Under a Creative Commons license Open accessAbstract In this paper, we develop a bi–level transferable air pollutant price (TAPP) model, and use the model to find ways to mitigate China’s interprovincial air pollution control problem. In this model, the leader is China’s central government ...
This criterion represents the balance of the break-up force, related to gas kinetic energy through the gas density, ρg, and vg2, that is resisted by melt surface tension, σm, acting over a specific melt stream diameter, do. Generally in each model of droplet formation, a stability crite...
Abstract With rapid urbanization and industrialization, air pollution has emerged as a serious threat to quality crop production. Assessing the effect of the elevated level of pollutants on the performance of the crops is crucial. Compared to the soil and water pollutants, the air pollutants spread ...

The statistical package STATA [35] was used for the analyses (XTGEE; the option "force" was specified in order to allow for unequally spaced observations). All the linear models included the within-subject between-period effect, using the dichotomous season variable (spring and winter). For ...
These exploit a pump or vacuum to force analytes present in the air to flow through a sampler [7]. The sampler can be a trap, such as a tube packed with a bed or multibed of sorbents, for example polyurethane foam (PUF), XAD resin, active carbon, a porous polymer, or graphitised...
However, for AuNi/NPNi/FNi, the ORR occurs on the Au air electrode surface, resulting in the formation of Li2O2 thin films. As can be seen from the above research, regulation of the active material of electrocatalysts can accelerate the reaction kinetics, as well as tuning the structures ...
