Cadmium sorption behavior of granular activated carbon oxidized with nitric acid was systematically studied by sets of the equilibrium and time-based experiments under various conditions. The cadmium adsorption capacity of oxidized granular activated carbon enlarged with an increase in pH, and reduced with an increase in ionic strength. Experimental data were evaluated to find out kinetic characteristics. Adsorption processes were found to follow pseudo-second order rate equation. Adsorption isotherms correlate well with the Langmuir isotherm model and the maximum sorption capacity of cadmium evaluated is 51.02 μmol/g. Thermodynamic parameters were calculated based on Van＇t Hoff equation. Equilibrium constant Kd was evaluated from Freundlich isotherm model constants, Langmuir isotherm model constants, and isotherms, respectively. The average change of standard adsorption heat ΔH^0 was -25.29 kJ/mol. Negative ΔH^0 and ΔG^0 values indicate the adsorption process for cadmium onto the studied activated carbon is exothermic and spontaneous. The standard entropy ΔS^0 was also negative, which suggests a decrease in the freedom of the system.

Besides amplitude, frequency and phase, the polarization is another basic property of the electromagnetic wave. In the remote sensing field, the polarization is mainly applied in active detection systems of radar and lidar. This paper presents the quantitative relationship between soil moisture and polarization signatures in a certain type of soil in a farm. And this relationship is expected to be introduced on agriculture and hydrology ultimately. The experiments were performed both in the laboratory and the field. Soil samples with different moisture contents were measured at three wavebands on visible spectrum, and at several viewing angles in the plane of incidence. The polarization signature was indicated by the multi-band and multi-angle degree of linear polarization (DOLP) in this paper. The soil moisture were divided into five levels according to the properties of DOLP curves, namely, the quasi-quantitative relationship between soil moisture and its polarization signature were established. The percentages of soil moisture of the five levels are: ≤10%, 10%-20%, 20%-40%, 40%-56% and >56%, respectively. Although this division for soil moisture is on a rather large scale, it will meet the precision of application agricultural and hydrologic remote sensing.

多囊卵巢综合征(polycystic ovary syndrome,PCOS)是一种常见的妇科内分泌疾病,患者通常伴有月经失调、不孕、多毛、痤疮和肥胖等临床表现,目前确切的发病机制尚不清楚。近年越来越多的证据显示内质网应激(endoplasmic reticulum stress)参与了PCOS的病理过程,有望成为治疗PCOS的新靶点。内质网应激是内质网的稳态失衡,未折叠或错误折叠的蛋白质在内质网中积累的状态。一定程度的内质网应激有助于卵泡的发育成熟,但持续的内质网应激会诱导颗粒细胞凋亡,并且通过影响类固醇激素代谢、糖代谢和脂质代谢等过程导致PCOS患者卵泡发育异常、性激素及胰岛素合成分泌紊乱,从而对女性生育能力造成不利影响。综述内质网应激与PCOS各种致病因素之间的关系,以期为PCOS的病因学研究和治疗提供新思路。
