2. 1. Impartial Games and Recursive Functions

   Author : Urban Larsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Algorithmically undecidable; Beatty sequences; Blocking maneuver; Cellular automaton; Comply maneuver; Complementary sequences; Dictionary process; Dual game; Game complexity; Game convergence; Game reflexivity; Heap game; Impartial game; Invariant subtraction game; Move-size dynamic; Nim; P-equivalence; Rule 110; Splitting sequences; *-operator; Subtraction game; Take-away game; Turing complete; Wythoff Nim; Turing complete;

   Abstract : Interest in 2-player impartial games often concerns the famous theory of Sprague-Grundy. In this thesis we study other aspects, bridging some gaps between combinatorial number theory, computer science and combinatorial games. READ MORE

4. 2. Boundary values of plurisubharmonic functions and related topics

   Author : Berit Kemppe; Urban Cegrell; Anders Fällström; Alexander Raskovskii; Umeå universitet; []

   Abstract : This thesis consists of three papers concerning problems related to plurisubharmonic functions on bounded hyperconvex domains, in particular boundary values of such functions. The papers summarized in this thesis are:* Paper I Urban Cegrell and Berit Kemppe, Monge-Ampère boundary measures, Ann. Polon. Math. READ MORE

5. 3. Approximation and Subextension of Negative Plurisubharmonic Functions

   Author : Lisa Hed; Urban Cegrell; Frank Wikström; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex Monge-Ampère operator; Approximation; Plurisubharmonic function; Subextension; MATHEMATICS; MATEMATIK;

   Abstract : In this thesis we study approximation of negative plurisubharmonic functions by functions defined on strictly larger domains. We show that, under certain conditions, every function u that is defined on a bounded hyperconvex domain Ω in Cn and has essentially boundary values zero and bounded Monge-Ampère mass, can be approximated by an increasing sequence of functions {uj} that are defined on strictly larger domains, has boundary values zero and bounded Monge-Ampère mass.

6. 4. Glutathione during stress in man

   Author : Urban Fläring; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Glutathione, a tripeptide (gamma-glutamyl, -cysteinyl, -glycine), is quantitatively the most important antioxidant in man, protecting cells from the toxic effects of reactive oxygen species (ROS). These highly reactive molecules cause tissue damage and are produced at high rates during critical illness including sepsis [1-4]. READ MORE

7. 5. Management of Sustainability in Construction Works

   Author : Urban Persson; Byggproduktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction works; assessment model; sustainability; Management;

   Abstract : The present global environmental condition is a consequence of the increasing consumption of natural resources whose depletion exceeds what is physically possible to sustain in the long term. The construction sector is a considerable contributor to this resource depletion and sustainability is adopted in the form of the theory of ecological modernization. READ MORE
