Characteristics of the Fish Assemblage in the Intertidal Salt Marsh and Mudflat of the Yangtze Estuary

Open Journal of Marine Science 2019年第1期9卷 49-63页

作者： Heng Zhang Jingyu Ye xuehui wang Shenglong Yang East China Sea Fisheries Research Institute Chinese Academy of Fishery Sciences Shanghai China Key Laboratory of Open-Sea Fishery Development Ministry of Agriculture Guangzhou China College of Marine Sciences Shanghai Ocean University Shanghai China State Key Laboratory of Estuarine and Coastal Research Shanghai China

During July 2015 to June 2016, two permanent sampling sites were established in Scirpus mariqueter salt marsh and its adjacent mudflat on the intertidal zone of Chongming-Dongtan in the Yangtze Estuary. Based on monthly trap net surveys of fishes, the characteristics of the fish assemblages in the different subhabitats, including the salt marsh and mudflat, and the monthly variations were analyzed. A total of 19 species of fishes were found belong to 12 Families. The characteristics including the dominant fish species were different in these two subhabitats. 18 species of fish were recorded in the mudflat, of which the dominant species were the Coilia ectenes, Pelteobagrus nitidus and Lateolabrax maculatus. Ten species of fish were recorded in the salt marsh of which the dominant species were the Coilia ectenes, Saurogobio dumerili, Liza haematocheila, Lateolabrax maculatus and Acanthogobius ommaturus. Pelteobagrus nitidus prefers to use the mudflat, while Lateolabrax maculatus and Liza haematocheila prefer to use the salt marsh. There was a significant difference in the monthly variation of fish abundance between the fish abundance of salt marsh and mudflat, while there was no significant difference in fish biomass. The Simpson index of the fish of the mudflat was significantly higher than that of the salt marsh, while the Margalef index and the Pielou index were lower than the salt marsh. The community can be divided into two groups: winter-spring (A) and summer-autumn (B). The abundance of fish in the mudflat and the salt marsh show a very significant correlation with the water temperature (r = 0.773, 0.830, respectively) and a significant correlation with the water salinity(r = 0.654, 0.648, respectively). The abundance of fish in mudflat and salt marsh are both significantly correlated with water temperature and salinity. The abundance of fish of the mudflat (r = 0.470, P > 0.05) is more related to the highest submerged depth than of the salt marsh (r = 0.087,

Chinese Optics Letters 2021年第1期19卷 75-79页

作者： Danyang Shen Jing Qian Chengwei wang Guande wang xuehui wang Quanzhong Zhao State Key Laboratory of High Field Laser Physics Shanghai Institute of Optics and Fine MechanicsChinese Academy of SciencesShanghai 201800China Center of Materials Science and Optoelectronics Engineering University of Chinese Academy of SciencesBeijing 100049China Technology Center Huagong Laser Engineering Co.Ltd.Wuhan 430000China

One-step precipitation of Ag nanoparticles in Ag+-doped silicate glasses was achieved through a focused picosecond laser with a high repetition rate. Absorption spectra and transmission electron microscopy(TEM) confirmed that metallic Ag nanoparticles were precipitated within glass samples in the laser-written domain. The surface plasmon absorbance fits well with the experimental absorption spectrum. The nonlinear absorption coefficient β is determined to be 2.47 × 10-14 m/W by fitting the open aperture Z-scan curve, which originated from the intraband transition in the s-p Ag band. The formation mechanism of Ag-glass nanocomposites is discussed as well.

慢性病老年人具有多维脆弱性的特征。引入脆弱性理论视角,基于世界粮食计划署“风险因素-抵御风险能力-社会服务体系”的脆弱性分析框架,从健康、经济、社会、生活等多个维度构建了反映慢性病老年人脆弱程度的评价指标体系及评估模型。研究发现:随着年龄的增加,慢性病老年男性和女性的脆弱指数均值均呈现上升趋势。在65~80岁年龄组,慢性病老年男性的脆弱指数均值高于老年女性;在80~105岁年龄组,慢性病老年女性的脆弱指数均值总体高于男性。在高脆弱性慢性病老年人中,风险因素致脆型比例最高,面临的风险因素较多及抗风险能力不足是导致其高脆弱的核心诱因;中、低脆弱性慢性病老年人中的社会因素致脆型比例最高。

行政复议与诉讼中的规章:定位区分、立法逻辑与适用展开

《行政复议法》和《行政诉讼法》分别将规章定位为“审理依据”和“审理参照”,这种定位差异是由规章在我国规范体系中的“尴尬”位置所导致的。从立法逻辑来看,行政诉讼是司法权的行使,行政复议是行政权的行使,司法权与行政权的性质、关系以及行政权的内部关系,决定了这种区分的必要性,而立法的妥协性使得这种区分仅限于规章,不包括行政法规和规范性文件。然而,从法律适用的逻辑来看,在《立法法》关于法律规范位阶规定的限制下,行政诉讼中“参照规章”和“依据行政法规”之间在“拒绝适用”上并没有本质区别,二者区分的实质在于合法性假定程度和审查强度的不同。为了与行政诉讼中的法律适用规则相衔接,行政复议机关同样需要根据法律规范位阶进行法律适用。基于行政权的内部关系,应当参照《行政复议法》对于规范性文件的合法性处理机制对行政规章进行相应处理。

在证成"扩大受案范围后的行政诉讼制度是更好的制度"这一命题的核心理由中,以效率价值为基础的制度经济学论证处于重要的地位;行政诉讼制度的核心价值并不是使纠纷解决成本这类静态成本最小化,最为重要的在于通过制度设计来"复制市场",模拟相对人与行政机关交易的市场机制来促进动态效率的实现,理想的行政诉讼制度应是发现有效率判决的复杂系统,而不是仅具有缩小诉讼成本功能的简单技术系统;扩大受案范围的行政诉讼制度是更好的制度,更好的标准是有利于促进制度经济学上动态的配置效率的实现。

批示传统在中国由来已久,是非常重要的"本土资源"。现实中行政批示的性质定位模糊,功能发挥不够。需要分析行政批示行为的类型、法律性质以及对批示行为的法律规制问题,建立行政批示的"内部备案审查制度"和"内部问责制度",确立对"个案批示"的诉讼救济制度,挖掘被既有理论所遮蔽的丰富的行政批示现象。行政批示行为应当纳入行政法治秩序的治理范围。

作者： Weiying Li Hui wang Baitang Lai xuehui Yang Chunyan Zhang Beijing Tuberculosis and Thoracic Tumor Research Institute Beijing 101149 China

Objective: The aim of the study was to explore the effects of the same target (si-10) on lung cancer cells with different expression levels of cyclooxygenase-2 (COX-2) protein by RNAi and malignant proliferation of these cells. Methods: COX-2 was selected as the target and one siRNA expression vector with the best effect was selected and thought as the subject from three COX-2 siRNA expression vectors with human U6 promoter. The siRNA expression vector (psi-10) and the vacant vector (pEGFP) were transfected into these cells with different COX-2 expression states (801D, A549 and LTEP-A2) with lipofectamine respectively and the transfected cell strains were constructed. The change of COX-2 expression levels was examined by Western blot and RT-PCR. The effects on the proliferation of lung cancer cells were studied by cell growth curve and clonogenic assay. Results: The siRNA and U6 promoter were validated by PCR, restriction endonucleases identification and DNA sequencing and BLAST alignment and cloned into the pEGFP vector. The cell strains transfected that 801D was used as maternal line were named as 801D-p and 801D-10 respectively. The cell strains transfected that A549 was used as maternal line were named as A549-p and A549-10 respectively. The cell strains transfected that LTEP-A2 was used as maternal line were named as LTEP-A2-p and LTEP-A2-10 respectively. These cells transfected pEGFP (801D-p, A549-p and LTEP-A2-p) had the expression of GFP and 801D-10, A549-10 and LTEP-A2-10 cells had not in 24, 48 and 72 hours after transfected. The results of RT-PCR and Western blot showed the siRNA expression vector produced marked effects in two cells (A549 and LTEP-A2) expressing COX-2 and the expression of COX-2 was inhibited. But the inhibited effects were differ- ent and the expression of COX-2 was more inhibited obviously in LTEP-A2 cells than in A549 cells though the expression of COX-2 was also inhibited obviously in A549 cells. In contract to their maternal line, t

为分析反倾边坡倾倒变形影响因子敏感性差异,本文采用数值模拟与灰色关联相结合的方法进行研究。首先将边坡几何特征参数、岩体物理力学参数、岩层力学参数定为反倾边坡第一级倾倒变形影响因子,并从各一级因子中进一步划分出边坡坡度、岩层倾角、岩层柔度等12个次级影响因子;然后对各二级影响因子分别选取11个水平数,并将12个二级影响因子、11级水平数随机组合成11套数值模拟方案,采用UDEC进行各方案数值模拟分析;最后,采用灰色关联理论以坡顶倾倒变形水平位移为参考序列对12个二级影响因子进行关联度计算,并进一步分析出了3个一级影响因子敏感性大小。研究结果表明:(1)12个二级影响因子对倾倒变形影响最大的是岩层倾角;(2)三个一级影响因子中几何特征参数对倾倒变形影响最大,岩层层理力学参数对反倾边坡变形影响次之,岩块物理力学参数对反倾边坡变形影响最小。
