The Components of Well-Being Among Older Persons : A Longitudinal Perspective

Popular Abstract in Swedish Två svenska longitudinella kohort studier är basen för denna avhandling som analyserar välbefinnandet hos yngre äldre och äldre äldre. LUND 80+startade 1988, när deltagarna i undersökningen var 80 år gamla (N=212) med årliga uppföljningar tills alla avlidit. DALBY 67+ undersökningen började 1969, när deltagarna var 67 år gamla (N=192) och har följts till 92 års ålder. BTwo Swedish longitudinal cohort studies form the basis for this thesis that examines the components of well-being from young old to oldest old. The Lund 80+ cross-sequential design began in 1988 when participants were 80-years old (N=212) and follows them annually until all are deceased. The Dalby 67 began in 1969 when participants were 67 years old (N=192) and continued until they reached 92 year

A flexible CO2 targeting regime

According to EU regulations, CO2 emissions capped by the EU emission trading system must decline by 1.74 percent per year from 2013 and onwards. This paper argues that it is necessary to allow short term fluctuations in emissions in order to avoid unnecessary volatility in the real economy. An analysis of emissions data from the European Union and the United States reveals systematic fluctuations

Comparing the xylose reductase/xylitol dehydrogenase and xylose isomerase pathways in arabinose and xylose fermenting Saccharomyces cerevisiae strains

Background: Ethanolic fermentation of lignocellulosic biomass is a sustainable option for the production of bioethanol. This process would greatly benefit from recombinant Saccharomyces cerevisiae strains also able to ferment, besides the hexose sugar fraction, the pentose sugars, arabinose and xylose. Different pathways can be introduced in S. cerevisiae to provide arabinose and xylose utilisatio
