Temperature conditions and heat fluxes in ice covered lakes are discussed analyzing measurements in eight Swedish lakes. Heat fluxes from sediments and heat fluxes from water to ice are determined from temperature profiles. The contribution of solar radiation is estimated from heat-budget calculations. It is found that the heat content of most of the lakes changes very little when they are ice cov
Social visions to replace fossil fuels with renewable energy sources have motivated unprecedented growth in global renewable energy manufacturing. Previous literature shows that people committed to realizing such visions have difficulties reconciling with the negative social-ecological impacts of this mass production even if it presents a formidable challenge to a socially just and ecologically su
When most of us think of solar technology, we picture photovoltaic panels on sunny rooftops capturing clean energy for self-sufficient households. This vision suggests that increasing the installation of solar panels will reduce greenhouse gas emissions and encourage more democratic energy pathways. But the way solar technology relates to global environmental and social problems is actually very d
Resuspension of inorganic sediments in a very shallow Swedish lake is studied using settling sediment traps and measurements of suspended matter. Theoretical aspects of resuspension dynamics is discussed emphasizing special shallow lake aspects. Bottom shear stress distribution is computed for different wind conditions.
Reliable quantitative vegetation reconstructions for Europe during the Holocene are crucial to improving our understanding of landscape dynamics, making it possible to assess the past effects of environmental variables and land-use change on ecosystems and biodiversity, and mitigating their effects in the future. We present here the most spatially extensive and temporally continuous pollen-based r
Prediction and evaluation of pollution of the subsurface environment and planning remedial actions at existing sites may be useful for siting and designing new land-based waste treatment or disposal facilities. Most models used to make such predictions assume that the system behaves deterministically. A variety of factors, however, introduce uncertainty into the model predictions. The factors incl
The finite element model was successfully applied to predict the Pb-210 and total extractable fatty acid concentrations at different depths in two sediment cores from Lake Ontario by using different transport parameters. The transport parameters were computed from Pb-210 data. These parameters were used to simulate the total extractable fatty acid concentrations at different depths. The computed r
I denna artikel ställer jag frågor till arkivmaterial ur vardagstrycket: ett antal mäklarbroschyrer och reklamutskick analyseras med fokus på husdrömmar. Vilka husdrömmar gestaltas? Vem antas bo här, hur, var och varför? Vem är husdrömmaren, vilken värld, tid, människa och bostadskultur framträder i materialet? Jag jämför material från 1970- och 1980-tal med slutsatser jag dragit i min forskning o
Covid-19-pandemin blev en global kris med konsekvenser för såväl offentliga och kollektiva som privata och individuella vardagspraktiker. Svenska universitet fick med kort varsel lägga om all undervisning så att den kunde utföras på distans. Bidragen i denna antologi består av en samling berättelser skrivna utifrån ett antal universitetslärares undervisningsvardag under en omvälvande tid. De repreA collection of teacher's stories about their pedagogical problems and solutions during the covid-19 pandemic
INTRODUCTION: The surprise question (SQ) "Would I be surprised if this patient died within the next xx months" can be used by different professions to foresee the need of serious illness conversations in patients approaching end of life. However, little is known about the different perspectives of nurses and physicians in responses to the SQ and factors influencing their appraisals. The aim was to
Phytochromes belong to a group of photoreceptor proteins containing a covalently bound biliverdin chromophore that inter-converts between two isomeric forms upon photoexcitation. The existence and stability of the photocycle products are largely determined by the protein sequence and the presence of conserved hydrogen-bonding interactions in the vicinity of the chromophore. The vibrational signatu
