1. 1. Infinite dimensional holomorphy in the ring of formal power series : partial differential operators

   Författare :Henrik Petersson; Andrei Khrennikov; Sean Dineen; Växjö universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Infinite dimensional holomorphy; Formal power series; Fourier-Borel transform; Paley-Wiener theorem; Fischer decomposition; Fischer pair; Fock space; Cauchy-Problem; Kergin operator; PDE-preserving; Pseudo-differential operators.; MATHEMATICS; MATEMATIK;

   Sammanfattning : We study holomorphy in the ring of formal power series in an infinite number of variables. Thus we restrict our study to (infinite dimensional) holomorphy on sequence spaces and we show that we obtain a rich theory without requiring any topological structure on the domain space. We make a comprehensive PDO-study for the spaces under consideration. LÄS MER

3. 2. Representing Cultural Diplomacy : Soft Power, Cosmopolitan Constructivism and Nation Branding in Mexico and Sweden

4. 3. Material migration in tokamaks: Studies of deposition processes and characterisation of dust particles

   Författare :Armin Weckmann; Marek Rubel; Per Petersson; Daniel Primetzhofer; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tokamak; fusion; plasma; material migration; particle transport; TEXTOR; PWI; plasma-wall interaction; plasma facing components; PFC; PFM; plasma facing materials; ALT limiter; MoF6; tracer experiment; molybdenum hexafluoride; future energy source; fuel retention; deuterium retention;

   Sammanfattning : Thermonuclear fusion may become an attractive future power source. The most promising of all fusion machine concepts is the tokamak. Despite decades of active research, still huge tasks remain before a fusion power plant can go online. One of these important tasks deals with the interaction between the fusion plasma and the reactor wall. LÄS MER

5. 4. Fluoride concentration in plaque and saliva and its effects on oral ecology after intake of fluoridated milk

   Författare :Kristina Engström; Svante Twetman; Lars G Petersson; Göran Dahllöf; Umeå universitet; []
   Nyckelord :children; enamel; demineralisation; fluoride; lactic acid; laser fluoroscense; milk; plaque; saliva; salivary bacteria; odontologi; Odontology;

   Sammanfattning : According to WHO, the addition of fluoride to milk could be considered as an alternative to water fluoridation for community-based caries prevention in childhood. School-based schemes in developing as well as industrial countries have demonstrated substantial benefits on oral health, but there are limited data available on the local events in the oral cavity after consumption of fluoridated milk.

7. 5. Näten på Limhamn : Sociala relationer i ett lokalsamhälle 1870-1914

   Författare :Johan Lundin; Historia; []
   Nyckelord :HUMANIORA; HUMANITIES; Religion; Popular movements; Labour movement; Class; Paternalism; Family history; Social capital; Social networks; Contemporary history circa 1800 to 1914 ; Modern historia ca. 1800-1914 ; Sociala nätverk;

   Sammanfattning : The aim of the study is to examine, using the social networks as a starting-point, the way a local community is constructed in a specific historical context, namely the industrial community of Limhamn in southern Sweden at the time of the Industrial Revolution 1870-1914. In 1870 the Skånska Cement Company initiated a large-scale extraction of limestone in the area and soon had cement works built in the village, making Limhamn undergo a rapid urbanization. LÄS MER
