The Haemophilus surface fibril (Hsf) is an unusually large trimeric autotransporter adhesin (TAA) expressed by the most virulent strains of H. influenzae. Hsf is known to mediate adhesion between pathogen and host, allowing the establishment of potentially deadly diseases such as epiglottitis, meningitis and pneumonia. While recent research has suggested that this TAA might adopt a novel 'hairpin
Context. Determining elemental abundances of bulge stars can, via chemical evolution modeling, help to understand the formation and evolution of the bulge. Recently there have been claims both for and against the bulge having a different [α/Fe] versus [Fe/H] trend as compared to the local thick disk. This could possibly indicate a faster, or at least different, formation timescale of the bulge as
The causes and consequences of the financial crises in the Nordic countries in the early are examined and lessons from this episode are extracted. The focus is on the boom–bust episode in Finland, Norway and Sweden as these three economies went into a deep recession. The lessons from the Scandinavian experience are organised under three headings: (i) how to liberalise without causing a boom–bust c
Partially Premixed Combustion (PPC) is a promising combustion concept for future IC engines. However, controllability of PPC is still a challenge and needs more investigation. The scope of the present study is to investigate the ignition sensitivity of PPC to the injection timing at different injection pressures. To better understand this, high-speed shadowgraphy is used to visualize fuel injectio
We point out that official forecasts of output dynamics are crucial to the assessment of cyclically adjusted budget balances, and provide evidence that in some euro-area countries biased forecasts have played a thus far neglected role in generating excessive deficits. We suggest that the forecast bias may be politically motivated, and that forecasts produced by an independent authority would be be
Inflation targeting is the monetary strategy of all EU member states; whether in the euro area, the two euro-outs, Sweden and the United Kingdom. The latter are now faced with two alternatives to achieve price stability: either remain outside the euro area or join it as full-fledged members. This paper examines this policy choice starting from the views of Knut Wicksell, who considered it in his 1
Aims to shed light on the choice of exchange rate system facing Finland and Sweden by using theories of optimum currency areas as framework. Review of theories dealing with optimum currency areas; Relationship of Finland and Sweden and between these two countries and other industrial countries; Advantages of a Finnish-Swedish monetary union over membership within the European Monetary Union.
In September 1931, Sweden became the first country to make the stabilization of the domestic price level the official goal of its monetary policy, actually the only country that so far has adopted such an explicit price level target. Starting from the issues and concepts familiar from research and policy experience of inflation targeting - as contrasted to price level targeting - this paper examin
We study common features in the income velocity of money, income, and interest rates for Canada, the U.S., the U.K., Sweden and Norway using annual data from 1870. The recently developed and refined techniques of testing for cointegration are employed.The evidence suggests there is a unique long-run relationship in velocity but not in income and interest rates. Moreover, we find that only a model
In this study, the recent literature on the integration of fiscal and monetary policy is used to examine the suspensions and resumptions of currency convertibility in Sweden during the period 1668-1931. We demonstrate that urgent demands for financing of war expenditures forced the Swedish Riksbank to abandon convertibility of its notes in all cases of suspensions prior to 1914. We argue that the
