Popular Abstract in Swedish Den här avhandlingen är ett bidrag till utvecklingen av en metodik som gör det möjligt att med hjälp av fossila pollen d.v.s. pollen som lagrats i mossar och sjöar, rekonstruera historiska och förhistoriska landskap så precist som möjligt vad gäller utbredning av skog, olika typer av öppen mark samt vegetationens sammansättning. Den tolknings metodik som för närvarande Fossil pollen records retrieved from peat and lake sediments have great potential for quantifying past plant cover. This thesis is a contribution to the development of a palynological interpretation tool for reconstructing past cultural landscapes in terms of plant abundance and distribution. The aims of this thesis are (1) to explore pollen-vegetation relationships in the ancient, traditional cul

Autoimmune thyroid disease is common among women of childbearing age. Thyroid autoantibodies are predominantly of the immunoglobulin G (IgG)-type and pass the placental barrier from mother to child. Recent studies have suggested a pathogenetic role for transplacentally transmitted autoantibodies in the development of autoimmune disease. The aim of the present study was to investigate if children a

Role of R-(-)-deprenyl in adhesion of neuronal and non-neuronal cells. The beneficial effect of the anti-parkinsonian monoamine oxidase-B inhibitor, R-(-)-deprenyl has been shown in a number of different diseases, such as Parkinson's and Alzheimer's disease, atherosclerosis or tumor formation. The role of the cytoskeleton, the main component of cell adhesion, has been suggested in the development

The subject of this study is the re-intensified dispute between rhetoric and philosophy in the times of the Second Sophistic. The focus of our investigation has been on two authors of this period who have left behind treatises the explicit purpose of which is to attack or defend rhetoric: Sextus Empiricus who is sharply criticising rhetoric and Aelius Aristides who is defending it. Our purpose has

The synthesis and contents of extracellular non-collagenous matrix macromolecules was studied in early and late human osteoarthritic (OA) cartilage obtained at surgery for sarcomas in the lower extremities (normal and early OA) or for total knee replacement (late stage OA). The early OA samples were those that had some fibrillation in the joint by visual examination. One group had fibrillation in

A typology of churched and unchurched religions is developed and then used to analyse the status of unchurched spirituality in the United States, Sweden, and Japan. In the United States, churched religions remain strong, while most of those who say they have no religious preference are quite religious, merely unchurched. In Sweden, the lack of participation in the state church seems to be more tha

Proteinase-activated receptor 2 (PAR-2) is a G protein-coupled receptor related to the thrombin receptor. PAR-2 can be activated by trypsin and by synthetic peptides corresponding to the new amino terminus generated by activating proteolytic cleavage. We show in this report that intravenous injection of PAR-2 agonist peptides has dramatic effects on arterial blood pressure in anesthetized rats. Th

The article presents the outlines of an integrative theory of meaning based on the concept of value, understood both as a biological and as a socio-cultural category, synthesizing ideas from evolutionary and developmental psychology, semiotics and cybernetics. The proposal distinguishes between four types of meaning systems, cue-based, associational, mimetic and symbolic, forming an evolutionary a

Atmospheric deposition of N and S appears to have caused nutrient imbalance in Norway spruce stands in southern Sweden. This calls for a change of forest management to procedures that promote nutrient balance. Studies have shown lower soil acidity in Norway spruce/deciduous mixed stands than in spruce monocultures, but the tree nutrient status in such mixtures has not been much investigated so far

The cyclisation conditions for the formation of bicyclo[2.2.2]octan-2,6-di one (1) from 3-substituted cyclohexanones 2 and 3 have been re-investigated. Use of a medium consisting of isobutyric anhydride and trifluoroacetic acid resulted in a simplified and reproducible method for large-scale synthesis of this compound.

The aim of this study was to investigate the effect of training on the in vivo tibial structural strength during the development of post-ovariectomy osteoporosis. Seventeen mature Wistar rats (215 g) were ovariectomized and randomized into two groups. The sedentary control group was kept cage confined, while 3 days postoperatively the trained group started treadmill running with high intensity for

Archaeology has become a potent element in themed environments that abound in contemporary popular culture. This short article reviews the archaeological motifs that can be found in environments such as Disneyland and on the Las Vegas Strip. They provide a set of imagery to which people can easily relate and that immerses them in a world different from the normal routines and restrictions of every

Data from full scale experiments are collected and organized in a database. A statistical method is developed to evaluate the uncertainty in predictions of smoke transport models. The method is based on a regression analysis of measured and predicted data. The computer program CFAST is evaluated to exemplify the statistical method. The uncertainty is quantified with a regression coefficient and th
