  1. 1. Topographic Control of Groundwater Flow

    Author : Lars Marklund; Anders Wörman; Shulan Xu; Roy Haggerty; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Modeling; Topography; Spectral analysis; Fourier series; Exact solu-tions; Multi-scale; Grundvatten; Modellering; Topografi; Spektralanalys; Fourier serier; Analytisk lösning; Flerskalig; Hydrology; Hydrologi; Environmental engineering; Miljöteknik;

    Abstract : Gravity is the main driving force for groundwater flow, and both landscape topography and geology distribute the effects of gravity on groundwater flow.  The groundwater table defines the distribution of the potential energy of the water. READ MORE

  2. 2. Atlantic Water in the Nordic Seas : A satellite altimetry perspective on ocean circulation

    Author : Sara Broomé; Johan Nilsson; Jonas Nycander; Léon Chafik; Michael A. Spall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean climate; ocean heat transport; sea surface height; topographic control; Lagrangian trajectories; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The Atlantic Water in the Nordic Seas contributes to the mild climate of Northern Europe and is the main oceanic source of heat for the Arctic. The northward bound transport of the warm and saline Atlantic Water is mediated by a topographically constrained cyclonic boundary current along the Norwegian continental slope. READ MORE

  3. 3. A Topographic Study of Functional Surfaces

    Author : Robert Ohlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cylinder bore; 3D surface roughness; topography; expert system; AFM; relocation; replication; instrumentation; functional demands;

    Abstract : Surface topography through the years has taken on increased importance, because of the rise in quality demands. The surface often has to meet additional functional demands when products become more complex in accordance with customer preferences. READ MORE

  4. 4. Grafted Molecular Layers for Control of Surface Properties

    Author : Gunnar Dunér; Andra Dédinaité; Stefan Zauscher; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The goal of this thesis work was to develop responsive surface grafted brushlayers for control of surface properties and to gain insights in the molecular mechanisms that control these properties. Three types of grafted layers were investigated, as outlined below. READ MORE

  5. 5. Ulcerative colitis and cancer with special reference to the increased colorectal cancer risk

    Author : Per Karlén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Ulcerative colitis; cancer; inflammatory bowel disease; colorectal cancer; colonoscopic surveillance; epidemiology; flow cytometry DNA; Sialyl-Tn antigen; primary sclerosing cholangitis; hepatobiliary tract; case-control studies;

    Abstract : The association between ulcerative colitis (UC) and cancer in a defined geographical region in Sweden was analyzed. UC patients have an increased overall risk of cancer of 40%, mainly due not only to the well-known increased risk of colorectal cancer (CRC) but also to the risk of hepatobiliary cancer associated with primary sclerosing cholangitis (PSC).
