This paper presented a case study on performance analysis of ground water-source heat pump system (GWHP) for a hotel building retrofit. Splitting air-conditioner was used for cooling and coal fired boiler was used for heating in original system. The GWHP system could save electricity energy and...

Particle-phase polycyclic aromatic hydrocarbon (PAHs) accounts for a large proportion of hazardous compounds in PM2.5 derived from vehicle emission. This study aimed at determining the profiles of PAHs based on tunnel measurement and urban roadside observation. The real-world vehicle emission...

How to reuse waste materials has been one of the most important problems that China has to address. Compared with foreign countries, the overall recovery ratio of waste materials in China is still at a low level, and there is still a giant gap between China and foreign countries on laws and...

Since the United States at first established Deposit Insurance System (DIS) in 1934, over 100 countries have already built up the system so far according to their own national conditions. Although China didn’t implement DIS yet, preparation works have been in progress. In the ‘China...

For spectrally negative Lévy processes, we find expressions of potential measures that are discounted by their joint occupation times over semi-infinite intervals (−∞,0) and (0,∞). These expressions are in terms of the associated scale functions and the inverse functions of Laplace exponents.

Nanoplastic pollution has become a potential threat to aquatic ecosystem and the cost-effective technologies for controlling that are still insufficient. Contaminated corncobs from mining area were collected to prepare the functional mesoporous biochar (MBC) and demonstrate the ability to remove...
