated with the HCWs’age(P value=0.009),sex(P value<0.001),work experience(P value=0.002),and residence(P value<0.001).The confidence level to treat Mpox was significantly associated with the HCWs’age(P value=0.050),sex(P value<0.001),education(P value=0.033)and occupation(P value=0.005).The confidence level to prevent Mpox was associated with the HCWs’education(P value<0.001),work experience(P value=0.002),residence(P value<0.001)and type of work institution(P value=0.003).CONCLUSION This study revealed that HCWs have the lowest level of knowledge regarding Mpox and a lack of confidence in the ability to diagnose,treat or prevent it.There is an urgent need to organize continuing medical education programs on Mpox epidemiology and preparedness for Burundi HCWs.We encourage future researchers to assess potential hesitancy toward Mpox vaccination and its associated factors.
文摘[Objective]Under the combined impact of climate change and urbanization,urban rainstorm flood disasters occur frequently,seriously restricting urban safety and sustainable development.Relying on traditional grey infrastructure such as pipe networks for urban stormwater management is not enough to deal with urban rainstorm flood disasters under extreme rainfall events.The integration of green,grey and blue systems(GGB-integrated system)is gradually gaining recognition in the field of global flood prevention.It is necessary to further clarify the connotation,technical and engineering implementation strategies of the GGB-integrated system,to provide support for the resilient city construction.[Methods]Through literature retrieval and analysis,the relevant research and progress related to the layout optimization and joint scheduling optimization of the GGBintegrated system were systematically reviewed.In response to existing limitations and future engineering application requirements,key supporting technologies including the utilization of overground emergency storage spaces,safety protection of underground important infrastructure and multi-departmental collaboration,were proposed.A layout optimization framework and a joint scheduling framework for the GGB-integrated system were also developed.[Results]Current research on layout optimization predominantly focuses on the integration of green system and grey system,with relatively fewer studies incorporating blue system infrastructure into the optimization process.Moreover,these studies tend to be on a smaller scale with simpler scenarios,which do not fully capture the complexity of real-world systems.Additionally,optimization objective tend to prioritize environmental and economic goals,while social and ecological factors are less frequently considered.Current research on joint scheduling optimization is often limited to small-scale plots,with insufficient attention paid to the entire system.There is a deficiency in method for real-time,automated determination of optimal control strategies for combinations of multiple system facilities based on actual rainfall-runoff processes.Additionally,the application of emergency facilities during extreme conditions is not sufficiently addressed.Furthermore,both layout optimization and joint scheduling optimization lack consideration of the mute feed effect of flood and waterlogging in urban,watershed and regional scales.[Conclusion]Future research needs to improve the theoretical framework for layout optimization and joint scheduling optimization of GGB-integrated system.Through the comprehensive application of the Internet of things,artificial intelligence,coupling model development,multi-scale analysis,multi-scenario simulation,and the establishment of multi-departmental collaboration mechanisms,it can enhance the flood resilience of urban areas in response to rainfall events of varying intensities,particularly extreme rainfall events.

文摘In the face of disasters,a strong organizational network is the foundation for eff ectively accomplishing emergency relief tasks.In an emergency response network comprising tasks and organizations,the failure of certain organizations may cause large systemic losses owing to internal component associations.To analyze the response system’s robustness,we developed emergency response networks based on the associations between organizations and tasks.A cascading failure model was established considering task reassignment after organizational failure,and indicators in terms of tasks and structures were identified to observe robustness.In the proposed model,we developed random,bond-based,and bridge-based organizational failure modes,and average,capacity-based,and surplus-based reassignment programs.To validate the model,simulation experiments were conducted in the context of extreme rainstorms.The results show that bridge-based failures were the most damaging to network systems,and the average reassignment program was the least eff ective.The analysis of model parameters illustrates the critical eff ectiveness of individual organizational capability in enhancing system robustness.The proposed framework and model enrich the study of emergency response networks with favorable applicability,and the results can provide theoretical references for emergency management practices.
