Achieving higher efficiency and better quality production with appropriate irrigation regimes in silage maize cultivation in soils mixed with Tread Belt urban sludge is a requirement of sustainable agriculture.Therefore, a two-year field study was carried out with three replicates with four different sewage sludge doses (D0: 0 t/ha, D1: 30 t/ha, D2
In order Lotions to explore the mechanism of bionic propulsion and bionic robots, to make up for the limitations of traditional propulsion with a uniform incoming flow, numerical methods are used to couple fluid dynamics and flapping foil motions, and a flapping-fluid coupling self-propulsion calculation model is established in this paper.K is used
In this paper, we propose a novel microstructure fiber with annular core for transmitting optical orbital angular momentum (OAM), and the OAM modes are calculated Motor Carbon Brushes under different structure parameters of the fiber.Compared with the previous hollow step-index ring fiber, the proposed fiber brings higher refractive index contrast
Several ungulate species are showing increasing population patterns within their geographical distribution ranges, leading to constant interactions with other animal species.Varying densities and activities of different ungulates may result in diverse Loveseat impacts on other coexisting species groups, including large numbers of threatened species
