  1. 1. NMR studies of DNA structure and counterion behaviour

    Författare :Lorens van Dam; Gary Drobny; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : DNA is a polymer of nucleotides, each nucleotide consisting of a negatively charged phosphate group, a ribose sugar unit, and a purine or pyrimidine base. The secondary structure of DNA is commonly a double-helix with Watson-Crick paired bases. Several secondary structures, all with these features, are observed for DNA. LÄS MER

  3. 2. Visualization of Protein Activity Status in situ Using Proximity Ligation Assays

    Sammanfattning : In 2001 the human proteome organization (HUPO) was created with the ambition to identify and characterize all proteins encoded in the human genome according to several criteria; their expression levels in different tissues and under different conditions; the sub-cellular localization; post-translational modifications; interactions, and if possible also the relationship between their structure and function.When the knowledge of different proteins and their potential interactions increases, so does the need for methods able to unravel the nature of molecular processes in cells and organized tissues, and ultimately for clinical use in samples obtained from patients.

  4. 3. Sedimentological and Hydrological Investigation of Mosul Dam Reservoir

    Författare :Issa E Issa; Ian Foster; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area-storage capacity curves; Area reduction method; Bathymetric survey; Losing storage capacity; Mosul dam; Reservoir bottom morphology; Reservoir sedimentation; Sediment trap efficiency; Useful life of dam; Soil Mechanics; Geoteknik;

    Sammanfattning : Reservoir sedimentation is the main problem that directly affects the performance of dams due to the reduction in the storage capacity of their reservoirs. Monitoring the storage capacity of reservoirs is an important issue for the planners, designers and operators of the dams. LÄS MER

  5. 4. Rock grouting design: Rheological aspects and radial flow visualizations with ultrasound

    Författare :John Shamu; Stefan Larsson; Ulf Håkansson; Liangchao Zou; Chadi El Mohtar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement grouts; grouting; yield stress fluid YSF ; thixotropy; critical shear rate; radial flow; wall slip; Bingham model; Cementbaserade injekteringsmedels; injektering; icke-Newtonska vätskors; tixotropi; kritisk deformationshastigheten; radiella strömning; glidning; Bingham modell; Jord- och bergmekanik; Soil and Rock Mechanics;

    Sammanfattning : The rheological properties of cement-based grouts play a crucial role indetermining the final spread in grouted rock formations. In rheological terms,cement grouts are known to be complex time-dependent yield stress fluids,but their steady flow behavior is often described by the simple Binghamconstitutive law. LÄS MER
