The aim of this study was to reconstruct river flow to the Baltic Sea using data from different periods during the past thousand years. A hydrological model coupled to simulations from climate models was used to estimate river flow. A "millennium" simulation of past climate from the ECHO-G coupled atmosphere-ocean global climate model provided climatological inputs. Results from this global model
Aortic arch repair, is a surgical challenge irrespective of which technique is applied. While open surgical repair is a major trauma and a technically difficult procedure that many elderly patients tolerate poorly, the branched and fenestrated stentgrafts remain complex to implant safely. Hybrid procedures combine some of the advantages of both open and endovascular techniques but also many disadv
Popular Abstract in Swedish Ekonomisk teori delar ofta in ekonomin i olika tidshorisonter, som till exempel kortsikt, medelfristigsikt och långsikt. Det är ofta enklare att empiriskt studera modeller med många tidshorisonter i frekvensdomänen än i tidsdomänen eftersom varje horisont representeras av en specifik frekvens eller ett band av frekvenser. Denna avhandling använder wavelet analys för attEconomic theory commonly distinguishes between different time horizons such as the short run and the long run. Models with many time horizons are easily studied in the frequency domain, because the various time horizons are associated with a particular frequency or band of frequencies. This dissertation studies wavelet methods to analyze time series. Wavelet transforms combine time and frequency r
Environmental change may affect predator-prey interactions in lakes through deterioration of visual conditions affecting foraging success of visually oriented predators. Environmental change in lakes includes an increase in humic matter causing browner water and reduced visibility, affecting the behavioural performance of both piscivores and prey. We studied diurnal patterns of prey selection in p
We present a new method for manufacturing complex-valued harmonic morphisms from a wide class of Riemannian Lie groups. This yields new solutions from an important family of homogeneous Hadamard manifolds. We also give a new method for constructing left-invariant foliations on a large class of Lie groups producing harmonic morphisms.
Increased red cell distribution width (RDW) has been related to poor prognosis in patients with cardiovascular disease, and is a predictor of cardiovascular mortality in the general population. The purpose of the present study was to investigate if RDW is associated with increased incidence of stroke and its subtypes in individuals from the general population.

Let H be a Hilbert space of analytic functions with multiplier algebra M(H), and let M = {(f, T(1)f, ... ,T(n-1)f) : f is an element of D} be an invariant graph subspace for M(H)((n)). Here n >= 2, D subset of H is a vector-subspace, T-i : D -> H are linear transformations that commute with each multiplication operator M-phi is an element of M(H), and M is closed in H-(n). In this paper we investi
The acquisition of multispectral x-ray images and the treatment of such data are essential for understanding many devices that we encounter in everyday life. Examples include computerized tomography in hospitals and scanners at airports. X-ray devices remain impractical for undergraduate laboratories because of their considerable cost and the risk of exposure to ionizing radiation. One way to acqu
This paper introduces a novel approach to building virtual laboratories of embedded control systems using TrueTime and Easy Java Simulations. TrueTime is a freeware MATLAB/Simulink based tool commonly used to simulate embedded control systems. Easy Java Simulations is a popular authoring tool that facilitates the creation of pedagogical simulations. According to the proposed approach, authors use
Since the 1990s, vigorous debate concerning a number of key issues has taken place within the study of Chinese nationalism. Scholars have tended to differentiate between diverse types of nationalism. For example, many studies distinguish between a malign nationalism on the one hand and a benign patriotism on the other. The strongest evidence for such a distinction can be found in survey research,
The phase behavior of systems containing sodium alkyl polypropylene oxide sulfate with equimolar ratio of polypropylene oxide ammonium chloride was determined as a function of salt concentration and alkane carbon number at ambient temperature. Visual inspection as well as cross polarizers were used to detect anisotropy. Solubilization ratios for oil and brine in the middle phases were measured and
The structural characteristics of Ba-Fe double hydroxides were studied by various methods, such as scanning electron microscopy (SEM), energy dispersive X-ray (EDX) fluorescence and X-ray absorption spectroscopies (XAS). It was verified that under hyperalkaline conditions (using 10 M or 20 M NaOH solution for precipitating the substances) layered double hydroxides could be prepared and the structu
Background: Heparin Binding Protein (HBP) is released to blood circulation from activated neutrophils in bacterial infections. It is a potential inducer of vascular leakage and precludes the development of septic shock. Filgrastim induces the production of new neutrophils and modulates their bacterial-killing activity. We evaluated the effect of filgrastim on HBP -concentrations in critically ill
Chronic myeloid leukemia (CML) is caused by the transformation of a primitive hematopoietic cell by the BCR/ABL1 fusion gene that is formed through the chromosomal translocation t(9;22). CML is currently successfully treated with tyrosine kinase inhibitors targeting the ABL1 kinase domain. However, the CML stem cells are insensitive to this drug and a large fraction of patients will have relapse f
Despite efforts to stimulate the dissemination of green purchasing practices, their uptake in business and industry has so far proven limited. Reasons for the limited progress remain largely unclear. One factor explored in this thesis, is the role of information in the operationalization and dissemination of green purchasing in organizations and supply chains. The importance of knowledge and infor
