  2. 1. Role of a dry port stakeholder network in intermodal transportation

    Author : Alena Khaslavskaya; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dry port; coopetition activities; dry port characteristics; Dry port concept; stakeholder network; intermodal transportation; stakeholder objectives; intermodal transportation challenges;

    Abstract : The concept of a dry port, which emerged from intermodal transportation research approximately 20 years ago, has gained popularity due to its financial benefits and positive environmental impact. The core idea behind the dry port concept is the establishment of high-capacity intermodal transportation in the seaport’s hinterland. READ MORE

  4. 2. Terrestrial organic carbon dynamics in Arctic coastal areas : budgets and multiple stable isotope approaches

    Author : Vanja Alling; Christoph Humborg; Carl-Magnus Mörth; Rüdiger Stein; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic carbon; DOC; POC; multiple stable isotopes; Laptev Sea; East Siberian Sea; Lena River; Arctic; residence times; degradation; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Arctic rivers transport 31-42 Tg organic carbon (OC) each year to the Arctic Ocean, which is equal to 10% of the global riverine OC discharge. Since the Arctic Ocean only holds approximately 1% of the global ocean volume, the influence of terrestrially derived organic carbon (OCter) in the Arctic Ocean is relatively high. READ MORE

  5. 3. Homogeneous Lean Combustion in Downsized Spark-Ignited Engines

    Author : Kristoffer Clasén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; lean combustion; emissons; transportation;

    Abstract : Emissions of greenhouse-gasses and noxious compounds from internal combustion engines propelling personal transportation vehicles is an imminent issue in the society. Therefore, it is vital to find means of reducing these emissions to decrease the impacts of transportation. READ MORE

  6. 4. Mitigating Off-Gassing and Self-Heating in Fuel Wood Pellets Storage : A Raw Materials Selection and Pre-Treatment Centred Approach

    Author : Workson Siwale; Jonas Berghel; Gunnar Henriksson; Michael Finell; Stefan Frodeson; Mani Sudhagar; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid biofuels; densified biomass; heat generation; off-gas emissions; carbon monoxide; carbon dioxide; methane; fatty and resin acids; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Wood pellets have become a preferred solid biomass fuel for heat and power generation due to their standardized nature, known properties, and consistent quality. However, pellets produced from fresh sawdust sometimes undergo self-heating and off-gassing during storage. This poses a challenge for their transportation and storage. READ MORE

  7. 5. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective

    Author : Lisa Näslund Eriksson; Leif Gustavsson; Antti Asikainen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest fuels; recovery systems; transportation; cost; primary energy use; CO2 emission; forest-fuel potential; life cycle perspective; Environmental engineering; Miljöteknik;

    Abstract : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. READ MORE
