Receiving sensitivity of communication system is required to improve as the recent growth of data service in mobile communication. Thus, the interference caused by passive intermodulation (PIM) attracted more attention in the research of mobile communication. On the other hand, point of interface (POI) plays a more and more important role in practical application at recent years, in order to solve...
The effects of cuboid antenna-radome on base station antenna in the mobile communication band are investigated in this paper. The performance of base station antenna with and without radome is studied and compared. Numerical analysis based on the results of measurement under the same condition is presented to illustrate how the parameters of radome affect the performance of antenna. The analysis intends...
Previous understanding of the mechanism of seed ageing is largely based on observations on imbibed seeds rather than dry seeds. The present research was conducted to investigate whether seed ageing has effects on the dry seeds through proteome analysis. Maize (Zea mays cv. Dabaitou) seeds were artificially aged at 50°C (13.58% moisture content) for 5 or 13 days, and the total protein was extracted...
