Comparative ecosystem - atmosphere exchange of energy and mass in a western Russian and a central Siberian bog. I) Interseasonal and interannual variability of energy and water fluxes

Energy and latent heat fluxes λE were measured over ombrotrophic bogs in European Russia (Fyodorovskoye) and in central Siberia (Zotino) using the eddy covariance technique, as part of the EuroSiberian Carbonflux Project. The study covered most of the snowfree periods in 1998, 1999 and 2000; in addition some data were also collected under snow in early spring and late autumn 1999 and 2000. The sno

Approximating Decoding Thresholds of Punctured LDPC Code Ensembles on the AWGN Channel

In this paper, we provide an efficient way to predict iterative belief propagation (BP) decoding thresholds of randomly punctured low-density parity-check (LDPC) code ensembles on the binary-input additive white Gaussian noise channel (AWGNC), given only the BP threshold of the mother code ensemble on the binary erasure channel (BEC) and the code design rate. We show that the predictions are accur

Oskyldighetspresumtionen

Oskyldighetspresumtionen är en grundläggande straffprocessuell princip som i korthet innebär en rätt för misstänkta och tilltalade att bli behandlade som oskyldiga fram till en fällande dom. Presumtionen kan även i vissa fall sträcka sig utanför själva processen. Två till synes svårförenliga intressen står mot varandra vid tillämpningen av oskyldighetspresumtionen; säkerställandet av en effektiv

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

Föreställningar om det förflutna. Arkeologi och rekonstruktion

Popular Abstract in Swedish Avhandlingen behandlar försök att i full skala återge hur det förflutna kan ha tett sig. Som objekt för undersökningen har jag valt stenåldersbyar, bronsåldershus, järnåldersmarknader, vikingafestivaler och medeltidsveckor. Några skånska exempel är Glimmingehus medeltidsfestival, vikingabyn i Hög och Fotevikens vikingareservat, företeelser som med utgångspunkt i en platThe purpose of this dissertation is to discuss full-scale historical reconstruction in Denmark, Norway and Sweden. In recent years we have seen an accelerating interest among the public to visit reconstructed places with reference to ancient times. Reconstructions from the Stone Age to the Middle Ages are discussed. The emergence of reconstruction is presented in an historical overview of the phen

Shrinkage of High-Performance Concrete.

This paper outlines an experimental and numerical study on the effect of w/c, silica fume and age on shrinkage of High-Performance Concrete (HPC). Cylinders of 8 types of HPC were cast. Carbonation and water-losses were studied parallel. Internal relative humidity (RH) and strength were investigated on cubes from the same batches of HPC that was used in the studies of shrinkage. The results indica

Skrivande som handling och möte - gymnasieelever om skrivuppgifter, tidsvillkor och bedömning i svenskämnet

Popular Abstract in Swedish Syftet med avhandlingen är att belysa hur elever i gymnasiet hanterar skrivuppgifter, tidsvillkor och bedömning i svenskämnet och klarlägga hur villkoren för skrivandet återverkar på elevers självbild avseende skrivande. Det empriska materialet består av skriftliga och muntliga intervjuer, fokusgruppsamtal, observationer och elevtexter och är insamlat under en period soThe purpose of this dissertation is to explore how students in upper secondary school can feel, react and cope with writing tasks, time conditions and assessment in the subject of Swedish. The study deals with two upper secondary classes from different schools, one at a natural science programme, one at an aesthetical programme with music as an area of emphasis. The empirical material consists of

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

Impact Assessment of Developed Applications – Overall interactIVe Assessment

interactIVe introduces active intervention safety systems in order to increase traffic safety. The interactIVe functions are – depending on their purpose – able to brake and steer autonomously. Furthermore, the driver is continuously supported by interactIVe assistance systems which warn the driver in potentially dangerous situations. Seven demonstrator vehicles – six passenger cars of different v

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
