Hur byggnadsdetaljer ändrar fasadens uttryck
An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.
Topografins inverkan på markvattenhalten i ett jordbruksdominerat avrinningsområde
Topography is an important parameter for catchment hydrology, since it is a driver for water flow. Moreover, topography serves as a basis for hydrological models, e.g. ?Top-model?, which is based on a topographical wetness index (TWI). Few studies of TWI have been conducted on agricultural catchment scale.
Four fields were studied in a Swedish drained agricultural catchment in order to evaluate the influence of topography on soil wetness.
Varmt Sköljvatten
In cooperate with Asko Cylinda we have developed a new heat system too short the processtime and reduce the energy consume in a dishwasher and still have it too be a class AAA.The environment and quality is important for the company too still be the number one onthe market, If they want too keep that position the product developed of new innovations willbe very important. The systems we have developed are more effective and reduce energy uptoo 25 %. The process time is reduced too less than two hours, from the today two andhalf-hour. The solutions are too heat up the rinse water and the dishwater at the same time,with a new heating system and it make are solutions unique and effective. Its good for thedish and the environment.
Scientific collaboration kartläggning av ett tvärvetenskapligt forskningsområde inom biblioteks- och informationsvetenskap
The aim of this thesis is to map the research area of scientific collaboration within Library and Information Science LIS. The purpose is to find out who is doing research in this area, who they cite and if they get cited by other scientists outside of LIS. Scientific collaboration is an interdisciplinary research area with researchers from different disciplines such as LIS, human-computer interaction, psychology and sociology. We have concentrated our study to North America, Ireland, Great Britain and Scandinavia. In order to find researchers, we visited the websites of all universities with library and information science faculties in the chosen countries.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
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.
Riksintresse; Bevarande eller nyttjande : Vindkraftsutbyggnad inom Natura 2000- områden
Natura 2000 is part of the European Union: s framework to protect and preserve biological diversity. Natura 2000- areas are by the goverment appointed to areas of national interest for preserving nature. Also wind power stations are appointed as of national interest and the reason for this is the goverments goal to get energy from reneweble energysources. This essay describes when both these intrests conflict eachother when it comes to building wind power stations within Natura 2000- areas. The main focus of this essay is a casestudy of two cases from two different counties, Dalarna- and Norrbotten county, where applications have been made to build wind power stations within existing Natura 2000- ares, both cases have reached the court dealing with enviromental issues.
Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare
Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil.
Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.
Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?
Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.
Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn
This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.
Definitionsproblem i sexualbrottslagen : -bristen i definieringen av begreppet vuxen
AbstractThe ideas of adulthood, adolescence and childhood in Swedish law have a tendency to not be expressed or discussed. This thesis has focused on the preparatory work of the sexual offence-law to see whether it defines adulthood. This has been achieved by analyzing the documents related to this preparatory work. The thesis focused on two central questions: 1) Was the idea of adulthood an integral part of the discussions in the preparatory work 2) If so, then how was it defined and are there any contradictions in the definition. In addition, this work also evaluated the impact of this law and investigated whether the absolute protection intended by the government and the committee of sexual crime seek actually exists.The study shows that the concept of adulthood was not defined specifically in the preparatory work.
Ansvarsfrågan vid fuktspärrsarbete i våtutrymme
This final project is an investigation about the responsibility in rooms where the walls and floors are exposed or partly exposed to irrigation of water, as a bathroom, laundry room and WC. The cost for all water damage is valued for 5 000 000 000 SEK each year. How is this possible with all information about the problem and good materials? Who is responsible? Incites had been made in the subject throw reading reports and participation in courses about how to make a room mention above. Discussions have been made with workers in the trade of making the walls waterproof.The conclusion in the rapport is about who´s responsible for the damages and will pay the cost of the renovation. The responsibility is discussed between the contractor and the insurance company.
Screens : tävling om strandpromenaden i Helsingborg
The competition for the beach promenade in Helsingborg was announced in 2001 and was arranged by the city of Helsingborg. My contribution to the competition represents the main part of my thesis in the Landscape Architecture Programme.
The competition entry is based on the concept of crossing screens of vertical elements which connect the pattern and structure of the city to the beach and the water. The different materials and designs of the screens relate to the various characters of the different parts of the area and they form a sequence and uniting theme along the beach.
In addition to the competition entry which was made in 2001, the thesis contains a second part, made in the spring of 2006. It consists of an Introduction with the competition programme and a description of the starting points, a part called Method where the process is described, and the Conclusion with reflections on the competition entry and the process where I also introduce and comment on some other projects which in different ways have are connected to my concept.

Vad bör sägas? - en begreppsanalys av förändringar i synen på yttrandefrihet
This essay intends to investigate the view on freedom of speech in Sweden. The expanding of the hate crime law rises the question if there is a current changing view on freedom of speech. By comparing motions concerning an expanding of the hate crime law from different periods, I am able to conclude if and how the view on the term freedom of speech has taken place. This is done in a descriptive analysis of terms, where the different values and arguments for a change is compared. The material is taken from the period 1991-1993 and 2000-2001.

Has the neighborhood helped to form their identity?Method: In my data collection I have chosen a qualitative approach with observation and semistructured interviews.
Solenergisystem i Hammarby Sjöstad
Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.
