Human existence and welfare depend on functional ecosystems. Ecosystems are critical to sustain life-support services for human well-being. One method that visualizes that humanity requires ecosystem services for resource consumption and assimilation of produced waste is ecological footprints. This study focuses on the ecosystem service carbon sequestering. A quantification of this ecosystem service showed the potential for accumulation of carbon in different ecosystems in Stockholm and Norrbotten County for the years of 1995 and 2004.

I am in this essay to find out how to successfully combine new development with preservation of natural values, mainly large scale vegetation and ground formations.This is done by studies of three developments. The first development, Engeltofta backe, lies 7 km northeast of Gävle. The expectations of natural preservation were not fullfilled when this area, after the explotation, did not have any vegetation of value left. The second example, Östra Kvarnskogen in the community of Sollentuna, shows, as far as one can tell at the moment, a sucsessful combination of new development and preserved nature. The third example is a development in the community of Kullön. In this area the ambition of combining preservation and development was fullfilled. After studying vital documentation in each planning process, I made interviews with different actors in each of the three processes. I thereafter compared the different documents and answers from the interviewed persons to find out if there were any significant similarities or differences which could be of importence when natural values is to be preserved in new developments. My conclusion of this study is that it is of great importence to define key expressions often used in the process, such as natural values and preservation.

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.

Internationell läxforskning visar ett positivt samband mellan läxläsning och resultat och många lärare bekräftar detta samband. Denna undersökning bygger på föreställningen att graden av läxläsning i gymnasiematematik påverkas negativt av bristande tillgång till läxhjälp vilket i sin tur påverkar resultatet negativt. Syftet med denna studie är därför undersöka i vilken omfattning efterlyser gymnasieelever hjälp med hemläxor i matematik och om eleverna kan tänka sig ta emot den hjälpen över Internet. Resultat visar att en majoritet av elever kan tänka sig att aktivt söka löpande läxhjälp över ett bemannade Internet forum och ännu fler efterlyser samma hjälp inför olika skolprov. Enbart en försvinnande liten del av eleverna utnyttjar läxhjälp som deras skolor erbjuder idag.

The Civil Engineering office in Skellefteå needs to develop the users' participation in the planning of parks and playgrounds. In order to get such a procedure to work one have to find a method that can work in the daily activity. My work aims to find such a method and to implement it in practice. Apart from helping the Parks departement to find an functional method I will also develop a deepened knowledge about users?participation wich can be very useful i my future profession. This work can be divided in three stages.

Considering water quality, landuse and reducion of wetland area in the watershed of Tidan, areas witch are in need of constructions to improve the water quality are identified. Constructions are suggested to be located within the smaller streams in the watershed, so that the water is treated before it reaches the stream Tidan..

Sweden's population holds today one of the highest life expectancies in the world and an increasing number of Swedes believe that they have good health. However, the problem still remains that there exists significant differences in health between different population groups and neighborhoods. Two neighborhoods that demonstrate high inequality in health status are Rinkeby and Danderyd in Stockholm County.    The purpose of this study was to examine why health differs between different neighborhoods and how residents experience the area and their health. To answer this purpose a combination of statistical data and qualitative interviews with residents in Danderyd and Rinkeby has been used with an additional literature review.      The study showed that the causes of health inequalities between these neighborhoods was primarily concerned with the factors of education, economic conditions, ethnicity, conditions of comfort and companionship and the surrounding residential environment. The population in Danderyd, made up largely of people with high education, good economic conditions and few foreign-born, while the majority of Rinkeby?s population consists of individuals with low education, poor economic conditions and a high proportion of inhabitants of foreign origin, which are determining factors leading to poorer health status among the population.

In Örebro, the car traffic share does not tend to decrease. The crowdedness on some of the bus routes is high at times. Investigations show that the residents of Örebro want a city centre whose street environment is more restrictive of car traffic and better for pedestrians, cyclists and public transport. To decrease the car traffic share a rapid, convenient, clear, effective and environmental friendly public transport with high frequency and strong capacity in a short, direct and logical network is needed. A modern tramway fulfils these criteria.At first, this report describes factors that are important to take into consideration when planning a tramway.

 Through teaching, pupils are given the opportunity based on their personal experiences and current events to express and consider their views in relation to others who hold different views. As a result, pupils should be encouraged to get involved and participate in an open exchange of views on societal issues (Skolverket, 2011d, s. 189). To assess pupils orally in the subject of civics in primary education is an unexplored field, which makes this field relevant to explore. There are numerous researchers? who with the help of deliberative methods, formative feedback, formative assessment and studies regarding classroom climates whom all speak positive about using discussion/dialogue in education to upraise and develop learning among pupils.

Syftet med den här uppsatsen är att ta reda på hur och i hur stor utsträckning chattspråket påverkar ungdomars skriftspråk. Då chattspråket ofta är svårt att särskilja från ungdomsspråket behandlas även ungdomsspråkets inverkan på skriftspråket. En följdfråga är om ungdomar har förmågan att inse när det är viktigt att använda korrekt standardspråk och när det passar att använda ett mer avslappnat språk.Skrivandet undersöks både i skolan och på chattspråkets rätta forum, Internet. Enkäter lämnades ut till svensklärare som besvarade frågor om förekomsten av chattspråk och ungdomsspråk, och ett av Sveriges mest välbesökta Internetcommunity för ungdomar besöktes. Dessutom gjordes elevtextundersökningar.

Swedish energy policy aims to increase the use of energy from renewable sources and this should be done in a safe, environmentally and sustainable manner. According to the Energy Agency the use bio-fuel increased by 73% between 1990 - 2006. Stands with high share of slash are often located on areas with high productivity which often are located on soils with poor bearing capacity. This will increase traffic on susceptible soil leading to increased ground damage. To reduce the risk of ground damage at slash-forwarding, ground protection is needed.

Many companies have historically forced their interests through without any thoughts about the future needs of the humans and the society. In the last few years voices have been raised for a change, companies need to take their responsibility regarding sustainable development.The purpose of the report is to describe and explain possible relations between sustainabil-ity performance of companies and profitability, valuation, industry and size respectively.To be able to judge the sustainability performance of the companies Folksam (2006a) have been used. This is a solid investigation of the companies listed on the A- and O-lists of the Stockholm Stock Exchange by the end of 2005. The sustainability marks have been com-pared with the chosen key values for each hypothesis respectively. With this quantitative data as foundation, a quantitative approach and a deductive method have been used.In the first area of the investigation, profitability, the authors found correlation for the main hypothesis between sustainability performance and ?Return on Total Assets? through a statistical test.

Denna studien har undersökt hur bilden av en fantasyskog förändras då man varierar dess grundformer. Undersökningen använde sig av en kvantitativ metod och genomfördes genom en webbenkätundersökning på sex olika forum. Enkäten innehöll sex geometriskt uppbyggda fantasyskogar med varsin geometrisk form som byggsten. De former som användes var uppåtpekande trianglar, liggande rektanglar, cirklar, kvadrater, stående rektanglar och nedåtpekande trianglar. Varje skogsvariant hade tre tillhörande slutna frågor och en öppen fråga för ytterligare kommentarer.Undersökningen visade att förändringen av grundformerna i en fantasyskog kan förändra uppfattningen om den.

The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.
