A certain number of hole-like defects will occur in aluminum alloys under cyclic loading. The internal holes reduce the strength material and cause stress concentration, which aggravate development fatigue damage. classification method defect features based on X-ray CT damage data is proposed. random hole distribution model established through linear congruence region division method. parameter introduced as intermediate variable 3D reconstruction defects. In mesoscopic stage, function...
Globally, tailing impoundment failures frequently occur, making safely held hazardous materials mobile. The pore water within the tailings can have (near-) neutral pH due to acid neutralization before disposal, leading generation of mine drainage (NMD) as it leaks from impoundment. biogeochemical evolution key elements, particularly Fe, and associated mobility toxic trace metals, including arsenic (As), in these NMD scenarios remain insufficiently explored. In this study, we investigated...
Objective: To investigate the levels of lanthanum, cerium, praseodymium, and neodymium in blood, urine, hair samples from residents rare earth mining area a city China, to provide scientific basis for control pollution protection population health. Methods: A total 147 who had lived long time were selected as exposure group, 108 Guyang County this 91 km away group. Blood, collected both groups. Inductively coupled plasma mass spectrometry was used determine content samples. Results: In...
Abstract. Source apportionment of organic aerosol (OA) from mass spectrometer (AMS) or chemical speciation monitor (ACSM) measurements relies largely upon spectral profiles different source emissions. However, the changes in spectra primary emissions AMS/ACSM with newly developed capture vaporizer (CV) are poorly understood. Here we conducted 21 cooking, crop straw, wood, and coal burning experiments to characterize features OA water-soluble (WSOA) using SV-AMS CV-ACSM. Our results show...
A N-iodosuccinimide (NIS)-mediated divergent and efficient tandem reaction between fluorinated propargyl amidines aromatic o-diamines without any metal catalyst additive under mild conditions was developed for the synthesis of benzo-fused bisimidazoles in moderate to excellent yields. Preliminary mechanistic studies suggested that this proceeded by an intermediate secondary amine derived from 5-iodomethyl imidazole, NIS played another role oxidation reagent promote formation a benzimidazole motif.
Abstract Mine water inrush is one of the important factors threatening safe production in mines. The accurate understanding mine groundwater flow field can effectively reduce hazards inrush. Numerical simulation an method to study field. This paper numerically simulates seepage GaoSong ore In order ensure accuracy numerical model, research team completed 3,724 fissure measurements area. fracture measurement results were analyzed using GEOFRAC and whole-area network data generated. On this...
Abstract Water masses are carriers of anthropogenic fingerprints in the ocean interior, with their property changes manifesting oceanic thermodynamic responses to climate change. Yet, delimiting water remains challenging either observational atlas or models. This study analyzes distribution Indian Ocean seawater density–spicity space and uses volumetric maxima minima between σ = 27.1 27.4 kg m −3 track cores boundaries intermediate masses, respectively. In addition well-known Antarctic...
Abstract. Organic aerosols play a significant role in atmospheric chemistry and climate, yet their sources transformations remain poorly characterised over marine regions. This study aims at representing the clean Northeast Atlantic background by presenting first source apportionment of organic (OA) Mace Head, Ireland. Resolved aerosol were prevailing pristine boundary layer air masses, with balanced mass contributions from primary secondary sources. Positive matrix factorisation resolved...
