Föreningslivets (TUF) och skolans betydelse för turkiska ungdomars identitet : En kvalitativ studie om fem turkiska ungdomars uppfattning om deras identitetskapande
The Swedish society has gone through a radical change. From being a monoculture society it has developed into a multicultural society representing a mixture of people from all around the world. This change has had a significant impact on both the Swedish school system and the teacher?s role. Therefore a subsequent ambition for a multicultural school would be to recognize this diversity and establish guidelines for how to meet each individual students need.
Redovisning i fackförbund : Visar den resultat och ställning?
Background: Sweden is a country with 30 million memberships in different non- profit organizations. In total these organizations employees about 400 000 people, through employment and voluntary work. The complete turnover for non- profit organizations is 100 billion Swedish crowns per year. It has only since 2001 been compulsory to follow the Swedish account rules BFL and ÅRL. Trade unions are one type of non-profit organizations with the main purpose to care for the interest of its members concerning their working condition.
Varnhems tidiga kyrka och kyrkogård : Isotopanalys av skelettmaterialet i området
This paper deals with stable isotope analysis on the children of the early Christian cemetery in Varnhem, Västergötland. Human bone and tooth material from the cemetery has been analysed for stable carbon, nitrogen and sulphur isotopes. The analysis showed that the diet had been homogeneous and that the children had been breastfed, with a possible exception of the child from grave 100..
Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations.
The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.
LIP : en effektivitetsstudie
Lokala investeringsprogram was a subsidy program which supported environmental reforms during the years 1998 to 2002. The subsidies were given to Swedish municipalities. Most of the evaluations of the subsidised projects have now been completed and included in a database.
The purpose with this thesis is to analyse whether the instrument has been effective with respect to carbon dioxide reductions and costs. These calculations have focused on subsidy and cost efficiency. The analysis has been compared with a previous report called "LIP ur ett samhällsekonomiskt perspektiv".
The result shows that the reduction cost for one kg CO2 has been almost one SEK, which is twice as high as the cost reported in a previous report, half a SEK.
Anhörigvårdarens situation
The purpose with this study was to examine how persons giving care to their spouses with dementia experience their life situation. As information source we used a qualitative study which included halfstructured interview questions. The study took place in three municipalities in the south of Sweden. Three females and two males took part in the study and everyone had experiences of giving care to their spouces with dementia. We used a coping theory and an exchange theory.
"Arbeta som god man" - "Work as an administrator"
This study illustrates the task of the administrator where the main focus lies on getting understanding for the administrator?s work, showing how this is performed. The method I have used in the performance of the research is the qualitative method. This study was carried through by means of interviews. Theoretical starting points are exchange theories, friendship theories and part theories.
Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie
The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.
Framtidens stadsträd för en fungerande grönstruktur
The effect of climate change places demands on how we build cities. Cities have to be built denser to meet the objectives of sustainability but as a result of this densification city green areas are at risk of exploitationand disappearing. The question this raises is whether there has to be an opposition between a dense and a green city?Urban trees are playing a very important role in cities. They stand as the major part of the vegetation in citieswhich are otherwise dominated with concrete and stone.
OTEC för Tarawa
Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.

Ett kandidatexamensarbete inom lättviktskonstruktioner .
Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.
De sista entusiasterna? En studie av medborgarnas engagemang under ett decennium i Åsele, Borrby, Hasslarp och Tving
The purpose of this study was to examine how commitment to a cause on a local basis had developed in four smaller groups during one decade. In 1996 I interviewed representatives in Åsele, Borrby, Hasslarp and Tving about their commitment and citizen initiative. Now, ten years later, I followed it up by interviewing them again. I wanted to know if the groups/associations still existed, if they had achieved their goals as they where pronounced ten years ago and how a strong commitment on a local basis can develop during ten years. Which phenomena decide whether the group develop or phase out? I use the term citizen commitment instead of citizen initiative to stress the fact that it is no longer an initiative but an on-going commitment.
Livscykelanalys: Pelletspanna från kvänum energi
This study will identify the environmental impact in terms of carbon dioxide for a boiler house on behalf of Kvänum energi. The boiler central consists of a main building, which in turn contains multiple components such as boilers, pipes, etc, the boiler central uses pellets fuel. It also includes a silo and an ash container. The total weight of the boiler is about 63 tons. Each boiler has an output of 600 kW; the central includes three boilers with room for a fourth if necessary.
Hållbara uppvärmningsalternativ för Grinda Wärdshus : En studie om uppvärmning med pellets och flis
This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.
