  1. 1. Modelling of Traffic Performance for Swedish Roads and Motorways

    Författare :Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural highway; Intersection; Capacity; Critical gap; Flare; Micro simulation; Motorway; Ramp; Weaving; Merging; Queue; Delay; Over-saturated; Time-space; Roadwork zone; variable speed limit; harmonization; Transportvetenskap; Transport Science;

    Sammanfattning : This thesis consists of five scientific articles oriented towards capacity. Managing capacity constraints with associated delays is a big issue at new design as well as at trimming existing traffic facilities. LÄS MER

    Sammanfattning : Driving patterns, i.e. the speed and acceleration profiles of vehicles affect exhaust emission and fuel consumption considerably. LÄS MER

  4. 3. Molecular mechanisms of nerve-tumor interactions : the intersection of cancer and neurodevelopment

    Författare :Luz Maria Gonzalez-Castrillon; Sara I Wilson; Daniel Öhlund; Nisha D’Silva; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Perineural invasion; cancer; PDAC; axonogenesis; neurodevelopment; spinal cord; axon guidance; bioinformatics.; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Sammanfattning : A wide range of cancers throughout the body are characterized by high nerve density and invasion of cancer cells within the nerves, a process called perineural invasion (PNI). Work in the field has shown that blocking nerves in organs with tumors leads to improved disease outcomes suggesting that finding ways to block tumor nerves could lead to new treatment approaches.

  5. 4. Computational chemistry studies of UV induced processes in human skin

    Författare :Jonas Danielsson; Aatto Laaksonen; Villy Sundström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photochemistry; Theoretical chemistry; Density functional theory; UV effects; TD-DFT; enzyme catalysis; DNA damage; Molecular dynamics; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : This thesis presents and uses the techniques of computational chemistry to explore two different processes induced in human skin by ultraviolet light. The first is the transformation of urocanic acid into a immunosuppressing agent, and the other is the enzymatic action of the 8-oxoguanine glycosylase enzyme. LÄS MER

  7. 5. On surface structure characterization and application on additive manufacturing

    Författare :Olena Flys; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface texture parameters.; fused deposition modelling; power spectral density; coherence scanning interferometer; selective laser melting; Surface characterization;

    Sammanfattning : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. The fast-growing industry of additive manufacturing admits the surface roughness as one of the main challenges. LÄS MER
