  • The fractal spatial distribution of pancreatic islets in three dimensions : a self-avoiding growth model

    Jo, Junghyo; Hörnblad, Andreas; Kilimnik, German; Hara, Manami; Ahlgren, Ulf; Periwal, Vipul (2013)
    The islets of Langerhans, responsible for controlling blood glucose levels, are dispersed within the pancreas. A universal power law governing the fractal spatial distribution of islets in two-dimensional pancreatic sections has been reported. However, the fractal geometry in the actual three-dimensional pancreas volume, and the developmental process that gives rise to such a self-similar structure, has not been investigated. Here, we examined the three-dimensional spatial distribution of isl...

    Boken som medium

    Pelle, Snickars (2012)
    I slutet av september 2011 presenterade Amazon ett ny slags surfplatta, Kindle Fire. Till skillnad från företagets tidigare läsplattor, som (nästan) enbart handlat om läsning på skärm, var detta en Kindle som behärskade hela det samtidsmediala spektrat. Under ledning av Amazons VD Jeff Bezos var själva lanseringen av Kindle Fire visserligen en ganska platt historia. Bezos är ingen estradör och en föga karismatisk företagsledare med än mindre publikreaktioner gör inte någon succé – eller som e...

    Kreativitet : En studie av matematikuppgifterna i PISA 2003

    Brodin, Andreas (2009)
    Forskning har visat att uppgifter i prov inverkar på vad elever lär sig genom deras förväntningar på vad testet ska innehålla (Virta, 2004). Boesen (2006b) konstaterar att uppgifter i nationella prov påverkar lärares undervisning vilket indirekt också bör inverka på vad elever lär sig. Lithner (2008) menar att det finns risk att en elev som använder ett imitativt resonemang i alltför hög grad vid lösning av matematikuppgifter får sämre matematikkunskaper. Genom att som lärare förse eleven med...

    Creation of identity and socializing in online games : The molding of a digital identity

    Schliemann, Erik (2013)

An aspect of this radically evolving technology thatexhibits strong possibilities for altering or producing identities is the rapidly growingonline game genre MMOG (Massive Multiplayer Online Game) which isentertainment that millions of people all over the globe engage in daily. Thisrelatively new pl...
