  1. 1. Getting the transport right - for what? : What transport policy can tell us about the construction of sustainability

    Författare :Mathilde Rehnlund; Björn Hassler; Fredrika Björklund; Dalia Mukhtar-Landgren; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; problem representation; transport policy studies; policy discourse; sustainable transport studies; urban transport studies; poststructuralist policy studies; Environmental Studies; Miljövetenskapliga studier;

    Sammanfattning : This thesis studies transport as a governing tool that shapes the physical environment and human society, as well as having environmental impacts. The aim is to learn what policy for transport can say about what sustainability means and does. LÄS MER

  3. 2. Intestinal transport of levodopa : Implications for the therapy of Parkinson's disease

    Författare :Dag Nilsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Parkinson s disease; levodopa. duodenal Infusion; intestinal permeability; positron emission tomography; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Levodopa has been the basic treatment of patients with Parkinson's disease for the last 30 years. However, with time nearly all patients develop fluctuations in motor performance correlated to levodopa plasma concentrations. LÄS MER

  4. 3. Time, justice and the future of mobility : Essays in philosophy of transport

    Författare :Maria Nordström; Karin Edvardsson Björnberg; Sven Ove Hansson; Muriel Beser Hugosson; Anders Karlström; Ibo van de Poel; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; transport justice; mobility; accessibility; philosophy of the city; Filosofi; Philosophy;

    Sammanfattning : This thesis in philosophy consists of an introduction and five papers on three themes related to transport: valuations of time, the metric of transport justice, and future mobility solutions. The first paper analyses the properties of time as an economic resource taking into account literature on behaviour concerning time.

  5. 4. Collisional transport in edge transport barriers and stellarators

    Författare :Stefan Buller; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fusion; tokamak; plasma physics; stellarator; impurity transport; collisional transport; transport; pedestal;

    Sammanfattning : Nuclear fusion has the potential to generate abundant and clean energy. In magnetic confinement fusion, the temperatures needed to achieve fusion are obtained by confining a hot plasma with magnetic fields. LÄS MER

  7. 5. Competition in Public Transport : Essays on competitive tendering and open-access competition in Sweden

    Författare :Andreas Vigren; Svante Mandell; Jan-Eric Nilsson; Nash Nash; Statens väg- och transportforskningsinstitut; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Contract; Tender; Bus; Economic efficiency; Competition; Location; Transport operator; Depot transp ; Impact study; Railway; Line transp ; 02 Road: Economics; 02 Road: Economics; 111 Road: Public transport; 111 Road: Public transport; J13 Railway: Economics; J13 Railway: Economics; Transportvetenskap;

    Sammanfattning : The results of this work show that the cost efficiency of tendered bus services is similar across all Swedish counties, except for the more high-density counties where efficiency is lower. Considerably lower efficiency is also found for contracts with services run in-house by the Public Transport Authority (PTA), compared to when the same service is run by a private actor. LÄS MER
