    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; optimal control methods; dynamic programming; hybrid vehicles; Automotive emissions control; three way catalyst modelling;

    Abstract : The legal bounds on both toxic and carbon dioxide emissions from automotive vehicles are continuously being lowered, forcing manufacturers to rely on increasingly advanced methods to reduce emissions and improve fuel efficiency. Though great strides have been made to date, there is still a large potential for continued improvement. READ MORE

  3. 8. Towards low-emitting and sustainable particle and fibreboards : Formaldehyde emission test methods and adhesives from biorefinery lignins

    Author : Venla Hemmilä; Stergios Adamopoulos; Luísa Maria Hora Carvalho; Linnéuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Wood board industry; chamber methods; dynamic microchamber DMC ; bio-based adhesives; lignosulfonates; supercritical water hydrolyzed lignin; crosslinkers; fibreboards; particleboards; Forestry and Wood Technology; Skog och träteknik;

    Abstract : High volumes, fast production speed, and low material costs have been historically the driving factors of the particle- and fibreboard industries. However, in recent years the fossil-fuel dependency and health issues of the formaldehyde-containing adhesives used in the production have gained attention from both legislators and consumers.

    Abstract : By Year 2050, the EU has committed itself to reducing greenhouse gas emissions by 80%–95%relative to the levels in 1990, so as to contribute to global efforts to limit the long-term globalaverage temperature increase to.... READ MORE

  5. 10. Taxation of intermediate goods : a CGE analysis

    Author : Lars Bohlin; Lars Hultkrantz; Mats Nilsson; Örebro universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Optimal taxation; energy taxation; environmental taxes; emission trading; climate policy; carbon leakage; CGE-analysis; input-output tables; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Economics; Nationalekonomi; Economics; Nationalekonomi;

    Abstract : This dissertation is concerned with tax rates for the use of commodities in general, and energy in particular. Computable General Equilibrium (CGE) models are used to analyze the normative question of whether the tax rate for intermediate use by firms should be the same as the tax rate for final consumption by households.
