10波罗的海河流养分运输模拟:一种大尺度途径显示文摘我们首次开发了一个集水区模型,对波罗的海流域内所有105个主要集水区的陆地-海洋养分通量同时进行了模拟。对所有这些主要集水区进行一致模拟的方法,即水通量(水文模拟)和负荷功能(排放数据)的一致处理,将促进波罗的海差别巨大的子流域之间河流养分运输的比较。河流排放的热点,如维斯瓦河、奥得河、道加瓦河或丹麦海岸,可以很容易地被展示;并且这些热点及北部集水区中相对未被干扰的河流之间的比较可为决策者指明:1)要改善波罗的海环境状况,在哪里采取补救措施最有效。2)河流养分负荷可能削减的百分比是多少。验证期内实测通量与模拟通量之间的相对差异通常很小。监测水体流量和养分通量的累积偏差(即相对偏差)[∑(模拟-实测)/∑实测×100(%)]总计为径流+8.2%,可溶性无机氮-2.4%,总氮+5.1%,可溶性无机磷+13%,总磷+19%。并且,该模型认为,现存的污染负荷汇编资料中低估了总磷点源,因为在市政府的排放负荷计算中存在着矛盾。Carl-Magnus Mrth Christoph Humborg Hanna Eriksson sa Danielsson Miguel Rodriguez Medina Stefan Lfgren Dennis P.Swaney Lars Rahm 王胜 2007AMBIO-人类环境杂志2007,36,2:1

15Magnetotactic bacteria from the human gut microbiome associated with orientation and navigation regions of the brain显示文摘Magnetotactic bacteria(MTB),ubiquitous in soil and fresh and saltwater sources have been identified in the microbiome of humans and many animals.MTB endogenously produce magnetic nanocrystals enabling them to orient and navigate along geomagnetic fields.Similar magnetite deposits have been found throughout the tissues of the human brain,including brain regions associated with orientation such as the cerebellum and hippocampus,the origins of which remain unknown.Speculation over the role and source of MTB in humans,as well as any association with the brain,remain unanswered.We performed a metagenomic analysis of the gut microbiome of 34 healthy females as well as grey matter volume analysis in magnetite-rich brain regions associated with orientation and navigation with the goal of identifying specific MTB that could be associated with brain structure in orientation and navigation regions.We identified seven MTB in the human gut microbiome:Magnetococcus marinus,Magnetospira sp.QH-2,Magnetospirillum magneticum,Magnetospirillum sp.ME-1,Magnetospirillum sp.XM-1,Magnetospirillum gryphiswaldense,and Desulfovibrio magneticus.Our preliminary results show significant negative associations between multiple MTB with bilateral flocculonodular lobes of the cerebellum and hippocampus(adjusted for total intracranial volume,uncorrected P<0.05).These findings indicate that MTB in the gut are associated with grey matter volume in magnetite-rich brain regions related to orientation and navigation.These preliminary findings support MTB as a potential biogenic source for brain magnetite in humans.Further studies will be necessary to validate and elucidate the relationship between these bacteria,magnetite concentrations,and brain function.Rozalyn A.SIMON Purnika Damindi RANASINGHE Nawroz BARAZANJI Malin Bergman JUNGESTRÖM Jie XU Olga BEDNARSKA Lena SERRANDER Maria ENGSTRÖM Dennis A.BAZYLINSKI Åsa V.KEITA Susanna WALTER 2021Journal of Oceanology and Limnology2021,39,6:0
16Ion emission from warm dense matter produced by irradiation with a soft x-ray free-electron laser显示文摘We report on an experiment performed at the FLASH2 free-electron laser(FEL)aimed at producing warm dense matter via soft x-ray isochoric heating.In the experiment,we focus on study of the ions emitted during the soft x-ray ablation process using time-of-flight electron multipliers and a shifted Maxwell–Boltzmann velocity distribution model.We find that most emitted ions are thermal,but that some impurities chemisorbed on the target surface,such as protons,are accelerated by the electrostatic field created in the plasma by escaped electrons.The morphology of the complex crater structure indicates the presence of several ion groups with varying temperatures.We find that the ion sound velocity is controlled by the ion temperature and show how the ion yield depends on the FEL radiation attenuation length in different materials.Josef Krása Tomás Burian Vera Hájková Jaromír Chalupský Šimon Jelínek Katerina Frantálová Michal Krupka Zuzana Kuglerová Sushil Kumar Singh Vojtech Vozda Ludek Vysín MichalŠmíd Pablo Perez-Martin Marion Kühlman Juan Pintor Jakub Cikhardt Matthias Dreimann Dennis Eckermann Felix Rosenthal Sam M.Vinko Alessandro Forte Thomas Gawne Thomas Campbell Shenyuan Ren YuanFeng Shi Trevor Hutchinson Oliver Humphries Thomas Preston Mikako Makita Motoaki Nakatsutsumi Xiayun Pan Alexander Köhler Marion Harmand Sven Toleikis Katerina Falk Libor Juha 2024Matter and Radiation at Extremes2024,9,1:0
