  1. 1. Weak Atomic Interactions

    Författare :Peter Schef; Sven Mannervik; Juliet C. Pickering; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metastable states; forbidden transitions; laser probing; hyperfine structure; LRDR; Atomic physics; Atomfysik;

    Sammanfattning : An atom or ion can change quantum state, usually through emission or absorption of a photon. The photon has the same energy as the energy difference between the states of the transition. The states, or energy levels, of an atom are quantized and light emitted, or absorbed, from the atom is therefore of specific wavelengths, giving spectral lines. LÄS MER

  3. 2. Colour Reconnection and Weak Showers

    Författare :Jesper Roy Christiansen; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Merging; Weak interactions; Parton Showers; Event generators; hadron collisions; Colour Reconnection; Fragmentation; Fysicumarkivet A:2015:Christiansen;

    Sammanfattning : This thesis consider the improvement of the simulation tools used to describe high energy particle collisions. These simulation programs are normally referred to as event generators. LÄS MER

  4. 3. Characterisation of weak and null phenotypes in the KEL and JK blood group systems

    Författare :Elisabet Sjöberg Wester; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; null; SNP; Kidd; JK; Blood group; Kell; KEL; weak;

    Sammanfattning : The focus of this thesis is on KEL and JK, two clinically important blood group systems, and the investigations of blood samples with aberrant antigen expression as in null and weak phenotypes, or with a phenotype that does not correspond to genotype. With the increasing use of DNA assays based on single nucleotide polymorphisms for blood group prediction, it is important to characterize the blood-groupencoding genes. LÄS MER

  5. 4. Insights into weak affinity antibody-antigen interactionsStudies using affinity chromatography and optical biosensor

    Författare :Magnus Strandh; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioteknik; Biotechnology; immunosensor; biosensor; weak affinity chromatography; cross-reactivity; antibody-antigen interaction; weak affinity; biomolecular recognition; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : Molecular recognition and interaction is fundamental for the function of biological systems. The properties of the interacting biomolecules dictate the type of forces involved and the strength and dynamics of the interaction. Many interactions are very strong whereas others exhibit weak affinity. LÄS MER
