It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

In relation to the development of IT-products it is very important that the software supplier is aware not only of the target group but also the field of application. Usability should characterize the whole IT-design process as, in relation to this context, design includes more than merely those aspects which are visible to and thus can be interpreted by the naked eye. The study examines the specific qualities and properties that substantiate the usability and the demands that a customer rightfully expects from an IT-product. The user and the customer are highlighted in the same context in order to demonstrate that it is through the customer that an IT-product is defined as being useful. Thus, from this perspective, the user and customer can be considered as being the same person.

The purpose is to understand the planning process for residential buildings and toinvestigate the consequences of the choices made in the process. The project will alsoprovide broader knowledge in the design and development under the current law andpractice.The goal is to present a proposal on how a city near the site where water can bedesigned from a sustainable perspective. How can a residential neighborhood be anenvironmentally sound and sustainable region? New systems and techniques havebeen presented previously in terms of sustainable environments and these are intendedof being used in the project Quarter Water-mirror.The project has been implemented on the computer program ArchiCAD in whichdrawings and visualizations have been carried out. These drawings are included asannexes to the report.For information, calculations and drawings, laws for physical planning and Swedishstandard have been followed.Residential buildings have been designed on a site, which is 2, 5 hectares.

Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.

It is found that the properties of the record years of 1965-1975 is leaking a lot of energy andthese properties are facing a major energy efficiency. From the energy aspect, the facade isafflicted with poor thermal insulation which is a big problem. To address this problem addinginsulation is a good alternative to reduce overall energy consumption of a building. Thewindows on these buildings are also a problem from the energy point of view. Therefore,there are many reasons considered for energy upgrading.

The aim of this study was to understand how care staff in residential care perceive and work with elderly mental health and how these perceptions and work is related to aging. We have gathered our empirical material through eight qualitative interviews and vignettes with care staff in residential care. The study was conducted in a municipality with 10 000 to 20 000 inhabitants in southern Sweden. The material was analyzed with use of ageism as a theoretical frame of reference. The results showed that the care staff had different perceptions of mental illness in general and regarding the elderly.

In the year of 2005 the international standard IAS 40 came in to use in Sweden, this lead to an opportunity for the corporations to choose either to evaluate their investment properties according to the historical cost accounting principal. The model contains the obtaining price with reduction for the planned writing off. The alternative that IAS40 offers is the fairvalue principal, which evaluate the investment properties by consideration of the income versus outcome and surrounding factors for every accounting periodSince the fairvalue is buildt on numbers the corporations them self choose what to publish and for how long the value depreciation should be lasting before it should be taken up as an unrealized value change in the reporting material. This means that there is a big chance that the evaluation can be distortedSince we just recently have had strong cyclical variation and are on our way from an excess boom into a weak economic climate, this will be the first study performed about fair value in a weak economic climate since the adoption of IAS40.The purpose of the essay is to find out how well the booked value of investment properties owned by corporations listed on the Swedish stock market accord with the fairvalue that the market and the Swedish property index indicates on. To be able to test this connection we gathered information from the corporation?s annual reports which we compiled to see how the market comprehends.

The purpose of this thesis is to examine the quality notions used by the library personnel responsible for the video game department at Malmo City Library. Furthermore, the thesis aims to assess how these notions of quality relate to properties of the actual collection of video games. The empirical results are based on interviews with the responsible library personnel. The result is then analyzed by an interpretation of Carl Gustav Johannsen?s library adapted, theory-based, model of quality definitions.

The Swedish Red Polled breed is threatened by extinction and there are only around 1100 animals left. The breed was popular in the early twentieth century, but since then the numbers have steadily decreased. The overall objective of this study was to find out whether there may be economic incentives for preserving the breed. The milk quality properties are of major importance in the production of dairy products. Therefore we would like to establish if the Swedish Red Polled breed carries favourable alleles at loci of relevance for milk quality, to potentially make the breed more interesting for milk production.

This is an empirical study mapping out different citation practices to games in the fieldof game studies. From an analysis of 7 journals, 3 conferences and 22 canonical bookswithin game studies, 5 different strategies for game referencing have been identified.Games scholars can either totally refrain from referring to the games they discuss, onlyreference some specific games, cite them as something special and deviant from othersources, refer to them in accordance with other sources or refer to games with regard totheir unique properties as a reference. For the reference librarian working with issuesrelating to game studies the diverse reference practices among game scholars pose aspecific challenge. A challenge that partly can be overcome by knowing how gamescholars frame games and how these frameworks are in conflict with the ways librariansframe and classify sources due their physical properties..

This essay deals with the rationale and aims for doing cultural or aesthetic activities and projects in schools, and gives special focus to a specific group of students, attending schools provided at special residential homes for young people (sa?rskilda ungdomshem). These homes receive young people with psychosocial and substance misuse problems and who show tendencies towards criminal behavior. The essay investigates how working with a cultural project in schools at these residential homes is justified and also elucidates how this specific group of students and their problems are constructed in the documents surrounding the project. The essay will further ponder over possible educational and pedagogical consequences of these constructions.The investigation has its theoretical frame work in curriculum theory.

Hemp is a versatile plant with many uses that has been around for thousands of years. The plant is highly adaptable andwill cultivate in almost any soil. It has excellent remediation properties and has shown to be relatively consistent when itcomes to crop yields. The aim of this literature survey is to examine how hemp can be used to be considered asustainable energy crop in Sweden through database searches and interviews. Hemps characteristics as an energy cropand its remediation properties is evaluated and compared with other plants that are used in Sweden.
