Uncertainty Modelling in Hydrological Applications - Error Propagation Properties of Random Linear Systems

In hydrological models for water resources management and planning, the model output or design quantities are functions of the input data and a number of parameters that are essentially stochastic processes or random variables. The task of uncertainty analysis is to estimate the uncertainty characteristics of the model output in terms of the uncertainties in the input, model parameters and initial

Cardioprotection by estrogens: implications of observational studies

Women younger than 50 have a lower age-specific incidence of CVD than men. With advancing age this difference gradually disappears. These well-established facts provide the rationale for numerous primary and a few secondary intervention studies with ERT. With increasing sophistication and longer observation periods, both case-control and cohort studies agree on a cardioprotective effect by estroge

Testing and Applying Cointegration Analysis in Macroeconomics

Popular Abstract in Swedish Avhandlingen består av tre uppsatser som behandlar empiriska tillämpningar av makroekonomiska teorier. Uppsatserna är fristående från varandra, men knyts samman genom att kointegrationsanalys används i de empiriska analyserna. Kointegrationsanalys är en statistisk metod som syftar till att hitta långsiktiga samband mellan olika variabler i ett empiriskt datamaterial. EfThis thesis focuses on empirical applications and tests of macroeconomic theories. It consists of three fairly distinct essays, bound together by the common theme of the use of cointegration analysis in the empirical macroeconomic analysis. The first chapter is an introductory chapter, while chapter two, three and four contain the three essays. The first essay, Wage Formation and the Relation bet

A magnetostratigraphic comparison between 14C years and varve years during the late Weichselian, indicating significant differences between the time-scales

A 14C-dated magnetostratigraphy of absolute declination and inclination between 12500 and 10000 14C yr BP was recently developed for southern Sweden. Recently also the Swedish geochronological time-scale, based on c. 11 500 annually deposited clay-varves, was connected with the present. It should therefore be possible to compare the two chronologies with a reliable magnetostratigraphic record in a

Dizziness and fear of falling: A behavioural and physiological approach to Phobic Postural Vertigo

Popular Abstract in Swedish Yrsel är ett mycket vanligt symtom bland patienter inom olika specialiteter inom sjukvården. Orsaken bakom symtomen kan ligga i neurologiska sjukdomar, sjukdomar i innerörats balansorgan samt i psykiatriska sjukdomar, framför allt ångestsjukdomar. Medicinska undersökningar leder inte alltid till att orsaken till yrseln konstateras i en specifik sjukdom och ibland kan maDizziness is a common problem and it often co-exists with anxiety. Level of anxiety is the best predictor of handicap for dizzy patients. There is diagnostic controversy and few treatment programs for such patients. These patients can be labeled as panic disorder with agoraphobia or by the concept of Phobic Postural Vertigo which is characterized by dizziness or imbalance in standing or walking de

Maternity and bone mineral density

During pregnancy and lactation, changes occur in a variety of factors which have great potential to influence bone mineral density (BMD). Smoking habits, the level of alcohol consumption, the level of physical activity, body weight, soft tissue composition and hormone levels are all factors that change during the course of these conditions. Some of these factors are capable of increasing BMD, and

Population Dynamics of Resource Limited Plants and Their Pollinators

In this paper we build upon and generalize an earlier model of the interactions between a plant and its pollinator (Ingvarsson and Lundberg, 1995). In this model we assume that the performance of the pollinator population is directly linked to the size of the plant population. To avoid the problem of both populations growing exponentially we have, without loss of generality, assumed the plant popu

Novel quantitative trait Loci controlling development of experimental autoimmune encephalomyelitis and proportion of lymphocyte subpopulations.

The B10.RIII mouse strain (H-2r) develops chronic experimental autoimmune encephalomyelitis (EAE) upon immunization with the myelin basic protein 89–101 peptide. EAE was induced and studied in a backcross between B10.RIII and the EAE-resistant RIIIS/J strain (H-2r), and a complete genome scan with microsatellite markers was performed. Five loci were significantly linked to different traits and cli

Implementing Cognitive Semantics

This book is about how concepts are structured and processed. It is based on the findings in cognitive linguistics over the last decade, where thorough studies have been made about how concepts function. Concepts appear as image schemata, a spatial form of representation with very powerful properties. It embodies prototypicality, boundedness, orientation, plexity, scale proportions, part-whole re

Product-Service Systems: reviewing achievements and refining the research agenda

This special issue on Product-Service Systems: reviewing achievements and refining the research agenda shows the progress that has been made in the PSS field in the last decade, including various national and international research projects and companies' initiatives, important achievements and gaps at theoretical and practical levels. Most of the papers can be of interest to practitioners, compan
