The inability of organisations to develop successfully and their lack of a holistic view and of relevant quantitative facts are factors that played a major role in my choice of a research area for this and my licentiate thesis (Ljungberg, 1994). These two theses together represent the work conducted for the PhD degree. There is a strong need in this research area for increased insight into the de

This introduction to the biology of standing waters integrates the effects of abiotic constraints and biotic interactions at both the population and community level, and examines how the distribution and success of different organisms in this freshwater habitat can be explained and predicted

Abstract: Parkinson’s disease (PD) is a common neurodegenerative disorder. There is no proven protection, but many treatments can partially improve symptoms. The disease is caused by monogenetic mechanisms in very few cases, but for the majority of patients the etiology is unknown. Epidemiological studies have identified a potential role for inflammation. The thesis investigates inflammation and i

Collagen-induced arthritis (CIA) is a T cell-dependent autoimmune disease that serves as an animal model for human rheumatoid arthritis. CIA can be induced in H-2q mice by a single immunization with the cartilage-specific protein type II collagen (CII). This study has focused on CII immunity and tolerance with respect to the interactions between antigen, antigen-presenting cells and T cells. CIA-r

Stadsplanering är ett komplicerat och mångfasetterad begrepp. Denna rapport är en förstudie om hur begreppet stadsplanering kan definieras och vilken möjlighet stadsplanering har för att påverkar stadens transporter, bebyggelsestruktur, resvanor, bilägande/användning, välfärdsfördelning (ex. segregation) och ekonomisk utveckling/handel. Rapporten utgår dels från en litteraturstudie, dels från inte

Popular Abstract in Swedish Tre av huvudets blodkärlsregioner - hjärnans, den h rda hjärnhinnans och tinningens puls dror, har undersökts med avseende p förekomst av nerver inneh llande signalsubstanser som kallas neuropeptider. Tv av dessa är substans P (SP) och kalcitonin gen-relaterad peptid (CGRP) vilka finns i nerver som förmedlar känselupplevelser, till exempel smärta. Andra är neuropeptid YThe sensory neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP) are present in human cerebral, meningeal and temporal arteries, as are peptides associated with the sympathetic (neuropeptide Y, NPY) and parasympathetic (vasoactive intestinal peptide, VIP) nervous system. NPY is a vasoconstrictor in cerebral and meningeal arteries and potentiates noradrenaline (NA) as a vasocon

1. INTRODUCTION Geographers at the University of Lund have been active in research on desertification/ land degradation and environmental change monitoring of African drylands since the mid 1970’ies and of Asian drylands since the beginning of the 1990’ies. The results obtained so far do not confirm the concept of desertification as a mainly man made phenomena but indicate that the importance of c

Popular Abstract in English The thesis that you are reading at this moment was printed using climate compensated paper, a sign that consciously or not you are contributing somehow to control the current environmental issues in our planet. It would not be nice if every single article used in your daily life contains information about how environmentally friendly that product is? We have to think “bOxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage. This has called

The production of ethanol based on lignocellulosic biomass requires the fermentation of a hydrolysate containing hexose and pentose sugars in an inhibitory environment. In fact, the lignocellulosic hydrolysate obtained from pretreatment and hydrolysis of the raw material contains a variety of inhibitory compounds, including (i) the furaldehydes 5-hydroxymethyl-2-furaldehyde (HMF) and 2-furaldehyde

Three titania polymorphs, anatase, rutile, and TiO2(B), were used as supports for vanadia. Catalysts with nominal loadings corresponding to 1.5 and 5 theoretical layers were prepared. True monolayer samples were obtained by NH3(aq)-treatment of the samples with 5 nominal vanadia layers. Prepared catalysts were characterized by chemical analysis, ESR, and high-resolution electron microscopy. It was

Popular Abstract in English The food we consume is hardly, if ever, sterile. From fresh produce to processed products, foods harbor one or more types of microorganisms. The presence of some ‘beneficial’ microorganisms is desirable in food production, because they contribute to the characteristics of the final product, as, for example, in the production of wine, beer or cheese. In other cases, micrControl of the dissemination of pathogens in the food production chain is an on-going process with new challenges emerging as pathogenic bacteria evolve and express enhanced virulence characteristics. Staphylococcus aureus and Listeria monocytogenes are two notorious pathogens responsible for staphylococcal food poisoning (SFP) and listeriosis: a foodborne intoxication and an infectious disease re
