Data volumes in communication networks increase rapidly. Further, usage of social network applications is very wide spread among users, and among these applications, Facebook is the most popular. In this paper, we analyse user demands patterns and content popularity of Facebook generated traffic. The data comes from residential users in two metropolitan access networks in Sweden, and we analyse mo

This thesis is focused on the early steps of a complex virus-cell interaction. The human adenovirus type 2 (HAdV-2) infects permissive cells, by first recognizing a protein of the immunoglobulin superfamily that serves as the Coxsackie and adenovirus receptor (CAR). This attachment step is mediated by the adenovirus fiber protein. Subsequently, in order to proceed to a tighter binding, the viral p

This study highlights the medical object as an approach to study illness narratives. The medical objects is discussed as a way in broadening the study of medicine and includes other dimensions than those related to the pharmacological treatment. The aim of the article is to use narratives about asthma to analyse the culture around body, illness and health in the mid-1900s. The study focuses on the

Popular Abstract in Swedish Makrofager återfinns i stort sett överallt i kroppen. De bildas från stamceller i benmärgen och cirkulerar i blodomloppet tillsammans med andra vita blodkroppar i form av monocyter, som kan vandra igenom blodkärlens väggar och vidareutvecklas till makrofager ute i vävnaderna. Makrofagen spelar en viktig roll i kroppens totalförsvar genom att vägleda och orkestrera immunMacrophages mediate innate immunity through release of cytokines, eicosanoids, reactive oxygen species as well as through phagocytosis and secretion of lysosomal enzymes. Regulation of lysosomal secretion in macrophages differs in several respects from release of specialized granules in other leukocytes. Lysosomal secretion is not dependent upon cytosolic calcium but is instead triggered by lysoso

This paper articulates drone warfare through a critical analysis of an actual drone operation and a study into its developing technologies. The first chapter moves through a discussion of the intervening role of the camera as described by Walter Benjamin and societal perspective of visual reproduction technology. This discussion then departs from the mechanical to the digital realm of realtime vid

The interest for the design of life environments for persons with dementia is growing stronger among architects, engineers, social scientists and those responsible for housing and health care planning. This development is connected to the enlarged group of people that become afflicted by this disease and to the fact that a safe environment is proved to be very important for their well-being as wel

A theory is presented for the service life of concrete exposed to frost action. It is based on a separation of the frost resistance problem in two parts. Part 1, that is only a function of the material itself, and which is expressed in terms of a critical water content, or a degree of saturation, which is a "fracture value" being almost independent of the external conditions (except for the lowest

The Relativistic Heavy Ion Collider (RHIC) has made it possible to study hadronic matter under unprecedented conditions in terms of temperature and energy density. Global variables are essential for the characterization of nuclear collisions at ultra-relativistic energies. The PHENIX experiment has several detectors which provide information about the global properties and hence the initial condit

Ion beam analysis techniques are now well established as research tools for a broad range of multidisciplinary scientific fields. The ability to focus an ion beam down to micrometer size has expanded and strengthened the capability of IBA techniques to a higher level. A new field “Nuclear microprobe (NMP) analysis” has been developed over the past decades, in which most IBA techniques are used and
