| 1 | New Macroscopic Problematic Fossil from the Early Cambrian Yanjiahe Biota,Yichang,Hubei,China显示文摘Yanjiahella 情报。nov,从在 Yichang 的早寒武纪的 Yanjiahe 生物区系的特殊石块 taxon,湖北省,旁边被描绘:1 ) 一个全面身体计划梗和一个花萼创作了(也在某种类武装) ;2 ) 梗与仔细 spaced,横向的皱纹和一条中间的、纵的山脉;并且 3 ) 与三维的放射的有条纹或刻痕之状态保存的一个花萼,以及在一些标本的可能的 madreporite。能被分到这个类的三种,它是 Y。ancarpa sp。nov, Y。monocarpa sp。nov,和 Y。biscarpa sp。nov。Yanjiahella 以形态学和一些生物结构比得上某些棘皮动物类的动物 taxa,它可能从早早的寒武纪的 Yangtze 站台显示祖先的棘皮动物类的动物系的早进化和多样化。在 Yanjiahe 生物区系的通常认为的棘皮动物类的动物的发现关于 deuterostome 门棘皮类的起源和进化提供重要线索。 | GUO Junfeng LI Yong HAN Huiping OU Qiang ZHOU Jianren ZHENG Yajuan | 2012 | Acta Geologica Sinica(English Edition)2012，86，4： | 5 |
| 2 | Synergistic improvement of nitrogen and phosphorus removal in constructed wetlands by the addition of solid iron substrates and ferrous irons显示文摘Sanjiang Plain is intensively used for rice production,and ditch drainage diffuse pollution prevention is crucial.Groundwater,rich in Fe ions,is the main source of irrigation water in this region.In this study,pyrite and zero-valent iron(ZVI)(sponge iron and iron scraps)were used as substrates to identify the synergistic influence of exogenous Fe^(2+)addition and solid iron substrates on pollutant removal in constructed wetlands.Based on the results,iron substrates hardly improved the ammonia removal,mainly because of the physical structure and oxidation activity.At a hydraulic retention time longer than 8 h,the pollution removal efficiency in the zero-valent iron(ZVI)substrate treatment increased significantly,and the removal of nitrate(NO_(3)^(−)-N)and total phosphorus(TP)in the iron scrap substrate treatment reached about 60%and 70%,respectively.The high-throughput sequencing results showed a significant increase in the abundance of microorganisms involved in denitrification and phosphate accumulation in biofilms on ZVI substrates.The highest diversities of such microorganisms in biofilms on iron scraps were found for denitrifying bacteria(Pseudomonas),nitrate-reducing Fe(II)-oxidizing bacteria(Acidovorax),and Dechloromonas with autotrophic denitrification and phosphate accumulation,with a 43%cumulative abundance.Dechloromonas dominated in the iron sponge substrate treatment.The highest relative abundance of Acidovorax was found in the mixed iron substrate(pyrite,sponge iron,and iron scraps)treatment.The addition of ZVI substrate significantly improved the removal of NO^(3)_(−)-N and TP and reduced the hydraulic retention time through the continuous release of Fe^(2+)and the promotion of microbial growth.When designing constructed wetlands for treating paddy field drainage,the appropriate addition of iron scrap substrates is recommended to enhance the pollutant removal efficiency and shock load resistance of CWs. | Liping Tian Yang Ou Baixing Yan Hui Zhu Huiping Liu Lei Cheng Peng Jiao | 2023 | Fundamental Research2023，3，6： | 1 |

| 4 | Nutritional Elements Related to Leaf Blight of Pearl Plum in Longtan Town显示文摘[Objectives]This study was conducted to investigate the correlation between leaf blight of pearl plum and nutrient elements from the perspective of plant nutrition.[Methods]Branch and leaf samples of pearl plum plants infected by or free of leaf blight and the corresponding 0-30 cm cultivated soil were collected,and statistical analysis was conducted according to the changes in nutrient contents and the incidence of leaf blight,so as to look for nutrients in pearl plum plants associated with leaf blight,as well as soil constraint factors.[Results]Phosphorus,iron and manganese in nutrients may be related to leaf blight,and the factors affecting leaf blight may be the ratios of P/Fe and P/Mn in leaves.[Conclusions]This study provides a basis for further research on the relationship between phosphorus,iron and manganese on the effect of leaf blight in pearl plum trees. | Xiaohui ZHU Jinsheng HUANG Yan ZENG Liuqiang ZHOU Rulin XIE Jiayu PENG Huiping OU Zhongning LI Hongmei LU | 2022 | Agricultural Biotechnology2022，11，4： | 0 |
| 5 | Analytical solutions of citrate-phosphate coupled model of rice(Oryza sativa L.)roots显示文摘The citrate secreted by the rice(Oryza sativa L.)roots will promote the absorption of phosphate,and this process is described by the Kirk model.In our work,the Kirk model is divided into citrate sub-model and phosphate sub-model.In the citrate sub-model,we obtain the analytical solution of citrate with the Laplace transform,inverse Laplace transform and convolution theorem.The citrate solution is substituted into the phosphate sub-model,and the analytical solution of phosphate is obtained by the separation variable method.The existence of the solutions can be proved by the comparison test,the Weierstrass M-test and the Abel discriminating method. | Huiping Zhang Sbuyue Wang Zhonghui Ou | 2020 | International Journal of Biomathematics2020，13，7： | 0 |
