The hypothesis of this thesis is that climate models should take structural vegetation changes that operate on interannual to centennial time scales into account in order to simulate climate change in a more realistic manner. To evaluate this hypothesis, a regional Earth System Model (ESM) has been developed, validated and applied over Europe. The model has enabled the identification of a number o
Cytokines like interleukin-1beta (IL-1beta) and tumor necrosis factor alpha (TNFalpha), released during the inflammatory process, play important roles in the development of airway hyperresponsiveness. The effects of these cytokines are mediated by cell surface receptors, specific for each cytokine. The expression of cytokine receptors is a dynamic process, where receptors can be up- or down-regula
Research has been pointing out that productivity in the building industry is stagnant and in some cases declining. Poor productivity of craftsmen is one of the causes of cost and time overruns on building projects. Productivity of labour is particularly important especially in developing countries where most of the building work is still carried out on manual basis. The objective of this research
Popular Abstract in Swedish Rovdjur påverkar strukturen och artsammansättningen i de flesta system. Både genom att äta upp bytesdjur och genom att inducera olika typer av försvar hos bytesdjuret kan rovdjur påverka andra organismer i systemet. Att undvika att bli upptäckt, och därmed sannolikt uppäten, av ett rovdjur är grundläggande för fortlevnaden hos alla bytesdjur. Under utvecklingens gång haPredator released chemical cues provide a valuable source of information to prey organisms that can be used to alter their behaviour in order to reduce predation risk. In this thesis, I have examined under what circumstances chemical cues may be used by prey, and if prey discriminate between different cues. I have also investigated the role of predator experience in prey ability to detect and resp
Øresund EcoMobility contributes to knowledge creation for sustainable transport and green logistics, city transport, and energy systems with a specific focus on the conditions and needs of the Øresund region. In this book, long distance goods transport and strategies for green corridors through the Øresund and Europe are studied, multi-criteria models for analysis in transport and infrastructural
In order to accomplish oxidation of alkylaromatic compounds, both cations, which serve as adsorption centers, and oxygen species of suitable bond strength are needed. When compared to partial oxidation, relatively weakly bonded oxygen species are involved in combustion. On the basis of these criteria, using a simple model of the active ensemble, a relationship between reaction rate and bond streng
Popular Abstract in Swedish Nätverk av nervtrådar påvisades kring koronara artärer och vener från marsvin och människa. Medelst immunhistokemiska metoder demonstrerades olika signalsubstanser i anknytning till dessa nervtrådar och i olika delar av kärlväggen (endotelet, media, adventitia), och det påvisades hur vissa av dessa substanser var lokaliserade i samma vesikler av ovan nämnda nervtrådar. A network of perivascular nerve fibres was demonstrated in coronary arteries and veins from guinea-pig and man. Nerve fibres displaying immunoreactivity to neuropeptide Y (NPY) had a distribution pattern similar to those containing immunoreactivity to tyrosine hydroxylase. Immunoreactivity to substance P and calcitonin gene-related peptide (CGRP) occurred in the same varicose nerve fibres, which w
OBJECTIVE: 5-azacytidine (azacytidine), a DNA hypomethylating agent, was recently approved as the first therapeutic agent for the treatment of myelodysplastic syndromes. The present subcutaneous dosing schedule, 75 mg/m(2) for 7/28 days, is based on early clinical studies and may constitute a practical problem for patients. The present in vitro study aimed at evaluating the pharmacodynamics of aza
The phylogeny of the Patagonian-Antarctic genus Himantormia is investigated with nuclear ITS rDNA sequences in PAUP. The monotypic genus Nimisia is synonymized with Himantormia, and the new combination H. deusta is proposed. The secondary chemistry was investigated using HPLC; protocetraric, stictic, succinprotocetraric and confumarprotocetraric acids were detected in H. deusta for the first time,
We present a polynomial time method for identifying the maximal set in excess demand at a given payoff vector. This set can be used in "large" partnership formation problems to identify the minimum element in the set of individually rational payoff vectors at which there is no overdemanded set of agents. This minimum element corresponds to the minimum Walrasian equilibrium price vector in a specia
