By having phenotypically plastic traits, many organisms optimize their fitness in response to fluctuating threats. Freshwater snails with translucent shells, e.g. snails from the Radix genus, differ considerably in their mantle pigmentation patterns, with snails from the same water body ranging from being completely dark pigmented to having only a few dark patterns. These pigmentation differences
Close-in planets are in jeopardy, as their host stars evolve off the main sequence (MS) to the subgiant and red giant phases. In this paper, we explore the influences of the stellar mass (in the range 1.5-2M similar to), mass-loss prescription, planet mass (from Neptune up to 10 Jupiter masses), and eccentricity on the orbital evolution of planets as their parent stars evolve to become subgiants a
We present a network of sites across Fennoscandia for optical sampling of vegetation properties relevant for phenology monitoring and satellite data calibration. The network currently consists of five sites, distributed along an N-S gradient through Sweden and Finland. Two sites are located in coniferous forests, one in a deciduous forest, and two on peatland. The instrumentation consists of dual-
Objectives: The aim of this study was to explore the frequency of malnutrition risk and associated risk of falling, social and mental factors among elderly without home-help service. The aim was also to explore factors associated with risk of falling. A cross-sectional design was used. Elderly persons own homes. Data were collected during preventive home visits to 565 elderly (age range 73-90 year
Climate warming will increase the drought exposure of many forests world-wide. It is not well understood how trees adapt their hydraulic architecture to a long-term decrease in water availability. We examined 23 traits characterizing the hydraulic architecture and growth rate of branches and the dependent foliage of mature European beech (Fagus sylvatica) trees along a precipitation gradient (855-
Background: Cardiovascular Magnetic Resonance (CMR) enables non-invasive quantification of cardiac output (CO) and thereby cardiac index (CI, CO indexed to body surface area). The aim of this study was to establish if CI decreases with age and compare the values to CI for athletes and for patients with congestive heart failure (CHF). Methods: CI was measured in 144 healthy volunteers (39 +/- 16 ye
Most state-of-the-art natural gas fired combined cycle (NGCC) plants are triple-pressure reheat cycles with efficiencies close to 60 percent. However, with carbon capture and storage, the efficiency will be penalized by almost 10 percent units. To limit the energy consumption for a carbon capture NGCC plant, exhaust gas recirculation (EGR) is necessary. Utilizing EGR increases the CO2 content in t
Popular Abstract in Swedish Internationalisering av högre utbildning beskrivs i första delen av avhandlingen i ett vidare perspektiv, flera olika forskningstraditioner som berör högre utbildning och internationalisering beskrivs i syfte att utgöra en bakgrund för argument som framhåller ett pedagogiskt och didaktiskt perspektiv som väsentligt i samband med utveckling och konkretisering av en interThe development of higher education in the Western countries involves ideas of internationalisation, included in curricular objectives. Policy-makers stipulate internationalisation ideologies, from a politico-economic perspective, where ideas about flows of various cultural elements are incorporated in visionary idealistic terms. Nevertheless teachers and students and others concerned with higher
The use of mobility devices, such as walking sticks and rollators, increases during the ageing process. Our aim was to explore how very old single-living Swedish women experience the use of mobility devices over time, in relation to everyday occupation. A multiple case study strategy involving quantitative and qualitative data was used. The findings indicate that the use of mobility devices, rolla
Syftet är att studera och analysera processer vars mål är att förändra vardagen för två marginaliserade grupper, så att de i större utsträckning blir delaktiga i samhället. De två undersökta grupperna är manliga unga narkomaner och äldre utvecklingsstörda. Avhandlingen består av tre geografiska perspektiv: 1) det tidsgeografiska synsättet, 2) känslan för platsen och 3) socialgeografiska teorier omThe aim is to study and analyse processes intended to change the daily lives of two marginalised groups and enable them to participate to a greater extent in the community. The two marginalised groups are young male drug addicts and older intellectually disabled. The thesis is permeated by three geographic perspectives: 1) the time-geographic approach, 2) sense of place and 3) social-geographic th
Distribution of responsibility is one of the main focus areas in discussions about climate change ethics. Most of these discussions deal with the distribution of responsibility for climate change mitigation at the international level. The aim of this paper is to investigate if and how these principles can be used to inform the search for a fair distribution of responsibility for climate change ada
How do fungi navigate through the complex microscopic maze-like structures found in the soil? Fungal behaviour, especially at the hyphal scale, is largely unknown and challenging to study in natural habitats such as the opaque soil matrix. We monitored hyphal growth behaviour and strategies of seven Basidiomycete litter decomposing species in a micro-fabricated "Soil Chip" system that simulates pr
Klimatförändringarna med stigande havsnivåer gör att förutsättningarna för vårt byggande måste förändras i kustnära områden. Länsstyrelsen i Skåne har fattat ett beslut om att mark under +3 meter över havet döms ut för bebyggelse. Kommunerna vid kusten får då mycket svårt att expandera, och vill därför kunna hitta eventuella lösningar för att kunna bygga i utsatta lägen. En möjlig lösning är att aWith the climate change sea levels are rising which changes the boundary conditions for sites along the coast. The County Administrative Board of Skåne has decided that new buildings should be built at least 3 meters above sea level. Because of this decision the coastal municipalities have problems with expanding further, and are really keen on finding alternative solutions in order to allow build
The immigrants from China have generally taken over European immigrants to play important role in the North America since 1960s. Based on the human capital theory and neoclassical economic theory, this thesis examines the characteristics of Chinese immigrants who respectively arrived at the United States and Canada since 1990 (cohort 1990-1997 and cohort 1998- 2000). The data is coming from the 20
The aim of this thesis is to better understand Hindu-Christian relations in the experience of North Indian Pentecostals. The study proceeds from a social identity theory (SIT) framework and is guided by three research questions. The research questions call attention to Pentecostals’ perception of the two social groups ‘Christians’ and ‘Hindus’, how the relationship between the two groups is experi

Sammanfattning Studiens syfte var att undersöka ungdomars erfarenheter av att leva i styvfamilj. I studien undersöktes anknytning och sambandet mellan anknytning och självuppfattning. Deltagarna i studien var ungdomar mellan 11-19 år, som hade levt i sin styvfamilj i minst fyra år. Hälften av deltagarna hade en pågående kontakt med Barn och ungdomspsykiatrin och Socialförvaltningen (klinisk grupp)Abstract The aim of this study was to investigate adolescents’ experiences of living in a stepfamily. We explored attachment related thoughts and feelings and their association to self - perception. Participants in the study were teenagers between 11- 19 years old who had lived with their stepfamily for a minimum of four years. Half of the participants had an ongoing contact with the Child and Ado
The notion of “visual framing” has become more sophisticated in the contemporary social media environment and has demonstrated its interrelation with public relations and strategic communication. Past researchers approached visual framing topics from the contents of the resulting frames themselves, ignoring the visual framing constructing processes of one of the frame constructors: public relation
