Water resources are a key factor restricting human survival and social and economic development.The Miyun Reservoir, which is the only surface drinking water source in Beijing and the water storage reservoir of the South-to-North Water Diversion Project, plays a decisive role in ensuring water-use sustainability of the capital.This study focused on
The implementation of EPR information disclosure responsibility is one of the four key tasks in the implementation of EPR.In order to explore the impact mechanism of carbon information disclosure behavior of manufacturers and remanufacturers considering extended producer responsibility (EPR) and low-carbon preference on corporate profits of outsour
In order to a the flow of the plane flow field induced by the inner rod rotates and revolves in the cylinder, the Fluent software is used to numerically simulate the plane flow field of the eccentric annulus generated by the planetary motion of the rod string and based on the superposition principle.The velocity distribution and secondary flow of t
Ashtrays Overcapacity in prisons often occurs among the elderly from 2019 to 2022.This research aims to address the problem of overcapacity for elderly prisoners in correctional institutions.The method in this research uses a qualitative approach through literature studies.The results of the research show that the overcapacity that occurs every yea
Trapped ions are excellent candidates for quantum computing and quantum networks because of their long coherence times, ability to generate entangled photons as well as high fidelity single- and two-qubit gates.To scale up trapped ion quantum computing, we need a Bell-state analyzer on a reconfigurable platform that can herald high fidelity entangl
