Simultaneous measurements of the t (t) over bar, W+W-, and Z/gamma* -> tau tau production cross-sections using an integrated luminosity of 4.6 fb(-1) of pp collisions at root s = 7 TeV collected by the ATLAS detector at the LHC are presented. Events are selected with two high transverse momentum leptons consisting of an oppositely charged electron and muon pair. The three processes are separated u

This special issue of The Mental Lexicon contains a number of papers presented at a symposium at the Center for Languages and Literature, Lund University, on December 10, 2009. The interdisciplinary meeting brought together researchers from linguistics, psychology, and neuroscience in order to discuss different approaches to studying the complexities surrounding the modelling of word semantics.

The aim of the this study was to investigate the ozone dosage required to remove active pharmaceutical ingredients (APIs) from biologically treated wastewater of varying quality, originated from different raw wastewater and wastewater treatment processes. Secondary effluents from six Swedish wastewater treatment plants (WWTP) were spiked with 42 APIs (nominal concentration 1 mu g/L) and treated wi

This paper proposes that the maximum entropy principle can be used for determining the drop size distribution of hydrometeors. The maximum entropy principle can be applied to any physical systems with many degrees of freedom in order to determine a distribution of a variable when the following are known: 1) the restriction variable that leads to a homogeneous distribution without constraint and 2)

The purpose of this work is the development, identification and validation of a model for the simulation of a thermomechanical multistage production process chain for sheet steels. The process of interest consists of forming (in particular deep-drawing) followed by cutting and heat treatment. For the forming and cutting stages, the complete model is based in particular on a model for thermoelastic

Protein adsorption is a complex process that it controlled by several different mechanisms, for example: (i) electrostatic interactions between the protein and the surface, and (ii) between adsorbed proteins; (iii) dispersion interactions; (iv) hydration effects; and (v) structural rearrangements of the protein to balance conformational chain entropy with energetics. The aim of this study was to d

This paper presents a decomposition strategy applicable to DAE constrained optimization problems. A common solution method for such problems is to apply a direct transcription method and solve the re- sulting nonlinear program using an interior-point algorithm. For this approach, the time to solve the linearized KKT system at each iteration typically dominates the total solution time. In our propo

Background: In soils contaminated by hydrophobic organic compounds, the concentrations are less indicative of potential exposure and distribution than are the associated chemical activities, fugacities and freely dissolved concentrations. The latter can be measured by diffusive sampling into thin layers of polymer, as in, for example, solid phase micro-extraction. Such measurements require equilib

Popular Abstract in Swedish I avhandlingens fokus står förhållandena på Kosta glasbruk under perioden 1820-1880. Glasbruket som grundades år 1742 är en av de många mindre svenska bruksbildningarna. Under hela undersökningsperioden måste glasbruket ses som förhållandevis litet med som mest ett 80-tal hushåll direkt knutna till glasbrukets industriproduktion. Glasbruket hade liksom flertalet svenskaThis thesis focuses on the circumstances at the glassworks of Kosta during the years 1820-1880. The glassworks founded there in 1742 was but one of many small Swedish rural works. Throughout the period in question, the glassworks can be seen as a small-scale factory with about 80 households directly engaged in industrial production. Like the rest of the glass industry, the glassworks at Kosta deve

Climate change and disasters are among today’s most pressing issues. The damage caused by the world-wide increase in disasters is staggering, with the urban poor being most at risk. Disasters make their al-ready precarious living conditions worse, creating a vicious circle of poverty. More and more attention has thus been given to the need to address changing climatic conditions and disaster risk

Ethanol production by the yeast Saccharomyces cerevisiae from dilute acid lignocellulose hydrolyzate was studied with the aim to improve fuel ethanol production. Specifically, the problem of inhibition was addressed. Lignocellulose hydrolyzate contains not only sugars, but also several compounds, such as furfural and 5-hydroxymethyl furfural (HMF), which can inhibit yeast growth and ethanol produc

The interdisciplinary symposium ”Microstructures of Learning: Novel methods and approaches for assessing structural and functional changes underlying knowledge acquisition in the brain” took place on May 23, 2014 in Lund, Sweden. The cross-disciplinary meeting brought together researchers from linguistics, psychology, physics, chemistry, and neuroscience in order to discuss how knowledge, in part

Popular Abstract in Swedish Detta är en av de få större statsrättsliga studierna i Sverige på senare år. Vad som analyseras i boken är inte rättsläget beträffande någon enskild rättighet utan de skyddsmekanismer för de medborgerliga rättigheterna som finns i ett antal västliga rättssystem. Förutom Sverige behandlas Danmark, Norge, Finland, Tyskland, Frankrike, Storbrittanien och USA. Särskilda kapConstitutional Protection of Human Rights means something else than international protection, first and foremost since it is exercised at a national level. This protection may be excercised by courts or by special mechanisms of protection within the legislative process. However, if this protection of the basic rights of the individuals is to be a strong one, it is likely to limit the freedom of ac

The paper analyses the behaviour of convergence/divergence primarily within Western Europe and the OECD in relation to market integration and to major technological shifts such as the second and the third industrial revolution. It also relates the behaviour to traditional growth theory and endogenous growth theory as well as to historical generalisations based on structural analysis. The empirical

Hepatitis C virus (HCV) belongs to the Hepacivirus genus in the Flaviviridae family. Among the least known viral proteins in this family is the nonstructural protein NS4B, which has been suggested to be a part of the replication complex. Hydrophobicity plots indicate a common profile among the NS4B proteins from different members of the Flaviviridae family, suggesting a common function. In order t
