This study aims to explore the effects of spray processes with four different disinfectants on airborne culturable and pathogenic microbial concentrations, community compositions health risk assessments in chicken houses. Results indicate that compared concentrations before spraying, hypochlorous acid, glutaraldehyde-decamethonium bromide sodium dichloroisocyanate increase bacteria, fungi, Staphylococcus Candida albicans, respectively. Beyond that, have no significant concentrations. The...
The Himalaya orogenic belt produces frequent large earthquakes that affect population centers along a length of over 2500 km. 2015 Gorkha, Nepal earthquake (Mw 7.8) ruptured the Main Himalayan Thrust (MHT) and allows direct measurements behavior continental collision zone. We study MHT using seismic waveforms recorded by local stations completely cover aftershock exhibits clear lateral variation geologic strike, with Lesser ramp having moderate dip on beneath mainshock area flatter deeper...
Abstract The 25 April 2015, M w 7.8 Gorkha, Nepal, earthquake ruptured a shallow section of the Indian‐Eurasian plate boundary by reverse faulting with NNE‐SSW compression, consistent direction current continental collision. Gorkha main shock and aftershocks were recorded permanent global regional arrays temporary local broadband array near China‐Nepal border deployed prior to shock. We relocate 272 earthquakes >3.5 applying multiscale double‐difference relocation technique arrival times...
The comprehensive analysis of geological setting, accumulation condition, trapping mechanism and distribution regularity oil-gas the Upper Triassic in Sichuan Basin reveals that gas Xujiahe Formation is a layered lithologic giant province. Coal source rocks layers expelled hydrocarbon evaporatively. Under setting episodic fold-thrusting compression boundary orogen, multi-sources charged quickly formed coarse deltaic environment with large-scale delta plain small-scale front. In gentle...
SUMMARY Resolving the detail of crustal deformation seismically and technically active Sichuan-Yunnan block located in southeast margin Tibetan Plateau is crucial for understanding lateral extrusion Plateau. Using seismic data from two regional seismograph stations China Earthquake Networks Center twenty recently deployed broad-band temporary MCD Array (Middle ChuanDian array), we constrained thickness anisotropy at west boundary block, near east Himalayan syntaxis by receiver function...
Based on the analysis of outcrop, seismic, logging and drilling data, combined with exploration practice, characteristics, distribution, reservoir performance gas-bearing properties Permian igneous rocks in Sichuan Basin are studied. The study shows that central volcanic eruptive facies developed Basin, their lithological assemblages distribution characteristics show obvious differences. mainly distributed three regions: southwestern part basin has dominantly large- scale overflow basalts;...
Abstract The Qiangtang terrane exhibits many unique features compared with surrounding areas in the Tibetan plateau. It has been largely remodeled by northward downwelling of Indian lithosphere and vertical upwelling Eurasian asthenosphere. Here, we investigate P ‐wave velocity around mantle transition zone (MTZ) beneath using high‐frequency triplicated waveforms recorded China Digital Seismic Network. We found a low‐velocity layer (LVL) atop MTZ high‐velocity anomaly (HVA) lower part MTZ....
Abstract A low-velocity layer atop the mantle transition zone has been extensively observed worldwide. In subduction zones, this is widely explained as partial melting triggered by slab on a regional or global scale. However, direct observational evidence still absent, and response of to not well known. Here, we image seismic velocity around matching synthetic triplicated P sP waveforms in Indian–Eurasian continental zone. Our observations reveal laterally varied beneath Hindu Kush, where...
In nuclear power systems, centrifugal pumps often need to operate under extreme conditions. However, accurately determining the cavitation status of such conditions is challenging. To improve recognition accuracy three statuses non-cavitation, incipient cavitation, and severe while improving anti-interference capability monitoring system, this study extracted features from pumps’ motor current vibration signals different operational It fused using feature-level multi-source information...
The Sichuan Basin represents the earliest area where natural gas is explored, developed and comprehensively utilized in China. After over 50 years of oil exploration, reservoirs have been discovered 24 gas-dominant layers this basin. For purpose predicting exploration direction target each layer Basin, sedimentary characteristics marine continental strata basin were summarized forms multi-cycled tectonic movement their controlling effect on sedimentation, diagenesis hydrocarbon accumulation...
AbstractAbstractTitanium carbide based cermets with additions of titanium nitride nanoparticles were fabricated by using ultrasonic dispersion and conventional powder metallurgy techniques. In order to characterise the microstructure, SEM TEM have been utilised. The results show that microstructure becomes finer increasing nanoparticles. mechanical properties also measured do not change monotonously amount nanoparticle addition. Good can be obtained when TiN addition reaches 6 - 8 wt-%....
The initial growth stage of the single-crystalline Sb and Co nanowires with preferential orientation was studied, which were synthesized in porous anodic alumina membranes by pulsed electrodeposition technique. It revealed that is a three-dimensional nucleation process, then gradually transforms to two-dimensional via progressive mechanism, resulting structure transition from polycrystalline single crystalline. competition among nuclei inside nanoscaled-confined channel kinetics responsible...
On September 5, 2022, at Beijing time 12:52 p.m., an MS 6.8 earthquake struck Luding County, Garze Tibetan Autonomous Prefecture, Sichuan Province. The epicenter of the was intersection Sichuan-Yunnan, Bayankala, and South China blocks. tectonic background is extremely complex, strong earthquakes occur frequently. Based on a predetermined focal location mechanism solution for earthquake, we reversed depth rupture process by fitting teleseismic P SH waves recorded global seismic network....
