Popular Abstract in Swedish Två observationer tjänar som utgångspunkt för denna avhandling: (1) globaliseringens allt snabbare och mer eller mindre gränslösa flöde av information har medfört ökad press på företag och organisationer, liksom stater och regioner, att ständigt förnya sig för att kunna behålla sin konkurrenskraft. (2) kunskapsintensiv industri tenderar att samlas i geografisk närhet tiThe accelerated speed and intensity of global interconnections in all segments of society during the last couple of decades have had a profound impact on the workings of contemporary capitalism. Increased pressure is put on national and regional economies to continuously upgrade their competitive advantages, at the same time as new learning opportunities occur at a faster rate than ever. For reaso

Regulation of violaxanthin de-epoxidase (VDE) involves a conformational change at low lumenal pH, followed by binding of the enzyme to the thylakoid membrane. The role of histidine residues in this process was studied by release of unbound enzyme from thylakoids upon sonication, on a pH scale from 4.7 to 7.1. The co-operativity for binding of spinach VDE (four histidines) to the membrane was found

The multi-layer dynamic model SAFE was applied to the forested catchment istebna (Southern Poland), to study recovery from acidification. Environmental pollution in the area has been historically high. The model uses data from an intensive monitoring plot established in 1999 in a spruce stand, which was planted in 1880. Observations showed that the soil was depleted of base cations. The measured b

OPENLAND3 belongs to a suite of computer programs included in the POLLSCAPE simulation model. These programs make it possible to calculate estimates of pollen loadings in lake basins or bogs using vegetation data. OPENLAND3, written in Visual Basic 6, is designed to produce appropriate vegetation data files from vegetation maps stored in a Geographical Information System. It calculates percentage

Pioneering work in the last century has resulted in a widely accepted paradigm that primary production is strongly positively related to temperature and water availability such that the northern hemispheric forest carbon sink may increase under conditions of global warming. However, the terrestrial carbon sink at the ecosystem level (i.e. net ecosystem productivity, NEP) depends on the net balance

The N-terminal RNA binding domain of U1A has been shown to fold in a two-state process without accumulating any intermediates. U1A has a symmetrically curved chevron plot which seems to result mainly from changes of the transition state. At low concentrations of denaturant the transition state occurs early in the folding reaction, whereas at high denaturant concentration it moves close to the nati
