  1. 1. Public e-Service Stakeholders : A study on who matters for public e-service development and implementation

    Författare :Ida Lindgren; Karin Axelsson; Göran Goldkuhl; Leif Flak; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public e-service; stakeholders; e-government; user involvement; Offentliga e-tjänster; intressenter; e-förvaltning; användarmedverkan;

    Sammanfattning : Public e-services are progressively used as a means for governmental agencies to interact and exchange information with citizens and businesses. These services are typically Internet-based and are meant to fulfill the three overarching objectives of egovernment; (1) to improve citizens’ interactions with the government, (2) to make governmental organizations more efficient and effective, and (3) to increase the transparency of government and lead to a more democratic society.

  3. 2. The evolutionary history of Geum (Rosaceae, Colurieae) : a study of ancient allopolyploid speciation

    Författare :Jenny E. E. Smedmark; Birgitta Bremer; Pamela S. Soltis; Stockholms universitet; []
    Nyckelord :Geum; Rosaceae; molecular phylogeny; allopolyploidy; morphological evolution; gynoecial development; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Allopolyploid speciation plays an important role in flowering plant evolution. Its contribution to diversity has been suggested to be significant in Geum. LÄS MER

  4. 3. Specific surface area of some minerals commonly found in granite

    Författare :Isabelle E. Dubois; Maria E. Malmström; Bo Strömberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Granite; Mineral; Surface area; BET; Sorption; Particle size;

    Sammanfattning : The specific surface area, determined by the BET method, is a parameter often used to scale results of mineral studies of surface reactions in terms of rate and capacity to the field scale. Such extrapolations of results from small-scale laboratory experiments to the field-scale are important within many environmental applications. LÄS MER

  5. 4. Benefits of Pharmacometric Model-Based Design and Analysis of Clinical Trials

    Författare :Kristin E Karlsson; E Niclas Jonsson; Mats O Karlsson; Anders Grahnén; Michael K Smith; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; model-based analysis; pharmacometrics; modeling; disease progression; NONMEM; SAEM; Importance sampling; repeated time-to-event; RTTCE; RCEpT; NIH stroke scale; Barthel index; internal validation; external validation; study power; study design; PHARMACY; FARMACI; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Sammanfattning : Quantitative pharmacokinetic-pharmacodynamic and disease progression models are the core of the science of pharmacometrics which has been identified as one of the strategies that can make drug development more effective. To adequately develop and utilize these models one needs to carefully consider the nature of the data, choice of appropriate estimation methods, model evaluation strategies, and, most importantly, the intended use of the model.

  7. 5. Nitrate stable isotopes and major ions in snow and ice from Svalbard

    Författare :Carmen Paulina Vega Riquelme; V. A. Pohjola; R. Pettersson; E. Isaksson; C. E. Bøggild; Kumiko Goto-Azuma; Uppsala universitet; []
    Nyckelord :nitrate stable isotopes; nitrate; NOx proxies; ice cores; percolation; ion relocation; Svalbard; stabila isotoper av nitrat; nitrat; indikator för kväveoxider; iskärnor; perkolation; joniska omlokalisering; Svalbard; Earth Science with specialization in Physical Geography; Geovetenskap med inriktning mot naturgeografi;

    Sammanfattning : Increasing atmospheric reactive nitrogen (Nr), as consequence of human activities, has generated accumulation of nitrate (NO3-) in Arctic regions. The Arctic has fragile nitrogen limited ecosystems that can be altered by increases of dry or wet deposition of Nr. LÄS MER
