  2. 16. Opportunities and challenges of surface scattering at next generation neutron sources

    Author : Franz Alois Adlmann; Henrich Frielinghaus; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GISANS; data reduction; off-specular; neutron scattering; reflectometry; complex fluids; rheology;

    Abstract : Complex fluids and soft matter are ubiquitously found in the world and all contacts in life are made over surfaces. To describe the mechanical behavior of such substances, rheological methods are used. Flow instabilities are a big challenge in rheology since they will be reflected in the macroscopic variables probed, like e. g. READ MORE

  4. 17. Nano-particulate Silica Hydrogels Imaged in 2D and 3D using TEM: Effects of local pore structure on mass transport and applications in aggregation dynamics

    Author : Charlotte Hamngren Blomqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; silica gel; colloidal silica gel; interconnectivity; nanoporous; electron tomography; silica nanoparticle gel; mass transport; nanostructure; accessible volume fraction; 3D structure;

    Abstract : Porous materials are frequently used in everyday applications including food science, pharmaceuticals, fuel cell membranes, batteries and solar cells. A key aspect in these porous materials is how their micro- and nano-structure affect the internal transport of for example water, particles or charges. The transport is a three-dimensional process.

  5. 18. The human placenta : an angiographic study

    Author : Ulla Ullberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Anatomy; angiography; fractal dimension; FVW; Hyrtl s anastomosis; IUGR; placenta; SGA; umbilical artery; vessel pattern.;

    Abstract : The arterial vessels from the umbilical cord spreading over the chorion and its cotyledonary branches constitute the main body of the placental vascular tree. In the present study it was visualized by angiography and related to placental developmental factors. READ MORE

  6. 19. All Around Logic Synthesis

    Author : Maxim Teslenko; Hannu Tenhunen; Michel Berklaar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; graph dominators; FPGA mapping; redundancy removal; RBN; Computer science; Datavetenskap;

    Abstract : This dissertation is in the area of Computer-Aided Design (CAD) of digital Integrated Circuits (ICs). Today's digital ICs, such as microprocessors, memories, digital signal processors (DSPs), etc., range from a few thousands to billions of logic gates, flip-flops, and other components, packed in a few millimeters of area.

  7. 20. Inhibition of PDGF receptor signaling in tumor stroma : Effects on interstitial hypertension, drug uptake and therapeutic response

    Author : Kristian Pietras; Sven Påhlman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PDGF; tumor; stroma; tyrosine kinase inhibitor; combination therapy; Onkologi; Oncology; Onkologi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : The role of platelet-derived growth factor (PDGF) in malignancies involves both autocrine and paracrine stimulation of cells within the tumor. The interstitial fluid pressure (IFP) is one of the forces that govern the transvascular flow of fluids. READ MORE
