  1. 1. Geometallurgy of a complex ore : Lappberget Zn-Pb-Ag-(Cu-Au) deposit, Garpenberg mine, Sweden

    Författare :Glacialle Tiu; Christina Wanhainen; Yousef Ghorbani; Nils Jansson; Jens Gutzmer; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ore Geology; Malmgeologi;

    Sammanfattning : Complex ores, in this instance, a polymetallic base metal ore with additional precious and penalty elements, pose particularly tough challenges for successful production forecasts. Plant performance and recoveries for complex ores are more difficult to predict due to the larger number of variables that must be considered, tracked, and characterized during the multi-stage separation process.

  3. 2. Abdominal Aortic Aneurysm : Experience from a Screening Study in Northern Sweden

    Författare :Anders Wanhainen; Martin Björck; Jesper Swedenborg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; abdominal aortic aneurysm; definition; prevalence; ultrasonography; computed tomography; variability; quality of life; SF-36; risk factor; cholesterol; smoking; CRP; heredity; atherosclerosis; screening; cost-effectiveness; cost-utility; Kirurgi; Surgery; Kirurgi;

    Sammanfattning : Abdominal aortic aneurysm (AAA) is a common problem with life-threatening consequences and was suspected to be a serious health problem in Norsjö, a municipality in northern Sweden. A screening study was undertaken to investigate the prevalence, risk factors associated with AAA and the effect of screening on quality of life (QoL). LÄS MER

  4. 3. On the origin and evolution of the palaeoproterozoic Aitik Cu-Au-Ag deposit, northern Sweden : a porphyry copper-gold ore, modified by multistage metamorphic-deformational, magmatic-hydrothermal, and IOCG-mineralizing events

    Författare :Christina Wanhainen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The Aitik Cu-Au-Ag mine in the Gällivare area in northern Sweden is the biggest open pit operation in northern Europe and one of Europe’s largest metal producers. The open pit is almost 3 km long, 930 m wide and 345 m deep. Approximately 424 million tonnes of ore averaging 0.4% Cu, 0. LÄS MER

  5. 4. Aspects of subaneurysmal aortas in a screening setting

    Författare :Knut Thorbjørnsen; Anders Wanhainen; Sverker Svensjö; Khatereh Djavani Gidlund; Håkan Pärsson; Uppsala universitet; []
    Nyckelord :Abdominal aortic aneurysm; subaneurysmal aorta; screening; health related quality of life; health utility; quality adjusted life years; Kirurgi; Surgery;

    Sammanfattning : With the introduction of screening programmes for abdominal aortic aneurysm (AAA) more individuals are being identified with a subaneurymal aorta (SAA; diameter 25-29mm). More recent data indicate that these aortas may not be as harmless as previously thought, but there is, however, no general agreement on how SAA should be managed. LÄS MER

  7. 5. Magmatic and hydrothermal processes in relation to the formation of the Aitik Cu-Au deposit, Northern Sweden

    Författare :Christina Wanhainen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : Aitik is a disseminated Cu-Au deposit with an annual production of 18 million metric tons of ore containing 0.38 percent copper and 0.22 parts per million gold. It is situated in northern Sweden in 1. LÄS MER
