1挪威湖泊沉积物中的微量元素污染显示文摘我们用挪威210个湖泊表层沉积物和工业化前沉积物中锑、汞、铋、镉、钼、砷、钴、镍、铬、铜、钒、铅和锌的浓度,研究了它们的近代大气沉积物。水表层沉积物中锑、汞、铋、镉、砷、铅的浓度比工业化前的沉积物高得多。差异随纬度和海拔的增高而缩小。对表层沉积物微量元素和主要成分(有机物、硅、铝、铁和锰)的多变量分析表明:锑、汞、铋、砷和铅组成一组,它们与有机物紧密相关。镍、铬和铜与无机沉积物部分(硅、铝)有微弱的相关而形成第二组。锌和镉与有机物微弱相关构成第三组。钴和锰相关,而钼和钒对其他微量元素和主要成分没有表现出明显的共变性。Sigurd Rognerud Eirik Fjeld 郑萧 2001AMBIO-人类环境杂志2001,30,1:15
2北欧湖泊的重金属调查:浓度、地理模式及与临界界限的关系显示文摘1995年秋天,北欧各国同时对本国的湖泊进行了调查,包括俄罗斯西北的科拉半岛。在大约3000个湖泊中,被调查的11种金属(铅、镉、砷、锌、铜、镍、钴、铁、锰、铬、钒)一般浓度较低,并具有明确的地理模式。对于铅、镉、锌和一定程度上钴的分布,远程迁移的空气污染带来的直接和间接影响是最重要的因素。湖中总有机碳(TOC)浓度对于铁和锰,并在一定程度上对于砷、铬和钒是重要的。对于铜和镍,基岩地质概况是最重要的控制因素,但在科拉半岛很多冶炼厂周围地区是个例外,在那里由于当地空气传播的污染,湖泊中铜和镍的浓度很高。基岩和地表的地质概况对于控制砷、钴、铬和钒的浓度也是重要的因素。调查结果表明在北欧国家湖泊中重金属污染在区域尺度上是一个较轻微的生态问题。Brit Lisa Skjelkvle Tom Andersen Eirik Fjeld Jaakko Mannio Anders Wilander Kjell Johansson Jens Peder Jensen Tatyana Moiseenko 孙学飞 2001AMBIO-人类环境杂志2001,30,1:11
3Brain changes in diabetes mellitus patients withgastrointestinal symptoms显示文摘Diabetes mellitus is a common disease and its prevalence is increasing worldwide. In various studies up to 30%-70% of patients present dysfunction and complications related to the gut. To date several clinical studies have demonstrated that autonomic nervous system neuropathy and generalized neuropathy of the central nervous system(CNS) may play a major role. This systematic review provides an overview of the neurodegenerative changes that occur as a consequence of diabetes with a focus on the CNS changes and gastrointestinal(GI) dysfunction. Animal models where diabetes was induced experimentally support that the disease induces changes in CNS. Recent investigations with electroencephalography and functional brain imaging in patients with diabetes confirm these structural and functional brain changes. Encephalographic studies demonstrated that altered insular processing of sensory stimuli seems to be a key player in symptom generation. In fact one study indicated that the more GI symptoms the patients experienced, the deeper the insular electrical source was located. The electroencephalography was often used in combination with quantitative sensory testingmainly showing hyposensitivity to stimulation of GI organs. Imaging studies on patients with diabetes and GI symptoms mainly showed microstructural changes,especially in brain areas involved in visceral sensory processing. As the electrophysiological and imaging changes were associated with GI and autonomic symptoms they may represent a future therapeutic target for treating diabetics either pharmacologically or with neuromodulation.Anne M Drewes Eirik Søfteland Georg Dimcevski Adam D Farmer Christina Brock Jens B Frøkjær Klaus Krogh Asbjørn M Drewes 2016World Journal of Diabetes2016,7,2:4
4一种新螺杆挤压法从6063铝合金和Mg混合颗粒制备Al/Mg复合材料(英文)显示文摘采用一种新的螺杆挤压法以AA6063合金和工业纯Mg混合颗粒为原料制备Al/Mg双金属复合材料。加入铝合金中的镁合量最高可达到12.5%(质量分数)。所制备复合材料由细小晶粒组织组成。其显微组织中除有原料中的物相外,还观察到由γ-Mg17Al12包围的岛状Al2Mg3金属间合物。复合材料的强度随Mg含量的增加逐渐增高。含Mg为10%复合材料的极限抗拉强度最高,超过350 MPa。断裂表面分析结果表明,增加Mg含量导致材料发生较严重的脆性断裂及断裂机制的较小变化。因此,应对挤压工艺条件进行进一步优化。Kristian Gr tta SKORPEN Eirik MAUL Oddvin REISO Hans J rgen ROVEN 2014Transactions of Nonferrous Metals Society of China2014,24,12:4
5Minamata Convention on Mercury: Chinese progress and perspectives显示文摘Mercury(Hg)is a global threat to human and environmental health[1].To address this global issue,the Minamata Convention on Mercury(MC)was agreed upon by 128 countries on 19January 2013.China officially ratified the MC in August 2016.As the largest emit-Yan Lin Shuxiao Wang Eirik Hovland Steindal Hua Zhang Huan Zhong Yindong Tong Zuguang Wang Hans Fredrik Veiteberg Braaten Qingru Wu ThorjФrn Larssen 2017National Science Review2017,4,5:3
6挪威海底公路隧道经验——施工、运行、 费用和维护(英文)显示文摘根据2002年关于挪威海底公路隧道的一论文集(挪威公路管理局公路技术部编辑,题目为'论文集98——挪威海底公路隧道',将详细阐述挪威海底隧道的施工建造等经验。挪威第一条海底公路隧道是在1983年通车的,随后建成了另外24条海底公路隧道,至今共有25条海底公路隧道建成通车,总长度达100km。几条新的海底公路隧道目前正在建设中,还有几条则在规划当中,其中最长将达24km。大多数条海底公路隧道是单洞双线,但是当坡度大于6%时,有些隧道就增加一条线。海底公路隧道都位于沿海岸线的干线公路上,以代替原有的繁忙的轮渡,并建立大陆与当地之间的无轮渡连接。据此,主要介绍这些隧道工程中得到的经验,总的来说,海底公路隧道的建设费用逐渐降低,但是各工程间差异很大,各个隧道的运行和维护的费用也相差悬殊,再投资和设备花费也特别高。经验表明,随着渗水量逐年减少,因而抽出渗透水的要求也降低了。介绍了1996年前17条海底隧道中发生的事故和火灾,对19起造成人身伤害的事故进行了分析。其事故发生率极低,只有0.09(每年每一百万车辆每公里发生的事故次数),最高的事发率是在陡坡的年平均日通车量(AADT)低于1500的隧道中。挪威海底隧道中只发生过3起火灾事故,低于交通事故率10%,而这项研究只包括了17条隧道中发生的19起事故。HENNING Jan Eirik MELBY Karl фVSTEDAL Erik AMUNDSEN Finn H RANES Guro 2007岩石力学与工程学报2007,26,11:2
