Global warming augments the risk of adverse pregnancy outcomes in vulnerable expectant mothers. Pioneering investigations into heat stress (HS) have predominantly centered on its direct impact reproductive functions, while potential roles gut microbiota, despite significant influence distant tissues, remain largely unexplored. Our understanding deleterious mechanisms HS and development effective intervention strategies to mitigate detrimental impacts are still limited.
Abstract. To improve the performance of calibration model for air quality monitoring, a low-cost multi-parameter monitoring system (LCS) based on different machine learning algorithms is proposed. The LCS can measure particulate matter (PM2.5 and PM10) gas pollutants (SO2, NO2, CO O3) simultaneously. multi-input multi-output (MIMO) prediction developed original signals sensors, ambient temperature (T) relative humidity (RH), measurements reference instrumentations. (RF, MLR, KNN, BP, GA–BP)...
This paper presents the design method using topology optimization and fabricating feasibility Fused Deposition Modeling (FDM) 3D printing technique for Functionally Graded Material (FGM) insulator. The concepts of FGM are primarily introduced. And a approach based on COMSOL Multiphisics is proposed. objective to uniform electric field (E-field) inside/along insulator surface high electrical withstanding strength. As result, proper distribution permittivity inside obtained maximum value E...
Surface charge accumulated on insulators plays an important role in flashover process vacuum, which has not yet been fully understood. In this paper, charging behaviors insulator surface were experimentally examined under negative DC and impulse voltage. For the case of voltage, two stages observed, i.e., area near cathode was at first negatively charged lower voltage (stage I) then followed by a positively cathode-anode II). stage I is considered to be caused Schottky injection homo-charges...
Physical thickness of low-density polyethylene (LDPE) films might determine the release rate phthalic acid esters (PAEs) & structural integrity and affect production efficiency. However, this critical issue is still unclear little reported. Aging effects were evaluated in LDPE with 0.006, 0.008, 0.010 0.015 mm a maize field irrigation region. The Scanning electron microscope (SEM) results showed that proportion damaged area (Dam) to total was massively lowered increasing after aging. highest...
This study assesses the urban microclimate characteristics that influence typical residential districts in relation to district planning and design. uses ENVI-met numerical simulation technology compare differences of five city Luoyang, China. A similar scale was used for these districts, but with different architectural designs space layouts. Based on same environmental climatic conditions, layout areas – building heights, densities, greening water surface pavements were shown have...
Wearable sensors face significant challenges in resisting water interference, especially during activities such as rainy-day monitoring, underwater rescue, and ocean exploration, due to their vulnerability moist environments. Exposure to...
The temporal behaviors of charging on insulator surface at flashover initial stage is studied under dc voltage in vacuum. It suggests that the process develops synchronously with multipactor phenomena. A saturated region firstly formed nearby cathode triple junction (CTJ), and charged gradually from toward anode as forward. charge density increases linearly applied electric field, but a stronger field will slow down velocity results violent collisions secondaries dielectric due to normal...
The luminescence evolution phenomena from alumina ceramic surface in vacuum under high voltage of direct and alternating current are reported, with the covering a large range far below to close flashover voltage. Its time resolved spatial distributed behaviors examined by photon counting system an electron-multiplying charge-coupled device (EMCCD) together digital camera, respectively. before exhibits two stages as increasing, i.e., relative low (Stage A), is ascribed radiative recombination...
Corner-tube boiler is widely used in the production of industrial steam. For this boiler, it difficult to conduct hydrodynamic calculation and check due unique water cycle structure. A new method for corner-tube steam based on differential pressure solution proposed article. The frictional drop lower header has been taken into consideration by adding a direction discriminant factor, which can solve inherent problem about balance point. Meanwhile, taking 75 tonne per hour as an example,...
Wildfires are important natural drivers of forest stands dynamics, strongly affecting their regeneration and providing ecosystem services. This paper presents a comprehensive analysis spatiotemporal burnt area (BA) patterns in the Middle Volga region Russian Federation from 2000 to 2022, using remote sensing time series data considering influence climatic factors on fires. To assess temporal trends, Mann–Kendall nonparametric statistical test Theil–Sen’s slope estimator were applied...
