DNA- cationic amphiphile and DNA-cationic polymer systems were studied with respect to the intermolecular interactions, as well as structure and stability of formed complexes. The thesis is divided in two parts: one section is a summary and the other section contains five papers. The summary is organized as follows; Chapter 2 gives an overview on the behavior of polyelectrolytes in solutions with

In today s society, the foreground of deliberation-in politics, legislation, judicial decisions, even war is increasingly experienced by citizens as a mask for the working out of norms and institutions the precise nature of which eludes us. We are accustomed to looking behind every news item, often feeling that the real decisions are made by other people than those who seem to be in power, or that

In northern Sweden, Empetrum hermaphroditum Hagerup dominates the ground layer vegetation in post fire successions by suppressing other plant species. Previous studies suggest that this negative effect by E. hermaphroditum may be explained, at least in part, by the release of phenolic compounds, particularly batatasin-III, from foliage to soil. In this pilot study, we evaluated the effect of batat

The enzyme deoxyuridine 5’-triphosphate nucleotidohydrolase (dUTPase, EC 3.6.1.23) catalyzes the hydrolysis of dUTP to dUMP and pyrophosphate. The reaction suppresses misincorporation of uracil into DNA and provides dUMP for the de novo synthesis of dTTP. dUTPase is a widespread enzyme and the fact that many viruses encode a dUTPase of their own suggests the enzyme to be important for the viral li

Den socialdemokratiske politikern och författaren Atos Wirtanen var under Finlands fortsättningskrig engagerad i att rädda de judiska flyktingar som fanns i Finland. Artikeln beskriver och analyserar detta engagemang och frågar sig vad det var som drev Wirtanen i denna kamp.

In this paper, a passively clamped quasi-resonant DC link converter is analysed, implemented and evaluated in a battery charger application. Design expressions for selection of passive component values, based mainly on the specified maximum output voltage derivative and the duration of the zero voltage interval, are given. Design of the inductive components and selection of appropriate power semic

We apply causal loop diagrams (CLD) to picture how complex societal scenarios can be understood in terms of interdependent drivers and mechanisms between actors from the public and private sectors respectively. And we show how un-sustainable scenarios can be understood in terms of insufficient balancing feed-back in the system. We apply the methodology to picture such imbalances as funda- mental d
