| 1 | Assessment of heavy metal contamination in the surficial sediments from the lower Meghna River estuary, Noakhali coast, Bangladesh显示文摘Sediment samples were collected from ten selected sites of the lower Meghna River estuary,and six heavy metals were analyzed with Atomic Absorption Spectrophotometry(AAS)to assess the contamination level and the metals’association with sediment grain size.The current results revealed that the mean concentrations of the studied metals were ranked in descending order of iron(Fe)(1.29×103 mg/kg)>zinc(Zn)(42.41 mg/kg)>lead(Pb)(12.48 mg/kg)>chromium(Cr)(10.59 mg/kg)>copper(Cu)(6.22 mg/kg)>cadmium(Cd)(0.28 mg/kg).The geo-accumulation,contamination,and pollution load indexes suggested that the lower Meghna river estuary was not contaminated by Fe,Zn,Pb,Cr,and Cu.The mean size of the sediment ranged from 28.92 to 126.2 mm,and the Pearson correlation coefficient showed a significant association between Fe and Pb(coefficient of determination,r2=0.836;p<0.05),and no significant correlation was found between individual metals and grain size,indicating no or low influence on the metals distribution. | Mohammad Abdul Momin Siddique Mahfuzur Rahman Shahriar MdArifur Rahman MdRubel Hassan Zeenath Fardous Muhammed Alamgir Zaman Chowdhury Mohammad Belal Hossain | 2021 | International Journal of Sediment Research2021，36，3： | 2 |
| 2 | 基于K-核塌缩序列的社会化资源推荐中核心用户发现研究显示文摘【目的】通过对社交网站平台用户行为的分析,发现社会化小众群体中的核心用户,为社会化资源推荐服务提供参考。【方法】收集豆瓣读书用户的1 208个标签,对排名前100位的标签建立标签共现矩阵,分析用户的K-核网络结构,研究用户的K-核塌缩序列的波动情况。【结果】与度数中心度、最小K-核深度值等方法相比,基于K-核塌缩序列方法发现了新的社会化小众群体中的核心用户。【局限】样本数据规模较小且局限于某领域,排序问题不能得到很好的解决,需要进一步改进K-核分析方法。【结论】本研究有利于社交网站平台的管理者制定或改进新的资源推荐策略,从而促进社交网站平台更好地发展。 | 武慧娟 Jia Tina Du 孙鸿飞 Jannatul Fardous | 2016 | 现代图书情报技术2016，，9： | 2 |
