Azimuthal asymmetries of the hadronic final state in deep inelastic scattering at HERA provide the opportunity to study the helicity of the interacting particles. We present a theoretical overview of the origin of these effects up to leading order in the strong coupling constant, $alpha_s$. A review of previous measurements is given and the results are discussed. The effects of the intrinsic trans

Popular Abstract in Swedish Sedan årtionden tillbaks finns en stor mängd klorerade organiska miljögifter spridda i vår miljö (t ex DDT, PCBer och dioxiner). Djur får i sig miljögifterna främst med födan och eftersom dessa ämnen som regel är svårnedbrytbara och inte kan omsättas i kroppen i någon större omfattning leder detta till att de istället lagras upp i djuren, framför allt i fettvävnaden. EtChlorinated fatty acids (ClFAs) are the major contributors of extractable, organically bound chlorine in fish lipids. A known anthropogenic source of ClFAs is chlorine bleached pulp production. Additional anthropogenic sources may exist, e.g., chlorine-containing discharge from industrial and house-hold waste and they may also occur naturally. ClFAs have a wide geographic distribution. They have,

Nitrogen removal wetlands are constructed in agricultural areas as a measure to reduce the amount of non-point source nitrogen that reaches coastal areas. Methane and nitrous oxide, two greenhouse gases, are produced under anaerobic conditions and an increased amount of waterlogged areas will therefore increase the potential emission of these gases. The question has arisen: Are we solving one envi

Diabetes is a heterogeneous disease influenced by both environmental and genetic factors. Maturity-onset diabetes of the young (MODY) is considered as a subform of Type 2 diabetes, which is inherited in an autosomal dominant fashion and expressed at childhood or early adult life. The aims of the study was to a) search for susceptibility loci for Type 2 diabetes in 26 Finnish families with late-ons

Software inspection has proven to be an effective way to increase the quality of software products. A new reading technique suggested for software inspection, usage-based reading (UBR), has been tested in previous studies, where it showed good defect detection efficiency during inspection of design documents. This study addresses the question whether this is true also for inspections of requiremen

Corporate mergers and acquisitions (M&A) have established themselves as prominent tools for corporate strategy. Consequently more and more organizations direct their attention towards the potential benefits of an M&A and the problems of leveraging these potentials. Managing information systems (IS) integration in M&A means understanding the dynamic relationship between IS integration a

There is a growing body of evidence that the parents of trauma-exposed children report posttraumatic stress symptoms whether they are directly exposed to the same trauma as the child or not. The parents’ symptoms also correlate with the child’s self-reported symptoms – although not as strongly as some might expect. There is a widespread assumption that anxious parents model and reward anxious beha
