  1. 11. Inductively Coupled Plasma Spectrometry for Speciation Analysis : Development and Applications

    Författare :Niklas Forsgard; Jean Pettersson; Marit Andersson; Jonas Bergquist; Walter Lund; Uppsala universitet; []
    Nyckelord :Analytical chemistry; Speciation analysis; Atomic emission spectrometry AES ; Mass spectrometry MS ; Inductively coupled plasma ICP ; Liquid Chromatography LC ; on-line sample pre-treatment; Organic phosphour; Siderophores; Slurry nebulization; matrix effects; Analytisk kemi;

    Sammanfattning : In analytical chemistry the main goal is normally to determine the identity and/or concentration of one or more species in a sample. The samples analyzed are often natural samples, containing numerous different species in a complex matrix and the choice of technique for multi-elemental detection is in general inductively coupled plasma spectrometry.

  3. 12. Regret and Risk Optimal Design in Control

    Författare :Matias Müller; Cristian R. Rojas; Anders Rantzer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Engineering sciences deal with the problem of optimal design in the face of uncertainty. In particular, control engineering is concerned about designing policies/laws/algorithms that sequentially take decisions given unreliable data.This thesis addresses two particular instances of optimal sequential decision making for two different problems.

  4. 13. Atomic Scale Characterization of III-V Nanowire Surfaces

    Författare :Johan Knutsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :III–V semiconductor materials; nanowire; surface; scanning tunneling microscopy; wurtzite; zinc blende; scanning tunneling spectroscopy; Fysicumarkivet A:2017:Knutsson;

    Sammanfattning : This dissertation focus on the atomic-scale characterization of the surface properties and electronic structure of III–V semiconductor nanowires (NWs). Since the early 2000s, the fabrication and characterization of III–V NWs has been a very significant topic within material science due to their potential for applications in lighting, energy harvesting, and electronics.

  5. 14. Assessment of Computational Methods for Ligand Binding

    Författare :Paulius Mikulskis; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; binding affinities; MM GBSA; MM PBSA; LIE; FEP; TI; BAR; protein-ligand complexes; drug design;

    Sammanfattning : Most drugs act on biomacromolecules. The Cost of developing new drugs is very high. A method to accurately predict binding affinities would be very useful. LÄS MER

  7. 15. Common medications in the risk and prognosis of lymphoid neoplasms and epidemiology of primary CNS lymphoma

    Författare :Elsa Brånvall; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Lymphoid neoplasms are malignancies arising from the lymphocyte, and include lymphoma subtypes, chronic lymphocytic leukemia (CLL) and multiple myeloma (MM). It is a heterogenous group of diseases, with different molecular pathogenesis, clinical characteristics, treatments and outcome. LÄS MER
