  1. 31. Effects of commercial hatchery processing on behaviour and welfare of laying hens

    Författare :Louise Hedlund; Per Jensen; Charlotta Berg; Bas Rodenburg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Around the world, more than 76.7 million tons of eggs are consumed every year. To meet this demand, billions of laying hen chicks are produced under highly industrial circum-stances. These chicks are hatched in commercial hatcheries for laying hens in a presumably stressful environment, which might affect their welfare and production later in life. LÄS MER

  3. 32. Development of Functionalized Protein Materials

    Författare :Yusheng Yuan; Niclas Solin; Olle Inganäs; Qi Zhou; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Many proteins are available as side-streams from food production, and in some cases even from industrial waste-streams. This means that proteins are available in large scale and at a relatively low price. As protein are highly complex molecules it is interesting to try to use protein as starting materials in for applications in materials science. LÄS MER

  4. 33. Voltage sensor movements in shaker and HCN channels

    Författare :Roope Männikkö; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Voltage-gated ion channels are crucial for electrical signaling in living organisms. They are composed of four similar subunits with six transmembrane α-helices, S1-S6. Each subunit contains a voltage-sensing domain, S1-S4, and an ion-conducting pore domain, S5-S6. LÄS MER

  5. 34. The influence of clients on the social identities within the audit profession

    Sammanfattning : The overall purpose of the thesis is to explore the meaning of professionalism and independence for the individuals within the audit arena. Professionalism is defined as the occupational values that guide auditors’ professional behaviour, and how independence is understood is assumed to be influenced by the social groups the auditors identify with.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 1 Diabetes; NOD mouse; B cells; IgE; TACI; BAFF; immunologi; Immunology;

    Sammanfattning : The non-obese diabetic (NOD) mouse is widely used model Type 1 diabetes (T1D), a chronic inflammatory disease characterized by destruction of the insulin producing β cells in the islets of Langerhans by immune cells. The classical symptoms include increased glucose levels in urine and blood, frequent urination and enhanced thirst. LÄS MER
