n this paper a new model, tailor-made for nutrient deficient aerobic COD removal, is presented. The Activated Sludge Model No. 1 is chosen as a basis for model development. The original model is extended to include (1) phosphorus state variables; (2) phosphorus and nitrogen limited heterotrophic growth; (3) additional 'luxury' uptake of phosphorus and (4) a separate active biomass component to mod

Popular Abstract in Swedish Två av de viktigaste polyaminerna påträffades redan i slutet av 1600-talet, som kristaller i tjursperma och har därför fått namnen spermin och spermidin. Dessa aminer bildas från en annan substans, putrescin, som först isolerades från ruttnande kött. Namnet putrescin kommer från engelskans putrefaction, som betyder förruttnelse. Polyaminer, som kemiskt sett är positivt The polyamines putrescine, spermidine and spermine are essential for cell growth and differentiation. The biosynthesis of polyamines are tightly regulated by feedback mechanisms involving two enzymes, namely ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (AdoMetDC). This thesis deals with the mechanisms behind the polyamine-mediated feedback control of these enzymes. The poly

In this paper, technical and economic prerequisites to attain reduced carbon dioxide (CO2) emissions through the use of biomass-based energy carriers in the transportation sector are studied. CO2 emission reduction per unit of land used for biomass production as well as costs for CO2 emission reduction are estimated when substituting rape methyl ester, biogas from lucerne, ethanol from wheat and e

Essay on the development of the Gunvald Larsson character in the Beck film series 1997-2010.

This publication is part of a project called Direct and Indirect Load Control in Buildings performed at the Division of Energy Economics and Planning, Department of Heat and Power Engineering, Lund University, Sweden. Peak load problems have attracted considerable attention in Sweden during last three winters, caused by a significant decrease in available reserve power, which is a consequence of p

The Swedish Air Navigation Service Provider in cooperation with the University of Lund aims at developing a model for supporting continuous improvements and learning focusing on safety in air traffic control. This paper focuses on relationships between the safety culture and the psychosocial working environment. These areas were studied using questionnaires at the two main air traffic control cent
