In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. In common practice the active MASW method is implemented using a sledgehammer source and a linear receiver spread. This method is lim

Autoantibody-mediated diseases comprise a heterogeneous group of disorders in which the pathogenic potential of autoantibodies has been clearly demonstrated. In general, their treatment relies on the long-term use of systemic corticosteroids and other immunosuppressants that are associated with considerable adverse reactions. EndoS, an endoglycosidase derived from Streptococcus pyogenes, specifica

I dagens samhälle kämpar företag för att höras och synas i det överflöd av information som finns tillgänglig. Ett särskiljande kännetecken har därmed blivit ett mycket viktigt kommunikationsmedel för företag. I detta kännetecken ligger ofta ett betydande värde i form av goodwill och image och attityd hos förbrukarna. Inte sällan är det hela koncept som förmedlas i ett komplicerat byggande av relat

Fluxes of methane, CH4, were measured with the eddy covariance (EC) method at a small boreal lake in Sweden. The mean CH4 flux during the growing season of 2013 was 20.1 nmol m−2 s−1 and the median flux was 16 nmol m−2 s−1 (corresponding to 1.7 mmol m−2 d−1 and 1.4 mmol m−2 d−1). Monthly mean values of CH4 flux measured with the EC method were compared with fluxes measured with floating chambers (

Popular Abstract in English Nowadays road, air and sea transport activities around the world are almost completely dependent on finite and polluting oil fuels. Biofuels are fuels produced from biomass which can be used to substitute gasoline and diesel in cars, busses and (soon) planes. Where oil was created millions of years ago and is soon reaching its limit, biofuels are renewable fuels which cThe dependency of transport on oil fuels is responsible for risks of energy supply security, and local, regional and global environmental problems, including the emission of greenhouse gases affecting the Earth’s climate system. Biofuels attracted considerable attention in recent years as a solution to these problems. However, the deployment of biofuel technologies poses as many opportunities to b

We analyse biological switches with the aid of computers and the Gillespie method, a stochastic solver. Stochastic calculations can lead to spontaneous switches which are, in part, determined by a subset of the parameters. In a deterministic description this is hidden. Initial analysis using a deterministic description of the system will reveal that by applying certain constraints on the system we

Theoretical option prices can be computed using several different pricing models which make numerous assumptions about the markets and the underlying asset. Depending on those assumptions, the models have different strengths and weaknesses which make them more suited to a specific type of market. This study evaluates six different pricing models implemented in MATLAB, and introduces a combined mod
