In this note we discuss some aspects of the peakon-antipeakon interaction for the Camassa-Holm equation.

Artikeln undersöker människors förhållningssätt till uppslagsverk och encyklopedier i ett livshistoriskt perspektiv under en period när encyklopedier har genomgått dramatiska förändringar. En frågelista som skickats till fasta så kallade meddelare knutna till Folklivsarkivet i Lund har använts som metod. Svaren har analyserats med hjälp av posthumanistisk teori. Analysen visar de sätt som tryckta Encyclopaedias are artefacts that both define and are defined by the culture in which they are produced and used. Encyclopaedias mirror the time of their creation, at the same time as understanding and use of encyclopaedias is tied to both time and space. From the 19th century until the present day encyclopaedias have changed from exclusive and costly Collections of books kept mainly in libraries

To examine the potential influence of terrestrially derived DOM on the Baltic Sea, a year-long study of dissolved organic matter (DOM) was performed in three river catchments in Sweden. One catchment drains into the Bothnian Sea, while two southern catchments drain into the Baltic proper. Dissolved organic carbon (DOC) concentrations were positively correlated with discharge from forested catchmen

We provide a new proof of Volberg's Theorem characterizing thin interpolating sequences as those for which the Gram matrix associated to the normalized reproducing kernels is a compact perturbation of the identity. In the same paper, Volberg characterized sequences for which the Gram matrix is a compact perturbation of a unitary as well as those for which the Gram matrix is a Schatten-2 class pert

Base cation weathering (BCw) rate is one of the most influential yet difficult to estimate parameters in the calculation of critical acid loads of nitrogen (N) and sulfur (S) deposition for terrestrial systems. Only the clay correlation-substrate method, a simple empirical model, has been used for estimating BCw rates for forest ecosystems in the conterminous USA and may not be suitable for applic

The end of the Cold War marked the ending of an era of a bipolar rivalry, but it also brought about a new set of challenges for policymakers and national intelligence agencies. One of these new challenges is sharing sensitive information with states and actors outside comfortable alliances, whilst countering a myriad of asymmetric, often low-level type of security threats. Implementation of intell

The aim of this thesis is to examine the effect changes in oil, coal, natural gas and electricity prices have on the stock market. Using a linear regression approach, we study nine market sectors in Sweden and Norway from January 1996 to November 2010. Previous research has in some cases shown that oil prices have a impact on the stock market. We expand this research by including more energy varia

This paper investigates the exchange rate movements for EUR/USD, EUR/SEK and EUR/NOK using an OLS regression. Movements are tested against traditional and nontraditional explanatory variables for exchange rate movements. Traditional variables consists of current account, inflation, productivity and interest rate differentials while the nontraditional are equity returns and risk appetite. Results i

This paper uses an autoethnographic approach to analyze the work of an entrepreneur on a the new venture, AirOhMail, in regards to intellectual property and product protection. By comparing AirOhMail with the failed start-up, SurPrise - both companies attempting to commercialize the same product - this paper demonstrates how a low-level innovation product can better achieve success in the start-up

We leverage U.S. county-day temperature variation combined with daily time use data to examine the effect of temperature on the timing of work. We find that warmer (colder) temperatures increase (decrease) working time during the night and decrease (increase) working time in the morning. These effects are pronounced among workers with increased bargaining power, flexible work schedules, greater ex

This essay explores artistic expressions dealing with themes of nuclear weapons and radioactivity in Israel/Palestine. It brings together a variety of different sources representing critical interventions in the debate on Israeli nuclear weapons, particularly their opacity, and their absent presence in the country and in wider political debates. The artistic pieces demonstrate how the reactor is m

Nordic animation has experienced an intense development through digitalization which has led to wider proliferation and increased versatility. This chapter maps the development of Nordic animation in the 21st Century from feature film tentpoles to independent shorts and the thematic diversity it constitutes.

If hedonism is taken to be the view that all and only pleasures are the bearers of intrinsic value whilst also saying that complex things, such as states of affairs, can be ascribed intrinsic value, the hedonic thesis seems to be contradictory. Furthermore it has been argued that the hedonic thesis is inconsistent in its treatment of the notion of intrinsic value in another sense, namely that if t
