Urban trees contribute significantly to our society. By providing ecosystem services and a habitat that other urban species and ecosystems depend on, both biodiversity and the people in the city benefit. Some characteristics that the trees possess include functioning as biological filters for the atmosphere and water, as well as positively impacting people's mental health. However, urban trees are challenged by stressors such as pollution and a drier environment, making them particularly sensitive to climate change. The goal of this study was to estimate the expected magnitude of climate change in Gothenburg and compare it with the current urban species' natural climate boundaries to understand the extent of the climate threat and which species appear to be most at risk.

Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and renovation ofold buildings.

The aim of this study was to acquire a greater understanding and knowledge about how care staff at houses with special services for people with intellectual disabilities think and work (handle situations) regarding sexuality. To achieve our goal we carried out nine semi structured interviews using an interview guide. These interviews took place in two different communities in southern Sweden. The theoretical perspectives that were used to analyze the result were Sense of Coherence, Scope of action and Normalization. The result showed that the staff considered sexuality a part of their work and a natural subject to talk about.

The study seeks to investigate and understand how individuals create their identity from the perspective of two countries and cultures, and how these affect their current lives today. The focus of the study is aimed at young adults who have mostly or entirely grown up in Sweden to parents that have migrated. The material is based on seven qualitative, semi-structured interviews. The result is then divided into three themes; ethnic and cultural belonging, life impact, and the preservation and passing on of culture. The derivation of the first theme is that there are mixed views regarding the cultural association of the persons interviewed.

I det här arbetet presenteras en studie från ett projekt som ägde rum i Kolmården djurpark sommaren och hösten år 2003. Projektet bygger på ett uppdrag från jordbruksdepartementet. Det handlade om huruvida grävlingar i fångenskap reagerar i olika stressande situationer. För att kunna undersöka detta har grävlingarnas naturliga beteende studerats under fyra perioder från juni till september samma år. Det som studerats under perioden är grävlingarnas olika beteenden, lokationen i grävlingshägnet samt fysiologiska parametrar så som hjärtfrekvens och kroppstemperatur hos grävlingarna.

En jämförelsestudie har genomförts mellan två värmesystem. Analysen har genomförts med ett flerbostadshus som referensfasighet. Fastigheten är lokaliserad i Södertälje kommun. Analysen går ut på att bestämma vilket värmesystem som är fördelaktigt vid renovering av äldre flerbostadshus med avseende på energi och kostnad. De systemen som har behandlats är ett centralt värmesystem med motströmsvärmeväxlare och ett centralt värmesystem med frånluftsvärmepump.Det centrala värmesystemet (Eq aggregat) är ett centralt från- och tilluftssystem med återvinning (FTX system).

During the nineties, ecological handling of urban storm water became very popular in Sweden. Together with Chalmers University of Technology and two Swedish communities, DHI Water and Environment has been doing research of storm water ponds and constructed wetlands. This thesis work is a part of that research project. The work has been applied at the Bäckaslöv storm water treatment plant in Växjö, Sweden. The plant consists of one storm water pond and a downstream constructed wetland.

Om man vill minimera behovet av köpt energi är det bästa sättet att se till att så lite värme och luft som möjligt läcker ut ur byggnaden. En betydande del av värmen i byggnader med normal standard går förlorad genom det omgivande klimatskalet, det vill säga genom tak, väggar, fönster, dörrar och golv. Hög lufttäthet i en byggnad ger bättre lönsamhet genom att den skapar en bättre inomhusmiljö och ger lägre energianvändning. Det krävs normalt tillskott av energi för att balansera energiförluster av olika slag. En byggnads energianvändning är den energi som köps in för normalt brukande under ett normalår och fastighetsenergi.

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

Background: Ill-health related to unhealthy lifestyle is increasing and despite existing knowledge about healthy lifestyle it is difficult to change behaviour. Counselling in the primary health care is often superficial and without critical elements for behaviour change. Aim: The aim of this paper to elucidate interventions for change of lifestyle with respect diet and physical activity. Method: A literature review was carried out and ten scientific articles were analyzed and compiled in two main categories: design of these interventions and participation in them. Results: Education, decision making, goal setting, feedback, social support and follow-up were identified as critical elements for behaviour change.

Föreliggande rapport redovisar resultat från den svenska pilotstudien inom det internationella s.k. SINR-projektet (Societal Images of Natural Recovery). Detta projekt syftar till ökad kunskap om hur olika synsätt, hos allmänheten såväl som inom olika professionella grupper, påverkar människor möjligheter att komma tillrätta med olika former av missbruk. Som ett första steg i projektet har i hittills sex större städer i fem olika länder ett mindre antal svarande, representerande olika samhällsgrupper, tillfrågats om sin uppfattning om möjligheterna att på egen hand ta sig ur olika slag av missbruksproblem. Den svenska pilotstudien har, på uppdrag av FoU-enheten, av tre socionomstuderande vid Stockholms universitet i form av ett examensarbete.

AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.

This essay is part of a project between Södertörn University College and Stockholm Academic Forum. The focus of the project is gender equality in small- and medium sized companies. I have worked with a construction company called Activa . The majority of the employees at the company were male and I was interested in the consequences of gender construction in such an environment. I think that the basic condition for equality work is an understanding of gender and the male norm.

This thesis examines young people's thoughts about their presence on social media. With asocial constructive approach the study focused on how young people think and act on socialmedia in relation to constructions of gender and normality. The analysis is based on fourgroup interviews with 13-year old boys and girls. The theoretical approach is based partly onsocial constructionism where discourses and ideas of normality are identified and analyzed.Erving Goffman's theory of social interaction was central to illustrate how young peoplepresents themselves based on the prevailing discourses. It is clear that they adjust theirrepresentations of themselves depending on the context.
