Skin-attachable electronics have garnered considerable research attention in health monitoring and artificial intelligence domains,whereas susceptibility to elec-tromagnetic interference(EMI),heat accumulation issues,and ultraviolet(UV)-induced aging problems pose significant constraints on their potential applications.Here,an ultra-elas-tic,highly breathable,and thermal-comfortable epidermal sensor with exceptional UV-EMI shielding performance and remarkable thermal conductivity is developed for high-fidelity monitoring of multiple human electrophysiological signals.Via filling the elastomeric microfibers with thermally conductive boron nitride nanoparticles and bridging the insulating fiber interfaces by plating Ag nanoparticles(NPs),an interwoven thermal con-ducting fiber network(0.72 W m^(-1) K^(-1))is constructed benefiting from the seamless thermal interfaces,facilitating unimpeded heat dissipation for comfort skin wearing.More excitingly,the elastomeric fiber substrates simultaneously achieve outstanding UV protection(UPF=143.1)and EMI shielding(SET>65,X-band)capabilities owing to the high electrical conductivity and surface plasmon resonance of Ag NPs.Furthermore,an electronic textile prepared by printing liquid metal on the UV-EMI shielding and thermally conductive nonwoven textile is finally utilized as an advanced epidermal sensor,which succeeds in monitoring different electrophysiological signals under vigorous electromagnetic interference.This research paves the way for developing protective and environmentally adaptive epidermal electronics for next-generation health regulation. 展开更多

A MEMS (Micro-Electro-Mechanical System) based thin film semiconductor was fabricated as the gas sensor. To obtain the target gas selective response, the surface of the sensitive film was modified with highly active metal catalytic nano-particles. Thus the anti-interference ability was improved and the false alarm rate was effectively reduced. Furthermore, the modular embedded system for information acquisition and transmission was developed. Supported by the Airflow Precision control system (APs), the rapid warning of volatile gas of flammable substances was realized. Experiments showed that RAs has satisfied selectivity to volatiles of usual flammable liquid, such as the output voltage reaches 3 V (0 - 3.3 V). With simulation about the actual installation state in bus, MWs sounds an alarm at 2 minutes after splashing 50 mL 92# petrol to the floor. For the last two years, FEVMEW has been integrated into more than 4000 buses in Hefei. This design has been proved feasible according to the actual operation. </div> 展开更多

[Objective] The research aimed to monitor and evaluate indoor radon concentration in one district of Xi'an City. r Method] In order to master the effective dose per year caused by natural radiation to local residents, the investigation about the level of indoor radon in one district of Xi'an was developed. Based on the proper monitoring scheme, some typical living rooms were sampled. Through the measurement result, the effects of different factors on radon concentration were obtained. Finally, the radon concentration was transferred into the effective dose per year of local residents. [ Result] Indoor radon concentration in the district was during 49.680 -128.856 Bq/m3, and average concentration in each building was within 100 Bq/m3, which belonged to normal range. When sunny day became rainy day, radon concentration firstly had a rise trend. If continuous rainy weather appeared, indoor radon concentration gradually declined. When other conditions were same, indoor radon concentration under window closing was significantly higher than that under window opening. Indoor radon concentration had a decline trend from 13:00 to 20:00 and a rise trend from 01:00 to 06:00. Condusion The district belonged to radon safety house. To protect residents' health to the maximum extent, according to transfer change rule of the radon, window should be opened to ventilate in the morning when radon concentration was higher. 展开更多

Air pollution is a major global issue with widely known harmful effects on human health and the environment. This pollution is a very complex phenomenon given the diversity of pollutants that may be present in the atmosphere. The air quality in urban areas is of a great concern for residents living in cities and represents a current issue that requires an adequate management. So that air quality policy is driven by health concerns. In this paper, we present an overview on the experience of Agadir city to establish the air quality management policy, local authority on the whole have developed a good understanding of air quality in the area. Indeed for several years, efforts have been made to monitor the air quality in this city, this translated by air quality assessment since 2006 using mobile laboratory and fixed station. Our goals in this study were to review the operation of Local Air Quality Management (LAQM) making better use of available resources to improve its outcomes and make recommendations with a view to improving air quality issues. This work highlights the requirement to revise periodically the LAQM for generating priority for air quality issues within local authority and the need to implement the optimizing Air Quality Monitoring Network (AQMN). 展开更多

In this paper, aiming at the problems of insufficient soil nutrients and high salt content in Wudi core demonstration area of Bohai Granary, a monitoring and management system of water, fertilizer and salt in saline-alkaline farmland based on WebGIS was established in order to monitor and control water, fertilizer and salt. Based on the Windows.NET platform, using B/S mode of operation architecture and Visual Studio 2010 as the software development environment, the related components in ArcGIS Engine were invoked by ArcGIS API for Silverlirht, and the WEB system was developed by C# and XMAL language. Based on the principle of water, fertilizer and salt balance, a monitoring model and a regulation model for water, salt and nutrients were established. Intelligent analysis and application of farmland soil data were realized, and a precision agriculture system with data query, early warning diagnosis, monitoring and control of water, fertilizer and salt was formed. And the "water and salt homologue, water supply due to demand, adequate and multiple" irrigation scheme and the salt and alkali reduction scheme of "synergistic conditioning of agents and nutrients" and a nutrient regulation plan for "stabilizing nitrogen, increasing phosphorus, supplementing potassium at the discretion" and "quick-acting combining slow release" were put forward. Compared with the period without monitoring and control of water and salt, the effect of water saving and fertilizer saving was improved, and the yield of wheat and maize was also significantly increased. It provided guidance for local users to increase crop production and income, and greatly improved the utilization of resources and grain production. 展开更多

Alterations of the autophagy-lysosomal pathway(ALP) and autophagy have been involved in lung ischemia-reperfusion(I/R) injury. However, dynamic imaging of ALP function under lung I/R injury particularly is not fully understood. Here we depicted the live-cell fluorescence imaging of autophagosome to monitor ALP activation and autophagy function. The p As Red2-N1-LC3 vectors were transfected into CRL-2192 NR8383(an alveolar macrophage cell line) and CCL149(an alveolar epithelial cell line) successfully. 0-h, 2-h, 4-h, and 6-h hypoxia/0-h, 2-h, 4-h, and 6-h reoxygenation were then induced with an ALP inhibitor(3-MA) or activator(rapamycin) in the culture of transfected cells separately. ALP activation was conformed by up-regulating AMPK and beclin1 expression. Apoptosis was not obvious in 2-h hypoxia/2-h reoxygenation. p As Red2-N1-LC3 CCL149 and p As Red2-N1-LC3 NR8383 cells revealed gradually enhanced As Red2 from 2-h to 6-h hypoxia/reoxygenation. As Red2 varied sensitively to 3-MA and rapamycin interventions during 2-h hypoxia/reoxygenation. Our data provides a simple method of autophagosome imaging to monitor ALP activation and autophagy function in lung I/R injury. 展开更多

Guyana is an oil-producing country vulnerable to potential oil spills and the environmental risks posed by oil and gas exploration and production activities. Despite the technologically advanced equipment employed by ExxonMobil Guyana and affiliates, an oil spill could occur due to accidents, equipment failures, or sabotages. The selected coastal communities as the study areas in Region 1 and Region 2 could be adversely affected, particularly the mangrove ecosystems. Potential oil spill pollution will adversely impact mangrove ecosystems in Region 1 and Region 2. Mangroves offer significant benefits to coastal communities, such as coastal defence and carbon sequestration, which puts Guyana on the world map. The research aimed to investigate the mitigation strategies to manage the potential environmental risks on mangrove ecosystems in the coastal communities of Region 1 and Region 2. It followed a qualitative approach and conducted semi-structured interviews with the Toshaos of the selected coastal communities. The data analysis strategy was thematic analysis using the Nvivo software. The major themes included legal and policy frameworks, oil spill response strategies, community-based involvement, and monitoring and enforcement of regulations. The significant results included reviewing and updating the regulatory framework for mangrove management and conservation;oil spills mitigation measures such as containment and shoreline protection and cleanup, cost recovery and compensation, and limited monitoring and law enforcement of mangrove management and conservation regulations by inter-agencies. The regulatory and institutional framework is outdated and needs to be amended. The agencies overseeing mangrove management and conservation have overlapping responsibilities and require more coordination. There should be greater collaboration among agencies for mangrove management and conservation and improved monitoring and enforcement programmes through institutional support. 展开更多

With the introduction and development of evidence-based medicine in China, it has been spread rapidly in the area of integrative medicine(IM) and has become a new unique discipline. During almost 20 years, as one of the most important parts of evidence-based IM, systematic review(SR)/meta-analysis(MA) of IM have shown a good development momentum in the aspects of quantity, depth, breadth and influence, but also face the harsh situation of the uncontrolled quantity and quality, especially for SRs in Chinese. Therefore, how to supervise and standardize this area effectively becomes a problem to be solved. Based on the experience both at home and abroad, the authors put forward several kinds of solutions for laying the foundation for further development such as promoting the registration system of SR/MA of IM, effectively setting up the regulatory platform of quality and quantity, launching professional training for SR/MA reviewers, formingqualification registration, developing the data transfer and sharing platform to realize the transparency of evidence process. 展开更多
