It is generally understood that foxtail millet and broomcorn were initially domesticated in Northern China where they eventually became the dominant plant food crops. The rarity of older archaeological sites archaeobotanical work region, however, renders both origins these plants their processes domestication poorly understood. Here we present ancient starch grain assemblages recovered from cultural deposits, including carbonized residues adhering to an early pottery sherd as well grinding...
Poor preservation of plant macroremains in the acid soils southern subtropical China has hampered understanding prehistoric diets region and spread domesticated rice southwards from Yangtze River region. According to records ancient books archaeological discoveries historical sites, it is presumed that roots tubers were staple foods this before agriculture was widely practiced. But no direct evidences provided test hypothesis. Here we present evidence starch phytolith analyses samples...
<title>Abstract</title> Multiple-microwave-photon transition is a nonlinear process involving the simultaneous absorption of multiple microwave photons to reach higher energy state. This phenomenon enables frequency conversion, crucial technique for spin-wave devices, synthesizers and communication devices. However, it has not been observed in nitrogen-vacancy (NV) centers diamonds, which serve as key quantum platform linking flying qubits, photons, solid-state spins. In this work, we first...
Soil heavy metal pollution including Cd, is the main factor that causes decline of ecological environment quality, excessive content in crops and harm to human health. Phytoremediation one important ways control metals, which has both economic benefits. However, most plant species have limited remediation ability cannot achieve good removal effect. In contrast, P. hydridum , easy cultivate, large biomass short growth cycle, shows strong restoration treatment polluted soil. order explore its...
Exploring the cross-sensitivity between land use transformation and ecological service values in rare earth mining areas is of great significance for development protection restoration areas. To study impact changes on ecosystem functions areas, firstly, change trends area from 2009 to 2019 were analyzed using transfer matrix; then distribution flow direction measured based value equivalents; a spatial autocorrelation analysis was done explore their patterns; finally, coefficient used...
Abstract. Climate warming increases the intensity of extreme precipitation. Studying precipitation patterns and changes is vital to reducing risk. This paper investigates thresholds, timescales for using sub-daily records from meteorological stations in Ganjiang River basin. We use gamma distribution select L-moment method estimate parameters α β. Results show that (1) continuous events 36 h contributed most total but with lower frequency, which would be key flood monitoring; (2) occasional...
Stone knives were used widely in N eolithic E ast A sia, presumably the harvesting of grain crops, but their function has not been clearly understood due to lack study residues from these tools. To address this issue, starch analysis was employed on surface ancient stone and large amounts starches recovered. The sources starches, however, well understood, because crops involves cutting stems rather than direct contact with starchy seeds. determine whether could deposit types residues, we...
Adaptive remeshing technique based finite element model of friction stir welding was used for the investigation tool forces in processes. Results indicate that maximum occur at initial time translational stage. In three directions, axial force is maximum. The direction perpendicular to line minimum. directions are all increased with increase transverse speed and decreased angular velocity.
The relationship between regional human development and geographic environment is the basis for dynamic social change, studying evolution of human-land relations in typical regions can provide background knowledge global change studies. This study based on GIS spatio-temporal statistical techniques, combined with analysis toponymic cultural landscapes, to ethnic minority southeastern China. results show that: (1) geographical region will affect naming villages, orientation family name are...
Due to high risk of unstable supply from fossil energy and growing concern with the preservation environment, well-developed Jiangsu province in China is hungering for alternative resources catalyze stupendous economic growth. Assessing technically available potential solar spatially temporally over whole might be able improve unfavorable situation. This paper presented a GIS based scenario model assessing roof-mounted resource. Its implementation gave an estimation that annual electrical...
Lake carbon burial is of vital significance in global cycle and budget, particularly the large deepwater lakes. However, lakes hard to estimate due difficulty obtaining high spatial-resolution samples. In this study, we investigated distributions total organic (TOC) inorganic (TIC), two main components lake sediments, based on dozens surficial sedimentary samples ( n = 26) covering whole Qinghai, largest saline China. The results showed that TOC content, with a range 1.4–4.8%, was...
Ecological pattern evolution of Poyang Lake wetland, the largest freshwater lake in China, is critical for regional ecological protection and sustainable development migratory bird habitats; however, this information still not fully explored. In study, we quantitatively reconstructed spatial distribution landscape wetlands three periods past 100 years based on military topographic map 1930s Landsat satellite remote sensing image data 1979 2021. Further, use Fragstats software to analyze...
Abstract The morphology and ultrastructure of the venom apparatus endoparasitoid wasp, Opius caricivorae Fischer (Hymenoptera: Braconidae), were observed using light electron microscopes. consists one reservoir several gland filaments. filaments join together at end consist an outer single layer secretory cells, a degenerated epidermal inner intima that encloses lumen. cells are organelle rich, with abundant rough endoplasmic reticulum, mitochondria, vacuole, in which vesicular organelles...
