  1. 1. Tracing Copper from society to the aquatic environment : Model development and case studies in Stockholm

    Författare :Qing Cui; Maria E. Malmström; Olle Wahlberg; KTH; []
    Nyckelord :diffuse source; source analysis; sediment pollution levels; urban lake; Copper; Stockholm archipelago; SFA; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Copper remains at elevated levels in the aquatic environment of Stockholm due to diffuse urban sources. Management of these diffuse sources requires their quantification but they cannot be measured directly by field observations. LÄS MER

  3. 2. Nonpoint source water pollution management : Monitoring, assessment and wetland treatment

    Författare :Lorin Reinelt; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The management of nonpoint (diffuse) sources of-water pollution has received increased attention during the past decade. New techniques that aid in the identification and assessment of these diffuse sources can increase the chances for success of nonpoint source control efforts. LÄS MER

  4. 3. A Business Ecology Perspective on Community-Driven Open Source : The Case of the Free and Open Source Content Management System Joomla

    Författare :Markus Radits; Alf Westelius; Nils-Göran Olve; Carl-Johan Petri; Anna Öhrwall Rönnbäck; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis approaches the phenomenon of open source software (OSS) from a managerial and organisational point of view. In a slightly narrower sense, this thesis studies commercialisation aspects around community-driven open source. LÄS MER

  5. 4. Modelling of Substance Flows in Urban Drainage Systems

    Författare :Stefan Ahlman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; urban stormwater; source control; modelling; diffuse pollution; BMPs;

    Sammanfattning : Stormwater is recognised as a large contributor of toxic substances to receiving waters. Different measures to manage stormwater quality have been proposed, including structural and non-structural best management practices (BMPs). Computer models have become useful tools for the analysis, evaluation and design of these BMPs. LÄS MER

  7. 5. Model-based Approaches to Diffuse Optical Imaging and Dosimetry

    Författare :Johan Axelsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photodynamic therapy; diffuse light propagation; fluorescence; imaging; dosimetry; inverse problem;

    Sammanfattning : The work within this thesis investigates Photodynamic therapy and Fluorescence imaging for therapeutics and visualization of deeply embedded lesions. Photodynamic therapy (PDT) is a cancer treatment modality that can eradicate tumors when light, a photosensible drug and oxygen are present. LÄS MER
