An experiment was carried out to compare cadmium and copper absorption and mineral nutrition accumulation in pennisetum and tall fescue in order to select an appropriate grass to remediate Cd/Cu-contaminated soil and explore their detoxification mechanisms of contamination by mineral elements. The biomass remained constant in tall fescue under each Cd addition level and increased in pennisetum until...
As energy crises and environmental pollution become increasingly prominent, people are beginning to explore the ocean to exploit its renewable energy. Based on hydrodynamic principles, an analytical model for unstable hydrofoil motion has been developed. The software ANSYS Fluent was employed to perform a simulation of hydrofoil motion, and the effect of hydrofoil motion on the surrounding flow field...
The Shiyang River Basin has been regarded as an important ecological protective area in the Hexi corridor in northwest China. Landsat TM, ETM+, and OLI images in 1986, 2000, 2006, and 2015 were selected as basic data resources, and the circle layers and fan-shaped analysis were applied to extract change information and the characteristics of land use pattern change by a set of transfer and dynamic...
