Tuberculosis (TB) is one of the major infectious diseases with largest number morbidity and mortality. Based on comparison high low burden countries tuberculosis in China, India United States, influence age-period-cohort incidence three from 1992 to 2017 was studied based Global Disease Study 2017. We trends using Joinpoint regression age-standardized rate (ASIR). The model showed a significant decreasing behavior States between Here, we analyzed India, as well distinguished age, period...
A powder-based 3D printing technology, selective laser sintering (SLS), is a novel strategy of manufacturing complex components with specially tailored properties, including mechanical as well thermal and electrical conductivity. In this study, the effect incorporating Al2O3 particles BN plates on conductivity PA12 composites was investigated. composite powders, which can be applied to SLS, were prepared via two-step approach mixing. Morphology characteristics demonstrated that fillers...
Abstract A facile synthetic method for the preparation of di‐ and trisubstituted pyridines with high regioselectivity through an intramolecular pericyclization strategy is disclosed. The multicomponent reaction isocyanides, arynes, 3‐bromopropyne affords disubstituted in good yields. In contrast, use 3‐acetoxypropyne results formation situ formed azatriene. this way, desirable can be constructed a one‐pot manner.
The disability weight (DW) quantifies the severity of health states from disease sequela and is a pivotal parameter for burden calculation. We conducted national subnational DW measurement in China.In 2020-2021, we web-based survey to assess DWs 206 31 Chinese provinces targeting workers via professional networks. fielded questions paired comparison (PC) population equivalence (PHE). PC data were analysed by probit regression analysis, results anchored PHE responses on scale between 0 (no...
Abstract The main research goal of high‐performance conductive polymer composites is to improve electrical conductivity and reduce the percolation threshold. Designing an effective network one fundamental ways conductivity. In this study, polypropylene composite powders coated with carbon black (CB) graphene nanosheets (GNSs) were prepared by a combination ultrasonic dispersion liquid‐phase deposition, sintered using selective laser sintering process prepare three‐dimensional separated...
Based on identification of fossil charcoals from 11 sites in the Hexi Corridor, we reconstruct local vegetation community and human impact it period 4300 to 2400 cal. yr BP. More than 20 broadleaved taxa 4 coniferous trees are present. The charcoal identifications show that 4300–2400 BP differed regionally because variations topography water supply, with limited diversity northwest Corridor relatively rich southeast area. In oasis woodland consisted mainly Tamarix sp., Salix Populus sp....
The paper explores seasonal movements of Bronze Age mobile pastoralists in the western Tianshan mountainous region Xinjiang, China. Fieldwork by a team from Institute Archaeology Chinese Academy Social Science (CASS) and University Sydney, Australia have identified cyclical land use practices associated with Andronovo cultural complex. Their pattern has been reconstructed through ethnographic studies analysis modern snow grass cover. Using this detailed combination data, study defines...
Located on the Pamir Plateau in Xinjiang Province, China, Ji'erzankale Necropolis dates back to 2500 yr BP. Many materials that have been unearthed this cemetery, including shoo konghou (musical instrument), bronze mirrors and glass beads, suggest cultural transference between East West. Furthermore, small-sized rounded fire altars made from sweet-scented Sabina were found for first time regarded as implements veneration. We identified 70 wooden objects 25 tombs within Necropolis, each...
The question of what the ecology communities Loess Plateau looked like before extensive anthropogenic reshaping processes late-Holocene has stirred a long debate. A better understanding these human-induced changes will not only help us understand extent paleoeconomic practices, but also inform future conservation actions on this ecologically fragile landscape. This paper presents systematic study wood charcoal from series archaeological sites, demonstrating that woody plants and woodlands...
Abstract An aluminum diethyl hypophosphite intercalation‐modified montmorillonite flame retardant (AlPi‐MMT) is successfully prepared and characterized by FT‐IR, SEM, X‐ray diffraction. It found that thermoplastic polyester elastomer (TPEE) composites incorporating 15 wt% AlPi‐MMT exhibited better char formation properties compared to those (4:1, w:w) AlPi MMT. And the residual of TPEE/AlPi‐MMT at 700°C 16.17%, which higher than 13.94%. former can pass UL‐94 V‐0 rating test while latter only...
Abstract The dodecyl sulfate intercalated CaMgAl‐hydrotalcites (layered double hydroxides [LDHs]) were successfully prepared by co‐precipitation method, and characterized X‐ray diffraction analysis, infrared spectroscopy (Fourier transform spectra [FT‐IR]), thermogravimetry (TG‐DTA), scanning electron microscope, Brunner−Emmet−Teller (BET). LDHs added to the intumescent flame retardant (IFR) polypropylene (PP) nanocomposites, limiting oxygen index method (LOI), vertical combustion (UL‐94),...
The mechanisms of the origin and dispersal millet agriculture in northern China are poorly understood. We used plant macroremains, stable isotope compositions human bone collagen, pollen records from Sitai site to reconstruct changes subsistence strategies their relationship with ecological environment early middle Holocene on Inner Mongolian Plateau China. Charred weed-like seeds, bones small mammals, eggshell fragments, together microliths, indicate practice hunter-gatherer during...
Abstract. Due largely to demographic growth, agricultural populations during the Holocene became increasingly more impactful ecosystem engineers. Multidisciplinary research has revealed a deep history of human–environmental dynamics; however, these pre-modern anthropogenic transformations and cultural adaptions are still poorly understood. Here, we synthesis anthracological data explore complex array interactions in regions prehistoric Silk Road. Our results suggest that ancient humans were...
Abstract This paper aims to improve the tensile strength and thermal stability performance of selective laser sintered thermoplastic polyurethane elastomer/spherical alumina/graphene oxide/silicon nitride whisker (TPU/Al 2 O 3 /GO/Si N 4 ws) composites by investigating synergistic enhancement fillers with different dimensions, solving problem excessive porosity, material delamination, low during sintering semi‐crystalline polymer TPU problems. The results show that effect multidimensional...
Abstract To address the shortcomings of large porosity and insufficient mechanical properties skeletonized Thermoplastic polyurethane (TPU) fabrications during preparation composite materials by selective laser sintering (SLS) technology. In this paper, SiO 2 @Si 3 N 4 ws‐GPTMS core‐shell structure filler was successfully prepared first synthetically growing silicon dioxide (SiO ) nanospheres on surface nitride whiskers (Si ws) in situ sol–gel method, then modified with silane coupling agent...
Abstract Early Palaeolithic wooden implements are exceptionally rare. The best known the spears and throwing sticks from Schöningen, Germany dated to ca. 300–330 thousand years (kyr) ago 1,2 171-kyr old digging Poggetti Vecchi, Italy 3 . Here, we report a unique assemblage of 35 site Gantangqing, southwestern China, which was found associated with stone tools, antler soft hammers cut-marked bones, is 361–250 kyr at 95% probability. include complete, small, hand-held pointed tools. tips...
