Popular Abstract in Swedish Konflikter och sexuellt urval under pollenkonkurrens Naturens många fantastiska färger och former har till stor del skapats av det sexuella urvalet, det vill säga selektionstryck som skapas av konkurrens och val, som uppstår till följd av att djur och växter fortplantar sig. Det var Darwin som 1871 presenterade teorin om det sexuella urvalet i ett försök att förklara vThe incidence of sexual selection in plants is today acknowledged, however, just as in animals, evolution and maintenance of mate choice is gravely underexplored. Moreover, the potential for sexual conflicts to occur in plants has only been assessed empirically to a very limited degree. Using the hermaphroditic annual herb Collinsia heterophylla, I looked deeper into the role of pollen-pollen comp

This paper introduces the idea that location based pervasive games can be used to make mobility training for visually impaired children more fun. The user centred development process which has been carried out in collaboration with both visually impaired children and rehabilitation staff is described and we present a novel game concept which combines locative play, sound traces and a physical catc

This paper studies regional museum, archives and arts education commissions of the Region of Scania, reformed in 2009, from a policy analysis perspective. It describes the background, design and implementation of the new policy and analyses its effects. The paper gives detailed information on the complexities of policy tool design and implementation, and discusses it in the light of regional gover

We present a multiuser synchronization scheme for tracking the mobile's uplink time and frequency offsets. It uses the redundancy introduced by the cyclic prefix and does not need additional pilots. We show performance results of an orthogonal frequency division multiplexing (OFDM)-based radio interface based on the universal mobile telecommunication system (UMTS) parameters. For a UMTS-typical mo

We present rational rate k/n punctured convolutional codes (n up to 8, k=1, ···, n-1, and constraint length ν up to 8) with good performance. Many of these codes improve the free distance and (or) weight spectra over previously reported codes with the same parameters. The tabulated codes are found by an exhaustive (or a random) search

Objectives: On account of the increasing worldwide problems associated with overweight and obesity, the aim of the present study was to examine BMI change over 5 years in relation to different lifestyle-, demographic- and psychosocial work-related factors. METHODS: A cohort of 9913 persons responded to an identical survey in 2000 and 2005. BMI change over the period was examined in relation to gen

Summary and further discussion of the main thesis in the authors dissertation (Den gotiske labyrint. Middelalderen og kirkerne i Danmark; The Gothic labyrinth. The Middle Ages and the churches in Denmark, 1993). Monasteries in Denmark, their forundation dates, numbers, size, design, decoration and fixtures are used as a source to show when the power of the church was built up, changed and broken d

OBJECTIVE: The initiating events in the onset of pancreatitis are poorly understood. Possible candidates may be endogenous ligands, acting on receptors within ductal, acinar or stellate cells, which have previously been shown to cause a systemic inflammatory response syndrome. The aim of this study was to investigate whether acute pancreatitis could be induced by heparan sulphate (HS)infused into

The article analyses the role of the historical dimension in official Swedish debate, with a focus on the Swedish government's Living History information project on the Holocaust
