In conjugated polymers the concept of spectroscopic units belonging to different spatial segments of the chain, which are responsible for the spectroscopic properties of the polymer, has been used to explain the spectral heterogeneity and the excitation migration by (Forster type) hopping transfer. In the present work we study the possible mechanism of segmentation of polythiophene into spectrosco

Abstract Itch accompanies most inflammatory skin diseases but may occur as a solitary sensation in otherwise normal skin. Chronic itch often requires combined treatments but some cases remain therapy resistant. Complementary medicine is becoming increasingly popular among patients. Acupuncture is the oldest and most well-studied alternative option with evidence-based effect on pain. This article s

The S.T.A.R. Design Studio (Space and Terrestrial Architectural Research) studies pre-industrial habitats in i.a. Tanzania, and develops design concepts for future habitats in space in cooperation with Johnson Space Centre, Houston, Texas. In both cases our studies focus on "extreme" circumstances. Perhaps studying the conditions of a crew sealed in a capsule can better prepare us for the problems

In this chapter two examples are presented were the Swedish legislator built market mecanisms into the unemployment insurance system and the pension system. The two market mecanisms were designed to make trade unions with high unemployment show restraint in collective wage bargaining and to make elderly people chose two postpone retirement. The aim of the legislation was to make the opposite choic

Different societies regulate differently. Historically, social evolution has often been connected to technological innovations. The combustion engine took a central position in what later became known as the industrialized society, an urbanizing era of factories and production, on its hand following on the rural society tied to agriculture and trade. With each type of society comes a specific type

Packaging has great potential to contribute to sustainable development. This is due to its primary role to protect products. This paper reports on how Swedish consumers perceive and select food packages in general, and how environmental aspects of conventional and organic food packaging are perceived in particular. The study is based on a consumer survey. The findings indicate that contrary to res

This thesis focuses on the era of early film, with the aim to address an almost forgotten film language. Three aspects have been taken into account—variable frame rates, suppressed sound and hearing, and projection speeds—to analyze several examples of film to ascertain the techniques used by early filmmakers. I have also applied my findings of the techniques of yesteryear to contemporary films th

Theories lead to contradictory hypotheses regarding the determinants of vertical and horizontal IIT. Hence, in order to be able to investigate the country-specific determinants of VIIT and HIIT, it is important to empirically delimit the two from each other. This study employs the traditional Grubel and Lloyd measure of intra-industry trade, unadjusted for trade imbalance, and the method developed
