  1. 11. Surface Energy Exchange and Hydrology of a Poor Sphagnum Mire

    Författare :Erik Kellner; Harald Grip; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Sphagnum; Geovetenskap; myr; energibudget; ytresistans; vitmossa; hydrologiska modeller; TDR; Earth sciences; Geovetenskap; Hydrology; hydrologi;

    Sammanfattning : Mires surface energy and water budgets govern the conditions for climatic, hydrological, ecological and carbon balance processes. The components of the water and surface energy budgets were quantified over two growing seasons for an open boreal mire. LÄS MER

  3. 12. Coupled processes in seasonally frozen soils : Merging experiments and simulations

    Författare :Mousong Wu; Per-Erik Jansson; Bjorn Klove; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Frozen soil; Coupled transport; Energy balance; Uncertainties; Merged study; 冻土；水热盐运移；耦合关系；水热平衡；不确定性; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Soil freezing/thawing is of importance in the transport of water, heat and solute, with coupled effects. Due to complexity in soil freezing/thawing, uncertainty could be influential in both experimentation and simulation work in frozen soils. LÄS MER

  4. 13. Finite temperature properties of elements and alloy phases from first principles

    Författare :Hossein Ehteshami; Pavel A. Korzhavyi; Andrei V. Ruban; Tilmann Hickel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials Science and Engineering; Teknisk materialvetenskap; Physics; Fysik;

    Sammanfattning : First principles calculations are usually concerned with properties calculated at temperature 0 K. However, the industrially important materials are functioning at finite temperatures. LÄS MER

  5. 14. Thermal Capacity of Railway Wheels - Temperatures, residual stresses and fatigue damage with special focus on metro applications

    Författare :Shahab Teimourimanesh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway tread braking; finite element analysis; frictional heating; fatigue damage; metro trains; rig field experiments; railway wheels; stop braking; temperatures;

    Sammanfattning : Tread (block) braking is still one of the most common braking systems on railway vehicles.The action is carried out by pressing brake blocks against the tread of a wheel, which is also inrolling contact with the rail. LÄS MER

  7. 15. Plant Membrane Proteomics - using isolated membranes and proteins to compare and quantify subproteomes

    Författare :Katja Bernfur; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; quantification; proteomics; metabolic labeling; plasma membrane;

    Sammanfattning : Membrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. LÄS MER
