In this paper we present a model of the dissolved organic carbon (DOC) concentrations and fluxes in mire water based on the convection-dispersion equation. The dynamics of sorbed, potentially soluble organic carbon (SPSOC) in the peat matrix are simulated in parallel with DOC. First, the model is applied solely to stagnant water conditions in order to interpret the results of laboratory peat incub

The development of integrated pest management is hampered by lack of information on how insect pest abundances relate to yield losses, and how pests are affected by control measures. In this study, we develop integrated pest management tactics for Apion spp. weevils (Coleoptera: Brentidae) in seed production of red clover, Trifolium pratense L. We tested a method to forecast pest damage, quantifie

Flexibility as well as constraints to the evolution of migration routes has the possibility of affecting large-scale patterns of geographical ranges of animals both by facilitating, but sometimes restricting, accessibility to and colonization of new regions. This dissertation concerns the broad-scale effects migration has on the distributional patterns of birds in the Arctic. I studied the circum

Malignant glioma is, with rare exceptions in younger adults, an uncurable brain tumor, as very few survive more than 1-2 years after diagnosis. Despite advances in recent years, current treatments such as surgery, radiotherapy and chemotherapy only prolongs the life of the patients. Because of the poor prognosis, several additional therapies have been investigated and are under development, such a

In order to meet the unprecedented challenge of feeding an increasing population while curbing associated environmental impacts a fundamental change in the current food system is required. Such a shift needs an active facilitator who could set and implement the sustainability agenda in the food supply chain. Recently, it has been argued that retailers might become a vital agent of change towards s

I share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. Gliding flight performance of a jackdaw was measured in a wind tunnel and I conclude that the current model for predicting optimum wingspan as a function of forward gliding

Load demand in residential houses is a significant contributor to peak load problems experienced by utilities. The knowledge about demand variation in households is fairly limited as well as the use of various tools to analyze the demand. Many utilities have recently installed interval (hourly) metering at their residential customers. The availability of hourly data is a significant progress, howe

Critical infrastructures provide society with services that are essential for its functioning and extensive disruptions of these give rise to large societal consequences. Vulnerability analysis gives important decision information concerning improving their ability to withstand strains. To analyze vulnerabilities in infrastructures models for estimating consequences due to failures are needed. Con

The impact of European Union law on the regional and local levels in the Member States has been underestimated for a long time now. Today, however, it is clear that the impact of European Union law on these levels is important, not least as a consequence of the deregulation that has been carried out in most Member States in recent years. As local markets open up for competition, the scope of EU la

It is important that the costs and effort in making a Virtual Reality (VR) model support its purpose in the specific context in which it is used. The present research aims to clarify which properties in VR-models contribute to improved experience of aspects of the model that are relevant in the use context and which therefore improve the models’ usability in the social processes of which they are

Concerns have been raised about the marketization of science through the prevailing funding regime. However, the present article will discuss how it comes that the potentially marketable stem cell science is not more commercialized than what is currently the case. We approach this question by analysing discursive pluralism in defining the value of stem cells within a grant allocation process. More

Ischemic and traumatic brain damage are major causes of disability and death. While much effort has been spent to develop pharmacological treatments for these conditions, no neuroprotective drugs are in clinical use. Neuronal death following ischemia and trauma occurs in selected cell populations of the brain at various time points after the insult. It is believed that death of neurons are in part

Today, the demand for shorter lead times, shorter production runs and more diversified products is a general market trend, which puts pressure on logistics systems. When adapting to this trend, agile manufacturing becomes increasingly important. Flexible printing activities, in particular, are needed when products and packaging designs increasingly are to be adapted for niche markets. This study s

This article reports model experiments where vocal tract profiles of high and mid unrounded front and high rounded back vowels were systematically modified to simulate small constriction shifts along the hard or soft palate, in order to test A. M. Bell's century-old proposal that small shifts of tongue arch fronting or retraction would yield audible shifts of vowel timbre. Such differences were cl
