1Morphological evolution of mouth bars on the Yangtze estuarine waterways in the last 100 years显示文摘在 Yangtze 河口水路的嘴酒吧在河口,洪水分泌物和上海港口的建设以内在航行运输上有重要影响。在这份报纸, Yangtze 河口水路的嘴酒吧形成的词法进化和机制被分析几百年历史的数据学习,一些或主要的嘴的最近的侧面地图在 Yangtze 河口锁隧道。结果如下被显示出:在北方布朗奇的嘴酒吧从在嘴外面逐渐地搬到里面并且形成了一个巨大的沙酒吧。在北方隧道,嘴酒吧的头下游地移植了大约 30 公里,并且自从 2001,一个隧道酒吧发展中。二个嘴酒吧顶,总是在北方经过存在,消失在 2010。在南方经过的嘴酒吧的头下游地移植了大约 14 km,顶的数字起初增加了,但是现在被归结为仅仅。根据结果,我们能断定嘴酒吧的进化不同取决于他们的地点。在它是的北方布朗奇,直接,与在 Chongming 岛的大规模开垦有关,但是在诺思经过,它与 Yangtze 河口深海的隧道的规定有一种靠近的关系。然而,在北方隧道和南方经过的嘴酒吧的进化是不仅在浅的东方 Hengsha 和 Qingcaosha 水库的闭合与 Yangtze 河口深海的隧道规定工程,而且与开垦连接了。HE Yufang CHENG Heqin CHEN Jiyu 2013Journal of Geographical Sciences2013,23,2:9
2Coordinated control of coastal multi-source multi-load system with desalination load: a review显示文摘Traditional seawater desalination requires high amounts of energy, with correspondingly high costs and limited benefits, hindering wider applications of the process. To further improve the comprehensive economic benefits of seawater desalination, the desalination load can be combined with renewable energy sources such as solar energy, wind energy, and ocean energy or with the power grid to ensure its effective regulation. Utilizing energy internet(EI) technology, energy balance demand of the regional power grid, and coordinated control between coastal multi-source multi-load and regional distribution network with desalination load is reviewed herein. Several key technologies, including coordinated control of coastal multi-source multi-load system with seawater desalination load, flexible interaction between seawater desalination and regional distribution network, and combined control of coastal multi-source multi-load storage system with seawater desalination load, are discussed in detail. Adoption of the flexible interaction between seawater desalination and regional distribution networks is beneficial for solving water resource problems, improving the ability to dissipate distributed renewable energy, balancing and increasing grid loads, improving the safety and economy of coastal power grids, and achieving coordinated and comprehensive application of power grids, renewable energy sources, and coastal loads.Ming Zhong Lu Jin Jiyu Xia Ling Cheng Peiyu Chen Rong Zeng 2019Global Energy Interconnection2019,2,4:3

9Water transport through subnanopores in the ultimate size limit: Mechanism from molecular dynamics显示文摘Ab initio and classical molecular dynamics simulations show that water can flow through graphdiyne—an experimentally fabricated graphene-like membrane with highly dense (2.4 × 10^18 pores/m^2), uniformly ordered, subnanometer pores (incircle diameter 0.57 nm and van der Waals area 0.06 nm^2). Water transports through subnanopores via a chemical-reaction-like activated process. The activated water flow can be precisely controlled through fine adjustment of working temperature and pressure. In contrast to a linear dependence on pressure for conventional membranes, here pressure directly modulates the activation energy, leading to a nonlinear water flow as a function of pressure. Consequently, high flux (1.6 L/Day/cm^2/MPa) with 100% salt rejection efficiency is achieved at reasonable temperatures and pressures, suggesting graphdiyne can serve as an excellent membrane for water desalination. We further show that to get through subnanopores water molecule must break redundant hydrogen bonds to form a two-hydrogen-bond transient structure. Our study unveils the principles and atomistic mechanism for water transport through pores in ultimate size limit, and offers new insights on water permeation through nanochannels, design of molecule sieving and nanofluidic manipulation.Jiyu Xu Chongqin Zhu Yifei Wang Hui Li Yongfeng Huang Yutian Shen Joseph S.

10Petrogenesis of Early Permian Intrusive Rocks from Southeastern Inner Mongolia, China: Constraints on the Tectonic Framework of the Southeastern Central Asian Orogenic Belt显示文摘The late Paleozoic tectonic framework of the southeastern Central Asian Orogenic Belt is key to restricting the accretion orogeny between the Siberia Craton and the North China Craton. To clarify the framework, petrogenesis of early Permian intrusive rocks from southeastern Inner Mongolia was studied. Zircon U-Pb dating for bojite and syenogranite from Ar-Horqin indicate that they were emplaced at 288–285 Ma. Geochemical data reveal that the bojite is highly magnesian and low-K to middle-K calc-alkaline, with E-MORB-type REE and IAB-like trace element patterns. The syenogranite is a middle-K calc-alkaline fractionated A-type granite and shows oceanic-arc-like trace element patterns, with depleted Sr-Nd-Hf isotopes,(~(87)Sr/~(86)Sr)I = 0.7032–0.7042, ε_(Nd)(t) = +4.0 to +6.6 and zircon ε_(Hf)(t) = +11.14 to +14.99. This suggests that the bojite was derived from lithospheric mantle metasomatized by subducted slab melt, while the syenogranite originated from very juvenile arc-related lower crust. Usng data from coeval magmatic rocks from Linxi-Ar-Horqin, the Ar-Horqin intra-oceanic arc was reconstructed, i.e., initial transition in 290–280 Ma and mature after 278 Ma. Combined with regional geological and geophysical materials in southeastern Inner Mongolia, an early Permian tectonic framework as ‘one narrow ocean basin of the PAO', ‘two continental marginal arcs on its northern and southern' and ‘one intra-oceanic arc in its southern' is proposed.QIAN Cheng LU Lu SHI Lu DU Jiyu WANG Yan YANG Xiaoping ZHANG Yujin 2022Acta Geologica Sinica(English Edition)2022,96,5:1

13Rapid fatty acids detection of vegetable oils by Raman spectroscopy based on competitive adaptive reweighted sampling coupled with support vector regression显示文摘Objectives:The composition and content of fatty acids are critical indicators of vegetable oil quality.To overcome the drawbacks of traditional detection methods,Raman spectroscopy was investigated for the fast determination of the fatty acids composition of oil.Materials and Methods:Rapeseed and soybean oil at different depths of the oil tank at different storage times were collected and an eighth-degree polynomial function was used to fit the Raman spectrum.Then,the multivariate scattering correction,standard normal variable transformation(SNV),and Savitzky–Golay convolution smoothing methods were compared.Results:Polynomial fitting combined with SNV was found to be the optimal pretreatment method.Characteristic wavelengths were selected by competitive adaptive reweighted sampling.For monounsaturated fatty acids(MUFAs),polyunsaturated fatty acids(PUFAs),and saturated fatty acids(SFAs),44,75,and 92 characteristic wavelengths of rapeseed oil,and 60,114,and 60 characteristic wavelengths of soybean oil were extracted.Support vector regression was used to establish the prediction model.The R^(2)values of the prediction results of MUFAs,PUFAs,and SFAs for rapeseed oil were 0.9670,0.9568,and 0.9553,and the root mean square error(RMSE)values were 0.0273,0.0326,and 0.0340,respectively.The R^(2)values of the prediction results of fatty acids for soybean oil were respectively 0.9414,0.9562,and 0.9422,and RMSE values were 0.0460,0.0378,and 0.0548,respectively.A good correlation coefficient and small RMSE value were obtained,indicating the results to be highly accurate and reliable.Conclusions:Raman spectroscopy,based on competitive adaptive reweighted sampling coupled with support vector regression,can rapidly and accurately analyze the fatty acid composition of vegetable oil.Linjiang Pang Hui Chen Liqing Yin Jiyu Cheng Jiande Jin Honghui Zhao Zhihao Liu Longlong Dong Huichun Yu Xinghua Lu 2022Food Quality and Safety2022,6,4:0
14Acute Toxicity of Oxyclozanide Suspension in Mice by Oral Administration显示文摘The safety of oxyclozanide suspension was preliminarily evaluated through acute toxicity test in mice. Administration dose,formal trial grouping and group interval were determined in pre-trial using incremental method. Formal test was performed using simplified karber's method. Changes in sign of mice after administration were observed; the mortality rate was statistically calculated,and the time of death was recorded; the median lethal dose( LD_(50)) and 95% confidence limit of oxyclozanide suspension were calculated. The results showed the LD_(50) of oxyclozanide suspension in mice by oral administration was 1. 679 g/kg,and the95% confidence interval was 1. 439-1. 947 g/kg. According to toxicity grading of chemicals,oxyclozanide suspension was low toxic substance.Zhang Jili Zhang Jiyu Si Hongfei Cheng Fusheng Zhou Xuzheng Li Bing 2016Animal Husbandry and Feed Science2016,8,6:0

16Dynamic Fracture Simulation of Functionally Graded Engineered Cementitious Composite Structures Based on Peridynamics显示文摘In this paper,a semi-discrete model based on peridynamics(PD)for engineered cementitious composites(ECCs)is applied to simulate the fracture behavior of functionally graded ECC(FGECC)beams.This is a new application of PD in ECC.Prior to simulating the crack behavior,the convergence of the PD model for ECC is discussed and the appropriate horizon size 5 and nonlocal ratio m are obtained,i.e.,S=1.6 mm and m=4.In addition,when the bond strain exceeds the elastic limit,a damage variable is introduced into the model,and the model is validated using a simple numerical algorithm.Finally,the dynamic fracture behavior of a two-dimensional FGECC beam under four-point bending is investigated,and the effect of the initial crack location on the fracture behavior is analyzed.Simulation results show that the initial crack location can affect the crack propagation pattern,thereby enabling one to understand the dynamic fracture behavior of ECC structures and guide the engineering practice.Zhanqi Cheng You Wu Liusheng Chu Jiyu Tang Chengfang Yuan Hu Feng 2022Acta Mechanica Solida Sinica2022,35,1:0
17The effect of kiwi berry(Actinidia arguta)on preventing and alleviating loperamide-induced constipation显示文摘This research aimed to study the preventive and relieving outcomes of kiwi berry on constipation.The administration of kiwi berries to mice resulted in a significant increase in body weight gain of 148.2%compared to mice that were constipated.The number of stools and the water content of stools both increased by 138.5%and 106.5%,respectively.The gastrointestinal transit rate increased by 45.3%,and the time it took for the first dark stool to form decreased by 57.5%.The levels of the excitability neurotransmitters were found to be higher in the group that had been given kiwi berries in comparison to the group that had been given loperamide.The opposite results were produced by vasoactive intestinal peptide(VIP)and aquaporin-3(AQP3).In addition,kiwi berry consumption may lessen epithelial cell apoptosis and promote colon health.All the results point to kiwi berries as an extremely promising food supplement for the prevention and relief of constipation in the future since they successfully prevent and alleviate constipation brought on by loperamide.Jiyue Zhang Dongnan Li Qilin Tian Yumeng Ding Hanqian Jiang Guang Xin Shunchang Cheng Siyi Tang Chenyu Jin Jinlong Tian Bin Li 2023Food Innovation and Advances2023,2,1:0
