YBa2Cu3O7-δ (YBCO) with low RF losses has been successfully deposited onto lithium niobate (LNO) to improve the performance of electrooptic Mach-Zender modulators. Epitaxial, c-axis oriented superconducting YBCO thin films have been grown on X-cut LNO single crystals with a yttria-stabilized zirconia (YSZ) buffer layer by RF magnetron sputtering. This buffer layer is needed to obtain good supercon

A common method for comparing the result of different global circulation models (GCMs) under different emission scenarios is to study global climate response variables, such as mean temperature. An interesting alternative measure of climate sensitivity is to study the biosphere’s response to the different climate scenarios. The Lund-Postdam-Jena (LPJ) global vegetation model and its extension LPJ-

Popular Abstract in Swedish Vid typ 1 diabetes har patienten ingen egen insulinproduktion, utan måste tillföra insulin via injektioner i underhudsfettet. Insulinbehovet är inte konstant, utan varierar beroende på olika faktorer, t.ex. fysisk aktivitet och födointag. Eftersom det är svårt att alltid rätt förutsäga vilken insulinmängd man behöver, varierar blodsockret (blodglukos) mer hos en insulinHypoglycaemia is an acute complication to insulin-treatment in type 1 diabetes mellitus, which affects many physiological parameters, deteriorates the cognitive function, and may lead to death. The aim of this thesis was to study nerve function, cognitive function and cerebral blood flow during and after hypoglycaemia in healthy subjects and to study certain aspects of a fall in blood glucose in p

The current Status of 94 liehen species, of which 83 are extracted from the Swedish Red Data list, has been investigated in Skåne, the southernmost province of Sweden. The results, including over 1000 field records, indicate a retreat connected with environmental problems, especially air pollution. 41 species have disappeared, 16 species are considered endangered, 11 species are considered vulnera

The dissertation is an attempt to understand the genesis of Hegel's thought on two levels: within a social and historical setting and within an intellectual setting. In the one case the relation between human thought and the social context from which it springs is thematized, in the other an attempt is made to reconstruct a development within the history of ideas. These two perspectives are integr

A new system to categorize the content of group diaries is developed and tried out in 12 PBL groups. The theoretically derived and preformed main categories were Boundary manage¬ment, Transformational realms, Awareness of organizational contexts and temporal perspectives. After analysis it is concluded that it may be a more fruitful way to proceed through reading and analyzing the diaries as narra

The traditional notuion of democracy being anchored in discussions among citizens is highlighted. The chapter makes the claim that while civic talk is central to the life of democracy, there are many socio-cultural factors that impede poitical discussion. Also, while formal deliberation is important, even the free-flowing, messy and unpredictable converations of everyday life can give rise to the
