    Sammanfattning : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. LÄS MER

  3. 22. Recognition and Separation of Hemoglobin Variants via Molecularly Imprinted Polymers

    Författare :Ka Zhang; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hemoglobin; molecularly imprinted polymers; haptoglobin; protein purification; chromatography glyceraldehyde 3-phosphate dehydrogenase; Pickering emulsion;

    Sammanfattning : Hemoglobin (Hb) is the predominant protein in red blood cells with allosteric regulation mechanisms for delivering oxygen between the lungs and tissues. After the 1980s, concentrated research on modified Hb emerged because of the necessity for the development of a blood substitute (oxygen carrier). LÄS MER

  4. 23. Analytical developments and applications of ambient mass spectrometry imaging : Visualizing challenging analytes and understanding chemical mechanisms of ischemic stroke

    Författare :Leonidas Mavroudakis; Ingela Lanekoff; Daniel Globisch; Malcolm Clench; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry imaging; ischemic stroke; mass spectrometry; isomers; spatial metabolomics; host-guest; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : Bioanalytical methods that provide spatial information on molecular distributions are important for deep understanding of chemical mechanisms in health and disease. For instance, the localized action of drugs and metabolites can provide valuable information on metabolism in specific cellular regions, which would not be possible with bulk analysis. LÄS MER

  5. 24. Microfluidic Cell and Particle Sorting using Deterministic Lateral Displacement
