    Abstract : The human glucose transporter GLUT1 is abundant in red blood cells, the blood-brain barrier and epithelial cells, where it mediates the transport of the energy metabolite, glucose. In the present work some properties of GLUT1, including affinity binding of both substrates and inhibitors, transport rates as well as permeabilities of aromatic amino acids and drug-membrane interactions were analyzed by chromatographic methods.

  3. 18. Development of a Solvent Extraction Process for Group Actinide Recovery from Used Nuclear Fuel

    University dissertation from Chalmers University of Technology

    Author : Emma Aneheim; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solvent Extraction; Partitioning; GANEX; BTBP; TBP; Fission Products;

    Abstract : When uranium is used as fuel in nuclear reactors it both undergoes neutron induced fission as well as neutron capture. Through successive neutron capture and beta decay transuranic elements such as neptunium, plutonium, americium and curium are produced in substantial amounts. READ MORE

    Abstract : Partitioning and transmutation of spent nuclear fuel enables a decrease in the long term radiotoxicity and volume of the waste to be disposed. By transforming the long-lived nuclides into shorter-lived or even stable ones, the time required for a final repository to be regarded safe for the environment can decrease from 100,000 years to less than 1,000 years.
