| 2 | Genetic diversity analysis of Hepatacodium miconioides at different altitude in Tiantai Mountain,Zhejiang Province,China and its relationship with environmental factors显示文摘The genetic diversity within and among populations of Hepatacodium miconioides collected at three different altitudes in Tiantai Mountain,Zhejiang Province and its relationships to environmental factors were analyzed by random amplified polymorphic DNA(RAPD)technique.Amplification using 12 random primers of 60 plants and 122 repetitive loci were produced.The percentage of polymorphic loci of three populations ranged from 18.85%to 23.77%with an average of 21.86%,indicating the relatively low genetic diversity of H.miconioides.The average Shannon index of phenotypic diversity(0.1329)and Nei index(0.0925)within populations were relatively low.A distinct genetic differentiation existed among populations of H.miconioides in spite of the relatively small geographical distribution.The average genetic diversity within populations of H.miconioides accounted for 33.58%of the total genetic diversity while the genetic diversity among populations accounted for 66.42%as estimated by the Shannon index of phenotypic diversity,The genetic differentiation among populations of H.miconioides was 0.6546,as estimated by Nei index.The gene flow estimated from GST was only 0.2656 and it indicated that gene flow among populations of H.miconioides was relatively low.The mean value of the genetic identity among populations of H.miconioides was 0.7126 and the average of genetic distance of H.miconioides was 0.3412.The genetic identity between populations at the elevation of 990 m and at the elevation of 780 m was the highest.The genetic identity between population at the elevation 500 m and other two populations was relatively low.The correlation analysis showed that the genetic diversity within populations was significantly related with the soil total nitrogen. | Jin Zexin Li Junmin | 2006 | Frontiers in Biology2006，1，2： | 0 |
| 3 | Study on the Toxicity of Acetochlor to Loaches显示文摘[Objectives] This study was conducted to investigate the toxic effect of acetochlor in loaches. [Methods]Loaches were put into the acetochlor solution with concentrations of 0,0. 062 5,0. 125,0. 25,0. 5 and 1 μl/L,respectively. The effects on dismutase( SOD),peroxidase( POD),catalase( CAT) and glutathione( GSH) activity and malondialdehyde( MDA) content in the liver of loaches were analyzed after 12,24,48 and 72 h of exposure. [Results] The activity of SOD,POD,CAT and GSH increased with the stress time and concentration,reached their maximums at 48 h after acetochlor treatment,and then decreased.However,MDA content increased with the stress time and concentration. [Conclusions] Acetochlor had obvious oxidative stress on loaches,and the activity of SOD,POD,CAT and GSH showed an obvious induction-inhibition effect with the increase of acetochlor concentration and the extension of stress time. | Yan WANG Peng DONG Pei XU Yuxiang LIN Zexin CHEN Yihong HU Chenzhong JIN Yiding WANG Kaifa GUO Qianxia ZHU | 2020 | Agricultural Biotechnology2020，9，3： | 0 |
| 4 | Quantifying Solid Solution Strengthening in Nickel-Based Superalloys via High-Throughput Experiment and Machine Learning显示文摘Solid solution strengthening(SSS)is one of the main contributions to the desired tensile properties of nickel-based superalloys for turbine blades and disks.The value of SSS can be calculated by using Fleischer’s and Labusch’s theories,while the model parameters are incorporated without fitting to experimental data of complex alloys.In thiswork,four diffusionmultiples consisting of multicomponent alloys and pure Niare prepared and characterized.The composition and microhardness of singleγphase regions in samples are used to quantify the SSS.Then,Fleischer’s and Labusch’s theories are examined based on high-throughput experiments,respectively.The fitted solid solution coefficients are obtained based on Labusch’s theory and experimental data,indicating higher accuracy.Furthermore,six machine learning algorithms are established,providing a more accurate prediction compared with traditional physical models and fitted physical models.The results show that the coupling of highthroughput experiments and machine learning has great potential in the field of performance prediction and alloy design. | Zihang Li Zexin Wang Zi Wang Zijun Qin Feng Liu Liming Tan Xiaochao Jin Xueling Fan Lan Huang | 2023 | Computer Modeling in Engineering & Sciences2023，，5： | 0 |
