  1. 1. Ion recombination in liquid ionization chambers development of an experimental method to quantify general recombination

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Jonas Andersson; Umeå universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General recombination; initial recombination; liquid ionization chamber; radiation dosimetry; radiofysik; radiofysik;

    Sammanfattning : An experimental method (the two-dose-rate method) for the correction of general recombination losses in liquid ionization chambers has been developed and employed in experiments with different liquids and radiation qualities. The method is based on a disassociation of initial and general recombination, since an ionized liquid is simultaneously affected by both of these processes. LÄS MER

  2. 2. Theoretical studies of chemical dynamics on excited states, driven by non-adiabatic effects Charge recombination reactions

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Sifiso Musa Nkambule; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mutual neutralization; Dissociative recombination; electronic structure; non-adiabatic; Theoretical Physics; teoretisk fysik;

    Sammanfattning : This thesis is based on theoretical studies of molecular collisions occurring at relatively low to intermediate collision energies. The collisions are called dissociative recombination (DR) and mutual neutralization (MN). LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; recombination; biased gene conversion; CpG island; copy number variation; substitutions; methylation; Bioinformatik; Bioinformatics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Molekylär genetik; Molecular Genetics;

    Sammanfattning : Understanding the mechanism of recombination has important implications for genome evolution and genomic variability. The work presented in this thesis studies the properties of recombination by investigating the effects it has on genome evolution in humans and dogs. LÄS MER

  4. 4. Chromosome synapsis and recombination in yeast meiosis

    Detta är en avhandling från Stockholm : Institutionen för molekylärbiologi och funktionsgenomik

    Författare :Hasanuzzaman Bhuiyan; Stockholms universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; meiosis; recombination; synapsis; yeast; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi;

    Sammanfattning : Meiosis is a cell division process that produces haploid gametes from diploid cells. Several important meiotic events take place during prophase of meiosis I, most important being homologous chromosome pairing, meiotic recombination and formation of the synaptonemal complex (SC).

  5. 5. Site-Specific Recombination : Integrases, Accessory Factors and DNA Targets of P2-like Coliphages

    Detta är en avhandling från Stockholm : Department of Genetics, Microbiology and Toxicology, Stockholm University

    Författare :Lina Sylwan; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Cell and molecular biology Genetics; NATURVETENSKAP Biologi Cell- och molekylärbiologi Genetik; Molecular Genetics; molekylärgenetik;

    Sammanfattning : The temperate coliphage P2 and its family members integrate their genomes into the host Escherichia coli chromosome by a site-specific recombination mechanism to form lysogeny. Integration takes place between the complex phage attP site and the simple bacterial attB site and is catalyzed by the phage encoded integrase (Int). LÄS MER
