  2. 21. Modelling and Appraisal in Congested Transport Networks

    Author : Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport modelling; Transit Assignment; Appraisal; Congestion; Crowding; Cost-benefit analysis; Value of time; Congestion charge; Dynamic traffic assignment; Transportvetenskap; Transport Science;

    Abstract : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

  4. 22. Experimental studies of ion transport in cementitious materials under partially saturated conditions

    Author : Nilla Olsson; Avdelningen för Byggnadsmaterial; []
    Keywords : Cement; Bruk; Betong; Jontransport; Fukttransport; Sorptionsisoterm; Tillsatsmaterial; Kiselstoft; Masugnsslagg; Ciment; Mortier; Béton; Transport ionique; Transport d humidité; Sorption de vapeur d eau; Additions minérales; Fumée de silice; Laitier de haut fourneau granulé moulu; Cement; Mortar; Concrete; Ion transport; moisture transport; Water vapor sorption; Supplementary cementitious materials SCMs ; Silica fume; Ground granulated blast furnace slag;

    Abstract : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. READ MORE

  6. 24. New Approaches to Studies of Paracellular Drug Transport in Intestinal Epithelial Cell Monolayers

    Author : Staffan Tavelin; Per Artursson; Staffan Tavelin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; intestinal epithelium; tight junctions; cell culture; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Studies of intestinal drug permeability have traditionally been performed in the colon-derived Caco-2 cell model. However, the permeability of these cell monolayers resembles that of the colon rather than that of the small intestine, which is the major site of drug absorption following oral administration.

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

    Author : Mathilde Rehnlund; Björn Hassler; Fredrika Björklund; Dalia Mukhtar-Landgren; Södertörns högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE
