Concentrations and deposition fluxes of heavy metals in the precipitation of core urban areas of Chongqing were investigated for one year from December 2011 to November 2012. Precipitation samples were collected with an automated precipitation sampler from three sampling sites. Concentrations of 13 heavy metals were analyzed using ICP-MS. Results showed(More)
In this paper, M-ary Quaternary Orthogonal keying modulation (MQOK) is proposed based on the analysis of the common traits of Complementary Code Keying (CCK) and M-ary Bi-orthogonal Keying (MBOK). Besides, CCK is defined as a kind of MQOK. By analyzing the performance of MQOK on the condition of additive white Gaussian noise (AWGN) channel, new closed-form(More)
The mercury (Hg) distribution and storage in plants at water-level-fluctuating zone (WLFZ) in the Three Gorges Reservoir were investigated by analyzing the total mercury(THg) and methylmercury ( MeHg) levels in different parts of plants collected from three typical sites including Shibaozhai, Zhenxi and Hanfeng Lake in WLFZ. The results indicated that THg(More)
A long-term experiment was conducted to evaluate the effect of tillage methods on mercury and methylmercury contents in the purple paddy soil and overlying water. The experiment included five tillage methods: no-tillage and fallow in winter, ridge-no-tillage, compartments-no-tillage, paddy-upland rotation and conventional tillage. The results showed that(More)
Concentrations of mercury (Hg) species in precipitation were measured during the period from April 2013 to March 2014 in Jinyun Mountain, Chongqing, and corresponding deposition fluxes were also estimated. The result showed that the ranges of concentration of total mercury (THg) , dissolved mercury (DHg), particulate mercury (PHg), reactive mercury (RHg),(More)
This paper describes the highly selective, sensitive and topology-specific fluorescent sensing of dimeric G-quadruplexes by a polyether-tethered dimeric berberine 1. Compound 1 displays high selectivity for dimeric G-quadruplexes over monomeric ones, and can be lit up by dimeric G-quadruplexes, in particular by the one linked with one TTA subunit. In(More)
Plentiful plants in the water-level-fluctuation-zone (WLFZ) of Three Gorges Reservoir ( TGR) grow vigorously during the non-flooded period, especially the herbaceous ones. Then, the WLFZ is submerged gradually from the end of September. Soil-plant system that under a long time flooded condition may change the form of mercury, thus resulting in a secondary(More)
This paper is focused on the application of antijamming communications in the military. A new kind of UWB signal named multi-sub-channels multi-time direct sequence spread spectrum which applied in the ultra-short wave is promoted by analyzing and improving the UWB MC-DS-CDMA. The signal's generator model and format are given in the paper. The anti-jamming(More)
Three tetrameric sterol-spermine conjugates were shown to be capable of mediating chloride transport across 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphatidylcholine (POPC)-based liposomal membranes via an anion-exchange mechanism. Of the three conjugates, the one that was derived from deoxycholic acid showed the highest activity. Such anion transporting(More)
