    Sammanfattning : Hemicelluloses are a group of heterogeneous polysaccharides representing around 30 % of wood where the dominating types are xylans, glucomannans and xyloglucans. Hemicelluloses complex molecular structure makes it difficult to understand the relationship between structure and properties entirely, and their biological role is not yet fully verified. LÄS MER

  3. 2. How does the job applicants' ethnicity affect the selection process? : Norms, Preferred competencies and expected fit

    Författare :Sima Wolgast; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Discrimination; Ethnicity; Arab; systematic recruitment; Organizational norms; Person Environment fit; organizational psychology; intergroup relations; in-group and out-group; in-group favoritism; stereotypes; Social psychology; diskriminering; etnicitet; arab; systematiskt rekrytering; organisations normer; Person-miljö matchning; organisations psykologi; intergrupp relationer; in-grupp och ut-grupp; in-grupps favouritism; Stereotyper; social psykologi;

    Sammanfattning : The present thesis aimed to study different factors influencing recruiters when recruiting from an applicant pool with applicants from an ethnic ingroup and outgroup. Ethnicity was predicted to influence recruiters’ perception and behaviour in different phases during recruitment. LÄS MER

  4. 3. Temperature-dependent structure and function of group A streptococcal M proteins

    Författare :Tommy Cedervall; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; plasma protein; fibrinogen; temperature; hydrophobicity; coiled-coil; Ig-binding; M protein; group A streptococcus; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Temperature-dependent structure and function of group A streptococcal M proteins.This thesis describes the temperature-dependent structure of the members in the group A streptococcal M protein family. M proteins are cell-surface proteins that are important for the bacterial virulence and bind to a diverse set of human plasma proteins. LÄS MER

  5. 4. A Study of Parton Dynamics from Deep Inelastic Scattering Events Containing a Jet in the Forward Direction

    Författare :Martin Karlsson; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; DIS; ep scattering; H1; jets; forward jet; small-x; parton dynamics; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2002:Karlsson;

    Sammanfattning : The DIS ep-scattering parton dynamics at low-x is characterised by an initial state cascade in which the virtualities of the propagator gluons are expected to take any kinematically allowed value, in contrast to the leading log behaviour. These dynamics might be enhanced by selecting events in which an energetic jet is found in the forward angular region at HERA, 1. LÄS MER

  7. 5. Naphthoxylosides Investigations into glycosaminoglycan biosynthesis

    Författare :Mårten Jacobsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; proteoglycan; Organic chemistry; nucleophilic aromatic substitution; thioether; glycosaminoglycan; xylosides; naphthoxylosides;

    Sammanfattning : Glycosaminoglycans (GAGs) are members of a family of polysaccharide structures consisting mostly of repeating disaccharide units. Most GAGs are attached to specific serine residues in proteins to form proteoglycans (PGs). LÄS MER
