In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). Therefore, the drying rates achieved in through-drying are often several times higher than in contact drying proc

The aim of this thesis was to study competitive adsorption of milk proteins during spray-drying. For this purpose, a new surface sensitive method was developed which measures the quantitative amount of specific proteins at the powder surface. The new method is based on steady-state fluorescence measurement of pyrene labelled proteins with oxygen gas phase quenching at the powder surface. The milk

In a so-called globalized world characterized by the continuous movement of people and pathogens crossing national borders, the Nordic welfare states can, arguably, no longer be studied as isolated entities removed from their broader international and geopolitical context. For example, as was aptly illustrated by the 2009 swine flu outbreak, infectious diseases spread at a pace unmatched by previo

This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. Patients were examined during first 14 days after the bleed. Flow velocities in normo- ver

Popular Abstract in Swedish Avhandlingen är en studie av hur energianvändning och luftföroreningar i Polen, Estland, Lettland och Litauen har förändrats under övergången till marknadsekonomi efter 1989. Avhandlingen består av sex artiklar, vilka behandlar tre aspekter av dessa förändringar. I de tre första artiklarna analyseras energistrukturen i de baltiska länderna Artikel I) och Polen (ArtikelThis thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. The first group of articles analyses the structure of energy use in the Baltic states (Article I) and Poland Articles II and III) at the outset of transitio

Tracing secondary rays, such as reflection, refraction and shadow rays, can often be the most costly step in a modern real-time ray tracer. In this paper, we examine this problem by using suitable ray coherence measures and present a thorough evaluation of different reordering heuristics for secondary rays. We also present a simple system design for more coherent scene traversal by caching seconda

Within cognitive science, two approaches currently dominate the problem of modeling representations. The symbolic approach views cognition as computation involving symbolic manipulation. Connectionism, a special case of associationism, models associations using artificial neuron networks. Peter Gardenfors offers his theory of conceptual representations as a bridge between the symbolic and connecti

Kort presentation av bibliotekarieutbildningen i Lund och dess speciella profil.

Popular Abstract in Swedish Denna skrift behandlar marklagring av värme, kyla och kärnavfall.The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. All these storage systems induce multidimensional, time-variable thermo-hydr

There is a gap between software testing research and practice. One reason is the discrepancy between how testing research is reported and how testing challenges are perceived in industry. We propose the SERP-test taxonomy to structure information on testing interventions and practical testing challenges from a common perspective and thus bridge the communication gap. To develop the taxonomy we fol
