  1. 1. Iron in the Lena River basin, NE Russia : Insights from microscopy, spectroscopy and isotope analysis

    Författare :Catherine Hirst; Carl-Magnus Mörth; Per Andersson; Mats Erik Åström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; reactivity; isotopes; permafrost; river; Arctic; Marine Geology; maringeologi;

    Sammanfattning : Iron is an important mediator of biotic and abiotic processes on the Earth’s surface, being an electron acceptor in organic matter degradation, a surface for organic matter and trace element adsorption, and a required element for enzymatic processes during primary production. Yet, the role of iron as a mediator of carbon and trace element cycling in high latitude, permafrost-dominated regions remains poorly investigated. LÄS MER

    Sammanfattning : The use of nano- and micro-particulate carriers as delivery systems for oral vaccines has been under investigation for several decades. Surprisingly little is known of their uptake in the human intestine, despite the fact that substantial improvement is required to achieve adequate immune responses in man after oral administration.

    Sammanfattning : This thesis is about knowing in biology in higher education and research. The gene concept is used as an example of knowledge content that is common to both biological research and education. The purpose is to study how knowing about the gene is expressed in different forms of knowledge contexts at the university. LÄS MER
